Description

Technical Field

[0001] This application relates to the field of automated parking system technology, and in particular to an inverted V-shaped reinforced multi-layer steel structure and an automated parking system with the same structure. Background Technology

[0002] With the continuous increase in the number of vehicles in cities, the problem of scarce urban parking resources is becoming increasingly prominent. Traditional surface parking methods occupy a large area and have low space utilization; while multi-level lift-and-slide automated parking systems are widely used in residential areas, commercial districts, factories, and other scenarios due to their high space utilization, moderate cost, and flexible installation. Among them, the multi-level steel structure frame is the core load-bearing structure of the automated parking system, which directly determines the overall stability, load-bearing capacity, and operational safety of the parking system.

[0003] In related technologies, the most common multi-level lift-and-slide automated parking systems on the market currently use a steel frame structure composed of columns and beams as the main supporting structure. Multiple columns and multiple beams are used to construct multiple load-bearing spaces, enabling a neat arrangement of multiple parking spaces, effectively utilizing vertical space, significantly increasing the number of parking spaces per unit area, and alleviating urban parking pressure. Meanwhile, the modular, assembled steel frame structure design offers advantages such as convenient assembly and disassembly, easy transportation, adaptability to different site sizes, relatively light overall weight, and short construction period. It basically meets the vehicle load-bearing and lift-and-slide operation requirements in conventional scenarios, and is currently the mainstream structural form for automated parking systems, possessing a mature application system and market adaptability.

[0004] However, existing multi-story steel structure automated parking garages have the following obvious drawbacks: the overall frame of the traditional beam-column assembled steel structure has poor rigidity, and there is a lack of effective reinforcing support structures between floors. Under the dynamic load of vehicles and outdoor wind loads, it is prone to swaying and elastic deformation. Long-term operation can easily cause loosening and wear at the connection points, resulting in weak overall resistance to deformation and crosswinds. At the same time, the stress of this type of structure is concentrated at the beam-column connection nodes, and the uneven stress distribution can easily lead to structural fatigue damage, significantly reducing structural stability and service life. Furthermore, traditional steel structures do not integrate side wall protection, roof rain shelter, and lighting supporting structures. Under outdoor conditions, the steel structure is prone to corrosion and aging, resulting in poor overall protection and practicality of the equipment, which cannot meet the requirements of long-term high-intensity, high-safety, and stable operation of automated parking garages. Summary of the Invention

[0005] To improve stability and safety, this application provides an inverted V-shaped reinforced multi-layer steel structure and a three-dimensional parking garage with the structure.

[0006] The technical solution provided in this application for an inverted V-shaped reinforced multi-layer steel structure and a three-dimensional parking garage with this structure is as follows: A multi-layered steel structure with inverted V-shaped reinforcement includes multiple columns and multiple layers of beams. The columns are arranged longitudinally and laterally along the vertical and horizontal directions of the multi-level parking garage, forming a frame extending along the height direction of the garage. The beams are horizontally fixed between two adjacent columns and arranged in layers along the height direction of the columns to form a multi-layered parking level frame. The structure also includes inverted V-shaped reinforcing trusses, side wall panels, rain shelters, and lighting components. On the outer wall of each layer of beams, multiple inverted V-shaped reinforcing trusses are arranged along the length of the beam. The two lower ends of each inverted V-shaped reinforcing truss are fixed to the outer wall of the beam in that layer, and its apex is fixedly connected to the outer wall of the beam in the corresponding upper layer. The side wall panels completely enclose the side frame of the parking level frame. The rain shelter is erected at the top of the uppermost parking level frame, and the lighting components are suspended and fixed to the outer periphery of the rain shelter.

[0007] By adopting the above technical solution, multiple inverted V-shaped reinforcing trusses are set along the length of the beam on the outer wall of each layer of crossbeams. The two ends of the trusses are fixed to the outer walls of the lower and upper layers of crossbeams, respectively, forming a continuous triangular reinforcement support system between the frames of adjacent parking layers. This effectively enhances the overall bending, shear and torsional stiffness of the multi-layer steel structure, significantly improves the structural strength of the connection nodes between the crossbeams and columns, reduces the deflection deformation of the crossbeams and inter-layer displacement, and improves the stability and load-bearing capacity of the overall frame. At the same time, the installation of side wall baffles, rain shelters and lighting components provides protection and lighting functions for the parking space, ensuring the safety and ease of use of the equipment.

[0008] Preferably, the inverted V-shaped reinforcing truss consists of two symmetrically inclined L-shaped struts. Both ends of the inverted L-shaped struts are fixedly connected to the outer wall of the corresponding crossbeam through reinforcing connecting plates. The lower ends of the two L-shaped struts are respectively fixed to the outer wall of the lower crossbeam, and the upper ends meet to form a vertex and are fixed to the outer wall of the upper crossbeam. The reinforcing connecting plate has at least two sets of bolt holes, each set containing two bolts. The bolts pass through the ends of the L-shaped struts and the reinforcing connecting plate.

[0009] By adopting the above technical solutions, on the one hand, the bending and torsional resistance of the truss is improved by utilizing the cross-sectional advantages of the L-shaped struts themselves; on the other hand, by strengthening the connection plates and multi-point bolt connections, the connection contact area and connection strength between the truss and the beams are increased, the stress at the nodes is dispersed, the stress concentration and fatigue damage at the connection points are effectively reduced, and the connection reliability and load-bearing stability of the truss nodes are significantly improved. At the same time, it is also convenient for subsequent installation, disassembly and maintenance operations.

[0010] Preferably, the outer wall of the crossbeam is provided with a plurality of H-shaped protrusions extending along the length of the beam, and the reinforcing connecting plate is fixedly installed at the joint of the H-shaped protrusions; a transverse reinforcing rod is also provided on the back of a portion of the inverted V-shaped reinforcing truss, and the two ends of the transverse reinforcing rod are respectively fixedly connected to the top of two adjacent reinforcing connecting plates to form a plurality of triangular reinforcing support structures between the two adjacent parking floor frames.

[0011] By adopting the above technical solution, the H-shaped convex edge provides a stable mounting base for the reinforcing connection plate, effectively increasing the load-bearing area of ​​the connection node, optimizing the force transmission path, and significantly improving the load-bearing strength and fatigue resistance of the truss and beam connection node; at the same time, the transverse reinforcing rod forms an effective lateral constraint on the truss node, enhancing the integrity and collaborative load-bearing capacity of the truss structure, and further improving the overall lateral stiffness and stability of the multi-story steel structure.

[0012] Preferably, the side wall baffle is a corrugated metal plate, which is continuously laid along the height direction of the multi-level parking garage and fixed to the side frame composed of the column and the beam by bolts to form a fully enclosed protective structure.

[0013] By adopting the above technical solution, the cross-sectional structural characteristics of the corrugated metal plate are used to improve the bending and impact resistance of the baffle itself. The continuous laying method forms an integral enclosure structure, which effectively blocks external debris and rainwater from intrusion, protects the internal steel structure and transmission components from corrosion and damage, and also has good sound insulation and protection effects, thus improving the safety, durability and user comfort of the multi-level parking garage.

[0014] Preferably, the rain shelter is an outward-extending color steel plate roof structure, with the edge of the roof extending outward beyond the outer contour of the column; the lighting assembly includes multiple LED floodlights, which are arranged at equal intervals along the outer periphery of the rain shelter via brackets, with the light direction downward toward the parking level frame.

[0015] By adopting the above technical solutions, the extended structure of the rain shelter can effectively block rainwater and sunlight, providing comprehensive protection for the internal parking frame and delaying the aging and wear of components; LED floodlights are evenly distributed along the edge of the roof and shine downwards, which can evenly cover the parking operation area. Sufficient and stable lighting can ensure clear visibility of vehicle storage and retrieval operations, effectively improving the safety of equipment use and the convenience of daily operation and maintenance.

[0016] A multi-level parking garage with an inverted V-shaped reinforced multi-layer steel structure includes multiple vehicle-carrying platforms, each positioned within the frame of a parking level; a lifting drive assembly installed on the top frame of the multi-layer steel structure and connected to the vehicle-carrying platforms for driving the platforms to rise and fall vertically; and a lateral movement drive assembly installed on the crossbeams of each level for driving the vehicle-carrying platforms to move and reposition horizontally.

[0017] By adopting the above technical solution, the multi-level parking garage achieves layered parking by using multi-layered vehicle carriers, effectively expanding the parking capacity. The garage relies on the lifting drive component to drive the vehicle carriers to rise and fall vertically, and cooperates with the lateral drive component to complete the horizontal displacement. Through the action logic of vertical lifting and horizontal lateral movement, the vehicle storage and retrieval scheduling operation is completed. The coordinated operation of each mechanism greatly improves the space utilization and vehicle storage and retrieval efficiency.

[0018] Preferably, the lifting drive assembly includes a lifting motor, a transmission sprocket, a lifting chain, and a guide pulley; the lifting chain is wound around the sprocket and the guide pulley, the lower end of the chain is suspended and fixed to the vehicle platform, and the lifting motor drives the sprocket to rotate, thereby driving the vehicle platform to rise and fall smoothly along the column direction.

[0019] By adopting the above technical solution, and with the help of a transmission structure consisting of a lifting motor, a transmission sprocket, a lifting chain, and a guide pulley, the vehicle platform is moved vertically by the chain suspension. The transmission structure is evenly stressed and the transmission is smooth and reliable. It can stably drive the vehicle platform to move up and down precisely along the column, and can smoothly complete the vertical transfer of vehicles. It ensures smooth operation during the lifting process, effectively avoids swaying and deviation problems, and improves the stability and operational safety of vehicle storage and retrieval operations.

[0020] Preferably, the lateral movement drive assembly includes a lateral movement guide rail, traveling rollers, a lateral movement motor, and a control junction box; the lateral movement guide rail is fixedly installed on the crossbeam, the traveling rollers are assembled at the bottom of the vehicle platform and cooperate with the lateral movement guide rail; the control junction box is installed and fixed below the H-shaped convex edge of the crossbeam, and the lateral movement motor is electrically connected to the control junction box.

[0021] By adopting the above technical solution, the lateral guide rail and the traveling roller work together to provide a regular guide for the horizontal movement of the vehicle platform, and the operation is smooth and stable. The control junction box is limited between the convex edges of the crossbeam, with a compact and reasonable layout and good protection. The lateral motor relies on electrical linkage to output driving force, which reliably drives the vehicle platform to complete the horizontal movement, ensuring the stable and orderly operation of vehicle lateral dispatching.

[0022] Preferably, the surface of the vehicle carrier plate is a non-slip corrugated steel plate, and vehicle limiting blocks are fixedly installed on both sides and the rear end of the vehicle carrier plate. The limiting blocks are raised and have their own reinforcing ribs.

[0023] By adopting the above technical solutions, the anti-slip corrugated steel plate of the vehicle platform can increase the friction of the wheel contact surface and reduce slippage when the vehicle is parked; the side and rear protrusions are equipped with limit blocks with reinforcing ribs, which can reliably limit the parking position of the vehicle. At the same time, the reinforcing ribs strengthen the structural strength of the block itself, resist the impact force generated by the vehicle parking, and effectively improve the stability of the vehicle parking and the safety of use.

[0024] Preferably, it also includes a fall protection component, which includes a protective side beam and a connecting steel rope. The protective side beam slides against the inner wall of the crossbeam and is located above the side edge of the vehicle platform. The connecting steel rope is threaded and fixed between the protective side beam and the reinforcing rib structure of the vehicle limiting block through an end hook.

[0025] By adopting the above technical solution and integrating the existing limit structure, the structure is compact and the stress points are stable. The steel rope flexible traction can form a reliable anti-fall restraint structure, which can effectively lock the vehicle platform carrying the vehicle in the event of sudden failure of the lifting chain, limit the displacement of the vehicle platform falling, avoid safety accidents caused by equipment failure, and greatly improve the overall safety and protection reliability of the lifting operation of the three-dimensional parking garage.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The steel structure relies on the combination of inverted V-shaped reinforced trusses, transverse reinforcing rods and connecting plates, and is equipped with H-shaped convex edges to stabilize the connection nodes. The overall frame has strong resistance to bending and deformation, and the components are firmly connected, which greatly improves the overall stability and load-bearing durability of the multi-level parking garage. 2. The automated parking system can smoothly complete vehicle storage and retrieval through the coordinated operation of lifting and lateral movement drive mechanisms. The vehicle platform limit and anti-slip structure regulates vehicle parking, and the anti-fall components can cope with sudden failures and avoid the risk of falling. The equipment operates stably and reliably. 3. The side wall panels and extended roof of the automated parking garage can block the erosion of wind, rain and debris, extend the service life of the equipment, and the supporting lighting components ensure the working vision. The overall protection is comprehensive, and the daily storage, retrieval and operation and maintenance experience is good. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses an inverted V-shaped reinforced multi-layer steel structure and a three-dimensional parking garage with this structure. (Refer to...) Figure 1-2 A V-shaped reinforced multi-layer steel structure includes multiple columns 1 and multiple beams 2. The columns 1 are regularly arranged longitudinally and laterally along the vertical and extend vertically in the multi-level parking garage. The beams 2 are horizontally fixed between adjacent columns 1 and arranged in layers along the height of the columns 1, together forming multiple layered multi-level parking layer frames 11, providing a basic load-bearing skeleton and structural support for layered parking of vehicles, and ensuring the basic structural stability and layered load-bearing capacity of the overall frame.

[0033] Furthermore, the steel structure also includes an inverted V-shaped reinforcing truss 3, side wall baffles 4, a rain shelter 5, and lighting components 6. The inverted V-shaped reinforcing truss 3 is arranged in layers on the outside of each layer of beams 2. Through the stable mechanical structure characteristics of the inverted V-shaped triangle, the upper and lower beams 2 are connected in an elastic way and the force transfer structure is formed. This effectively disperses the vertical load of the beams 2, alleviates the lateral torsion of the frame, and makes up for the problem of insufficient bending and lateral displacement resistance of the single-layer beam 2 structure. It also greatly improves the structural strength and deformation resistance of the layered frame.

[0034] Meanwhile, the side wall baffle 4 completely covers the side of the parking layer frame 11, forming a fully enclosed protective structure on the side of the frame. This effectively blocks external debris and wind and rain from entering the frame, and protects the steel structure frame and internal parking structure from external impact damage, ensuring a clean working environment and structural safety inside the garage. The rain shelter 5 is installed at the top of the top parking layer frame 11, providing full coverage protection for the entire upper part of the multi-level garage. This effectively resists the erosion of natural environments such as rain, sun, wind, and snow, reducing the long-term corrosion, aging, and damage to the top frame and the parking structures below due to natural climate, and extending the overall service life of the steel structure. The lighting components 6 are hoisted and fixed to the outer perimeter of the rain shelter 5. Taking advantage of the high-level layout at the top, they provide uniform lighting for the entire multi-level parking operation area of ​​the multi-level garage, meeting the lighting needs for daily parking, retrieval, and maintenance operations, and ensuring the safety and convenience of equipment operation and personnel operation.

[0035] In summary, the structure consists of columns 1 and beams 2 forming the main frame for layered parking, and relies on inverted V-shaped reinforcing trusses 3 to form an upper and lower linkage reinforcement system. By leveraging the advantages of triangular mechanics, the structure's resistance to bending, lateral displacement, and load-bearing capacity are improved, addressing the problems of weak stiffness, easy deformation, and uneven load distribution in traditional frames. Side wall baffles 4 and rain shelters 5 provide all-round protection, enhancing the structure's weather resistance and durability, and reducing maintenance costs. Top lighting components 6 complete the supporting functions. The overall layout is regular, the stress distribution is reasonable, and the reliability is high, making it suitable for the long-term use of multi-level parking garages with high-frequency vehicle storage and retrieval.

[0036] Corresponding to the above process, specifically in this embodiment, the inverted V-shaped reinforcing truss 3 is composed of two symmetrically inclined L-shaped struts 31. The struts are made of angle steel. Both ends of the inverted L-shaped struts 31 are fixedly connected to the outer wall of the corresponding crossbeam 2 through reinforcing connecting plates 32. The lower ends of the two L-shaped struts 31 are respectively fixed to the outer wall of the lower crossbeam 2, and the upper ends meet to form a vertex and are fixed to the outer wall of the upper crossbeam 2. A set of bolt holes is opened on the left and right sides of the reinforcing connecting plate 32, and each set contains two bolts. The bolts pass through the ends of the L-shaped struts 31 and the reinforcing connecting plate 32 respectively.

[0037] Therefore, by using L-shaped angle steel as support rods, utilizing its bidirectional bending and torsional resistance characteristics of its double-limb cross-section, a stable inverted V-shaped triangular force-bearing system is formed, while achieving direct bonding and fixation with the outer walls of column 1 and beam 2. This eliminates the need for additional processing of irregularly shaped connectors, simplifying the assembly process. Its lightweight and easy-to-treat corrosion characteristics reduce the additional load on the main structure, improving the overall frame's lateral displacement resistance and long-term durability, making it suitable for the multi-layered load-bearing and high-frequency use requirements of multi-level parking garages. Simultaneously, the reinforced connecting plate 32, combined with multiple sets of bolts for fastening, effectively disperses stress at connection points, reduces localized stress concentration, significantly improves the connection reliability and load-bearing stability of the truss nodes, and facilitates subsequent installation, disassembly, and maintenance.

[0038] Furthermore, in this embodiment, the crossbeam 2 is made of ultra-strong H-beam steel, with parallel flanges formed on both sides and connected in the middle by a web plate. The reinforcing connecting plate 32 is fixedly installed at the joint of the H-shaped convex edge. The back of part of the inverted V-shaped reinforcing truss 3 is also abutted by a transverse reinforcing rod 33. The two ends of the transverse reinforcing rod 33 are respectively fixedly connected to the top of two adjacent reinforcing connecting plates 32 to form multiple triangular reinforcing support structures between the two adjacent parking floor frames 11.

[0039] Therefore, the convex edge structure formed by the flanges and web of the H-beam 2 provides a stable mounting base for the reinforcing connecting plate 32, allowing the connecting plate to be firmly fixed to the beam 2 and providing reliable connection support for the inverted V-shaped reinforcing truss 3. At the same time, the added transverse reinforcing rod 33 connects the top of the adjacent connecting plates, forming a continuous triangular reinforcement support system together with the inverted V-shaped truss. This further disperses and transmits the vertical load and lateral shear force borne by the beam 2, effectively improving the overall lateral displacement resistance, bending stiffness and structural stability of the multi-story parking frame, reducing local stress concentration, and ensuring the structural safety and durability of the multi-story parking garage under long-term high-frequency load conditions.

[0040] On the other hand, the side wall baffle 4 is made of corrugated metal plate. Its corrugated structure has both rigidity and deformation resistance, and is not easily dented or deformed by wind pressure or external impact. At the same time, the corrugated metal plate is a standardized profile, which is lightweight and easy to cut and install, and is suitable for the need for large-area paving on the side of the garage. The side wall baffle 4 is laid continuously along the height direction of the multi-level garage, and can be quickly formed into a fully enclosed protection by fixing with bolts. No complicated processing is required, which combines protection and construction convenience.

[0041] In addition, the rain shelter 5 is an outward-extending color steel plate roof structure, with the edge of the roof extending outward beyond the outer contour of the column 1. The color steel plate has weather-resistant and corrosion-resistant properties, and its surface coating can resist sun exposure, rain, and temperature changes for a long time. It is not easy to rust or age. Moreover, the color steel plate is lightweight and will not bring excessive additional load to the top frame. The outward-extending edge design takes advantage of its ability to be laid over a large span to form a cantilevered protective surface that extends beyond the contour of the column 1, effectively blocking rainwater and reducing side rain from entering the garage.

[0042] Furthermore, the lighting component 6 includes multiple LED floodlights 61, which have lower energy consumption and longer service life compared to traditional lamps, making them suitable for long-term continuous use in the garage. The multiple LED floodlights 61 are arranged at equal intervals along the outer periphery of the rain shelter 5 via brackets, with the light direction pointing downwards toward the parking level frame 11. The directional downward-projected light evenly covers the multi-level parking area, ensuring the lighting needs for parking and retrieval operations, while also having low maintenance costs and eliminating the need for frequent lamp replacements.

[0043] This application also discloses a three-dimensional parking garage with an inverted V-shaped reinforced multi-layer steel structure, see reference. Figure 1-3 The multi-level parking garage is constructed using the aforementioned inverted V-shaped reinforced multi-layer steel structure to form a 3×3 parking space. The entire structure consists of nine car-carrying platforms 7, each of which is independently equipped with a lifting drive assembly 8 and a lateral movement drive assembly 9. The car-carrying platforms 7 are located within the frame 11 of each parking level. The lifting drive assembly 8 is installed on the top frame of the multi-layer steel structure and is connected to the car-carrying platform 7 for transmission, enabling the car-carrying platform 7 to be vertically lifted between different parking levels. The lateral movement drive assembly 9 is installed on the crossbeams 2 of each level, enabling the car-carrying platform 7 to move laterally between levels.

[0044] Specifically, the surface of the vehicle carrier plate 7 is made of anti-slip corrugated steel plate, which can increase the friction between the vehicle tires and the plate surface, prevent the vehicle from slipping when parking or moving, and improve the safety of the vehicle storage and retrieval process; vehicle limiting blocks 71 are fixedly installed on both sides and the rear end of the vehicle carrier plate 7. The limiting blocks 71 are raised and have a reinforcing rib structure, which can restrict the parking position of the vehicle, reduce the vehicle from going beyond the range of the vehicle carrier plate 7, and the reinforcing rib structure can improve the impact resistance of the limiting blocks 71, preventing the blocks from being deformed and damaged by the impact force when the vehicle is parked.

[0045] Specifically, the lifting drive assembly 8 includes a lifting motor 81, a transmission sprocket, a lifting chain 82, and a guide pulley. The lifting chain 82 is wound around the sprocket and the guide pulley, and the lower end of the chain suspends and fixes the vehicle platform 7. The lifting motor 81 drives the transmission sprocket to rotate, which drives the lifting chain 82 wound around the sprocket and the guide pulley to move synchronously. Under the traction of the chain, the vehicle platform 7 suspended at the lower end of the chain achieves a smooth vertical lifting action along the guide direction of the column 1.

[0046] Therefore, by combining sprocket-chain drive with guide pulleys, stable lifting and lowering of the vehicle platform 7 is achieved. The transmission structure is reliable and has a strong load-bearing capacity, which can adapt to the lifting stroke requirements of multi-level parking garages. The chain drive combined with guide pulleys reduces swaying and deviation during the lifting process, ensuring smooth operation of the vehicle platform 7. At the same time, this structure is easy to install and maintain, has high transmission efficiency, and can be adapted to high-frequency vehicle storage and retrieval operation conditions for a long time.

[0047] On the other hand, the lateral drive assembly 9 includes a lateral guide rail 91, a traveling roller 92, a lateral motor, and a control junction box 93; the lateral guide rail 91 is fixedly installed on the crossbeam 2, the traveling roller 92 is assembled on the bottom of the vehicle platform 7 and cooperates with the lateral guide rail 91; the control junction box 93 is installed and fixed below the H-shaped convex edge of the crossbeam 2, and the lateral motor is electrically connected to the control junction box 93.

[0048] Correspondingly, the control junction box 93 provides power supply and signal control channels for the transverse motor. The transverse guide rail 91 forms a guide rail extending laterally on each layer of the crossbeam 2. The traveling rollers 92 mounted at the bottom of the vehicle platform 7 are precisely matched with the transverse guide rail 91 to form a moving pair that can roll along the guide rail. When a transverse command is received, the control junction box 93 outputs a drive signal to the transverse motor. The transverse motor starts and drives the traveling rollers 92 to rotate, so that the vehicle platform 7 can move smoothly laterally between layers along the transverse guide rail 91, realizing the translational switching of the vehicle platform 7 between different parking positions and providing lateral displacement support for vehicle storage and retrieval.

[0049] Therefore, through the cooperation of the transverse guide rail 91 and the traveling roller 92, the vehicle platform 7 achieves low-resistance and stable lateral displacement within each parking frame, with no obvious jamming or deviation during operation; the control junction box 93 is installed below the H-shaped convex edge of the crossbeam 2, and the profile structure forms a natural protection, which can reduce the impact of external collisions, rainwater erosion or debris accumulation on the wiring and control components, and improve the electrical connection stability and service life of the transverse drive assembly 9; the overall structure is adapted to the continuous operation requirements of high-frequency vehicle storage and retrieval in the three-dimensional parking garage, with reliable transmission and convenient maintenance, ensuring efficient and safe operation of transverse movement between parking garage levels.

[0050] In summary, the lifting drive assembly 8 and the lateral movement drive assembly 9 work together to form a continuous "lifting-lateral movement" operation process, allowing the vehicle platform 7 to flexibly switch between different parking levels and parking positions, meeting the vehicle storage and retrieval needs of multi-level, multi-space automated parking garages. At the same time, both chain drive and roller guide rail drive have the characteristics of smooth operation, strong load-bearing capacity, and adaptability to high-frequency operation. The concealed installation of the control junction box 93 also ensures the stability of the electrical system, thus improving the overall operating efficiency and reliability of the automated parking garage.

[0051] In addition, it also includes a fall protection component, which includes a protective side beam 10 and a connecting steel rope (not shown in the attached figure). The protective side beam 10 slides against the inner wall of the crossbeam 2 and is located above the side edge of the vehicle platform 7. The connecting steel rope is threaded and fixed between the protective side beam 10 and the reinforcing rib structure of the vehicle limit block 71 through an end hook.

[0052] Correspondingly, by relying on the sliding protective side beam 10 and the connecting steel rope to form a linkage protection structure, the protective side beam 10 can only slide horizontally along the crossbeam 2 and will not rise or fall with the vehicle platform 7. It can adapt to the lateral movement of the vehicle platform 7 and does not interfere with the vertical operation. The hook is the key actuator of the mechanical anti-fall device. When the vehicle platform 7 is raised to the target position, the hook automatically embeds into the hanging ring or boss on the vehicle platform 7 under the action of spring force or gravity, forming a rigid support. The connecting steel rope is guaranteed to be stable at the connection point by the high structural strength of the reinforcing rib. When the transmission components such as the lifting chain 82 break and the vehicle platform 7 falls unexpectedly, the rope will be instantly tightened by force. The protective side beam 10 will share the falling load, effectively restrain the vehicle platform 7, prevent it from falling rapidly, reduce damage to vehicles and equipment, and greatly improve the safety and emergency protection capabilities of the three-dimensional parking garage.

[0053] Furthermore, each vehicle carrier platform 7 is equipped with a photoelectric sensor, which can detect the parking status of the vehicle on the platform 7 in real time, whether the vehicle exceeds the limit, and the position of the platform 7, and promptly feed back signals to the control system. This not only determines whether the vehicle is parked properly, reducing collisions and jamming caused by vehicles exceeding the limit, but also accurately determines the position signal of the platform 7, linking the start, stop, lifting, and lateral movements to achieve automated and orderly operation of the equipment, while also serving as a safety early warning function to reduce the risk of equipment failure and safety hazards.

[0054] The implementation principle of the inverted V-shaped reinforced multi-layer steel structure and the three-dimensional parking garage with the structure in this embodiment is as follows: In this embodiment, the inverted V-shaped reinforced multi-layer steel structure is used as the main load-bearing frame. The columns 1 and H-shaped steel beams 2 are spliced ​​to form a multi-layer three-dimensional parking frame. The inverted V-shaped reinforced truss 3 composed of L-shaped struts 31 and the transverse reinforced rods 33 are combined to form a triangular reinforcement system. The nodes are fastened with reinforced connecting plates 32 and bolts, which effectively improves the rigidity, bending resistance and lateral displacement resistance of the overall frame. The side wall corrugated metal plates and the outward-extending color steel plate rain shelter 5 respectively construct the lateral and top protection structures. With the top LED lighting components 6, the protection, weather resistance and lighting functions of the parking garage are improved. The automated parking system utilizes a steel structure with nine 3x3 vehicle-carrying platforms 7. Each platform 7 is independently equipped with a lifting drive assembly 8 and a lateral movement drive assembly 9. Relying on a sprocket, chain, and guide rail roller transmission structure, the vertical lifting and lateral movement of the platform 7 are achieved, enabling vehicle storage and retrieval operations. The platform 7 uses anti-slip corrugated steel plates and is equipped with reinforced limit blocks 71 to ensure vehicle stability. Each level's crossbeams have two horizontally sliding protective side beams 10 and connecting steel cables forming a fall protection assembly to prevent the platform 7 from accidentally falling. Simultaneously, photoelectric sensors monitor the vehicle parking status and platform 7 position in real time, linking with a control system for automated operation. The entire structure, through the coordinated efforts of main reinforcement, functional protection, drive transmission, and safety monitoring, ensures the overall structural strength and stability of the steel structure while achieving safe, efficient, and continuous vehicle storage and retrieval operations.
