Novel alloy steel point rail combined obtuse frog
The invention discloses a novel alloy steel point rail combined obtuse frog which comprises a stock rail, a guard rail, an alloy steel point rail and a frog heel rail, a platen is arranged at the bottom of the guard rail, the stock rail and the guard rail are both formed by machining 60TY1 steel rails, and the widened side of a rail head faces the alloy steel point rail. The widths of the rail head are gradually reduced to the width of a common 60kg/m steel rail head from the symmetrical middle shaft of the stock rail to the bending points at the two sides, the widths of the rail head are kept unchanged as thecommon 60kg/m steel rail head from the bending points of the stock rail to the tail end of the stock rail, and the thickness of a rail web is kept consistent with that of the rail web of the 60kg/m steel rail within the range of at least 450mm from the tail end of the stock rail; the width from the symmetrical middle shaft of the guard rail to the rail heads of the bending points at the two sides is gradually reduced to the width of the rail head of a common 60 kg/m steel rail, an opening section with the rail head width gradually reduced is arranged at the tail section of the guard rail, and the height of the rail head is kept unchanged within the harmful space range of the guard rail. A transition section is arranged at the tail end of the harmful space of the guard rail to reduce the height of the rail head to offset the thickness of the platen and keep the rail head to the tail end of the guard rail.
本发明公开了一种新型合金钢心轨组合钝角辙叉，包括基本轨、护轨、合金钢心轨以及叉跟轨，在护轨底部设有台板，基本轨和护轨均采用60TY1钢轨加工而成且轨头加宽一侧朝向合金钢心轨，从基本轨对称中轴分别至两侧弯折点轨头宽度逐渐减小至普通60kg/m钢轨轨头宽度，从基本轨弯折点至末端保持轨头宽度为普通60kg/m钢轨轨头宽度不变，从所述基本轨末端至少450mm范围内轨腰保持与60kg/m钢轨轨腰厚度一致；从所述护轨对称中轴分别至两侧弯折点轨头宽度逐渐减小至普通60kg/m钢轨轨头宽度，在护轨末段设置轨头宽度逐渐减小的开口段，护轨有害空间范围内轨头高度保持不变，从护轨有害空间末端设置过渡段使轨头高度降低至抵消台板厚度并保持该轨头高度至护轨末端。
