Referring now to the drawings, specific embodiments of the present application will be described in detail. What has been described herein is merely a preferred embodiment in accordance with the present application and other ways in which the present application may be practiced will occur to those of skill in the art and are intended to be within the scope of the present application.

The cable layingapparatus 100 disclosed herein enables cable transportation and laying work to be performed using mechanical means as shown in fig. 1, reducing labor costs during the period, while also reducing cable damage that occurs when manually hauling cables. In addition, with thecable laying device 100 disclosed in the present application, the laying environment of different electric devices can be adapted, thereby improving the efficiency of cable laying. Specifically, in fig. 1, the cable laying device is capable of laying the cable at a certain height at a certain angle and length to a position most convenient for the electric equipment by means of mechanical driving.

As can be seen with reference to fig. 1 and 2, thecable laying device 100 comprises a cable laying section with areference section 11 and an adjustable length extension 12, a turnover mechanism 20 and apositioning adjustment mechanism 30. In particular, thereference section 11 and the extension section 12 are connected at the longitudinal ends so as to be able to rotate relative to one another and so as to be able to accommodate and transport the laid cables. In particular, the elongate section can be provided at one longitudinal end or at both longitudinal ends of the reference section, as required. In this case, the extension 12 can be extended from thereference section 11 in a targeted manner depending on the operating environment of the consumer. In order to further achieve flexibility in use of thecable laying device 100, thecable laying device 100 further includes apositioning adjustment mechanism 30, wherein thepositioning adjustment mechanism 30 includes arotation component 31, which can be connected to thereference section 11, for example, at one longitudinal end or at a certain longitudinal position of thereference section 11, so that thereference section 11 or the cable laying portion can be rotated by the rotation component, thereby adapting to different installation positions of the electric equipment. Thecable laying device 100 comprises a turnover mechanism 20, wherein the turnover mechanism 20 is connected with thereference section 11 and the extension section 12, so that the extension section 12 can be driven to turn over at different angles from thereference section 11 according to use requirements, different heights and different lengths of the whole cable laying part are realized, and different cable laying possibilities can be presented.

Here, it should be noted that, in the present application, the "longitudinal position" of thereference segment 11 refers to a position in the longitudinal direction of thereference segment 11 or the elongated segment 12.

Optionally, in order to enable thecable laying device 100 to better adapt to electrical equipment of different heights for cable laying, thepositioning adjustment mechanism 30 may further have alifting unit 32 for adjusting the height of the cable laying section. In order to avoid interference with the rotational movement of the cable assembly at the same time, therotary assembly 31 can be arranged on thelifting unit 32 and thelifting unit 32 can be connected to the cable assembly or thereference section 11 via therotary assembly 31. In this case, the rotatingassembly 31 can rotate the reference section or the cable laying section around the liftingunit 32.

In particular, therotary assembly 31 may alternatively be designed as a gear assembly known from the prior art, wherein the gear assembly may be driven by an external motor or other drive mechanism, and the output thereof may be connected to thereference segment 11 and bring thereference segment 11 into a rotary motion.

Alternatively, as shown in FIG. 3, canting mechanism 20, which carries elongate section 12 in a canting motion, may include acanting drive 21 and alinkage assembly 22 driven thereby. Specifically, thelink transmission assembly 22 includes afirst link member 221 and asecond link member 222, wherein one end of thefirst link member 221 is connected with thereference section 11, and the other end is pivotally connected with thesecond link member 222, while the other end of thesecond link member 222 is connected with the extension section 12, and the reference section and the extension section are connected by apivot shaft 13, so that thefirst link member 221, thesecond link member 222, thereference section 11 and the extension section 12 can form a four-bar linkage. In this case, thetumble drive section 21 is connected to and drives the pivot shaft between thefirst link member 221 and thesecond link member 222 to perform a linear reciprocating motion, so that thesecond link member 222 drives the extension 12 to perform a tumbling motion.

Alternatively, the tiltingdrive 21 can also be connected to and carry thefirst link element 221 connected to thereference section 11 into a rotary reciprocating movement, so that thesecond link element 222 carries the extension section 12 into a tilting movement.

Within the scope of the present application, thetumble drive section 21 may alternatively be configured to comprise a tumble drive hydraulic cylinder, wherein thepiston 211 of the tumble drive hydraulic cylinder may be connected with the connecting rod rotating assembly, i.e. the pivot axis between the first and second connectingrod elements 221 and 222 or the first connectingrod element 221, so as to achieve driving of the connectingrod transmission assembly 22.

In the context of the present application, tilting means 20 may be arranged in the longitudinal direction ofpivot axis 13 betweenreference section 11 and extension section 12, for example in pairs at both longitudinal ends thereof, in order to achieve a more stable and balanced tilting movement.

Since thecable laying device 100 is in operation, the cable laying section is often present at a certain height in the form of an elongated load carrier, in order to maintain the height of the elongated cable laying section, thecable laying device 100 disclosed herein may optionally further comprise aheight maintaining mechanism 40, whichheight maintaining mechanism 40 may be provided jointly with the liftingunit 32 of thepositioning adjustment mechanism 30 and maintain the desired height of the cable laying section. Specifically, theheight holding mechanism 40 may have one end connected to thepositioning adjustment mechanism 30 and the other end connected to thereference segment 11, specifically, connected to a longitudinal position of thereference segment 11 outside the installationpositioning adjustment mechanism 30 or the rotatingassembly 31, and support and hold the height of the cable laying part. That is, theheight keeping mechanism 40 may exist in a direction inclined with respect to the longitudinal direction of the cable laying part.

In this case, alternatively, thepositioning adjustment mechanism 30 may be provided at one longitudinal end of the cable laying section or thereference segment 11. While theheight holding mechanism 40 can support the cable laying section at another longitudinal position of thereference segment 11, thereby improving the stability of the cable laying section. For example, it is conceivable that theheight maintaining mechanism 40 comprises a hydraulic cylinder, in which a piston is connected to thereference section 11 and supports the cable laying section by a telescopic movement.

To facilitate transport ofcable laying apparatus 100, it may also include acarrier mechanism 50. In this case, it is conceivable that the support means 50 comprise a semi-trailer, a vehicle-mounted structure or a skid, while the positioning adjustment means 30 can be fixedly placed on achassis 51 of the semi-trailer, the vehicle-mounted structure or the skid.

In the case of the presence of the support means 50 or of the semitrailer, truck-mounted structure or skid mounting, when the cable laying section is rotated through an angle of 90 degrees or more relative to the support means 50, it is likely that the center of gravity of the entirecable laying device 100 will shift away from the support means 50 and towards the cable laying section. Thus, in order to also stably hold thecarrier mechanism 50 in the above working condition, thecable laying device 100 may optionally comprise a liftingleg assembly 60 for stabilizing thecarrier mechanism 50, which comprises at least one liftingleg 61 supporting thestable carrier mechanism 50 by a lifting movement or a telescoping movement. The lifting legs can be attached at both lateral sides of a semitrailer, truck structure or skid-mounted chassis 51 (as shown in fig. 1 or 2). Depending on the degree of rotation of the cable laying section relative to thechassis 51, the lifting legs are configured to be rotatable by different angles relative to thechassis 51, so that an optimum support stability of the support means 50 is achieved.

Furthermore, in the context of the present application, the direction of connection between the elongate section 12 and thereference section 11 is not limited. That is, at the longitudinal ends of the elongate section 12 and thereference section 11, the elongate section 12 may comprise an elongate section attached to the longitudinally extending surface of thereference section 11 or an elongate section attached at the lateral side of thereference section 11. In other words, when the extension 12 is connected to the longitudinally extending surface of thereference segment 11, the extension 12 can lie on thereference segment 11 without being "stretched" or "flipped", whereas when the extension 12 is connected to both lateral sides of thereference segment 11, the extension 12 can rest against the lateral sides of thereference segment 11 without being "stretched" or "flipped".

According to the cable laying device disclosed by the application, the power supply of cables of a plurality of electric equipment can be realized very conveniently and efficiently. As shown in fig. 1, depending on the location and site limitations of the consumer, the cable laying device can have its cable laying section or reference section together with the extension section rotated by a certain angle (e.g. 90 degrees in fig. 1) by means of the rotating assembly, and the height of the cable laying section is adjusted by means of the lifting unit, so that the rotational position and height of the cable laying section are more suitable for connecting the consumer. Meanwhile, according to the number of the electric equipment and the height of the connecting piece of the electric equipment, the extension section of the cable laying part can be correspondingly turned over for a certain angle from the reference section, and a certain inclination is formed to supply power to the electric equipment through cables. Therefore, the cable laying device disclosed by the application not only can efficiently lay the cable, but also can reduce the abrasion of the cable by bearing the protection cable through the cable laying part.

The foregoing description of various embodiments of the present application is provided for the purpose of illustration to one of ordinary skill in the relevant art. It is not intended that the present application be limited to only a single disclosed embodiment. As above, various alternatives and modifications of the present application will be apparent to those of ordinary skill in the art in light of the above teachings.
