<p><P>PROBLEM TO BE SOLVED: To provide a dismounting device of slow snow-accretion rings and a dismounting working method of the slow snow-accretion rings, by which a plurality of the slow snow-accretion rings mounted on an electric cable at predetermined intervals are easily removed from the electrical cable, and falling of the slow snow-accretion rings removed from the electrical cable is surely inhibited. <P>SOLUTION: The dismounting device for the slow snow-accretion rings P is constituted by an operating rod 2 and a cutting house 3, wherein the operating rod 2 includes a recessed portion 4 so that it is inserted and fix a part of the slow snow-accretion rings P mounted on the electrical cable S; and the cutting housing moves in parallel, along the electrical cable S directly facing the recessed portion 4, and has a convex portion 5 which exerts breakdown force to the slow snow-accretion rings P, using the recessed portion 4 of the operating rod 2 as a support point. Moreover, in the dismounting working method of the slow snow-accretion rings, a body 1 of the dismounting device of the slow snow-accretion rings P, comprising the operating rod 2 and the cutting housing 3, is fitted to the electric cable S; the body 1 of the dismounting device is moved along the electric cable S; the operating rod 2 is fixed to the electric cable S, in such a state that the slow snow-accretion rings P are in a state of being inserted into the recessed portion 4 of the operating rod 2; and then the cutting housing 3 is moved, to rupture the slow snow-accretion rings P by the convex portion 5 of the cutting housing 3. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
