Multifunctional suspension insulator string cross arm side hardware fitting replacement fixture

Abstract

The invention discloses a suspension insulator string cross arm side hardware fitting replacement fixture, which comprises a cross arm side fixture, a lead side fixture and a frapping device. The cross arm side fixture comprises a first fixture and a second fixture. When the fixture is used, the first and second fixtures can be freely selectively arranged in a required way according to the form of a cross arm end. When fixing holes on the upright sides of T-shaped structures of the first and second fixtures connect the first and second fixtures by utilizing connecting parts, a relative distance between the two fixtures can be regulated according to the needs of the cross arm end. Simultaneously, a position at which the arrangement of the frapping device is required can be regulated by utilizing through holes on one transverse side of each of the T-shaped structures of the first and second fixtures to enable cross arms with different widths to enter the frapping device for fit with an insulator socket fixture. The lower part of each of the first and second fixtures has a ladder-like structure so as to be adaptively arranged on a planar tower material and clamped to angle iron and the like.

Description

technical field [0001] The invention relates to a jig for replacing a suspension insulator string, in particular to a multifunctional jig for replacing a metal fitting on the cross-arm side of a suspension insulator string. [0002] Background technique [0003] Since the high-voltage transmission line is exposed to the outdoor environment for a long time, it is subjected to the effects of wind, rain, impurities in the air, and alternating cold and heat, which may easily cause wear, rust, corrosion and other defects in the metal fittings. The traditional method of replacing the "hanging insulator string cross-arm side fittings" is: the personnel on the pole use a wire tightener to tighten the wires to loosen the insulator strings, and then the ground personnel cooperate to lift the insulator strings, and then carry out the cross-arm side fittings. replacement. However, due to the 35-220kV line straight pole tower and tension pole tower jumper suspension insu...

AI Technical Summary

Problems solved by technology

However, due to the 35-220kV line line tower, the tension tower jumper wire suspension insulator strings are mostly located in places with complex terrain, complex pole shapes, and high towers.

Therefore such operating tools and operating methods are not only time-consuming and laborious, but also cumbersome.

Although people have successively developed some fixtures for replacing the cross-arm side fittings of suspension insulator strings, these fixtures are often only developed for the cross-arm head of a specific assembly method, so the application range is too narrow and the versatility is poor. As a result, a maintenance point needs to be equipped with multiple sets of clamps to adapt to various cross-arm heads, which brings great inconvenience to use and storage
