Abstract
An auxiliary device for dismounting a confining pressure loading test piece comprises an upper bearing plate, a lower bearing plate and an extruding screw rod used for extruding the test piece out of a confining pressure loading device. A through hole allowing the extruding screw rod to pass is formed in the center of the upper bearing plate, a through hole allowing the test piece to be extruded out is formed in the center of the lower bearing plate, the upper bearing plate is parallel to the lower bearing plate, the upper bearing plate and the lower bearing plate are connected to form an integrated structure through at least two stand columns, and limiting clamping tables used for fixing the lower bearing plate and locking nut sets used for fixing the upper bearing plate and the lower bearing plate respectively are arranged on the stand columns. Due to the fact that the extruding screw rod in the auxiliary device can provide continuous and stable extruding force, the test piece is gradually extruded out of the confining pressure loading device, the integrity of the test piece can be kept, testing of the mechanical property of time after dismounting of the test piece is not influenced, and the sealing performance of the confining pressure loading device is not damaged. The auxiliary device has the advantages of being flexible, convenient to use and easy to assemble and disassemble.
Description
Technical field
The utility model relates in three axle Rock Mechanics Test Ands the removal of test specimen, specifically a kind of servicing unit for removal confined pressure loading specimen under confined pressure effect.
Background technology
In rock mechanics, often adopt confined pressure charger simulation deep mechanical environment, the mechanical property of test deep rock.Common way is, test specimen, with putting into hydraulic jack after rubber sleeve parcel, is added to hydraulic oil by hydraulic hand-pump in oil cylinder, in the time that hydraulic pressure reaches required confined pressure value, closes oil-in, by oil pressure, test specimen applied the Load Simulation confined pressure power of hoop.But, after having tested, press the removal that breaks the bad transversely deforming producing and limited test specimen, in detach procedure, easily cause the damage of oil pressure water-tight equipment.And, Practical Project as underground excavation or mining process in, along with the increase of construction depth, rock mass continues in unloaded state, and general experiment is carried out simple confined pressure loading experiment to sample, after unloading, test specimen suffers damage and failure, is difficult to the mechanical characteristic of the rear test specimen of test unloading.Therefore, develop a set of can complete removal test specimen, and the device that does not destroy oil pressure water-tight equipment is very necessary.
Utility model content
The purpose of this utility model is to overcome the damage that easily causes oil pressure water-tight equipment in prior art in detach procedure, and after removal, test specimen is destroyed, cause the problem that is difficult to test the mechanical characteristic after its unloading, a kind of servicing unit for removal confined pressure loading specimen is provided.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of servicing unit for removal confined pressure loading specimen, comprise upper supporting disk, for placing the lower carrier of confined pressure charger and the extruding screw for test specimen is extruded from confined pressure charger, be provided with the through hole passing through for extruding screw in the center of upper supporting disk, the center of lower carrier is provided with the through hole extruding for test specimen, described upper supporting disk and lower carrier are parallel to each other, and upper supporting disk is connected and is integrative-structure by least two root posts with lower carrier, described column is provided with the limiting card platform for fixing lower carrier, and the locking nut group of fixing respectively upper supporting disk and lower carrier.
The corresponding through hole passing through for column that is evenly equipped with on described upper supporting disk and lower carrier.
The height of the column of described lower carrier below is greater than the height of test specimen.
Beneficial effect: (1), because the extruding screw in this device can provide lasting, stable extruding force, test specimen is extruded gradually from confined pressure charger, can keep the integrality of test specimen, not affect the mechanical characteristic of the time after test removal, and not destroy the sealing property of confined pressure charger;
(2), in this device, upper supporting disk and lower carrier are fixed on column by locking nut group, can adjust the spacing between upper supporting disk and lower carrier according to the actual height for the treatment of removal test specimen in when experiment, this device has the feature of flexibility, easy to use and easy assembly and disassembly.
