Abstract

The invention provides an adaptive closed fixture for a live working insulator of a power transmission line. The adaptive closed fixture mainly comprises a front clamping body, a rear clamping body, a front clamping cover and a rear clamping cover, wherein the front clamping body and the rear clamping body are applied to front and rear steel caps of the insulator respectively; the front clamping cover and the rear clamping cover are matched with the front clamping body and the rear clamping body respectively; the front clamping body and the front clamping cover, and the rear clamping body and the rear clamping cover are connected together through pin shafts at one end respectively; semi-arc grooves with the same radius are formed between the front clamping body and the front clamping cover, and between the rear clamping body and the rear clamping cover respectively; a round bayonet capable of clamping the steel caps of the insulator is formed in the middle when the front clamping body and the front clamping cover, and the rear clamping body and the rear clamping cover are hinged into a whole respectively; the other ends of the front clamping body and the front clamping cover, and the rear clamping body and the rear clamping cover are connected with clamping bolts with fixing nuts through the pin shafts respectively; and in the round bayonet in the middle of the front clamping body, the front clamping cover, the rear clamping body and the rear clamping cover, a large inclined plane is arranged at least from one side surface to the other side surface and a large reducing tapered bayonet is formed.

Description

technical field

[0001] The invention relates to a self-adaptive closed clamp for live working insulators of transmission lines, which is used for replacing insulators of different manufacturers and types on high-voltage transmission lines, and belongs to the technical field of maintenance tools for overhead transmission lines. Background technique

[0002] When replacing the insulator on the transmission line, it is necessary to prepare corresponding tools according to different manufacturers and different types of insulators. When the tools and tools carried do not match the specifications and sizes of the replaced insulators, the replacement operation will not be possible and other specifications need to be replaced. The size of tools and utensils puts forward higher requirements for the preparatory work of the operation. At the same time, when the size of the portable tools and utensils does not match, it needs to be replaced in time, and the work is time-consuming and lab...
