A kind of opening and closing fixture for bearing insulator

Abstract

An openable and closed clamp for carrying insulators, including clamp limit rods. There are two clamp limit rods, which are respectively screwed into the two sides of an open and close clamp assembly. After the open-close clamp assembly is opened, place the insulator to be assembled in the middle of the open-close clamp assembly, then close and lock the open-close clamp assembly, buckle the insulator to prevent the insulator from coming out, and then close the clamp The positioning rods are respectively screwed into the two sides of the open-close clamp assembly to position the open-close clamp assembly and the insulator. The overall bearing capacity of the present invention can reach 40-60 tons, which can meet the requirements of the existing insulator strings with a maximum tonnage of 55 tons; the present invention only needs to use a longer clamp limit rod to meet various tightening and loosening requirements. The adjustable distance requires a larger adjustable distance range; and the invention has a simple structure, low cost, can be matched with existing insulator structures, and has good versatility. The invention is applicable to the bearing field of insulators of various large tonnages.

Description

technical field [0001] The invention relates to a load-carrying device, in particular to a closed fixture for carrying the weight of a large-tonnage insulator. Background technique [0002] At present, emergency maintenance and daily maintenance departments of power systems often deal with insulators, which are usually made of glass or ceramics. The two functions must be guaranteed. The insulator should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not function, and the service life and operating life of the entire line will be damaged. [0003] In power transmission and transformation systems, insulators are usually made into insulator strings, which leads to a sharp increase in the weight and tonnage of the insulators. The weight of the heaviest insulator strings in the existing technology can reach 55 tons, so the tools for carrying insulators must have high load bearing...

Problems solved by technology

[0008] In order to solve the defects of low load-bearing force and structural design problems in the old clamps for carrying insulators in the prior art, which lead to a small range of adjustable distances, the present invention provides an open-close clamp for carrying insulators , through the redesigned clamp structure, it has obtained a larger tonnage bearing capacity than the old clamp, and the adjustable range has also expanded accordingly. An open-close clamp for carrying insulators according to the present invention, its The specific structure is as follows:
