Description

Insulator removal pin remover

technical field

The utility model relates to an electric device, namely an insulator dismantling and canceling device.

Background technique

Insulators are the main components of transmission line insulation, and insulators are mostly used in long strings of multiple insulators. A single insulator is mostly in the shape of an umbrella, with an umbrella cap, a side opening on one side of the umbrella cap, and a vertical hole in the middle of the umbrella cap. Stretch out, and the horizontal head is stuck under the vertical hole, and the hooking can be realized. In order to prevent the connecting rod from returning from the approach and coming out, the umbrella cap is inserted with an R-shaped pin under the cross head. When replacing the insulator, the R-shaped pin must be taken out at first, and then the connecting rod can be taken out, and then each insulator is disassembled. Since the R-shaped pin is relatively strong, a special tool must be used to pull it out. The tool currently used to pull out the R-shaped pin is a hook with a handle. After the hook is hooked into the R-shaped pin, the handle is pressed, and the R-shaped pin is pulled out using the principle of leverage. However, the lever stroke of this tool is very small, and it can only play a role in the initial stage of pin extraction. It is difficult to pull out the R-shaped pin completely, and people need to pull it hard, which is laborious, low in work efficiency, and often fails to pull out the pin. The phenomenon.

Contents of the invention

The purpose of the utility model is to provide an insulator dismantling and pin removal device which can completely pull out the R-shaped pin, which is relatively labor-saving and efficient.

The above-mentioned purpose is achieved by the following technical solutions: develop an insulator dismantling and pin removal device, which is characterized in that: there is an "n" shaped bracket, a through hole is opened in the middle of the bracket, and a lead screw passes through the through hole, and the lower end of the lead screw is There is a chuck with a notch, and there are jacks on both sides of the notch, a screw wrench is provided on the upper part of the screw above the bracket, and a stick is provided, and the stick slides and fits with the jacks on both sides of the notch of the card. When in use, the lower end of the bracket touches both sides of the R-shaped pin of the insulator, the R-shaped pin enters the notch of the clamp head of the lead screw, inserts the stick into the socket and the R-shaped pin, turns the screw wrench, and the screw goes up, and the R-shaped pin can be pulled out. pin.

Said spiral wrench is rod-shaped, and a screw nut matched with the leading screw is fixed in the middle.

Said plunger is fastened on the support by a soft stay cord.

Said support side has rope hole.

The beneficial effect of the utility model is that the R-shaped pin can be pulled out completely, and the utility model is relatively labor-saving, high in efficiency and close to 100% in success rate, and is expected to become an essential tool for line maintenance.

Detailed ways

The general design of the utility model is: the n-shaped support is used as a support, the leading screw in the middle of the support is articulated with the R-shaped pin, and the leading screw is screwed to pull out the R-shaped pin. A kind of embodiment is introduced below in conjunction with accompanying drawing.

What Fig. 1 introduces is an insulator dismantling pin remover, its main body is an "n" shaped bracket 1, combined with Fig. 2 and Fig. 3, it can be seen that there is a through hole 5 in the middle of the bracket 1. Pass a leading screw 2 in the through hole, as can be seen in conjunction with Fig. 4: leading screw 2 lower ends are provided with chuck 7, gap 8 is arranged in the middle of the lower segment of chuck 7, gap 8 both sides have jack 9. The upper section of the lead screw above the bracket is equipped with a screw wrench 3, as can be seen in conjunction with Fig. 5 and Fig. 6: the screw wrench 3 is rod-shaped, and a screw nut 10 matched with the lead screw 2 is fixed in the middle. Also can see by Fig. 1: support one side is equipped with a plunger 4 in addition, plunger 4 and the jack 9 on both sides of the chuck gap 8 of leading screw 2 slide fit. For ease of use, the stick 4 is tied to the support 1 through a soft pull cord 11 . Preferably as shown in Figure 2, there is a rope hole 6 on one side of the support 1, and the stay cord 11 is passed through the rope hole 6, and then knotted and connected to the support 1, so that it will not be lost.

During use, the lower end of the support is against the both sides of the R-shaped pin 13 of the insulator 12, and the half-ring head of the R-shaped pin 13 just enters the chuck gap 8 of the lead screw 2, and then inserts the stick 4 into the socket 6 and the R-shaped pin 13, Turn the screw wrench 3, the leading screw 2 can move upwards, and the R-shaped pin 13 is forcibly pulled out.
