<p>PROBLEM TO BE SOLVED: To obtain a sheave passage-type anchor clamp device which surely prevents a drop in the mechanical strength due to the repeated bending deformation, of an electric wire, applied at a time when a sheave is passed by a method wherein a cylindrical mouth protective device which is composed of an elastic body and of a rigid body is installed at the tip mouth on the electric-wire insertion side of a clamp body. SOLUTION: A sheave passage-type anchor clamp body 2 is composed of a steel clamp 21 and of an aluminum clamp 22, and a protective device 3 on one side is composed of an elastic body 31 and of a rigid body 32. The elastic body 31 is formed in such a way that a split is formed in an elastic material such as rubber or the like and that an overhead transmission line 1 is inserted so as to be covered. Then, a taper part 31a, for insertion and attachment, in an end part is inserted into, and attached to, the tip mouth part of the clamp 22. The rigid body 32 is formed to be a cylindrical shape by steel or the like, inward ring-shaped protrusions 32a are formed at both ends, they are split into two parts, the rigid body covers the tip mouth part of the clamp 22 and the elastic body 31 so as to be crossed over, and the inward ring-shaped protrusions 32a are fitted externally and coupled to the tip mouth part of the clamp 22 and to the outer circumferential groove of the elastic body 31. At this time, the external fitting and coupling operation of the elastic body 31 and the rigid body 32 set by a binding wire 1 and the aluminum clamp 22 is maintained.</p> |
