Description

Technical Field

[0001] This utility model relates to the field of tunnel defect detection equipment design technology, specifically to a vehicle-mounted three-dimensional tunnel defect detector. Background Technology

[0002] With the continuous development of transportation infrastructure, tunnels are becoming increasingly prevalent in highway construction. The quality and safety of tunnels directly affect the normal operation of traffic and the safety of people's lives and property. Therefore, regular inspection and evaluation of tunnels are crucial. Traditional tunnel inspection methods mainly rely on manual inspection, which is not only inefficient and labor-intensive, but also highly susceptible to human factors, making it difficult to comprehensively and accurately reflect the actual condition of the tunnel. To overcome the aforementioned shortcomings of manual inspection, related technologies have proposed mounting a three-dimensional tunnel defect detector on a vehicle. This can greatly improve the efficiency of tunnel inspection. However, existing three-dimensional defect detectors are mostly fixed to the roof of the vehicle's cab. To ensure that the radar can comprehensively inspect the entire cross-section of the tunnel, a cantilever extending towards the rear of the vehicle is required, with the detection radar installed at the end of the cantilever. Due to the large length of the cantilever and the large mass of the radar, the cantilever deforms significantly under stress during long-term operation on bumpy roads, leading to inaccurate inspection results or even damage to the cantilever structure, affecting normal inspection operations. Utility Model Content

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. In the drawings, for clarity, the thickness of regions and layers is exaggerated. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0028] The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention. However, those skilled in the art will recognize that the technical solutions of the present invention can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0029] The following example describes a vehicle-mounted three-dimensional tunnel defect detector of this utility model. This example is only a part of the embodiments of this utility model, but the protection scope of this utility model is not limited thereto. All other embodiments obtained by those skilled in the art without creative effort should be covered within the protection scope of this utility model.

[0030] Please refer to the reference. Figures 1 to 9According to an embodiment of the present invention, a vehicle-mounted tunnel three-dimensional defect detector is provided, including a detector body 1 and an assembly bracket 2. The assembly bracket 2 has a first region (not indicated in the figure, corresponding to the middle region of the vehicle) that is detachably connected to the passenger compartment roof of a vehicle 100 (e.g., detachably connected by bolts) and a second region (not indicated in the figure, corresponding to the rear region of the vehicle) that is supported on the rear roof of the vehicle 100. The bottom surface of the second region of the assembly bracket 2 is provided with a support rod 21, the bottom end of which can be supported on the rear roof. The detector body 1 is assembled on the top surface of the second region. The second region has a rear side beam 22 that is flush with the rear end face of the vehicle 100. The radar 11 of the detector body 1 protrudes along the length direction of the vehicle 100 to the side of the rear side beam 22 away from the first region, that is, the radar 11 in the present invention protrudes from the rear end of the vehicle 100.

[0031] In this technical solution, the assembly bracket 2 has a second area corresponding to the rear roof position of the vehicle 100, and the detector body 1 is assembled to the second area so that the radar 11 on it protrudes from the rear side beam 22. In this way, the assembly bracket 2 and its bottom support rod 21 can reliably support the detector body 1. The protruding length of the radar 11 does not need to be too large or can even be zero. This ensures that the position of the radar 11 is reliable and stable during tunnel detection, effectively preventing the deformation or even damage of the long cantilever set in the prior art to ensure the scanning detection range of the radar 11.

[0032] In some embodiments, the support rod 21 is a threaded rod, and the bottom end of the threaded rod is threadedly connected to a support seat 211. The support seat 211 has a threaded sleeve 212 that is threadedly connected to the threaded rod. In this way, different lengths of threaded sleeves 212 can be selected according to the actual height difference requirements. Then, the support length of the support rod 21 can be adjusted by adjusting the mating length between the threaded sleeve 212 and the threaded rod. This makes the assembly bracket 2 of this utility model applicable to different types of vehicles 100, improving its versatility. In another preferred embodiment, the top end of the support rod 21 is threadedly connected to the assembly bracket 2. The support height of the support rod 21 can also be adjusted by adjusting the length of the threaded connection between the two. In a specific embodiment, corresponding connecting seats (not shown in the figure) are respectively provided on the left and right sides of the assembly bracket 2. These connecting seats are welded integrally with the assembly bracket 2, and the support rod 21 is threadedly connected to the connecting seats. This allows the assembly bracket 2 to be assembled using commonly used aluminum alloy profiles. The use of aluminum alloy profiles to assemble the assembly bracket 2 reduces vehicle weight, thereby reducing driving energy consumption. See details... Figure 2As shown, aluminum alloy profiles are assembled into a rectangular frame. The width of the rectangular frame should not be greater than the width of the vehicle 100, and should be matched as closely as possible to the width of the roof rack of the vehicle 100 so that it can be directly and detachably connected to the aforementioned roof rack.

[0033] In some embodiments, a suction cup pad 213 is fixedly connected to the bottom surface of the support base 211. Specifically, the suction cup pad 213 is made of rubber and can be pasted onto the bottom surface of the support base 211. This enables flexible support to the surface of the vehicle 100 while further ensuring the reliable support function of the support rod 21 through adsorption.

[0034] In some embodiments, a first assembly plate 23 is connected to the top side of the second region of the assembly bracket 2, and the detector body 1 includes a base 12, which is detachably mounted on the first assembly plate 23 via the base 12. See details below. Figure 4 As shown, a quick-locking screw 17 (commercially available) is provided at each of the four corners of the base 12. This quick-locking screw 17 enables quick and convenient connection with the corresponding holes and slots on the first mounting plate 23. In this technical solution, the first mounting plate 23 enables a detachable connection between the assembly bracket 2 and the main body of the detector 1. The supporting area is sufficient to ensure reliable support and positioning of the main body of the detector 1. Specifically, the first mounting plate 23 and the assembly bracket 2 can be welded together. In another embodiment, a second mounting plate 24 is welded to the bottom surface corresponding to the first area of ​​the assembly bracket 2, enabling a detachable connection between the assembly bracket 2 and the luggage rack of the vehicle 100.

[0035] The addition of a handle 16 on the top surface of the base 12 further facilitates the disassembly, assembly, and transfer of the main body 1 of the detector.

[0036] In some embodiments, the detector body 1 further includes a camera array assembly 13 and illumination array assemblies 14 located on both sides of the camera array assembly 13, with the two illumination array assemblies 14 respectively located on the two end faces of the camera array assembly 13 in the length direction of the vehicle 100. In this technical solution, by setting a set of illumination array assemblies 14 on the front and rear sides of the camera array assembly 13, a uniform distribution of illumination light can be achieved, thereby improving the image quality and effect of the camera array assembly.

[0037] In some embodiments, the camera array assembly 13 includes a first housing 131, with cameras 132 arranged in a circumferential array on the outer circular wall of the first housing 131 (forming a ring camera array). The lighting array assembly 14 includes a second housing 141, with multiple lighting lamps 142 arranged in a circumferential array on the outer circular wall of the second housing 141 (forming a ring lighting array). The second housing 141 is detachably assembled to the first housing 131, and the first housing 131 is fixed to the base 12. An electrical connection connector 143 (including male and female terminals) is provided between the second housing 141 and the first housing 131 to supply power to each of the lighting lamps 142 via the camera array assembly 13. In one specific embodiment, the aforementioned lighting lamp 142 is an LED light panel.

[0038] In this technical solution, by setting male and female terminals that are mutually matched on the first housing 131 and the second housing 141 respectively, the power cord can be connected after the two are assembled. The structure is simple and compact.

[0039] In some embodiments, in the length direction of the vehicle 100, the cameras 132 in the two camera array assemblies 13 are arranged alternately along the circumferential direction, so that the lighting lamps 142 on the front and rear sides are arranged alternately in the circumferential direction of the second housing 141, which can further improve the uniformity of the lighting.

[0040] In some embodiments, a support plate 15 is provided between the top surface of the base 12 and the second housing 141, which can provide support for the cantilever portion of the second housing 141 and improve the reliability of the second housing 141.

[0041] In some embodiments, the second housing 141 has an air inlet 1411 and an air outlet 1412. A fan 144 is provided in the air inlet 1411 and / or the air outlet 1412. The fan 144 is used to drive airflow from the air inlet 1411 into the second housing 141 and out of the air outlet 1412. This can achieve heat dissipation for the components (mainly the lighting lamp 142) inside the second housing 141 and prevent damage to the components due to excessive temperature.

[0042] In some embodiments, the second housing 141 contains a circuit board assembly 145. The circuit board assembly 145 includes a mounting plate 1451 fixedly connected to the second housing 141 and a plurality of power drive boards 1452 detachably connected to the mounting plate 1451. The number of power drive boards 1452 is equal to the number of lighting lamps 142 and they are arranged in a one-to-one correspondence. The power drive boards 1452 are symmetrically arranged on opposite sides of the mounting plate 1451. In this technical solution, each power drive board 1452 is symmetrically located on both sides of the mounting plate 1451, which can improve the compactness of the structure. It is understood that each of the aforementioned lighting lamps 142 specifically includes a reflector and a lens 146 located at the opening of the reflector. A lens pressing plate 147 can press the lens 146 into the opening of the reflector, while the aforementioned lighting lamp 142 is located at the bottom of the reflector.

[0043] In some embodiments, the first housing 131 is provided with an aviation power connector 1311 and an optical fiber connector 1312 to realize the electrical connection of power and signal with the control host of the detector. The first housing 131 is also provided with a pin terminal block 133 (six pins) and a switch 134; and / or, each of the cameras 132 is equipped with a low distortion lens 1321, and each camera 132 is preferably a high resolution industrial camera.

[0044] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
