Number 9 single turnout for subway tunnel
A ninth single turnout for a subway tunnel comprises a straight stock rail, a curved stock rail, a curved switch rail, a linear switch rail, a curved guide rail, a linear guide rail, a guard rail and a curved frog. The curve frog comprises a point rail, a linear frog heel rail, a curve frog heel rail, a linear wing rail and a curve wing rail, and working edges on the two sides of the point rail are a curve working edge and a linear working edge respectively. The working edge of the curve switch rail, the working edge of the curve guide rail, the working edge of the curve wing rail, the curve working edge of the point rail and the working edge of the curve fork heel rail are located on the same guide curve, the curve switch rail, the curve guide rail and the curve wing rail are sequentially in butt joint, and the linear switch rail, the linear guide rail and the linear wing rail are sequentially in butt joint. The radius of a guide curve of an existing ninth single turnout is increased to 280-300 m, and the whole frog part is invaded, so that the lateral permissible passing speed of the ninth single turnout is increased to 45 km/h.
一种地铁隧道用9号单开道岔，包括直基本轨、曲基本轨、曲线尖轨、直线尖轨、曲线导轨、直线导轨、护轨及曲线辙叉；所述曲线辙叉包括心轨、直线叉跟轨和曲线叉跟轨、直线翼轨及曲线翼轨，且所述心轨的两侧工作边分别为曲线工作边和直线工作边；所述曲线尖轨的工作边、曲线导轨的工作边、曲线翼轨的工作边、心轨的曲线工作边及曲线叉跟轨的工作边位于同一条导曲线上，且所述曲线尖轨、曲线导轨、曲线翼轨依次对接，所述直线尖轨、直线导轨、直线翼轨依次对接。本发明通过将现有9号单开道岔的导曲线半径增大至280‑300m并侵入整个辙叉部分，使其侧向允许通过速度提高至45km/h。
