Description

Technical Field

[0001] The utility model relates to a garage for parking multiple cars, in particular to a garage with mechanical equipment for moving vehicles, and specifically to a lifting turntable for a stereo garage and the stereo garage. Background Art

[0002] With the acceleration of urbanization, the number of motor vehicles has increased dramatically. This is especially true in older residential communities, where parking spaces are severely insufficient due to historical planning limitations. This has led to increasingly prominent parking difficulties and chaotic parking. To effectively address this issue, multi-story parking garages, as a space-efficient parking solution, have become a key component of older residential community renovations.

[0003] When installing a multi-story parking garage in a renovation of an older residential complex, key considerations include rational space utilization, cost control, and the impact on residents' lives. R&D teams typically design various types of multi-story parking garage systems, such as vertical circulation, lifting and lateral movement, and horizontal movement, to accommodate the spatial conditions of different communities.

[0004] Under cost constraints, the R&D team will optimize the design, use cost-effective materials and technologies, and simplify the structure to reduce construction costs. In addition, the design of the multi-story parking garage will also take into account the convenience and safety of operation, ensuring that residents can quickly and safely store and retrieve their vehicles.

[0005] Patent application CN118498806A discloses a multi-story parking garage that cleverly utilizes a frame structure centered around supporting columns. These columns are fixed structures, preventing translation or rotation, to stabilize the support frame and accommodate vehicle loads. Furthermore, the vehicle-mounted platform tracks, constructed around these supporting columns, achieve more stable operation, reducing the impact of dynamic loads on the garage, thereby lowering the overall structural strength requirements. This offers several benefits: a simplified support structure; support for high-rise garages with five or more floors; and, through the rational arrangement of support and rotational structures, significantly reducing the space required for garage operation (including escape space), making it suitable for installation in areas with narrow aisles or parking spaces.

[0006] Among them, the vehicle-mounted platform needs to be transported via a lifting turntable, which places high demands on the structure of the lifting turntable. On the one hand, the lifting turntable must be structurally strong and stable to support the smooth and long-term stable operation of the turntable. On the other hand, the lifting turntable must be as compact and lightweight as possible to reduce its own load and minimize interference with adjacent support, auxiliary, and drive structures to meet the overall compact design requirements of the multi-story parking garage. Therefore, there is a need to provide a complete solution that meets the above technical requirements and design intent. Utility Model Content

[0007] To address the shortcomings of the prior art, this utility model provides a lifting turntable for a multi-story parking garage. The main structure, constructed of welded steel, ensures structural stability during rotation, lifting, and other operations involving a vehicle-mounted platform. Furthermore, the turntable can withstand both dynamic and static loads, ensuring strength even under fluctuating load conditions. Finally, the design is rational, fully utilizing space, and achieving a compact design. This design at least addresses or alleviates one or more technical issues in the prior art, or at least provides a beneficial alternative.

[0008] The technical solution adopted by the present invention to solve the above technical problems is:

[0009] A lifting turntable for a stereo garage, comprising

[0010] front panel;

[0011] a pair of side panels connected to the edges of both sides of the front panel, wherein the pair of side panels are perpendicular to the front panel;

[0012] a motor bracket connected to the front panel at the front of the front panel; and connected to the side panel at the outer side of the side panel;

[0013] a rotary drive motor mounted on the motor bracket;

[0014] a rotating shaft support assembly connected to the front panel in front of the front panel and located below the motor bracket;

[0015] a rotating shaft mounted on the rotating shaft support assembly;

[0016] A track seat connected to the rotating shaft;

[0017] The short track is installed on the track seat.

[0018] Through rational structural design, the lift turntable boasts sufficient load-bearing capacity within a relatively lightweight and compact design, enabling it to safely carry heavy vehicles. Structural stability and load-bearing capacity are crucial, especially during the lifting and rotation processes. Furthermore, the load capacity varies depending on the vehicle parked, with the ratio between unloaded and loaded often ranging from 1:4 to 1:8. Furthermore, the majority of the load borne by the lift turntable is dynamic, requiring sufficient strength in its welded structure.

[0019] This solution utilizes a combined front panel, side panels, and motor bracket design to create a stable frame structure. The front panel and side panels are vertically connected to enhance overall rigidity. The dual connection of the motor bracket to both the front panel and side panels ensures stable mounting of the drive motor and even force distribution, thereby increasing the structure's load-bearing capacity.

[0020] Structural stability is crucial for ensuring the safe operation of a multi-story parking garage, as ensuring stability can mitigate potential safety hazards. The connection between the rotating shaft support assembly and the front panel is located below the motor bracket. This layout effectively disperses the forces during rotation and enhances the stability of the shaft. The shaft is mounted within the rotating shaft support assembly, ensuring smooth rotation and reducing vibration and noise caused by structural instability.

[0021] In addition, in a multi-story parking garage with limited space, how to design a lifting turntable with a compact structure and small footprint is the key to improving space utilization.

[0022] The design of the vertical connection between the front panel and the side panels utilizes the three-dimensional space and reduces the floor space. The stability of the vertical structure also means that higher structural strength can be achieved within a limited space, reducing the need for additional support, thereby achieving a compact design. The multi-point connection between the motor bracket and the front panel and side panels not only ensures the stability of the motor, but also places the motor in a position without taking up additional space through reasonable layout. The motor bracket is located in front of the front panel and corresponds to the rotating shaft support assembly above and below. This design avoids the expansion of the lateral space and is conducive to a compact design. The rotating shaft support assembly is located below the motor bracket. This layout makes full use of the vertical space and avoids additional occupation in the horizontal direction. It helps to reduce the lateral size of the turntable and achieve a more compact structure.

[0023] These design elements work together to optimize space utilization while maintaining functionality and stability. The vertical structure and compact layout of the motor and support components combine to achieve compactness and efficiency, making it ideal for space-constrained parking garages. This not only improves garage space utilization, but also streamlines the parking and retrieval process, enhancing the user experience.

[0024] In summary, this solution, through the rational arrangement of the main steel structure, enhances the structural load-bearing capacity and stability, ensuring the safe operation of the lift turntable when carrying heavy vehicles. It also optimizes space utilization. The compact design reduces interference with the lift turntable and reduces the turning radius without adding additional space. This improves parking efficiency in the multi-story garage while reducing the floor space and the torque acting on dynamic loads. The stable structure and compact design also make vehicle lifting and rotation smoother, shortening parking time and improving user satisfaction.

[0025] In addition, the structural stability and compact design reduce the failure rate during operation and reduce maintenance and operating costs.

[0026] In a preferred embodiment, the motor bracket includes

[0027] A connecting bottom plate connected to the front panel at the front of the front panel;

[0028] a motor mounting plate welded to the connecting base plate, the rotary drive motor being mounted on the motor mounting plate;

[0029] A pair of connecting side plates, respectively welded to the side edges of the motor mounting plate and the outer sides of the pair of side plates;

[0030] A reinforcing rib welded between the connecting base plate and the motor mounting plate.

[0031] In the design of a lifting turntable, the motor bracket needs to bear the weight of the rotating drive motor and withstand vibration and torque during motor operation. The connection between the base plate and the front panel, as well as the welding of a pair of side panels, form a stable frame structure, significantly enhancing the rigidity of the motor bracket, effectively sharing the vibration and torque during motor operation, and ensuring the long-term stability and safety of the structure.

[0032] Efficient space utilization is also crucial. While ensuring structural stability, the spatial layout must be further optimized to achieve a compact design. The motor mounting plate allows the rotary drive motor to be compactly mounted on the motor bracket. Furthermore, the outer surfaces of the connecting side panels are welded to each other, ensuring a secure connection between the motor brackets without adding additional lateral space. This layout optimizes space utilization and achieves a compact structure.

[0033] The vibration and noise generated by motor operation can affect device stability and user experience. Effectively controlling vibration and reducing noise are key design considerations.

[0034] The reinforcing ribs are welded between the connecting base plate and the motor mounting plate, further enhancing the overall structural strength of the motor bracket, effectively dispersing the vibration during motor operation, reducing structural deformation and noise generation, and improving the stability and quietness of equipment operation.

[0035] By enhancing the stability and strength of the structure, optimizing the spatial layout, achieving structural compactness, and effectively controlling vibration and noise, it not only improves the operational stability and safety of the lifting turntable, but also optimizes the space utilization efficiency and user experience of the stereo parking garage.

[0036] In a preferred embodiment, the rotating shaft support assembly includes

[0037] A pair of support bases welded to the bottom and the front panel and to the front side of the front panel;

[0038] A main shaft rotating tube connected between the pair of support seats and sleeved on the outside of the rotating shaft;

[0039] Bearings installed at both ends of the spindle rotating tube form an interference fit with the shaft shoulder of the rotating shaft;

[0040] A pair of vertical plates are located between the spindle rotating tube and the front panel, and are welded to the pair of support seats and the front panel at the same time.

[0041] During the operation of the lifting turntable, the rotating shaft needs to withstand a large rotational torque. A pair of support seats are welded to the front side of the front panel to form a stable basic support; the main shaft rotation tube is sleeved on the outside of the rotating shaft, and the bearings at both ends form an interference fit with the shaft shoulder of the rotating shaft, ensuring stable support and smooth rotation of the rotating shaft during the rotation process, thereby improving the rotation accuracy and stability of the equipment operation.

[0042] The connection between the rotating shaft and the supporting assembly is reliable, and the bearing and the rotating shaft form an interference fit, which ensures a tight connection between the two, improves the reliability of the connection between the rotating shaft and the supporting assembly, and ensures the accuracy of the rotation process.

[0043] The design of a pair of vertical plates not only enhances the stability of the overall structure, but also optimizes the spatial layout through welding with the support base and the front panel, achieves structural compactness, and improves the space utilization efficiency of the stereo garage.

[0044] In addition, the rotating shaft support assembly is connected through multiple welding points (support base and front panel, vertical plate and support base and front panel) to form a stable frame structure, which significantly enhances the stability and strength of the assembly and provides a solid structural guarantee for the long-term operation of the equipment.

[0045] In a preferred embodiment, the rotating shaft support assembly further includes

[0046] A rotary flange connected to the support seat and located at both ends of the spindle rotary tube;

[0047] A bearing cover cooperates with the slewing flange, and the bearing is located between the slewing flange and the bearing cover.

[0048] In rotating shaft support assemblies, the protection and precise positioning of bearings ensure smooth rotation and extend the overall system life. The slewing flange, connected to the support seat at each end of the spindle's slewing tube, provides mounting locations for the bearings and locally reinforces key support locations for reliable support, forming a typical bearing seat structure. Combined with the use of bearing caps, these not only protect the bearings and prevent direct interference from external factors, but also ensure precise bearing positioning, improving the smoothness and stability of the rotating shaft's rotation.

[0049] The combination of the bearing cover and the slewing flange forms an easy-to-disassemble structure, which facilitates the inspection and replacement of the bearing during maintenance and overhaul, reducing maintenance costs and improving maintenance efficiency.

[0050] In addition, the close fit between the slewing flange and the bearing cover forms a good seal, effectively preventing the entry of dust and moisture, protecting key parts such as internal bearings, and improving the reliability and service life of the equipment.

[0051] The coordinated use of the slewing flange and bearing cap not only effectively protects the bearing, ensures its precise positioning, and improves the smoothness and stability of the rotating shaft's rotation; it also enhances the convenience of maintenance and overhaul, reducing maintenance costs. At the same time, it enhances the equipment's sealing, dustproof, and waterproof properties, significantly improving the reliability and service life of the rotating shaft support assembly, providing a safer, more efficient, and easier-to-maintain solution for the lift turntable in a multi-story parking garage. Furthermore, the use of a welded structure to form the rotating support for the rotating shaft can also reduce production costs. Compared to cast structures, the material of the welded plate is more stable and has superior performance. After welding, stress removal through ultrasonic vibration or heat treatment, followed by machining, can also ensure machining accuracy.

[0052] In a preferred embodiment, the track base comprises

[0053] Track seat plate;

[0054] a pair of connecting plates welded to the rear side surfaces of the track seat plates;

[0055] A pair of connecting members are provided at the upper end and the lower end of the connecting plate, wherein the pair of connecting members are connected to the rotating shaft;

[0056] The short rail is installed on the front side of the rail seat plate.

[0057] During the operation of the lifting turntable, the track seat needs to bear the load and the forces generated by the movement, so the structural stability and strength of the track seat must be ensured to support the short track and the load. The welded design of the track seat upright plate and a pair of connecting plates forms a stable support structure, ensuring the stability and strength of the track seat when bearing the load. The short track is installed on the front side of the track seat upright plate and connected to the rotating shaft through a pair of connecting parts, ensuring the precise installation and stable operation of the short track, and improving the smoothness and positioning accuracy of the lifting turntable. The design of the track seat upright plate and the connecting plate, as well as the front side installation of the short track, achieves efficient space utilization, reduces the space occupied by the track seat, and improves the compactness of the entire lifting turntable. At the same time, it not only simplifies the connection with the rotating shaft, but also facilitates disassembly and inspection during installation and maintenance, reducing maintenance costs and improving maintenance efficiency.

[0058] In a preferred embodiment, it also includes

[0059] Four hook-shaped reinforcing ribs are respectively located at the upper and lower ends of the connecting edges of the front panel and the two sides of the side panels, and the inner sides of the hook-shaped reinforcing ribs are respectively in contact with the front side of the front side and the outer side of the side panel.

[0060] In stereo garage equipment, the strength and stability of structural components must be ensured when bearing loads and forces generated by movement. Hook-shaped reinforcement ribs are located at the upper and lower ends of the connection edge between the front panel and the side panels. The inner side of the hook-shaped structure fits the front of the front side and the outer side of the side panel, effectively enhancing the structural strength of the connection area and significantly improving the stability and load-bearing capacity of the equipment. The fit of the hook-shaped reinforcement ribs to the panel and side panels not only strengthens the connection between the components, but also improves the sealing of the structural parts due to the tight fit, effectively preventing the intrusion of dust and moisture, and improving the dust and water resistance of the equipment. The design of the hook-shaped reinforcement ribs does not take up additional space, but cleverly utilizes the connection edge of the existing structure, achieving structural optimization and efficient use of space, improving the overall performance and space utilization of the equipment.

[0061] In a preferred embodiment, the rotary drive motor is vertically arranged, and a central axis is concentric with the rotating shaft.

[0062] The vertically positioned rotary drive motor, with the central axis concentric with the rotating shaft, enables direct power transmission, avoiding power loss due to angular deviation, ensuring efficient and stable power transmission, and improving equipment operating efficiency. The vertical motor layout not only saves horizontal space but also forms a compact structure with the rotating shaft, achieving efficient space utilization and improving the overall compactness of the equipment, making it particularly suitable for space-constrained parking garages. The concentric arrangement of the motor and the rotating shaft reduces vibration and noise during operation, improving operational smoothness, ensuring safe operation, and extending the equipment's service life.

[0063] In a preferred embodiment, the short track includes an upper track and a lower track, and the upper track is parallel to the lower track.

[0064] The short track is set as a parallel upper and lower double layer, which can disperse the load, ensure the stable transmission of vertical and horizontal forces, improve stability, and especially reduce the lateral overturning force applied to the turntable caused by the load. By dispersing the load, the action area of ​​the overall rotating load is expanded to support the compact lifting turntable to stably carry the vehicle loading platform and parked vehicles, and reduce the impact and noise during operation and start-up and operation.

[0065] In another aspect, the utility model also provides a three-dimensional parking garage, comprising

[0066] A lifting column, wherein the lifting column includes a lifting track;

[0067] As described above, the lifting turntable for a stereo garage further comprises a walking unit cooperating with the lifting track, and the walking unit is mounted on the side panel;

[0068] The lifting drive unit provided on the lifting column is connected to the lifting turntable and can drive the lifting turntable to move up and down along the lifting column.

[0069] The transportation of the vehicle loading platform in the stereo garage is mainly achieved through three parts: the lifting column, the lifting turntable (including the walking unit) and the lifting drive unit. The lifting turntable includes a walking unit that cooperates with the lifting track and is installed on the side panel, while the lifting drive unit is set on the lifting column and connected to the lifting turntable.

[0070] The lifting efficiency of a stereo garage directly impacts vehicle access speed, necessitating efficient and stable operation of the lift turntable. The coordinated design of the lifting travel unit and the lifting rails ensures smooth operation of the lift turntable during the lifting process, reducing vibration and improving operational efficiency and stability. The coordinated design of the lifting columns and lift turntable, through the precise coordination of the travel unit and rails, achieves efficient utilization of vertical space, reduces unnecessary space occupation, and increases the overall capacity of the garage.

[0071] In a preferred embodiment, part of the walking unit is arranged on the inner side of the side plate.

[0072] The design of arranging part of the traveling unit on the inner side of the side panel can effectively reduce the space occupied by the traveling unit inside the stereo garage and optimize the structural layout of the lifting turntable. This layout makes the equipment more compact as a whole and improves the efficiency of space utilization. The inner arrangement of the traveling unit reduces the impact of external environmental factors (such as wind, debris, etc.) on the traveling unit and improves the stability of operation. At the same time, the inner layout reduces the risk of the traveling unit being exposed to the outside and increases safety. By arranging part of the traveling unit on the inner side of the side panel, the traveling unit can be easily accessed when maintenance or inspection is required by designing an openable structure of the side panel or reserving maintenance space, thereby improving the convenience and accessibility of maintenance and reducing maintenance costs and time.

[0081] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0082] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0084] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0087] like Figure 1 As shown in one embodiment, a lifting turntable for a stereo garage is shown, combined with Figure 2 The lifting turntable includes a turntable body 100 mainly formed by a welded steel structure, including a front panel 110; a pair of side panels 120 connected to the edges on both sides of the front panel 110, and the pair of side panels 120 are perpendicular to the front panel 110; the front panel and a pair of side panels constitute an open box structure, which can have sufficient installation space, have sufficient strength, and meet the requirements of compactness. The main executive structures of the lifting turntable are all installed around the box structure. The appropriate plate thickness can be selected according to the load-bearing requirements. In the working state, the load of the lifting state will be concentrated on this box structure, and only the plate thickness needs to be increased. The increase in its own load is negligible, but it can provide sufficient supporting strength. In addition, the connection between the front panel and the side panels adopts a double-sided full weld welding method to ensure a reliable connection.

[0088] The motor bracket 130 is connected to the front panel 110 on the front of the front panel 100 and to the side panels 120 on the outer side of the side panels 120. The rotary drive motor 200 is mounted on the motor bracket 130. The motor bracket supports the rotary drive motor and is connected to the front panel and side panels, reinforcing the outer side of the box-type structure. It also has sufficient strength to support the motor. When the rotary drive motor is in operation, it generates impact and vibration. The motor bracket and the box-type structure work together to absorb and resist these impacts and vibrations, ensuring the overall stability of the lift turntable.

[0089] In addition, combined Figure 3 , there is also a rotating shaft support assembly 300, which is connected to the front panel 110 in front of the front panel 110 and is located below the motor bracket 130; a rotating shaft 400 is installed on the rotating shaft support assembly 300; the rotating shaft can rotate around a fixed axis under the support of the rotating shaft support assembly and is driven by a rotating drive motor. The rotating shaft support assembly can be regarded as a pair of bearing seats, supporting the two ends of the rotating shaft. The length of the rotating shaft and the span of the supporting position correspond to the length of the front panel. The load borne and transmitted by the rotating shaft also acts on the front panel, so that the upper part of the front panel receives a forward pulling force and the lower part receives a backward thrust. The box-type structure can properly support and resist this complex load, especially the dynamic load generated when the rotating shaft rotates.

[0090] The track base 500 is connected to the rotating shaft 400; the short track 600 is installed on the track base 500. Through the connection between the track base and the rotating shaft, the rotary drive motor can drive the track to rotate to achieve tracks of different angles. Combined with the multi-story parking garage structure disclosed in CN118498806A in the background technology (this application will quote this patent document in its entirety to further clarify the application scenarios of the solution described in this application and the technical problems solved by the solution), it can drive the short track to connect with the track beam to form an extension of the track beam, allowing the vehicle loading platform to move from the track beam to the short track. The rotating shaft then drives the track base to rotate, allowing the vehicle loading platform to rotate around the supporting column. It can be seen that this process will generate dynamic loads, which will eventually act on the box-type structure composed of the front panel and side panels, and be reliably supported and stably resisted to avoid deformation and noise, thereby ensuring the smooth operation of the multi-story parking garage.

[0091] Combine Figure 4 and Figure 5 As a supporting structure for the rotation drive motor, the motor bracket 130 includes a connecting base plate 1301 connected to the front panel at the front of the front panel; a motor mounting plate welded to the connecting base plate 1301, and the rotation drive motor is mounted on the motor mounting plate 1301; Figure 7The motor mounting plate can be machined with mounting notches to match the rotary drive motor and ensure precise positioning. A pair of connecting side plates 1303 are welded to the sides of the motor mounting plate 1302 and the outer surfaces of the pair of side plates 1301, respectively; and reinforcing ribs 1304 are welded between the connecting base plate 1301 and the motor mounting plate 1302.

[0092] The rotary drive motor is installed on the motor mounting plate, and then the vibration and impact during the operation of the motor will be transmitted to the motor mounting plate, and the motor mounting plate will then transmit it to the entire motor bracket. The various parts of the motor are directly welded to each other to form a whole, which can reliably transmit the load and has sufficient rigidity and strength to ensure the stable operation of the motor.

[0093] Combine Figures 1 to 3 The rotating shaft support assembly 300 includes a pair of support bases 310 welded to the front side of the front panel. A spindle rotation tube 320 is connected between the support bases 310 and fits over the outer surface of the rotating shaft 400. Bearing mounting grooves are machined at both ends of the spindle rotation tube to mate with the outer races of the bearings. Bearings (not shown) mounted at both ends of the spindle rotation tube form an interference fit with the shoulders of the rotating shaft 400, forming the supporting structure for the rotating shaft.

[0094] Furthermore, a pair of vertical plates 330 are located between the spindle rotating tube 320 and the front panel, and are welded to the pair of support bases 310 and the front panel. Thus, the vertical plates form an integral framework for the spindle's support structure, ensuring stable, smooth, noiseless, and heavy-load-resistant operation.

[0095] The rotating shaft support assembly also includes rotating flanges 340 connected to the support base 310 and located at both ends of the spindle rotating tube 320; bearing caps 350 cooperate with the rotating flanges 340, with the bearings located between the rotating flanges 340 and the bearing caps 350. The bearings are load-transmitting components and a core load-bearing structure. The rotating flanges reinforce the bearing positions of the spindle rotating tube and provide mounting space for the bearing caps. Through welding, they form a sturdy, integrated bearing seat structure, providing reliable support for the rotating shaft and protecting the stable operation of the bearings.

[0096] Combine Figure 3 The track base 500 includes a track base plate 510 and a pair of connecting plates 520 welded to the rear side of the track base plate 510. As shown, the connecting plates are door-shaped, which reduces their own load, minimizes interference during operation, and reduces the difficulty of designing interference elimination. A pair of connecting members 530 are located at the upper and lower ends of the connecting plate 520 and are connected to the rotating shaft 400. The short track 600 is mounted on the front side of the track base plate 510. This allows the rotating shaft to drive the track base to rotate.

[0097] In addition, reference Figure 2 The lift turntable also includes four hook-shaped reinforcement ribs 140 located at the upper and lower ends of the connecting edges of the front panel 110 and the side panels 120. The inner surfaces of the hook-shaped reinforcement ribs 140 respectively contact the front surface of the front side panel 110 and the outer surfaces of the side panels 120. Although lightweight, the hook-shaped reinforcement ribs significantly enhance the strength and rigidity of the turntable's main structure without adding excessive additional load.

[0098] like Figure 1 The rotary drive motor 200 is vertically mounted, with its central axis concentric with the rotating shaft. This minimizes the transmission path and improves transmission efficiency. The use of a vertical motor in conjunction with a coaxial speed control device, such as a pinwheel cycloid reducer, creates a nearly centrally symmetrical structure. This reduces the load torque during turntable rotation, resulting in smoother operation and less interference during rotation.

[0099] like Figure 3 The short track 600 includes an upper track 610 and a lower track 620, which are parallel to each other. The upper and lower tracks simultaneously support the vehicle loading platform, distributing the load acting on the lifting turntable, reducing the strength requirements for the turntable as a whole and the rotating shaft, and ensuring smoother operation and reducing noise.

[0100] Combine Figure 6 , depicts a stereo garage, including a lifting column 0100, the lifting column 0100 includes a lifting track; as described above for the lifting turntable of the stereo garage, combined with Figure 1 and Figure 3 The lifting turntable used in the stereo garage also includes a walking unit 700 that cooperates with the lifting track, and the walking unit 700 is installed on the side panel; the lifting drive unit 0200 arranged on the lifting column 0100 is connected to the lifting turntable and can drive the lifting turntable to move up and down along the lifting column 0100.

[0101] Among them, some walking units are arranged on the inner side of the side panels.
