Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
As depicted in figs. 1 and 2, in the intercity guideway vehicle of part, often save the top in compartment 15 and be provided with two overhead Air conditioning unit 1, the position of the unit 1 that the car body 16 of roof needs install an air-conditioner has rectangle mounting shaft 2, and air-conditioner set 1 is installed in this mounting shaft 2.
At each mounting shaft 2 place, border along mounting shaft 2 arranges a ringwise frame-type car body mount pad 3, car body mount pad 3 adopts aluminium section bar welding to form, aluminium section bar is weldingly fixed on car body 16, can ensure that the intensity of car body mount pad 3 can ensure the leak tightness between car body mount pad 3 and car body 16 simultaneously like this.Because roof is curved, so the shape and size of car body mount pad 3 will match with the car body 16 at mounting shaft 2 place, car body mount pad 3 side being positioned at air-conditioner set 1 both sides is linear pattern, the side being positioned at air-conditioner set 1 rear and front end is arc, ensures that setting accuracy ensures the leak tightness of installing simultaneously.
With car body mount pad 3 correspondingly, the housing 14 of air-conditioner set 1 is installed with ringwise frame-type units' installation seat 4, and units' installation seat 4 adopts equally aluminium section bar welding to form.The shape of units' installation seat 4 and size and car body mount pad 3 match, and are arc at the side of the units' installation seat 4 being positioned at air-conditioner set 1 rear and front end.The aluminium section bar of units' installation seat 4 preferably adopts the mode of welding to be fixed on the housing 14 of air-conditioner set 1, or be fixedly connected with the housing 14 of air-conditioner set 1 by fasteners such as bolts, when using fastener to connect, between section bar and housing 14, need the air-tightness ensureing vehicle.Car body mount pad 3 and units' installation seat 4 adopt aluminium section bar not only can improve bulk strength, are conducive to the sealing realized between section bar and section bar simultaneously, and then ensure the air-tightness of whole mounting structure.Adopt aluminium section bar to also help processing, and ensure the setting accuracy of whole mounting structure easily through process means, and then meet the requirement of vehicle to setting accuracy.
Be fixedly connected with by multiple hold-down bolt 5 between car body mount pad 3 with units' installation seat 4, hold-down bolt 5 preferably adopts socket bolt, because roof is curved, the rear and front end of air-conditioner set 1 not easily passs through bolt and is fixedly connected with, as shown in Figure 3, in the present embodiment, be only respectively fixedly connected with by multiple hold-down bolt 5 in the both sides of air-conditioner set 1, preferably every side adopts 5 hold-down bolts 5 to be fixedly connected with.
As shown in Figure 4, on car body mount pad 3, needing the position of installing hold-down bolt 5, having the unthreaded hole for inserting hold-down bolt 5.On units' installation seat 4, needing the position of installing hold-down bolt 5, having the unthreaded hole for inserting hold-down bolt 5.In order to fixedly secure, the position of installing hold-down bolt 5 is needed each, one check screw seat 6 is set, check screw seat 6 has the internal thread hole coordinated with hold-down bolt 5, check screw seat 6 preferably adopts stainless steel material, be fixed together by hold-down bolt 5 and check screw seat 6 between car body mount pad 3 and units' installation seat 4, thus air-conditioner set 1 is fixedly secured on car body 16.
As shown in Figure 4, for ensureing setting accuracy, conveniently construct simultaneously, the surface contacted between car body mount pad 3 with units' installation seat 4 is arranged one or more pairs of locating dowel pin (not shown) and knock hole 13, in the present embodiment, diagonal positions is provided with two pairs of locating dowel pins and knock hole 13.When mounted, first find the position of locating dowel pin and knock hole 13 accurately, inserted by locating dowel pin in corresponding knock hole 13, now, car body mount pad 3 and units' installation seat 4 will automatic alignings, and fitting operation is very simple and convenient.
As shown in Figure 4, car body mount pad 3 and the surrounding of units' installation seat 4 are provided with ringwise first hermetically-sealed construction, by the gap seals between two section bars, ensure the air-tightness of whole mounting structure.First hermetically-sealed construction comprises the suitable and packing seal 7 that thickness is suitable of the circle elasticity being fixed on units' installation seat 4 surrounding, the surrounding of units' installation seat 4 have a circle towards under circular groove, packing seal 7 is pasted and fixed in the circular groove of units' installation seat 4.The aluminium section bar of circular groove and units' installation seat 4 is one-body molded, also can be welded on separately on units' installation seat 4.In the surrounding of car body mount pad 3, there is at least one circle annular protrusion 8, for ensureing sealing property, preferably adopting in the present embodiment and two circle annular protrusions 8 are set on car body mount pad 3.After hold-down bolt 5 is tightened, be crimped together tightly between annular protrusion 8 and packing seal 7, thus realize the sealing between car body mount pad 3 and units' installation seat 4.In the rear and front end of air-conditioner set 1, after hold-down bolt 5 is tightened, rely on the gravity of air-conditioner set 1 itself, realize sealing by crimping between annular protrusion 8 with packing seal 7 simultaneously.
In order to prevent leaking gas from hold-down bolt 5, between hold-down bolt 5 and units' installation seat 4, be also provided with the second hermetically-sealed construction.Second hermetically-sealed construction comprises a packing ring 9, packing ring 9 preferably adopts corrosion-resistant steel packing ring, be inlaid with an O-ring seals 10 in the bottom of packing ring 9 around hold-down bolt 5, after hold-down bolt 5 is tightened, O-ring seals 10 is out of shape and is sealed by the upper surface of the bottom of packing ring 9 and units' installation seat 4.
Also be provided with one or more layers rubber gasket 11 above packing ring 9 and between the head of hold-down bolt 5, this rubber gasket 11, by the gap seals between the head of hold-down bolt 5 and packing ring 9, prevents from leaking gas from hold-down bolt 5 further.
Finally, in order to further strengthen air-tightness, as shown in Figure 4, one seal cover cap 12 is set on the top of hold-down bolt 5 again, the inside face of seal cover cap 12 has a circle negative thread, and the upper surface of packing ring 9 is provided with a circle boss 17, and the outside face of boss 17 is provided with the outside thread of a circle and above-mentioned screw-internal thread fit, tighten between seal cover cap 12 and boss 17 and realize sealing, the head of hold-down bolt 5 and rubber gasket 11 seal by seal cover cap 12 completely.Seal cover cap 12 can select the stainless steel material identical with packing ring 9, also can select other material.By above-mentioned multi-sealed, make this mounting structure can meet vehicle completely to bubble-tight stricter requirement, and then the traveling comfort that raising passenger takes.
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 solution of the present invention, any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
