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 loading assembly. The rock loading assembly comprises a loading casing, wherein the acting part of a loading rod penetrates through a top sealing plate to be fixedly connected with a connection plate of an upper chuck assembly; the upper chuck assembly comprises clamping plates, and one of the clamping plates comprises a mounting drive part and a clamping semi-ring; a retainer comprises a fixing notch and a bottom sealing plate; the mounting drive part is clamped in the fixing notch, and one end part of the mounting drive part is closely attached to a clamping plate inner cavity of the corresponding clamping plate; the inner wall of one of the clamping plates comprises arc-shaped concave surfaces and arc-shaped bulged surfaces, and the arc-shaped concave surfaces and the arc-shaped bulged surfaces are distributed at intervals; the at least three clamping plates are uniformly distributed on the circumference of the retainer; the bottom of a sample is clamped on the upper chuck assembly at the bottom of the sample, the bottom of one clamping plate of the upper chuck assembly is fixedly connected with a supporting base, and the supporting base is arranged in a base mounting hole of a loading base; an oil distributing cavity is further arranged between the supporting base and a base sealing plate; the base sealing plate is communicated with the oil distributing cavity through a main oil inlet and outlet channel, and an oil inlet and outlet channel is communicated with a main oil inlet and outlet pipe.
Description
technical field [0001] The invention relates to a rock mechanics experiment device, in particular to a rock loading assembly. The present invention also relates to an experimental device using the rock loading assembly described above. 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 ma...
