Underground rotary garage and center shaft thereof

Abstract

The invention discloses an underground rotary garage and a center shaft thereof. The underground rotary garage is characterized in that the center shaft is a hollow shaft, and is fixed on a bearing column; a track or a running limiting device is arranged around the center shaft; circular loading platforms are connected through safety protection devices, and are uniformly arranged on the track or the running limiting device; the circular loading platforms arrive at a brake lifting area through a shortest path; the track or the running limiting device arranged around the center shaft is used for limiting the running paths of the circular loading platforms in order that the circular loading platforms can only rotate about the center shaft at a specified position; the circular loading platforms which are connected through the safety protection devices are combined into a firm circular ring body; the circular loading platforms in the circular ring body cannot move upwards, downwards, leftwards and rightwards, and can only rotate about the center shaft of the underground rotary garage stably and orderly.

Description

technical field [0001] The invention relates to a parking device, in particular to an underground rotary garage and its central axis. Background technique [0002] With the continuous and rapid development of my country's national economy, especially cars entering the family, the car ownership rate is rising rapidly, and the problem of parking in cities is getting worse. On the one hand, the exhaust gas emitted by long-term low-speed and idling vehicles has brought serious pollution to the urban environment. Therefore, how to reasonably solve the parking problem is imminent. As an effective measure to solve urban parking difficulties - mechanical three-dimensional parking equipment, with its unique advantages, has become an effective means to alleviate urban parking difficulties, has been widely used, and has formed a new industry. [0003] my country's existing mechanical three-dimensional parking equipment is widely used mainly in four types of garages such as lifting and...

Problems solved by technology

However, there are still various defects in "a circular vehicle-carrying platform of an underground rotary garage and its use method". For example, the underground rotary garage is fixed on the central axis and connected with the central axis, and the circular vehicle-carrying platform of the underground rotary garage is parked. The vehicles in the car are unbalanced, and when there are more cars parked on one side and fewer cars parked on the other side, a large external force couple moment will be generated, which will cause a safety hazard to the shaft of the underground rotary garage; therefore, it is necessary to increase the diameter of the shaft and use Steel and other materials with high shear strength can be used to make the shaft to improve the shear resistance of the shaft; for example, a medium-sized underground carousel that can park 30-50 cars needs a diameter of more than ten meters, and the diameter of its central shaft will be several meters. A steel shaft with such a large diameter is not only expensive, but also the corresponding bearings are difficult to process...
