Description

Technical Field

[0001] The present invention relates to the field of conveying technology, and in particular to a vehicle conveying device for a roller-type stereo garage. Background Art

[0002] With the acceleration of urbanization and the continued growth of motor vehicle ownership, urban space resources are becoming increasingly scarce, and traditional ground-based parking methods are no longer able to meet actual needs. As a solution to save space and improve parking efficiency, multi-story parking garages have gained widespread adoption. Roller-type vehicle conveying systems, with their relatively simple structure and stable operation, are particularly crucial in multi-story parking garages. These systems primarily rely on conveyor rollers to move vehicles between lift platforms and storage platforms, and are a crucial component of multi-story parking garage automation. However, existing roller-type vehicle conveyor systems suffer from common structural issues. The drive rollers are typically linked as a single unit, meaning all rollers are driven to rotate simultaneously during operation. This means the rollers continue to idle even before a vehicle has been delivered to its intended location. This necessitates a higher-power drive unit with greater torque to drive the rollers, increasing overall system energy consumption and equipment costs. Furthermore, prolonged idling can lead to excessive mechanical wear, shortening the system's service life.

[0003] Therefore, it is necessary to provide a vehicle conveying device for a roller-type stereoscopic parking garage to solve the problem that the existing roller-type vehicle conveying system needs to provide a high-power driving device to drive the roller. Summary of the Invention

[0023] Reference Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The present invention proposes a vehicle conveying device for a roller-type stereoscopic parking garage, comprising: a base 1, wherein the base 1 is extended along a first direction; A lifting mechanism 2, comprising a lifting frame 21 and a lifting platform assembly 22, wherein the lifting frame 21 is fixedly connected to the base 1, and the lifting platform assembly 22 is slidably connected to the lifting frame 21 along the second direction, and the lifting platform assembly 22 is provided with two conveying structures 220 for conveying vehicles along the first direction; The storage mechanism 3 includes two storage mechanisms 3 symmetrically arranged on both sides of the lifting mechanism 2 along the first direction. The storage mechanism 3 includes a storage rack 31 and a plurality of storage platform assemblies 32. The storage rack 31 is fixedly connected to the base 1. The plurality of storage platform assemblies 32 are equidistantly distributed along the second direction. The storage platform assemblies 32 are fixedly connected to the storage rack 31. Along the third direction, the storage platform assembly 32 includes two storage structures 320. The two storage structures 320 correspond to the two conveying structures 220 respectively. The storage structure 320 includes a plurality of storage rollers 321 and a driving member 322 . When the conveying structure 220 conveys a vehicle that rolls over the storage rollers 321 , the storage rollers 321 are in transmission connection with the driving member 322 to move the vehicle along the rotation direction of the storage rollers 321 .

[0024] In the above embodiment, the base 1 is extended along the first direction, that is, the direction of entry and exit before the vehicle is stored. The base 1 provides an installation foundation and structural support for the entire device. The lifting mechanism 2 is arranged on the base 1, which includes a lifting frame 21 and a lifting platform assembly 22. The lifting frame 21 is fixedly connected to the base 1, and the lifting platform assembly 22 is installed on the lifting frame 21 in a sliding connection manner and can move up and down along the second direction, that is, the lifting direction. Two parallel conveying structures 220 are provided on the lifting platform assembly 22. The two conveying structures 220 correspond to the front and rear wheels of the car respectively, and are used to convey the vehicle horizontally along the first direction. The two conveying structures 220 are respectively arranged on both sides of the lifting platform assembly 22 to adapt to dual-channel storage and improve conveying efficiency. The conveying structure 220 can specifically be a roller unit composed of a plurality of conveying rollers 221, and a driving source is provided to achieve smooth movement of the vehicle along the conveying direction. The function of the conveying structure 220 is to convey the vehicle from the lifting mechanism 2 to the target storage position after the lifting platform assembly 22 is raised to the target height, or to connect the stored vehicle from the storage position to the lifting platform for subsequent delivery.

[0025] Two storage mechanisms 3 are located on either side of the lifting mechanism 2, symmetrically arranged along a first direction. Each storage mechanism 3 includes a storage rack 31 and multiple fixed storage platform assemblies 32. The storage platform assemblies 32 are evenly spaced in the vertical direction, i.e., the second direction, and are attached to the storage rack 31. They do not have the ability to move up and down. Each storage platform assembly 32 is equipped with two storage structures 320, corresponding to the two conveying structures 220 on the lifting platform assembly 22, i.e., the front and rear wheels of the vehicle. This dual-channel coordination structure allows vehicles to be transported directly from the lifting mechanism 2 to a storage location on either side, enhancing the flexibility and adaptability of the overall system operation. Each storage structure 320 is equipped with a plurality of storage rollers 321 and a drive member 322 for driving the storage rollers 321. The two storage structures 320 are arranged side by side along the third direction to support and guide the horizontal movement of the vehicle. In particular, the transmission connection between the storage roller 321 and the driving member 322 adopts a responsive linkage mechanism. Only when the vehicle is transported by the conveying structure 220 to the storage platform and rolls over the storage roller 321, the relevant storage roller 321 will establish a transmission connection with the corresponding driving member 322, thereby realizing the synchronous rotation of the storage roller 321 to complete the precise movement and positioning of the vehicle. This structure effectively avoids the inefficient operation mode in which all rollers in the system are in an unloaded state for a long time, realizes on-demand response of roller rotation, fundamentally reduces the power burden of the drive source, improves the energy utilization efficiency of the entire system, and reduces the mechanical wear problem caused by idling.

[0026] refer to Figure 5 and Figure 6In one embodiment, the storage structure 320 further includes a drive chain 323, which is connected to the output shaft of the driving member 322, and the opposite ends of the storage roller 321 are connected to drive gears 324, and along the second direction, the drive gear 324 engages or disengages with the drive chain 323.

[0027] In the above embodiment, the storage structure 320 is equipped with a drive chain 323 to achieve indirect transmission between the storage rollers 321 and the drive member 322. The drive chain 323 is fixedly connected to the output shaft of the drive member 322, forming a power input terminal. The upper surface of the drive chain 323 extends along a first direction and is configured to mesh with the drive gears 324 of the multiple storage rollers 321 in a second direction. Specifically, each storage roller 321 is fixedly connected to a drive gear 324 at opposite ends. The tooth profile, size, and mounting angle of the drive gear 324 are compatible with those of the drive chain 323, enabling transmission connection when meshed. To ensure a selective transmission effect, before the vehicle runs over the storage roller 321, the storage roller 321 is in a stationary state, and its drive gear 324 and drive chain 323 are disengaged and do not mesh. However, when the vehicle is transported by the conveying structure 220 to the storage platform and runs over the target storage roller 321, the roller shaft sinks due to external force, thereby driving the drive gear 324 into the meshing range with the drive chain 323, thereby achieving power transmission and ensuring that the relevant storage roller 321 is driven to rotate only when the vehicle is actually in place. This makes the transmission action in the system highly targeted and effectively avoids the problem of multiple rollers idling at the same time. Through the controllable meshing state between the chain and the drive gear 324, not only the energy efficiency of the device is improved, but also the operating load of the entire machine and the specification requirements of the drive components are reduced, with good structural adaptability and operating economy.

[0028] refer to Figures 5 to 7 In one embodiment, the storage structure 320 further includes a support block 325, wherein the support block 325 is connected to the storage frame 31, and a sliding hole 325a is formed in the support block 325. The storage roller 321 is inserted into the sliding hole 325a, and the storage roller 321 is slidably connected to the sliding hole 325a. A limited support portion 325b is provided in the sliding hole 325a, so that the sliding stroke of the storage roller 321 is equal to the distance between the drive chain 323 and the drive gear 324, and the sliding stroke of the storage roller 321 is smaller than the radius of the storage roller 321. The storage structure 320 further includes an elastic member 326 , and opposite ends of the elastic member 326 respectively abut against the storage roller 321 and the support block 325 .

[0029] In the above embodiment, key components such as the support block 325, the sliding hole 325a, and the elastic member 326 are used to achieve limited sliding control of the storage rollers 321 and to cooperate with the drive chain 323 to achieve dynamic engagement control. Specifically, the support block 325 is connected to the storage frame 31 and defines a vertically extending sliding hole 325a. The shafts of the storage rollers 321 extend through the sliding hole 325a and form a sliding engagement with the sliding hole 325a. A limiting support portion 325b is also provided within the sliding hole 325a. The height of this support portion ensures that the vertical sliding stroke of the storage roller 321 within the sliding hole 325a is equal to the gap between the drive gear 324 and the drive chain 323. This ensures that when the storage roller 321 is in its normal, unrolled state, its drive gear 324 is disengaged from the chain. When a vehicle rolls over the roller, the downward pressure generated causes the roller to sink, forcing the drive gear 324 to engage with the drive chain 323, establishing a transmission connection and providing support for the roller via the limiting support portion 325b. During this process, an elastic member 326 serves as a restoring mechanism, located below the storage roller 321. One end abuts the roller and the other end is fixed within the support block 325. After the vehicle leaves, the elastic member 326 automatically returns the storage roller 321 to its original, floating position, disengaging the drive gear 324 from the chain.

[0030] In one embodiment, a bearing 327 is sleeved on the outer side of the storage roller 321, and a U-shaped sliding block 328 is sleeved on the outer side of the bearing 327. The U-shaped sliding block 328 is slidably connected to the sliding hole 325a, and the bottom end of the U-shaped sliding block 328 abuts against the elastic member 326. The bottom end of the U-shaped sliding block 328 is provided with an arc-shaped limiting abutting portion 328a, and the limiting abutting portion 328a is provided corresponding to the limiting support portion 325b. The inner side of the drive chain 323 is connected to a transmission gear 329 and an adjusting gear 32a. The transmission gear 329 and the adjusting gear 32a are both arranged below the drive gear 324. The transmission gear 329 is connected to a transmission shaft 32b. The transmission shaft 32b is connected to the output shaft of the driving member 322 through a bevel gear 32c.

[0031] In the above embodiment, to further enhance the sliding precision and structural stability of the storage roller 321, a sleeve bearing 327 is provided on the outside of the storage roller 321. A U-shaped sliding block 328 is disposed externally of the bearing 327. This sliding block slidably engages with the sliding hole 325a in the support block 325. An arcuate limiter abutment 328a is provided at the bottom end of the U-shaped sliding block 328. This abutment corresponds to the limiter support 325b, limiting their sliding travel within a predetermined range and providing support for the storage roller 321 when they abut against each other. An elastic member 326 is installed between the bottom of the U-shaped slider 328 and the support block 325. When the storage roller 321 is unloaded, the elastic member 326 is preloaded, causing the U-shaped slider 328 and the roller shaft to float upward. When a vehicle runs over the storage roller 321, the elastic member 326 is compressed, causing the roller shaft to sink, driving the U-shaped slider 328 to move, causing the drive gear 324 to engage with the drive chain 323, thus transmitting power. Within the chain system, a transmission gear 329 and an adjustment gear 32a are located inside the drive chain 323 to improve transmission accuracy and adjust chain tension and height. The transmission gear 329 is connected to a transmission shaft 32b, which is connected to the output shaft of the driver 322 via a bevel gear 32c. This allows for efficient transmission of power from the driver 322 to the target storage roller 321 through a multi-stage structure. The floating design and the cushioning provided by the bearing 327 not only enhance the system's impact resistance but also effectively reduce the risk of equipment wear.

[0032] Furthermore, in the support block 325, each storage roller 321 can be disassembled separately relative to the bearing 327. When there is a problem with the operation of the roller shaft, the single roller shaft can be maintained separately in a targeted manner to achieve efficient and effective processing, making the garage operation more stable and smooth.

[0033] refer to Figure 1 and Figure 2 In one example, a lifting caisson 11 is provided on the upper end surface of the base 1, and the bottom end of the lifting frame 21 is arranged in the lifting caisson 11. The lifting platform assembly 22 includes a first state and a second state. When the lifting platform assembly 22 is in the first state, the upper end surface of the conveying structure 220 is flush with the upper end surface of the base 1. When the lifting platform assembly 22 is in the second state, the upper end surface of the conveying structure 220 is flush with the upper end surface of the storage structure 320.

[0034] In the above embodiment, the upper end surface of the base 1 is provided with a downwardly recessed lifting caisson 11, which is used to embed the lifting frame 21 part of the lifting platform assembly 22, so that the entire lifting mechanism 2 can be completely accommodated in the caisson in the first state, thereby keeping the platform surface flush with the surface of the base 1. When the lifting platform assembly 22 is in the first state, the upper end surface of the conveying structure 220 configured therein is consistent with the upper end surface of the base 1, and vehicles can directly enter or exit from the ground, ensuring smooth entry and exit and avoiding protrusions causing scratches on the vehicle chassis; when the lifting platform assembly 22 is in the second state, it is lifted to a preset height as a whole, and accurately docked with the upper end surface of the corresponding storage structure 320, so that the vehicle can smoothly transition from the conveying structure 220 to the storage structure 320, effectively improving the docking efficiency and system coordination of the vehicle during the transportation process, and meeting the precise matching requirements for multi-layer space continuous transportation paths in the stereo garage.

[0035] refer to Figure 2 and Figure 3 In one embodiment, the lifting platform assembly 22 further includes a lifting seat 23, and connecting seats 24 are provided on opposite sides of the lifting seat 23. The two connecting seats 24 are formed with downwardly bent protective portions 241 on the sides away from each other. A plurality of reinforcing portions 242 are provided in the protective portions 241, and the reinforcing portions 242 are respectively connected to the inner top surface and the inner side surface of the connecting seat 24; The four end corners on the inner side of the lifting frame 21 are each provided with a guide rod 25 extending along the second direction, and the lifting seat 23 is slidably connected to the guide rod 25 via a connecting seat 24 .

[0036] In the above embodiment, the lifting platform assembly 22 also includes a lifting base 23. Connecting bases 24 on either side of the lifting base 23 slideably engage guide rods 25 on the inside of the lifting frame 21, ensuring smooth lifting along the guide path and preventing the platform from swaying. A downwardly curved guard 241 is provided on the side of the connecting base 24 away from the center of the lifting base 23. This guard 241 physically shields foreign matter or impurities that may enter during the lifting stroke, providing protection. Several reinforcements 242 are incorporated within the guard, connecting to the inner top and inner side surfaces of the connecting base 24 to enhance overall bending and torsional resistance and strengthen the structural stability of the lifting base 23 during load-bearing operation. Guide rods 25 are positioned at the four inner corners of the lifting frame 21 along the lifting direction, forming a reliable linear guide system in conjunction with the connecting base 24 to further ensure accurate and synchronized lifting motion. This structure not only strengthens the lifting base 23's load-bearing capacity but also, through the combined action of the guard 241 and the guide structure, significantly improves stability and safety during operation.

[0037] refer to Figure 1 、 Figure 3 and Figure 8In one embodiment, the lifting platform assembly 22 also includes a bearing and rotating structure 26, which is embedded in the lifting seat 23. The bearing and rotating structure 26 includes a bearing and rotating seat 261, which is fixedly connected to the lifting seat 23. The upper end surface of the bearing and rotating seat 261 is provided with a thrust ring 262, and a sealing sleeve 263 is provided at the connection between the bearing and rotating seat 261 and the thrust ring 262. The sealing sleeve 263 and the bearing and thrust ring 262 are used to fill lubricant. The thrust ring 262 is connected to the conveying structure 220, and the thrust ring 262 is connected to the output end of the rotating power part so that the conveying structure 220 rotates synchronously with the thrust ring 262.

[0038] In the above embodiment, the lifting platform assembly 22 is embedded with a rotating structure 26 within the lifting seat 23, which is used to drive the conveying structure 220 to perform horizontal rotation. The rotating structure 26 consists of a rotating seat 261 fixedly connected to the lifting seat 23, with a thrust ring 262 disposed at its upper end. The thrust ring 262 serves as a rotational force-bearing component and is sealed with the rotating seat 261 by a sealing sleeve 263. The sealing sleeve 263 is filled with lubricant to reduce rotational friction and extend its service life. The thrust ring 262 is connected to the conveying structure 220 to form an integral rotating body. At the same time, power is input through the output shaft of the rotating power element, causing the thrust ring 262 to drive the conveying structure 220 to rotate synchronously, thereby realizing the vehicle steering and conveying function. This enables the lifting platform to not only have vertical lifting capabilities but also rotational adjustment capabilities, meeting the complex requirements of vehicle entry and exit in a multi-story parking garage, such as reversing or turning for storage and retrieval, while also improving space utilization efficiency and vehicle placement flexibility.

A shaft adjustment block is provided on the threaded structure of the lead screw 41, and each storage structure 320 in a set of storage structures 3 is fixedly connected to the shaft adjustment block. When the lead screw 41 is rotated by the lead screw 41, the threaded connection of the lead screw 41 drives the shaft adjustment block to move axially along the lead screw 41, thereby enabling precise displacement adjustment of the storage structure 320 fixedly connected thereto in the third direction. The shaft adjustment mechanism 4 allows for fine-tuning of the storage structure 320 during vehicle storage, ensuring precise docking or separation of each storage platform with the conveying structure 220. Through the high-precision adjustment of the axis adjustment mechanism 4, the storage structure 320 can be precisely adjusted on the storage platform at different heights to accommodate vehicles of different sizes or different storage and retrieval requirements.
