The invention belongs to the technical field of rail transit, and particularly relates to a locking device, a turnout and a rail transit system. The locking device comprises a locking assembly, a check block and an elastic piece, the locking assembly abuts against the elastic piece, the locking assembly is provided with a first locking groove, a second locking groove and a turnout locking groove, the first locking groove communicates with the second locking groove, and the turnout locking groove is used for allowing a lock pin of a turnout to enter or disengage in the first direction; therefore, the turnout can be locked or unlocked. According to the turnout locking device, the locking pin can be clamped in the turnout locking groove by clamping the locking shaft and the second locking groove and locking the locking assembly, and rapid locking of the turnout is achieved. When unlocking is needed, the locking shaft is separated from the second locking groove, locking of the locking assembly is relieved, rapid unlocking of the turnout is achieved, the turnout can be rapidly locked and unlocked, the switching time of the turnout is shortened, and the switching speed of the turnout is increased.

    本发明属于轨道交通技术领域,特别是涉及一种锁闭装置、道岔及轨道交通系统。锁闭装置包括锁定组件、挡块和弹性件,所述锁定组件抵接所述弹性件,所述锁定组件具有第一锁止槽、第二锁止槽和道岔锁定槽,所述第一锁止槽连通所述第二锁止槽,所述道岔锁定槽用于供道岔的锁销沿第一方向上进入或脱出,以对道岔进行锁定或解锁。本发明中,通过锁定轴与第二锁止槽进行卡接,锁止锁定组件,即能将锁销卡接在道岔锁定槽中,实现道岔的快速锁止。需要解锁时,锁定轴脱离第二锁止槽,解除锁定组件的锁止,实现道岔的快速解锁,使得道岔能够快速锁闭和解锁,从而缩短了道岔的转辙时间,提升了道岔的转辙速率。
