Anti-drop device

Abstract

The invention relates to an anti-drop device which can effectively solve the problems that an anti-drop system of an attached type lifting scaffold is not ideal in brake effect, has potential safety hazard, and is complicated in structure, troublesome in installation and use and high in cost. The anti-drop device has the technical scheme that the device comprises a guide support seat, a limit supporting device and a dropping protector, wherein the front end of the guide support seat is provided with a guide chuck; the limit supporting device is arranged at the upper part of the guide support seat by a pin shaft, so that a first movable rotating structure can be formed; the lower part of the guide support seat is provided with the dropping protector; the dropping protector comprises a support frame, a deflecting cam and an anti-drop block; the support frame is connected with the lower part of the guide support seat, and the anti-drop block is arranged on the support frame by a linkage pin shaft, so that a second movable rotating structure can be formed; a blocking head is arranged at the upper part of the anti-drop block; the lower part of the anti-drop block is provided with the deflecting cam. The anti-drop device is novel and unique in structure, simple and reasonable, convenient to assemble and disassemble, labor-saving, time-saving, material-saving, efficient, good in dropping prevention effect, safe and reliable, thus being an innovation of a anti-drop system.

Description

technical field [0001] The invention relates to construction equipment in the construction field, in particular to a fall prevention device for an attached lifting scaffold. Background technique [0002] At present, the attached lifting scaffolding in high-rise buildings gradually replaces the traditional bottom-supporting fixed scaffolding. Compared with traditional scaffolding, the main advantages of lifting scaffolding are: 1. Good economic performance: no matter how high the building is, it only takes four to use lifting scaffolding. ~Five layers of revolving materials, saving material rental costs, the frame body is erected at one time, no need for tower crane cooperation, revolving materials are less wasted and lost during use, and the cost of using tower cranes is saved. 2. Good safety performance: Since the lifting scaffolding starts to be erected at the first standard floor of the building, it avoids the continuous erection and disassembly of the scaffolding body in...
