Mechanical introduction
Mine elevator refers to the main transportation equipment connecting the mine and the ground in mining engineering. Mine hoist is installed on the ground, with the help of steel wire rope to drive the lifting container along the shaft or slope of the lifting machinery. It is used for lifting coal, ore, gangue and lifting personnel, lowering materials, tools and equipment in vertical and inclined shafts.
Machine construction
Mine hoist is mainly composed of working mechanism, braking system, mechanical transmission system, lubrication system, observation and operation system and dragging, control and safety protection system.
Technical feature
Adopting various types of drums, including integral, two-piece, and four piece types;
1.The drum rope groove adopts processed spiral rope groove, folded line rope groove, or spiral rope groove pressed with wood lining and plastic lining, and a steel rope transition device is set between the ropes;
2.Adopting a rear mounted disc brake with oil cylinder and electric hydraulic joint control; Hydraulic stations are divided into two types: medium low pressure and medium high pressure. There are two types of medium and low pressure hydraulic stations: constant braking force electrical delay and hydraulic delay two-stage braking; There are two forms of medium and high pressure hydraulic stations: constant deceleration and constant braking torque two-stage braking. The hydraulic station can be equipped with pressure sensors and pressure relays;
3.The spindle and drum are connected by flat high torque friction connection.
Advantages of our products
Lifting height is not limited: The lifting height of the multi-rope friction hoist is not limited by the width of the drum, and is suitable for deep well lifting1.
Equipment size and weight reduction: Since multiple wire ropes bear the terminal load together, the diameter of the wire rope can be reduced, resulting in a significant reduction in the diameter of the friction wheel, and the size and weight of the entire hoist will be reduced12.
More flexible selection of motors and reducers: Under the same lifting speed, higher speed motors and smaller transmission ratio reducers can be used12.
Steadyness during lifting: The even number of wire ropes are twisted half to the left and half to the right, which reduces the torsion of the lifting container during the lifting process, thereby reducing the friction between the tank ears and the tank channel12.
