Frog
The invention discloses a frog which comprises a wing rail A, a wing rail B, a point rail C and a point rail D. The wing rail A is provided with a tread A for wheels to walk, the wing rail B and the point rail D are provided with continuous treads for the wheels to walk continuously, and the tread A and the continuous treads are provided with a transition section A and a transition section B for the wheels to run on the continuous treads and the tread A at the same time respectively. The height difference between the transition section A and the transition section B is the height difference between the wheel rim and the wheel tread; one side of the point rail C is provided with a wheel flange groove for a wheel flange to walk; the wheel flange groove is obliquely arranged, the highest point of the wheel flange groove is connected with the continuous tread, and the height of the wheel flange groove is basically consistent with that of the transition section B; the rail top treads of the wing rail B and the point rail D in the frog are continuous and uninterrupted, so that harmful space is effectively eliminated, wheels can be smoothly transited to the point rail C from the wing rail A through rim transition and arrangement of the supporting faces of the rim grooves, and then the frog can be matched with steel rails of different models.
本发明公开了一种辙叉，包括翼轨A、翼轨B、心轨C和心轨D,所述的翼轨A具有供车轮行走的踏面A，所述的翼轨B和心轨D具有连续不间断的供车轮行走的连续踏面，所述的踏面A和连续踏面分别具有车轮同时运行在连续踏面和踏面A上的过渡段A和过渡段B，所述的过渡段A与过渡段B的高度差为车轮轮缘与车轮踏面的高度差；在所述的心轨C一侧设置有供轮缘行走的轮缘槽所述的轮缘槽倾斜设置且最高点与连续踏面衔接且高度与过渡段B基本保持一致；该辙叉中翼轨B与心轨D的轨顶踏面连续不间断，从而有效消除有害空间，且通过轮缘过渡以及轮缘槽的支撑面斜面设置能够实现车轮从翼轨A平顺过渡到心轨C上，进而使得该辙叉能够匹配不同型号的钢轨。
