摘要

PROBLEM TO BE SOLVED: To provide a dismounting device of snow-accretion prevention rings and a dismounting working method of the snow-accretion prevention rings, by which a plurality of the snow-accretion prevention rings mounted on an electric wire at predetermined intervals are easily removed from the electrical wire, and falling of the snow-accretion prevention rings removed from the electrical wire is surely inhibited.;SOLUTION: The dismounting device for the snow-accretion prevention rings is constituted, by a moving housing with a supporting roller for traveling which is movable along the electric wire, an operating rod with a recessed portion, into which a part of the snow-accretion prevention rings is introduced involved in movement of the moving housing, and a chain unit which introduces the other part of the snow-accretion prevention rings between each projected portion of a link chain, directly facing the operating rod, wherein a breakdown force is exerted to the snow-accretion prevention rings by projected portions of the chain unit, using the recessed portion of the operating rod as a support point.;COPYRIGHT: (C)2007,JPO&INPIT
