《煤矿安全规程》第367条第二项规定:“使用中钢丝绳的定期试验,只作每根钢丝的拉断和弯曲试验,这二项指标按公称直径计算,当不合格钢丝的断面积和新绳钢丝总断面积之比达到25％时,必须更换。”按规程要求如何合理地切取提升钢丝绳作定期试验的试件以避免造成浪费是值得探讨的。据了解,一般提升钢丝绳的切取位置是取在与提升容器连接的最上一副绳卡子上方2～5m处,并且按此切取位置来确定新钢丝绳的选择长度。这一方法不能真正反映整根钢丝绳的使用状态。经过长期观查和试验发现:天轮对钢丝绳寿命的影响要比钢丝绳所受张力的影响大 “Coal Mine Safety Regulations,” the second paragraph of Article 367: “The use of steel wire rope regular test, only for each wire breakage and bending test, these two indicators by nominal diameter, when the unqualified wire cross-sectional area and The ratio of the total cross-sectional area of ​​new ropes to 25% must be changed. ”It is worth discussing how to properly cut the test pieces of ropes to make regular tests to avoid wastage. It is understood that the general position of lifting wire rope is taken in the lifting of the container connected to the top of a rope clamp 2 ~ 5m Department, and click here to determine the location of the new rope length selection. This method can not really reflect the entire state of use of wire rope. After a long period of observation and testing found that: the impact of the Celestial Wheel on the life of the rope than the tension of the rope
