The utility model main purpose is to solve the problem and deficiency, provides one to facilitate equipment hoisting Bolt to position, and can meet the Undercarriage structure of the aluminum alloy bodywork of rail vehicle of equipment damping requirement.
For achieving the above object, the technical solution of the utility model is:
A kind of Undercarriage structure of aluminum alloy bodywork of rail vehicle, comprise the hollow extruded aluminum alloy profile be made up of the reinforced rib of top plate, lower plywood and centre, described lower plywood is provided with many guide-track grooves, described guide-track groove fixes equipment under car by lifting bolt, the head of described lifting bolt inserts in described guide-track groove, between described guide-track groove inwall and the head of lifting bolt, be provided with elastomeric material.
Further, described elastomeric material is pasted and fixed on the inwall of described guide-track groove.
Further, described elastomeric material is pasted and fixed on the head of described lifting bolt, is wrapped up by the head of described lifting bolt.
Further, described elastomeric material is rubber or resin.
Further, described guide-track groove is hidden completely or is partly hidden in the inside of described lower plywood.
To sum up content, the Undercarriage structure of a kind of aluminum alloy bodywork of rail vehicle described in the utility model, in guide-track groove and between the head of lifting bolt, elastomeric material is set, lifting bolt is only had just to slide in guide-track groove under external force, under the effect not having external force, relatively by guide-track groove and lifting bolt and the friction force between elastomeric material fixingly lift bolt, avoid it to slide arbitrarily, the positioning difficulty of the lifting bolt greatly reduced, time saving and energy saving.In addition, due to the setting of elastomeric material, also reduce the fastening rigidity between lifting bolt and guide-track groove, reach to the effect of equipment damping.And the guide-track groove of original hollow extruded aluminum alloy profile hold-down bolt redesigns by the utility model, outstanding guide-track groove is designed to completely concealed or half hidden structure, add space under car, facilitate equipment to install, improve the alerting ability of stringing, wiring.

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:
Embodiment one:
As shown in Figure 1, the utility model provides a kind of Undercarriage structure of aluminum alloy bodywork of rail vehicle, comprise by top plate 1, the hollow extruded aluminum alloy profile of reinforced rib 3 composition of lower plywood 2 and centre, cavity between top plate 1 and lower plywood 2 is separated into multiple die cavity 4 by reinforced rib 3, the installing floor board face, top of top plate 1, lower plywood 2 is provided with many elongated guide-track grooves 5, guide-track groove 5 direction along ng a path be arranged in parallel, guide-track groove 5 fixes equipment (not shown) under car by lifting bolt 8, when under car, equipment is installed, the head of lifting bolt 8 inserts in guide-track groove 5, slided with the installation site of conditioning equipment in guide-track groove 5 by lifting bolt 8.
In the present embodiment, guide-track groove 5 is the C type groove under shed, and guide-track groove 5 is hidden in the inside of lower plywood 2 completely, and the opening 6 of guide-track groove 5 is in same plane with the lower surface of lower plywood 2, guide-track groove 5 and top plate 1, lower plywood 2 and reinforced rib 3 one extrusion forming.
Guide-track groove 5, greatly about 20mm-30mm, is hidden in the inside of lower plywood 2 by the height of guide-track groove 5 completely, is equivalent to height space under car being added 20mm-30mm, facilitates the installation of equipment under car, improves the alerting ability of stringing, wiring.
Elastomeric material 7 is provided with between guide-track groove 5 inwall and the head of lifting bolt 8, elastomeric material 7 preferably adopts rubber or resin, as shown in Figure 2, in the present embodiment, elastomeric material 7 is pasted and fixed on the inwall of guide-track groove 5, elastomeric material 7 surrounds a C type groove, and the head of lifting bolt 8 is inserted in the C type groove that surrounded by elastomeric material 7.
Owing to there is certain friction force between lifting bolt 8 and elastomeric material 7, lifting bolt 8 is only had just to slide in guide-track groove 5 under external force, when there is no External Force Acting, lifting bolt 8 can not rock arbitrarily because of the existence of friction force in guide-track groove 5, plays relatively-stationary effect, therefore, greatly reduce the positioning difficulty of lifting bolt 8, and before can be implemented in equipment installation, locate in advance hanger bolt 8, time saving and energy saving.In addition, due to the setting of elastomeric material 7, when erecting equipment, by the rubber in extruding guide-track groove 5 or resin, reduce the fastening rigidity between lifting bolt 8 and guide-track groove 5, reach to the effect of equipment damping.
Embodiment two:
As shown in Figure 3, be with embodiment one difference, in the present embodiment, elastomeric material 7 be pasted and fixed on the head of hanger bolt 7, the head of lifting bolt 8 is wrapped up completely.The head of the lifting bolt 8 of parcel rubber or resin inserts in guide-track groove 5, mobile in guide-track groove 5 according to equipment attachment point.
Owing to there is certain friction force between the inwall of guide-track groove 5 and elastomeric material 7, lifting bolt 8 is only had just to slide in guide-track groove 5 under external force, when there is no External Force Acting, lifting bolt 8 can not slide arbitrarily because of the existence of friction force in guide-track groove 5, therefore, the positioning difficulty of the lifting bolt 8 greatly reduced, and before can be implemented in equipment installation, locate in advance hanger bolt 8, time saving and energy saving.In addition, due to the setting of elastomeric material 7, when erecting equipment, by the rubber in extruding guide-track groove 5 or resin, reduce the fastening rigidity between lifting bolt 8 and guide-track groove 5, reach to the effect of equipment damping.
Embodiment three:
As shown in Figure 4, be with embodiment one and embodiment two difference, in the present embodiment, guide-track groove 5 some be hidden in the inside of lower plywood 2, another part protrudes from the lower surface of lower plywood 2, the height of hidden parts can according to different automobile types, distinct device designs separately, guide-track groove 5 is similarly the C type groove under shed, the opening 6 of guide-track groove 5 is positioned at the below of lower plywood 2, although this structure only has part guide rails groove 5 to be hidden in the inside of lower plywood 2, but space under also relatively can increasing car, better can ensure the planeness of equipment attachment face under car simultaneously.Elastomeric material 7 is provided with between the inwall and the head of lifting bolt 8 of guide-track groove 5.
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.
