Technical Field

[0001] The utility model relates to the field of crack detectors, in particular to a high-precision road surface crack detection device. Background Art

[0002] Pavement crack detection plays a crucial role in highway construction and maintenance. As crucial transportation infrastructure, the safe operation of highways is directly linked to public safety and the stable development of the economy. Accurately and promptly detecting pavement cracks provides crucial data for decision-making regarding highway maintenance and repairs, significantly impacting the safe operation and extended service life of highways. Crack detection devices act as diagnostic tools for highway health. By accurately monitoring pavement conditions, they can identify potential problems promptly and provide guidance for subsequent maintenance and repair work. With accurate data, maintenance personnel can develop more scientific and rational maintenance plans and address cracks in a targeted manner, effectively preventing further expansion and ensuring that highways remain in optimal operating condition.

[0003] Existing pavement crack detection systems use probes that come into direct contact with the ground. Because the road surface is often contaminated by debris such as small stones and gravel, the probes are easily impacted by these debris, causing physical damage to the probes. This in turn affects their detection accuracy and service life, making proper detection difficult, increasing maintenance costs, and impacting the continuity of detection work. To address these issues, a high-precision road pavement crack detection device has been proposed. Utility Model Content

[0026] 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.

[0027] Reference Figure 1 、 Figure 2 and Figure 3 , the utility model provides an embodiment: a high-precision highway pavement crack detection device, including a detection body 1. During the detection process, the operator can process the data transmitted by the probe 3 through the detection body 1. A plug 7 is fixedly connected to the top of the detection body 1, and the plug 7 is connected to the probe 3 through the data line 2. Through the connection between the plug 7 and the data line 2, the probe 3 can transmit the information of the pavement cracks to the detection body 1 in real time for processing. A protective component is provided on the outside of the probe 3 to protect the probe 3 during detection. A portable component is provided at the bottom of the detection body 1 to facilitate the detection body 1 to be firmly placed in the operator's hand;

[0028] The protective assembly includes a connecting tube 4, which is fixedly connected to the outside of the probe 3, effectively protecting the probe 3 from damage by debris such as road debris. A sleeve 403 is rotatably connected to the outside of the connecting tube 4, providing support for the slide 402 and ball bearing 404. Multiple slides 402 are fixedly connected to the inside of the sleeve 403. The outside of the connecting tube 4 is provided with multiple arcuate grooves 401. The slides 402 slide within the arcuate grooves 401, making the rotation and movement of the sleeve 403 more stable and providing a track for the slide 402. The combination of the slide 402 and the arcuate grooves 401 acts as a limiter, preventing the sleeve 403 from excessive rotation.

[0029] Reference Figure 4 and Figure 5 The portable component includes a fixed plate 5, which serves as a part of connecting the portable component to ensure a firm connection between the portable component and the detection body 1. The fixed plate 5 is fixedly connected to the bottom of the detection body 1, and the end of the fixed plate 5 is rotatably connected to a rotating rod 501, providing a rotating axis for the carrying rod 502. The outside of the rotating rod 501 is fixedly connected to the carrying rod 502, which can be more stably fixed on the operator's hand during use. A slide groove 503 is provided on the inner side of the carrying rod 502 to provide space for the sliding of the slide rod 504. The inside of the slide groove 503 is slidably connected to the slide rod 504, and through the rotation of the carrying rod 502, the slide rod 504 slides in the slide groove 503 under the tension contraction of the spring 507.

[0030] A baffle 505 is fixedly connected to the outside of the slide bar 504, providing a connection point between the slide bar 504 and the spring 507. The bottom of the baffle 505 is fixedly connected to the spring 507. A placement slot 506 is defined at the bottom of the detection body 1. One end of the spring 507 is fixedly connected to the inner wall of the placement slot 506. The handle 502 is disposed within the placement slot 506 via the rotating rod 501. The tension of the spring 507 allows the handle 502 to be retracted into the placement slot 506 when not in use, making it easier to carry and store the detection body 1.

[0031] Reference Figure 5 and Figure 6 The end of the arc-shaped groove 401 is provided with a limiting groove 405, and the slide post 402 is engaged with the inside of the limiting groove 405. The limiting groove can be engaged with the slide post 402, further fixing the position of the sleeve 403 and ensuring the stability of the contact between the ball 404 and the ground. The outer part of the sleeve 403 is rotatably connected to multiple balls 404, which are used to contact the road surface during detection, allowing the probe 3 to move more smoothly on the road surface during the detection process, reducing friction with the ground, thereby protecting the probe 3 from wear. A display screen 6 is fixedly connected to the surface of the detection body 1, allowing the operator to easily operate and set it, thereby improving the efficiency and convenience of detection.

[0032] Working principle: First, remove the detection body 1 from the box, and then connect the probe 3 to the plug 7 via the data cable 2. When the probe 3 is placed on a road crack, first rotate the sleeve 403 to the left, so that the slide 402 slides along the arc groove 401, and then the sleeve 403 drives the ball 404 to move. Then, the slide 402 slides into the limit groove 405 at the end of the arc groove 401, so that the ball 404 contacts the ground. This prevents the probe 3 from being affected by debris on the ground when detecting road cracks, and thus protects the detection head from wear.

[0033] Secondly, when the operator is inspecting the ground and needs to operate data on the upper display screen 6, the operator rotates the handle 502 out of the placement slot 506. At this time, the tension of the spring 507 pulls the slide bar 504 through the baffle 505 to slide in the slide slot 503, thereby pulling the handle 502 close to the operator's hand, so that the detection body 1 can be fixed on the operator's hand, making it convenient for the operator to operate the data.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
