Then, the cutting test is performed on the rock sample through the cutting tool 2, so that after the rock sample is placed, the rock sample can be automatically fixed in advance during the movement of the cutting tool 2, so that the rock sample is more stable during the cutting test, which helps to make the final test data more accurate and improve the efficiency of the construction test of the drilling and anchoring machine.

One end of the torque sensor 14 away from the cutting tool 2 is fixedly connected to the output end of the first motor 17.

[0025] In the present invention, after the hydraulic cylinder 11 drives the movable plate 4 downward to approach the rock sample, the first motor 17 is started to drive the torque sensor 14 and the cutting tool 2 to rotate, so as to perform a cutting test on the fixed rock sample.

[0026] A plurality of three-axis force sensors 18 are fixedly installed on the cutting tool 2, a connecting plate 19 is fixedly connected to the bottom of the movable plate 4, a second motor 20 is fixedly installed on the connecting plate 19, a threaded rod 21 is fixedly connected to the output end of the second motor 20, the bearing plate 13, the support frame 15, and the mounting plate 16 are all threadedly connected to the threaded rod 21, a fixing plate 22 is fixedly connected to the bottom of the movable plate 4, a second guide rod 23 is fixedly connected to the fixing plate 22, and the bearing plate 13, the support frame 15, and the mounting plate 16 are all slidably connected to the second guide rod 23.

[0027] In the present invention, the load change of the cutting tool 2 can be recorded by the torque sensor 14, and the force change of the cutting tool 2 can be recorded by the three-axis force sensor 18 and the dynamic strain gauge. The torque sensor 14, the three-axis force sensor 18 and the dynamic strain gauge are all existing technologies; by starting the second motor 20 to drive the threaded rod 21 to rotate, under the action of the second guide rod 23, the lateral position of the cutting tool 2 can be controlled, and cutting tests at different lateral positions of the rock sample can be carried out.

[0028] Four telescopic guide rods 24 are fixedly connected to the top of the base 1 , a fixed platform 25 is fixedly connected to the top of the four telescopic guide rods 24 , the rock sample placement table 3 is fixedly connected to the fixed platform 25 , and a cylinder 26 is fixedly installed between the bottom of the fixed platform 25 and the base 1 .

[0029] In the present invention, the fixing platform 25 and the rock sample placing platform 3 can be driven to move up and down by starting the air cylinder 26 to adjust the position of the rock sample, and the fixing platform 25 is guided to slide by the four telescopic guide rods 24 .

[0030] The driving member 9 includes a plurality of first strip plates 901 fixedly connected to the bidirectional screw 6, a plurality of second strip plates 902 are hinged on the inner wall of the gear ring 8, a torsion spring 903 is fixedly connected between the second strip plates 902 and the inner wall of the gear ring 8, a plurality of baffles 904 for limiting the rotation of the second strip plates 902 are fixedly connected to the inner wall of the gear ring 8, a support limiting ring 905 is fixedly connected to one side of the rock sample placement table 3, a rotation groove is opened on one side of the gear ring 8, and the support limiting ring 905 is rotatably connected in the rotation groove of the gear ring 8.

[0031] In the present invention, while the driving rack 5 drives the gear ring 8 to rotate downward, the gear ring 8 drives the second strip plate 902 on its inner wall to rotate. The second strip plate 902, supported by the torsion spring 903 and the baffle 904, contacts the first strip plate 901, drives the first strip plate 901 and the bidirectional screw 6 to rotate, and then controls the two clamping plates 7 to approach each other to clamp the rock sample. When the rock sample with a thicker thickness is fixed, after the two clamping plates 7 clamp the rock sample, the hydraulic cylinder 11 drives the moving plate 4 to drive the cutting tool 2 to move to a suitable cutting position, and at this time the bidirectional screw 6 and the first strip plate 901 cannot Continue to rotate, at this time the gear ring 8 continues to drive the second strip plate 902 to rotate, at this time the second strip plate 902 can automatically compress and rotate toward the side with the torsion spring 903, and automatically disengage from the first strip plate 901, so that the bidirectional screw 6 will not continue to rotate, which can facilitate the hydraulic cylinder 11 to drive the cutting tool 2 to freely control the cutting depth of the rock sample, and facilitate the cutting of the rock sample layer by layer. Even if the cutting depth is deep, it will not affect the clamping force of the two clamps 7 on the rock sample, and at the same time it can also prevent the two clamps 7 from excessively clamping the rock sample; the gear ring 8 can be supported by the support limit ring 905.

[0032] Example 3: Reference Figure 1-Figure 10 , which is basically the same as the first embodiment, and further, one side of the base 1 and the stand 10 are fixedly connected with a mounting ear 27, and a rotating rod 28 is rotatably connected to the two mounting ears 27, and a spiral groove 29 is provided on the rotating rod 28, and a sliding rod 30 corresponding to the spiral groove 29 is fixedly connected to the movable plate 4 close to the rotating rod 28, and a vertical groove corresponding to the sliding rod 30 is provided on the stand 10, and a protrusion 31 is fixedly connected to the top of the rotating rod 28.

[0033] In the present invention, while the hydraulic cylinder 11 drives the movable plate 4 to move downward, it also drives the slide rod 30 to slide along the vertical groove of the stand 10 in the spiral groove 29 on the rotating rod 28, so that the rotating rod 28 continues to rotate, while driving the protrusion 31 at the top to rotate.

[0034] A connecting strip 32 is fixedly connected to the stand 10, a gas collecting barrel 33 is fixedly connected to the connecting strip 32, a piston plate 34 is slidably connected inside the gas collecting barrel 33, a push rod 35 is fixedly connected to the piston plate 34, the push rod 35 is slidably connected to the gas collecting barrel 33, and a spring 36 is sleeved on the push rod 35.

[0035] In the present invention, the spring 36 can make the push rod 35 automatically reset after entering the gas collecting barrel 33 .

[0036] The two ends of the spring 36 are fixedly connected to the push rod 35 and the air collecting barrel 33 respectively. The end of the push rod 35 away from the piston plate 34 abuts against the protrusion 31. The interior of the air collecting barrel 33 is divided into a first chamber 3301 and a second chamber 3302 by the piston plate 34. The first chamber 3301 is fixedly connected with an intake pipe 37 and an exhaust hose 38 respectively. The end of the exhaust hose 38 away from the first chamber 3301 is fixedly installed with a connected jet plate 39.

[0037] In the present invention, while the convex block 31 is continuously rotating, when the protruding portion of the convex block 31 contacts the push rod 35, the push rod 35 is driven to drive the piston plate 34 to slide toward the inner direction of the gas collecting barrel 33, and the outside air is sucked into the first chamber 3301 through the suction pipe 37 for collection. Then, when the convex portion of the convex block 31 does not contact the push rod 35, the push rod 35 automatically drives the piston plate 34 to reset through the spring 36, compresses the gas in the first chamber 3301, squeezes the gas out through the gas outlet hose 38, and finally sprays the gas through the jet plate 39, and so on. When the moving plate 4 drives the cutting tool 2 downward, the jet plate 39 sprays the dust particles on the surface of the rock sample from top to bottom, so that the dust and other particles on the surface of the rock sample are removed in advance before the two clamping plates 7 are clamped, so that the rock sample clamping effect is improved. The result is more stable, which promotes the rock sample to be more stable during the cutting test process, and the data obtained is more accurate. Compared with the traditional method of using a sealed fan and other uniform wind force, the jet plate 39 can gradually increase the wind force of the ejected gas on the rock sample placement table 3 and the surface of the rock sample from top to bottom, and the effect is better; it should be noted that a one-way valve is installed inside the intake pipe 37 and the air outlet hose 38, the purpose is to prevent the air from being sucked in from the jet plate 39 when the first chamber 3301 is inhaled, and to prevent the air from being ejected from the intake pipe 37 when the gas is ejected; at the same time, when the hydraulic cylinder 11 drives the moving plate 4 to drive the slide bar 30 to reset, the rotating rod 28 will also drive the protrusion 31 to rotate, so that the air outlet hose 38 can automatically clean up the dust and debris generated by cutting on the rock sample placement table 3, which is convenient for the staff to collect rock fragments and save the measured data later.

[0038] The second chamber 3302 is fixedly connected with a water suction pipe 40 and a water outlet pipe 41, respectively. One end of the water outlet pipe 41 away from the second chamber 3302 is fixedly connected with a spray plate 42. A mounting seat 43 is fixedly connected to the base 1, and a water bucket 44 is placed on the mounting seat 43. One end of the water suction pipe 40 away from the second chamber 3302 is connected with the water bucket 44.

[0039] In the present invention, when the piston plate 34 repeatedly collects air in the first chamber 3301, the second chamber 3302 will repeatedly inhale water from the water bucket 44 through the water suction pipe 40, and then squeeze it out from the water outlet pipe 41, and spray mist water through the spray plate 42, so as to perform dust reduction operation on the dust raised by the jet plate 39 above the rock sample. During the cutting process, the water mist sprayed by the spray plate 42 falls on the rock sample, and can also reduce the sparks and dust generated by the cutting between the cutting tool 2 and the rock sample, and reduce the fluttering of dust. During the process of the hydraulic cylinder 11 driving the moving plate 4 and the cutting tool 2 to reset upward, the water suction pipe 40 and the water bucket 44 can be disassembled, and the spray plate 42 can be used to spray air to cooperate with the jet plate 39 to remove dust from the rock sample placement table 3 and the surface of the rock sample. It should be noted that a one-way valve is installed inside the water suction pipe 40 and the water outlet pipe 41, so as to prevent water from being sprayed out from the water suction pipe 40 when the water outlet pipe 41 sprays water.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
