Sweeping device for railway track

The invention relates to the technical field of railway tracks, and discloses a sweeping device for a railway track. The sweeping device comprises a shell I, a motor, a rotating shaft, a notch and a driving wheel, wherein a cover plate is fixedly connected to the interior of the shell I, a sleeve I is fixedly connected to the exterior of the cover plate, and a sleeve rod I is movably connected tothe interior of the sleeve I in a sleeving mode; through the interaction of a pressing wheel, a push plate, a push rod, the sleeve rod I, the sleeve I, a spring I, a sleeve III and a rack, pressing wheels on the two sides can be clamped on the two sides of the track; meanwhile, when the pressing wheels encounter slag, the push rod can be driven to push a bevel gear I through stretching and retracting of the spring I, and the bevel gear I is enabled to be separated from a bevel gear II, so that power is not provided for the driving wheel any more, the rotating speed of the driving wheel is gradually reduced, the situat
