Description

Technical Field

[0001] This utility model relates to the field of transportation and storage equipment technology, specifically to a container. Background Technology

[0002] As an important piece of equipment for logistics and warehousing, containers are widely used in cargo transportation due to their advantages such as sufficient strength, reusability, convenient loading and unloading, space and load capacity.

[0003] However, traditional steel bulk cargo containers suffer from thin plates that are easily damaged by wear or corrosion, and maintenance costs are high. In particular, when loading mineral bulk cargo, the cargo causes significant wear to the anti-corrosion paint on the container walls (such as top panels, end panels, side panels, or door panels). Without anti-corrosion protection, the walls corrode extremely quickly under the combined action of moisture and minerals.

[0004] Therefore, a container is needed to at least partially solve the above problems. Utility Model Content

[0005] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] To at least partially solve the above problems, this utility model provides a container, the container including a frame, a top panel, side panels, end panels, and door panels, wherein at least one of the entire top panel, the entire side panel, the entire end panel, and the entire door panel includes at least two layers of structure:

[0007] A steel plate, which is fixedly connected to the frame; and

[0008] A composite material plate is located on at least one side of the steel plate, facing inwards and outwards from the box, and is fixedly connected to the steel plate.

[0009] The composite material plate has the same shape as the steel plate so as to be integrally bonded to the steel plate, or the composite material plate is flat and is partially bonded to the steel plate.

[0010] According to this utility model, at least one of the entire top panel, entire side panel, entire end panel, and entire door panel is configured with a two- or multi-layer structure, wherein the side of the steel plate facing inward and / or the side facing outward is a composite material panel. This design enables the container to meet long-term requirements for wear resistance, acid and alkali resistance, salt spray resistance, and mildew resistance. Furthermore, it saves on interior painting costs and labor, and reduces high repair costs due to damage to the top panel, side panel, end panel, or door panel. Placing the composite material panel on the side of the steel plate facing inward significantly reduces wear and corrosion of the container's inner wall by cargo (especially bulk cargo), increases the structural strength and rigidity of the wall panels, distributes stress, and prevents deformation and bulging in the middle of the side panel when loading small particle bulk cargo. Placing the composite material panel on the side of the steel plate facing outward reduces aging and corrosion of the outer wall and mitigates impacts to the outer wall, extending the container's service life.

[0011] Optionally, the composite material plate has the same shape as the steel plate, and the steel plate and the composite material plate of the side plate and the steel plate and the composite material plate of the end plate are corrugated plates.

[0012] Optionally, the corrugations of the steel plate and composite material plate of the side plate and the steel plate and composite material plate of the end plate are through corrugated.

[0013] Optionally, the composite material plate has the same shape as the steel plate.

[0014] The steel plate and the composite material plate of the top plate are non-corrugated plates; and / or

[0015] The steel plate and the composite material plate of the door panel are non-corrugated corrugated plates.

[0016] Optionally, the composite material plate has the same shape as the steel plate.

[0017] The steel plate and the composite material plate of the top plate are constructed as corrugated plates in the middle region and as flat plates in the peripheral region; and / or

[0018] The steel plate and the composite material plate of the door panel are constructed as a corrugated plate in the middle area and as a flat plate in the peripheral area.

[0019] Optionally, the steel plate is a single component or is assembled from multiple steel plates.

[0020] Optionally, the composite material plate is a single component or is assembled from multiple composite material plates.

[0021] Optionally, the composite material plate is fixedly connected to the steel plate by at least one of rivets, adhesives, and fixing brackets.

[0022] Optionally, the composite material plate and the steel plate are fixedly connected by at least rivets, wherein,

[0023] The rivet is a closed rivet; and / or

[0024] A rubber pad is provided between the rivet head and the steel plate or the composite material plate.

[0062] This utility model provides a container to improve its wear resistance, corrosion resistance, and other properties. The container is formed by a base frame, side walls, end walls, doors, and top walls, creating a storage space.

[0063] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0064] like Figure 1 and Figure 2As shown, the container includes a frame 50, which is the basic skeleton of the container. The frame 50 includes a base frame, uprights, crossbeams, side beams, and door frames. The container also includes side walls, end walls, doors, and a top wall. The side walls include side panels 20, which extend in the length direction D1 and height direction D3 of the container. The end walls include end panels 30, which extend in the width direction D2 and height direction D3 of the container. The top wall includes a top panel 10, which extends in the length direction D1 and width direction D2 of the container. The doors include door panels connected to the frame. The doors can be end doors or side doors. That is, the container includes a top panel 10, side panels 20, end panels 30, and door panels (not shown in the figure), which are all connected to the frame 50.

[0065] At least one of the entire top panel 10, the entire side panel 20, the entire end panel 30, and the entire door panel comprises at least two layers of structure, namely, one layer of steel plate and at least one layer of composite material panel. The composite material panel is located on at least one side of the steel plate facing inward and outward from the box. That is, the composite material panel substantially covers (but is not limited to being completely tightly attached to) the entire steel plate, and the steel plate covers (but is not limited to being completely tightly attached to) the entire composite material panel. It should be noted that, due to the need for connection with the frame 50, the dimensions of the composite material panel and the steel plate may differ slightly at the edges.

[0066] The steel plate is fixedly connected to the frame. The composite material plate is located on at least one side of the steel plate, facing inwards and outwards from the box, and is fixedly connected to the steel plate.

[0067] In the first preferred embodiment, the composite material plate has the same shape as the steel plate so as to be integrally bonded to the steel plate.

[0068] Specifically, such as Figure 3 As shown, the top plate 10 can be configured to include a steel plate 11 and a composite material plate 12. For example, the top plate 10 includes a steel plate 11 and a layer of composite material plate 12, the composite material plate 12 having the same shape as the steel plate 11 and being attached to the side of the steel plate 11 facing inwards. For example, the top plate 10 includes a steel plate 11 and a layer of composite material plate 12, the composite material plate 12 having the same shape as the steel plate 11 and being attached to the side of the steel plate 11 facing outwards. For example, the top plate 10 includes a steel plate 11 and two layers of composite material plate 12, the two layers of composite material plate 12 having the same shape as the steel plate 11 and being attached to the sides of the steel plate 11 facing inwards and outwards, respectively.

[0069] like Figure 4As shown, the side panel 20 can be configured to include a steel plate 21 and a composite material plate 22. For example, the side panel 20 includes a steel plate 21 and a layer of composite material plate 22, the composite material plate 22 having the same shape as the steel plate 21 and being attached to the side of the steel plate 21 facing inwards. For example, the side panel 20 includes a steel plate 21 and a layer of composite material plate 22, the composite material plate 22 having the same shape as the steel plate 21 and being attached to the side of the steel plate 21 facing outwards. For example, the side panel 20 includes a steel plate 21 and two layers of composite material plate 22, the two layers of composite material plate 22 having the same shape as the steel plate 21 and being attached to the sides of the steel plate 21 facing inwards and outwards, respectively.

[0070] Similarly, as Figure 5 As shown, the steel plate 31 and composite material plate 32 of the end plate 30 can also be configured as described in the foregoing example. The steel plate and composite material plate (not shown in the figure) of the door panel can also be configured as described in the foregoing example.

[0071] It should be noted that the composite material plate and the steel plate have the same shape to fit together as a whole, that is, the composite material plate and the steel plate are also the same size. The composite material plate basically overlaps the steel plate completely, but due to the need for connection with the frame 50, the size of the composite material plate and the steel plate may be slightly different at the edges.

[0072] According to this utility model, a composite material plate is laminated to the steel plates of the top, side, end, or door panels of the container, enabling the container to meet long-term requirements for wear resistance, acid and alkali resistance, salt spray resistance, and mildew resistance. Furthermore, it saves on interior painting costs and labor, and reduces high repair costs due to damage to the top, side, end, or door panels. Placing the composite material plate on the side of the steel plate facing inwards significantly reduces wear and corrosion of the container's inner walls by cargo (especially bulk cargo), increases the structural strength and rigidity of the wall panels, distributes stress, and prevents deformation and bulging in the middle of the side panels when loading small, loose cargo. Placing the composite material plate on the side of the steel plate facing outwards slows down aging and corrosion of the outer walls and reduces impacts, extending the container's service life. The composite material plate has the same shape as the steel plate and is integrally laminated, so it occupies almost no internal space. The composite material plate is lightweight, adding minimal weight to the container.

[0073] Optionally, the steel plate 21 and composite material plate 22 of the side plate 20 are corrugated plates. The corrugations of the steel plate 21 and composite material plate 22 of the side plate 20 are continuous corrugations. The steel plate 31 and composite material plate 32 of the end plate 30 are corrugated plates. The corrugations of the steel plate 31 and composite material plate 32 of the end plate 30 are continuous corrugations. Continuous corrugation means that the waveform is the same in the length or width direction of the steel plate 11 / 21 / 31 (or the composite material plate 12 / 22 / 32), in other words, the cross-section is the same in the length or width direction of the plate. The composite material plate of the continuous corrugated plate can be produced by pultrusion process.

[0074] Optionally, the steel plate 11 and composite material plate 12 of the top plate 10 are non-corrugated plates. For example, the steel plate 11 and composite material plate 12 of the top plate 10 are constructed as corrugated plates in the middle region and as flat plates in the peripheral region to facilitate connection with the frame 50.

[0075] Optionally, the steel plate and composite material plate of the door panel are non-corrugated sheets. For example, the steel plate and composite material plate of the door panel are constructed as corrugated sheets in the middle area and as flat sheets in the peripheral area to facilitate connection with the door frame. The non-corrugated composite material plate can be produced by a molding process.

[0076] The instruction manual is required. The corrugations of the corrugated plate are not limited to a sine wave shape. For example, the crests and troughs can be flat.

[0077] In the second preferred embodiment, such as Figures 11 to 16 As shown, the composite material sheet is flat and partially bonded to the steel sheet. For example, the composite material sheet is bonded to the steel sheet at the crests or troughs of the steel sheet. The flat composite material sheet is simple to process and manufacture.

[0078] The second preferred embodiment of this utility model is a variation of the first preferred embodiment. Except for the shape of the composite material panels, the container of the second preferred embodiment has a similar structure and / or construction to the container of the first preferred embodiment. The difference between the top plate 110 and the top plate 10 is only that the shape of the composite material panel 112 of the top plate 110 is different from that of the composite material panel 12 of the top plate 10. The difference between the side plate 120 and the side plate 20 is only that the shape of the composite material panel 122 of the side plate 120 is different from that of the composite material panel 22 of the side plate 20. The difference between the end plate 130 and the end plate 30 is only that the shape of the composite material panel 132 of the end plate 130 is different from that of the composite material panel 32 of the end plate 30.

[0079] Therefore, elements having substantially the same function as those in the first preferred embodiment will be numbered the same here, and for the sake of brevity, they will not be described in detail and / or illustrated.

[0080] In the two preferred embodiments described above, optionally, the steel plates of the top plate 10, side plate 20, end plate 30, or door panel are integral components or are spliced ​​from multiple steel plates. For example, the steel plate 11 of the top plate 10 is formed by welding multiple steel plates to form a corrugated plate.

[0081] Optionally, the composite material panels of the top plate 10, side plates 20, end plates 30, or door panels are integral components or are assembled from multiple composite material panels. For example, multiple composite material panels are bonded together with structural adhesive to form a composite material panel 12 with the same shape as the steel plate 11.

[0082] Regarding the method of fixing the composite material plate to the steel plate, the composite material plate can be fixedly connected to the steel plate by at least one of rivets, adhesive, and fixing brackets. For example, the composite material plate is fixedly connected to the steel plate at the contact point using at least one of rivets, adhesive, and fixing brackets.

[0083] The installation of composite material panels and steel plates is simple, and the riveting method facilitates replacement and maintenance after the composite material panels are worn out. The adhesive bonding method provides a better bond between the composite material panels and steel plates.

[0084] In other words, the composite material panel can be fixed to the steel plate using only multiple rivets, adhesive, or a fixing bracket. Alternatively, the composite material panel can be fixed to the steel plate using any two of the following methods: rivets, adhesive, or fixing brackets. Or, the composite material panel can be fixed to the steel plate using all three methods: rivets, adhesive, or fixing brackets. Alternatively, other methods can be used to fix the composite material panel and the steel plate together.

[0085] like Figure 2 , Figure 4 and Figure 5 As shown, the composite material plate is fixedly connected to the steel plate by multiple rivets 13. Specifically, the composite material plate 12 of the top plate 10 is fixedly connected to the steel plate 11 by multiple rivets 13. The composite material plate 22 of the side plate 20 is fixedly connected to the steel plate 21 by multiple rivets 13. The composite material plate 32 of the end plate 30 is fixedly connected to the steel plate 31 by multiple rivets 13.

[0086] Preferably, the rivet 13 is a closed-type rivet to ensure good sealing of the top plate 10, side plate 20, end plate 30, or door panel. More preferably, a rubber gasket 132 (e.g., ...) is provided between the rivet head 131 and the steel plate 11 / 21 / 31 or composite material plate 12 / 22 / 32. Figure 6 (as shown), to further enhance the sealing of the top plate 10, side plate 20, end plate 30 or door panel at the rivet 13 connection.

[0087] like Figures 7 to 10 as well as Figures 13 to 16As shown, the composite material panels are fixedly connected to the steel plates 11 / 21 / 31 by adhesive 14 (such as a high-strength structural adhesive). Specifically, adhesive 14 is applied between the steel plate 11 and the composite material panels 12 / 112 of the top plate 10 to fix the steel plate 11 and the composite material panels 12 / 112 together in a close fit. Adhesive 14 is applied between the steel plate 21 and the composite material panels 22 / 122 of the side plate 20 to fix the steel plate 21 and the composite material panels 22 / 122 together in a close fit. Adhesive 14 is applied between the steel plate 31 and the composite material panels 32 / 132 of the end plate 30 to fix the steel plate 31 and the composite material panels 32 / 132 together in a close fit.

[0088] Composite material panels are made from novel composite materials that possess characteristics such as high strength, wear resistance, corrosion resistance, light weight, and high plasticity. For example, composite material panels are made from any one of the following materials: glass fiber composites, carbon fiber composites, organic fiber composites, metal fiber composites, and ceramic fiber composites.

[0089] Of course, composite material plates can also be made from other new composite materials not mentioned in this article, which have the characteristics of high strength, wear resistance, corrosion resistance, light weight and high plasticity.

[0090] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the invention. Features described in one embodiment may be applied, alone or in combination with other features, to another embodiment, unless that feature is not applicable in that other embodiment or is otherwise stated.

[0091] This utility model has been described through the above embodiments. However, it should be understood that the above embodiments are only for illustrative purposes. This utility model is not limited to the above embodiments. Many variations and modifications can be made based on the teachings of this utility model, and all such variations and modifications fall within the scope of protection claimed by this utility model.
