Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 2 As shown, the pin puller applied to the R pin of the insulator is composed of four parts, including the handle part 1, the connecting rod 2, the first cylinder 3 and the second cylinder 4, and the first cylinder 3 and the second cylinder 4 The operating part is formed parallel to each other, the handle part 1 is connected with one end of the connecting rod 2, the other end of the connecting rod 2 is connected with the operating part, and the first cylinder 3 and the second cylinder 4 are connected with the connecting rod 2.

[0028] The hand-held part 1 is a flat structure, and the flat-plate structure is provided with a round hole 5; the round hole 5 is provided with the convenience of carrying, and can be hung on the hook of the worker's safety belt, and the hand-held part 1 is made of thicker flat iron, which can be lifted t...

Abstract

The invention discloses a pin puller applied to an insulator R pin. The pin puller comprises a handheld part, wherein the handheld part is connected with one end of a connecting rod; the other end of the connecting rod is connected with an operation part; the operation part comprises parallel first column body and second column body; the first column body and the second column body are connected with the connecting rod; and the first column body and the second column body are vertical to the other end of the connecting rod. Through arrangement of the first column body, the second column body, the connecting rod and the handheld part, a lever structure is formed; a pin is pulled by the lever principle; and the problems that original pin pulling nippers are difficult to clamp when the pin is pulled and time and energy are wasted are solved. The connecting rod of the pin puller is arranged into an arc-shaped J-type structure, the force provided to the first column body is just used for pulling the R pin outwards; and meanwhile, greater force can be provided to the first column body to pull the R pin.

Description

technical field [0001] The invention belongs to the technical field of power transmission line maintenance operations, and relates to a pin puller applied to the R pin of an insulator, in particular to a device for removing the R pin in the bowl head of an insulator. Background technique [0002] The connection part of the transmission line insulator usually uses the R pin. When removing the R pin 7 in the insulator bowl head 9, as figure 1 As shown, because the round mouth 8 of the R pin 7 is relatively small, the diameter of the jaws of the traditional pin puller 6 is larger than the diameter of the round mouth 8 of the R pin 7, so it is difficult to stretch it into the R pin 7 to clamp it , can only clamp the outside, and the outside of the R pin 7 is smooth, and it is easy to slip off after being clamped by the traditional pin puller 6; in addition, because the R pin 7 is a steel structure, after clamping the outside of the R pin 7, it must be A lot of force can be used...
