Multifunctional insulated insulator cradle with adjustable length

Abstract

A multifunctional insulated insulator cradle with an adjustable length is characterized by comprising a wire end clamp, a hanging piece, a main insulator cradle body, an adjustable insulator cradle body and a threaded connection rod, wherein the hanging piece is fixedly connected to the right end of the main insulator cradle body and the wire end clamp is connected with the hanging piece; the right end of the adjustable insulator cradle body is inserted into the left end of the main insulator cradle body, the insertion thickness is adjustable, and the right end of the adjustable insulator cradle body is positioned through a through hole and a pin on the adjustable insulator cradle body; the left end of the adjustable insulator cradle body is connected with the threaded connection rod. The multifunctional insulated insulator cradle with the adjustable length has the advantages that the length is adjustable, the multifunctional insulated insulator cradle can satisfy the requirement for replacement of insulator chains with insulator sheets in different numbers and can replace a plurality of original insulator cradles of different lengths, the management and storage difficulty of insulation tools is lowered, the multifunctional insulated insulator cradle is detachable and is easy to assemble, vehicle transportation and manual carrying are facilitated, an end fixing and hanging device is additionally arranged so that the multifunctional insulated insulator cradle can be converted into an insulated horizontal ladder, and therefore an operator can enter a highfield and exit from the highfield.

Description

technical field [0001] The invention relates to the field of live working tools for high-voltage transmission lines, in particular to a multifunctional length-adjustable insulating bottle holder. Background technique [0002] At present, due to different factors such as the environment of the transmission line, the insulation configuration of the tension insulator string of the 220 kV transmission line is inconsistent, that is, the number of pieces of the tension insulator string varies from 15 pieces to 19 pieces. When these insulators are damaged or deteriorated, the insulation level of the whole string of insulators will be greatly reduced, seriously affecting the safe operation of transmission lines. Therefore, it must be replaced in time. The replacement of insulators can be carried out in two different ways: blackout work or live work. At present, due to the consideration of the reliability of power supply, the method of live work replacement is often used. When rep...

AI Technical Summary

Problems solved by technology

[0003] In order to realize the replacement of insulator strings with different numbers of insulators, the operating unit has to purchase insulating bottle holders of different lengths, resulting in waste of tool purchase funds and increased difficulty in keeping and storing insulating tools

In addition, when preparing tools before live work, since the length difference of different bottle holders is 146mm×n (n is the number of insulators), the difference is not very big, and it is easy to mistakenly take the bottle holder that is inconsistent with the length of the actual insulator string on site , causing the job to fail
