Description

Technical Field

[0001] The invention relates to the technical field of guide rail fall arresters, in particular to an aluminum alloy T-shaped guide rail fall arrester. Background Art

[0002] The attached lifting scaffold refers to a lifting equipment and device that is erected at a certain height and attached to the engineering structure, relying on its own lifting equipment and devices, and can climb or descend layer by layer with the engineering structure. A guide rail is fixedly installed on one side of the attached lifting scaffold, which cooperates with a fall arrester fixed on one side of the wall to prevent the guide rail from accidentally losing support and falling. Existing fall arresters, such as the lifting scaffolding anti-fall structure with a simple anti-fall guide rail disclosed in the authorization announcement number CN213710323U, set the bottom of the anti-fall cross bar to a plane. When the anti-fall cross bar rises or descends normally, the anti-fall stop arm quickly separates from the anti-fall cross bar under normal circumstances to avoid being stuck due to conflict between the two; when the frame falls, the anti-fall stop arm rotates downward and then has no time to reset and immediately engages with the next anti-fall cross bar, thereby preventing the frame from continuing to fall; and the anti-fall stability of the structure is effectively improved through surface contact.

[0003] The existing fall arrester is installed on one side of the wall through a bracket, and the guide rail fixed on the lifting scaffold is in sliding contact with the fall arrester, and the anti-fall baffle and the limit plate are rotatably installed on the fall arrester, and multiple cross bars are installed on the guide rail. When the guide rail rises or falls slowly, the anti-fall baffle is driven to rotate by the cross bar, and the gap between the cross bar and the anti-fall baffle is used to reset the anti-fall baffle. Therefore, when the guide rail rises or falls slowly, the protection mechanism will not be triggered, and the staff can lift the scaffold normally. When the guide rail falls quickly, the anti-fall baffle has no time to reset, and the limit plate will be driven to resist the cross bar to achieve limitation. This is similar to the above-mentioned prior art, but the scaffold and the guide rail fall at the same time, the weight is large, and only the limit plate is used for support, and the safety factor is low.
