Combined frog and lateral reinforced railway turnout
The invention relates to a railway turnout, in particular to a combined frog and a lateral reinforced railway turnout, the combined frog comprises a wing rail I, a wing rail II and an alloy steel point rail, the part of the wing rail I, which is positioned at the crossed position of the wing rail I and the wing rail II, is provided with an arc-shaped convex part far away from the wing rail II; an alloy steel embedded block is arranged between the arc-shaped protruding part and the alloy steel point rail, and the arc-shaped protruding part, the alloy steel point rail, the alloy steel embedded block and the second wing rail are connected. According to the combined frog, the lateral structural strength of the frog is improved, the risks of impact, cracks, breakage and the like on the first wing rail caused by the fact that the lateral frog crossing speed of a train is too high are avoided, the alloy steel embedded block is installed on one side of the first wing rail in a matched mode, and due to the excellent mechanical properties of high strength, high abrasion resistance, impact resistance and the like of alloy steel materials, the service life of the combined frog is prolonged. And therefore, the impact of train wheels can be effectively resisted, and the train passing safety of the combined frog is ensured after the lateral passing speed of the turnout is increased.
本发明涉及一种铁路道岔，特别是一种组合辙叉及侧向加强型铁路道岔，组合辙叉包括：翼轨一、翼轨二和合金钢心轨，翼轨一位于所述翼轨一和翼轨二的交叉位置的部分设置有远离所述翼轨二的弧形凸出部，所述弧形凸出部与所述合金钢心轨之间设置有合金钢镶嵌块，所述弧形凸出部、所述合金钢心轨、合金钢镶嵌块和所述翼轨二相连接。本申请所述的一种组合辙叉，提高了辙叉侧向结构强度，避免因列车侧向过岔速度过高造成的对翼轨一的冲击、裂纹、断裂等风险，翼轨一一侧配套安装合金钢镶嵌块，因合金钢材料的高强度、高耐磨及耐冲击等优良的力学性能，进而能够有效抵抗列车车轮的冲击，以保证道岔侧向通过速度提高后，组合辙叉的过车安全。
