Abstract

The invention discloses a new type of special ladder for replacing tension bar insulators, which includes a first ladder body, a telescopic unit and a second ladder body. The first ladder body includes a hollow cross bar, a first stud, a first pedal, a V-shaped A column, a second rotating shaft and a slot, the telescopic unit includes a rotating structure, a buckle, and a second square column, and the second ladder body includes a first arc-shaped hook, a connecting piece, a rotating buckle and a second pedal. The device of the invention ensures the safety of the maintenance personnel during work, and at the same time brings convenience to the maintenance personnel. By switching between two different forms of the ladder, the maintenance personnel can perform maintenance more conveniently and reduce the risk of potential safety hazards. .

Description

technical field [0001] The invention relates to a ladder, in particular to a special ladder for replacing tension bar insulators. Background technique [0002] To replace the 35-110kV tension rod insulators during a power outage, the maintenance personnel need to stand upside down on the insulators with their feet up and their heads down. If the time is too long, the operator has a great safety risk during the work of overhauling the insulator. Therefore, a safe and convenient special ladder is needed. Contents of the invention [0003] The purpose of this section is to outline some aspects of embodiments of the invention and briefly describe some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and titles of this application, to avoid obscuring the purpose of this section, the abstract and titles, and such simplifications or omissions should not be used to limit the scope of the invention. [0004] In view...
