DRILLING PLANT Russian patent published in 2005 - IPC

FIELD: construction industry.

SUBSTANCE: device has base moving carriage with frame, driving actuators, volumetric hydraulic drive with pumps and driving engines for actuators of left and right boards and stopping brakes with mechanism for controlling these, and also of, mounted on frame of moving carriage via manipulator, feeder frame with rotation gears and traction of drilling base along well axis with hydraulic engines of drives of these mechanisms, while hydraulic rotation engines of drilling base and its feeding gear during drilling are connected to pumps of right and left board instead of actuator drives hydraulic engines, via two-positional holders, which are controlled together with stopping brakes. If brakes are made with braking hydraulic cylinders and control holder for these, two-positional holders are made with hydraulic control, and inputs into chambers for control thereof are connected by mains to input into braking cylinders of stopping brakes. To combine possibilities of drilling vertical and/or horizontal well suspension gear is made in form of four-assembly device, on joints, with hydraulic cylinder for slanting feeder frame, which device is supported by means of transverse beam. To provide for possible drilling at corners of rectangular pit, feeder frame is fixed in intermediate guide of support gear with possible longitudinal displacement, and transverse beam of suspension gear is made symmetrical relatively to longitudinal symmetry plane of carriage.

EFFECT: higher efficiency.
