Extended Wire Rope Slippy Cable winch Drum for Lift object
Signle / Double Drum Winch Description
Drum is one of the important parts of lifting machinery, used to wind wire rope in lifting mechanism or traction
mechanism.By transferring the driving force provided by the hydraulic or
electric drive device to the wire rope, the rotary motion of the
drive device is transformed into the linear motion required.
Drum Classification
1. According to the number of winding layers:
1) Single winding: Only 1 layer of wire rope is wound on the drum, spiral groove is
usually cut on the drum surface.
2) Double winding: The drum is wound with 2 layers of wire rope, spiral grooves or
lebus grooves can be used.
3) Multi-winding:Multilayer wire rope winding on the drum, used for particularly
large lifting height or compact mechanism occasions, the surface of
the drum cutting lebus grooves.
2. According to the processing method:
1) Casting Drum:The casting material is usually cast steel or cast iron.
2) Welding Drum:The drum core is made of seamless pipe or rolled with steel plate,
welding flange and drum core, and eliminating welding stress before machining.
3. According to the number of drum segmentation
1) Double winding:Two wire ropes can be wrapped around a drum.The rope can be wound
in the same direction or in the opposite direction
2) Multi-winding:The surface of a drum is divided into several drums by baffles,
each of which can be used separately for winding rope.
Four drum hoist, four hook hoist. Four wire ropes are fixed on a drum, respectively, from the drum,
from the bottom of the drum, when the drum rotates, one lifting
container up, the other container down.
Structural components
Drum, drum shaft assembly, which is the core components of the
winch.
Braking mechanism, including mechanical brake and water brake
(electromagnetic brake).
Cat head and cat head shaft assembly, used for tightening loose
wire buckle, lifting heavy objects; The heavy rig winch also
includes a bailing drum for extracting the core barrel.
Transmission system, the introduction and distribution of power and
transfer of motion, for the internal variable speed winch in
addition to the transmission shaft and drum shaft, cat head shaft,
but also including chains, gears, shafting parts and turntable
intermediate transmission shaft.
Control system, including teeth, teeth, pneumatic clutch, driller
console, control valve parts, etc., is an integral part of the rig
control system
Lubrication systems, including butter lubrication, drip lubrication
and seal drive, splash or forced lubrication.
A support system with a welded frame or shell frame.
