The invention discloses a gearbox suspension type locking disc connection small module drilling
winch, and relates to the field of
oil field drilling and repairing
machine operation equipment. A winchis driven by an alternating-current variable frequency motor, a gearbox transmits power, a main
brake is a hydraulic
disc brake, an auxiliary
brake is a main motor
energy consumption brake, a brake disc is installed on the left side of a single roller shaft, and the right side is connected with the gearbox through an idle sleeve suspension type locking disc locking structure. The
winch is composed of the roller shaft, a
machine frame, a
disc brake, a
shock absorber, a locking disc, the gearbox, a
drill feeding device, a coupler, an angle box, a motor, a lubricating
system, an alternating-current variable-frequency
control system and the like, the alternating-current variable-frequency motor drives the angle box, a
winch shaft is driven by the gearbox, and a roller is driven to achieve ascending and descending of a
traveling block. An all-digital
vector control voltage source type alternating-current variable-frequency speed regulation device is adopted, a V / f characteristic curve frequency
control mode and a
magnetic field orientation
vector control mode are achieved, and the
drill feeding device is connected with a gearbox
clutch and is an independent driving
system.
