摘要： PROBLEM TO BE SOLVED: To eliminate position where inspection is impossible just before or after the obstacle by running over an obstacle such as a wire connection sleeve. SOLUTION: In this wire inspection device 1, a running distance from a base point is measured by a rotary encoder 30, while it runs on a wire W by means of rollers 12, 13 for detecting a damaged condition of the wire W by damage detectors 21, 22 provided with eddy current sensors. For a sleeve S as an obstacle on the wire W, its back end is detected by a sensor 31, and its forward end is detected by a sensor 32. First, the damage detector 21 is placed on an inspection position, with the damage detector 22 placed on a retraction position, so the wire W is inspected by the damage detector 21 only while it runs. As the back end of the sleeve S is detected by the sensor 31, the damage detector 21 is retracted upward at a position close to the back end. After passing the sleeve S to detect the forward end by the sensor 32, the front and the back damage detectors 21, 22 are both restored, and inspection is restarted. The damage detector 22 starts inspection at a position close to the forward end of the sleeve S. After running for a specified distance, the damage detector 22 is retracted upward, and inspection is performed by the damage detector 21 only.
