Nondestructive testing device for steel wire rope

The utility model provides a nondestructive testing device for a steel wire rope, which is applied to the technical field of steel wire rope detection. The shell is provided with a gap allowing the steel wire rope to pass through; the excitation assemblies are arranged on the two sides of the gap; the detection assemblies are arranged on the two sides of the gap; wherein the power supply is electrically connected with the detection assembly, and a controller is electrically connected with the detection assembly; the excitation assembly and the detection assembly are arranged on the two sides of the gap where the steel wire rope penetrates respectively to form the U-shaped sensor array, and compared with a traditional sensor array, the U-shaped sensor array can detect damage of multiple strands of steel wire ropes at the same time and can be conveniently installed on equipment where the steel wire ropes normally operate, the steel wire ropes do not need to be disassembled, and the cost is reduced.
