[0002] This application claims priority to the Chinese patent application filed with the Patent Office of China on December 15, 2023, with application number CN202311738050.5 and invention name “Container chassis and container having the same”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present invention relates to the technical field of containers, and in particular to a container chassis and a container having the same. Background Art

[0004] The synthetic resin container is a dry bulk container that can transport synthetic resin bulk cargo. It has the characteristics of light weight, large volume, top loading and side unloading of cargo. After the hydraulic lifting frame is installed on the road transport vehicle, it is integrated with the container for use, and unloading can be completed without lifting equipment. It can be used for large-scale transportation and storage of synthetic resin bulk cargo, and can realize the safe, clean and efficient transportation of synthetic resin bulk cargo, with low comprehensive transportation cost and high economic benefits.

[0005] The key technology of synthetic resin containers is top loading and side unloading of goods. After the hydraulic lifting frame is installed on the road transport vehicle, it is integrated with the container for use. Synthetic resin bulk goods can be used for packaging and manufacturing of daily necessities. It is a petrochemical product with high economic value. With the development of society and the improvement of people's living standards, the demand for synthetic resin products is gradually increasing. In the current railway transportation of synthetic resin, a large amount of bagged flatbed cars and ton bag general boxes are used for transportation. A large amount of manpower is used to carry goods during transportation, and the transportation cost is high. In the transportation of ton bags, the ton bags are not used in a standardized manner, and the loss of goods is large.

[0006] In related technologies, synthetic resins, due to their granular structure and fluidity, require high structural strength for the underframe when transported in containers. Currently, the underframes of containers used to transport synthetic resins employ a standard structure, consisting of an outer frame and multiple crossbeams positioned within it. This structure is difficult to meet the requirements for transporting synthetic resins, and the crossbeams within the underframe are poorly arranged, making the underframe susceptible to damage.

DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] As shown in Figures 1, 4, and 5, in this embodiment, the container chassis includes a chassis portion 1, which includes a first side beam 11, a second side beam 12, multiple crossbeam groups 20, and multiple second crossbeams 30. The second side beam 12 is spaced apart from the first side beam 11. The multiple crossbeam groups 20 are spaced apart between the first side beam 11 and the second side beam 12, and each crossbeam group 20 includes multiple first crossbeams 21. At least one second crossbeam 30 is disposed between any two adjacent crossbeam groups 20. The height of the first crossbeam 21 is less than that of the second crossbeam 30.

[0033] Using the technical solution of this embodiment, the first side beam 11 and the second side beam 12 are spaced apart, and multiple cross-beam groups 20 are spaced apart between the first side beam 11 and the second side beam 12. Each cross-beam group 20 includes multiple first cross-beams 21. At least one second cross-beam 30 is located between any two adjacent cross-beam groups 20. Specifically, the height of the first cross-beam 21 is less than that of the second cross-beam 30. Through this arrangement, the multiple cross-beam groups 20 can connect the first side beam 11 and the second side beam 12 and ensure the structural strength of the chassis 1. Furthermore, since at least one second cross-beam 30 is located between any two adjacent cross-beam groups 20, and since the second cross-beam 30 is taller than the first cross-beam 21, the second cross-beam 30 has greater structural strength than the first cross-beam 21. The second cross-beam 30 is connected between the first side beam 11 and the second side beam 12, further improving the structural strength of the chassis 1. This arrangement improves the rationality of the chassis 1 layout, ensuring the structural strength of the chassis 1 while also preventing excessive weight. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the arrangement of the cross beams in the container chassis is not rational, which leads to the chassis being easily damaged.

[0034] It should be noted that, in this embodiment, multiple first beams 21 and multiple second beams 30 can take into account the load transfer situation while providing strength and rigidity for the base frame 1. The second beams 30 at the load transfer area are higher than the first beams 21. During the container transportation process, the base frame 1 is evenly stressed through the load transfer area, which makes the container more reasonably stressed, thereby enhancing the rationality of the structural design.

[0035] As shown in Figure 6, in this embodiment, the ratio of the height of the first crossbeam 21 to the height of the second crossbeam 30 is between 0.5 and 0.8. This ratio can achieve a balance between structural strength and weight reduction. Specifically, the ratio of the height of the first crossbeam 21 to the height of the second crossbeam 30 is 0.6.

[0036] As shown in FIG5 , in this embodiment, in the direction from the first end of the first side beam 11 to the second end of the first side beam 11 , the number of first cross beams 21 in at least some of the cross beam groups 20 in the plurality of cross beam groups 20 is different. The above arrangement can ensure structural strength.

[0037] As shown in Figures 5 and 6, in this embodiment, the top surface of the first crossbeam 21 is flush with the top surface of the second crossbeam 30. The above arrangement can make the upper surface of the chassis 1 flush, thereby making the plate body on the chassis 1 more flush.

[0038] As shown in Figures 4 and 5, in this embodiment, the plurality of cross-beam groups 20 include a first load-bearing group 22, a second load-bearing group 23, a third load-bearing group 24, a fourth load-bearing group 25, a fifth load-bearing group 26, and a sixth load-bearing group 27, which are arranged sequentially from the first end of the first side beam 11 to the second end of the first side beam 11. The number of first cross-beams 21 in the first load-bearing group 22 is greater than the number of first cross-beams 21 in the second load-bearing group 23, the number of first cross-beams 21 in the third load-bearing group 24 is equal to the number of first cross-beams 21 in the fourth load-bearing group 25, and the number of first cross-beams 21 gradually decreases from the fourth load-bearing group 25 to the sixth load-bearing group 27. This arrangement ensures structural strength. Specifically, the first load-bearing group 22 is located near the front of the vehicle, and the sixth load-bearing group 27 is located near the rear of the vehicle. The bearing capacity of the first bearing group 22 is greater than that of the second bearing group 23, the bearing capacities of the third bearing group 24 and the fourth bearing group 25 are the same, the bearing capacity of the fifth bearing group 26 is greater than that of the sixth bearing group 27, and the sum of the bearing capacities of the first bearing group 22 and the second bearing group 23 is greater than the bearing capacities of the fifth bearing group 26 and the sixth bearing group 27. This not only improves the overall structural strength of the base frame 1, but also ensures the stability of the transportation of synthetic resin.

[0039] As shown in Figures 4 and 5, in this embodiment, within the first load-bearing group 22, the distance between two adjacent first crossbeams 21 farther from the second crossbeam 30 is greater than or equal to the distance between two adjacent first crossbeams 21 closer to the second crossbeam 30. Within the third load-bearing group 24, the multiple distances between any two adjacent first crossbeams 21 in the direction from the first end of the first side beam 11 to the second end of the first side beam 11 first increase and then decrease. Within the fourth load-bearing group 25, the multiple distances between any two adjacent first crossbeams 21 in the direction from the first end of the first side beam 11 to the second end of the first side beam 11 first increase, then decrease, and finally increase again. This arrangement further improves the strength of the structure and reduces the overall weight.

[0040] As shown in Figures 4 and 5, in this embodiment, a second crossbeam 30 is provided between the first load-bearing group 22 and the second load-bearing group 23, two second crossbeams 30 are provided between the second load-bearing group 23 and the third load-bearing group 24, one second crossbeam 30 is provided between the third load-bearing group 24 and the fourth load-bearing group 25, two second crossbeams 30 are provided between the fourth load-bearing group 25 and the fifth load-bearing group 26, and two second crossbeams 30 are provided between the fifth load-bearing group 26 and the sixth load-bearing group 27. The above arrangement can further improve the structural strength of the chassis portion 1.

[0041] Specifically, as shown in Figure 4, in this embodiment, a first connecting beam is provided in the second load-bearing group 23, the first connecting beam is arranged parallel to the first side beam 11, and the distance a between the first connecting beam and the first side beam 11 and the distance b between the first connecting beam and the second side beam 12 satisfy: 1.3≤a / b≤4.

[0042] Similarly, a second connecting beam is provided within the fifth load-bearing group 26, parallel to the first side beam 11 and corresponding to the first connecting beam. The first and second connecting beams are each provided corresponding to a support assembly 40, thereby improving the structural strength of the portion where no support assembly 40 is provided.

[0043] As shown in FIG6 , in this embodiment, the first crossbeam 21 includes a first flat plate 211, a first upright plate 212, and a second flat plate 213. The first and second flat plates 211 and 213 are connected at opposite ends of the first upright plate 212 and are disposed opposite each other. A first opening is formed between the first and second flat plates 211, 213, and the first upright plate 212. The first and second flat plates 211 and 213 are of the same size. The second crossbeam 30 includes a third flat plate 31, a second upright plate 32, and a fourth flat plate 33. The third and fourth flat plates 31 and 33 are connected at opposite ends of the second upright plate 32 and are disposed opposite each other. A second opening is formed between the third and fourth flat plates 31, 33. The cross-sectional areas of the third and fourth flat plates 33 are equal. The first and second crossbeams 21 and 30 are simple in structure, easy to manufacture, and can provide the overall structural strength of the chassis portion 1 with good strength.

[0044] Specifically, a ratio of the width of the first flat plate 211 to the width of the third flat plate 31 is between 0.7 and 0.8, and a ratio of the thickness of the first flat plate 211 to the thickness of the third flat plate 31 is between 0.5 and 0.7.

[0045] As shown in Figures 5 and 6, in this embodiment, the first openings of the plurality of first crossbeams 21 are all oriented in the same direction. The second openings of the two second crossbeams 30 between the second load-bearing group 23 and the third load-bearing group 24 are oriented in opposite directions. The second openings of the two second crossbeams 30 between the fourth load-bearing group 25 and the fifth load-bearing group 26 are oriented in opposite directions. The second openings of the two second crossbeams 30 between the fifth load-bearing group 26 and the sixth load-bearing group 27 are oriented in opposite directions. The plurality of first openings are all oriented in the same direction, which simplifies the manufacture of the chassis 1 and reduces resistance when the container is moved on the vehicle body.

[0046] As shown in Figures 5 and 6, in this embodiment, the second opening directions of the two second beams 30 between the second bearing group 23 and the third bearing group 24 are opposite. A connecting seat can be set between the above-mentioned two second beams 30, and the connecting seat can cooperate with the end of the lifting structure.

[0047] As shown in Figures 1 to 4, in this embodiment, the container chassis also includes a plurality of support assemblies 40 arranged at intervals, and the plurality of support assemblies 40 are located above the chassis portion 1 and connected to the chassis portion 1, and each support assembly 40 includes a first main oblique beam 41, a second main oblique beam 42 and a third main oblique beam 43, and the first end of the first main oblique beam 41, the first end of the second main oblique beam 42 and the first end of the third main oblique beam 43 are connected, and the connection between the first end of the first main oblique beam 41, the first end of the second main oblique beam 42 and the first end of the third main oblique beam 43 is located directly above the first side beam 11, and the second end of the first main oblique beam 41 is connected to the middle of the chassis portion 1, and the second end of the second main oblique beam 42 and the second end of the third main oblique beam 43 are both connected to the first side beam 11, forming a triangular structure between the first side beam 11, the second main oblique beam 42 and the third main oblique beam 43. The setting of the support assembly 40 can make it easier for the goods in the container to flow out from the unloading port. At the same time, the setting of the first main oblique beam 41, the second main oblique beam 42 and the third main oblique beam 43 can ensure the structural strength of the support assembly 40.

At the same time, a support beam 46 is provided between the first main oblique beam 41 and the chassis portion 1, so that the support beam 46 can be connected to the chassis portion 1, thereby improving the structural design strength and having good practicality; and can realize the function of inclined unloading.

[0049] As shown in Figures 1 to 4, in this embodiment, the second end of the first main oblique beam 41 is connected to the first cross beam 21 or the second cross beam 30. The above arrangement can make the position of the first main oblique beam 41 more stable.

The arrangement of the first sub-slanted beams 44 and the second sub-slanted beams 45 can improve the structural strength of the support assembly 40.

[0051] Specifically, the plurality of first auxiliary oblique beams 44 are arranged in parallel with the second main oblique beam 42 , and the plurality of second auxiliary oblique beams 45 are arranged in parallel with the third main oblique beam 43 .

[0052] As shown in Figures 1 to 4, in this embodiment, each support assembly 40 further includes a support beam 46, a first end of which is connected to the first main oblique beam 41, and a second end of which is connected to the first side beam 11, the first cross beam 21, or the second cross beam 30. The provision of the support beam 46 can further improve the stability of the first main oblique beam 41, the second main oblique beam 42, and the third main oblique beam 43.
