A new type of anti-fall device

Abstract

The invention discloses a novel anti-falling device. The anti-falling device comprises a brake plate, a linear sliding rail A, a linear sliding rail B, a linear sliding block A, a linear sliding blockB, a bolt, a brake clamping piece, a torsion spring, a pulling rope A, a pulling rope B, a thrust bearing and the like. The brake plate of the novel anti-falling device is fixedly mounted in the moving direction of a pulling mechanism. Four through holes are formed in the side surface of a bottom plate, and the bottom plate can be connected with the used pulling mechanism. The thrust bearing is placed at a central hole on the bottom plate, and the torsion spring is placed on the outer circle of the thrust bearing. When falling occurs, stored energy of the torsion spring is released, the brakeclamping piece rotates clockwise along the axis where the bolt is located, a shifting piece on the brake clamping piece makes contact with a clamping groove of the brake plate, and the brake effect is realized. The device is economical, practical, high in feasibility and high in practicability and has the broad market prospect and the good economic benefit.

Description

Technical field [0001] The invention relates to the field of lifting equipment, in particular to a new type of anti-falling device suitable for hoisting goods, protecting personnel safety and avoiding damage to objects. Background technique [0002] Lifting equipment is a device that transports objects from a low place to a high place, and has a wide range of applications in all walks of life. However, in the process of cargo transportation, the lifting equipment often has the risk of the traction rope breaking and causing the cargo to fall. Therefore, a reliable anti-fall device is a part that must be considered in the design of the lifting equipment. [0003] The traditional guiding anti-fall device relies on the friction between the self-locking device and the guide rail to produce a braking effect, which is also called a friction type anti-fall device. This device has special requirements for the material of the guide rail. It adopts a dual guide rail setting and uses a hydrau...

Problems solved by technology

This device has special requirements for the material of the guide rails. It adopts double guide rails, and uses hydraulic cylinders to push out the friction blocks on both sides to squeeze and lower slowly. This makes this structure need to be equipped with an independent hydraulic control system during work, which requires more control procedures for the system. High, once the program is not triggered correctly, it will lead to the failure of the fall prevention device, and the overall equipment cost and maintenance cost are high
