Embodiment 1
[0036] Present embodiment 1 provides a kind of rock strength testing device, such as figure 1 As shown, the rock strength testing device includes: a base 12, a beam 1 and two columns 5;
[0037] The two columns 5 are vertically fixed on the base 12; the beam 1 is vertically connected to the two columns 5 .
[0038] The support structure is formed by connecting the base 12 , the beam 1 and the two columns 5 .
[0039] The base 12 is also provided with a pressure applying device 4, on which the pressure applying device 4 is provided with a lower pressure contact 3, and the lower pressure contact 3 points to the beam 1;
[0040] At least one upper pressure contact 2 is movably connected to the beam 1 , and the upper pressure contact 2 points to the base 12 .
[0041] There are many ways in which the upper pressure contact 2 is movably connected to the crossbeam 1. For example, a plurality of screw holes are set on the crossbeam 1, and threads matched with the screw holes are se...
Embodiment 2
[0044] Present embodiment 2 provides a kind of rock strength testing device on the basis of embodiment 1, as figure 2 and image 3 As shown, the rock strength testing device includes a base 12 , a beam 1 and two columns 5 .
[0045] The two columns 5 are vertically fixed on the base 12; the beam 1 is vertically connected to the two columns 5;
[0046] Wherein, the crossbeam 1 is vertically connected with the two columns 5, including: the crossbeam 1 is vertically movably connected with the two columns 5 through the limit bolt 11, and the position of the crossbeam 1 on the column 5 can be adjusted by the limit bolt 11, It is beneficial to adapt to the shape and size of the rock sample 9 to be tested, so that the rock strength testing device can test rock samples 9 of different shapes and sizes.
[0047] In addition, the connection of the base 12 , the beam 1 and the two uprights 5 forms a support structure, and the formed support structure mainly functions as support and fix...

Abstract
The invention relates to the technical field of experimental apparatuses, especially to a rock strength testing device. The rock strength testing device comprises a base, a crossbeam and two columns, wherein the two columns are vertically fixed on the base, the crossbeam is vertically connected with the two columns, the base is provided with a pressure applying unit, a lower pressure contact is arranged on the pressure applying unit and points to the crossbeam, and the crossbeam is movably connected with at least one upper pressure contact which points to the base. The rock strength testing device provided by the invention can realize rock mechanical strength test of a rock sample on a coring site in a plurality of modes.
Description
technical field [0001] The invention relates to the technical field of experimental devices, in particular to a rock strength testing device. Background technique [0002] At the drilling and coring site, it is necessary to perform a mechanical strength test on the collected rock samples. [0003] In the related art, at the coring site, a point load meter is used to perform an on-site mechanical strength test on the collected rock samples. When performing a mechanical strength test on rock samples at the coring site, the point-to-point mechanical strength test is mainly performed through an upper pressure contact fixedly connected to the point load instrument, a lower pressure contact opposite to the upper pressure contact, and a pressure applying device. . [0004] However, the point load instrument can only perform on-site point-to-point rock mechanical strength tests on rock samples, and the test method is relatively simple. Contents of the invention [0005] The pre...
