矿井提升系统平衡锤质量选择的合理性探讨

Discussion on rationality of counterweight mass selection in mine hoisting system

以某金矿3号竖井罐笼配平衡锤提升机改造为例,以常规方法计算平衡锤质量,并核算各种工况时最大张力差、动静防滑安全系数、电动机功率。考虑“提升重载的张力差等于空罐运行的张力差,以满足防滑要求”,构建平衡锤计算模型,同时在平衡锤质量计算方法改进后,计算各种工况时最大张力差、动静防滑安全系数、电动机功率。对比分析两种计算方法,并结合应用实践,证明利用平衡锤质量改进算法所得到的平衡锤质量,是经济的、合理的、安全可靠的。

Taking the transformation of the hoist for the No.3 shaft cage with the counterweight in a gold mine as an example,the quality of the counterweight was calculated by a conventional method,and the maximum tension difference,the dynamic and static anti-skid safety coefficients and the motor power under various working conditions were calculated.Considering that the tension difference of the heavy load in hoisting was equal to the tension difference of operating with an empty cage,to meet the anti-skid requirements,the calculation model of the counterweight was constructed.At the same time,after the improvement of the mass algorithm of the counterweight,the maximum tension difference,the dynamic and static anti-skid safety coefficients and the motor power under various working conditions were calculated.Then,by comparing and analyzing the two calculation methods and combining with the application practice,it was proved that the counterweight quality obtained by using the counterweight mass improvement algorithm was economical,reasonable,safe and reliable.
