The slide post 171b is slidably installed in the slide groove 172b. Specifically, the slide post 171b can be a bolt.

[0057] The first tensioning wheel assembly 17 is used to adjust the tightness of the first chain 11d. When the first chain 11d is loosened during operation, the first adjusting bolt 17c is rotated to move the first adjusting bolt 17c along the threaded hole toward the inside of the first driving arm frame 8. The first end of the moving first adjusting bolt 17c drives the first mounting block 17b to slide on the first driving arm frame 8, so that the first mounting block 17b can drive the first tensioning wheel 17a to move, thereby changing the shape of the first chain 11d, thereby adjusting the tightness of the first chain 11d, so that the first chain 11d can effectively drive the first vehicle carrier driving wheel 12 to rotate and avoid slipping.

[0058] Specifically, the vehicle plate dragging device 100 may further include: a vehicle plate position sensor 19, which is installed on the first driving arm frame 8 by screws. When the vehicle plate a approaches the first driving arm frame 8, the metal plate on the vehicle plate a senses the vehicle plate position sensor 19, and the signal is transmitted to the control system through the vehicle plate position sensor 19, thereby realizing the position sensing of the vehicle plate a.

In implementation, the bracket 21 may be installed on the central lifting platform 200 by bolts.

[0060] When the sensing plate 20 follows the first movable frame 6 to move along the first vehicle loading plate guide rail 4, the sensing plate 20 will sequentially sense with the plurality of sensing sensors 22, thereby determining the current position of the first movable frame 6 relative to the first vehicle loading plate guide rail 4. In this embodiment, there may be four sensing sensors 22, namely, the first sensing sensor 22, the second sensing sensor 22, the third sensing sensor 22 and the fourth sensing sensor 22, the four sensing sensors 22 are arranged equidistantly, and the width of the sensing plate 20 may be equal to the distance between two adjacent sensing sensors 22, that is, the sensing plate 20 can cooperate with two adjacent sensing sensors 22 at the same time. When the sensing plate 20 corresponds to the first sensing sensor 22 and the second sensing sensor 22, the vehicle plate dragging device 100 moves from the surrounding parking spaces to the closest to the central lifting platform 200 and reaches the limit. When the sensing plate 20 corresponds to the second sensing sensor 22 and the third sensing sensor 22, the vehicle plate dragging device 100 is at the center position of the reciprocating movement. When the sensing plate 20 corresponds to the third sensing sensor 22 and the fourth sensing sensor 22, it means that the vehicle plate dragging device 100 moves from the central lifting platform 200 to the surrounding parking space frames 400 and reaches the limit. The sensing plate 20 and multiple sensing sensors 22 can provide a sensing reference basis for the control of the entire vehicle plate dragging device 100.

Compared with the screw, the connecting rod 23 does not need to be processed with threads, so the processing of the connecting rod 23 is simple and the cost is lower. The provision of the connecting rod 23 can shorten the length of the first worm 2, which can reduce the processing cost of the vehicle loading plate towing device 100.

[0062] The clamping assembly 14 includes: a pull rod 14a, two springs 14b and two adjusting nuts 14c.

One spring 14b is pressed between one adjusting nut 14c and the first driving arm frame 8, and the other spring 14b is pressed between the other adjusting nut 14c and the second driving arm frame 9.

[0076] The following is a brief introduction to the working principle of the car plate dragging system, as follows:

[0077] The vehicle plate towing system drives the vehicle plate a through the vehicle plate towing device 100, so that the vehicle plate a can reciprocate between the central lifting platform 200 and the parking space frame 400. Specifically, the vehicle plate a is usually parked in the parking space in a non-towing state, and the car is parked on the vehicle plate a. When the vehicle plate a needs to be towed to move the vehicle plate a from the parking space to the central lifting platform 200, the towing drive unit 1 is driven to drive the first worm 2 to move in the direction of the vehicle plate a. When the guide plate a1 of the vehicle plate a moves between the first clamping plate 12a and the second clamping plate 13a, the clamping drive unit 10 is driven, and the clamping drive unit 10 drives the first transmission unit 11 to make the first clamping plate 12a and the second clamping plate 13a rotate in opposite directions relative to each other. Specifically, the first clamping plate 12a rotates counterclockwise, and the second clamping plate 13a rotates clockwise, so that the guide plate a1 It is clamped by the first clamping disc 12a and the second clamping disc 13a, and the guide plate a1 can be driven by the rotating first clamping disc 12a and the second clamping disc 13a to move toward the central lifting platform 200 along the rotation direction of the first clamping disc 12a and the second clamping disc 13a. At the same time, the dragging drive unit 1 is driven to work in reverse, so that the dragging drive unit 1 drives the first worm 2 to move toward the central lifting platform 200. After the vehicle loading plate a is completely moved to the annular table 206 of the central lifting platform 200, the dragging drive unit 1 stops working and starts the winch 600. The winch 600 changes the length of the wire rope 500 between the winch 600 and the central lifting platform 200 by winding the wire rope 500, thereby lifting the central lifting platform 200. During the lifting process, the central lifting platform 200 can move along the platform lifting guide rail 300 to realize the transportation operation of the car.

[0078] When it is necessary to drag the vehicle carrier plate a so that the vehicle carrier plate a moves from the central lifting platform 200 to the parking space, the vehicle carrier plate a is lifted and rotated by the central lifting platform 200 to the corresponding parking space, and the clamping drive unit 10 is driven. The clamping drive unit 10 drives the first transmission unit 11 to make the first clamping disk 12a and the second clamping disk 13a rotate relative to each other, so that the guide plate a1 is clamped by the first clamping disk 12a and the second clamping disk 13a, and then the dragging drive unit 1 is driven to drive the first worm 2 to move toward the parking space. When the vehicle carrier plate a is completely moved to the parking space, the clamping drive unit 10 stops working, and the guide plate a1 is no longer clamped by the first clamping disk 12a and the second clamping disk 13a, and the dragging drive unit 1 is driven to drive the first worm 2 to move toward the central lifting platform.

[0079] The vehicle plate towing system provided by the embodiment of the present disclosure comprises a plurality of parking spaces arranged in a ring formed by parking space frames, a central lifting platform arranged in the center of the ring formed by the plurality of parking spaces, and a vehicle plate towing device installed in the middle of the central lifting platform. The system drives the vehicle plate to move through the vehicle plate towing device, so that the vehicle plate can reciprocate between the central lifting platform and the parking space frame, and changes the height of the connection end of the steel wire rope and the central lifting platform by winding a steel wire rope by a winch, thereby driving the central lifting platform to be lifted and lowered with the cooperation of a counterweight block. Specifically, the vehicle plate towing device realizes the movement of the first worm gear and the first towing unit through a towing drive unit, and the clamping drive unit can enable the first clamping plate and the second clamping plate to generate a rolling clamping force on the guide plate at the bottom of the vehicle plate, thereby dragging the vehicle plate back and forth between the central lifting platform and the parking space frame. The vehicle plate dragging system only needs to be equipped with one vehicle plate dragging device to complete the parking work of multiple parking spaces and multi-story parking spaces, which greatly reduces the processing cost of the vehicle plate dragging system, is more conducive to the promotion and application of the vehicle plate dragging system, and is also convenient for the maintenance and maintenance of the parking garage in the later stage. Moreover, the vehicle plate dragging system operates smoothly under the joint action of the dragging drive unit and the clamping drive unit, and has a reliable structure.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
