Description

Technical Field

[0001] This utility model relates to the technical field of three-dimensional visualization true triaxial simulation test bench, and in particular to a three-dimensional visualization true triaxial simulation test bench. Background Technology

[0002] In geotechnical engineering simulation and testing, true triaxial testing is required. This method simulates materials under three independently applied stresses (σ1, σ2, σ3) in three mutually perpendicular directions. It overcomes the limitations of traditional triaxial testing where σ2=σ3, realistically reflecting the influence of complex stress states on the mechanical properties of materials. By independently controlling the three principal stresses (σ1>σ2>σ3), the strength, deformation, and failure modes of materials under asymmetric stress conditions can be studied. For example, in rock mechanics research, it can simulate multi-directional stress environments under geological structures or engineering disturbances. In existing technologies, true triaxial simulation test benches are typically used to test rocks. However, the test chambers of existing true triaxial simulation test benches are usually made of sealed steel plates, which is not conducive to normal camera shooting. Furthermore, when compressing the side of the rock, hydraulic rods are usually installed on two side pressure plates. The hydraulic rods drive the side pressure plates to move and compress the rock from the side. It is difficult to ensure that the pressure of the two hydraulic rods is synchronized, which affects the test results. Therefore, a three-dimensional visualization true triaxial simulation test bench is designed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing a three-dimensional visualization true triaxial simulation test bench.

[0004] The technical problem to be solved by this utility model is to provide a three-dimensional visualization true triaxial simulation test bench to solve the problems of existing three-dimensional visualization true triaxial simulation test benches.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A three-dimensional visualization true triaxial simulation test bench includes a base, a test box, a door, transparent glass, a first hydraulic rod, an upper pressure plate, and side pressure plates. The test box is fixedly installed in the center of the upper surface of the base. The door is rotatably mounted on the outer surface of the test box via hinges. Transparent glass is embedded in the center of the door and the back of the test box. The first hydraulic rod is installed in the center of the upper surface of the test box. The upper pressure plate is fixedly installed at the output end of the first hydraulic rod. Side pressure plates are installed on the left and right sides of the test box via mounting components. A drive component is installed above the test box to drive the side pressure plates to move towards the center of the test box.

[0006] Preferably, the transparent glass is made of tempered glass.

[0007] Preferably, the mounting assembly includes a through rod, a through groove, and a spring. The through rod passes through the left and right surfaces of the test box, and a side pressure plate is fixedly disposed at the end of the through rod. A through groove is provided on the upper surface of the through rod. A spring is fixedly disposed between the inner surface of the test box and the side pressure plate, and the spring is sleeved on the through rod.

[0008] Preferably, when the spring is in its naturally extended state, the through groove on the through rod is completely outside the test box.

[0009] Preferably, the driving assembly includes a bracket fixed to the upper surface of the test box, a second hydraulic rod fixedly disposed at the center of the upper surface of the bracket, a lifting plate installed at the output end of the second hydraulic rod, trapezoidal inserts fixedly disposed on both the left and right sides of the lifting plate, and guide sleeves fixedly disposed on both the left and right sides of the test box, with the trapezoidal inserts penetrating through the guide sleeves.

[0010] Preferably, the trapezoidal insert plate matches the through groove, and the bottom of the trapezoidal insert plate is pointed with a reduced thickness component.

[0011] Preferably, the two trapezoidal inserts are positioned on one side directly above the through slot.

[0012] Preferably, the surface of the trapezoidal insert away from the test box and the surface of the through groove near the test box are on the same vertical plane.

[0013] Preferably, when the second hydraulic rod is extended to its maximum length, the bottom horizontal height of the trapezoidal insert is higher than the horizontal height of the through rod, and when the second hydraulic rod is extended to its minimum length, the bottom horizontal height of the trapezoidal insert is lower than the bottom horizontal height of the through rod.

[0014] Preferably, multiple LED lights are fixedly installed on the top of the inner surface of the test box.

[0015] In the above scheme, by placing the rock to be tested into the test box, the first hydraulic rod drives the upper pressure plate to move downward, thereby detecting the change in the vertical compression state of the rock. At the same time, the drive assembly drives the two side pressure plates to move towards the center of the test box, thereby detecting the lateral pressure of the rock.

[0016] In the above scheme, by setting up a drive component and an installation component, when the rock is subjected to lateral compression, the second hydraulic rod retracts, which drives the lifting plate to move downward. The lifting plate drives the trapezoidal insert plate to move downward, and the trapezoidal insert plate inserts into the through slot. This causes the two through rods to move simultaneously to one side of the test box. The side pressure plates on the through rods simultaneously apply lateral compression to the rock, ensuring balanced pressure during lateral compression and guaranteeing the test results. At this time, the spring is in a stretched state. When the compression ends, the second hydraulic rod drives the lifting plate and the trapezoidal insert plate to move upward. The trapezoidal insert plate disengages from the through slot, and the spring's rebound force causes the side pressure plate to return to its original position. This allows for changing the placement direction of the rock to achieve the effect of applying pressure to other sides for testing.

[0017] In the above scheme, LED lights are installed to illuminate the interior of the test chamber, increasing the brightness inside and facilitating the imaging of changes in the rock under pressure. Attached Figure Description

[0022] 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.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] like Figures 1-4 As shown, an embodiment of this utility model provides a three-dimensional visualization true triaxial simulation test bench, including a base 1, a test box 2, a door 3, a transparent glass 4, a first hydraulic rod 5, an upper pressure plate 6, and a side pressure plate 7. The test box 2 is fixedly installed in the center of the upper surface of the base 1. The door 3 is rotatably mounted on the outer surface of the test box 2 via a hinge. The transparent glass 4 is embedded in the center of the door 3 and the back of the test box 2. The first hydraulic rod 5 is installed in the center of the upper surface of the test box 2. The upper pressure plate 6 is fixedly installed at the output end of the first hydraulic rod 5. The side pressure plates 7 are installed on the left and right sides of the test box 2 via mounting components. A driving component is installed above the test box 2 to drive the side pressure plates 7 to move towards the center of the test box 2.

[0025] In this embodiment, the transparent glass 4 is made of tempered glass to ensure its strength and prevent damage.

[0026] During the test, the rock to be tested is placed in the test box 2, and the first hydraulic rod 5 drives the upper pressure plate 6 to move downward, so as to detect the change in the vertical compression state of the rock. At the same time, the two side pressure plates 7 are driven by the drive component to move towards the center of the test box 2, so as to detect the lateral pressure of the rock.

[0027] By embedding transparent glass 4 in the center of the door body 3 and on the back of the test box 2, it is convenient to photograph the morphological changes of rocks during the compression process through the transparent glass 4 on the front of the door body 3 and the transparent glass on the back of the test box 2, thus increasing practicality.

[0028] In this embodiment, the mounting assembly includes a through rod 8, a through groove 801, and a spring 802. The through rod 8 passes through the left and right surfaces of the test box 2. The side pressure plate 7 is fixedly installed at the end of the through rod 8. The through groove 801 is opened on the upper surface of the through rod 8. The spring 802 is fixedly installed between the inner surface of the test box 2 and the side pressure plate 7, and the spring 802 is sleeved on the through rod 8.

[0029] In this embodiment, when the spring 802 is in its natural extended state, the through groove 801 on the through rod 8 is completely outside the test box 2, which makes it convenient for the trapezoidal insert plate 12 on the drive assembly to be inserted into the through groove 801.

[0030] In this embodiment, the driving component includes a bracket 9 fixed on the upper surface of the test box 2. A second hydraulic rod 10 is fixedly disposed in the center of the upper surface of the bracket 9. A lifting plate 11 is installed at the output end of the second hydraulic rod 10. Trapezoidal inserts 12 are fixedly disposed on both the left and right sides of the lifting plate 11. Guide sleeves 13 are fixedly disposed on both the left and right sides of the test box 2, and the trapezoidal inserts 12 pass through the guide sleeves 13.

[0031] In this embodiment, the trapezoidal insert 12 matches the through groove 801, and the bottom of the trapezoidal insert 12 is pointed with a reduced thickness component.

[0032] In this embodiment, the two trapezoidal insert plates 12 are located on one side directly above the through slot 801, which facilitates the placement of the trapezoidal insert plates 12.

[0033] In this embodiment, the surface of the trapezoidal insert plate 12 away from the test box 2 and the surface of the through groove 801 close to the test box 2 are on the same vertical plane, which makes it convenient for the trapezoidal insert plate 12 to drive the two through rods 8 and the side pressure plate 7 to move simultaneously.

[0034] In this embodiment, when the second hydraulic rod 10 is extended to its maximum length, the bottom horizontal height of the trapezoidal insert plate 12 is higher than the horizontal height of the through rod 8, and when the second hydraulic rod 10 is extended to its minimum length, the bottom horizontal height of the trapezoidal insert plate 12 is lower than the bottom horizontal height of the through rod 8.

[0035] With the inclusion of a drive assembly and an installation assembly, when the rock is subjected to lateral compression, the second hydraulic rod 10 retracts, causing the lifting plate 11 to move downwards. The lifting plate 11 then moves the trapezoidal insert 12 downwards, inserting it into the through slot 801. This causes the two through rods 8 to move simultaneously to one side of the test box 2. The side pressure plates 7 on the through rods 8 simultaneously apply lateral compression to the rock, ensuring balanced pressure during lateral compression and guaranteeing test results. At this time, the spring 802 is in a stretched state. When the compression ends, the second hydraulic rod 10 moves the lifting plate 11 and the trapezoidal insert 12 upwards, causing the trapezoidal insert 12 to disengage from the through slot 801. The rebound force of the spring 802 causes the side pressure plate 7 to return to its original position, facilitating changes in the rock's placement direction to achieve the effect of applying pressure to other sides for testing.

[0036] In this embodiment, multiple LED lights 14 are fixedly installed on the top of the inner surface of the test box 2.

[0037] By incorporating an LED light 14, the interior of the test chamber 2 can be illuminated, increasing the brightness inside the test chamber 2 and facilitating the imaging of changes in the rock under pressure.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
