The invention relates to the technical field of traffic and further discloses a point switch external locking mechanism for turnout switching. The locking mechanism comprises a locking rod, a lockinghook, switch rail connecting iron and a locking frame, wherein the locking hook is rotationally connected with a side surface of the switch rail connecting iron, the switch rail connecting iron and the locking frame are fixedly installed on a side surface of a switch rail and a side surface of a stock rail respectively, the locking rod is in sliding connection with the side surface of the lockinghook, and the locking iron is arranged on the side surface of the locking frame. The point switch external locking mechanism for turnout switching is advantaged in that the magnetizing device is arranged at different positions, the direction of current introduced into the electromagnet or the position state of the electromagnet is adjusted in a matching manner, a goal of changing the opposite endmagnetic poles of the magnetized main magnetic block or auxiliary magnetic block is achieved, the repulsive force between the main magnetic block and the auxiliary magnetic block is used for changingthe contact pressure of the locking rod and the lock hook, so stability of the locking rod and the lock hook after locking is improved, the friction force of the locking rod and the lock hook before locking is reduced, and abrasion of a contact surface of the locking rod and the lock hook is reduced.

    本发明涉及交通技术领域,且公开了一种道岔转换用转辙机外锁闭机构,包括锁闭杆、锁钩、尖轨连接铁、锁闭框,所述锁钩转动连接在尖轨连接铁的侧面,所述尖轨连接铁和锁闭框分别固定安装在尖轨和基本轨的侧面,所述锁闭杆和锁钩的侧面滑动连接,所述锁闭框的侧面设置有锁闭铁。该道岔转换用转辙机外锁闭机构,通过将磁化装置安装在不同位置,配合调整通入电磁铁中的电流方向或者电磁铁的位置状态,达到改变磁化后主磁块或者辅磁块相对端磁极的目的,利用主磁块和辅磁块之间的排斥力改变锁闭杆和锁钩接触的压力,从而提高锁闭杆和锁钩在锁闭后的稳固性以及降低锁闭杆和锁钩在锁闭前的摩擦力,减少锁闭杆和锁钩接触面的磨损。
