  The present invention relates to a rail correction device that corrects unevenness on a rail surface with a grindstone piece, a rail correction method, and a rail grinding wheel that smoothly corrects unevenness on a rail surface.

FIG. 13 is a conceptual diagram schematically showing the grinding operation of a conventional rail grinding device, FIG. 13 (A) is a perspective view showing the rotating state of the grinding wheel, and FIG. 13 (B) is the movement of the grinding stone. FIG. 13 (C) is a plan view showing the state of the rail after grinding, FIG. 13 (D) is a cross-sectional view showing the state of the rail after creation, and FIG. E) is a graph showing a change in the unevenness of the rail before and after the cutting by the conventional rail cutting apparatus. Here, the vertical axis shown in FIG. 13E is the uneven distribution (mm ² / mm ⁻¹ ), and the horizontal axis is the spatial frequency (1 / mm).

  One of the loud sound sources of railway noise is rolling noise radiated by vibration of wheels and rails when a railway vehicle travels. The cause of rolling noise is thought to be due to the roughness of the rail top surface and the wheel tread surface, and the noise can be reduced by rail grinding work that removes the roughness of the rail top surface that contacts the wheel tread surface. Are known. As shown in FIG. 13, the conventional rail grinding apparatus 105 includes a disk-shaped rotary grindstone 106 that is in rotational contact with the surface of the rail R. In such a conventional rail grinding apparatus 105, as shown in FIGS. 13A and 13B, while rotating the rotating grindstone 106 in a horizontal plane, the rotating grindstone 106 is moved in the direction of the arrow in the figure, thereby moving the rail R The surface is ground. In the conventional rail shaving apparatus 105, when undulating irregularities on the surface of the rail R are observed after grinding, the rotating grindstone 106 rotates once (for example, A of the rotating grindstone 106, as shown in FIGS. 13B to 13D). The distance a (generally about 2 to 3 cm) traveled by the rotating grindstone 106 during one round of the portion is taken as one mountain, and innumerable streaks in the direction perpendicular to the rail R (the sleeper length direction) The remaining correction marks remain. As a result, for example, as shown in FIG. 13 (E), at a frequency other than the specific frequency corresponding to the distance a, the unevenness distribution is reduced after the reduction and the rolling noise is lower than before the reduction. However, at the specific frequency corresponding to the distance a, the uneven distribution increases conversely and the rolling noise also increases. For this reason, in the conventional rail shaving apparatus 105, although it aims at extending | stretching the life of the rail R and reducing rolling noise by grinding the surface of the rail R, FIG. 13 (C) (D) Unlike the original purpose, the situation where the rolling noise increases due to the cutting traces caused by the wavy irregularities as shown in FIG. For this reason, a rail correction apparatus for solving such problems has been proposed.

  A conventional rail grinding apparatus includes a first roller and a second roller that are spaced apart from each other in the length direction of the rail, and a pulley that is disposed above an intermediate position between the first and second rollers. A belt-like endless abrasive web member that is wound around the first and second rollers and pulleys to polish the top surface of the rail, and the endless abrasive web between the first and second rollers. A biasing shoe that presses against the surface, a motor that rotationally drives the pulley so that the endless abrasive web material moves along the length of the rail, and a first roller and the pulley that are disposed between them. A first tension roller that prevents the endless abrasive web from sagging, a second tension roller that is disposed between the second roller and the pulley and prevents the endless abrasive web from sagging therebetween, and the like. (For example, refer to Patent Document 1)Such a conventional rail shaving device smoothes unevenness such as wavy wear generated on the top surface of the rail by smoothing the endless polishing web, thereby preventing noise caused by the top and bottom surface of the rail. At the same time, the deterioration of the rail is suppressed.

  In the conventional rail grinding apparatus, in order to prevent the endless polishing web from slacking when the endless polishing web is driven at a high speed, the first and second tension rollers are disposed, and the first and second tension rollers are arranged. A biasing shoe is disposed between the rollers. For this reason, in the conventional rail shaving apparatus, there are problems that the number of parts for preventing the endless polishing web from slackening increases, the structure of the entire apparatus becomes complicated, and the apparatus becomes expensive. Further, in the conventional rail shaving apparatus, when the endless abrasive web is worn, it is necessary to remove the worn endless abrasive web from the first and second rollers, pulleys, etc. and replace it with a new endless abrasive web. There is a problem that the replacement work takes time.

Next, when the control device 24 controls the driving force generation unit 10 of the driving device 7 and the driving force generation unit 10 rotationally drives the driving shaft 8a of the rotating body 8A, the rotating bodies 8A to 8D shown in FIG. The winding member 9 is rotated to move, and the grindstone piece 6 continuously moves in the length direction of the rail R in a state where it is in contact with the top surface R ₁ .

When the correction of the top surface R ₁ is completed, the controller 24 controls the operation of the fluid pressure circuits 15c and 16c, and the fluid pressure is maintained until the grindstone piece 6 contacts the gauge corner portion R ₃ shown in FIG. The circuits 15c and 16c supply or discharge the working fluid to the cylinder portions 15a and 16a. Then, when the driving force generating unit 10 a control device 24 shown in FIG. 4 is an operation control, the rotating body 8A~8D is moved winding member 9 rotates, the grindstone pieces in contact with the gauge corner portion R ₃ 6 moves continuously in the length direction of the rail R.

When the grinding of the gauge corner portion R ₃ is completed, the control device 24 controls the operation of the fluid pressure circuits 15c and 16c, and the fluid is maintained until the grindstone piece 6 comes into contact with the inner head side surface R ₂ shown in FIG.
