The invention relates to a one-machine multi-point driving turnout movable point rail frog switching mechanism which is at least provided with two traction points, and each traction point comprises a supporting plate installed at one end of a switch tie in the length direction, a square rod support installed on the supporting plate, a connecting rod assembly installed on the square rod support and a guide rod connected to one end of the connecting rod assembly. The connecting rod assemblies at the adjacent traction points are connected through connecting pipe assemblies; joint iron is mounted on the wing rail corresponding to at least one traction point, and pulling plate assemblies are mounted on the long point rail and the short point rail corresponding to the rest traction points; a square pull rod is mounted on the joint iron; one end of the square pull rod is matched and connected with the power output end of the switch equipment, and the other end of the square pull rod is connected with one end of the guide rod at the corresponding traction point; and the pulling plate assembly is connected with one end of the guide rod at the corresponding traction point. The device is simple and reasonable in structural design, safe and stable in structure, low in manufacturing cost and small in field use and maintenance workload.
本发明涉及一种一机多点驱动道岔可动心轨辙叉的转换机构,其至少具有两个牵引点,每个牵引点包括安装于岔枕长度方向一端的托板、安装于托板上的方杆支撑、安装于方杆支撑上的连杆组件以及连接于连杆组件一端的导杆;相邻牵引点处的连杆组件之间是通过联接管组件连接;在至少其中一个牵引点处对应的翼轨上安装有接头铁,在其余牵引点处对应的长心轨和短心轨上安装有拉板组件;接头铁上安装有方拉杆;方拉杆的一端与转辙设备的动力输出端匹配连接,方拉杆的另一端与其对应牵引点处的导杆的一端连接;拉板组件与其所对应牵引点处的导杆的一端连接。本发明结构设计简单、合理,结构安全稳定、制造成本低、现场使用养护维修量小。
