As shown in fig. 1, a first aspect of the present utility model discloses a container chassis 100. The container chassis 100 includes bottom side beams 103. The bottom side members 103 extend in the longitudinal direction of the container chassis 100, and two bottom side members 103 parallel to each other are arranged at intervals in the width direction of the container chassis 100. The container chassis 100 includes a first bottom diagonal reinforcement beam 110. Both ends of the first bottom slope reinforcement beam 110 are connected to the two bottom side beams 103, respectively, and are inclined to the width direction. At least two first bottom diagonal reinforcement beams 110 are arranged in a V-shape.

According to the utility model, the first bottom diagonal reinforcement beams 110 arranged in a V shape are formed into a truss structure on the container chassis 100, so that when the container chassis 100 is affected by acceleration, load can be transferred on the container chassis 100 and transferred to the bottom side beams 103 through the first bottom diagonal reinforcement beams 110, thereby dispersing the stress of the container chassis 100, avoiding deformation and prolonging the service life of the container chassis 100.

The bottom side beam 103 may be C-steel, square tube or i-steel. The first bottom diagonal reinforcement beam 110 may be i-steel or square.

Preferably, the container chassis 100 includes at least three first bottom diagonal reinforcement beams 110 to be arranged in an opposite and continuous V-shape such that the intersections of adjacent first bottom diagonal reinforcement beams 110 are located on the bottom side beams 103 on both sides, respectively. Thus, the applied load can be transferred to the bottom side members 103 on both sides, respectively, and the load applied to the container chassis 100 can be more dispersed.

The distance between the junction of the two first bottom diagonal reinforcement beams 110 meeting at the bottom side beam 103 and the bottom side beam 103 is 40-60mm, so that the mechanical effect is better and the load transmission effect is better.

The container chassis 100 further includes bottom end beams 104, side sill beams 105, a first bottom cross beam 107, and a second bottom cross beam 108. The bottom end beams 104 extend in the width direction, and two bottom end beams 104 parallel to each other are arranged at intervals in the length direction. The side sill 105 extends in the longitudinal direction, and both ends of the side sill 105 are connected to the bottom end beams 104 at both ends, respectively. The side sill 105 may be i-steel or square tubing to ensure adequate rigidity. The lower surface of the side sill 105 is provided with a load transmitting block 106 for contacting the vehicle to transmit the weight of the cargo. The plurality of load transmission blocks 106 are arranged at intervals in the longitudinal direction. The first bottom cross member 107 extends in the width direction, both ends of the first bottom cross member 107 are connected to the bottom side members 103 on both sides, respectively, and a plurality of the first bottom cross members 107 are arranged at intervals in the length direction. The second floor rail 108 extends in the width direction, both ends of the second floor rail 108 are connected to the floor side members 103 on both sides, respectively, and a plurality of the second floor rails 108 are disposed at intervals in the length direction and spaced apart from the first floor rail 107. The first bottom rail 107 has a height that is greater than the height of the second bottom rail 108, i.e. the first bottom rail 107 is a stiffening bottom rail. The first bottom beam 107 and the second bottom beam 108 may each be C-shaped steel or square tubes.

The first bottom cross beam 107 is provided at the junction of the adjacent first bottom diagonal reinforcement beams 110, whereby the strength of the container chassis 100 can be further increased.

The second bottom rail 108 is connected to the upper surface of the first bottom diagonal reinforcement beam 110, for example, the second bottom rail 108 may be welded to the upper surface of the first bottom diagonal reinforcement beam 110 such that an applied load may be transferred to the second bottom rail 108.

The first bottom slope reinforcement beam 110 includes at least two short beams that are respectively connected to the bottom side rails 105. In other words, the side sill 105 extends through the first bottom diagonal reinforcement beam 110 and divides the first bottom diagonal reinforcement beam 110 into a plurality of short beams, which are welded to the side sill 105 may transfer loads to the side sill 105, further increasing the structural strength of the container chassis 100. In the illustrated embodiment, the container chassis 100 includes two side sills 105 that are parallel to each other, so the first bottom diagonal reinforcement beam 110 includes three short beams.

The container chassis 100 further includes a lifting foot 122 extending in a width direction, and the two lifting foot 122 are spaced apart in a length direction. The lifting foot beam 122 may be i-steel. The container chassis 100 comprises a middle portion 102 between two lifting bottom beams 122 and two end portions 101 outside the two lifting bottom beams 122. Depending on the centre of mass of the load, the position of the two lifting foot beams 122 may be adjusted so that the lengths of the two end portions 101 are the same or different. For example, in one embodiment, the two ends 101 are configured in an asymmetric arrangement, i.e., different lengths. In another embodiment, the two ends 101 are symmetrically arranged, i.e. of the same length.

Since the middle portion 102 of the container chassis 100 is most easily deformed, the first bottom diagonal reinforcement beam 110 is provided at the middle portion 102 to better transmit load and prevent deformation.

The container chassis 100 also includes a second bottom diagonal reinforcement beam 130. Both ends of the second bottom slope reinforcement beam 130 are connected to the bottom side beams 103 of both sides, respectively, and are inclined to the width direction. A second bottom diagonal reinforcement beam 130 is provided at the end 101. The second bottom diagonal reinforcement beam 130 is connected at one end to the lifting foot beam 122 and at the other end to the foot beam 104 or the first bottom cross beam 107. In other words, the second bottom diagonal reinforcement beam 130 is connected at one end to the bottom side rail 103 and the lifting bottom rail 122, at the other end to the bottom side rail 103 and the bottom end rail 104 on the other side (see the second bottom diagonal reinforcement beam 130 on the left side of fig. 1), or at the other end to the bottom side rail 103 and the first bottom cross rail 107 on the other side (see the second bottom diagonal reinforcement beam 130 on the right side of fig. 1). By providing the second bottom diagonal reinforcement beam 130 at the end 101, the load can thereby be transferred to the lifting bottom beam 122 and the bottom end beam 104 or the first bottom cross beam 107, avoiding deformation of the container chassis 100 due to concentrated stress. Preferably, in the illustrated embodiment, at least two second bottom diagonal reinforcement beams 130 are disposed to intersect, so that the load transfer effect is better.

As shown in fig. 2 and 3, the container chassis 100 further includes a support assembly 150 for carrying cargo. At least two support members 150 are spaced apart in the length direction. In one embodiment, as shown in fig. 2, the support assembly 150 is provided to the lifting foot beams 122 and/or the first bottom cross beams 107, i.e. the support assembly 150 is fixedly provided with respect to the container chassis 100, whereby the weight of the cargo can be dispersed to the lifting foot beams 122 and/or the first bottom cross beams 107 with higher strength, avoiding damage to the container chassis 100. In another embodiment, as shown in fig. 3, the container chassis 100 further includes a rail 210. The guide rails 210 extend in the longitudinal direction and are provided to the side sills 105, for example, two guide rails 210 are respectively connected to the upper surfaces of the two side sills 105. The support assemblies 150 are slidably disposed to the rails 210, i.e., the support assemblies 150 are slidably disposed with respect to the container chassis 100. Therefore, the position of the supporting component 150 can be adjusted according to different loaded cargos, so that the container chassis 100 is suitable for various cargos, the applicability is improved, the cargos can be dispersed to the side sill 105 with higher strength, and the damage of the container chassis 100 is avoided.

In a second aspect, the utility model discloses a container for carrying a cylindrical object such as a rocket body. The container comprises the container underframe. The container is constructed as a generally rectangular parallelepiped frame having a length of 45-50m, a width of 5-7m, and a height of 2-4m.
