麻家梁矿副立井提升机提升大型液压支架的实践

Practice of Lifting Large Hydraulic Support by Hoist in Assistant Vertical Shaft of Majialiang Mine

因综采工作面液压支架无法满足生产需求,改用了高性能液压支架,液压设备增大导致提升系统运行超载和制动安全系数降低,通过增加制动闸和更换首钢丝绳型号的方法,提高了提升机的提升能力和系统的安全可靠性能。

Because of hydraulic support of fully mechanized working face that is unable to meet the production requirements, the high performance of hydraulic support is used, increasing hydraulic equipment leads to the operation overload of hoisting system and the reduction of brake safety factor, by increasing the brake and changing the model of wire rope, the lifting capacity of hoist and the safe and reliable performance of system are improved.
