Design of On-line Nondestructive Inspection System of Steel Rope of Mine Hoist and Its Applicatio

The paper introduced weak magnetism inspecting principle of steel rope and expounded construction and working principle of an on-line nondestructive inspection system of steel rope of mine hoist. The application showed that the system can inspect inner and outer broken wire and destruction of steel rope of mine hoist with high efficiency, which saves cost of steel rope effectively and reduces inspecting energy-consumption greatly.
