Abstract
The utility model discloses a railway tub gondola car chassis and relates to a chassis on a railway tub gondola car, which mainly overcomes the defects that the existing chassis can not meet the use requirement of a large axle load railway tub gondola car, and a tub end plate is deformed easily and has a short service life. The railway tub gondola car chassis comprises an end beam assembly, a longitudinal beam, a pillow beam assembly, a side beam assembly, a tub consisting of a base plate and an end plate, and a box-type traction beam consisting of an upper cover plate, a web and a lower cover plate. The utility model is characterized in that the tail end of the upper cover plate and the tail end of the web are both welded with the end plate, wherein the tail end of the web is in a variable cross-section structure gradually enlarged from outside to inside. The utility model has the advantages that the structure is simple, the weight of the traction beam can be reduced, the longitudinal impact force to the tub end plate is reduced, and the service life of the tub is prolonged.
Description
Technical field
The utility model relates to railway bathtub open-top car, relates 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 purpose of this utility model be 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 utility model 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, 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 utility model 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 the utility model structural representation.
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 utility model 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 utility model.
