Moreover, for cables that have faults, operating personnel need to hoist the cables in the cable trench for maintenance. The cables cannot be protected during hoisting, which easily causes secondary damage to the faulty cables and affects the subsequent use of the cables. SUMMARY

[0010] As a further optimization scheme of the present application, the distance adjusting mechanism comprises a mounting plate connected with the vertical plate, a stand arranged on the upper end of the mounting plate and a servo motor, a rotating shaft arranged at the output end of the servo motor and extending into the stand and connected with the inner wall of the stand through a bearing, two screw grooves arranged on the outer surface of the rotating shaft and used for winding the first rope and the second rope respectively, a rotating shaft arranged on the stand and below the rotating shaft, a guide wheel movably sleeved on the rotating shaft and used for guiding and pulling the first rope.

[0017] 1. In the present application, the distance adjusting mechanism, the vertical plate, the first rope, the second rope and the V-shaped plate are arranged to adjust the length of the hoisted cable while the two hooks are hoisting the cable.
