Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1, the utility model provides a kind of roof pantograph mounting structure, comprise the groove part 2 for installing pantograph 1 being opened in roof, groove part 2 on the top board 5 of car body, offers one roughly in sagittate opening, former and later two end plates 3 and two side plates 4 are welded with around opening, the bottom of groove part 2 is the steel structure of car roof of car body, base and the steel structure of car roof of end plate 3 and side plate 4 are welded to connect, anterior end plate 3 is the bendable structure coordinating arrowhead form, the wherein top board 5 of roof, the end plate 3 of groove part 2, side plate 4 and steel structure of car roof are all as a part for car body.Pantograph 1 is installed on the inside of the groove part 2 of roof completely, falling in the completely recessed vehicle roof outline line of arciform state pantograph 1, car body surface is given prominence to without any parts, not only realize the aerodynamic performance that vehicle is good, the impact of effective reduction pantograph system flow-induced vibration, the generation of effective minimizing aerodynamics noise, makes the more smooth grace of contour of the vehicle simultaneously.
As depicted in figs. 1 and 2, a base 6 is set in the inside of groove part 2, on base 6, the insulator 7 of corresponding pantograph 1 arranges three mount pads 8, and be mounted by means of bolts on bottom the insulator 7 of pantograph 1 on the mount pad 8 of base 6, base 6 is bolted on steel structure of car roof.Pantograph 1 is fixedly connected with steel structure of car roof by base 6, base 6 plays the effect of transition, not only be beneficial to installation and maintenance, also pantograph 1 can be avoided directly to be connected with the steel structure of car roof of car body, reduce constructional noise, and cut down car external noise to the transmission in car, good absorption Noise Reduction is played to the constructional noise in pantograph region.
In the present embodiment, base 6 preferably adopts the H-shaped framed structure be welded to form by two longerons 9 and two crossbeams 10, not only can ensure its load-carrying capacity, can reduce the overall weight of base 6 simultaneously, meet weight-saving requirement.Three mount pads 8 are weldingly fixed on two crossbeams 10 of base 6, a connecting panel 23 is respectively welded with at the two ends of two crossbeams 10, the steel structure of car roof of base 6 with car body respectively by being bolted on steel structure of car roof, and then is fixed together by four connecting panels 23.
As shown in Figure 2, base 6 is also provided with the clump weight 11 of one or more metal, and clump weight 11 is fixed on base 6 by stud 12.By changing the size of this clump weight 11, the weight of " H " type base 6 can be regulated, software for calculation auxiliary under, to obtain optimum counterweight, reduce constructional noise to greatest extent.
As shown in Figures 2 to 4, between base 6 and the bottom of pantograph 1, one deck insulation board and panel 13 is also set, the shape of insulation board and panel 13 and the mating shapes of groove part 2, and all cover groove part 2, for the ease of installing insulation board and panel 13, the size being dimensioned slightly smaller than groove part 2 of insulation board and panel 13, therefore, in the present embodiment, a circle press strip 26 is also provided with in the border of insulation board and panel 13, press strip 26 is arranged on by bolt on the border of insulation board and panel 13 after insulation board and panel 13 is installed again, in order to regulate insulation board and panel 13 and groove part 2 car body between gap.Insulation board and panel 13 not only plays fine damping of vibrations, better can also completely cut off airborne noise, play good absorption Noise Reduction to the aerodynamics noise in pantograph region.
As shown in Figure 5, insulation board and panel 13 adopts the structure of sandwich, be made up of the sound deadener 16 of upper strata metal sheet 14, lower metal plate 15 and centre, bond between sound deadener 16 and lower metal plate 15 fixing, upper strata metal sheet 14 is pressed on the upper surface of sound deadener 16, finally to be tightened together by the sound deadener 16 of upper strata metal sheet 14, lower metal plate 15 and centre formation sandwich construction with multiple bolt.
The centre portion (region of corresponding base 6) of insulation board and panel 13, on the crossbeam 10 being directly fixed on H-shaped base 6 by multiple bolt 24 and longeron 9, in the two side areas of insulation board and panel 13, be then fixedly connected with the steel structure of car roof of bolt 25 with car body groove part 2 by several vibration proof mountings 22.
As shown in Figure 5, in order to strengthen the Joint strenght between insulation board and panel 13 and steel structure of car roof, the lower surface of insulation board and panel 13 arranges multiple reinforced rib 18, arranged in parallel on the direction of vehicle commander between multiple reinforced rib 18, the section of reinforced rib 18 is inverted U-shaped, its top margin is weldingly fixed on lower metal plate 15 lower surface of insulation board and panel 13, preferably adopts the form of spot welding to be welded and fixed, to reduce welding deformation between reinforced rib 18 and lower metal plate 15.Each reinforced rib 18 arranges multiple vibration proof mounting 22, and vibration proof mounting 22 is fixed together by bolt 25 and reinforced rib 18 and insulation board and panel 13 again.By this mode flexibly connected of vibration proof mounting 22, noise can be reduced further and directly pass to car body, play vibration and noise reducing effect.
In order to improve its soundproof effect further, in the present embodiment, lower metal plate 15 lower surface of insulation board and panel 13 is provided with multiple microwell plate 17 with certain altitude, between every two reinforced ribs 18, all arrange at least one microwell plate 17, microwell plate 17 is the same with reinforced rib 18 arranged in parallel in vehicle commander direction.Microwell plate 17 preferably adopts aluminium matter microwell plate, to reduce the overall weight of insulation board and panel 13, meets weight-saving requirement.As shown in Figure 4 and Figure 5, the section of microwell plate 17 adopts U-shaped, and the both sides of microwell plate 17 are had between flange 19 and the lower metal plate 15 of insulation board and panel 13 and are fixedly connected with by rivet 20.。
Insulation board and panel 13 retains certain interval after mounting and between the steel structure of car roof of car body groove part 2, to avoid the structures such as the microwell plate 17 of insulation board and panel 13 lower surface and reinforced rib 18, and simultaneously can as the drainage channel of groove part 2.
As shown in Figures 2 and 3, the centre of insulation board and panel 13 has three installing ports 21, reinforced rib 18 and microwell plate 17 avoid the position of installing port 21, and three mount pad 8 correspondences on base 6 pass from three installing ports 21, are mounted by means of bolts on mount pad 8 bottom insulator 7.
As mentioned above, plan content given by reference to the accompanying drawings, can derive similar technical scheme.In every case be the content not departing from technical solutions of the utility model, any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
