The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Extremely shown in Figure 5 as Fig. 1, the embodiment of the invention, a kind of pantograph flow guiding device of high-speed track vehicle comprises two streamlined reefer housings 1 that are fixed on the roof (not shown), and streamlined reefer housing 1 vertically is oppositely arranged along roof in the both sides of roof pantograph (not shown).
When the vehicle high-speed cruising, the noise that pantograph produced mainly is the friction that comes between pantograph and the air, stop the friction between air and the pantograph, will reduce noise, the setting of streamlined reefer housing 1 just can stop crosswind directly to blow to pantograph, thereby reduce the influence of crosswind, reduced the sound pollution source of pantograph pantograph.
The height of streamlined reefer housing 1 is high more, the effect of its sound insulation is good more, also can corresponding increase running resistance but streamlined reefer housing 1 is too high, so the height of streamlined reefer housing 1 can not be too high can not be low excessively, cross the effect of low out of reach sound insulation, according to the structure measuring and calculating of most of pantographs, the height of the distance from top roof of general streamlined reefer housing 1 just can satisfy above-mentioned requirements between 450mm to 850mm.
It is up-narrow and down-wide trapezoidal that the vertical section of streamlined reefer housing 1 roughly is, make its two windward side in the vertical and airflow direction when the vehicle high-speed cruising form certain included angle, windstream just can upwards flow along obliquely windward side like this, just can reduce the windage of streamlined reefer housing 1 when vehicle operating relatively, the noise that is produced in the time of also can reducing simultaneously streamlined reefer housing 1 itself with windage.The angle at two trapezoidal base angles is generally between 20 ° to 45 °, and this angle is more little, and windage will be more little, but because the length of roof is certain, if the angle too small at two trapezoidal base angles, it is low that the height of streamlined reefer housing 1 is spent, and can not satisfy the requirement of sound insulation.
For alleviating the single-piece weight of streamlined reefer housing 1, streamlined reefer housing 1 is vertically very long, arrange along whole roof, its horizontal width just can not be too big so, but when the vehicle high-speed cruising, streamlined reefer housing 1 stressed very big is so need to strengthen the width of bottom, satisfy its mechanics requirement, it is fixing that it is stabilized in more.For addressing this problem, having established a chamfering 3, be used to widen the width of streamlined reefer housing 1 bottom with the middle and lower part of the side of the corresponding streamlined reefer housing 1 of pantograph, the radius of chamfering 3 can be between the R15mm to R40mm.Equally, chamfering 3 is set, also can plays and reduce the windage effect, thereby further reduce the influence of windstream pantograph at this place.
Same in order to alleviate the weight of streamlined reefer housing 1, streamlined reefer housing 1 is designed to the casing shape structure of hollow, but the strength and stiffness that can cause streamlined reefer housing 1 like this do not satisfy the requirement of vehicle high-speed cruising, in order to strengthen its strength and stiffness, inner transverse at streamlined reefer housing 1 is provided with a plurality of first reinforcement gussets 4, first strengthen gusset 4 streamlined reefer housing 1 in by the end to the setting of pushing up, first shape and the streamlined reefer housing 1 in-to-in shape of strengthening gusset 4 is complementary, and be fixed on the inwall of streamlined reefer housing 1, but in order to alleviate the weight of streamlined reefer housing 1, cost-cutting, streamlined reefer housing 1 and first is strengthened gusset 4 and is all made by glass-reinforced plastic material, because the requirement of glass-felt plastic manufacture craft, also because in order to reduce windage, 1 top of streamlined reefer housing makes arc line type, so as shown in Figure 4, first top of strengthening gusset 4 does not arrive the top of streamlined reefer housing 1, and this does not influence the strength and stiffness of streamlined reefer housing 1, because the main force part of streamlined reefer housing 1 is in its bottom.
For the requirement of the strength and stiffness that satisfy streamlined reefer housing 1, can not increase the weight of streamlined reefer housing 1 again, so that first quantity of strengthening gusset 4 is difficult for is too much or very few, generally strengthen gusset 4 with the pitch arrangement first of 200mm to 500mm.
Because the bottom of streamlined reefer housing 1 is stressed bigger,, strengthens gusset 4 in each first bottom of strengthening gusset 4 near first one second reinforcement gusset 5 is set again in order to increase the strength and stiffness of its bottom.
As shown in Figure 4, strengthen on the side of gusset 4 one deck expanded material 7 being arranged first, it mainly is for when glass-felt plastic is made, and satisfies the requirement of the typing of glass-felt plastic.
This device also comprises a mount pad 6, the bottom of streamlined reefer housing 1 is provided with a plurality of detachable caps 8 that are used for hold-down bolt, open detachable cap 8, pass with bolt streamlined reefer housing 1 is fixed on the mount pad 6, close detachable cap 8 then, 6 of mount pads directly are welded on the roof, can make like this streamlined reefer housing 1 more firm stable be fixed on the roof.
Under the requirement of the strength and stiffness that satisfy streamlined reefer housing 1, in order further to alleviate the weight of streamlined reefer housing 1, can open some openings 9 in the side bottom of a side of streamlined reefer housing 1 relative pantograph, will stagger and first strengthen gusset 4 and second and strengthen gusset 5 in the position of these openings 9.
As mentioned above, given in conjunction with the accompanying drawings and embodiments scheme content can derive the similar techniques scheme.In every case be the content that does not break away from technical solution of the present invention, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solution of the present invention according to technical spirit of the present invention.
