Three-axis clamping device applicable to high-temperature and low-temperature cycle and medical CT (Computerized Tomography) machine

Abstract

The invention discloses a three-axis clamping device applicable to a high-temperature and low-temperature cycle and a medical CT (Computerized Tomography) machine. The three-axis clamping device comprises an outer barrel body, and further comprises a first oil injection part and a second oil injection part, wherein a barrel-shaped first inner connection part and a barrel-shaped second inner connection part sleeves oil outlet ends of the first oil injection part and the second oil injection part respectively; a fluorine rubber sleeve is located in the outer barrel body and two ends sleeve the first inner connection part and the second inner connection part respectively; a test sample, and a first clamping piston and a second clamping piston which are located at two sides of the test sampleare arranged in the fluorine rubber sleeve; the outer barrel body is provide with an oil/gas connector. The three-axis clamping device disclosed by the invention is simple in structure and compact instructure; a test sample loading process is simple and has high operability; the three-axis clamping device is small in size and can be put into the medical CT machine to carry out computerized tomography; the fluorine rubber sleeve is used as a rock sample packaging material and the material has good sealing performance and a high pressure-bearing capability under a low-temperature condition so that the three-axis clamping device is applicable to high-temperature and low-temperature cycle testing conditions.

Description

technical field [0001] The present invention relates to the technical field of rock mechanics test equipment, more specifically to a triaxial holder suitable for high and low temperature cycles and medical CT machines, and a rock sample triaxial loading device matched with medical CT machines, suitable for high and low temperature cycles Triaxial compression loading fixtures for variable test chambers and CT tomography. Background technique [0002] Frost heaving, thawing and shrinking of soil and rock exist in low-temperature geotechnical engineering, low-temperature geological storage of liquefied natural gas and petroleum gas, and freezing construction. Scholars at home and abroad have tried to study the problem of frozen rock through various methods such as in-situ and laboratory tests, and have achieved many good results. However, the research on frozen rock is far from mature, and many studies are still in the experimental and exploration stage. [0003] Among them, t...
