Description

Technical Field

[0023] like Figure 1 、 Figure 2 and Figure 8As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the walking structure 9 includes mounting frames 901 respectively fixed on the two ends of the lower side of the curved plate 1, and the outer side walls of the mounting frame 901 are fixedly connected to the third motor 902, and the driving end of the third motor 902 passes through the side wall of the mounting frame 901 and is fixedly connected to the mounting shaft 903, and the mounting shaft 903 is fixedly connected to a walking wheel 904, and a guide rail 905 is provided on the lower side of the walking wheel 904, and an auxiliary wheel 906 is slidably connected to the outer side of the guide rail 905, and the auxiliary wheel 906 is rotatably connected to the mounting frame 901; the walking wheel 904 is driven by the third motor 902 to roll on the guide rail 905, and the auxiliary wheel 906 ensures stability during the movement, thereby enabling the position of the curved plate 1 to be automatically adjusted, and the number of guide rails 905 can be increased and spliced, which is convenient for flexible adjustment according to the length of the tunnel, without manual pushing, and can be installed inside the tunnel, thereby facilitating damage detection of the tunnel at any time.

[0024] like Figure 1 and Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the lower end surface of the guide rail 905 is symmetrical and fixedly connected with two adjusting rods 907, and the two adjusting rods 907 are respectively connected with sleeves 908 through bolt assemblies, and a group of through holes are evenly opened on the adjusting rods 907; so that the height of the guide rail 905 can be fine-tuned as needed.

[0027] like Figure 2 、 Figure 4 and Figure 7As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a control box 10 is fixedly connected to the movable plate 3, and a controller 11, an A / D conversion module 12, an alarm 13 and a wireless signal transmission module 17 are respectively installed in the control box 10, the A / D conversion module 12, the alarm 13 and the wireless signal transmission module 17 are respectively electrically connected to the controller 11, the controller 11 is respectively electrically connected to the laser scanner 7 and the first motor 5, and the A / D conversion module 12 is electrically connected to the infrared camera 803; the coordinated work of these components realizes the processing, analysis and transmission of monitoring data. When the laser scanner 7 or the infrared camera 803 detects that the tunnel is damaged, the controller 11 will immediately trigger the alarm 13 and send an alarm message to the relevant personnel. At the same time, it is convenient for outside personnel to intuitively view the damage of the tunnel, thereby improving the intelligence level and response speed of monitoring.

[0028] like Figure 7 As shown, as a preferred embodiment, on the basis of the above method, further, the four corners of the control box 10 are fixedly connected with mounting columns 14, and the mounting columns 14 are connected with sealing plates 15 by bolts; it is convenient to install and disassemble, and convenient for later maintenance.

[0031] Specifically, when the loose accumulation stratum tunnel damage alarm device is used: select the appropriate number of guide rails 905 according to the length of the tunnel, adjust the height of the guide rails 905 according to the size of the tunnel, fix the sleeve 908 in the tunnel, then adjust the adjusting rod 907 and the guide rail 905 to the appropriate height, and then connect the adjusting rod 907 and the sleeve 908 through the bolt assembly, and then splice and build the guide rails 905 in sequence, and then place the walking wheel 904, the auxiliary wheel 906 and the curved plate 1 and other components on the guide rail 905, and then install the stopper 909 at the end of the guide rail 905. When detecting, start the first motor 5 to rotate the walking gear 6 and then cooperate with the arc rack 2 to move the moving plate 3, thereby driving the laser scanner 7 and the infrared camera 803 to move. When the laser scanner 7 detects tunnel damage, it transmits the signal to the controller 11, and the controller 11 controls the alarm 13 to alarm, and at the same time starts the infrared camera 803 to monitor the situation of the damaged part. The infrared camera 803 monitors the situation of the damaged part through A The / D conversion module 12 converts the analog electrical signal output by the infrared camera 803 into a digital signal and transmits it to the controller 11. The controller 11 sends the signal to the terminal via the wireless signal transmission module 17, making it convenient for inspection personnel to remotely check the damage status of the tunnel. When the damage range needs to be checked, the second motor 8013 drives the worm 8014 to rotate, thereby driving the worm gear 8011, the connecting shaft 809, the driving bevel gear 8010, the driven bevel gear 808, the rotating shaft 806 and the pinion 807 to rotate. The rotation of the pinion 807 drives the large gear 805, the connecting shaft 804 and the infrared camera 803 to rotate, realizing precise adjustment of the infrared camera 803 and improving the flexibility and accuracy of monitoring. When damage inspection is required at different locations in the tunnel, the third motor 902 is started to rotate the mounting shaft 903 and the traveling wheel 904, causing the curved plate 1 to move, thereby adjusting the position of the laser scanner 7 and the infrared camera 803, flexibly adjusting the inspection position, and facilitating damage inspection at any time.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
