The lower-layer underframe comprises a frame structure composed of a middle beam, longitudinal side beams and transverse end beams, wherein the longitudinal side beams are located on two sides of the middle beam, and the transverse end beams are located at the two ends of the middle beam; a longitudinal beam is arranged between the middle beam and each side beam, a plurality of small transverse beams are arranged between the two end beams, the positions close to the two end beams are respectively provided with a transverse sleeper beam, and a plurality of large transverse beams are arranged between the two sleeper beams; floor boards with holes are laid on the upper plane of the middle beam and the upper planes of the two side beams, and the upper planes of the side beams, the upper planes of the longitudinal beams and the upper planes of the small transverse beams are located on the same plane and lower than the upper plane of the middle beam; the sleeper beams and the large transverse beams are stepped beams, upper covering plates of the connection ends of the sleeper beams and the large transverse beams and the middle beam and the upper plane of the middle beam are located on the same plane, upper covering plates of the connection ends of the sleeper beams and the large transverse beams and the side beams and the upper planes of the side beams are located on the same plane, and therefore the square frame structure forms an inverted-T-shaped structure in the longitudinal direction. The lower-layer underframe is capable of increasing the effective loading height of the lower layer of the double-layer automobile transportation railway vehicle and operation space when the double-layer automobile transportation railway vehicle is loaded, and suitable for various double-layer automobile transportation railway vehicles.
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 transportation railway vehicle has two kinds: a kind of is by running through the quadra structure that central sill, curb girder and sleeper beam, end carriage, some cross bearers, some needle beams and longitudinal beam form longitudinally, laying perforated floors on each beam in plane; Another is recessed ship type framed structure between two sleeper beams that consist 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, on each beam, in plane, lays perforated floors.
But above-mentioned Liang Zhong lower floor Undercarriage structure exists following problem: 1) under the constraint of existing vehicle gauge of the locomotive, lower floor's loading height can not meet the trend that roadlice oad increases day by day; 2) tool box, on lower floor's bottom frame floor of railway vehicle, between both walls, has taken 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, operational space when this underframe can increase the lower floor efficient loading height of double-layered transporting railway vehicle and railway vehicle entrucking.
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 running through central sill longitudinally, is positioned at longitudinal curb girder of described central sill both sides and is positioned at the quadra structure that the horizontal end carriage at described central sill two ends forms, in described quadra structure, described in described central sill and two, longitudinally between curb girder, a longitudinal beam is set respectively, described in two, laterally between end carriage, be arranged at intervals with some needle beams, being respectively arranged with a horizontal sleeper beam near horizontal end carriage position described in two, described in two, laterally between sleeper beam, be arranged at intervals with some cross bearers, on described central sill, described in plane and two, on longitudinal curb girder, in plane, all lay perforated floors, described longitudinal curb girder, longitudinal beam, the upper plane of needle beam is positioned at same plane, and the upper plane lower than described central sill, described horizontal sleeper beam of while, cross bearer is notch cuttype beam, the two and the upper cover plate of described central sill coupling end and the upper plane of described central sill are positioned at same plane, be positioned at same plane with the upper cover plate of described longitudinal curb girder coupling end and the upper plane of described longitudinal curb girder, so that described quadra structure is high in the middle of forming in the vertical, " protruding " character form structure that both sides are low.
Between adjacent two the described cross bearers in described perforated floors bottom, be provided with tool box.
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 layout of needle beam is in same plane, and the upper plane lower than central sill, simultaneously by horizontal sleeper beam, cross bearer is set to notch cuttype beam, the two and the upper cover plate of central sill coupling end and the upper plane of central sill are positioned at same plane, be positioned at same plane with the upper cover plate of longitudinal curb girder coupling end with the upper plane of longitudinal curb girder, quadra structure is high in the middle of forming in the vertical like this, " protruding " character form structure that both sides are low, thereby increased lower floor's efficient loading height of double-layered transporting railway vehicle, expanded suitable fortune scope.2, the present invention is arranged on tool box between adjacent two cross bearers of perforated floors bottom, thus the operational space while having increased railway vehicle entrucking, the arrangements for automotive doors that scratches while avoiding driver to get on or off the bus, the safety that has improved loading and reinforcing automobile.
