Description

Anti-falling device for guide rail type lifting scaffold

Technical Field

The utility model relates to a scaffold equipment technical field specifically is a falling prevention device for guide tracked lifting foot hand rack.

Background

The scaffold is a working platform which is erected for ensuring that each construction process is smoothly carried out. The scaffold is divided into an outer scaffold and an inner scaffold according to the erected positions; the scaffold can be divided into a wood scaffold, a bamboo scaffold and a steel pipe scaffold according to different materials; the scaffold is divided into a vertical rod type scaffold, a bridge type scaffold, a door type scaffold, a suspension type scaffold, a hanging type scaffold, a lifting type scaffold and a climbing type scaffold according to the structural form. At present, but inserted lift scaffold replaces the fixed scaffold of traditional bottom sprag gradually among the high-rise building, and lift scaffold compares convenient operation, application range with traditional scaffold greatly, but it has the risk of tipping, falling, chain rupture. The anti-falling component has the defects of complex structure, more parts and inconvenient installation and maintenance, and the common anti-falling device is lack of multiple buffer devices and has limited buffer effect. To this end, we propose a fall arrest device for a rail-type lifting scaffold.
