Description

Technical Field

[0001] This utility model relates to the field of concrete crack detection technology, specifically a concrete microcrack detection device. Background Technology

[0002] Cracks are the most common defects or damage in concrete structures. Numerous civil engineering accidents demonstrate that cracks in concrete structures can seriously affect the structural integrity and load-bearing capacity of the project, leading to serious safety hazards. If concrete cracks are not repaired in a timely manner, safety risks will inevitably occur. Therefore, the detection of concrete cracks and the timely implementation of maintenance measures are one of the foundations for ensuring the quality and safety of engineering projects.

[0003] Chinese Utility Model Patent No. CN219757152U discloses a concrete crack detection device, relating to the technical field of concrete crack detection. The device includes a measuring rod with a groove at its top and graduations. Two sliders are movably installed inside the groove. A limit plate is fixedly installed at the top of each slider, and an aiming rod is fixedly installed at the bottom of each slider. Support plates are fixedly installed on the left and right side walls of the measuring rod. In this invention, rotating the threaded rod in different directions allows it to move up and down. Simultaneously, because a bearing is fixedly installed at the bottom of each threaded rod, the corresponding connecting block below each threaded rod does not need to rotate and can move up and down with the threaded rod until it is horizontal, facilitating crack detection.

[0004] Because existing technologies have problems such as difficulty in moving the testing equipment within the testing area due to the varying areas of concrete, difficulty in adjusting the height when testing concrete of different heights, and difficulty in providing stable support for some internal structures, we propose a concrete microcrack detection device to solve the aforementioned problems.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-4An existing concrete microcrack detection device is inconvenient to move within the detection area due to the varying areas of concrete. To address this technical problem, this embodiment discloses the following technical content.

[0026] Wheels 2 are fixedly connected to the four corners of the lower surface of box 1, and handle 3 is fixedly connected to the middle of the lower right side of box 1. Connecting protrusion 4 is fixedly connected to the middle of the top front side of box 1. Cover plate 5 is rotatably connected to the upper surface of box 1, and connecting block 6 is rotatably connected to the middle rear side of cover plate 5. A through hole is opened at the front end of connecting protrusion 4, and connecting protrusion 4 and the hole opened at the upper end of connecting block 6 are connected through each other.

[0027] When the cover 5 is closed on top of the box 1, pass the through hole at the bottom of the connecting block 6 through the connecting protrusion 4, and then use the locking piece to pass through the through hole at the front of the connecting protrusion 4. Hold the handle 3 and lift the right side of the box 1 to move the microcrack detection device.

[0028] Example 2: Existing concrete microcrack detection equipment is inconvenient to adjust when detecting concrete at different heights. Therefore, this example uses the following technical solution: Figure 1 , Figure 2 Figures 4-6 As shown;

[0029] A storage box 7 is fixedly connected to the upper rear side of the interior of box 1. A lifting device 8 is rotatably connected to the upper left side and the lower right side of the front side of the interior of box 1. The lifting device 8 is composed of a support column 801, a storage slot 802, a lifting rod 803, a motor 804, a lead screw 805, and a first stabilizing bolt 806. The storage slot 802 is opened inside the support column 801, and the lifting rod 803 is slidably connected inside the storage slot 802. A groove is opened on the inner side of the top of the lifting rod 803. The inner side of the top of the lifting rod 803 is engaged with the T-shaped block 10. The motor 804 is fixedly connected to the bottom of the interior of the storage slot 802. The output shaft of the motor 804 is fixedly connected to the lead screw 805. The outer side of the lead screw 805 is threadedly connected to the inner side of the lifting rod 803. The first stabilizing bolt 806 is threadedly connected to the outer side of the top of the lifting rod 803.

[0030] When testing is required, lift both the left and right lifting devices 8 so that they are vertically positioned inside the box 1. The unused horizontal plate 9 is stored in the storage box 7. After the lifting devices 8 are raised, remove the horizontal plate 9. Engage the T-shaped blocks 10 at both ends of the horizontal plate 9 into the slots on the inner side of the top of the lifting rod 803. Then tighten the first stabilizing bolt 806 at the outer end of the lifting rod 803 to fix the horizontal plate 9 to the lifting rod 803. Testing can then commence. Because of the wheels 2, testing can be performed horizontally. When the position of the moving detection equipment needs to be adjusted and the height of the detection probe 11 needs to be adjusted, the motor 804 inside the support column 801 is started, so that the output shaft of the motor 804 drives the lead screw 805 to rotate. Since the lifting rod 803 is threadedly connected to the outer side of the lead screw 805, and since the inner side of the top of the lifting rod 803 is restricted by the horizontal plate 9, when the lead screw 805 rotates, the lifting rod 803 is carried by the lead screw 805 to move up and down in the storage slot 802. The above steps make the lifting rod 803 move up and down with the horizontal plate 9 to adjust the height of the detection equipment.

[0031] Example 3: In an existing concrete microcrack detection device, some internal structures are not easily supported stably. Therefore, this example uses the following technical solution, such as... Figure 1 , Figures 2-4 and Figure 6 As shown;

[0032] The top of the lifting device 8 is engaged with a horizontal plate 9, and T-shaped blocks 10 are fixedly connected to the middle of the bottom of both sides of the horizontal plate 9. A detection probe 11 is fixedly connected to the middle of the front side of the horizontal plate 9. Slide grooves 12 are opened on both the left and right sides of the front end of the box 1. A baffle 13 is slidably connected in the slide groove 12. A second stabilizing bolt 14 is threadedly connected to the rear end of the outer side of the baffle 13. The outer side of the second stabilizing bolt 14 is in contact with the inner outer side of the slide groove 12.

[0033] After lifting one end of the lifting device 8, the lifting device 8 is vertical on the box 1. Then, the baffle 13 is moved forward so that the outer side of the inner end of the baffle 13 is in contact with the inner side of the support column 801. When the front side of the rear end of the baffle 13 is in contact with the rear side of the support column 801, the second stabilizing bolt 14 is tightened to fix the baffle 13 in the slide groove 12, so that the lifting device 8 can be fixed inside the box 1 and the lifting device 8 can be stably fixed.
