After the automatic coating equipment or the robot and other equipment are loaded on the bare conductor 100, the auxiliary conveying device needs to be taken down from the bare conductor 100 so that the automatic coating equipment or the robot and other equipment can walk on the bare conductor 100, at this time, the loading mechanism 41 is controlled to descend to the ground, then the insulating lower pull wire 409 is pulled outwards, the bare conductor 100 is made to be separated from the installation opening 405, and the insulating upper pull wire 408 is slowly loosened until the skip car 40 descends to the ground.

Since the lifting wire 407 is connected to the lifting base 413 through the wire passing hole 443, the loading mechanism 41 is more stably maintained in the vertical state.
In order to make the vertical sliding block 431 be well matched with the bare conductor 100, in this embodiment, a wire clamping groove 432 for clamping the bare conductor 100 is formed at the top end of the vertical sliding block 431.
