Derrick-drawworks unit cluster drilling rigs

摘要

The invention relates to oil and gas equipment, namely drilling rigs designed for multiple drilling of exploration and production wells for oil and gas, provided with a mechanism for moving the derrick-winch unit for guide rails. Moving mechanism comprises an actuator and pivotally coupled to the base balancer wheeled trolleys, each of which comprises a housing and mounted on the wheel shafts are located along the rail. In the transverse direction relative to the rail wheel bogies balancer form paired wheels. Drive transfer mechanism is in the form of at least one pair of motor-reducers. The housing of each geared motor is mounted on a track located outside of the housing equalizer trolley so that the gear motor output shaft is connected to the shaft of the respective wheel pair. With each gear motor includes a built-in brake. In a particular case, each gear motor is configured with an electromagnetic brake and a hollow output shaft which is spline connected to the shaft of the respective wheel pair equalizer trolley. Securing each geared motor on the housing equalizer trolley provided flange. The technical result of the utility model is to simplify the design displacement mechanism derrick-winch unit and to reduce the time to move from one well to another. Furthermore, the use of displacement drive mechanism in the form of gearmotors eliminates the laborious manual operations when moving. NP 1, ZP 2, 4 Fig.
