Description

Technical Field

[0001] This utility model is specifically a high-efficiency tunnel defect inspection vehicle, which relates to the field of tunnel defect detection technology. Background Technology

[0002] After a tunnel is put into operation, it is inevitable that defects such as leakage and lining deformation and cracking will occur. Regular inspections of the tunnel are necessary to detect and treat defects early and eliminate them in the early stages.

[0003] Currently, tunnel defects are inspected manually. Because tunnels are very high, it's difficult to identify defects visually alone. Therefore, inspectors often need to use aerial work platforms used for street light maintenance to get close to the tunnel walls and identify defects. This method requires inspectors to stand inside a suspended platform and inspect by moving the platform. The problems with this method are high workload, low efficiency, and the risk of falls from heights for the inspectors. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model discloses a high-efficiency tunnel defect inspection vehicle, which adopts the following technical solution:

[0005] A high-efficiency tunnel defect inspection vehicle includes:

[0006] The vehicle body has a platform;

[0007] Lateral and longitudinal telescopic rods are installed on the platform;

[0008] The diagonal brace connects the horizontal telescopic bar and the vertical telescopic bar, and multiple cameras facing the tunnel wall are installed on the diagonal brace.

[0009] The elastic wall-contacting positive electrode is set at the telescopic end of the longitudinal telescopic rod and is used to apply a positive voltage to the tunnel wall.

[0011] The detection system includes a leakage detection device and a display. The display is connected to a camera, and the leakage detection device is connected to a positive electrode and a negative electrode of the elastic contact wall.

[0012] Further improvements to the technical solution: Both the elastic wall-contact positive electrode and the elastic wall-contact negative electrode are composed of an insulating hinge base, a conductive hinge arm, a conductive roller, and a tension spring. The conductive roller is set on the conductive hinge arm and is used to contact the tunnel wall surface; the tension spring is set between the insulating hinge base and the conductive hinge arm and is used to press the conductive roller onto the tunnel wall surface.

[0013] Further improvement to the technical solution: The diagonal brace is an arc-shaped rod, and multiple lighting lamps are also installed on the diagonal brace.

[0015] Further improve the technical solution: both the lateral telescopic rod and the longitudinal telescopic rod are three-section hydraulic telescopic rods.

[0016] After implementing the above technical solution, the beneficial effects of this utility model compared to the prior art are:

[0027] A high-efficiency tunnel defect inspection vehicle, relating to the field of tunnel defect detection technology, is mainly used to solve the problems of high work intensity, low efficiency, and safety in existing technologies. The composition and working principle of this tunnel defect inspection vehicle are described in detail below.

[0028] See attached document Figure 1 and attached Figure 2 This tunnel defect inspection vehicle mainly consists of a vehicle body (1), a transverse telescopic rod (2), a longitudinal telescopic rod (3), a diagonal brace (4), a positive electrode for elastic wall contact (5), a negative electrode for elastic wall contact (6), and a detection system.

[0029] Vehicle body 1 is a mobile inspection platform. In this embodiment, vehicle body 1 is based on a truck, and after removing the side panels, the cargo bed serves as the platform.

[0030] The lateral telescopic rod 2 and the longitudinal telescopic rod 3 are installed on the platform. In this embodiment, both the lateral telescopic rod 2 and the longitudinal telescopic rod 3 are three-section hydraulic telescopic rods, with a minimum telescopic length of 2.4 meters and a maximum telescopic length of 6.3 meters.

[0031] The diagonal brace 4 connects the transverse telescopic rod 2 and the longitudinal telescopic rod 3. Three cameras 7 facing the tunnel wall are mounted on the diagonal brace 4 to replace visual inspection and check for tunnel defects. In this embodiment, the diagonal brace 4 is an arc-shaped rod, the shape of which closely resembles the shape of an arch. Multiple lighting lamps 8 are also installed on the diagonal brace 4 to provide illumination for the cameras 7. The diagonal brace 4 serves two purposes: first, to provide support for the transverse telescopic rod 2 and the longitudinal telescopic rod 3; and second, to act as a carrier for the installation of the cameras 7 and the lighting lamps 8.

[0032] See attached document Figure 3 The elastic wall-contacting positive electrode 5 is located at the telescopic end of the longitudinal telescopic rod 3 and is used to apply a positive voltage to the tunnel wall.

[0033] See attached document Figure 4 The elastic contact negative electrode 6 is located at the telescopic end of the longitudinal telescopic rod 3 and is used to apply a negative voltage to the tunnel wall.

[0034] Both the elastic contact positive electrode 5 and the elastic contact negative electrode 6 are composed of an insulating hinge base 51, a conductive hinge arm 52, a conductive roller 53, and a tension spring 54. The conductive roller 53 is mounted on the conductive hinge arm 52 for contacting the tunnel wall; the tension spring 54 is positioned between the insulating hinge base 51 and the conductive hinge arm 52 to press the conductive roller 53 against the tunnel wall. Clearly, this elastic design ensures that the conductive roller 53 remains in contact with the tunnel wall while the vehicle 1 is in motion.

[0035] The detection system includes a leakage detection device and a display. The display is connected to multiple cameras 7, and the leakage detection device is connected to the elastic wall contact positive electrode 5 and the elastic wall contact negative electrode 6. Inspection personnel, seated in the driver's cab, can observe the tunnel lining for deformation, cracks, or other defects through the display. The leakage detection device works by applying a detection voltage to the tunnel wall through the elastic wall contact positive electrode 5 and the elastic wall contact negative electrode 6. If there is no leakage on the tunnel lining wall, the leakage detection device will show high resistance on the tunnel lining wall. Water has a certain degree of conductivity; if the leakage detection device shows low resistance on the tunnel lining wall, it indicates leakage, causing a decrease in resistance.

[0036] The detection range of the elastic contact wall positive electrode 5 and the elastic contact wall negative electrode 6 is between the arch apex and the arch waist, almost covering half of the arch surface. When the vehicle body 1 travels in the opposite direction, the other half of the arch surface can be inspected. In addition, the reason why the elastic contact wall positive electrode 5 is set at the extension end of the longitudinal telescopic rod 3 and the elastic contact wall negative electrode 6 is set at the extension end of the longitudinal telescopic rod 3 is that the positive electrode located at the arch apex has a high voltage, and the negative electrode located at the arch waist is equivalent to a grounding wire, which can prevent pedestrians from being electrocuted.

[0037] See attached document Figure 4 and attached Figure 5 Even after retracting, the longitudinal telescopic rod 3 still has a considerable height. To avoid affecting the inspection vehicle's passability, the longitudinal telescopic rod 3 is hinged to the platform, and a hydraulic rod 9 is hinged between the vehicle body 1 and the longitudinal telescopic rod 3. When inspection is not required, the hydraulic rod 9 rotates the longitudinal telescopic rod 3 backward, lowering its height and improving the inspection vehicle's passability.

[0038] In summary, this tunnel defect inspection vehicle is equipped with cameras, allowing inspectors to observe whether the tunnel lining exhibits deformation, cracks, or other defects via a monitor while seated in the driver's cab. The vehicle also features a leakage detection system, enabling large-scale and efficient detection of tunnel leaks.

[0039] It is worth noting that the content not described in detail in the above embodiments is prior art. It is also worth noting that any additions, subtractions, substitutions, and improvements made by those skilled in the art based on the structure and principles of this utility model should be included within the protection scope of this utility model.
