Description

Technical Field

[0001] The present invention relates to the technical field of parking facilities, in particular to an annular three-dimensional parking garage. Background Art

[0002] At present, the main parking methods in various places are still ground parking spaces and underground parking spaces, and this method is difficult to resist the impact of floods and disasters, especially in recent years when natural disasters have occurred frequently. For example, in the summer of 2021, Zhengzhou suffered from heavy rain disasters. The number of vehicles damaged in the heavy rain in Zhengzhou was huge, and the losses were serious. The multi-story parking garage can effectively avoid the occurrence of such losses.

[0003] At the same time, multi-story parking garages have been adopted in many places, such as large shopping malls, hospitals, parks, commercial districts, and residential communities, due to their advantages such as small footprint, high degree of automation, and easy management. Existing multi-story parking garages mainly include: lifting and transverse movement, vertical circulation, horizontal circulation, flat-plane movement, aisle stacking, and simple lifting types. However, in most cases, multi-story parking garages have only one access point, and vehicles must wait for the previous vehicle to be fully stored before the next vehicle can be stored. This results in long access times. Furthermore, multi-story parking garages have limited parking capacity and low space utilization, which has hindered their widespread promotion and application. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a circular multi-story parking garage, which is designed from the perspective of its structure and the way of parking and retrieval, effectively utilizing the parking space, with a high parking space density, and realizing simultaneous parking and retrieval from all directions of the ring, thereby solving the problems of limited parking spaces and long parking and retrieval time in existing parking garages.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a ring-shaped multi-story parking garage includes: an entry and exit vehicle layer, which is connected to the external road and is used for vehicle entry and exit and storage and retrieval; a storage layer, which has multiple layers and is used to store vehicles, each storage layer includes multiple storage units, and the multiple storage units on each layer are arranged radially in a ring shape, and each storage layer is aligned longitudinally; a lifting device, which can be lifted and lowered longitudinally along the storage layer, and each storage unit is provided with at least one lifting device for transporting the vehicle to the storage layer, and the structure of the lifting device adopts existing technology.

[0006] By adopting this technical solution, multiple storage units are arranged in a circular radial shape, which improves the density of parking spaces in the three-dimensional parking garage, increases the number of parking spaces per unit area of the parking garage, and effectively utilizes the parking space. At the same time, at least one lifting device is set in each storage unit. The increase of lifting devices enables simultaneous storage and retrieval of cars from all directions of the ring, shortening the problem of long queuing time for parking and retrieval.

[0007] Preferably, the vehicle entry and exit layer includes an entry and exit lane, multiple first turntables, multiple first trailers and a trailer storage area; the entry and exit lane is connected to the external road, and multiple first turntables are respectively arranged on the entry and exit lanes, each first turntable is configured corresponding to each lifting device, and each first turntable is equipped with a first trailer for towing the vehicle in or out of the lifting device. The trailer storage area is located in the middle of the three-dimensional parking garage and is surrounded by the entry and exit lanes. It is a place for all the first trailers located around the trailer storage area to park when they are not in operation. The first trailer can slide along the trailer storage area, the first turntable and the lifting device to tow the vehicle in or out of the lifting device.

[0008] In this technical solution, the first rotating platform is used to adjust the direction of the car so that the car is aligned with the lifting device to facilitate towing the car in or out, replacing the driver's manual reversing operation and saving car storage and retrieval time. Multiple storage units are arranged in a circular radial shape, so that a trailer storage area can be set up in the center of the parking garage to realize towing the car in and out of the corresponding multiple lifting devices, greatly improving the utilization of space and saving time for storing and retrieving the car.

[0009] Preferably, the storage unit includes a preset space for a lifting device, a plurality of parking spaces arranged side by side, a movable passage and a movable platform; the preset space for the lifting device is arranged side by side with the parking space, a third wheel brake mechanism is provided on the parking space, and the third wheel brake mechanism has the same structure as the first wheel brake mechanism; the movable passage is located on one side of the arrangement direction of the plurality of parking spaces; the movable platform is movably provided on the movable passage; the movable platform can move along the length direction of the movable passage; a tugwheel and a drive device are provided at the bottom of the movable platform, or movement is achieved by a screw nut or a gear rack; the movable platform can transport the car carried up by the lifting device to the parking space; a movable second trailer is provided on the mobile platform; the second trailer has the same structure as the first trailer or can be realized by using other existing technologies; the second trailer can move along the movable platform and the parking space to tow the car into or out of the parking space.

[0010] In this technical solution, the space utilization rate is improved by adopting the parking spaces arranged side by side. In addition, the movement of the mobile platform on the moving channel realizes the rapid parking and retrieval of the car in each storage unit parking space, thereby improving the efficiency of parking and retrieving the car.

[0011] Preferably, it also includes a dispatching system, which is arranged in the middle of the three-dimensional parking garage and is surrounded by storage layers. The dispatching system is used to dispatch vehicles from one storage unit to another; the dispatching system includes a lifting platform, a support frame, a lifting platform drive mechanism and multiple fixing mechanisms. The support frame is vertically fixed on the vehicle entry and exit layer, the lifting platform drive mechanism is transmission-connected to the lifting platform, and the lifting platform is lifted up and down along the fixed frame under the drive of the lifting platform drive mechanism. The lifting platform drive mechanism can be realized by hoisting or by installing a lifting and telescopic device under the lifting platform. Multiple fixing mechanisms are fixed on the support frame, and each fixing mechanism is arranged corresponding to the storage unit on each layer, and is used to fix the lifting platform support at the same layer of each storage unit.

[0012] By adopting the dispatching system, the dispatching and turnover of vehicles between various storage units are realized, and the intercommunication between independent storage units is realized. When the lifting device of a certain column of storage units fails, or the storage and retrieval of vehicles in a certain column of storage units is blocked, the dispatching system can dispatch the vehicles to other columns of storage units for lifting and retrieval. During the peak period of storage and retrieval, the dispatching system can assist the lifting devices of each storage unit to carry out lifting and transportation. The above functions effectively alleviate the problem of storage and retrieval congestion during peak periods and shorten the time for storage and retrieval.

[0013] Preferably, the lifting platform includes a platform and a second rotating platform, the second rotating platform is rotatably arranged above the platform, and a plurality of lifting ears are arranged around the upper surface of the platform, and the lifting ears are connected to the lifting platform driving mechanism to realize the lifting and lowering of the lifting platform by the driving mechanism. The lower surface of the platform is cross-arranged with supporting main beams and supporting auxiliary beams, and locking switches are provided at both ends of the supporting main beams for locking the supporting main beams to the fixing mechanism. The locking switch can be hydraulically controlled, or spring controlled or mechanically controlled, which is well known to those skilled in the art and will not be repeated here. A second trailer moving guide rail for guiding the trailer is provided on the platform, and a second wheel brake mechanism is provided on the upper surface of the second rotating platform. The second wheel brake mechanism has the same structure as the first wheel brake mechanism.

[0014] By adopting this technical solution, the setting of the second turntable can better realize the scheduling of vehicles between various storage units. Because the storage units on each floor are arranged in a circular radial shape, the second turntable can realize the rotation of the carrying vehicle to rotate it to other storage units, and then lift and access it; the lifting platform adopts a hoisting method, which is more cost-effective and suitable for high-rise multi-story parking garages. When lifting by hoisting, stability in the stopped state is more necessary. Therefore, this technical solution is provided with a supporting main beam and a supporting auxiliary beam, and locking switches are provided at both ends of the supporting main beam, which improves the stability of the lifting platform and ensures the safety of the scheduling system.

[0015] Preferably, the fixing mechanism includes a connecting plate, a locking member and a positioning member. The connecting plate is fixedly connected to the support frame. A hole that is compatible with the lifting platform is opened in the center of the connecting plate. A third trailer moving guide rail for guiding the trailer is provided on the connecting plate. The locking member and the positioning member are fixed on the support frame. The locking member is compatible with the locking switch, and the positioning member is compatible with the supporting auxiliary beam. When the lifting platform is fixed to the preset storage unit, it is positioned by the supporting auxiliary beam and the positioning member, and the lifting platform is fixed to the fixing mechanism by the locking switch.

[0016] By adopting the above technical solution, the connecting plate realizes the bridge connection between the lifting platform and the storage units, ensuring the safety of the vehicle moving between the lifting platform and the storage units. In addition, a specific technical solution for positioning and locking between the lifting platform and the support frame is given, which improves the safety performance of the lifting platform during operation.

[0017] Preferably, the first rotating platform includes a rotating platform, a rotating shaft, a rotating drive mechanism, a driven wheel, a first trailer moving guide rail, a guardrail and a first wheel braking mechanism; the rotating shaft is fixed under the rotating platform and drives the rotating platform to rotate through the drive of the rotating drive mechanism, the driven wheel is installed along the circumference of the lower surface of the rotating platform, the guardrail is fixed on the periphery of the upper surface of the rotating platform, the first wheel braking mechanism and the first trailer moving guide rail are both arranged on the upper surface of the rotating platform, and the first trailer moving guide rail is arranged parallel to the inner side of the first wheel braking mechanism.

[0018] By adopting this technical solution, stable rotation of the first turntable is achieved. At the same time, the first wheel braking mechanism realizes braking of the vehicle parked on the first turntable, avoiding the risk of the vehicle moving on the turntable. In addition, the guardrail further improves safety. The setting of the first trailer moving guide rail ensures the safety of the vehicle during the towing process and improves the towing speed.

[0019] Preferably, the first wheel braking mechanism includes a pair of first anti-slip blocks and a pair of brake blocks that can position and clamp the wheel, the brake blocks include a fixed anti-slip block, a first rotating shaft, a first movable anti-slip block that can rotate around the first rotating shaft, a second rotating shaft, a movable anti-slip block that can rotate around the second rotating shaft and a telescopic device; a telescopic device is provided below the junction of the first movable anti-slip block and the second movable anti-slip block, and when the telescopic device is raised, the first movable anti-slip block and the second movable anti-slip block are flush with the fixed anti-slip block.

[0020] By adopting this technical solution, external braking of the vehicle is achieved, the stability of the vehicle on the first turntable is achieved, and the occurrence of safety accidents is avoided when the first turntable rotates. This structure is simple and reliable, low-cost, and suitable for mass production.

[0021] Preferably, the first trailer includes a front-wheel trailer and a rear-wheel trailer, which are telescopically connected to each other for adjusting the distance between the front-wheel trailer and the rear-wheel trailer to accommodate vehicles with different wheelbases. The telescopicity can be achieved through a hydraulic cylinder or a screw thread connection. Both the front-wheel trailer and the rear-wheel trailer are provided with a positioning and clamping mechanism for clamping tires, a lifting mechanism for positioning and clamping corresponding tires, and a trailer driving mechanism for lifting the vehicle.

[0022] Preferably, the positioning clamping mechanism includes two clamping jaws, a positioning radar and a telescopic mechanism for controlling the opening and closing of the clamping jaws; gaps for accommodating tires are provided on both sides of the front-wheel trailer and the rear-wheel trailer, the clamping jaws are respectively provided at the gaps on the left and right sides of the first trailer, and the telescopic mechanism is provided between the two clamping jaws.

[0023] This technical solution provides a solution for towing vehicles. Unlike the existing technology, the first trailer of this technical solution realizes a series of actions of positioning, clamping, lifting and towing the vehicle through a simple structure. It can also adapt to vehicles with various wheelbases and has good versatility.

[0025] Most of the parking spaces in existing multi-story parking garages are not fixed, making it impossible to charge new energy vehicles in the multi-story parking garages, and rarely considering the storage of large SUVs and MPVs. However, the structural setting based on the technical solution can realize the charging of new energy vehicles and the storage of large SUVs and MPVs.

[0064] The working process of this embodiment is as follows: a vehicle enters the in-and-out lane 11 of the in-and-out vehicle layer 1 from the external road and directly enters the first turntable 12, and the driver can get off the vehicle. The first wheel brake mechanism 127 on the first turntable 12 starts to operate, the telescopic device 1278 retracts, and the first movable anti-slip block 1275 and the second movable anti-slip block 1277 rotate around the first rotation axis 1274 and the second rotation axis 1276 under the pressure of the vehicle's own weight, forming a pit to complete the braking of the wheels to ensure the safety and stability of the vehicle on the first turntable 12. The first turntable 12 is then rotated to be aligned with the lifting device 3, and the lifting device 3 is lowered to one floor. The first trailer 13 of the trailer storage area 14 corresponding to the first turntable 12 starts to run and is driven by the trailer driving mechanism 135 to run to the first turntable 12, the distance between the front wheel trailer 131 and the rear wheel trailer 132 is adjusted to ensure that the gaps on both sides of the front wheel trailer 131 and the rear wheel trailer 132 are aligned with the tires. This distance is detected and fed back by the positioning radar 1332. After the first trailer 13 is in place, the positioning clamping mechanism 133 starts to work, and the opening and closing of the two clamping claws 1331 are controlled by the telescopic mechanism 1333. When the telescopic mechanism 1333 is retracted, the two clamping claws 1331 are closed under the restriction of the mechanism, and the tires are lifted while closing. Under the drive of the trailer driving mechanism 135, the vehicle on the first rotating platform 12 is towed to the lifting device 3. After it is in place, when the telescopic mechanism 1333 is extended, the two clamping claws 1331 are opened and returned to the initial position, and the first trailer 13 returns to the trailer storage area 14. The vehicle is lifted by the lifting device 3 to the storage unit 21 on the designated storage layer 2. The mobile platform 214 on the movable channel 213 moves to the preset empty space 211 of the lifting device. At this time, the lifting device 3 is parked on the preset empty space 211 of the lifting device, and the mobile platform 214 is aligned with the lifting device 3. The second trailer 216 on the mobile platform 214 tows the vehicle in the lifting device 3 onto the mobile platform 214. The mobile platform 214 moves to the designated parking space 212. The second trailer 216 then tows the vehicle to the parking space 212. The second trailer 216 then withdraws to the mobile platform 214. The working principle of the second trailer 216 here is the same as that of the first trailer 13. The third wheel brake mechanism 215 on the parking space 212 starts to operate, fixing the wheels. The principle is the same as that of the first wheel brake mechanism 127, and the parking is completed.

[0066] Example 2

[0067] The difference between this embodiment and embodiment 1 is that, referring to Figure 11-14 The annular three-dimensional parking garage also includes a dispatching system 4, which is arranged in the middle of the three-dimensional parking garage and is surrounded by the storage layer 2. The dispatching system 4 is used to dispatch vehicles from one storage unit 21 to another storage unit 21; the dispatching system 4 includes a lifting platform 41, a support frame 42, a lifting platform driving mechanism 43 and twenty-four fixing mechanisms 44 (because the entire annular three-dimensional parking garage has twenty-five floors, and the lifting platform 41 starts from the second floor, so there are twenty-four fixing mechanisms 44). The support frame 42 is vertically fixed on the vehicle entry and exit layer 1, and the lifting platform driving mechanism 43 is connected to the lifting platform 41 in a transmission manner. The lifting platform 41 is driven by the lifting platform driving mechanism 43 to move up and down along the fixed frame. The lifting platform driving mechanism 43 adopts a hoisting method. Figure 1 A plurality of fixing mechanisms 44 are fixed on the support frame 42 , and each fixing mechanism 44 is correspondingly provided to a storage unit 21 on each layer, and is used to support and fix the lifting platform 41 at a position on the same layer of each storage unit 21 .

[0068] Reference Figure 13-14 The lifting platform 41 includes a platform 411 and a second rotating platform 412. The second rotating platform 412 is rotatably arranged above the platform 411. A plurality of lifting ears 413 are arranged around the upper surface of the platform 411. The lifting ears 413 are connected to the lifting platform driving mechanism 43. Figure 1, so as to realize the lifting and lowering of the lifting platform 41 by the lifting platform driving mechanism 43, the lower surface of the platform 411 is cross-arranged with a supporting main beam 414 and a supporting auxiliary beam 415, and a locking switch 416 is provided at both ends of the supporting main beam 414 for locking the supporting main beam 414 to the fixing mechanism 44. The locking switch 416 can be hydraulically controlled, or spring controlled or mechanically controlled. A second trailer moving guide rail 417 and a second wheel brake mechanism 418 are provided on the platform 411 for guiding the trailer. The second wheel brake mechanism 418 has the same structure as the first wheel brake mechanism 127. Figure 6-Figure 8 .

[0069] Reference Figure 12-14 The fixing mechanism 44 includes a connecting plate 441, a locking member 442 and a positioning member 443. The connecting plate 441 is fixedly connected to the support frame 42. A hole that is compatible with the lifting platform 41 is opened in the center of the connecting plate 441. The connecting plate 441 is provided with a third trailer moving guide rail 444 for guiding the trailer. The locking member 442 and the positioning member 443 are fixed on the support frame 42. The locking member 442 is compatible with the locking switch 416, and the positioning member 443 is compatible with the supporting auxiliary beam 415. When the lifting platform 41 reaches the preset storage unit 21, it is positioned by the supporting auxiliary beam 415 and the positioning member 443, and the lifting platform 41 is fixed to the fixing mechanism 44 by the locking switch 416.

[0070] The dispatching system 4 in this embodiment has two main functions. One is to complete the dispatching between two storage units 21 when a certain lifting device 3 fails. The other is to assist the lifting device 3 of each storage unit 21 to work during the peak period of parking and retrieval. The lifting platform 41 in the dispatching system 4 is vertically lifted and lowered along the support frame 42 by the lifting platform driving mechanism 43. The lifting platform 41 is connected to each storage unit 21 through the second trailer moving guide rail 417 and the third trailer moving guide rail 444. Therefore, the lifting platform 41 of the present invention can dispatch vehicles in all parking spaces 212 of this parking garage.

[0071] The working principle of the dispatching system 4 is as follows: for ease of understanding and description, taking the dispatching from a storage unit 21 on the tenth floor to the storage unit 21 on the second floor as an example, the lifting platform driving mechanism 43 is started to lift the lifting platform 41 to the tenth floor, at this time, the supporting auxiliary beam 415 and the positioning member 443 are positioned, and the locking switches 416 at the lower ends of the supporting main beam 414 start to act, and the lifting platform 41 is fixed to the fixing mechanism 44 through the locking switches 416; the lifting platform 41 is flush with the moving channel 213 on the tenth floor, and the second trailer moving guide rail 417 and the third trailer moving guide rail 444 are also aligned and connected. At this time, the second rotating platform 412 on the lifting platform 41 rotates to the storage unit 21 to be picked up, and the corresponding mobile platform 214 of the storage unit 21 carries the vehicle to be picked up to the entrance of the second rotating platform 412, and the second trailer 216 on the mobile platform 214 drags the vehicle to the second rotating platform 412, and the second trailer 216 returns to the mobile platform Platform 214; the locking switches 416 at the lower ends of the supporting main beam 414 are unlocked, and the lifting platform driving mechanism 43 lowers the lifting platform 41 to the storage unit 21 on the second floor. At this time, the supporting auxiliary beam 415 and the positioning member 443 are positioned, and the locking switches 416 at the lower ends of the supporting main beam 414 start to act, and the lifting platform 41 is fixed to the fixing mechanism 44 through the locking switches 416; the lifting platform 41 is flush with the moving channel 213 on the second floor, and the second trailer moving guide rail 417 and the third trailer moving guide rail 444 are also aligned and connected. At this time, the second rotating platform 412 on the lifting platform 41 rotates to the storage unit 21 to be visited on the second floor, and the corresponding mobile platform 214 of the storage unit 21 runs to the entrance of the second rotating platform 412, and the second trailer 216 on the mobile platform 214 tows the vehicle onto the mobile platform 214, and the mobile platform 214 moves to the designated parking space 212 or the lifting device 3, and the scheduling system operation is completed.

[0072] Example 3

[0073] The difference between this embodiment and embodiment 2 is that, referring to Figure 15 and Figure 16 , also includes two storage layers 2 for storing large vehicles, including eight large vehicle storage units in total. The large vehicle storage units are arranged on the lower floors. There are also two storage layers 2 for charging new energy vehicles, including eight new energy vehicle storage units; each column where the large vehicle storage units are located is provided with a large vehicle lifting device 5, and the entry and exit layer 1 is provided with a large vehicle entry and exit lane 15, and the large vehicle entry and exit lane 15 is directly connected to the large vehicle lifting device 5; the new energy vehicle storage unit is provided with a charging pile.

[0074] The large vehicle storage unit of this embodiment is primarily used to store large vehicles (including large sedans, SUVs, and commercial MPVs). These vehicles enter a dedicated large vehicle lift 5 through a large vehicle access lane 15. The lift 5 is then raised to the designated large vehicle storage unit. A mobile platform 214 on a movable passage 213 moves to the location of the large vehicle lift 5. A second trailer 216 on the mobile platform 214 tows the vehicle inside the large vehicle lift 5 onto the mobile platform 214. The mobile platform 214 then moves to a designated parking space 212. The second trailer 216 tows the vehicle to the parking space 212 and then returns to the mobile platform 214. The third wheel brake mechanism 215 on the parking space 212 activates, securing the wheels, completing the storage process. The steps for retrieving the vehicle are the reverse of those for storage.

[0075] Since the large vehicle lifting device 5 is connected to each storage layer 2 of the annular three-dimensional parking garage of the present invention, in an emergency or during peak hours of parking and retrieval, vehicles in other storage layers 2 can be parked and retrieved through the large vehicle lifting device 5 and the large vehicle access lane 15.

[0076] Because vehicles in this circular multi-story parking garage are stored in a fixed location from the time they are parked until they are retrieved, unlike existing multi-story parking garages where vehicles are constantly shifting, this solution allows for a specific number of new energy vehicle storage units to be installed on a designated level. Charging stations of varying sizes are installed at the rear of parking spaces 212. New energy vehicles select the appropriate charging parking space based on their specific model, and the garage manager then completes the charging process. Other parking and retrieval methods are implemented similarly to conventional parking and retrieval.

[0077] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
