Description

Technical Field

[0001] This utility model relates to the technical field of geotechnical testing devices, specifically geotechnical testing devices for engineering research. Background Technology

[0002] Geotechnical testing refers to all kinds of tests conducted on rocks and soil for the purpose of engineering construction. Geotechnical testing is an important component of engineering geological exploration. It is divided into sampling tests that detach rock and soil samples from the parent material and in-situ tests conducted directly on the rock and soil mass. In-situ rock mass tests include three aspects: deformation tests, strength tests, and in-situ stress tests. Strength tests mainly involve direct shear and compressive strength tests of the rock mass. Compressive strength tests are often combined with deformation tests using the bearing plate method. During the strength test, the rock and soil are continuously pressurized until they break to obtain strength data. After the rock and soil break into fragments, they remain on the placement platform. Traditionally, the operator uses a scraper to remove the fragments from the placement platform and then uses a brush to sweep away the fine debris. Although this method achieves the purpose of cleaning, it is time-consuming and labor-intensive, especially in large-scale geotechnical tests. After each test, manual cleaning is required before the next test, which greatly reduces the efficiency of the test. At the same time, when conducting direct shear and compressive strength tests of the rock mass, different test heads need to be changed. The traditional installation method is threaded installation, which is cumbersome to change and has poor practicality. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] This application provides a geotechnical testing device for engineering research. This geotechnical testing device can clean the placement platform through a cleaning component, eliminating the need for manual cleaning, thus saving time and effort. After each test, the rotating plate and brush that sweep back and forth clean up the fragments and fine debris for the next test, shortening the cleaning waiting time and improving the testing efficiency.

[0024] The following provides a detailed description of the geotechnical testing apparatus used in this engineering research. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] Please see Figures 1-7 This embodiment provides a geotechnical testing device for engineering research, comprising: a processing table 1, a box 11 on top of the processing table 1, a base plate 12 fixedly connected to the top of the processing table 1, a hydraulic rod 13 fixedly installed on the top of the box 11, the bottom end of the hydraulic rod 13 penetrating the box 11 and fixedly connected to a connecting block 14, a pressure block 15 at the bottom of the connecting block 14, and a placement platform 16 fixedly connected to the base plate 12; a cleaning assembly, located inside the box 11, for cleaning debris on the placement platform 16, the cleaning assembly including: a guide rod 2, a base 21, a torsion cylinder 22, a rotating plate 23, and a brush 24; and a disassembly assembly, located on the connecting block 14, for facilitating the replacement of the pressure block 15, the disassembly assembly including: a slot 3, a storage slot 31, a locking block 32, a connecting rod 33, a spring 34, and a handle 35.

[0028] In use, open the door of the housing 11, place the soil and rock on the placement platform 16, close the door, and then activate the hydraulic rod 13 to push it downwards. This causes the hydraulic rod 13 to push the connecting block 14 and the pressure block 15 downwards, thereby compressing the soil and rock to test its strength. The gauge on the hydraulic rod 13 can display the maximum pressure. After the test is completed, the hydraulic rod 13 retracts, and the cleaning component cleans the placement platform 16, sweeping the soil and rock off the platform 16, thus eliminating the need for manual cleaning. Furthermore, the pressure block 15 can be replaced by disassembling the assembly, allowing the use of different types of pressure blocks 15 to test the soil and rock.

[0029] Example 2

[0030] Based on Embodiment 1, a guide rod 2 is rotatably connected between the base plate 12 and the housing 11. A base 21 is provided near the bottom of the guide rod 2, and the bottom of the base 21 is connected to the base plate 12. A torsion cylinder 22 is fixedly installed on the outside of the guide rod 2, and the torsion cylinder 22 is located on the top of the base 21. A rotating plate 23 is fixedly connected to the periphery of the torsion cylinder 22, and a brush 24 is provided at the bottom of the rotating plate 23. The top end of the guide rod 2 extends through the housing 11 to the outside and is fixedly connected to a cam a 25. A drive motor 26 is fixedly installed at the top inside the housing 11. The drive shaft at the top of the drive motor 26 passes through the housing 11 and extends to the outside and is fixedly connected to the cam b27. The cam a25 cooperates with the cam b27. The top of the base 21 has a placement groove 28, and the placement groove 28 has a spring 29 inside. The inner wall of the torsion cylinder 22 is rotatably connected to the rotating cylinder 210. The top of the rotating cylinder 210 is connected to the bottom of the torsion cylinder 22. The outermost end of the spring 29 is connected to the inner wall of the rotating cylinder 210, and the innermost end of the spring 29 is connected to the inner wall of the rotating cylinder 210.

[0031] After the soil and rock test is completed, the soil and rock fragments break apart. When it is necessary to clean up the soil and rock debris on the placement platform 16, the drive motor 26 is started to drive the cam b27 to rotate. When the cam b27 rotates, its protruding part contacts the protruding part of the cam a25, pushing the cam a25 to rotate. The cam a25 drives the guide rod 2 to rotate, and the guide rod 2 drives the torsion cylinder 22 to rotate. When the torsion cylinder 22 rotates, it drives the bottom rotating cylinder 210 to rotate in the placement groove 28. When the rotating cylinder 210 rotates, it drives the outermost end of the spring 29 to rotate, causing the spring 29 to contract and store energy. When the cam b27 rotates... When the protruding part of the rotating cylinder 210 separates from the protruding part of the cam a25, the spring spring 29 releases its elasticity and drives the rotating cylinder 210 to rotate in the opposite direction. The rotating cylinder 210 drives the torsion cylinder 22 and the guide rod 2 to rotate in the opposite direction and return to the initial position. This causes the torsion cylinder 22 to rotate repeatedly. When the torsion cylinder 22 rotates, it drives the rotating plate 23 and the brush 24 to rotate. The rotating plate 23 and the brush 24 sweep back and forth across the placement table 16. The rotating plate 23 pushes down large pieces of debris, and the brush 24 sweeps down the debris. After cleaning, the box 11 is opened to continue the next inspection operation.

[0032] The processing table 1 is fixedly connected to a support frame 4, and a collection box 41 is slidably connected inside the support frame 4. Two symmetrically arranged feeding slots 42 are opened on the processing table 1 and the base plate 12 respectively, and the bottom of the two feeding slots 42 are connected to the support frame 4.

[0033] The cleared rock and soil fragments and debris fall into the two discharge troughs 42, enter the support frame 4 along the discharge troughs 42, and finally fall into the collection box 41. The collection box 41 can be pulled out from the support frame 4 to facilitate the cleaning of the objects in the collection box 41.

[0034] Example 3

[0035] Based on embodiment 1, the bottom of the connecting block 14 is provided with a slot 3, and the inner walls of the slot 3 on both sides are respectively provided with storage grooves 31. The two storage grooves 31 are respectively provided with two locking blocks 32. The opposite sides of the two locking blocks 32 are respectively fixedly connected to connecting rods 33. The two connecting rods 33 are each fitted with a spring 34. The opposite ends of the two connecting rods 33 pass through the two connecting blocks 14 and extend to the outside and are fixedly connected to handles 35. The top of the pressure block 15 is fixedly connected with a T-shaped insertion block 36. The top two ends of the insertion block 36 are relatively inclined. The two locking blocks 32 are symmetrically arranged and the opposite corners of their bottoms are respectively inclined to both sides.

[0036] When it is necessary to replace the cone, cutter, or other shaped pressure block 15, pull the two handles 35 to the sides. The connecting rod 33 will then pull the two locking blocks 32 into the two receiving slots 31, causing the locking blocks 32 to move away from the sides of the T-shaped insertion block 36. As the locking blocks 32 move, they will compress the spring 34, causing the spring 34 to contract and store energy, thus releasing the fixing of the insertion block 36. Under the action of gravity, the pressure block 15 will move the insertion block 36 out of the slot 3. Then, release the two handles 35. Under the action of the spring 34, the locking blocks 32 will be pushed back to their initial position. Finally, the top of the pressure block 15 of the desired shape will be placed... The plug block 36 is inserted into the slot 3. The two inclined edges of the top of the T-shaped plug block 36 fit against the inclined surfaces of the bottom of the two locking blocks 32. As the plug block 36 is pushed upward, the inclined surfaces of the two locking blocks 32 move along the inclined surfaces of the top of the plug block 36 and separate to both sides. The two locking blocks 32 move to compress the spring 34. When the plug block 36 is inserted into place, the top of the plug block 36 is offset from the two locking blocks 32. Under the action of the spring 34, the two locking blocks 32 are pushed to move relative to each other and move to the right angle on both sides of the plug block 36, thereby fixing the plug block 36 in place, thus completing the replacement of the pressure block 15.
