Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of anti-falling device structure design, and in particular relates to an anti-falling device with a buffering function. Background Art
[0002] High-altitude fall prevention is a crucial task for State Grid, as falls from height are a serious safety issue in power construction. Major accidents can not only cause casualties but also severely impact power supply. Therefore, State Grid prioritizes high-altitude fall prevention and implements strict preventive measures. This work is widely used and implemented in my country's power construction, achieving significant results.
[0003] To achieve cushioning, common fall arresters on the market typically incorporate an elastically stretchable safety belt. This allows the belt to act as a buffer when a person wearing the safety belt falls, slowing their fall. This design must consider factors such as the belt's length, elastic coefficient, the height of the work being performed, and the weight of the person. Furthermore, if the work height doesn't match the ideal length of the safety belt, the belt could fail to rebound before the person falls to the ground. To address this technical issue, our company offers a fall arrest device with a cushioning function. Utility Model Content
