Rotating wheel falling prevention device of attachment type raise scaffold and working method thereof

Abstract

The invention provides a rotating wheel falling prevention device of an attachment type raise scaffold and a working method thereof. The rotating wheel falling prevention device is provided with a guide rail and a guide holder, wherein the guide holder is connected with a guide rail sliding sleeve, the guide rail is provided with spaced cross rods, the guide holder is provided with a rotating wheel which can be meshed with the cross rods in a transmission way, the rotating wheel is provided with a falling prevention clamping wheel, and a shaft seat of the rotating wheel is provided with swing needles by which the rotating wheel falling prevention device of the falling prevention clamping wheel, which reversely and fast rotates, can be braked; the falling prevention swing needles slowly swing and reset and the falling prevention clamping wheel slowly rotates during the slow raise and decline process of the scaffold so as to enable the raising or declining work of a scaffold body to be normally operated; when a scaffold body is suddenly declined, the rotating wheel generates high reverse rotation speed to enable the falling prevention swing needles not to be reset in time, thus the falling prevention swing needles clamp the falling prevention clamping wheel so as to enable the rotating wheel not to continuously reversely rotate, and the rotating wheel clamps the cross rods arranged on the guide rail so as to prevent the scaffold from continuously falling. The invention has the advantages of short braking distance, flexibility, reliability, difficult clamping, relative lower manufacturing accuracy and safe and reliable use.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a runner anti-falling device of an attached lifting scaffold and a working method thereof. Background technique [0002] Building-attached lifting scaffolding is the equipment used in the construction of high-rise and super high-rise buildings. Lifting scaffold mainly includes guide seat, guide rail, frame body, lifting system and control system, etc. In the process of use or operation, some have no anti-fall facilities, and even if some use wheel anti-fall devices, they are generally large in size, or they are prone to failure after a period of use. Once an accident occurs, it is easy to cause a high-altitude fall or Equipment damage accidents bring potential safety hazards. At present, many lifting scaffolds are provided with anti-falling devices. For example, the Chinese patent CN2364133Y "New Swing Needle Runner Anti-falling Device" discloses a swinging nee...
