The springs 6 are extended and retracted to adapt to different convex and concave conditions, thereby reducing friction and ensuring that the wire can slide smoothly. This structure not only improves the stability and safety of the operation, but also effectively prolongs the service life of the wire. The two auxiliary pulleys 7 under each group of pulleys 5 increase the contact area, further reduce the friction on the wire, and improve the working efficiency of the entire system.

[0024] In this embodiment, a linear slide 4 is provided below the pulley 5. The linear slide 4 is powered by a motor 8. The linear slide 4 enables the auxiliary pulley 7 to move vertically up and down on the linear slide 4 through a slider 3 to reach a suitable position.

[0025] Specifically, the linear slide rail 4 includes a shell, a screw rod and a moving block. The screw rod and the moving block are located inside the shell. The output shaft of the motor 8 is connected to the bottom end of the screw rod. A threaded hole is provided in the middle of the moving block. The screw rod is threadedly connected to the moving block. The outer wall of the moving block is fixed to the slider 3 by bolts.

[0026] Furthermore, there are four springs 6, which are symmetrically arranged on both sides of the auxiliary pulley 7. The auxiliary pulley 7 is fixed to the outside of the slider 3 through a bracket. The surface of the bracket is provided with vertical strip holes. A positioning shaft is installed on the outside of the auxiliary pulley 7. The positioning shaft passes through the strip hole on the bracket, and the top of the spring 6 supports the positioning shaft.

[0027] Furthermore, the middle portion of the outer wall of the pulley 5 is an inwardly concave arc structure.

[0028] Furthermore, the limiting groove 2 is a trumpet-shaped structure with a socket at one end, the positioning protrusion 1 is a cylindrical structure with a cone at one end, and the positioning protrusion 1 and the limiting groove 2 are plug-fitted.

[0029] Furthermore, the slider 3 is a U-shaped structure, the slider 3 is clamped on the shell of the linear slide rail 4, and the slider 3 is slidably connected to the shell of the linear slide rail 4.

[0030] Furthermore, the axis of the pulley 5 is rotatably connected to the outer shell of the linear guide rail 4 via a rotating shaft.

[0031] Furthermore, a vertical guide hole is provided on the outer shell surface of the linear slide rail 4, and a guide block is installed on the outer wall of the slider 3 near the outer shell of the linear slide rail 4, and the outer side of the guide block is slidably connected to the guide hole.

[0032] Furthermore, the surface of the auxiliary pulley 7 is provided with an inwardly recessed arc structure, and the curvature of the arc structure is adapted to the curvature of the outer wall of the guide.

[0033] When the utility model is used, when the overhead ground wire reinforcement block installation robot docking device of the power transmission network is broken, two ground wire walking robots start from the cross arm heads on both sides of the tower respectively and walk along the ground wire to the two ends of the broken point.

[0034] During the walking process, the combination of the pulley 5 and the auxiliary pulley 7 arranged at the upper end of each robot effectively reduces the friction with the ground line, so that the robot can move smoothly and efficiently on the uneven ground line. In particular, the design of the auxiliary pulley 7 adapts to the different convex and concave conditions of the ground line through the expansion and contraction of the springs 6 arranged around it, which significantly reduces the friction and ensures the smooth movement of the robot.

[0035] When the two robots reach the appropriate position of the strand break, they precisely plug and match the positioning protrusion 1 and the limiting groove 2 set at the end to achieve docking. After the docking is completed, one robot carries the upper part of the reinforcement block, and the other robot carries the lower part of the reinforcement block. The two robots work together to thread and crimp the reinforcement block with the broken strand.

[0036] During the crimping process, the auxiliary pulley 7 can move in the vertical direction through the cooperation of the linear slide 4 and the slider 3 to adapt to the height change during crimping and ensure the accuracy and stability of crimping. The motor 8 provides power for the linear slide 4, drives the slider 3 to move along the linear slide 4, and thus drives the auxiliary pulley 7 to rise and fall.

[0037] After the reinforcement block is installed, the two robots work together again to perform the final crimping reinforcement on the reinforcement block and the steel strand to ensure that the reinforcement effect reaches more than 90% of the tensile strength before breaking. After completing all the set actions, the two robots return to the starting point autonomously and wait for the next operation instruction.
