Amount.
The technical solution adopted by the present invention：For the vehicle frame of rail of subway grinding machine, there is central sill, the lower end of the central sill
Face is provided with sleeper beam, and one end of the central sill is provided with front beam, and the side of the central sill passes through multiple crossbeams being parallel to each other and side
Beam I is connected, and the opposite side of the central sill is connected by multiple crossbeams being parallel to each other with side bar II, and described one end of side bar I is with before
End carriage one end vertical connection, described one end of side bar II and front beam other end vertical connection, the side bar I and side bar II it is another
End is connected by back end beam with central sill, and the lower surface of the central sill one end is provided with front haulage beam, and the one of the front haulage beam
End is connected with front beam, and the lower surface of described central sill the other end is provided with rear haulage beam.
Wherein, the central sill is mainly thickness >=10mm of a box-structure and its steel plate formed by steel plate splicing.
Further, the side bar I and side bar II are made up of angle bar.
Further, the front beam, front haulage beam and sleeper beam are made up of steel plate and shaped steel splicing.
Further, the crossbeam is the L-type structure formed by steel plate splicing.
Further, the front beam is provided with hitch striker, and the rear haulage beam is provided with draw bar mounting seat.
Further, the side bar I and side bar II are bolted with car body and are integrated.
The present invention compared with prior art the advantages of：
1st, central sill is mainly the box-structure formed by steel plate splicing, and hydraulic pressure unit, dynamical system etc. are main on car
Polished under the installation of equipment and car the installation of dolly, be the main carrier bar of rail grinding machine, have that strength and stiffness are big, weight
The characteristics of light；
2nd, side bar I and side bar II are made of angle bar, only carry the weight of the lighter weight parts such as air pipe line, water pipe
Amount, alleviates vehicle own wt；
3rd, side bar I and side bar II are bolted with car body, and car body constrains in vertical non-displacement, car body is not carried
Weight, no deformation；
4th, using the crossbeam of L-type structure, make side bar I and side bar II be connected with central sill it is relatively reliable firmly.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is Fig. 1 A-A sectional views；
Fig. 3 is Fig. 1 B-B sectional views.
Embodiment
1-3 describes embodiments of the invention below in conjunction with the accompanying drawings.
For the vehicle frame of rail of subway grinding machine, there is central sill 1, the central sill 1 be used for Electric Appliance Cabinet on car, hydraulic pressure unit,
The installation of the suspension equipment such as polishing dolly under the installation of the capital equipments such as dynamical system, water tank and car, it is the master of rail grinding machine
Want carrier bar；One end of the central sill 1 be provided with front beam 2 and front beam 2 can the part such as Vehicle clamp mounting, uncoupling lever bracket, institute
The side for stating central sill 1 is connected by multiple crossbeams 4 being parallel to each other with side bar I 5, and the opposite side of the central sill 1 passes through multiple phases
Mutually parallel crossbeam 4 is connected with side bar II 6, described one end of side bar I 5 and one end vertical connection of front beam 2, the side bar II 61
