Cowcatcher, device and bogie

Abstract

The invention discloses a cowcatcher, a device and a bogie, and belongs to the technical field of railway vehicle body parts, the cowcatcher is provided with a cowcatcher body part capable of being arranged on one side of a running rail, and the upper portion of the cowcatcher body part is provided with a mounting structure used for fixing the position of the cowcatcher body part. The lower portion of the cowcatcher body part is provided with a cowcatcher part which is used for being close to the rail face of a running rail and can protrude towards the central axis of the center in the running direction of a vehicle, and the two ends of the cowcatcher part are fixedly connected with the cowcatcher body part through a welding technology. The cowcatcher of the invention has a novel structure, the welding operation space and the observation space are increased, so that the welding manufacturability is improved, the structural reliability is high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of rail vehicle body parts, in particular to an obstacle remover, a device and a bogie. Background technique [0002] During the running of subway vehicles, any obstacle on the track may damage the train, or even cause the train to derail, causing serious safety accidents. In the vehicle, the obstacle remover adopts a welded structure of steel pipe and steel plate, which has problems such as poor welding process, resulting in poor welding quality and prone to welding defects. Moreover, there is random vibration between the wheel and rail, and its vibration frequency is usually the same as that of the steel pipe. The type welding structure is close, which greatly affects the service life of the obstacle remover, and the reliability is poor; [0003] Therefore, with regard to the above problems, those skilled in the art urgently need to provide an obstacle remover, device and bogie.
