Automatic falling preventing device for integral lifting scaffold

Abstract

The invention relates to building construction equipment and discloses an automatic falling preventing device for an integral lifting scaffold, which is characterized by comprising an attached vertical plate, an upper cover plate, a lower cover plate, a hanger plate, an upper limit block, a lower limit block, an oblique stripped hole, a spring seat, a compression spring, a left baffle, a right baffle, a brake bar and a sliding shaft, wherein the attached vertical plate is fixed to a wall of a building; the upper cover plate and the lower cover plate are transversely fixed on the attached vertical plate in parallel; the hanger plate passes through the upper cover plate and the lower cover plate in a vertical sliding way; the upper limit bock and the lower limit block are arranged on the hanger plate and arranged outside the upper cover plate and the lower cover plate; the oblique stripped hole is arranged in the middle-upper part of the hanger plate; the spring seat is arranged at the middle-lower part of the hanger plate; the compression spring is arranged between the spring seat and the lower cover plate; the left baffle and the right baffle are vertically fixed between the uppercover plate and the lower cover plate in parallel; the brake bar passes through the left baffle and the right baffle in a horizontal sliding way; the sliding shaft is vertically arranged on the brakebar; the sliding shaft is vertical to the hanger plate and extends into the oblique stripped hole in the hanger plate; and a working pull ring is arranged at the lower part of the hanger plate.

Description

Technical field [0001] The invention relates to building construction equipment, in particular to an automatic fall prevention device for integral lifting scaffolding. Background technique [0002] At present, the overall lifting scaffolding used in the construction and decoration of high-rise buildings has low cost, simple structure and convenient operation. Compared with traditional scaffolding, it can reduce installation and operation personnel and greatly improve the efficiency of building construction. It has been used in the construction industry. It is widely used. However, in the process of lifting, lowering and using the frame, falling incidents occur from time to time, causing serious harm to the life and safety of construction personnel. [0003] The anti-falling device for integral lifting scaffolding mostly adopts wedge brake clamping wire rope type, steel suspension rod type and other anti-falling forms. The overall structure and transmission form are more complicate...

AI Technical Summary

Problems solved by technology

However, during the lifting, lowering and use of the frame, falling incidents occur from time to time, causing serious harm to the life safety of construction workers.

[0003] Most of the anti-fall devices used for overall lifting scaffolding adopt the anti-fall forms such as wedge brake clamping wire rope type and steel suspender type. The overall structure and transmission form are relatively complicated and the reliability is poor; The first fall occurred, and a similar situation existed for the steel boom type
