| Mechanical parking system, which is an effective way to solve the parking problems in cities, is widely used in many situations.This paper makes detail analysis and researches of the vertical lifting mechanical parking system. Firstly the general situation and characters of the vertical lifting mechanical parking system is briefly introduced. Secondly the total construction of system is discussed and researched. In the meantime, chain transportation fetching method is chosen to be used in storage-retrieval structure of the parking system, as well as tractor-driven mode is chosen as lifting-driven mode.After design of framework of the parking system is setup, researches on storage-retrieval structure are further. Configuration methods of parking unit and its relative requirements are analyzed. And the detail structure of parking unit and parking board are confirmed coinciding to the GB standard. Functional requirements of storage-retrieval structure and its solving methods are discussed. The design of chain transportation-fetching machine is carried through. Calculations and verifications of parts in chain transportation-fetching machine are also finished.Lifting system is one of core parts in parking system running. Tractor-driven method is used in lifting system and researches on it are preceded. Influential factors of driving ability are analyzed and driving ability is calculated and verified. According to the working condition of lifting system, the analyses and research of lifting system is completed. According to the characters of the vertical lifting mechanical parking system, VVVF motor is selected. Contraposing unsafe factors in system running, over-speed protecting device and bottom-bumping protecting device are put into practice.Besides the construction design of parking system, mathematic models of time consuming and energy consuming for several kinds of system's storage-retrieval strategy are established in accordance with running character of parking system. Emulation to the resolution is carried out using MATLAB software and comparison between these models is made on the base of emulation result. |
