摘要： A device for centering a sensor assembly in a bore comprises a plurality of arm assemblies connected first and second support members. Each arm assembly comprises a first arm pivotally connected to the first support member, a second arm pivotally connected to the second support member, and a third arm pivotally connected between the first and second arms. The third arm is pivotally connected to a third support member positioned axially between the first and second support members. The third arm extends across the longitudinal axis of the device so that in use each arm assembly contacts opposite sides of the bore to centralise the sensor assembly in the bore.

摘要： A core detection device of a coring instrument includes a base body and a core switch mechanism provided on the base body. The base body is provided with a core channel communicated with a core barrel. The core switch mechanism includes a detection portion, a connecting rod assembly and a travel switch which are sequentially arranged and connected along a length direction of the coring instrument. The detection portion is rotatably installed on the base body and one end thereof is extended into the core channel, so that a core passing through the core channel pushes the detection portion to rotate. The connecting rod assembly can be pulled by the rotating detection portion to trigger the travel switch to operate. The core switch mechanism adopts a slider-connecting rod structure, and the kinematic pairs are mainly a sliding pair and a rotating pair.

摘要： A high expansion anti-rotation anchor catcher includes a helical track positioned on an exterior surface of a tubular body. An expandable gripper cage is provided having an axially fixed hub mounted for rotation about the tubular body and an axially movable hub mounted for rotation about the tubular body. Pivoting linkages which support outwardly oriented grippers extend between the axially fixed hub and the axially movable hub. The axially movable hub has a track follower that engages the helical track on the exterior surface of the tubular body. Rotation of the tubular body in a first rotational direction causes the track follower to move along the helical track toward the axially fixed hub, thereby placing the expandable gripper cage in compression and causing the pivoting linkages and grippers to pivot outwardly away from the tubular body to secure the anchor in position.
