HIGH POWER UNIT DRILLING RIG

摘要

The invention relates to drilling rigs and can be used in the drilling rigs with top drive rotation, which are designed for operation in the mobile lifting units with capacity from 100 to 160 tons and are used for drilling and workover of oil and gas wells. The problem to be solved by the utility model is to provide a new upper actuator reliable construction (hereinafter GSP) with two high-torque hydraulic motors, for use in a mobile lifting device. Technical result of utility model is to improve the ease of maintenance, increasing the reliability of the design of the WWW. Upper actuator rig PVG-2000P comprises a swivel to a rotary drive, wherein the set gear, two high-torque hydraulic motor, the mechanism of the swivel deflection from the wellbore center-axis mounted on the carriage, lifting mechanism drill pipe, and is characterized in that one of the high-torque hydraulic motors mounted on the upper cover of the gear housing, and the other high-torque hydraulic motor mounted on the bottom of the gear housing, wherein said motors are arranged output shafts towards from each other and are connected via a gear with a transmission ratio close to unity with the output shaft of the swivel, which is arranged inside the feeder pipe. FIG. 1a more fully explains the utility model.
