Problems solved by technology

[0002] At present, when replacing composite linear insulator strings on power transmission lines, two sets of tools must be used: the upper cross-arm ladder and the backup protection rope to prevent the wire from falling off. There are many tools and complicated operations, which is not conducive to safe production.
Currently, there is no elimination of such devices

Abstract

The invention provides a transmission line multiple-purpose wire off prevention backup device which comprises a U-shaped ring. A protective rope is fixed on the U-shaped ring. The upper section of the protection rope is equipped with a protective rope extension adjuster. A plurality of pedal rope sleeves are fixed on the protective rope from up to down. The bottom horizontal rope body of each pedal rope sleeve is provided with a pedal pipe. A hook is fixed at the bottom of a last pedal rope sleeve. The device has the advantages of simple structure and convenient operation and can play the role of wire off backup protection, and convenience is brought to an operator to load and upload cross arms and conductive wires. The operation of the method is simple, the working efficiency is high, the disadvantages of multiple tools and complex operation in the past are avoided, and the device has a very high promotion value.

Description

technical field [0001] The invention relates to the technical field of special tools for power transmission lines, in particular to a multi-purpose backup device for preventing wires from falling off for power transmission lines. Background technique [0002] At present, when replacing composite linear insulator strings on power transmission lines, two sets of tools must be used, the upper cross-arm ladder and the backup protection rope to prevent the wire from falling off. There are many tools and complicated operations, which are not conducive to safe production. Currently, there is no elimination of such devices. Therefore, it is very important to develop a safe, convenient and applicable multi-purpose anti-lead fall-off backup device for transmission lines. Contents of the invention [0003] The object of the present invention is to provide a device for replacing a composite linear insulator on a power transmission line, specifically a multi-purpose backup device for ...
