Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, and in particular to a testing device for precast concrete components. Background Technology

[0002] Precast concrete, or simply "concrete," refers to a general term for engineering composite materials in which aggregates are bound together by a cementing material. Generally, the term "precast concrete" refers to cement concrete, which uses cement as the cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a specific ratio, and is obtained through mixing. Currently, precast concrete components often require strength testing before use.

[0003] In related technologies, patent application number CN202221207129.6 discloses a concrete precast component strength testing device, including a testing platform and four support legs fixedly connected to the bottom of the testing platform. Fixed plates are fixedly connected to both sides of the bottom of the testing platform, and the two fixed plates are rotatably connected by a bidirectional screw. One end of the bidirectional screw is connected to the output shaft of a drive motor. Connecting rods that pass through slots through the testing platform are fixedly connected to the tops of the two threaded pairs, and clamping components are fixedly connected to the tops of the two connecting rods. This facilitates clamping and fixing of the precast component, improving its stability and preventing displacement during testing. However, this device lacks a corresponding protective structure during strength testing. Concrete blocks may break during the testing process, easily causing debris to scatter and injure testing personnel, posing a safety hazard. Therefore, we propose a concrete precast component testing device.

[0004] The information disclosed in this background section is only for understanding the background technology of the inventive concept, and therefore may include information that does not constitute prior art. Utility Model Content

A pressure sensor 14 is connected to the lower output end of the electric actuator 6. A testing head 15 is connected to the lower end of the pressure sensor 14. The testing platform 8 is welded and fixed to the upper end of the mounting plate 1 below the testing head 15. A rotating stud 22 is rotatably installed inside the testing platform 8. The left side of the rotating stud 22 is rotatably installed inside the testing platform 8, and the right side of the rotating stud 22 penetrates through the testing platform 8. The rotating stud 22 includes two sets of threaded segments in opposite directions. A mounting block is threadedly engaged on the side of the rotating stud 22. A movable [feature / feature] is welded to the upper end of the mounting block. A threaded rod 23 is threaded through the upper end of the movable plate 18, and the threaded rod 23 is threadedly engaged with the wall surface of the movable plate 18. A pressure plate 24 is fixedly installed at the lower end of the threaded rod 23, and a rotating plate 20 is welded to the upper end of the threaded rod 23. A fastening nut 25 is provided on the side of the threaded rod 23. A movable groove 19 is opened at the corresponding position of the mounting block at the upper end of the testing table 8. A through groove is opened at the center of the mounting plate 1. A protective cover 9 is movably installed in the through groove. Rotating the stud 22 rotates the mounting block, which moves the mounting block and adjusts the distance between the mounting block and the movable plate 18. This allows for the clamping and fixing of precast concrete components of different sizes. The protective cover 9 can effectively prevent the concrete test block from breaking and causing debris to splatter during the testing process, thus ensuring the safety of the testing process.

[0024] In specific implementation of the embodiments of this utility model, such as Figure 1 , 3 As shown, the lower end of the protective cover 9 is integrally formed with a guide sleeve 10, and the lower end of the guide sleeve 10 is connected to a collection box 11. The front end of the collection box 11 is detachably installed with a discharge plate 17. The lower end of the mounting plate 1 is symmetrically and vertically fixed with support columns 2 on the left and right sides. A support base plate 3 is horizontally welded and fixed between the two support columns 2. The upper end of the support base plate 3 is symmetrically and vertically installed with telescopic support columns 12. The cooperation between the guide sleeve 10 and the collection box 11 facilitates the collection of debris generated by the concrete test block, reducing the workload of manual cleaning. The protective cover 9 can be raised and lowered to facilitate the clamping and fixing of the precast concrete components.

[0025] In specific implementation of the embodiments of this utility model, such as Figure 1 , 4 As shown, a support block 13 is fixedly connected to the upper end of the telescopic support column 12. One side of the support block 13 is welded and fixed to the lower side of the protective cover 9. Through slots are opened on the left and right sides of the protective cover 9 at corresponding positions on the testing table 8. A slot 16 is opened in the through slot of the protective cover 9. A baffle is installed in the slot 16. The through slots prevent the testing table 8 from interfering with the movement of the protective cover 9. The baffle in the slot 16 protects the left and right sides of the testing table 8 and improves the protection performance.

[0026] In specific implementation of the embodiments of this utility model, such as Figure 1 , 2 As shown, a battery 7 is installed on the upper left side of the mounting plate 1, a controller 4 is installed on the upper right side of the mounting plate 1, a throttle 21 is installed on the right side of the rotating stud 22, and a fastening nut 25 is provided on the side of the rotating stud 22.

[0027] In this embodiment, all components are general standard parts or parts known to those skilled in the art. Their structures and connection principles are known to those skilled in the art through technical manuals or conventional experimental methods. The precast concrete component to be tested is placed on the testing platform 8. According to the size of the precast component, the position of the mounting block is adjusted by rotating the handle on the right side of the stud 22. Since the stud 22 contains two sets of threaded segments in opposite directions, the mounting blocks on both sides will move relative to or towards each other when rotated, thereby adjusting the distance between the movable plates 18 so as to clamp and fix precast components of different sizes. After adjustment, the stud 22 is locked with the fastening nut 25 to prevent it from rotating accidentally during the testing process. The rotating plate 20 at the upper end of the threaded rod 23 is rotated, causing the pressure plate 24 to drop, further fixing the precast component firmly on the testing platform 8. After ensuring that the precast component is firmly fixed, the protective cover 9 is raised and adjusted to an appropriate height using the telescopic support column 12. The protective cover 9 effectively blocks debris that may fly out due to the breakage of the precast component, ensuring the safety of the operators. The bottom of the protective cover 9 is equipped with a guide sleeve 10, which is connected to the collection box 11 to collect the debris generated during the testing process for easy subsequent cleaning. The controller 4 starts the electric push rod 6, which pushes the pressure sensor 14 and the detection head 15 connected below it downward to apply a predetermined pressure to the concrete precast component. The pressure sensor 14 monitors and records the force value acting on the precast component in real time. This data can be used to evaluate the quality and strength characteristics of the precast component. After the test is completed, the electric push rod 6 is retracted to release the pressure on the precast component, the protective cover 9 is lowered, the tested concrete precast component is removed, the waste in the collection box 11 is emptied, and preparation is made for the next test.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
