Abstract

The invention discloses a fixture for installing spring band which comprises an annular bracket, wherein multiple cylinders are evenly arranged on the outer wall of the annular bracket along the circumferential direction of the bracket, each cylinder comprises a piston rod which stretches out and draws back along the radial direction of the bracket and extends to the inner side of the bracket, a claw piece which is used for hooking the inner circle of the spring band and applying radial outward tension is fixed on the tail end of the piston rod of each cylinder, which is arranged at the inner side of the bracket, and the cylinder body of each cylinder is communicated with an air source through an air channel connecting pipe. The claw pieces can be driven to move outwards along the radial direction of the bracket by the piston rods and the spring band is driven to expand outwards by the claw pieces, thus the expansion of the spring band can be easily realized, the operation is simple and the assembly efficiency is high.

Description

technical field

[0001] The invention relates to a tool for installing a spring hoop on a petal-shaped contact finger of a million-volt GIS product. Background technique

[0002] The petal-shaped contact finger assembly is a part used for conducting electricity in the movable part of the high-voltage circuit breaker product. It consists of 30 contact fingers evenly distributed on the outside of the cylinder, and two spring hoops are used on the outside of the contact fingers to make good contact between the contact fingers and the cylinder. . The traditional assembly is to use manpower to open the spring hoop and put it on the contact finger. Due to the large contraction force of the spring hoop, the assembly is very inconvenient. Contents of the invention

[0003] The purpose of the present invention is to provide a spring hoop installation tool that can easily stretch the spring hoop, has simple operation and high assembly efficiency.

[0004] The present invention adop...
