A NOVEL REFERENCE LINE SCRIBING DEVICE AND METHOD FOR RAIL INSTALLATION

The present invention relates to the technical field of a scribing device, more specifically, to a novel reference line scribing device and method for rail installation. A novel reference line scribing device for rail installation, comprising a mounting plate fixed on a large disk of a beveling machine, wherein a waist groove penetrates through the outer wall of the mounting plate, and a pipe body penetrates through the waist groove; the outer wall of the pipe body is threadedly connected with fixing pieces; the fixing pieces are distributed on the two sides of the mounting plate; a movable block is slidably connected in the pipe body, and an elastic piece is arranged on the movable block, and an alloy scribing cutter head for scribing the surface of the steel pipeline is arranged below the movable block. In the use of a novel reference line scribing device for rail installation patented by the present invention, start the rotation of the large disk of the beveling machine, so that a circular reference line parallel to the end face of the bevel can be scribed on the surface of the steel pipeline with the alloy scribing cutter head. Because the propulsion on the alloy scribing cutter head from the first spring is relatively stable, the consistency of the depth of the reference line can be ensured, so that the scribing is clear and not discontinuous, showing a good result.
