Abstract

The invention relates to a built-in buffering type anti-falling device. The built-in buffering type anti-falling device comprises a shell body, brackets, a rotating plate, a steel wire rope and a hook. Two anti-rotation teeth are hinged to the rotating plate and elastically folded. Inner tooth disks are fixedly connected to the brackets and provided with friction pieces to form a friction buffering type speed difference anti-falling mechanism. The hook is provided with an indicating device. The built-in buffering type anti-falling device has the advantages that when the inner tooth disks are thrown off and clamped by the centrifugal force of the anti-rotation teeth in the falling process, the inner tooth disks are slowly rotated, the friction is stopped, and the inner tooth disks are not immediately locked, so that a buffering stage is produced, the anti-falling impact force is reduced, a human body is prevented from being injured, the situation that personnel are suddenly pulled due to overquick movement is prevented, and the safety is improved; in addition, whether the anti-falling device loses efficacy is judged through the indicating device, and thus the phenomenon that the invalid anti-falling device is used by the operating personnel is avoided, and the absolute security of operation is ensured; the two anti-rotation teeth are elastically folded through an elastic connecting piece, and hence the effect that no noise exists during operating is ensured.
