Description

Gondola car body with box-shaped structure center beam

technical field

The utility model belongs to the car body of a railway transport vehicle.

Background technique

The car body of the existing railway transport open car is composed of a chassis assembly, a side wall assembly and an end wall assembly. Among them, the center beam in the chassis assembly is generally made of hot-rolled B-shaped steel, which has a serious disadvantage; In the side wall assembly, the surface of the beam parallel to the length direction of the car body will accumulate ore or sundries during use, causing it to be severely corroded, which not only increases maintenance costs, but also affects the service life of the car body.

Contents of the invention

The purpose of this utility model is to provide a gondola car body with a box-shaped structure center beam in view of the above shortcomings, which has the characteristics of simple structure and can reduce the weight of the car body.

The utility model is realized in the following way: it is composed of an underframe assembly, a side wall assembly and an end wall assembly, wherein the underframe assembly includes a floor and a bottom beam composed of a middle beam, a large crossbeam and a corbel. The reason is that the middle sill is a box-shaped structure formed by welding the upper cover plate, the lower cover plate and the web plates on both sides.

The thicknesses of the lower cover plate and the side web are both gradually thickened from the middle to both ends.

Said lower cover plate and side web are composed of end cover plate, middle cover plate and end web plate and middle web plate respectively.

Said side wall assembly includes column, side wall panel, small side column and upper side beam, wherein, column and small side column are all positioned at the outer surface of side wall panel and arranged vertically, and upper side beam is positioned at column, side wall The upper end of the board and the small jamb.

The end wall assembly includes cross braces, end wall panels, small end columns and upper end beams, wherein at least one cross brace and the small end columns below the cross braces are located on the outer surface of the end wall panels, and the upper end beam is located on the end of the end wall. top of the wall.

The lower end of said side wall panel is arc-shaped.

Both the longitudinal section of the cross brace and the cross section of the small end column are variable section structures.

The utility model adopts a box-shaped center sill, and adopts sheets of different thicknesses according to the stress conditions of different parts, which can reduce the weight of the car body; adopts vertical columns and small side columns (that is, the entire side wall panel There is no beam parallel to the length direction of the car body), which can avoid the accumulation of ore and other sundries on its upper surface, thereby reducing the degree of local corrosion of the car body; the lower end of the side wall plate is an arc-shaped structure, that is, the side wall The arc-shaped transition connection between the board and the floor can avoid waste of resources or energy consumption caused by unloading of ores and other materials.

Detailed ways

Further illustrate the utility model below in conjunction with accompanying drawing and embodiment.

Embodiment: After the middle beam 2A is welded with the upper cover plate 3, the lower cover plate 4 and the web plates 5 on both sides to form a box-shaped structure, it is then welded with the large beam 2B and the corbel 2C to form the bottom beam 2, and the bottom beam 2 and the floor 1 Constitute the chassis assembly, wherein the upper cover plate 3 is a steel plate of equal thickness, the lower cover plate 4 and the side web plate 5 are respectively composed of the end cover plate 4A, the middle cover plate 4B, the end web plate 5A and the middle web plate 5B, and They are all steel plates that are gradually thickened from the middle to both ends. There are two side wall assemblies in total, which are composed of upright columns 6, side wall panels 7, small side columns 8, and upper side beams 9. Among them, upright columns 6 and small side beams The columns 8 are respectively bent and formed by press-shaped channel steel and rectangular steel pipes, and are located on the outer surface of the side wall panel 7 and arranged vertically. The side wall panel 7 and the outer surface of the column 6 are inclined at an inclination angle of about 7 degrees. Its lower end is arc-shaped, and the upper side beam 9 is formed by cold pressing of plates, and is located at the upper end of the column 6, side wall panel 7 and small side column 8. The end wall assembly consists of two pieces, consisting of a cross brace 10 and an end wall panel 11. , the small end column 12 and the upper end beam 13 are welded, wherein, two cross braces 10 and a small end column 12 located below the second cross brace 10 are all located on the outer surface of the end wall panel 11, and the longitudinal brace 10 Both the section and the cross section of the small end column 12 are variable-section structures, the upper end beam 13 is located at the upper end of the end wall panel 11, and the angle between the end wall panel 11 and the floor 1 is 90 degrees, and the chassis assembly, two pieces The side wall assembly and the two end wall assemblies are welded together to form the utility model.
