Embodiment 1

[0038] Such as figure 1 and figure 2 As shown, the anti-fall runner used on the fall arrester includes the runner body and a plurality of radial lugs 3 arranged on the runner body, and also includes The second block 4, 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 direction, the second block 4 is installed on the runner body or the radial lug 3 through the chute 5, and during the rotation of the runner body, the second stop 4 can slide along the length direction of the chute 5 .

[0039] 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 direction of the guide rail. Arra...

Embodiment 2

[0045] 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 apply rotation constraints for the anti-falling wheel in time when the speed of the anti-falling wheel increases, it is set as follows: the second stopper 4 is a plurality of , and a plurality of second stoppers 4 are arranged at intervals along the circumferential direction of the runner body.

[0046] A plurality of radial lugs 3 are evenly distributed in a ring with respect to the axis of the runner body.

[0047] Each radial lug 3 is strip-shaped, and the length direction of each radial lug 3 is located in the radial direction of the runner body;

[0048] Each radial lug 3 is provided ...

Abstract

The invention discloses an anti-fall runner used on a fall arrester, which comprises a runner body and a plurality of radial lugs arranged on the runner body, and also includes radial lugs installed on the runner body or The second block on the runner body or the radial lug is provided with a chute, the chute is a bar-shaped groove, and the length direction of the chute is along the radial direction of the runner body. The second stopper is installed on the runner body or the radial lug through the chute, and the second stopper can slide along the length direction of the chute during the rotation of the runner body. The anti-falling wheel has simple structure and reliable performance.

Description

technical field [0001] The invention relates to the technical field of equipment for building construction, in particular to an anti-fall rotating wheel used on an anti-fall device. 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 example, the utility model pat...
