The invention relates to the technical field of rail transit vehicles, in particular to a coupler opening device, a coupler and a railway vehicle. The hook opening device comprises an air storage cylinder, an air cylinder, a transmission mechanism and a control mechanism. After air in the air storage cylinder enters the cylinder body through the first air valve, the piston can be pushed to move in the first direction, so that the piston drives the coupler knuckle to rotate in the direction away from the coupler head through the transmission mechanism, and the coupler is opened. Under the condition that opening of the car coupler is completed, the control mechanism can control air in the air storage cylinder to enter the cylinder body through the second air valve so as to push the piston to move in the cylinder body in the direction opposite to the first direction, and transmission connection between the transmission mechanism and the coupler knuckle is disconnected. The coupler opening device is used for opening the coupler of the railway vehicle, automatic coupler opening of the coupler can be achieved through the coupler opening device, an operator does not need to manually rotate the coupler knuckle, and therefore the marshalling efficiency is improved, the working intensity is reduced, and the personal safety of the operator is guaranteed.

    本发明涉及轨道交通车辆技术领域,尤其涉及一种开钩装置、车钩和铁路车辆。本申请提供的开钩装置,包括储风缸、气缸、传动机构和控制机构。其中,储风缸中的空气通过第一气门进入缸体后能够推动活塞沿第一方向运动,使得活塞通过传动机构带动钩舌向远离钩头的方向转动,以使车钩开钩;在车钩开钩完成的条件下,控制机构能够控制储风缸中的空气通过第二气门进入缸体中,以推动活塞在缸体中沿第一方向的反方向运动,且使传动机构与钩舌断开传动连接。本申请提供的开钩装置,用于对铁路车辆的车钩进行开钩,通过该开钩装置,可实现车钩的自动开钩,而无需作业人员手动转动钩舌,从而提高了编组效率、降低了工作强度,保证了作业人员的人身安全。
