The invention belongs to the technical field of railway traffic, and discloses a railway turnout external locking device which comprises a locking cylinder, a locking sleeve, a first locking block, a second locking block and a locking rod, the locking cylinder is connected to a stock rail, the locking sleeve is connected to a switch rail, the locking sleeve is movably installed in the locking cylinder in a penetrating mode, and the locking rod is installed in the locking sleeve in a penetrating mode. The locking sleeve has a first limit position and a second limit position when driving the switch rail to move, namely a close attaching position and a repulsion position corresponding to the switch rail. The locking rod can drive the locking sleeve to move between two limit positions through the first locking block or the second locking block, when the locking sleeve moves to the first limit position, the first locking block can be clamped in the first limiting groove, and when the locking sleeve moves to the second limit position, the first locking block can be clamped in the second limiting groove. The locking sleeve can be locked and fixed at the two extreme positions, namely, the switch rail connected with the locking sleeve can be locked and fixed at the close attaching position and the repulsion position, the stability when a vehicle passes through the turnout is guaranteed, and potential safety hazards are reduced.

    本发明属于铁路交通技术领域,公开一种铁路道岔外锁闭装置,包括锁闭筒、锁闭套、第一锁闭块、第二锁闭块以及锁闭杆,锁闭筒连接于基本轨,锁闭套连接于尖轨,锁闭套活动穿装于锁闭筒内,锁闭杆穿装于锁闭套内,锁闭套带动尖轨移动时具有第一极限位置和第二极限位置,即对应于尖轨的密贴位置和斥离位置。锁闭杆能够通过第一锁闭块或第二锁闭块带动锁闭套在两个极限位置之间移动,锁闭套移至第一极限位置时,第一锁闭块能够卡设于第一限位槽,锁闭套移至第二极限位置时,第一锁闭块能够卡设于第二限位槽,锁闭套在两个极限位置均能够锁止固定,即与之相连的尖轨在密贴位置和斥离位置均能够被锁止固定,保证道岔过车时的稳固性,降低安全隐患。
