Description

Technical Field

[0001] The utility model relates to the technical field of drying, in particular to a safety protection device for an attached lifting scaffold. Background Art

[0002] An attached lifting scaffolding refers to an external scaffolding that is erected at a certain height and attached to the engineering structure. It relies on its own lifting equipment and devices to climb or descend layer by layer with the engineering structure. It has anti-overturning and anti-falling devices. It turns high-altitude operations into low-altitude operations and suspended operations into operations inside the frame.

[0003] However, there is still a certain gap between the attached scaffolding and the wall, and this gap still poses a risk of construction workers getting their feet stuck or dropping construction tools. For this reason, under existing conditions, a safety protection device for an attached lifting scaffolding is used, as disclosed in announcement number CN220014410U. The device is provided with a tensioning assembly that cooperates with the elastic force of a spiral spring so that multiple sets of winding sleeves can ensure that all positions of the fan-shaped protection net are in a tensioned state when the long protection net frame and the short protection net frame are unfolded upward to avoid the occurrence of a nested condition. However, two sets of supporting structures need to be set for the long protection net frame, and two sets of driving equipment need to be set at the same time, which will lead to an increase in the overall manufacturing cost and weight of the protection device, and will also increase the volume and weight burden of the lifting scaffolding.
