Falling safety protection system comprehensive performance tester and testing method thereof

Abstract

The invention provides a comprehensive performance tester for a falling safety protection system. The tester includes a bottom plate and a top plate, and four stand columns are fixedly connected between the bottom plate and the top plate; a first installation platform and a second installation platform which are fixedly connected with the four stand columns are sequentially arranged below the topplate, the bottom of the end, extending out of the four stand columns, of the first installation platform is fixedly connected with an impact sensor, a first hanging ring of the impact sensor is connected with a first buffer bag, the first buffer bag is connected with a first safety rope, and the first safety rope is connected with a safety belt worn on a first test dummy; and a tension sensor isfixedly connected to the middle of the bottom of the second installation platform, a second hanging ring of the tension sensor is connected with a second buffer bag, the second buffer bag is connectedwith a second safety rope, the second safety rope is connected with a safety belt worn on a second test dummy, and the second test dummy is connected with an oil cylinder through a third safety rope.The tester is convenient to operate, high in test efficiency, accurate and reliable in test data and capable of testing the static performance of the falling safety protection system.

Description

technical field [0001] The invention relates to a comprehensive performance tester for a fall safety protection system and a testing method thereof, belonging to the field of performance parameter testing of a fall safety protection system. Background technique [0002] According to the statistical analysis of high-altitude fall accidents, the high-altitude fall accidents above 5m account for about 20%, and those below 5m account for about 80%. Most of the former are fatal accidents. Therefore, it is very necessary to provide fall protection for high-altitude workers so that they can effectively avoid the huge damage to the human body caused by the fall when they accidentally fall from high altitude. [0003] The fall safety protection system includes safety ropes, cushioning bags, seat belts and hardware accessories. The protection technology and equipment originated in Europe. Both Europe and the United States have conducted systematic research on fall safety protection. T...

Problems solved by technology

[0004] The performance indicators of the fall safety protection system include the impact force generated during the fall process, the static tension force of the seat belt, safety rope, and buffer package, etc. The smaller the impact force and the higher the static tension force of the parts during the fall process, the The safety performance of the system is better. At present, although there have been preliminary research and construction of dynamic performance testers and static performance testers for fall safety protection systems in China, they are all single dynamic performance testers or static performance testers.

[0005] In view of this, there is currently a lack of a comprehensive performance tester that is simple and convenient to operate and integrates static and dynamic performance tests of the fall safety protection system.
