Description

Technical Field

[0001] The present invention relates to the technical field of logistics transportation, and specifically relates to a logistics rack for transporting logistics boxes. Background Art

[0002] Logistics is the whole process of physical flow in which goods are transferred from the supply place to the receiving place, running through all links of goods circulation. According to actual operation requirements, multiple basic functions such as transportation, storage, loading and unloading, handling, packaging, distribution processing, distribution, and information processing can be overall planned and organically integrated to form a complete logistics operation system. Transportation is a basic logistics activity that uses various transportation tools to complete the cross-regional spatial displacement of passengers or goods. In the storage and warehousing link of the logistics system, logistics racks are indispensable special warehousing equipment, mainly used for regular stacking and temporary storage of various goods during logistics transportation and waiting for sorting and distribution, rationally utilizing warehousing space, facilitating the classified management of goods, quick access and turnover, and effectively improving warehousing utilization rate and overall logistics turnover efficiency.

[0003] Traditional logistics racks for transporting logistics boxes mainly consist of a frame body, load-bearing crossbeams, support columns, bottom anti-slip bases, and limit bars. The whole is formed by welding metal profiles, with a stable structure and strong bearing capacity, and can be used to place logistics boxes in layers regularly. When in use, first place the logistics rack stably on a flat ground, check whether the frame is deformed and whether the welds are firm; then, in accordance with the principle of placing lighter items on top and heavier items at the bottom and classifying and zoning, place the logistics boxes on the crossbeams of the rack in sequence, and use the limit bars to prevent the boxes from slipping and tipping; after placing, stack them neatly within the rated height and load limit of the rack; finally, it can be transported integrally with a forklift or manually. During transportation, rely on the overall structure of the rack to fix the boxes, avoid mutual collision and extrusion and slipping of the logistics boxes, and realize the integration of warehousing stacking and transfer operations, improving the stability and safety of the turnover and transportation of logistics boxes.

[0004] Existing logistics racks are an essential part of modern industrial warehouses, logistics centers, and distribution centers. The push-back rack, also known as the drive-in rack, has multiple trolley layers overlapping between the front and rear beams. Stacked goods are placed on the pallet trolley and pushed in from the outside, and the stored goods will push the original goods inside. It is suitable for storing goods in large quantities with few varieties, with high space utilization rate and flexible access. However, when used in a fresh food warehouse, due to the long-term low-temperature and high-humidity environment in the fresh food warehouse, water vapor is easily condensed on the ground to form a water film, greatly increasing the smoothness of the ground itself. After the rollers at the bottom of the rack come into contact with the wet ground, a lubricating water layer will form on the contact surface, reducing the frictional resistance between the rollers and the ground. During the process of pushing and pulling the goods into and out of the rack, the rollers cannot form effective grip, resulting in idling, deviation, and slipping phenomena, not only causing inaccurate positioning of the goods being pushed, but also easily leading to the dumping and collision damage of the goods. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is: when used in fresh food warehouses, because fresh food warehouses are in a low temperature and high humidity environment for a long time, water vapor is easily condensed on the ground to form a water film, and the smoothness of the ground itself is greatly increased. After the rollers at the bottom of the shelves come into contact with the wet ground, a layer of lubricating water will form on the contact surface, reducing the frictional resistance between the rollers and the ground. During the movement of goods pushing into and pulling out of the shelves, the rollers cannot form an effective grip, resulting in free spinning, deviation and slippage. This not only causes inaccurate positioning of goods, but also easily leads to the tipping and collision damage of goods.

[0006] The technical solution adopted by this application to solve its technical problem is: a logistics box transport rack, including support rods, a connecting frame fixedly installed on the support rods, a crossbar fixedly installed between two adjacent support rods, and a storage box slidably installed on the crossbar. The storage unit includes a support bar movably disposed on the crossbar, one end of the support bar being fixedly provided with an upper hook, and the other end of the support bar being fixedly provided with a lower hook; An anti-slip unit includes a connecting shaft fixedly mounted on the support rod, a bracket fixedly mounted on the connecting shaft, a protective shell fixedly mounted on the bracket, a rotating shaft rotatably mounted on the bracket, a caster fixedly mounted on the rotating shaft, a sleeve rotatably mounted on the outer circumference of the rotating shaft, a fixed plate height-mounted on the outer circumference of the sleeve, and cleaning rollers rotatably mounted on both ends of the fixed plate.

[0007] Preferably, a card plate is fixedly installed on the crossbar, a conveying plate is fixedly installed on the card plate, and a storage box is slidably installed between two adjacent conveying plates. A pulley is rotatably installed inside the conveying plate, and the conveying plate is inclined.

[0008] Preferably, a torsion spring is fixedly provided at the axle of the caster, and a circular plate is fixedly provided at the other end of the torsion spring, with the circular plate and the side wall of the sleeve fitting together.

[0009] Preferably, anti-slip ridges are fixedly provided on the outer peripheral surface of the caster, and the multiple anti-slip ridges are evenly distributed among each other, and the anti-slip ridges are arranged in a bent W shape, with equal spacing between two adjacent anti-slip ridges.

[0010] Preferably, limit frames are fixedly provided on both ends of the fixed plate, the cleaning roller is rotatably connected to the limit frames, and the diameter of the cleaning roller is smaller than the diameter of the caster. A pulley is fixedly provided at the axis of the side wall of the cleaning roller, and the two pulleys are connected by belt drive.

[0011] Preferably, a guide plate is fixedly provided on the protective shell, both cleaning rollers are slidably connected to the guide plate, a slide plate is fixedly provided on the limiting frame, an exhaust pipe is fixedly provided on the slide plate, and the exhaust pipe is located above the cleaning rollers. An air inlet is provided at the connection between the exhaust pipe and the slide plate.

[0012] Preferably, the exhaust pipe has a fixed air outlet at its bottom end, and the multiple air outlets are evenly distributed among each other. The air outlets are arranged in a frustum shape with a smaller top and a larger bottom. The distance between two adjacent air outlets is equal, and the slide plate is slidably connected to the guide plate.

[0013] Preferably, an air guide plate is fixedly installed on the side wall of the guide plate, an air supply pipe is fixedly installed on the two air guide plates, and an air inlet pipe is fixedly installed on the air supply pipe.

[0014] Preferably, a collection plate is fixedly installed inside the protective shell, the bottom end of the collection plate is arc-shaped, and a scraping opening is provided on the collection plate.

[0015] Preferably, the bottom of the collecting plate is inclined.

[0016] The beneficial effects of this application are: 1. When placing the storage box containing fresh products on the conveyor plate and support bar of the device, the inclined conveyor plate allows the storage box to slide down the pulley on the conveyor plate by its own weight, making it convenient for staff to place materials. The support bar with upper and lower hooks can achieve quick disassembly. 2. When the entire device moves, the casters will rotate. During the rotation of the casters, the torsion springs fixed to the side walls of the casters will also rotate synchronously. Under the action of the torsion springs themselves, the circular plate will rotate. The rotating circular plate can drive the sleeve to rotate laterally through the squeezing force, causing the fixed plate to tilt in the direction of the device's movement. As a result, the cleaning roller on one end will contact the ground. During the contact between the cleaning roller and the ground, the section that the casters will pass through can be cleaned, increasing the friction between the casters and the ground. When the fixed plate tilts, the sliding plate fixed to the limit frame slides along the guide plate. At this time, the cleaning roller that is in an idle state can be driven by another rotating cleaning roller through the belt. When the air inlet on the sliding plate is connected to the air guide plate, the dry gas will enter the exhaust pipe and be sprayed out through the air outlet to dry the surface of the cleaning roller. At the same time, the rotating cleaning roller will contact the scraper on the collection plate, and the fixed impurities adhering to the surface of the cleaning roller will be scraped off through the scraper. The collection plate has a certain height difference to facilitate the free scattering of impurities. Attached Figure Description

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] Reference Figures 1-8A logistics box transport rack includes support rods 1, which include multiple vertically arranged support rods 1. Each support rod 1 serves as an overall support frame, playing a role in vertical load-bearing and stable positioning. A connecting frame 11 is fixedly installed on the support rod 1. The connecting frame 11 adopts a stable connection structure to realize the lateral tie positioning between each support rod 1, thereby enhancing the structural rigidity and integrity of the overall frame. A crossbar 12 is fixedly installed between two adjacent support rods 1.

[0022] Reference Figures 1-3 A clamping plate 121 is fixedly installed on the crossbar 12, and a conveying plate 13 is fixedly installed on the clamping plate 121. The clamping plate 121 is firmly attached to the crossbar 12, serving as a positioning support and limiting connection. The conveying plate 13 is securely installed and fixed by the clamping plate 121, and a storage box 2 is slidably installed between two adjacent conveying plates 13. A pulley 131 is rotatably installed inside the conveying plate 13, and the conveying plate 13 is inclined. The pulley 131 can rotate flexibly, greatly reducing the frictional resistance when the storage box 2 slides. At the same time, the conveying plate 13 adopts an inclined structure, using its own inclination angle to form a natural guide. With the assistance of the pulley 131, the storage box 2 can slide smoothly by its own weight, making storage and retrieval effortless and smooth, and improving the efficiency of logistics box turnover operations.

[0023] A storage bin 2 is slidably mounted on the crossbar 12. The storage bin 2 can slide smoothly in and out along the axis of the crossbar 12, which facilitates the neat storage, layered organization, and rapid push-pull transfer of logistics boxes, and is suitable for the bulk stacking and turnover transportation needs of warehouse logistics boxes. The storage unit includes a support bar 21 movably mounted on the crossbar 12. One end of the support bar 21 is fixedly provided with an upper hook 211, and the other end of the support bar 21 is fixedly provided with a lower hook 212. The anti-slip unit and the protective unit include a connecting shaft 4 fixedly mounted on the support rod 1, a bracket 41 fixedly mounted on the connecting shaft 4, a protective shell 3 fixedly mounted on the bracket 41, a rotating shaft 411 rotatably mounted on the bracket 41, and a caster 6 fixedly mounted on the rotating shaft 411.

[0024] Reference Figures 5-6 A torsion spring 62 is fixedly installed at the axle of the caster 6, and a circular plate 63 is fixedly installed at the other end of the torsion spring 62. The circular plate 63 is in contact with the side wall of the sleeve 9. During the rotation of the caster 6, the torsion spring 62 fixedly connected to the side wall of the caster 6 will also rotate synchronously. Under the action of the torsion spring 62's own torque, the circular plate 63 will rotate. The rotating circular plate 63 can drive the sleeve 9 to rotate laterally through the extrusion force, causing the fixed plate 91 to tilt in the direction of the device's movement.

[0025] Reference Figure 7Anti-slip ribs 61 are fixedly provided on the outer circumferential surface of the caster 6. The anti-slip ribs 61 on the outer circumferential surface of the caster 6 can increase the friction between the caster 6 and the warehouse floor, thereby ensuring the stability and safety of the device during transfer. Multiple anti-slip ribs 61 are evenly distributed and are arranged in a bent W shape. The distance between two adjacent anti-slip ribs 61 is equal. The W-shaped bent structure can engage multiple contact surfaces, effectively playing an anti-slip and anti-slip role, avoiding slippage and displacement, and further improving the overall stability of placement and operation.

[0026] A sleeve 9 is rotatably mounted on the outer circumference of the rotating shaft 411. A fixing plate 91 is mounted at a height on the outer circumference of the sleeve 9. Cleaning rollers 5 are rotatably mounted on both ends of the fixing plate 91.

[0027] Reference Figures 6-8 Limit frames 92 are fixedly installed on both ends of the fixed plate 91. The cleaning roller 5 is rotatably connected to the limit frame 92, and the diameter of the cleaning roller 5 is smaller than the diameter of the caster 6. The device is stable and safe to operate by setting the size relationship between the various components. A pulley 51 is fixedly installed at the axis of the side wall of the cleaning roller 5, and the two pulleys 51 are connected by belt drive. When the fixed plate 91 tilts, the slide plate 921 fixed on the limit frame 92 slides along the guide plate 31. At this time, the tilted cleaning roller 5 is in an idle state and can be driven by another rotating cleaning roller 5 through the belt.

[0028] Reference Figures 5-7 A guide plate 31 is fixedly installed on the protective shell 3. Both cleaning rollers 5 are slidably connected to the guide plate 31. A sliding plate 921 is fixedly installed on the limiting frame 92. An exhaust pipe 93 is fixedly installed on the sliding plate 921 and is located above the cleaning rollers 5. An air inlet 931 is opened at the connection between the exhaust pipe 93 and the sliding plate 921. When the air inlet 931 on the sliding plate 921 is connected to the air guide plate 71, the dry gas will enter the exhaust pipe 93 and be sprayed out through the air outlet 932 to dry the surface of the cleaning rollers 5.

[0029] Reference Figures 5-8 The exhaust pipe 93 has an air outlet 932 fixedly installed at the bottom end, and multiple air outlets 932 are evenly arranged. The air outlets 932 are truncated pyramidal in shape with a small top and a large bottom. The distance between two adjacent air outlets 932 is equal. The slide plate 921 is slidably connected to the guide plate 31. The air outlet 932 adopts a truncated pyramidal structure design with a small top and a large bottom, and has a gradually changing shape that is narrow at the top and wide at the bottom. This not only can evenly distribute the exhaust airflow, but also reduce the exhaust flow rate and buffer the air pressure, avoiding the concentrated direct impact of the airflow and causing disturbance. At the same time, the truncated pyramidal shape can expand the exhaust coverage area, making the exhaust more dispersed and gentle.

[0030] Reference Figures 5-7An air guide plate 71 is fixedly installed on the side wall of the guide plate 31. An air supply pipe 7 is fixedly installed on the two air guide plates 71. An air inlet pipe 72 is fixedly installed on the air supply pipe 7. The air inlet pipe 72 installed on the air supply pipe 7 facilitates its connection with an external air supply system.

[0031] Reference Figures 6-8 A collection plate 8 is fixedly installed inside the protective shell 3. The collection plate 8 is securely embedded in the inner cavity of the protective shell 3, serving to receive and collect impurities. The bottom of the collection plate 8 adopts an arc-shaped structure design with smooth transitions, facilitating the gathering and collection of impurities. The surface of the collection plate 8 has regular scraping grooves 81, and the bottom of the collection plate 8 is inclined, forming a natural downward slope. During operation, the outer wall of the rotating cleaning roller 5 can precisely contact the scraping grooves 81 on the collection plate 8. As the cleaning roller 5 continues to rotate, the cleaning roller 5 is made of highly absorbent plush material. The scraping grooves 81 can scrape off stubborn impurities and dirt adhering to the roller surface in real time. The collection plate 8 has a reasonable height difference, which, together with the arc-shaped bottom and the inclined plate surface, forms a guiding structure. The scraped impurities can slide naturally down the plate surface by their own gravity and be collected, preventing accumulation and ensuring continuous and smooth impurity removal, thus improving the overall cleaning effect.

[0032] Specifically, the solution is as follows: First, the operator places the device in a predetermined position. Then, the storage box 2 containing fresh produce is placed on the conveyor plate 13 and support bar 21 of the device. Due to the inclined conveyor plate 13, when the storage box 2 is placed on it, it slides downwards along the pulley 131 on the conveyor plate 13 under its own weight, facilitating material placement. The support bar 21, equipped with upper hooks 211 and lower hooks 212, allows for quick disassembly. When the entire device is moved, the casters 6 rotate. During the rotation of the casters 6, the torsion spring 62, fixedly connected to the side wall of the casters 6, also rotates synchronously. Under the torsion of the torsion spring 62, the circular plate 63 rotates. The rotating circular plate 63, through the squeezing force, causes the sleeve 9 to rotate laterally, moving the fixed plate 91 towards the device. The direction of the cleaning roller 5 tilts, and one end of the cleaning roller 5 contacts the ground. During the contact between the cleaning roller 5 and the ground, the section of road that the caster 6 will pass through can be cleaned, and the friction between the caster 6 and the ground can be increased. When the fixed plate 91 tilts, the slide plate 921 fixed on the limit frame 92 slides along the guide plate 31. At this time, the cleaning roller 5 that is tilted is idle and can be driven by another rotating cleaning roller 5 through the belt. When the air inlet 931 on the slide plate 921 is connected to the air guide plate 71, the dry gas will enter the exhaust pipe 93 and be sprayed out through the air outlet 932 to dry the surface of the cleaning roller 5. At the same time, the rotating cleaning roller 5 will contact the scraper 81 on the collection plate 8. The scraper 81 will scrape off the fixed impurities that are attached to the surface of the cleaning roller 5. The collection plate 8 has a certain height difference to facilitate the free scattering of impurities.

[0033] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary. Under the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.

[0034] This invention is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
