Embodiment 1

[0035] Such as figure 1 with figure 2 As shown, the anti-falling device used for lifting scaffolding includes a frame body 1 and an anti-falling wheel 2 installed on the frame body 1. The anti-falling wheel 2 is installed on the frame body 1 through a wheel shaft, and the anti-falling wheel 2 It can rotate around its own axis; the outer edge of the anti-fall wheel 2 is also provided with a plurality of radial lugs 3, which is characterized in that it also includes a slider installed on the anti-fall wheel 2 or on the radial lugs 3 4. A chute 5 is provided on the anti-falling wheel 2 or on the radial lug 3, the chute 5 is a bar-shaped groove, and the length direction of the chute 5 is along the radial direction of the anti-falling wheel 2, The slider 4 is installed on the anti-fall wheel 2 or the radial lug 3 through the chute 5, and the slider 4 can slide along the length direction of the chute 5 during the rotation of the anti-fall wheel 2;

[0036] It also includes a stop...

Embodiment 2

[0045] Such as figure 1 with 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 rapidly. In order to make the anti-fall wheel 2 increase in speed, the stopper 6 can in time apply the rotation constraint for the anti-fall wheel 2. It is set as follows: the slide block 4 is multiple, and A plurality of sliders 4 are arranged at intervals along the circumferential direction of the anti-fall wheel 2 . This scheme is adopted to achieve the purpose of short anti-falling distance.

[0046] In order to adapt to the uniformly arranged crossbars on the track in the prior art, it is arranged that a plurality of radial lugs 3 are evenly distributed in a ring with respect to the axis of the anti-fall wheel 2 .

[0047] As a s...

Abstract

The invention discloses a fall prevention device for a lifting scaffold. The fall prevention device includes a scaffold body and a fall prevention wheel; a plurality of radial support lugs are arranged at the outer edge of the fall prevention wheel; the fall prevention device is characterized by further including sliding blocks mounted on the fall prevention wheel or the radial support lugs, sliding grooves are formed in the fall prevention wheel or the radial support lugs and are strip-shaped grooves, the length direction of the sliding grooves is arranged along the radial direction of the fall prevention wheel, the sliding blocks are mounted on the fall prevention wheel or the radial support lugs through the sliding grooves, and when the fall prevention wheel rotates, the sliding blockscan slide in the length direction of the sliding grooves; the fall prevention device further includes a baffle block mounted on the scaffold body, and in the process that the sliding blocks rotate along with the fall prevention wheel, when the rotation speed of the fall prevention device is greater than a preset threshold value, the baffle block partially or completely falls in the motion trajectory of the sliding blocks; when the sliding blocks and the baffle block interacts with each other, the baffle block exerts resistance for impeding further rotation of the sliding blocks on the slidingblocks. The fall prevention device for the lifting scaffold is simple in structure and reliable in performance.

Description

technical field [0001] The invention relates to the technical field of equipment for building construction, in particular to a fall arrester for 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 example, the utility model patent with applicat...
