松绳法更换钢丝绳牵引带式输送机驱动轮的实践

Practice on replacing driving pulleys of belt conveyors drawn by steel ropes by rope slacking method

针对用传统方法更换钢丝绳牵引带式输送机驱动轮耗时长、效率低、严重影响生产等缺点,根据长期的生产实践,提出了不断绳更换驱动轮的松绳法。介绍了松绳法的原理、工作过程以及有关参数的确定方法。该方法在平煤一矿得到了成功应用。

In view of such defects on traditional replacement of driving pulleys of belt conveyors drawn by steel ropes as time-consuming,inefficiency and severe influences on production,a method of replacing driving pulleys by slacking ropes without breaking ropes is proposed according to long-term production practices.The paper introduces the principle,working process and approaches of determining relevant parameters of the rope slacking method which has been successfully applied in No.1 Colliery of Pingdingshan Tian＇an Coal Mining Co.,Ltd.
