Abstract
Equipment mounting structure under a kind of city rail vehicle underframe, comprise underframe (1), the both sides of this underframe are provided with edge beam of underframe (2), arrange C type groove (3) below two edge beam of underframes respectively, are provided with multiple first mount pad (4) in C type groove; The both sides of equipment (5) arrange multiple second mount pad (51), and the second mount pad of equipment both sides is fixedly connected on the first mount pad that two edge beam of underframes are arranged respectively below.The utility model, by arranging C type groove and erecting equipment under edge beam of underframe, significantly can reduce the stress of mounting structure, reduces the distortion of mounting structure, thus greatly improves the strength and stiffness of heavy wares mounting structure.
Description
Technical field
The utility model relates to a kind of city rail vehicle equipment mounting structure, particularly equipment mounting structure under a kind of city rail vehicle underframe.
Background technology
City rail vehicle is passenger-carrying vehicle, and be that passenger takes space in car, large number quipments can only be arranged on outside car.Because the strength and stiffness of vehicle body side wall and headwall are lower, the top outside car generally only installs an air-conditioner equipment, and large number quipments all hangs over below underframe.As shown in Figure 1, the equipment 4 ' hung over below underframe is all be arranged in the C type groove 2 ' of underframe 1 ' below by equipment mount pad 3 ' usually, although the bottom frame floor forming underframe is hollow material, inside is furnished with reinforced rib, but bottom frame floor section bar wall thickness is little, and intensity is low, rigidity is little, once hang the above main equipment that to weigh tonne, the static stress and distortion that installation position generation is larger can be caused, time serious, also can cause undercapacity.
Utility model content
Technical problem to be solved in the utility model is, not enough for prior art, there is provided equipment mounting structure under a kind of city rail vehicle underframe, it can improve the strength and stiffness of heavy wares installation position under underframe, thus the reliability that under improving city rail vehicle underframe, equipment is installed and safety.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: equipment mounting structure under a kind of city rail vehicle underframe, comprises underframe, and the both sides of this underframe are provided with edge beam of underframe, C type groove is set below two edge beam of underframes respectively, in C type groove, is provided with multiple first mount pad; The both sides of equipment arrange multiple second mount pad, and the second mount pad of equipment both sides is fixedly connected on the first mount pad that two edge beam of underframes are arranged respectively below.
The top of this first mount pad is provided with and is multiplely a straight-though arrangement and can the slide block of sliding sleeve in C shape groove, and this first mount pad top panel is provided with multiple fixed orifice, the bottom panel of C shape groove is provided with multiple screw, after connecting locking by bolt or latching device between fixed orifice and screw, slide block is fixed in the C shape groove under edge beam of underframe; The bottom of this first mount pad is provided with equipment supporter, and the second mount pad of equipment is put and is fixed on this equipment supporter.
The mounting means of heavy wares under the utility model change city rail vehicle underframe, directly installs heavy wares to change into and installs through edge beam of underframe from traditional bottom frame floor.Because edge beam of underframe depth of section is much larger than bottom frame floor depth of section, and edge beam of underframe profile wall thickness rate bottom frame floor section bar wall thickness is large, the strength and stiffness of edge beam of underframe are much higher than the strength and stiffness of bottom frame floor, in the C type groove that heavy wares is arranged on below edge beam of underframe compared in the C type groove be installed on below bottom frame floor, significantly can reduce the stress of mounting structure, reduce the distortion of mounting structure, thus greatly improve the strength and stiffness of heavy wares mounting structure, the reliability that the equipment under city rail vehicle underframe that improves is installed and safety.

Detailed description of the invention
As shown in Figure 2, under the utility model city rail vehicle underframe, equipment mounting structure one embodiment comprises underframe 1, and the both sides of this underframe 1 are provided with edge beam of underframe 2, and two edge beam of underframes 2 arrange respectively in C type groove 3, C type groove 3 below and are provided with multiple first mount pad 4.The both sides of equipment 5 arrange multiple second mount pad 51, and equipment 5 just can be installed on underframe 1 time by the first mount pad 4 that the second mount pad 51 of equipment 5 both sides is fixedly connected on two edge beam of underframes 2 respectively.
As shown in Figure 3, the top of this first mount pad 4 is provided with and is multiplely a straight-though arrangement and can the slide block 41 of sliding sleeve in C shape groove 3.This first mount pad 4 top panel is provided with multiple fixed orifice 42, and the bottom panel of C shape groove 3 is provided with multiple screw (not shown), be connected and fixed hole 42 and screw by bolt or latching device, slide block 41 can be fixed in the C shape groove 3 under edge beam of underframe 2.The bottom of this first mount pad 4 is provided with equipment supporter 43, and the second mount pad 51 of equipment 5 is seated on this equipment supporter 43, and is bolted, and can realize the installation of equipment 5.This slide block 41 is preferably bolt cap bolt upward.
