Abstract

An anti-falling convenient pin remover comprises a connecting rod, the top of which is connected with one end of a U-shaped connecting rod; the other end of the U-shaped connecting rod is of a conical structure; an insulated bushing is sleeved at the middle part of the connecting rod and an anti-falling ring is fixed at one side of the connecting rod. The end of the pin recover is of a conical structure and can be easily inserted in a single insulator; when the single insulator is replaced and the pin is assembled / disassembled, the anti-falling convenient pin remover solves problems of increasing operator's working strength and working time, resulting from multiple repeated operations caused by operator's low success rate of assembling / disassembling the insulator pin at the first time. The anti-falling ring is arranged at one side of the anti-falling convenient pin remover, so that a rope can be conveniently twisted on the anti-falling ring and the falling of the anti-falling ring caused by the drop of the rope is avoided. The anti-falling convenient pin remover has the advantages of simple and compact structure, low manufacturing cost and convenience in use.

Description

technical field [0001] The invention relates to a pin remover, in particular to a drop-proof and convenient pin remover. Background technique [0002] In the process of replacing the single-piece insulator and installing the pin, the end of the pin remover is blunt and has a large end area, so it is not easy to insert the end of the pin remover into the single-piece insulator. Low cost, repeated operations are required, which increases the working intensity and working time of personnel; the traditional decanter has no anti-fall device, and the decanter is easy to drop from a high altitude, which poses a great hidden danger to the safety of operators. The anti-falling measure of the traditional depinner is just to tie the rope to the depinner, and the operation time is long, and the rope is easy to fall off. Contents of the invention [0003] The purpose of the present invention is to provide a remote control gliding device for live work, which can solve the problems of l...
