Description

Technical Field

[0001] This application relates to the field of logistics and warehousing technology, and in particular to a shelf and its load-bearing crossbar. Background Technology

[0002] With the rapid development of the logistics industry, warehousing systems are also constantly being innovated. Warehousing systems in related technologies generally include storage racks, which consist of multiple layers of horizontal frames for storing materials, with multiple storage positions set on the horizontal frames.

[0003] In existing technologies, the crossbeams of warehouse racks can only support a limited amount of material. When there is a large amount of material, the number of racks needs to be continuously increased to accommodate more material, resulting in racks occupying a large amount of space and incurring high costs. In existing warehouse racking technology, conventional designs generally adopt a layout pattern where a single layer of beams corresponds to a single layer of goods. Although the industry has attempted to improve storage density by optimizing beam dimensions or shelf structure, it has not yet been able to break through the 1:1 correspondence between beam levels and goods levels.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0046] To reduce the floor space occupied by shelves when storing the same amount of materials and lower warehousing costs, this application provides a shelf and its load-bearing crossbars. The details are described below.

[0047] See Figures 1a to 2 , Figure 1a A side view of the shelving and material assembly provided in an embodiment of this application; Figure 1b for Figure 1a The first rack in the shelf shown is a side view of the material assembly. Figure 2 for Figure 1a The isometric view of the shelf in the illustrated embodiment; as shown Figure 1a , Figure 1b and Figure 2 As shown, an embodiment of the first aspect of this application provides a shelf 1, which includes: a supporting vertical frame 10 and a load-bearing horizontal frame 20 mounted on the supporting vertical frame 10; the upper surface of the load-bearing horizontal frame 20 is used to carry materials 2 placed thereon; the load-bearing horizontal frame 20 is connected to a hanging rack 30 extending downward; the hanging rack 30 is used to carry materials 2 hanging below the load-bearing horizontal frame 20.

[0048] In this embodiment, the supporting vertical frame 10 is arranged along the height direction of the shelf 1. The supporting vertical frame 10 can support the bearing horizontal frame 20. The upper surface of each bearing horizontal frame 20 can bear materials, and the downward-extending hanging rack 30 can also bear materials. Therefore, each bearing horizontal frame 20 can bear two layers of materials, increasing the amount of materials stored in a single bearing horizontal frame 20. Furthermore, the upper and lower layers of materials are arranged opposite each other in the height direction, making full use of the space in the height direction of the shelf 1. This reduces the footprint of the shelf 1 when storing the same amount of materials 2, thus lowering warehousing costs.

[0049] In addition, compared to simply stacking materials, hanging materials on the rack 30 makes it more convenient to pick up and put down materials.

[0050] When there are multiple layers of load-bearing horizontal frames 20 and multiple support vertical frames 10, the multiple layers of load-bearing horizontal frames 20 are spaced apart between two adjacent support vertical frames 10 along the height direction of the shelf 1. There can be multiple hanging racks, which are spaced apart.

[0051] It should be noted that, as Figures 1a to 3 As shown, Figure 3 for Figure 2 The exploded view of the shelf shown shows that there can be two or more support columns 10, for example, three, four, or five support columns 10. When there are two or more support columns 10, the multiple support columns 10 are arranged side by side at intervals in the horizontal direction, which can further increase the load-bearing space of the shelf 1. The load-bearing horizontal columns 20 on the same layer can carry different materials 2 or the same material 2.

[0052] In some embodiments of this application, such as Figures 1a to 3 As shown, the supporting crossbeam 20 includes: two connecting crossbeams 21 and multiple supporting longitudinal beams 22 for supporting materials 2; the two connecting crossbeams 21 are fixedly connected between two supporting vertical frames 10; the multiple supporting longitudinal beams 22 are spaced apart between the two connecting crossbeams 21 and are perpendicular to the two connecting crossbeams 21.

[0053] In this embodiment, multiple load-bearing longitudinal beams are spaced apart between two connecting crossbeams 21, and the upper surface of the load-bearing longitudinal beams supports the materials. Compared with a plate-shaped load-bearing layer, the spaced arrangement of multiple load-bearing longitudinal beams can reduce the weight of the load-bearing crossbeams 20, save costs, and also facilitate ventilation of the shelf 1.

[0054] Specifically, the connection between the load-bearing longitudinal beam and the connecting transverse beam 21 can be welding, snap-fitting, or threaded connection.

[0055] More specifically, such as Figures 1a to 3 As shown, the support frame 10 can be placed on the ground and includes two support columns 11 and a reinforcing beam 12 located between the two support columns 11. The reinforcing beam 12 and the support columns 11 form a triangle, making the shelf more stable.

[0056] like Figure 3 and Figure 4 As shown, Figure 4 for Figure 2 The diagram shows an isometric view of a load-bearing crossbeam in the shelving system. Each connecting beam 21 is connected to a supporting column 11 via a first connecting part 212. The connection between the first connecting part 212 and the supporting column 11 can be welding, snap-fit, or threaded. The connection between the connecting beam 21 and the first connecting part 212 can be welding or threaded. Figure 4As shown, the first connecting part 212 includes mutually perpendicular crossbeam connecting plates 2120. The side of the crossbeam connecting plate 2120 is connected to the side of the supporting column 11 to ensure the stability of the load-bearing crossbeam 20.

[0057] like Figures 5 to 7a As shown, Figure 5 for Figure 2 Axonometric view of the first hanging bracket and connecting clamp in the shelf shown; Figure 6 for Figure 2 Axonometric view of the first hanging bracket and connecting plate in the shelf shown; Figure 7a for Figure 2 The image shows an axonometric view of the second hanging rack in the shelf. In some embodiments of this application, the hanging rack 30 is a hanging rack 30 with two right-angle bends, including: a hanging longitudinal beam and two oppositely arranged hanging vertical beams; the hanging longitudinal beam is fixedly connected to the first end of the two hanging vertical beams, and the second end of the two hanging vertical beams is used to be fixedly connected to two supporting crossbeams 20, and the hanging longitudinal beam is perpendicular to the two hanging vertical beams; the hanging longitudinal beam of the hanging rack 30 is used to support the material 2.

[0058] In this embodiment, the mounting longitudinal beam is connected to the connecting horizontal beam 21 of the supporting horizontal frame 20 via the mounting vertical beam, and the upper surface of the longitudinal beam of the hanging frame 30 is used to support the material. Specifically, the two ends of the material 2 overlap the upper surfaces of two adjacent mounting longitudinal beams to achieve the mounting of the material 2.

[0059] The hanging bracket under the load-bearing crossbeam 20 provided in this application embodiment can be in at least two different forms. The first hanging bracket 31 and the second hanging bracket 32 ​​are used as examples for detailed description below.

[0060] Specifically, in some embodiments of this application, such as Figure 1a , Figure 1b and Figure 5 As shown, the hanger 30 is the first hanger 31; the opposite side wall of the top of the material 2 has a hanger mating boss 202; the height of the first hanging vertical beam 311 of the first hanger 31 is greater than the thickness of the boss 202 and less than the height of the material 2; the hanger mating boss 202 of the material 2 is respectively hung on the first hanging longitudinal beam 312 of the two adjacent first hangers 31.

[0061] In the embodiments of this application, such as Figure 1a , Figure 1b and Figure 5 , Figure 6 As shown, a bracket engaging boss 202 is provided on the side wall of the top of material 2. The bracket engaging boss 202 protrudes from the side wall of material 2, and the lower surface of the bracket engaging boss 202 overlaps the upper surface of the first hanging vertical beam 312. Since the height of the first hanging vertical beam 311 is less than the height of material 2, the first hanging vertical beam 311 is shorter, which saves more manufacturing materials and is less prone to breakage.

[0062] It should be noted that, for materials 2 of different sizes and types, the hanging rack and the boss 202 can also be set on the side wall of the middle part of the material 2. Since the height of the first hanging vertical beam 311 of the first hanging rack 31 is greater than the height from the lower surface of the boss to the upper surface of the material 2, the first hanging rack 31 in the shelf 1 provided in this application embodiment can adapt to a variety of materials 2 of different sizes and is more universal.

[0063] In addition, the sidewall of material 2 can be recessed inward to form a groove so that the groove can cooperate with the longitudinal beam of the first hanger 31.

[0064] Specifically, the connection between the first mounting longitudinal beam 312 and the first mounting vertical beam 311 can be a threaded connection, welding, or snap-fit; it can also be connected by a connecting block 313.

[0065] In some embodiments of this application, such as Figure 1a ,and Figure 7a , Figure 7b , Figure 7c , Figure 7d , Figure 7e As shown, Figure 7a for Figure 2 Axonometric view of the first type of second hanging rack in the shelf shown; Figure 7b for Figure 7a The first type of second rack and the material are shown in the side view. Figure 7c This is an axonometric view of the second type of second hanger in the embodiments of this application; Figure 7d for Figure 7c The second type of second rack and the material are shown in the side view. Figure 7e This is a side view of the second type of second hanger, the hanger beam, and the material in the embodiment of this application; the hanger is the second hanger 32; the height of the second hanging vertical beam 321 of the second hanger 32 is greater than the height of the material 2; the second hanging longitudinal beam 322 of the second hanger 32 has a load-bearing part; the load-bearing parts 32210 of two adjacent hangers can jointly bear the material.

[0066] Specifically, such as Figure 1a , Figure 7a As shown, the second mounting longitudinal beam 322 includes: a base plate 3221 and a vertical plate 3222 perpendicular to the base plate 3221. The base plate 3221 extends out of both sides of the vertical plate 3222 to form two load-bearing parts 32210.

[0067] like Figure 1a and Figure 7aAs shown, since the height of the second hanging vertical beam 321 of the second hanger 32 is greater than the height of the material 2, the side wall of the material 2 does not need to be equipped with a hanging bracket boss 202, and the appearance requirements of the material 2 are not high. Material 2 of any shape can be hung on the supporting part of the base plate 3221. The base plate 3221 is perpendicular to the vertical plate 3222, so that the longitudinal section of the base plate 3221 and the vertical plate 3222 forms an inverted T-shape, and the vertical plate 3222 can limit the movement of the material 2. The two supporting parts on both sides of the same base plate 3221 support two different materials 2 respectively, and the supporting parts of two adjacent base plates 3221 share the same material 2.

[0068] In other embodiments, the second mounting longitudinal beam 322 of the second bracket 32 ​​may only have a base plate 3221, without the need for a vertical plate 3222. There are two specific implementation methods, such as... Figure 7c and Figure 7d As shown, when there are multiple second hangers 32, they are grouped into two groups, and the distance between the two second hangers in each group is less than the width of the bottom of the material box. The distance between the two closest second hangers in two adjacent groups is greater than the width of the bottom of the material box. The upper surface of the bottom plate 3221 of the two second hangers 32 is used to support the material, so that the second hanger can support the bottom of the material box near the middle position.

[0069] In other embodiments, in Figure 7d Based on this, a bracket crossbeam 324 can be added between two adjacent second brackets, such as... Figure 7e As shown, two second hangers are grouped together, and the bottoms of the two second hangers in each group are connected by a hanger beam 324. The distance between the two second hangers in each group is less than the width of the bottom of the material box. The distance between the two closest second hangers in two adjacent groups is greater than the width of the bottom of the material box. Specifically, the bottom of the material box may be provided with a groove that cooperates with the hanger beam 324 to improve the stability of the material box.

[0070] It should be noted that the first rack 31 and the second rack 32 can be installed on the same layer of the load-bearing horizontal frame 20, or on different layers of the load-bearing horizontal frame 20. In a single shelf 1, either the first rack 31 or the second rack 32 can be used exclusively. There are no restrictions here.

[0071] Specifically, such as Figure 7a As shown, the second bracket 32 ​​also includes a first reinforcing rib 323, the two ends of which are connected to the second hanging vertical beam 321 and the second hanging longitudinal beam 322 respectively, which serves to strengthen the structure.

[0072] In some embodiments of this application, such as Figure 2 , Figures 5 to 7aAs shown, the second end of the hanging vertical beam of the bracket 30 is fixedly connected to the bearing crossbeam 20 by a connecting plate 41 clamped on the bearing crossbeam 20; or, it is fixedly connected to the bearing crossbeam 20 by a connecting plate 42 at the bottom of the bearing crossbeam 20.

[0073] In the embodiments of this application, such as Figure 2 , Figures 5 to 7a As shown, connecting clamp 41 and connecting plate 42 can be mounted on the connecting beam 21 of the supporting crossbeam 20. The second end of the hanging bracket vertical beam is fixedly connected to the supporting crossbeam 20 via the connecting clamp 41 of the connecting beam 21. The connecting clamp 41 includes a first sub-clamp 411 and two second sub-clamps 412 perpendicular to the first sub-clamp 411. The second sub-clamps 412 are arranged vertically and are located at both ends of the first sub-clamp 411. The connecting beam 21 is located within the accommodating space formed by the first sub-clamp 411 and the two second sub-clamps 412. Because the contact surface between the connecting clamp 41 and the connecting beam 21 is large, the connection between the hanging bracket vertical beam and the connecting beam 21 is more stable and secure. Figure 2 , Figure 6 As shown, the second end of the hanging bracket vertical beam can also be fixedly connected to the connecting beam 21 via the connecting plate 42 of the connecting beam 21. The connecting plate 42 is a third connecting plate 42, which is perpendicular to the number of hanging brackets. The upper surface of the third connecting plate 42 is connected to the connecting beam 21, and the lower surface is connected to the hanging vertical beam.

[0074] Specifically, the connection between the connecting clamp 41 and the connecting crossbeam 21, and between the connecting plate 42 and the connecting crossbeam 21, can be welding, threaded connection, or riveting. The connection between the connecting clamp 41 and the hanging vertical beam, and between the connecting plate 42 and the hanging vertical beam, can be welding, threaded connection, or riveting.

[0075] In some embodiments of this application, two connecting crossbeams 21 are provided with a plurality of connecting slots 211, and the bearing longitudinal beam is a first bearing longitudinal beam 221. The two ends of the first bearing longitudinal beam 221 are respectively connected between the two connecting crossbeams 21 through the connecting slots 211.

[0076] In the embodiments of this application, such as Figure 4As shown, the connecting crossbeam 21 is provided with multiple connecting slots 211, and both ends of the first supporting longitudinal beam 221 are connected to the connecting crossbeam 21 through the connecting slots 211. Therefore, the spacing between the first supporting longitudinal beams 221 can be adjusted by connecting both ends of the first supporting longitudinal beams 221 to the connecting slots 211 at different positions. For example, when the material 2 is small, the spacing between the first supporting longitudinal beams 221 can be adjusted to be smaller to prevent the material 2 from falling from adjacent first supporting longitudinal beams 221. When the material 2 is large, the spacing between the first supporting longitudinal beams 221 can be adjusted to be larger, the number of first supporting longitudinal beams 221 can be reduced, and the weight of the supporting crossbeam 20 can be reduced.

[0077] Specifically, such as Figure 4 , Figure 8 As shown, Figure 8 for Figure 2 The first load-bearing longitudinal beam in the shelf shown is shown on the axle side. Both ends of the first load-bearing longitudinal beam 221 have snap-fit ​​parts 2211 extending outward, and the snap-fit ​​parts 2211 can be placed in the connecting slots 211.

[0078] In some embodiments of this application, such as Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, Figure 9 for Figure 2 The image shows an axonometric view of another type of load-bearing crossbar of the shelving unit. Figure 10 for Figure 2 The image shows another type of load-bearing crossbeam of the shelving unit. Figure 11 for Figure 2 The image shows an axonometric view of a second load-bearing longitudinal beam in the shelving unit; two connecting beams 21 are provided with multiple connecting slots 211, and the load-bearing longitudinal beam is a second load-bearing longitudinal beam 222. The second load-bearing longitudinal beam 222 includes a side 2221 and a bottom 2222. The side 2221 is perpendicular to the bottom 2, and at least a portion of the material 2 overlaps in the area enclosed by the side 2221 and the bottom 2.

[0079] In the embodiments of this application, such as Figure 4 , Figures 9 to 12 As shown, Figure 12 for Figure 2 The diagram shows an axonometric view of another type of second-bearing longitudinal beam in the shelving system. The connecting beam 21 has multiple connecting slots 211, and both ends of the second-bearing longitudinal beam 222 are connected to the connecting beam 21 via these slots. Therefore, the spacing between the second-bearing longitudinal beams 222 can be adjusted by connecting both ends of the second-bearing longitudinal beam 222 to the connecting slots 211 at different positions. The side 2221 can guide and limit the movement of the material 2, preventing it from shifting during movement.

[0080] It should be noted that each second load-bearing longitudinal beam 222 can only support one material 2, or it can support two materials 2; for example Figure 1a , Figure 10 and Figure 11 As shown, when carrying a material 2, the side edge 2221 is located at one end of the bottom edge 2222, so that the side edge 2221 and the bottom edge 2222 form an L-shape, and the two ends of the material 2 respectively overlap the bottom edge 2222 of the L-shaped second supporting longitudinal beam 222 with opposite openings; as Figure 1a , Figure 9 and Figure 12 As shown, when carrying two materials, the side 2221 is located in the middle of the bottom 2222, and the side 2221 and the bottom 2222 form an inverted T-shape. The same second bearing longitudinal beam 222 can carry different materials 2 through the bottom edges 2222 on both sides of the side 2221.

[0081] In some embodiments of this application, such as Figure 1a , Figure 2 and Figure 13 As shown, Figure 13 for Figure 2 The diagram shows an axonometric view of the support frame in the shelving unit. Shelving unit 1 also includes: a plurality of support frames 50 spaced apart on the load-bearing crossbeam 20; the height of each support frame 50 is greater than the height of the material; the bottom of each support frame 50 is fixedly connected to the load-bearing crossbeam 20, and the top of the support frame 50 is used to support the material 2. Specifically, the tops of two adjacent support frames 50 can jointly support one material 2.

[0082] In the embodiments of this application, such as Figure 1a , Figure 2 and Figure 13 As shown, the support frame 50 is mounted on the load-bearing crossbeam 20. The upper surface of the support frame 50 can be used to support materials without the need for a separate connecting beam 21. In other words, three layers of materials 2 can be supported on the same load-bearing crossbeam 20: supported by the upper surface of the load-bearing crossbeam 20, supported by the hanging bracket 30, and supported by the support frame 50 mounted on the load-bearing crossbeam 20. This further increases the load capacity of materials 2 and reduces the weight of the shelf 1.

[0083] In some embodiments of this application, such as Figure 1a , Figure 2 and Figure 13 As shown, the support frame 50 includes a rectangular connecting frame 51 and a support plate 52 perpendicular to the rectangular connecting frame 51. The support plate 52 is located on the top of the rectangular connecting frame 51. The bottom of the rectangular connecting frame 51 is fixedly connected to the bearing crossbeam 20. The height of the rectangular connecting frame 51 is greater than the height of the material 2. Two adjacent support frames 50 support one material 2.

[0084] In the embodiments of this application, such as Figure 1a , Figure 2 and Figure 13 As shown, the rectangular connecting frame 51 can support the material 2 to a certain height, so that there is a bearing space between the material 2 supported by the support frame 50 and the bearing crossbeam 20, which is used to accommodate the material supported on the upper surface of the bearing crossbeam 20. The support frame 50 is perpendicular to the rectangular connecting frame 51. The rectangular connecting frame 51 includes two supporting vertical beams 511 and two supporting longitudinal beams 512. One end of the two supporting vertical beams 511 is connected to the connecting crossbeam 21 of the bearing crossbeam 20, specifically through a connecting clamp 41. The two supporting longitudinal beams 512 are located between the two supporting vertical beams 511. The support plate 52 and the top supporting longitudinal beam 512 form a cross shape. The part of the supporting longitudinal beam 512 that extends beyond the support plate 52 can limit the material 2. The material 2 overlaps the bearing part of the support plate 52 that extends beyond the supporting longitudinal beam 512.

[0085] Specifically, such as Figure 13 As shown, the support frame 50 also includes a second reinforcing rib 523. The two sections of the second reinforcing rib 523 are connected to the support vertical beam 511 and the support longitudinal beam 512 respectively, which serves to strengthen the structure.

[0086] It should be noted that, in this embodiment of the application, a single load-bearing crossbar 20 can support two layers of materials 2 using a support frame 50 and / or a hanging rack 30. In a shelf, it is possible to... Figure 1a As shown, it includes both the hanging rack 30 and the support frame 50. In practical applications, a shelf may be equipped with only the hanging rack 30 or only the support frame. The specific configuration can be determined according to actual needs, and this application does not impose any restrictions.

[0087] In some embodiments of this application, the hanger 30 includes a support portion that matches the top or bottom contour of the material. This support portion is connected to the support crossbeam 20 via an adjustable connector. The adjustable connector allows adjustment of the height between the support portion and the support crossbeam 20. In this embodiment, by providing an adjustable connector, the position of the support portion in the height direction can be adjusted according to the size of the material box, making the hanger 30 more versatile. Specifically, the adjustable connector can be a telescopic rod.

[0088] An embodiment of the second aspect of this application provides a support frame for a shelf, the support frame being connected to a plurality of downwardly extending hangers 30; the plurality of hangers 30 are used to support materials 2 suspended below the support frame 20.

[0089] In this embodiment, the upper surface of each layer of support frame 20 can bear materials, and the downward-extending hanging rack 30 can also bear materials. Therefore, each layer of support frame 20 can bear two layers of materials, increasing the amount of materials stored in a single layer of support frame 20. Furthermore, the upper and lower layers of materials are arranged opposite each other in the height direction, making full use of the space in the height direction of the support frame 20, reducing the footprint of the support frame 20 when storing the same amount of materials 2, and reducing warehousing costs.

[0090] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
