The invention provides a guide rail flexible driving device and a turnout. The guide rail is provided with at least two driving point positions in the linear length direction of the guide rail. Each driving point is provided with a rotary cam mechanism; the rotating cam mechanisms are connected through connecting rods and connected with the output end of the crankshaft through the connecting rods. The crankshaft input end is connected with the electric push rod; one electric push rod drives all the rotating cam mechanisms to execute actions; linear structures are arranged at the two ends of a cam groove body of the rotary cam mechanism and used for locking after the guide rail is driven in place. And the displacement stroke of the guide rail driven by each rotary cam mechanism is consistent with the lift of the cam groove at the point position. The method is high in reliability; the guide rail is high in flexible deformation linear precision and rigidity, and vehicles can pass stably and comfortably; simplified design of the turnout beam structure is facilitated; the cost and the failure rate are low; the device is not only suitable for suspension type movable core turnouts, but also can be applied and popularized on other turnouts.
提供一种导向轨挠性驱动装置及道岔,包括导向轨;导向轨沿其线形长度方向设有至少两个驱动点位;每个驱动点位具有旋转凸轮机构;旋转凸轮机构之间通过连杆连接并通过连杆连接曲柄轴输出端;曲柄轴输入端连接电动推杆;一台电动推杆驱动所有旋转凸轮机构执行动作;旋转凸轮机构具有的凸轮槽槽体两端均制有直线结构,直线结构用于导向轨驱动到位后的锁止;每个旋转凸轮机构驱动导向轨位移的行程与该点位凸轮槽的升程一致。本发明可靠性高;导向轨挠性变形线型精度高,刚度大,车辆通过稳定、舒适;有利道岔梁结构简单化设计;成本低,故障率低;不仅适用于悬挂式可动芯道岔,还可在其它道岔上应用推广。
