The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
As depicted in figs. 1 and 2, in the intercity guideway vehicle of part, the top in every joint compartment 15 is provided with two overhead unitary air conditioner units 1, and the position of the unit 1 that needs to install an air-conditioner on the car body 16 of roof has rectangle mounting shaft 2, and air-conditioning unit 1 is installed in this mounting shaft 2.
At each mounting shaft 2 place, border along mounting shaft 2 is provided with a ringwise frame-type car body mount pad 3, car body mount pad 3 adopts the aluminium section bar welding to form, aluminium section bar is weldingly fixed on the car body 16, and the intensity that can guarantee car body mount pad 3 like this can guarantee simultaneously the leak tightness between car body mount pad 3 and the car body 16.Because roof is curved, so the shape and size of car body mount pad 3 will be complementary with the car body 16 at mounting shaft 2 places, car body mount pad 3 sides that are positioned at air-conditioning unit 1 both sides are linear pattern, the side that is positioned at air-conditioning unit 1 rear and front end is an arc, guarantees that setting accuracy guarantees the leak tightness of installing simultaneously.
With car body mount pad 3 correspondingly, on the housing 14 of air-conditioning unit 1, be installed with ringwise frame-type unit mount pad 4, unit mount pad 4 is same to adopt the aluminium section bars welding to form.The shape of unit mount pad 4 and size and car body mount pad 3 are complementary, and are arc at the side of the unit mount pad 4 that is positioned at air conditioner group 1 rear and front end.The aluminium section bar of unit mount pad 4 preferably adopts the mode of welding to be fixed on the housing 14 of air-conditioning unit 1, perhaps captive joint with the housing 14 of air-conditioning unit 1 by fasteners such as bolts, when using fastener to connect, need to guarantee the air-tightness of vehicle between section bar and the housing 14.Car body mount pad 3 and unit mount pad 4 adopts aluminium section bars not only can improve bulk strength, helps realizing the sealing between section bar and the section bar simultaneously, and then guarantees the air-tightness of whole erection structure.Adopt aluminium section bar to also help processing, and be easy to guarantee the setting accuracy of whole erection structure, and then satisfy the requirement of vehicle setting accuracy by process means.
Captive joint by a plurality of hold-down bolts 5 between car body mount pad 3 and the unit mount pad 4, the hold-down bolt 5 preferred socket bolts that adopt, because roof is curved, the rear and front end of air-conditioning unit 1 is difficult for being bolted to connection, as shown in Figure 3, in the present embodiment, only respectively pass through a plurality of hold-down bolt 5 captive joints in the both sides of air-conditioning unit 1, preferred every side adopts 5 hold-down bolt 5 captive joints.
As shown in Figure 4, on car body mount pad 3, need to install the position of hold-down bolt 5, have the unthreaded hole that is used to insert hold-down bolt 5.On unit mount pad 4, need to install the position of hold-down bolt 5, have the unthreaded hole that is used to insert hold-down bolt 5.In order to fixedly secure, at each the position of hold-down bolt 5 need be installed, one check screw seat 6 is set, have the internal thread hole that cooperates with hold-down bolt 5 on the check screw seat 6, the check screw seat 6 preferred stainless steel materials that adopt, be fixed together by hold-down bolt 5 and check screw seat 6 between car body mount pad 3 and the unit mount pad 4, thereby air-conditioning unit 1 is fixedly secured on car body 16.
As shown in Figure 4, for guaranteeing setting accuracy, construction for convenience simultaneously, one or more pairs of locating dowel pin (not shown)s and knock hole 13 are set on contacted surface between car body mount pad 3 and the unit mount pad 4, in the present embodiment, be provided with two pairs of locating dowel pins and knock hole 13 in diagonal positions.When mounted, at first find the position of locating dowel pin and knock hole 13 accurately, locating dowel pin is inserted in the corresponding positioning hole 13, at this moment, car body mount pad 3 and unit mount pad 4 will align automatically, and fitting operation is very simple and convenient.
As shown in Figure 4, around car body mount pad 3 and unit mount pad 4, be provided with ringwise first hermetically-sealed construction,, guarantee the air-tightness of whole erection structure the sealing of the space between two section bars.First hermetically-sealed construction comprises a circle packing seal 7 that elasticity is suitable and thickness is suitable that is fixed on around the unit mount pad 4, have around the unit mount pad 4 circle towards under circular groove, packing seal 7 is pasted and fixed in the circular groove of unit mount pad 4.The aluminium section bar of circular groove and unit mount pad 4 is one-body molded, also can be welded on separately on the unit mount pad 4.Around car body mount pad 3, have at least one circle annular protrusion 8, two circle annular protrusions 8 are set on car body mount pad 3 for guaranteeing sealing property, preferably adopting in the present embodiment.After hold-down bolt 5 was tightened, annular protrusion 8 was crimped between packing seal 7 tightly, thereby realized the sealing between car body mount pad 3 and the unit mount pad 4.In the rear and front end of air-conditioning unit 1, after hold-down bolt 5 is tightened, rely on the gravity of air-conditioning unit 1 itself, realize sealing by annular protrusion 8 and crimping between the packing seal 7 simultaneously.
In order to prevent between hold-down bolt 5 and unit mount pad 4, also to be provided with second hermetically-sealed construction from hold-down bolt 5 gas leakage.Second hermetically-sealed construction comprises a packing ring 9, the packing ring 9 preferred corrosion-resistant steel packing rings that adopt, bottom at packing ring 9 is inlaid with an O-ring seals 10 around hold-down bolt 5, and after hold-down bolt 5 was tightened, O-ring seals 10 distortion were with the bottom of packing ring 9 and the upper surface sealing of unit mount pad 4.
Also be provided with one or more layers rubber gasket 11 above the packing ring 9 and between the head of hold-down bolt 5, this rubber gasket 11 further prevents the head and the sealing of the space between the packing ring 9 of hold-down bolt 5 from hold-down bolt 5 gas leakage.
At last, in order further to strengthen air-tightness, as shown in Figure 4, on the top of hold-down bolt 5 seal cover cap 12 is set again, the inside face of seal cover cap 12 has a circle negative thread, is provided with a circle boss 17 at the lower surface of packing ring 9, 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 the boss 17 and realize sealing, seal cover cap 12 seals the head and the rubber gasket 11 of hold-down bolt 5 fully.Seal cover cap 12 can be selected the stainless steel material identical with packing ring 9, also can select other material.By above-mentioned multi-sealed, make this mounting structure can satisfy vehicle fully, and then improve the traveling comfort that the passenger takes bubble-tight more exacting requirements.
As mentioned above, given in conjunction with the accompanying drawings 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.
