Embedded stock rail structure for obtuse angle combined frog
The invention belongs to the field of railway turnouts, particularly relates to an inlaid stock rail structure for an obtuse-angle combined frog, and aims to solve the problems that the two ends of an existing inlaid block rail head are lowered, the triangular end is weak, abrasion, block falling and even breakage are prone to occurring, and the requirements for long service life and short maintenance of the obtuse-angle frog cannot be well met. According to the technical scheme, stock rails are arranged in a central symmetry mode, rail head slicing area grooves are formed in one sides of the stock rails, and rail bottom slicing area grooves are formed in one sides of the rail head slicing area grooves. The overall strength and safety of the stock rail can be enhanced, the impact force of wheels can be transmitted to a ballast bed through the base plate, the overall stress of the stock rail is improved, and the wear resistance and the service life of a frog are improved.
本发明属于铁路道岔领域，尤其是一种钝角组合辙叉用镶嵌式基本轨结构，针对现有的镶嵌块轨头两端部存在降低，且成三角形端部比较薄弱，易出现磨损、掉块甚至断裂的情况，无法较好的满足钝角辙叉高寿命少维护要求的问题，现提出如下方案，其基本轨，所述基本轨中心对称设置，所述基本轨的一侧开设有轨头刨切区域槽，所述轨头刨切区域槽的一侧开设有轨底刨切区域槽，本发明中，方案结构及工艺简单，易于加工制造及组装，可以增强基本轨的平顺性，可以增强基本轨整体强度和安全性，还可以同时将车轮冲击力通过垫板传递到道床，改善基本轨整体受力，进而提高辙叉耐磨性和使用寿命。
