[0028] 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.

[0029] like Figures 1 to 5 As shown, the embodiment of the present application provides a driving system for a vertical lifting garage, including: a top frame body 1; two lifting drive devices 2, the two lifting drive devices 2 are respectively installed on opposite sides of the top frame body 1, the lifting drive device 2 includes a lifting main motor 21, a lifting sub-motor 22, and a transmission shaft assembly 23, the driving shaft of the lifting sub-motor 22 is connected to the driving shaft of the lifting main motor 21, the driving shaft of the lifting main motor 21 is connected to the transmission shaft assembly 23, the lifting main motor 21 drives the transmission shaft assembly 23 to rotate, and a first lifting sprocket 24 and a first synchronous sprocket 25 are installed on the transmission shaft assembly 23, and the two first lifting sprockets 24 are respectively connected to the two sides of the lifting frame through lifting chains; a synchronization device 3, installed on the top frame body 1, the synchronization device 3 is located between the two lifting drive devices 2, and the first synchronous sprockets 25 of the two lifting drive devices 2 are connected through the synchronization device 3 to adjust the synchronous rotation of the two first synchronous sprockets 25.

[0030] When the drive system is applied to a vertical lift garage, the first lift sprocket 24 is connected to the lift frame through a lift chain. When the vertical lift garage is under normal load, the lift main motor 21 is directly started, and the lift main motor 21 drives the first lift sprocket 24 to rotate and then drives the lift frame to lift; when it is not loaded, that is, in the early installation and later maintenance stages, the lift sub-motor 22 is started, and the drive shaft of the lift sub-motor 22 drives the drive shaft of the lift main motor 21 to rotate, thereby driving the first lift sprocket 24 to rotate and drive the lift frame to lift. The lift sub-motor 22 can select a motor with relatively small power to reduce its operating cost. The drive system of the embodiment of the present application can use motors of different powers to drive the lifting of the lift frame under load and non-load conditions, which can not only ensure the stable operation of the vertical lift garage under load, but also reduce the operating cost in the early test and later maintenance stages. Preferably, the connection method of the first lift sprocket 24 to the lift frame through the lift chain is an existing connection method, which is a prior art.

[0031] Since the two first lifting sprockets 24 are connected to the two sides of the lifting frame through the lifting chains, and the first synchronous sprockets 25 of the two lifting drive devices 2 are connected through the synchronization device 3, the two first synchronous sprockets 25 are rotated synchronously through the synchronization device 3, and then the first lifting sprockets 24 of the two lifting drive devices 2 are rotated synchronously, so that the two sides of the lifting frame of the vertical lifting garage can be lifted synchronously, avoiding malfunctions caused by the failure of the two sides of the lifting frame to be lifted synchronously.

[0032] In order to realize the lifting of the lifting frame, the transmission shaft assembly 23 includes at least a first lifting shaft 231, which is connected to the lifting main motor 21. The lifting main motor 21 drives the first lifting shaft 231 to rotate, and the first lifting sprocket 24 and the first synchronous sprocket 25 are both installed on the first lifting shaft 231.

[0033] In one embodiment, the connection method between the driving shaft of the lifting main motor 21 and the first lifting shaft 231 can be any existing connection method, as long as the connection between the driving shaft of the lifting main motor 21 and the first lifting shaft 231 can be achieved and the first lifting shaft 231 can be driven to rotate.

[0034] The transmission shaft assembly 23 also includes a second lifting shaft 232 and a universal coupling 233. The first lifting shaft 231 is connected to the second lifting shaft 232 through the universal coupling 233. The second lifting shaft 232 is also equipped with a first lifting sprocket 24 and a first synchronous sprocket 25. The first lifting sprocket 24 is also connected to the lifting frame through a lifting chain, and the first lifting sprocket 24 on the first lifting shaft 231 and the first lifting sprocket 24 on the second lifting shaft 232 are respectively connected to the two ends of the lifting frame through lifting chains.

[0035] Since the first lifting shaft 231 is connected to the second lifting shaft 232 through the universal connecting shaft 233, during the rotation of the first lifting shaft 231 and the second lifting shaft 232, the first lifting shaft 231 and the second lifting shaft 232 are aligned through the universal coupling 233 to ensure that the first lifting shaft 231 and the second lifting shaft 232 rotate together and transmit torque, thereby ensuring that the first lifting shaft 231 and the second lifting shaft 232 can run smoothly, reduce wear, reduce failure rate, and reduce later maintenance costs.

[0036] The two ends of the universal coupling 233 are fixed with coupling flanges 234 by bolts, the coupling flange 234 at one end of the universal coupling 233 is connected to the connection hole at the end of the first lifting shaft 231 by bolts, and the coupling flange 234 at the other end of the universal coupling 233 is connected to the connection hole at the end of the second lifting shaft 232 by bolts. Bearings 27 are installed on the first lifting shaft 231 and the second lifting shaft 232, and the bearing box of the bearing 27 is fixed on the top frame body 1.

[0037] The lifting motor 22 is a reduction motor. The lifting drive device 2 further includes a chain coupling 26 . The driving shaft of the lifting motor 22 is connected to the driving shaft of the lifting main motor 21 via the chain coupling 26 .

[0038] Since two first synchronous sprocket wheels 25 are arranged on one lifting drive device 2, the number of the synchronous devices 3 is also set to two, and the two first synchronous sprocket wheels 25 located at the same end of the lifting frame are respectively connected to the same synchronous device 3.

[0039] In order to realize the synchronous rotation of the two first synchronous sprockets 25, the synchronous device 3 includes a synchronous seat 31, a first synchronous assembly 32 and a second synchronous assembly 33. The synchronous seat 31 is fixed on the top frame body 1, and the first synchronous assembly 32 and the second synchronous assembly 33 are respectively rotatably connected to the synchronous seat 31. The first synchronous assembly 32 is connected to the first synchronous sprocket 25 of one of the lifting drive devices 2, and the second synchronous assembly 33 is connected to the first synchronous sprocket 25 of the other lifting drive device 2, and the first synchronous assembly 32 is meshed with the second synchronous assembly 33.

[0040] The first synchronous assembly 32 and the second synchronous assembly 33 both include a synchronous shaft 321, a second synchronous sprocket 322 and a synchronous gear 323. The synchronous shaft 321 is connected to the synchronous seat 31, the second synchronous sprocket 322 and the synchronous gear 323 are respectively sleeved on the synchronous shaft 321, and the second synchronous sprocket 322 is connected to the synchronous gear 323. Preferably, the synchronous shaft 321 can be connected to the synchronous seat 31 through a clamping plate 324 and a screw, the second synchronous sprocket 322 and the synchronous gear 323 can be connected through a hexagon socket head screw, and the second synchronous sprocket 322 and the synchronous gear 323 can rotate relative to the synchronous shaft 321. Two positioning rings 326 are fixed on the synchronous shaft 321, and the second synchronous sprocket 322 and the synchronous gear 323 are located between the two positioning rings 326. The second synchronous sprocket 322 of the first synchronous assembly 32 is connected to the first lifting sprocket 24 of one lifting drive device 2 through a synchronous chain 325, the second synchronous sprocket 322 of the second synchronous assembly 33 is connected to the first lifting sprocket 24 of the other lifting drive device 2 through a synchronous chain 325, and the synchronous gear 323 of the first synchronous assembly 32 is meshed with the synchronous gear 323 of the second synchronous assembly 33. Preferably, the first lifting sprocket 24 and the second synchronous sprocket 322 are both double-row sprockets, and the synchronous chain 325 is a double-row chain.

[0041] The embodiment of the present application uses the setting of the synchronization device 3 to enable the first lifting sprocket wheels 24 of the two lifting drive devices 2 to rotate synchronously, thereby ensuring that both sides of the lifting frame can be lifted and lowered synchronously, avoiding the situation where the two sides of the lifting frame are lifted and lowered asynchronously, reducing the failure rate, and making the lifting frame operate more safely and reliably when storing and retrieving cars.

[0042] In order to be able to adjust the tension of the synchronous chain 325, the driving system for the vertical lifting garage also includes four tensioning devices 4. The four tensioning devices 4 are all installed on the top frame 1, and the four tensioning devices 4 are respectively connected to the four synchronous chains 325.

[0043] Furthermore, the tensioning device 4 includes a tensioning seat 41, a first tensioning wheel 42, a second tensioning wheel 43 and a third tensioning wheel 44. The tensioning seat 41 is mounted on the top frame 1, and the first tensioning wheel 42, the second tensioning wheel 43 and the third tensioning wheel 44 are all rotatably connected to the tensioning seat 41, and the second tensioning seat 41 is located between the first tensioning wheel 42 and the third tensioning wheel 44. The synchronous chain 325 is connected to the first tensioning wheel 42, the second tensioning wheel 43 and the third tensioning wheel 44, and the second tensioning wheel 43 can move up and down on the tensioning seat 41.

[0044] In one embodiment, a tensioning seat 41 may be provided with a vertically arranged tensioning adjustment slot 45, and the tensioning device 4 further includes an adjustment plate 46, on which a rotating shaft 47 is arranged, and the second tensioning wheel 43 is connected to the rotating shaft 47. The rotating shaft 47 is located in the tensioning adjustment slot 45, and the adjustment plate 46 is detachably connected to the tensioning seat 41 by bolts. By adjusting the position of the adjustment plate 46, the rotating shaft 47 is moved in the tensioning adjustment slot 45, and the position of the second tensioning wheel 43 is adjusted. The tensioning state of the synchronous chain 325 can be adjusted by adjusting the position of the second tensioning wheel 43.
