Problems solved by technology
However, the current heating and cooling recovery system for hydraulic oil is not perfect, and some experimental devices are not even equipped with a cooling system, which causes some high-temperature hydraulic oil to be directly recycled into the oil tank, causing the oil tank to be deformed by heat. Affects devices near fuel tanks

The invention discloses a rock torsional shearing-pressing comprehensive experimental device. The device comprises a rack, a torsional shearing assembly, a loading assembly and an oil path system, wherein the torsional shearing assembly comprises a torsional loading oil cylinder, an end part of the torsional loading oil cylinder is put into a mounting sleeve, and the bottom of the mounting sleeve is rotationally mounted on a movable partition board through a mounting sleeve supporting shaft; a torsional telescopic shaft of the torsional loading oil cylinder is fixedly connected with a drive guide end of a torsional drive plate; a sliding guide shaft is fixed at the drive guide end, and the bottom of the sliding guide shaft is assembled in a torsional guide groove in the movable partition board; a torsional drive end of the torsional drive plate and a torsional part of a loading rod are assembled together. With the design of a clamping assembly, a sample can be rapidly assembled or disassembled and can be clamped reliably. A cooler is additionally arranged on the oil path system, recovered hydraulic oil can be quickly cooled due to the structural design of the cooler, and accordingly, equipment damage caused by excessively high temperature of the hydraulic oil is prevented.
Description
technical field [0001] The invention relates to a rock mechanics experiment device, in particular to a rock torsional shear-compression comprehensive experiment device. Background technique [0002] The stress changes of the rock during the mining process are very complicated. Generally, the axial direction is mainly tested by a triaxial testing machine, and the stress in the axial direction of rotation needs to be tested by a hollow column torsional shear instrument. However, in the prior art, only unidirectional stress tests, such as axial and radial, can be performed, and there is no device that can test axial and radial forces simultaneously. However, the stress of rock under the ground is very complicated. If only one-way stress test is carried out, it is difficult to restore its real stress situation. big security risk. [0003] In addition, the existing hollow column torsional shear instrument is mainly bonded and fixed to both ends of the sample by gluing. This met...
