Problems solved by technology

[0002] When using ordinary tools to exchange linear insulator strings with electrified ground potential, it is often limited by the orientation of the insulator pins. If the pins are oriented to the side, the existing tools cannot be used to push and pull the pins, which brings great trouble to the field work.

Embodiment Construction

[0011] Such as figure 1 As shown, the present invention includes an insulating rod 1, and the front end of the insulating rod 1 is a depinning head 4, and the above-mentioned depinning head 4 can be a W pin depinning head and an R pin depinning head, wherein, the W pin depinning head and the R pin depinning head The device head is the cancel device head in the invention patent application with the application number 200910034511.4 and the invention name is "Live-line work cancel device".

[0012] In the present invention, a through hole 5 is arranged in the axial direction of the insulating rod 1, and the through hole 5 leads out to the direction of the pin removal head 4 at the upper end; The lower end of the insulating rod is correspondingly provided with a handshake 6. The above-mentioned flexible shaft 3 is closely composed of steel wire and spring, which not only has good strength, but also has good flexibility, can be bent, and is convenient to pass out from the directi...

Abstract

A live working pin removal device comprises an insulating rod. A pin removal head is arranged at the front end of the insulating rod, a through hole is axially arranged in the insulating rod, the upper end of the through hole extends outwards the direction of the pin removal head, a push rod is arranged in the through hole, and a flexible shaft is fixed at the upper end of the push rod. By the aid of the technical scheme, when a handgrip is held, the flexible shaft extends out of an insulating rod body to serve as a support point, the direction of the flexible shaft can be peripherally turned, and a pin is conveniently removed.

Description

technical field [0001] The invention relates to a live maintenance tool for power supply equipment, in particular to a 35KV-220KV live work canceler for on-site maintenance. Background technique [0002] When using ordinary tools to exchange linear insulator strings with charged ground potential, it is often limited by the orientation of the insulator pins. If the pins are oriented to the side, the existing tools cannot be used for pushing and pulling pins, which brings great trouble to the field work. So be badly in need of developing a kind of insulator pin and all can work when the insulator pin is towards four directions, push and pull the live work pin device to solve the difficult problem of maintenance. Contents of the invention [0003] The object of the present invention is to provide a live work canceler which facilitates canceling and improves working efficiency. [0004] To achieve the above object, the present invention adopts the following technical solution...
