阐述了漏磁检测技术检测钢丝绳的原理,设计了一种矿用电梯钢丝绳无损检测系统。该系统采用灵敏传感器检测钢丝绳两侧的漏磁通变化,并以ARM为基础平台开发了系统软件。经现场试验证明,该系统能有效地检测钢丝绳的断丝、磨损、颈缩、疲劳及锈蚀等缺陷,且检测数据可靠,大大降低了用绳成本和人工检测成本。 The principle of magnetic flux leakage testing is introduced, and a nondestructive testing system of mine elevator rope is designed. This system uses the sensitive sensor to detect the flux leakage on both sides of the steel wire rope and develops the system software based on ARM. The field test proved that the system can effectively detect the wire rope breakage, wear, necking, fatigue and corrosion defects, and the test data is reliable, greatly reducing the cost of rope and manual testing costs.
