Description

Technical Field

[0001] This utility model relates to the field of shelving technology, and more specifically, to a multi-layer beam pallet rack. Background Technology

[0002] Most existing pallet racks use a fixed structure, and their shelf height and load-bearing surface angle are usually not adjustable. This results in poor versatility when storing different types of goods, especially boxed or cartoned items that require inclined sliding for easy access. Furthermore, the fixed structure struggles to adapt to changes in goods size or specific flow requirements, thus limiting the flexibility and efficiency of warehouse space utilization. In addition, the assembly process of traditional racks is often complex, and their stability needs improvement. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-layer beam pallet rack that can flexibly adjust the layer height and tilt angle of the pallet body, and has the advantages of stable structure and convenient assembly.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a multi-layer beam pallet rack, including a support part, a pallet frame, and a pallet body. The support part includes crossbars, longitudinal bars, and a back panel. The longitudinal bars are vertically arranged and have multiple slots on their sides. The back panel is disposed between two longitudinal bars, and the two sides of the back panel have first locking plates that engage with the slots. The pallet frame has side panels on both sides, and the end of the side panel facing the longitudinal bar has an insert plate structure that can be inserted into the slot. By selecting different slots to engage with the slots, the height and tilt of the pallet rack can be adjusted. The pallet body is placed on the pallet frame.

[0005] According to one embodiment of the present invention, the insert plate structure includes a first insert plate, a second insert plate, and a third insert plate; the first insert plate has a first slot and a second slot, the second insert plate has a third slot, and the third insert plate has a fourth slot; when the first slot, the third slot, and the fourth slot are respectively connected to the corresponding slots on the longitudinal rod, the bearing surface of the pallet frame is in an inclined state; when the second slot and the third slot are connected to the corresponding slots on the longitudinal rod, the bearing surface of the pallet frame is in a horizontal state.

[0006] According to one embodiment of the present invention, the upper end face of the back plate is provided with a positioning groove, and the lower end face is provided with a positioning block adapted to the positioning groove; multiple back plates are spliced ​​together in the vertical direction by the cooperation of the positioning groove and the positioning block.

[0007] According to one embodiment of the present invention, the pallet frame is composed of side plates on both sides and multiple support columns connected between the side plates.

[0008] According to one embodiment of the present invention, a limiting plate is connected to one end of the pallet body, and the limiting plate has an L-shaped structure; the support column on the pallet frame away from the longitudinal bar is engaged with the limiting plate.

[0009] According to one embodiment of the present invention, a placement area for accommodating the trolley is provided below the support portion, and the vertical distance between the two crossbars is adapted to the width of the trolley.

[0010] In summary, this application includes at least one of the following beneficial technical effects: In this solution, multiple slots on the longitudinal bars flexibly cooperate with slots at different positions on the side plate of the pallet rack, enabling rapid adjustment of the pallet rack installation height and the tilt angle of the bearing surface. This not only meets the needs of horizontal storage but also enables inclined sliding retrieval of goods, greatly improving the adaptability of the rack to the storage of different goods.

[0011] 2. In this solution, the back panel is tightly connected to the longitudinal bar through the first clamping plate, and the upper and lower back panels are interlocked with each other through positioning grooves and positioning blocks, forming a solid three-dimensional support structure, which effectively improves the overall rigidity and load-bearing stability of the rack.

[0012] 3. In this solution, the L-shaped limiting plate on the pallet body engages with the support column of the pallet frame, which can reliably prevent the pallet from accidentally slipping when tilted or subjected to external force, ensuring storage safety. The combination of mechanical connection methods such as snap-fit ​​and plug-in eliminates the need for complicated tools, making the assembly and disassembly of the rack simple and efficient.

[0013] 4. In this solution, space is reserved at the bottom of the shelf for placing carts, so that the carts can be used as part of the shelf, realizing both the functions of goods storage and short-distance transfer, thus improving the convenience of operation. Attached Figure Description

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0018] refer to Figures 1 to 6 This embodiment provides a multi-layer beam pallet rack, including a support section on which pallet frames 4 and pallet bodies 5 are mounted. The support section consists of crossbars 1, longitudinal bars 2, and a back panel 3. Two longitudinal bars 2 are arranged vertically and parallel to each other. The bottom end of each longitudinal bar 2 is fixedly connected to two crossbars 1 by welding, thereby forming a stable bottom frame. Multiple slots 201 are uniformly machined along the length of the longitudinal bars 2 on their sides. These slots 201 can be rectangular or trapezoidal in shape. The bottom ends of the crossbars 1 and longitudinal bars 2 are then fixed by welding or bolts.

[0019] Furthermore, such as Figure 1 , Figure 2 and Figure 6As shown, the back panel 3 is used to enclose the back of the shelf and enhance the torsional rigidity of the overall structure, preventing the shelf from tilting. The back panel 3 is preferably a metal plate, with its two side edges vertically bent to form the first clamping plate 301. During installation, the operator inserts the first clamping plate 301 into the corresponding groove 201 on the vertical bar 2, either from top to bottom or bottom to top, according to the required shelf height. To achieve continuous vertical splicing of the back panels 3, a downward positioning groove is machined on the upper edge of the back panel 3, and a positioning block with a complementary shape to the positioning groove is provided on its lower edge. When two back panels 3 are spliced, the positioning block of the lower back panel 3 embeds into the positioning groove of the upper back panel 3. The cooperation between the positioning block and the positioning groove provides positioning guidance for the installation of the back panels 3, ensuring that multiple back panels 3 can be quickly aligned and kept on the same plane, improving assembly efficiency. Therefore, by setting positioning blocks and positioning grooves on the back panel 3, it is effectively prevented that adjacent back panels 3 will shift backward or left or right within their own plane, so that all back panels 3 form a stable and flat support surface. This improves the rack's resistance to bending and deformation when subjected to eccentric loads or horizontal forces.

[0020] like Figure 2 As shown, the pallet frame 4 is the component that directly supports the pallet body 5. It includes multiple insert plates and slot structures set on the side plate 401, which realizes the adjustment of the height and tilt angle of the pallet frame 4.

[0021] Specifically, the pallet frame 4 consists of side plates 401 on both sides and multiple support columns 402 fixedly connected between the side plates 401. The support columns 402 are preferably arranged in parallel to form a grid, which not only ensures the load-bearing strength, but also achieves lightweight and easy observation.

[0022] like Figure 3 and Figure 4 As shown, three independent insert plates extend from the side plate 401 facing the longitudinal rod 2: a first insert plate 4011, a second insert plate 4012, and a third insert plate 4013. These three insert plates are spaced vertically. Each insert plate has slots with different functions. The first insert plate 4011 has a first slot 40111 and a second slot 40112. The second insert plate 4012 has a third slot 40121. The third insert plate 4013 has a fourth slot 40131. These slots cooperate with the slots 201 on the longitudinal rod 2 to achieve both horizontal and inclined bearing states.

[0023] When a pallet needs to be placed horizontally to store ordinary boxed or bagged goods, align and engage the second slot 40112 and the third slot 40121 on the side plate 401 of the pallet frame 4 with the two slots 201 at the same horizontal level on the longitudinal bar 2. At this time, the two slots act as the main stress points, jointly supporting the pallet frame 4 and keeping its load-bearing surface horizontal. This two-point support structure on the pallet frame 4 ensures balanced force distribution and guarantees stable load-bearing capacity in a horizontal state. It meets the horizontal storage needs of most goods and has wide applicability.

[0024] like Figure 5 As shown, when storing goods such as vegetable and fruit boxes or other items suitable for gravity-based sliding, the pallet rack 4 can be adjusted to an inclined state. In this case, the first slot 40111, the third slot 40121, and the fourth slot 40131 are connected to three slots 201 at different heights on the vertical rod 2. Typically, the first slot 40111 is connected at the highest position, and the fourth slot 40131 is connected at the lowest position, thus creating an inclined surface on the pallet rack 4 that is lower in the front and higher in the back. Under the influence of gravity, the goods naturally slide towards the picking end, achieving first-in, first-out (FIFO) warehouse management and greatly improving picking efficiency, especially suitable for fast-turnover goods.

[0025] The pallet body 5 is placed on the pallet frame 4. To prevent the pallet body 5 from slipping due to vibration or accidental collision, especially when tilted, an L-shaped limiting plate 501 is fixedly provided at one end of the pallet body 5 near the picking end. The vertical edge of the limiting plate 501 faces the pallet frame 4.

[0026] Once the pallet body 5 is in place, its front edge sinks, causing the vertical edge of the L-shaped limiting plate 501 to be precisely positioned behind the support column 402 at the very front of the pallet frame 4, away from the longitudinal bar 2. This fundamentally prevents the pallet body 5 from accidentally moving in the picking direction, eliminating the risk of goods falling and improving operational safety.

[0027] Furthermore, when picking up or placing pallets, simply lift the front end of the pallet slightly upwards so that the limiting plate 501 passes over the support column 402 for easy pulling out or placing; the operation is simple and requires no additional steps. In addition, to improve the mobility of the shelving, a placement area for accommodating the trolley 6 is provided within the bottom space enclosed by the horizontal bars 1, vertical bars 2, and bottom back panel 3. The inner distance between the two horizontal bars 1 matches the width of the trolley 6. The trolley 6 can serve as both a shelving unit and a cargo transfer unit, saving space that would otherwise be needed for additional transfer equipment.

[0028] When it is necessary to adjust the shelf layout or clean the site, the matching trolley 6 can be easily pushed into the area, and the entire shelf can be moved using the casters of the trolley 6, which is highly flexible.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects.
