And S4, moving the trolley to enable other wheels 10 to be dismounted on the right side of the bottom of the trolley to move to the pit position on the right side of the bottom of the trolley, and repeating the operation steps S2 and S3 to realize the dismounting of the corresponding wheels 10.
The trolley wheel mounting method adopts the trolley wheel dismounting tool to mount, and comprises the following steps:
(1) Taking a wheel 10 on the right side of the bottom of a mounting trolley as an example, lifting and moving away a pit cover plate on the right side below the trolley by a travelling crane, transversely moving away a detachable track on a right I-shaped steel beam 4, pressing the right part of a left pressing plate 11 on the top surface of the left part of the track beam 5 on the left part of the top surface of a lower flange of the I-shaped steel beam 4 on the right side below the trolley, pressing the left part of the right pressing plate 11 on the right part of the top surface of the lower flange of the I-shaped steel beam 4, fixing the right end of the track beam 5 on the right inner wall of the pit, arranging a plurality of travelling wheels 13 on the front side on the right part of the track beam 5 on the front side, and arranging a plurality of travelling wheels 13 on the right part of the track beam 5 on the rear side, as shown in fig. 2;
(2) Lifting a new wheel 10 onto a supporting platform 902 and clamping the wheel 10 through a clamping plate 904, wherein the clamping part 9 drives the clamped wheel 10 to rotate 180 degrees along with the supporting part 7 around the vertical axis of the turntable 6, the supporting platform is shown in fig. 13, the clamping part 9 rotates 45 degrees clockwise relative to the supporting part 7 through a rotating shaft 8 by holding a pressing handle 901, the wheel 10 rotates from an upright position to a rightward inclined position close to the right I-beam 4, a first safety pin is inserted into a second pin hole 16 and a first pin hole 15 to prevent the clamping part 9 from rotating relative to the supporting part 7, the walking device is moved leftwards, the wheel 10 is moved onto the upper flange top surface of the right I-beam 4, the first safety pin is taken off, the supporting part 7 is driven to ascend by shaking a lifting screw 14, the clamping part 9 is matched with the supporting part 7 to rotate the wheel 10 from the rightward inclined position to the upright position, the supporting platform 902 is placed on the upper flange top surface of the right I-beam 4, the second safety pin is inserted into a fourth pin hole 18 and a third pin hole 17 to prevent the clamping part 9 from rotating relative to the supporting part 16, and the supporting part 7 is shown in fig. 16;
(3) The hand-operated lifting screw 14 drives the supporting part 7 to lift, the supporting part 7 drives the clamping part 9 to lift, the wheel 10 is lifted to a wheel 10 mounting station, the wheel 10 is fixed to a wheel 10 shaft at the right pit position of the bottom of the trolley through screws, the wheel 10 is detached from the clamping part 9, and then the lifting device, the travelling device, the clamping part 9 and the supporting part 7 are controlled, so that the trolley wheel dismounting tool is reset to the state of the step 1;
(4) And (3) moving the trolley to enable other wheels 10 on the right side of the bottom of the trolley to be axially moved to the pit position on the right side of the bottom of the trolley, repeating the operation steps (2) and (3) to realize the installation of the corresponding wheels 10, and after all the wheels 10 on the right side of the bottom of the trolley are installed, evacuating the trolley wheel dismounting tool.
When the trolley wheel dismounting tool is used for dismounting and mounting the left wheel 10 at the bottom of the trolley, the trolley wheel dismounting tool is only required to be turned over 180 degrees on the horizontal plane, the rail beam 5 is fixedly connected with the left I-shaped steel beam 4, and then corresponding operations are carried out according to the trolley wheel dismounting method and the trolley wheel mounting method.
In general, labour saving and time saving when adopting this platform truck wheel dismouting frock to dismantle and install platform truck wheel, and then can improve dismouting efficiency, in addition dismantle with the in-process easy operation and safe and reliable of installing platform truck wheel, can improve the operation security, and this platform truck wheel dismouting frock's application scope is wide, is applicable to the condition of single or multiunit wheel dismouting to personnel input reduces, thereby can reduce the enterprise labor cost.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
