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 arrange the installation bases on the fixing frame. The fixing frame is an assembled loop-shaped frame and includes between two and four frame members and corresponding fixing structures; and the frame members are assembled into an integrated loop-shaped frame by the fixing structures. Each of the installation bases is a cylinder structure. The cylinder structure 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.
