Anti-falling device for attached self-lifting high-altitude sliding mode operation platform and method

Abstract

The invention discloses an anti-falling device for an attached self-lifting high-altitude sliding mode operation platform and a method. The anti-falling device comprises a climbing frame, an operationplatform, a hydraulic system, a brake, a controller and a supporting frame. The operation platform can ascend and descend along the climbing frame. The hydraulic system provides lifting power. The controller is used for controlling the brake. The brake is fixed to the lower end of the operation platform and makes contact with corner posts of the climbing frame. A short feeler lever of the controller senses a descending motion of the operation platform. When the operation platform descends at an overspeed, the feeler lever rapidly rotates to deviate from the original position. Due to the factthat the descending speed is high, the feeler lever cannot return to the original position in time, a cross rod of the climbing frame can drive a long feeler lever to rotate again, and a touch type power switch is communicated through a switch feeler lever and an oil cylinder is capable of returning oil. A wedge block moves upwards under the action of an oil cylinder spring and tightly abuts against a wedge groove inclined face and the corner posts of the climbing frame, and therefore the operation platform is rapidly braked. The anti-falling device for the attached self-lifting high-altitudesliding mode operation platform is ingenious in structure, good in robustness and high in reliability, and can be widely applied to safety guarantee of various high-altitude lifting devices.

Description

technical field [0001] The invention belongs to the field of construction equipment, and in particular relates to a fall prevention device and method for an attached self-elevating high-altitude sliding form operating platform. Background technique [0002] The attached high-altitude self-elevating sliding formwork operation platform is attached to the engineering structure, relying on its own lifting equipment and devices, it can climb or descend layer by layer with the engineering structure, and the construction personnel carry out construction work on the operating platform. The platform operates at a high altitude, so a reliable fall arrest device is needed to ensure the safety of the equipment. Although the lifting device of the equipment itself can ensure the safety of the equipment during normal operation, it is still necessary to consider the safety of the equipment in the event of an accident, that is, a fall prevention device that can be used for an attached self-e...

Problems solved by technology

The disadvantage of this braking method is: due to the limitation of the structural characteristics of the operating platform, the cable device cannot be reasonably arranged, and the applicability of the cable device is not good

[0007] aSingle-point anti-fall ratchet The strength of the brake arm and the ratchet is not high. When the overall size of the anti-fall device is required not to be too large, it is difficult to improve the overall strength of the anti-fall system, thereby affecting the braking effect

[0008] b It is difficult to achieve coordinated braking, because each anti-falling device is independent of each other, and the cooperative braking of the anti-falling device is prone to problems, so that the stress state of the overall structure of the platform after braking is not good, causing structural damage
