The invention relates to the technical field of railway vehicles, in particular to a locking device for automatic butt joint and separation of wind power of a railway vehicle, which comprises an air cylinder and a locking pin which are respectively arranged on two sides of two mechanical butt joint bodies which are in butt joint with each other, a piston is installed in the air cylinder and divides the air cylinder into a front cavity and a rear cavity, and a piston rod is installed on the piston, the piston rod penetrates through a cylinder body of the air cylinder from the front cavity, therod head of the piston rod is movably provided with a locking hook so that the locking hook can rotate clockwise or anticlockwise on the vertical plane in the linear advancing direction of a train, asliding table making contact with the inclined face of the locking hook is installed on one side of the mechanical butt joint body provided with the air cylinder, and a spring is installed in the rearcavity of the air cylinder, and an exhaust hole is arranged, the air inlet hole is formed in the front cavity of the locking air cylinder, pressure air enters the front cavity from the air inlet hole, the piston rod retracts, the locking hook retracts, meanwhile, the needle is instantly hung on the locking pin in a rotating mode, locking work of the two butt joint devices is achieved, and separation caused by external force is avoided.
本发明涉及铁路车辆技术领域,尤其涉及一种用于铁路车辆风电自动对接及分离的锁紧装置,包括分别安装在两个相互对接的机械对接体两侧的风缸和锁紧销,风缸内安装有活塞,活塞将风缸分为前后腔室,活塞上安装有活塞杆,活塞杆从前腔室贯穿风缸的缸体,活塞杆杆头活动安装有锁紧勾,使得锁紧勾能够在列车直线行进方向的竖直平面上做顺时针或逆时针旋转,安装有风缸的机械对接体一侧安装有与锁紧勾倾斜面接触的滑台,并在风缸后腔室安装有弹簧,且设置有排气孔,并在锁紧风缸前腔室设置有进气孔,压力空气从进气孔中进入前腔室,活塞杆回缩,锁紧勾回缩的同时瞬时针旋转挂在锁紧销上,实现了两个对接装置的锁紧工作,避免外力导致其分离。
