Anti-falling safety device of lifting scaffold

Abstract

The invention discloses an anti-falling safety device of a lifting scaffold, and particularly relates to the technical field of scaffold falling prevention. The anti-falling safety device comprises a supporting plate, a storage groove is formed in one side of the supporting plate, a storage mechanism is arranged in the storage groove, and a mounting mechanism is arranged on the other side of the supporting plate; the storage mechanism comprises a transmission lead screw, the transmission lead screw is sleeved with a first threaded ring, and a second threaded ring is arranged on one side of the first threaded ring. The storage mechanism is arranged, a servo motor rotates forwards to drive the transmission lead screw to enable the first threaded ring to move leftwards, meanwhile, the second threaded ring moves rightwards under the action of threads, in this way, a stretching elastic strip begins to contract, therefore, rapid closing and storage of a protective net are achieved; multiple buffering protection effects are achieved in the protective net, the buffering effect is effectively achieved, safety is greatly improved, operation is easy, use is easy, more time and labor are saved, the repeated utilization rate is higher, and practicability is better.

Description

technical field [0001] The invention relates to the technical field of scaffolding fall prevention, and more specifically, the invention relates to a fall prevention safety device for a lifting scaffold. Background technique [0002] Before 1949 and the early 1950s in China, construction scaffolds were constructed using bamboo or timber. Since the 1960s, fastener-type steel pipe scaffolding has been promoted. Scaffolding refers to various supports erected on the construction site for workers to operate and solve vertical and horizontal transportation. The generic term on building circle, refers to building site be used in the higher place that cannot directly construct of exterior wall, interior decoration or floor height. Mainly for the construction personnel to work up and down or the peripheral safety net enclosure and high-altitude installation components, etc., it is necessary to lay protective nets in the construction scope of the scaffolding, so as to prevent the acc...

AI Technical Summary

Problems solved by technology

[0003] However, in actual use, such as the general process of laying the protective net, the laying range is small, and once there is a fall from a high place, it is easy to cause accidental falls, and the opening and later recovery of the protective net during the laying process need to be done manually. Recycling, not only is it more troublesome to recycle, but also the recycling process is more dangerous, less safe, more time-consuming and labor-intensive, and less practical
