Derusting machine for steel rail

The utility model relates to a derusting machine for a steel rail. The derusting machine is characterized by comprising a walking bogie matched with the steel rail (7), so that the derusting machine can move on the steel rail (7), a bench drill (5) is arranged on the walking bogie, a steel wire bowl brush (8) is arranged on a drill head of the bench drill (5), an oil tank (3) is further arranged on the walking bogie, the oil tank (3) is respectively communicated with at least two of oil outlet pipes, and valves (6) are arranged on the oil outlet pipes. The derusting machine has the beneficial effects that (1) the operating personnel can be reduced, and the derusting task can be completed through one motor-trolley driver and two monitoring and mediating personnel; (2) the labor intensity can be alleviated, the manual derusting can be replaced by the mechanical derusting, and the walking can be replaced by the bogie, so that the derusting machine is quick in derusting speed; (3) the oil can be automatically coated, and the oil can be automatically coated after an oil pipe valve is opened; (4) the derusting machine is stable in derusting quality, and obvious in effect due to consistent balance weight; and (5) a mass of worker salary can be saved since the work personnel and the work time can be greatly reduced.
