When the electric power personnel overhauls, the safety belt buckle worn by the electric power personnel is first connected with the fixing ring 4 at the end of the cable 3. In the process of climbing the power transmission tower by the electric power personnel, the first servo motor 5 drives the winch 2 to rotate to drive the cable 3 to gradually tighten so as to keep the cable 3 in synchronization with the electric power personnel. With the climbing of the staff to the top of the power transmission tower, the cable 3 is gradually tightened. In the process of work of the electric power personnel, the staff is pulled and protected by the cable 3 and the fixing ring 4. Since the cable 3 is tightened, it limits the electric power personnel. When the staff steps off, the staff can be pulled by the cable 3 and the fixing ring 4 to prevent falling during the maintenance process. Compared with the traditional anti-falling device, the fixed point of the safety belt does not need to be frequently changed. With the change of the position of the electric power personnel, the cable 3 is retracted and released.

[0029] The utility model works as follows:

[0030] During work, the box 1 is first installed at the bottom of the power transmission tower through the supporting plate 20, then the limiting assembly is installed on the surface of the power transmission tower, then the cable 3 is connected with the limiting assembly in sequence, and finally the end of the cable 3 is pulled back to the ground for fixation. When the electric power personnel are overhauling, the safety belt buckle worn by the electric power personnel is first connected with the fixing ring 4 at the end of the cable 3. During the climbing of the electric power personnel on the power transmission tower, the first servo motor 5 drives the reel 2 to rotate to drive the cable 3 to gradually tighten, so that the cable 3 keeps synchronization with the electric power personnel. As the worker climbs to the top of the power transmission tower, the cable 3 is gradually tightened. During the work of the electric power personnel, the worker is pulled and protected by the cable 3 and the fixing ring 4. Since the cable 3 is tightened, it limits the electric power personnel.

The cable 3 will not be twisted or shaken in a large range during the winding and unwinding, and the cables 3 will not be entangled with each other. The use is safer. The anti-slip pad 9 enhances the friction and protects the cable 3 and the limiting buckle 8, so that the cable 3 and the limiting buckle 8 will not be abraded with each other, preventing the damage of related components.

[0032] During the winding and unwinding of the cable 3, the second servo motor 16 drives the threaded rod 15 to rotate, and drives the connecting block 13 and the adjusting buckle 14 to move back and forth along the top of the box 1, thereby adjusting the position of the cable 3, facilitating the uniform winding of the cable 3 on the reel 2, and preventing the cable 3 from being scattered.

[0033] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
