Speed anti-falling device for integral lifting climbing frame

Abstract

The invention relates to a speed anti-falling device for an integral lifting climbing frame. The speed anti-falling device for an integral lifting climbing frame comprises an anti-falling hanging pedestal, a guide rail and a connecting mechanism; one end of the anti-falling hanging pedestal is fixedly connected to the outer wall of a building, and a paddle and a shifting gear are arranged at the other end of the anti-falling hanging pedestal. The paddle and the shifting gear are both rotatably connected with the anti-falling hanging pedestal through a same fixing bolt. The guide rail is installed on a climbing frame body, ladder gears are arranged equidistantly in the axial direction, the guide rail is connected with the anti-falling hanging pedestal through the connecting mechanism, the ladder gears are matched with the paddle and the shifting gear, the shifting gear is provided with a first limiting protrusion, the first limiting protrusion is located under a blocking piece, a secondlimiting position is arranged on the anti-falling hanging pedestal, and the second limiting protrusion is located under the shifting gear. The speed anti-falling device for an integral lifting climbing frame can solve the problem of falling prevention in the climbing frame rising and falling process, has the advantages of reasonable design, scientific structure, simple operation, safety and reliability and high work efficiency, and can be widely used in construction.

Description

technical field [0001] The invention belongs to building construction, and in particular relates to a speed anti-drop device for an integral lifting climbing frame. Background technique [0002] In the existing building construction technology, the overall lifting climbing frame is widely used, and its lifting process is generally as follows: one end of the electric hoist is fixed on the building, the other end is connected to the climbing frame body, the electric hoist is started, and the electric hoist Forward or reverse rotation, to achieve the overall rise or fall of the climbing frame. However, due to the unbalanced load weight and the difference in the manufacture of the electric hoist, the speed of the electric hoist may vary from fast to slow, especially during the operation of the climbing frame, the electric hoist may fail or scratch with the building, resulting in the electric hoist Overloading, even the chain breaks, causing a fall safety accident on the climbin...

AI Technical Summary

Problems solved by technology

[0003] Due to design reasons, most of the current anti-drop devices for climbing frames can only prevent falling when the climbing frame is raised as a whole, but cannot prevent falling when the climbing frame is lowered as a whole.

However, the climbing frame anti-falling device that can realize the anti-falling effect during the climbing frame's rising and falling process has a relatively complicated structure and is not convenient for installation on the construction site.
