A fall prevention device for c-shaped steel guide rail

Abstract

The invention proposes a fall prevention device for a C-shaped steel guide rail, which includes a main body, a movable body, a hinge seat and a locking part; the main body includes a first fixed part and a second fixed part, the movable body includes a movable part and a trigger part, and the movable The part can move horizontally toward the direction of the second fixed part. The locking part has a first movable end and a second movable end. The first movable end is located in the cavity and the second movable end is located in the first interval. At the same time, the second movable end is screwed into the cavity and the first movable end is screwed into the first interval, the guide rail moves along the vertical line, and the flange is located in the first interval and the second interval; through friction and The downward impact force will cause the trigger part to move away from the movable part, thereby driving the first movable end to screw into the first space and approach the second fixed part, thereby clamping the flange of the guide rail to the first movable end Between the guide rail and the second fixing part, the purpose of preventing the guide rail from falling is achieved.

Description

technical field [0001] The invention relates to the technical field of guide rail anti-fall technology, in particular to an anti-fall device for a C-shaped steel guide rail. Background technique [0002] Attached lifting scaffolding equipment is a new type of scaffolding technology developed rapidly at the beginning of this century, which has an important impact on the progress of construction technology in our country. It changes the high-altitude operation into the low-altitude operation, and changes the suspended operation into the internal operation of the frame. It has the characteristics of low carbon, high-tech content, more economical, safer and more convenient. Attached lifting scaffold refers to an external scaffold that is erected at a certain height and attached to the engineering structure, relying on its own lifting equipment and devices, which can climb or descend layer by layer with the engineering structure, and has anti-overturning and anti-falling devices;...

AI Technical Summary

Problems solved by technology

[0003] When the wall mount is used in conjunction with the guide rail, in order to prevent the guide rail from falling freely under the influence of gravity after accidentally losing its support, an anti-fall mechanism is generally installed on the wall mount or the guide rail separately. By adjusting the forward and reverse functions of the anti-fall mechanism, the guide rail only Can run along the wall in one direction, this structure will make it inconvenient to adjust the height of the guide rail
