The invention discloses a frog casting which comprises a frog center rail and is characterized in that a pair of side rails are symmetrically arranged on the two sides of the frog center rail, the pair of side rails are the first side rail and the second side rail respectively, each side rail comprises a first blocking rail, the first blocking rails are parallel to one side of the frog center rail, and one end of each first blocking rail is connected with a second blocking rail; a movable blocking rail is arranged at the other end of the first blocking rail and arranged between the first blocking rail and the running rail. The movable blocking rail is arranged at the other end of the first blocking rail, and the movable blocking rail is arranged between the first blocking rail and the running rail, so that the movable blocking rail can move to fill a harmful interval existing on a traditional rail, and a train can safely pass through during rail transfer; the technical problem that in the existing frog design, a harmful space exists between a wing rail and a frog center, and the space may cause derailment danger during rail transfer of a train is solved.

    本发明公开了一种辙叉铸件,包括叉心轨道,其特征在于:叉心轨道两侧对称设有一对侧轨,一对侧轨分别为第一侧轨和第二侧轨,侧轨包括第一挡轨,第一挡轨与叉心轨道一侧平行,第一挡轨一端连接第二挡轨,第一挡轨另外一端设有可移动档轨,可移动挡轨设在第一挡轨和跑轨之间。本发明通过第一挡轨另外一端设有可移动档轨,可移动挡轨设在第一挡轨和跑轨之间,从而使得可移动挡轨可以移动填补传统轨道上存在的有害区间,从而使得火车在变轨是可以安全通过,解决了目前辙叉设计上存在翼轨和辙叉心之间存在有害空间,该空间可能会使火车在变轨是出现脱轨危险的技术难题。
