凡口铅锌矿副井为多绳摩擦式提升机,提升机电控为NT型全数字直流电控系统。副井提升机担负着生产人员升降、生产材料设备及矿石的运输工作,不仅直接关系到人的生命安全,又有种类繁多且载荷变化不定的物料运输,每次提升的载荷都可能不一样。1提升系统概况凡口矿副井提升机主要参数如表1所列。由于提升载荷不确定,关系到制动时钢丝绳的滑动问题。根
Fankou lead-zinc mine auxiliary shaft for multi-rope friction hoist, hoist electromechanical control for the NT-type digital DC electronic control system. Auxiliary elevator hoist is responsible for the production personnel movements, production of materials and equipment and ore transport, not only directly related to human life and safety, there are a wide range of loads and variable load transport of materials, each lifting load may be different. 1 to enhance the system profile Where mine shaft auxiliary hoist main parameters listed in Table 1. As the lifting load is uncertain, it is related to the sliding problem of the steel wire rope during braking. root
