Abstract

The invention discloses a true triaxial rock test rig, comprising a frame base, wherein the bottom surfaces of two mutually parallel side support plates on the top surface of the frame base are connected fixedly, a frame top plate is fixed on the top surfaces of the side support plates; the top parts of four screw rods penetrate through the frame top plate and a lifting frame and are assembled with the frame base; the screw rods are screwed and assembled with the lifting frame through threads; the top parts of the screw rods extend out of the frame top plate, a screw rod belt pulley is fixed to each extending end, the four screw rods are connected with the screw rod belt pulleys at the top parts through a first lifting synchronous belt to form a belt driven structure, and one of the four screw rods is connected with another screw rod belt pulley and a motor belt pulley fixed to the output shaft of a lifting motor through a second lifting synchronous belt to form a belt driven structure; and a loading assembly is fixed in the lifting frame and comprises a loading shell, an adjusting screw hole is formed in the loading shell and a loading cavity is arranged in the loading shell. The invention also discloses a temperature control system and a temperature control method thereof of the true triaxial rock test rig.

Description

technical field [0001] The invention relates to a true triaxial rock testing machine, which is used for testing the mechanical properties of rock or concrete. [0002] The present invention also relates to the oil temperature control system of the true triaxial rock testing machine and the oil temperature control method based on the system. Background technique [0003] In the test of various mechanical properties of rock, the true triaxial rock testing machine is a commonly used equipment, which is mainly used to provide three directions and unequal pressures on rock samples or concrete samples, so as to simulate the rock in the formation. in the real stress state. In addition, the existing true triaxial rock testing machine generally needs to soak the sample in high-pressure or high-temperature and high-pressure oil to simulate the confining pressure and temperature suffered by the sample. [0004] In the Chinese invention patent with the application number 201510660510....
