Underground vertical or inclined shafts can be used to lift coal, materials, personnel, and equipment for lowering materials, and can also be used for other traction and transportation purposes. Executive standards: AQ1033-2007, JB/T7888.1-1999, and Q/HBSHM002-2009.

When starting the main motor, the power is transmitted to the high-speed shaft of the reducer through an elastic coupling by the motor rotor. After being driven and decelerated by the reducer, it is then transmitted to the main shaft device through a gear coupling by the passive shaft of the reducer. If the direction of the motor is constantly changed, the drum can be wound or the steel wire rope can be loosened, causing the lifting container to move up and down periodically in the wellbore.

The representation method of product model:

The method of indicating the model of the hoist should comply with the provisions of MT/T 154.8-1996.

The main shaft device of the lifting winch consists of a fixed drum, a movable drum (only for double drum use) main shaft, two bearing seats, a rope adjustment mechanism (only for double drum use), and other parts, used for winding or releasing steel wire ropes. The steel wire rope of the single drum lifting winch is an upper rope, the movable drum of the double drum lifting winch is a lower rope, the fixed drum is an upper rope, and the drum is equipped with lining wood.

The drum of the hoist is designed according to the new elasticity theory, and high-strength low-alloy steel Q345A is selected as the shell material. There are two types of connections: integral welding and partial bolt connection. For the convenience of maintenance or replacement during operation, it can also be made into a split type.

The two ends of the spindle are equipped with adjustable double row roller bearings, which are efficient and easy to disassemble and maintain. At this point, this series of mine hoisting winches has achieved full rolling transmission for all rotating parts, so the overall efficiency of the machine is over 90%, making it an energy-saving mine hoisting winch.
