The Key Technology's Research And Development Of Intelligent Large-scale Three-dimensional Parking Equipmeng

At present,stereo parking garage is the effective way to solve the difficulties of parking and crowded traffic.With the gradual increase of the number of buses,we can see the stereo parking garage for small car in our life,the research and development of intelligent large-scale three-dimensional parking equipment is urgent.The paper's engineering background is based on the collaborative project with Chaohu Hanguang parking equipment Co.Ltd.Based on the existing small stereo parking garage to develop intelligent large-scale three-dimensional parking equipment.After the concrete analysis and careful comparison and profound discuss of the current situation and the characteristics of the existing three-dimensional parking garage at home and abroad,finally I choose the lifting and transferring garage as the garage type.The combined transmission of the selection chain and the steel wire rope is used as the transmission mechanism of the garage.After the garage type and transmission mechanism is determined,and then the main structure of intelligent large-scale three-dimensional parking equipment is designed.The design content includes:main frame design,lifting tray design,sliding tray design,design of lifting chain wheel mechanism,design of transmission mechanism and design of locking mechanism.After the completion of the main structure,the strength,stiffness and deflection of the longitudinal beam of the garage are verified.The Lifting and traversing motor models are chosen.Tne method of measuring the center of gravity is used to solve the problem of uneven force of the wire rope.The assembly and lifting mechanism is optimized.Then through the powerful ANSYS analysis software to verify the rationality of the main structure of the garage,and mechanical analysis and modal analysis of the main components are carried out.Because the control system is the core of lift-sliding stereo parking garage,the control requirements and control principle of lift-sliding stereo parking garage are analyzed in detail and the PLC control is selected.The main program and subroutine module are analyzed in the form of flow chart.At last,according to the parking process of lift-sliding stereo parking garage of two layer five parking spaces in the three columns,I compile a set of algorithms with VB language.The simulation software of parking is designed and the vehicle movement is simulated.According to the intelligent large-scale three-dimensional parking equipment,the design of the main frame,the determination of the transmission mechanism,motor selection,the design of control system are described and analyzed in detail in the paper.The results of the analysis and design can provide a reference for the researchers to study the intelligent large-scale stereo parking garage and fill the vacancy of the research on this parking equipment.And this research on the three-dimensional parking garage has great theoretical significance.
