Description

Double-wheel synchronous driving multi-ring disc type three-dimensional parking device

Technical Field

The invention relates to a mechanical parking device, in particular to a multi-ring disc type three-dimensional parking device driven by two wheels synchronously.

Background

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.

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.

Therefore, based on the above problems of the existing rotary disc type three-dimensional parking device, it is necessary to design a novel driving mechanism suitable for large-sized horizontal rotary discs, so as to meet the rotary driving requirements of the rotary disc type three-dimensional parking device and improve the arrangement flexibility and practicability of a plurality of circles of horizontal rotary discs in the rotary disc type three-dimensional parking device. Meanwhile, with the popularization of new energy automobiles and the frequent spontaneous combustion accidents of the new energy automobiles, the stereoscopic parking device has dense vehicle parking, and the spontaneous combustion and ignition accidents of the vehicles are key problems to be solved urgently.
