Fixed high manganese steel combined frog
A fixed high-manganese steel combined frog comprises a high-manganese steel frog core, two wing rails and two frog heel rails, the two wing rails are symmetrically fixed to the two sides of the high-manganese steel frog core, and the two frog heel rails are symmetrically fixed to the two sides of the tail of the high-manganese steel frog core and located between the two wing rails; the matching position of the front end of the high-manganese steel fork core and the wing rail starts from the throat of the frog, and the tread surface of the front end of the high-manganese steel fork core is gradually lowered towards the throat of the frog, so that the tread surface of the front end of the high-manganese steel fork core at the throat of the frog is lower than the tread surface of the wing rail; and therefore, the wheels are not in contact with the treads of the high manganese steel fork core at the throat of the frog, but are in complete contact with the treads of the wing rails. The wheel-rail relation at the frog throat is innovatively designed, the overall length of the frog center can be effectively shortened, the weight of the frog center is reduced, and the manufacturing cost is saved.
一种固定型高锰钢组合辙叉，包括高锰钢叉心、两根翼轨及两根叉跟轨，所述两根翼轨对称固定在高锰钢叉心的两侧，两根叉跟轨对称固定在高锰钢叉心尾部的两侧，且位于两根翼轨之间；所述高锰钢叉心前端与所述翼轨的配合位置始于辙叉咽喉处，且高锰钢叉心前端的踏面向辙叉咽喉处逐渐降低，使高锰钢叉心前端在辙叉咽喉处的踏面低于翼轨的踏面，进而使车轮在辙叉咽喉处不与高锰钢叉心的踏面接触而是与翼轨的踏面完全接触。本发明通过对辙叉咽喉处轮轨关系进行创新设计，可有效缩短叉心整体长度，减轻叉心重量，节约造价。
