Abstract
Description
Technical Field
[0001] This invention belongs to the field of modified rubber concrete testing technology, specifically relating to a rubber concrete block strength testing device. Background Technology
[0002] With the increasing demand for diversified material performance in the construction industry, modified rubber concrete, with its excellent crack resistance, toughness, and environmental protection characteristics (recyclable waste rubber), is widely used in road engineering, water conservancy facilities, building foundations, and other fields. The strength indicators of this type of concrete (such as impact strength and vibration fatigue strength) directly determine the safety and service life of the engineering structure. Therefore, accurate strength testing is a key prerequisite for its widespread application.
[0003] Most existing devices can only perform a single type of strength test (such as impact test or pressure test only), and cannot simultaneously perform multi-dimensional tests such as impact resistance and vibration resistance. If comprehensive strength data is required, the concrete block needs to be transferred to different devices, which is not only cumbersome and time-consuming, but may also affect the test accuracy due to damage to the block or changes in the environment during the transfer process.
[0004] Furthermore, current tests on concrete blocks often involve applying force directly to the concrete block. If the steel structure or other structures connected to the concrete block are subjected to external impact, the structural stability of the concrete block will still be affected.
[0005] Therefore, a rubber concrete block strength testing device was designed to overcome the above-mentioned technical defects. Summary of the Invention

[0020] Example 1: This specific embodiment is a rubber concrete block strength testing device, the structural schematic diagram of which is shown below. Figures 1-6 As shown, the device includes a base plate 1, a protective shell 2 fixedly connected to the top surface of the base plate 1, two concrete blocks 3 on the top surface of the base plate 1, a steel structure 4 embedded between the two concrete blocks 3, and two limiting rings 25 mounted on the top surface of the base plate 1. The limiting rings 25 are connected to the base plate 1 by bolts. In actual use, their positions can be adjusted according to the specifications of the concrete blocks 3. A circular hole is opened on the top surface of the protective shell 2, and an annular plate 5 is rotatably connected inside the circular hole. An mounting plate 6 is fixedly connected to the inner wall of the annular plate 5. A rotating component is provided on the side wall of the annular plate 5, and an impact detection component and a vibration detection component are provided on the side wall of the mounting plate 6. Protective doors 24 are respectively mounted on the front and rear side walls of the protective shell 2.
[0021] The connection methods between concrete block 3 and steel structure 4 include the following, all of which require pre-casting and solidification before testing to achieve the strength under normal use conditions: Concrete block 3 was prepared separately and tested independently. Prepare hollow or recessed concrete blocks separately; The steel structure 4 has concrete blocks 3 penetrating at both ends; The steel structure 4 does not penetrate the concrete block 3 at either end, but is embedded inside the concrete block 3; Among them, the steel structure 4 can be other steel structures such as I-beams, H-beams, and steel pipes, which can simulate the connection strength test between different steel structures 4 and concrete blocks 3.
[0022] like Figure 1 and Figure 2 As shown, the rotating assembly includes a support plate 11 mounted on the top surface of the protective shell 2. A first motor 12 is mounted on the top surface of the support plate 11. A gear 13 is fixedly connected to the output shaft of the first motor 12. An annular rack 14 is fixedly connected to the side wall of the annular plate 5, and the gear 13 meshes with the annular rack 14. The rotating assembly is used to control the position switching of the impact detection assembly and the vibration detection assembly. It rotates 180° in a single operation, which facilitates the interchange of the impact detection assembly and the vibration detection assembly in the center position of the protective shell 2, making it convenient to test the concrete block 3.
[0023] Example 2: like Figure 3 , Figure 5 and Figure 6 As shown, the impact detection assembly includes a first hydraulic cylinder 7 fixedly connected to the top surface of the mounting plate 6 near the left side. A docking block 8 is fixedly connected to the end face of the telescopic end of the first hydraulic cylinder 7, and an impact block 9 is detachably connected to the bottom surface of the docking block 8.
[0024] A stud 10 is fixedly connected to the top of the impact block 9, and a threaded hole is opened on the bottom surface of the mating block 8. The stud 10 is threadedly connected to the threaded hole. The impact block 9 can be either conical or flat.
[0025] Specifically, during testing, different shaped impact blocks 9 are used according to testing requirements. When it is necessary to conduct an impact resistance test on the concrete block 3, the concrete block 3 is placed separately in the middle of the base plate 1. First, the conical impact block 9 is used to impact the concrete block 3 at different falling speeds, and the degree of damage to the surface of the concrete block 3 is recorded each time it is impacted. When it is necessary to conduct a compressive strength test on the surface of concrete block 3, the conical impact block 9 is replaced with a flat impact block 9, and different pressures are applied to the surface of concrete block 3, and the changes of concrete block 3 under each pressure are recorded.
[0026] Alternatively, the independent concrete block 3 can be replaced with the above-mentioned steel structure 4, which has both ends penetrating the concrete block 3 or has both ends not penetrating the concrete block 3, and embedded inside the concrete block 3. By using impact blocks 9 of different shapes, the force is applied to the steel structure 4, and the connection stability, deformation, and loosening of the steel structure 4 and concrete block 3 are judged under different pressures.
[0027] Example 3: like Figure 3 and Figure 4As shown, the vibration detection assembly includes a connecting plate 15 disposed inside the protective shell 2. The connecting plate 15 is U-shaped. A second motor 16 is installed on the side wall of the connecting plate 15. A cam 17 is fixedly connected to the output shaft of the second motor 16. The bottom surface of the connecting plate 15 is movably connected to a telescopic rod 18. The top end of the telescopic rod 18 abuts against the side wall of the cam 17. A striking ball 19 is fixedly connected to the bottom end of the telescopic rod 18. An elastic component is provided on the side wall of the telescopic rod 18. A driving component is provided on the upper side of the mounting plate 6.
[0028] Specifically, based on embodiments 1-2, this embodiment replaces the vibration detection component with the center position of the protective shell 2. By replacing different precast concrete blocks 3 and steel structures 4, the vibration resistance data of concrete blocks 3 and steel structures 4 at different vibration frequencies are detected, and the damage degree of concrete blocks 3, the connection strength between concrete blocks 3 and steel structures 4, and the deformation of steel structures 4 are determined.
[0029] like Figure 4 As shown, the elastic component includes a baffle 20 fixedly connected to the side wall of the telescopic rod 18, and a spring 21 is sleeved on the side wall of the telescopic rod 18 between the baffle 20 and the connecting plate 15. A roller 22 is mounted on the top of the telescopic rod 18, and the roller 22 abuts against the cam 17.
[0030] The spring 21 is used to keep the telescopic rod 18 in contact with the side wall of the cam 17 to ensure the rebound performance of the ball 19. At the same time, the roller 22 can reduce the friction between the telescopic rod 18 and the cam 17 and extend its service life.
[0031] like Figure 2 and Figure 3 As shown, the driving component includes a second hydraulic cylinder 23, the telescopic end of which is fixedly connected to the top surface of the connecting plate 15. The second hydraulic cylinder 23 can be replaced with other structures such as a pneumatic cylinder, an electric actuator, or a linear motor, depending on assembly requirements.
[0032] Working principle: First, the precast concrete block 3 and steel structure 4 are placed in the limiting ring 25. Then, the position of the impact detection component or vibration detection component is adjusted according to the detection requirements. The impact detection component is initially opposite to the steel structure 4. When it is necessary to detect the connection strength or compressive strength between the concrete block 3 and the steel structure 3, the first hydraulic cylinder 7 is activated to drive the impact block 9 to move downward. The impact block 9 abuts against the steel structure 4 and applies force to the steel structure 4 to determine the connection stability or loosening deformation data between the concrete block 3 and the steel structure 4 under different pressures. If it is necessary to determine the vibration resistance between the concrete block 3 and the steel structure 4, the first motor 12 is started to drive the gear 13 to rotate. The gear 13 meshes with the ring rack 14 to drive the ring plate 5 to rotate. The ring plate 5 drives the mounting plate 6 to rotate 180°, which is used to rotate the vibration detection component above the steel structure 4. Then, the second hydraulic cylinder 23 is started. The second hydraulic cylinder 23 drives the ball 19 to move downward to a suitable position through the connecting plate 15. Then, the second motor 16 is started. The output shaft of the second motor 16 drives the cam 17 to rotate. The cam 17 drives the ball 19 to reciprocate through the telescopic rod 18, which strikes the steel structure 4 to generate vibration. By adjusting the striking frequency, the connection strength between the concrete block 3 and the steel structure 4 is tested.
[0033] All technical features in this embodiment can be freely combined according to actual needs.
[0034] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
