With being connected and fixed；The heel end opposite sides face of the heart rail is equipped with wavy shaped configuration, so that the heel end of the heart rail is with respect to two
Side deliberately rail wavy shaped configuration face；The one side of heel end of the fork with rail level to the heart rail is equipped with wavy shaped configuration, with
Make the one side of heel end of the fork with rail level to the heart rail at fork with rail wavy shaped configuration face；The heart rail wavy shaped configuration
Face and the fork are with rail wavy shaped configuration face；The heel end opposite sides face of the heart rail and the fork are with leading between the head of rail
It crosses the heart rail wavy shaped configuration face and the fork and realizes closely connected connection with the cooperation in rail wavy shaped configuration face, and pass through fastener
It is locked.
Fixed combined frog crossing point rail bindiny mechanism, in which: the bindiny mechanism further includes interval iron；The interval
Iron clamp is located between the one side of heel end and the medial surface of the wing rail of the fork with rail backwards to the heart rail and passes through fastening
Part is locked.
Fixed combined frog crossing point rail bindiny mechanism, in which: the fork is to be passed through tightly by a pair of of single tine with rail with rail
Firmware is formed by fixedly connecting；Each single tine is equipped with the wave towards the one side of the heel end of the heart rail with the head of rail
Shape structure.
Fixed combined frog crossing point rail bindiny mechanism, in which: the heart rail is between described wing rail one end, point
End is fixedly connected by fastener with the wing rail.
Fixed combined frog crossing point rail bindiny mechanism, in which: the fastener is connected by screw bolts pair, the bolt
Auxiliary connection is made of screw rod and nut.
The utility model has the advantages that
The design of the utility model fixed combined frog crossing point rail bindiny mechanism's structure is simple, reasonable, and the heel end of heart rail is opposite
Two sides and fork are with using heart rail wavy shaped configuration face close with the cooperation realization in rail wavy shaped configuration face with fork between the head of rail
Patch is connected and is locked by fastener, and this heart rail wavy shaped configuration face and fork are with rail wavy shaped configuration face system easy to process
It makes, especially heart rail wavy shaped configuration face and fork is equal with the closely connected mating surface stress of waveform formed after the cooperation of rail wavy shaped configuration face
It is even, avoid stress concentration, improve the position stress, can effectively prevent heart rail and fork with rail because plateau railway exist compared with
Big rail temperature force and the relative motion generated, that is, solve heart rail and fork with rail because there are larger rail temperature forces for plateau railway
And phenomenon of pulling open or grind one's teeth is generated, the overall stability of plateau railway structure is enhanced, maintenance frequency is reduced, improves combination
Railway frog service life and operation safety meet gapless track requirement, have ensured railroad embankment safety.
