[0002] Cables are important cable products used to transmit and distribute high-power electric energy in power systems, covering various voltage levels from 1kV to 500kV and above, as well as power cables of various insulation types. These cables are laid outdoors and, as the backbone lines of the power system, play a vital role in the stable transmission and distribution of electricity. Since the cables are laid outdoors all year round, harsh environmental conditions (such as strong winds, heavy rains, lightning, high temperatures, low temperatures, etc.) often affect their service life. Sometimes, severe weather can even cause direct damage to overhead cables, thus affecting the normal transmission of electricity. In the event of a cable break, the two disconnected cable ends are far apart on the ground, making it inconvenient to dock and maintain. The two cable ends need to be pulled close to each other for docking, which requires multiple pole climbing operations, which is time-consuming and labor-intensive, and poses a greater safety risk.

[0045] When the present invention is in use, the moving wheel 2 at the bottom of the vehicle body 1 is used to move the equipment to the vicinity of the maintenance position, and the two support brackets 9 are adjusted to the same direction as the cable 36, so that the support brackets 9 and the wire clamp 10 are close to the cable 36 to be repaired, and the two ends of the cable 36 are placed inside the wire clamp 10. The clamping force is adjusted by the cooperation of the eccentric disk 21 and the adjustment head 29, and the cable 36 is tightly clamped under the action of the clamp block 32 and the wire clamping claw 35 of the wire clamp 10. The lifting frame 4 is driven to rise by the driving box 3, and the lifting frame 4 drives the telescopic rod 6 to rise through the connecting rod 8, thereby driving the support bracket 9 to move upward, and the wire clamp 10 drives the cable 36 to move together with the support bracket 9 to a suitable height.
