金鸡岩洗选厂货运索道全长1.82 km,钢丝绳直径34.5 mm。过去钢丝绳的检测只能靠人工,这样的检测方法存在以下问题:一是对钢绳的内部磨损、断丝以及锈蚀等损伤根本无法检测到,给索道的安全运行埋下隐患;二是检测耗时、耗力且部分缺陷难以发现,根据GB 9075-1988 要求,每进行一次人工检查需2～3人,耗时2.5～3 h (曼速0.5 m/s运行),特别是当钢丝绳使用到中、后期时,检测频率增多,所耗时间和人力随之增多,严重制约了索道的生产调控,并且人工检测时,处于高度集中状态,容易产生疲
The length of the freight ropes in Jinji Yan washing plant is 1.82 km and the wire rope diameter is 34.5 mm. In the past, the testing of wire ropes can only rely on manpower. Such testing methods have the following problems: firstly, the internal wear and tear of the ropes, the broken wires and the corrosion of the ropes can not be detected at all, thus laying hidden dangers for the safe operation of the ropes; secondly, When laborious and some defects are difficult to find, according to the requirements of GB 9075-1988, each time a manual inspection required 2 to 3, took 2.5 ~ 3 h (Man speed 0.5 m / s operation), especially when the wire rope to use In the middle and later periods, the detection frequency increased, the time and manpower increased, which severely restricted the production and control of the cableway. In the case of manual inspection, it was highly concentrated and prone to fatigue
