Patent number: 8708607Abstract: A rock bolt comprising a shaft having first and second ends, and an anchoring device operative to retain the bolt when located in a drilled hole and comprising a mandrel mounted to, or integrally formed with, the shaft and at least one expansion element overlaying the mandrel, at least one of the mandrel or the at least one expansion element being a movable member and being able to rotate relative to, and move axially along, the shaft, the at least one expansion element being arranged to be displaced radially outwardly on a predetermined relative movement between the mandrel and the at least one expansion element, wherein when disposed on a first portion of the shaft, rotation of the movable member relative to the shaft causes axial movement of that member along the shaft, and when disposed on a second portion of the shaft, the movable member is able to rotate on the shaft without being biased to move axially along the shaft.Type: GrantFiled: July 9, 2008Date of Patent: April 29, 2014Assignee: Sandvik Intellectual Property ABInventor: Matthew Kenny

Patent number: 8403600Abstract: A drilling tool incorporating first and second ends, a shaft extending between the ends. The first end has a drill bit to penetrate rock. The drill bit and the shaft have complementary threads. The drill bit and the shaft comprise a relative rotation stop means that ensures that the drill bit remains loose during drilling in a first direction. The invention further relates to a self drilling rock bolt, a drill bit, drill shaft and shaft coupling, an anchoring device, and an end coupling per se.Type: GrantFiled: October 26, 2007Date of Patent: March 26, 2013Assignee: Sandvik Intellectual Property ABInventors: Steven Weaver, Darren Webb, John Horsch, Matthew Kenny

Patent number: 8061935Abstract: The present invention relates to a rock bolt comprising first and second ends, a shaft extending between the ends, and an anchoring device extending along a first part of the shaft adjacent the first end. The anchoring device comprises a mandrel, and at least one expansion element overlaying the mandrel. The expansion element is displaced radially outwardly on a predetermined relative movement between the mandrel and the expansion element. The expansion element is joined to a connector to form an anchor assembly. The anchor assembly is keyed to the mandrel. The anchor assembly comprises relative rotation actuator means active during rotation of the anchoring device. The invention further relates to an anchoring device per se.Type: GrantFiled: October 23, 2007Date of Patent: November 22, 2011Assignee: Sandvik Intellectual Property ABInventors: Steven Weaver, Darren Webb, John Horsch, Matthew Kenny

Patent number: 7963616Abstract: A cutting pick comprising an elongate shank and a cutting tip which is mounted to one end of the shank to project from that end. At least two sleeve segments are provided and those segments are circumferentially fixed about the shank to form a substantially annular sleeve. The sleeve can be fixed about the shank in non-contacting relationship with the trailing end of the cutting tip. Moreover, the cutting tip can have a portion of maximum diameter which is of greater diameter than the inner diameter of the sleeve so that the portion of maximum diameter overlies the sleeve radially.Type: GrantFiled: December 20, 2007Date of Patent: June 21, 2011Assignee: Sandvik Intellectual Property ABInventors: Steven Lee Weaver, Matthew Kenny

Patent number: 7896580Abstract: A self drilling rock bolt incorporating a shaft and an anchoring device. A first end of the bolt has a drill tip to penetrate rock and a second end is adapted to be connected to a drilling apparatus to allow rotation of, and thrust to, the bolt. A circulation passage is provided to allow fluid to be passed to the drill tip and in one form a central passage is formed in the shaft to form part of this circulation passage. The anchoring device is operative to retain the bolt when located in a drilled hole and comprises a mandrel having one or more inclined external surface mounted to, or integrally formed with, the shaft and at least one expansion element overlaying the mandrel. The expansion element(s) is displaced radially outwardly on a predetermined relative movement between the mandrel and the element.Type: GrantFiled: November 8, 2006Date of Patent: March 1, 2011Assignee: Sandvik Intellectual Property ABInventors: Steven Weaver, Darren Webb, John Horsch, Matthew Kenny

Publication number: 20100098500Abstract: A drilling tool (10) incorporating first and second ends, a shaft (13, 90) extending between the ends. The first end has a drill bit (15) to penetrate rock. The drill hit and the shaft have complementary threads. The drill bit and the shaft comprise a relative rotation stop means (82, 83) that ensures that the drill bit remains loose during drilling in a first direction. The invention further relates to a self drilling rock bolt (10), a drill bit (15), drill shaft (13,90) and shaft coupling (94), an anchoring device (23), and an end coupling (95) per se.Type: ApplicationFiled: October 26, 2007Publication date: April 22, 2010Applicant: SANDVIK INTELLECTUAL PROPERTY ABInventors: Steven Weaver, Darren Webb, John Horsch, Matthew Kenny
