Schematic diagram.
Detailed description of the invention
It is as shown in Figure 1, 2, of the present utility model based on Brazil's diametral compression test acoustic emission probe fixing device,
Including the fixture 9 of clamp assay sillar 8, described fixture 9 include two disk clamping parts 1 and with described circle
The connecting rod 10 that dish clamping part 1 is connected, the end of described connecting rod 10 is provided with handle 6；
The outside of described disk clamping part 1 is provided with three boss 2, is provided with through hole 11, institute in described boss 2
State the thickness direction of through hole 11 through disk clamping part 1；Described through hole 11 inwall is provided with screw thread, through hole 11
It is threaded connection pressure cap 3.Subtended angle controller 7 and alligator clamp 5 it is respectively equipped with between described connecting rod 10,
Two disk clamping parts 1 are come closer by described alligator clamp 5, and described subtended angle controller 7 limits two disks
Clamping part 1 draw close angle.
The side of described boss 2 is provided with groove 21, and described groove 21 communicates with through hole 11.Groove 21 is used
In drawing acoustic emission probe connecting line.Described handle 6 is vertically disposed disk.The inwall of described pressure cap 3
It is provided with flexible pellet block 4.Pressure cap 3 includes the flexible pellet block 4 being arranged within pressure cap 3, can make probe
Avoid owing to screwing the pressure cap 3 abrasion to probe with rock sample 8 good contact simultaneously.
Through hole and pressure cap 3 all designs for buckle, can by rotating pressure cap 3, regulate acoustic emission probe and
The contact of rock sample 8.
Concrete operation step:
First pressure cap 3 is screwed down, then by handle 6 so that two disk clamping parts 1 of fixture 9
Open certain angle, then will need to carry out the rock sample 8 of Brazilian disc splitting at holder
Disc both sides.Through suitably adjusting, release handle 6.
Then suitable couplant is smeared on the probe of acoustic emission device by connecting, by the location designed
Point, by the probe placement numbered in advance in corresponding through hole 11.
Then screwing on pressure cap 3, suitable screws so that probe, couplant, rock test piece 8 are fully contacted.
Check again for device connection line, it is ensured that line is accurate, proceed by acoustic emission detection.
After having detected, pressure cap 3 of outwarding winding, takes out acoustic emission probe, cleaning probe and fixture 9, it is simple to
Next time is detected.
Embodiment described above is only to be described preferred implementation of the present utility model, the most right
Scope of the present utility model is defined, and without departing under this utility model design spirit premise, this area is general
Lead to various deformation and improvement that technical solutions of the utility model are made by engineers and technicians, this reality all should be fallen into
In the protection domain determined with novel claims.
