The invention relates to a fall preventing device of a climbing frame. The fall preventing device comprises a fall preventing block, a guiding rack, a rack body, a return spring, a limiting block, a pin shaft, at least two ladder rods, a braking tooth, an activating tooth and a buffer spring, wherein the rack body and the guiding rack are in sliding-fit connection, the fall preventing block is rotatably mounted on the guiding rack through the pin shaft of the fall preventing block and comprises the activating tooth and the braking tooth, and the activating tooth is located below the braking tooth; the limiting block is arranged on the guiding rack and is located below the fall preventing block; the at least two ladder rods are arranged on the rack body in the sliding direction; one end of the return spring is fixedly connected to the guiding rack, the other end of the return spring is fixedly connected to the fall preventing block, the buffer spring and the return spring are oppositely mounted, one end of the buffer spring is fixedly connected to the guiding rack, and the other end of the buffer spring is fixedly connected to the fall preventing block. The fall preventing device has the advantages of safety, reliability, simple structure, relatively low cost and exact action time.
Description
【Technical field】 [0001] The invention relates to a lifting device and a safety device supported by a wall, in particular to an anti-falling device for a climbing frame. 【Background technique】 [0002] With the progress of society, the construction industry is developing rapidly, and there are more and more high-rise and super high-rise construction industries in various forms. In the construction of high-rise buildings, climbing scaffolding is indispensable. Because climbing scaffolding has the advantages of less investment, convenient use, simple operation and strong practicability, it has been favored by the majority of construction units; and climbing scaffolding After setting up, it is necessary to lift the frame body, that is, use the lifting system of the scaffold to lift the frame body. Since it is a high-rise building, the safety of the frame body lifting is very important. How to install safety devices during the frame body lifting process, It is related to the li...
