A replacement tool for tension insulator strings

Abstract

The invention discloses a replacement tool for tension insulator strings, which comprises two insulating ropes arranged in parallel. The front and rear ends of the insulating ropes are respectively connected to a front card and a rear card. The bar is connected to the front end of the insulating rope, the left and right ends of the rear card are connected to the rear end of the insulating rope, and a middle card is arranged in front of the rear card between the two insulating ropes, and a tightening wire is respectively provided at the left and right ends of the middle card. The bar is connected to the rear card, and the sides of the front card and the rear card are also connected to the side connection plate through the middle plate, and the side connection plate is connected to the tension insulator. The present invention uses three types of fixtures as the main body, the front clamp, the middle clamp and the rear clamp, together with a high-strength insulating rope and a front tightening lead screw, so as to realize the transfer of the tension of the wire, loosen the string of insulators, and achieve the replacement of insulators and the adjustment of sag , The purpose of dealing with wire defects.

Description

[0001] The patent application for this invention is a divisional application for an invention patent titled "A Special Tool for Lively Replaced Tension Insulator Strings". The original application date was September 5, 2013, and the application number was 201310399062X. technical field [0002] The invention relates to a special tool for replacing strain insulator strings. Background technique [0003] For the conventional method of replacing strain string insulator strings on 500kV lines, the wires are first tightened with mechanical screw rods or hydraulically tightened hard insulating rods, and then the insulator strings are lifted by insulating bottle racks or hanging bottle hooks to make the insulator strings look like Relaxed state, and then break away from the metal connection between the insulator string and the wire, to achieve the purpose of replacing insulators, adjusting sag, and dealing with wire defects. [0004] But there is following defective in prior art: ...

AI Technical Summary

Problems solved by technology

[0005] 1. The hard insulating poles and bottle holders are bulky and heavy, and the carrying and handling are limited. The difficulty and labor intensity of high-altitude operations for live workers on the tower are very high

[0006] 2. The length is fixed, the versatility is poor, and it is necessary to manufacture tools and appliances with various specifications
