略一定にする押圧装置に関する。[Detailed Description of the Invention] (a) Industrial Application Field The present invention provides a polishing device for polishing the surface of a laid railway rail using a grinding wheel, in which the pressure of the grinding wheel against the rail surface is controlled by a magnet. This invention relates to a pressing device that maintains a substantially constant pressure by repulsion.

研磨も余り効果がなかつた。(c) Problems to be solved by the invention In conventional polishing devices, a hydraulic cylinder is mainly used to press the grinding wheel against the rail surface, and the hydraulic cylinder directly presses the grinding wheel toward the rail surface to perform polishing. I'm going. Therefore, when the wave-like unevenness generated on the rail surface is small, the grinding wheel is pressed against the rail surface by the cylinder of the grinding wheel, and the concave and convex surfaces are polished while remaining as they are. Therefore, flat polishing cannot be expected. As a result, trains traveling at high speed on the rails vibrated violently, and even extensive polishing was not very effective.

It softens the surface of the rail and presses it evenly, polishing the uneven corrugated protrusions that occur on the rail surface into a flat surface.

Then, the upper magnet 22 provided on the connecting piece 20 descends together with the connecting piece 20, but if the position of the lower magnet 26 facing the upper magnet 22 is set in advance,
The repulsion between the magnets 22 and 26 causes the grinding wheel 11 to
The descending of the cylinder 19 is regulated regardless of the pressure applied to the cylinder 19, and grinding is performed at a set pressure. Further, by adjusting the lower magnet 26, polishing can be performed with appropriate pressure.

1 toward the rail 2, but the pressing force of this pressing cylinder 19 is regulated by the repulsive force between the upper magnet 22 provided on the connecting piece 20 and the lower magnet 26 opposed to this, and the pressing force of the grindstone is By adjusting the lower magnet 26 to the appropriate position, polishing can be performed at a substantially constant pressure. Therefore, even when there are small waves, only the convex portions of the corrugated irregularities that occur on the surface of the rail 2 are polished, so that they can be polished flat. That is, there is no need to polish the concave and convex portions along the concavities and convexities as in the conventional method.
