分析了西曲矿选煤厂706刮板机频繁发生断链事故的原因,通过应用两种高强度链条安全系数的计算方法对刮板机链条的强度分别进行了验算校核,并对两种不同的计算结果进行比较与分析,得出了传统方法计算过程繁琐且考虑因素不全面,计算出的安全系数可靠程度偏小。根据第二种方法的计算结果,结合生产现场实际情况,采用一套简单、经济、可靠、易行的技术改造方案,将其最大运输量由800 t/h 提高到了1200 t/h,提高了刮板机运行的安全可靠性,消除了断链事故,保证了安全生产。
分析瞭西麯礦選煤廠706颳闆機頻繁髮生斷鏈事故的原因,通過應用兩種高彊度鏈條安全繫數的計算方法對颳闆機鏈條的彊度分彆進行瞭驗算校覈,併對兩種不同的計算結果進行比較與分析,得齣瞭傳統方法計算過程繁瑣且攷慮因素不全麵,計算齣的安全繫數可靠程度偏小。根據第二種方法的計算結果,結閤生產現場實際情況,採用一套簡單、經濟、可靠、易行的技術改造方案,將其最大運輸量由800 t/h 提高到瞭1200 t/h,提高瞭颳闆機運行的安全可靠性,消除瞭斷鏈事故,保證瞭安全生產。

Analyzes the reasons why 706 scraper conveyor chain rupture accident happened frequently in Xiqu coal mine preparation plant.Two kinds of high strength safety coefficient computing method are applied to check scraper conveyor chain strength,and the two kinds of different calculation results are compared and analyzed.Obtains that the calculation process of traditional method is cumbersome and consideration is not comprehensive,the reliability of safety coefficient is small.According to the calculation result of the second method,combines with the actual pro-duction situation of the field,uses a set of simple,economic,reliable,feasible technical transformation scheme,the maximum transport capacity increased from 800 t/h to 1 200 t/h,improve the safety and reliability of scraper convey-or operation,eliminate the broken chain accident,ensure safety in production.
