Description
Technical field
Basis is the most novel relates to a kind of square core clamping device.
Background technology
Current core clamping device is used to clamp cylindrical rock core, when cylindrical rock core makes, cores on rock with different angles, and the physical parameter such as the core permeability that obtains, intensity is very different, and therefore, can meet difficulty when carrying out some researchs；Such as, carrying out the characteristic research of rock different directions, be to drill through some rock cores with different angles on same sillar to study, this method drills through rock core difficulty, and not studies with same rock core, and result of study has deviation with actual；But square rock core can flip an angle, same rock core takes multiple measurements, and overcomes drawbacks described above.
Therefore, on the basis of cylindrical rock core clamper, design a kind of square core clamping device, rock different directions characteristic research demand can be met it can also be used to other relate to the correlational study such as the gas flow of the square rock core of stand under load, absorption parsing.
Summary of the invention
This is novel for a kind of square core clamping device, it is characterized in that, including round outside but spuare inside rubber bush, i.e. rubber bush is the most cylindrical, middle part is provided with cuboid hole, cuboid hole cross section is square, for placing core sample, rubber bush inner hollow, form a cavity, rubber bush embeds cylindrical tube, rubber bush is provided with pressurization interface 1, pressurization interface 1 extends cylinder, liquid on-load pressure can be pressed in cavity by pressurization interface 1, cylinder one end is provided with retaining groove, and be provided with gland and can snap in retaining groove, cylinder other end top is provided with pressurization interface 2, inside is provided with female thread, left rock core plug and right rock core plug it is respectively arranged at two ends with about clamping device, for closing grasping part.
Described left rock core plug, it is characterised in that left rock core plug is a cuboid, cuboid cross section is identical with rubber bush cuboid hole, can put in cuboid hole, is provided with venting channels in the middle part of left rock core plug, contacting one end with rock core and be provided with vent grooves, the other end is provided with ventilation line.
Described right rock core plug, it is characterised in that right rock core plug one end is cuboid, and cuboid cross section is identical with rubber bush cuboid hole, can put in cuboid hole, and cuboid is provided with cushion rubber；Remainder is cylinder, and including plug, guide rod, baffle plate, plug can slide on guide rod, is provided with baffle plate and prevents plug landing, and plug is provided with external screw thread, can screw in cylinder by the female thread that cylinder is provided with；Being provided with venting channels inside right rock core plug, venting channels cuboid one end is provided with vent grooves, and the other end is provided with ventilation line.
Accompanying drawing explanation

Wherein, 1-cylinder, 2-rubber bush, 3-cavity, 4-left rock core plug, the square rock core of 5-, 6-right rock core plug, 7-female thread, 8-plug, 9-baffle plate, 10-guide rod, 11-external screw thread, 12-cavity, 13-pressure interface 2,14-cushion rubber, 15-retaining groove, 16-gland, 17,18 ventilation line, 19 venting channels, 20-pressure interface 1,21-cuboid hole, 22-vent grooves.
Detailed description of the invention
The square core clamping device of one as shown in Figure 1, can realize the clamping of square shaped rock core by following steps, and (1) takes out left rock core plug 4 and right rock core plug 6, the foreign material of 21 in removing cuboid hole；(2) the square rock core 5 that will test puts into the correct position of cuboid hole 21 of rubber bush 2, is engaged with the female thread 7 of cylinder 1 by the external screw thread 11 on plug 8 by right rock core plug 6 and screws in cylinder 1, and the effect of cushion rubber 14 can prevent fluid seepage；Left rock core plug 4 inserts rubber bush 2, is stuck on retaining groove 15 by gland 16, and left rock core plug 4 is applied the effect of certain force by gland 16, in case gland 16 drops；(3) by the liquid of certain pressure, by 20 pressurization interfaces 1, it is pressed in cavity 3, outside then can be limited by cylinder 1, the most then can load certain confined pressure by square shaped rock core 5, by the liquid of certain pressure, by 13 pressurization interfaces 2, being pressed in the cavity 12 of right rock core plug 6 and cylinder 1 formation, fluid pressure will make plug 8 slide on guide rod 10, and thus square shaped rock core 5 loads certain axial compression.
If desired for being passed through gas, ventilation line 17 can be accessed source of the gas, gas by left rock core plug 4 venting channels 19 and and its top vent grooves 22 enter device, the gas penetrating square rock core is discharged by vent grooves 22 and the venting channels 19 of right rock core plug 6, and ventilation line 18 can access relevant apparatus as required.
As measured the rock core physical parameter of different directions, rock core is then needed to be fabricated to square, after testing a direction physical parameter one-tenth, operate following steps successively, close source of the gas, unload axial compression, unload confined pressure, unload lower cover 16, right rock core plug 6, left rock core plug 4, with strip article, rock core is taken out, rock core is rotated to measurement direction, repeating above-mentioned gripping step, the physical parameter carrying out other direction is measured.
