Abstract

A special tool for pulling and inserting an R type spring pin from an insulator is disclosed. The special tool for pulling and inserting the R type spring pin from the insulator is characterized by comprising a pressure handle, a labor-saving rod, a fixed groove and an opening hook, wherein the labor-saving rod and the pressure handle are perpendicularly connected; the upper part of the opening hook is perpendicularly connected with the labor-saving rod; the fixed groove is formed in the middle of the opening hook; and the lower part of the opening hook is in a trapezoidal opening structure. The special tool for pulling and inserting the R type spring pin from the insulator has the advantages that the R type spring pin can be rapidly pulled out and inserted by only two simple steps, and the R type spring spin and the insulator body are not damaged by the special tool; and in addition, the operation time is saved, the working efficiency is improved, and the potential safety hazard on operators caused by fatigued operations is eliminated.

Description

technical field [0001] The invention relates to a working tool for an electric power system, in particular to a special tool for pulling and inserting R-shaped spring pins of insulators. Background technique [0002] After a period of operation, the insulation and mechanical properties of 66-500 kV transmission line insulators may deteriorate or be damaged to a certain extent. In order to ensure the normal operation of the line and avoid tripping accidents caused by the reduction of insulation level, regular Replace unqualified insulators. Most of the insulators used in the current 66-500 kV transmission lines are connected by R-type spring pins. The following methods are usually used to replace this type of insulator: 1. Use 200mm pliers to clamp the exposed part of the tail of the R-shaped spring pin and pull it out forcefully, so that the insulator has enough clearance to withdraw from the connection and replace it. 2. Use the tail of the adjustable wrench to tap the bi...
