Articulation mechanism designed to conform substantially to the configuration of at least one surface adjacent to it and to maintain contact with it and tractor mechanism for contact with a tradi- tional surface.
Articulation mechanism designed to conform substantially to the configuration of at least one surface adjacent to it and to maintain contact with it and tractor mechanism for contact with a tradi- tional surface.
"JOINT MECHANISM FOR COMPLIANCE SUBSTANTIALLY WITH THE CONFIGURATION OF AT LEAST ADJUSTABLE SURFACE AND CONTACTING THE SAME AND TRACTOR CONTACT WITH A TRACTED SURFACE". It is a six-bar pivot mechanism to conform to the configuration of a traction surface and has a central pivot defined by a tool body and a support pivot spaced from the central and movable pivot for conformation to the surface. Tractioned. The mechanism includes a pair of front pivots having individually pivotable connections with respective ends of the support pivot and having linearly movable pivot connections with the central pivot to make possible angular and spacing changes of said support pivot to the central pivot. A pair of centering joints are located between the front joints and have pivotable connections with the support joint and pivotable connections with the central joint. One of the pivotable connections is linearly movable over the central joint. For tractor tools, when the traction surface is a borehole or a well pipe, a plurality of six bar joints radiate from the surface forming traction tool body to the traction surface.
