Description
Technical field
The present invention relates to a kind of rolling stock, particularly about a kind of lower floor's underframe of double-layered transport vehicles rolling stock.
Background technology
At present, lower floor's underframe of domestic existing double-decker transport railway vehicle has two kinds: a kind of is by the quadra structure running through longitudinal central sill, curb girder and sleeper beam, end carriage, some cross bearers, some needle beams and longitudinal beam and form, and plane lays perforated floors to each beam; Another is ship type framed structure recessed between two sleeper beams that are made up of two draw beams, two groups of little side walls, two groups of sleeper beams, two groups of end carriages, some needle beams and longitudinal beams, and plane lays perforated floors to each beam.
But above-mentioned Liang Zhong lower floor Undercarriage structure also exists following problem: 1) under the constraint of existing vehicle gauge of the locomotive, and lower floor's loading height can not meet the trend that roadlice oad increases day by day; 2) tool box is on lower floor's bottom frame floor of railway vehicle, between both walls, occupies the inner space of railway vehicle.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of lower floor's underframe of double-layered transport vehicles railway vehicle, this underframe can increase operational space during lower floor's efficient loading height and the railway vehicle entrucking of double-layered transporting railway vehicle.
For achieving the above object, the present invention is by the following technical solutions: a kind of lower floor's underframe of double-layered transport vehicles rolling stock, comprises by the quadra structure running through longitudinal central sill, the longitudinal curb girder being positioned at described central sill both sides and the horizontal end carriage that is positioned at described central sill two ends and form, in described quadra structure, described in described central sill and two, between longitudinal curb girder, a longitudinal beam is set respectively, some needle beams are arranged at intervals with between end carriage horizontal described in two, being respectively arranged with a horizontal sleeper beam near horizontal end carriage position described in two, between sleeper beam horizontal described in two, be arranged at intervals with some cross bearers, plane all lays perforated floors to longitudinal curb girder described in plane and two to described central sill, described longitudinal curb girder, longitudinal beam, the upper plane of needle beam is positioned at same plane, and lower than the upper plane of described central sill, described horizontal sleeper beam simultaneously, cross bearer is notch cuttype beam, the two is positioned at same plane with the upper cover plate of described central sill coupling end and the upper plane of described central sill, same plane is positioned at the upper cover plate of described longitudinal curb girder coupling end and the upper plane of described longitudinal curb girder, middle high to make described quadra structure be formed in the vertical, " convex " character form structure that both sides are low.
Tool box is provided with between two described cross bearers that described perforated floors bottom is adjacent.
Described tool box is welded by described longitudinal curb girder, two cross bearer webs, tool box web, instrument case lid and tool box base plates.
Described longitudinal curb girder is trough girder.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention is by the longitudinal curb girder in quadra structure, longitudinal beam, the upper plane of needle beam is arranged at same plane, and lower than the upper plane of central sill, simultaneously by horizontal sleeper beam, cross bearer is set to notch cuttype beam, the two is positioned at same plane with the upper cover plate of central sill coupling end and the upper plane of central sill, same plane is positioned at the upper cover plate of longitudinal curb girder coupling end and the upper plane of longitudinal curb girder, such quadra structure is formed middle high in the vertical, " convex " character form structure that both sides are low, thus add lower floor's efficient loading height of double-layered transporting railway vehicle, expand suitable fortune scope.2, tool box is arranged between adjacent two cross bearers of perforated floors bottom by the present invention, thus operational space when adding railway vehicle entrucking, scratch arrangements for automotive doors when avoiding driver to get on or off the bus, improves the safety of loading and reinforcing automobile.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the present invention includes by the quadra structure 1 running through longitudinal central sill 11, the longitudinal curb girder 12 being positioned at central sill 11 both sides and the horizontal end carriage 13 that is positioned at central sill 11 two ends and form.In quadra structure 1, between central sill 11 and two longitudinal curb girders 12, a longitudinal beam 14 is set respectively, some needle beams 15 are arranged at intervals with between two horizontal end carriages 13, being respectively arranged with a horizontal sleeper beam 16 near two horizontal end carriage 13 positions, between two horizontal sleeper beams 16, be arranged at intervals with some cross bearers 17.Plane all lays perforated floors 2 to central sill 11 for plane and two longitudinal curb girders 12, between two cross bearers 17 that perforated floors 2 bottom is adjacent, is provided with tool box 3.
As shown in Figure 2 and Figure 3, the upper plane of longitudinal curb girder 12, longitudinal beam 14, needle beam 15 is positioned at same plane, and lower than the upper plane of central sill 11, horizontal sleeper beam 16, cross bearer 17 are set to notch cuttype beam simultaneously, the two is positioned at same plane with the upper cover plate of central sill 11 coupling end and the upper plane of central sill 11, same plane is positioned at, high in the middle of such quadra structure 1 is formed in the vertical, both sides are low " convex " character form structure with longitudinal upper cover plate of curb girder 12 coupling end and the upper plane of longitudinal curb girder 12.
As shown in Figure 4, Figure 5, tool box 3 is welded by longitudinal curb girder 12, adjacent two cross bearer 17 webs, tool box web 32, instrument case lid 33 and tool box base plates 34.
In above-described embodiment, longitudinal curb girder 12 is trough girder.
The various embodiments described above are only for illustration of the present invention; wherein the structure of each parts, connection mode and manufacture craft etc. all can change to some extent; every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
