When using described rock pressure proving installation, carry out the test of rock specimens 9 mechanical strengths getting the core scene, can realize different mechanical strength tests by the quantity that upward pressure contact 2 is set.
As shown in Figure 2, being connected with 2, two upward pressure contacts 2 of two upward pressure contacts by bolt 8 on the saturating groove 7 of crossbeam 1 is the center with downforce contact 3, is symmetrically distributed in the both sides of downforce contact 3.
For the ease of regulating the position of upward pressure contact 2, along the length direction of crossbeam 1, on crossbeam 1, be fixedly connected with scale, help the position of upward pressure contact 2 is regulated by the scale that is provided with.
The described rock strength proving installation that use is provided with two upward pressure contacts 2 can carry out the three-point bending strength test to rock specimens 9, when carrying out the three-point bending strength test, rock specimens 9 is interposed between two upward pressure contacts 2 and the downforce contact 3, exert pressure until rock specimens 9 is destroyed by the 4 pairs of downforce contacts 3 of device for exerting that are arranged on the pedestal 12, and when record rock specimens 9 is destroyed, 4 pairs of downforce contact 3 applied pressures of device for exerting.
In addition, for the ease of rock specimens 9 is interposed between two upward pressure contacts 2 and the downforce contact 3, and also more firm for rock specimens 9 being inserted and put ground, all be connected with an auxiliary support plate 6 on each column 5; Auxiliary support plate 6 is between crossbeam 1 and pedestal 12.
Particularly, auxiliary support plate 6 all can be movably connected on the column 5 by caging bolt 11, and corresponding adjusting can be carried out in its position on column 5.
When carrying out the test of rock strength three-point bending strength, two auxiliary support plates 6 are oppositely arranged, and for rock specimens 9 provides corresponding support and set-point, be convenient to the placement of rock specimens 9, and can be by two upward pressure contacts 2 and downforce contact 3, more firm with rock specimens 9 clampings guarantees that the related data that tests out is more accurate.
After using the rock strength proving installation, measuring relevant mechanical strength data, the computing that also needs to utilize the data that obtain to be correlated with.
Though the device for exerting 4 that utilization is arranged on the pedestal 12 can read the data of exerting pressure, for example device for exerting 4 is a hydraulic jack, can directly read the pressure of exerting pressure by hydraulic jack what are; But the described data of exerting pressure that read also need manually to carry out record, and are input in the corresponding data processing equipment, carry out the processing of data.
For the ease of the data of exerting pressure that obtain being write down and utilizing the described data of exerting pressure to carry out data processing, a data transducer 10 is set between the projecting shaft of downforce contact 3 and device for exerting 4, can respond to by data transducer 10 and to obtain device for exerting 4 applied pressure data, and data transducer 10 is connected with data processing equipment by the data acquisition line, is transferred to record and the relevant data processing that data processing equipment carries out pressure data with the pressure data that will gather.
For example, described data transducer 10 is a piezoelectric pressure indicator.
The rock strength proving installation of present embodiment has multiple function, not only can carry out 3 mechanical strength tests to rock specimens 9, but also can carry out point-to-point mechanical strength test to the rock specimens of gathering 9.
For the rock specimens of gathering 9 being carried out point-to-point mechanical strength test, as shown in Figure 3, on the saturating groove 7 of crossbeam 1, connect a upward pressure contact 2, the dead in line of the axis of upward pressure contact 2 and described downforce contact 3 by bolt 8.By cooperating of upward pressure contact 2 and downforce contact 3, insert and put rock specimens 9, exert pressure by device for exerting 4 and destroy rock specimens 9, and the record related data of testing, and carry out data processing by data processing equipment and get final product.
In the prior art, can only carry out point-to-point mechanical strength test to the rock specimens of gathering 9 getting the core scene, directly measure the applied pressure data, obtain supplemental characteristic by the applied pressure data are carried out relevant treatment.
But, only carry out the rock mechanics strength test with a kind of mode, even carry out independently testing experiment repeatedly, therefore the formula that the pressure data that at every turn obtains is calculated is identical, can't judge whether the supplemental characteristic that draws is accurate, therefore need to adopt other test mode that supplemental characteristic is verified.
And the rock strength proving installation of present embodiment, both can carry out point-to-point mechanical strength test and three-point bending strength test to rock specimens 9, operational method by two kinds of test modes and two kinds of test mode correspondences, can obtain test figure respectively about same parameter, for example tensile strength judges by comparison whether the supplemental characteristic that obtains is accurate.
And the rock strength proving installation of present embodiment, mainly flexibly connect by bolt 8, caging bolt 11, be convenient to assemble, dismantle transportation and the use of so being convenient to the mechanical strength test unit.
The various embodiment that the utility model provides can be as required combination mutually in any way, the technical scheme that obtains by this combination is also in scope of the present utility model.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also comprises these changes and modification interior.
