Abstract: The disclosure provides a downhole anchoring apparatus for use in a downhole tool. An example downhole anchoring apparatus may include a housing with a hub provided within the housing. The hub may be arranged to rotate in a bi-directional fashion about a longitudinal axis. The downhole anchoring apparatus may also include a deployment linkage. The deployment linkage may be coupled to the hub by a hinge so that when the hub is rotated in a first direction, a distal end of the deployment linkage is extended radially outward from the central axis, and when the hub is rotated in a second direction, the distal end of the deployment linkage is retracted toward the central axis.

Abstract: A modular, mechanical percussive hammer assembly may be used with drill strings, wireline cable, and coiled tubing. Rotation of a splined driveshaft by downhole electric, hydraulic or mud motor rotates a downwardly-biased hammer and drill body rotatively captured within a upwardly-biased stationary anvil. A bit is carried by the drill body. The hammer contacts and rotates along a cammed control surface of the anvil as the driveshaft is rotated. Interaction between the cammed control surface and the hammer operated to create an axial impact force that is transmitted to the drill body and drill bit.

Abstract: The disclosure provides a downhole anchoring apparatus for use in a downhole tool. In an example implementation, a system is provided to anchor downhole tools in a wellbore. The system may include a tool body that fits within a wellbore casing, a slip having a wedge surface, a linkage connecting the slip to the tool body, and an actuator assembly. The actuator assembly may include a first actuator having a wedge surface corresponding to the slip wedge surface and a second actuator having a wedge surface corresponding to the slip wedge surface.
