The invention provides a reverse guard rail for a high-speed railway. The reverse guard rail comprises a wheel guard, a wheel guard arm, a C-shaped wheel guard rail, a wheel guard rail seat and a connecting plate, a wheel protection arm flange is connected to the outer side of a bottom beam of a high-speed rail wheel bogie, the wheel guard arm is arranged on the wheel protection arm flange, and the protection gard is installed at the outer end of the wheel protection arm. The C-shaped wheel guard rail covers the guard wheel and limits the guard wheel, and the guard rail seat is arranged at thelower part of the C-shaped guard rail and is fixed on a ballast bed through an anchor bolt; the connecting plate is arranged between the C-shaped guard rails, and the guard rails are locked through bolts. The upper portion of the C-shaped guard rail is of an arc structure and corresponds to the outer circle outline of the guard wheel of the cage cover, and a limiting gap is kept. The wheel guardis installed in the outer side of the bottom beam of the high-speed rail wheel bogie, the C-shaped protective wheel rail of the arc-shaped structure covers the wheel guard, and the wheel guard freelypasses through the C-shaped protective wheel rail without contact and friction; when an accident occurs, the high-speed rail wheel is hooked by the C-shaped guard rail, and a derailment accident is avoided. The reverse guard rail is suitable for high-speed railways.

    本发明提出的是一种高速铁路反向护轮轨。包括护轮、护轮臂、C型护轮轨、护轮轨座和连接板;在高铁车轮转向架底梁外侧,连接有护轮臂法兰,护轮臂法兰上设有护轮臂,护轮臂外端安装有护轮;C型护轮轨将护轮罩住并对其进行限位,C型护轮轨下部设有护轮轨座,并通过锚固螺栓固定在道床上;C型护轮轨之间设置有连接板,螺栓将护轮轨锁紧。C型护轮轨上部为圆弧结构,与笼罩的护轮外圆轮廓相应并保持限位间隙。本发明采用在高铁车轮转向架底梁外侧安装护轮,具有弧形结构的C型护轮轨将护轮罩住,护轮在C型护轮轨内自由通过,没有接触和摩擦;在出现意外时,高铁车轮被C型护轮轨勾住,避免脱轨事故。适宜作为高速铁路反向护轮轨应用。
