Abstract
The invention relates to a special car body of a container for railways. The special car body comprises a middle beam, and two side beams which are arranged at both sides of the middle beam and have the same length as the middle beam, wherein the side beams are in semi-bracket structures which are formed by thin plates in a splicing way, the lower end surfaces of the side beams and the lower end surface of the middle beam are positioned in the same horizontal plane, and the upper end surfaces of the side beams are higher than that of the middle beam; and the special car body also comprises end beams which are tightly and fixedly connected to both ends of the middle beam and the side beams, two bolster beams which are tightly and fixedly connected between the two side beams of the inner sides of the end beams and are parallel to the end beams, and a plurality of transverse beams which are tightly and fixedly connected between the two side beams of the inner sides of the bolster beams and are parallel to the bolster beams, and the upper end surfaces and the lower end surfaces of the end beams, the bolster beams and the transverse beams are respectively parallel and level to the upper end surface and the lower end surface of the middle beam. The special car body disclosed by the invention has the advantages of little vertical accelerated speed, long fatigue life of the car body, weak vertical jolt of the car body, little adverse effect of the vertical interference to the self of the car body, the container and the loaded goods during the transportation, high whole strength and stiffness of the car body and the like.
Description
Technical field
The present invention relates to a kind of rail car body, particularly about a kind of railway container car body.
Background technology
As shown in Figure 1 to 4, at present, the tabular car body that the existing railway of China generally adopts transverse beam 2 assembly weldings that include the longitudinal beam 1 of a central sill 10, two curb girders 11 and include two sleeper beams 20, two end carriages 21, some crossbeams 22 to form with container car body, two sleeper beam 20 centers are all fastenedly connected a cartridge 23, on the sleeper beam 20 of cartridge 23 both sides, be all fastenedly connected a symmetrical side bearing 24, on car body, be also preinstalled with some tapered end (not shown)s, when transport, by the tapered end locking on the lock on freight container and car body.Existing railway is positioned at same level with the longitudinal beam 1 of container car body with the upper surface of transverse beam 2, the structure high in the middle of the general all employings of central sill 10 and curb girder 11, two ends are low, to improve its load-carrying capacity, but this version exists car body, deadweight concentrates within the scope of car body center and certain altitude relatively.Train is in operational process, and the live load between wheel and track is delivered to bogie truck, and bogie truck is delivered to the goods of car body and delivery by cartridge 23 and side bearing 24.When track to one of car body vertically to excitation time, will cause vertical acceleration bigger than normal, cause the dynamic stress of car body to strengthen, thereby reduce the fatigue life of car body, and what can make car body vertically jolts more severely, and the goods that also can deliver freight container and freight container when serious produces adverse influence.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of intensity, rigidity greatly and the less railway of vertical acceleration container car body.
For achieving the above object, the present invention takes following technical scheme: a kind of railway container car body, it is characterized in that, it comprises a central sill, two are arranged on described central sill both sides and the curb girder isometric with it, the half bracket shape structure that described curb girder adopts thin plate splicing to form, the lower surface of described curb girder lower surface and central sill is positioned in same level, and the upper surface of described curb girder is higher than the upper surface of central sill; It also comprises that one is fastenedly connected the end carriage at described central sill and curb girder two ends, two are fastenedly connected between two curb girders of described end carriage inner side and the sleeper beam parallel with described end carriage, and being somely fastenedly connected between two curb girders of described sleeper beam inner side and the crossbeam parallel with sleeper beam, upper surface, the lower surface of described end carriage, sleeper beam and crossbeam are all concordant with upper surface, the lower surface of central sill.
Described in each, the inner side of curb girder is all equidistantly fastenedly connected some for increasing the wedge-like floor of its intensity.
The box-structure that described central sill adopts other shaped steel assembly welding of Yi shape steel or similar cross-section height to form.
Described curb girder height is determined according to the requirement of load-carrying and railway clearance design.
The present invention is owing to taking above technical scheme, it has the following advantages: the present invention is owing to having reduced middle depth of beam, increase both sides depth of beam, make the upper surface of central sill and curb girder be positioned at different horizontal surfaces, therefore, disperseed car body deadweight, thereby effectively reduce vertical acceleration, improve car body fatigue life, weakened the vertical of car body and jolted, finally reduced vertical interference in transportation to car body self, freight container and the adverse effect that carries cargo.In addition the strength and stiffness of car body entirety, have also been improved.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 5, Figure 6, the present invention includes a central sill 3, the both sides of central sill 3 all arrange an in parallel and isometric curb girder 4, the half bracket shape structure that curb girder 4 adopts thin plate splicing to form, the lower surface of the lower surface of curb girder 4 and central sill 3 is positioned in same level, and the upper surface of curb girder 4 is higher than the upper surface of central sill 3.The two ends of central sill 3 and two curb girders 4 are all fastenedly connected an end carriage 5, between two curb girders 4 of two end carriage 5 inner sides, all interval is fastenedly connected between the central sill 3 of sleeper beam 6, two sleeper beam 6 inner sides parallel with end carriage 5 and two curb girders 4 and is all equidistantly fastenedly connected some crossbeams 7 parallel with sleeper beam 6.Upper surface, the lower surface of end carriage 5, sleeper beam 6 and crossbeam 7 are all concordant with upper surface, the lower surface of central sill 3.The inner side of each curb girder 4 is all equidistantly fastenedly connected some for increasing the wedge-like floor 8 of curb girder semi-finals degree.
In the above-described embodiments, central sill 3 adopts the box-structure that other shaped steel assembly welding of Yi shape steel or similar cross-section height forms.
