Description

Technical Field

[0001] The present invention relates to the technical field of parking equipment, and particularly relates to an underground circular three-dimensional intelligent garage. Background Art

[0002] Urban land resources are becoming increasingly scarce, while the number of residents' motor vehicles is increasing day by day, resulting in the current parking difficulty becoming a widespread urban problem. The commonly used flat parking lots at present have large floor areas for parking spaces, low space utilization efficiency, high difficulty in finding parking spaces, and narrow channels for vehicles to drive in the parking lot, and it is easy to have accidents such as scratches during the moving process. Obviously, it can no longer meet the actual parking needs.

[0003] To solve the problem of the utilization of the current parking space, a new parking mode of three-dimensional garages has been gradually proposed, which can make more effective use of space, and is particularly suitable for urban areas where the ground parking space is scarce, the available area of the underground space is small, and it is inconvenient to build large-scale underground parking lots. However, there are many design defects in the structures of the existing three-dimensional garages, resulting in unreasonable vehicle dispatching strategies. For example, a cylindrical three-dimensional automatic parking lot proposed in the invention patent with the publication number CN 215291722 U only has a circle of parking spaces, with limited parking quantity and insufficient space utilization rate.

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

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

[0006] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

For example, it can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The present invention provides an underground circular three-dimensional intelligent garage, which is located below the ground floor 19, is generally cylindrical in shape, and vehicles can be accessed and stored through an entrance on the ground. It makes full use of the underground space to construct a parking area with a huge capacity, is suitable for areas with scarce land resources such as the city center, and can effectively improve the parking efficiency in high-density spaces.

[0037] Specifically, as Figures 1-3 , the main components of the garage include a support frame, a parking platform, a vertical lifting system 4, an AGV trolley track device 7 and an AGV self-propelled transportation device. The support frame is used to support the parking platform, the parking platform has parking spaces, the vertical lifting system 4 is used for vertical transfer of vehicles, and the AGV self-propelled transportation device is used to transfer vehicles within a plane by using the AGV trolley track device 7.

[0038] Among them:

[0039] (1) Support frame:

[0040] The support frame is generally circular in shape and includes columns 13, cross beams 14 and a circular barrel wall 10, which can be concrete components or steel components, and is responsible for bearing the parking platform, the vertical lifting system 4 and the structural dead load, etc. As Figure 1 , the columns 13 are evenly distributed circumferentially and are arranged vertically, the cross beams 14 are fixed to the columns 13 and are arranged radially outward, and the circular barrel wall 10 is located outside the cross beams 14. The columns 13 are arranged in the gap part of the inner ring parking platform parking spaces, effectively utilizing the spare area outside the annular parking platform parking spaces. The circular barrel wall 10 and the water-facing surface of the ground floor 19 are paved with a PVC waterproof membrane to block the infiltration of groundwater.

[0041] The support frame includes multiple layers of cross beams 14 inside, which are used to support multiple layers of parking platforms, as Figure 1The embodiments include two floors of parking platforms. Of course, more floors of parking platforms can also be set according to the actual use range of the underground space.

[0042] In some embodiments, the columns 13 are made of cast-in-place reinforced concrete, and embedded parts with connection structures are buried at corresponding positions on each floor. The cross beams 14 are made of steel member beams, and the inner ring parking platform 2 is made of a steel member flat plate, and the steel members are connected to the column embedded parts by bolt connection.

[0043] (2) Parking platform:

[0044] Each floor of the parking platform includes a fixed inner ring parking platform 2 and a rotatable outer ring parking platform 3. Both the inner ring parking platform 2 and the outer ring parking platform 3 are supported on the cross beam 14. The outer side of the outer ring parking platform 3 is inserted into the inner side of the circular barrel wall 10. An inner ring parking platform support 5 is arranged on the outer side of the bottom of the inner ring parking platform 2, and the inner ring parking platform support 5 is located on the cross beam 14. An outer ring parking platform sliding support 21 is arranged on the inner side of the bottom of the outer ring parking platform 3, and the outer ring parking platform sliding support 21 is located on the cross beam 14. The supports can increase the load capacity of the inner ring parking platform 2 and the outer ring parking platform 3. The sliding surface of the outer ring parking platform sliding support 21 can be made of PTFE material, and a limiter is installed to limit the horizontal and vertical displacements within the plane of the sliding plate. The outer ring parking platform sliding support 21 is welded to the cross beam 14 of each floor of the outer ring parking platform, and rollers are installed at corresponding positions on the bottom of each floor of the outer ring parking platform 3 to reduce the friction force, so that the resistance of the outer ring parking platform 3 can be minimized during the operation of the drive system, reducing energy consumption.

[0045] Radially arranged parking spaces and transportation channels 8 are provided on the inner ring parking platform 2. The inner ring parking platform 2 is fixed within the support frame and does not rotate. 1 to 3 transportation channels 8 can be set on each floor to ensure that vehicles can be transported between the outer ring parking platform 3 and the lifting platform 9. The more transportation channels there are, the fewer the number of inner ring parking spaces, but the smaller the rotation angle of the outer ring, which can reduce energy consumption to a certain extent.

[0046] Radially arranged parking spaces are provided on the outer ring parking platform 3. The inner side of the outer ring parking platform 3 is slidably connected to the outer side of the inner ring parking platform 2 through guide rails, and the outer side of the outer ring parking platform 3 is meshed and connected to the inner side of the circular barrel wall 10 on the outer side of the support frame through a gear set and can rotate. Further, as Figure 1 , the gear set includes a pinion 22 and a large gear 23. The pinion 22 is installed at 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 circular barrel wall 10 and meshes with the pinion 22 to form an outer ring parking platform drive system 6. After the outer ring parking platform drive system 6 is started, the pinion 22 rotates annularly 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 guide rails and platform gaps at the gaps should be controlled within 3 cm to prevent accidents during the operation of the clamping AGV self - transport device.

[0048] The bottom plate of the parking platform is spliced by a steel member framework. Each parking space and its surrounding members form a whole, which is connected into an overall frame structure through bolts at the overlapping parts, and the compressive and bending resistance of the parking platform is strengthened by steel cross - beams.

[0049] (3) Vertical lifting system 4:

[0050] Inside the inner parking platform 2 is a vertical lifting passage, and a vertical lifting system 4 with a lifting platform 9 is provided. The vertical lifting system 4 includes a winch 11, a gantry 12, a steel wire rope 15 and a lifting platform 9. The gantry 12 is fixed on the ground layer 19 and spans above the lifting passage, with a horizontal beam at the top. The winch 11 is arranged on the horizontal beam of the gantry 12. The steel wire rope 15 is wound on the winch 11 and connected to the lifting platform 9. Through the winding action of the winch 11, the steel wire rope 15 drives the lifting platform 9 to lift between floors. In some embodiments, 4 winches 11 can be used in combination for operation.

[0051] In addition, vertical guide columns 16 are arranged in the lifting passage. The guide columns 16 are located outside the lifting platform 9. The outer periphery of the lifting platform 9 is provided with ball sliders and is located in the vertical grooves arranged inside the guide columns 16, which play a guiding role during the up - and - down lifting process of the lifting platform 9 to ensure the stable operation of the lifting platform 9.

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

[0053] The garage also includes an AGV car track device 7 and an AGV self - transport device. The AGV car track device 7 is arranged on the lifting platform 9, on the parking spaces of the inner parking platform 2 and the outer parking platform 3, and on the transportation passage 8 of the inner parking platform 2. A stopper 17 and a sensor 18 are arranged on each parking space to sense the parking state of the parking space and ensure the safe parking of the vehicle, and cooperate with the movement of the AGV self - transport device. In addition, the AGV car track device 7 is a stainless - steel guide rail, which is fixed in the center of each parking space in each parking space direction by bolt connection. A guide rail is longitudinally arranged from the center of the circle to the center of each parking space in each parking space direction to ensure that the direction of the AGV self - transport device will not deviate, and magnetic tapes are pasted on the guide rail to distinguish stations by different magnetic arrangements and guide the AGV self - transport device to work smoothly.

[0054] The AGV self - transporting device in the present invention adopts an existing clamping - type AGV self - transporting device, including an electromagnetic sensing device, a mechanical clamping mechanism, a wheeled mobile system, and a track positioning device. The electromagnetic sensing device is used to sense the guide rail magnetic stripe landmark, so as to achieve automatic driving. The mechanical clamping mechanism is used to lift the vehicle for movement. The wheeled mobile device can go straight or rotate in place by itself, and is used to transport the vehicle to the designated parking space. The track positioning device docks with the trolley track to ensure that the direction will not deviate, avoiding situations such as scratching of the user's vehicle.

[0055] The above - mentioned garage can be controlled and operated by an intelligent control system. The system includes a sensing device (installed in the stopper), an information storage system, and a path planning and interaction system to realize automatic identification and access of vehicles. Among them, the sensing device is used to sense the availability of parking spaces. The information storage system is used to store information such as the parking space number where the vehicle is parked and the vehicle bound to the user's account. The path planning and interaction system is used to calculate the parking and retrieval paths and send instructions to the clamping - type AGV self - transporting device. When parking, the system selects an available target parking space according to the priority. The priority is: upper - layer inner - ring parking space > lower - layer inner - ring parking space > upper - layer outer - ring parking space > lower - layer outer - ring parking space. This priority can maximize the reduction of the rotation frequency of the outer - ring parking platform, reduce energy consumption, and extend the service life of the drive system of the outer - ring parking platform.

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

[0057] User management module, which provides functions such as binding vehicle information for users, recording parking fees, automatic deduction of fees, integral reward system, and parking information query.

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

[0059] Flow prediction module, which records and statistically analyzes the number of vehicle entries and exits at the garage entrance and exit in real - time, analyzes the traffic peaks and troughs, calculates the queuing time during peak periods, and automatically gives early warnings of traffic peaks and troughs to prompt users to park at off - peak times.

[0060] In some embodiments, a safety guarantee system can also be constructed. Signs are set at the garage entrance and exit to remind passengers to get off first. After the driver enters and parks the car, he / she needs to return to the garage entrance and exit and click the confirm parking button on the interactive tablet before the parking system can operate, avoiding dangerous situations such as the vehicle occupants not leaving when the system is running. An alarm button is installed at each parking space, and an all - around monitoring device is installed to prevent accidents.

[0061] The working process of the present invention is as follows:

[0062] (1) Parking working process:

[0063] Before operation, the lifting platform 9 is located at the top layer of the vertical lifting system 4, i.e., the ground floor. The clamping type AGV self-transporting device is located on the lifting platform 9. The driver uses the interactive tablet or scans the code to enter the small program at the garage entrance and exit to log in to the account and send a parking application. The intelligent control system searches for available parking spaces and approves the parking request. The vehicle passengers get off first, and the vehicle drives into the lifting platform 9 from the garage entrance and exit. The driver leaves the vehicle and clicks to confirm parking at the garage entrance and exit. The clamping type AGV self-transporting device starts to operate. The mechanical clamping mechanism uses 8 claws to clamp 4 car tires through the motor-driven lead screw. The intelligent control system calculates the target path of the available parking space and sends instructions to the vertical lifting system 4 and the AGV self-transporting device. If the available parking space is on the inner ring parking platform 2, the vertical lifting system 4 transports the lifting platform 9 to the target layer through the instruction. The AGV self-transporting device rotates in place to the target direction through the instruction and docks with the AGV car track device 7, and moves towards the target parking space. After arriving, it retracts the mechanical claws, puts down the vehicle, and then moves to the lifting platform 9 by itself. If the available parking space is on the outer ring parking platform 3, the vertical lifting system 4 transports the lifting platform 9 to the target layer through the instruction. The AGV self-transporting device rotates in place to the transportation channel 8. The outer ring parking platform drive system 6 starts to operate, drives the outer ring parking platform 3 to align with the transportation channel 8 at the target parking space. The AGV self-transporting device rotates in place to the target direction through the instruction and docks with the AGV car track device 7, and moves towards the target parking space. After arriving, it retracts the mechanical claws, puts down the vehicle, and then moves to the lifting platform 9 by itself.

[0064] (2) Process of picking up the vehicle:

[0065] The user uses the interactive tablet or scans the code to enter the small program to send a vehicle pick-up application. The intelligent control system searches for the parking location of the target vehicle. The clamping type AGV self-transporting device runs to the position below the target vehicle through the vertical lifting platform 9 and the car guide rail 7. The mechanical clamping mechanism uses 8 claws to clamp 4 car tires through the motor-driven lead screw, and then returns to the top layer through the car guide rail 7 and the vertical lifting platform 9 and adjusts the direction so that the front of the vehicle is aligned with the exit, and sends a work completion signal to the intelligent control system. The garage entrance and exit gate opens, and the user successfully picks up the vehicle.

[0066] The present invention adopts a circular structure and a layout of two-ring parking platforms, combined with an intelligent control system, realizing efficient vehicle parking and retrieval, improving the space utilization rate, greatly improving the user experience, and at the same time reducing the operation cost.

[0067] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention belongs, according to the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
