[0002] Line construction is one of the most critical processes in power transmission lines. Traditional line construction is either done by dragging the line on the ground with shoulders or by construction workers manually operating simple tension machines, traction machines and other traditional mechanical equipment. After searching, the application number "CN201721890052.6" discloses "a pulley for automatic locking of UAV power line", which records that "the power line can be guided into the groove of the pulley unit when the pulley unit is fixed on the frame, and the one-way bearing and gear are used to prevent the power line from falling off, which solves the problems of more manual work and low efficiency of line construction, and reduces the impact of the line construction environment and bad weather on the line construction". However, there are still the following problems in actual use:

[0003] In actual use, using a method to fix the pulley and the wire at the same time can easily lead to a situation where the force is too large and the wire is prone to fall off, and intelligent control detection cannot be used during use.

[0004] Based on this, it is extremely practical to provide a pulley that can realize separate fixation of the pulley wires and can realize intelligent control detection. Utility Model Content
