The sanding unit module adopts a sanding belt as a sanding tool, takes the motor as a power source, adopts the rechargeable lithium battery to supply power to the motor, the motor drives the sanding belt wheel train to sand during the operation of the sander, the stepping motor controls the sanding belt wheel train to longitudinally feed, and the transverse position and the sanding angle of the sanding belt wheel train are adjusted by the transverse moving hand wheel and the swinging hand wheel. When the steel rail grinding machine is used for grinding, the contact wheel rubber layer and the abrasive belt are in flexible contact with the steel rail due to the characteristics of the contact wheel rubber layer and the abrasive belt, so that the influence of the vibration of the grinding machine on the surface layer of the steel rail is reduced, and the grinding quality is improved. The rail modularized abrasive belt grinding wagon is pushed by the driving module to move along the rail, so that automatic control can be realized, the labor consumption is reduced, and the consistency of grinding quality is enhanced.
