本発明は、鉄道線路のレール頭部に摩耗が生じた場合に
、そのレール形状を補修し修正する方法および装置に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a method and apparatus for repairing and correcting the rail shape of a railway track when the rail head is worn out.
［従来の技術１
鉄道線路のレール頭部表面（上面や側面）には、レール
上を走行する車両の車輪との間の摩擦笠により、レール
長さ方向に波状に凹凸を呈する摩耗や変形等が発生ずる

ｉ音公害をもたらすことになる。そのためレール頭部の
表面に摩耗等が生じたときには、その摩耗状態等に応じ
てレールの頭部形状を修正することが行なわれている。[Conventional technology 1] The surface of the rail head (upper surface and side surface) of a railway track is subject to wear and deformation that exhibits wavy irregularities in the length direction of the rail due to friction between the wheels of vehicles running on the rail. occurs. As such rail wear progresses, vibrations and shocks generated when vehicles pass are severe, leading to damage to the track and roadbed, and σr;7
This will lead to sound pollution. Therefore, when wear or the like occurs on the surface of the rail head, the shape of the rail head is corrected depending on the wear condition.
従来、レール形状を修正する方法としＣは、レール頭部
表面に生じた摩耗等による凹凸の特に画部分を、モータ
により回転駆動される砥石をもっで削り取って凹凸を消
去する、つまり削正（研削により修正する）手段による
方法が一般的である（例えば特開昭６０−９５００３号
、特開昭６０−１１９８０１号）。Conventionally, method C for correcting the rail shape is to use a grindstone driven by a motor to remove the unevenness caused by wear etc. on the surface of the rail head, especially the image area, to erase the unevenness. A common method is to repair by grinding (for example, JP-A-60-95003, JP-A-60-119801).
［発明が解決しようとりる問題点］
しかし、レール頭部の波状に凹凸を呈する摩耗等はその
凹凸の高低差が０．４〜０．５ｍにまで及ぶことがあり
、その場合、上記従来のように削正手段のみによる修正
方法では、摩耗による凹凸を完全に削り取ることが難し

といった問題らある。[Problems to be Solved by the Invention] However, when the rail head is worn and has unevenness in a wavy manner, the difference in height between the unevenness may reach 0.4 to 0.5m. As mentioned above, it is difficult to completely remove the unevenness caused by wear with the correction method using only grinding means, and moreover, the time required for one sharpening with a grindstone is usually only about 0.05 seconds, so it is difficult to completely remove the unevenness caused by wear. The larger the difference, the more the number of cuts will need to be made, and the longer the correction work will take. Further, if the correction using only the lower stage of cutting is repeated, there is a problem that the outline of the rail head shape gradually becomes smaller.
本発明は、上記に鑑みて、摩耗が激しく凹凸の高低差が
かなり大きい場合でも、削正回数をごく少なくしてかつ
レール頭部の輪郭を小さくすることなく、所定のレール
形状に容易にして正確に修正できる、能率的なレール形
状の修正方法と装置を提供しようとするものである。In view of the above, the present invention makes it possible to easily form a rail into a predetermined shape by minimizing the number of times of grinding and without reducing the profile of the rail head, even when the wear is severe and the difference in height between the concavity and convexity is quite large. It is an object of the present invention to provide an efficient method and device for correcting rail shapes that can be corrected accurately.

るように所定形状に削正するものである。That is, the rail shape IILE method of the present invention first measures the amount of wear on the rail head to be corrected, and then thermally sprays metal on the rail head depending on the measured wear condition to repair the head surface. The shape is made to some extent by the sprayed coating layer. In other words, the depth of the recesses on the head surface is increased by spraying m to make the sprayed coating layer thicker than the convex parts, or metal spraying is applied only to the recesses. Make the head surface almost flat over the entire length. Thereafter, the surface of the rail head on which the sprayed coating layer has been formed is ground into a predetermined shape so as to correspond to the standard contour of the rail.

A repair device, a grinding device that grinds the rail head that has been ground into a predetermined shape, and a measuring device that measures the shape of the ground rail head are attached to a work vehicle that can run on the rail. It is characterized by being equipped with

強度を保有する。[Function 1] According to the method of the present invention described above, metal is sprayed on at least four parts of the rail head depending on the wear condition of the rail head to be corrected, and the head surface is coated with a sprayed coating layer. After repairing the shape to a certain extent, it is possible to make the rail shape approximately uniform over the entire length of the rail correction section, and with a very small amount of machining, it is possible to grind the rail into a predetermined rail shape that corresponds to the standard contour, and the number of times of grinding can be increased. Moreover, since the overlay area formed by the thermal sprayed coating layer is ground down, the outline of the head shape does not become smaller. However, the metal melt can be built up in a very thin layer, and there is no excessive buildup, no steps are created, and subsequent grinding can be carried out without any inconvenience. Even if the thermally sprayed coating layer is extremely thin, it will reliably and firmly weld and integrate with the rail, and has sufficient strength.

る。Furthermore, according to the above-mentioned device of the present invention, while the work vehicle is running, it is possible to measure the amount of wear on the rail head, repair it by metal spraying according to the wear state, grind the rail head, and measure the shape after grinding. It can be carried out continuously and efficiently, and combined with the fact that there is little need to cut back, the rail head can be corrected without repeating the work section many times and retreading.
