Winches are mainly used for traction in metal mines, coal mines, construction engineering departments, or for lifting heavy objects in oil fields. So how many winches do you know? Below is a list of common types for everyone to choose from:
Explosion proof winch, used for underground or ground loading and unloading scheduling, grouping, transportation in intermediate tunnels, and other auxiliary transportation. The winch adopts planetary gear transmission. This winch has the characteristics of compact structure, good rigidity, high efficiency, easy installation and movement, smooth start-up, flexible operation, reliable braking, and low noise. It can be used in situations where there is a large amount of biogas or coal dust present. Due to the protective device on the winch drum, the use and operation of the entire machine are very safe and reliable.
Column rotary winch, also known as slow winch, is used for column rotation in underground coal mines and roof covering of coal mining faces. Due to its low height and light weight, it is particularly suitable for thin coal seams and steeply inclined coal seam mining faces, as well as various mining faces, to recover metal columns that have sunk to the ground or been buried by coal and stone. With the improvement of mechanized coal mining, it is widely used in mechanized coal mining working faces as the installation, recycling, and traction of various equipment and spare parts.
The vertical winch is driven by a spherical worm gear pair, with a compact structure and small volume. It has a symmetrical structure and a long strip shape, with a sled shaped base that can move smoothly and flexibly in the well; The base has good rigidity and can be used for the top of columns and ground anchors. It is easy to install, stable to operate, and safe and reliable. This series of winches is mainly used for lifting coal, ore, stone, and lifting personnel, materials, tools, and equipment in vertical and inclined shafts.
The overall structure of the mining winch adopts a linear arrangement of the drum, reducer, and motor. The main components include: spindle device, reducer, hydraulic disc brake, hydraulic station, depth indicator device, speed measuring and generating device, mechanical centrifugal speed limiting device, control console, and electronic control equipment.
Sinking winches are mainly used to suspend suspension plates, water pumps, water pipes, grouting pipes, air ducts and other driving equipment and tensioning ropes during vertical shaft excavation in coal mines, metal mines and non-metal mines. The winch is mainly used to replace the tail rope connected between the two cages of the hoist; Replacing the flat rope can also be used as a vertical shaft winch, which has the same performance as a vertical shaft. The structure of this series of winches is wound type, mainly composed of spindle device, reducer, elastic coupling with brake wheel, working brake, safety brake, machine base, electric motor, etc.
