    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.

    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.

    Abstract: A device for fixing a rock sample, the device including: a lower clamp and an upper clamp. The lower clamp includes: a lower connector connected to a bottom loading base, a lower end cap for fixing samples, a lower chain connecting the lower connector and the lower end cap, a first spiral spring, a first central position-limit mechanism, and a second central position-limit mechanism. The lower end cap includes: a first sample fixing groove and a first connecting segment. The upper clamp includes: an upper connector connected to a top loading base, an upper end cap for fixing the samples, an upper chain connecting with the upper connector and the upper end cap, a second spiral spring, a third central position-limit mechanism, and a fourth central position-limit mechanism. The upper end cap includes a second sample fixing groove and a second connecting segment.

    Abstract: A rock specimen, including a rock body having the shape of a cylinder or a regular square prism. The rock body includes: an upper end face, a first circular groove, a first cylinder, a first circular body, a lower end face, a second circular groove, a second cylinder, and a second circular body. The first circular groove is disposed on the upper end face of the rock body and has a circle center coinciding with the center of the upper end face of the rock body. The second circular groove is disposed on the lower end face of the rock body and has a circle center coinciding with the center of the lower end face of the rock body. The outer diameter of the first circular groove is smaller than the inner diameter of the second circular groove, and the first circular groove and the second circular groove are staggered.
