The invention discloses a loaded coal and rock mass heat-fluid-solid coupling CT triaxial pressure cavity lifting device. A loading unit for a triaxial test unit is formed; the triaxial test unit performs rock sample loading through a loading unit; the triaxial test unit is arranged on a loading table of the loading unit; a linear guide rail pair structure is formed between the loading table and the triaxial test unit; a moving driving device is arranged between the loading table and the triaxial test unit; the loading table is hinged onto a machine frame of the loading unit through a hinging structure; the lower end of one side of the machine table is provided with a workpiece loading table; when the triaxial test table is in a vertical state, the workpiece loading table is positioned right under the vertical state triaxial test unit. The loaded coal and rock mass heat-fluid-solid coupling CT triaxial pressure cavity lifting device has the beneficial effects that the triaxial test unit can be switched between the horizontal state and the vertical state; when the triaxial test unit is in the horizontal state and is matched with the CT scanning system, a CT scanning machine can be pushed in and pulled out in a push-pull mode; the configuration of lifting equipment is not needed; the operation is simple and convenient; the safety is high; in the vertical state, the loading and the unloading of the rock sample are convenient are safe.
