Abstract
The utility model relates to an outer top plate of a railway vehicle body. The outer top plate integrally forms an arc-shaped appearance matching with the cross section of the vehicle body and a longitudinal length equal to the length of the vehicle body by adopting the structural style of assembling and welding a plurality of arc-shaped top plate components with convex ribs outside after being lapped. The outer top plate of the vehicle body is directly connected and installed on the outer side of a vehicle top frame without auxiliary added longitudinal mounting beams; the outer top plate is provided with an integral arc-shaped structure matching with the cross section of the vehicle body and the longitudinal length equal to the length of the vehicle body; and a plurality of the convex ribs are evenly arrayed longitudinally on the outer side of a main body of the outer top plate. As two lateral ends of the outer top plate are not provided with slightly curved rain eaves, a mould structure formed by integrally processing the outer top plate is comparatively simple and facilitates pressed forming control and has accurate processing size. The parallel convex ribs on the outer side can longitudinal provide bearing rigidity, saves the vehicle top longitudinal mounting beams, and not only reduce assembly processes of the outer top plate, but also effectively decrease the weight of a vehicle top portion and the costs of parts.
Description
Technical field
The utility model relates to a kind of roof sheet that constitutes the vehicle body of railway vehicle steel structure, belongs to mechanical manufacturing field.
Background technology
Along with the raising of guideway vehicle speed, require also further to improve for vehicle performance, can make it have good dynamic performance by changing contour of the vehicle and alleviating the car load deadweight.
The existing employed roof sheet of weathering steel car body adopt slab construction comparatively at large, and two side ends also is connected with the rain eaves of integral type arc.The roof sheet of this class formation, its material thickness is bigger, thereby needs to be equipped with baroque forming mould in manufacturing process.
In addition, the rain eaves and the roof sheet body difference of side end are bigger, thereby are difficult to once suppress out by mould, are not easy to the monolithic molding of roof sheet.In case roof sheet is suppressed out, just be difficult to adjust the local size and the profile in rain eaves zone, thereby the processed finished products rate is lower, wastes time and energy, the roof sheet tooling cost is higher.
Moreover the weight of above-mentioned existing roof sheet is big and longitudinal rigidity is relatively poor, and need assist when car body top assembly welding is processed increases longitudinal beam to improve the integral rigidity of roof.
The utility model content
Vehicle body of railway vehicle roof sheet described in the utility model, its design goal is to address the above problem and adopts the curved roof assembly of several piece tyre convex tendon to carry out assembly welding bonded assembly version again after overlapping, roof sheet forms the arcuate profile that is complementary with the car body section on the whole, and the longitudinal length isometric with car body.
For realizing above-mentioned design goal, described vehicle body of railway vehicle roof sheet, direct connection is installed in the outside of roof skeleton, and need not auxiliary vertical mounting rail that increases, and its keystone configuration is:
Roof sheet has the integral curved structure that is complementary with the car body section, and has the longitudinal length identical with car body.Body arranged outside at roof sheet has, several longitudinally evenly distributed parallel convex tendons.
As above-mentioned base case feature, because the roof sheet two side ends does not have little radian rain eaves, thereby the mould structure that roof sheet integral body shapes is comparatively simple, is convenient to the control accurate to dimension of compression moulding.
The parallel convex tendon in the outside can longitudinally provide load-bearing rigidity, can omit and the vertical mounting rail of the direct coupled roof of roof sheet, not only reduces the roof sheet assembling procedure, and reduces the weight and the component costs at car body top effectively.
Be to optimize roof sheet outside strength and stiffness, described convex tendon can be by extrusion process and form integral structure with the body of roof sheet.
Consider the dimensional restriction of existing processing mold, can be with row assembling again after the described car body roof sheet split processing.
Particularly, roof sheet carries out at least 1 middle top board of assembly welding bonded assembly and 2 side top boards after including mutual side direction overlap joint again.
Be further roof sheet processing and the assembling feasibility of improving, described middle top board and side top board are integral structure and continuous elongated member.
In sum, the utility model vehicle body of railway vehicle roof sheet has the following advantages:
Roof sheet forms the arcuate profile that is complementary with the car body section on the whole, and the longitudinal length isometric with car body,
Therefore finish size is comparatively accurate, have on the whole longitudinal rigidity good, be convenient to the stack-mounted characteristics.
2, as above-mentioned roof sheet structure, roof sheet can adopt thin material, thereby be convenient to when assembling, adjust at random roof sheet arc size with the roof skeleton, to reach the purpose of flexible control roof overall appearance planeness and aesthetic property, can pacify level of processing and appearance ratings that allotment of labor's preface improves the manufacturing vehicle body of railway vehicle from the scene.
3, as above-mentioned roof sheet structure, therefore two side ends rain eaves has reduced the structural complexity of roof sheet processing mold effectively at the logical more later on welding assembly of roof sheet compression moulding, and the presswork rate is higher, is easy to controlling dimension and appearance and modeling.
4, roof sheet has convex rib structure, has longitudinal rigidity preferably, can be directly and the assembling of roof skeleton, thus reduce component costs and the complete vehicle weight that uses vertical mounting rail to produce.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described further.
Fig. 1 is described car body roof sheet generalized section;
Fig. 2 is the overlap joint scheme drawing of described middle top board and side top board;
As depicted in figs. 1 and 2, middle top board 1, side top board 2, convex tendon 3.
The specific embodiment
Embodiment 1, as depicted in figs. 1 and 2, is applied to the car body roof sheet of guideway vehicle, is mounted on the outside of roof skeleton.Promptly after being assembled into body framing, roof sheet be have integral structure and elongated continuously, have the integrated support structure of identical longitudinal length with car body, and roof sheet has the integral curved structure that is complementary with the car body section.
Roof sheet includes mutual side direction overlap joint and carries out 2 middle top boards 1 of assembly welding bonded assembly and 2 side top boards 2 afterwards, again, the body of top board 1 and side top board 2 outside in each piece, be provided with several longitudinally evenly distributed parallel convex tendons 3, convex tendon 3 by extrusion process and with each piece in top board 1 and side top board 2 form integral structures.
Simultaneously, top board 1 and side top board 2 are integral structure and continuous elongated member in each piece, promptly have identical longitudinal length with car body.
