The invention discloses a cam power-off device for a point switch and the point switch. The left end and the right end of an operating rod (5) of the device are mounted in mounting holes of a left supporting plate (1) and a right supporting plate (2) respectively; a baffle plate (4) is mounted at one end, extending out of the left supporting plate (1), of the operating rod (5); a displacement contactor (8) is mounted on the outer side of the right supporting plate (2); a cylindrical surface contact cam (3) is mounted at one end, extending out of the right supporting plate (2), of the operating rod (5); the operating rod (5) rotates to drive the shielding plate (4) to rotate to shield or expose the motor output shaft (100); meanwhile, the cylindrical surface contact cam (3) is driven to rotate to jack up or release the contact (81); the switch machine is controlled to be powered on and powered off through the shifting contactor (8). The switch machine recovery process is easy to operate, and single-person operation is facilitated; an independent recovery interface is provided, and the safety risk of electric shock does not exist; the structure is simple, all functional parts are located on the same rotating shaft, and the system reliability is high.

    本发明公开了一种转辙机用凸轮断电装置与转辙机,装置的所述的操纵杆(5)左右两端别安装于左支撑板(1)与右支撑板(2)的安装孔中;所述的操纵杆(5)伸出左支撑板(1)的一端安装遮挡板(4);右支撑板(2)外侧安装移位接触器(8);所述的操纵杆(5)伸出右支撑板(2)的一端安装柱面接触凸轮(3);操纵杆(5)旋转带动遮挡板(4)转动遮挡或露出电机输出轴(100);同时,带动柱面接触凸轮(3)转动,顶起或放开触头(81);通过移位接触器(8)控制转辙机通断电。恢复转辙机过程操作简单,利于单人操作;具备独立的恢复接口,不存在触电的安全风险;结构简单,所有功能件处于同一转动轴上,系统可靠性高。
