The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model embodiment, a kind of guiding device of EMU pantograph comprises two streamlined reefer housings 2 that are fixed on the roof 1, streamlined reefer housing 2 vertically is oppositely arranged along roof 1 in the both sides of roof 1 pantograph (not shown).
When the motor train unit 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 2 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 2 is high more, the effect of its sound insulation is good more, also can corresponding increase running resistance but streamlined reefer housing 2 is too high, so the height of streamlined reefer housing 2 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 2 just can satisfy above-mentioned requirements between 300mm to 850mm.
As shown in Figure 1, it is up-narrow and down-wide trapezoidal that the vertical section of streamlined reefer housing 2 roughly is, make its two windward sides 3 in the vertical and airflow direction when the motor train unit 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 2 when vehicle operating relatively, the noise that is produced in the time of also can reducing simultaneously streamlined reefer housing 2 itself with windage.The angle at two trapezoidal base angles 4 is generally between 20 ° to 45 °, this angle is more little, 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 2 is spent, and can not satisfy the requirement of sound insulation, so the angle at preferred base angle 4 is 30 °.
In order further to reduce the air resistance of streamlined reefer housing 2 when moving, the windward side 3 of streamlined reefer housing 2 rear and front ends is designed to ellipsoid surface, just the cross section of the vertical direction of windward side 3 and the cross section on the horizontal direction are camber line, and the radian of camber line in vertical direction is less, and is more level and smooth.
In order to alleviate the weight of streamlined reefer housing 2, streamlined reefer housing 2 is designed to the casing shape structure of hollow, but the strength and stiffness that can cause streamlined reefer housing 2 like this do not satisfy the requirement of vehicle high-speed cruising, in order to strengthen its strength and stiffness, as shown in Figure 1, inner transverse at streamlined reefer housing 2 is provided with a plurality of reinforcement gussets 7, strengthen gusset 7 streamlined reefer housing 2 in by the end to the setting of pushing up, shape and the streamlined reefer housing 2 in-to-in shapes of strengthening gusset 7 are complementary, and be fixed on the inwall of streamlined reefer housing 2, but in order to reduce windage, as shown in Figure 3,2 top of streamlined reefer housing makes arc line type, so as shown in Figure 1, the top of strengthening gusset 7 does not arrive the top of streamlined reefer housing 2, and this does not influence the strength and stiffness of streamlined reefer housing 2, because the main force part of streamlined reefer housing 2 is in its bottom.As shown in Figure 4, strengthen gusset 7 and be designed to " worker " font, strengthen gusset 7 and adopt composite material to make, both sides are frp layer, and the centre is the three dimension stereo fabric layer.
For the requirement of the strength and stiffness that satisfy streamlined reefer housing 2, can not increase the weight of streamlined reefer housing 2 again, be difficult for too much or very few so strengthen the quantity of gusset 7, generally strengthen gusset 7 with the pitch arrangement of 400mm to 700mm.
Because the bottom of streamlined reefer housing 2 is stressed bigger,, also can near strengthening gusset 7 a reinforced rib (not shown) be set again in each bottom of strengthening gusset 7 in order to increase the strength and stiffness of its bottom.
As shown in Figure 5, in order to reduce the weight of streamlined reefer housing 2, streamlined reefer housing 2 adopts composite material to make, and its internal layer is a three dimension stereo fabric interlayer 5, and its skin is a frp layer 6, and the thickness of three dimension stereo fabric interlayer 5 is 8mm, and the thickness of frp layer 6 is 0.5mm-1mm.
As shown in Figure 3, the inside bottom of streamlined reefer housing 2 installation portion 10 that stretches out, because the requirement of roof 1 structure, installation portion 10 is the level of state, the exterior bottom of streamlined reefer housing 2 installation portion 11 that also stretches out, installation portion 11 is provided with a plurality of rectangle mounting grooves 12 in vertical state on installation portion 10, a plurality of rectangle mounting grooves 13 are set on installation portion 11.
This device comprises two mount pads 8 and 9, and mount pad 8 and 9 is separately fixed on the roof 1, and the installation portion 10 of streamlined reefer housing 2 inside bottom is captiveed joint with mount pad 8 by bolt 14, and the installation portion 11 of streamlined reefer housing 2 exterior bottom is captiveed joint with mount pad 9 by bolt 14,
The setting because installation portion 10 and 11 all stretches out, so the bolt 14 that captive joint is used all is to install from the outside, this will greatly improve the work efficiency of streamlined reefer housing 2 installations and the comfort feature of maintenance.
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 solutions of the utility model, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model.
