Alloy steel embedded combined frog for channel rail
The invention relates to a rail technology, in particular to an alloy steel embedded combined frog for a channel rail. The alloy steel embedded combined frog comprises groove-shaped wing rails arranged on the two sides and a point rail located between the wing rails; and also comprises alloy steel wing rails, two of the alloy steel wing rails are embedded into the middles of the groove-shaped wingrails, arranged on the two sides of the front portion of the point rail respectively and extend forwards to cross the throat of a frog, and two groove-shaped fork heel rails are arranged on the two sides of the rear end of the point rail respectively; the groove-shaped wing rails, the alloy steel wing rails, the point rail and the fork heel rails are each provided with a plurality of transverse through holes used for being connected into a whole through bolt connecting pairs. The alloy steel embedded combined frog is reasonable in design and convenient to machine. The toe end and the heel endof the frog are both made of groove-shaped rails, and line connection is facilitated.
本发明是关于轨道技术，特别涉及一种槽型轨合金钢嵌入式组合辙叉。包括设于两侧的槽型翼轨和位于翼轨之间的心轨；还包括合金钢翼轨，合金钢翼轨有两根嵌入槽型翼轨中部，分设于心轨的前部两侧且向前延伸并越过辙叉咽喉位置，心轨后端两侧分设有两根槽型叉跟轨；槽型翼轨、合金钢翼轨、心轨和叉跟轨上均设有若干横向通孔，用于通过螺栓连接副连接为一体。本发明设计合理，加工方便。辙叉趾端、跟端均为槽型轨制造，便于线路连接。
