Description

Technical Field

[0001] The invention relates to the field of exchange boxes, and in particular to an exchange box and a packaging structure of the exchange box. Background Art

[0002] With the rapid development of the transportation industry, road-rail transport has become more and more popular as an efficient and environmentally friendly mode of transportation. However, in the process of road-rail transport, the module connection and packaging of box-type products have always been a problem.

[0003] At present, the maximum length of a standard ocean container is 45ft, and the upper limit of the length of a container transported by the China-Europe Express is 40ft. However, the transportation cost of non-standard containers is much higher than that of standard containers, and there are various legal and regulatory restrictions. Therefore, in the transoceanic operation mode of products, compared with shipping products by truckload / full container, packing products in standard containers is undoubtedly a more cost-effective and better solution for product protection.

[0004] However, since the container structure itself takes up a certain amount of space, mainstream products such as the 45ft road-rail intermodal curtain side exchange box 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 the 45ft road-rail intermodal curtain side exchange box. Summary of the invention

[0005] One object of the present invention is to provide an exchange box, which, through its structural design, can be easily loaded into a container of the same or similar length while ensuring its own strength of use and adaptability to working conditions, so as to achieve optimized transportation costs.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The technical solution of one aspect of the present invention proposes an exchange box, which is a combination assembled by components, and the assembled exchange box has at least a front wall part and a floor part, wherein the components include a front wall module and a floor module, the front wall module includes a front wall part for constructing the front wall part and a floor part arranged on the front wall part, and a connecting structure for connecting the floor module and the floor part is arranged between the floor module and the floor part. When the floor part and the floor module are connected through the connecting structure, the floor module extends backward from the floor part, so that the floor part and the floor module jointly construct the floor part.

[0008] According to some technical solutions of the present application, the connection structure includes a combination of one or more of a screw connection structure, a riveted structure, a pull rivet connection structure, an adhesive structure, and a welding structure.

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

[0010] According to some technical solutions of the present 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 arranged on the rear end plate, and the other is arranged on the front end plate, and 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 the present application, the relative surfaces of the front end plate and the rear end plate are plane surfaces or curved surfaces or inclined surfaces or stepped surfaces that are adapted to each other.

[0012] According to some technical solutions of the present application, the rear end plate of the floor portion is connected to the front end plate of the floor module via the connecting structure.

[0013] According to some technical solutions of the present application, the front wall portion includes a wall panel and two columns arranged 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 portion is arranged at the bottom of the wall panel and extends backward relative to the wall panel, and the floor portion is located between the two parts of the columns that are bent backward.

[0014] According to some technical solutions of the present application, the rear end of the floor portion 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 portion. When the floor portion is connected to the floor module, the front end of the floor module abuts against the floor portion and the column at the same time.

[0015] According to some technical solutions of the present application, the floor module includes two crossbeams and a plurality of plate bodies, the two crossbeams are arranged at intervals, the connecting structure is configured to connect the floor portion with one end of the two crossbeams along the length direction, and the plurality of plate bodies are arranged along the length direction of the crossbeams and are respectively connected to the two crossbeams.

[0016] The technical solution of another aspect of the present application provides a packaging structure of an exchange box, comprising: the exchange box described in any of the above technical solutions: a container, wherein the front wall module and the floor module of the exchange box are distributed in the container in a state of being disassembled from each other, wherein the floor module is arranged along the length direction of the container.

[0017] In the present application, the structure for constructing the floor part is split into at least two parts, that is, at least a floor part and a floor module. For the floor module, it can be ensured that the length dimension of the floor module is smaller than the total length of the exchange box, and accordingly, it is ensured that the length dimension of the floor module is smaller than the total inner length of a standard container of the same specification as the exchange box. In this way, when the exchange box is packed into a standard container of the same specification, the floor module can be easily packed into the standard container by separating the floor part from the floor module; for the floor part, the floor part is included in the front wall module, and the packing of the front wall module basically does not occupy the length space in the container, and can also meet the packing requirements of the standard container, thereby realizing the low cost of the exchange box packaging and transportation solution. In addition, the floor part can be used to strengthen the structure and stability of the front wall module, and at the same time, it also avoids the problem of poor force caused by the rear segment of the exchange box.

[0018] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0038] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0039] In the embodiments shown in the drawings, the indications of directions (such as up, down, etc.) used to explain the structure and movement of various elements of the present invention are not absolute but relative. 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, the indications of these directions also change accordingly.

[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present invention will be more comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The accompanying drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0041] Some embodiments of the present invention provide an exchange box and a packaging structure of the exchange box.

[0042] like Figures 1 to 5 As shown, the exchange box is a combination of components assembled, and the assembled exchange box has at least a front wall portion (specifically, it can be understood as Figures 1 to 5 The front wall shown in the figure) and the floor part (specifically, it can be understood as Figures 1 to 5 The floor portion 12 and the floor module 20 shown in FIG.

[0043] For example, the front wall portion of the exchange box can be understood as a component of the exchange box that is used to be close to the front end of the skeleton vehicle.

[0044] Of course, it is understandable that the exchange box is not limited to the case where it only includes a front wall portion and a floor portion. In other embodiments, the exchange box may also include a rear wall portion or a rear door module, and / or may also include a top frame module, and / or may also include a side panel module, etc. Technicians in this field can configure the specific components of the exchange box according to needs, which will not be further elaborated here.

[0045] Among them, the components used to assemble to form the exchange box body include a front wall module 10 and a floor module 20. The front wall module 10 includes a front wall portion for constructing a front wall part and a floor portion 12 arranged on the front wall portion. A connecting structure for connecting the floor module 20 and the floor portion 12 is arranged between the floor module 20 and the floor portion 12. When the floor portion 12 is connected to the floor module 20 through the connecting structure, the floor module 20 extends backward from the floor portion 12, so that the floor portion 12 and the floor module 20 jointly construct a floor part.

[0046] Among them, the structure for constructing the floor part is split into at least two parts, that is, at least the floor part 12 and the floor module 20 are split as an example in the embodiment. For the floor module 20, it can be ensured that the length dimension of the floor module 20 is smaller than the total length of the exchange box. In this way, even if the total length of the floor part of the exchange box is the same or close to the total length of the standard container of the same specification, it can be ensured that the length dimension of the floor module 20 is always smaller than the total length of the standard container. In this way, when the exchange box is packed into a standard container of the same specification, by splitting the floor part 12 and the floor module 20, the floor module 20 can be easily packed into the standard container, and there will be no problem that the floor module 20 exceeds the total length of the standard container and cannot be packed. As for the floor portion 12, the floor portion 12 is included in the front wall module 10. It can be understood that the packaging of the front wall module 10 basically does not occupy the length space in the container. Therefore, including the floor portion 12 in the front wall module 10 will basically not affect the length space in the standard container, thereby meeting the packaging needs of the standard container, realizing the low-cost packaging and transportation plan of the exchange box body, and being better compatible with the optional plan of low transportation cost, reducing the product cost and the difficulty of transformation.

[0047] In addition, by connecting the floor portion 12 with the front wall portion, the structure and stability of the front wall module 10 can be enhanced compared to a traditional front wall portion without a floor portion 12, so that it can more reliably withstand various external force impacts during transportation and ensure the safety of the goods.

[0048] Furthermore, by integrating the floor portion 12 into the front wall module 10, the split position of the floor part (i.e., the connection position between the floor portion 12 and the floor module 20) is relatively close to the front wall part, thereby avoiding the problem of poor stress caused by the rear segmentation of the exchange box. Specifically, considering that when the exchange box is loading and unloading goods from the rear end, the forklift will enter and exit from the rear end of the exchange box, resulting in the maximum axle load possibly exceeding 7.2t, the present embodiment integrates the floor portion 12 into the front wall module 10, so that the segmentation position of the floor part is relatively close to the front wall module 10. Therefore, the problem of unreasonable exchange box bearing structure and poor stress at the rear part due to the rear end segmentation of the exchange box is well avoided, and better adaptability to working conditions is achieved, so that the product has higher reliability and stability under harsh working conditions, and ensures the safe transportation of goods. Moreover, the exchange box structure of the present embodiment also improves the lightweight potential of the exchange box, reduces the dead weight of the product, reduces the transportation cost, and also meets the requirements of energy saving and environmental protection.

[0049] For example, a positioning structure is provided between the floor module 20 and the floor portion 12. The positioning structure facilitates on-site assembly and positioning of the floor module 20 and the floor portion 12, reduces the need for special tooling and measurement workload for on-site assembly, and is conducive to improving on-site assembly accuracy and efficiency.

[0050] For example, in conjunction with the attached Figure 6 and Fig. 9 It can be understood that the floor portion 12 has a rear end plate 121; Fig.10 It can be understood that the floor module 20 includes two cross beams 22 and a plurality of plates 23. The two cross beams 22 are arranged at intervals in the left-right direction. The plurality of plates 23 are laid flat along the length direction of the cross beams 22 and are respectively connected to the two cross beams 22. The supporting surface constructed by the plates 23 is used to support the goods in the exchange box. Fig.11 As shown, a front end plate 21 is provided at one end of each cross beam 22 .

[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 abutted together, the positioning pin 1212 extends into the positioning hole 212, thereby realizing rapid positioning of the floor module 20 and the floor part 12, and has the advantages of simple structure and convenient positioning construction.

[0052] Optionally, the positioning pin 1212 can be specifically set as a cylindrical pin shaft, 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 activity in the positioning hole 212, and 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 accuracies of the floor module 20 and the floor part 12.

[0053] Of course, in other embodiments, the positioning pin 1212 may also be in other shapes, such as an elliptical cylinder, a square cylinder, a semi-cylinder, etc. The shape and size of the positioning hole 212 are roughly consistent with 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 may be provided on the front wall module or the floor module, and positioning may be performed manually or mechanically to reduce costs. In addition to using positioning pins for positioning, advanced positioning technologies such as laser positioning and sensor positioning may also be used to improve positioning accuracy and efficiency.

[0055] Optionally, the rear end plate 121 of the floor portion 12 is connected to the front end plate 21 of the floor module 20 through a connection structure. Taking the connection structure including a screw connection structure as an example, a first through hole 1211 is provided on the rear end plate 121 of the floor portion 12, and a second through hole 211 is provided on the front end plate 21 of the floor module 20. The first through hole 1211 corresponds to the second through hole 211, and screws are passed 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. Among them, by using a positioning structure, such as a positioning pin 1212 and a positioning hole 212, when the positioning pin 1212 extends into the positioning hole 212, the front end plate 21 and the rear end plate can be positioned at a position where the first through hole 1211 corresponds to the second through hole 211, thereby facilitating the assembly of the product.

[0056] Optionally, the front end plate 21 of each cross beam 22 may be Fig.11 As shown in the figure, eight second through holes 211 are provided at both ends of the rear end plate 121 of the floor portion 12. Fig. 9 As shown, 8 first through holes 1211 are provided at each end, and 8 screws are used to fix them respectively, so that the connection reliability between the floor module 20 and the floor portion 12 is higher. Of course, the number of the first through holes 1211 and the second through holes 211 at each corresponding position of the front plate 21 and the rear plate 121 is not limited to the 8 listed. In other embodiments, the number of the first through holes 1211 and the second through holes 211 at each corresponding position of the front plate 21 and the rear plate 121 can be adjusted according to specific needs, for example, set to 4, 6, 10, etc., which will not be exhaustively listed here.

[0057] It can be 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 a riveted structure, a rivet connection structure (such as a Huck nail connection structure, etc.), an adhesive structure, or a combination of a screw connection structure, a rivet connection structure, a rivet connection structure, an adhesive structure, and a welding structure. In this way, a suitable connection method can be selected according to different needs and scenarios, thereby 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 Fig. 9 and Fig.11 It can be understood that the opposing surfaces of the front end plate 21 and the rear end plate 121 are planes adapted to each other.

[0059] Of course, in other embodiments, the relative surfaces of the front end plate 21 and the rear end plate 121 can also be set as curved surfaces, inclined surfaces, or stepped surfaces, etc., and are not limited to the planes shown in the drawings. Among them, different contact surface styles can meet different structural and functional requirements, expand the design space of the product, and can also optimize the design of the contact surface according to actual conditions to improve the performance and stability of the product.

[0060] Among them, different contact surface styles can meet different structural and functional requirements, expanding the design space of the product. And the design of the contact surface can be optimized according to actual conditions to improve the performance and stability of the product.

[0061] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the front wall portion includes a wall panel 111 and two columns 112 arranged at both ends of the wall panel 111, one end of the column 112 is connected to the side of the wall panel 111, and the other end of the column 112 is bent backward relative to the wall panel 111 to form a rear bend 1121; the floor portion 12 is arranged at the bottom of the wall panel 111 and extends backward relative to the wall panel 111, and the floor portion is located between the parts of the two columns 112 that are bent backward. In this way, the floor portion 12 can support the columns 112 outwardly on both sides, so that the wall panel 111 is not easy to bend and deform, and the structural strength and stability of the front wall portion are further improved.

[0062] Optionally, combined Figure 1 and Figure 2 It can be understood that the rear end of the floor portion 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 portion 12. When the floor portion 12 is connected to the floor module 20, the front end of the floor module 20 abuts against the floor portion 12 and the column at the same time. 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 life of the product.

[0063] More specifically, for example, the wallboard 111 of the front wall is usually made of materials such as steel or aluminum alloy to provide sufficient strength and stability. Specifically, the wallboard 111 of the front wall mainly includes three panels, namely a front panel 1112, a back panel and two side panels. The front panel 1112 is a vertical plane structure used to prevent the goods from moving forward and withstand the pressure from the front. The bottom of the front panel 1112 is constructed with a floor portion 12, and the floor portion 12 is respectively provided with two protruding positioning pins 1212 near the edge of both sides. The two positioning pins 1212 cooperate with the corresponding positioning holes 212 on the floor module 20 to preliminarily locate the relative position of the front wall module 10 and the floor module 20 during assembly, ensuring that the floor portion 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 in parallel with the front panel 1112 to enhance the overall structural strength of the front wall module 10. The back panel can be a transverse corrugated plate 1111. The two side panels are connected to the two sides of the front panel 1112 and the back panel to form a closed frame structure, which further improves the stability of the front wall module 10. The columns are arranged at the corners of the connection between the side panels and the front panel 1112 and the back panel to enhance the overall structural strength and stability of the front wall module 10 and provide a positioning reference for assembly with the floor module 20.

[0064] The floor module 20 is usually made of thick wood or high-strength composite materials with high load-bearing capacity. A small part of the front end of the floor part is included in the front wall module 10. This design makes the length of the floor module 20 shorter than the inner length of a standard container and can be loaded into the container. The surface of the floor module 20 is usually anti-slip to ensure that the goods do not slide during transportation. The floor module 20 is provided with two positioning holes 212 at the front end near the edges on both sides. The two positioning holes 212 cooperate with the positioning pins 1212 of the floor part 12 at the bottom of the front panel 1112 to preliminarily locate the relative positions of the front wall module 10 and the floor module 20 during assembly.

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

[0066] The bolts completely fix the front wall module 10 to the floor module 20. During the fastening process, diagonal fastening can be used to improve the stability of the connection. In order to further improve the connection strength between the modules, a sealing gasket or sealant can be added at the contact surface to enhance the sealing performance and prevent dust, moisture, etc. from entering the module.

[0067] In practical applications, the specific structure and matching mode 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 side curtain exchange box.

[0068] The working process is as follows: for assembly, the positioning pin 1212 is fixed on the front wall module 10 to assist in positioning the front wall module 10 and the floor module 20, and then the front wall module 10 is completely fixed to the floor module 20 by bolts. Figure 1 As shown. For packaging, the front wall module 10, the floor module 20, and the bolt connection module are all packaged separately, that is, fixed. Among them, the positioning pin 1212 can be fixed on the front wall module 10, or can be packaged separately.

[0069] When connecting the front wall module 10 and the floor module 20, the positioning pins 1212 can be inserted into the corresponding holes to ensure that the two modules are initially aligned. Then, bolts or other fasteners are used to fasten them to ensure that the connection is firm and reliable. During the fastening process, diagonal fastening can be used to improve the stability of the connection.

[0070] The installation of the positioning pin 1212 can be performed by press-in or threaded connection. Press-in installation is simple and quick, but may cause certain damage to the surface of the module. Threaded connection is more secure, but the installation process is relatively complicated.

[0071] When selecting fasteners, you can choose bolts, nuts, etc. of different materials and specifications according to actual needs and use environment. For example, in a corrosive environment, you can choose stainless steel fasteners; when you need to withstand a large load, you can choose high-strength fasteners.

[0072] In order to further improve the fixing strength between modules, a sealing gasket or sealant can be added at the contact surface to enhance the sealing performance and prevent dust, moisture, etc. from entering the interior of the module.

[0073] During the packing process, the modules (such as the front wall module 10, the floor module 20, etc.) may be packed with cushioning materials such as foam plastics and air cushion films to prevent collision and damage 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 size of the product to ensure that the product can be loaded and transported smoothly.

[0075] During transportation, a fixing device may be used to fix the exchange box on the transport vehicle to prevent the exchange box from moving and shaking during the above process.

[0076] Check and maintain the module regularly to ensure that the connection parts of the module are not loose or damaged. If any problems are found, repair or replace them in time.

[0077] Some embodiments of the present application provide a packaging structure for an exchange box, comprising: the exchange box and the container as described in any of the above embodiments, the front wall module 10 and the floor module 20 of the exchange box are distributed in the container in a state of being disassembled from each other, 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 roughly consistent with the length direction inside the container.

[0078] It can be understood that, through the exchange box structure of this embodiment, it is possible to pack products into 45ft or 40ft containers, for example. Containers of other sizes can also be selected according to actual conditions, such as 20ft containers or customized containers of special sizes.

[0079] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of 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, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
