Abstract
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.
