Abstract

The invention discloses an anti-overturning device used for a railway vehicle, an operation method thereof and a railway vehicle bogie. The device comprises a displacement sensor, a control device and an anti-overturning hook plate, wherein the displacement sensor is used for detecting the stress state of an axle box spring of the railway vehicle, and the control device and the anti-overturning hook plate are connected with the displacement sensor. A hook part capable of hooking the lower surface of a railhead of a railway is arranged at the first end of the anti-overturning hook plate, the second end of the anti-overturning hook plate is installed on the bogie of the railway vehicle in a rotatable mode, and the control device is used for pushing the hook part of the anti-overturning hook plate to hook the lower surface of the railhead of the railway or leave the railway according to information collected by the displacement sensor. The operation method includes the step that the control device controls the anti-overturning hook plate to act. Two anti-overturning devices are installed below the two sides of the bogie respectively, and displacement sensors are installed between a wheel pair of the railway vehicle and a frame of the bogie. Vertical separation between the wheel pair and the railway can be effectively prevented, and the anti-overturning stability of a train can be substantially improved.

Description

technical field [0001] The invention relates to the field of rail transportation equipment, in particular to an anti-overturning device for a rail vehicle, an operation method thereof, and a rail vehicle bogie. Background technique [0002] With the gradual increase of train speed, the possibility of train overturning is getting higher and higher. Especially when a high-speed passenger train running along the track passes through a curve, if the speed of the train is not accurately controlled, the centrifugal force when turning is too large, and the train may overturn. In addition, in a strong wind environment, especially in a bad wind environment, trains running at high speed along the track or trains parked on the track will be impacted by strong lateral wind, and the risk of train overturning will greatly increase. In addition, if the train is impacted by bumping into an obstacle during operation, the head of the train will rise upwards, the bogie will go up and leave th...
