Abstract
The utility model discloses a pressure chamber structure of rock mechanics triaxial compression test machine, include the pressure chamber that forms by base and last barrel be equipped with relative up -down's upward pressure head and overdraft head in the pressure chamber, the upward pressure head is connected with last dummy piston, go up dummy piston with go up the sealed sliding connection of barrel upward be equipped with pressure oil access way on the dummy piston go up dummy piston with be equipped with the sensor between the upward pressure head, the overdraft head is connected with lower dummy piston, down dummy piston with the base seals sliding connection. The utility model discloses can measure required tentation data automatically and accurately to the data stabilization is reliable, under the high confined pressure condition, dummy piston's external diameter is gone up in the accessible adjustment, makes the pressure chamber inside because the axial force that the confined pressure produced carries out rational distribution to make the inside and testing machine frame of pressure chamber all at the best stress, can greatly reduce the weight and the volume of equipment.
Description
Technical field
The utility model relates to the research field of triaxial compression test machine in rock test, particularly the pressure chamber structure of three-axis tester in a kind of rock test.
Background technology
Rock-soil mechanics pilot system carries out the conventional test of scientific research, engineering detecting and checkout equipment to rock in current ground field, relate to the pressure chamber structure of triaxial compression test machine more, object is under modeling effort prototype stressing conditions, the situation of change of rock, strength test, relaxation test, creep test, overall process failure test etc. under these testing machines can complete uniaxial tension and under three Spindle Status; Can complete the high and low temperature test under three Spindle Status, pore water pressure is tested, and can complete Indirect Tensile Tests and the direct tensile test of rock under uniaxial tension.The parameter such as compressive strength, Poisson ratio, bullet mould of rock under the compressive strength of rock, Poisson ratio, bullet mould, shear resistance, pore water penetration index, sound wave transfer coefficient, high and low temperature environment can be detected.But traditional three-axis tester pressure chamber exists a lot of drawback: one pressure is little, under high-pressure situations (as loaded 100-150MPa confined pressure), testing requirements cannot be met; , very easily there is the inaccurate situation of test figure in the collection of its two data-signal and transmit not accurate enough; The loading system of its three pressure chamber, structurally, due to the restriction by input and transmission, general or be load below separately, load above separately, added by inside, pressure chamber, confined pressure loads excessive (100-150MPa), causes testing equipment volume and weight too huge.
Summary of the invention
The utility model provides a kind of pressure chamber structure of rock mechanics triaxial compression test machine for solving in known technology the technical matters that exists, this structure can meet testing requirements under high-pressure situations, and the collection of data-signal and transmission are accurately and reliably, when loading confined pressure and being identical, volume and weight is all less.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is: a kind of pressure chamber structure of rock mechanics triaxial compression test machine, comprise the pressure chamber formed by base and upper shell, upward pressure head opposing upper and lower and downforce head is provided with in described pressure chamber, described upward pressure head is connected with upper balance piston, described upper balance piston and described upper shell seal and are slidably connected, balance piston is provided with pressure oil access way on described, on described, be provided with sensor between balance piston and described upward pressure head; Described downforce head is connected with lower balance piston, and described lower balance piston and described base seal are slidably connected.
Described upper shell is provided with hole for hoist.
Described base and described upper shell with bolts.
The advantage that the utility model has and good effect are: adopt and be arranged on sensor collection between balance piston and upward pressure head and transmission of data signals in pressure chamber, can automatically and accurately measure required test figure, and data stabilization is reliable; In high confining pressure situation, by adjusting the external diameter of upper balance piston, make pressure chamber inner because the axial force of confined pressure generation carries out reasonable distribution, thus make inside, pressure chamber and testing machine framework all be in best stress, therefore, when loading confined pressure and being identical, the weight and volume of equipment can greatly be reduced.Further, the utility model structure is simple, and easy to operate, cost is low, and test effect is good, practical.
