Tool of replenishing cotter pin in transmission line in electrifying manner

Abstract

The invention discloses a tool of replenishing a cotter pin in a transmission line in an electrifying manner. The tool is used for solving the difficulty of incapability of replenishing the cotter pin in an electrifying manner due to limit of the tower type and the space distance. The tool comprises a pin replenishing device and an insulation operation rod, wherein the pin replenishing device is arranged on the top end of the insulation operation rod, the pin replenishing device comprises a cotter pin gesture regulating mechanism, a cotter pin location mechanism and an installing base, the cotter pin gesture regulating mechanism comprises a dumbbell-shaped connecting shaft and two cylinder hollow bases which are symmetrically arranged leftwards and rightwards, sphere bodies of two ends of the dumbbell-shaped connecting shaft are respectively assembled with the two cylinder hollow bases, long grooves communicated with the inner end faces of the two cylinder hollow bases are arranged in the outer walls of the two cylinder hollow bases, and locking bolt assemblies are arranged on the outer walls of the cylinder hollow bases. The tool has the advantages of simple structure, convenience for operation, capability of realizing long-distance cotter pin replenishing operation under the condition that a transmission line is uninterrupted, and achieves a satisfactory effect on the aspects of safety, economy and working efficiency.

Description

technical field [0001] The invention relates to a special tool suitable for refitting a missing cotter pin on a power transmission line, which belongs to the technical field of power distribution. Background technique [0002] Checking the integrity of each component is a very important task in transmission line maintenance. Especially in the connecting parts of various power components, the cotter pins used to prevent the nuts from loosening on the connecting bolts will easily corrode, break and fall off due to atmospheric corrosion after working for a period of time, which brings great difficulties to the safe operation of the transmission line. Therefore, the missing cotter pins must be replaced in time. At present, when refitting the cotter pin, due to the limitation of the form of the tower and the space distance, two methods of power outage treatment and equipotential operation are generally used, which cannot achieve satisfactory results in terms of safety, economy a...

Problems solved by technology

Especially in the connecting parts of various power components, the cotter pins used to prevent the nuts from loosening on the connecting bolts will easily corrode, break and fall off due to atmospheric corrosion after working for a period of time, which brings great difficulties to the safe operation of the transmission line. A big hidden danger, therefore, the missing cotter pin must be replaced in time

At present, when refitting the cotter pin, due to the limitation of the form of the tower and the space distance, two methods of power failure treatment and equipotential operation are generally used, which cannot achieve satisfactory results in terms of safety, economy and work efficiency.
