Publication number: 20240011361Abstract: A gripper mechanism for a downhole tool is disclosed that includes an eccentric linkage mechanism. In operation, an axial force generated by a power section of the gripper expands the linkage mechanism, which applies a radial force to the interior surface of a wellbore or passage. A sliding portion allows the gripper to slide along a surface of the formation in response to the radial force applied to the interior surface of the wellbore or passage.Type: ApplicationFiled: March 17, 2023Publication date: January 11, 2024Inventor: Rudolph Ernst Krueger, V

Patent number: 9988868Abstract: A gripper assembly for anchoring a tool within a downhole passage and for possibly assisting movement of the tool within the passage. The gripper assembly includes an elongated mandrel and flexible toes that can be radially displaced to grip onto the surface of the passage. The toes are displaced by the interaction of a driver slidable on the mandrel and a driver interaction element on the toes. In one embodiment, the toes are displaced by the interaction of rollers and ramps that are longitudinally movable with respect to one another. In another embodiment, the toes are displaced by the interaction of toggles that rotate with respect to the toes.Type: GrantFiled: December 21, 2015Date of Patent: June 5, 2018Assignee: WWT NORTH AMERICA HOLDINGS, INC.Inventors: Duane Bloom, Norman Bruce Moore, Rudolph Ernst Krueger, V
