出口泰国BS80A钢轨8号复式交分道岔的设计

Design of BS80A rail 1:8 double slip switches exported to Thailand

道岔用于泰国曼谷既有车场线铁路旧线改造,国内首次设计应用新型AT钢轨爬坡式尖轨代替传统的补强式尖轨。针对电气化改造的需求,道岔轨件、辙叉、垫板形式等均进行了优化设计,满足了用户站场改造需求。

For the BS80 A rail 1∶ 8 double slip switches used in the reconstruction of the existing depot lines in Bangkok Thailand,the new AT rail climbing switch rail is first adopted to replace the traditional reinforcing switch rail. To meet the requirement of electrification,the design of rail parts,crossings and baseplates of the turnout have been optimized to meet the needs of reconstruction of the depot.
