Description

Technical Field

[0001] This utility model generally relates to the technical field of container structures, and more specifically to a container. Background Technology

[0002] Liquid transport containers can efficiently transport various bulk liquid raw materials such as alcoholic beverages, oils, chemical liquids, and pharmaceuticals. Container types include tank containers, liquid bag containers, and general-purpose containers, catering to diverse transport conditions under ocean, road, and rail transport. Tank containers can be directly filled with liquids, liquid bag containers require liquid transport bags to be laid inside before filling, and general-purpose containers require stacking tank containers inside.

[0003] By comparison, tank containers offer extremely high efficiency in transporting liquid cargo, requiring no additional tools or preparation. Furthermore, for the same external dimensions, tank containers have a larger tank volume, 45% more than standard containers. The structure of a tank container primarily consists of a tank body and a fixedly connected frame. Typically, the tank body is designed in a capsule shape; while this shape enhances the tank's strength and weld sealing, it reduces some of the tank volume. Square tank bodies can further increase the tank volume compared to round tank bodies. Existing square tank bodies adopt the shape of a square container, with corrugated plates and internal reinforcing ribs used for the front, rear, and side walls. Although this design uses a combination of corrugated plates and internal reinforcing ribs to strengthen the four sides, it is still difficult to withstand the internal pressure during the transport of liquid cargo over a long period, easily leading to deformation and ultimately, the container breaking.

[0004] Therefore, there is a need to provide a container that can at least partially solve the above problems. Utility Model Content

The top plate 320 includes a first cover plate 321, which is adapted to the end plate 313. The top surface of the first cover plate 321 is also constructed as an upwardly convex arcuate surface.

[0026] According to this design, the container 100, with its bottom plate 311, side plates 312, and end plates 313 forming a box structure 310, increases the canning volume compared to existing capsule-shaped tanks. Furthermore, the top surface of the end plates 313 is a convex arc-shaped surface, further increasing the canning volume. An outer frame 200 is provided around the tank 300 to enhance its strength, enabling it to withstand internal pressure during long-term transport of liquid goods, preventing deformation and breakage.

[0027] Furthermore, the base plate 311, side plate 312 and end plate 313 are all fixedly connected to the outer frame 200.

To improve the structural strength and sealing of the container structure 310, the container 100 also includes a first reinforcing member 314, which is disposed in the tank body 300. Specifically, the first reinforcing member 314 is disposed inside the tank body 300, and a single first reinforcing member 314 is connected to the bottom plate 311, side plates 312, and end plates 313. Figure 6 The structure of a first reinforcing member 314 is shown. The first reinforcing member 314 includes a side plate reinforcing member 327, an end plate reinforcing member 328, and a bottom plate reinforcing member 329. Specifically, the side plate reinforcing member 327 is connected to the inner wall surface of the side plate 312; the end plate reinforcing member 328 is perpendicular to the side plate reinforcing member 327 and connected to the inner wall surface of the end plate 313. Both the side plate reinforcing member 327 and the end plate reinforcing member 328 are provided with flanges, for example, referred to as a first flange and a second flange. The first flange is perpendicular to the side plate reinforcing member 327 and one end is connected to the side plate reinforcing member 327. The second flange is perpendicular to the end plate reinforcing member 328 and one end is connected to the end plate reinforcing member. The other end of the first flange away from the side plate reinforcing member 327 extends along the width direction DW of the container 100 towards a position close to the center of the container 100. The other end of the second flange away from the end plate reinforcing member 328 extends along the length direction DL of the container 100 towards a position close to the center of the container 100. The first and second flanges intersect to form the base plate reinforcement 329. The base plate reinforcement 329 is connected to the upper surface of the base plate 311. It can be understood that the aforementioned side plate reinforcement 327, end plate reinforcement 328, and base plate reinforcement 329 can be constructed as an integrally formed bent structure. The base plate 311 is connected to the base frame 210. The side plate 312 corresponds to the side frame 220, and the end plate 313 corresponds to the end frame 230. It should be noted that the wall thickness of the box structure 310 ranges from 2mm to 6mm, for example, any suitable value such as 2mm, 3mm, 4mm, 5mm, 6mm, etc. Preferably, the wall thickness of the box structure 310 is 3mm. In other words, the thickness of the aforementioned base plate 311, side plate 312, and end plate 313 ranges from 2mm to 6mm.

There are multiple bottom crossbeams 212, which are spaced apart along the length direction DL of the container 100. The outer frame 200 also includes a second reinforcing member 213, which is connected to the bottom side beams 211. It should be noted that both the aforementioned bottom side beams 211 and bottom crossbeams 212 can be constructed as C-shaped steel, and the underframe 210 is constructed by welding multiple C-shaped steel sections together. It is understood that the cross-section of the bottom beam 211 is roughly U-shaped, and the second reinforcing member 213 can be set inside the U-shaped structure.

[0041] Since the connecting hole 240 is located at the rear end frame 232, the formation of the connecting hole 240 at the rear end frame 232 will be explained below.

[0042] Furthermore, the third reinforcing assembly 245 also includes a first reinforcing crossbeam 241, which is arranged along the width direction DW of the container 100. Both ends of the first reinforcing crossbeam 241 are connected to a pair of corner posts 233. The first reinforcing crossbeam 241 is located between the top beam 234 and the bottom beam 238. It can be understood that both ends of the first reinforcing longitudinal beam 243 are connected to the top beam 234 and the first reinforcing crossbeam 241, respectively. Along the height direction DH of the container 100, the distance between the first reinforcing crossbeam 241 and the top beam 234 is greater than the distance between the first reinforcing crossbeam 241 and the bottom beam 238. The third reinforcing assembly 245 also includes a spacer 247, a second reinforcing longitudinal beam 248, and a third reinforcing crossbeam 251. Specifically, the second reinforcing longitudinal beam 248 is arranged along the height direction DH of the container 100, and both ends of the second reinforcing longitudinal beam 248 are connected to the first reinforcing crossbeam 241 and the bottom beam 238, respectively. The spacer 247 is connected at both ends to the first reinforcing crossbeam 241 and the bottom beam 238, respectively. The spacer 247 is constructed as a plate-like member. The spacers 247 are arranged in pairs, with the pairs spaced apart along the width direction DW of the container 100. There are at least two second reinforcing longitudinal beams 248, which are arranged along the width direction DW of the container 100. For example... Figure 3 In the container 100, the second reinforcing longitudinal beams 248 are arranged in pairs, with the two pairs of second reinforcing longitudinal beams 248 spaced apart along the width direction DW. Furthermore, the aforementioned two spacers 247 are located between the two pairs of second reinforcing longitudinal beams 248. A third reinforcing crossbeam 251 is arranged between adjacent second reinforcing longitudinal beams 248 and spacers 247 along the width direction DW of the container 100. The third reinforcing crossbeam 251 is arranged along the width direction DW of the container 100 and connected to the spacers 247 and the second reinforcing longitudinal beams 248. The third reinforcing crossbeam 251 is also connected, for example, to the upper surface of the bottom beam 238. It is understood that the spacers 247, the first reinforcing crossbeam 241, and the bottom beam 238 enclose a connecting hole 240.

[0043] Please see now Figure 3 , Figure 12 and Figure 13 The connection between the second cover plate 246 and the connecting hole 240 is described below.

[0044] The second cover plate 246 is configured, for example, to be pivotally connected to the end frame 230 between the open and closed positions about an axis extending along the width direction of the container 100. When the second cover plate 246 is in the closed position, it covers the communication hole 240 and the control valve 315 located inside the communication hole 240. A spring pin 250 is also provided at the end frame 230 to limit the second cover plate 246 in the closed position. The spring pin 250 is provided along the width direction DW of the container 100. The spring pins 250 are arranged in pairs, spaced apart along the width direction DW of the container 100 and located on both sides of the second cover plate 246.

[0045] Please return to the reference section. Figure 1 , Figure 2 , Figure 4 and Figure 5 It can be understood that the tank body 300 is located inside the outer frame 200, the top of the tank body 300 is connected to the top plate 320, and the control valve 315 extends to the connecting hole 240.

[0046] Furthermore, the bottom plate 311 is connected to the base frame 210, the side plate 312 is connected to the side frame 220, and the end plate 313 is connected to the end frame 230. A first connection point exists between the bottom plate 311 and the outer frame 200. A second connection point exists between the side plate 312 and the outer frame 200. A third connection point exists between the end plate 313 and the outer frame 200. For example, at least one of the bottom plate 311, side plate 312, and end plate 313 is fixedly connected to the outer frame 200 by intermittent welding. That is, the container 100 also satisfies at least one of the following conditions: The bottom plate 311 and the outer frame 200 have multiple first connection positions, which are distributed at intervals along the length direction DL and / or the width direction DW of the container 100. The side panel 312 and the outer frame 200 have multiple second connection positions, which are spaced apart along the length direction DL and / or height direction DH of the container 100; and There are multiple third connection positions between the end plate 313 and the outer frame 200, and the multiple third connection positions are distributed at intervals along the width direction DW and / or height direction DH of the container 100.

[0047] Furthermore, a filling layer is provided between two adjacent first connection positions along the length direction DL and / or the width direction DW of the container 100; and / or a filling layer is provided between two adjacent second connection positions along the length direction DL and / or the height direction DH of the container 100; and / or a filling layer is provided between two adjacent third connection positions along the width direction DW and / or the height direction DH of the container 100.

[0048] Preferably, the bottom plate 311, side plates 312, and end plates 313 are all fixed to the outer frame 200 by intermittent welding. Specifically, the bottom surface 318 of the bottom plate 311 is connected to the base frame 210. The side plates 312 (or the outer surface 317 of the container 100) are connected to the side frames 220. The end plates 313 (or the outer end faces 316 of the container 100) are connected to the end frames 230. Multiple first connection positions are spaced apart along the length direction DL and width direction DW of the container 100. Multiple second connection positions are spaced apart along the length direction DL and height direction DH of the container 100. Multiple third connection positions are spaced apart along the width direction DW and height direction DH of the container 100. It is understood that a filling layer is provided between two adjacent first connection positions along the length direction DL and width direction DW of the container 100. A filling layer is provided between two adjacent second connection positions along the length direction DL and height direction DH of the container 100. A filling layer is provided between two adjacent third connection positions along the width direction DW and height direction DH of container 100.

[0049] The aforementioned first connection position, second connection position and third connection position can all be welds between the tank body 300 and the outer frame 200. The filling layer can be constructed as a sealant placed between adjacent welds. The sealant can prevent corrosion at the weld position and can increase the aesthetics of the connection position between the tank body 300 and the outer frame 200.

[0050] The top plate 320 and the tank body 300 are generally connected by welding, and once installed, they are generally not disassembled. Therefore, the container 100 may also include a fourth reinforcing member 322 (see...). Figure 2 and Figure 4 The fourth reinforcing member 322 is connected to the top plate 320 and the tank body 300.

[0051] According to this utility model, the container body is preferably made of stainless steel. The top of the end plate of the tank body has an upwardly convex arc shape, allowing the tank to carry more liquid cargo. Stainless steel has high strength, oxidation resistance, and corrosion resistance, and can directly contact most liquid cargoes. A reinforcing component is provided at the top plate to increase the strength of the tank top. The tank body is equipped with a control valve (e.g., a butterfly valve) for easy filling and emptying. A manhole and a breather valve are provided at the top plate; the manhole can also be used for filling and emptying, and the breather valve can regulate the internal gas pressure of the tank. The outer frame provides reinforcement and support for the tank body. Ladders are provided at the ends of the outer frame and inside the tank body for easy manual access. The tank body and the outer frame are welded together, and gaps are eliminated through a filler layer to fix the tank body and prevent it from sliding.
