The invention discloses a hoisting sheave structure of a mining hoist. The hoisting sheave structure comprises baseplates, installation blocks, threaded columns, top plates, a carrier roller, limit holes, a hoisting sheave main body, a guard plate, clamping blocks, fastening bolts, limit mounting plates, limit bolts, a hoisting sheave mounting plate, cylinders, worm gears, worms and adjusting handles. The carrier roller of the hoisting sheave structure can be adjusted by using the principle of worm-and-gear transmission and the characteristics of a thread, so that the steel wire rope winding and the hoisting sheave main body are always in the best contact state, the service life of the steel wire rope winding is prolonged, the replacement frequency is reduced, and thus, the cost is saved;meanwhile the frictional force of the steel wire rope winding and the hoisting sheave main body and the working efficiency of the hoist are ensured; and during maintenance, the limit bolts can be inserted into the limit holes of the hoisting sheave main body so as to prevent the condition that other personnel accidentally open the equipment to cause injury to maintenance personnel, and thus, the safety of the maintenance personnel is guaranteed.
本发明公开了一种矿山提升机天轮结构,包括底板、安装块、螺纹柱、顶板、托辊、限位孔、天轮主体、护板、卡块、紧固栓、限位安装板、限位栓、天轮安装板、圆筒、蜗轮、蜗杆和调节手柄。本发明安装有托辊,利用蜗轮蜗杆传动的原理以及螺纹的特性,可对托辊的高度进行调节,从而使得钢丝绳绕线与天轮主体一直处于最佳的接触状态,延长了钢丝绳绕线的使用寿命,减少了更换的次数,从而节省了成本,同时保证了钢丝绳绕线与天轮主体的摩擦力,保证了提升机的工作效率,在检修时,可将限位栓插入天轮主体的限位孔内,避免了其他人员误开设备对检修人员造成伤害情况的发生,保障了检修人员的生命安全。
