Description
Technical field
The present invention relates to triaxial tests instrument, more particularly to a kind of triaxial tests instrument test specimen apparatus for measuring quality.
Background technology
Triaxial tests instrument (being called three-axis tester) is a kind of common test apparatus in laboratory, passes through axial system pair
Test specimen applies axial sample power, applies confining pressure to test specimen by balancing gate pit, while makes the upper and lower of test specimen by temperature control system
End face is in different temperature environments in the middle part of test specimen respectively, so as to simulate a variety of actual conditions such as the freezing of test specimen, freeze thawing.
In the triaxial test of test specimen, the mass loss rate of test specimen is also a magnitude of necessary observation sometimes, and general measure quality is damaged
The method of mistake rate is the quality with the test specimen of poor quality divided by former of test specimen after experiment before testing, and is in this way, but testing in principle
For the quality of room measurement test specimen using balance, this just inevitably brings error, after the error and triaxial test on reading
Test specimen is often damaged to cause error caused by the loss of quality so that obtained mass loss rate is inaccurate.For this purpose, to have
Effect solves the above problems, and develops a kind of device of triaxial tests instrument test specimen mass measurement as urgent problem to be solved.
The content of the invention
For the problem of test specimen measurement error is brought in the prior art, the present invention provides a kind of triaxial tests instrument test specimen matter
Measuring device, for reducing the error that test specimen mass measurement is brought.
The technical solution adopted by the present invention to solve the technical problems is：A kind of triaxial tests instrument test specimen mass measurement dress
It puts, the triaxial apparatus stress room including triaxial tests loading system, for placing test specimen further includes：
The quality signal of test specimen for detecting the quality of test specimen, and is transformed into electric signal by quality testing unit；
Quality output unit, for exporting quality information；
The quality testing unit is arranged on triaxial apparatus stress room bottom, and the quality testing unit is defeated by the result of detection
Go out to the quality output unit.
Further, the quality testing unit is pressure sensor.
Further, the quality output unit is quality display instrument or voice broadcast unit.
Further, the output terminal of the quality testing unit is electrically connected by lead with the quality output unit, institute
It states and is correspondingly arranged on fairlead on quality testing unit.
Further, the triaxial tests loading system includes axis pressure system, confining pressure system and low-temperature control system.
Compared to the prior art, the invention has the advantages that：
1st, since the present invention is by setting the quality testing unit, and the quality testing list in triaxial apparatus stress room bottom
Member exports the result of detection to the quality output unit so that the present invention can substitute traditional balance measurement mode, to examination
Part not only avoids error in reading, test specimen crushes and quality is caused to damage after the test in the forward and backward carry out mass measurement of triaxial tests
The step of losing the error brought, substantially increase the accuracy of test specimen measurement, also reducing artificial measurement test specimen quality, operation letter
Just, conventional efficient is substantially increased.
2nd, the quality testing unit has the characteristics that detection is accurate, at low cost preferably using pressure sensor；The matter
Output unit is measured preferably using quality display instrument, has the characteristics that testing result intuitive display understands.
The present invention is described in further detail with reference to the accompanying drawings and embodiments；But a kind of triaxial tests instrument of the present invention
Test specimen apparatus for measuring quality is not limited to embodiment.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Specific embodiment

Quality output unit, for externally exporting quality information；
The quality testing unit is arranged on 6 bottom of triaxial apparatus stress room, and the quality testing unit is by the result of detection
It exports to the quality output unit.
In the present embodiment, the quality testing unit is pressure sensor 4, and the quality output unit is quality display instrument
1, the quality real-time display of test specimen can be come out.The output terminal of the pressure sensor 4 passes through lead 2 and the quality display instrument
1 electrical connection, and fairlead 3 is correspondingly arranged on the pressure sensor 4, for lead 2 to be connected to pressure sensor 4,
In order to the dismounting of device.
In the present embodiment, the triaxial tests loading system 7 includes axis pressure system, confining pressure system and low-temperature control system,
It is the prior art, therefore is not repeated further.
A kind of triaxial tests instrument test specimen apparatus for measuring quality of the present invention, uses pressure sensor 4 come test experience institute
The quality of the test specimen 5 (such as rock) needed, under the action of 5 gravity of test specimen, pressure sensor 4 turns the quality signal of test specimen 5
Become measurable electric signal, and shown through quality display instrument 1, experimenter only need to directly read from quality display instrument 1
Number.Specifically, operating method of the invention is as follows：
1) quality display instrument 1 and pressure sensor 4 are linked together by lead 2, and quality display instrument 1 is carried out compared with
Zero；
2) test specimen 5 is put into triaxial apparatus stress room 6, at this point, the reading M1 on record quality display instrument 1；
