Description

Technical Field

[0001] The present invention belongs to the technical field of crack identification, and in particular relates to a building structure crack identification device. Background Art

[0002] A building structure crack identification device is a device or system that uses technical means (such as optics, image processing, sensors, etc.) to automatically or semi-automatically detect, identify and analyze cracks on the surface of buildings or structures. Its core purpose is to quickly and accurately detect structural cracks and assess their severity, providing a scientific basis for building safety assessment, repair and reinforcement. Laser scanners measure surface morphology and identify cracks through reflected light, and ultrasonic equipment detects internal cracks or damage through changes in the propagation speed of sound waves.

[0003] Traditional equipment mostly uses fixed or single-angle detection methods, which makes it difficult to achieve multi-directional and comprehensive crack identification of ground structures (such as bridge piers, tunnel sidewalls, building foundations, etc.). For example, for scenarios where horizontal, vertical and inclined surface cracks need to be detected simultaneously, existing equipment needs to frequently adjust its position or rely on the collaboration of multiple devices, resulting in low detection efficiency and easy omission of hidden cracks. On the other hand, most device designs do not fully consider the portability requirements of on-site use. The equipment is large and heavy, and needs to be carried by vehicles or multiple people, making it difficult to adapt to narrow spaces or field working environments. This dual defect of "many blind spots in detection" and "difficult mobile deployment" not only increases detection costs and time, but is also likely to lead to missed detection of key cracks, thereby threatening the safety of building structures.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0032] Example 1:

[0033] See also Figures 1-6 As shown, a building structure crack identification device includes:

[0034] Mobile seat 1;

[0035] The mounting column 2 is fixedly connected to the top of the mobile base 1;

[0036] A gripping handle 3 is fixedly mounted on the outer side wall of the mounting column 2;

[0037] The adjusting mechanism 4 is arranged at the top of the mounting column 2;

[0038] A mounting mechanism 5, the mounting mechanism 5 being fixedly connected to the outside of one side of the adjustment mechanism 4;

[0039] The folding mechanism 6 is installed on the outer side wall of the mounting mechanism 5. The folding mechanism 6 includes a first motor 601, a first articulated arm 602 and a second motor 603. The output end of the first motor 601 is fixedly connected to the first articulated arm 602. The second motor 603 is installed on the outside of one side of the first articulated arm 602. The output end of the second motor 603 is fixedly connected to the second articulated arm 604. The third motor 605 is installed on the outside of the second articulated arm 604. The output end of the third motor 605 is fixedly connected to the connecting seat 606. The first articulated arm 602 and the second articulated arm 604 are rotatably connected. The connecting seat 606 and the second articulated arm 604 are rotatably connected. The first motor 601, the second motor 603 and the third motor 605 are all electrically connected to the controller through wires. The bottom end of the folding mechanism 6 is fixedly connected to the identification detector 7. The outside of one side of the folding mechanism 6 is fixedly connected to the rotating mechanism 8. The outside of the adjustment mechanism 4 is provided with a lifting mechanism 9.

[0040] Specifically, through the operation of the first motor 601, the second motor 603 and the third motor 605, the first articulated arm 602 and the second articulated arm 604 can be adjusted to different positions, thereby adjusting the identification detector 7 installed at the bottom of the connecting seat 606, and in conjunction with the operation of the third motor 605, the angle of the identification detector 7 can be adjusted.

[0041] As can be seen from the above, when the identification detector 7 is used to detect cracks in structures at different positions, the threaded rod 901 can be rotated first by rotating the handle 402. At this time, the height of the folding mechanism 6 can be adjusted and controlled through the threaded connection between the threaded sleeve 902 and the threaded rod 901 and the sliding limit of the sliding limit column 403 on the sleeve seat 404. Subsequently, through the operation of the first motor 601, the second motor 603 and the third motor 605, the angle of the first articulated arm 602 and the second articulated arm 604 can be adjusted, so that the identification detector 7 can be adjusted at multiple angles and the height can be raised and lowered, so as to realize the scenario where the identification detector 7 needs to detect horizontal, vertical and inclined surface cracks at the same time.

[0042] refer to Figure 2 and Figure 6As shown, the adjustment mechanism 4 includes a first mounting seat 401, a rotating handle 402 and a sliding limit column 403. The first mounting seat 401 is fixedly connected to the top of the mounting column 2. A rotating handle 402 is provided above the first mounting seat 401. A sliding limit column 403 is fixedly connected to one side of the first mounting seat 401. A sleeve seat 404 is provided on the outside of the sliding limit column 403. A mounting groove 405 is provided inside the sleeve seat 404. The sleeve seat 404 is slidably connected to the outside of the sliding limit column 403. The rotating handle 402 is fixedly connected to the top of the lifting mechanism 9, and the lifting mechanism 9 is inserted into the inside of the mounting groove 405.

[0043] Specifically, when the handle 402 is rotated, through the threaded connection between the threaded rod 901 and the threaded sleeve 902, and the sliding operation of the sleeve 404 on the sliding limit column 403, the height of the sleeve 404 on the sliding limit column 403 can be adjusted and controlled, thereby realizing the height lifting and lowering adjustment of the identification detector 7, and improving the convenience during detection.

[0044] Example 2:

[0045] refer to Figures 1-6 As shown, the mounting mechanism 5 includes a clamping seat 501, an adjusting screw 502 and a clamping plate 503. The clamping seat 501 is fixedly connected to the outside of one side of the rotating mechanism 8. The adjusting screw 502 is inserted into the interior of the clamping seat 501. The top of the adjusting screw 502 is fixedly connected to the clamping plate 503. A fixing piece 504 is inserted into the interior of the clamping seat 501. The adjusting screw 502 is threadedly connected to the clamping seat 501. The fixing piece 504 is fixedly connected to the outside of the sleeve seat 404. The fixing piece 504 is fixed to the inside of the clamping seat 501 through the clamping plate 503. The rotating mechanism 8 includes a mounting cover 801, a fourth motor 802 and a first Second mounting seat 803, a fourth motor 802 is arranged inside the mounting cover 801, the output end of the fourth motor 802 is fixedly connected to the second mounting seat 803, the fourth motor 802 is electrically connected to the controller through a wire, the first motor 601 is installed outside the second mounting seat 803, the lifting mechanism 9 includes a threaded rod 901, a threaded sleeve 902 and a fixed seat 903, the threaded rod 901 is externally sleeved with a threaded sleeve 902, one side of the threaded sleeve 902 is fixedly connected to the fixed seat 903, the threaded sleeve 902 is threadedly connected to the threaded rod 901, and the fixed seat 903 is fixedly connected to the inner wall of the mounting groove 405.

[0046] Specifically, after the fixing seat 903 is fixed inside the mounting groove 405, the threaded rod 901 is rotated, so that the threaded sleeve 902 can be raised and lowered and adjusted outside the threaded rod 901, thereby driving the mounting groove 405 to be raised and lowered. After the fourth motor 802 is powered on, the second mounting seat 803 is rotated, which can rotate the angle of the identification detector 7, so that the identification detector 7 can detect the side cracks of the structure.

[0047] From the above, it can be seen that when the adjusting screw 502 is rotated, the clamping plate 503 can be telescopically adjusted inside the clamping seat 501, so that the clamping plate 503 clamps and fixes the fixing part 504 inside the clamping seat 501, which is convenient for quickly clamping, installing and disassembling the fixing part 504 in the clamping seat 501, and thus the detection and identification device can be quickly disassembled and assembled in narrow spaces or field working environments.
