FIELD: mining.
SUBSTANCE: drilling rig contains a drilling mast, a movable passing rotor that performs descent and lifting of the drill string, a drill pipe manipulator with the ability to move its grip to the accumulation site and back, a carousel barrel of a drum type, located on the opposite side of the movable rotator, providing for the drill pipe to be extended upwards from the next cell of the rack when the drill string is lowered or the drill pipe to be lowered onto its setback as it is raised. Reception, holding and release of the upper ends of the drill pipes in the cells of the rack automatically effected as a result of the force interaction of the moving drill pipes with the spring grips of the cells, as well as the stationery pipe screwing device. The drill pipes manipulator is located in the upper part of the mast with the possibility of rotating around its axis by 180º, as well as performing operations to install a drill pipe on the drill string when screwing with the column and detaching it from the latter while unscrewing, while the passing rotor, during screwing and unscrewing of the drill pipe by a pipe screwing device, performs its idle run of lifting and lowering, respectively, during columns lowering and lifting. The carousel pipe rack contains two rotating drum magazines located on a common base, which is rotatable about its axis, so that in the operating position of the drilling rig the vertical plane passing through the axes of these racks is located on its longitudinal axis, and in the transport position - perpendicular to this axis.
EFFECT: automation of running in and out with their time alignment, simplifying and increasing the reliability of the structure.
