[0032] 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.

[0033] Reference Figure 1 , Figure 3 Figure 4This utility model provides an embodiment of an auxiliary device for measuring concrete bond strength, comprising a base 1. The base 1 serves as the basic support structure for the entire device, providing a stable installation position for other components and ensuring the stability of the entire device during operation. Extension plates 2 are fixedly connected to both sides of the base 1, and a top plate 3 is fixedly connected to the top of the adjacent side of the two extension plates 2. The top plate 3 can be used to install components such as hydraulic cylinders 4, and also provides some protection and support from above.

[0034] A hydraulic cylinder 4 is fixedly connected to the top of the top plate 3. As a power drive component, the hydraulic cylinder 4 generates a linear pushing force, driving the connected components to move accordingly, playing a crucial power transmission role in the operation of the entire device. A movable plate 5 is fixedly connected to the drive end of the hydraulic cylinder 4. The movable plate 5 moves with the drive of the hydraulic cylinder 4, thereby driving the connected components below to perform corresponding actions, making it an important structure connecting different components. A suction cup 6 is fixedly connected to the bottom of the movable plate 5. The suction cup 6 can tightly adhere to the surface of the floor tile 17 to be tested, relying on suction to adhere it, thereby enabling the measurement of the bond strength of the concrete 16 in subsequent operations.

[0035] A drive assembly is fixedly connected to the inner wall of the base 1. This drive assembly is crucial for controlling the position of the wall block 15, ensuring its stability during testing. A rotating disk 9 is rotatably connected to the inner wall of the base 1. The rotating disk 9 serves as an intermediate transmission structure, driving other components through its rotation to achieve the positioning of the wall block 15. The drive assembly includes a motor 7, which is externally fixed to the inner wall of the base 1. The motor 7 acts as a power source, providing initial power for the entire drive assembly. Upon startup, it drives related components to rotate, making it key to the drive assembly's operation. A drive gear 8 is fixedly connected to the drive end of the motor 7. Driven by the motor 7, the drive gear 8 rotates and transmits power through meshing with other components, achieving the corresponding mechanical transmission effect. Teeth 10 are fixedly connected to the inner wall of the rotating disk 9. These teeth mesh with the drive gear 8, allowing the drive gear 8 to rotate and drive the rotating disk 9, completing the power transmission and conversion, thus enabling the entire device to operate in a predetermined manner.

[0036] The top of the rotating disk 9 has multiple grooves 11, which provide tracks for the movement of the slider 13, allowing it to slide along a predetermined path and ensuring the directionality and stability of subsequent components. The slider 13 is slidably connected to the inner wall of the groove 11, allowing it to slide flexibly within the groove and converting the rotation of the rotating disk 9 into its own linear movement, thereby driving other components to perform corresponding actions. The top of the base 1 is fixedly connected to multiple slide rails 12, which cooperate with the slider 13 to further ensure the smooth movement of the slider 13, preventing any instability such as deviation during movement, thus making the entire device more reliable.

[0037] Multiple sliders 13 are slidably connected to one side of multiple slide rails 12. A positioning block 14 is fixedly connected to the top of each slider 13. The positioning block 14 moves with the slider 13, effectively clamping and positioning the wall block 15 to prevent displacement during testing and affecting the test results. The adjacent sides of the positioning blocks 14 contact the outside of the wall block 15. The wall block 15, as the foundation structure supporting the concrete 16, is placed on top of the base 1 and is the crucial load-bearing component for the entire bond strength test; the concrete 16 will be bonded to it. The slider 13 is slidably connected to the inner wall of the slide groove 11 via a bottom protrusion. This connection method ensures smooth sliding of the slider 13 within the slide groove 11 and a stable connection, making power transmission more stable and reliable.

[0038] refer to Figure 1 , Figure 2 and Figure 5 A wall block 15 is placed on top of the base 1, and concrete 16 is bonded to the top of the wall block 15. Concrete 16 is a key material for testing the bonding strength, and its adhesion to the wall block 15 and the floor tile 17 is the focus of this test. Subsequent operations will be used to check whether its bonding strength meets the requirements. Floor tile 17 is bonded to the top of the concrete 16. Floor tile 17 is the object that the device will attract and pull during the test. After being attracted by suction cup 6, an upward pulling force is used to simulate the external forces that may occur in actual use, thereby testing the bonding strength between concrete 16 and the wall block 15 and floor tile 17.

[0039] A vacuum pump 18 is fixedly connected to the inner wall of the top plate 3. The vacuum pump 18 generates negative pressure, which extracts air from the suction cup 6 through the connecting pipe 19, allowing the suction cup 6 to adhere tightly to the surface of the floor tile 17. This provides the necessary adsorption force for subsequent adhesion strength testing. The output end of the vacuum pump 18 is fixedly connected to the connecting pipe 19, which serves as a gas transmission channel, transferring the negative pressure generated by the vacuum pump 18 to the inside of the suction cup 6, ensuring that the suction cup 6 can perform its adsorption function normally. The other end of the connecting pipe 19 passes through the moving plate 5 and is fixedly connected to one side of the suction cup 6. This connection method ensures the continuity of the negative pressure transmission path from the vacuum pump 18 to the suction cup 6, enabling the entire adsorption system to work effectively.

[0040] Both sides of the movable plate 5 are fixedly connected to limiting blocks 20. The limiting blocks 20 can restrict and guide the movement of the movable plate 5, ensuring that the movable plate 5 moves along a predetermined trajectory under the drive of the hydraulic cylinder 4, preventing abnormal situations such as skewing. The top of the limiting block 20 is fixedly connected to a movable column 21. The movable column 21 moves with the limiting block 20, playing a role in transmitting force, transferring the force received by the limiting block 20 to subsequent components. The top of the movable column 21 is fixedly connected to a circular block 22. The circular block 22 can move accordingly after receiving the force transmitted by the movable column 21, and interacts with components such as the spring 24 to achieve buffering functions. The outside of the circular block 22 is slidably connected to a limiting sleeve 23. The limiting sleeve 23 restricts the movement range of the circular block 22, ensuring that the circular block 22 moves within a reasonable range, and can better play a buffering role when cooperating with the spring 24. The external sliding connection of the limiting block 20 is located in the groove of the extension plate 2. This sliding connection method further ensures the smoothness and directionality of the movement of the moving plate 5, making the operation of the entire device more reliable.

[0041] The top of the limiting sleeve 23 is fixedly connected to the inner wall of the groove in the extension plate 2, ensuring the stability of the limiting sleeve 23 and providing a solid foundation for the normal operation of components such as the circular block 22. A spring 24 is fixedly connected to one inner wall of the limiting sleeve 23. The spring 24 is compressed and deformed when the circular block 22 moves. Its elasticity can absorb the impact force generated during the test, preventing damage to the device and affecting the accuracy of the test results. The other end of the spring 24 is fixedly connected to one side of the circular block 22. This connection method allows the spring 24 to cooperate with the circular block 22. When the circular block 22 is pushed by an external force, the spring 24 can deform in time to buffer and absorb energy.

[0042] Working principle: When the equipment is needed, the floor tile 17 is bonded to the concrete 16, and then the concrete 16 is bonded to the wall block 15. The wall block 15 is then placed on top of the base 1. The motor 7 is started, which drives the drive gear 8 to rotate. The rotation of the drive gear 8 meshes with the teeth 10, which in turn drives the rotating disk 9 to rotate. The rotation of the rotating disk 9 causes the sliding groove 11 on its surface to move, which in turn drives the slider 13 to move. The slider 13 moves along the surface of the slide rail 12 to ensure stable movement. Finally, the movement of the slider 13 drives the positioning block 14 to move, which clamps and positions the wall block 15.

[0043] At this point, by activating hydraulic cylinder 4, the moving plate 5 is moved, which in turn moves suction cup 6, allowing it to adhere to the floor tile 17. Then, vacuum pump 18 is activated to suck up connecting pipe 19, causing suction cup 6 to pick up floor tile 17. Again, by activating hydraulic cylinder 4, the moving plate 5 is raised, causing suction cup 6 to rise. The movement of moving plate 5 causes limiting block 20 to push moving column 21, which in turn pushes round block 22. When round block 22 moves, it compresses spring 24, causing spring 24 to deform and absorb the impact force generated during the test. Through the continuous movement of suction cup 6, the viscosity of concrete 16 can be measured, and the final result is displayed on the top screen of top plate 3.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
