Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In a specific embodiment, the utility model provides a frame structure is arranged in railway container flatcar, and this frame adopts the form of independent component, has avoided the multiple connection between each roof beam body to have less dead weight. As shown in fig. 1, the frame structure comprises a center sill 3, and an end sill 1, a cross member 4 and a sleeper beam 2 which are respectively and independently mounted on the center sill 3, wherein the center sill 3 is a main supporting component, and the center sill 3 transversely penetrates through a chassis of the railway container flat car. End beam 1 fixed mounting in the both ends of well roof beam 3, end beam 1 is two, fixes the both ends at well roof beam 3 with modes such as welding or bolted connection respectively, and every end beam 1 all includes two cantilever beams, and two cantilever beams set up respectively in the both sides of well roof beam 3, that is to say, the cantilever beam that forms end beam 1 has four, and every two cantilever beams are an end beam 1 of a set of formation, the conformal two end beams 1 that form, and the both ends of well roof beam 3 are located to both ends roof beam 1 branch.

In actual work progress, in order to guarantee joint strength, avoid breaking and damaging in the transportation, end beam 1 preferably adopts welded mode to be fixed with well roof beam 3.

The cross beams 4 are arranged in the middle of the middle beam 3 along the length direction, in the specific implementation process, the number of the cross beams 4 can be two, and the two groups of cross beams 4 are arranged on two sides of the transverse central axis of the middle beam 3 relatively. The sleeper beam 2 is arranged on the middle beam 3, a frame side bearing 24 matched with the bogie side bearing 24 is fixedly connected to the sleeper beam 2, and one end, far away from the middle beam 3, of the sleeper beam 2 is flush with the outer end part of the frame side bearing 24. The width of the bolster 2 is shorter than the width of the end beam 1 and the cross beam 4, the width only reaches the position of the frame side bearing 24, the bolster only plays a role of matching with the bogie side bearing and only bears the side bearing load when the vehicle runs on a curve line, and therefore the external dimension and the plate thickness of the bolster 2 can be smaller. Thus, the body bolster 2 has only the function of mounting the frame side bearing 24 without its load-bearing capacity, and therefore, the width of the body bolster 2 can be made shorter, the body bolster 2 being shorter than the end beams 1 and the cross beams 4.

In addition, because the container corner fittings of vehicle transportation fall to the tip of end beam 1 and crossbeam 4 respectively, consequently end beam 1, crossbeam 4 are the cantilever beam, and its cross-sectional change follows the equal strong atress principle of cantilever beam, and the position of connecting portion diminishes to the tip from with well roof beam 3 gradually, and end beam 1 and crossbeam 4 have the same width, that is to say, the end beam is kept away from the terminal surface of well roof beam 3 is first holding surface, crossbeam 4 is kept away from well roof beam 3 terminal surface is the second holding surface, first holding surface with the second holding surface forms the holding surface of container corner fittings jointly, first holding surface with the plane that the second holding surface formed is on a parallel with the axis of well roof beam 3.

In actual production, the bolster 2 may be located between the cross beam 4 and the end beam 1 so as to correspond in position to the position of the bogie side bearing, improving structural rationality.

Specifically, as shown in fig. 2, the sleeper beam 2 includes a box-shaped beam body and a frame side bearing 24 installed on the box-shaped beam body, the frame side bearing 24 is detachably connected to the box-shaped beam body, the box-shaped beam body includes an upper cover plate 21, a lower cover plate 22, a web plate 23 and an end plate, and the box-shaped beam body is surrounded by the upper cover plate 21, the lower cover plate 22, the web plate 23 and the end plate. The detachable connection structure is adopted, so that the frame side bearing 24 and the sleeper beam 2 can be conveniently detached, the equipment maintenance and the part replacement are convenient, and the box type beam body is adopted, so that the lower dead weight can be conveniently realized on the premise of larger supporting force.

The frame side bearing 24 may be mounted to the lower cover 22 by bolts, or may be mounted to the lower cover 22 by other means such as snap-fit connection.

That is to say, the sleeper beam 2 comprises an upper cover plate 21, a lower cover plate 22, a web plate 23, a frame side bearing 24 and an end plate 25, wherein the upper cover plate 21, the lower cover plate 22 and the web plate 23 form a closed box-shaped cross section, and the frame side bearing 24 is fixedly connected to the lower cover plate 22 through bolts and matched with the bogie side bearing, so that the derailment prevention and overturn resistance safety of the vehicle in curve running are improved. At this time, the body bolster 2 only plays a role of bearing the side bearing load, and the body bolster 2 has a short shape and a width only up to the position of the frame side bearing 24, thereby further reducing the self weight.

In the above-mentioned embodiment, the utility model provides a frame construction is used for railway container flatcar, and this frame construction includes end beam 1, crossbeam 4 and sleeper beam 2 that are connected with well roof beam 3 respectively, wherein, well roof beam 3 transversely runs through the chassis of railway container flatcar, 1 fixed mounting of end beam in the both ends of well roof beam 3, crossbeam 4 along length direction install in the middle part of well roof beam 3, sleeper beam 2 install in well roof beam 3, just the rigid coupling has and is used for with bogie side bearing matched with frame side bearing 24 on the sleeper beam 2, sleeper beam 2 keeps away from the one end of well roof beam 3 with frame side bearing 24's outer tip parallel and level. In this way, the connection relation among the end beam 1, the sleeper beam 2 and the cross beam 4 is cancelled, so that the end beam 1, the sleeper beam 2 and the cross beam 4 respectively form independent components, and connecting components among the beams are not required to be arranged and the beams are not required to be extended to connecting positions; meanwhile, the width of the sleeper beam 2 only extends to the position of the frame side bearing 24, the length of the sleeper beam 2 is obviously shortened, and the dead weight of the frame is reduced by reducing the use of parts or the size specification of each beam, so that the technical problem of large dead weight of the frame in the prior art is solved.

In addition to above-mentioned frame structure, the utility model discloses still provide a railway container flatcar including this frame structure, other each partial structure of this railway container flatcar please refer to prior art, do not do here and describe repeatedly.
