Abstract

The utility model provides a railway vehicle body. The railway vehicle body comprises an underframe, side walls respectively fixedly arranged on two sides of the underframe along the longitudinal direction, end walls respectively arranged at the front end and at the rear end of the underframe along the transverse direction, and a top plate covering the two side walls and the two end walls. A guest room is defined by the underframe in an enclosing mode, the side walls, the end walls and the top plate. The cross section of the top plate is of an arc shape protruding towards the guest room. Chutes for allowing liquid to flow through and extending along the longitudinal direction are respectively formed in joints of two sides of the top plate and the side walls at two sides of the top plate, and two drainage channels for respective drainage and discharging of the liquid in the chutes are fixedly arranged on outer sides of the end walls. According to the railway vehicle body, damage to an air conditioning unit and electrical elements in electrical equipment on the vehicle top and corrosion of the vehicle body caused by the fact that rainwater and air conditioner condensate water are gathered on the top plate can be avoided; and maintenance of the drainage channels is convenient, and even water seepage of the drainage channels occurs, water cannot flow into the guest room.

The specific embodiment

" vertically " described in the utility model is meant the car body bearing of trend, a plurality of car bodies are longitudinally arranged and are constituted guideway vehicle, " preceding " refers to the guideway vehicle service direction, " back " refer in the vertical and with preceding opposite direction, " laterally " then refers in horizontal surface perpendicular to direction longitudinally.

Fig. 3 is the front view of the utility model embodiment; Fig. 4 be among Fig. 3 B-B to cutaway view; Fig. 5 is the enlarged drawing at I place among Fig. 3; Please refer to Fig. 3, Fig. 4 and Fig. 5, present embodiment provides a kind of vehicle body of railway vehicle, comprise: underframe 13, respectively longitudinally be fixedly installed on the side wall 11 of underframe 13 both sides, respectively along being horizontally installed on the headwall 22 at underframe 13 forward and backward two ends, and covering top board 21 on two side walls 11 and the headwall 22, underframe 13, side wall 11, headwall 22 and top board 21 surround the guest room; The cross-sectional plane of top board 21 is the arc that protrudes outside described guest room; Form the chute 3 that flows through for liquid, extend longitudinally respectively in top board 21 both sides and both sides side wall 11 junctions, and be set with two in headwall 22 outsides and be used for the drainage channel 4 of respectively the liquid drainage of chute 3 being discharged.

Particularly, car body can be rectangular-shaped substantially, two side walls 11 lay respectively at the place, side that cuboid two extends along its length, the side that 22 of headwalls lay respectively at the extension of cuboid two Widths goes out, underframe 13 can be positioned at place, cuboid bottom surface, and 21 on top board can be positioned at the end face place of cuboid; Wherein, top board 21 should be an arc that extends longitudinally, and the cross-sectional plane of this arc is to the outside, the guest room projection that car body surrounds, and promptly is the arch of protruding upward, so that the liquid such as condensed water of rainwater, air-conditioning unit are flowed by the longitudinal center alignment both sides of top board.

Chute 3 can utilize the connection structure between side wall 11 and the top board 21 to form, for example, side wall 11 adopts the big section compound type of aluminum alloy hollow extrudate, this extrudate comprises internal layer aluminium sheet and outer aluminium sheet, the top of the outer aluminium sheet of side wall 11 can be arranged to exceed top board 21 edges, so that the end face of the part that should the skin aluminium sheet exceeds top board 21 and top board 21 surrounds this chute 3 jointly; Perhaps, chute 3 can be the U-shaped open slot that extends longitudinally, and can be fixed into one or one-body molded with top board 21 with top board 21.Wherein, the two ends of chute 3 can extend to the headwall 22 at forward and backward two ends respectively, with the liquid drainages such as condensed water of rainwater, air-conditioning unit to two ends headwall 22 positions.

Drainage channel 4 can be the aluminum pipe that extends up and down, and two aluminum pipes on the same headwall 22 can lay respectively at this headwall 22 both sides, and the top ports of each aluminum pipe is connected with cooresponding chute 3, and the bottom nozzle of aluminum pipe 4 can extend to underframe 13 belows.

Preferably, can on top board 21 and at top board 21 longitudinal centerline places, be installed with the air-conditioning unit; Like this, the condensed water that produces in the air-conditioning unit working process is after falling under gravity on the top board 21, because the middle part projection of top board 21, this condensed water then flow in the chute 3 of top board 21 both sides, flow to headwall 22 places that are positioned at car body front end and/or rear end along chute then, flowing out via the drainage channel on the headwall 22 4.Further, even when rainy, but the arcuate in shape of top board 21 also the time rainwater can not accumulate in top board 21 longitudinal centerline near zones, but the chute 3 and the drainage channel on chute 3 and headwall 22 that still flow to top board 21 both sides are discharged outside the car body.

This shows, guideway vehicle air conditioner condensate water that present embodiment provides and rain-water drainage structure, the liquid such as condensed water that rainwater, the work of air-conditioning unit are produced flow to forward and backward two headwalls 22 via the chute 3 of top board 21 both sides rapidly, be expelled to outside the car body via the drainage channel on the headwall 22 4 again, avoided in the prior art rainwater to accumulate on the top board and cause the damage of electric elements in air-conditioning unit and the roof electrical equipment and the corrosion of car body; In addition, drainage channel is arranged on the headwall outside, make drainage channel maintenance and safeguard convenient, even and if drainage channel seep water, can not flow into inside, guest room yet, also avoided the normal carrying of guideway vehicle to move.

In the above-described embodiments, shown in Fig. 3, Fig. 6 A and Fig. 6 B, two aluminum pipes 4 can lay respectively at headwall 22 both sides and side wall 11 junctions, and aluminum pipe 4 can extend along the both sides of the edge line of headwall 22.

Further, the cross-sectional plane of aluminum pipe 4 can be rectangular, and a side of aluminum pipe 4 can be fixed on the outside face of headwall 22 by welding manner, and is simple in structure, saved the complicated pipelines connection.Make things convenient for assembly process, and can not take too much space, helped the assembly manipulation of other parts.

It should be noted that at last: above each embodiment only in order to the explanation the technical solution of the utility model, 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: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
