Abstract
A special tool for pulling and inserting an R type spring pin from an insulator is disclosed. The special tool for pulling and inserting the R type spring pin from the insulator is characterized by comprising a pressure handle, a labor-saving rod, a fixed groove and an opening hook, wherein the labor-saving rod and the pressure handle are perpendicularly connected; the upper part of the opening hook is perpendicularly connected with the labor-saving rod; the fixed groove is formed in the middle of the opening hook; and the lower part of the opening hook is in a trapezoidal opening structure. The special tool for pulling and inserting the R type spring pin from the insulator has the advantages that the R type spring pin can be rapidly pulled out and inserted by only two simple steps, and the R type spring spin and the insulator body are not damaged by the special tool; and in addition, the operation time is saved, the working efficiency is improved, and the potential safety hazard on operators caused by fatigued operations is eliminated.
Description
Technical field
The present invention relates to electric power system power tool, particularly a kind of insulator R type spring pin plug specific purpose tool.
Background technology
All likely there is deterioration to a certain degree or damage in 66-500 KV transmission line insulator its insulation property and mechanical performance after operation after a while, avoiding occurring to reduce because of insulation level the trip accident caused to ensure that circuit normally runs, should regularly change underproof insulator.The insulator that existing 66-500 KV transmission line uses adopts R type spring pin to connect mostly.Usually following methods can be adopted to carry out operation at replacing this type insulator: 1, to use the pliers of 200mm to clamp R type spring pin afterbody exposed portion and firmly extract, make insulator have enough gaps to exit and connect and change.2, using Adjustable spanner afterbody to knock R type spring pin crotch in insulator steel cap opening makes R type spring pin exit, and then changes insulator.Use above-mentioned two kinds of method operating personnel complex operations, efforts, easily produce fatigue, operating efficiency is low, may cause damage in various degree to R type spring pin and insulator simultaneously.
Summary of the invention
The object of the invention is to raise labour efficiency, save manpower, avoid causing damage to R type spring pin and insulator itself, spy provides a kind of insulator R type spring pin plug specific purpose tool simultaneously.
The invention provides a kind of insulator R type spring pin plug specific purpose tool, it is characterized in that: described insulator R type spring pin plug specific purpose tool, comprises pressure handle 1, laborsaving bar 2, holddown groove 3, opening hook 4;
Wherein: laborsaving bar 2 is connected with pressure handle 1 is vertical; The top of opening hook 4 is connected with laborsaving bar 2 is vertical, and middle part is with holddown groove 3, and the bottom of opening hook 4 is trapezoid-shaped openings structure.
The trapezoid-shaped openings structure of described opening hook 4 bottom, length ratio that trapezoid-shaped openings is gone to the bottom is 0.5 ~ 0.8.
Described pressure handle 1 is disc-shaped structure.
Described laborsaving bar 2 is hollow bar structure.
Described holddown groove 3 is borehole structure.
Hook R type spring pin afterbody exposed portion with opening hook 4, extrude R type spring pin by lever principle; After operating personnel more finishes changing new insulator, use the holddown groove 3 above opening hook 4 to withstand the afterbody of R type spring pin, then bounce pressure handle 1, R type spring pin is entered in insulator steel cap gap fast.
Advantage of the present invention:
Insulator R type spring pin plug specific purpose tool of the present invention, only needs two step simple operationss R type spring pin can be extracted and insertion fast, can not cause damage to R type spring pin and insulator itself.Save the activity duration, improve operating efficiency, eliminate the personal safety hidden danger because tired operation may bring.
