Description

Technical Field

[0001] This utility model belongs to the field of automated parking system technology, and in particular relates to a simple lifting automated parking system. Background Technology

[0002] Simple lift-type parking garages are popular in parking lots, especially underground ones, due to their simple structure and low cost. These garages typically consist of a steel frame that includes ground-level parking spaces and a second-level parking space. The second-level parking space has a lift platform. When parking on the ground level, vehicles need to be manually driven in or out of the parking space. When parking on the second level, the corresponding ground-level parking space must be empty before the lift platform descends to the ground level, and vehicles are then manually driven in or out. This requires a high level of driving skill.

[0003] Currently, the application of AGVs in automated parking systems is gradually being promoted. Existing AGV handling methods mainly rely on vehicle carriers and comb plates, which have two main drawbacks: first, AGVs need to carry the vehicle carrier or comb plate on their backs for vehicle storage and retrieval, requiring back-and-forth trips to retrieve or transport the vehicle carrier or comb plate, thus affecting vehicle storage and retrieval efficiency; second, AGVs need to enter the equipment interior and operate under the vehicle carrier or comb plate for transport. How to improve the vehicle storage and retrieval efficiency of simple lifting automated parking systems based on AGV structures has always been a technical challenge for those skilled in the art.

[0004] Therefore, in the field of automated parking system technology, there is still a need for research and improvement of simple lifting automated parking systems. 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 simple lifting three-dimensional parking garage to solve the technical problem of low vehicle storage and retrieval efficiency in a simple lifting three-dimensional parking garage based on AGV structure.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a simple lifting three-dimensional parking garage, including a steel structure frame, a transport aisle located on the ground floor within the steel structure frame, and ground-level parking spaces on both sides of the transport aisle. The ground floor of the steel structure frame has a first vehicle entrance and a second vehicle entrance and a third vehicle entrance, both of which are connected to the transport aisle. The second floor of the steel structure frame has several upper-level parking spaces, and each upper-level parking space is equipped with a lifting vehicle platform driven by a lifting power device. Front wheels for carrying vehicles are fixedly installed in each ground-level parking space. The vehicle platform includes a front wheel bracket and a rear wheel bracket. The lifting platform has a front wheel protrusion and a rear wheel protrusion to support the vehicle. The bottom surface of the front wheel protrusion has a front receiving cavity to accommodate the front wheel bracket, and the bottom surface of the rear wheel protrusion has a rear receiving cavity to accommodate the rear wheel bracket. The ground level of the steel structure frame has a first AGV trolley and a second AGV trolley corresponding to the first and second vehicle entrances / exits. Both the first and second AGV trolleys are equipped with slide rails. Wheel clamping devices for picking up and placing vehicles are slidably installed on the slide rails. The upper surface of the lifting platform has a docking rail adapted to the slide rails.

[0007] As an improvement, the end of the slide rail is provided with an inclined transition section, and correspondingly, the end of the docking rail is provided with an inclined docking section.

[0008] As a further improvement, the second floor of the steel structure frame is also provided with several upper-level parking spaces corresponding to the location of the transport aisle.

[0009] After adopting the above technical solution, the beneficial effects of this utility model are:

[0010] (1) When the system receives a vehicle storage or retrieval instruction, the AGV trolley and the simple lifting three-dimensional parking garage operate simultaneously, which improves the efficiency of vehicle storage and retrieval. Taking the storage of a vehicle in a two-story parking space as an example, the first AGV trolley, combined with the wheel clamping transporter, is responsible for transporting the vehicle from the entrance / exit to the parking space to be stored. At the same time, the second AGV trolley, combined with the wheel clamping transporter, moves the vehicle from the ground floor parking space corresponding to the parking space to be stored on the second floor and lowers the lifting vehicle platform of the parking space to the ground floor. Then, the AGV transports the vehicle onto the lifting vehicle platform, the lifting vehicle platform is raised to the second-story parking space, and after the first AGV trolley exits, the second AGV trolley puts the vehicle back in the original ground floor parking space, completing the vehicle storage.

[0011] (2) The lifting vehicle platform of this utility model is provided with a docking rail that is compatible with the slide rail, so that the wheel clamping transporter can reciprocate between the AGV trolley and the lifting vehicle platform, directly realizing the storage and retrieval of vehicles without having to repeatedly store and retrieve the vehicle platform, thereby greatly improving the vehicle storage and retrieval efficiency.

[0012] (3) Since the end of the slide rail is provided with an inclined transition part and the end of the docking rail is provided with an inclined docking part, the jig wheel transporter avoids the jerking sensation when crossing the gap between the slide rail and the docking rail, thus ensuring the smooth operation of the jig wheel transporter.

[0013] (4) Since the second floor of the steel structure frame also has several upper parking spaces corresponding to the transport lane, the number of cars that can be stored on the second floor is increased, thereby increasing the land utilization rate of the simple lifting three-dimensional garage.

[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The terms used in this specification, such as "front," "back," "left," "right," "inner," "outer," and "middle," are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.

[0027] A simple lifting-type parking garage, such as Figure 1 and Figure 2 As shown, the structure includes a steel frame 1, within which a transport aisle 2 located on the ground floor is provided. Ground-level parking spaces are located on both sides of the transport aisle 2. The ground floor of the steel frame 1 has a first vehicle entrance / exit 3 and a second vehicle entrance / exit 4, both connected to the transport aisle 2. The second floor of the steel frame 1 has several upper-level parking spaces, each equipped with a lifting platform 8 driven by a lifting power device. The lifting power device is typically a steel wire rope or chain structure driven by a geared motor; this structure is a common technique used by those skilled in the art and will not be described in detail here. Front wheel brackets 13 and rear wheel brackets 12 for carrying vehicles are fixedly installed within the ground-level parking spaces. Figure 5 and Figure 6As shown, the lifting platform 8 is provided with a front wheel protrusion 11 and a rear wheel protrusion 10 for carrying vehicles. The bottom surface of the front wheel protrusion 11 is provided with a front receiving cavity 802 for accommodating the front wheel bracket 13, and the bottom surface of the rear wheel protrusion 10 is provided with a rear receiving cavity 801 for accommodating the rear wheel bracket 12. When the lifting platform 8 is lowered, the front wheel bracket 13 and the rear wheel bracket 12 are covered by the front receiving cavity 802 and the rear receiving cavity 801 respectively, so that the bottom surface of the lifting platform 8 can be lowered to the ground. The ground layer of the steel structure frame 1 is provided with a first AGV trolley 5 and a second AGV trolley corresponding to the first vehicle entrance / exit 3 and the second vehicle entrance / exit 4, as shown. Figure 3 As shown, both the first AGV trolley 5 and the second AGV trolley are equipped with slide rails 6, and wheel clamping transporters 7 for picking up and placing vehicles are slidably installed on the slide rails 6. Figure 4 As shown, the wheel clamping transporter 7 is a common mechanism for those skilled in the art. For example, a wheel clamping transporter disclosed in Chinese invention patent CN111622563A and a wheel clamping transporter disclosed in Chinese utility model patent CN217461659U are examples. Their structures and functions are common technical means, which can be referenced and used by those skilled in the art, and will not be described in detail here. The upper surface of the lifting platform 8 is provided with a docking rail 9 that is adapted to the slide rail 6. The end of the slide rail 6 is provided with an inclined transition part 601. Correspondingly, the end of the docking rail 9 is provided with an inclined docking part 901. The inclined transition part 601 and the inclined docking part 901 are set at an internal offset angle to each other. The specific angle is preferably 45 degrees. By changing the straight gap at the end face to an inclined gap, the roller can always contact the slide rail 6 or the docking rail 9 when passing through, avoiding the jerking sensation when the wheel clamping transporter 7 crosses the gap between the slide rail 6 and the docking rail 9, and ensuring the smooth operation of the wheel clamping transporter 7.

[0028] This utility model's wheel-clamping transporter 7 can reciprocate between the AGV trolley and the lifting vehicle platform 8, directly realizing vehicle storage and retrieval without having to repeatedly access the vehicle platform, greatly improving vehicle storage and retrieval efficiency. Furthermore, this structure is particularly suitable for underground garage renovations, as personnel do not need to enter the underground garage; the AGV trolley is responsible for transporting vehicles to the entrance and exit. In addition, in the event of a fire or flood in the underground garage, when manual retrieval of vehicles is impossible, the AGV trolley and wheel-clamping transporter 7 can retrieve the vehicles and deliver them to the vehicle entrance / exit or a designated area, reducing vehicle loss.

[0029] When parking, the vehicle should enter the vehicle entrance / exit, such as... Figure 7As shown, if the parking space is located on the ground floor, the first AGV trolley 5 or the second AGV trolley moves to the corresponding vehicle entrance / exit position. The wheel clamping transporter 7 enters the vehicle entrance / exit and lifts the vehicle to be stored before returning to the corresponding AGV trolley. The AGV trolley moves to the parking space on the ground floor, enters the position between the two front wheel brackets 13 and the two rear wheel brackets 12 of that parking space, and then places the vehicle to be stored on the front wheel brackets 13 and the rear wheel brackets 12. The AGV trolley then drives away, and the parking is completed. Figure 8 As shown, if the parking space to be stored is located on the second floor, the first AGV trolley 5, combined with the wheel-clamping transporter 7, is responsible for transporting the vehicle from the entrance / exit to the parking space. Simultaneously, the second AGV trolley, combined with the wheel-clamping transporter 7, removes the vehicle from the ground-level parking space corresponding to the parking space on the second floor, lowering the lifting platform 8 of the parking space to the ground level. Then, the AGV transports the vehicle onto the lifting platform 8, which rises to the second-floor parking space. After the first AGV trolley 5 withdraws, the second AGV trolley returns the vehicle from the original ground-level parking space, completing the parking process. The key points here are: first, the AGV transport and the lowering of the lifting platform 8 to the ground level are performed simultaneously, significantly improving storage and retrieval efficiency; second, the AGV does not need to retrieve the empty lifting platform 8 to the entrance / exit, reducing the platform exchange process. The retrieval process is the reverse of the storage process and will not be elaborated further here.

[0030] The second floor of the steel frame 1 also has several upper parking spaces corresponding to the transport aisle 2. When vehicles are stored or retrieved in these parking spaces, the corresponding lifting platform 8 needs to be lowered to the ground. The ground floor has transport space for the first AGV trolley 5 and the second AGV trolley. This structure increases the number of vehicles that can be stored in the second-floor parking spaces, thereby increasing the land utilization rate of the simple lifting multi-level parking garage.

[0031] When storing or retrieving vehicles in the second-level parking spaces above the transport lane 2, the second AGV trolley, in conjunction with the wheel clamping transporter 7, first moves the vehicles from the ground-level parking spaces directly in front of or behind the parking spaces to be stored on the second level. The first AGV trolley 5 then carries the vehicles to the ground-level parking spaces directly in front of or behind the parking spaces to be stored. The lifting platform 8 of the parking space to be stored is then lowered to the ground level, and the first AGV trolley 5 transports the vehicles onto the lifting platform 8. The lifting platform 8 is then raised to the second-level parking space. After the first AGV trolley 5 withdraws, the second AGV trolley returns the vehicles from the original ground-level parking spaces, completing the storage process.

[0032] 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.
