Winch drum is an important part of oil rig winch, winch drum
One end of the wound wire rope is fixed at the drum rope socket
through a rope clip, and the other end
The guide wheel of the sky car is introduced into the trolley
pulley group, and the trolley pulley group is installed
Equipped with hooks, faucets and drill pipe strings. When the winch
works, it is wound
The steel wire rope on the drum realizes the action of winding and
releasing the rope through positive and negative rotation of the
drum
The drum bears the fast rope tension of the wire rope, and the drum
structure must meet the strength
Outside, but also to ensure that the wire rope winding neatly.
With the development of oil drilling winches in recent decades,
winches appear more
The transmission form and the structure form, but the winding rope
rule of the winch drum is not change, our company developed LEBUS
rope groove has obvious advantages. LEBUS rope groove double line
form, suitable for multi-layer winding, can effectively reduce or
avoid steel wire Rope disorder phenomenon. In the design process of
the drawworks drum, the drawworks drum has a large opening range
Small, bottom diameter selection, position of guide block, rope
socket structure, rope groove spacing, rope groove the spiral Angle
of the parallel section and the climbing section will affect the
effect of drum rope winding, becauset this, the study of winch drum
structure and characteristics, will help to reduce or avoid oil
field field hoist drum disorderly rope phenomenon, prolong the use
of wire rope and drum life.

LBS grooved drum, solved the problem of wire rope spooling.
Compared with ordinary cordless groove (smooth) drum and helical
rope groove drum, LBS rope groove has obvious advantages in the
multi-layer wire rope spooling, LBS special groove system makes the
spooling of wire rope smooth, and the load of each layer evenly
distributed, extend the service life of rope, reduce the wire rope
damage, improves the safety of the operation of the equipment, and
reduces the problem of mechanical equipment shutdown for changing
rope.
1. The flanges of drum shall be perpendicular to drum wall at any
conditions,even under the load.
2. The rope must be kept under tension in the process of spooling
so that the rope will be crushed against groove wall. When spooling
can not meet this condition,a press roller shall be used.It is
generally recommended that the tension of the rope should be at
least 2% breaking tension or 10% working load.
3. The fleet angle range should generally never be more than 1.5
degrees and not less than 0.25 degrees.
4.When the wire rope released from the drum goes around the
sheave,the center of sheave should be over the center of drum.
5.The rope must be kept round,not loose,even under the maximum
load.
6.The rope must be anti-rotation structure.
7.Pls measure the change of rope diameter under different load.
