Description

Technical Field

[0001] This application relates to transportation or storage devices, and more particularly to a vehicle and storage system. Background Technology

[0002] In industrial production, the ideal situation is to have a detailed division of labor, with skilled operators or specialized, highly efficient automated equipment continuously completing a certain process or part of a product. Currently, my country's logistics and transportation network is becoming increasingly developed, and the cost of long-distance transportation is constantly decreasing. This has created a situation where certain processing or product production stages can be concentrated in a centralized processing plant in a certain location, where the processing or production is completed, and then transported to the next required location.

[0003] A typical example of the above situation is the industry related to the processing of soil samples.

[0004] Whether it's controlling pollution in the living environment or maintaining and managing the environment for crop cultivation and growth, it's necessary to collect and analyze soil samples from various regions.

[0005] After soil samples are collected, they need to undergo certain processing before relevant analysis can be carried out. Soil samples retrieved from the field, after being registered and numbered, must undergo a preparation process: air-drying, grinding, sieving, mixing, and bottling, in preparation for various determinations. For example, soil heavy metals are generally analyzed using dried samples, while semi-volatile persistent organic pollutants are generally analyzed using freeze-dried samples; volatile organic pollutants are generally determined using fresh samples. Fresh samples can be temporarily stored in a refrigerator or freezer, but must be processed within 10 days.

[0006] Traditionally, soil samples are pre-treated and bottled in laboratories or testing institutions. Each laboratory or institution needs its own personnel and equipment for soil sample processing, which is suitable for small-scale soil testing but becomes time-consuming and labor-intensive for large-scale testing. An ideal approach is to set up dedicated automated processing equipment to process collected soil samples in batches using automated methods. This would allow for quick and efficient batch processing of soil samples to meet testing requirements. Furthermore, this specialized equipment can be used to centralize processing at designated locations within a region, allowing for centralized processing of all soil sample needs within that area, followed by centralized delivery and transportation. This would relieve the workload of individual testing institutions and laboratories, enabling them to focus more on soil sample testing and analysis. Obviously, this type of work requires a higher level of professionalism and knowledge from personnel. From a macro-level resource allocation perspective, this approach is more rational.

[0007] This also presents various new demands on related facilities, equipment, and personnel. On the one hand, specialized equipment and personnel are needed to efficiently process soil samples; on the other hand, centralized soil sample processing plants need to handle large quantities of samples to be processed and processed samples to be tested, necessitating the construction of dense, large-scale storage facilities. Achieving dense storage inevitably requires a large space. To make full use of this space, vertical space must be fully utilized, meaning the soil samples to be stored must be stacked high. This places demands on related facilities, requiring them to be capable of lifting and lowering for the retrieval and placement of stored samples.

[0008] Existing equipment often employs a three-dimensional lifting structure, typically consisting of one or two columns. A lifting platform is then installed on top of the columns, and a structure capable of translation or extension is set on the platform to allow for the placement and retrieval of samples at specific locations. Obviously, for dense storage scenarios, this structure places a significant load on the columns. To ensure strength, the columns must be made relatively large. Furthermore, it is difficult to support multi-station operations, meaning that only one or a batch of samples can usually be placed or retrievaled at a time.

[0009] Another approach involves setting up a lateral track, then a movable platform along the track, and finally a lifting structure on the platform. A robotic arm or other actuator for picking up and placing samples is then mounted on the lifting platform. However, this results in a higher center of gravity for the lifting structure, making it prone to tipping and requiring additional safety measures. Furthermore, the center of gravity fluctuates during lifting, necessitating additional safety measures. This increases the overall construction cost and self-load of the facility. Similarly, this structure also makes multi-station operation difficult. Summary of the Invention

[0010] This application provides a carrier and a storage system that works in conjunction with the carrier, capable of meeting the needs of dense, high-volume storage applications. The carrier can stably move and lift, reducing the overall weight load of the facility and ensuring the load is distributed as evenly as possible. Furthermore, the storage system can support multiple carriers operating simultaneously, improving the efficiency of retrieving and storing target objects such as soil samples. This addresses at least one of the aforementioned technical problems.

[0011] To achieve the above objectives, the technical solution adopted in this application is: A vehicle, including The main body includes a first mounting cavity and a second mounting cavity formed within the main body; the second mounting cavity has a mounting hole. The power supply installed in the first mounting cavity; The walking assembly installed in the second mounting cavity includes A hollow shaft is rotatably connected to the mounting hole; at least three axles are provided at the end of the hollow shaft in an isosceles right triangle arrangement, wherein a long gear is installed on the axle located at the right angle of the isosceles right triangle, and guide wheels are installed on the other two axles; A drive unit electrically connected to the power supply; the drive unit is disposed inside the hollow shaft and connected to the end of the hollow shaft, and the output shaft of the drive unit extends out of the end of the hollow shaft; A drive gear is disposed on the output shaft of the drive unit; the drive gear partially meshes with the long gear. The distance between the installation position of the guide wheel and the end of the hollow shaft is greater than the distance of the drive gear extending out of the end of the hollow shaft; the outer end of the long gear is aligned with the outer end of the guide wheel.

[0012] The vehicle moves via a walking assembly, which is powered by a power source. This assembly, in conjunction with a rack and pinion mechanism, enables the vehicle to move independently. In other words, this solution provides a moving, follow-the-vehicle drive, requiring only a mobile power source and a drive unit sufficient to power the gear set, thus achieving a lightweight design. Furthermore, the arrangement of long gears and guide wheels allows for linear movement of the vehicle with horizontally or inclined racks, as well as climbing with vertically arranged racks. Additionally, a hollow shaft, the core structure of the walking assembly, is rotatably connected to the vehicle's body, allowing adjustment of the long gear and guide wheel positions to accommodate racks at different angles.

[0013] In summary, by integrating all the functional components that drive the vehicle's movement onto the vehicle itself, and through proper design, and by using a rack that serves as both a transmission component and a guide rail, the vehicle can move in multiple directions, including translation, climbing, and hill climbing. Compared to traditional drive methods, achieving multi-dimensional transport requires lifting the entire mechanism capable of long-span translation, making it much lighter and more flexible. This reduces the overall weight and self-load of the vehicle and its associated structures, allowing for faster operation while maintaining a lightweight design.

[0014] In a preferred implementation, the number of axles is four, and the four axles are arranged in a square, wherein guide wheels are installed on three of the axles.

[0015] In a preferred embodiment, the guide wheel is a short gear, which has the same specifications as the long gear, and the width of the short gear is smaller than that of the long gear.

[0016] In a preferred implementation, in the square, at least one of the guide wheels arranged with the long gear is a short gear, the short gear has the same parameters as the long gear, the width of the short gear is smaller than that of the long gear, and the other two guide wheels are driving wheels.

[0017] In a preferred embodiment, the mounting hole is provided with a hub and a bearing, the inner ring of the bearing mates with the hollow shaft, and the outer ring of the bearing mates with the hub.

[0018] In a preferred implementation, the main body includes A square base plate; Two pairs of side plates connected to the edge of the base plate, the two pairs of side plates forming a cavity; A pair of first partitions are disposed above the base plate, and the pair of first partitions divide the cavity into two second mounting cavities located at both ends of the main body; The mounting holes formed by the second mounting cavity are located on one of a pair of side plates; the axes of the two mounting holes are the same; The mounting cavity is also equipped with a braking unit, which is matched with the hollow shaft installed in the two mounting holes.

[0019] In a preferred embodiment, a second partition is further included between the two first partitions, the second partition and the two first partitions together dividing the cavity into a first mounting cavity and a third mounting cavity.

[0020] The technical solution also provides a storage system, including As mentioned above, vehicles; Storage rack, the storage rack includes Several pillars, A crossbeam and a longitudinal beam connected to the column; the crossbeam includes a bottom crossbeam and a supporting crossbeam located above the bottom crossbeam; rack assembly, the rack assembly comprising A lifting rack is mounted on the column and can mesh with the long gear; A translation rack that can mesh with a long gear is disposed on the bottom crossbeam; A turntable is provided at the intersection of the lifting rack and the translation rack, and a steering rack is provided on the turntable. The steering rack has the same specifications as the lifting rack and the translation rack.

[0021] By coordinating the storage rack with the vehicle, the vehicle can move laterally and longitudinally within the storage rack. The storage rack only requires a rack for transmission and guidance, significantly reducing the load on the rack itself. This allows the storage rack to be erected higher and stores larger quantities of items. The vehicle itself can also operate flexibly and smoothly. When climbing is needed, it can move to the turntable position and rotate the steering rack to change the angle of the walking components, switching from translation to lifting – very convenient. Furthermore, it supports the simultaneous operation of multiple vehicles, enabling more efficient storage of items.

[0022] In a preferred implementation, the number of storage racks is two or more; Two or more of the storage racks are aligned and the spacing between adjacent storage racks satisfies the following condition: the long gears in the traveling assemblies on both sides of the vehicle can simultaneously mesh with the racks in the rack group located on the opposite side of the adjacent storage racks.

[0023] In a preferred implementation, the steering rack, the lifting rack, and the translation rack are all double-sided racks; The guide wheels are all short gears with the same specifications as the long gears. Attached Figure Description

[0025] To more clearly illustrate the overall concept of this application, a detailed explanation will be provided below with reference to the accompanying drawings.

[0026] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In this application, unless otherwise expressly specified and limited, "upper" or "lower" of the first feature and the second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two entities connected are not linked by an intermediate structure, but rather form a whole through a connecting structure. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] In this application, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0030] Combination Figures 7 to 9 In one embodiment, a carrier 100 is disclosed, including a main body 110, a first mounting cavity 1101 and a second mounting cavity 1102 formed in the main body 110; the second mounting cavity 1102 is formed with a mounting hole 11021; and a power supply 120 is installed in the first mounting cavity 1101. The walking assembly 130 installed in the second mounting cavity 1102 includes a hollow shaft 1301, which is rotatably connected to the mounting hole 11021. At least three axles 1302 arranged in an isosceles right triangle are provided at the end of the hollow shaft 1301. A long gear 1304 is installed on the axle located at the right angle of the isosceles right triangle, and guide wheels 1303 are installed on the other two axles 1302. A drive unit 1305 is electrically connected to a power supply 120; the drive unit 1305 is disposed inside a hollow shaft 1301 and connected to the end of the hollow shaft 1301, and the output shaft of the drive unit 1305 extends out of the end of the hollow shaft 1301. A drive gear 1306 is disposed on the output shaft of the drive unit 1305; the drive gear 1306 partially meshes with the long gear 1304. The distance between the installation position of the guide wheel 1303 and the end of the hollow shaft 1301 is greater than the distance of the drive gear 1306 extending out of the end of the hollow shaft 1301; the outer end of the long gear 1304 is aligned with the outer end of the guide wheel 1303.

[0031] The vehicle moves via a walking assembly, which is powered by a power source. This assembly, in conjunction with a rack and pinion mechanism, enables the vehicle to move independently. In other words, this solution provides a moving, follow-the-vehicle drive, requiring only a mobile power source and a drive unit sufficient to power the gear set, thus achieving a lightweight design. Furthermore, the arrangement of long gears and guide wheels allows for linear movement of the vehicle with horizontally or inclined racks, as well as climbing with vertically arranged racks. Additionally, a hollow shaft, the core structure of the walking assembly, is rotatably connected to the vehicle's body, allowing adjustment of the long gear and guide wheel positions to accommodate racks at different angles.

[0032] In summary, by integrating all the functional components that drive the vehicle's movement onto the vehicle itself, and through proper design, and by using a rack that serves as both a transmission component and a guide rail, the vehicle can move in multiple directions, including translation, climbing, and hill climbing. Compared to traditional drive methods, achieving multi-dimensional transport requires lifting the entire mechanism capable of long-span translation, making it much lighter and more flexible. This reduces the overall weight and self-load of the vehicle and its associated structures, allowing for faster operation while maintaining a lightweight design.

[0033] Combination Figures 14 to 18 There are four axles 1302 arranged in a square, and guide wheels 1303 are mounted on three of the axles 1302. Alternatively, it can be arranged as follows... Figure 19 As shown, only three axles are installed, arranged in an isosceles right triangle. A four-axle arrangement would provide more stable guidance and support.

[0034] As shown in the figure, guide wheel 1303 is a short gear, which has the same specifications as long gear 1304, but the width of the short gear is smaller than that of long gear 1304. (Combined) Figure 2 The short gear acts as a guide wheel and works with the long gear. Whether there are three or four, they can clamp the double-sided gears in two directions, resulting in double-sided meshing and greater stability. When the vehicle stops, the vehicle's position can also be stably locked.

[0035] In an embodiment not shown in the figure, the guide wheel can be a walking wheel, and the rack that cooperates with the walking component is set as a single-sided rack, as a more streamlined design. That is, in the square, at least one of the guide wheels 1303 arranged with the long gear 1304 is a short gear, the short gear has the same parameters as the long gear 1304, the width of the short gear is smaller than that of the long gear 1304, and the other two guide wheels 1303 are walking wheels.

[0036] Combination Figure 8 , Figures 14 to 18 The mounting hole 11021 is provided with a hub 1307 and a bearing 1308. The inner ring of the bearing 1308 mates with the hollow shaft 1301, and the outer ring of the bearing 1308 mates with the hub 1307.

[0037] The hollow axle structure is supported by a hub and can rotate on the vehicle. This means the gear train at the end of the hollow axle can also rotate. When the gear train engages with the rack and pinion, its orientation can be determined, and it can also be used for steering when needed. Figures 10 to 15 The hollow shaft has two vertical ribs at its end, and a strip-shaped mounting plate is fixed to it through the connecting holes on the end face of the hollow shaft and the vertical ribs. The axle can be fixed on the mounting plate. The interior of the hollow shaft can accommodate a motor as a drive unit.

[0038] Combination Figures 7 to 9 The main body 110 is a steel box structure formed by welding, riveting, or threading plate together. The cover plate structure of the main body is not shown in the figure. A cover plate can be set on the top of the main body as needed to install structures such as handling robots. Alternatively, it can be partially covered to install functional components inside the main body. At the same time, weight-reduction holes can be evenly opened on all the plates of the steel structure to reduce the overall weight of the vehicle and to help the power supply, motor and other components inside the vehicle to dissipate heat quickly.

[0039] As shown in the figure, the main body 110 includes a square base plate 1101; two pairs of side plates 1103 connected to the edge of the base plate 1101, the two pairs of side plates 1103 forming a cavity; a pair of first partitions 1104 disposed above the base plate 1101, the pair of first partitions 1104 dividing the cavity into two second mounting cavities 1102 located at both ends of the main body 110; mounting holes 11021 formed by the second mounting cavities 1102 are located in one of the pair of side plates 1103; the axes of the two mounting holes 11021 are the same; a braking unit 140 is also disposed in the mounting cavity, the braking unit 140 simultaneously matching the hollow shaft 1301 installed in the two mounting holes 11021.

[0040] The main body of the vehicle is constructed from plate steel, making it lightweight, high-strength, and with a reasonable weight distribution. The arrangement of the mounting cavities ensures even load distribution. The four walking components can bear the load evenly. It should be noted that the hollow shaft sections of two walking components are omitted to more clearly illustrate the overall structure of the vehicle; this is not to demonstrate the actual structure of the proposed solution.

[0041] The braking unit can be set one for each traveling component or one for a pair of traveling components to achieve synchronous braking. The structure of the braking unit can refer to various existing electric brake structures, which will not be elaborated here.

[0042] Referring to the accompanying drawings, the system also includes a second partition 1105 located between the two first partitions 1104. The second partition 1105, together with the two first partitions 1104, divides the cavity into a first mounting cavity 1101 and a third mounting cavity 1106. The third mounting cavity can serve various functions; it can be installed in a control unit to control the vehicle's drive, or it can be installed in a robotic arm or other loading / unloading devices and structures, its placement determined by weight. In some embodiments, a backup power supply can also be placed there.

[0043] As part of the equipment used in conjunction with the vehicle, a storage system was also revealed, such as Figures 1 to 3As shown, the system includes a carrier 100; a storage rack 200, which includes several columns 210, a crossbeam 220 and a longitudinal beam 230 connected to the columns 210; the crossbeam 220 includes a bottom crossbeam 2201 and a support crossbeam 2202 located above the bottom crossbeam 2201; a rack assembly, which includes a lifting rack 2101 mounted on the columns 210 and capable of meshing with a long gear 1304; and a translation rack 2303 mounted on the bottom crossbeam and capable of meshing with the long gear 1304; a turntable 240 is provided at the intersection of the lifting rack 2101 and the translation rack 2303, and a steering rack 2401 is provided on the turntable 240, the steering rack 2401 having the same specifications as the lifting rack 2101 and the translation rack 2303.

[0044] Combination Figure 2 The steering rack 2401, lifting rack 2101 and translation rack 2303 are all double-sided racks; the guide wheels 1303 are all short gears with the same specifications as the long gear 1304.

[0045] By coordinating the storage rack with the vehicle, the vehicle can move laterally and longitudinally within the storage rack. The storage rack only requires a rack for transmission and guidance, significantly reducing the load on the rack itself. This allows the storage rack to be erected higher and stores larger quantities of items. The vehicle itself can also operate flexibly and smoothly. When climbing is needed, it can move to the turntable position and rotate the steering rack to change the angle of the walking components, switching from translation to lifting – very convenient. Furthermore, it supports the simultaneous operation of multiple vehicles, enabling more efficient storage of items.

[0046] In the above scheme, the vehicle works in conjunction with a separate storage rack. In a more common scenario, such as... Figure 4 and Figure 5 As shown, there are two or more storage racks 200; the two or more storage racks 200 are aligned, and the spacing between adjacent storage racks 200 is such that the long gears 1304 in the traveling components 130 on both sides of the vehicle 100 can simultaneously mesh with the racks in the rack group located on the opposite side of the adjacent storage racks 200. The side-by-side storage racks can jointly support the vehicle running between two adjacent storage racks, making it more stable and utilizing space more effectively, which is conducive to achieving dense storage.

[0047] In addition, combined Figure 5 and Figure 6Alternatively, an RGV system can be installed on one side of multiple side-by-side storage racks. This system uses tracks to transport vehicles between different storage racks. A rack or pinion is installed on the RGV, allowing the vehicle to move from the RGV to the storage rack. This enables a highly dense storage system with multiple vehicles capable of high-speed operation between storage racks, meeting the needs of dense storage, especially in scenarios requiring centralized batch processing of soil samples.
