Like platform exchange technology, it represents the core of fully automated stereo garages and represents a different direction in the development of stereo garage technology. Comb-tooth exchange stereo garages are popular for their simple structure, low energy consumption during vehicle exchange through the comb-tooth structure, and short travel times during vehicle storage and retrieval, greatly improving storage and retrieval efficiency.

[0067] The utility model also provides a method for using a comb tooth exchange lifting device for a garage, comprising the following steps:

[0068] The parking process is as follows:

[0069] A1: Before the vehicle enters the device, the lifting comb rack 22 is lowered to the lowest position (refer to Figure 17 ), at this time, the lifting comb rack 22 is flush with the upper surface of the comb support mechanism 3, and then the guide pushing mechanism 32 and the wheel block mechanism 33 are controlled to rise (refer to Figure 18 );

[0070] A2: Then the vehicle drives in, and the pulley assembly 34 cooperates with the guide and pushing mechanism 32 to push the vehicle to the center of the device (see

[0071] According to Figure 19 and Figure 20 );

[0072] A3: Then the guide and pushing mechanism 32 is folded and lowered to the low position, and the wheel blocking mechanism 33 is folded and lowered to the low position;

[0073] A4: The comb tooth lifting device 21 controls the lifting comb tooth frame 22 to rise. During the process, the lifting comb tooth frame 22 and the comb teeth on the comb tooth mechanism 31 are interlaced. The vehicle is exchanged once. That is, at this time, the vehicle is supported by the comb teeth on the lifting comb tooth frame 22 instead of the lifting comb tooth frame 22 and the comb teeth in the comb tooth mechanism 31.

[0074] Rack 22 is raised to the high position (refer to Figure 21 );

[0075] A5: Then control the filling mechanism 4 to rise to the highest position to fill the gap caused by the rise of the lifting comb rack 22. At this time, the filling mechanism 4 is flush with the upper surface of the comb support mechanism 3, providing support for the AGV to walk. The AGV is a special AGV for vehicle transportation. There are comb teeth on the top of the AGV. The comb teeth are staggered with the comb teeth on the lifting comb rack 22. The AGV can

[0076] Able to enter and exit the device horizontally and vertically (refer to Figure 16 );

[0077] A6: The AGV passes through the walking track on the comb mechanism 31 and moves to the front of the lifting comb frame 22 through the filling mechanism 4.

[0078] Below (refer to Figure 22 );

[0079] A7: Then control the filling mechanism 4 to descend to the low position to prevent it from affecting the next descent of the lifting comb rack 22 (refer to

[0080] Figure 23 );

[0081] A8: The comb teeth lifting device 21 moves in the reverse direction to lower the lifting comb teeth frame 22 to the lowest position. At this time, the comb teeth on the lifting comb teeth frame 22 intersect with the comb teeth on the AGV and then fall down. During this process, the vehicle falls on the comb teeth of the AGV, completing the secondary exchange of vehicles. That is, at this time, the vehicle is supported by the comb teeth on the lifting comb teeth frame 22 and is completely supported by the comb teeth on the AGV.

[0082] Support (refer to Figure 24 );

[0083] A9: Finally, the AGV can take the vehicle out of the device and move it to the corresponding parking space for the next parking process (refer to Figure 25 ).

[0084] The process of picking up the car is as follows:

[0085] B1: Before the AGV enters the device, the lifting comb rack 22 is lowered to the lowest position (refer to Figure 17 ), then rise

[0086] The comb tooth frame 22 is flush with the upper surface of the comb tooth support mechanism 3;

[0087] B2: The AGV carries the vehicle through the walking track on the comb mechanism 31 to the top of the exchange mechanism (such as Figure 24 ); B3: Then control the comb tooth lifting device 21 to make the lifting comb tooth frame 22 rise. At this time, the comb teeth in the lifting comb tooth frame 22 are staggered with the comb teeth on the AGV. The lifting comb tooth frame 22 continues to rise until all vehicles are supported by the comb teeth on the lifting comb tooth frame 22. In the process, one vehicle exchange is completed. The vehicle is raised to the high position together with the lifting comb tooth frame 21. That is, at this time, the vehicle is supported by the comb teeth on the lifting comb tooth frame 22 instead of the comb teeth on the AGV (refer to Figure 23 ); B4: Then the filling mechanism 4 is raised to the high position to fill the gap generated by the lifting comb rack 22 rising. At this time, the filling mechanism 4 is flush with the upper surface of the comb support mechanism 3, providing support for the AGV to walk (refer to Figure 22 );

[0088] B5: The AGV passes through the walking track on the comb mechanism 31 and leaves the device through the filling mechanism 4;

[0089] B6: Then the filling mechanism 4 is lowered to the low position to prevent it from affecting the next descent of the lifting comb rack 22;

[0090] B7: The comb teeth lifting device 21 moves in the reverse direction to lower the comb teeth lifting frame 22 to the lowest position. During this process, the vehicle falls on the comb teeth mechanism 31 to complete the second vehicle exchange. That is, at this time, the vehicle is supported by the comb teeth on the comb teeth lifting frame 22 and then changes to the vehicle supported by the teeth on the comb teeth lifting frame 22.

[0091] The comb teeth support 22 and the comb teeth support 31 are lifted and lowered (see Figure 20 );

[0092] B8: Finally, the driver drives the vehicle away from the device.

[0093] It should be noted that the vehicle pickup process is equivalent to the reverse process of the vehicle parking process.
