Attached lifting scaffold servo triggering anti-drop device

Abstract

Disclosed is an attached lifting scaffold servo triggering anti-drop device. The device comprises a fixed steel beam and a guide rail; the fixed steel beam is internally provided with a servo triggering anti-drop device body and an unloading device, and the servo triggering anti-drop device body comprises a shaft sleeve, a clamping plate, a counterweight and a servo trigger; the clamping plate, the counterweight and the servo trigger are installed on the shaft sleeve, the shaft sleeve is installed on a fixed shaft, and the clamping plate, the counterweight and the servo trigger surround the outer circular surface of the shaft sleeve and are fixedly welded to the shaft sleeve; the fixed steel beam is provided with a limiting rod with a limiting function, the clamping plate and the servo trigger are close to one side of the guide rail, the servo trigger comprises a support base fixedly welded to the shaft sleeve, a swing rod and an elastic pin, and the swing rod and the elastic pin are installed on the support base. The anti-drop device is applied to an object which vertically lifts and falls, the object is provided with a sliding guide rail, anti-drop blocks are arranged on the guide rail, and when accidental dropping occurs in the lifting and falling process of the object, braking can be achieved within a limited drop difference range to stop dropping.

Description

technical field [0001] The invention relates to the technical field of building construction tools, in particular to an attached lifting scaffold servo-triggered anti-falling device. Background technique [0002] JGJ202-2010 Safety Technical Specifications for Building Construction Tool Scaffold stipulates that the anti-drop device for attached lifting scaffold must be a mechanical automatic device, and it is strictly forbidden to use manual devices that must be reassembled every time they are lifted. The braking distance is not greater than 80mm. [0003] Existing anti-falling devices can be divided into two types from the form of braking, one is friction braking, and the other is jamming braking. The advantage of friction braking is that the braking impact is small, and the advantage of jamming braking is that the braking distance is short. The specification has clear requirements on the braking distance, the friction anti-falling device has been basically eliminated, an...

AI Technical Summary

Problems solved by technology

The position of the lower anti-fall point is close to the rotation center, resulting in jamming; the upper anti-fall point is far away from the rotation center, resulting in no triggering
