る。[Detailed description of the invention] (a) Industrial application field The present invention is a polishing device that uses a grinding wheel to polish the surface of a laid railway rail, in which the pressure of the grinding wheel on the rail surface is kept constant. This invention relates to a pressing device.

２Km程度で使用できず交換するが無理な押圧によ
る研磨では更に耐久性に欠ける。(c) Problems that the invention aims to solve In conventional polishing equipment, an eccentric wheel or a hydraulic cylinder is used to press the grinding wheel against the rail surface, and polishing is performed by always pressing the grinding wheel toward the rail surface. It's on. Therefore, when the wave-like irregularities generated on the rail surface are small, the grinding wheel is pressed against the rail surface by the pressing means, and the concave and convex surfaces are polished while remaining as they are. As a result, flat polishing cannot be expected, and trains running at high speed on rails vibrate violently, so even thorough polishing was not very effective. In addition, when polishing the rail surface, the grinding wheel is usually 1.5~
It cannot be used after about 2km and is replaced, but if it is polished with excessive pressure, it will become even less durable.

A spiral cam ring designed according to the amount of the load is received, and the rotation of the spiral cam ring from the wheel running on the rail is reduced by a reducer and rotated through a chain, and the rotation of the spiral cam ring generates a grindstone. The wheel is lowered according to the amount of wear and the rail surface is polished with a constant pressure, and the convex parts of the uneven waveforms that occur on the rail surface are polished to make them flat. The pressing force is blocked by the spiral cam wheel, and the grinding wheel is gradually lowered by the rotation of the spiral cam wheel, and the grinding wheel is always pressed against the rail surface with a constant pressure to perform polishing.
