Description

Technical Field

[0001] The present application relates to the technical field of containers, and more specifically to a rolled cargo transportation device and a container. Background Art

[0002] Due to the characteristics of concentrated weight and cylindrical shape, steel coils will generate large concentrated loads on the load-bearing components during transportation. At the same time, steel coils are easy to roll, especially when subjected to vibration or impact, which is more likely to cause damage to the load-bearing transportation equipment. Therefore, effective loading reinforcement measures must be taken for steel coil transportation. In existing container transportation, the position of steel coils is limited by pallets. Generally, pallets are laid flat on the floor of the container to avoid longitudinal movement during transportation.

[0003] A container may transport a single coil or multiple coils. In ideal transportation, the number of coils corresponds to the number of pallets to avoid waste of resources. Traditional pallet design is often limited by fixed structure and is difficult to flexibly handle coils of different quantities, sizes and weights. In actual transportation production, if a single coil is to be transported, a fully loaded pallet may still be used.

[0004] Therefore, it is necessary to provide a roll cargo transportation device and a container to at least partially solve the above problems. Summary of the invention

[0033] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0034] The present application discloses a rolled cargo transport device 10 for transporting cylindrical cargo in a container 20. Optionally, the cylindrical cargo is a rolled steel.

[0035] Reference Figures 1 to 5 , the roll cargo transport device 10 includes a pallet 100 and a limiter 200. The pallet 100 is used to carry cylindrical cargo. The limiters 200 are arranged at both ends of the pallet 100 along the second direction D2. In this embodiment, the roll 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 cargo transport device 10 is placed in the container 20, the first direction D1 is the width direction of the box body 400, the second direction D2 is the length direction of the box body 400, and the third direction D3 is the height direction of the box body 400. The setting of the limiter 200 prevents the roll cargo transport device 10 from longitudinal movement during transportation.

[0036] In some examples, only one set of roll cargo transport devices 10 is disposed in the box body 400 of the container 20. The roll cargo transport devices 10 are connected to the front end and the rear end of the box body 400 respectively through the stoppers 200.

[0037] In some examples, at least two groups of roll cargo transport devices 10 are disposed in the box body 400 of the container 20. The multiple groups of roll cargo transport devices 10 are arranged along the length direction, and the roll cargo transport devices 10 located at the outermost side (i.e., the frontmost and rearmost ends) can be connected to the box body 400 through the stopper 200.

[0038] like Figure 1 and Figure 4 As shown, the pallet 100 includes a base frame 110 and a stopper 120. The base frame 110 is used to carry cylindrical goods. The stopper 120 is connected to the base frame 110 and is used to prevent the cylindrical goods from rolling circumferentially on the base frame 110.

[0039] 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. Figure 1 As shown, in the unfolded position, the other end of the stopper 200 extends in a direction away from the base frame 110, and the stopper 200 can be firmly connected to the front and / or rear end of the container 20 body 400 to prevent the roll cargo transport device 10 from moving longitudinally during transportation. Figure 4 As shown, in the folded position, at least a portion of the limiting member 200 overlaps with the base frame 110, which can reduce the space occupied by the roll cargo transport device 10 when not in use, making it easier to store and transport.

[0040] In this solution, the pallet 100 can easily adapt to containers 20 with different numbers of rolled goods and different spaces through the expansion and folding settings of the limiter 200. When loading a single roll of goods, the limiter 200 can be expanded to allow the rolled goods transport device 10 to adapt to a larger loading space. When loading multiple rolls of goods, the limiter 200 can be folded to a state of overlapping with the base frame, so that adjacent rolled goods transport devices 10 are connected, reducing the space occupied and increasing the loading capacity of the container 20. This device simplifies the loading and fixing process of goods, reduces the labor intensity and time required for operators. The rapid expansion and folding function of the limiter 200 enables operators to quickly complete the fixing of goods, thereby improving the overall transportation efficiency. At the same time, since the goods are firmly fixed and the space utilization rate is high, the delays and re-fixing times during loading and unloading are reduced, further improving the transportation efficiency.

[0041] In some embodiments of the present application, at least two groups of stoppers 120 are arranged oppositely and at intervals along the first direction D1 to divide the base frame 110 into storage areas spaced along the first direction D1, and the storage areas include side storage areas 111 located outside the stoppers 120, and middle storage areas 112 located between adjacent stoppers 120. The stopper 200 can be stored in the side storage area 111. By arranging the stoppers 120 in a separated manner, the support width of the stopper 120 for the cylindrical cargo is increased while the weight of the stopper 120 is reduced. The stopper 120 can also divide the base frame 110 into multiple storage areas, which can more effectively utilize the space of the roll cargo transport device 10. The setting of the side storage area 111 allows the stopper 200 to be easily stored and unfolded, and the roll cargo transport device 10 can be assembled and disassembled more quickly during loading and unloading, thereby improving transportation efficiency. In the container 20 , the side storage area 111 is closer to the side plate of the box body 400 .

[0042] Optionally, the stopper 120 is configured as a triangular seat, and each group of the stopper 120 includes two triangular seats. The two triangular seats of the same group are spaced along the second direction D2 to form a carrying space for cylindrical goods. The tripods of different groups are spaced along the first direction D1 to form a middle storage area 112. The outer side of the outermost tripod is the side storage area 111.

[0043] In some embodiments of the present application, the chassis 110 has a first end and a second end opposite to each other along the second direction D2, and two sets of stoppers 200 are respectively connected to the first end and the second end of the chassis 110. The stoppers 200 are respectively connected to both ends of the chassis 110, and can firmly fix the position of the roll cargo transport device 10 in the container 20, and prevent the roll cargo transport device 10 from longitudinally moving due to vibration or inertia during transportation. Each set of stoppers 200 includes at least two stopper rods 210 spaced along the first direction D1 and extending along the second direction D2. One end of the stopper rod 210 is connected to the chassis 110, and the other end is used to connect to the container 20. The stopper rod 210 extends along the second direction D2, so the stopper rod 210 has a higher strength along the second direction D2, so that the chassis 110 can be stably supported. The limiting rods 210 are spaced along the first direction D1 to achieve multi-point support for the base frame 110, and the load borne by the base frame 110 is evenly distributed to each limiting rod 210 by dispersing the points of force, thereby avoiding the problem of stress concentration caused by excessive force at a single point, and ensuring the stability of the connection between the pallet 100 and the container 20.

[0044] In some embodiments of the present application, different groups of limiting rods 210 are staggered along the first direction D1 and / or the third direction D3. Optionally, in the state where the limiting member 200 is located in the folded position, in the plane projection where the first direction D1 and the second direction D2 are 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 the folding process, if the limiting rods 210 are completely aligned, they may collide or get stuck with each other, resulting in unsmooth folding or damage to the limiting member 200. Through the staggered design, it can be ensured that the limiting rods 210 will not interfere with each other during the folding process, thereby improving the reliability and durability of the folding. Optionally, different groups of limiting rods 210 are staggered along the third direction D3, and in the state where the limiting member 200 is located in the folded position, different groups of limiting rods 210 can be overlapped along the third direction D3.

[0045] In some embodiments of the present application, when the stopper 200 is in the folded position, the length of the stopper 200 is less than the length of the chassis 110 along the second direction D2. The folded position is the state of the stopper 200 when not in use. At this time, the length of the stopper 200 is designed to be less than the length of the chassis 110, which can minimize the space occupied. Thus, the stopper 200 can be more easily stored in the side storage area 111 or other designated positions of the chassis 110. It can be understood that when the stopper 200 is in the unfolded position, the length of the stopper 200 can be adjusted to meet the needs.

[0046] like Figure 2As shown, in some embodiments of the present application, a limiting plate 220 is provided at the end of the limiting rod 210 away from the bottom frame 110, and when the limiting member 200 is in the unfolded position, the limiting plate 220 is flush with the bottom surface of the bottom frame 110. That is, when the limiting member 200 is unfolded, the limiting plate 220 and the bottom frame 110 can be supported to the same plane at the same time and stably, thereby increasing the stability of the roll cargo transport device 10 when carrying cargo. Specifically, it can be supported to the bottom plate of the container 20.

[0047] like Figure 2-Figure 3 As shown, in some embodiments of the present 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 chassis 110 along the third direction D3 is greater than the length of the limiting member 200 along the third direction D3. By setting the limiting plate 220 protruding, the limiting plate 220 can be supported stably and balanced. The setting of the reinforcing plate 230 enhances the connection strength between the limiting plate 220 and the limiting rod 210, and enhances the structural strength of the limiting plate 220, so that the entire limiting member 200 is more stable and reliable. Optionally, the reinforcing plate 230, the limiting plate 220 and the limiting rod 210 form a triangular configuration.

[0048] Optionally, in the projection of the plane where the second direction D2 and the third direction D3 are located, 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. Figure 4-Figure 5 As shown, when folded, the limiting member 200 can be hidden in the bottom frame 110. Alternatively, the limiting member 200 can protrude from one side of the bottom frame 110, and the protruding portion can extend to the adjacent bottom frame 110 above.

[0049] On the basis of the above-mentioned embodiment, the connection form between the limiting member 200 and the base frame 110 is at least one of a rotating connection and a detachable connection.

[0050] In the above, the stopper 200 is allowed to rotate or swing relative to the base frame 110 within a specific range through the rotation connection. The connection structure of the stopper 200 is simple, the connection strength is high, and the folding and unfolding operations are simple. Optionally, the stopper 200 is rotationally connected to the base frame 110 via a rotating shaft.

[0051] In the above, the detachable connection allows the user to easily install or remove the limiting member 200 as needed, which is convenient for maintenance and replacement of damaged parts, and also convenient for adjusting the layout of the roll cargo transport device 10 according to different cargo types and sizes.

[0052] Based on the above embodiment, the length of the limiting member 200 is adjustable.

[0053] In the above, the adjustability of the length of the stopper 200 enables the roll-shaped cargo transport device 10 to adapt to cargo of different sizes and shapes. By adjusting the length of the stopper 200, the user can ensure that the cargo is firmly supported and fixed on the roll-shaped cargo transport device 10. When the entire stopper 200 is not needed, it can be shortened and stored to save space. Optionally, the stopper 200 can be stored directly by shortening, or can be stored by the aforementioned rotating connection or detachable connection after shortening.

[0054] like Figure 10-12 As shown, in the present application, the box body 400 of the container 20 has a front end and a rear end arranged opposite to each other along its length direction, and the two sets of stoppers 200 of the roll cargo transport device 10 are respectively connected to the front end and the rear end of the box body 400. Optionally, corner posts are arranged at the four corners of the box body 400.

[0055] Optionally, the front and rear ends of the box body 400 can be configured as one of an end wall and a box door 420. Optionally, the ends are fixedly connected between corner columns. The box door 420 is optionally connected to the corner column.

[0056] The end wall is provided with an end beam 410. When the end of the box body 400 is provided as an end wall, the stopper 200 of the roll cargo transport device 10 can be directly supported to the end beam 410.

[0057] When the end of the box body 400 is configured as a box door 420 , since the box door 420 is configured to be openable and closable, the limiting member 200 cannot be directly supported by the box door 420 .

[0058] like Figure 1 , Figure 3-Figure 4 As shown, in some embodiments of the present application, the roll 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 via the connecting portion 240. Optionally, the connecting portion 240 is configured as an annular structure so as to be sleeved on the outer periphery of the fixing member 300.

[0059] like Fig.11 As shown, the roll cargo transport device 10 is connected to the corner post by a fixing member 300. Optionally, the corner post includes 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 fixing member 300 extends to the groove 432.

[0060] In some embodiments of the present application, the length of the fixing member 300 is adjustable, and the fixing member 300 has a first length and a second length, and the first length is greater than the second length. When the length of the fixing member 300 is the first length, the fixing member 300 can be connected to the limiter 200. When the length of the fixing member 300 is the second length, the fixing member 300 can be stored in the middle storage area 112 of the base frame 110. That is, when the fixing member 300 does not need to be connected to the limiter 200, it can be adjusted to a 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 cargo transportation device 10 more compact and convenient for storage and transportation. Although the fixing member 300 and the limiter 200 are split structures, it can be connected to the base frame 110 when it is separated from the limiter 200.

[0061] like Figure 6-Figure 9 As shown, in some embodiments of the present application, the fixing member 300 includes a main body 310 and an extension 320, and the extension 320 is movably connected to the main body 310 between an extended position and a shortened position. The connection between the extension 320 and the main body 310 is at least one of a rotating connection, a detachable connection, and a sliding connection.

[0062] Optionally, two extension portions 320 are provided. The two extension portions 320 are provided at two ends of the main body portion 310 along the length direction.

[0063] In the above, the extension part 320 is allowed to rotate or swing relative to the main body 310 within a specific range through the rotation connection. The connection structure of the extension part 320 is simple and the connection strength is high. By folding and unfolding operations, the length of the fixing member 300 can be shortened or extended. Optionally, the extension part 320 is rotationally connected to the main body 310 through a rotating shaft.

[0064] In the above, the detachable connection allows the user to easily install or remove the extension part 320 as needed, which is convenient for maintenance and replacement of damaged parts, and also convenient for adjusting the size of the fixing member 300 according to different types and sizes of goods.

[0065] In the above, the adjustability of the length of the fixing member 300 enables the fixing member 300 to adapt to boxes 400 of different sizes and shapes. By adjusting the length of the fixing member 300, the user can ensure that the roll cargo transport device 10 is firmly supported and fixed in the box 400. When it is not necessary to use all the fixing members 300, it can be shortened to a suitable length to support the box 400. Or it can be shortened and stored to save space. Optionally, the fixing member 300 can be stored directly by shortening, or it can be stored by the aforementioned rotating connection or detachable connection after shortening.

[0066] On the basis of the above embodiment, the main body 310 is constructed as a channel steel, and the extension part 320 located at the shortened position can be received in the channel steel. The width of the extension part 320 is smaller than the width of the main body 310 .

[0067] In some embodiments of the present application, the length of the base frame 110 along the first direction D1 is less than the first length. That is, when the extension portion 320 of the fixing member 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 fixing member 300. The fixing member 300 can be supported between corner columns with larger spacing.

[0068] In some embodiments of the present application, the length of the bottom frame 110 along the second direction D2 is greater than the second length. That is, when the extension portion 320 of the fixing member 300 is in the shortened position, the length of the bottom frame 110 along the second direction D2 is greater than the length of the fixing member 300. The fixing member 300 can be stored in the middle storage area 112.

[0069] In some embodiments of the present application, Fig.10 As shown, the middle storage area 112 of the bottom frame 110 is provided with a first connection hole 113. Figure 6 , Figure 8-Figure 9 As shown, the fixing member 300 is provided with a second connection hole 301. When the fixing member 300 is stored in the middle storage area 112, the first connection hole 113 corresponds to the second connection hole 301 and can be fixed by a fastener. The fixing member 300 can be fixed to the middle storage area 112 of the base frame 110 through the cooperation of the first connection hole 113, the second connection hole 301 and the fastener. The connection between the fixing member 300 and the base frame 110 is tight and firm, and the installation and removal process can be completed quickly.

[0070] like Fig.13 As shown, the roll cargo transport device 10 provided by the present application can be stacked. Optionally, two stacks can be placed in the container 20, each stack can be stacked 9 layers, and a single container can transport 18 sets.
