we saw the need to improve the spooling of wire rope on the
Drilling Rigs began trying different methods and eventually created
the "LeBus" pattern which is still the best method used today for
spooling multiple layers of wire rope evenly and accurately. With
LeBus now supplying its products to all industries that need to
spool multiple layers of rope, LeBus still remembers where it began
and goes above and beyond to support the Oilfield with LeBus
Grooving, and much more. To this day LeBus is still used on
practically every Drilling Rig and Workover Rig in the world. .

The structural point of the LEBUS groove
The drum rope groove of drill winch adopts the form of double
broken line structure, and its characteristics are diagonal rope
groove and straight rope groove appear alternately, thus forming
two diagonal rope groove area and two straight rope groove area on
the surface of the drum. The so-called inclined rope groove refers
to the rope groove that intersects diagonally with the drum bus,
and the straight rope groove refers to the rope groove that
intersects directly with the drum bus or is parallel to the flange.
Diagonal strong groove controls the pitch of rope groove, which
accounts for a small proportion in a circle of rope groove. Its
structure point can effectively alleviate the problems of extrusion
deformation, mutual friction and early wear of wire rope during
loading.
The processing and production of the lebus groove can be directly
processed on the drum as a whole, and can also be made into a set
with the rope groove, and made into a split type, wrapped in the
smooth drum when installed, connected with the drum through bolts
or welding. The material of folding rope groove barrel can be
divided into carbon steel, stainless steel, alloy steel, aluminum
or glass fiber, etc. The barrel can be made by sheet rolling or
casting.
Double drum winch
In order to meet the requirements of drilling technology and
transportation, the winch is usually designed as a multi-shaft
drive and separate transportation, which not only makes the system
complex, but also increases the cost and installation workload. To
this end, the transmission scheme of the winch, power input mode
and the structure of the winch frame have done pioneering work, my
company designed a multi drums winch. The winch is mainly composed
of base, winch frame, roller shaft, sand drum shaft, shaft drive
boxes, disc brake, crash-proof crown device, main brake mechanism
and automatic driller, etc, and power shift between the input shaft
and the shaft adopts mechanical transmission, drive shaft and
roller shifting between adopts pneumatic clutch to shift, with four
are blocked, reverse gear. Finite element software was used to
simulate and analyze the drum shaft and check its strength and
stiffness. The analysis and check results show that the design of
the drum and frame of the winch is reasonable and meets the
practical work requirements.
