Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.

In the embodiments shown in the drawings, directional references (such as upper, lower, left, right, front and rear) are used to explain the structure and movement of the various elements of the invention, rather than absolute, and relative. These descriptions are appropriate when the elements are in the positions shown in the drawings. If the description of the positions of these elements changes, the indication of these directions changes accordingly.

Exemplary embodiments of the present application are further described in detail below with reference to the drawings of the present specification.

Fig. 1-2 are schematic structural views of an end frame of a tank container and a coupling ring thereof. An end block according to an exemplary embodiment of the present application is described below with reference to fig. 1-2.

As shown in fig. 1-2, the end bell 2 may include: two corner posts 21, an end sill 22 connected between the bottom ends of the two corner posts 21, and a connecting ring 23 for passing through the tank body 10 (see fig. 3) of the tank container. In the example of fig. 1-2, the two corner posts 21 are substantially parallel, it being understood that they may be angled in other examples. The end lower beam 22 connects the bottom ends of the two corner posts 21.

In the example of fig. 1-2, both ends of the end sill 22 are connected to the bottom ends of the corner posts 21 through connecting blocks 27, wherein an avoiding groove 28 is provided between the end sill 22 and the bottom ends of the corner posts 21, and the avoiding groove 28 is used for avoiding a fixed lock or the like on the vehicle frame. The end sill 22 is prevented from being collided and damaged when the end frame structure 2 is placed on the vehicle frame. The connecting block 27 can strengthen the strength of the end lower beam 22 and the avoiding groove 28, and avoid the influence of the avoiding groove 28 on the overall strength of the end lower beam 22 on the end lower beam 22. In the example of fig. 1-2, the bottom end of the corner post 21 is connected to a bottom corner piece 26, and both ends of the end lower beam 22 are connected to the bottom corner piece 26 through connecting pieces 27, respectively.

The connection ring 23 serves to contact and support the tank body 10 (see fig. 3) of the tank container, and thus the shape of the inner side wall 233 thereof may be a shape that is fitted to the side wall of the tank body 10, for example, a circular arc shape. In the example of fig. 1-2, the connecting ring 23 may be a ring-shaped member having an opening 231, the left and right side portions of which are connected to the two corner posts 21, respectively, the lower side portion of which is connected to the end sill 22, and the opening 231 is located at the upper side portion of the connecting ring 23. In one example, the connecting ring 23 is tangent to both the corner posts 21 and the end sill 22 to provide a stable support for the tank. The connecting ring 23 may be connected to the corner posts 21 and the end sill 22 by welding, by a connector connection, or the like.

In one example, the opening 231 is sized smaller than a semicircle such that the left and right portions of the attachment loop 23 extend upwardly from their connection with the corner post 21 by a portion, respectively, to both sides 231A and 231B of the opening 231. The opening 231 of the upper side part of the connecting ring 23 of the end frame 2 enables the connecting ring 23 to form a non-closed structure, so that the manufacturing is convenient, the dead weight is reduced, and the heat preservation effect is promoted.

As shown in fig. 1-2, the attachment ring 23 may further include an arcuate plate 232 disposed between the sides 231A, 231B of the opening 231 and the associated respective corner post 21. It should be understood that the arcuate plate 232 may be disposed between only one of the two sides 231A, 231B of the opening 231 and the corresponding corner post 21, while the other side 231B or 231A is not provided or provided with a connecting plate of other profile shape. In the example of fig. 1-2, the arcuate plate 232 is shown as a downwardly concave arcuate plate 232. In one example, the arcuate plate 232 is tangent to the inner sidewall 233 of the connecting loop 23 and/or the connected corner post 21. In one example, the radius of curvature of the arcuate plate 232 may be 0.1-0.2m, and preferably, may be 0.12 m. The curved plate 232 allows the connecting ring 23 to be more evenly distributed of stresses experienced by the container body 10, reducing or preventing damage to components that might otherwise result from stress concentrations.

In one example, the connecting ring 23 can be formed as two parts, a front piece 23A and a back piece 23B, which have the same shape, and the arc-shaped plate 232 is connected between the front piece 23A and the back piece 23B. The front sheet 23A may be attached to the front side of the end frame 2 and the rear sheet 23B may be attached to the rear side of the end frame 2. The connecting ring 23 can be produced in one piece or in blocks and then assembled.

In the example of fig. 1-2, the end frame 2 further includes an end upper beam 24 connected between the top ends of the two corner posts 21. In the example of fig. 1-2, two corner posts 21 have top corners 26 attached to their top ends, and upper end beams 24 have both ends attached to the two top corners 26. It should be understood that end stile 2 may not include end upper rail 24.

In the example of fig. 1-2, the coupling ring 23 further includes a tank gasket 234 disposed on an inner sidewall 233 that contacts the tank 10. In one example, a tank liner 234 is laid over the entire inner sidewall 233. In another example, a tank mat 234 is laid on a portion of the inner side wall 233. The tank liner plate 234 can prevent the tank from being damaged due to excessive stress during transportation, and can protect the tank.

FIG. 3 shows a schematic side view of a tank container according to an exemplary embodiment of the present application. As shown in the embodiment of fig. 3, the tank container may include a tank body 10 and a frame 20 for receiving and supporting the tank body 10. The frame 20 may include a front end frame 2A, a rear end frame 2B, and a bottom frame 3 connected between the front and rear end frames 2A, 2B. Both ends of the can body 10 pass through the front end frame 2A and the rear end frame 2B, respectively, and the can body 10 is accommodated in a space surrounded by the front end frame 2A, the rear end frame 2B, and the bottom frame 3.

In one example, the front and back end bells 2A, 2B may each be an end bell 2 as described above. In another example, both or one of the front and back end bells 2A, 2B are different from the end bell 2 described above. Figure 4 shows a bottom frame 3 according to an exemplary embodiment.

As shown in the embodiment of fig. 3 and 4, the underframe 3 includes two bottom side members 31 connected between the end sills 22A, 22B of the front and rear end sills 2A, 2B. The bottom side member 31 may be an i-beam or a square tube structure. In the embodiment of fig. 3 and 4, the two bottom side beams 31 are shown as being generally parallel, it being understood that they could also be angled. In the embodiment of fig. 3 and 4, the two bottom side members 31 are each shown with both ends connected to both ends of the end sill 22, it being understood that both ends thereof may be connected to non-end positions of the end sill 22, respectively, or may be connected to non-end positions of the corner posts 21.

As shown in the embodiment of fig. 3 and 4, a side brace 32 may be further provided between the bottom side member 31 and the corner post 21 connected thereto, and one end of the side brace 32 is connected to the corner post 21 and the other end is connected to the bottom side member 31, so that the corner post 21, the bottom side member 31 and the side brace 32 together form a triangular structure for enhancing the structural stability of the frame 20. In one embodiment, a bottom sprag is connected to a middle portion of a web of an i-beam as the bottom side member to prevent torsion of the i-beam and facilitate load transfer. Alternatively, the side braces 32 may be replaced with a triangular box 34 connected between the corner posts 21 and the bottom side beams 31 to also serve as a stabilizing structure.

Similarly, as shown in the embodiment of fig. 3, a bottom brace 33 may be disposed between the bottom side beam 31 and the connected end lower beam 22A, 22B, one end of the bottom brace 33 is connected to the end lower beam 22A or 22B, and the other end is connected to the bottom side beam 31, so that the end lower beam 22A or 22B, the bottom side beam 31 and the bottom brace 33 form a triangular structure together for enhancing the structural stability of the bottom frame 3. Alternatively, the bottom sprags 33 may be replaced with triangular boxes 34 connected between the end lower beams 22A, 22B and the bottom side beam 31 to also function as a stabilizing structure.

Similarly, the triangular box 34 may be replaced with the side sprags 32 or the bottom sprags 33.

And the inclined strut structure or the triangular box is arranged between the bottom side beam of the bottom frame and the end lower beam of the end frame and between the bottom side beam of the bottom frame and the corner post of the end frame, so that the structural stability of the frame is enhanced, and the possibility of failure caused by fatigue is reduced.

With the embodiments described above, the tank container can achieve a capacity of up to 39T in total weight. In the embodiments described above, the tank container may be a Swap baby tank container, and may be other types of tank containers.
