Embodiment 1

[0043] Such as figure 1 and figure 2 As shown, the anti-fall runner with controllable fall maximum speed of the lifting scaffold includes the runner body and a plurality of radial lugs 3 arranged on the runner body, and also includes radial lugs installed on the runner body or The second block 4 on 3, during the rotation of the runner body, the second block 4 can reciprocate along the radial direction of the runner body under its own weight;

[0044] An adjustment device is also included, the adjustment device is used to limit the minimum distance between the second block 4 and the axis of the runner body, and the minimum distance is adjustable.

[0045] In the prior art, as shown in the technology disclosed in the utility model patent with the application number 201020668449.2, a guide rail is provided on the lifting scaffold, and a plurality of cross bars are installed on the guide rail, and the plurality of cross bars are sequentially arranged along the extending directio...

Embodiment 2

[0052] Such as figure 1 and figure 2 As shown, this embodiment is further limited on the basis of Embodiment 1: as a person skilled in the art, since the relative position of the radial lugs 3 needs to match the relative position of the specific upper cross bar of the scaffold, any radial The lugs 3 can constrain the scaffold to fall further quickly. In order to make the second stopper 4 timely impose rotation constraints on the anti-falling wheel when the speed of the anti-falling wheel increases, as the specific assembly of the second stopper 4 in this scheme way, the runner body or the radial lug 3 is provided with a chute 5, the chute 5 is a bar-shaped groove, and the length direction of the chute 5 is along the radial direction of the runner body, the second The stopper 4 is installed on the runner body or the radial lug 3 through the end embedded in the chute 5; the second stopper 4 is multiple, and the plurality of second stoppers 4 are arranged along the circumferenc...

Abstract

The invention discloses a fall prevention rotating wheel with a controllable lifting scaffold fall maximum speed. The fall prevention rotating wheel comprises a rotating wheel body, a plurality of radial support lugs, a second stopper and an adjusting device, the radial support lugs arranged on the rotating wheel body, the second stopper is mounted on the rotating wheel body or radial support lugsand can reciprocate along the radial direction of the rotating wheel body under dead weight of the second stopper in the rotating process of the rotating wheel body, the adjusting device is used forlimiting shortest distance between the second stopper and the axis of the rotating wheel body, and the shortest distance can be adjusted. The fall prevention rotating wheel is simple in structure, andthe scaffold fall maximum speed can be controlled.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to an anti-falling wheel with a controllable maximum falling speed of a lifting scaffold. Background technique [0002] Lifting scaffolding equipment is a new type of scaffolding developed rapidly at the beginning of this century, which has an important impact on the progress of construction technology in our country. [0003] Elevating scaffolding 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, can climb or descend layer by layer with the engineering structure, and has anti-overturning and anti-falling devices. Among them, the anti-falling device is a lifting It is an important safety accessory on the scaffolding, which can restrain the scaffolding when the scaffolding falls abnormally, so as to avoid accidents. [0004] In the prior art, for exam...
