Material mechanical test machine is tested, to study the mechanical property of rock soil test piece, now to the research under rock sample temperature case
It is more and more, it will usually rock core test piece is put into nitrogen low-temperature (low temperature) vessel and freezed, then enters trip temperature thawing, research to test specimen again
The change of the mechanical property of test specimen.But test specimen when being freezed using nitrogen, often occurs that smooth base is tight in refrigerating process
Weight, but nitrogen is expensive, the wasting of resources is relatively serious, the direct face degree heating dress of test specimen in temperature melting process
Put, a certain degree of destruction is often caused to test specimen, so a kind of new rock core test piece freeze thawing device of design, on the one hand ensures examination
Part freezes thoroughly in refrigerating process, avoids the waste of nitrogen resource；On the other hand test specimen is avoided to be directly exposed in high temperature.
Utility model content
The new technical problem to be solved of this experiment is to provide a kind of new rock core freeze thawing device, it is intended to passes through sealing ring
Come seal case upper end cover and casing, realize the holding of freeze thawing unit temp, it is intended to the heating of test specimen is realized by resistance wire,
It is intended to be placed in single closed container by each test specimen, overcomes the shortcomings of conventional container efficiency is low, resource consumption is big, it is real
The high efficiency high quality of frozen process experiment is showed, has liberated manpower, shortened the work period.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of new rock core freeze thawing device, including case
Body upper end lid arrangement, box body device, induction installation, holder device, pipe connection device：Its feature casing upper end lid arrangement includes test specimen
Upper end cover, sensing hole, the mouth of pipe, seal boss and upper end cover, the test specimen upper end cover, seal boss, upper end cover are all overall
Process, the sensing hole, the mouth of pipe are all directly directly to be processed in upper end cover, and its feature box body device includes sealing
Circle, resistance wire, test specimen cylinder, cabinet shell, the sealing ring are placed in the groove of box body device inwall, and heater strip is fixed on case
The inwall of body, test specimen cylinder are welded on the bottom surface of cabinet wall, and induction installation is that temperature sensor and upper end cover pass through sensing hole mistake
It is full of cooperation.
Casing upper end lid arrangement includes test specimen upper end cover, sensing hole, the mouth of pipe, seal boss and upper end cover, described
Test specimen upper end cover, seal boss, upper end cover are all that overall processing comes out, and the sensing hole, the mouth of pipe are all directly in upper end cover
Directly process.
Beneficial effect using above-mentioned technical proposal is that the casing upper end cover realizes sealing to whole box body device,
The test specimen upper end cover realizes the sealing protection of test specimen, while the buffer action of test specimen, the seal boss and casing are matched somebody with somebody
Close and ensure box sealing.
The box body device includes sealing ring, resistance wire, test specimen cylinder, cabinet shell, and the sealing ring is placed on casing dress
Put in the groove of inwall, heater strip is fixed on the inwall of casing, and test specimen cylinder is welded on the bottom surface of cabinet wall.
Beneficial effect using above-mentioned technical proposal is to be put into sealing ring in the groove of cabinet wall to ensure sealing effectiveness, electricity
Resistance silk can realize the thawing of test specimen, and test specimen cylinder can protect test specimen to avoid direct contact with resistance wire.
The induction installation is temperature sensor.
