Description
Technical field
The utility model relates to rail maintenance fields, more particularly to rail system at a kind of tie rod and track switch.
Background technique
With increasing substantially for total volume of railway freight, the disease of railway relevant device is more serious, and especially ten-thousand ton trains increase
Amount is started, to being affected for the associated components such as rail, sleeper in rail system at track switch, for example, track switch song stock gauge becomes
Change very fast, the fast speed that screw spike fractures, nail hole thickening becomes larger, causes sleeper failure aggravation, it is solid that concrete rests the head on track switch iron chair
Determine king-bolt frequently to fracture, the maintenance cycle of rail system at track switch is caused to be obviously shortened.
It is directed to this phenomenon in traditional equipment management, split type tie rod is usually used, i.e., using multiple tie rods and every
The fixed two adjacent rail of a tie rod, make to be mounted in this way the quantity of the rail clip pair for fixing rail on tie rod compared with
It is how (intermediate in this way since centrally located rail needs to connect by the rail of different tie rod two sides adjacent thereto
Need to install on the rail of position two rail clips to), cause occupied space larger, influence big machine tamping quality and ongoing operations,
And more tie rod is arranged at track switch, be easy to cause track circuit connection electricity, while using steel at the track switch of split type tie rod
The intensity of rail system is lower, and the effect for preventing rail traversing is undesirable.In addition, existing tie rod can not prevent rail creeping, lead
Cause rail system safe application performance lower, the upkeep operation period is shorter.
