Abstract: A loading platform for a rock mechanics test system (MTS) to realize simple and reliable connection between a high temperature and high pressure force sensor in a triaxial chamber cavity and an upper solid rigid column. The loading platform for rock mechanics test includes a master rod, a secondary rod and a stop sleeve sleeved on the master rod; the stop sleeve is provided with two corbel structures; the secondary rod is composed of a secondary rod head body and a secondary rod body; a circular magnetic block is fixed on the secondary rod to adsorb a hole alignment sleeve sleeved on the secondary rod; and the hole alignment sleeve marked with a first scale line and a second scale line.

Abstract: A triaxial high temperature and high pressure rock mechanics load test platform includes a base, a lifting seat, and an intermediate connecting seat arranged between the base and the lifting seat. A hydraulic assembly is arranged between the base and the intermediate connecting seat; the intermediate connecting seat is connected with the lifting seat by means of a group of connecting rods; the lifting seat is enclosed by a side wall and a base plate to form a receiving groove with an upward opening; and a limiting device is arranged on the side wall of the lifting seat for preventing an MTS triaxial force sensor from disengaging from a support disk.

Abstract: A bearing system for rock mechanics test under high temperature and high pressure multi-field coupling includes a force sensor lifting seat and a jack. The force sensor lifting seat includes a connecting disk connected with the jack, a support disk, and an operation channel. A groove dented downwards is arranged on the connecting disk, the support disk is disposed in the groove and freely propped upon the connecting disk; through holes of the connecting disk and the support disk form a control operation channel; and a limiting device is arranged for preventing an MTS triaxial force sensor from disengaging from the support disk. A bolt hole of the force sensor can be aligned with a mounting hole on a solid steel column by rotating the connecting disk for convenient and accurate bolting.
