Labor-saving anti-falling device

Abstract

The invention provides a labor-saving anti-falling device. The labor-saving anti-falling device includes an anti-falling device; the anti-falling device includes a rotating part and a fixed part; therotating part is rotatably arranged on the fixed part through a first rotating shaft; at least one hook is rotatably arranged on the rotating part; a limit rod is arranged on the fixed part; and the rotation of the rotating part generates a centrifugal force, so that the hook hooks the limit rod, thereby realizing the limit of the rotating part. The labor-saving anti-falling device also includes aladder-climbing labor-saving device; the first rotating shaft is fixedly connected to the rotating part; the end of the first rotating shaft is connected to the ladder-climbing labor-saving device; and the limit of the ladder-climbing labor-saving device is realized by the hook hooking the limit rod. The centrifugal force generated by the rotation of the rotating part is used for throwing the hook out, so that the hook can hook the limit rod, which ingeniously utilizes the centrifugal force to realize the limit, meets the requirements of anti-falling, and prevents the rotating part from rotating too fast, that is, prevents the operating personnel from moving too fast in the air, and plays a role of speed limiting.

Description

technical field [0001] The invention relates to the technical field of anti-fall protection devices, in particular to a labor-saving anti-fall device. Background technique [0002] Tower cranes are large-scale mechanical equipment commonly used on construction sites. They are widely used because of their high lifting height and wide coverage. The installation and dismantling personnel and drivers of the tower crane need to go up and down on the tower crane through the ladder on the tower crane. In order to make it easier for people to go up and down the tower crane, they generally use a ladder labor-saving device to assist, that is, to reduce the gravity of the personnel through the counterweight, so that it is easier to climb up and down the ladder. Light and fast, greatly reducing the difficulty of getting on and off the tower crane and the labor intensity of personnel. [0003] Although the labor-saving device for climbing the ladder can reduce the difficulty of personne...

Problems solved by technology

[0003] Although the labor-saving device for climbing the ladder can reduce the difficulty of personnel getting on and off the tower crane, there are also situations where the operator climbs the ladder too fast. In this case, it is easy to step on the ground; Even if the foot slips, there will also be a stepping event, so it is necessary to add a corresponding anti-fall device to prevent the stepping down event and control the climbing speed of the operator
