Problems solved by technology

However, there are certain disadvantages in the safety belts of conventional safety protection products for working at heights: the safety belts can only be used at fixed operating points and must be used correctly to play a protective role. If workers want to move, they must untie the safety belts, but they cannot Wearing a seat belt greatly increases the risk of falling
The usual solution is to install a vertical rope in the vertical movement area, but the commonly used safety fall arresters mostly use the centrifugal principle, there is only one safety device, and the safety rope needs to be rolled into it, and the usage is relatively simple during use How inconvenient

Abstract

The present invention provides a new type of anti-falling device, which includes a horizontally arranged main shaft and a second locking mechanism, the end of the main shaft is connected with the second locking mechanism, and the main shaft includes a safety belt winding area, a second A locking mechanism and a connecting mechanism, the first locking mechanism includes an outer card shaft integrally formed with the main shaft and a sleeve sleeved on the outside of the outer card shaft, an inner card shaft is arranged inside the sleeve, and the inner card shaft The inner diameter of the shaft is larger than the outer diameter of the outer card shaft. The main shaft also includes a rebound mechanism arranged at the head end for controlling the return of the main shaft. The end of the main shaft is connected to the second locking mechanism through a connecting mechanism. The first locking mechanism and the second locking mechanism cooperate to achieve double locking of the main shaft, ensuring the safety of high-altitude operations and reducing the occurrence of falling accidents. The invention is simple in structure, convenient and practical, has double anti-falling systems, can increase the safety of high-altitude operations, reduce falling accidents, and has diversified uses.

Description

technical field [0001] The invention belongs to the technical field of building construction safety, and in particular relates to an anti-falling device. Background technique [0002] According to statistics, accidents of falling from heights on construction sites remain high. The main reason is that personnel working at heights (the height of the falling reference level is greater than 2 meters) lacks correct safety protection, and the last line of defense after falling is the safety rope. Or the seat belt is not fastened effectively or is not used correctly. According to the "Safety Technical Specifications for Building Construction Work at Heights" (JGJ80-2016), personnel working at heights should wear and use safety protective equipment for operations at heights in accordance with the regulations, and should be inspected by special personnel. However, there are certain disadvantages in the safety belts of conventional safety protection products for working at heights: t...
