Embodiments of the present application will be further described with reference to the accompanying drawings.

Example one

Referring to fig. 1 and 2, a first embodiment of the present application provides amovable carrying device 010 for carrying long-length objects, such asfan blades 030, so as to transport the long-length objects over long distances. Comprises afirst bearing part 100, a mounting assembly, asecond bearing part 300, atelescopic part 500 and a connectingpiece 600.

The mounting assembly includes a mountingmember 200 and an adjusting member, the mountingmember 200 is hinged to thefirst bearing portion 100 through a hinge shaft to achieve a movable connection with thefirst bearing portion 100, the mountingmember 200 is used for mounting ablade root 031 of thefan blade 030, and enables thefan blade 030 to move relative to thefirst bearing portion 100 at least in one direction to achieve an adjustment of the posture of thefan blade 030. Thesecond bearing portion 300 has a bearing surface for bearing theblade body 033 of thefan blade 030. Thestretchable part 500 connects thefirst bearing part 100 and thesecond bearing part 300, and thefirst bearing part 100 can be relatively close to or far from thesecond bearing part 300 by stretching and retracting thestretchable part 500. The connectingmember 600 is disposed at an end of thefirst bearing part 100 away from thesecond bearing part 300, and is used for receiving a driving force and pulling thefirst bearing part 100, the mountingmember 200, and thesecond bearing part 300 to move on the ground.

Referring to fig. 3, the adjusting element includes an adjustingelement 400, and the adjustingelement 400 is used to adjust the posture of thefan blade 030 in one direction. The positioningmember 400 is connected to the mountingmember 200 and thefirst bearing portion 100, and thepositioning member 400 is used for driving the mountingmember 200 to drive thefan blade 030 to move in a direction close to or far away from thesecond bearing portion 300. Theinstallation component 200 and thepositioning component 400 are matched to enable thefan blade 030 to rotate around the hinge shaft on thefirst bearing part 100 relative to thefirst bearing part 100 through theinstallation component 200, so that the included angle between thefan blade 030 and thefirst bearing part 100 is changed, thefirst bearing part 100 and thesecond bearing part 300 are connected through thetelescopic part 500, and the whole length of themovable bearing device 010 can be adjusted.

When thefan blade 030 is far away from the second receiving portion 300 (i.e. far away from the ground) by the adjustment of thepositioning member 400, the projection of thefan blade 030 on the ground is shortened, and at this time, the distance between the first receivingportion 100 and thesecond receiving portion 300 is shortened, so that the bearing surface on thesecond receiving portion 300 is close to thefan blade 030, and the bearing surface can continue to provide support for thefan blade 030. Since the position of thefan blade 030 on thefirst bearing part 100 can be changed by the positioningmember 400, and the distance between thefirst bearing part 100 and thesecond bearing part 300 can be adjusted, the overall gravity center position of themovable bearing device 010 can be greatly changed, which leads to easy tipping during the movement of themovable bearing device 010, and therefore, the connectingmember 600 is disposed on thefirst bearing part 350, so that theblade root 031 is close to the connectingmember 600 receiving the driving force. Through letting the holistic focus offan blade 030 be close to the position that portable load-bearing device 010 received drive power, can improve portable load-bearing device 010's stability, in addition through the partial gravity ofblade root 031 for the first load-bearing member 350 that receives drive power has relatively great pressure contact in ground, avoids portable load-bearing device 010 to be close to the position of drive power and is pried byfan blade 030 and lift, leads to being difficult to through the friction displacement with ground.

To ensure a stable connection of the mountingmember 200 to thefan blade 030, the mountingmember 200 includes aflange 210 and aclip 230. Theflange 210 has a mountingsurface 211 for attaching to the end surface of ablade root 031, and the mountingsurface 211 is for attaching to the end surface of theblade root 031. The terminal surface ofblade root 031 also theblade root 031 keeps away from the one side ofblade body 033, and this terminal surface has many splice bars of level and smooth reference surface and protrusion reference surface, andinstallation face 211 is in order to guarantee the support ofblade root 031, in order to avoid damaging the splice bar again, consequently can set up a plurality of holes of stepping down onring flange 210 and pass for the splice bar. After the connecting ribs are inserted into the receding holes, the reference surface part of the end surface of theblade root 031 is attached to the mountingsurface 211, so that the mountingsurface 211 provides good support for thefan blade 030. Whenfan blade 030 is locatedportable loading attachment 010, still need carry out position adjustment through settingpart 400, consequently theinstalled part 200 only supports theblade root 031 and can't realize thatinstalled part 200 drivesfan blade 030 and move, and clamp 230 sets up and carries out further fixed tofan blade 030 onring flange 210. Theyoke 230 is generally annular, a clamping space is formed in the middle to clamp the outer circumferential surface of theblade root 031, in order to apply a clamping force to the entire outer circumference of theblade root 031 by theyoke 230, theyoke 230 includes ahead portion 231 and atail portion 233, wherein thetail portion 233 can slide relative to thehead portion 231 to change the size of the clamping space, and when the clamping space is reduced to a certain position and sufficient clamping force is provided for the outer circumference of theblade root 031, fixing the relative positions of thehead portion 231 and thetail portion 233 can fix theyoke 230 and theblade root 031 relatively.

After thefan blade 030 is fixed by the mountingmember 200, thefan blade 030 is integrally rotated by the aligningmember 400, and since thefan blade 030 has a large weight, the aligningmember 400 needs to apply a force large enough to move thefan blade 030. The positioningmember 400 uses a hydraulic cylinder, one end of the hydraulic cylinder is connected to thefirst bearing part 100, the other end of the hydraulic cylinder is connected to the mountingmember 200, and the hydraulic cylinder is perpendicular to the hinge shaft of the mountingmember 200 and thefirst bearing part 100, so that the mountingmember 200 rotates relative to thefirst bearing part 100 through the extension and contraction of the hydraulic cylinder, and the mountingmember 200 synchronously drives thefan blade 030 to rotate relative to thefirst bearing part 100. The quantity of pneumatic cylinder can not do the restriction, but generally sets up two pneumatic cylinders in the bilateral symmetry ofinstalled part 200, can guarantee through two hydraulic stems that the atress is balanced so that more smoothly stable whenfan blade 030 rotates.

Specifically, one end of the hydraulic cylinder is connected to thefirst bearing part 100, and the other end is connected to one end of the mountingmember 200 away from the hinge shaft. Thefan blade 030 is driven to rotate around the hinge shaft by the mountingmember 200 through the extension and retraction of the hydraulic cylinder. Thefan blade 030 is rotated around an axis perpendicular to the mountingsurface 211 by arotary driving member 700 in the adjusting member, specifically, therotary driving member 700 includes abase plate 710 and a drivingmotor 730, wherein thebase plate 710 is fixed to thefirst bearing portion 100, an annular sliding groove is provided on thebase plate 710, an annular slidingblock 213 is provided on one surface of theflange 210 facing thebase plate 710, and the annular slidingblock 213 is provided in the annular sliding groove to enable theflange 210 to rotate around an axis perpendicular to the mountingsurface 211 relative to thebase plate 710. The inner ring of theflange 210 is further provided with gear teeth (not shown), the drivingmotor 730 is fixed to thechassis 710, and the output end of the drivingmotor 730 is provided with a gear, and the gear is engaged with the gear teeth so that the gear can drive theflange 210 to rotate when rotating. When the gear is meshed with the gear teeth, the moment arm of the drivingmotor 730 is the radius of the gear, the moment arm of theflange plate 210 is the radius of the gear teeth, and the radius of the gear teeth is far larger than that of the gear, so that the power requirement of the drivingmotor 730 can be reduced, and the motor with lower power can drive thefan blade 030 to move integrally. Thefan blade 030 rotates around an axis perpendicular to the mountingsurface 211, so that the wind resistance of thefan blade 030 when themovable carrying device 010 moves on the ground can be changed, the wind resistance can be reduced, thefan blade 030 can be prevented from being separated from the mountingmember 200, and on the other hand, themovable carrying device 010 can be driven by smaller driving force to realize faster transportation speed.

Thefan blade 030 can be rotated by theturntable 130 in addition to being rotatable about an axis perpendicular to the mountingsurface 211 and being rotatable relative to thefirst carrier 100 by the hinge of the mountingmember 200 to thefirst carrier 100. Specifically, the adjusting member further includes a rotating table 130, the rotating table 130 is rotatably disposed on thebase frame 110 of thefirst bearing portion 100, and the mountingmember 200 is fixedly disposed on the rotating table 130, so that the rotating table 130 can drive the mountingmember 200 to rotate when rotating, and the mountingmember 200 can drive thefan blade 030 to rotate relatively. Specifically,bed frame 110 includesfirst section 111 of keeping away from the setting of second load-bearing part 300 and thesecond section 113 that is close to the setting of second load-bearing part 300, revolvingstage 130 rotationally sets up onfirst section 111, the pneumatic cylinder setting deviates from the one side ofsecond section 113 atinstalled part 200, and the articulated shaft sets up the one end that is close tosecond section 113 atinstalled part 200 again, can drive the articulated shaft synchronous revolution when making revolvingstage 130 rotate, be provided with the arc wall in the position thatsecond section 113 is close tofirst section 111, the both ends setting of articulated shaft makes the articulated shaft can follow the rotation and the motion of installedpart 200 in the inner wall of arc wall. The rotary table 130 drives thefan blade 030 to rotate, so that the gravity action line of thefan blade 030 is close to or far away from thesecond bearing portion 300, when themovable bearing device 010 bears thefan blade 030 to move on the ground and turn, the gravity center position of thefan blade 030 can be adjusted in advance to match with the turning, the gravity center of thefan blade 030 can be relatively close to the turning center when thefan blade 030 turns, and the possibility that themovable bearing device 010 turns over is reduced. On the other hand, thefan blade 030 can also be rotated by theturntable 130 so that thefan blade 030 can avoid obstacles during transportation.

Thetelescopic part 500 connecting the firstload bearing part 100 and the secondload bearing part 300 includes a plurality ofextension pieces 510. Thefirst carrier part 100 is connected to theextension piece 510 at one end, and thesecond carrier part 300 is connected to theextension piece 510 at the other end. Theextension members 510 are substantially plate-shaped, and have flanges at both sides thereof, and twoadjacent extension members 510 are slidably disposed, so that the twoadjacent extension members 510 can have an overlapped state and an unfolded state by relative sliding. The overlapped state means that the projections of the two extendingmembers 510 on the ground have a larger overlapped part, and the unfolded state means that the projections of the two extendingmembers 510 on the ground have a smaller overlapped part or even do not overlap. When the twoextension pieces 510 are in the unfolded state, the interval between thefirst bearing part 100 and thesecond bearing part 300 may be increased, and the substantially plate-shapedextension piece 510 may insulate thefan blade 030 from the ground. By isolating thefan blade 030 from the ground, objects on the ground can be prevented from being carried up, and further the surface of thefan blade 030 can be scratched. When theexpansion part 500 is in the expanded state, the expansion part has a longer length, the stress of thesecond bearing part 300 can form a larger moment, the blade root of thefan blade 030 is arranged at the position close to the driving force, and thefirst bearing part 100 can be prevented from being pried by goods, so that the pressure between the position close to the driving force and the ground is reduced, and the driving efficiency is influenced. When the two extendingmembers 510 are overlapped, the distance between thefirst bearing part 100 and thesecond bearing part 300 can be reduced.

In order to allow themovable carrier 010 to carry thelarge fan blade 030, the overall length of thetelescopic portion 500 and thesecond carrier 300 may be 30000mm or more in the expanded state of thetelescopic portion 500, and 9000mm or less in the overlapped state.

When themovable bearing device 010 is used for bearing alarger fan blade 030, the size of themovable bearing device 010 can be further designed, for example, when thetelescopic portion 500 is in the expanded state, the overall length of thetelescopic portion 500 and thesecond bearing portion 300 reaches above 40000mm, and when thetelescopic portion 500 is in the overlapped state, the overall length of thetelescopic portion 500 and thesecond bearing portion 300 reaches below 10000 mm.

It should be noted that the size of themovable carrying device 010 can be designed reasonably according to the size of thefan blade 030 to be transported, and is not limited to the above size.

In order to drive theadjacent extension members 510 to be switched between the overlapped state and the unfolded state so as to drive the first carryingpart 100 and the second carryingpart 300 to move relatively close to or away from each other, thetelescopic part 500 further includes a telescopic control member (hidden by a flange, not shown), and the telescopic control member may use a hydraulic cylinder, or may use other structures such as a screw pair. When a lead screw pair is used, a lead screw is connected to oneextension piece 510, a lead screw nut is disposed on theother extension piece 510, and theextension piece 510 provided with the lead screw nut is made to approach or separate from theextension piece 510 provided with the lead screw by rotation of the lead screw.

The end of theshaft 033 of thefan blade 030 facing away from theblade root 031 is supported by thesecond bearing 300 in order to reduce the moment experienced at the mounting 200. However, since thefan blade 030 can rotate about an axis perpendicular to the mountingsurface 211, thefan blade 030 can rotate relative to thefirst bearing portion 100 through the hinge joint of the mountingmember 200 and thefirst bearing portion 100, and can also move relatively closer to or away from thesecond bearing portion 300 through the rotary table 130, the relative positional relationship between thesecond bearing portion 300 and thefan blade 030 is dynamic. In order to provide a stable bearing for the end of theairfoil 033 of thefan blade 030 facing away from theblade root 031 in a dynamic environment, thesecond bearing 300 comprises a mountingplatform 310 and abearing 350. The mounting table 310 is connected to thetelescopic part 500 to be relatively close to or far from the first carryingpart 100, and a mountingsurface 211 is provided on the mounting table 310. The mountingsurface 211 is provided with a guide groove extending in a direction toward the first carryingpart 100, that is, in a direction parallel to a line connecting the first carryingpart 100 and the second carryingpart 300. Thecarrier 350 is slidably engaged with the guide groove such that thecarrier 350 can move relatively close to or away from thefirst carrier portion 100 when sliding along the guide groove. When the position of thefan blade 030 changes relative to thesecond bearing portion 300, the bearingmember 350 slides along the guide groove for a certain distance to match the position change of thefan blade 030, so that the bearing surface on the bearingmember 350 can provide stable support for thefan blade 030.

Referring to fig. 3 and 4, when thefan blade 030 needs to be assembled and disassembled, the position of themovable carrying device 010 needs to be fixed, and in order to prevent themovable carrying device 010 from being displaced due to rolling of thewheel body 900, thetelescopic part 500 is provided with thetelescopic part 800, and the telescopic direction of thetelescopic part 800 is perpendicular to the telescopic direction of the telescopic control part, so that themovable end 801 of thetelescopic part 800 can be abutted against the ground, thereby preventing themovable carrying device 010 from moving relative to the ground through static friction force between themovable end 801 and the ground, and simultaneously providing an additional supporting point to prevent themovable carrying device 010 from rolling over. A flat plate may be disposed at themovable end 801 of thetelescopic member 800 to increase the contact area of themovable end 801 with the ground, so that themovable carrying device 010 has higher stability when being fixed. It should be noted that although the function of thetelescopic member 800 is described here as an example of fixing themovable carrying device 010 on the ground, themovable carrying device 010 may be fixed on a square, a dock, or the like, in which case themovable end 801 of thetelescopic member 800 contacts a supporting surface of the square, the dock, or the like opposite thereto. In addition, the number of thetelescopic pieces 800 can be four, six, and the like, and the increase of the number of thetelescopic pieces 800 can avoid the situation that a fewtelescopic pieces 800 cannot support the ground, which causes difficulty in providing supporting force for themovable bearing device 010.

In order to prevent thetelescopic member 800 from tilting themovable carriage 010, thetelescopic member 800 needs to be as far away from the ranges of thefirst carriage 100, thetelescopic member 500, and thesecond carriage 300 as possible to provide a support area as large as possible so that the center of gravity of themovable carriage 010 is located in the support area. Therefore, theexpansion member 800 is connected to theexpansion part 500 through an expansion member, and theexpansion part 500 is provided to an end of the expansion member, by which theexpansion part 500 can be relatively distant from theexpansion part 500 to expand a support area.

Referring to fig. 5, themovable carrying device 010 inevitably encounters jolt during carrying and transporting of thefan blade 030, thefan blade 030 may be separated from the support of the carrying surface in case of jolt, and even a large moment may be formed to separate from the fixing of the mountingmember 200 in case of an excessively large swing amplitude. In order to avoid theblower blade 030 from making a relatively large displacement relative to thesecond bearing portion 300 due to a jolt, the bearingmember 350 includes aframe body 351, a first limitingmember 353 and a second limitingmember 355. Wherein theframe body 351 is in sliding fit with the guide groove, the first limitingmember 353 is fixed on theframe body 351 to form a bearing surface which is substantially parallel to the ground so as to bear thefan blade 030, the second limitingmember 355 is arranged on theframe body 351, so that a limiting gap for inserting theblade 033 is formed between the first limitingmember 353 and the second limitingmember 355, when bumping occurs, thefan blade 030 can be prevented from being separated from a limiting space of the bearingmember 350 due to the limitation of the second limitingmember 355, and therefore thefan blade 030 is prevented from being separated from the mountingmember 200 due to a large moment.

In order to enable themovable bearing device 010 to run on a running road surface with driving force driving, themovable bearing device 010 further includes awheel body 900. Thewheel 900 is disposed on thefirst bearing portion 100 and thesecond bearing portion 300, so that the overall center of gravity of themovable bearing device 010 is located between thefirst bearing portion 100 and thesecond bearing portion 300, thereby ensuring the overall stability of themovable bearing device 010.

In practical use of such a movable carriage 010: theblade root 031 of thefan blade 030 is hoisted to a position close to theflange 210, and theblade root 031 of thefan blade 030 is fixed through theflange 210 and thehoop 230. Theframe 351 of thecarrier 350 slides along the guide slot to a suitable position so that the bearing surface of thefirst stop 353 abuts against theblade 033 of theblower blade 030, and the position of thesecond stop 355 is adjusted so that theblade 033 of theblower blade 030 is in a stop gap having a suitable size. Themovable carrying device 010 is connected to theheadstock 050, and themovable carrying device 010 is provided with driving force through theheadstock 050 so that themovable carrying device 010 can move on the carrying bottom surface. When thefan blade 030 receives a large wind resistance in the transportation process, thefan blade 030 rotates by controlling the drivingmotor 730, so that the wind resistance of thefan blade 030 is adjusted, when thefan blade 030 encounters a narrow turning, thefirst bearing portion 100 and thesecond bearing portion 300 are relatively close to each other by thetelescopic portion 500, the overall size is reduced, in addition, the angle of thefan blade 030 relative to thefirst bearing portion 100 is adjusted by the adjustingmember 400, so that the gravity center of thefan blade 030 is approximately between thefirst bearing portion 100 and thesecond bearing portion 300, and the bearingmember 350 can also be displaced by the guide groove to maintain the attachment of thefan blade 030 so as to provide a supporting force. When a large and sharp turn is encountered, the position of the gravity action line of thefan blade 030 close to the turning center can be adjusted through the rotary table 130, so that the tipping is avoided. In addition, when the vehicle encounters an obstacle during traveling, the obstacle can be avoided by adjusting the position of thefan blade 030.

It should be noted that thewheel 900 may be replaced with a crawler belt, and themovable carriage 010 may travel on the ground.

Thewheel body 900 may be provided only on thefirst bearing part 100, theextendable part 500, or thesecond bearing part 300, or any two or three of them. It is sufficient that thefirst support unit 100, theextendable unit 500, and thesecond support unit 300 can be supported on the ground as a whole.

It should be noted that theretractable member 800 may also be disposed on thefirst bearing portion 100 or thesecond bearing portion 300 to provide support, as long as themovable end 801 can abut against the supporting surface, and thewheel body 900 is separated from the supporting surface to fix the position of themovable bearing device 010.

Through themovable bearing device 010, thefan blade 030 can effectively avoid obstacles in the transportation process, and thefan blade 030 is accepted and dispersed to be prevented from being damaged. The adjustable distance between thefirst bearing part 100 and thesecond bearing part 300 may in turn enable thefan blade 030 to pass through various types of curves during transportation.

Example two

Referring to fig. 6, a second embodiment of the present application provides amovable carrying device 010, where themovable carrying device 010 differs from the first embodiment in that:

asupport arm 131 extending in a direction away from the ground is provided on theturntable 130, and the middle of the mountingmember 200 is hinged to the top of thesupport arm 131 through a hinge shaft. A through hole is formed at a position of thesupport arm 131 close to theturntable 130, and thepositioning member 400 passes through the through hole and is hinged to a side of the mountingmember 200 close to theturntable 130. The end of thepositioning member 400 facing away from the mountingmember 200 is hinged to thesupport arm 131. The rotation of the mountingmember 200 about the hinge axis at the middle position thereof is controlled by the extension and contraction of thepositioning member 400.

EXAMPLE III

Referring to fig. 7 and 8, a first embodiment of the present application provides a transportation cart for carryingfan blades 030 for long-haul transportation. This transport cart comprises acart head 050 and amovable carrier 010 provided in the first embodiment. Theheadstock 050 is detachably connected with the connectingpiece 600, and themovable bearing device 010 is provided with driving force through theheadstock 050, so that themovable bearing device 010 drives thefan blades 030 to move on the ground.

In order to realize that thevehicle head 050 drives themovable carrying device 010 to turn, thevehicle head 050 also needs to be rotatably connected with themovable carrying device 010, so the connectingpiece 600 comprises a bearing, thevehicle head 050 is provided with a connecting column perpendicular to the ground, and the connecting column is inserted into the bearing to enable thevehicle head 050 to be rotatably connected with themovable carrying device 010. The connection angle of thevehicle head 050 and themovable bearing device 010 can be changed through the rotatable connection, so that the transport vehicle can turn conveniently.

In order to enable theheadstock 050 to effectively receive themovable carrying device 010, thefirst section 111 and thesecond section 113 of thebase frame 110 are subjected to stepping treatment, namely thefirst section 111 is far away from the ground compared with thesecond section 113, so that the part of theheadstock 050 can extend into the position below thefirst section 111, and the connection between theheadstock 050 and themovable carrying device 010 is more stable.

In addition, in order to enable the driver or the transport vehicle to know the gravity center condition so as to make adjustment in time, the transport vehicle further comprises a monitoring system, the monitoring system monitors the gravity center position range of the transport vehicle, and guides the adjustment of the posture of thefan blade 030 by obtaining the result of the gravity center position range, or enables thetelescopic piece 800 to be telescopic, so that the transport vehicle is prevented from tipping due to too much deviation of the gravity center.

The monitoring system obtains the pressure layout of the transport vehicle by monitoring the tire pressure data of the wheel body, and then obtains the approximate range of the gravity center position through the pressure layout calculation, namely the gravity center position is in the projection range of the transport vehicle on the ground or outside the projection range of the transport vehicle on the ground. In order to make the gravity center position range obtained by the monitoring system accurate and effective, a multipoint arrangement pressure sensor is needed. The monitoring system comprises pressure sensors arranged at least two positions, pressure conditions of different positions are obtained through the pressure sensors arranged at different positions, and then a relatively accurate gravity center position range is calculated, so that the overturning of the transport vehicle can be accurately and effectively prevented by adjusting the posture of thefan blade 030 and stretching thetelescopic piece 800 aiming at the gravity center position range.

The transport vehicle can effectively avoid the obstacles in the transport process of thefan blades 030, and accept dispersion to avoid damage to thefan blades 030. The adjustable distance between thefirst bearing part 100 and thesecond bearing part 300 may in turn enable thefan blade 030 to pass through various types of curves during transportation.

In addition, other changes may be made by those skilled in the art within the spirit of the present application, and it is understood that such changes are encompassed within the scope of the present disclosure.
