Referring to fig. 2 and 3, a driving wheel set 12 is provided on the frame 11 to drive the frame 11 to run forward, backward, leftward, and rightward. In providing the driving wheel set 12, four differential driving wheel sets as shown in fig. 2 may be employed as the driving wheel set 12 of the entire parking transfer robot. When each differential driving wheel set is provided, referring to fig. 4, each differential driving wheel set may be composed of two motors, two speed reducers, two driving wheels 40, 1 pivoting support bearing 42, and the like, so that the two driving wheels 40 are driven by the two sets of motors and the speed reducers to respectively drive, thereby forming a differential driving mode. Referring to fig. 4, the axle connected between the two driving wheels 40 may be hinged with a hinge shaft 43 perpendicular to the axle, so that the driving wheels 40 can swing to ensure that both driving wheels 40 can be landed even on uneven roads.

That is, as shown in fig. 7, the heights of the two roller rows on the parking transfer robot and the floor level of the vehicle 70 to be transferred are substantially flush, so that the vehicle 70 to be transferred can directly run onto the two roller rows of the frame 11, and each row of the wheels of the vehicle 70 to be transferred is correspondingly parked on one roller row, thereby supporting the vehicle 70 to be transferred. Then, as the driving wheel set 12 drives the vehicle frame 11 to travel, the vehicle 70 to be transported is transported. When the parking transport robot travels to the target position, the vehicle to be transported 70 can be detached from the parking transport robot with the rotation of the rollers 21 in the roller row.

As shown in fig. 1 and 2, the chain wheels 22 of any two adjacent rollers 21 in the same roller row are connected by chain transmission, so that when the chain wheel 22 of one roller 21 in the same roller row rotates, the chain wheels 22 on the adjacent rollers 21 can be rotated by the chain transmission, and the transmission is performed sequentially, so that all the chain wheels 22 in the roller row can be rotated, and the rollers 21 in the whole roller row can be driven to rotate. Specifically, when the chain wheels 22 between any two adjacent rollers 21 in the same roller row are connected, the chain wheels 22 on each roller 21 are double-row chain wheels 22, wherein one row of chain wheels 22 is connected with the chain wheel 22 on one adjacent roller 21 through chain transmission, and the other row of chain wheels 22 is connected with the chain wheel 22 on the other adjacent roller 21 through chain transmission, so that the chain wheels 22 on any adjacent rollers 21 are in chain transmission connection. Of course, other ways than those shown above may be used. For example, a longer chain may be used to chain-drive the sprockets 22 on all of the rollers 21 in the same row.

The parking transfer robot can be aligned only with one end provided with the driven gear 61 and cannot be aligned with the other end, thereby ensuring that the driving gear 31 on the parking transfer robot can be aligned and engaged with the corresponding driven gear 61 of the drum parking space. Of course, there may be two driven gears 61 on the support 51, the two driven gears 61 are respectively located at two ends of the roller row, when the roller parking spaces are assembled by the two roller jiffy stands 50, it is only necessary to ensure that the two driven gears 61 are arranged side by side at each end of the roller parking spaces, and the driven gears 61 at the front and rear ends of the roller jiffy stand 50 can be aligned and engaged with the corresponding driving gear 31 on the parking handling robot, so as to increase the flexibility of the roller jiffy stand 50 when in use.

In the case of embodying the driving connection between the driven gear 61 and the sprocket 22 on the end position drum 21, various modes are also possible, and the specific arrangement mode may be the driving connection between the driving gear 31 and the sprocket 22 on the end position drum 21 shown in the aforementioned parking and carrying robot section. For example, a driving sprocket 62 may be coaxially and fixedly connected to the driven gear 61, and the coaxial fixed connection between the driving sprocket 62 and the driven gear 61 is referred to the connection between the driving gear 31 and the driven sprocket 32, which will not be described herein again. The driving sprocket 62 is connected with the sprocket 22 on the roller 21 at the same end in the roller row through a chain transmission, and reference may be made to the connection manner between the sprocket 22 on the roller 21 at the same end in the roller row and the driven sprocket 32, which is not described herein again. Based on the same principle, the diameter of the driving sprocket 62 is smaller than that of the driven gear 61, and the driving sprocket 62 and the driven gear 61 are both located below the roller row, so that the driven gear 61 and the sprocket 22 on the roller 21 at the end position can be conveniently driven, the mechanical structure is simplified, and the driving sprocket 62 is prevented from influencing the alignment engagement between the driving gear 31 and the driven gear 61.

A carrying flow for carrying a vehicle 70 to be carried in detail will be described with reference to fig. 7 to 10. First, referring to fig. 7, the vehicle 70 to be conveyed travels between the parking transfer robot 10, all the rollers 21 in the roller rows of the parking transfer robot 10 are not rotated, and the two roller sets of the vehicle 70 to be conveyed can directly travel into the two roller rows. Next, referring to fig. 8, the parking transport robot 10 transports the vehicle to be transported 70 to the front of the corresponding drum parking space. Thereafter, referring to fig. 9 and 10, the parking transport robot 10 adjusts the position of the two driving gears 31 in the pair of driving gears 31 on the parking transport robot 10 to be aligned with and engaged with the two driven gears 61 at the same end of the drum parking space, so that the parking transport robot 10 can transmit the power of the drum 21 of the parking transport robot 10 to the drum 21 of the drum parking space at the same time by the driving gears 31. Therefore, the drum 21 of the drum parking space and the drum 21 of the parking transport robot 10 can be rotated simultaneously, so that the vehicle 70 to be transported can be transferred from the parking transport robot 10 to the drum parking space, and then the parking garage process for the vehicle 70 to be transported is completed. If the vehicle 70 to be transported needs to be taken, the transportation process is reversed, and the description is omitted.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
