A mechanical fall prevention device for a three-dimensional garage

Abstract

The invention relates to a mechanical fall prevention device for a three-dimensional garage. The device is mainly used for a lifting type three-dimensional garage and comprises fall prevention assemblies, steel wire ropes, adjusting rods, oblique spacers, butterfly nuts and hanging rings. When a vehicle carrying plate is located on an upper limitation position and is in the rising and falling process, the steel wire ropes are in a tensioned state, and hook bodies of the upper ends of fall prevention hooks are kept in a vertical state and are away from the hanging rings by the distance which at least enables the hook bodies not to collide against the hanging rings. If lifting chains of the three-dimensional garage are fractured, the steel wire ropes are loosened, the fall prevention hooks rotate towards the directions of vertical columns of the three-dimensional garage under the effect of torsion springs to enable the hook bodies of the upper portions of the fall prevention hooks to be hooked on the hanging rings, and thus falling of the vehicle carrying plate is prevented. According to the mechanical fall prevention device for the three-dimensional garage, the structure is simple, using is convenient and reliable, accidental falling when the vehicle carrying plate is motionless in a high position can be prevented, and accidental falling of the vehicle carrying plate in the rising and falling process can further be prevented.

Description

technical field [0001] The invention relates to an anti-falling device, in particular to a mechanical anti-falling device suitable for a three-dimensional garage. Background technique [0002] The anti-fall device is a necessary safety component of the three-dimensional garage, which is mainly used to prevent the accidental fall of the vehicle-carrying plate. At present, the anti-falling device of the three-dimensional garage is mainly used to prevent the accidental fall of the vehicle-carrying plate when it is static at a high position, and cannot prevent the accidental fall of the vehicle-carrying plate during the lifting process. Existing anti-falling devices can be divided into three types: mechanical type, electromagnet type and electromechanical hybrid type. Among them, the mechanical type includes a cross-type anti-drop device and a triangular stop type anti-drop device. The advantage of this type of device is that it is low in price and does not have any electrical...

AI Technical Summary

Problems solved by technology

The advantage of this type of device is that it is low in price and does not have any electrical devices, that is, it does not need electromagnets or micro switches, and there are fewer potential faults. The maintenance quality requirements are relatively strict, and the mechanism will be deformed during use, which may cause the opening device on the vehicle-carrying plate to fail to open the hook normally, resulting in the danger of a corner of the vehicle-carrying plate being caught. Large potential safety hazards, while electromagnet and electromechanical hybrid structures are complex and costly
