Fixed alloy steel combination railway frog

The utility model provides a fixed alloy steel combination railway frog, include heart rail and the wing rail that is located heart rail both sides, the main part of wing rail is ordinary rail, the easy abrasion part of wing rail is alloy steel portion, the alloy steel portion of wing rail with heart rail is a solid forging spare, has connecting portion between the wing rail alloy steel portion ofthis solid forging spare and the heart rail. Because heart rail forms as a solid forging with the alloy steel portion of installing on the wing rail, just so reduce the wearing and tearing that haveleaded to with having eliminated traditional combination railway frog to have the joint gap to and because potential safety hazard that the fatigue fracture of connecting piece arouses makes the security of railway frog and stability very improve. 本实用新型提供了种固定型合金钢组合辙叉，包括心轨和位于心轨两侧的翼轨，所述翼轨的主体为普通钢轨，所述翼轨易磨损部位为合金钢部，所述翼轨的合金钢部和所述心轨是个整体锻造件，该整体锻造件的翼轨合金钢部和心轨之间具有连接部。由于心轨和安装于翼轨上的合金钢部是作为个整体锻造而成，这样就减少和消除了传统组合辙叉存在连接间隙而导致的磨损，以及由于连接件的疲劳断裂引起
