IPC: G01N27/83
Filed: 1991-01-25
Abstract: PURPOSE:To enhance the efficiency of flaw detection work by continuously changing the relative position of a wire rope, a magnetizing device and a magnetic sensor and detecting the leaked magnetic flux caused by a flaw in the residual magnetic flux of the magnetized wire rope by the magnetic sensor. CONSTITUTION:An exciting current is allowed to flow to the exciting coil 12 of a magnetizing device 10 while a wire rope 9 is allowed to run at a constant speed by rotationally driving rollers 16a, 16b to successively magnetize the respective parts of the wire rope 9. Since the wire rope 9 has high coercive force, when the rope is once magnetized to form magnetic flux, the magnetic flux remains even when the magnetized position of the rope is shifted from the position of the magnetizing device. Especially, when a flaw or disconnection is present in the wire at the magnetized part of the rope, magnetic flux collectively remains in the flaw or disconnection part as compared with a normal part. The leaked magnetic flux caused by the residual magnetic flux of the flaw or disconnection part is detected and measured by the magnetic sensor.
