By means of the opening and closing means mounted on the main body, the respective supporting rollers are supported and are in contact with the rail and separated from the rail.

Specifically, the chamfering member is made of a sanding member, more specifically, the chamfering member is made of a cutting chip.

In the rail chamfering apparatus of the present invention, since the reference roller and the support roller press the side surfaces of the rail, the main body can move while being supported on the rail, and the main body can be moved by the rotation of the drive wheel by the drive motor. The body can move alone on the rail. In this state, since the bottom flange formed in the lower portion of the support roller is in contact with the lower surface of the corner portion of the rail, the support roller is not in contact with the rail and does not move upward. Unlike the related art, it is not connected to the crane and can move alone. The upper corner portion of the rail is chamfered by sanding or cutting of the rotating chamfering member.

In the chamfer mentioned above, sanding or cutting can be selected by using a sanding member or a cutting chip as the chamfering member.

Preferred embodiments of the rail chamfering apparatus according to the present invention will now be described in detail with reference to the drawings.
