Problems solved by technology

[0005] In order to study the acoustic emission characteristics of rocks, researchers need to arrange acoustic emission probes on the specimens. The common method of installing the probes is to tie them with adhesive tape and glue. Displacement; if glue is used, there is a problem of removing the glue, and the glue may corrode the probe, which is time-consuming and labor-intensive

Abstract

The invention discloses a fixing device of an acoustic emission probe for a rock uniaxial experiment. The device comprises a frame structure and a fixing structure, and the frame structure is fixedlyconnected with the fixing structure. The frame structure comprises a frame body and stabilizing blocks. The frame body is connected with the stabilizing blocks in a buckled mode. The frame body is also provided with positioning holes, and the positioning holes vertically penetrate through the frame body in the horizontal direction. According to the fixing structure, probe positions in various forms can be arranged as required, the frame structure is flexible and convenient to mount and dismount, the stability of threaded rods can be enhanced through the stabilizing blocks, the defect that a probe cannot be well attached to a test piece due to instability of the threaded rods caused by inaccuracy during machining of the positioning holes is overcome, and the frame body plays a role in forcetransmission and balance coordination.

Description

technical field [0001] The invention relates to a fixing device for an acoustic emission probe, in particular to a fixing device for an acoustic emission probe for a rock uniaxial experiment. Background technique [0002] With the acceleration of shale gas mining in my country, there are more and more problems, and the output cannot be increased. It may be that the mining technology and the nature of the rock are not enough. Here, researchers need to further understand some mechanical properties of rocks and cracks when they are destroyed. evolutionary features. [0003] Most materials are heterogeneous and defective. Under the action of external stress, the microelements with low internal strength will be destroyed when the local stress is concentrated to a certain extent, which will relax the local stress and cause stress drop, resulting in local area Rapid unloading, thus producing acoustic emission phenomenon. The same is true for rocks, so monitoring through acoustic e...
