DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0022] Please refer to Figure 1-2As shown in the figure, a concrete strength detection device convenient for movement includes a main board 1. A rotation component is installed on the top side of the main board 1. The rotation component includes a mounting frame 2. A rotating shaft 3 is rotatably installed through the inside of the mounting frame 2. A handle 4 is installed on one side of the rotating shaft 3. Four connecting rods 5 are equidistantly installed on the outer wall of the rotating shaft 3. One end of each connecting rod 5 is fixedly installed with a pressure head 6. The sizes and shapes of the pressure heads 6 are all different. A limiting hole 9 is penetrated and opened between the two sides of the mounting frame 2. A through hole 10 is opened inside the connecting rod 5. A limiting rod 7 is slidably installed inside the limiting hole 9 and through the through hole 10. A limiting block 8 is fixedly connected to one side of the limiting rod 7. A tension spring 11 is fixedly connected between the limiting block 8 and the mounting frame 2. A fixing frame 12 is fixedly installed on the top side of the main board 1. A cylinder 13 is installed on the top side of the fixing frame 12. A control panel 31 is installed on one side of the fixing frame 12. During work, in actual application, it cannot meet the requirements of different concrete strength detections. However, in the prior art, the rotation use of the pressure head 6 cannot be realized, resulting in a narrow application range of the device. First, a concrete block to be detected is placed on the surface of the main board 1 by an external manipulator and is located directly below the pressure head 6. When selecting a suitable pressure head 6 according to the concrete strength to be detected, by pulling the limiting block 8, the limiting rod 7 slides along the through hole 10 and the limiting hole 9 under the action of the tension spring 11 and disengages from the through hole 10. Subsequently, the handle 4 is rotated, so that the rotating shaft 3 rotates inside the mounting frame 2, thereby driving the connecting rod 5 and the pressure head 6 to rotate. When the required pressure head 6 rotates to the appropriate position, by releasing the limiting block 8, the position of the currently selected pressure head 6 is fixed under the action of the tension spring 11. Subsequently, the cylinder 13 is started through the control panel 31. The acting end of the cylinder 13 pushes the mounting frame 2 to descend, so that the selected pressure head 6 contacts the surface of the concrete to be detected. At this time, the cylinder 13 continues to apply pressure to detect the strength of the concrete through the pressure head 6. During the detection process, the control panel 31 will display the pressure applied by the pressure head 6 and the deformation condition of the concrete in real time. It can be judged whether the strength of the concrete meets the requirements according to these data. After the detection is completed, the cylinder 13 will drive the mounting frame 2 to rise, so that the pressure head 6 leaves the surface of the concrete and waits for the next detection, realizing the rotation use of multiple pressure heads 6 with different sizes and shapes and being able to meet the requirements of different concrete strength detections.

[0023] Please refer to Figure 1 、 3As shown, two sets of two support plates 14 are symmetrically installed on the top side of the main board 1. A threaded rod 16 and a guide rod 17 are respectively rotatably installed and fixedly installed between each set of support plates 14. A driving motor 15 is installed on one side of the support plate 14. One end of the threaded rod 16 is cooperatively connected to the output end of the driving motor 15. An active block 18 is movably installed on the outer walls of the threaded rod 16 and the guide rod 17 in cooperation. A push plate 19 is installed on the bottom side of the active block 18. Five fixing rods 20 are equidistantly and fixedly installed on one side of the push plate 19. One end of the fixing rod 20 is fixedly connected to a scraping plate 21. Both the scraping plate 21 and the push plate 19 are arranged in contact with the surface of the main board 1;

[0024] Sliding rails 27 are symmetrically installed on the bottom side of the main board 1. Sliders 28 are slidably installed inside the sliding rails 27. A collection box 29 is fixed between the sliders 28. A handle 30 is fixed on one side of the collection box 29. A blanking groove 32 is formed inside one end of the main board 1. The collection box 29 is located directly below the blanking groove 32; During operation, the concrete compressive strength is one of the important performance parameters. Before the concrete is put into use, the strength of the concrete test block needs to be detected by a testing instrument. The unqualified concrete blocks will break and leave residues, affecting the working environment of the testing operation. After the concrete strength test is completed, the driving motor 15 drives the threaded rod 16 to rotate, thereby driving the active block 18 to move along the axial directions of the threaded rod 16 and the guide rod 17. The push plate 19 and the scraping plate 21 on its bottom side will also move accordingly. The push plate 19 clears the large particle residues, and the scraping plate 21 scrapes off the remaining ash residues. The scraped concrete residues will fall into the collection box 29 along the blanking groove 32. At the same time, when it is necessary to clean the collection box 29, the user only needs to hold the handle 30 and pull the collection box 29 out of the sliding rail 27. After cleaning, the collection box 29 is pushed back to its original position to prepare for the next collection work, realizing the cleaning of the main board 1 and the centralized collection of the residues after cleaning.

[0025] Please refer to Figure 1 、 4As shown, support legs 22 are fixedly installed at the four corners of the main board 1. One side of each support leg 22 is equipped with a telescopic rod 23. The telescopic rod 23 is fixed to the bottom side of the main board 1. Inside the acting end of the telescopic rod 23, a rotating shaft 24 is rotatably installed. At the bottom side of the rotating shaft 24, a support frame 25 is installed. Inside the support frame 25, a wheel 26 is installed by means of a pin shaft; during operation, it changes as the project progresses. Therefore, the concrete strength testing equipment needs to have sufficient portability to be easily transferred between different working areas. When the device is in a stationary state for concrete strength testing, the telescopic rod 23 is in a shortened state, so that the support leg 22 contacts the ground, providing stable support for the device. When it is necessary to move the device to a new working site, the telescopic rod 23 is extended, the support leg 22 is gradually lifted, and at the same time the wheel 26 gradually contacts the ground. After the wheel 26 is completely in contact with the ground, it is convenient to push the device to move.

[0026] Working principle: When the device is in a stationary state for concrete strength testing, the telescopic rod 23 is in a shortened state, so that the support leg 22 contacts the ground, providing stable support for the device. When it is necessary to move the device to a new working site, the telescopic rod 23 is extended, the support leg 22 is gradually lifted, and at the same time the wheel 26 gradually contacts the ground. After the wheel 26 is completely in contact with the ground, it is convenient to push the device to move;

[0027] First, the concrete block to be tested is placed on the surface of the main board 1 by an external manipulator and is directly below the indenter 6. When selecting a suitable indenter 6 according to the concrete strength to be tested, by pulling the limit block 8, the limit rod 7 slides along the through hole 10 and the limit hole 9 under the action of the tension spring 11 and disengages from the control of the through hole 10. Subsequently, the handle 4 is rotated, so that the rotating shaft 3 rotates inside the mounting frame 2, thereby driving the connecting rod 5 and the indenter 6 to rotate. When the required indenter 6 rotates to the appropriate position, by releasing the limit block 8, the position of the currently selected indenter 6 is fixed under the action of the tension spring 11. Subsequently, the cylinder 13 is started through the control panel 31. The acting end of the cylinder 13 pushes the mounting frame 2 to descend, so that the selected indenter 6 contacts the surface of the concrete to be tested. At this time, the cylinder 13 continues to apply pressure, and the strength of the concrete is tested through the indenter 6. During the testing process, the control panel 31 will display the pressure applied by the indenter 6 and the deformation of the concrete in real time. It is possible to judge whether the strength of the concrete meets the requirements based on these data, realizing the rotation and use of multiple indenters 6 of different sizes and shapes, and being able to meet the needs of different concrete strength tests;

[0028] After the concrete strength test is completed, the drive motor 15 drives the threaded rod 16 to rotate, thereby driving the movable block 18 to move along the axial directions of the threaded rod 16 and the guide rod 17. The push plate 19 and the scraper 21 at its bottom side will also move accordingly. The push plate 19 clears the large particle residues, and the scraper 21 scrapes off the remaining ash residues. The scraped concrete residues will fall into the final collection box 29 along the blanking chute 32. At the same time, when it is necessary to clean the collection box 29, the user only needs to hold the handle 30 and pull the collection box 29 out of the slide rail 27. After cleaning, push the collection box 29 back to its original position to prepare for the next collection work, realizing the cleaning of the main board 1 and the centralized collection of the residues after cleaning.
