When the sodium hydroxide reacts with the rust, soluble ferrite is produced, thereby removing the rust on the railway track. As the mobile frame 1 continues to move forward, the driving motor 306 drives the bracket A3 through the connecting rod 308 The sliding plate 311 at one end of the sliding groove 305 moves along the sliding groove 305. The sliding plate 311 moves in the sliding groove 305. The multiple sliding plates 311 connected by the transfer rod 312 also move along the sliding groove 305. The sliding plate 311 is supported by the pulley 313 in the sliding groove 305 to move. When the sliding plate 311 moves, it will drive the brush 315 to rub against the surface of the railway track. The bristles on the brush 315 are made of steel wire, which has excellent hardness and wear resistance, and then the dissolved rust on the railway track is removed. When the brush 315 removes the rust, the brush 315 will remove the rust. When rust is present, the water pump A302 in the water tank 301 draws pure water from the water tank 301 and delivers it to the high-pressure nozzle 314 through the connecting pipe A303. The water is pressurized by the water pump A302, and the high-pressure nozzle 314 sprays water, thereby cleaning the sodium hydroxide solution and the reacted ferrite remaining on the surface of the railway track.
