Description

Technical Field

[0001] This utility model relates to the technical field of concrete testing equipment, specifically a multifunctional strength tester for concrete engineering. Background Technology

[0002] Concrete strength testing is crucial. It directly relates to the safety and durability of building structures and is a key link in ensuring project quality. Accurate concrete strength testing can promptly identify areas that do not meet strength standards, preventing serious accidents such as structural cracking and collapse caused by insufficient strength. At the same time, the test results provide a scientific basis for subsequent construction adjustments and quality acceptance, ensuring that the building meets design requirements and can be safely put into use and operate stably for a long period.

[0003] Patent document CN213397940U discloses a multifunctional strength testing instrument for concrete engineering. Its structure includes a workbench, support frame, housing, inner cavity, door, control panel, display screen, buttons, power cord, electric push rod, pressure block, and quick clamping device. This invention features a quick clamping device inside the inner cavity. A drive mechanism rotates a drive gear, which in turn rotates a driven gear that drives a lead screw. This lead screw, through a threaded groove, moves a moving disc downwards, fixing the concrete sample within the placement groove, preventing it from easily loosening during use. A tray inside the inner cavity allows debris generated during pressure testing to fall onto the tray for easy cleaning, providing convenience for the user. However, this patent still has the following problems in practical use: This strength tester uses a tray to clean up broken debris, but removing the tray when it is full of concrete is inconvenient, making it difficult to use. Furthermore, the lifting and moving tray is used to position the concrete, which can affect the strength test. The moving tray is also prone to damage when the concrete breaks, thus making the tester less practical.

The current strength tester achieves the effect of cleaning broken residue by setting a tray, but it is inconvenient to remove the tray when it is full of concrete, which makes it inconvenient to use. In addition, the positioning of the concrete by the lifting and moving tray can affect the concrete strength test, and the moving tray can be easily damaged when the concrete breaks. Therefore, the practicality of the strength tester is poor.

The testing platform 7 is fixedly installed in the middle of the bottom surface of the inner wall of the testing chamber 4. The bottom surface of the cylinder 3 overlaps with the top surface of the testing platform 7, and the clearance groove 6 is rotatably connected to the outer side of the testing platform 7. The shrinkage groove 8 is symmetrically opened on both sides of the lower end of the testing platform 7. The sliding frame 9 and the limiting plate 10 are symmetrically arranged at both ends of the limiting screw 11. The middle of the limiting plate 10 is inserted into the side of the rotating frame 5 near the clearance groove 6. The limiting screw 11 is set as a bidirectional screw. One end of the limiting screw 11 passes through the testing platform 7 and is fixedly connected to the output end of the limiting motor 12. By setting the rotating frame 5 on the outer side of the testing platform 7 and driving the extension and retraction of the limiting plate 10 through the sliding frame 9, the limiting plate 10 can limit and separate the rotating frame 5, thereby facilitating the discharge of concrete from the discharge port 21 by rotating the rotating frame 5, making the removal of concrete more convenient and faster.

[0018] The testing platform 7 has a rotating groove 14 on one side of its upper end. A support frame 13 is rotatably connected to the middle of the rotating groove 14. An adjusting support rod 16 is slidably connected to one side of the bottom of the support frame 13. A support screw 15 is threaded to the middle of the lower end of the adjusting support rod 16. A transmission bevel gear 18 is fixedly connected to the middle of the support screw 15. A driven bevel gear 19 is meshed with one side of the transmission bevel gear 18. A driven screw 20 is fixedly connected to one side of the driven bevel gear 19. The support frame 13, rotating groove 14, and adjusting support rod 16 are arranged in four groups, and the four groups of support frames 13, rotating grooves 14, and adjusting support rods 16 are respectively arranged in the middle of the top surface of the testing platform 7. Rod 15 is configured as a bidirectional screw, with the support screw 15 rotatably connected to the middle of the rotating groove 14, and one side of the support screw 15 fixedly connected to the output end of the support motor 17; driven bevel gear 19 and driven screw 20 are symmetrically arranged on both sides of the transmission bevel gear 18, and the two sets of driven bevel gears 19 and driven screw 20 are respectively threadedly connected to the adjusting support rod 16 at the end away from the support screw 15; by setting a support frame 13 at the top of the testing table 7, and by rotating the support screw 15 and driven screw 20 respectively, the support frame 13 can be extended and retracted, which facilitates the support effect on the concrete, thereby facilitating the stable placement of the concrete and the testing of the concrete.

[0019] Working principle: When using this multi-functional strength tester for concrete engineering, firstly, the support motor 17 drives the support screw 15 and the transmission bevel gear 18 to rotate, which in turn drives the driven bevel gear 19 to rotate. This causes the support screw 15 and the driven screw 20 to drive the adjusting support rod 16 to push the support frame 13 to rotate in the rotating groove 14, so that the support frame 13 protrudes from the top surface of the test table 7.

[0020] Next, the concrete to be tested is placed in the middle of the support frame 13 at the top of the testing platform 7 in the strength testing box 1, and the cylinder 3 is lowered by the control panel 2 to squeeze the concrete, thereby realizing the test of the concrete strength. The broken concrete falls on the upper end of the rotating frame 5.

[0021] Finally, by controlling the limit motor 12 to drive the limit screw 11 to rotate, the limit screw 11 slides and contracts in the shrinkage groove 8 through the sliding frame 9, thereby causing the sliding frame 9 to drive the limit plate 10 to separate from the rotating frame 5. Then the rotating frame 5 rotates on the outside of the detection table 7 through the relief groove 6, thereby causing the concrete to slide down the inclined rotating frame 5. Then the concrete is discharged from the detection chamber 4 through the discharge port 21.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
