[0002] In power infrastructure construction, substations are crucial for power transmission and distribution, and their internal structure directly impacts system stability. Cable trenches, as protective pathways for cables, must balance protection and ease of maintenance. Traditional cable trenches often utilize concrete covers, favored for their durability, pressure resistance, and fire resistance. However, their heavy weight increases the difficulty and inconvenience of construction, installation, and maintenance.

[0003] In existing technology, due to the compact and obstructed nature of substation sites, large cable transport vehicles have difficulty accessing the cable trench area for operations. Therefore, workers typically use cover slab transporters to transport concrete cover slabs to the cable trench area for subsequent laying. However, due to the heavy weight of the cover slabs, placing them on the cover slab transporter shifts the center of gravity forward, requiring excessive effort from workers during movement and resulting in low work efficiency.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1 and Figure 2 As shown, a cable trench cover transport vehicle includes a vehicle frame 10, a hoisting structure 20 and a counterweight adjustment assembly 30.

[0030] Among them, the lifting structure 20 is arranged at the front end of the frame 10, and the lifting structure 20 is rotatably connected to the frame 10. By adjusting the frame 10, the frame 10 can drive the lifting structure 20 to move during the movement, so that the lifting structure 20 lifts the cover to be transported.

[0031] The counterweight adjustment assembly 30 is slidably disposed at the rear end of the vehicle frame 10 . By adjusting the counterweight adjustment assembly 30 , the counterweight adjustment assembly 30 can move along the front-rear direction of the vehicle frame 10 .

[0032] In the embodiment of the present application, the lifting structure 20 realizes the rapid lifting of the cover plate to be transported, reduces the direct contact between workers and the cover plate, effectively reduces the risk of injury caused by improper handling operations, and enhances safety; at the same time, it also greatly reduces the burden of manual handling and improves the overall work efficiency; in addition, the counterweight adjustment assembly 30 provided on the frame 10 exhibits a high degree of flexibility and stability, allowing workers to flexibly adjust the center of gravity of the frame 10 according to the load conditions, so that the center of gravity of the frame 10 moves backward, which is convenient for workers to adjust the frame 10 and ensure that workers maintain a stable driving state during the transportation of the cover plate.

[0033] In a possible embodiment, the lifting structure 20 may include a rotating portion 21 and a forked portion 22 .

[0034] One end of the rotating portion 21 is rotatably connected to the front end of the vehicle frame 10 . In the embodiment of the present application, the rotating portion 21 is hung on the front end of the vehicle frame 10 .

[0035] The other end of the rotating portion 21 is fixedly connected to the forked portion 22 . The rotating portion 21 and the forked portion 22 may be integrally connected or fixed by bolts.

[0036] Among them, the rotating part 21 can include a vertical section and an inclined section. The vertical section is perpendicular to the surface formed by the fork-raising part 22. The top of the vertical section is hung on the frame 10, and the bottom of the vertical section can be integrally connected to the inclined section. The bottom of the inclined section is integrally connected to the fork-raising part 22.

[0037] The fork-lifting portion 22 is distributed in a horizontal direction. The fork-lifting portion 22 can insert or remove the cover to be transported during the movement of the rotating portion 21.

[0038] In the embodiment of the present application, during use, a worker first lays two pads on the ground, then uses a crane to place the cover plate on the two pads, leaving it suspended above the ground. The worker then moves the frame 10 toward the cover plate. When the fork 22 encounters the cover plate, it is blocked and rotates synchronously with the rotating portion 21, continuing to move the frame 10 until the fork 22 passes over the cover plate. When the fork 22 is no longer blocked, it rotates naturally, and the frame 10 is adjusted so that the fork 22 penetrates the bottom of the cover plate, completing the lifting of the cover plate.

[0039] By setting a lifting structure 20 at the front end of the frame 10, it is convenient to insert or remove the cover to be transported as needed. The operation is simple and only one worker is needed to complete the transportation of the cover to the required place, which greatly improves work efficiency.

[0040] In a possible embodiment, the counterweight adjustment assembly 30 includes a slide rail 31 and a counterweight slider 32 .

[0041] The slide rail 31 can be fixed to the vehicle frame 10 by bolts or welded to the vehicle frame 10 , and the counterweight slider 32 is slidably disposed on the slide rail 31 .

[0042] In an embodiment of the present application, when the cover plate is lifted, the overall center of the frame 10 can be changed by adjusting the counterweight slider 32, so that the center of gravity of the frame 10 moves backward, making it easier for workers to adjust the frame 10 and ensuring that the workers maintain a stable driving state during the process of transporting the cover plate.

[0043] In a possible embodiment, the counterweight adjustment assembly 30 further includes a driving member 33 .

[0044] The base of the driving member 33 is rotatably set on the frame 10. The driving member 33 can be a hydraulic telescopic rod. The driving end of the hydraulic telescopic rod is rotatably connected to the counterweight slider 32. By adjusting the hydraulic telescopic rod, the driving end of the hydraulic telescopic rod can drive the counterweight slider 32 to move along the direction of the slide rail 31 until the slide rail 31 moves to the desired position.

[0045] In the embodiment of the present application, the driving member 33 is provided to facilitate adjustment of the position of the counterweight slider 32 on the slide rail 31 , thereby improving the convenience and flexibility of workers in adjusting the counterweight slider 32 .

[0046] In a possible embodiment, the counterweight adjustment assembly 30 may further include a locking member 34 . By adjusting the locking member 34 , the locking member 34 may fix the counterweight slider 32 on the slide rail 31 .

[0047] In a possible embodiment, the locking member 34 is a locking bolt or a locking structure.

[0048] In the embodiment of the present application, the locking member 34 is set as a locking bolt or a locking structure, which ensures the stability of the counterweight slider 32 during transportation and further enhances the safety and reliability of the frame 10.

[0049] In a possible embodiment, a handrail 11 is provided at the rear end of the frame 10 , and the handrail 11 can be integrally connected to the rear end of the frame 10 .

[0050] The armrest 11 can be configured as a telescopic rod, one end of which can be sleeved on the armrest 11 , and the other end of which can be used by workers to adjust the length.

[0051] The frame 10 is also provided with a spirit level 12 , the base of which can be fixed to the frame 10 by bolts. Workers can adjust the level of the frame 10 according to the horizontal state of the spirit level 12 .

[0052] In this embodiment of the present application, an adjustable telescopic rod is added to the rear end of the frame 10, increasing the lever length and making it easier for workers to control the frame 10 during transportation. A level 12 is also installed on the frame 10 to display the level of the frame 10 in real time, helping the operator to adjust the counterweight in a timely manner to ensure smooth transportation.

[0053] In a possible embodiment, a support frame 13 is further provided at the rear end of the frame 10 . The support frame 13 is located at the bottom of the frame 10 . The support frame 13 can be fixed to the frame 10 by bolts or welded to the frame 10 .

[0054] In the embodiment of the present application, the support frame 13 is provided to provide additional stability for the frame 10, especially when parked for a long time or with a heavy load, which can effectively prevent the frame 10 from tilting and improve the safety of operation.

[0055] The working principle of the embodiment of the utility model is as follows:

[0056] When in use, workers first lay two pads on the ground, and then use a crane to place the cover on the two pads so that the cover is suspended above the ground.

[0057] The worker moves the carriage 10 toward the cover. When the fork 22 encounters the cover, it is blocked. The fork 22 rotates synchronously with the rotating portion 21, and the carriage 10 continues to move, passing the cover. When the fork 22 is no longer blocked, it rotates naturally, and the carriage 10 is adjusted so that the fork 22 enters the bottom of the cover, completing the lifting of the cover.

[0058] The counterweight slider 32 is adjusted according to the level 12, and then moved to the designated position to achieve leveling of the level 12. Then, the locking member 34 is adjusted to secure the counterweight slider 32 to the slide rail 31. Finally, the worker adjusts the frame 10 and hoists the cover plate to the designated position.

[0059] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
