Extremely shown in Figure 6 such as Fig. 1, roof 1, windage brake equipment 2, streamlined reefer housing 3, cover body 4, inner ring 5 is strengthened gusset 6, glass-felt plastic 7, three dimension stereo fabric 8, mounting groove 9, mounting hole 10.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1, roof 1 at train is installed with a windage brake equipment 2, when high-speed train braking, the top cover of windage brake equipment 2 upwardly opens certain angle, top cover produces running resistance, thereby the auxiliary brake action that produces to remedy the defective of adhesion braking under the high speed damped condition, is guaranteed the safe and reliable braking of high speed train.One streamlined reefer housing 3 is set around windage brake equipment 2, it is the centre that windage brake equipment 2 is arranged on streamlined reefer housing 3, when vehicle high-speed moves, streamlined reefer housing 3 can reduce air-flow to the impact of windage brake equipment 2, reduce the sound pollution source of windage brake equipment 2, thereby effectively reduced the noise of windage brake equipment 2.
Such as Fig. 2, Fig. 3 and shown in Figure 4, streamlined reefer housing 3 comprises a cover body 4, and cover body 4 arranges around windage brake equipment 2, and the periphery of cover body 4 is the stream line pattern curve form, and matches with the top cover curved surface of windage brake equipment 2, and one integrated mass can not increase resistance yet.Vertical (being the direction of train length) side integral body of cover body 4 is substantially oblong-shaped, the rear and front end of cover body 4 profiles (being the windward side of current of traffic) roughly is parabola shaped, air stream just can upwards flow along obliquely windward side like this, this reduces the resistance of vehicle 3 pairs of air-flows of streamlined reefer housing when high-speed cruising, the noise that produces when reducing streamlined reefer housing 3 itself with windage, simultaneously, also weaken air-flow to the impact of windage brake equipment 2, reduce the noise that windage brake equipment 2 produces.
The height of streamlined reefer housing 3 is higher, the effect of its sound insulation is better, also can corresponding increase running resistance but streamlined reefer housing 3 is too high, so the height of streamlined reefer housing 3 can not be too high can not be excessively low, cross the effect of low out of reach sound insulation, according to the measuring and calculating that vehicle operating is reached to windage brake equipment 2 structures, the height of the distance from top roof 1 of streamlined reefer housing 3 just can satisfy above-mentioned requirements less than 300mm.
Be fixed with many horizontal and vertical reinforcement gussets 6 of crisscross setting at the inwall of cover body 4, horizontal and vertical reinforcement gusset 6 welds or is pasted and fixed on the inwall of cover body 4, strengthening gusset 6 also can be one-body molded with cover body 4, between many horizontal reinforcement gussets 6 and many spacings of strengthening longitudinally between the gusset 6 be respectively 200mm-500mm, to satisfy the strength and stiffness requirement of streamlined reefer housing 3 integral body.
As shown in Figure 6, cover body 4 adopts the interlayer composite material structure, the two-layer employing glass-felt plastic 7 of outside, middle interlayer adopts fabric, in the present embodiment, the intermediate course 8 preferred three dimension stereo fabrics 8 that adopt, the thickness of three dimension stereo fabric 8 is 7mm-10mm, be preferably 8mm, the thickness of glass-felt plastic 7 is between 0.5mm-1mm.This sandwich structure not only can reduce the weight of streamlined reefer housing 3, and this structure is when being hit by foreign matter, and breaking can the radioactivation diffusion, be easy to repair, and three dimension stereo fabric has improved interlaminar shear strength and the anti-damage tolerance of whole composite material.Corresponding with cover body 4, strengthen the material that gusset 6 also preferably adopts glass-felt plastic, one-body molded with cover body 4, be convenient to processing and installation.
Such as Fig. 3 and shown in Figure 5, periphery at cover body 4 has a plurality of mounting grooves 9, mounting groove 9 is rounded and a little less than the outside face of cover body 4, be provided with mounting hole 10 at mounting groove 9, the below of each mounting groove 9 arranges a mount pad (not shown), and mount pad is bolted on the roof 1, and mount pad also can directly be welded on the roof 1, mounting groove 9 is captiveed joint with mount pad by bolt, thereby cover body 4 is fixedly mounted on the roof 1.Suitably reduce the attachment point height of bolt, can increase whole streamlined reefer housing 3 near the strength and stiffness of bottom, in addition, mounting groove 9 all is arranged on horizontal reinforcement gusset 6 and strengthens longitudinally the infall of gusset 6, to increase hard-wired bulk strength.In order to improve installation strength, and be easy to processing, mounting groove 9 adopts intensive properties FPR(fibre-reinforced plastics), it can be pasted and fixed on the cover body 4.
Windage brake equipment 2 is to be fixedly mounted on separately on the roof 1, the top cover outline of the inner ring 5 peripheral distance windage brake equipments 2 of cover body 4 will keep certain gap, the gap remains between the 20mm-70mm, so that demand that can meeting spatial when windage brake equipment 2 is opened, during windage brake equipment 2 closure, streamlined reefer housing 3 and windage brake equipment 2 one integrated mass.
As mentioned above, given scheme content can derive similar technical scheme in conjunction with the accompanying drawings and embodiments.In every case be the content that does not break away from technical solutions of the utility model,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
