Description

Technical Field

[0001] The utility model relates to the technical field of non-destructive testing, in particular to a non-destructive testing device for a drum wire rope. Background Art

[0002] The drum wire rope is in a long-term working state, working in a harsh working environment, and is subject to wear and tear during long-term work. In order to ensure the safe operation of the drum, the operator must regularly visually inspect the wire rope to observe whether there are broken wires or rust. Since the drum wire rope is long, one person is required to operate the drum and one person to perform visual inspection during visual inspection. The wire rope moves slowly, which leads to low inspection efficiency. In addition, the operator's long-term observation of the wire rope is prone to errors, posing a safety hazard. In order to solve the problems of manual visual inspection, some online detection devices have emerged in the prior art. For example, the patent with announcement number CN216387039U discloses an online detection device for prestressed steel cylinder concrete pipe wrapped with prestressed steel wire.

[0003] However, drum wire ropes are wound around a drum, as shown in patents CN216272843U and CN217996630U. Because drum wire ropes swing parallel to the drum axis during retraction and retraction, existing detection devices are not suitable for detecting drum wire ropes. Utility Model Content
