A safety anti-fall hook control system and method

Abstract

The invention discloses a safety dropping-preventing hook control system and method. The safety dripping-preventing hook control system comprises a power source relay (1) and at least one safety hook control loop, wherein the safety hook control loops are connected in parallel. Each safety hook control loop comprises a lifting motor contactor (2) and a safety hook coil (3) which are connected in series in sequence, and a power source is connected with the safety hook control loop through the power source relay (1). The safety dropping-preventing hook control system is easy to control, high in reliability and stable in operation, the working time of a safety falling-preventing hook is greatly shortened, and the service life of the safety falling-preventing hook is prolonged.

Description

technical field [0001] The invention relates to a safety anti-fall hook control system and method. Background technique [0002] Mechanical three-dimensional garage is a kind of parking equipment, which is one of the special equipment products. Stacking mechanical, etc. [0003] At present, in the control system of mechanical three-dimensional parking equipment, the action of the safety anti-falling hook is controlled by the electric control contactor of the lifting motor. After the anti-drop hook works normally, turn on the power supply of the lifting motor. This way of working can ensure safety when accessing the car, but the safety anti-falling hook is always open during the lifting process of the motor, but in fact the safety anti-falling hook only needs to move before the vehicle-carrying plate leaves the traversing frame. The operating requirements of the loading plate. The continuous work of the safety anti-drop hook will not only increase the consumption of elect...

AI Technical Summary

Problems solved by technology

The continuous work of the safety anti-drop hook will not only increase the consumption of electric energy, but also greatly reduce its service life, which will bring hidden dangers to the normal operation of the garage

When the number of floors in the garage is not high (such as the second and third floors), the running time of the lifting motor is not long, and the continuous working time of the safety anti-fall hook is not long; but if the number of floors in the garage is high (such as five or six layer or even higher), the continuous working time of the safety anti-fall hook will be greatly extended
