Abstract
The utility model provides a high -speed EMUs bottom plate anticreep device which characterized in that: including bolt constitution and mount pad two parts, the bolt is constituteed and is linked to each other with the bottom plate, and the mount pad links to each other with the hinge, and bolt constitution and mount pad interconnect simultaneously, including bolt, bolt seat, spring during the bolt is constituteed, bolt seat lower part be with the bottom plate on the inclined plane that matches of plane phase, bolt and spring adorn in the bolt seat with the telescopic fixed connection of bolt seat, mount pad side is the form of opening one's mouth, the bolt stretch into the mount pad open one's mouth in through the screw connection mount pad. The utility model discloses a bolt is constituteed and to be linked to each other with the bottom plate, and the mount pad links to each other with the hinge, bolt and spring dress in the bolt seat with the telescopic fixed connection of bolt seat, the mount pad side is the form of opening one's mouth, the bolt stretch into the mount pad open one's mouth in through the screw connection mount pad, solved the be connected problem of anticreep device with arc glass steel bottom plate, realized the fixed of bolt contraction state, reduce the operation degree of difficulty for workman mounting plate, the assurance bottom plate moves the in -process in abnormal conditions and can not drop.
Description
Technical field
The utility model relates to a kind of guideway vehicle base plate anti-drop device.
Background technology
Under most of key equipment of high speed train is lifted on car, when train on the line high-speed cruising time can produce very strong air pressure wave and very large air resistance, and the situation that stone, ice cube or other object and high-speed train divide into standby meet accident high-speed crash and strike occurs often.For reducing air resistance, protecting and equipment under tool car, guaranteeing the safe operation of EMU, the car lower bottom part of the EMU of Speed 200 km/h and above speed class arranges the base plate possessing water conservancy diversion, protection, maintenance function.
CRH5 EMUs base plate and car body attachment adopt bolt fixed connection structure.If loosening appears in bed bolt in train high-speed cruising process, base plate is caused to come off, by the safe in operation of entail dangers to train.Therefore, need on base plate, increase a kind of anti-drop device, ensure that bed bolt all loosens situation lower shoe and can not come off.At present, CRH3 type motor train unit base plate realizes anticreep by increasing base plate latch, be made up of latch, plug housing, socket bolt, spring four part, latch contraction can be made to enter in plug housing by stirring socket bolt during mounting base, base plate unclamps bolt after being lifted to accurate location, latch springs in support position of opening automatically, namely completes the installation of base plate anti-drop device.But there is two problems in it: one is to realize the connection with CRH5 type car arc glass back of half bearing shell; Two is that latch contraction state cannot be located.
Utility model content
The purpose of this utility model is to provide one and is adapted to CRH5 EMUs car bottom plate anti-drop device, improves the safety of train operation.
For achieving the above object, the utility model provides a kind of EMU base plate anti-drop device, it is characterized in that: comprise latch composition and mount pad two parts, and latch composition is connected with base plate, mount pad is connected with hinge, and latch composition and mount pad are connected to each other simultaneously; Latch composition comprises latch, plug housing, spring, and plug housing bottom is the inclined-plane matched with plane on base plate, and latch and spring are contained in plug housing and are fixedly connected with plug housing is telescopic; Mount pad side is the form of dehiscing, and latch stretches into during mount pad is dehisced and is connected by screw mount pad.
Plug housing and mount pad bottom aerofoil have slotted hole, and slotted hole direction on plug housing and mount pad bottom aerofoil is orthogonal.
The utility model is connected with base plate by latch composition, mount pad is connected with hinge, latch and spring are contained in plug housing and are fixedly connected with plug housing is telescopic, mount pad side is the form of dehiscing, latch stretches into during mount pad is dehisced and is connected by screw mount pad, solves the connectivity problem of anti-drop device and arc glass back of half bearing shell, achieves the fixing of latch contraction state, reduce operation easier to workman's mounting base, ensure that base plate can not come off in abnormal condition operational process.
Accompanying drawing explanation

Fig. 2 is the utility model mounting structure schematic diagram;
Fig. 3 is the utility model opening schematic diagram;
Fig. 4 is the utility model locking states schematic diagram.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, the utility model comprises latch 3, plug housing 7, spring 6 and mount pad 1, plug housing bottom is the inclined-plane matched with plane on base plate, latch and spring are contained in plug housing, latch is arranged two socket bolts 4,5, after pulling down one of them bolt, latch can take in plug housing, then the bolt pulled down is loaded in another hole, the fixing of latch contraction state can be realized.Mount pad side is the form of dehiscing, latch is stretched into during mount pad is dehisced and is connected by screw 2, plug housing 7 and base plate 9 are through being connected through the bolt 11 of four slotted holes on aerofoil bottom plug housing, backing plate 10 is housed between base plate lower surface and nuts, adjust latch height by adjusting pad 8 between plug housing and plate upper surface, mount pad 1 is connected with the bolt 13 and spring cotter 14 of hinge 12 through passing four slotted holes on mount pad lower aerofoil.The slotted hole direction of plug housing and mount pad being worn bolt is orthogonal, latch and mount pad can be adjusted in direction up and down, ensure that anti-drop device still can be installed smoothly when base plate, hinge reach maximum build-up tolerance situation.
With reference to Fig. 3, before base plate entrucking, latch is in contraction state, non-hold-down bolt on mount pad.
With reference to Fig. 4, after base plate entrucking, pulled down by the socket bolt of on latch, the socket bolt pulled down installs after ejecting by spring elongates latch, is then installing on mount pad by bolt, is namely achieving the connection of anti-drop device.
