Example Embodiment

[0017] Embodiment one:

[0018] like Figure 1 ~ Figure 4 As shown, the beam load-bearing structure of the container drop hole car of the present invention is located at the two ends and the middle of the concave chassis of the car body, including the upper cover plate 1 and the grooved beam 2, and its key technology is to also include the angular bearing seat 3, the upper The cover plate 1 is folded and pressed into a wide U shape. The upper cover plate 1 includes the left elevation 1.3, the right elevation 1.1 and the bottom surface 1.2. The frame is connected into one and forms a box-shaped beam with a frame-shaped closed section; the angular bearing seat 3 is a corner-shaped hollow section steel casting, and the angular bearing seat 3 includes a vertical end and a horizontal end 3.3, and the vertical end is provided with an embedded opening 3.2.

Abstract

The invention relates to a special-purpose truck key structure for container transportation, in particular to a transverse beam bearing structure for a loading container well-hole wagon, which comprises an upper cover plate and a slot-type beam, and further comprises an angle-shaped bearing seat, wherein the upper cover plate is folded and pressed to be a wide U shape, the upper cover plate comprises a left vertical plane, a right vertical plane and a bottom surface, the bottom surface and the slot-type beam are fastened, installed and welded, the angle-shaped bearing seat is a break angle-shaped hollow section steel casting, the angle-shaped bearing seat comprises a vertical end and a horizontal end, and the vertical end is provided with an embedded mouth. The transverse beam bearing structure for the loading container well-hole wagon has the beneficial effects that the transverse beam bearing structure for the loading container well-hole wagon achieves to directly weld the two ends of a transverse beam structure and a side wall plate and a side column of a wagon depressed center underframe side wall structure with extremely strong vertical stiffness, enables wagon body stress distribution to tend to be uniform, and prevents stress concentration.

Description

Technical field: [0001] The invention relates to a key structure of a special freight car for container transportation, in particular to a crossbeam bearing structure of a container drop hole car. Background technique: [0002] At present, there is a double-deck container vehicle in China. The beam structure of the concave underframe is a welded structure composed of an upper cover plate and a lower cover plate of the beam. ; while the upper cover covers the connection welds between the lower cover and the side beams, and is welded together with the lower cover of the beam and the two lower side beams. The beam structure is directly transmitted to the lower side beam of the side wall, resulting in local stress concentration between the lower side beam of the side wall and the connection weld between the lower cover plate of the beam and the lower side beam, and at the same time causing fatigue damage of the structure leading to structural failure and destruction. The second...
