Railway vehicle and stone sweeping machine thereof

Abstract

The invention discloses a stone sweeping machine. The stone sweeping machine is characterized in that a support of the stone sweeping machine is fixed onto the front end surface of an axle box, and a stone sweeping structure is fixed to the front side of a wheel set by the aid of the support. The stone sweeping machine can be repositioned, can be fixed onto the axle box and can be guaranteed against being affected by vibration of a primary spring, change of the distance from the stone sweeping machine to a rail surface can be greatly reduced, accordingly, obstacle removing effects can be improved, and high-speed running of a railway vehicle can be effectively guaranteed. The stone sweeping machine has the advantages that the stone sweeping machine is mounted on the axle box and is simple in structure, and good stone sweeping effects can be realized; the support of the stone sweeping machine with the structure is free of weld rib plates, and accordingly weld cracks can be prevented; the distance from a rubber plate to the rail surface can be adjusted via end teeth, and accordingly the stone sweeping machine is safe and reliable. The invention further discloses the railway vehicle with the stone sweeping machine.

Description

technical field [0001] The invention relates to the technical field of urban rail subway, light rail and EMU vehicle structures, in particular to a rail vehicle and a stone sweeper thereof. Background technique [0002] In order to ensure the safe operation of rail vehicles, stone sweepers are generally installed on the car body to remove small obstacles such as gravel or gravel on the track. [0003] At present, the stone sweeper is generally installed on the frame of the bogie. The distance between the stone sweeper and the track is directly affected by the vibration of a series of springs. The distance between the stone sweeper and the rail surface is constantly changing, which affects the obstacle removal effect on the rail surface. The high-speed operation of rail vehicles brings certain safety hazards. [0004] Therefore, in view of the above situation, how to reduce the variation range of the distance between the stone sweeper and the rail surface has become an impor...
