The invention belongs to the technical field of rail transit, and provides a turnout coupler lock device applied to urban rail transit and an implementation method thereof.The turnout coupler lock device comprises a screw rod, a fixed hook arranged at the front end of the screw rod, a movable hook assembly arranged on the screw rod and a fastening nut assembly which is connected to the screw rod in a sleeving mode and is in threaded connection with the screw rod; the screw rod is sleeved with the connecting sleeve, the connecting sleeve is located between the fastening nut assembly and the movable hook assembly, external threads are arranged on part of the outer wall of the upper end of the connecting sleeve, the other part of the connecting sleeve is an external smooth section, internal threads matched with the threads of the screw rod are arranged on part of the inner wall of the upper end of the connecting sleeve, and the other part of the connecting sleeve is an internal smooth section. The fastening performance of the movable hook relative to the screw rod is improved, and the technical problem that in the prior art, fastening is achieved only through a single plum nut, and thread slipping is likely to happen after long-term use is solved through the design of a multi-thread connection structure.
本发明属于轨道交通技术领域,提供了一种应用于城市轨道交通的道岔钩锁器及其实现方法,其中,道岔钩锁器包括螺杆,设置在螺杆前端的固定钩,设置在螺杆上的活动钩组件,套接在螺杆上并与螺杆螺纹连接的紧固螺母组件,以及套接在螺杆上并位于紧固螺母组件和活动钩组件之间的连接套筒,连接套筒上端的部分外壁设置有外螺纹、另一部分为外光滑段,连接套筒上端的部分内壁设置有与螺杆的螺纹匹配的内螺纹、另一部分为内光滑段。本发明不仅提高了活动钩相对螺杆的紧固性,而且多重螺纹连接结构的设计,避免了现有技术仅采用单一梅花螺母实现紧固,长期使用下易发生滑丝的技术问题。
