Description
Technical field
The utility model is related 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 making 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, 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, general measure quality damage sometimes
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
Room measures the quality of 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 developing a kind of device of triaxial tests instrument test specimen mass measurement becomes urgent problem to be solved.
Utility model content
For the problem of test specimen measurement error is brought in the prior art, the utility model provides a kind of triaxial tests instrument examination
Part apparatus for measuring quality, the error brought for reducing test specimen mass measurement.
Technical solution adopted by the utility model to solve its technical problems is：A kind of triaxial tests instrument test specimen mass measurement
Device, including triaxial tests loading system, the triaxial apparatus stress room for placing test specimen further include：
Quality testing unit, the quality for detecting test specimen, and the quality signal of test specimen is transformed into electric signal；
Quality output unit, for exporting quality information；
The quality testing unit is arranged in triaxial apparatus stress room bottom end, 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 end 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 utility model has the advantages that：
1, since the utility model in triaxial apparatus stress room bottom end by being arranged the quality testing unit, and the quality is examined
It surveys unit to export the result of detection to the quality output unit so that the utility model can replace traditional balance measurement side
Formula not only avoids that error in reading, test specimen is broken after the test makes to test specimen in the forward and backward carry out mass measurement of triaxial tests
The error brought at mass loss substantially increases the accuracy of test specimen measurement, also reduces the artificial step for measuring test specimen quality
Suddenly, easy to operate, substantially increase conventional efficient.
2, the quality testing unit preferably uses pressure sensor, has the characteristics that detection is accurate, at low cost；The matter
It measures output unit and preferably uses quality display instrument, have the characteristics that testing result intuitive display is illustrated.
The utility model is described in further detail with reference to the accompanying drawings and embodiments；But one kind three of the utility model
Axis experiment instrument test specimen apparatus for measuring quality is not limited to embodiment.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Embodiment, a kind of shown in Figure 1, triaxial tests instrument test specimen apparatus for measuring quality of the utility model, including

Quality output unit, for externally exporting quality information；
Quality testing unit setting is in 6 bottom end 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 end 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 that axis presses 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 utility model, reality is detected using pressure sensor 4
The quality for testing required test specimen 5 (such as rock), under the action of 5 gravity of test specimen, pressure sensor 4 believes the quality of test specimen 5
Number it is transformed into measurable electric signal, and is shown through quality display instrument 1, experimenter only need to be straight from quality display instrument 1
Connect reading.Specifically, the operating method of the utility model is as follows：
1) quality display instrument 1 and pressure sensor 4 are linked together by lead 2, and to quality display instrument 1 carry out compared with
