Insulator replacement device

Abstract

The invention provides an insulator replacement device. Through additionally arranging a rope winding column, a fixed pulley No.3, a fixed pulley No.2, a fixed pulley No.1 and a lifting hook, when theinsulator replacement device is actually used for replacing an insulator, an electrician prejudges heights of different types of insulators, a rope body at the bottom end of a lifting and lifting rope is wound to reserve a length, the length of the lifting and lifting rope can be adjusted according to different needs, the additionally arranged lifting and lifting rope and an elastic compression spring can plug an opening at all times when the insulator is lifted, thereby avoiding the fall-off and damage phenomena caused by operations of shaking and the like.

Description

technical field [0001] The present invention relates to the field of electric equipment tools, and more specifically, relates to an insulator replacer. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with many disc-shaped insulators hanging on one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not play a significant role and will impair the service and operating life of the entire line. [0003] However, the replacement of existing insulators needs to call railway engineering vehicles, which needs to be scheduled by the plannin...

Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulator will not have a significant effect and will damage the service and operating life of the entire line

[0003] However, the replacement of existing insulators needs to call railway engineering vehicles, which needs to be scheduled by the planning department and opened up special time and lines. The time is long and the cost is high. The response speed to emergencies is too slow. If it is an emergency, the whole process can only be suspended first. The operation of this line will cause huge losses to people’s production and life. Although some insulator replacers are designed, the insulator replacement efficiency is low, and it is difficult to adapt to the different height requirements of different types of insulators. In addition, the traditional fixed clamp form The adaptability is also not good, and the free adjustment of the angle position cannot be realized, and the practicability is not high, which affects the actual use
