多绳摩擦式矿井提升机设计
摘要
矿井提升系统是矿井运输设备的重要组成部分,是矿山运输的咽喉。多绳摩擦式提升系统在现代矿山行业中的应用十分广泛,矿井提升系统的类型很多,按被提升对象分:主井提升、副井提升;按井筒的提升道角度分:竖井和斜井;按提升容器分:箕斗提升、笼提升、矿车提升;按提升类型分:单绳缠绕式和多绳摩擦式等。我国常用的矿用提升机主要是单绳缠绕式和多绳摩擦式。我国的矿井与世界上矿业较发达的国家相比,开采的井型较小、矿井提升高度较浅,煤矿用提升机较多,其他矿(如金属矿、非金属矿)则较少。
多绳摩擦式矿井提升机主要由电动机、减速器、摩擦轮、制动系统、深度指示系统、测速限速系统和操纵系统组成,采用交流或直流电机驱动。采用低速电动机时可不用减速器,电动机直接与卷筒主轴相连,或将电动机转子装在卷筒主轴的末端。

Abstract
Mines along the wellbore lifting equipment for coal and gangue, lifting ascension devolved materials, personnel and equipment of large mechanical equipment. It is of mines production system and ground industrial square connected hub, mining transport throat. Therefore, the mine production equipment in the ascension of the utmost importance. In addition, mine shaft hoisting equipment is a prehensive machinery electrical equipment, its cost and power consumption is higher, so, in the new design of mine and the old mines to key design, the determination of reasonable lifting equipment, must go through various technical and parison, combined with the specific conditions of mine, ensure lifting equipment selection and operation in two aspects are reasonable, which requires mine with economy lifting equipment.
Mine elevator equipment ponent is: promote capacity, lifting rope, hoist (including drag control system), derrick (or Wells tower), changeless unloading equipment and install.
Key word:lifting equipment;maintenance;variable frequency speed rejuvenation;output speed
