Description

Device for accessing vehicle in drawer type three-dimensional parking lot

Technical Field

The invention relates to the technical field of intelligent parking, in particular to a device for accessing a vehicle in a drawer type three-dimensional parking lot.

Background

At present, there are several common three-dimensional intelligent parking lots:

a lifting and transverse moving type stereo garage is a mechanical parking device which is most widely applied. When a certain parking space needs to be used for storing and taking the vehicles, all parking spaces between the lower part of the parking space and the vacant positions move transversely to the vacant positions by the distance of one parking space in the direction of the vacant positions, a lifting channel is formed below the parking space, at the moment, the parking space can be freely lifted, and when the parking space is lowered to the ground, the vehicles can be driven in or out. However, each set of equipment has to be provided with at least one empty parking space, and the car taking and storing process does not have the function of preventing the car from falling obliquely, so that the safety is poor.

The vertical circulating type stereo garage is the most representative of the circulating type stereo garages. The stereo garage generally refers to parking equipment with a carrier which circularly moves in a vertical working plane. Generally, a large circulation device is installed in a main building, and only a small circulation device is installed outside the building. The method for installing the equipment has the advantages of reducing land use area, having certain stability and being convenient to operate, but has the problem of higher energy consumption. The horizontal circulating stereo garage can be flexibly arranged, the land use area is reduced, the improvement of the land use ratio is enhanced, the exhaust emission is reduced, but the defect in beauty is that large energy is consumed for storing vehicles.

The elevator type stereo garage is also called a tower type stereo garage, the number of the layers is higher, generally exceeds six layers, and mature elevator technology can be used for enabling an automobile to rapidly ascend and descend to a specified floor. The parking stall of elevator formula stereo garage is fixed, and the depositing of car utilizes distinctive lateral shifting device to realize the access of car before moving to the parking stall through elevator system. The whole garage is fully controlled by a computer, automatically operated and displayed, no person enters the garage area, and the artificial automobile can be prevented from being lost and damaged. The elevator type stereo garage has high land utilization rate. If the turnplate is arranged in the garage, the automobile can turn around automatically, the time for getting in and out of the garage is shortened, and the automobile can be rapidly stored and taken. The garage can be built on narrow land, and can be built by attaching to a building or independently. The elevator type stereo garage can be arranged on the ground, semi-underground or underground.

Roadway stacking type stereo garage. The vehicle transportation device is a roadway stacker, and vehicles driven into the roadway stacker can move in two dimensions simultaneously, quickly reach a specified parking space, and then are parked into the parking space by using the access mechanism. This garage is equivalent to the warehouse, appears in the U.S. at the earliest, is applicable to several hundreds or even thousands of large-scale automatic garage parking, and this kind of garage mainly is applicable to large-scale intensive formula parking, and equipment structure is complicated, and power cord and communication line along with the stacker removal break down easily, and the practicality is relatively poor.

AGV (automated Guided vehicle) is an English acronym for an automated Guided vehicle. It is an automatic, unmanned and battery-powered handling device equipped with a non-contact guiding device and an independent addressing system. In the related fields of logistics production and the like, an operator does not need to drive a transport vehicle in person, but can utilize a remote computer to control the transport vehicle or set a planning line of the AGV action in other modes, such as an electromagnetic track, a magnetic strip track and the like, and then the AGV and an upper computer move after analysis according to feedback information.

The device provided by the invention can adapt to the special environment in the multistory parking garage by using the AGV car related technology and carrying out certain modification on the AGV car related technology, so that the multistory parking garage can utilize the space to the maximum extent, has outstanding land saving advantages, and has the floor area of 1/3-1/20 of the parking garage with the same scale. The device can also be used for better unmanned intelligent management, the working efficiency of the parking lot can be improved by using the device to store and take the vehicle, the management of the parking lot is more intelligent and convenient, the troubles of arrangement and wiring of various motor cables in the parking lot are reduced, the cost is saved, and the space utilization rate is improved. The three-dimensional parking lot can be used on large-area land, and a certain amount of parking berths can be built by utilizing narrow space.
