摘要： PROBLEM TO BE SOLVED: To efficiently remove the welding residue on a lower face of a rail joint. SOLUTION: A base 6 moved along the longitudinal direction of a rail R by the rotation of a first screw rod 9 is loaded on a machine easing 1 fixed to the rail R to each other by a clamping device 4. A moving base 11 moved in the direction perpendicular to the rail R by the rotation of a second screw rod 13 is loaded on the base 6. A cutter 16 provided with a grinding blade 16A formed by a cemented carbide tip for grinding a welding residue Ra' of the lower face of the rail joint is mounted on the moving base 11 in such manner that its height is adjustable.

摘要： PROBLEM TO BE SOLVED: To provide a cutting device applicable to a plurality of kinds of track rails and preventing the scattering of dust. SOLUTION: A movable carriage 5 moving along the longitudinal direction of the track rail R to be cut is mounted on a machine body 1 to which the track rail R is attached. A bearer 15 is supported to the movable carriage 5 through a height adjusting device, and a plurality of cutting devices selectively movable forward and backward in the direction of a web Ra of the track rail R are mounted on the bearer 15. Each cutting device is provided with cutters 20A, 20B of different shape from each other, fitted to the web Ra of the track rail R and rotated by driving motors 28A, 28B.

摘要： PROBLEM TO BE SOLVED: To prevent erroneous test results from occurring in examining a rail due to the presence of level difference practically causing no trouble. SOLUTION: This grinding device is equipped with a device base frame 1 in the bottom side of the rail R and mounts a moving body 5 moving in the direction crossing with the rail R in the device base frame 1. The moving body 5 is equipped with a grinding body 11 turning diagonally to the bottom surface of the rail R and a grinding blade 12 is projected to the top end of the grinding body 11.

摘要： PROBLEM TO BE SOLVED: To surely cut and correct only a place to be cut and corrected, without grinding an unnecessary place, by selecting an upper surface or a side surface of a rail head part.
SOLUTION: This cutting-correcting device is composed of a pair of device base boards 1A and 1A detachably fixed to the rail head part Ra by a clamping device 2, and opposed via a joint welding residual part RA, a horizontally moving frame 3 interposed between the pair of device base boards, moving in the direction along the peripheral side of the rail head part, and stationed in a prescribed position by a positioning means, a moving stage 13 installed in the horizontally moving frame so as to be freely movable in parallel in the longitudinal direction of the rail head part, and a cutter body 17 for making the joint welding residual part by operating on the moving stage by a driving motor 16.
