As shown in Figures 1 to 4, upper head-shield 1, lower head-shield 2, car body 3, pilot 4, cut-off rule 5, cut-off rule 6, car body plate-girder 7, slot 8, inserted block 9, rubber pad 10, upper mount pad 11, bolt 12, lower mount pad 13, bolt 14, adjusts pad 15, and spring washer 16 is adjusted pad 17.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail:
As shown in Figure 1, the hood structure of high speed train headstock of the present invention, integral cutting becomes upper and lower two parts, is respectively head-shield 1 and lower head-shield 2.Consider train monnolithic case and car door size, the cut-off rule 5 between upper head-shield 1 and lower head-shield 2 is arranged on to the cut-off rule position between car body 3 and pilot 4, and cut-off rule 6 smooth transition between car body 3 and pilot 4.
Convenient for Assembly &Disassembly, to realize in the outside installation of car body, between upper head-shield 1 and lower head-shield 2, by the mutual socket connection of connected structure, upper head-shield 1 is fixedly connected with the car body plate-girder 7 that is positioned at car body leading section both sides, and lower head-shield 2 is fixedly connected with pilot 4.
As shown in Figure 2, the connected structure between upper head-shield 1 and lower head-shield 2, for being separately positioned on the slot cooperatively interacting 8 and the inserted block 9 on upper head-shield 1 and lower head-shield 2.In the present embodiment, inserted block 9 is for being arranged on the inwardly flanging of turnover of head-shield 1 bottom, inserted block 9 is arranged on the dual-side of head-shield 1 bottom, 8 of slots are for protruding from the structure that the section at lower head-shield 2 tops is U-shaped, slot 8 is to inner opening, slot 8 is arranged on the dual-side at lower head-shield 2 tops, guarantees that inserted block 9 can successfully insert in slot 8.When mounted, the inserted block 9 on upper head-shield 1 inserts in slot 8, and is pushed into desired location along slot 8, and then realizes the socket connection between upper head-shield 1 and lower head-shield 2.For avoid upper head-shield 1 and lower head-shield 2 when mounted rigidity contact, in the present embodiment, paste one deck rubber pad 10 at the upper surface of inserted block 9.Slot 8 and inserted block 9 also can adopt other connected structure form, if the bottom at upper head-shield 1 is to the projecting inward slot for opening downwards that arranges, correspondingly at the top of lower head-shield 2 inserted block 9 etc. that arranges protruding upward.
As shown in Figure 3, on car body plate-girder 7, be welded with multiple on mount pad 11, upper head-shield 1 is fixedly connected with upper mount pad 11 by bolt 12 fasteners such as grade, thereby upper head-shield 1 and car body 3 are fixed together.Cushioning spring washer 16 between upper mount pad 11 and upper head-shield 1, guarantees fixation, guarantees that the long-term upper head-shield 1 in service of train is connected reliably with car body plate-girder 7.Cushioning is adjusted pad 17 simultaneously, may be because of the gap of manufacturing, installation error produces for regulating.
As shown in Figure 4, be fixed with multiple lower mount pads 13 on pilot 4, lower head-shield 2 is fixedly connected with lower mount pad 13 by bolt 14 fasteners such as grade, thereby lower head-shield 2 is fixed together with pilot 4.Bolt 14 selects the self-locking of two HARD-LOCK nuts to fix, and guarantees that the long-term lower head-shield 2 in service of train is connected reliably with pilot 4.Between lower mount pad 13 and lower head-shield 2, cushioning is adjusted pad 15, may be because of the gap of manufacturing, installation error produces for regulating.
As shown in Figures 2 and 3, upper head-shield 1 adopts the sandwich structure being made up of inside panel, exterior skin and middle core, and wherein, middle core adopts the thick T90 foam core of 20mm, exterior skin adopts the thick carbon fiber composite material of 3mm, and inside panel adopts the thick carbon fiber composite material of 4mm.
As shown in Figure 2 and Figure 4, lower head-shield 2 also adopts the sandwich structure being made up of inside panel, exterior skin and middle core, wherein, middle core adopts the thick T90 foam core of 30mm, exterior skin adopts the thick carbon fiber composite material of 4mm, inside panel adopts the thick carbon fiber composite material of 2mm, re-lays the aramid fiber composite material that one deck 2mm is thick on the carbon fiber composite material of inside panel.
Upper head-shield 1 and lower head-shield 2 adopt the sandwich structure of this carbon fiber composite material and foam composition, not only can guarantee the bulk strength of head-shield 1 and lower head-shield 2, the overall weight that can as much as possible reduce upper head-shield 1 and lower head-shield 2 simultaneously, meets the requirement that high speed train is more and more higher to lightweight.
The installation method of describing the hood structure of high speed train headstock below in detail, specifically comprises the steps:
Steps A, first lower head-shield 2 is laid and put in place, be fixed together by bolt 14 and the lower mount pad 13 being weldingly fixed on pilot 4.Step B, upper head-shield 1 is pushed along lower head-shield 2 by connected structure.
Step C, reach behind desired location when upper head-shield 1, be fixed together by bolt 12 and the upper mount pad 11 being weldingly fixed on car body plate-girder 7, form complete head-shield.
When dismounting, by above-mentioned contrary order dismounting.
This hood structure is simple, overall appearance is effective, and in the time that extraordinary circumstances need to realize with other coupling of vehicles, installing/dismounting is all very convenient, after dismounting, upper head-shield 1 and lower head-shield 2 are because volume is relatively little, and the compartment that also can put into train moves with car, realize train and connect extension, rescue function, the transportation of head-shield is also very convenient.This hood structure can also realize by outside and installing, solved due to the inner installing space of car body limits to the head-shield bringing cannot installation question.
As mentioned above, given scheme content, can derive similar technical scheme in conjunction with the accompanying drawings and embodiments.In every case be the content that does not depart from technical solution of the present invention, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present invention, all still belong in the scope of technical solution of the present invention.
