Patent number: 9759020Abstract: A rod and rod cup alignment apparatus for a drilling machine has a receptacle for receiving a drill rod of the type having at least one rod flat, where the drill rod has a leading corner and a trailing corner relative to the direction of its rotation. The receptacle has at least one cup flat disposed on the inner surface of the receptacle and the cup flat further has a first top surface and a second top surface. The second top surface has a slope downward toward the bottom of the rod cup, so that, as the drill rod is lowered into the rod cup while the drill rod is rotating, the leading corner of the drill rod is caused to move downward along the second top surface, whereupon the trailing corner of the drill rod contacts the first top surface, thereby aligning the drill rod flat with the rod cup flat.Type: GrantFiled: January 22, 2016Date of Patent: September 12, 2017Assignee: Atlas Copco Drilling Solutions, LLCInventors: Donald W Smith, Luke Bender

Patent number: 9074424Abstract: A rod support system has an upper gripper assembly and a lower gripper assembly. Each gripper assembly has a top plate having a first track. The first track has a first substantially arcuate portion having a first radius of curvature and a second substantially arcuate portion having a second and smaller radius of curvature. A jaw is constrained to move in a path defined by the first track. A bottom plate of the assembly has a second track that is congruent with the first track also engaging the jaw, so that the jaw is constrained to move in a path defined by the first track and the second track in cooperation. The jaws can support a rod when the jaws move from a position along the first arcuate portion of the first and second tracks to a position along the second arcuate portion of the first and second tracks.Type: GrantFiled: May 16, 2012Date of Patent: July 7, 2015Assignee: Atlas Copco Drilling Solutions, LLCInventors: Andreas Jonsson, Chad Przano, Tim Ledbetter

Patent number: 8813870Abstract: An arrangement in a rock drill rig 10 has an inlet valve 31 arranged upstream from a displacement compressor 32 that is used for supplying an air flow 34 to at least one flushing hole 23 in the surface of a drill bit 20. The rock drill rig 10 also has an air regulator 35 arranged to regulate the system pressure in the air flow path 34 downstream from the compressor and a detector for detecting air flow through the at least one flushing hole 23 in the surface of the drill bit. The detector has a pressure sensor 36, arranged between the air regulator 35 and the inlet valve 31, for measuring the reduced system pressure.Type: GrantFiled: April 29, 2009Date of Patent: August 26, 2014Assignees: Atlas Copco Rock Drills AB, Atlas Copco Drilling Solutions LLCInventors: Deyi Jiao, Per Krainer

Patent number: 8782968Abstract: An interface apparatus between a tower and platform includes a tower support assembly with opposed angle brackets and a first tower support assembly coupler/decoupler which is repeatably moveable between coupled and decoupled conditions with the tower support assembly. In the coupled condition, the coupler/decoupler is capable of coupling to the tower support assembly at a plurality of predetermined positions along the opposed angle brackets. The interface apparatus includes a second tower support assembly coupler/decoupler which allows the tower to pivot relative to the tower support assembly and rotate relative to the platform.Type: GrantFiled: September 21, 2009Date of Patent: July 22, 2014Assignee: Atlas Copco Drilling Solutions LLCInventor: James M. Benson

Publication number: 20140151120Abstract: A drilling machine includes a compressor coupled to a prime mover through a hydraulic clutch, wherein the hydraulic clutch is repeatably moveable between engaged and disengaged conditions. The compressor is allowed to provide air and is restricted from providing air in response to the hydraulic clutch being in the engaged and disengaged conditions, respectively. The hydraulic clutch is moveable between the engaged and disengaged conditions during operation of the prime mover.Type: ApplicationFiled: February 10, 2014Publication date: June 5, 2014Applicant: Atlas Copco Drilling Solutions LLCInventors: Timothy Ledbetter, Iain A. Peebles

Patent number: 8622151Abstract: A drilling machine includes a feed cable system which operatively couples a rotary head to a tower. The feed cable system includes first and second pull up cables and an equalizer bar, wherein the equalizer bar is coupled to the first and second pull up cables. The equalizer bar drives the rotary head to be held in a level position so that it is restricted from tilting. The drilling machine includes a slack take up device which couples the equalizer bar to the tower. The slack take up device is repeatably moveable between extended and retracted conditions.Type: GrantFiled: September 21, 2009Date of Patent: January 7, 2014Assignee: Atlas Copco Drilling Solutions LLCInventor: Timothy W.
