Specifically, as shown in fig. 4, the vehicle carrying tray of the parking apparatus is composed of a vehicle carrying tray frame and a vehicle plate laid on the frame. The tray frame is comprised of side beams 1063 and connecting channels 1062. The side beam 1063 is formed by bending a 4mm steel plate, a plurality of reinforcing rib plates 1064 are welded on the side beam, and the side beam has good strength and rigidity, in practical application, a plurality of vehicle plates are assembled into a whole, so that the side beam has good stability, the probability that a wheel acts on one vehicle carrying plate is not high, but the single vehicle plate is still independent, and the maximum theoretical load is added for strength check. In practical application, the vehicle plate is a pure bending beam with two fixed ends and a movable hinged support with one fixed end and the other movable end, but the vehicle plate is simplified into the pure bending beam in calculation, and is relatively conservative compared with the practical situation.

The specific truck plate stress and restraint diagram is shown in fig. 5, and if the vehicle weight is 2000kg, the vehicle width direction wheel is 1600mm, and the front wheel bears 60% of the total vehicle weight, then the following can be calculated:

the intensity calculation formula of the vehicle carrying disc is as follows;

p1 ═ P2 ═ (vehicle weight 0.6)/(2 × 9.8 (N));

P1＝P2＝2000x0.6/2x9.8(N)＝5880N

calculating a support reaction force according to static balance;

RA＝RB＝(P1+P2)/2。

P1＝P2＝2000x0.6/2x9.8(N)＝5880N

the bending moment diagram of the beam is shown in fig. 6;

Mmax＝MC＝MD＝263.1kN·m

from the map it can be determined that the beam has a hazardous cross-section at points D and C.

The cross-sectional shape of the vehicle plate is shown in fig. 6, and according to the cross-sectional shape, with the aid of professional software, the relevant geometric characteristics of the cross-section can be calculated as follows:

Iz＝2.43x10-6m⁴

y1＝33.8x10^-3m

according to the bending moment value of the section and the distance between the edge point and the neutral axis, the lower edge of the C section can be judged as the maximum stress point.

Section C:

t＝Mmaxy1/Iz＝263.1x103x33.8x10^-3/(2.43x10^-6)

＝36.6MPa

and (4) looking up a table by taking i as 3 as a design safety coefficient to obtain the allowable tensile stress of the Q235 steel as follows:

[]＝s/i＝235MPa/3＝78.3MPa

by comparison: t < [ ]

Therefore, the strength of the vehicle carrying plate meets the design requirement.

As a preferred scheme, the working method of the seven-layer lifting longitudinal movement parking equipment comprises the following steps:

step 1, stopping a vehicle on a vehicle carrying tray by a driver, starting equipment, selecting a set parking space, reserving a vacant space in the uppermost layer and the rest layers, and providing a path for carrying the vehicle carrying tray suitable for stopping the vehicle, assuming that the set parking space is three layers or four cases;

step 2, when the vehicle is parked on the vehicle carrying tray, the lifting driving device 2 drives the vehicle carrying tray to work, the parking places 14 and 24 are vacant, and the vehicle needs to be parked in the parking place 33;

3, transversely moving the vehicle carrying plate at the lower part of the parking space to vacate a downlink channel;

step 4, the vehicle carrying disc of the parking place 13 and the vehicle carrying disc of the parking place 23 move rightwards by one parking place and respectively enter the parking places 14 and 24;

and 5, the vehicle carrying disc on the parking space 33 can descend to move to the lower layer for storing the vehicles, the vehicles are stopped on the vehicle carrying disc, the vehicles do ascending and descending actions to return to the original parking space, and the vehicles are stored and taken next time.

Further, the method comprises the following steps of; taking a 16# parking space as an example, the 13, 10, 7, 4 and 1 parking spaces are transferred to the left vacant parking space by using a transverse transmission system of a transverse frame; the 16# parking space lowers the vehicle carrying plate to the ground through the lifting system, and vehicles are directly driven out of the vehicle carrying plate.

Further, the method comprises the following steps of; taking a 12# parking space as an example, the 9, 6 and 3 parking spaces are transferred to the left vacant parking space by utilizing a transverse transmission system of a transverse frame; the 12# parking space lowers the vehicle carrying plate to the ground through the lifting system, and vehicles are directly driven out of the vehicle carrying plate
