摘要
分析、比较了固定辙叉、长翼轨可动心轨和短翼轨可动心轨 3种辙叉型式、限位器及间隔铁 2种辙跟型式的无缝道岔纵向力传递机理及其对无缝道岔各部件受力和变形的影响 .研究表明 ,辙叉采用长翼轨可动心轨。
The regularity of longitudinal force transmission of welded turnouts with differ ent types of frog and heel is investigated, and the effects of frogs and heels o n the force and displacement of the parts of a welded turnout are discussed. The types of frog and heel dicussed include rigid frog, long-wing movable-point f rog and short-wing movable-point frog for the former and spacer block and spac ing restricting device for the latter. The research result shows that combinatio n of the long-wing movable-point frog and the spacing restricting device is a more reasonable structure of welded turnouts.
