我矿革命职工,在抓大事、促大干,大搞矿山机械化和技术革新的群众运动中,创制成功一种电磁式自动道岔。这种道岔主要由活动岔尖、拉杆、弹簧、电磁铁、附加架线及连接导线等六种构件组成(见图1)。电磁铁和弹簧的一端分别固定在道岔两边,拉杆设在道轨下面,其两端分别与电磁铁的可动铁芯螺孔和弹簧的 I am a revolutionary mine workers, grasping major events, and promote large-scale, large-scale mining mechanization and technological innovation in the mass movement, the successful creation of an electromagnetic automatic turnout. This kind of turnout is mainly composed of six kinds of components such as moving fork, pull rod, spring, electromagnet, additional wire and connecting wire (see Figure 1). One end of the electromagnet and the spring are respectively fixed on both sides of the turnout, the pull rod is arranged under the track rail, the two ends of the electromagnet and the spring are respectively connected with the movable iron core screw hole of the electromagnet and the spring
