DETAILED DESCRIPTION

[0031] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0032] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0033] like Figures 1 to 10 As shown, a tunnel inspection vehicle comprises an inspection vehicle body 1, a rotating support ring 2 is rotatably installed on the inner side of the inspection vehicle body 1, a seat body 3 is welded on the surface of the rotating support ring 2, and a placement box 4 is rotatably installed on the surface of the inspection vehicle body 1. The seat body 3 is installed on the surface of the inspection vehicle body 1 through a rotating rotating support ring 2. Therefore, when the inspection vehicle body 1 is driven and inspected inside the tunnel, an inspector can sit on the seat body 3 on the inspection vehicle body 1 for inspection. The seat body 3 can rotate with the rotating support ring 2, so that the inspector can perform a 360-degree rotation observation in the tunnel. The rotating placement box 4 on the inspection vehicle body 1 is used to place relevant tools, and the inspector can take relevant tools by rotating the placement box 4.

[0034] In this embodiment, a positioning support 9 is fixedly installed on the surface of the detection vehicle body 1, a positioning support groove 10 is opened on the surface of the positioning support 9, a detection support 5 is slidably installed on the inner wall of the positioning support groove 10, a first hydraulic telescopic rod 42 is slidably installed on the surface of the detection support 5, an auxiliary guide plate 43 is fixedly installed on the end of the first hydraulic telescopic rod 42 away from the detection support 5, and an annular light source plate 8 is fixedly installed on the side of the auxiliary guide plate 43 away from the first hydraulic telescopic rod 42. The annular light source plate 8 can be adjusted by the first hydraulic telescopic rod 42 to achieve the effect of flexible adjustment for tunnels of different sizes.

[0035] Among them, an annular uniform light source is installed on the side of the annular light source plate 8, and a heat dissipation groove 44 is provided on the surface of the annular light source plate 8. The heat dissipation groove 44 on the surface of the annular light source plate 8 can dissipate the heat generated by the annular light source plate 8 when it is in use, and a refrigeration system is arranged on the inner side of the annular light source plate 8 to effectively cool down the heat generated by the annular light source plate 8 when it emits annular light, thereby ensuring the service life of the annular light source plate 8. A second motor 45 is fixedly installed on the inner side of the annular light source plate 8, and an assembly plate 46 is fixedly installed on the output end of the second motor 45. A second hydraulic telescopic rod 47 is fixedly installed on the surface of the assembly plate 46, and a positioning box 48 is fixedly installed on the end of the second hydraulic telescopic rod 47 away from the assembly plate 46. A groove 49 is provided on the inner side of the positioning box 48, and a linear array camera 6 is arranged on the inner wall of the groove 49. A fixing clamp 50 is slidably installed on the inner wall of the positioning box 48. The fixing clamp 50 is in the shape of an L, and a protective cotton 51 is bonded and connected to the inner side of the fixing clamp 50. The function of the protective cotton 51 is to prevent wear when the fixing clamp 50 clamps the linear array camera 6.

[0036] Among them, an outer support plate 52 is fixedly installed on the surface of the fixing clamp 50, an outer support rod 53 is slidably installed on the inner side of the outer support plate 52, the surface of the outer support rod 53 is fixedly installed on the surface of the positioning box 48, a third spring 54 is slidably sleeved on the surface of the outer support rod 53, two ends of the third spring 54 are respectively fixedly installed on the surface of the outer support rod 53 and the surface of the outer support plate 52, a positioning nut 55 is threadedly installed on the surface of the outer support rod 53, the second motor 45 drives the assembly plate 46 to rotate, and the assembly plate 46 drives its own linear array camera 6 to rotate and take pictures in the tunnel, and the second hydraulic telescopic rod 47 can control the linear array camera 6 to adjust to different positions.

[0037] Furthermore, when the linear array camera 6 needs to be maintained or replaced, the operator controls the positioning nut 55 to rotate and adjust on the surface of the outer support rod 53 to abut against the positioning box 48. At this time, the third spring 54 pushes the outer support plate 52 to drive the fixing clip 50 to slide out on the inner side of the positioning box 48 through the compressed elastic performance. At this time, the L-shaped fixing clip 50 no longer limits the linear array camera 6, so that the linear array camera 6 can be taken out from the inner wall of the groove 49 for maintenance or replacement. When the new linear array camera 6 is placed on the inner side of the positioning box 48, the operator controls the outer support plate 52 to press the third spring 54 on the surface of the outer support rod 53 until the protective cotton 51 on the fixing clip 50 contacts the linear array camera 6, and then the operator controls the positioning nut 55 to descend on the surface of the outer support rod 53 to form a limited fixation on the outer support plate 52 At this time, the linear array camera 6 is positioned and installed after replacement. This method improves the operation method of directly assembling the traditional linear array camera 6 with the assembly plate 46 by means of a fixing component, thereby improving the operation efficiency of the linear array camera 6 being directly positioned and assembled with the assembly plate 46, which is inconvenient for disassembly, maintenance and assembly. The second hydraulic telescopic rod 47 also ensures the convenience of adjusting the linear array camera 6 after positioning it through the positioning box 48, and ensures that the linear array camera 6 and the assembly plate 46 are quickly, conveniently and flexibly installed and used, and reduces the disadvantage that the installation between the linear array camera 6 and the assembly plate 46 occupies a large area, resulting in the inability to add a plurality of sets of linear array cameras 6 for use. The reserved position of the assembly plate 46 can increase the number of linear array cameras 6 and improve the accuracy of combined shooting.

[0038] Furthermore, an extension rod 56 is fixedly installed on the surface of the auxiliary guide plate 43, and a three-dimensional laser radar 7 is fixedly installed on one end of the extension rod 56 away from the auxiliary guide plate 43. The three-dimensional laser radar 7 is used in conjunction with the linear array camera 6.

[0039] Among them, the linear array camera 6 is used to capture the visual information of the inner wall of the tunnel, and provide data support for realizing high-precision tunnel surface reconstruction and tunnel surface disease detection. The three-dimensional laser radar 7 is used to capture the structural information of the inner wall of the tunnel, and provide data support for realizing high-precision tunnel three-dimensional reconstruction and real-time section solution. The annular light source plate 8 is used to provide a supplementary light source for the linear array camera to ensure the consistency of the linear array camera's perception of the environment and facilitate subsequent processing.

[0040] Among them, an auxiliary support plate 11 is slidably installed on the inner side of the positioning support 9, and a positioning clamping rod 12 is fixedly installed on the surface of the auxiliary support plate 11.

The end of the first spring 13 away from the auxiliary support plate 11 is fixedly installed on the inner side of the positioning support 9. A positioning slot 14 is provided on the detection support 5. When the detection vehicle body 1 needs to be replaced for detection and use at different heights during detection in the tunnel, the inspector can control the auxiliary support plate 11 to drive the positioning clamping rod 12 to remove the positioning slot 14 on the detection support 5. At this time, the inspector replaces the detection supports 5 of different heights and installs them for use, so as to facilitate the detection vehicle body 1 to quickly disassemble and install the detection support 5 in different sensitive areas, and the auxiliary wheel frame 41 can be used to achieve height adjustment within a certain range through the first hydraulic telescopic rod 42.

[0041] The detection vehicle body 1 is equipped with an adjustable guide rail system a, which includes a guide rail assembly a1, an adjustable support assembly a2 and a limit device a3; the adjustable support assembly a2 is assembled on the guide rail assembly a1; the limit device a3 is connected to the adjustable support assembly a2.

Then the power block 23 pushes the adjustment plate 22 to drive the power plate 21 to move. The power plate 21 will drive the rotating support rod 15 on the connecting ring 20 to slide. At this time, the rotating support rod 15 will drive the distance between the guide rail ring 16 and the detection vehicle body 1 to be adjusted. This method can be flexibly adjusted for different guide rail distances to meet the deviation of different track spacings when the tunnel track and the detection vehicle body 1 are matched, or the high efficiency of using tracks with different distances, thereby improving the efficiency of using the detection vehicle body 1 in different tunnel environments.
