FIG. 1 is a schematic side view showing an embodiment of a mobile cutting device according to the present invention. FIG. 2 is a schematic front view of FIG. 1. FIG. 3 is a schematic view showing a feed mechanism portion of the disc cutter, and FIG. 4 is an explanatory view showing an embodiment of drive means in the moving carriage. First, as shown in FIGS. 1, 2 and 3, a rotary screw type feed mechanism 11 was attached to a fixed base 10 and an operation handle 12 was provided. And
The movable mount 20 was configured so that the mount on which the electric disk cutter 13 was mounted was mounted on the fixed mount 10 via the LM guide 19 so as to be slidable. That is, the movable base 20 equipped with the electric disk cutter 13 is configured to be freely movable in the front-back direction with respect to the material to be cut.

に保持する役目を持つ。In the lower part of the fixed base 10, as means for moving in the left-right direction with respect to the material to be cut, that is, in the lateral direction,
Four guide rollers 21 are attached vertically to the electric disc cutter 13 via left and right shafts 22, and guide rollers 23 are attached to the front, rear, left and right under the fixed mount 10 via a cylindrical case equipped with a compression coil spring. The base was attached to form a roller mechanism. The H-shaped steel 24 as a guide rail for movement installed in parallel with the material to be cut (steel sheet pile or the like) is engaged and moved. That is, the guide rollers 21 are set on both flanges of the H-section steel 24, and the angle members 25 (square steel or square pipe may be provided) provided on both outer side surfaces of the flange.
The guide roller 23 was set on the guide and moved. The compression coil spring described above has a role of optimally maintaining the sliding state between the angle member 25 and the guide roller 23.
