Tension resistant four-serial string whole composite insulator replacing device

Abstract

The invention relates to a tension resistant four-serial string whole composite insulator replacing device which belongs to the technical field of power line maintaining tools. The invention aims to provide a tension resistant four-serial string whole composite insulator replacing device which has simple and portable structure, convenient and rapid operation and safe use. The tension resistant four-serial string whole composite insulator replacing device comprises a front end wing-shaped clamp, a rear end wing-shaped clamp, a screw rod, a pull plate and Y-joints, wherein the lower part in themiddle of the front end wing-shaped clamp is provided with a transverse clamping groove (11); both sides of the lower part of the clamping groove are provided with vertical screw holes (12); both wing ends of the front end wing-shaped clamp are respectively provided with a screw hole (13); the rear end wing-shaped clamp (6) is formed in such a way that two symmetrical assemblies are connected by a bolt; grooves (81) symmetrically arranged in the combining part of the two symmetrical assemblies are formed into a through hole (81); both wing ends of the rear end wing-shaped clamp are respectively provided with a screw hole (83); and the Y-joint (2A), the screw rod (3), the Y-joint (2B), the pull plate (5) and the Y-joint (2C) are sequentially connected between both wing ends of the front end wing-shaped clamp and the front end wing-shaped clamp.

Description

technical field [0001] The utility model relates to a tension-resistant quadruple-series insulator replacement device, which belongs to the technical field of power line maintenance tools. Background technique [0002] With the development of power grid technology, the application of large cross-section and large-capacity wires on ultra-high voltage lines is becoming more and more popular. The use of large cross-section wires has given birth to the generation of strain-resistant quadruple insulator strings. Due to the high anti-fouling flashover ability of composite insulators, it is gradually popularized from linear string applications to tension string applications. However, due to the large horizontal tension of tension-resistant quadruple series composite insulators, it is very difficult to replace the entire string of insulators. Usually, a relatively bulky chain hoist is used, and the whole string is tightened by a wire rope and a wire clamp, and the whole string is re...
