Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, the runner anti-falling device of the attached lifting scaffold provided by the embodiment of the present invention includes a guide rail 1 and a guide seat 2, the guide rail 1 is connected to the guide seat 2 with a sliding sleeve, and the guide rail 1 is provided with cross bars at intervals 11. The guide seat 2 is provided with a runner 3 that can be rotated and engaged with the cross bar 11; it also includes an anti-fall card wheel 4 that can rotate with the runner 3, corresponding to the anti-drop card wheel 4 The anti-fall swing needle 5 and the swing needle reset mechanism 6 are provided. This structural design is to control the abnormal rotation of the runner 3 by effectively combining the runner 3, the anti-fall locking wheel 4, the anti-fall swing needle 5 and the swing needle reset mechanism 6, so as to realize the continued fall of the scaffold. Control, since the anti-fall card wheel 4, the anti-fall swing needle 5...

Embodiment 2

[0031] The second embodiment is roughly the same as the first embodiment, except that the reset mechanism 6 of the swing needle is omitted, the anti-fall swing needle 5 is set eccentrically, and the anti-fall is realized by using the action field generated by the eccentric gravity of the anti-fall swing needle 5 Swing needle 5 to reset.

[0032] The present invention also provides a working method of the runner anti-falling device of the attached lifting scaffold involved in Embodiment 1 and Embodiment 2: when the scaffold is slowly lifted, the runner 3 and the spaced cross bar set on the guide rail 1 11 engages and rotates forward slowly; when the scaffold slowly descends, the runner 3 meshes with the spaced cross bar 11 set on the guide rail 1 and reverses slowly; The raised part of the card wheel 4 touches the rear swing head 52 of the anti-falling needle 5, the anti-falling needle 5 swings in the opposite direction, the anti-falling card wheel 4 continues to rotate, and the ...

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...
