Description

Two-column lifting type circular tower garage parking equipment and vehicle parking method

Technical Field

The invention belongs to the technical field of three-dimensional parking garages, and particularly relates to two-column lifting type circular tower garage parking equipment and a vehicle lifting and turning method.

Background

The stereo garage is a stereo parking device, does not need a driver to drive and dispatch vehicles, and can automatically park the vehicles at specific positions of specific high floors by means of devices in the garage. The three-dimensional parking circular tower garage has extremely high space utilization rate, and the static traffic jam problem of areas such as business circles, hospitals, tourist attractions and the like is relieved to a great extent. The existing three-dimensional parking circular tower warehouse is basically in a four-column lifting or eight-column lifting mode, and some manufacturers adopt an integral rotation mode of a lifter.

When four columns or eight columns are adopted for lifting, a lifting mechanism is arranged at the top of the whole steel structure, and the lift function of the lift car at the whole middle part can be realized. When the elevator is lifted, the elevator car does not rotate, and after the elevator reaches a specified floor, a rotation mechanism arranged on an intermediate car platform rotates the elevator car to a specified parking space position. Because each upright post is provided with a hanging point when four or eight posts are lifted, the lift car is required to be connected with each hanging point independently, so that the whole size of the lift car is larger. The middle car can only transport one car at a time, so that the space utilization rate of the middle car is low, and the occupied area is large. And the floor area of the upright post of the lifter is large, so that the relative construction cost is increased, and particularly, the cost is increased more when the upright post of the lifter is of a civil engineering structure.

When the whole rotation mode of the lifter is adopted, the rotation mechanism is arranged at the bottom of the whole lifter, the lifting device independent of the rotation mechanism can be arranged at the bottom of the lifter or at the top of the lifter, and the rotation mechanism at the bottom drives the lifter upright post and the lifting lift car to integrally rotate when rotating. Elevators are generally of the type in which four columns are lifted. When the elevator rotates, due to inertia, there is a time difference when the four upright posts start or stop rotating, so that a guiding device must be installed. The guiding device is generally used by matching a guiding wheel around the periphery of the lifter with a guiding steel piece arranged on the upright posts, and the principle is that the moment of starting or stopping rotation of the four upright posts is unified by limiting the guiding wheel by the steel piece, so that the upright posts are prevented from twisting. The elevator guiding device is generally arranged, the guiding device can be arranged only at the top when the number of layers is less than or equal to three, and a group of guiding devices is generally arranged every two layers when the number of layers is more than three. On the other hand, because the lift car is arranged in the middle of four upright posts, the top end of the upright post can be bent towards the center of the car in the lifting process, the upright post of the lifter is easy to deform and twist after long-time running, and the guide wheels do not move smoothly. The four-column or eight-column lifter and the integral rotary lifter are in two different structural forms, and the upright post of the four-column or eight-column lifter is generally arranged near a parking space and positioned at the edge of the integral lifting channel; the integral rotary elevator is generally disposed in the middle of the hoistway.
