High manganese steel movable core frog structure
The invention discloses a high manganese steel movable point frog structure which comprises a left side wing rail, a right side wing rail, a left side frog heel switch rail, a right side frog heel switch rail, a high manganese steel point rail, a pivot assembly and a traction device. The pivot assembly comprises a pivot and an iron base plate; the pivot is matched with a pivot hole in the iron base plate; the groove in the heel end of the high manganese steel point rail is connected with the pivot in a matched mode. Compared with an existing movable core structure, the structure is small in longitudinal occupied space, the harmful space in the frog is eliminated, and the unevenness of transition between the wing rails and the point rail is reduced; the point rail rotates rigidly around the pivot, traction force is small, and pulling is more flexible. The heel end of the point rail is in inclined attachment transition with the fork heel switch rail, so that the point rail is convenient to replace; the characteristics of high ductility and high impact toughness of high manganese steel are fully utilized, the service life of the frog is prolonged, and the frog can be used for heavy-load lines.
本发明公开了一种高锰钢可动心辙叉结构，该结构包括左侧翼轨、右侧翼轨、左侧叉跟尖轨、右侧叉跟尖轨、高锰钢心轨、枢轴组件以及牵引装置；所述枢轴组件包括枢轴以及铁垫板；所述枢轴与所述铁垫板上的枢轴孔配合；所述高锰钢心轨跟端的凹槽与所述枢轴相互配合连接。该结构较现有可动心结构纵向占用空间小，消除了辙叉内的有害空间，减小了翼轨与心轨之间过渡的高低不平顺性；心轨绕枢轴进行刚性旋转，牵引力小，扳动更加灵活。心轨跟端与叉跟尖轨斜贴过渡，便于心轨更换；充分利用高锰钢材质高延伸率和高冲击韧性的特性，提高辙叉的使用寿命，可用于重载线路。
