Modularized
Mechanical Drilling Rigs
■ The power transmission system is designed to
adopt the mode of diesel engine + hydraulic coupler (torque converter) +integral
chain compound box, featuring high driving efficiency and reasonable power
distribution.
■ The modules of 4000m or above rigs are laid
out in the way of front high rear low, and the power and transmission system will
be installed in the low position. The rotary table is driven by a universal
shaft.
■ The drawworks is designed to have an integral
chain driving mechanism, remote air-controlled mechanical gear-shifting. A hydraulic
disc brake (a band brake is optional) is adopted to be main brake, an eddy
current brake as auxiliary brake.
■ The substructure is designed to be of
piled-box-type, or swing-up type.
■ The compound box can be fitted with
energy-saving generator and automatic blower.
■ Independent driller control cabin,
centralized electric / air /hydraulic controls, unified layout of instruments
will ensure driller's intelligent and simple operations.
■ Intelligent control over traveling block, to
avoid collision and bumping.
■ An integral guiding rail can be fitted for
cluster well operations.
■ Network electric drive rigs are also
available (motor hydraulic) coupling set for electric motor).
