Description

Anti-drop device for working at heights

technical field

The utility model relates to the technical field of electric power maintenance equipment, in particular to an anti-falling device for working at heights.

Background technique

Now whether it is central or local, safety production is placed at the top of every management. As a power company of the State Grid Corporation of China, it puts safety production at the top of all management tasks, and puts personal safety in the first place, which cannot be touched as a red line. In the construction of the power grid and equipment maintenance, various safety measures must be implemented to prevent minor personal injuries and above-mentioned accidents. The State Grid Corporation of China stipulates that when working on a scaffold without scaffolding or without railings and the height exceeds 1.5 meters, safety belts should be used or other reliable safety measures should be taken. There are also regulations: the hook or rope of the seat belt should be hung on a strong and firm component, or on a steel wire rope specially used for hanging the seat belt, and should be hung high and low. It is forbidden to hang on moving or unstable objects [such as isolating switch (knife switch) support insulators, CVT insulators, busbar post insulators, lightning arrester post insulators, etc.].

Now there are some problems in the high-altitude operation of the substation: 1. Safety belts should be used if the height exceeds 1.5 meters, but according to the regulations, the supporting insulators of the isolating switch (knife switch), CVT insulators, busbar post insulators, and lightning arrester post insulators cannot be hung. If the safety belt is hung on the insulator, it is a violation of regulations. When the insulator breaks, it will cause a high-altitude fall and personal safety accident; 2. The violation of the safety belt hanging on the insulator occurs repeatedly during on-site supervision by safety supervisors; 3. Substations The intervals are limited, and most of the interval arm trucks cannot enter the work site, and the bucket arm trucks cannot be used; 4. When setting up a landing operation platform, the electrical safety distance is not easy to meet the requirements, and the erection time is long; 5. No special equipment for sale; 6. For many years, it has been unable to solve the illegal behavior of porcelain pillar type high-altitude operations such as electrical maintenance knife switches in substations.
