| 摘 要： | 针对现有钢丝绳损伤检测采用人工检查或定期换绳的方法,存在效率低、成本浪费严重及安全性差等问题,设计了螺线管式磁感应钢丝绳断丝检测系统。系统检测原理:当钢丝绳出现断丝时,磁导率会相应降低,磁阻变大,电感量减小,从而导致线圈磁场不平衡并产生感应电动势,根据该感应电动势的大小可判断出钢丝绳断丝的状况。试验结果表明,该系统克服了传统电磁检测技术不能精确检测钢丝绳内部出现断丝的缺陷,检测精度可达95%以上。

| Abstract: | In view of problems of low efficiency,serious wasting cost and poor safety of existing steel rope damage detection methods which using artificial method to inspect and regularly replacing steel rope,a detection system of solenoid magnetic induction for broken steel wire rope was designed.The detection theory of the system is:when broken wire occurs,the permeability will be reduced accordingly,reluctance increases,and the inductance decreases,and then induced electromotive force will be generated because of the imbalance magnetic field of coil.According to the induced electromotive force,the situation of broken wires can be determined.The experiment results show that the system overcomes defects that traditional electromagnetic detection technology cannot accurately detect internal broken wire rope,and accuracy can reach above 95%. |
