Large-axle-load turnout fastener
The invention provides a large-axle-load turnout fastener which is used for fixing a steel rail on a concrete switch tie. The large-axle-load turnout fastener is composed of a steel rail lower cushion layer, an iron base plate, an iron base plate lower cushion layer, an iron base, a steel rail gauge block, an iron base plate gauge block, an e-shaped elastic strip and an embedded iron base. The bottom of the embedded iron seat is embedded in the concrete switch tie; the inner side of the top of the embedded iron base is fixed outside the gauge block; the inner sides of the iron backing plate gauge blocks press down and fix the outer sides of the iron backing plates; the outer side of the top of the embedded iron base is provided with a slope. A slope concrete retaining shoulder is arranged on the outer side of the concrete switch tie sinking groove; the slope concrete retaining shoulder and the outer side slope of the top of the embedded iron base are attached, matched and connected into a whole in a pouring mode. According to the invention, the stability of the iron backing plate for resisting transverse impact under the condition of super-large axle load of 40-45 tons is improved; the problems that an embedded iron seat is weak in transverse impact resistance and short in service life under the condition of ultra-large axle load are solved.
提供一种大轴重道岔扣件，用于将钢轨固定在混凝土岔枕上；大轴重道岔扣件由钢轨下垫层、铁垫板、铁垫板下垫层、铁座、钢轨轨距块、铁垫板轨距块、e形弹条、预埋铁座组成；预埋铁座底部埋入混凝土岔枕内；预埋铁座顶部内侧固定铁垫板轨距块外侧；铁垫板轨距块内侧下压固定铁垫板外侧；预埋铁座顶部外侧设有斜面；混凝土岔枕沉槽外侧设有斜坡混凝土挡肩；斜坡混凝土挡肩与预埋铁座顶部外侧斜面贴合适配且浇筑连为一体。本发明提高在40吨～45吨超大轴重条件下铁垫板抵抗横向冲击的稳定性；解决预埋铁座在超大轴重条件下抵抗横向冲击能力弱、使用寿命短的问题。
