[0002] The strength of rock and soil needs to be tested in geological surveys. Rock and soil strength testing is a key link in engineering geological surveys. It provides important data support for civil engineering, geological engineering, mining engineering and other fields. When the existing geological and geotechnical testing equipment tests rock and soil, it first samples the rock and soil, then applies a unidirectional compression load to the sampled rock and soil to measure the compressive strength and deformation characteristics of the rock. However, when a unidirectional compression load is applied to the rock and soil sample, the rock and soil sample loses the squeezing force of the surrounding rock and soil. The rock and soil sample may have deteriorated or cracked. If a unidirectional compression load is applied again, the measured compressive strength and deformation characteristics of the rock are not accurate. Summary of the invention

[0022] The clamping assembly includes two vertical plates 1, which are arranged in parallel. A first vertical guide groove 11 is provided on one side of each vertical plate 1. A first slider 12 is slidably connected in each first vertical guide groove 11. The first slider 12 is an "I"-shaped slider, which can ensure that the first slider 12 slides back and forth up and down in the first vertical guide groove 11 without falling off. One side of the first slider 12 is slidably connected to a first slide rod 14, and a first clamping plate 16 is installed at one end of the first slide rod 14. A first electric telescopic rod 15 is installed on one side of the first slider 12. The first electric telescopic rod 15 is used to drive the first slide rod 14 to reciprocate horizontally. A first electric lifting rod 13 is installed in the first vertical guide groove 11. The first electric lifting rod 13 is used to drive the first slider 12 to reciprocate up and down. A second vertical guide groove 17 is provided on one side of each vertical plate 1, and a second slider 18 is slidably connected in each second vertical guide groove 17. The second slider 18 is an "I"-shaped slider, which can ensure that the second slider 18 slides back and forth up and down in the second vertical guide groove 17 without falling off. One side of the second slider 18 is slidably connected to the second slide bar 110, and a second clamping plate 112 is installed at one end of the second slide bar 110. A second electric telescopic rod 111 is installed on one side of the second slider 18. The second electric telescopic rod 111 is used to drive the second slide bar 110 to reciprocate horizontally. A second electric lifting rod 19 is installed in the second vertical guide groove 17, and the second electric lifting rod 19 is used to drive the second slider 18 to reciprocate up and down.

[0023] The clamping assembly is used to clamp the sampling barrel 2, which contains rock and soil samples. The sampling barrel 2 includes a barrel bottom plate 23, on which a plurality of barrel wall rings 20 are stacked and arranged. The barrel wall rings 20 are tightened and fixed by threaded tie rods 21. The barrel wall rings 20 are provided with threaded holes with corresponding meanings. The threaded tie rods 21 pass through the threaded holes in sequence, so that the barrel wall rings 20 are stacked and arranged as a whole. The threaded tie rods 21 are threadedly connected with locking nuts 22, and the barrel wall rings 20 are locked and fixed by the locking nuts 22. When separating the barrel wall rings 20, the threaded tie rods 21 are rotated to separate the barrel wall rings 20 at the bottom.

[0024] The test assembly includes a slide plate 32, which slides back and forth in a slider on one side of a base plate 31. A cylinder 34 is installed on one side of the base plate 31. The cylinder 34 is used to drive the slide plate 32 to move back and forth horizontally. One side of the slide plate 32 is fixedly connected to a mounting plate 41. A strength tester 5 is installed on the mounting plate 41. The strength tester 5 is a hydraulic cylinder. This is a prior art and will not be described in detail here. One side of the mounting plate 41 is fixedly connected to two cross bars 40. An electric cutting saw 43 is installed between the two cross bars 40. The electric cutting saw 43 is a prior art and will not be described in detail here.

[0025] During use, the first clamping plate 16 is pushed by the first electric telescopic rod 15 to clamp the sampling barrel 2, and the rock sample in the sampling barrel 2 is located above the supporting plate 6. At this time, the lowest barrel wall ring 20 is released, and the second clamping plate 112 is pushed by the second electric telescopic rod 111 to clamp the lowest barrel wall ring 20. At the same time, the second sliding block 18 is driven downward by the second electric lifting rod 19. At this time, the second clamping plate 112 and the barrel wall ring 20 move downward at the same time, so that there is a gap between the barrel wall rings 20, and the sliding plate 32 is driven forward by the cylinder 34 to slide. During the advancement of the plate 32, the rock sample is cut into pieces by the electric cutting saw 43. After the cutting is completed, the first electric lifting rod 13 drives the first slide block 12 to move upward. As the slide plate 32 continues to move forward, when the strength tester 5 is located above the cut rock sample, the rock sample is tested by the strength tester 5. At this time, the rock sample is still in the barrel wall ring 20. In this way, during the test, the barrel wall ring 20 has a wrapping force on the rock sample, which simulates the rock being wrapped in a large piece of rock, and improves the accuracy during the test. In the above manner, the rock sample can be cut into multiple pieces, so that the sample can be tested, and the strength of the rock sample at different positions can be tested.

[0026] In order to prevent the upper end of the rock sample from falling out of the sampling bucket after cutting, a placement groove 47 is provided on the crossbar 40, in which a fixed beam 46 is placed, and a flat plate 45 is installed on the fixed beam 46, and a suspension rod 48 is fixedly connected to the fixed beam 46, and a plug hole is provided on one side of the suspension rod 48, and an "L"-shaped bracket 9 is fixedly connected to one side of the first slider 12, and an insertion rod 91 is fixedly connected to one side of the bracket 9. When the slide plate 32 continues to move forward, the insertion rod 91 can be inserted into the insertion hole, and when the sampling bucket rises with the first slider, the "L"-shaped bracket 9 drives the fixed beam 46 and the flat plate 45 to rise, so that the rock sample is supported from the bottom through the flat plate 45, so that the rock sample will not fall out of the sampling bucket.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
