[0002] Concrete core sampling devices are mainly used for core sampling of cement concrete, asphalt concrete, and limestone foundations in highways, airports, ports, docks, dams, etc., for compressive and flexural tests. As a new type of building drilling machinery, it drills holes in concrete structures or components, then extracts concrete core samples through a core sampling rod, prepares concrete strength specimens, and determines the strength of the concrete core samples. This is used to verify and validate the concrete strength of buildings, or as a key quality indicator for evaluating structures.
[0003] Existing concrete coring structures move vertically downwards, thus only allowing operations on horizontal surfaces. They cannot sample inclined surfaces or walls, resulting in limited applicability of existing concrete coring devices. Furthermore, existing coring structures are inconvenient to move, making them impractical.
[0004] Based on this, an auxiliary adjustment structure for concrete core sampling testing is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0023] In one embodiment, such as Figures 1-3 As shown, an auxiliary adjustment structure for concrete core sampling testing includes a support frame 1 with several casters 2 at its bottom. Symmetrical support plates 3 are mounted on the support frame 1, and load-bearing plates 4 are positioned between the support plates 3. The bottom of the load-bearing plates 4 is rotatably connected to the support plates 3 via hinges 5. A first connecting plate 6 is located on the outer side of the top of the load-bearing plates 4, and a first motor 7 is mounted on the first connecting plate 6. A lead screw 8 is mounted at the output end of the first motor 7, and a lifting mechanism is mounted on the lead screw 8. A core sampling testing mechanism is located on one side of the lifting mechanism, and an adjustment mechanism is located on the inner side of the load-bearing plates 4. The load-bearing plates 4 can rotate freely around the hinges 5. Starting the first motor 7 drives the lead screw 8 to rotate, causing the lifting mechanism to adjust its height, thus adjusting the height of the core sampling mechanism. Core sampling testing is performed through the core sampling mechanism. The angle of the load-bearing plates 4 can be adjusted via the adjustment mechanism, thereby changing the core sampling angle of the core sampling mechanism. This structure is suitable for various scenarios and improves practicality.
[0024] In one embodiment, such as Figure 1 As shown, the lifting mechanism includes a movable block 9, which is threadedly connected to the lead screw 8. During the rotation of the lead screw 8, the movable block 9 can be driven to move up and down.
[0025] In one embodiment, such as Figure 1 As shown, the load-bearing plate 4 has guide grooves 12 on both sides, and the moving block 9 has connecting shafts 10 on both sides. Rollers 11 are rotatably connected to the connecting shafts 10. The rollers 11 roll in the guide grooves 12. The rollers 11 and the guide grooves 12 limit each other, which can restrict the rotation of the moving block 9 and improve the stability of the up and down movement.
[0026] In one embodiment, such as Figure 3As shown, a fixed plate 13 is provided on the outside of the movable block 9, and a first rotating shaft 14 is rotatably connected to the bottom end of the fixed plate 13. The first rotating shaft 14 can rotate freely.
[0027] In one embodiment, such as Figure 3 As shown, the core sampling detection mechanism includes a core sampling tube 15, which is fixedly connected to the bottom end of the first rotating shaft 14. A first gear 16 is provided on the first rotating shaft 14 above the core sampling tube 15, and the core sampling tube 15 can rotate synchronously with the first rotating shaft 14.
[0028] In one embodiment, such as Figure 3 As shown, a second connecting plate 17 is provided on one side of the fixed plate 13, and a second motor 18 is provided on the second connecting plate 17. A second rotating shaft 19 is provided at the output end of the second motor 18, and a second gear 20 is provided at the end of the second rotating shaft 19. The second gear 20 meshes with the first gear 16. When the second motor 18 is started, it drives the second gear 20 to rotate. Through the meshing of the second gear 20 with the first gear 16, the first rotating shaft 14 rotates synchronously, thereby driving the core drilling tube 15 to rotate and perform core sampling.
[0029] In one embodiment, such as Figure 2 As shown, a guide rail 21 is provided on the inner side of the load-bearing plate 4, and a slider 22 is provided on the outer side of the guide rail 21. A guide block 23 is provided on the slider 22, and the guide block 23 is slidably connected inside the guide rail 21. A fastening screw 27 is provided on the slider 22. Through the slidable connection between the guide block 23 and the guide rail 21, the slider 22 can slide up and down on the guide rail 21. Rotating the fastening screw 27 can limit the slider 22 and fix it in the current position.
[0030] In one embodiment, such as Figure 2 As shown, the adjustment mechanism includes a first rotating rod 24, which is symmetrically arranged on both sides of the slider 22. A second rotating rod 25 is arranged on the inner side of the support frame 1, and the first rotating rod 24 and the second rotating rod 25 are rotatably connected by a connecting rod 26. The slider 22 is adjusted on the guide rail 21, thereby changing the angle of the load-bearing plate 4 and driving the core drilling tube 15 to adjust the core angle. It is suitable for various scenarios and improves practicality.
[0031] Working principle: When concrete sampling is required, push the support frame 1 to the appropriate position, move the slider 22 to adjust its position on the guide rail 21, and rotate the fastening screw 27 to limit the slider 22 and fix it in the current position. If the angle of the load-bearing plate 4 is changed as needed, the core drilling tube 15 will be driven to adjust the core sampling angle. It can be applied to various scenarios such as inclined ground and walls, greatly improving its practicality. Start the second motor 18 to drive the second gear 20 to rotate. Through the meshing of the second gear 20 and the first gear 16, the first rotating shaft 14 will rotate synchronously. The core drilling tube 15 will rotate synchronously with the first rotating shaft 14, thereby driving the core drilling tube 15 to rotate. Start the first motor 7 to drive the lead screw 8 to rotate. During the rotation of the lead screw 8, the moving block 9 can be driven to move up and down, thereby driving the core drilling tube 15 to move up and down to perform core sampling.
