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.
