[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] Embodiment 1:

[0029] like Figures 1 to 3 As shown, an embodiment of the present application provides a vertical lifting device, including: a driving assembly, including a lifting main motor 1 and a lifting sub-motor 2, the driving shaft of the lifting sub-motor 2 is connected to the driving shaft of the lifting main motor 1; a universal coupling 3; a first lifting shaft 4, one end of which is connected to the driving shaft of the lifting main motor 1, and is driven to rotate by the driving shaft of the lifting main motor 1, and a first lifting sprocket 5 is provided on the first lifting shaft 4; a second lifting shaft 6, one end of which is connected to the first lifting shaft 4 through a universal coupling 3, and a second lifting sprocket 7 is provided on the second lifting shaft 6.

[0030] When the driving shaft of the lifting main motor 1 drives the first lifting shaft 4 to rotate, the first lifting shaft 4 drives the second lifting shaft 6 to rotate through the universal coupling 3. During the rotation of the first lifting shaft 4 and the second lifting shaft 6 of the embodiment of the present application, the first lifting shaft 4 and the second lifting shaft 6 are aligned through the universal coupling 3 to ensure that the first lifting shaft 4 and the second lifting shaft 6 rotate together and transmit torque, thereby ensuring that the first lifting shaft 4 and the second lifting shaft 6 can run smoothly, reduce wear, reduce failure rate, and reduce later maintenance costs.

[0031] In one embodiment, the universal joint 3 can be a cross-axis universal joint, a ball cage universal joint, a ball fork universal joint, etc.

[0032] The first lifting shaft 4 is provided with a first lifting sprocket 5, and the second lifting shaft 6 is provided with a second lifting sprocket 7. The first lifting sprocket 5 and the second lifting sprocket 7 can be connected to other components that need to be lifted by chains. When the vertical lifting device is applied to a stereo garage, the first lifting sprocket 5 and the second lifting sprocket 7 can be connected to the vehicle loading plate by chains.

[0033] In order to realize the connection between the lifting main motor 1 and the lifting sub-motor 2, the driving assembly further includes a chain coupling 8, and the driving shaft of the lifting sub-motor 2 is connected to the driving shaft of the lifting main motor 1 through the chain coupling 8. Among them, the connection method between the driving shaft of the lifting main motor 1 and the first lifting shaft 4 can be any existing connection method, as long as the connection between the driving shaft of the lifting main motor 1 and the first lifting shaft 4 can be realized and the first lifting shaft 4 can be driven to rotate.

[0034] Since the lifting main motor 1 and the lifting sub-motor 2 are provided, and the driving shaft of the lifting sub-motor 2 is connected to the driving shaft of the lifting main motor 1 through the chain coupling 8, under normal load conditions, the lifting main motor 1 is directly started, and the lifting main motor 1 drives the first lifting shaft 4 to rotate, thereby driving the lifting of the vehicle-carrying plate, etc. connected to the first lifting sprocket 5 and the second lifting sprocket 7 through the chain. Under non-load conditions, that is, during early installation and later maintenance, it is only necessary to start the lifting sub-motor 2, and the driving shaft of the lifting sub-motor 2 drives the driving shaft of the lifting main motor 1 to rotate through the chain coupling 8, thereby driving the first lifting shaft 4 to rotate, and further driving the lifting of the vehicle-carrying plate, etc. connected to the first lifting sprocket 5 and the second lifting sprocket 7 through the chain. Preferably, the lifting sub-motor 2 is a reduction motor, and the power of the lifting sub-motor 2 is less than the power of the lifting main motor 1. By setting the lifting main motor 1 and the lifting sub-motor 2, the embodiment of the present application only needs to start the lifting sub-motor 2 in the early installation and later maintenance stages, thereby reducing costs, solving the problem of time-consuming and labor-consuming installation and debugging under non-load conditions, and reducing noise.

[0035] The other end of the first lifting shaft 4 is provided with a first synchronous sprocket 9, and the other end of the second lifting shaft 6 is provided with a second synchronous sprocket 10. In order to realize the connection between the universal coupling 3 and the second lifting shaft 6 and the first lifting shaft 4, the vertical lifting device also includes two connecting components, one end of the universal coupling 3 is connected to the second lifting shaft 6 through one of the connecting components, and the other end of the universal coupling 3 is connected to the first lifting shaft 4 through the other connecting component.

[0036] Furthermore, the connection assembly is a coupling flange 11, which can be fixed to the end of the universal coupling 3 by bolts, etc. One coupling flange 11 is bolted to the connection hole at the end of the second lifting shaft 6, and the other coupling flange 11 is bolted to the connection hole at the end of the first lifting shaft 4.

[0037] The vertical lifting device also includes a top frame 13, and the driving assembly is installed on the top frame 13. The lifting main motor 1 and the lifting sub-motor 2 of the driving assembly can be fixed to the top frame 13 by bolts or the like. The first lifting shaft 4 and the second lifting shaft 6 are both installed with bearings 12, and the bearing box of the bearing 12 is installed on the top frame 13.

[0038] The first lifting shaft 4 and the second lifting shaft 6 of the vertical lifting device of the embodiment of the present application are connected by a universal coupling 3. The universal coupling 3 can be adjusted to make the first lifting shaft 4 and the second lifting shaft 6 concentric, thereby reducing the wear of the universal coupling 3, the first lifting shaft 4 and the second lifting shaft 6, extending their service life and reducing the failure rate.

[0042] After the driving assembly is started, the lifting main motor 1 of the driving assembly drives the first lifting shaft 4 to rotate, the first lifting shaft 4 drives the second lifting shaft 6 to rotate through the universal coupling 3, the first lifting shaft 4 drives the first lifting sprocket 5 to rotate, and the second lifting shaft 6 drives the second lifting sprocket 7 to rotate. The first lifting sprocket 5 and the second lifting sprocket 7 drive the chain to move, thereby driving the lifting of the vehicle loading plate.

[0043] In one embodiment, a driven sprocket may be further provided on the vehicle carrying plate, the chain is an annular chain, the vehicle carrying plate is connected to the chain, and the driven sprocket meshes with the chain to transmit power.

[0045] By connecting the first synchronous sprockets 9 of the two vertical lifting devices through a synchronous chain, and connecting the second synchronous sprockets 10 of the two vertical lifting devices through a synchronous chain, it can be ensured that the first lifting shaft 4 and the second lifting shaft 6 of the two vertical lifting devices rotate synchronously, ensuring that the two side edges of the vehicle loading plate can be lifted and lowered synchronously.
