FIXING DEVICE FOR ACOUSTIC EMISSION TEST SENSORS FOR ROCK DAMAGE TESTING

摘要

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.

1. A fixing device for acoustic emission test sensors for rock damage testing, the 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; and d) installation mechanisms, the installation mechanisms operating to arrange the installation bases on the fixing frame; wherein
the fixing frame is an assembled loop-shaped frame and comprises 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; and 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; 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.
