立井临时改绞混合提升设备选型计算

Equipment selection calculation ofvertical shafttemporary change mixed lifting

针对某基建矿井吊桶提升无法满足高效建设的现状,提出了双罐笼加双箕斗的混合提升临时改绞方案。通过选型计算和安全校验,确定了罐笼提升系统采用18×7-28-1770型钢丝绳、TXG2000/28型铸钢天轮、2JK-2.5/20型提升机,箕斗提升系统采用2JK-3.5/20型提升机的设备选型方案,并对其提升能力进行了计算。结果表明,立井临时改绞混合提升系统能够大幅提高矿井提升能力,缩短建井周期6个月,带来可观的经济效益,同时可为基建矿井立井提升提供理论基础和科学保障。

Sincea bucket hoist systemcan not satisfy efficient construction in mine construction stage,a mixed lifting scheme ofdouble cage with double skipin temporary change twist period isproposed. By computing and security check,equipment selection programis determined that the cage hoisting system uses a 18 ×7-28-1770 wire rope,TXG2000 / 28-type steel sheave,2JK-2.5 / 20-hoist,skip hoisting system uses 2JK- 3.5 / 20 hoist. , and its lifting capacity were calculated too. The results show that a mixed lifting scheme ofdouble cage with double skip in temporary change twist period can significantly increase lift capacity, shorten the construction cycle by six months, bring considerable economic benefits,and provide the theoretical basis and scientific support fora coal mine shaft hoist system construction.
