The invention relates to an anti-pollution pin pulling device belonging to a special instrument for pulling out a spring pin in power operation maintenance. The anti-pollution pin pulling device comprises a pair of pin pulling pliers and is also provided with a left supporting seat and a right supporting seat, wherein the right supporting seat is formed by welding a lug plate on a pipe joint; a left handle and a right handle of the pin pulling pliers are respectively in a 'Z' curved shape; the left handle of the pin pulling pliers is fixed with the lug plate of the left supporting seat; the right handle of the pin pulling pliers is fixed with the lug plate of the right supporting seat; a tension spring is fixedly connected between the lug plate of the left supporting seat and the lug plate of the right supporting seat; a connecting pipe for connecting an insulating tool is movably inserted into two pipe joints of the left supporting seat and the right supporting seat; threads and seams are arranged on two outer ends of the connecting pipe extending out of the pipe joints; two compression screws are symmetrically screwed on the connecting pipe from left to right; and the two compression screws are in compression joint on two strip-shaped notches on the two pipe joints of the left supporting seat and the right supporting seat. The invention has the characteristics of reliable performance, convenient use and wide universality and is suitable for hot-line installation and disassembly of spring pins of anti-pollution insulators and common insulators in power industry.
Description
technical field [0001] The invention relates to a pliers tool, in particular to a special tool for pulling out spring pins for live work in electrical maintenance. Background technique [0002] When ordinary pin pulling pliers are performing live pin pulling operations, since the ball head of the anti-pollution insulator is deeply buried in the magnetic skirt of the insulator, the skirt of the insulator blocks the entry of the general pin pulling pliers. Homework, the operation of pulling out pins has brought great difficulty. Simultaneously, the clamping force of the existing pin pulling pliers to the spring pin of the insulator depends entirely on the grip strength of the human hand, so there are disadvantages that the clamping force is small and the clamping is difficult to be stable and durable. Contents of the invention [0003] The object of the present invention is to provide an anti-pollution pin puller with stable clamping, reliable performance and convenient use...
