Description

Height adjustable anti-fall aerial work platform

technical field

The utility model relates to the technical field of electric power maintenance equipment, in particular to a height-adjustable anti-fall aerial work platform.

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) supporting 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. If the height exceeds 1.5 meters, safety belts should be used, but the safety belts cannot be hung on the supporting insulators of the isolating switch (knife switch), CVT insulators, busbar post insulators, and lightning arrester post insulators. If it is hung on the insulator, it is a serious violation of regulations. When the insulator breaks, it will cause a high-altitude fall personal safety accident; 2. The violation of the safety belt hanging on the insulator occurs repeatedly during on-site supervision by safety supervisors; 3. Bucket trucks cannot Entering the work site, 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 it takes a long time to set up; 5. There is no special equipment for sale; 6. When checking the knife switch or circuit breaker, you can only stand On the bracket channel steel, it affects work efficiency; 7. It has been unable to solve the illegal behavior of substation electrical maintenance at high places for many years. Therefore to develop substation high-altitude work anti-falling platform.
