Device and system for preventing falling

Abstract

The invention provides a device and system for preventing falling, wherein the device comprises a casing, a rotating fixture block, a fixed shaft, a sliding wheel, a sliding buffer block and a buffer spring, a falling-preventing buffer device consisting of the rotating fixture block, the sliding buffer block and the buffer spring can penetrate through the bottom of the casing, and the fixed end of the falling-preventing buffer device is arranged in the casing and is movably connected with the casing through the fixed shaft so as to lead the falling-preventing buffer device consisting of the rotating fixture block, the sliding buffer block and the buffer spring to rotate in the casing around the fixed shaft. The invention can solve the safety problems of ascending, backing, transferring and high-attitude fixing operations of the high-attitude operating staff so as to lead the high-attitude operating process to be protected better, and can greatly lower the huge impact force of the falling brake to the operating staff through the buffer function of the falling-preventing buffer device when sudden falling occurs, thereby effectively protecting the operating staff from being hurt.

[0002] In the fields of power transmission and transformation line towers, power transformation structures, communication towers and buildings, etc., climbing operations are inseparable. In recent years, the development of electric power has been rapid, and the requirements for safety management have become higher and higher. Power grid construction and transformation The work tasks are getting heavier and heavier. A large number of construction and maintenance tasks involve climbing operations. If there is no reliable fall prevention equipment, it will bring huge safety hazards to the operators.

[0003] For this reason, many designers in the industry have researched and developed anti-fall safety devices for high-altitude operations, but the anti-fall devices used for high-altitude operations are mainly produced by the interaction between the anti-fall devices and guide rails. If an accident occurs to the operator of the anti-fall device used in the operation, if the operator does not lean back and then fall, the anti-fall device will slide down for a certain distance before braking with the guide rail, but this braking method is It belongs to rigid braking, which exerts a great force on the body of the operator, so there is no buffer and it will inevitably cause certain damage to the body of the operator

[0004] At present, the industry mainly adopts this aspect of high-altitude fall protection buffering: (1) install a section of elastic buffer belt on the safety belt, and reduce the impact of the rope tension on the human body by the buffering effect of the elastic buffer belt when falling accidentally. But this kind of elastic cushioning belt is not ideal in the middle of actual application, and can not repeatedly use repeatedly, needs further improvement; One section consists of two layers of nylon belt or double-layer damping belt. When the operator accidentally falls from a high place, the falling tension of the human body will tear the two layers of nylon belt or damping belt, and the buffering will be realized by the tearing force.

But adopt this kind of cushioning method because the active force is limited, can not realize reducing impact force to the harmful effect to human body to a great extent, and promptly scrapped after only one-time use; There is a curved seam running through the rotating part on one side of the rotating block. When a person falls, the safety belt on the rotating block will be pulled away by the falling operator after the fall arrester is stuck on the guide rail and braked. Rotate the body of the block, creating a cushioning effect

However, the current status of this technology is that when the side of the safety belt on the rotating block is pulled along the curved seam, the operator who falls will be pulled away from the main body of the rotating block, and the safety of the personnel can be ensured when the destructive pull is carried out. The fall buffer technology is only theoretically realized, and no manufacturer can actually manufacture it

Moreover, the anti-fall device can only be discarded after one-time anti-fall, and cannot be reused safely. The requirements for production materials are high, and the manufacturing cost is high.
