Abstract

The invention discloses a lifting cross arm for hot-line work and an application method of the lifting cross arm. The lifting cross arm comprises a lifting cross arm body, a cross arm base and a quickinserting type torsion crank. The lifting cross arm body is arranged at one end of the cross arm base. The quick inserting type torsion crank is arranged at the other end of the cross arm base. The lifting cross arm body is used for adjusting and controlling the lifting height of the lifting cross arm body. The cross arm base is used for being connected with the lifting cross arm body and the quick inserting type torsion crank. The lifting cross arm has the advantages that operation space is large, mounting and dismounting are easy, connecting is reliable, and the use effect is good; the replacement time is short; the work strength is low; wires can be placed well; it is guaranteed that the wires are spaced by safe distance; the problems of wire falling, electric leakage, short circuits and the like are avoided; and insulation cross arms of proper lengths can be matched according to needs.

Description

technical field [0001] The invention relates to a cross arm, in particular to a lifting cross arm for live work and a method for using the same. Background technique [0002] In the process of electric power maintenance, it is often encountered that the insulator is damaged and needs to be replaced. In the past, the replacement method was mostly after a power outage, and the operator climbed to the position where the insulator was located to manually repair and replace it. This replacement method is not only efficient It is also easy to be limited by the working space; although there are currently methods of using protective equipment and operating tools to replace insulators with live electricity, these live replacement methods are easy to touch the wires during the replacement process, and there are certain safety hazards. [0003] The crossarm is an important part of the pole tower. Its function is to install insulators and fittings, to support the wires and lightning con...
