[0002] As one of the most common testing items in engineering projects, concrete compressive strength testing is in great demand in actual testing. However, most domestic concrete compressive strength testing currently relies heavily on manual labor. Manual operations are required in all aspects of the concrete compressive strength testing process, including sample information entry, sample storage and transportation, sample strength testing, post-test cleaning, data collection, and comprehensive processing.

[0003] The prior art discloses a gripping mechanism for concrete compression test blocks, with publication number (CN212331060U). The mechanism comprises a concave main frame, to which an adjustment structure is bolted; an electric telescopic rod is bolted to the top end of the inner wall of the main frame, and a drive block is bolted to the end of the electric telescopic rod. This prior art grips the test block by clamping it with two clamping plates. However, the clamping force is difficult to control, which can easily damage the test block and affect the test results. Furthermore, the mechanism lacks a cleaning mechanism, requiring manual cleaning, which is time-consuming, labor-intensive, and inefficient.

[0004] Therefore, the present invention provides a grabbing mechanism for concrete test block experiments to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] Reference Figures 1-4 As shown, this embodiment provides a gripping mechanism for concrete specimen experiments, including a box body 1, the bottom of the box body 1 is open, and a splint 2 is symmetrically slidably connected inside the box body 1, the bottom of the splint 2 extends out of the box body 1, and the side wall of the splint 2 is fixedly connected to the output end of the multi-stage telescopic rod 11, and the side of the multi-stage telescopic rod 11 away from the splint 2 is fixedly connected to the inner wall of the box body 1, and the bottom of the splint 2 is fixedly connected to a bearing base plate 8, and the two bearing base plates 8 are staggered. A groove 3 is provided on the side of the splint 2 away from the bearing base plate 8, and a rotating plate 4 is rotatably connected in the groove 3. A first cleaning roller 5 and a second cleaning roller 6 are respectively installed on the rotating plate 4, and the first cleaning roller 5 and the second cleaning roller 6 are arranged vertically.

[0023] When in use, the box body 1 is connected to the external transfer equipment to drive the movement of the box body 1 as a whole. The multi-stage telescopic rod 11 is an electric telescopic rod. By controlling the extension of the two multi-stage telescopic rods 11, the two splints 2 are driven to move toward each other to clamp the test block. At the same time, the bearing base 8 at the bottom of the splint 2 supports the test block. The clamping force between the two splints 2 does not need to be too large, as long as the stability of the test block is guaranteed. The bearing base 8 supports the test block, which is convenient for transportation without damaging the test block, thereby improving the test accuracy; when the box body 1 is transferred to the test bench by the external transfer equipment, the rotating plate 4 rotates out of the groove 3 until it is perpendicular to the splint 2, and then the box body 1 is moved back and forth, so that the first cleaning roller 5 and the second cleaning roller 6 on the rotating plate 4 clean the surface of the test bench (the first cleaning roller 5 and the second cleaning roller 6 are respectively equipped with brushes), saving manpower and improving work efficiency; the setting of the groove 3 facilitates the storage of the rotating plate 4 when not in use, saving space. The utility model has the advantages of simple structure, convenient use, and can complete the transportation work without damaging the test block, has high precision, and has a cleaning function, thereby greatly improving work efficiency.

[0024] In a further optimized solution, a motor 12 is embedded in the rotating plate 4. The output shaft of the motor 12 is fixedly connected to a first transmission wheel 13. The first transmission wheel 13 is connected to a second transmission wheel 15 via a belt 14. The second transmission wheel 15 is fixedly mounted to the first cleaning roller 5. The motor 12 drives the first transmission wheel 13 to rotate. The first transmission wheel 13 drives the second transmission wheel 15 to rotate via the belt 14. The second transmission wheel 15 drives the first cleaning roller 5 to rotate, thereby facilitating the cleaning of the test bench.

[0025] In a further optimization scheme, a connecting shaft 16 is fixedly connected to the first cleaning roller 5. Both ends of the connecting shaft 16 extend into the rotating plate 4 and are rotatably connected to the rotating plate 4. One end of the connecting shaft 16 is fixedly connected to the second transmission wheel 15, and the other end of the connecting shaft 16 is in driving connection with the second cleaning roller 6. The rotation of the second transmission wheel 15 drives the connecting shaft 16 to rotate, and the connecting shaft 16 drives the first cleaning roller 5 to rotate. The connecting shaft 16 also drives the second cleaning roller 6 to rotate, thereby achieving cleaning work in different directions and improving cleaning efficiency.

[0026] In a further optimized solution, a central shaft 19 is fixedly connected to the second cleaning roller 6, which is rotatably connected to the rotating plate 4. A second bevel gear 18 is fixedly connected to the end of the central shaft 19. The second bevel gear 18 meshes with a first bevel gear 17. The first bevel gear 17 is fixedly connected to the end of the connecting shaft 16 away from the second transmission wheel 15. The rotation of the connecting shaft 16 drives the first bevel gear 17 to rotate, the first bevel gear 17 drives the second bevel gear 18 to rotate, the second bevel gear 18 drives the central shaft 19 to rotate, and the central shaft 19 drives the second cleaning roller 6 to rotate, thereby achieving cleaning work in different directions.

[0027] As a further optimization, a hydraulic rod 20 is hingedly connected to the inner wall of the groove 3, and the output end of the hydraulic rod 20 is hingedly connected to the side wall of the rotating plate 4. The extension of the hydraulic rod 20 can drive the rotating plate 4 to rotate. After the rotating plate 4 rotates out of the groove 3, the first cleaning roller 5 and the second cleaning roller 6 contact the surface of the test bench, facilitating the cleaning process.

[0028] Further optimizing scheme, the groove 3 is fixed with a pin 7, the pin 7 passes through the bottom of the rotating plate 4 and is rotatably connected to the rotating plate 4. The setting of the pin 7 improves the rotation performance of the rotating plate 4 and facilitates the completion of the rotation action.

[0029] To further optimize the solution, a tilting head 9 is fixed to one end of the bearing base plate 8 away from the clamping plate 2. The setting of the tilting head 9 facilitates the bearing base plate 8 to lift the test block and improves the smoothness when clamping the test block.

[0030] In a further optimized solution, a plurality of limit rods 10 are fixed vertically in the box body 1, and the limit rods 10 pass through the clamping plate 2 and are slidably connected to the clamping plate 2. The setting of the limit rods 10 limits the clamping plate 2, prevents deviation during the sliding process, and improves stability during operation.
