[0040] Working principle of the present invention:

[0041] The present invention is a comb-tooth exchange type vertical lifting device, wherein:

[0042] In normal state, the left and right halves of the split comb-tooth type filling plate 1 are moved along the horizontal rail to the middle parking space to fill the foundation pit below, and the comb-tooth type lifting plate 3 falls on the split comb-tooth type filling plate 1, and the car drives in directly;

[0043] When there is a parking space on the ground, the comb-tooth lifting plate 3 is directly lifted along the vertical guide rail to exchange with the parking space above, and the comb-tooth lifting plate 3 parks the car on the upper parking space located on both sides of the comb-tooth filling plate 1;

[0044] When the car is to be parked, the comb-tooth lifting plate 3 is slightly lifted by the lifting column 2, and the motor reducer 13 of the left and right halves of the comb-tooth type filling plate 1 is driven to move the comb-tooth type filling plate 1 to the bottom of the left and right parking spaces respectively, making way for the lifting channel, and the comb-tooth type lifting plate 3 is lowered to the underground garage and exchanged with the underground berth. After completion, the comb-tooth lifting plate 3 rises to the ground, and the motor reducer 13 of the left and right halves of the comb-tooth type filling plate 1 is driven to move the comb-tooth type filling plate 1 to the middle respectively, forming an integral pit filling plate.

[0045] The specific transmission mode of the split comb-tooth type filling plate 1 is:

[0046] Due to the phenomenon of broken rails on the horizontal rails, two driven wheels 6 are provided at the front and rear of each half-divided comb-tooth type filling plate 1 to facilitate cross-rail operation and smooth operation; a motor sprocket 12 is provided on the motor reducer 13, a follower sprocket 10 is provided on the synchronous shaft 8, and a driving wheel 9 is provided at the front and rear;

[0047] During operation, the motor reducer 13 is energized, and the motor reducer 13 drives the motor sprocket 12 to rotate through the motor shaft. The transmission chain 11 meshing with the motor sprocket 12 is meshed with the gear teeth, and the transmission is driven by the follower sprocket 10 meshing with the motor sprocket 12. The follower sprocket 10 is installed on the synchronous shaft 8. With the rotation of the follower sprocket 10, the synchronous shaft 8 also rotates synchronously to drive the driving wheel 9 installed on the synchronous shaft 8 to rotate. The driving wheel 9 rotates and moves along the horizontal rail, driving the rotation and movement of the driven wheel 6, thereby realizing the left and right movement of the comb-tooth type filling plate 1;

[0048] The two motor reducers 13 have different directions of rotation, so the two halves of the comb-toothed patching plate 1 can move away from each other and join together by moving left and right, thereby realizing the switching between the leveling mode (the two halves of the comb-toothed patching plate 1 are joined together to form an integral pit-filling plate for easy vehicle removal) and the lifting mode (the two halves of the comb-toothed patching plate 1 are moved to the bottom of the left and right parking spaces to clear the lifting channel for easy lifting of the comb-toothed lifting plate 3).

[0049] The present invention facilitates the left and right movement of the split comb-tooth type filling plate 1 through a moving component, and facilitates the power for the movement of the split comb-tooth type filling plate 1 through a motor reducer 13. The driven sprocket 10, the transmission chain 11 and the motor sprocket 12 are meshed and transmitted, so that the driving wheel 9 drives the driven wheel 6 to rotate to drive the movement of the split comb-tooth type filling plate 1. By arranging the split comb-tooth type filling plate 1 below the comb-tooth type lifting plate 3, it is convenient to form an integral pit-filling plate to realize the middle-layer vehicle discharge or the top-layer vehicle discharge. Through the leveling mechanism, it is convenient to move the split comb-tooth type filling plate 1 to the left and right, and can realize the switching between the leveling mode and the lifting mode. It can also level the hole in the middle of the left and right half comb-tooth frames that are being lifted, so that the lifting equipment is convenient to be applied to the middle-layer vehicle discharge or the top-layer vehicle discharge, so that it has a wider range of adaptability, so as to improve the market share of the comb-tooth type vertical lifting equipment. Through the supporting mechanism, it is convenient to fix, install and connect the split comb-tooth type filling plate 1 and various components thereon to ensure the overall stable operation of the device.
