Common multi-story parking spaces include parking space frames, storage racks, power devices and lifting mechanisms.

[0019] like Figure 2As shown, the lifting device is used to lift the vehicle, and its power comes from the oil pressure output by the oil pump 240. It adopts the method of synchronously combining the hydraulic cylinder 410 and the lifting group.

As far as the present embodiment is concerned, sprockets and chains are preferably used.

[0020] like Figure 3 As shown, the hydraulic control circuit is used to control the lifting and lowering actions of the lifting device, and the hydraulic control circuit includes valve 1 310, valve 2 320, valve 3 330, valve 4 340, accumulator 350, oil tank 360 and pressure gauge 370; valve 1 310 is a two-position two-way valve, the pressure port of the valve is connected to the oil port of the accumulator 350, and the working port is connected to the rodless chamber of the hydraulic cylinder 410; the valve 2 320 is a two-position two-way valve, the pressure port of the valve is connected to the rodless chamber of the hydraulic cylinder 410 The rod cavity is connected, and the working port is connected with the oil return port of the oil tank 360; the valve three 330 is a one-way valve, the oil inlet of the valve is connected with the oil outlet of the oil pump 240, and the oil outlet is connected with the accumulator 350; the valve four 340 is a relief valve, the oil inlet of the valve is connected with the oil outlet of the oil pump 240, the oil outlet is connected with the oil return port of the oil tank 360, and the oil port of the accumulator 350 is connected with the oil outlet of the oil pump 240; the oil port of the pressure gauge 370 is connected with the oil outlet 240 of the oil pump.

[0021] like Figure 4As shown, the anti-fall device is a safety device used to prevent property and safety accidents caused by abnormal falling. The anti-fall device includes a locking rod 510 hinged to the main frame 110, a pulley six 520 rotatably connected to the main frame 110, a pulley seven 530 rotatably connected to the main frame 110, a pulley eight 540 rotatably connected to the main frame 110, a flexible rope three 550 and a pedal 560; the flexible rope three 550 successively passes around the pulley six 520, the pulley seven 530, and the pulley eight 540, one end of the flexible rope three 550 is fixedly connected to the locking rod 510, and the other end is fixedly connected to the pedal 560; the flexible rope of the device includes ropes, belts, and chains, and the pulleys include sprockets, pulleys, and rope pulleys. In this embodiment, steel wire ropes and rope pulleys are used.

[0022] In addition to the above, in order to ensure the stable and reliable operation of the equipment and for more safety considerations, the design will be designed so that the upper surface of the car blocking roller 230 is higher than the upper surface of the power roller 220; the upper part of the main frame 110 is provided with an adjustable position upper limit block 130 tightened with bolts and an adjustable position lower limit block 140 tightened with bolts. When the car is lifted or lowered to this extreme position, the blocking position of valve 1 310 and valve 2 320 used to control the running direction is triggered, and the lifting or lowering action stops.

[0023] When the vehicle needs to be parked in the upper parking space of the self-climbing three-dimensional parking space, the front-wheel drive vehicle drives into the parking space and the rear-wheel drive vehicle reverses into the parking space. When the vehicle driving wheel 610 is against the vehicle blocking roller 230, the vehicle driving wheel 610 is just pressed on the power roller 220. When the vehicle continues to move, due to the transmission between the power roller 220 and the oil pump 240, the vehicle driving wheel 610 rotates to drive the oil pump 240 to pump oil until the pressure gauge 370 reaches the threshold value, and the power output of the vehicle driving wheel 610 can be stopped. After the engine is turned off and the vehicle is parked according to the normal process, the rearview mirror is folded, the valve 310 is operated, and the accumulator 350 supplies oil to the hydraulic cylinder 410. The vehicle is lifted along with the storage frame 210. When the upper limit block 130 is reached, the upper limit block forces the valve 310 to return to its position, and the vehicle is lifted.

[0024] When it is necessary to lower the vehicle parked on the upper part, the second valve 320 is operated to drain the oil from the hydraulic cylinder 410, and the vehicle descends along with the storage frame 210. When it reaches the position of the lower limit block 140, the limit block forces the second valve 320 to return to its original position. After the vehicle is lowered, the rearview mirror is unfolded. Due to the reverse locking effect of the power roller 220, the vehicle can be started at this time and driven in the reverse direction out of the self-climbing three-dimensional parking space.

[0025] The self-climbing multi-story parking space is equipped with many safety devices, such as an anti-fall device. When a fault occurs in the hydraulic control circuit, the locking rod will support the vehicle to avoid the risk of the vehicle falling or being hit due to abnormal falling.

[0026] The above-described embodiments are only preferred embodiments of the present invention, and are not exhaustive of the feasible implementations of the present invention. For those skilled in the art, any obvious changes made thereto without departing from the principles and spirit of the present invention should be considered to be included in the scope of protection of the claims of the present invention.
