60AT1做长心轨的固定型合金钢辙叉设计

Design of fixed alloy steel crossing with long point rail made of 60AT1 rail

主要介绍了60AT1合金钢钢轨做长心轨的60 kg/m钢轨12号固定型合金钢组合辙叉的结构特点,并针对辙叉结构进行了检算分析。辙叉满足线路使用要求,且结构简单,各种零部件易于加工,制造安装方便,生产周期短。

This paper mainly introduces the structural characteristics of the No.12 fixed alloy steel crossing of 60 kg/m rail with long point rail made of 60AT1 rail,and makes the relevant calculation and analysis for the crossing structure.The crossing meets the requirements of railway line use,and has simple structure,convenient processing and manufacturing of parts,and short production cycle.
