Abstract
An adjustable 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 a rectangular frame, and at least a pair of opposite frame walls of four frame walls is provided with installation slots adapted to install the installation mechanisms. The installation slots positioned at different frame walls are in a same cross section of the rectangular frame. 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.
