Split type combined frog
The invention discloses a split type combined frog which comprises a point rail and a pair of wing rails, the point rail is connected with a pair of frog heel rails, a bridge type base plate is arranged in the area from the theoretical tip end of the point rail to the 50-100 section, the inner side of each wing rail is provided with an embedded block, the point rail, the wing rails and the embedded blocks are connected through bolt pairs, and the point rail and the frog heel rails are connected through bolt pairs, the point rail and the embedded block are made of forged high manganese steel or alloy steel materials, the two ends of the embedded block are hidden in the wing rail to form a tip hiding structure, the point rail comprises a working section and a connecting section which are wedge-shaped, and the side edge of the bottom of the connecting section is wrapped by the fork heel rail. The connecting section is in close fit with the rail top bottom and the rail bottom top of the fork heel rail through inclined planes; v-shaped first slopes are arranged on the two sides of the rail web of the working section, a second slope is arranged at the top of the rail bottom of the working section, the spacer iron is matched with the embedded block through a spigot structure, and the embedded block is in close fit with the rail top bottom and the rail bottom top of the wing rail through slopes.
本发明公开了一种分体式组合辙叉，包括心轨和一对翼轨，在心轨上连接有一对叉跟轨，在心轨理论尖端至50～100断面区域内设置桥式垫板，在各翼轨内侧均设有镶嵌块，心轨、翼轨和镶嵌块通过螺栓副连接，心轨和叉跟轨通过螺栓副连接，设有防转钢垫圈和间隔铁，心轨和镶嵌块选用锻造高锰钢或合金钢材料制成，镶嵌块两端均藏于翼轨内呈藏尖结构，心轨包括工作段和连接段且均呈楔形，连接段底部侧边被叉跟轨包裹，连接段与叉跟轨的轨顶底部以及轨底顶部通过斜面贴紧配合；工作段轨腰处两侧设置呈V型的第一斜面，工作段轨底顶部设置第二斜面，间隔铁与镶嵌块通过止口结构配合，镶嵌块与翼轨的轨顶底部以及轨底顶部通过斜面贴紧配合。
