Description

Technical Field

[0001] The utility model relates to a garage for parking multiple vehicles, especially a garage with mechanical equipment for moving vehicles, and specifically to a three-dimensional garage with a lifting structure. Background Art

[0002] The lifting action in a three-dimensional garage is a key link for vehicle access. It involves the motion control of various parking space units inside the garage. The design and implementation of the lifting action are crucial for ensuring the normal operation of the three-dimensional garage, improving the access efficiency, and guaranteeing the safety of vehicles and users.

[0003] A lifting type three-dimensional garage usually adopts a steel structure frame, in which vehicle body units with lifting and traversing functions are distributed. Through the instructions of the control system, the car carrier plate can perform lifting and traversing actions and operate according to the preset control logic to complete the vehicle access process.

[0004] Among them, the accuracy of the lifting action is crucial for the safety and efficiency of the three-dimensional garage. Precise control of the lifting action can ensure that the car carrier plate smoothly rises to the designated floor, avoiding vehicle damage or personal injury caused by uneven lifting. In addition, precise lifting actions contribute to improving the operation efficiency of the garage, reducing the noise generated during the operation of the equipment due to inaccurate lifting positioning, thereby enhancing the user experience.

[0005] At the same time, reliable positioning for the transition from lifting to traversing position is very crucial for the vehicle access operation of the three-dimensional garage. Only when the car carrier plate is accurately positioned at the traversing position can it ensure that vehicles can enter and exit the garage smoothly, avoiding vehicle collisions or jams caused by inaccurate positioning. A reliable positioning system can also reduce the maintenance costs caused by operation errors and extend the service life of the garage.

[0006] When designing and implementing the positioning system for the transition from lifting to traversing position, sensors such as laser rangefinders and encoders are usually used to detect the position of the car carrier plate, and a control system such as a PLC is used to precisely control the movement of the car carrier plate to achieve positioning.

[0007] However, relying solely on instrument positioning and system control, there are certain deficiencies in the stability and safety of the equipment. Therefore, there is such a need in the field of three-dimensional garages to achieve precise positioning of the lifting action through a sensitive and reliable mechanical positioning structure. Summary of the Utility Model

[0008] The present utility model aims to make up for the deficiencies of the prior art and provides a three-dimensional garage with a lifting structure, which solves the problems of inaccurate positioning and excessive descent of the lifting platform. The combined use of the first limit block and the first telescopic unit provides a reliable stopping point for the lifting platform, ensuring that it stops at the correct height position, thereby avoiding noise generation, equipment damage, and safety hazards. It can at least solve or alleviate one or more technical problems in the prior art, or at least provide a beneficial alternative.

[0009] The technical solution adopted by the present utility model to solve the above technical problems is as follows:

[0010] A three-dimensional garage with a lifting structure, comprising

[0011] A fixed support column, comprising

[0012] A first limit block;

[0013] A lifting drive unit;

[0014] A lifting platform that can be driven by the lifting drive unit to lift along the support column, comprising

[0015] A positioning and blocking assembly, the positioning and blocking assembly comprising a positioning and blocking seat and a first telescopic unit. When the first telescopic unit is in the extended state, a part of it extends out of the positioning and blocking seat and can cooperate with the limit block to prevent the downward trend of the lifting platform.

[0016] Through the above solution, by setting the positioning and blocking assembly and the first telescopic unit, accurate positioning can be achieved when the lifting platform reaches the specified position, ensuring that the vehicle can be parked in the parking space accurately and improving the use efficiency of the garage. The cooperation between the first telescopic unit and the limit block can effectively prevent the accidental descent of the lifting platform. Even when the lifting drive unit fails, the stability of the lifting platform can be ensured, thereby improving the safety of the garage. Through the coordinated work of the precise positioning and blocking assembly and the telescopic unit, high-precision control of the lifting platform can be achieved, which not only improves the operation efficiency of the garage but also reduces the risk of vehicle damage caused by inaccurate control. It fully reflects the reliability and superiority of the mechanical structure in automated equipment such as three-dimensional garages that require high safety and reliability.

[0017] In a preferred embodiment, the first telescopic unit cooperates with the limit block in a manner of fitting and pressing.

[0018] By means of the fitting and pressing cooperation between the first telescopic unit and the limit block, the technical problems of the positioning accuracy and stability of the lifting platform are solved. During the ascending or descending process of the lifting platform, the extended part of the first telescopic unit can be in close contact with the limit block to form a physical resistance, preventing the lifting platform from exceeding the predetermined position, so as to ensure that the lifting platform stays at the correct layer, and avoiding vehicle damage or safety accidents caused by inaccurate positioning. By means of the fitting and pressing method, the position of the lifting platform can be controlled more precisely. Since the cooperation between the first telescopic unit and the limit block does not require a complex mechanical structure, the maintenance difficulty and operation complexity can be reduced, and the reliability and durability of the system can be improved.

[0019] In a preferred embodiment, the first telescopic unit is a cam, which has a first protrusion, and the first protrusion has a pressing surface that cooperates with the bearing surface of the first limit block; when the cam rotates to the first position, the first protrusion extends out of the positioning seat, and the pressing surface can be in close contact with the bearing surface; when the cam rotates to the second position, the first protrusion retracts into the positioning seat.

[0020] By introducing the cam mechanism as the first telescopic unit, the positioning and stability problems of the lifting platform of the stereoscopic garage are further optimized. The close contact between the first protrusion of the cam and the bearing surface of the limit block can achieve the precise stop of the lifting platform at a specific position, ensuring that the vehicle can be accurately parked in the designated parking space. The rotation position of the cam controls the extension and retraction of the first protrusion. This mechanical control method simplifies the requirements of the electrical control system, reduces the complexity and failure rate of the system. When the cam rotates to the first position, the first protrusion is in close cooperation with the limit block to form a stable support point, preventing the lifting platform from accidentally descending due to external force or system failure, and improving the stability and safety of the lifting platform.

[0021] In addition, by adjusting the design parameters of the cam, such as the height and shape of the protrusion, different positioning requirements and load conditions can be adapted, increasing the flexibility and adjustability of the system.

[0022] In a preferred embodiment, a support block is arranged in the positioning seat, and the cam has a second protrusion; when the cam rotates to the first position, the second protrusion contacts the support block and stops the rotation trend of the cam.

[0023] By the cooperation of the first protrusion of the cam with the limit block and the contact of the second protrusion with the support block, double positioning of the lifting platform at a specific position can be achieved. When the cam rotates to the first position, the second protrusion contacts the support block, forming an additional stopping force to prevent the cam from continuing to rotate due to external force or system failure, thereby avoiding accidental movement of the lifting platform and improving the stability and safety of the lifting platform. Through the cooperation of the support block and the second protrusion, the control system of the lifting platform can be simplified, reducing the dependence on external power sources or sensors and lowering the complexity and maintenance cost of the system.

[0024] Obviously, the mechanical cooperation mode of the cam and the support block has high durability and anti-interference ability, can work stably in harsh environments, and improves the reliability of the entire system.

[0025] In a preferred embodiment, it further includes a second limit block. The first limit block and the second limit block are respectively arranged on both sides of the support column, and the positioning gear assembly is located between the first limit block and the second limit block;

[0026] The positioning gear assembly further includes a second telescopic unit. When the second telescopic unit is in the extended state, the extended part can cooperate with the second limit block to prevent the downward trend of the lifting platform.

[0027] By adding the second limit block and the second telescopic unit, the positioning accuracy and stability of the lifting platform of the stereoscopic garage are further enhanced.

[0028] By respectively arranging the first limit block and the second limit block on both sides of the support column, bilateral limiting of the lifting platform can be achieved. By arranging limiting devices on both sides of the lifting platform, the external forces that the lifting platform may receive during the lifting process can be balanced, avoiding imbalance problems caused by excessive force on one side.

[0029] The cooperation of the second telescopic unit and the second limit block provides additional safety guarantees. Even if the limiting device on one side fails, the limiting device on the other side can still prevent the accidental descent of the lifting platform, improving the safety of the lifting platform.

[0030] In a preferred embodiment, the first telescopic unit and the second telescopic unit extend and contract synchronously.

[0031] Setting the same limiting mechanism on both sides can simplify the design of the control system, eliminating the need for complex algorithms to adjust the telescoping speed and timing on both sides, reducing the complexity of control, while also reducing the number and complexity of control components and lowering the maintenance cost. The limiting devices set on both sides of the lifting platform need to be precisely synchronized to ensure the consistency of the lifting platform's movement in the vertical direction. Synchronous extension and retraction can maintain the horizontal state of the lifting platform, balance the forces on the lifting platform, and ensure the vehicle is parked stably. The telescoping units with synchronous extension and retraction can provide more reliable safety protection. In case of an emergency, the limiting devices on both sides can act simultaneously to prevent the accidental descent of the lifting platform, enhancing the safety of the lifting platform.

[0032] In a preferred embodiment, both the first telescoping unit and the second telescoping unit are of cam construction; the positioning and blocking assembly further includes

[0033] a driving motor,

[0034] a transmission shaft connected to the output shaft of the driving motor, with the first telescoping unit or the second telescoping unit mounted on the transmission shaft,

[0035] a transmission gear mounted on the transmission shaft,

[0036] a transmission bearing seat for supporting the transmission shaft;

[0037] a driven shaft, with the second telescoping unit or the first telescoping unit mounted on the driven shaft,

[0038] a driven gear mounted on the driven shaft and meshing with the transmission gear,

[0039] a driven bearing seat for supporting the driven shaft.

[0040] Through the driving motor and the transmission system, it is ensured that the first telescoping unit and the second telescoping unit can extend and retract precisely synchronously; through mechanical transmission devices such as the transmission shaft, transmission gear, driven shaft, and driven gear, the power of the driving motor is effectively transmitted to the two telescoping units, achieving efficient and reliable power transmission; through the support of the transmission bearing seat and the driven bearing seat, the stable operation of the transmission shaft and the driven shaft is guaranteed, enhancing the stability and service life of the system; through the mechanical transmission method, the design of the electrical control system is simplified, the dependence on complex sensors and control algorithms is reduced, and the complexity and maintenance cost of the system are lowered.

[0041] In a preferred embodiment, the support column is an H-shaped steel structure, including a web and a pair of flange plates; the first limiting block and the second limiting block are respectively mounted on the pair of flange plates.

[0042] Due to its unique cross-sectional shape, the H-shaped steel structure has high strength and rigidity, can withstand large vertical and horizontal loads, and ensures the overall stability and safety of the lifting platform of the three-dimensional garage. By installing the first limit block and the second limit block on a pair of flange plates of the H-shaped steel respectively, the structural advantages of the flange plates can be fully utilized to provide a stable support for the limit blocks, ensuring that they can accurately limit and guide the movement of the lifting platform during the lifting process. In addition, the H-shaped steel is a widely used standardized structural material, which is easy to purchase and process, conducive to the modularization and standardization of the three-dimensional garage design, and reduces the production cost and construction difficulty. The support columns of the H-shaped steel structure and the limit blocks on its flange plates are convenient for inspection and maintenance. When the limit blocks or other components need to be replaced, they can be quickly disassembled and installed, reducing the downtime and improving the availability of the equipment.

[0043] In a preferred embodiment, the support column further includes a first walking track provided on the web and a second walking track provided on the flange.

[0044] The lifting platform has a first walking unit corresponding to the first walking track and a second walking unit corresponding to the second walking track.

[0045] By setting the walking tracks and walking units, a clear movement path and stable support are provided for the lifting platform, ensuring that the lifting platform maintains the correct position and direction during the vertical lifting process.

[0046] Setting two sets of walking tracks and walking units on the support column helps to balance the external forces that the lifting platform may receive during the lifting process. Especially when the lifting platform carries vehicles with different weight distributions, the walking units on both sides can work together to keep the lifting platform balanced. Such a design improves the overall stability of the lifting platform. Through the mechanical guiding and supporting mechanism, it can work stably in a harsh environment, improving the reliability of the entire system. Even during high-speed lifting or when encountering external disturbances, the lifting platform can still operate smoothly.

[0047] In a preferred embodiment, the top surface height of the first limit block and / or the second limit block is adjustable.

[0048] The adjustable top surface height of the first limit block and / or the second limit block solves the following technical problems:

[0049] Fixed-height limit blocks may need to be replaced due to wear or damage during long-term use, while adjustable limit blocks can be repaired by simple adjustment, reducing the maintenance cost and downtime. During the installation and commissioning process, the limit height of the limit blocks can also be adjusted through the adjustable structure, thereby reducing the overall installation accuracy requirements and facilitating frequent commissioning.

[0069] To clearly illustrate the technical features of this solution, the present utility model will be elaborated in detail below through specific embodiments in combination with the accompanying drawings.

[0070] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0071] In addition, in the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0072] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0073] In this application, unless otherwise clearly defined or limited, terms such as "installed", "connected", "linked", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or a communication connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0074] In this application, unless otherwise clearly defined or limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "examples", "specific examples", or "some examples", etc. means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0075] As Figures 1 to 3 shown, in an embodiment of this application, a three-dimensional garage with a lifting structure is disclosed, including a fixed support column 100, combined with Figures 4 to 7 , the support column 100 includes a first limit block 101; the three-dimensional garage further includes a lifting drive unit 200; a lifting platform 300 that can be driven by the lifting drive unit 200 to lift along the support column 100, combined with Figure 2 , the lifting platform 300 includes a positioning and blocking component 301, combined with Figure 10 , the positioning and blocking component 301 includes a positioning and blocking seat 3012 and a first telescopic unit 3011. When the first telescopic unit 3011 is in the extended state, a part of it extends out of the positioning and blocking seat 3012 and can cooperate with the first limit block 101 to prevent the downward trend of the lifting platform 300.

[0076] The above design realizes the precise stop of the lifting platform at a specified position by integrating the positioning and blocking component and the first telescopic unit, ensuring that the vehicle can be parked accurately in the parking space, and improving the use efficiency of the garage. The coordinated action of the first telescopic unit and the limit block effectively prevents the unexpected descent of the lifting platform. Even in the case of a failure of the lifting drive unit, the stability of the lifting platform can be maintained, enhancing the safety of the garage.

[0077] The combined operation of the precision positioning block assembly and the telescopic unit achieves high-precision control of the lifting platform, not only improving the operating efficiency of the garage but also reducing the risk of vehicle damage caused by control errors. This solution fully demonstrates the reliability and advantages of mechanical structures in automated equipment with high safety and reliability requirements such as three-dimensional garages, providing a solid foundation for the stable and efficient operation of the garage.

[0078] In addition, the first telescopic unit in the positioning block assembly can cooperate with the first limit block on the support column in the extended state, effectively preventing the accidental descent of the lifting platform. This mechanism can prevent rapid descent due to out-of-control or incorrect operation, reducing the impact noise generated by sudden stops.

[0079] When the lifting platform approaches the predetermined position, the contact between the first telescopic unit and the limit block enables the lifting platform to gradually decelerate and stop smoothly. This progressive stopping process is smoother than sudden mechanical braking, so the generated noise is relatively small.

[0080] The lifting drive unit is responsible for driving the lifting platform to ascend and descend along the support column, and its precise control ability ensures that the movement of the lifting platform is smooth and continuous, avoiding noise caused by speed fluctuations or unstable accelerations.

[0081] Through the coordinated work of the precise positioning block assembly and the lifting drive unit, the smooth lifting and precise stopping of the lifting platform are achieved, reducing the noise generated by impacts and vibrations. Precise positioning is very important. The lifting platform is the connection module of the three-dimensional garage. If there is an error in the positioning of the lifting platform, when other related modules, such as the car-carrying platform, operate, impacts, frictions, and unpredictable collisions will occur due to this error, and then noise will be generated.

[0082] Combined Figure 2 , the first telescopic unit 3011 cooperates with the limit block 101 in a way of fitting and pressing.

[0083] In the design of the three-dimensional garage, through the close cooperation between the first telescopic unit and the limit block, the problems of positioning accuracy and stability of the lifting platform are effectively solved. During the ascending or descending process of the lifting platform, the extended part of the first telescopic unit is in close contact with the limit block, generating physical resistance to prevent the lifting platform from exceeding the predetermined position, ensuring that it stops accurately on the correct floor and avoiding vehicle damage or safety accidents caused by inaccurate positioning.

[0084] This way of fitting and pressing makes the position control of the lifting platform more precise, and since the cooperation between the first telescopic unit and the limit block does not require a complex mechanical structure, the difficulty of maintenance and the complexity of operation are reduced, improving the reliability and durability of the system. Such a design optimizes the operating performance of the three-dimensional garage, ensuring its safety and stability during long-term operation.

[0085] Combined with Figure 10 and Figure 14 and Figure 15 , the first telescopic unit 3011 is a cam, which has a first protrusion 30111, and the first protrusion 30111 has a pressing surface that cooperates with the bearing surface of the first limiting block; when the cam rotates to the first position (refer to Figure 2 ), the first protrusion 30111 extends out of the positioning seat, and the pressing surface can be attached and pressed against the bearing surface. When the cam rotates to the second position (not shown in the figure), the first protrusion retracts into the positioning seat.

[0086] In the design of the stereoscopic garage, using a cam mechanism as the first telescopic unit effectively solves the challenges in the positioning and stability of the lifting platform. The first protrusion of the cam closely fits with the bearing surface of the limiting block, ensuring the precise stop of the lifting platform at a specific position, enabling the vehicle to be accurately parked in the predetermined parking space.

[0087] The rotation position of the cam determines the telescopic state of the first protrusion. This mechanical control method reduces the dependence on the electrical control system, simplifies the system architecture, reduces the complexity of the system and the potential failure rate. When the cam rotates to a specific position, the first protrusion and the limiting block form a firm support point, effectively preventing the unexpected descent of the lifting platform due to external forces or system failures, enhancing the stability and safety of the lifting platform.

[0088] In addition, by adjusting the design parameters of the cam (such as the protrusion height and shape), the system can adapt to diverse positioning requirements and different load conditions, improving the flexibility and adjustability of the system. This design optimizes the functionality of the stereoscopic garage, enabling it to better meet the diverse needs in practical applications.

[0089] Combined with Figure 10 and Figure 13 , a support block 30121 is arranged in the positioning seat 3012, and the cam has a second protrusion 30112; when the cam rotates to the first position, the second protrusion 30112 contacts the support block 30121 and stops the rotation trend of the cam.

[0090] In the mechanical design of the stereoscopic garage, through the cooperation of the first protrusion of the cam with the limiting block and the contact of the second protrusion with the support block, the dual positioning function of the lifting platform at a specific position is realized. When the cam rotates to the first position, the second protrusion contacts the support block, generating an additional stopping force, effectively preventing the cam from continuing to rotate due to external forces or system failures, avoiding the unexpected movement of the lifting platform, and enhancing the stability and safety of the lifting platform.

[0091] In addition, as Figure 8 , as a protection for the mechanical structure, a rain shield 3019 is also provided.

[0092] The cooperative design of the support block and the second protrusion simplifies the control system of the lifting platform, reduces the dependence on additional power sources or sensors, thereby reducing the complexity of the system and maintenance costs. The mechanical cam and support block cooperation method exhibits high durability and anti-interference ability, and can maintain stable working performance even in harsh environments, improving the reliability of the entire system. This design ensures the safe and stable operation of the stereo garage under various conditions.

[0093] Combined with Figure 10 and Figure 16 , it also includes a second limit block 3013. Refer to Figure 4 and Figure 5 , the first limit block 101 and the second limit block 102 are respectively arranged on both sides of the support column 100, and the positioning gear component 301 is located between the first limit block 101 and the second limit block 102;

[0094] The positioning gear component 301 further includes a second telescopic unit 3013. When the second telescopic unit 3013 is in the extended state, the extended part can cooperate with the second limit block 102 to prevent the downward trend of the lifting platform 300. It can be understood that the second telescopic unit cooperates with the second limit block to function in a similar principle to the cooperation of the first telescopic unit and the second limit block.

[0095] In the design of the stereo garage, the introduction of the second limit block and the second telescopic unit significantly improves the positioning accuracy and stability of the lifting platform. By arranging the first limit block and the second limit block on both sides of the support column respectively, bilateral limit control of the lifting platform is achieved, effectively coping with the external force influence that may occur during the lifting process and preventing the imbalance phenomenon caused by excessive unilateral force.

[0096] The synergistic effect of the second telescopic unit and the second limit block provides additional safety protection for the lifting platform. Even when the limit device on one side fails, the limit device on the other side can still work independently to prevent the unexpected descent of the lifting platform, thereby greatly improving the safety performance of the lifting platform. This design enhances the reliability and safety of the stereo garage, ensuring the stability of operation and the protection of vehicles.

[0097] In some embodiments, the first telescopic unit can extend and contract synchronously with the second telescopic unit.

[0098] In the design of the stereo garage, symmetrically arranging the limit mechanisms on both sides helps to simplify the control system. This design does not require complex algorithms to adjust the speed and action timing of the telescopic units on both sides, thereby reducing the complexity of the control system. At the same time, it reduces the number and complexity of the required control components, and thus reduces the maintenance costs.

[0099] To ensure the consistency of the lifting platform during vertical movement, the limit devices on both sides need to be precisely synchronized. This synchronization mechanism not only maintains the horizontal state of the lifting platform but also helps balance the load, ensuring the stable parking of the vehicle during the lifting process. The telescopic units working in synchronization enhance the reliability of the system and provide additional safety guarantees.

[0100] In case of an emergency, the limit devices on both sides can come into effect simultaneously, effectively preventing the unexpected descent of the lifting platform and significantly improving the safety performance of the lifting platform. With this design, the operation of the multi-story garage is safer and more reliable, and it also provides convenience for maintenance and operation.

[0101] Such as Figure 10 , the first telescopic unit 3011 and the second telescopic unit 3013 are both of cam structure; the positioning gear assembly 301 further includes a driving motor 3014, a transmission shaft 3015 connected to the output shaft of the driving motor 3014, the first telescopic unit or the second telescopic unit is installed on the transmission shaft (in the figure, the second telescopic unit 3013 is connected and installed to the transmission shaft 3015), a transmission gear 3016 installed on the transmission shaft 3015, and a transmission bearing seat for supporting the transmission shaft 3015; a driven shaft 3017, the second telescopic unit or the first telescopic unit is installed on the driven shaft (in the figure, the first telescopic unit 3011 is connected and installed to the driven shaft 3017), a driven gear 3018 installed on the driven shaft 3017 and meshing with the transmission gear 3016, and a driven bearing seat for supporting the driven shaft 3017.

[0102] In the mechanical system of the multi-story garage, the driving motor and the transmission system work together to ensure that the first telescopic unit and the second telescopic unit achieve precise synchronous movement. Through the cooperation of mechanical transmission devices such as the transmission shaft, transmission gear, driven shaft, and driven gear, the power of the driving motor can be efficiently and reliably transmitted to the two telescopic units, ensuring the continuity and stability of power transmission.

[0103] The design of the transmission bearing seat and the driven bearing seat provides stable support for the transmission shaft and the driven shaft, ensuring their smooth operation, thereby enhancing the stability and durability of the entire system. The design of this mechanical transmission method simplifies the electrical control system, reduces the dependence on precision sensors and complex control algorithms, and effectively reduces the design complexity and maintenance cost of the system.

[0104] Combined with Figures 4 to 7 , the support column is an H-shaped steel structure, including a web 103 and a pair of flange plates 104; the first limit block 101 and the second limit block 102 are respectively installed on the pair of flange plates 104.

[0105] In the design of a three-dimensional garage, due to the characteristics of its cross-section, the H-shaped steel structure provides excellent strength and rigidity, effectively bearing vertical and horizontal loads, and ensuring the overall stability and safety of the lifting platform. By installing the first limit block and the second limit block on the flange of the H-shaped steel, the structural advantages of the flange can be fully utilized to provide a stable support for the limit blocks and ensure precise motion control of the lifting platform during the lifting process.

[0106] As a standardized structural material, H-shaped steel is easy to purchase and process, which helps to realize the modularization and standardization of the three-dimensional garage design, thereby reducing production costs and construction difficulties. In addition, the design of the support columns of the H-shaped steel structure and the limit blocks on their flanges is convenient for inspection and maintenance. When parts need to be replaced, they can be quickly disassembled and installed, reducing downtime and improving the operating efficiency of the equipment.

[0107] In addition, as shown in the figure, the support column 100 further includes a first walking track 105 provided on the web 104 and a second walking track 106 provided on the flange 103; the lifting platform 300 has a first walking unit (not enlarged in the figure) corresponding to the first walking track 105 and a second walking unit (not enlarged in the figure) corresponding to the second walking track 106. The walking unit is, for example, a wheel or a slider.

[0108] This dual-track design not only enhances the stability of the lifting platform but also has reliability. As shown in the figure, the first walking track is a double-row track, further increasing stability. By arranging the walking track and the walking unit on the web and flange of the support column respectively, guiding and supporting from two dimensions provides a clear motion path and stable support for the lifting platform, ensuring that the lifting platform maintains the correct position and direction during vertical lifting. The clever configuration of the dual walking track and walking unit on the support column solves the balance challenges that the lifting platform may face during the lifting process. Especially when the vehicle load on the lifting platform is unevenly distributed, the walking units on both sides can ensure that the lifting platform always maintains a balanced posture.

[0109] In addition, as Figure 17 and Figure 18 , the top surface height of the first limit block 101 and / or the second limit block 102 is adjustable. The adjustment can be achieved, for example Figure 17 as shown in, by adding or subtracting multi-specification shims on the top of the limit block, or as Figure 18 shown in, by two wedges that can slide in the slot, and by adjusting the horizontal position of the lower wedge, the vertical height of the upper wedge can be finely adjusted.

[0110] The limit block may need to be replaced due to wear or damage after long-term use, which not only increases the maintenance cost but also may lead to a long downtime. In contrast, the adjustable limit block can restore its function through simple adjustment, greatly reducing the maintenance cost and downtime and improving the economic benefits of the stereoscopic garage.

[0111] During the installation and commissioning phase of the stereoscopic garage, the adjustable limit block structure greatly reduces the requirements for installation accuracy. Installers can easily adjust the limit height of the limit block to meet the parking needs of different vehicles and conveniently conduct frequent commissioning to ensure the best performance of the equipment.

[0112] The above specific implementation manners cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art of this technology, any alternative improvement or transformation made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0113] Those parts not detailed in the present utility model are all well-known technologies to those skilled in the art of this technology.
