A t-shaped guide rail fall arrester

Abstract

The present invention proposes a T-shaped guide rail fall arrester, which includes a main body, a first movable body, a hinge mechanism and a locking part. There is a cavity on the side. The first movable body includes a first movable part and a first trigger part. The first movable part is slidably connected to the upper surface of the first fixed part and can move horizontally in the direction of the second fixed part. The locking part is located in the cavity. In the groove, the locking part has a movable end, and the movable end can rotate clockwise or counterclockwise around the horizontal line between the abutment surface and the end surface of the guide rail facing the wall; when the guide rail falls freely, through the friction force and the downward impact force It will cause the trigger part to move away from the wall, drive the movable end to screw into the first space and approach the second fixed part, and press the movable end, so that the flange plate of the guide rail is fixedly clamped between the movable end and the second fixed part. Between the two fixed parts, the purpose of preventing the guide rail from falling is realized.

Description

technical field [0001] The invention relates to the technical field of anti-drop technology for guide rails, in particular to a T-shaped anti-fall device for guide rails. 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; th...

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
