Description

Technical Field

[0001] This utility model relates to the field of parking equipment technology, specifically to an underground circular three-dimensional intelligent parking garage. Background Technology

[0002] With increasingly scarce urban land resources and a rapidly growing number of motor vehicles, parking difficulties have become a widespread urban problem. Existing, commonly used surface parking lots have large footprints, low space utilization efficiency, difficulty in finding parking spaces, and narrow lanes, increasing the risk of accidents such as scrapes and collisions during vehicle movement. Clearly, they cannot meet actual parking demands.

[0003] To address the current parking space utilization problem, a new parking model of multi-level parking garages has been gradually proposed, which can utilize space more effectively and is particularly suitable for urban areas with scarce ground parking space, limited usable underground space, and inconvenient conditions for constructing large-scale underground parking lots. However, existing multi-level parking garages have many design flaws, resulting in unreasonable vehicle scheduling strategies. For example, the utility model patent with publication number CN 215291722 U proposes a cylindrical multi-level automated parking garage, which only has one ring of parking spaces, limiting the number of parking spaces and resulting in insufficient space utilization.

[0004] Therefore, it is necessary to propose new measures to overcome the above-mentioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide an underground circular three-dimensional intelligent parking garage to solve the problems of limited parking capacity and insufficient space utilization in existing three-dimensional parking garages.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An underground circular three-dimensional intelligent parking garage includes a circular support frame and multiple parking platforms within the support frame. Each parking platform includes a fixed inner parking platform and a rotatable outer parking platform. The inner parking platform has a vertical lifting channel and is equipped with a vertical lifting system with a lifting platform.

[0008] The inner parking platform is equipped with radially arranged parking spaces and transport channels, and the inner parking platform is fixed within the support frame.

[0009] The outer parking platform is provided with radially arranged parking spaces. The inner side of the outer parking platform is slidably connected to the outer side of the inner parking platform via guide rails. The outer side of the outer parking platform is connected to the inner side of the circular cylindrical wall of the outer side of the support frame via a gear set.

[0010] Furthermore, the support frame includes columns, beams, and the circular cylindrical wall;

[0011] The columns are arranged circumferentially, the crossbeams are fixed to the columns and arranged radially outwards, and the circular cylindrical wall is located outside the crossbeams;

[0012] Both the inner and outer parking platforms are supported on the crossbeam.

[0013] Furthermore, the vertical lifting system includes a winch, a gantry frame, wire ropes, and a lifting platform;

[0014] The gantry frame is fixed on the ground floor and spans across the lifting channel. The winch is mounted on the horizontal beam of the gantry frame, and the wire rope is wound on the winch and connected to the lifting platform.

[0015] Furthermore, a vertical guide column is provided in the lifting channel, and the guide column is located on the outside of the lifting platform;

[0016] The outer periphery of the lifting platform is provided with a ball bearing slider, which is located in a vertical groove provided inside the guide column.

[0017] Furthermore, the garage also includes an AGV trolley track device, which is installed on the lifting platform, on the parking spaces of the inner and outer parking platforms, and on the transport channel of the inner parking platform.

[0018] Furthermore, the gear set includes a pinion and a gear;

[0019] The pinion is mounted on the outer bottom of the outer ring parking platform and is equipped with a drive motor;

[0020] The large gear is fixed to the inner side of the cylindrical wall and meshes with the small gear.

[0021] Furthermore, the outer side of the outer parking platform is inserted into the inner side of the circular cylindrical wall.

[0022] Furthermore, an inner parking platform support is provided on the outer bottom of the inner parking platform, and the inner parking platform support is located on the crossbeam.

[0023] Furthermore, a sliding support for the outer parking platform is provided on the inner bottom side of the outer parking platform, and the sliding support for the outer parking platform is located on the crossbeam.

[0024] Furthermore, each of the parking spaces is equipped with a stop.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] This invention provides an underground circular intelligent parking garage with a double-ring parking platform. Compared to existing single-ring parking platforms, while increasing the garage diameter by approximately 65.8%, the number of parking spaces is increased by approximately 250%, significantly improving space utilization and profitability. Furthermore, using a clamp-type AGV (Automated Guided Vehicle) self-driving device instead of a conveyor belt reduces the difficulty of parking for drivers. The inner ring parking platform does not need to rotate, reducing system complexity and energy consumption, while also lowering the system's failure rate. Attached Figure Description

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] This utility model provides an underground circular three-dimensional intelligent parking garage, located below ground level 19. It is generally cylindrical and can be used to store and retrieve vehicles from one entrance on the ground. It makes full use of underground space to create a parking space with huge capacity. It is suitable for areas with scarce land resources such as urban centers and can effectively improve the parking efficiency of high-density spaces.

[0037] Specifically, such as Figure 1-3 The main components of the garage include a support frame, a parking platform, a vertical lifting system 4, an AGV (Automated Guided Vehicle) track device 7, and an AGV self-driving transport device. The support frame supports the parking platform, which has parking spaces. The vertical lifting system 4 is used for vertical movement of vehicles, and the AGV self-driving transport device uses the AGV track device 7 to move vehicles in a horizontal plane.

[0038] in:

[0039] (1) Supporting framework:

[0040] The supporting frame is circular in shape, including columns 13, beams 14, and a circular cylindrical wall 10. It can be made of concrete or steel and is responsible for bearing the parking platform, the vertical lifting system 4, and structural dead loads. Figure 1 The columns 13 are evenly distributed circumferentially and vertically installed. The crossbeams 14 are fixed to the columns 13 and arranged radially outwards. The circular cylindrical wall 10 is located outside the crossbeams 14. The columns 13 are positioned in the gaps between parking spaces on the inner ring parking platform, effectively utilizing the empty area outside the parking spaces of the ring parking platform. A PVC waterproof membrane is laid on the water-facing side of the circular cylindrical wall 10 and the ground layer 19 to prevent groundwater infiltration.

[0041] The supporting frame includes multiple layers of crossbeams 14 for supporting the multi-level parking platform, such as... Figure 1The embodiment includes a two-story parking platform. Of course, more stories of parking platforms can also be set up depending on the actual usage of the underground space.

[0042] In some embodiments, the column 13 is made of cast-in-place reinforced concrete, and embedded parts with connecting structures are embedded in the corresponding positions of each layer. The crossbeam 14 is made of steel beam, and the inner ring parking platform 2 is made of steel plate. The steel components are connected to the column embedded parts by bolt connection.

[0043] (2) Parking platform:

[0044] Each parking platform includes a fixed inner parking platform 2 and a rotatable outer parking platform 3, both supported by a crossbeam 14. The outer side of the outer parking platform 3 is inserted into the inner side of the circular cylindrical wall 10. An inner parking platform support 5 is provided on the outer bottom of the inner parking platform 2, located on the crossbeam 14. An outer parking platform sliding support 21 is provided on the inner bottom of the outer parking platform 3, located on the crossbeam 14. The supports increase the load-bearing capacity of the inner parking platform 2 and the outer parking platform 3. The sliding surface of the outer ring parking platform sliding support 21 can be made of PTFE material and equipped with limiters to restrict the horizontal and vertical displacement within the plane of the sliding plate. The outer ring parking platform sliding support 21 is welded to the crossbeam 14 of each layer of the outer ring parking platform. Rollers are installed at the corresponding positions at the bottom of each layer of the outer ring parking platform 3 to reduce friction, so that the outer ring parking platform 3 can minimize resistance and reduce energy consumption during the operation of the drive system.

[0045] The inner parking platform 2 is equipped with radially arranged parking spaces and transport channels 8. The inner parking platform 2 is fixed within the supporting frame and does not rotate. Each floor can have 1 to 3 transport channels 8 to ensure that vehicles can be transported between the outer parking platform 3 and the lifting platform 9. The more transport channels there are, the fewer parking spaces there are in the inner ring, but the smaller the rotation angle of the outer ring, which can reduce energy consumption to some extent.

[0046] The outer parking platform 3 has radially arranged parking spaces. The inner side of the outer parking platform 3 is slidably connected to the outer side of the inner parking platform 2 via guide rails. The outer side of the outer parking platform 3 is connected to the inner side of the circular cylindrical wall 10 on the outer side of the support frame via a gear set, and is rotatable. Further, such as... Figure 1 The gear set includes a pinion 22 and a large gear 23. The pinion 22 is mounted on the outer bottom of the outer ring parking platform 3 and is equipped with a drive motor 20. The large gear 23 is fixed to the inner side of the cylindrical wall 10 and meshes with the pinion 22, forming the outer ring parking platform drive system 6. After the outer ring parking platform drive system 6 is started, the pinion 22 rotates in a ring within the large gear 23, thereby driving the outer ring parking platform 3 to rotate synchronously.

[0047] The inner parking platform 2 and the outer parking platform 3 are not connected, but the gap between the guide rail and the platform should be controlled within 3cm to prevent accidents from happening during the operation of the clamp-type AGV self-transport device.

[0048] The parking platform base is made of steel frame components. Each parking space and its surrounding components are a whole, and the overall frame structure is formed by bolts connecting the overlapping parts. The parking platform is reinforced with steel beams to enhance its compressive and bending resistance.

[0049] (3) Vertical lifting system 4:

[0050] The inner parking platform 2 contains a vertical lifting channel and is equipped with a vertical lifting system 4 with a lifting platform 9. The vertical lifting system 4 includes a winch 11, a gantry frame 12, a wire rope 15, and the lifting platform 9. The gantry frame 12 is fixed to the ground level 19 and spans across the lifting channel, with a horizontal beam at its top. The winch 11 is mounted on the horizontal beam of the gantry frame 12, and the wire rope 15 is wound onto the winch 11 and connected to the lifting platform 9. Through the winding action of the winch 11, the wire rope 15 drives the lifting platform 9 to rise and fall between levels. In some embodiments, four winches 11 can be used in combination.

[0051] In addition, a vertical guide column 16 is provided in the lifting channel. The guide column 16 is located on the outside of the lifting platform 9. A ball bearing slider is provided on the outer periphery of the lifting platform 9 and is located in the vertical groove provided on the inner side of the guide column 16. It plays a guiding role in the up and down lifting process of the lifting platform 9 to ensure the stable operation of the lifting platform 9.

[0052] (4) AGV trolley track device 7 and AGV self-transport device:

[0053] The garage also includes an AGV (Automated Guided Vehicle) track device 7 and an AGV self-driving transport device. The AGV track device 7 is installed on the lifting platform 9, on the parking spaces of the inner parking platform 2 and the outer parking platform 3, and on the transport channel 8 of the inner parking platform 2. Each parking space is equipped with a stop device 17 and a sensor 18 to sense the parking status of the parking space and ensure the safe parking of the vehicle, coordinating with the movement of the AGV self-driving transport device. In addition, the AGV track device 7 is a stainless steel guide rail, which is bolted to the center of each parking space in each direction. A guide rail is arranged longitudinally from the center of each parking space in each direction to ensure that the AGV self-driving transport device does not deviate in direction. Magnetic tape is attached to the guide rail, and different magnetic combinations are used to distinguish the stations and guide the AGV self-driving transport device to work smoothly.

[0054] The AGV self-driving device in this invention adopts an existing clamping-type AGV self-driving device, including an electromagnetic sensing device, a mechanical clamping mechanism, a wheeled movement system, and a track positioning device. The electromagnetic sensing device senses the magnetic strip markers on the guide rail, thereby enabling automatic movement. The mechanical clamping mechanism lifts the vehicle for movement. The wheeled movement device can move straight or rotate in place to transport the vehicle to a designated parking space. The track positioning device aligns with the vehicle's track to ensure directional accuracy and prevent scratches or other damage to the user's vehicle.

[0055] The aforementioned parking garage can be controlled by an intelligent control system, which includes sensors (installed in the stop devices), an information storage system, and a path planning and interaction system to achieve automatic vehicle identification and retrieval. The sensors detect parking space availability, the information storage system stores information such as the vehicle's parking space number and the vehicle linked to the user's account, and the path planning and interaction system calculates the parking and retrieval path and sends instructions to the clamp-type AGV self-propelled transport device. When parking, the system selects an available target parking space based on priority: upper inner ring parking spaces > lower inner ring parking spaces > upper outer ring parking spaces > lower outer ring parking spaces. This priority minimizes the rotation frequency of the outer ring parking platform, reducing energy consumption and extending the service life of the outer ring parking platform's drive system.

[0056] In addition, the intelligent control system needs to include the following modules:

[0057] The user management module provides users with functions such as binding vehicle information, recording parking fees, automatic deduction, points reward system, and parking information query;

[0058] The license plate recognition module consists of a high-definition camera, OCR text recognition, and a database system. It is used to automatically recognize vehicle license plate information, record vehicle entry and exit information, and facilitate vehicle management.

[0059] The traffic prediction module records and counts the number of vehicles entering and exiting the garage entrance and exit in real time, analyzes traffic peaks and troughs, calculates queuing time during peak hours, and automatically issues early warnings for traffic peaks and troughs to remind users to park during off-peak hours.

[0060] In some embodiments, a safety system can also be built, with signs at the garage entrance and exit to remind passengers to get off the car first. After the driver enters and parks the car, he / she must return to the garage entrance and exit and click the parking confirmation button on the interactive whiteboard before the parking system can be activated. This avoids dangerous situations such as passengers not having left the car while it is in operation. An alarm button and a comprehensive monitoring device are also installed in each parking space to prevent accidents.

[0061] The working process of this utility model is as follows:

[0062] (1) Parking process:

[0063] Before operation, the lifting platform 9 is located on the top floor of the vertical lifting system 4, i.e., the ground floor. The clamping AGV self-transport device is located on the lifting platform 9. The driver uses an interactive tablet or scans a QR code at the garage entrance to log in to the mini-program and send a parking application. The intelligent control system finds available parking spaces and approves the parking request. Passengers disembark first, and the vehicle drives into the lifting platform 9 from the garage entrance. The driver leaves the vehicle and clicks to confirm parking at the garage entrance. The clamping AGV self-transport device then starts operating. The mechanical clamping mechanism uses eight jaws to clamp four car tires via a motor-driven lead screw. The intelligent control system calculates the target path for the available parking space and sends instructions to the vertical lifting system 4 and the AGV self-transport device. If the available parking space is on the inner parking platform 2, the vertical lifting system... 4. The lifting platform 9 is transported to the target floor by command. The AGV self-transport device rotates in place to the target direction and docks with the AGV trolley track device 7, moves to the target parking space, retracts the mechanical grippers after positioning, lowers the vehicle, and then moves to the lifting platform 9 by itself. If the vacant parking space is on the outer parking platform 3, the vertical lifting system 4 transports the lifting platform 9 to the target floor by command. The AGV self-transport device rotates in place to the transport channel 8. The outer parking platform drive system 6 starts running, driving the outer parking platform 3 to the target parking space and aligning it with the transport channel 8. The AGV self-transport device rotates in place to the target direction and docks with the AGV trolley track device 7, moves to the target parking space, retracts the mechanical grippers after positioning, lowers the vehicle, and then moves to the lifting platform 9 by itself.

[0064] (2) Vehicle retrieval process:

[0065] Users can use an interactive tablet or scan a QR code to access the mini-program and submit a vehicle retrieval request. The intelligent control system locates the target vehicle's parking position. The clamping AGV self-propelled transport device moves to the bottom of the target vehicle via the vertical lifting platform 9 and the trolley guide rail 7. The mechanical clamping mechanism uses a motor-driven lead screw to clamp the four car tires with eight grippers. Then, it returns to the top floor via the trolley guide rail 7 and the vertical lifting platform 9 and adjusts its direction so that the front of the vehicle is aligned with the exit. It sends a work completion signal to the intelligent control system, and the garage entrance gate opens, allowing the user to successfully retrieve the vehicle.

[0066] This utility model adopts a circular structure and a two-ring parking platform layout, combined with an intelligent control system, to achieve efficient vehicle parking and retrieval, improve space utilization, significantly enhance user experience, and reduce operating costs.

[0067] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the concept of this invention.
