Description

Technical Field

[0001] This utility model relates to the field of exchange boxes, and in particular to an exchange box and a packaging structure for the exchange box. Background Technology

[0002] With the rapid development of the transportation industry, multimodal transport, as an efficient and environmentally friendly mode of transportation, is receiving increasing attention. However, the modular connection and packaging of containerized products for shipment remains a challenge in multimodal transport.

[0003] Currently, the maximum length of a standard ocean shipping container is 45 feet, while the maximum length of containers transported by the China-Europe Railway Express is 40 feet. However, the transportation costs for non-standard containers are significantly higher than those for standard containers, and they are subject to various legal and regulatory constraints. Therefore, in transoceanic operations, packing products into standard containers is undoubtedly a more cost-effective and better-protected solution compared to shipping products by full truckload or full container load.

[0004] However, because the container itself occupies a certain amount of space, mainstream products such as 45ft rail-road intermodal side curtain exchange containers cannot be directly loaded into containers of the same or similar length, making it difficult to achieve cost-optimized transportation solutions for mainstream products such as 45ft rail-road intermodal side curtain exchange containers. Utility Model Content

[0005] One objective of this invention is to propose an exchange container that, through its structural design, can be easily installed into containers of the same or similar length while ensuring its own strength and adaptability to working conditions, thereby achieving optimized transportation costs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] One aspect of this utility model provides a switching enclosure, which is an assembly formed by components. The assembled switching enclosure has at least a front wall portion and a floor portion. The components include a front wall module and a floor module. The front wall module includes a front wall portion for constructing the front wall portion and a floor portion disposed on the front wall portion. A connecting structure is provided between the floor module and the floor portion for connecting the floor module and the floor portion. When the floor portion and the floor module are connected through the connecting structure, the floor module extends rearward from the floor portion, so that the floor portion and the floor module together construct the floor portion.

[0008] According to some technical solutions of this application, the connection structure includes one or more combinations of screw connection structure, riveting structure, rivet connection structure, adhesive structure, and welding structure.

[0009] According to some technical solutions of this application, a positioning structure is also provided between the floor module and the floor portion.

[0010] According to some technical solutions of this application, the floor portion includes a rear end plate, the floor module includes a front end plate, the positioning structure includes a positioning pin and a positioning hole, one of the positioning pin and the positioning hole is disposed on the rear end plate, and the other is disposed on the front end plate. When the rear end plate and the front end plate are abutted together, the positioning pin extends into the positioning hole.

[0011] According to some technical solutions of this application, the relative surfaces of the front end plate and the rear end plate are mutually adapted planes, arcs, slopes or stepped surfaces.

[0012] According to some technical solutions of this application, the rear end plate of the floor section and the front end plate of the floor module are connected through the connection structure.

[0013] According to some technical solutions of this application, the front wall includes a wall panel and two columns disposed at both ends of the wall panel. One end of the column is connected to the side of the wall panel, and the other end of the column is bent backward relative to the wall panel. The floor is disposed at the bottom of the wall panel and extends backward relative to the wall panel. The floor is located between the two backward-bent portions of the columns.

[0014] According to some technical solutions of this application, the rear end of the floor section is flush with the rear end of the column, and the front end of the floor module is wider than the rear end of the floor section. When the floor section is connected to the floor module, the front end of the floor module simultaneously abuts against the floor section and the column.

[0015] According to some technical solutions of this application, the floor module includes two crossbeams and multiple plates. The two crossbeams are spaced apart. The connection structure is configured to connect the floor portion to one end of the two crossbeams along the length direction. The multiple plates are arranged along the length direction of the crossbeams and are respectively connected to the two crossbeams.

[0016] Another aspect of the technical solution of this application provides a packaging structure for an exchange container, comprising: the exchange container described in any of the above technical solutions: a container, wherein the front wall module and the floor module of the exchange container are distributed inside the container in a detached state, wherein the floor module is arranged along the length direction of the container.

[0017] In this application, the structure used to construct the floor portion is divided into at least two parts, namely, at least a floor section and a floor module. For the floor module, it is ensured that the length of the floor module is less than the total length of the exchange container. Correspondingly, it is ensured that the length of the floor module is less than the total internal length of a standard container of the same specifications as the exchange container. Thus, when the exchange container is packed into a standard container of the same specifications, the floor module can be easily packed into the standard container by separating the floor section and the floor module. As for the floor section, the floor section is incorporated into the front wall module. The packing of the front wall module will not occupy much length space inside the container, which can also meet the packing requirements of the standard container, thereby reducing the cost of the packing and transportation scheme for the exchange container. In addition, the floor section can be used to strengthen the structure and stability of the front wall module, while also avoiding the problem of poor stress caused by the rear section of the exchange container.

[0018] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention. Attached Figure Description

[0037] Although the present invention can be readily embodied in various forms of implementation, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is also understood that this specification should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0038] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0039] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, etc.) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0040] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make the description of the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0041] Some embodiments of this utility model propose an exchange box and a packaging structure for the exchange box.

[0042] like Figures 1 to 5 As shown, the switching enclosure is an assembly formed by combining components, and the assembled switching enclosure has at least a front wall portion (which can be specifically understood as...). Figures 1 to 5 The front wall section shown) and the floor section (specifically, can be understood as...) Figures 1 to 5 The floor section 12 and floor module 20 are shown in the diagram.

[0043] For example, the front wall portion of the exchange box can be understood as a component of the exchange box used at one end of the vehicle body near the front of the skeleton vehicle.

[0044] Of course, it is understood that the switching enclosure is not limited to only including the front wall and floor. In other embodiments, the switching enclosure may also include the rear wall or rear door module, and / or the top frame module, and / or the side panel module, etc. Those skilled in the art can configure the specific components of the switching enclosure according to their needs, which will not be elaborated further here.

[0045] The components used to assemble the exchange box include a front wall module 10 and a floor module 20. The front wall module 10 includes a front wall portion for constructing the front wall and a floor portion 12 disposed on the front wall portion. A connecting structure is provided between the floor module 20 and the floor portion 12 for connecting the floor module 20 and the floor portion 12. When the floor portion 12 and the floor module 20 are connected by the connecting structure, the floor module 20 extends rearward from the floor portion 12, so that the floor portion 12 and the floor module 20 together construct the floor portion.

[0046] The structure used to construct the floor portion is divided into at least two parts, namely, at least the floor portion 12 and the floor module 20, as exemplified in the embodiment. For the floor module 20, it can be ensured that the length of the floor module 20 is less than the total length of the exchange container. In this way, even if the total length of the floor portion of the exchange container is the same as or similar to the total length of a standard container of the same specifications, it can be ensured that the length of the floor module 20 is always less than the total length of the standard container. Thus, when the exchange container is packed into a standard container of the same specifications, by separating the floor portion 12 and the floor module 20, the floor module 20 can be easily packed into the standard container without the problem that the floor module 20 exceeds the total length of the standard container and cannot be packed. As for the floor section 12, since the floor section 12 is incorporated into the front wall module 10, it is understood that the packaging of the front wall module 10 will not occupy the length space inside the container. Therefore, incorporating the floor section 12 into the front wall module 10 will not affect the length space inside the standard container, thereby meeting the packaging requirements of the standard container, realizing the cost reduction of the exchange container packaging and transportation scheme, better compatibility with the low-transportation-cost optional scheme, and reducing product costs and modification difficulty.

[0047] Furthermore, by connecting the floor section 12 to the front wall section, compared to the traditional front wall section without the floor section 12, the structure and stability of the front wall module 10 can be strengthened, enabling it to more reliably withstand various external impacts during transportation and ensuring the safety of goods.

[0048] Furthermore, by integrating the floor section 12 into the front wall module 10, the split point of the floor section (i.e., the connection point between the floor section 12 and the floor module 20) is relatively close to the front wall, thus avoiding the problem of poor stress distribution caused by the rear segmentation of the exchange box. Specifically, considering that when loading and unloading goods from the rear of the exchange box, forklifts will enter and exit from the rear of the exchange box, resulting in a maximum axle load that may even exceed 7.2t, this embodiment integrates the floor section 12 into the front wall module 10, making the segmentation point of the floor section relatively close to the front wall module 10. Therefore, it effectively avoids the problems of unreasonable load-bearing structure and poor rear stress distribution that may exist due to the rear segmentation of the exchange box, achieving better adaptability to working conditions, making the product more reliable and stable under harsh working conditions, and ensuring the safe transportation of goods. In addition, the exchange box structure of this embodiment also improves the lightweight potential of the exchange box, reduces the product's weight, lowers transportation costs, and meets the requirements of energy conservation and environmental protection.

[0049] For example, a positioning structure is also provided between the floor module 20 and the floor section 12. The positioning structure facilitates on-site assembly and positioning of the floor module 20 and the floor section 12, reducing the need for special tooling and measurement work for on-site assembly, and improving on-site assembly accuracy and efficiency.

[0050] For specific examples, in conjunction with the appendix Figure 6 and Figure 9 It is understood that the floor section 12 has a rear end plate 121; combined with the attached Figure 10 It can be understood that the floor module 20 includes two crossbeams 22 and multiple panels 23. The two crossbeams 22 are arranged at intervals along the left-right direction, and the multiple panels 23 are laid flat along the length of the crossbeams 22 and connected to the two crossbeams 22 respectively. The support surface constructed by the panels 23 is used to support the goods inside the exchange container. For example, Figure 11 As shown, each crossbeam 22 has a front end plate 21 at one end.

[0051] The positioning structure includes a positioning pin 1212 and a positioning hole 212. One of the positioning pin 1212 and the positioning hole 212 is set on the rear end plate 121, and the other is set on the front end plate 21. When the rear end plate 121 and the front end plate 21 are close together, the positioning pin 1212 extends into the positioning hole 212, thereby realizing the rapid positioning of the floor module 20 and the floor part 12. It has the advantages of simple structure and convenient positioning construction.

[0052] Optionally, the positioning pin 1212 can be specifically set as a cylindrical pin, and the positioning hole 212 can be set as an oblong hole. In this way, the positioning pin 1212 can have a certain amount of displacement within the positioning hole 212, which can achieve a small adjustment of the position of the floor module 20 and the floor part 12 to a certain extent, thereby being compatible with the different structural precision of the floor module 20 and the floor part 12.

[0053] Of course, in other embodiments, the positioning pin 1212 can also be selected in other shapes, such as an elliptical cylinder, a square cylinder, a semi-cylinder, etc., and the shape and size of the positioning hole 212 roughly match the positioning pin 1212.

[0054] Optionally, the positioning structure is not limited to positioning pins and positioning holes. In other embodiments, positioning marks or grooves can be set on the front wall module or floor module for positioning by manual or mechanical means to reduce costs. Furthermore, even when using positioning pins for positioning, advanced positioning technologies such as laser positioning and sensor positioning can be employed to improve positioning accuracy and efficiency.

[0055] Optionally, the rear end plate 121 of the floor section 12 is connected to the front end plate 21 of the floor module 20 via a connecting structure. Taking a screw connection structure as an example, the rear end plate 121 of the floor section 12 is provided with a first through hole 1211, and the front end plate 21 of the floor module 20 is provided with a second through hole 211. The first through hole 1211 and the second through hole 211 correspond to each other. Screws are used to pass through the first through hole 1211 and the second through hole 211 to fasten the front end plate 21 and the rear end plate 121 together. A positioning structure, such as a positioning pin 1212 and a positioning hole 212, is used. When the positioning pin 1212 extends into the positioning hole 212, the front end plate 21 and the rear end plate can be positioned so that the first through hole 1211 and the second through hole 211 correspond one-to-one, thereby facilitating product assembly.

[0056] Optionally, the front end plate 21 of each crossbeam 22 may be attached as follows. Figure 11 As shown, eight second through holes 211 are provided at both ends of the rear end plate 121 of the floor portion 12, as shown in the attached diagram. Figure 9 As shown, each end is provided with eight first through holes 1211, which are respectively fixed with eight screws, making the connection between the floor module 20 and the floor part 12 more reliable. Of course, the number of first through holes 1211 and second through holes 211 at each corresponding position of the front end plate 21 and the rear end plate 121 is not limited to the eight listed. In other embodiments, the number of first through holes 1211 and second through holes 211 at each corresponding position of the front end plate 21 and the rear end plate 121 can be adjusted according to specific needs, such as four, six, ten, etc., which will not be listed here.

[0057] It is understood that the specific form of the connection structure is not limited to the screw connection structure exemplified in this embodiment. In other embodiments, the connection structure can also be set as one of the following: riveting structure, rivet connection structure (such as Huck connection structure), adhesive structure, or welding structure; or, a combination of multiple of these structures. This allows for the selection of appropriate connection methods according to different needs and scenarios, improving the adaptability and versatility of the product. When multiple connection methods are used in combination, the connection strength and reliability of the product can be further enhanced.

[0058] Optionally, combined Figure 9 and Figure 11 It is understandable that the opposing surfaces of the front-end board 21 and the rear-end board 121 are mutually compatible planes.

[0059] Of course, in other embodiments, the opposing surfaces of the front end plate 21 and the rear end plate 121 can also be configured as curved surfaces, inclined surfaces, or stepped surfaces, etc., and are not limited to the plane shown in the accompanying drawings. Different contact surface styles can meet different structural and functional requirements, expanding the design space of the product. Furthermore, the design of the contact surface can be optimized according to actual conditions to improve the performance and stability of the product.

[0060] Different contact surface styles can meet different structural and functional requirements, expanding the design space of the product. Furthermore, the design of the contact surface can be optimized according to actual conditions, improving the product's performance and stability.

[0061] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the front wall includes a wall panel 111 and two columns 112 disposed at both ends of the wall panel 111. One end of each column 112 is connected to the side of the wall panel 111, and the other end of each column 112 is bent backward relative to the wall panel 111 to form a rearward bend 1121. The floor portion 12 is disposed at the bottom of the wall panel 111 and extends backward relative to the wall panel 111. The floor portion is located between the rearward bends of the two columns 112. In this way, the floor portion 12 can support the columns 112 outward on both sides, making the wall panel 111 less prone to bending and deformation, and further improving the structural strength and stability of the front wall.

[0062] Optionally, combined Figure 1 and Figure 2 It is understood that the rear end of the floor section 12 is flush with the rear end of the column 112, and the front end of the floor module 20 is wider than the rear end of the floor section 12. When the floor section 12 and the floor module 20 are connected, the front end of the floor module 20 simultaneously abuts against both the floor section 12 and the column. In this way, the structural rigidity of the column is further strengthened, thereby improving the overall structural strength and stability of the front wall module 10 and extending the product's lifespan.

[0063] More specifically, the front wall panel 111 is typically made of materials such as steel or aluminum alloy to provide sufficient strength and stability. Specifically, the front wall panel 111 mainly comprises three panels: a front panel 1112, a back panel, and two side panels. The front panel 1112 is a vertical planar structure used to prevent goods from moving forward and to withstand pressure from the front. A floor section 12 is formed at the bottom of the front panel 1112. Near the two side edges of the floor section 12, two protruding positioning pins 1212 are respectively provided. These two positioning pins 1212 cooperate with corresponding positioning holes 212 on the floor module 20 to initially position the relative positions of the front wall module 10 and the floor module 20 during assembly, ensuring that the floor section 12 at the bottom of the front wall module 10 can accurately contact the front end of the floor module 20. The back panel is arranged parallel to the front panel 1112 to enhance the overall structural strength of the front wall module 10. The back panel can specifically be a transverse corrugated plate 1111. Two side panels connect to the front panel 1112 and the back panel on both sides, forming a closed frame structure, which further improves the stability of the front wall module 10. Columns are located at the corners where the side panels connect to the front panel 1112 and the back panel, to enhance the overall structural strength and stability of the front wall module 10, and to provide a positioning reference for assembly with the floor module 20.

[0064] The floor module 20 is typically made of thick wooden planks or high-strength composite materials with high load-bearing capacity. A small portion of the front end of the floor module is incorporated into the front wall module 10. This design allows the floor module 20 to be shorter than the internal length of a standard shipping container, enabling it to be loaded into the container. The surface of the floor module 20 usually has an anti-slip treatment to ensure that goods do not slip during transport. The floor module 20 has two positioning holes 212 near the two side edges at the front end. These holes 212 engage with positioning pins 1212 on the bottom floor section 12 of the front panel 1112 to initially position the front wall module 10 and the floor module 20 relative to each other during assembly.

[0065] For the assembly of floor module 20 and floor section 12, positioning pin 1212 is fixed to the floor section 12 of front wall module 10 to assist in positioning between front wall module 10 and floor module 20. During assembly, positioning pin 1212 is inserted into the corresponding hole on floor module 20 to ensure that floor section 12 and floor module 20 are initially aligned.

[0066] Bolts secure the front wall module 10 to the floor module 20. During tightening, a diagonal tightening method can be used to improve connection stability. To further enhance the connection strength between modules, gaskets or sealant can be added to the contact surfaces to improve sealing performance and prevent dust, moisture, etc., from entering the module interior.

[0067] In practical applications, the specific structure and matching method of the front wall module 10 and the floor module 20 can be adjusted and optimized according to different needs to ensure the performance and reliability of the road-rail intermodal transport side curtain exchange box.

[0068] The working process is as follows: For assembly, positioning pins 1212 are fixed to the front wall module 10 to assist in positioning the front wall module 10 and the floor module 20. Then, bolts are used to completely fix the front wall module 10 to the floor module 20, achieving the desired effect. Figure 1 As shown. For packaging, the front wall module 10, floor module 20, and bolt connection module are all packaged and secured separately. Among them, the positioning pin 1212 can be fixed to the front wall module 10 or packaged separately.

[0069] When connecting the front wall module 10 and the floor module 20, first insert the locating pins 1212 into the corresponding holes to ensure initial alignment of the two modules. Then, use bolts or other fasteners to tighten them, ensuring a secure and reliable connection. During tightening, a diagonal tightening method can be used to improve the stability of the connection.

[0070] For the installation of locating pin 1212, either a press-fit or threaded connection can be used. Press-fit installation is simple and quick, but may cause some damage to the surface of the module. Threaded connections are more secure, but the installation process is relatively more complex.

[0071] When selecting fasteners, bolts, nuts, etc., of different materials and specifications can be chosen according to actual needs and the operating environment. For example, stainless steel fasteners can be selected in corrosive environments; high-strength fasteners can be selected when the load needs to be large.

[0072] To further improve the fixing strength between modules, sealing gaskets or sealants can be added to the contact surfaces to enhance sealing performance and prevent dust, moisture, and other contaminants from entering the module.

[0073] During the packaging process, cushioning materials such as foam plastic and air cushion film can be used to pack the modules (such as front wall module 10, floor module 20, etc.) to prevent them from being bumped and damaged during transportation.

[0074] For containers of different sizes, the size and form of the modules can be reasonably adjusted according to the internal dimensions of the container and the dimensions of the product to ensure that the product can be loaded and transported smoothly.

[0075] During transportation, a fixing device can be used to secure the exchange container to the transport vehicle to prevent the exchange container from moving or shaking during the process.

[0076] Regularly inspect and maintain the modules to ensure that the connections are secure and undamaged. If any problems are found, repair or replace them promptly.

[0077] Some embodiments of this application provide a packing structure for an exchange container, which includes: the exchange container and a container as described in any of the above embodiments, wherein the front wall module 10 and the floor module 20 of the exchange container are distributed in the container in a detached state, wherein the floor module 20 is arranged along the length direction of the container, for example, when the floor module 20 is packed into the container, the length direction of the floor module 20 is approximately consistent with the length direction inside the container.

[0078] It is understood that, through the exchange container structure of this embodiment, products can be packaged into 45ft or 40ft containers, and other sizes of containers, such as 20ft containers or custom-made containers of special sizes, can be selected according to actual conditions.

[0079] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
