[0002] With the development of science and technology, robots are gradually being used in the power industry to replace operators in some dangerous operations. However, due to the high location of overhead lines, the complexity of the lines, especially the crisscrossing distribution lines, the application of robots in the industry is greatly limited. At present, the robots used in the overhead lines of the power grid are put online by carrying the robots on insulated bucket trucks or by using manual climbing to mount the robots on cables. Therefore, there are the following problems:

[0003] 1. The insulated bucket car is large in size and has a limited range of movement. It cannot work if it encounters a lakeside or a complex line section, which has great limitations;

[0004] 2. Because most construction operations nowadays are carried out without power outages, there is a safety hazard of electric shock when workers are in close contact with live wires during high-altitude mounting;

[0005] 3. The current mounting method is complicated to operate, which reduces the operating efficiency.

[0006] Due to the above problems, the intelligentization process of overhead power lines has been hindered, and no effective solution has been found. Therefore, it is necessary to design an easy-to-operate robot synchronous belt on-line device to reduce the difficulty of operation, improve the operation efficiency and scope of application, and avoid the safety hazards caused by high-altitude operations.
