重载可动心轨道岔的研究

Study on Heavy duty Movable point Frog Turnout

研究了一种重载可动心轨道岔， 其独特的可动心轨、长翼轨及接头铁的设计使可动心轨辙叉关键部件工作应力大幅度降低， 道岔整体性能和使用寿命得到提高。

We have devoted to the study of a heavy duty type movable point frog turnout.The unique design of the movable point frog,the long wing rail and the joint block can reduce the working stress of the pivotal part of movable point frog by a large margin inteqrated performance and working life of the frog are also improved.
