Problems solved by technology

In the past, a small-diameter punch was often used to punch out the inner pin at the maintenance site, and then a punch with a diameter matching the outer layer pin was used to punch out the outer pin. Frequently changing tools in the middle made the operation process long and difficult for maintenance. Reduced efficiency

Embodiment Construction

[0010] Such as figure 1 Shown: a special tool for removing elastic pins in double-layer sets of isolating switches, including a handle 1 and a punch 4, and the punch 4 is connected to the handle 1.

[0011] The punch 4 includes an inner pin punch 3 and an outer pin punch 2, and the inner pin punch 3 and the outer pin punch 2 are connected.

[0012] Both the inner pin punch 3 and the outer pin punch 2 are cylinders.

[0013] Because the diameter of the inner pin punch 3 is consistent with the diameter of the inner layer pin, the inner pin punch 3 can enter the inside of the outer pin, the diameter of the outer pin punch 2 is consistent with the diameter of the outer pin, and the outer pin punch 2 can enter the round hole of the workpiece. Therefore, the present invention uses , the internal pin punch 3 is in contact with the internal pin of the isolating switch double-layered elastic pin. Under the hammering of the hammering tool, the internal pin punch 3 punches out the inter...

Abstract

The invention discloses a tool special for detaching an isolating switch double-layer sleeved elastic pin. The tool comprises a handle and a punch, wherein the punch is connected with the handle; the punch comprises an inner pin punch and an outer pin punch; the inner pin punch is connected with the outer pin punch; and both the inner pin punch and the outer pin punch are cylinders. During use, the inner pin punch is contacted with an inner pin of the isolating switch double-layer sleeved elastic pin, the inner pin punch makes the inner pin rush out under the hammering of a hammering tool, the tool is not needed to be replaced, the outer pin punch is contacted with an outer pin of the isolating switch double-layer sleeved elastic pin, and two layers of inner and outer pins rush out at one time by the hammering tool. The tool is convenient to use and reasonable in structure, avoids the inconvenience brought by the conventional detachment through two punches, reduces frequent tool replacement of the maintenance personnel, and improves the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of auxiliary tools for maintenance of electrical equipment, and in particular relates to a special tool for removing elastic pins with double-layer sets of isolating switches. Background technique [0002] GW16 and 17 type isolating switches are widely used in large substations. During the maintenance process, a large number of double-layered elastic pins need to be removed, and then the conductive part of the isolating switch can be disassembled. In the past, a small-diameter punch was often used to punch out the inner pin at the maintenance site, and then a punch with a diameter matching the outer layer pin was used to punch out the outer pin. Frequently changing tools in the middle made the operation process long and difficult for maintenance. Reduced efficiency. Contents of the invention [0003] The object of the present invention is to avoid the disadvantages of the above-mentioned prior art, and to...
