[0028] The utility model will be described in detail in combination with the specific embodiments shown in the drawings. However, these embodiments do not limit the utility model, and the changes in structure, method or function made by those skilled in the art based on these embodiments are all included in the protection scope of the utility model.

[0029] As shown in Figures 1-5 The embodiment proposes a road and bridge concrete strength detection device, which comprises:

[0030] The substrate 2 is provided with a rotatable center plate 3 above the substrate 2, bearings can be provided between the substrate 2 and the center plate 3 for the rotation of the center plate 3, and at least three sets of clamping assemblies for clamping the concrete test block 1 are provided on the center plate 3. The clamping assembly comprises a connecting rod 4 hinged to the center plate 3, the other end of the connecting rod 4 is hinged to a pushing block 5, a guide block 7 is further connected on the substrate 2, and a sliding block 6 slides along the guide block 7, the sliding block 6 is connected to one end of the pushing block 5; a protective plate 8 is detachably provided above the center plate 3, and the protective plate 8 covers the pushing block 5 and the sliding block 6, the protective plate is provided with an avoiding opening 81 corresponding to the pushing block 5, and the pushing block 5 linearly moves in the avoiding opening 81. The driving assembly is connected with one of the sliding blocks 6, drives the sliding block 6 to slide along the guide block 7, drives the center plate 3 to rotate to move the pushing block 5 to the center. The top plate 9 is connected above the substrate 2, and the hydraulic assembly for pressing the concrete test block 1 above the substrate 2 is connected above the top plate 9.

[0031] In the process of concrete strength detection, it is usually required to press in the middle of the test block, because the position in the middle can best represent the uniformity of the whole test block. Pressing the edge or other non-central position may cause uneven stress distribution, test result deviation, test block damage mode change, and inconsistent stress points for comparison detection.

[0032] Based on the above problems, a new concrete strength detection device is researched, which realizes the self-centering of the concrete test block 1 through the synchronous centering movement of the three pushing blocks 5. Specifically, one of the sliding blocks 6 is driven by the driving assembly to slide to the center, and in the sliding process, the center plate 3 is rotated by the connecting rod 4, so that the other pushing blocks 5 are moved to the center by the pull rod, and the concrete test block 1 is moved to the center position, and then the strength test is carried out by the hydraulic assembly.

[0033] In some embodiments, the driving assembly comprises a driving block 10 connected to the substrate 2, a threaded hole is formed in the driving block 10, a threaded rod 11 is threadedly connected to the threaded hole, one end of the threaded rod 11 penetrates through the threaded hole of the driving block 10 and is rotatably connected to the sliding block 6, a bearing is arranged between the sliding block 6 and the threaded rod 11 to prevent the threaded rod 11 from rotating and driving the sliding block 6 to rotate, and a rotating handle 12 is connected to the other end of the threaded rod 11. Manual rotation allows the operator to adjust the clamping force according to the needs, which is suitable for test blocks of different sizes and shapes, and can effectively prevent damage to the test block caused by improper clamping.

[0034] In some embodiments, the hydraulic assembly includes a hydraulic cylinder 13 arranged above the top plate 9, a hydraulic rod 14 connected to the hydraulic cylinder 13, a hydraulic disc 15 connected to the hydraulic rod 14 after the hydraulic rod 14 freely penetrates the top plate 9, a pressure sensor 16 installed on the hydraulic rod 14, and the pressure sensor 16 located above the hydraulic disc 15. By monitoring and measuring the pressure value applied to the test block in real time through the pressure sensor 16, and cooperating with the pressing of the hydraulic disc 15, the test block can be uniformly pressed, so as to accurately detect the strength of the concrete test block 1.

[0035] In some embodiments, four groups of connecting columns are fixedly connected at the corners between the top plate 9 and the base plate 2, protective covers 17 are arranged between adjacent connecting columns, and a protective door 18 that can be opened and closed is arranged between one of the connecting columns. Further, the protective cover 17 and the protective door 18 are both made of transparent acrylic plate material. By providing stable support through the connecting columns and using acrylic plate material to ensure the transparency of the structure, the internal operation can be easily observed, and the protective function is good, which can effectively prevent external interference and internal test block splashing. Not only does it improve the safety of the device, but it also enhances the convenience and visibility of the operation.

[0036] In some embodiments, the guide block 7 is in a rectangular configuration, a convex groove is formed in the guide block 7, and the sliding block 6 is slidingly arranged in the convex groove. This structure ensures the linearity and stability of the movement of the sliding block 6, reduces the deviation and vibration during movement, prevents derailment, and enhances safety and reliability.

[0037] In some embodiments, the clamping surface of the pushing block 5 has a tooth section; the friction between the pushing block 5 and the concrete test block 1 is enhanced, and a more secure fixing effect is provided.

[0038] In some embodiments, at least two groups of support columns 20 are fixed on the base plate 2, at least two groups of sleeves 19 are arranged at the bottom of the protective plate 8, and the support columns 20 are correspondingly inserted into the sleeves 19. The protective plate 8 is a platform specially designed for placing the concrete test block 1, and the protective plate 8 is supported by the limiting columns. When detecting the strength of the concrete, damage to the key components such as the sliding block 6, the connecting rod 4, and the guide block 7 caused by splashing debris can be effectively avoided. At the same time, it is convenient to disassemble and clean and maintain the area below.

[0039] In some embodiments, a storage cabinet 21 is fixedly connected below the base plate 2. This design has both practicality and functionality. On the one hand, the storage cabinet 21 is used for storing tools, materials, and other related items, providing a storage space that helps to keep the work area clean and efficient. On the other hand, the storage cabinet 21 raises the height of the base plate 2, making the height of the base plate 2 convenient for operators to perform various operations, improving the convenience and comfort of the operation, thereby improving the overall work efficiency and operation safety.

[0040] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
