A fixing device for acoustic emission test sensors for rock damage testing, the device including: a fixing frame, installation bases operating to accommodate the acoustic emission test sensors, respectively, fixing assemblies operating to fix the acoustic emission test sensors in the installation bases, and installation mechanisms operating to install the installation bases on the fixing frame. The fixing frame is an integrated loop-shaped frame. Each of the installation bases is a cylinder structure which includes: a cavity corresponding to an outer edge of each of the acoustic emission test sensors, and a wall including a gap for leading out wires of each sensor. The installation mechanisms are adapted to automatically and axially adjust positions of the installation bases. The installation mechanisms are four in number. The four installation mechanisms are disposed on a same section plane of the fixing frame and every two installation mechanisms are oppositely disposed.

1. A fixing device for acoustic emission test sensors for rock damage testing, the fixing device comprising: a) a fixing frame;b) installation bases, the installation bases operating to accommodate the acoustic emission test sensors, respectively;c) fixing assemblies, the fixing assemblies operating to fix the acoustic emission test sensors in the installation bases; andd) installation mechanisms, the installation mechanisms operating to install the installation bases on the fixing frame;wherein:the fixing frame is an integrated loop-shaped frame;each of the installation bases is a cylinder structure; the cylinder structure comprises: a cavity corresponding to an outer edge of each of the acoustic emission test sensors, and a wall comprising a gap for leading out wires of each sensor;the installation mechanisms are adapted to automatically and axially adjust positions of the installation bases; the installation mechanisms are four in number; the four installation mechanisms are disposed on a same section plane of the fixing frame and every two installation mechanisms are oppositely disposed; and two lines connecting installation positions of the oppositely disposed installation mechanisms meet at right angles, so that two lines connecting centers of end faces of oppositely disposed sensors pass through a diameter or a section center of a test piece;each of the installation mechanisms comprises: a sliding bar in fixed connection with each installation base; a spring which is sleeved on the sliding bar and has one end acting on each installation base and the other end acting on an inner wall of the fixing frame; and a support base fixed on an outer wall of the fixing frame;the support base adopts a structure of a guide tube and is perpendicularly fixed on the outer wall of the fixing frame; an inner diameter of the support base matches an outer diameter of the sliding bar to form a sliding pair; andthe sliding bar travels through an installation hole on the fixing frame and is axially slidably disposed in the guide tube; and a position-limit structure is disposed on a part of the sliding bar protruding from the guide tube for limiting axial sliding of the sliding bar. 2. The device of claim 1, wherein the position-limit structure for limiting the axial sliding of the sliding bar is formed by threads arranged on the sliding bar and a mating nut. 3. The device of claim 2, wherein the fixing frame is an integrated circular loop-shaped frame or an integrated rectangular loop-shaped frame. 4. The device of claim 2, wherein an angle of the gap of the cylinder structure of each of the installation bases is less than or equal to 120°. 5. The device of claim 2, wherein each of the fixing assemblies comprises: a split ring spring for binding each acoustic emission test sensor in each installation base, and a locking structure for locking the split ring spring. 6. The device of claim 5, wherein the locking structure is a clasp locking structure. 7. The device of claim 5, wherein the locking structure is a bolt-nut locking structure. 8. The device of claim 1, wherein the position-limit structure for limiting the axial sliding of the sliding bar is formed by a pin hole arranged on the sliding bar and a mating pin. 9. The device of claim 8, wherein the fixing frame is an integrated circular loop-shaped frame or an integrated rectangular loop-shaped frame. 10. The device of claim 8, wherein an angle of the gap of the cylinder structure of each of the installation bases is less than or equal to 120°. 11. The device of claim 8, wherein each of the fixing assemblies comprises: a split ring spring for binding each acoustic emission test sensor in each installation base, and a locking structure for locking the split ring spring. 12. The device of claim 11, wherein the locking structure is a clasp locking structure. 13. The device of claim 11, wherein the locking structure is a bolt-nut locking structure.
