Replacing method of strain-resistant single-hole plate insulator string

Abstract

The invention relates to a clamping device and a method for replacing a single-hole connecting plate strain insulator string. The clamping device comprises a front bending plate clamp, a rear bending plate clamp, two adjustable aluminum alloy hanging rings and an aluminum alloy insulator cradle, wherein the upper part of the front bending plate clamp is used for being connected with a lead-side connecting plate, a steering pulley is fixed in the middle of the front bending plate clamp, and the lower part of the front bending plate clamp is connected with one of the adjustable aluminum alloy hanging rings; a rope which is connected with the front end of the aluminum alloy insulator cradle penetrates by virtue of the steering pulley; the upper part of the rear bending plate clamp is used for being connected with a cross arm-side connecting plate, the middle of the rear bending plate clamp is movably connected with the rear end of the aluminum alloy insulator cradle, and the lower part of the rear bending plate clamp is connected with the other adjustable aluminum alloy hanging ring; a plurality of holes for adjusting the connection position of the corresponding bending plate clamp are formed in each adjustable aluminum alloy hanging ring; the two adjustable aluminum alloy hanging rings are connected with double hooks. The clamp has the advantages of convenience in assembly and disassembly, high operability and the like; the labor intensity is reduced, safety requirements for overhead field operation are met, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to a jig for replacing insulator strings, in particular to a jig for replacing insulator strings with a tension-resistant single-hole joint plate and a replacement method. Background technique [0002] In recent years, due to the accelerated pace of power grid construction and the improvement of the operation and maintenance level of overhead lines, the types of boards running on overhead lines are different. However, the measures taken to replace the tension insulators of various types of connecting plates are also quite different. At present, the main method of replacing tension double-string insulators on overhead lines is to use wire clamps and chain hoists. This method is relatively expensive in terms of time, technology, and safety for replacing L-3050G* type tension single-hole insulator strings. There are many shortcomings. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of ...
