Self-adaptive structure frog
The invention provides a self-adaptive structure frog which comprises a point rail and a wing rail, the point rail is a point rail tip in a wheel-rail transition area, the other end of the point rail is a point rail heel end, the point rail heel end is fixedly connected with a line steel rail, the wing rail is a wing rail tip in a wheel-rail transition area, the other end of the wing rail is a wing rail toe end, and the wing rail toe end is fixedly connected with the line steel rail. The invention relates to the technical field of railway transportation equipment manufacturing, when train wheels pass through a frog wheel-rail transition area, the rail surfaces of the point rail and the wing rail or wing rail inserts are adjustable, and when the bearing pressure reaches a certain value, certain automatic adjustment is generated, so that the rail surfaces of the point rail and the wing rail or the wing rail inserts can be automatically adjusted, and the train wheels are prevented from being damaged. On one hand, the probability that the point rail surface and the wing rail surface jointly bear train wheels is increased, and the independent bearing probability is reduced; and on the other hand, the acting time of impact force between the wheels and the rails is prolonged, the acting force is reduced, the service life of the point rail and the wing rail or the wing rail insert is prolonged, and the service life of the whole frog is correspondingly prolonged.
本申请提供了一种自适应结构辙叉，包括心轨以及翼轨，心轨在轮轨过渡区为心轨尖端，另一端为心轨跟端，心轨跟端和线路钢轨连接固定，翼轨在轮轨过渡区为翼轨尖端，另一端为翼轨趾端，翼轨趾端和线路钢轨连接固定，心轨尖端和翼轨尖端的下端设有自适应结构，涉及铁路运输设备制造技术领域，当火车车轮经过辙叉轮轨过渡区时，心轨和翼轨或翼轨镶块的轨面是可调的，当承载压力到达一定值时，会产生一定的自动调整，一方面使得心轨面和翼轨面共同承载火车轮的概率增加，减少了单独承载概率；另一方面，延长了车轮和轨道之间冲击力的作用时间，减低了作用力的大小，使得心轨和翼轨或翼轨镶块的使用寿命增加，整组辙叉寿命也相应增加。
