Problems solved by technology

When a single piece in the insulator string has a zero value, it is necessary to replace the single piece. Due to the structural characteristics of the insulator string, the gap between the umbrella groups is very small. It is extremely inconvenient to use ordinary pin removal tools. The disassembly process is very difficult, which makes the maintenance work very difficult. In order to solve the disassembly problem of the R-type pin of the insulator in the running state, a special tool needs to be made

Embodiment Construction

[0014] The pin remover used for the R-type pin of the insulator of the present invention includes a sleeve 5, and the sleeve 5 is cylindrical with upper and lower openings. A duckbill 10 protrudes forward from the lower part of the sleeve 5, and the front end of the duckbill 10 is divided into upper and lower pieces, which are respectively an upper duckbill 9 and a lower duckbill 8; the front end of the upper duckbill 9 is a wide plate shape, the lower part is a groove shape matched with the top of the R-shaped pin; the front end of the lower duckbill 8 is a pointed column, which can be inserted into the R-shaped pin; the duckbill 10 of this structure can not only be inserted with the lower duckbill 8 The R-type pin stirs up the R-type pin, and it can also be pressed into the porcelain insulator by using the top of the upper duckbill 9 and the lower top of the R-type pin. A pair of ear handles 4 are relatively fixedly connected to both sides of the upper part of the sleeve 5, ...

Abstract

The invention discloses a pin remover for an R-shaped pin of an insulator. The pin recover comprises a sleeve 5; a duckbilled part 10 is arranged at the lower part of the sleeve 5; a pair of side handles 4 is oppositely fixedly connected to the upper part of the sleeve 5; an inner shaft 2 passes through the sleeve 5 and can move and rotate up and down in the sleeve; a pressing plate 1 is fixedly connected to the upper end of the inner shaft 2; the inner shaft between the pressing plate and the sleeve is sleeved with a spring 3. With the adoption of the pin remover, the working efficiency of overhauling of the insulator can be effectively improved, the operation of the R-shaped pin is greatly simplified, the overhaul time is reduced, and the working efficiency is improved. The pin remover is quick to be operated, convenient to carry, and flexible to use, can effectively improve the working efficiency and amplify the operation of workers in a tower and can also effectively overcome the actual difficulty at daily overhaul work.

Description

technical field [0001] The invention relates to a high-voltage line disassembly tool, in particular to a pin remover for R-shaped pins of insulators. Background technique [0002] In the high-voltage transmission line, the tension-resistant towers generally use porcelain insulators to connect the wires and towers to keep them insulated. The porcelain insulators are mostly connected by R-shaped pins. When a single piece in the insulator string has a zero value, it is necessary to replace the single piece. Due to the structural characteristics of the insulator string, the gap between the umbrella groups is very small. It is extremely inconvenient to use ordinary pin removal tools. The assembly and disassembly process is very difficult, which makes the maintenance work very difficult. In order to solve the assembly and disassembly problem of the R-type pin of the insulator under the running state, it is necessary to make a special tool. Contents of the invention [0003] The...
