Patent number: 10533379Abstract: A down-the-hole drilling device, being meant for drilling a hole with and a casing part is described. The drilling device comprises in its drilling head: a drilling arrangement, having first drilling means for drilling a center hole and second drilling means for reaming the center hole for the casing part; and a flushing flow arrangement for feeding of a flushing medium onto a drilling surface of the drilling arrangement by one or more feed channels and for discharging the same from the drilling surface together with drilling waste. The casing part is arranged to be pulled into the hole to be drilled by power influence directed thereto from the drilling arrangement. A feed channel of the flushing flow arrangement at least partly ends up on the drilling surface at a flushing channel that exists in the longitudinal direction of the drilling device essentially behind a rearmost part of the drilling surface of at least of the first drilling means.Type: GrantFiled: February 13, 2015Date of Patent: January 14, 2020Assignee: TerraRoc Finland OyInventor: Kai Gylling

Patent number: 10428603Abstract: A method for putting together a down-the-hole drilling apparatus for plastic pipe drilling. The down-the-hole drilling apparatus has a drilling device for carrying out drilling by using a drilling unit with a plastic pipe, which drilling unit includes in its drilling head a drilling arrangement. The plastic pipe is arranged to be pulled into the hole to be drilled by a power influence directed thereto from the drilling unit, being coupled with the second drilling means in a manner transmitting power at least in the longitudinal direction of the drilling device. The drilling unit and the plastic pipe are coupled by a skirt part that exists at an opposite end of the drilling arrangement, with respect to the drilling surface of the drilling unit, which skirt part has an internal protrusion assembly in radial direction.Type: GrantFiled: June 4, 2015Date of Patent: October 1, 2019Assignee: OY EPIROC DRILLING TOOLS ABInventor: Kai Gylling

Patent number: 10024108Abstract: A drilling device for a down-the-hole drilling apparatus. The drilling device includes in a guide, a drilling member and a flushing mechanism configured to flush drilling waste. The drilling mechanism includes first and second drilling bit arrangements that are movable with respect to the drilling device and that are arranged to be expanded to drill a hole having a greater cross-sectional surface area than an end of the casing and arranged to be reduced to a size smaller than the end of the casing. Bit pieces of the second drill bit arrangement expand and reduce the second drill bit arrangement. The bit pieces expand the second drill bit arrangement by moving in a radial direction outwards in slide grooves, by rotating the guide in a drilling direction, and move in the radial direction inwards in the slide grooves, by rotating the guide in an opposite direction.Type: GrantFiled: July 2, 2014Date of Patent: July 17, 2018Assignee: OY EPIROC DRILLING TOOLS ABInventor: Kai Gylling

Patent number: 9970238Abstract: A method for assembling a down-the-hole drilling apparatus including a drilling device including a casing and a drilling unit arranged during drilling in connection with the casing. The drilling unit includes a drilling head including a drilling arrangement including a first drilling member for drilling a center hole and a second drilling member for reaming the center hole. The drilling members are mutually power transmittingly coupled during drilling to cooperate for rotational, feeding and/or hammering, and removably coupled to enable removal of the first drilling member from a hole. The casing is arranged to be pulled into the hole through a shoulder arranged at an end of the casing. At an opposite end of the drilling arrangement with respect to a drilling surface, is arranged a skirt including a radial internal shoulder for pulling the casing into the hole by cooperation of the internal shoulder and an external shoulder at the end of the casing.Type: GrantFiled: May 15, 2014Date of Patent: May 15, 2018Assignee: OY ATLAS COPCO ROTEX ABInventor: Kai Gylling

Patent number: 9611701Abstract: A drilling method and apparatus. A drilling device includes a plastic casing part and a drilling unit arranged essentially inside the casing part. The drilling unit includes a first drilling part for drilling a center hole and a second drilling part for reaming the center hole for the casing part. The drilling parts are arranged at a drilling head. The drilling parts are coupled in a power transmitting manner or in a radially contractable manner in connection with the casing part. A casing shoe is mounted at an end of the casing part. In coupling of the casing shoe at an end of the casing part, a casing shoe is used that includes a working member. The casing shoe is mounted at the end of the casing part by treating the casing part to provide a joint between the casting part and the casing shoe that transmits pulling.Type: GrantFiled: October 30, 2012Date of Patent: April 4, 2017Assignee: OY ATLAS COPCO ROTEXInventor: Kai Gylling

Publication number: 20160201409Abstract: A method for assembling a drilling device. A first drilling member is power transittingly, coupled with a second drilling member during drilling for rotational, feeding and/or hammering motion, and removably coupled to remove the first drilling member from a hole. A casing is pulled into the hole by power from the second drilling member transmitted through a shoulder between the casing and second drilling member. The shoulder enables independent rotation of the casing and second drilling member and restricts mutual longitudinal movement thereof. A casing shoe is fastened at an end of the casing and includes an internal or external counterpart shoulder in the radial direction of the shoulder. A separate sleeve minimizes radial expansion of an outermost structural part in the drilling device and/or kinetic energy transmitted by counterpart shoulders. Also, a drilling device.Type: ApplicationFiled: August 20, 2014Publication date: July 14, 2016Applicant: OY ATLAS COPCO ROTEX ABInventor: Kai Gylling

Patent number: 9175519Abstract: A method for coupling an earth pipe into the ground when utilizing an apparatus that has a drilling device including a casing part and a drilling unit inside thereof. The drilling unit includes a first drilling member for drilling a center hole and a second drilling member for reaming the center hole for the casing part. The casing part is arranged to be drawn into the hole by the first and/or second drilling member. After drilling a hole for the earth pipe and lifting up the first drilling member, a solidifying mass is led to the bottom of the hole to couple the earth pipe to the surrounding ground. The solidifying mass is brought in the casing part utilizing a flow-through assembly at a lower end of the casing part into a space between an outer surface of the casing part and the hole. Also an apparatus operating.Type: GrantFiled: November 1, 2011Date of Patent: November 3, 2015Assignee: Oy Atlas Copco Rotex AbInventor: Kai Gylling
