TEST BENCH OF ENERGY INTERCHANGE IN BLOCK OF ROCK Russian patent published in 2018 - IPC G01N3/36 

FIELD: test equipment.

SUBSTANCE: invention relates to test equipment, devices of energy interchange at deformation and destruction of block of rock mass. Test bench contains a support frame,sample gripping device and counter-sample gripping device, arranged in the support frame, two hydraulic mechanisms in the form of cylinders with power pistons associated with the respective grippers, two pressure sources associated with the respective hydraulic mechanisms, pulsators associated with hydraulic mechanisms and including eccentrics, drives the rotation of eccentrics and pushers, kinematically associated with the pistons of the corresponding hydraulic mechanisms. Hydraulic mechanisms are equipped with additional coaxially executed pistons in terms of the number of pressure steps to be changed, placed in cylinders, coaxially with the corresponding pushers, retainers for connecting the additional pistons to each other, fixatives for connecting the additional pistons with the respective cylinders and retainers for connecting the additional pistons with the respective pushers. Pressure sources are connected to the cavities located between the power and the corresponding additional pistons.

EFFECT: technical result: the possibility of carrying out tests both smoothly and with step-change amplitude and the level of thrust and shear loads, as well as an increase in the amount of information in the studies.
