AI Technical Summary
When using steel flooring, the strength of the gooseneck section of the existing container frame is insufficient, especially when the structure is poorly designed.
A support frame is formed by supporting longitudinal beams and supporting transverse beams, which is placed on the lower surface of the steel floor to distribute the downward pressure of the steel floor and increase the overall strength between the gooseneck longitudinal beams and the bottom side beams.
The strength of the gooseneck groove section on the underframe was improved, enhancing the overall structural stability of the container underframe and reducing its weight.

Abstract
Claims
1. Chassis, characterized in that It includes two bottom side beams extending longitudinally along the base frame, two gooseneck longitudinal beams, and a steel floor located at the top of the base frame. The top surfaces of the two gooseneck longitudinal beams are welded and fixed to the lower surface of the steel floor. The two gooseneck longitudinal beams extend longitudinally along the base frame and are staggered from each other in the width direction of the base frame. Multiple support beams are provided on the lower surface of the steel floor. The upper surfaces of the multiple support beams are welded and fixed to the lower surface of the steel floor. The lower surfaces of the multiple support beams and the opposite sides of the two gooseneck longitudinal beams together form a gooseneck groove. Multiple support beams and at least one support longitudinal beam are installed between the bottom side beam and the gooseneck longitudinal beam adjacent to the bottom side beam. The top surfaces of the support beams and the support longitudinal beams are welded and fixed to the lower surface of the steel floor. The multiple support beams are arranged longitudinally along the base frame and their two ends are welded to the bottom side beam and the gooseneck longitudinal beam respectively. The support longitudinal beam extends longitudinally along the base frame and is fixedly connected to the multiple support beams.
2. The undercarriage of claim 1, wherein, The lower surface of the supporting crossbeam is offset downward by a distance d1 relative to the lower surface of the supporting longitudinal beam, where d1 ≥ 20 mm.
3. The undercarriage of claim 2, wherein, The supporting longitudinal beam includes multiple supporting longitudinal beam units that are broken by multiple supporting crossbeams. The two ends of the supporting longitudinal beam units are respectively welded to the opposite surfaces of two adjacent supporting crossbeams.
4. The undercarriage of claim 2, wherein, The supporting crossbeam has a notch that is recessed downward from its top surface. The supporting longitudinal beam is a one-piece structure, with the supporting longitudinal beam embedded in the notch and the periphery of the notch welded and fixed to the outer surface of the supporting longitudinal beam.
5. The undercarriage of claim 1, wherein, The lower surface of the supporting crossbeam is offset upward by a distance d2 relative to the lower surface of the supporting longitudinal beam, where d2≥0. The supporting crossbeam includes multiple supporting crossbeam units that are broken by the supporting longitudinal beam. The two ends of the supporting crossbeam unit are respectively welded between adjacent supporting longitudinal beams, or between the bottom side beam and the supporting longitudinal beam adjacent to the bottom side beam, or between the gooseneck longitudinal beam and the supporting longitudinal beam adjacent to the gooseneck longitudinal beam.
6. The undercarriage of claim 1, wherein, Multiple support beams extend laterally along the base frame, with both ends of the support beams fixedly connected to two gooseneck longitudinal beams.
7. The undercarriage of claim 1, wherein, Multiple support beams extend longitudinally along the base frame.
8. The undercarriage of claim 1, wherein, The support beams include multiple longitudinal support beams extending along the longitudinal direction of the underframe and multiple transverse support beams extending along the transverse direction of the underframe. The longitudinal support beam comprises multiple longitudinal support beam units that are interrupted by multiple transverse support beams, with each end of a longitudinal support beam unit welded and fixed to two adjacent transverse support beams; or The transverse support beam comprises multiple transverse support beam units that are broken by multiple longitudinal support beams. The two ends of the transverse support beam unit are welded and fixed to two adjacent longitudinal support beams, or to an adjacent longitudinal support beam and a gooseneck beam, or to an adjacent longitudinal support beam and a bottom side beam.
9. The undercarriage of claim 1, wherein, The gooseneck longitudinal beam includes two side walls and a bottom wall connected between the bottom of the two side walls. The top of the two side walls is welded and fixed to the lower surface of the steel floor. A top support plate extending along the length of the gooseneck longitudinal beam is welded and fixed between the two side walls. Multiple support vertical plates arranged along the length of the gooseneck longitudinal beam are provided between the top support plate and the bottom wall. The two sides of the support vertical plates are welded and fixed to the two side walls respectively. The top of the support vertical plate is welded to the top support plate and the bottom is welded to the bottom wall.
10. A container characterised in that, Includes the base frame as described in any one of claims 1-9.
