After a period of operation, the insulation and mechanical properties of 66-500 kV transmission line insulators may deteriorate or be damaged to a certain extent. In order to ensure the normal operation of the line and avoid tripping accidents caused by the reduction of insulation level, regular Replace unqualified insulators. Most of the insulators used in the current 66-500 kV transmission lines are connected by R-type spring pins. The following methods are usually used to replace this type of insulator: 1. Use 200mm pliers to clamp the exposed part of the tail of the R-shaped spring pin and pull it out forcefully, so that the insulator has enough clearance to withdraw from the connection and replace it. 2. Use the tail of the adjustable wrench to tap the bifurcation of the R-shaped spring pin in the opening of the insulator steel cap to make the R-shaped spring pin withdraw, and then replace the insulator. Using the above two methods is cumbersome and laborious for operators, prone to fatigue, low work efficiency, and may cause varying degrees of damage to the R-shaped spring pins and insulators.

Utility model content

The purpose of the utility model is to improve labor efficiency, save manpower, and at the same time avoid damage to the R-shaped spring pin and the insulator itself, and specially provides a special tool for pulling and inserting the R-type spring pin of the insulator.

The utility model provides a special tool for pulling and inserting an insulator R-shaped spring pin, which is characterized in that: the special tool for pulling and inserting an insulator R-shaped spring pin includes a pressure handle 1, a labor-saving rod 2, a fixing groove 3, an opening hook 4;

Wherein: the labor-saving rod 2 is vertically connected with the pressure handle 1; the upper part of the opening hook 4 is vertically connected with the labor-saving rod 2, the middle part has a fixing groove 3, and the lower part of the opening hook 4 is a trapezoidal opening structure.

In the trapezoidal opening structure at the lower part of the opening hook 4, the ratio of the lengths of the upper and lower bottoms of the trapezoidal opening is 0.5-0.8.

The pressure handle 1 is a disc-shaped structure.

The labor-saving rod 2 is a hollow rod structure.

The fixing groove 3 is a circular hole structure.

Use the open hook 4 to hook the exposed part of the tail of the R-shaped spring pin, and press out the R-shaped spring pin through the principle of leverage; after the operator replaces the new insulator, use the fixed groove 3 above the open hook 4 to withstand the R-shaped spring pin Then tap the pressure handle 1 to make the R-shaped spring pin quickly enter the gap of the steel cap of the insulator.

Advantage of the utility model:

The special tool for plugging and unplugging the R-type spring pin of the insulator described in the utility model can quickly pull out and insert the R-type spring pin with only two simple operations, and will not cause damage to the R-type spring pin and the insulator itself. damage. It saves working time, improves work efficiency, and eliminates potential personal safety hazards that may be caused by fatigue work.
