[0035] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0036] This embodiment provides an intermodal tank container. By improving the frame structure, its strength is increased to meet the standards of Chinese railway transportation. Furthermore, if it meets domestic standards, it can fully meet the technical requirements of international intermodal transportation. Therefore, developing an LNG tank container frame suitable for Chinese railway transportation overcomes the technical limitations of Chinese railway transportation, fully realizing global intermodal transport of tank containers via road, rail, and water.

[0037] Please refer to the above as well. Figure 1 and Figure 2 This illustrates the specific structure of an intermodal tank container provided in this embodiment, which includes a frame 100 and a tank 200 horizontally installed inside the frame 100.

[0038] The frame 100 includes two end frames 1 that are respectively connected to the longitudinal ends of the tank 200. Figure 1 Taking the view direction as reference, one end frame 1 located at the front end of the tank 200 is called front end frame 1a, and the other located at the rear end of the tank 200 is called rear end frame 1b. Front end frame 1a and rear end frame 1b are respectively welded and fixed to the ends of the tank 200 by connecting rings.

[0039] The frame 100 also includes two sets of support seats 2 and multiple reinforcing members 3, all located at the bottom of the tank body 200.

[0040] Two sets of support seats 2 are longitudinally spaced at both ends of the tank body 200, and each set has two support seats 2 spaced laterally along the tank body 200.

[0041] The support base 2 is a hollow shell with an opening 201 communicating with the interior of the shell, the opening 201 facing upwards; the support base 2 is located at the periphery of the opening 201 and is connected and fixed to the bottom of the tank body 200. Each support base 2 extends longitudinally, and one end of the support base 2 along the longitudinal direction is connected to the end frame 1; the reinforcing member 3 is received inside the support base 2 through the opening 201, and the reinforcing member 3 is connected and fixed to the inner wall of the support base 2 and the bottom of the tank body 200 respectively, thereby strengthening the support base 2, increasing its impact resistance, and meeting domestic railway transportation standards.

[0042] It should be noted that the cross-section of the traditional support is roughly V-shaped, so support 2 is also known in the industry as a V-beam.

[0043] Please refer to the above as well. Figure 3 and Figure 4 One of the support seats 2 located at the bottom of the front end of the tank 200 is the front support seat 2a.

[0044] The front support 2a adopts a semi-disconnected gooseneck groove, which connects the front frame 1a and the bottom of the tank 200 longitudinally. A reinforcing member 3 is set inside the connection between the front support 2a and the tank 200. While reducing its own weight, the front support 2a has sufficient strength and rigidity, and at the same time, it effectively transfers and distributes the load of the tank 200 as a load transfer area.

[0045] The front support 2a includes a base plate 21, two side plates 24 formed by bending the two ends of the base plate 21 laterally to the same side, and two sealing plates 25.

[0046] The bottom plate 21 is a long, flat plate structure, with its length aligned with the longitudinal direction of the tank body 200. The bottom plate 21 is horizontal and spaced below the bottom of the tank body 200. Two side plates 24 are located on either side of the bottom plate 21 in the width direction. The side plates 24 are connected to the bottom plate 21 approximately perpendicularly. Both side plates 24 are connected upwards to the bottom of the tank body 200. One end of the side plate 24 along the longitudinal direction is connected forward to the front end frame 1a, and the end of the side plate 24 furthest from the end frame 1 is a free end 23.

[0047] The free end 23 extends further rearward along the longitudinal direction and beyond the bottom plate 21. Its purpose is to extend the longitudinal length of the side plate 24, increasing the connection area between the side plate 24 and the bottom of the tank body 200, thus improving the connection strength. Furthermore, the lower edge of the side plate 24 is arc-shaped. This arc design reduces the weight of the side plate 24 without compromising strength, and the arc transition avoids stress concentration, ensuring service life.

[0048] Two sealing plates 25 are positioned opposite each other at both ends of the longitudinal direction of the base plate 21. The sealing plates 25 are vertical, and each sealing plate 25 is connected to the base plate 21 and the two side plates 24 respectively. The two sealing plates 25, the base plate 21, and the two side plates 24 together enclose a box-shaped shell with an opening 201. During installation, the upper end of the sealing plate 25 has an arc that adapts to the circumference of the tank body 200 so as to be welded and fixed to the bottom of the tank.

[0049] Furthermore, the cross-section of the front support 2a is an unusual, irregular shape.

[0050] like Figure 4 As shown, the two side plates 24 of the front support 2a are the first side plate 241 and the second side plate 242, respectively.

[0051] The first side plate 241 is vertical. The second side plate 242 is closer to the central axis of the tank 200 than the first side plate 241, and is located inside the first side plate 241.

[0052] The second side plate 242 includes a lower vertical plate 2421, a middle horizontal plate 2422, and an upper vertical plate 2423 connected in sequence in a stepped shape.

[0053] Both the lower vertical plate 2421 and the upper vertical plate 2423 are vertical, with the lower end of the lower vertical plate 2421 connected to the bottom plate 21. The middle horizontal plate 2422 is horizontal, with its two ends perpendicularly connected to the upper ends of the lower vertical plate 2421 and the lower ends of the upper vertical plate 2423, respectively. The upper end of the upper vertical plate 2423 is connected to the tank body 200. The upper vertical plate 2423 is further inward than the lower vertical plate 2421, thus forming a stepped structure with an opening 201 facing downward between the upper vertical plate 2423, the middle horizontal plate 2422, and the lower vertical plate 2421. The gap between the stepped structures of the two front support seats 2a forms a gooseneck groove 202, which is used to accommodate the gooseneck beam of the semi-trailer vehicle, increasing its applicability.

[0054] Please refer to this again. Figure 3 The corresponding reinforcing member 3 located inside the front support 2a is a flat plate structure.

[0055] The shape of the reinforcing member 3 is adapted to the cross-sectional profile of the front support 2a, and the side of the reinforcing member 3 facing the second side plate 242 is also stepped, thereby enabling a tight connection with the inner wall of the front support 2a and improving the connection strength. The upper end of the reinforcing member 3 has an arc adapted to the perimeter wall of the tank 200 for welding and fixing to the bottom of the tank. Each front support 2a has multiple reinforcing members 3 inside. The multiple reinforcing members 3 are arranged at intervals along the longitudinal direction of the tank 200 to ensure that the front support 2a has sufficient strength to support the tank 200.

[0056] The frame 100 also includes two bottom side beams 41, two top side beams 42, two front diagonal braces 51 and two front reinforcing cross braces 61.

[0057] Two bottom side beams 41 are arranged on the transverse sides of the tank body 200; the two ends of the bottom side beams 41 are respectively connected to the bottom of the two end frames 1.

[0058] The two top side beams 42 and the two bottom side beams 41 are vertically opposite each other, and the two ends of the top side beams 42 are respectively connected to the top of the two end frames 1.

[0059] Two front diagonal braces 51 are symmetrically arranged longitudinally and located on the outer side of the front support seat 2a. The front diagonal braces 51 are inclined relative to the longitudinal axis of the tank body 200, and the two front diagonal braces 51 gradually approach each other longitudinally from front to rear. One end of the front diagonal brace 51 is welded and fixed to the outer wall of the front support seat 2a (specifically, the first side plate 241), and the other end of the front diagonal brace 51 is welded and fixed to the inner side of the front end frame 1a. The front diagonal braces 51 can transfer the longitudinal load on the front support seat 2a to the front end frame 1a, improving the impact resistance of the tank. Furthermore, first reinforcing ribs 81 are provided between the front diagonal brace 51 and the bottom side beam 41, and between the front diagonal brace and the front support seat 2a, further improving the connection strength.

[0060] Two front reinforcing cross braces 61 are symmetrically arranged on the outer sides of the two front support seats 2a. The front reinforcing cross braces 61 extend laterally, and their two ends are connected to the front support seat 2a and the bottom side beam 41 respectively, effectively transferring and sharing the load of the tank body 200.

[0061] Please refer to the above as well. Figure 5 and Figure 6 One of the support seats 2 located at the bottom of the rear end of the tank 200 is the rear support seat 2b.

[0062] The rear support 2b is connected to the saddle 71 and the rear end frame 1b respectively, and is connected to the rear diagonal brace 52 through the reinforcing box 80 to form an integral whole, thereby effectively transferring the rear impact load to the saddle 71 and the tank 200.

[0063] The bottom of the tank body 200 is provided with multiple saddles 71 at longitudinal intervals.

[0064] Specifically, the rear support 2b includes a base plate 21 and two side plates 24 formed by bending from both ends of the base plate 21 laterally to the same side.

[0065] The bottom plate 21 is a long, flat plate structure, with its length aligned with the longitudinal direction of the tank body 200. The bottom plate 21 is horizontal and spaced below the bottom of the tank body 200. Two side plates 24 are located on either side of the bottom plate 21 in its width direction. The side plates 24 are connected to the bottom plate 21 approximately perpendicularly. Both side plates 24 are connected upwards to the bottom of the tank body 200. One end of the side plate 24 along its longitudinal direction is connected forward to the rear end frame 1b, and the end of the side plate 24 away from the rear end frame 1b is perpendicularly connected to the saddle 71.

[0066] like Figure 6 As shown, both side plates 24 are vertically extending flat plate structures, so the cross-section of the rear support 2b is approximately U-shaped.

[0067] The reinforcing member 3, correspondingly located inside the rear support 2b, has a shape adapted to the cross-sectional profile of the rear support 2b. The reinforcing member 3 can be tightly connected to the inner wall of the rear support 2b, improving the connection strength. The upper end of the reinforcing member 3 has an arc adapted to the perimeter wall of the tank 200 for welding and fixing to the bottom of the tank. Each rear support 2b has multiple reinforcing members 3 inside; these multiple reinforcing members 3 are arranged at intervals along the longitudinal direction of the tank 200, ensuring that the rear support 2b has sufficient strength to support the tank 200.

[0068] The frame 100 also includes two rear diagonal braces 52 and two reinforcing boxes 80.

[0069] Two rear diagonal braces 52 are symmetrically arranged longitudinally and located outside the two rear support seats 2b. The rear diagonal braces 52 are inclined relative to the longitudinal axis, and the two rear diagonal braces 52 gradually approach each other from back to front in the longitudinal direction. There is a certain gap between the rear diagonal braces 52 and the rear support seats 2b. One end of the rear diagonal brace 52 is welded and fixed to the rear end frame 1b, and the other end of the rear diagonal brace 52 is connected and fixed to the saddle 71, thereby transferring the longitudinal load on the rear support seat 2b to the rear end frame 1b and improving the impact resistance of the tank box.

[0070] Two reinforcing boxes 80 are symmetrically arranged along the longitudinal direction. Each reinforcing box 80 is sandwiched between the rear diagonal brace 52 and the rear support seat 2b.

[0071] The reinforcing box 80 is approximately wedge-shaped to fit the gap between the rear diagonal brace 52 and the rear support seat 2b.

[0072] The two lateral sidewalls of the reinforcing box 80 are tightly fitted to the sides of the rear diagonal brace 52 and the rear support seat 2b, respectively. Furthermore, one longitudinal end of the reinforcing box 80 is welded and fixed to the saddle seat 71, so that the rear support seat 2b is connected to the rear diagonal brace 52 through the reinforcing box 80 to form a whole, so that the tank box is evenly stressed and the overall structure is reliable.

[0073] In addition, the frame 100 also includes two second reinforcing ribs 82, two third reinforcing ribs 83 and two rear reinforcing cross braces 62 to reinforce the rear end of the frame 100 at multiple locations, thereby improving the strength and stability of the frame 100.

[0074] Two second reinforcing ribs 82 are symmetrically arranged along the longitudinal direction. The second reinforcing ribs 82 are triangular in shape and are connected to the bottom side beam 41 and the rear diagonal brace 52, respectively.

[0075] Two third reinforcing ribs 83 are symmetrically arranged along the longitudinal direction. The third reinforcing ribs 83 are triangular in shape and are located on the upper surface of the rear diagonal brace 52. The third reinforcing ribs 83 are respectively connected to the rear diagonal brace 52 and the saddle 71.

[0076] Two rear reinforcing cross braces 62 are symmetrically arranged at both ends of the saddle 71. The rear reinforcing cross braces 62 extend laterally, and their two ends are connected to the saddle 71 and the bottom side beam 41 respectively, effectively transmitting and distributing the load of the tank 200.

[0077] Please refer to Figure 7 The frame 100 also includes multiple bottom side beam cross braces 72.

[0078] Multiple bottom side beam cross braces 72 are spaced apart longitudinally. Each bottom side beam cross brace 72 extends laterally along the tank body 200, with its two ends connected to the inner sides of two bottom side beams 41 respectively. The bottom side beam cross braces 72 can effectively increase the rigidity of the bottom side beams 41. According to the stress analysis, combined with the simple saddle 71, the weight of the frame 100 can be reasonably reduced.

[0079] Furthermore, multiple support members 721 protrude from the upper surface of the bottom side beam cross brace 72. The support members 721 are fixed to the bottom of the tank 200 by welding with a pad, thereby supporting the tank 200 and further improving the stability of the connection.

[0080] In this embodiment, the components of the frame 100 are welded together from square tubes and corner pieces. Its bottom support and front and rear end frames 1b are connected as a whole, achieving a lightweight design while ensuring strength, simplifying manufacturing, and ensuring structural stability. This frame 100 structure can withstand tank container bolting or lifting operations. Under longitudinal impact or collision forces, the stress distribution at each part of the structure is reasonable, resulting in structural stability and reliability.

[0081] In summary, the intermodal tank container provided by this invention has at least the following advantages and positive effects:

[0082] This intermodal tank container improves overall strength and meets high-standard railway transportation requirements through structural improvements to the frame 100. Specifically, the frame 100 is equipped with two sets of longitudinally spaced support seats 2. Each support seat 2 is a hollow shell with an opening 201 connecting to the interior of the shell. The periphery of the support seat 2 at the opening 201 is connected to the bottom of the tank 200, thereby supporting the bottom of the tank 200 and bearing its weight, and transferring the longitudinal load to the end frame 1. A reinforcing member 3 is housed inside the support seat 2 through the opening 201. The reinforcing member 3 is connected and fixed to the inner wall of the support seat 2 and the bottom of the tank 200, respectively, to strengthen the support seat 2, increase its impact resistance, and enable the support seat 2, as a load transfer area, to effectively transfer and distribute the load of the tank 200.

[0083] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many 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. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
