Abstract
The utility model relates to a low -floor city rail roof structure for vehicle, including the roof board, the roof board comprises at foam core one deck sheet metal all around the foam core and the parcel of centre, through bolt fixed connection between roof board and side wall and the headwall. The utility model discloses a bond the combined material who forms by foam core and sheet metal and make, satisfying under structural strength's the prerequisite, greatly reduced the weight of roof, has also improved greatly simultaneously and has insulated against heat, has fallen the ability of making an uproar, the roof board passes through bolt and side wall and headwall fixed connection in addition, has improved the modularization degree of roof board, satisfies low -floor rail vehicle to lightweight and modular requirements at the higher level, the while also is favorable to outside the car installation of equipment and che nei equipment.
Description
Technical field
The utility model relates to a kind of roof structure of guideway vehicle, particularly a kind of Low-floor urban rail vehicle roof structure, belongs to guideway vehicle manufacturing technology field.
Background technology
The guideway vehicles such as existing EMU, because running velocity is high, in order to reduce vehicle's center of gravity, divide at car and put equipment compartment, most equipment to be all installed under car in equipment compartment, roof, except installing an air-conditioner except unit and pantograph, need not install other main equipment, and the load of bearing required for roof is less.But for low-floor rail vehicles such as city rails, because lower vehicle is not for the installing space that equipment is installed, nearly all equipment all needs to be installed on roof, the load of bearing required for roof is larger, the roof structure of existing guideway vehicle can not meet the needs of low-floor rail vehicle roof needs carrying plurality of devices, and under the prerequisite meeting roof structure intensity, also need to consider guideway vehicle lightweight and modular designing requirement.
Utility model content
The utility model main purpose is to solve the problem and deficiency, provides a kind of degree of modularity high, and lightweight, has the Low-floor urban rail vehicle roof structure of enough load-carrying capacitys.
For achieving the above object, the technical solution of the utility model is:
A kind of Low-floor urban rail vehicle roof structure, comprises roof hoard, and described roof hoard is made up of the foam core material of centre and the layer of metal thin plate that is wrapped in foam core material surrounding, described roof hoard and being bolted to connection between side wall and headwall.
Further, be embedded with mounting nuts in the surrounding of described roof hoard, be fixedly connected with headwall with side wall by bolt.
Further, many are provided with for installing the C shape chute of in-vehicle device and car external equipment in the upper and lower surface of described roof hoard.
Further, fixed by glue between described C shape chute and described roof hoard or rivet fixing or bolt and be connected and fixed.
Further, embed in the middle of described foam core material and install many crossbeams, many described crossbeams be arranged in parallel along width over sides of car body direction.
Further, crossbeam described in every root is provided with the pre-buried slab of polylith, is embedded with the riveting nut for erecting equipment at described pre-buried slab place.
To sum up content, a kind of Low-floor urban rail vehicle roof structure described in the utility model, adopt and be made up of foam core material and the sheet metal composite material formed that bonds, under the prerequisite meeting structural strength, greatly reduce the weight of roof, roof hoard inside adopts high strength foam materials and methods of making, relative to the roof of simple metals structure, also substantially increase heat insulation, noise reduction capability, eliminate the use of damping material, damping slurry, simplify production process.
In the utility model, roof hoard is fixedly connected with headwall with side wall by bolt, improves the degree of modularity of roof hoard, meets low-floor rail vehicle to lightweight and modular requirements at the higher level, is also conducive to the installation of car external equipment and in-vehicle device simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
As shown in Figure 1 to Figure 3, roof hoard 1, foam core material 2, sheet metal 3, mounting nuts 4, C shape chute 5, crossbeam 6, slab 7, riveting nut 8.
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 to Figure 3, a kind of Low-floor urban rail vehicle roof structure, comprises roof hoard 1, and roof hoard 1 is made up of the foam core material 2 of centre and the layer of metal thin plate 3 that is wrapped in foam core material 2 surrounding.In the present embodiment, foam core material 2 preferably adopts high strength foam materials and methods of making.The structure of this roof hoard 1, under the prerequisite meeting structural strength, reduces roof weight to greatest extent, weight only quite and homogenous configuration intensity carbon steel, aluminum alloy roof 2/3, meet the requirement of vehicle weight-saving.Roof inside adopts high strength foam, relative to the roof of simple metals structure, substantially increases heat insulation, noise reduction capability, eliminates the use of damping material, damping slurry, simplify production process.
In the present embodiment, roof hoard 1 and being bolted to connection between side wall and headwall, be embedded with mounting nuts 4 in the surrounding of roof hoard 1, mounting nuts 4 is fixedly connected with headwall with side wall by bolt, install, dismantle very convenient, and also improve the degree of modularity of roof hoard 1, substantially increase installation effectiveness, reduce labour intensity, and roof hoard 1 is not connected with side wall and headwall by traditional welding manner, eliminate the impact of welding deformation, substantially increase the planeness of roof.
In order to improve overall construction intensity and the rigidity of roof hoard 1, to ensure its integrated carrying ability, embed in the middle of foam core material 2 and install many crossbeams 6, many crossbeams 6 be arranged in parallel along width over sides of car body direction, and the section of crossbeam 6 is basin shape.Every root crossbeam 6 is provided with the pre-buried slab 7 of polylith, is embedded with the riveting nut 8 for erecting equipment at pre-buried slab 7 place, the mounting interface of in-vehicle device is provided, ensures enough intensity.
The upper and lower surface of roof hoard 1 is provided with many for installing the C shape chute 5 of in-vehicle device and car external equipment, equipment is bolted on C shape chute 5, C shape chute 5 the installation site facilitating adjustment equipment is set, C shape chute 5 is fixedly connected with by glue with between roof hoard 1, the mode that can also increase riveted joint at necessary place is fixed, or is bolted fixing.
As mentioned above, plan content given by reference to the accompanying drawings, can derive similar technical scheme, as the utility model is also applicable on other guideway vehicle.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.
