Technical Field

The invention relates to a mechanical parking device, in particular to a multilayer multi-ring disc type three-dimensional parking garage.

Background

The urbanization process is accelerated continuously, the living standard of the resident materials is improved continuously, and the automobile consumption is increased rapidly. According to data of a public security traffic administration part, the number of vehicles in China reaches 2.35 hundred million by 9 months in 2018. Wherein the automobile inventory of Beijing has exceeded 800 ten thousand, and the number of automobiles in 10 large and medium cities, such as Tianjin, Chengdu, Shenzhen, Shanghai, Guangzhou, Suzhou, Hangzhou, Changsha, Wuhan, etc., has exceeded 300 ten thousand. Under the background and pressure of increasing automobile holding capacity, the increasingly tense urban parking space resources are brought, and according to data issued by relevant departments, the average ratio of the automobile holding capacity to the parking space number in a large city in China is about 1: 0.7, the proportion of small and medium-sized cities is about 1: 0.5; the ratio of the automobile holding capacity to the number of parking spaces in western developed countries with better traffic conditions is about 1: 1.3. therefore, the number of the existing parking spaces in China is far lower than the actual demand, the number of gaps is estimated to be over 7200 and is more than ten thousand by conservative estimation, and the number of the gaps is continuously enlarged along with the increase of the automobile holding capacity.

In the face of the difficult parking problem caused by the increasing automobile holding amount, the representative intelligent three-dimensional parking device has attracted extensive attention of all social circles: the parking device comprises a vertical circulation type mechanical parking device, a lifting and transverse movement type mechanical parking device, a plane movement type mechanical parking device, a simple lifting type mechanical parking device, a vertical lifting type mechanical parking device, a roadway stacking type mechanical parking device, a multi-layer circulation type mechanical parking device and the like, and an automobile lifter and an automobile rotating disc which are matched with the large intelligent three-dimensional parking devices.

The rotary disc type three-dimensional parking device is very suitable for multi-layer design, and can effectively utilize the ground space by adopting annular distribution of each parking space. For example, a "rotary disc type stereo parking system" disclosed in chinese patent No. zl201521106525.x, the scheme thereof is: the inside of the circular frame is provided with m layers of disc-shaped parking garages along the inner side wall, and the internal space of the m layers of disc-shaped parking garages is provided with four elevators; each layer of parking garage is provided with 1 horizontal rotating disk, and the horizontal rotating disks move along a circular guide rail through rollers on the lower surfaces of the horizontal rotating disks; n parking spaces are uniformly arranged on the upper surface of the horizontal rotating disc along the circumferential direction; a control unit: the vehicle access instruction output end of the keyboard input unit is connected with the vehicle access instruction input end of the controller; the command output ends of the controllers are respectively connected with the command input ends of the m servo motors, and the servo motor of the target parking space layer drives the target parking space of the horizontal rotating disc of the layer to rotate to a certain elevator position; the controller controls the elevator to rise to the designated floor height, and the car is taken out and stored. As another example, the chinese patent application No. 201810108588.0 discloses a "carousel-type stereo garage," which includes a lower parking plate and an upper parking plate that can rotate under the drive of a rotary driving device, wherein a plurality of parking spaces are provided on the lower parking plate and the upper parking plate, a lifting device that can lift the vehicle is provided in the middle of the lower parking plate, and a horizontal conveying device that can allow the vehicle to enter and leave the parking spaces is provided on the upper parking plate and the lifting device. The stereo parking garage and the parking system thereof all adopt the rotary disk type stereo parking device, and for the rotary disk type stereo parking device, the rotary driving design of the horizontal rotary disk is the core part of the parking device, thus directly influencing the working stability and the practicability of the rotary disk type stereo parking device. The horizontal rotary table of the existing rotary disc type three-dimensional parking device mostly adopts a gear driving structure in the patent application number 201810108588.0, namely, a gear ring is arranged on the horizontal rotary table, a driving gear arranged on an output shaft of a motor is used for driving the gear ring to rotate, the driving mode needs the gear ring with a very large design size, the gear ring is difficult to process in actual production, on one hand, the gear ring is oversize, no corresponding processing equipment is used for processing, in addition, the processing precision is difficult to guarantee due to the oversize gear ring size, and the stable transmission of the driving gear and the gear ring is difficult to guarantee. In addition, due to the limitation of the driving structure of the rotary disc type three-dimensional parking device, the existing rotary disc type three-dimensional parking device can only be designed with one circle of parking spaces basically, so that more parking spaces cannot be arranged in the same space, the ground space is difficult to reasonably utilize, and the advantage of multilayer arrangement of the rotary disc type three-dimensional parking device cannot be fully played.

Based on the above problems of the existing rotary disk type three-dimensional parking device, it is necessary to design a novel driving mechanism suitable for large-size horizontal turntables so as to meet the rotary driving requirement of the rotary disk type three-dimensional parking device and improve the arrangement flexibility and the practicability of the multilayer multi-circle horizontal turntables in the rotary disk type three-dimensional parking device. In addition, with the popularization of new energy automobiles and the frequent spontaneous combustion accidents of the new energy automobiles, the stereoscopic parking device has dense parking of vehicles, and the spontaneous combustion and ignition accidents of the vehicles are important problems to be solved urgently.
