[0002] When installing high-voltage lines, cable operators need to carry climbing tools to climb to the cross arm of the tower, drag the cable to the cross arm of the tower through the upward slide, open the upward slide lock, and move the cable to the insulating bottle by manpower. Since the cable installation process requires working at an altitude of more than 15 meters, the overall weight of the cable is very heavy, requiring operators to lift the cable with both hands, which consumes a lot of physical strength, and requiring both feet to maintain high-altitude balance, making the operation process very dangerous. In order to facilitate the installation of high-voltage cables with insulating bottles, special auxiliary transition devices are used in the prior art to assist in the installation.

[0004] In actual use of the transition device in the above application, the applicant found that: during the actual installation operation, when personnel are transitioning and installing the high-voltage cable to the insulating bottle, they need to manually lift the high-voltage cable from the wire wheel to the jack, and then use the jack to lift the high-voltage cable to a height that matches the insulating bottle, and then manually lift the high-voltage cable and move it to the insulating bottle to complete the transition installation of the high-voltage cable. The entire installation operation requires manual lifting and moving multiple times, which is very troublesome and affects the installation efficiency. In order to solve the above problems, an auxiliary transition device for erecting high-voltage cables is proposed. Utility Model Content
