Wing rail inlaid type alloy steel combined frog and method for replacing quick-wear parts on line through wing rail inlaid type alloy steel combined frog
The invention provides an inlaid wing rail type alloy steel combined frog which comprises a first wing rail, a second wing rail, a point rail, a first insert, a second insert, a first frog heel rail, a second frog heel rail, a spacer iron cluster and an installation system, the first wing rail and the second wing rail are oppositely arranged, and the point rail is arranged between the outlet end of the first wing rail and the outlet end of the second wing rail. The point rail is of a single-side point structure, the first fork heel rail and the second fork heel rail are arranged along the two side lines of the open end of the point rail respectively, the first insert is arranged on the inner side of the first wing rail, and the second insert is arranged on the inner side of the second wing rail. The spacer iron clusters are connected with the inner side face of the first insert and the inner side face of the second insert through bolts in a matched mode. The purpose of prolonging the service life of the frog is achieved by replacing new inserts and point rails on line. The frog heel rail and the wing rail heel end connection spacer iron are kept in a connection state, temperature force can be transmitted easily, the operation temperature range of operation construction is increased, and meanwhile it is guaranteed that the frog meets the welding connection requirement of a seamless track.
本发明提供了一种镶嵌翼轨式合金钢组合辙叉，包括第一翼轨、第二翼轨、心轨、第一镶块、第二镶块、第一叉跟轨、第二叉跟轨、间隔铁集群和安装系统，第一翼轨和第二翼轨相对设置，心轨设置于第一翼轨和第二翼轨出口端之间，心轨为单侧尖端结构，第一叉跟轨和第二叉跟轨分别沿心轨开口端两边线设置，第一镶块设置于第一翼轨内侧，第二镶块设置于第二翼轨内侧，间隔铁集群由若干间隔铁组成，间隔铁集群通过螺栓配合连接第一镶块内侧面和第二镶块内侧面。本发明通过在线更换新的镶块和心轨，实现延长辙叉使用寿命的目的。叉跟轨与翼轨跟端联结间隔铁保持联结状态，有利于传递温度力，增加运行施工的作业温度范围，同时保证辙叉满足无缝线路焊联要求。
