Description

Technical Field

[0001] The utility model relates to the technical field of vehicle handling, in particular to a vehicle transfer device for a parking lot. Background Art

[0002] A vehicle transfer device for a parking lot is a system specially designed to efficiently and safely move vehicles within a parking lot. This device is mainly used to solve the problem of difficult urban parking, especially in areas with tight land resources. With the annual increase in the popularity rate of cars, the demand for automobile-related facilities is also growing continuously, among which the parking problem is particularly prominent. In traditional parking lots, there are problems with irregular vehicle parking. Usually, one vehicle occupies multiple parking spaces, which not only reduces the effective utilization rate of parking spaces but also brings inconvenience to the management of the parking lot. To address this situation, forklifts are usually used to transfer irregularly parked vehicles.

[0003] The patent with the patent publication number CN220203540U discloses a lifting and supporting device for a three-dimensional parking lot, which includes a lifting seat and a column. Among them, the column is vertically fixed on the ground, a cross beam is provided at the top of the column, a winch is installed on the cross beam, the lifting seat is movably installed on the column, and the lifting rope of the winch is connected to the lifting seat; a sliding seat is installed at the top of the lifting seat, a supporting seat is installed at the top of the sliding seat, there are two groups of supporting seats, which are respectively located on both sides of the top of the sliding seat, a vehicle storage area is reserved between the two supporting seats, a jacking cylinder is provided at the bottom of the supporting seat, the bottom of the jacking cylinder is downward and connected to the sliding seat, and a vehicle lifting roller is installed on the side wall of the supporting seat on one side of the vehicle storage area, and a storage roller channel is reserved between adjacent vehicle lifting rollers.

[0004] For the above-mentioned disclosed lifting and supporting device for a three-dimensional parking lot, the lifting seat is lifted by a winch, and then multiple driving cylinders are used to achieve precise translation of the vehicle, and finally the vehicle is parked at a designated position. However, using multiple driving cylinders to achieve precise translation of the vehicle can increase the manufacturing cost of the device while improving the parking accuracy. And the vehicle wheels are supported by lifting rollers. If the distribution or design of these rollers is unreasonable, it may cause uneven force on the vehicle during the lifting process, thereby affecting the balance and stability of the vehicle. Therefore, it is necessary to design a vehicle transfer device for a parking lot in view of the shortcomings of the prior art. Summary of the Invention

[0005] When the existing lifting and supporting device for a three-dimensional parking lot transfers a vehicle, the vehicle is only lifted by a cylinder, and the vehicle is prone to uneven force during the lifting process, thus increasing the safety risk. To overcome the existing problems, the utility model provides a vehicle transfer device for a parking lot.

It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0021] Embodiment: A vehicle transfer device for a parking lot, as Figures 1-3 shown, includes a frame 1, fixed blocks 2, mounting blocks 3, a first lead screw 4, a second lead screw 5, a connecting plate 6, limit blocks 7, guide plates 9, a moving frame 10, a hydraulic cylinder 11 and a driving assembly. The frame 1 is a load-bearing carrier for moving vehicles in this device. Two fixed blocks 2 are symmetrically mounted on the front side of the frame 1. The fixed blocks 2 are arc wedges. The mounting block 3 is fixedly connected to the rear side of the frame 1. The first lead screw 4 is rotatably connected to the rear side of the frame 1 through the mounting block 3. The left and right parts of the first lead screw 4 are symmetrically provided with internally threaded hollow rods. The second lead screw 5 is symmetrically connected to the left and right parts of the first lead screw 4 through threads. The ends of the second lead screw 5 are fixedly connected with the connecting plate 6. Chutes are opened on the connecting plate 6. The limit blocks 7 are slidably connected to the connecting plate 6 through the chutes. Slots are provided on the left and right sides of the frame 1. The limit blocks 7 symmetrically penetrate and are slidably connected in the slots of the frame 1. The limit blocks 7 cooperate with the fixed blocks 2 to limit and support the tires of the lifted vehicle. Guide plates 9 are symmetrically and fixedly connected to the left and right side walls of the frame 1. The frame 1 is symmetrically slidably mounted with the moving frame 10 through the guide plates 9. Two rollers are mounted at the bottom of the moving frame 10. The rollers of the moving frame 10 are higher than the bottom surface of the frame 1. Hydraulic cylinders 11 are fixedly connected to the left and right sides of the frame 1. The telescopic rods of the hydraulic cylinders 11 are connected to the moving frame 10 on the same side. A driving assembly is provided on the frame 1. The driving assembly is used to drive the first lead screw 4 to rotate. The rotating first lead screw 4 drives the second lead screw 5 to move through threads, so that the second lead screw 5 drives the connecting plate 6 and the limit blocks 7 to move synchronously, so that the limit blocks 7 extend out of the frame 1 and support the tires of the vehicle. After the tires of the vehicle are limited and supported by the cooperation of the fixed blocks 2 and the limit blocks 7, the two hydraulic cylinders 11 drive the moving frame 10 to act downward on the ground, so that the vehicle on the frame 1 can be supported and lifted upward by the moving frame 10.

[0022] As Figure 1 and Figure 4As shown, the limit block 7 is composed of a connecting rod and an arc wedge block. The connecting rod of the limit block 7 passes through the sliding groove of the connecting plate 6, and the arc wedge block of the limit block 7 and the supporting surface of the fixed block 2 are of the same center of circle. Buffering pads with patterns are provided on the supporting surfaces of the fixed block 2 and the limit block 7, and the buffering pads can stably limit the tires of the vehicle.

[0023] As Figure 1 and Figure 2 shown, the driving assembly includes a fixing plate 12, a driving wheel 121, a driving motor 13, a driving belt 14 and a belt pulley 15. The fixing plate 12 is fixedly connected to the top of the frame 1. The driving wheel 121 is rotatably installed on the fixing plate 12. The driving motor 13 is installed on the frame 1, and the output shaft of the driving motor 13 is connected to the driving wheel 121. A belt pulley 15 is fixedly connected to the middle of the first lead screw 4. A driving belt 14 is wound between the driving wheel 121 and the belt pulley 15. By driving the driving wheel 121 to rotate through the driving motor 13, the driving wheel 121 drives the belt pulley 14 to rotate through the driving belt 14, so that the belt pulley 15 drives the first lead screw 4 to rotate synchronously.

[0024] As Figure 1 shown, a supporting plate 101 is fixedly connected to the frame 1. The supporting plate 101 is located between the two fixed blocks 2. The supporting plate 101 is used to support the chassis of the vehicle, and cooperate with the fixed blocks 2 and the limit blocks 7 to support the tires, so as to improve the stable lifting and moving of the vehicle.

[0025] As Figure 3 shown, it further includes a third lead screw 8 and a knob 81. The third lead screw 8 is rotatably connected in the sliding groove of the connecting plate 6. The third lead screw 8 is threadedly connected to the limit block 7. The end of the third lead screw 8 passes through the connecting plate 6 and is installed with a knob 81. By turning the knob 81 to screw the third lead screw 8, the clamping distance between the limit block 7 and the fixed block 2 is adjusted threadedly, so that the fixed block 2 and the limit block 7 can adapt to vehicle tires of various sizes.

[0026] When using this device to transfer a vehicle in a parking lot, first place the two sets of devices at the positions of the front and rear wheels of the vehicle to be transferred respectively. Then, push the frame 1 so that the fixing blocks 2 of the two devices are respectively close to and in contact with the front and rear wheels of the vehicle. At this time, the support plate 101 will extend under the chassis of the vehicle, and the bottom of the fixing block 2 will support on the lower tread surface of the vehicle tire. The user turns the third lead screw 8 by turning the knob 81, and the rotating third lead screw 8 acts on the limit block 7 through the thread, so that the limit block 7 slides under the guidance of the chute of the connecting plate 6 until the distance between the limit block 7 and the fixing block 2 is adjusted to match the lifting distance of the tire. Then, start the driving motor 13. The driving motor 13 drives the driving wheel 121 to rotate through the output shaft. The rotating driving wheel 121 drives the belt pulley 14 to rotate through the belt. At this time, the belt pulley 15 will synchronously drive the first lead screw 4 to rotate. The rotating first lead screw 4 will drive the two side second lead screws 5 to move through the threads on the left and right, so that the second lead screws 5 will drive the connecting plate 6 and the limit block 7 to move towards the direction close to the frame 1 at the same time until the limit block 7 extends out of the frame 1. The limit block 7 can cooperate with the fixing block 2 to limit and support the vehicle tire. When the limit block 7 and the fixing block 2 respectively and stably limit the vehicle tire, start the hydraulic cylinder 11. The hydraulic cylinder 11 will push the moving frame 10 downward through the telescopic rod. The rollers on the moving frame 10 will extend out from the bottom of the frame 1 and support on the ground. The moving frame 10 supported on the ground will act on the frame 1 through the hydraulic cylinder 11 in the reverse direction, so that the two frames 1 can synchronously lift the front and rear wheels of the vehicle through the fixing block 2 and the connecting plate 6, and the support plate 101 can also support upward on the chassis of the vehicle, thereby improving the stability of the vehicle after being lifted, and it is convenient for the user to transfer the vehicle in the parking lot through the moving frame 10.
