[0002] With the development of the construction industry, concrete precast components are widely used in various construction projects. To ensure the project quality, it is crucial to accurately detect the strength of concrete precast components. The strength detector for concrete precast components is a device designed to meet this requirement, which can test various mechanical properties of concrete precast components, such as compressive strength, flexural strength, and impact resistance.

[0003] In the process of detecting the strength of concrete precast components, in some cases where the strength of the concrete precast components is unqualified and they break, concrete particles will stay on the tabletop of the detector. If the concrete particles cannot be cleaned in time, it will affect the subsequent detection of concrete precast components. During the use of the existing strength detectors for concrete precast components, generally, the concrete precast components are directly placed on the tabletop of the detector. During the detection process, the concrete precast components will displace, thus affecting the detection results.

[0025] Please refer to Figures 1-8, the present utility model provides a technical solution: a strength detector for concrete precast components, including a base 1, a support block 2, a motor 3, a hydraulic press 7 and an opening and closing door 16. A support block 2 is fixed on the top of the base 1, and a motor 3 is arranged on the side of the support block 2. The motor 3 is connected with a first threaded rod 301, and the first threaded rod 301 penetrates through two movable plates 5. Two movable slots 4 are opened on the support block 2. A hydraulic press 7 is arranged on the top of the support block 2, and the hydraulic press 7 is connected with a detection plate 9 through a hydraulic rod 8. Two first covers 10 are arranged on the upper surface of the base 1, and a support plate 12 is arranged under the first covers 10 on the base 1. Extension blocks 13 are arranged on both sides of the base 1, and fixed blocks 14 are arranged on both sides of the extension blocks 13. A collection box 15 is arranged inside the base 1, and an opening and closing door 16 is arranged at the position of the collection box 15 on the base 1.

[0026] The two movable plates 5 are installed on the support block 2 through the movable slots 4, and the movable plates 5 are slidably connected with the support block 2. The thread directions at both ends of the first threaded rod 301 are opposite, and the two movable plates 5 are respectively arranged at both ends of the first threaded rod 301. The first threaded rod 301 is located in the movable slot 4, and the first threaded rod 301 is connected with the support block 2 by a bearing. By rotating the first threaded rod 301, the two movable plates 5 can be moved to facilitate the limitation of concrete precast components of different sizes.

[0027] A second threaded rod 6 is arranged on the top of the movable plate 5, and the second threaded rod 6 is threadedly connected with the movable plate 5. A pressing block 601 is arranged at the bottom of the second threaded rod 6, and the pressing block 601 is connected with the second threaded rod 6 by a bearing. A chute 501 is opened on the inner side of the movable plate 5, and the pressing block 601 is connected with the movable plate 5 through the chute 501. The pressing block 601 is slidably connected with the movable plate 5. By rotating the second threaded rod 6, the pressing block 601 can be lowered to facilitate the fixation of the concrete precast component.

[0028] The support plate 12 penetrates through the extension block 13 on the same side, and the support plate 12 is slidably connected with the base 1. First empty slots 1301 are opened on both sides of the extension block 13 for the support plate 12, and a first spring 1302 and a top block 1303 are arranged inside the first empty slots 1301. The bottom of the first spring 1302 is fixed at the bottom of the first empty slot 1301, and the top block 1303 is fixed at the top of the first spring 1302. By the rebound of the first spring 1302, the top block 1303 can push out the support plate 12 to facilitate the quick extraction of the support plate 12.

[0029] On the outer side of the extension block 13, fixing blocks 14 are arranged at both ends of the support plate 12. The fixing blocks 14 are provided with second empty slots 1401. Inside the second empty slots 1401, second springs 1402 and clamping blocks 1403 are arranged. The clamping blocks 1403 form a sliding structure with the fixing blocks 14. The support plate 12 can be fixed by the clamping blocks 1403, which facilitates quickly unlocking the fixation of the support plate 12 when the support plate 12 needs to be pulled out.

Then turn on the motor 3 to make the movable plate 5 move along the first threaded rod 301 in the movable slot 4 to perform left and right limit on the concrete precast component. Then rotate the second threaded rod 6 to make the pressing block 601 move downward along the sliding slot 501 to fix the concrete precast component. Then turn on the hydraulic press 7 to make the detection plate 9 move downward through the hydraulic rod 8 and detect the concrete precast component. After the detection is completed, drive the detection plate 9 to rise through the hydraulic rod 8. Then reverse-rotate the second threaded rod 6 to make the pressing block 601 rise. Then drive the first threaded rod 301 to reverse-rotate through the motor 3 to make the two movable plates 5 move outward. Then remove the concrete precast component, and this completes the use of this concrete precast component strength tester.

[0032] When using this concrete precast component strength tester to clean the concrete gravel, first slide the clamping block 1403 to make the clamping block 1403 enter the second empty slot 1401. At the same time, the first spring 1302 in the first empty slot 1301 rebounds, and the top block 1303 jacks up the top of the support plate 12. Then pull out the support plate 12 from the base 1.
