The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 3 and Fig. 4 are front view and the lateral plan of staircase for the rolling stock of the utility model one embodiment.As shown in Figure 3, Figure 4, the rolling stock of the utility model one embodiment comprises the connecting panel 1 being oppositely arranged and is arranged on the handrail 2 between described connecting panel 1 with staircase, described connecting panel 1 is arranged between side cross band 4 adjacent on side wall, particularly, the two ends of described connecting panel 1 are welded on respectively on side cross band 4 adjacent on side wall.The length of the connecting panel 1 of the present embodiment can be the distance between sides adjacent cross band 4, and its length is relatively short, not only can expendable weight, but also can save cost.
In a kind of embodiment, on described connecting panel 1, be also provided with fulcrum block 3 therein, particularly, described fulcrum block 3 can be welded on described connecting panel 1, and described fulcrum block 3 is also welded on the side plate 5 of side wall simultaneously.In the present embodiment, at the fulcrum block 3 of the middle part of each connecting panel 1 inner side welding rectangle, the relative connecting panel 1 of fulcrum block 3 protrudes towards side plate 5 directions, and the outside face of projection is welded on side plate 5 simultaneously.By setting support seat 3, connecting panel 1 is welded on side cross band 4 and side plate 5 simultaneously, has not only strengthened the connection reliability of staircase, also strengthened the strength and stiffness of side wall.
Fig. 5 is the lateral plan of staircase for the rolling stock of another embodiment of the utility model, as shown in Figure 5, the rolling stock of the present embodiment comprises the connecting panel 1 being oppositely arranged and is arranged on the handrail 2 between described connecting panel 1 with staircase, the two ends of wherein said connecting panel 1 are welded on respectively on side cross band 4 adjacent on side wall, the inner side (towards a side of side plate) of described connecting panel 1 is directly welded on the side plate 5 of side wall simultaneously, this rolling stock is high with staircase anti-fatigue life, is conducive in addition guarantee the strength and stiffness of side wall.
As shown in Figure 6, the rolling stock of above-mentioned arbitrary embodiment has salient with the handrail 2 of staircase, and for example it can be a few font round steel, and the middle part of a few font round steel forms described salient 21, and the two ends of salient 21 form connecting portion 22.On the connecting panel 1 being oppositely arranged described in the two ends (being connecting portion 22) of handrail 2 are welded on respectively, and the salient 21 of the described handrail 2 dorsad side plate 5 of side wall arranges, be conducive to form larger space, thus the upper and lower vehicle of convenient operation personnel or carry out other operation.The width of the salient 21 of the handrail 2 of the present embodiment is less than the width of connecting panel 1, thereby in convenient operation personnel operation, can also under the prerequisite that meets rolling stock gauge, suitably increase the width of car body.In other embodiments, handrail 2 can also be flange, and its two ends can directly be welded on the connecting panel 1 being oppositely arranged, and now flange entirety forms described salient 21.
Rolling stock of the present utility model comprises the rolling stock staircase of above-mentioned arbitrary embodiment, its staircase is set directly at connecting panel 1 between adjacent side cross band 4, thereby can under the prerequisite that meets rolling stock gauge, suitably increase width over sides of car body, for example increasable maximum width is the width of a connecting panel, thereby is conducive to increase load-carrying and the freight volume of car body.
Finally it should be noted that: above each embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or some or all of technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of the each embodiment technical scheme of the utility model.
