Frog structure
The invention provides a frog structure, and belongs to the field of rail transit. The frog structure comprises a first arc main rail, a second arc main rail, a first point rail, a second point rail,a first wing rail and a second wing rail. The second arc main rail and the first arc main rail are bent towards the same side. The second point rail is connected with the first point rail to form an elastically bendable point rail assembly, and the tip of the point rail assembly is provided with a first position and a second position. The first wing rail and the second wing rail are located on theouter sides of the first point rail and the second point rail respectively. When the tip is located at the first position, the tip abuts against the second wing rail, and the second wing rail and thefirst point rail form a first arc auxiliary rail concentric with the first arc main rail. When the tip is located at the second position, the tip abuts against the first wing rail, and the second point rail and the first wing rail form a second arc auxiliary rail concentric with the second arc main rail. According to the frog structure, a movable frog technology is adopted, so harmful space of the frog is effectively eliminated, running safety of a train is guaranteed, and the frog structure can better adapt to curve terrains.
本申请提供了一种辙叉结构，属于轨道交通领域。辙叉结构包括第一圆弧主轨、第二圆弧主轨、第一心轨、第二心轨、第一翼轨和第二翼轨。第二圆弧主轨与第一圆弧主轨向同侧弯曲。第二心轨与第一心轨连接并形成弹性可弯的心轨组件，心轨组件的尖部具有第一位置和第二位置。第一翼轨和第二翼轨分别位于第一心轨和第二心轨的外侧。当尖部位于第一位置时，尖部抵靠于第二翼轨，第二翼轨与第一心轨形成与第一圆弧主轨同心的第一圆弧副轨。当尖部位于第二位置时，尖部抵靠于第一翼轨，第二心轨与第一翼轨形成与第二圆弧主轨同心的第二圆弧副轨。该辙叉结构采用可动心辙叉技术，有效消除了辙叉的有害空间，保证列车的行驶安全，且能够更好的适应曲线地形。
