Description

Technical Field

[0001] This utility model belongs to the field of automated parking system technology, and in particular relates to a vehicle platform storage and retrieval device. Background Technology

[0002] As the number of cars used gradually increases, the demand for parking spaces also gradually increases. However, parking spaces in cities are scarce, so multi-level parking garages are being used more and more widely. Multi-level parking garages expand storage space upwards and downwards, allowing more vehicles to be parked on the same floor area compared to surface parking.

[0003] Existing automated parking systems with pallet trucks are equipped with pallet storage and retrieval devices within the moving aisles, allowing pallets to be stored or retrieved from corresponding parking spaces. Common pallet storage and retrieval devices typically consist of a rotary table with linear guide rails, on which linearly sliding hooks are mounted. Corresponding grooves are provided on the pallet, and the linear movement of the hooks enables the storage and retrieval of the pallet. This structure results in a bulky pallet storage and retrieval system with low space utilization and high cost.

[0004] Therefore, in the field of automated parking system technology, there is still a need for research and improvement of vehicle loading and unloading devices. This is a current research hotspot and focus in the field of automated parking system technology, and it is also the starting point for the completion of this utility model. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to provide a vehicle platform storage and retrieval device to solve the technical problems of large structure, low space utilization and high cost of vehicle platform storage and retrieval device.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a vehicle platform storage and retrieval device, including a mounting base disposed on a lift, on which a first worm and a second worm are rotatably mounted in parallel, the first worm being connected to a first power mechanism and the second worm being connected to a second power mechanism, and a worm wheel being rotatably mounted on the mounting base, meshing with both the first and second worms, the mounting base having a sliding groove arranged parallel to the axis of the first worm, the axle of the worm wheel being slidably mounted in the sliding groove, the end of the axle of the worm wheel being constrained and mounted in the sliding groove, a gripping disc being fixedly mounted on the worm wheel, and a hooking part adapted to the hooking groove of the vehicle platform being mounted on the gripping disc.

[0007] As an improvement, the hooking part includes a roller rotatably mounted on the gripping disc, the roller being adapted to the hooking groove of the vehicle platform.

[0008] As a further improvement, a grooved wheel is rotatably mounted on the end of the worm gear, and the outer surface of the grooved wheel is provided with an annular groove that is adapted to the sliding groove.

[0009] As a further improvement, the side of the groove away from the worm gear is provided with a receiving groove, and the rim of the grooved wheel away from the worm gear is located in the receiving groove.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are:

[0011] (1) The gripping disc of this utility model can rotate itself under the action of the first worm and the second worm, and can also slide linearly. Compared with the traditional structure, the rotation and linear movement of the traditional gripping disc require two separate sets of power and structure, and the space height is large. However, the rotation and linear movement of the gripping disc of this utility model can be achieved by power drive on the same plane, which reduces the overall height, improves the space utilization, simplifies the structure and reduces the manufacturing cost.

[0012] (2) Since the side of the chute away from the worm gear has a receiving groove, it can prevent the groove wheel from rubbing against the surface of the elevator when it rotates, and also ensure that the bottom surface of the mounting seat is flat, so that the mounting seat can be easily installed on the elevator.

[0022] A vehicle platform storage and retrieval device, such as Figure 1 and Figure 4 As shown, the device includes a mounting base 1 mounted on the elevator 11. A first worm 2 and a second worm 3, arranged in parallel, are rotatably mounted on the mounting base 1. The first worm 2 and the second worm 3 have the same direction of rotation, either left-handed or right-handed. The first worm 2 is connected to a first power mechanism, and the second worm 3 is connected to a second power mechanism. The first and second power mechanisms are respectively powered by corresponding electric motors. A worm wheel 4, meshing with both the first worm 2 and the second worm 3, is rotatably mounted on the mounting base 1. The mounting base 1 has a groove 9 parallel to the axis of the first worm 2. The axle 7 of the worm wheel 4 is slidably mounted within the groove 9, and the end of the axle 7 of the worm wheel 4 is constrained within the groove 9. This allows the worm wheel 4 to both rotate around its axle 7 and slide horizontally along the groove 9. Specifically, as shown... Figure 2 and Figure 3As shown, a grooved wheel 8 is rotatably mounted on the end of the worm gear 4. The outer surface of the grooved wheel 8 is provided with an annular groove, which is adapted to the sliding groove 9. That is, the width of the sliding groove 9 is approximately equal to the diameter of the bottom of the annular groove. A receiving groove 10 is provided on the side of the sliding groove 9 away from the worm gear 4. The rim of the grooved wheel 8 away from the worm gear 4 is located in the receiving groove 10. This ensures that the grooved wheel 8 does not rub against the surface of the elevator 11 when it rotates, and also ensures that the bottom surface of the mounting base 1 is flat, so that the mounting base 1 can be easily installed on the elevator 11. A gripping disc 5 is fixedly mounted on the worm gear 4. A hooking part adapted to the hooking groove of the car platform 12 is installed on the gripping disc 5. The hooking part includes a roller 6 rotatably mounted on the gripping disc 5. The roller 6 is adapted to the hooking groove of the car platform 12. When the car platform 12 is stored or retrieved, it can ensure that the hooking part can smoothly enter and exit the hooking groove.

[0023] In this embodiment of the utility model, the gripping disk 5 can rotate under the action of the first worm 2 and the second worm 3, and can also slide linearly, which reduces the overall height, improves space utilization, simplifies the structure, and reduces manufacturing costs.

[0024] like Figure 4 As shown, the following describes the usage process using the right-hand rotation of the first worm 2 and the second worm 3 as an example.

[0025] Car retrieval process:

[0026] 1. The first worm 2 and the second worm 3 run at the same speed. The first worm 2 rotates counterclockwise and the second worm 3 rotates counterclockwise. At this time, the worm wheel 4 does not rotate, but only produces a straight line motion to the right, moving towards the position of the vehicle platform 12.

[0027] 2. When the position reaches the designated point where the vehicle platform 12 can be hooked, the movement of the first worm gear 2 and the second worm gear 3 will both stop.

[0028] 3. At this time, the first worm 2 rotates counterclockwise and the second worm 3 rotates clockwise, maintaining the same speed. At this time, the worm wheel 4 and the gripping disk 5 rotate clockwise, and the horizontal left and right positions of the worm wheel 4 remain unchanged.

[0029] 4. When the hook part is fully inserted into the hook groove on one side of the vehicle platform 12, the first worm 2 and the second worm 3 stop running;

[0030] 5. The first worm 2 and the second worm 3 rotate clockwise at the same speed. The worm wheel 4 and the gripping disc 5 do not rotate, but move laterally to the left to hook the car carrier plate 12 to the middle position, that is, onto the lateral moving trolley or the elevator 11, thus completing the car retrieval process.

[0031] Parking process:

[0032] 1. The first worm 2 and the second worm 3 run at the same speed. The first worm 2 rotates counterclockwise and the second worm 3 rotates counterclockwise. The worm wheel 4 does not rotate but only produces a straight line motion to the right, which pushes the vehicle platform 12 to move towards the parking space.

[0033] 2. When the position reaches the designated point where the vehicle platform 12 can be hooked, the movement of the first worm gear 2 and the second worm gear 3 will both stop.

[0034] 3. At this time, the first worm 2 rotates counterclockwise and the second worm 3 rotates clockwise, maintaining the same speed. At this time, the worm wheel 4 and the gripping disk 5 rotate clockwise, and the horizontal left and right positions of the worm wheel 4 remain unchanged.

[0035] 4. When the hook part is completely disengaged from the hook groove on one side of the vehicle platform 12, the first worm 2 and the second worm 3 stop running;

[0036] 5. The first worm 2 and the second worm 3 rotate clockwise at the same speed. The worm wheel 4 and the gripping disk 5 do not rotate, but move laterally to the left. The worm wheel 4 returns to the middle position, that is, it moves onto the trolley or the elevator 11, completing the storage process.

[0037] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
