1. Overview of traveling
block
The traveling
blockis a traveling system connecting
the crown blocks with wire rope. It can greatly reduce the fast
rope pull, in order to greatly reduce the load of boring winch in
various operations of the well drilling.
2. Function and
use requirements of traveling block
The traveling block is
a movable pulley unit that moves back and forth vertically inside
the derrick. Modern traveling blocks are provided with single
shafts, and multiple pulleys are mounted on a shaft with a rolling
bearing. The pulley rotates faster on the side of fast rope than
that on the side of dead rope, so the pulleys are worn differently,
and those closer to the fast rope are worn more seriously. To
resist wear, the rope groove shall be subject to surface heat
treatment. When the rope groove is worn seriously, the pulley shall
be changed.
3. Structure of
the traveling block
The traveling block is
mainly made up of beams, left and right side plates, pulleys,
pulley shaft, lower lifting rings and other components. Between the
left and right side plates of the traveling block, the pulley shaft
is equipped with pulleys to form the pulley block. Each pulley is
fitted with a roller bearing. To prevent the bearing from oil
leakage and dirt from entering the bearing, the oil baffle discs
are installed on both sides of the pulley. Each bearing has a
separate lubricating oil duct, and the oil cups on both ends of the
pulley shaft are filled with lubricating grease with oil gun. In
order to prevent the wire rope from jumping and protect the pulley,
shields are installed on both sides of the traveling block, and the
shields are provided with slotted holes for wire rope passing
through. The lower part of the pulley is covered with a fender.
