ワイヤロープ検査装置、ワイヤロープ検査システム、およびワイヤロープ検査方法
Document Type and Number:
Japanese Patent JP7443960
Kind Code:
B2
Abstract:
To provide a wire rope inspection device capable of easily inspecting damage.SOLUTION: A control unit 21 of a wire rope inspection device 100 performs addition control which matches starting points of a first signal string as a detection signal based on a plurality of detection parts W10 detected by a differential coil 10 (detection part) during movement of a wire rope W in one direction while passing through the differential coil 10 and a second signal string that a portion other than the detection signal by a leading length L (predetermined length) of the first signal string is extracted from the first signal string, to make an addition. Therefore, the control unit 21 is configured to detect the state of the wire rope W by overlapping detection signals corresponding to a partial detection part W10 out of the plurality of detection parts W10 to make an addition.SELECTED DRAWING: Figure 1
