An acute angle is formed, and the part of next shutdown system is located at support plate 27 and bottom plate 26 is formed by solid space, this
Scheme takes full advantage of the three-dimensional space in parking lot, improves space utilization rate.When needing to pick up the car, again by driving portion
It drives idler wheel 40 to rotate, drives bottom plate 26 to move radially, automobile is removed into parking stall.Control system is controlled by hydraulic control system 37
The piston rod retraction of lifting cylinder, locking cylinder and baffle oil cylinder processed, support plate 27, wheel guard 25 and support rod 32 are returned to
Initial position, support plate 27 are in horizontality again, automobile are sailed out of support plate 27.Then driving portion reversely turns again
It is dynamic, initial position is arrived into the driving of bottom plate 26, avoids impacting the parking of other vehicles.
By setting sliding rail 38 in the technical program, and keep sliding rail 38 parallel with bottom plate 26, when needing movable base plate 26
When, driving portion drives idler wheel 40 to roll, and sliding rail 38 can play the role of guiding, avoid idler wheel 40 during rolling
There is the situation deviated, causes automobile to shake so as to avoid collision between adjacent support plate 27, enhance support plate
The safety of automobile on 27.27 lower end surface of support plate is equipped with multiple buffer parts, specifically, buffer part is rubber pad in this implementation
35, the quantity of rubber pad 35 is two, and two rubber pads 35 are located at the two sides of 27 lower end surface of support plate.Rubber pad 35 can be with
Play buffer function, avoid support plate 27 when rotating down with ground face contact and damage.27 upper surface of support plate is equipped with positioning
Protrusion 31.Positioning protrusion 31 can play positioning action after automobile drives into onto support plate 27.
