Monopiles are driven into the seabed by hammering, vibration or rotation to form a stable foundation that can withstand various forces in the marine environment, such as wind, wave and current forces. Before the monopiles are processed and used, they must undergo shear stress testing to simulate the impact of offshore conditions on the monopiles, evaluate the bearing capacity and stability of the monopile foundation, and provide important data support for engineering design and safety assessment.
[0003] The existing shear stress test device uses sensors and loading systems to simulate the mechanical effects in the actual marine environment by applying vertical and horizontal loads on the monopile foundation. The sensor collects the interface shear stress data in real time, and processes it through the data acquisition and analysis system to generate a detailed test report. The high-precision loading and data acquisition system of the device ensures the accuracy and reliability of the test results, which can help engineers better understand the stress conditions of the monopile foundation and improve the scientificity of the design and the safety of the project.
[0004] However, when the existing shear stress test device is performing a shear stress test, the position of the single pile is not stable enough and is prone to displacement during the test, which not only affects the accuracy of the test results, but may also cause equipment damage or test failure.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment: an offshore single pile interface shear stress testing device, comprising a bottom plate 1, a base 2 is fixedly connected to the upper surface of the bottom plate 1, a hydraulic rod 3 is fixedly connected to the inside of the base 2, a connecting rod 4 is fixedly connected to the output end of the hydraulic rod 3, a tooth plate 5 is fixedly connected to the outer wall of the connecting rod 4, a rotating shaft 7 is rotatably connected to the inside of the base 2, a gear 6 is fixedly connected to the outer wall of the rotating shaft 7, the gear 6 is meshed with the tooth plate 5, a rotating disk 8 is fixedly connected to the outer wall of the rotating shaft 7, and the rotating disk 8 is internally slidably connected to a limited position column 9, the outer wall of the limit column 9 is fixedly connected with a slide seat 10, the inner part of the slide seat 10 is slidably connected with a slideway 11, the outer wall of the slide seat 10 is fixedly connected with a support seat 12, the outer wall of the tooth plate 5 is fixedly connected with a connecting frame 13, the outer wall of the connecting frame 13 is fixedly connected with a clamping plate 14, and the upper surface of the bottom plate 1 is provided with a guide assembly, which is used for guiding and supporting the single pile when it moves; the guide assembly includes a sliding sleeve 15, the outer wall of the sliding sleeve 15 is fixedly connected to the upper surface of the bottom plate 1, and the inner part of the sliding sleeve 15 is rotatably connected with a guide roller 16;
[0025] Specifically, when it is necessary to fix the position of the single pile, the output end of the hydraulic rod 3 cooperates with the connecting rod 4 to drive the toothed plate 5 on one side to start moving, and the toothed plate 5 on this side meshes with the gear 6. The rotation of the gear 6 drives the toothed plate 5 on the other side to move simultaneously. This process continues until the clamp 14 completely clamps the single pile. At the same time, when the gear 6 rotates, the rotating shaft 7 drives the turntable 8 to rotate, and the turntable 8 pushes the slide 10 through the limit column 9, so that the slide 10 slides on the outer wall of the slideway 11. The movement of the slide 10 also drives the support seat 12 until the support seat 12 completely clamps and supports the single pile. This ensures that the single pile is firmly fixed and effectively supported during the test, improves the stability of the device and the reliability of operation, and ensures the smooth progress of the test process.
[0026] Reference Figure 2 and Figure 4, a support plate 17 is fixedly connected to the upper surface of the bottom plate 1, and a support platform 18 is fixedly connected to the outer wall of the support plate 17; a motor 19 is fixedly connected to the outer wall of the support platform 18, and a main sprocket 20 is fixedly connected to the output end of the motor 19; a secondary sprocket 22 is rotatably connected to the inside of the support platform 18, and a chain 21 is arranged inside the support platform 18, and the chain 21 is respectively meshed with the main sprocket 20 and the secondary sprocket 22; a movable plate 23 is rotatably connected to the outer wall of the chain 21, and a connecting plate 24 is slidably connected to the outer wall of the movable plate 23; a connecting seat 25 is fixedly connected to the outer wall of the connecting seat 25, and a steel rod dynamometer 27 is fixedly connected to the outer wall of the connecting seat 25; a limit rod 26 is fixedly connected to the inside of the support platform 18, and the outer wall of the limit rod 26 is slidably connected to the inside of the connecting seat 25;
[0027] Specifically, when the position of the steel rod dynamometer 27 needs to be adjusted, the main sprocket 20 is driven to start rotating through the output end of the motor 19, and the main sprocket 20 drives the secondary sprocket 22 to rotate synchronously through the chain 21. The movement of the secondary sprocket 22 drives the movable plate 23 to slide along the chain 21 inside the support platform 18. While the movable plate 23 slides, the connecting plate 24 can reciprocate inside the support platform 18, which allows the connecting seat 25 and the steel rod dynamometer 27 to move in conjunction. At the same time, the limit rod 26 limits the position of the connecting seat 25 to ensure that the steel rod dynamometer 27 is accurately adjusted within the necessary range. This not only achieves precise adjustment of the position of the steel rod dynamometer 27, but also supports the multi-directional detection requirements of a single pile, improves the practicability of the device and the convenience of operation, and makes the detection of a single pile more efficient and accurate.
[0028] Working principle: when the position of the single pile needs to be fixed, the output end of the hydraulic rod 3 cooperates with the connecting rod 4 to drive the toothed plate 5 on one side to move, and then the toothed plates 5 on both sides are meshed with the gear 6, so that the toothed plate 5 on one side can be driven by the gear 6 to move together with the toothed plate 5 on the other side, until the clamping plate 14 completely clamps the single pile, and then when the gear 6 rotates, the rotating shaft 7 can drive the turntable 8 to rotate, so that the turntable 8 can push the slide 10 through the limit column 9, and then drive the slide 10 to slide on the outer wall of the slideway 11 while driving the support seat 12, until the support seat 12 completely clamps and supports the single pile, thereby achieving the effect of firmly fixing the position of the single pile and supporting the single pile, improving the stability of the device and ensuring the measurement. In order to ensure the smooth progress of the test process, when the position of the steel rod dynamometer 27 needs to be adjusted, the main sprocket 20 is driven to rotate through the output end of the motor 19, so that the main sprocket 20 can cooperate with the chain 21 to drive the secondary sprocket 22 to rotate together, thereby driving the movable plate 23 to slide inside the support platform 18 following the chain 21, and then the movable plate 23 slides inside the connecting plate 24, so that the connecting plate 24 can make a reciprocating motion inside the support platform 18, thereby driving the connecting seat 25 and the steel rod dynamometer 27 to move together, wherein the limit rod 26 can limit the position of the connecting seat 25, thereby achieving the effect of adjusting the position of the steel rod dynamometer 27, realizing multi-directional detection of single piles, improving the practicability of the device, and facilitating the detection of single piles.
