Description

Technical Field

[0001] The utility model relates to an anti-scour performance test device, in particular to an anti-scour performance test device for inorganic binder stabilized materials. Background Art

[0002] Inorganic binder-stabilized materials primarily refer to materials that enhance the stability and strength of soil or other substrates by adding inorganic binders (such as cement, lime, and soil). These materials are widely used in infrastructure projects such as roads, bridges, and dams to improve their durability and load-bearing capacity. To ensure their durability, they require impact resistance testing, typically using an anti-scour test device.

[0003] In traditional scour resistance test equipment, the test tank simulates the scour conditions in the actual environment. The scour device provides simulated water flow or other scour media, usually including nozzles, pump systems, etc. The sample table is used to fix the inorganic binder stabilized material sample to be tested, and is usually equipped with a clamp or fixture to ensure that the sample does not move during the test.

[0004] However, the flushing device in the traditional anti-scour test device is often a single nozzle. This flushing structure cannot adjust the size of the flushing water flow and cannot simulate the actual environmental conditions, which reduces the accuracy of the test and the evaluation of the anti-scour performance of the material. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an anti-scour performance test device for materials stabilized with inorganic binders, aiming to improve the problem that traditional anti-scour test devices cannot adjust the size of scouring water flow, reducing test accuracy and material anti-scour performance evaluation.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an inorganic binder stabilized material anti-scour performance test device, including a workbench, the top of the workbench is fixedly connected to a connecting pipe, the side wall of the connecting pipe is fixedly connected to a water inlet platform, the side wall of the water inlet platform is fixedly connected to a motor, the output end of the motor is fixedly connected to a transmission shaft, the inside of the connecting pipe is fixedly connected to a left-right symmetrical turntable 1, the transmission shaft is rotatably connected to the inside of the turntable 1, the outer wall of the transmission shaft is fixedly connected to a plurality of turntables, each of the turntable side walls is rotatably connected to a push-pull rod, one end of the push-pull rod is rotatably connected to a connecting column, a flow groove is provided inside the connecting column, the connecting column is slidably connected to the inside of the workbench, a water outlet is provided inside the workbench, and a test assembly is provided on the top of the workbench, and the test assembly is used to place the inorganic binder stabilized material sample to be tested.

[0007] Furthermore, the test assembly includes a test bench, which is fixedly connected to the upper surface of the workbench.

[0008] Furthermore, a plurality of turntables 2 are fixedly connected to the side walls of the workbench, and the turntables 2 are symmetrically distributed on both sides of the workbench.

[0009] Furthermore, both side walls of the turntable are fixedly connected with a supporting platform, the top of the supporting platform is fixedly connected with a hydraulic push rod, and the output end of the hydraulic push rod is fixedly connected with a push column.

[0010] Furthermore, the top of the push column is fixedly connected to a connecting platform, and the inside of the connecting platform is rotatably connected to a connecting rod.

[0011] Furthermore, a plurality of connecting shafts are rotatably connected inside the turntable 2, and an L-shaped rod is fixedly connected to the outer wall of the connecting shaft.

[0012] Furthermore, a rotating plate is fixedly connected to the outer wall of the other connecting shaft, and a transition plate is rotatably connected between the L-shaped rod and the rotating plate.

[0013] Furthermore, the transition plate is rotatably connected to the outer wall of the connecting rod, and the top of the L-shaped rod is fixedly connected to a pressing platform.

[0014] The utility model has the following beneficial effects:

[0015] In this utility model, the motor first generates output to the drive shaft, driving its rotation. Ultimately, the water flow rate from the outlet is adjusted based on the distance the connecting column leaves the flow channel within the connecting pipe. The intensity and velocity of water flow vary significantly in different engineering environments. For example, the velocity of water flow under highways and bridges may differ from that in rivers. By adjusting the water flow rate, different scour conditions can be simulated, thereby evaluating the material's performance in real-world applications. This simulation helps ensure that the material has sufficient scour resistance in real-world environments.

[0016] 2. In the present invention, the hydraulic push rod outputs the push column to push the push column to vertically move, and finally the L-shaped rod and the connecting shaft inside the rotating plate will rotate synchronously inside the turntable 2 to keep the rotation process stable. When the L-shaped rod rotates, the change in its angle will drive the pressing table to move downward. The downward displacement of multiple pressing tables will press down and fix the test material, so that it maintains a stable position on the surface of the test table, ensuring that the sample will not move during the test process, and ensuring the accuracy of the scouring test results.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 2 , the utility model provides an embodiment: an inorganic binder stabilized material anti-scour performance test device, including a workbench 1, characterized in that: the top of the workbench 1 is fixedly connected to a connecting pipe 2, the side wall of the connecting pipe 2 is fixedly connected to a water inlet platform 3, the side wall of the water inlet platform 3 is fixedly connected to a motor 4, the output end of the motor 4 is fixedly connected to a transmission shaft 5, the inside of the connecting pipe 2 is fixedly connected to a left-right symmetrical turntable 6, the transmission shaft 5 is rotatably connected to the inside of the turntable 6, and the outer wall of the transmission shaft 5 is fixedly connected to a plurality of rotating racks 7, each rotating rack 7 side wall is rotatably connected to a push-pull rod 8, one end of the push-pull rod 8 is rotatably connected to a connecting column 9, a flow trough 10 is opened inside the connecting column 9, the connecting column 9 is slidably connected to the inside of the workbench 1, and a water outlet 11 is opened inside the workbench 1, and a test assembly is provided on the top of the workbench 1, which is used to place the inorganic binder stabilized material sample to be tested.

[0024] Specifically, when it is necessary to adjust the size of the water flow of the connecting pipe 2 to the test material on the surface of the test bench 12, the motor 4 is started first. The motor 4 rotates the transmission shaft 5 through its driving system, so that the transmission shaft 5 rotates stably inside the turntable 6 to ensure the stability of the transmission shaft 5. During the rotation of the transmission shaft 5, it will drive the rotating frame 7 on its outer wall to move synchronously and adjust its own inclination angle. The side wall of the rotating frame 7 and the push-pull rod 8 connected to its rotation are displaced, thereby pushing the connecting column 9 at one end of the push-pull rod 8. After receiving the driving force, the connecting column 9 will slide inside the connecting pipe 2. A plurality of flow grooves 10 are provided inside the connecting column 9. These flow grooves 10 The design allows the connecting column 9 to gradually reveal flow channels 10 of different lengths as it slides inside the connecting pipe 2. The revealed length of the flow channel 10 determines the flow rate of water through the outlet 11. In different engineering environments, the intensity and speed of water flow vary significantly. For example, the water flow speed under highways and bridges may be very different from the water flow speed in rivers. By adjusting the water flow size, different scouring conditions can be simulated in the test, thereby comprehensively evaluating the performance of the material in actual application. This simulation can not only reflect the material's anti-scouring ability in a real environment, but also ensure that the material can maintain its long-term stability and performance when facing various scouring environments.

[0025] Reference Figure 3 The test assembly includes a test table 12, which is fixedly connected to the upper surface of the workbench 1. A plurality of turntables 13 are fixedly connected to the side walls of the workbench 1. The turntables 13 are symmetrically distributed on both sides of the workbench 1. The side walls of the turntables 13 are fixedly connected to a support platform 14. The top of the support platform 14 is fixedly connected to a hydraulic push rod 15. The output end of the hydraulic push rod 15 is fixedly connected to a push column 16. The top of the push column 16 is fixedly connected to a connecting platform 17. The connecting platform 17 is rotatably connected to a connecting rod 18. The turntable 13 is rotatably connected to a plurality of connecting shafts 19. The outer wall of the connecting shaft 19 is fixedly connected to an L-shaped rod 21. The outer wall of another connecting shaft 19 is fixedly connected to a rotating plate 20. A transition plate 22 is rotatably connected between the L-shaped rod 21 and the rotating plate 20. The transition plate 22 is rotatably connected to the outer wall of the connecting rod 18. The top of the L-shaped rod 21 is fixedly connected to a pressing platform 23.

[0026] Specifically, when the test material needs to be fixed on the surface of the test table 12, the hydraulic push rod 15 is first started. The hydraulic push rod 15 is stably supported by the support table 14 to ensure the stability of its operation. Under the push of the hydraulic push rod 15, the push column 16 begins to move vertically. The movement of the push column 16 drives the connecting table 17 to move synchronously and causes the angle of the connecting rod 18 inside it to change. The other end of the connecting rod 18 is connected to the internal rotation of the transition plate 22, so that the transition plate 22 also drives the rotation of the L-shaped rod 21 and the rotating plate 20 during the synchronous movement. The connecting shaft 19 inside the L-shaped rod 21 and the rotating plate 20 will rotate synchronously inside the turntable 2 13 to maintain the stability of the rotation process. When the L-shaped rod 21 rotates, the change in its angle will cause the pressing platform 23 to move downward. During the downward displacement process, multiple pressing platforms 23 will gradually apply pressure to the test material, thereby effectively fixing the test material. This can ensure that the sample will not move during the test process, thereby ensuring the accuracy of the scouring test results.

[0027] Working Principle: When it is necessary to adjust the water flow rate of the connecting pipe 2 to the test material on the surface of the test bench 12, the motor 4 is started. The motor 4 outputs to the transmission shaft 5, causing the transmission shaft 5 to rotate. The rotation process of the transmission shaft 5 is ensured inside the turntable 6. During the rotation of the transmission shaft 5, the rotating frame 7 on its outer wall is driven to move synchronously and change its own tilt angle. The push-pull rod 8 connected to the side wall of the turntable 7 and its rotation can be displaced, pushing and pulling the connecting column 9 at one end. When the connecting column 9 is subjected to force, it will slide inside the connecting pipe 2. There are multiple flow channels 10 inside the connecting column 9. The size of the water flow out of the water outlet 11 is adjusted according to the distance that the connecting column 9 leaks out of the flow channels 10 inside the connecting pipe 2. The strength and speed of the water flow in different engineering environments vary greatly. For example, the water flow speed under highways and bridges may be different from that in rivers. By adjusting the water flow rate, different flushing conditions can be simulated, thereby evaluating the performance of materials in actual applications. This simulation helps to ensure that the material has sufficient anti-scouring ability in a real environment. When the test material needs to be fixed on the surface of the test bench 12, the hydraulic push rod 15 is started, and the support platform 14 provides support for the hydraulic push rod 15. The hydraulic push rod 15 outputs to the push column 16 to push the push column 16 vertically. During the movement of the push column 16, the connecting platform 17 is driven to move synchronously and the angle of the connecting rod 18 inside it changes. The other side of the connecting rod 18 rotates and is connected to the inside of the transition plate 22, so that the transition plate 22 drives the L-shaped rod 21 and the rotating plate 20 to rotate synchronously. The connecting shaft 19 inside the L-shaped rod 21 and the rotating plate 20 will rotate synchronously inside the turntable 2 13 to keep the rotation process stable. When the L-shaped rod 21 rotates, the change in its angle will drive the press platform 23 to move downward. The downward displacement of multiple press platforms 23 will effectively fix the test material, ensure that the sample will not move during the test, and ensure the accuracy of the scouring test results.
