Description

Technical Field

[0001] This application relates to the field of container technology, and more specifically to a roll-shaped cargo transport device and a container. Background Technology

[0002] Due to their concentrated weight and cylindrical shape, coiled steel exerts a significant concentrated load on the load-bearing components during transportation. Furthermore, steel coils are prone to rolling, especially when subjected to vibration or impact, making them more susceptible to damage to the transport equipment. Therefore, effective loading and securing measures are essential for the transportation of steel coils. In existing container shipping, pallets are used to restrain the steel coils. Generally, pallets are laid flat on the container floor to prevent longitudinal movement during transport.

[0003] A single container may transport a single coil or multiple coils of steel. Ideally, the number of coils corresponds one-to-one with the number of pallets to avoid resource waste. Traditional pallet designs are often limited by fixed structures, making it difficult to flexibly handle coiled goods of varying quantities, sizes, and weights. In actual transport operations, if a single coil of steel needs to be transported, a fully loaded pallet may still be used.

[0004] Therefore, there is a need to provide a roll-type cargo transport device and a container to at least partially solve the above problems. Summary of the Invention

[0005] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section.

[0083] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0084] This application discloses a coiled cargo transport device 10 for transporting cylindrical cargo in a container 20. Optionally, the cylindrical cargo is coiled steel.

[0085] Reference Figures 1 to 5The roll-shaped cargo transport device 10 includes a pallet 100 and a limiting member 200. The pallet 100 is used to carry cylindrical goods. The limiting member 200 is disposed at both ends of the pallet 100 along a second direction D2. In this embodiment, the roll-shaped cargo transport device 10 has a first direction D1, a second direction D2, and a third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. When the roll-shaped cargo transport device 10 is placed in the container 20, the first direction D1 is the width direction of the container 400, the second direction D2 is the length direction of the container 400, and the third direction D3 is the height direction of the container 400. The limiting member 200 prevents the roll-shaped cargo transport device 10 from moving longitudinally during transport.

[0086] In some instances, only one set of roll-shaped cargo transport devices 10 is installed inside the container body 400 of the container 20. The roll-shaped cargo transport devices 10 are connected to the front and rear ends of the container body 400 respectively via limiting members 200.

[0087] In some instances, at least two sets of roll-shaped cargo transport devices 10 are provided inside the container body 400 of the container 20. Multiple sets of roll-shaped cargo transport devices 10 are arranged along the length direction, and the outermost (i.e., the frontmost and rearmost) roll-shaped cargo transport devices 10 can be connected to the container body 400 via limiting members 200.

[0088] like Figure 1 and Figure 4 As shown, the pallet 100 includes a base frame 110 and a stop 120. The base frame 110 is used to carry cylindrical goods. The stop 120 is connected to the base frame 110 and is used to prevent the cylindrical goods from rolling circumferentially on the base frame 110.

[0089] One end of the limiting member 200 is connected to the base frame 110, and the other end of the limiting member 200 has an unfolded position and a folded position relative to the base frame 110. For example... Figure 1 As shown, in the unfolded position, the other end of the limiting member 200 extends away from the base frame 110, and the limiting member 200 can be securely connected to the front and / or rear end of the container body 400 of the container 20 to prevent longitudinal movement of the rolled cargo transport device 10 during transport. Figure 4 As shown, in the folded position, at least part of the retaining member 200 overlaps with the base frame 110, which reduces the space occupied by the roll-shaped cargo transport device 10 when not in use, and facilitates storage and transportation.

[0090] In this design, the unfolding and folding mechanism of the limiting member 200 allows the pallet 100 to easily adapt to different quantities of rolled goods and containers 20 with varying sizes. When loading a single roll of goods, the limiting member 200 can unfold to accommodate a larger loading space. When loading multiple rolls of goods, the limiting member 200 can fold to overlap with the underframe, allowing adjacent rolled goods transport devices 10 to connect, reducing space occupation and increasing the loading capacity of the container 20. This device simplifies the loading and securing process, reducing the labor intensity and time required for operators. The rapid unfolding and folding function of the limiting member 200 enables operators to quickly secure goods, improving overall transportation efficiency. Furthermore, the secure securing of goods and high space utilization reduce delays and re-secured items during loading and unloading, further enhancing transportation efficiency.

[0091] In some embodiments of this application, at least two sets of stops 120 are arranged opposite to each other and spaced apart along a first direction D1 to divide the base frame 110 into storage areas spaced apart along the first direction D1. The storage areas include side storage areas 111 located outside the stops 120 and intermediate storage areas 112 located between adjacent stops 120. The limiting member 200 can be stored in the side storage area 111. By separating the stops 120, the support width of the stops 120 for cylindrical goods is increased while reducing the weight of the stops 120. The stops 120 can also divide the base frame 110 into multiple storage areas, allowing for more efficient use of the space in the roll-type cargo transport device 10. The side storage areas 111 facilitate the storage and unfolding of the limiting member 200, enabling the roll-type cargo transport device 10 to be assembled and disassembled more quickly during loading and unloading, thereby improving transport efficiency. Inside container 20, the side storage area 111 is closer to the side panel of container body 400.

[0092] Optionally, the stop 120 is constructed as a triangular base, and each set of stop 120 includes two triangular bases. The two triangular bases in the same set are spaced apart along the second direction D2 to form a carrying space for cylindrical goods. Triangular bases in different sets are spaced apart along the first direction D1 to form a central storage area 112. The outermost triangular base has a side storage area 111 on its outer side.

[0093] In some embodiments of this application, the base frame 110 has a first end and a second end opposite to each other along a second direction D2, and two sets of limiting members 200 are respectively connected to the first end and the second end of the base frame 110. The limiting members 200 are respectively connected to both ends of the base frame 110, which can firmly fix the position of the rolled cargo transport device 10 in the container 20 and prevent the rolled cargo transport device 10 from longitudinally shifting due to vibration or inertia during transportation. Each set of limiting members 200 includes at least two limiting rods 210 spaced apart along a first direction D1 and extending along a second direction D2. One end of the limiting rod 210 is connected to the base frame 110, and the other end is used to connect to the container 20. The limiting rods 210 extend along the second direction D2, therefore the limiting rods 210 have high strength along the second direction D2, thereby stably supporting the base frame 110. The limiting rods 210 are spaced apart along the first direction D1, providing multi-point support for the base frame 110. By distributing the force at the points of application, the load borne by the base frame 110 is evenly distributed to each limiting rod 210, avoiding stress concentration caused by excessive force at a single point. At the same time, it ensures the stability of the connection between the pallet 100 and the container 20.

[0094] In some embodiments of this application, different groups of limiting rods 210 are staggered along a first direction D1 and / or a third direction D3. Optionally, when the limiting member 200 is in the folded position, in the plane projection where the first direction D1 and the second direction D2 are both located, different groups of limiting rods 210 are staggered, that is, different groups of limiting rods 210 are staggered along the first direction D1. During folding, if the limiting rods 210 are fully aligned, they may collide or jam with each other, resulting in uneven folding or damage to the limiting member 200. The staggered design ensures that the limiting rods 210 will not interfere with each other during folding, improving the reliability and durability of folding. Optionally, different groups of limiting rods 210 are staggered along a third direction D3, and when the limiting member 200 is in the folded position, different groups of limiting rods 210 can be stacked along the third direction D3.

[0095] In some embodiments of this application, when the limiting member 200 is in the folded position, its length is less than the length of the base frame 110 along the second direction D2. The folded position is the state in which the limiting member 200 is not in use; designing its length to be less than the length of the base frame 110 minimizes space occupation. This allows the limiting member 200 to be more easily stored in the side storage area 111 or other designated location of the base frame 110. Understandably, when the limiting member 200 is in the unfolded position, its length can be adjusted to meet specific needs.

[0096] like Figure 2As shown, in some embodiments of this application, a limiting plate 220 is provided at the end of the limiting rod 210 away from the base frame 110. When the limiting member 200 is in the unfolded position, the limiting plate 220 is flush with the bottom surface of the base frame 110. That is, when the limiting member 200 is unfolded, the limiting plate 220 and the base frame 110 can be simultaneously and stably supported on the same plane, thereby increasing the stability of the roll-shaped cargo transport device 10 when carrying cargo. Specifically, it can be supported up to the bottom plate of the container 20.

[0097] like Figures 2-3 As shown, in some embodiments of this application, the limiting plate 220 protrudes from the limiting rod 210 along the third direction D3, and a reinforcing plate 230 is provided between the limiting plate 220 and the limiting rod 210. In this embodiment, the length of the base frame 110 along the third direction D3 is greater than the length of the limiting member 200 along the third direction D3. The protruding setting of the limiting plate 220 enables the limiting plate 220 to achieve stable and balanced support. The setting of the reinforcing plate 230 enhances the connection strength between the limiting plate 220 and the limiting rod 210, as well as enhances the structural strength of the limiting plate 220, making the entire limiting member 200 more stable and reliable. Optionally, the reinforcing plate 230, the limiting plate 220, and the limiting rod 210 form a triangular configuration.

[0098] Optionally, in the projection of the plane shared by the second direction D2 and the third direction D3, the total length of the limiting plate 220 and the limiting rod 210 is less than or equal to the length of the base frame 110. Therefore, as Figures 4-5 As shown, when folded, the retaining member 200 can be hidden within the base frame 110. Alternatively, the retaining member 200 can protrude from one side of the base frame 110, and the protrusion can extend into the adjacent base frame 110 above.

[0099] Based on the above embodiments, the connection between the limiting member 200 and the base frame 110 is at least one of a rotatable connection and a detachable connection.

[0100] In the above description, the rotatable connection allows the limiting member 200 to rotate or swing relative to the base frame 110 within a specific range. The limiting member 200 has a simple connection structure, high connection strength, and is easy to fold and unfold. Optionally, the limiting member 200 is rotatably connected to the base frame 110 via a pivot.

[0101] In the above, the detachable connection allows users to easily install or remove the limiting element 200 as needed. This facilitates maintenance and replacement of damaged parts, and also allows for easy adjustment of the layout of the roll-type cargo transport device 10 according to different cargo types and sizes.

[0102] Based on the above embodiments, the length of the limiting member 200 is adjustable.

[0103] In the above description, the adjustable length of the limiting member 200 allows the roll-type cargo transport device 10 to accommodate goods of different sizes and shapes. By adjusting the length of the limiting member 200, the user can ensure that the goods are firmly supported and secured on the roll-type cargo transport device 10. When the entire limiting member 200 is not needed, it can be shortened and stored, thereby saving space. Optionally, the limiting member 200 can be stored directly by shortening, or it can be stored after shortening by the aforementioned rotating or detachable connection.

[0104] like Figures 10-12 As shown in this application, the container body 400 of the container 20 has a front end and a rear end that are arranged opposite to each other along its length. The two sets of limiting members 200 of the aforementioned roll-shaped cargo transport device 10 are respectively connected to the front end and the rear end of the container body 400. Optionally, corner posts are provided at each of the four corners of the container body 400.

[0105] Optionally, the front and rear ends of the enclosure 400 can be configured as either end walls or doors 420. Optionally, the ends are fixed to the corner posts. The doors 420 are optionally connected to the corner posts.

[0106] An end beam 410 is provided on the end wall. When the end of the box 400 is provided as an end wall, the limiting member 200 of the roll-shaped cargo transport device 10 can be directly supported to the end beam 410.

[0107] When the end of the box 400 is set as a door 420, since the door 420 is openable and closable, the limiting member 200 cannot be directly supported to the door 420.

[0108] like Figure 1 , Figures 3-4 As shown, in some embodiments of this application, the roll-shaped cargo transport device 10 further includes a fixing member 300. The fixing member 300 can be connected to the limiting member 200. Figure 3 and Figure 5 As shown, the end of the limiting member 200 away from the base frame 110 is provided with a connecting portion 240, and the limiting member 200 is connected to the fixing member 300 through the connecting portion 240. Optionally, the connecting portion 240 is constructed as a ring structure so that it can be sleeved onto the outer periphery of the fixing member 300.

[0109] like Figure 11 As shown, the rolled cargo transport device 10 is connected to the corner posts via a fastener 300. Optionally, the corner posts include an inner corner post 430 and an outer corner post 431. The inner corner post 430 and the outer corner post 431 are spaced apart to form a groove 432. The fastener 300 extends into the groove 432.

[0110] In some embodiments of this application, the length of the fastener 300 is adjustable, and the fastener 300 has a first length and a second length, with the first length being greater than the second length. When the length of the fastener 300 is the first length, the fastener 300 can be connected to the limiting member 200. When the length of the fastener 300 is the second length, the fastener 300 can be stored in the middle storage area 112 of the base frame 110. That is, when the fastener 300 does not need to be connected to the limiting member 200, it can be adjusted to the shorter second length and stored in the middle storage area 112 of the base frame 110, which not only saves space but also makes the roll-shaped cargo transport device 10 more compact, facilitating storage and transportation. Although the fastener 300 and the limiting member 200 are separate structures, when separated from the limiting member 200, it can be connected to the base frame 110.

[0111] like Figures 6-9 As shown, in some embodiments of this application, the fastener 300 includes a body portion 310 and an extension portion 320, the extension portion 320 being movably connected to the body portion 310 between an extended position and a shortened position. The connection between the extension portion 320 and the body portion 310 can be at least one of a rotatable connection, a detachable connection, or a sliding connection.

[0112] Optionally, two extensions 320 are provided. The two extensions 320 are provided at both ends of the main body 310 along the length direction.

[0113] In the above description, the extension 320 is allowed to rotate or swing relative to the main body 310 within a specific range through a rotatable connection. The connection structure of the extension 320 is simple and has high connection strength; the length of the fixing member 300 can be shortened or lengthened by folding and unfolding operations. Optionally, the extension 320 is rotatably connected to the main body 310 via a pivot.

[0114] In the above, the detachable connection allows the user to easily install or remove the extension 320 as needed. This facilitates maintenance and replacement of damaged parts, and also allows for easy adjustment of the size of the fastener 300 according to different types and sizes of goods.

[0115] In the above description, the adjustable length of the fastener 300 allows it to adapt to boxes 400 of different sizes and shapes. By adjusting the length of the fastener 300, the user can ensure that the rolled cargo transport device 10 is securely supported and fixed within the box 400. When not using all of the fasteners 300, they can be shortened to a suitable length to support the box 400. Alternatively, they can be shortened and stored away to save space. Optionally, the fastener 300 can be stored directly by shortening, or it can be stored after shortening via the aforementioned rotatable or detachable connection.

[0116] Based on the above embodiment, the main body 310 is constructed as a channel steel, and the extension 320 located in the shortened position can be housed within the channel steel. The width of the extension 320 is smaller than the width of the main body 310.

[0117] In some embodiments of this application, the length of the base frame 110 along the first direction D1 is less than the first length. That is, when the extension 320 of the fastener 300 is in the extended position, the length of the base frame 110 along the first direction D1 is less than the length of the fastener 300. The fastener 300 can support the corner posts with a large spacing.

[0118] In some embodiments of this application, the length of the base frame 110 along the second direction D2 is greater than the second length. That is, when the extension 320 of the fastener 300 is in the shortened position, the length of the base frame 110 along the second direction D2 is greater than the length of the fastener 300. The fastener 300 can be stored in the intermediate storage area 112.

[0119] In some embodiments of this application, such as Figure 10 As shown, the central storage area 112 of the base frame 110 has a first connecting hole 113. (As indicated...)
