Description

Technical Field

[0001] This utility model relates to the field of triaxial compression test technology, specifically to a leak-proof and stabilizing device based on triaxial compression test. Background Technology

[0002] The core of triaxial compression testing lies in applying axial pressure to the test specimen through vertical movement. By gradually increasing the axial pressure, the stress state inside the specimen changes during this process, especially the stress difference generated in the vertical direction. This allows for a direct understanding of the mechanical response of the specimen under different confining pressures. Further analysis yields key mechanical parameters such as the shear strength, internal friction angle, and cohesion of the material, providing important basis for engineering design and material selection.

[0003] When the specimen is placed in the connecting seat of the triaxial compression test, due to factors such as machining accuracy, assembly error, or thermal expansion and contraction of materials, it is often difficult to achieve a complete fit between the specimen and the connecting seat, thus forming tiny gaps. During the experiment, oil in the pressure chamber can easily seep into these gaps. The wetting of oil not only changes the contact state between the specimen and the connecting seat, but may also affect the mechanical properties of the specimen, thereby affecting the stress state inside the specimen, which has certain defects.

[0007] The first clamping assembly is located on the outside of the first experimental connector and is used to fasten the connection between the first experimental connector and the experimental specimen to prevent oil from entering the first experimental connector from the connection gap between the first experimental connector and the experimental specimen.

[0009] A stabilizing element is disposed between the first clamping assembly and the second clamping assembly to ensure that the first clamping assembly and the second clamping assembly are always in a horizontal state.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the first clamping assembly includes:

[0012] A first annular connector is disposed on the outside of the first experimental connector, wherein both ends of the first annular connector are provided with a first notch;

[0013] A connector is disposed within one of the first notches of the first annular connector;

[0014] The second annular connector has a second notch at both ends, and the other end of the connector is located in one of the second notches of the second annular connector. The second annular connector is rotatably connected to the first annular connector through the connector.

[0015] A locking member is disposed on the first annular connector and interconnected with the second annular connector. The locking member is used to press the first annular connector and the second annular connector against the outside of the first experimental connector.

[0016] Furthermore, the locking member includes:

[0017] The shaft is fixedly installed on the inside of another notch in the first annular connector;

[0018] The screw is sleeved on the outside of the shaft, wherein the shaft can rotate with the shaft as the origin to the inside of another second notch of the second annular connector;

[0019] The first hand-tightened nut is threaded onto the outside of the screw, and one side surface of the first hand-tightened nut is in contact with the surface of the second annular connector.

[0020] Furthermore, both the first annular connector and the second annular connector have concave notches on the side surfaces near the first experimental connector that are adapted to the outer wall of the first experimental connector.

[0021] Furthermore, the second clamping assembly includes:

[0022] The first clamping element is located on the outside of the second experimental connecting seat;

[0023] The second clamping member is disposed on the outside of the second experimental connecting seat, wherein the first clamping member and the second clamping member are combined together and closely attached to the outside of the second experimental connecting seat;

[0024] A connecting bolt passes through the first clamping member and connects to the second clamping member, wherein the first clamping member and the second clamping member can be connected together by the connecting bolt.

[0025] Furthermore, both the first clamping member and the second clamping member have arc-shaped notches on the side surfaces near the second experimental connecting seat that are adapted to the outer wall of the second experimental connecting seat. There are two connecting bolts, which are respectively set on the two ends of the first clamping member and the second clamping member.

[0031] This invention introduces a first clamping component and a second clamping component, respectively disposed on the outer sides of the first and second experimental connecting seats, to effectively fasten the experimental specimen to the connection point of the connecting seat. This design not only enhances the contact pressure between the specimen and the connecting seat, maximizing the compression of the gap, but also effectively prevents the gap from widening due to pressure changes or thermal expansion and contraction of materials during the experiment through the locking function of the clamping components. This effectively prevents oil from seeping into the connecting seat from the connection gap. Secondly, a stabilizing component is disposed between the first and second clamping components, and its key function is to maintain the horizontal state between the clamping components. This not only helps maintain the stability of the specimen during the experiment and prevents uneven stress on the specimen caused by loosening or deformation of the clamping components, but also further enhances the rigidity and stability of the entire device. Through the constraint of the stabilizing component, the clamping components can better perform their fastening function, further improving the anti-leakage effect. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Combination Figures 1-5 As shown, this utility model discloses a leak-proof and stabilizing device based on a triaxial compression test, comprising a first experimental connecting seat 1 and a second experimental connecting seat 2 for the triaxial compression test, wherein an experimental specimen 3 is disposed between the first experimental connecting seat 1 and the second experimental connecting seat 2, and further comprising:

[0040] The first clamping component 4 is disposed on the outside of the first experimental connecting seat 1. It is used to fasten the connection between the first experimental connecting seat 1 and the experimental specimen 3 to prevent oil from entering the first experimental connecting seat 1 from the connection gap between the first experimental connecting seat 1 and the experimental specimen 3.

[0041] The second clamping component 5 is located on the outside of the second experimental connecting seat 2. It is used to fasten the connection between the second experimental connecting seat 2 and the experimental specimen 3 to prevent oil from entering the second experimental connecting seat 2 from the connection gap between the second experimental connecting seat 2 and the experimental specimen 3.

[0042] The stabilizing member 6 is disposed between the first clamping assembly 4 and the second clamping assembly 5, and is used to ensure that the first clamping assembly 4 and the second clamping assembly 5 are always in a horizontal state.

[0043] During the triaxial compression test, the test specimen 3 was placed between the first test connector 1 and the second test connector 2 to simulate the stress state in actual engineering. To effectively prevent oil leakage from the gap between the specimen and the first test connector 1 and the second test connector 2, a first clamping assembly 4 and a second clamping assembly 5 were designed. The first clamping assembly 4 is located on the outside of the first test connector 1. Through its clamping action, it can firmly clamp the connection between the test specimen and the first test connector 1, thereby preventing oil from seeping into the interior of the first test connector 1 from the connection gap. Similarly, the second clamping assembly 5 is located on the outside of the second test connector 2. On the side, it also serves the same function of fastening and preventing leakage. In addition, in order to ensure the stability of the specimen and the relative position between the first clamping component 4 and the second clamping component 5 during the experiment, a stabilizing component 6 is introduced. The stabilizing component 6 is set between the first clamping component 4 and the second clamping component 5, which can limit the first clamping component 4 and the second clamping component 5 to always be in a horizontal state. This design not only helps to maintain the uniformity of the force on the specimen during the experiment, but also further enhances the rigidity and stability of the entire device, thereby improving the leakage prevention effect. It should also be noted that the fixed dimensions of the specimen are 100mm in height and 50mm in diameter.

[0044] In a preferred embodiment, this utility model can be further configured as follows: Figure 2 , Figure 3 As shown; the first clamping assembly 4 includes:

[0045] The first annular connector 41 is disposed on the outside of the first experimental connector 1, wherein the two ends of the first annular connector 41 are provided with a first notch;

[0046] The connector 42 is disposed within one of the first notches of the first annular connector 41;

[0047] The second annular connector 43 has a second notch at both ends. The other end of the connector 42 is located in one of the second notches of the second annular connector 43. The second annular connector 43 is rotatably connected to the first annular connector 41 through the connector 42.

[0048] A locking member 44 is disposed on the first annular connector 41 and interconnected with the second annular connector 43. The locking member 44 is used to press the first annular connector 41 and the second annular connector 43 to the outside of the first experimental connecting seat 1. The first annular connector 41 is disposed on the outside of the first experimental connecting seat 1, and both ends of its first annular connector 41 are designed with first notches. These notches provide installation space for the subsequent connector 42. Then, one end of the connector 42 is placed in one of the first notches of the first annular connector 41, realizing a preliminary connection. Then, the introduction of the second annular connector 43 further enhances the clamping effect. Both ends of the second annular connector 43 are also provided with second notches, while the other end of the connector 42 is... The first annular connector 41 and the second annular connector 43 are located in one of the second notches of the second annular connector 43. Through this design, the first annular connector 41 and the second annular connector 43 can be rotated to each other through the connector 42. This not only provides installation flexibility, but also ensures that the clamping assembly is evenly stressed during the tightening process. Finally, the locking member 44 is installed on the first annular connector 41 and connected to the second annular connector 43. When tightening is required, the locking member 44 plays a role in pressing the first annular connector 41 and the second annular connector 43 tightly to the outside of the first experimental connecting seat 1, thereby effectively sealing the gap between the experimental specimen 3 and the first experimental connecting seat 1 and preventing oil leakage.

[0049] In a preferred embodiment, this utility model can be further configured as follows: Figure 2 , Figure 3 As shown; the locking component 44 includes:

[0050] Shaft 441 is fixedly installed on the inside of another notch of the first annular connector 41;

[0051] The screw 442 is sleeved on the outside of the shaft 441, wherein the shaft 441 can rotate with the shaft 441 as the origin to the inside of another second notch of the second annular connector 43;

[0052] The first hand-tightening nut 443 is threaded onto the outside of the screw 442. One side surface of the first hand-tightening nut 443 is in contact with the surface of the second annular connector 43. The shaft 441 is fixedly installed inside another notch of the first annular connector 41, serving as a reference point and support for the rotation of the screw 442. This design ensures that the screw 442 can rotate stably around the shaft 441 without deviation or wobbling. The screw 442 is sleeved on the outside of the shaft 441, and its design allows the screw 442 to rotate around the shaft 441 as the origin to the inside of another second notch of the second annular connector 43. This rotational action is... The key step in achieving clamping is to allow the screw 442 to gradually approach and eventually make contact with the second annular connector 43. The first hand-tightening nut 443 is threaded to the outside of the screw 442. Its design allows the operator to adjust the extension length of the screw 442 by rotating the first hand-tightening nut 443, thereby achieving the clamping force between the first annular connector 41 and the second annular connector 43. When one side surface of the first hand-tightening nut 443 contacts the surface of the second annular connector 43 and continues to rotate, it will push the second annular connector 43 closer to the first annular connector 41 until the two are tightly pressed together.

[0053] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 3 As shown, both the first annular connector 41 and the second annular connector 43 have recessed notches on their surfaces near the first experimental connecting seat 1, which are adapted to the outer wall of the first experimental connecting seat 1. These recessed notches allow the first annular connector 41 and the second annular connector 43 to more tightly wrap around the outer wall of the first experimental connecting seat 1 when they are fitted together. This tight fit not only enhances the connection strength between the clamping assembly and the experimental connecting seat but also ensures the flatness and sealing of the connection point.

[0054] In a preferred embodiment, this utility model can be further configured as follows: Figure 2 , Figure 4 As shown; the second clamping assembly 5 includes:

[0055] The first clamping element 51 is located on the outside of the second experimental connecting seat 2;

[0056] The second clamping member 52 is disposed on the outside of the second experimental connecting seat 2, wherein the first clamping member 51 and the second clamping member 52 are combined together and closely attached to the outside of the second experimental connecting seat 2;

[0057] A connecting bolt 53 passes through the first clamping member 51 and connects to the second clamping member 52. The connecting bolt 53 connects the first clamping member 51 and the second clamping member 52 together. The second clamping assembly 5 mainly consists of the first clamping member 51, the second clamping member 52, and the connecting bolt 53. Both the first clamping member 51 and the second clamping member 52 are located on the outside of the second experimental connecting seat 2, and their design allows them to be combined and closely fitted to the outside of the second experimental connecting seat 2. This close-fitting design not only increases the contact area between the clamping assembly and the experimental connecting seat but also improves the clamping effect and helps reduce gaps. The connecting bolt 53 serves as the connection between the first clamping member 51 and the second clamping member 52. The key component of the second clamping member 52 is designed to allow bolts to pass through the reserved holes in the first clamping member 51 and connect with the corresponding threaded holes on the second clamping member 52. When the operator tightens the connecting bolts 53, the first clamping member 51 and the second clamping member 52 will be tightly pulled together, thereby achieving effective clamping at the connection between the second experimental connecting seat 2 and the experimental specimen 3. Through this design, the second clamping assembly 5 not only enhances the connection strength between the second experimental connecting seat 2 and the experimental specimen 3, but also significantly improves the sealing performance of the connection. During the experiment, even when faced with challenges from external factors such as oil pressure, the clamping assembly can ensure that the connection remains tight and seamless, thereby effectively preventing oil leakage.

[0058] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 4 As shown, both the first clamping member 51 and the second clamping member 52 have arc-shaped notches on their surfaces near the second experimental connecting seat 2, which are adapted to the outer wall of the second experimental connecting seat 2. There are two connecting bolts 53, which are respectively set on the two ends of the first clamping member 51 and the second clamping member 52. The arc-shaped notch design not only enhances the contact area between the clamping member and the experimental connecting seat, but also allows the clamping member to wrap more tightly around the outer wall of the experimental connecting seat, thereby reducing the generation of gaps. This tight fit is the key to achieving effective clamping and preventing leakage. The number of connecting bolts 53 is set to two, and they are respectively set on the two ends of the first clamping member 51 and the second clamping member 52. This layout not only ensures that the clamping member is evenly stressed in the length direction, but also improves the overall stability and reliability of the clamping assembly. When the connecting bolts 53 are tightened, the first clamping member 51 and the second clamping member 52 will be pulled tightly together, thereby achieving effective clamping at the connection between the second experimental connecting seat 2 and the experimental specimen 3.

[0059] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 2 and Figure 5 As shown; the stabilizing element 6 includes:

[0060] There are six long screws 61, which are divided into two groups. One end of one group of long screws 61 is fixedly connected to the surface of the first annular connector 41, and the other end passes through the entire first clamping member 51. The other end of the long screws 61 is fixedly connected to the surface of the second annular connector 43, and the other end passes through the entire second clamping member 52.

[0061] The second hand-tightening nut 63 is threaded onto the outside of the long screw 61. The long screw 61 is provided to ensure that the first clamping assembly 4 and the second clamping assembly 5 remain parallel to each other during the triaxial compression test. At the same time, round holes are provided on the surfaces of the first clamping member 51 and the second clamping member 52. The purpose of these round holes is to ensure that the long screw 61 can move within these holes without obstructing its movement trajectory. The second hand-tightening nut 63 is provided to prevent the second clamping assembly 5 from detaching from the surface of the long screw 61. This ensures that the first clamping assembly 4, the second clamping assembly 5, and the stabilizing member 6 are integrated as a whole during subsequent disassembly and storage, without affecting the overall effect of the triaxial compression test.

[0062] In a preferred embodiment, this utility model can be further configured as follows: Figure 2 As shown, the surfaces of the first annular connector 41, the second annular connector 43, the first clamping member 51, and the second clamping member 52 are all equipped with a level 7. During the experimental preparation stage, the operator can observe the level 7 embedded in the surfaces of the first annular connector 41, the second annular connector 43, the first clamping member 51, and the second clamping member 52 to determine whether these components are in a horizontal state. If any component is found to be tilted or misaligned, the operator can make timely adjustments to ensure the overall stability and accuracy of the experimental device.

[0063] The specific working principle of the anti-leakage and stabilizing device based on triaxial compression experiment of this utility model is as follows:

[0064] First, place the experimental specimen 3 between the first experimental connector 1 and the second experimental connector 2, ensuring that the experimental specimen 3 is aligned with the connection points of the two experimental connectors;

[0065] Next, install the first clamping assembly 4, and fit the first annular connector 41 onto the outside of the first experimental connector 1, ensuring that its concave notch matches the outer wall of the first experimental connector 1. At this time, the second annular connector 43 can be rotated and connected to the first annular connector 41 through the connector 42, so that it is placed on the outside of the first experimental connector 1. Rotate the first hand-tightening nut 443 to press the first annular connector 41 and the second annular connector 43 tightly on the outside of the first experimental connector 1. Observe the level 7 to ensure that the first annular connector 41 and the second annular connector 43 are in a horizontal state.

[0066] The first clamping member 51 and the second clamping member 52 are respectively fitted onto the outside of the long screw 61, and the first clamping member 51 and the second clamping member 52 are combined and fitted onto the outside of the second experimental connecting seat 2. Then, the connecting bolt 53 is used to pass through the first clamping member 51 and connect to the second clamping member 52, pressing the first clamping member 51 and the second clamping member 52 onto the outside of the second experimental connecting seat 2. Similarly, the first clamping member 51 and the second clamping member 52 are ensured to be in a horizontal state by observing the level 7.

[0067] During the experiment, the level indicator 7 can be continuously observed to ensure that all components remain level, avoiding experimental errors and leakage problems caused by tilting or misalignment. After the experiment, the device is disassembled in reverse order for the next experiment or maintenance.
