Description

Technical Field

[0001] This utility model mainly relates to the technical field of crack detection, specifically a road crack detection device. Background Technology

[0002] Cracks are one of the most common, easily occurring, and earliest-developing road surface defects. They accompany roads throughout their entire service life and worsen with age. Cracks not only affect the aesthetics and driving comfort of the road surface but also easily propagate, causing structural damage and shortening its lifespan. Therefore, cracks should be sealed and repaired promptly. Otherwise, rainwater and other debris will seep into the surface structure and subgrade along the cracks, reducing the road's load-bearing capacity and accelerating localized or widespread damage. When cracks appear on roads and bridges, construction workers typically use crack detection devices to measure their depth to assess the extent of damage.

[0003] Existing technology discloses a municipal road crack detection device, including a mobile trolley and two long rods fixedly mounted on one side of the mobile trolley. Connecting plates are movably fitted onto the outer surfaces of both long rods. In this application, when detecting road cracks, a pushing device moves the device to the detection location. During crack detection, a limiting rod is pulled out, and the elastic force generated by two compression springs pushes a support plate towards the ground, causing one side of the bristles of the two cleaning brushes to press firmly against the ground. The external power supply to the drive motor is turned on, causing two second rotating rods to drive the two cleaning brushes to rotate. This propels the entire detection device. The rotating cleaning brushes first clean the road cracks, and then a laser scanner detects the road, making the road cracks clearly visible, improving detection accuracy and reducing the possibility of misjudgment and missed detection.

[0004] However, the cleaning brushes in the aforementioned devices can only clean general impurities on the road surface. They are ineffective at cleaning stubborn impurities on the road surface, such as sticky mud, oil-stained gravel, and impurities in deeper parts of cracks or narrow gaps, which reduces the accuracy of subsequent crack detection results.

[0025] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0026] Example

[0027] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 3 and 4, a road crack detection device includes a detection vehicle 1. A detection component 2 is provided at the front end of the bottom of the detection vehicle 1, and a cleaning component 3 is provided at the rear end of the bottom of the detection vehicle 1. The cleaning component 3 includes a flushing system 4 and a cleaning system 5. The flushing system 4 is provided with a high-pressure flushing pipe 401, which is connected to a high-pressure water tank 403. The high-pressure water tank 403 is located inside the detection vehicle 1, and the high-pressure flushing pipe 401 is provided with a flushing port 402. The flushing port 402 sprays high-pressure water to flush away impurities on the road surface. The cleaning system 5 is provided with a cleaning disc 501, which is symmetrically distributed at the bottom of the detection vehicle 1. The cleaning disc 501 cleans the impurities on the road surface by rotating on its own.

[0028] It should be noted that when road cracks need to be inspected, the staff pulls the inspection vehicle 1 to work in the crack area. The flushing system 4 and the cleaning system 5 work together to clean the impurities on the road surface. The flushing system 4 is equipped with flushing nozzles 402 that can spray high-pressure water in a specific manner to flush away stubborn impurities on the road surface. With the impact force of the high-pressure water, the stubborn impurities are separated from the road surface. At the same time, the cleaning disc 501 of the cleaning system 5 cleans general impurities and separated stubborn impurities by its own rotation, providing a good working environment for subsequent crack inspection.

[0029] It should be noted that the high-pressure water tank 403 inside the inspection vehicle 1 provides a continuous and stable high-pressure water flow to the high-pressure flushing pipe 401, while several flushing ports 402 are equidistantly arranged on the high-pressure flushing pipe 401. The equidistant arrangement design allows the high-pressure water flow to evenly cover the road surface, and the flushing port 402 is inclined at an angle of 10°-30° to the bottom surface of the road. This inclined angle setting allows the high-pressure water flow to impact the impurities on the road surface at the optimal angle, improving the flushing effect.

[0030] It should be noted that the bottom surface of the cleaning disc 501 is covered with cleaning brushes 5011 arranged in a circular array. The circular array of cleaning brushes 5011 can fully cover the area traversed by the cleaning disc 501 when it rotates. The bristles of the cleaning brushes 5011 are made of a mixture of nylon and steel wire. The nylon material has good flexibility and wear resistance, while the steel wire material increases the hardness of the bristles and cleaning ability. This mixture of materials can adapt to different types of impurities and perform cleaning work more effectively.

[0031] Please refer to the attached document carefully. Figure 2 , 3 As shown in Figures 4 and 5, the cleaning system 5 includes two symmetrically arranged rotating shafts 502. One end of the rotating shaft 502 near the road surface is connected to a cleaning disc 501, and the other end is connected to a lifting plate 503. A driven gear 504 is provided on the rotating shaft 502. The driven gear 504 is connected to a driving gear 506 through a chain 505. The driving gear 506 is connected to the output end of a drive motor 507. The drive motor 507 is mounted on the lifting plate 503. The top of the lifting plate 503 is connected to the lifting end of two symmetrically arranged electric lifting rods 508. The end of the electric lifting rod 508 away from the lifting plate 503 is connected to a fixing plate 509. The fixing plate 509 is detachably connected to the inner wall of the inspection vehicle 1.

[0032] It should be noted that when performing road crack detection, the drive motor 507 operates, and its output shaft drives the drive gear 506 to rotate at high speed. The drive gear 506 drives the driven gear 504 through the chain 505, thereby causing the rotating shaft 502 and the cleaning disc 501 to rotate together, realizing the cleaning operation on the road surface. Moreover, the speed of the drive motor 507 can be flexibly adjusted according to actual cleaning needs through the intelligent control system 6 to meet the requirements of different road conditions and cleaning levels. In addition, through the lifting adjustment of the electric lifting rod 508, the height of the lifting plate 503 can be flexibly adjusted according to the actual road conditions, such as the flatness and slope of the road surface, as well as different cleaning task requirements, thereby precisely controlling the distance and contact pressure between the cleaning disc 501 and the road surface to achieve the best cleaning effect.

[0033] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 3 and 4, the detection component 2 includes a laser scanner 201, which measures parameters such as the depth, width, and length of cracks by emitting a laser beam and receiving reflected light.

[0034] It should be noted that the laser scanner 201 employs advanced optical measurement technology. During operation, it emits high-energy-density laser beams at extremely high speeds. These laser beams are projected vertically and uniformly onto the road surface. When the laser beams come into contact with cracks, reflection occurs. The high-sensitivity receiver inside the laser scanner 201 can quickly capture the reflected light and, through precise time measurement technology, calculate the time difference between the laser beam's emission and reception. Based on the constant speed of light in air, combined with trigonometric function principles, key parameters such as the depth, width, and length of the crack can be accurately calculated.

[0035] Please refer to the attached document carefully. Figure 1 , 4 As shown, the inspection vehicle 1 is also equipped with an intelligent control system 6, which is electrically connected to the inspection component 2, the flushing system 4 and the cleaning system 5 respectively. The intelligent control system 6 is equipped with a control panel 601, which is located on the outer side of the inspection vehicle 1.

[0036] It should be noted that when the detection component 2 detects crack information, the intelligent control system 6 will quickly analyze the severity of the crack according to a preset algorithm and promptly feed this information back to the operator. Simultaneously, it can automatically adjust the water pressure, water flow, and flushing time of the washing system 4 based on the detection results and road conditions, and optimize the rotation speed and cleaning intensity of the cleaning disc 501 in the cleaning system 5, achieving intelligent and automated operation of the entire detection and cleaning process. Furthermore, the control panel 601 of the intelligent control system 6 allows for quick start, stop, and parameter adjustment of the system, enabling operators to intuitively view the system's operating status, detection data, and various parameter settings, greatly improving work efficiency and operational convenience.

[0037] The specific operation method of this utility model is as follows:

[0038] Before conducting road crack detection, set the parameters in Cleaning Component 3 through Control Panel 601, and then start Cleaning Component 3.

[0039] The high-pressure water tank 403 of the flushing system 4 injects high-pressure water into the high-pressure flushing pipe 401. Then, the flushing port 402 sprays high-pressure water at a specific angle to flush away stubborn impurities on the road surface, causing the stubborn impurities to separate from the road surface. The electric lifting rod 508 in the cleaning system 5 extends, causing the cleaning brush 5011 at the bottom of the cleaning disc 501 to contact the ground, driving the motor 507 to run. Its output shaft drives the drive gear 506 to rotate at high speed. The drive gear 506 drives the driven gear 504 through the chain 505, thereby causing the rotating shaft 502 and the cleaning disc 501 to rotate together. The cleaning brush 5011 rotates accordingly, cleaning the stubborn impurities that have been dispersed by the flushing system 4.

[0040] Then, the detection component 2 uses the laser scanner 201 to detect the cleaned cracks, calculates key parameters such as the depth, width and length of the cracks, and transmits the data to the intelligent control system 6. The intelligent control system 6 will quickly analyze the severity of the cracks according to the preset algorithm and promptly feed this information back to the operator through the control panel 601.

[0041] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
