<p><P>PROBLEM TO BE SOLVED: To provide an electric wire inspection device that can inspect by attaching a relatively heavy weight inspection apparatus simply and safely to a wire in a hot-line state. <P>SOLUTION: The electric wire inspection device 1 comprises an insulating guide rod 3 and a lift 4. The insulating guide rod 3 hangs an attachment part 2 to the overhead electric wire W and makes it droop. The lift 4 moves on the insulating guide rod 3 by itself. The inspection apparatus 17, a control part 18 and a drive power supply 19 are mounted to the lift 4. The insulating guide rod 3 is erected, the attachment part 2 is hung to the electric wire W, the lift 4 is rased, the inspection apparatus 17 is brought close to the electric wire W, and then an inspection is performed. A frame 8 of the lift 4 surrounds the insulating guide rod 3 and is openable and closable. A plurality of wheels 9 are supported to the frame 8. Two frame members 10, 11 of the frame 8 are hinged to each other at their one-side ends and clamped by clamping members 13 at the other ends so as to be releasable. The wheels 9 are press-contacted to the external periphery of the insulating guide rod 3 in a state that the frame members 10, 11 are clamped, thus making the lift 4 move up and down by a friction force. <P>COPYRIGHT: (C)2004,JPO</p> |
