Falling prevention device of carrying trolley and three-dimensional parking garage

Abstract

The invention provides a falling prevention device of a carrying trolley, which comprises a stop lever, a first limiting switch, a second limiting switch, a linear motor, a base and a motor rack. The stop lever is connected with the linear motor via the motor rack, the motor rack is driven by the linear motor to be capable of driving the stop lever to stretch and retract in a reciprocating manner, and the movement range of the stop lever is limited between the first limiting switch and the second limiting switch. The invention further provides a three-dimensional parking garage. Compared with the prior art, the falling prevention device of the carrying trolley effectively reduces risks caused by instability of electrical elements via a mechanical limiting mechanism. Besides, the linear motor drives the motor rack to be connected with the retractable stop lever, even if the retractable stop lever is collided with the carrying trolley, the motor cannot be damaged, the carrying trolley can continue being used after the stop lever is replaced directly, and maintenance cost is lowered effectively. In addition, compared with the prior art, the falling prevention device of the carrying trolley and the three-dimensional parking garage are simple in structure, convenient in installation, low in cost and safe and reliable in use.

Description

technical field [0001] The invention belongs to a safety device for automatic parking equipment, and in particular relates to an anti-falling device for a transport trolley used in a three-dimensional garage and a three-dimensional parking garage using the anti-falling device for a transport trolley. Background technique [0002] In the current three-dimensional parking garages for storage, the protection of the transport trolley is usually realized by setting up electrical components. After the signal triggers the photoelectric detection device, the transport trolley moves in translation and enters the lift car; if the lift car does not touch the detection photoelectric signal and thus does not trigger the photoelectric detection device, the transport trolley cannot move in translation to the position of the lift shaft. The above method has the following risks: when the transport trolley is in the process of translation operation, if the calculation of the number of columns...

AI Technical Summary

Problems solved by technology

The above method has the following risks: when the transport trolley is in the process of translation operation, if the calculation of the number of columns in the system is wrong at this time, the situation that the transport trolley has moved to the position of the elevator shaft before the elevator car stops at the designated position will occur. In this way, the transport trolley will fall into the hoistway, and the vehicles carried on the transport trolley will also be smashed, and the automatic parking equipment will be damaged.
