TEST BENCH OF ENERGY INTERCHANGE IN BLOCK ROCK MASS Russian patent published in 2016 - IPC E21C39/00 G01N3/10 

FIELD: test equipment; mining.

SUBSTANCE: invention relates to devices of energy interchange at deformation and destruction of block of rock mass. Test bench comprises support frame, with arranged in it sample and counter-sample grippers, hydraulic mechanism of mutual pressing samples, connected with hydraulic mechanism of reciprocal displacements of samples, connected with counter specimen gripper, hydraulic energy accumulators connected with mechanisms of pressing and displacement, pressure sources connected with appropriate storage batteries, pressure pulsators connected with appropriate storage batteries and arranged in form of hydraulic cylinders with rods, which below piston cavity is connected with appropriate storage batteries, cams, kinematically connected with hydraulic cylinder rods, cams rotation shafts and shafts rotation drives. Shafts are aligned, and test bench is equipped with electromagnetic couplings for connection of shafts with appropriate drives and electromagnetic coupling for connection of shafts between themselves.

EFFECT: expansion of scope of information at investigation of energy exchange by providing tests both at independent pulsation pressing and moving loads and synchronous pulsation with smooth and stepped change of pulsation frequency to control displacement of pulsation cycles during tests.
