摘要
建国以来,煤矿用国产2米以上大型矿井提升机约达2000多台,主要型式有单绳缠绕式和多绳摩擦式两种。成批生产的单绳缠绕式的卷筒直径达5米(单台达6米),配用煤矿容器有效载荷立井箕斗达12吨,提升速度14米/秒。单绳缠绕式大型矿井提升机,已制订了部标准,单台提升能力可满足设计年产量120~150万吨以下矿井生产的需要。多绳摩擦式矿井提升机。
The present status of home made large mine hoists are analyzed. Efforts are concentrated on the following aspects: in the field of single rope wound hoists, improving the drum structure, parallel rope groove for multiple layer winding, development of radial tooth type rope adjusting clutch, adoption of keyless connection, development of epicyclic reducer, improvement of disc brakes, development of high performance disc brake shoes, power-pack for secondary brake and use of mechanical micro-drive; and in the field of multi-rope hoist, improvement of guide wheel, developing low speed, directly connected suspension DC motor and control devices for determining the position of the hoisting containers.
The author holds that new variety of products should be developed in order to meet the needs of mines,such as ground mounted multi-rope friction hoists, series of flameproof underground hoists and series of hoists for shaft sinking. Finally, technical transformation of the existing hoists and developing complete set of equipment are dealt with.
