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 device comprises a rack, wherein the rack comprises a base, rack side plates and a rack rear plate are fixed on the base, and a second partition board is arranged between the two rack side plates; a first partition board I, a movable partition board I, a movable partition board II and a first partition board II are arranged among the two rack side plates, the second partition board and a top plate; a first lateral mounting block and a first longitudinal mounting block are arranged on each first partition board; a second lateral mounting block and a second longitudinal mounting block are arranged on each movable partition board; the first lateral mounting blocks and the first longitudinal mounting blocks are fixedly assembled in a longitudinal mounting groove and a top mounting groove respectively, and the second lateral mounting blocks and the second longitudinal mounting blocks are assembled in the longitudinal mounting groove and the top mounting groove respectively; the longitudinal mounting groove and the top mounting groove are formed in the rack rear plate and the rack side plates respectively; a first lead screw, a second lead screw, a third lead screw and a fourth lead screw penetrate through the first partition board I, the movable partition board I, the movable partition board II and the first partition board II and rotationally assembled on the rack side plates at two ends.
Description
technical field [0001] The invention relates to a rock mechanics experiment device, in particular to a rock torsional shear-tension comprehensive experiment device. Background technique [0002] The stress changes of the rock during the mining process are very complicated. Generally, the tensile strength of the test sample can be directly stretched on a stretching machine, and the stress in the circumferential direction 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...
