Abstract
The invention provides a chassis of a railway bathtub open wagon, relating to a chassis on a railway bathtub open wagon, wherein the chassis provided by the invention is mainly used for solving the defects that the existing chassis cannot meet the use requirements of a macro-axis heavy-railway bathtub open wagon and the end plate of the bathtub is easy to deform and short in service life. The chassis in the invention comprises an end beam assembly, a longitudinal beam, a sleeper beam assembly, a side beam assembly, a bathtub composed of a bottom plate and an end plate, and a box-shaped traction beam composed of an upper cover plate, a web plate and a lower cover plate. The chassis is characterized in that both the tail end of the upper cover plate and the tail end of the web plate are welded with the end plate, wherein the tail end of the web plate is of a section-changing structure with a gradually enlarged section from the outside to the inside. The chassis has the advantages of simple structure, reduced weight of the traction beam, reduced longitudinal impact to the end plate of the bathtub and prolonged service life of the bathtub.
Description
Technical field
The present invention relates to railway bathtub open-top car, relate in particular to the underframe on the railway bathtub open-top car.
Background technology
The bathtub that existing railway bathtub open-top car underframe comprises end carriage assembly, longitudinal beam, sleeper beam assembly, curb girder assembly, be made of base plate and end plate, the box draw beam that constitutes by upper cover plate, web and lower cover, wherein, described web is the same big rectangular plates of two end sections, the tail end of described upper cover plate, web and lower cover all is welded to connect with the end plate of bathtub, and increases the gusset that tail end and bathtub end plate weld below web.Though this kind structure can satisfy the operating needs of existing railway bathtub open-top car, but for the heavy railway bathtub of macro-axis open-top car, because axle heavily increases, make the corresponding increase of load-carrying of vehicle, cause the longitudinal impact force in the vehicle ' to strengthen, thereby the impulsive force to the bathtub end plate also strengthens thereupon, causes the bathtub end plate easily to deform, and reduces its service life.
Summary of the invention
The objective of the invention is for overcome above-mentioned deficiency provide a kind of simple in structure, can alleviate draw beam weight, reduce, improve the bathtub railway bathtub open-top car underframe in service life bathtub end plate longitudinal impact force.
The bathtub that the present invention includes end carriage assembly, longitudinal beam, sleeper beam assembly, curb girder assembly, constitutes by base plate and end plate, the box draw beam that constitutes by upper cover plate, web and lower cover, it is characterized in that the upper cover plate tail end of described upper cover plate and the web tail end of web all are welded to connect with described end plate, wherein, described web tail end is the variable section structure that the cross section ecto-entad strengthens gradually.
The web tail end of the present invention's box draw beam is set to variable section structure, be connected under the condition of required rigidity and intensity between box draw beam and the bathtub guaranteeing, can reduce in the vehicle ' longitudinal impact force to the transmission of bathtub end plate, promptly reduce longitudinal impact force to the bathtub end plate, thereby improve the service life of bathtub, also can alleviate the weight of box draw beam simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a box draw beam structural representation.
Fig. 3 is the web structure scheme drawing.
Fig. 4 is the bathtub structural representation.
Fig. 5 is upper cover plate, web and end plate connection diagram.
Among the figure: 1-end carriage assembly, 2-longitudinal beam, 3-sleeper beam assembly, 4-curb girder assembly, 5-bathtub (5.1-base plate, 5.2-end plate), 6-box draw beam (6.1-upper cover plate, 6.1.1-upper cover plate tail end, 6.2-web, 6.2.1-web tail end, 6.3-lower cover).
The specific embodiment
Further specify the present invention below in conjunction with drawings and Examples.
Embodiment: end carriage assembly 1, longitudinal beam 2, sleeper beam assembly 3, curb girder assembly 4, the bathtub 5 that constitutes by base plate 5.1 and end plate 5.2, and the upper cover plate in the box draw beam 6 6.1 is all made in the usual way, the web tail end 6.2.1 of the web 6.2 in the box draw beam 6 is the variable section structure that the cross section ecto-entad strengthens gradually, the length of lower cover 6.3 is then consistent with the plane length of web 6.2 lower ends, and the upper cover plate tail end 6.1.1 of upper cover plate 6.1 and web tail end 6.2.1 all are welded to connect with end plate 5.2 promptly becomes the present invention.
Claims (1)
1. railway bathtub open-top car underframe, the bathtub (5) that comprises end carriage assembly (1), longitudinal beam (2), sleeper beam assembly (3), curb girder assembly (4), constitutes by base plate (5.1) and end plate (5.2), by the box draw beam (6) of upper cover plate (6.1), web (6.2) and lower cover (6.3) formation, it is characterized in that the upper cover plate tail end (6.1.1) of described upper cover plate (6.1) and the web tail end (6.2.1) of web (6.2) all are welded to connect with described end plate (5.2), wherein, the variable section structure that strengthens gradually for the cross section ecto-entad of described web tail end (6.2.1).
