The anti-dropping safety device of this attached wall climbing scaffold is made up of catching device, trigger two parts.Catching device be installed in that bearing support is adhered on the frame upper strata of climbing or the leading truck that climbs on, it mainly consists of mount pad, eccentric wheel, elasticity of torsion element etc.Above-mentioned eccentric wheel, elasticity of torsion element composition compress and separating mechanism.Catching device has eccentric wheel, is pressed on the main frame of climbing scaffold Lift Part by elasticity of torsion element on the one hand, can separate with main frame by the flexible connecting member effect that is connected with trigger on the one hand.When lifting force is arranged, the compression elastic element compression, hanging axis descends, and the main frame that drives eccentric wheel and climbing scaffold Lift Part breaks away from, and allows the climbing scaffold lifting; When not having lifting force or lifting force not enough, compression elastic element is in initial position, and eccentric wheel is pressed on the main frame of climbing scaffold Lift Part, prevents to fall.When lifting force disappeared or be lower than setting value, eccentric wheel rotated around dead axle, can be pressed on by the effect of elasticity of torsion element on the main frame of climbing scaffold Lift Part, with the climbing scaffold stop.When lifting force reaches setting value, overcome the active force of elasticity of torsion element, eccentric wheel breaks away from around the main frame of dead axle rotation with the climbing scaffold Lift Part, allows the climbing scaffold lifting.The eccentric wheel outer rim is a non-smooth surface.
Bearing position adheres in the lower floor that trigger is installed in climbing scaffold.Form by trigger seat, compression elastic element, hanging axis etc.Hanging axis is bearing on the trigger seat by the flexible member that contracts, and the upper end is connected with the catching device eccentric wheel by flexible connecting member, and the lower end is as climbing scaffold lifting appliance supporting-point.The hanging axis of trigger is supported by compression elastic element, and an end links with the catching device eccentric wheel is flexible, and an end hangs or attachment point as lifting appliance.Above-mentioned hanging axis supports by compression elastic element, constitutes the trigger mechanism related with lifting force.
Promote or the decline state, lifting appliance produces lifting force, produces downward pulling force simultaneously in the hanging axis lower end, the compression of trigger flexible member, hanging axis descends, and rotates by flexible connecting member pulling eccentric wheel, break away from the main frame of climbing scaffold Lift Part, climbing scaffold can lifting.
The utility model is compared with other existing catching device, and is simple in structure, in light weight, trigger rapidly, and the effect stroke is short, and anti-fall effect is obvious.Since in light weight, moving when making things convenient for climbing scaffold to change layer especially; Its anti-fall effect and lifting force interrelate, and can prevent effectively that the people from being the falling accident that maloperation causes; Its operating distance is short, and is safe and reliable.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural principle schematic diagram of the present invention.
Reference numeral: bearing support, 11-pull bar, 12-catching device shell adhere in the main frame of 1-catching device seat, 2-climbing scaffold Lift Part, 3-eccentric wheel, 4-elasticity of torsion element, 5-flexible connecting member, 6-upper layer bracket, 7-hanging axis, 8-trigger seat, 9-compression elastic element, the 10-frame lower floor of climbing.
The specific embodiment
Embodiment is referring to shown in Figure 1, and the anti-dropping safety device of this attached wall climbing scaffold comprises the catching device that is fixedly connected on the upper layer bracket 6 and is fixedly connected on the frame lower floor of climbing and adheres to trigger on the bearing support 10.Upper layer bracket 6 is adhered to bearing support or the leading truck that climbs for the frame upper strata of climbing.
The catching device seat 1 of described catching device be positioned at that bearing support is adhered on the frame upper strata of climbing or the leading truck that climbs on, fixed eccentric 3 and elasticity of torsion element 4 on the catching device seat 1, elasticity of torsion element 4 is clockwork spring, wind spring or torsion spring.Eccentric wheel 3 is coaxial with elasticity of torsion element 4, and an end of elasticity of torsion element 4 is connected with eccentric wheel 3, the other end is connected with catching device seat 1 again, and eccentric wheel 3 is a non slip surface with the external surface in the zone of main frame 2 CONTACT WITH FRICTION of climbing scaffold Lift Part, and non slip surface has serrate slot or flower shape groove.Eccentric wheel 3 axle center to the distance between the main frame 2 of climbing scaffold Lift Part less than eccentric wheel 3 axle center to its distance from axle center distal-most end edge, the main frame 2 of climbing scaffold Lift Part passes from catching device shell 12.
Described trigger is fixedly connected on the frame lower floor of climbing by trigger seat 8 and adheres on the bearing support 10, and the lower end of compression elastic element 9 is connected the bottom of trigger seat 8, and the upper end of compression elastic element 9 connects a hanging axis 7.Compression elastic element 9 is spring, bourdon tube or elastic bellows.
