[Abstract]:The development of urban underground parking space is an effective method to solve the contradiction between parking demand and urban planning, urban management and traffic management. The existing stereoscopic garage has many defects, such as large area, high energy consumption, high noise, long time for storing and storing vehicles, and it is not easy to combine to form a garage group, while the deep shaft type stereoscopic garage is a kind of electromechanical and hydraulic integrated stereoscopic parking equipment built underground. It has the comparative advantage of high land utilization ratio, large storage capacity ratio, low energy consumption, low noise, high intelligence, and can be combined into garage group according to local conditions, which is the development direction of mechanical stereoscopic garage. Based on the intelligent PSC8CK-4ZT deep well garage which is suitable for the parking of XG C car, the function principle of the garage is expounded, and the comparative advantages of single library and storage group are demonstrated. This paper analyzes the problems existing in the design, manufacture, use and maintenance of this type of garage mechanical system and its parts and components, and makes technical improvements by using modern design analysis method and concurrent engineering theory. Aiming at the lifting power system, in order to meet the requirement of maximum parking brake torque when heavy load failure, the selection, optimization and improvement design of hydraulic motor and flange bolt group are carried out to enhance the safety of lifting power system, and to use transplant to create, Combination of innovation theory, designed based on friction anti-loosening form of the top anti-loosening method, based on mechanical anti-loosening form of multi-bolt anti-loosening method to improve the reliability of the garage, based on transplantation innovation theory, A disconnected torque spring automatic clearance canceling synchronous device is designed and manufactured, which eliminates the phenomenon of "stuffing" caused by bias load, and improves the safety of operation. Through finite element statics analysis, the ratio of performance to weight of the synchronous device is improved. Based on the concurrent engineering theory, the high precision gear pitch control gauge is designed, and the high precision magnetic right-angle leveler is selected, which greatly reduces the difficulty of rack manufacture, installation and maintenance. In view of the poor control precision of the hydraulic lifting device originally designed for lifting and traversing system, three kinds of synchronous schemes of lifting device are redesigned to solve the problem of lifting out of synchronization of four cylinders, which effectively ensures the synchronization accuracy and smooth operation of lifting action. Based on the fact that the design of mechanical system of garage has gradually formed a variety of schemes composed of different parts and components, in order to fully demonstrate the characteristic advantages of deep shaft type stereoscopic garage and promote its application, this paper adopts the system engineering analysis method. The multi-factor analysis and evaluation model is established by considering the technical characteristics, operation characteristics, economy and sociality of each system or assembly, and the weighting coefficient of each evaluation objective is determined by using the method of mandatory judgment. Organized design and manufacturing engineers, on-site construction personnel, operation and maintenance personnel, developers and user representatives, and so on, to each combination of the program score, through the evaluation model solution, select all aspects of the comprehensive performance of the optimal scheme, So that the mechanical system in processing, assembly, operation, maintenance, cost control and green environmental protection and other aspects to achieve harmony and unity, for the value of deep shaft garage optimization and social promotion of the analysis and research provides a basis. In order to ensure the efficient and orderly work of multi-factor analysis and evaluation, based on the MATLAB R2010b platform, this paper designs and develops a comprehensive evaluation software for the mechanical system of the deep shaft type stereoscopic garage, which includes the setting of the integrated weighting coefficient, the score of the combined scheme and the total evaluation of the mechanical system. Data maintenance and other module functions to achieve the evaluation process of information.
