EQUIPMENT FOR ROCK FIELD RESEARCH Russian patent published in 2010 - IPC E21C39/00 G01N3/00 

FIELD: mining.

SUBSTANCE: equipment for rock field research, containing a cylindrical case, a bar installed on the case longitude axis, forces, installed perpendicular to the axis and cinematically connected with the bar's one end, a load, cinematically connected with the bar's another end; according to the invention a toe cam for interaction with the force installed on the bar's end, the toe cam and forces located in a case, which has a guide for moving along and rotation around the bar's axis, a rotation and moving displacement fixer and a fixed for the connection to the toe cam, the load hangs swiveling on the bar's end on a balance, with a fluctuation ability in the bar's axis dislocation plane and in a plane perpendicular to the bar's axis, at that the balance has a detachable swivel butt, connected to the case, but the bar connected to the balance with axial rotation ability.

EFFECT: information flow increase due to wells wall loading with a convergent oscillation load, convergent displacement of load application points perpendicular and along the wells axis, at the convergent oscillation load lines change along the well axis.
