[0033] Typical embodiments that embody 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 changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0034] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0035] The present invention provides a tank container, comprising a tank body and a tank container frame. The tank container frame supports the tank body. For the convenience of description, the length direction of the tank container frame is defined as the axis direction of the tank body.

[0036] The present invention also provides a tank container frame, which is described in detail in the following embodiments.

[0037] First embodiment of tank container frame

[0038] See also Figure 1 and Figure 2 The tank container frame 1 mainly includes two end frames 11 arranged at intervals, a top side beam 12 connected between the two end frames 11, a top cross beam 13 and a walkway.

[0039] The two top and side beams 12 are arranged in parallel and spaced apart, and the top and side beams 12 extend along the length direction of the tank container frame 1 to connect the two end frames 11. Specifically, the side beams include a side beam body 121, a plurality of cross beam connectors and a plurality of reinforcement members 123.

[0040] The side beam body 121 extends along the length direction of the tank container frame 1. In this embodiment, the side beam body 121 is in the shape of a square tube. The side beam body 121 can be split, for example, the side beam body 121 is welded and connected by multiple sections of square steel pipes, or the side beam body 121 can be integrated. The form of the side beam body 121 is not limited here, and the side beam body 121 is connected between the two end frames 11.

[0041] A plurality of cross beam connectors are arranged at intervals on one side of the side beam body 121 along the length direction of the side beam body 121. In this embodiment, two cross beam connectors are arranged on one side of each side beam body 121, and the two cross beam connectors are located in the middle area of ​​the side beam body 121. In other embodiments, three cross beam connectors or four cross beam connectors may be arranged on one side of each side beam body 121, depending on actual needs.

[0042] Specifically, the cross beam connector includes an end plate 1221 and a side plate 1222. The end plate 1221 is connected to one side of the side beam body 121 and extends along the height direction of the tank container frame 1. Specifically, the bottom of the end plate 1221 exceeds the side beam body 121 downward.

[0043] The side plate 1222 is connected to the bottom end of the end plate 1221 and extends along the width direction of the tank container frame 1, and the side plate 1222 and the side beam body 121 are arranged on opposite sides of the end plate 1221. The bottom of the end plate 1221 extends downwardly beyond the side beam body 121, so that along the height direction of the tank container frame 1, the side plate 1222 is lower than the side beam body 121.

[0044] The side plate 1222 is provided with a cross beam connection hole, and the axis of the cross beam connection hole extends along the height direction of the tank container frame 1. In this embodiment, two cross beam connection holes are provided on the side plate 1222, and the center line of the two cross beam connection holes is parallel to the side beam body 121. In other embodiments, the number of cross beam connection holes can also be three, four or other numbers. The multiple cross beam connection holes can be arranged in a straight line, in multiple horizontal and vertical rows, in a circular arrangement or in other arrangements.

[0045] The reinforcement member 123 is arranged in a one-to-one correspondence with the cross beam connector. The reinforcement member 123 is connected between the end plate 1221 and the side plate 1222, which increases the connection strength between the end plate 1221 and the side plate 1222, that is, increases the connection strength of the cross beam connector. Specifically, the reinforcement member 123 includes two vertically connected baffles and a cover plate connecting the two baffles, the two baffles and the cover plate are enclosed to form a box body, and one of the baffles is located above the end plate 1221 and is closely connected to the end plate 1221, and the other baffle is located on the side of the side plate 1222 and is closely connected to the side plate 1222.

[0046] A plurality of top cross beams 13 are arranged at intervals along the length direction of the top side beam 12. Specifically, the top cross beams 13 are arranged corresponding to the cross beam connectors. In this embodiment, the number of the top cross beams 13 is two.

[0047] See also Figure 3 The top cross beam 13 includes a cross beam body 131, transverse mounting members 132 connected to both ends of the cross beam body 131, longitudinal mounting members and reinforcement members 134. The cross beam body 131 extends along the width direction of the tank container frame 1, and the top and bottom of the cross beam body 131 are flush. In this embodiment, the cross beam body is an integrated type.

[0048] In the traditional multi-stage stepped top crossbeam, three sections of top crossbeam are connected in a stepped manner, and there is a height difference between two adjacent top crossbeam sections. The lower top crossbeam section is easy to interfere with the insulation layer of the tank body. Cutting the insulation layer to avoid interference not only increases waste and pollutes the working environment, but also reduces the insulation effect of the tank container. In this embodiment, an integrated crossbeam body is used to simplify the structure of the top crossbeam, and the top and bottom of the crossbeam body are flush, and there is no height difference. Therefore, the space at the top of the tank container frame is increased, the problem of the top crossbeam interfering with the insulation layer of the tank body is improved, the amount of cutting of the insulation layer is reduced, and the waste generation is reduced, thereby improving the insulation performance of the tank container.

[0049] The transverse mounting member 132 is disposed at the end of the beam body 131. Specifically, the transverse mounting member 132 includes a vertical plate 1321 and a horizontal plate 1322 that are vertically connected.

[0050] The vertical plate 1321 is connected to the end of the cross beam body 131 and extends downward along the height direction of the tank container frame 1 and extends downward beyond the cross beam body 131 .

[0051] Along the length direction of the tank container frame 1, both ends of the vertical plate 1321 extend beyond the cross beam body 131. The vertical plate 1321 is provided with a transverse mounting hole, and the axis of the transverse mounting hole extends along the width direction of the tank container frame 1. In this embodiment, the number of the transverse mounting holes is two, and the two transverse mounting holes are respectively located at the two ends of the vertical plate 1321. The transverse mounting holes are located on the portion of the vertical plate 1321 that extends beyond the cross beam body 131. In other embodiments, the number of the transverse mounting holes can also be four, six, or other numbers.

[0052] The horizontal plate 1322 is connected to the bottom end of the web 1422 and extends along the width direction of the tank container frame 1, and the horizontal plate 1322 and the cross beam body 131 are arranged on both sides of the web 1422. The bottom of the vertical plate 1321 extends downward beyond the cross beam body 131, so the horizontal plate 1322 is lower than the cross beam body 131.

[0053] Two horizontal mounting holes are provided on the horizontal plate 1322, which are arranged corresponding to the two beam connection holes. The axes of the two beam mounting holes extend along the height direction of the tank container frame 1. In other embodiments, the beam mounting holes can be arranged corresponding to the number and arrangement of the beam connection holes.

[0054] The longitudinal mounting members are arranged in pairs on both sides of the cross beam body 131, and the paired longitudinal mounting members are symmetrical about the cross beam body 131, and the paired longitudinal mounting members are opposite to each other along the length direction of the tank container frame 1. In this embodiment, along the width direction of the tank container frame 1, two pairs of paired longitudinal mounting members are spaced apart and connected on the cross beam body 131, and the two pairs of paired longitudinal mounting members are arranged corresponding to the two walkways.

[0055] Specifically, the longitudinal mounting member includes a vertically connected first mounting plate 1331 and a second mounting plate 1332. The first mounting plate 1331 is connected to one side of the crossbeam body 131, and the first mounting plate 1331 extends along the height direction of the tank container frame 1. The first mounting plate 1331 extends downward beyond the crossbeam body 131.

[0056] The second mounting plate 1332 is connected to the bottom end of the first mounting plate 1331 and extends along the width direction of the tank container frame 1. The second mounting plate 1332 and the crossbeam body 131 are respectively located on both sides of the first mounting plate 1331. A longitudinal mounting hole is provided on the second mounting plate 1332, and the axis of the longitudinal mounting hole extends along the height direction of the tank container frame 1.

[0057] The reinforcement member 134 is connected between the web 1422 and the beam body 131, and increases the connection strength between the web 1422 and the beam body 131, that is, increases the connection strength between the beam mounting member and the beam body 131. Specifically, the reinforcement member 134 is connected below the beam body 131. The reinforcement member 134 includes two vertically connected baffles and a cover plate connecting the two baffles, and the two baffles and the cover plate are enclosed to form a box body, wherein one baffle is connected to the web 1422, and the other baffle is connected to the beam body 131.

[0058] When the top cross beam 13 is assembled with the top side beam 12, the top cross beam 13 is located inside the top side beam 12, and the transverse mounting members 132 at both ends of the top cross beam 13 correspond to the cross beam connectors of the two top side beams 12. The horizontal plate 1322 of the transverse mounting member 132 is overlapped on the side plate 1222 of the cross beam connector, and the fasteners are passed through the cross beam mounting holes and the cross beam connecting holes, thereby realizing the detachable connection between the top cross beam 13 and the top side beam 12.

[0059] Among them, the fasteners include bolts and nuts. When assembly is required, just insert the bolts into the mounting holes and the connecting holes and screw on the nuts; when disassembly is required, unscrew the nuts and take out the bolts.

[0060] A plurality of top cross beams 13 are connected between the two top side beams 12, which increases the connection strength between the two top side beams 12. The top cross beam 13 and the top side beam 12 are detachably connected, which is more convenient for assembly between the top cross beam 13 and the top side beam 12 than welding connection, and reduces welding work.

[0061] The walkway extends along the length direction of the tank container frame 1. In this embodiment, the two walkways are arranged in parallel and spaced apart, and are arranged one by one with the two top side beams 12. The walkway is arranged on the inner side of the top side beam 12. In the width direction of the tank container frame 1, the direction in which the two top side beams 12 face each other is the inner side, and the direction in which the two top side beams 12 depart from each other is the outer side. Unless otherwise specified below, the definitions of the inner side and the outer side are consistent with those herein.

[0062] The walkway includes a plurality of walkway segments 14 connected along the length direction of the top side beam 12. Each walkway segment 14 extends along the length direction of the top side beam 12. A top cross beam 13 is connected between two adjacent walkway segments 14, and the walkway segments 14 are installed on the top of the tank container frame 1 through the top cross beam 13.

The web 1422 connects the top plate 1421 and the bottom plate 1423 , and the top plate 1421 and the bottom plate 1423 are located on the same side of the web 1422 .

[0065] One end of the top plate 1421 is connected to the end of the walkway body 141 and extends along the width direction of the tank container frame 1. A plurality of vertical connection holes are provided on the top plate 1421, and the axes of the vertical connection holes extend along the height direction of the tank container frame 1. The plurality of vertical connection holes are arranged at intervals along the length direction of the tank container frame 1.

[0066] The top end of the web 1422 is connected to the other end of the top plate 1421 and extends along the height direction of the tank container frame 1. The web 1422 is provided with a plurality of transverse connection holes, and the axes of the transverse connection holes extend along the width direction of the tank container frame 1. The plurality of transverse connection holes are arranged at intervals along the length direction of the tank container frame 1.

[0067] The bottom plate 1423 is connected to the bottom end of the web plate 1422 and extends along the width direction of the tank container frame 1. A plurality of vertical connection holes are provided on the bottom plate 1423, and the axes of the vertical connection holes extend along the height direction of the tank container frame 1. The plurality of vertical connection holes are arranged at intervals along the length direction of the tank container frame 1. The vertical connection holes on the bottom plate 1423 and the vertical connection holes on the top plate 1421 are located in the same vertical plane, that is, a fastener is simultaneously passed through the vertical connection holes of the bottom plate 1423 and the vertical connection holes of the top plate 1421.

[0068] The trail connector 142 located on the outside is the outside trail connector 142, and the trail connector 142 located on the inside is the inside trail connector 142. The trail segment 14 is connected to the transverse mounting member 132 of the top crossbeam 13 through the outside trail connector 142, and the inside trail connector 142 is connected to the longitudinal mounting member of the top crossbeam 13, so that the trail segment 14 is connected to the top crossbeam 13.

[0069] Specifically, when the trail segment 14 is installed with the top crossbeam 13, the top of the trail board is slightly lower than the top of the top crossbeam 13, the web 1422 of the outer trail connector 142 fits with the vertical plate 1321 of the transverse mounting member 132, the transverse connecting holes on the web 1422 are opposite to the transverse mounting holes on the vertical plate 1321, and fasteners pass through the transverse connecting holes and the transverse mounting holes to achieve a detachable connection between the outer trail connector 142 and the transverse mounting member 132.

[0071] Among them, the fasteners include bolts and nuts. When assembly is required, just insert the bolts into the mounting holes and the connecting holes and screw on the nuts; when disassembly is required, unscrew the nuts and take out the bolts.

[0072] There are connections between the top cross beam 13 and the walkway segment 14 in two directions at the same time, extending along the width direction of the tank container frame 1 and extending along the height direction of the tank container frame 1 respectively, and the stress on the top cross beam 13 and the walkway segment 14 can be dispersed in two directions, reducing stress concentration and increasing the connection strength between the two.

[0073] The detachable connection is achieved through the walkway connector 142 of the walkway segment 14 and the transverse mounting member 132 of the top crossbeam 13 and the walkway mounting member. Compared with the welding connection, the detachable connection is more convenient for the installation of the walkway and reduces the welding work.

[0074] One side of the top crossbeam 13 is connected to a walkway segment 14, and the other side is connected to another walkway segment 14, so that the walkway segments 14 are connected along the length direction of the tank container. The top crossbeam 13 is connected to the top side beam 12 to realize the installation of the entire walkway.

[0081] The web 2221 is provided with a cross beam connection hole, and the axis of the cross beam connection hole extends along the height direction of the tank container frame 2. In this embodiment, the web 2221 is provided with two cross beam connection holes, and the center line of the two cross beam connection holes is parallel to the side beam body 221. In other embodiments, the number of cross beam connection holes can also be three, four or other numbers. The multiple cross beam connection holes can be arranged in a straight line, in multiple horizontal and vertical rows, in a circular arrangement or in other arrangements.

[0082] See also Figure 8 and Fig. 9 The top cross beam 23 includes a cross beam body 231 , a transverse mounting member 232 , a longitudinal mounting member 233 and a cross beam mounting member 234 .

[0083] The cross beam body 231 extends along the width direction of the tank container frame 2, and the top and bottom of the cross beam body 231 are flush. In this embodiment, the cross beam body 231 is an integrated structure, which simplifies the structure of the top cross beam 23.

[0084] The transverse mounting members 232 are arranged in pairs on both sides of the end of the top cross beam 23. Specifically, the transverse mounting members 232 include a transverse plate 2321 and a longitudinal plate 2322 which are vertically connected to each other, the transverse plate 2321 extending along the width direction of the tank container frame 2 and closely attached to the side of the cross beam body 231, and the longitudinal plate 2322 protrudes from the transverse plate 2321 and extends along the length direction of the tank container frame, and the longitudinal plate 2322 constitutes a protruding portion.

[0085] When the top cross beam 23 is connected to the walkway 24 , the longitudinal plate 2322 of the transverse mounting member 232 fits with the web of the walkway connector, and the fasteners penetrate the transverse mounting holes and the transverse connecting holes to realize the detachable connection between the top cross beam 23 and one side of the walkway 24 .

[0086] The protruding portion has a transverse mounting hole, and the axis of the transverse mounting hole extends along the height direction of the tank container frame 2. In this embodiment, each protruding portion has one transverse mounting hole. In other embodiments, each protruding portion may also be provided with two, three or other numbers of transverse mounting holes.

[0087] The structure of the longitudinal mounting member 233 is the same as that of the first embodiment, and includes a vertically connected first mounting plate 2331 and a second mounting plate 2332. The details will not be described here, and reference may be made to the description in the first embodiment.

[0088] The cross beam mounting member 234 is disposed at the end of the cross beam body 231 , and along the length direction of the tank container frame 2 , the cross beam mounting member 234 does not cover the protruding portion of the transverse mounting member 232 and the protruding portion is exposed.

[0089] The crossbeam mounting member 234 specifically includes an end plate 2341 and a horizontal plate 2342 which are vertically connected to each other. The end plate 2341 is connected to the end of the crossbeam body 231 and extends along the height direction of the tank container frame 2 , and the horizontal plate 2342 is connected to the bottom of the end plate 2341 .

[0090] A crossbeam mounting hole is provided on the horizontal plate 2342 , and the axis of the crossbeam mounting hole extends along the height direction of the tank container frame 2 .

[0091] When the top cross beam 23 is connected to the top side beam 22, the horizontal plate 2342 of the cross beam mounting member 234 overlaps the web 2221 of the cross beam connecting member 222, and the fasteners pass through the cross beam mounting holes and the cross beam connecting holes, so that the two ends of the top cross beam 23 are detachably connected to the two top side beams 22.

[0092] It can be seen from the above technical solution that the advantages and positive effects of the present invention are:

[0093] The tank container frame of the present invention includes two top side beams, a walkway and a plurality of top cross beams connected between the two top side beams. The walkway includes a plurality of walkway segments connected along the length direction of the side beams, the two ends of the top cross beam are respectively connected to the two top side beams, and the two sides of the top cross beam are respectively connected to the two walkway segments; the connection between the top cross beam and the walkway is achieved by detachably connecting the transverse mounting piece of the top cross beam with the walkway connecting piece on one side of the walkway, and detachably connecting the longitudinal mounting piece with the walkway connecting piece on the other side of the walkway. The top cross beam in the tank container frame of the present invention has a simple structure, reduces welding operations, and is convenient for installing the walkway. Furthermore, there are connections in two directions between the top cross beam and each walkway segment, which are respectively extending along the width direction of the tank body and extending along the height direction of the tank body, and the stress on the top cross beam and the walkway can be dispersed in two directions, which reduces stress concentration and increases the connection strength between the two.
