[0056] like Figures 1 to 17 As shown, this embodiment proposes a lifting-type three-dimensional parking device, including a support assembly 11, a drive assembly 12, and a vehicle-carrying plate assembly.

[0057] The support assembly 11 has a column 13 and a motor beam 14. The two ends of the motor beam 14 are fixed to the ground by the column 13. Each column 13 has a guide structure arranged in the vertical direction. The guide structure is used for sliding installation of the vehicle platform assembly.

[0058] The drive assembly 12 includes a transmission chain assembly, a guide structure for mounting the transmission chain assembly, and the transmission chain assembly for controlling the movement of the vehicle platform assembly in the vertical direction.

[0059] There are two vehicle-carrying plate assemblies, namely the top-layer vehicle-carrying plate assembly 15 and the middle-layer vehicle-carrying plate assembly 16;

[0060] The guide structure includes a first guide groove 17 and a second guide groove 18. The first guide groove 17 is used for sliding installation of the top layer vehicle plate assembly 15, and the second guide groove 18 is used for sliding installation of the middle layer vehicle plate assembly 16.

[0061] This solution adds two layers of parking spaces by setting up a top-level vehicle carrier assembly 15 and a middle-level vehicle carrier assembly 16. This enables three-level parking on the same ground surface, effectively increasing parking capacity. Furthermore, this parking equipment can be arranged in multiple rows side-by-side or in multiple rows longitudinally, allowing for dense parking of vehicles in confined spaces. This solution offers advantages such as low cost, adaptability to complex application sites, and ease of operation.

[0062] Furthermore, it also includes an electrical control system for controlling the operation of the top-layer vehicle platform assembly 15 and the intermediate-layer vehicle platform assembly 16.

[0063] Furthermore, the lifting-type multi-level parking system in this solution has the advantage of being able to be continuously arranged in the front-back and left-right directions, which broadens the scope of equipment requirements.

[0064] Furthermore, the drive assembly 12 includes a first motor 19 and a second motor 20;

[0065] The drive assembly 12 has two sets of transmission chains, namely the first transmission chain 21 and the second transmission chain 22.

[0066] The first transmission chain 21 is used to drive the top layer vehicle platform assembly 15 to move vertically, and the second transmission chain 22 is used to drive the middle layer vehicle platform assembly 16 to move vertically.

[0067] In one embodiment of this invention, a first drive shaft 23 and a second drive shaft 24 are rotatably mounted on the motor beam 14.

[0071] The first drive shaft 23 has a first driven sprocket 25 at each end; there are two first drive chains 21, which are located at both ends of the first drive shaft 23, and the installation method of the first drive chains 21 is as follows:

[0072] One end of the first drive chain 21 is fixed to the top-level vehicle platform assembly 15, and the other end of the first drive chain 21 passes through the first driven sprocket 25 and the first counterweight wheel 32 and is mounted on the column 13. The first drive chain 21 is meshed with the first driven sprocket 25 and the first counterweight wheel 32 respectively, and the first counterweight wheel 32 is located below the first driven sprocket 25.

[0073] When the first motor 19 drives the top-level vehicle platform assembly 15 to move upward, the first counterweight 31 and the first counterweight wheel 32 move downward under their own weight to keep the chain taut. Conversely, when the first motor 19 drives the top-level vehicle platform assembly 15 to move downward, the first counterweight 31 and the first counterweight wheel 32 are pulled upward.

[0074] As one embodiment of this example, the top-level vehicle platform assembly 15 includes a first vehicle platform 33 and a first boom 34. The first boom 34 is fixed to both ends of the first vehicle platform 33 along its width direction. A first lifting guide wheel 35 is rotatably mounted on the first boom 34 through a first lifting guide wheel mounting assembly. The first lifting guide wheel 35 is disposed in the first guide groove 17.

By rotating the angle of the first adjusting bushing 46, the eccentric position of the first lifting guide wheel eccentric shaft 45 is changed, which is used to adjust the relative position between the first lifting guide wheel 35 and the first guide groove 17. It is also used to adjust the tilt angle of the first vehicle platform 33 so as to ensure stable parking of the vehicle.

[0078] The first lifting guide wheel mounting assemblies are arranged in pairs, located at the upper and lower ends of the first boom 34, respectively.

[0079] The first flat key is on the eccentric shaft 45 of the first lifting guide wheel, and the mounting hole of the first adjusting bushing 46 is provided with a keyway for installing the first flat key.

The second drive chain 22 is meshed with the second driven sprocket 28 and the second counterweight wheel 38 respectively, and the second counterweight wheel 38 is located below the second driven sprocket 28.

[0085] When the second motor 20 drives the intermediate layer vehicle platform assembly 16 upward, the second counterweight 37 and the second counterweight wheel 38 move downward under their own weight to keep the chain taut. Conversely, when the second motor 20 drives the intermediate layer vehicle platform assembly 16 downward, the second counterweight 37 and the second counterweight wheel 38 are pulled upward.

[0086] As one embodiment of this example, the intermediate layer vehicle platform assembly 16 includes a second vehicle platform 39 and a second boom 40. The second boom 40 is fixed to both ends of the second vehicle platform 39 along its width direction. A second lifting guide wheel 41 is rotatably mounted on the second boom 40 through a second lifting guide wheel mounting assembly.

[0088] The second lifting guide wheel 41 is mounted on the second lifting guide wheel eccentric shaft 49 via the second bearing 48;

[0089] The second adjusting bushing 50 is mounted on the second boom 40. The second adjusting bushing 50 has a mounting hole for mounting the second lifting guide wheel eccentric shaft 49, and the second lifting guide wheel eccentric shaft 49 is mounted on the second adjusting bushing 50 through the second auxiliary part 54. The eccentric position of the second lifting guide wheel eccentric shaft 49 is changed by rotating the angle of the second adjusting bushing 50, which is used to adjust the relative position between the second lifting guide wheel 41 and the second guide groove 18.

[0090] The second lifting guide wheel mounting assemblies are arranged in pairs, located at the upper and lower ends of the second boom 40, respectively.

[0091] The second flat key is on the eccentric shaft 49 of the second lifting guide wheel. The mounting hole of the second adjusting bushing 50 is provided with a keyway for installing the second flat key. The second flat key and the keyway in the second adjusting bushing 50 are locked together by the second auxiliary part 54.

[0092] Furthermore, the annular plate at the end of the second adjusting bushing 50 is provided with multiple connecting holes, and the connecting holes are detachably mounted on the second boom 40 through connecting screws.

[0093] As one embodiment of this example, the second boom 40 is equipped with boom anti-sway guide wheels 43 and second vehicle platform left and right anti-sway guide wheels 52 via support 42.

This device is used to prevent the vehicle platform from falling if the transmission chain breaks after the top layer vehicle platform assembly 15 and the middle layer vehicle platform assembly 16 have been raised to the upper position, thus ensuring the safety of people and vehicles.

[0100] The lifting-type multi-level parking system in this plan can also be equipped with other safety devices, such as over-limit operation prevention devices, human and vehicle accident detection devices, vehicle blocking devices, power-off brakes, control interlocking devices, under-phase protection devices, power overload protection devices, operation time protection devices, manual operation functions, fault LCD displays, maintenance platforms and ladders, and safety nets.

[0101] The working principle of this solution is as follows:

[0102] In the initial state, the top layer vehicle platform assembly 15 and the middle layer vehicle platform assembly 16 are stacked on the ground. When the first car enters the top layer vehicle platform assembly 15 and stops, the electrical control system controls the first motor 19 to work, and the top layer vehicle platform assembly 15 moves upward and stops after stopping at the preset position.

[0103] Then, after the second car enters the intermediate layer vehicle platform assembly 16 and comes to a stop, the electrical control system controls the second motor 20 to work, and the intermediate layer vehicle platform assembly 16 moves upward and stops after parking in the preset position.

[0104] The third car can drive directly to the middle level under the vehicle platform and park there.

[0105] This solution allows for flexible layout, enabling both small-scale deployments to multiply the number of parking spaces and large-scale, dense deployments to increase the number of parking spaces significantly. Some implementation methods are as follows:

[0106] Independent horizontal or vertical arrangement of a single or multiple sets of equipment;

[0107] Single-row equipment is arranged in multiple rows continuously in the width direction;

[0108] Multi-row equipment is arranged in multiple rows or columns continuously or intermittently in both the length and width directions.

[0109] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
