[0002] As an engineering load-bearing device, a steel wire rope is often affected by complex working conditions and environments such as bending fatigue, wear, alternating loads, mechanical impacts, and corrosion during operation. Inevitably, phenomena such as broken wires, wear, deformation, and rust will occur, posing potential safety hazards. Its damage condition and load-bearing capacity are directly related to personnel and production safety. Therefore, it is necessary to use an on-line steel wire rope flaw detector to monitor the damage condition of the steel wire rope.

[0034] The guiding roller 201 is rotatably arranged between the two support seats and is cylindrical;

[0035] Further, as Figure 1 and Figure 2 shown, a cross beam is provided between the two connecting rods, and a spring 3 is provided on the cross beam. The spring 3 is connected to the handle 5, and the up and down movement of the guiding roller 201 can be realized through this spring 3 to contact the steel wire rope.

[0036] When the on-line steel wire rope flaw detector provided by the embodiment of the present utility model is in use, the upper main body 101 and the lower main body 102 are opened, the steel wire rope to be detected is clamped between the upper main body 101 and the lower main body 102, then the upper main body 101 is closed, and the lock catch 103 is locked.
