[0002] Traditional tunnel inspection mainly relies on manual scheduled inspections, which have problems such as low inspection efficiency, high labor intensity, high safety risks, inconsistent inspection standards, and difficulty in inspection at night and in bad weather. For example, although manual foot inspections can more comprehensively discover disease problems, it takes up to 1 hour, and high-speed vehicles in the tunnel pose a huge safety hazard to inspectors; while vehicle inspections are shorter (about 18 minutes), it is difficult to ensure the inspection rate and timeliness, and inspections are prone to be missed.

[0003] By setting sliding tracks on both sides of the tunnel, sliding the inspection robot on the sliding tracks, and then driving the inspection robot with a motor, the inspection robot moves along the sliding tracks. A camera is set under the inspection robot, and the robot can perform real-time inspection of the tunnel during the movement.

[0004] However, during the inspection process, if the battery is low, it is necessary to leave the tunnel immediately for charging. After leaving the tunnel, wait for charging to be completed before conducting an inspection. This cycle is too long and the inspection cannot be carried out at this time. If an abnormality occurs in this section of the tunnel, it cannot be handled in the first time. Summary of the invention

[0025] Reference Figure 1-2As shown, it is a preferred embodiment provided by the utility model, which improves the inspection efficiency and safety index of the inspection robot structure of the tunnel inspection, including a sliding track 200 arranged in the tunnel, the sliding track 200 is provided with an inspection robot 100 for inspecting the tunnel, a pair of sliding columns 102 are arranged at the upper end of the inspection robot 100, the sliding columns 102 are slidably connected to the sliding track 200, a driving structure is installed inside the inspection robot 100, a camera 101 for detecting the tunnel is rotatably arranged at the lower end of the inspection robot 100, a support frame 103 is installed above the sliding track 200, the support frame 103 extends downwardly with a connecting rod 104, a backup power supply 105 is fixedly installed on the connecting rod 104, a telescopic cylinder 106 is fixedly arranged at the lower end of the backup power supply 105, and the output end of the backup power supply 105 is fixedly connected to the telescopic cylinder 106. On the cylinder 106, the output end of the telescopic cylinder 106 is aligned with the charging port of the inspection robot 100. When the inspection robot 100 is conducting an inspection, the camera 101 is provided to perform real-time detection of the tunnel to ensure that any abnormality in the tunnel is handled immediately. When the inspection robot 100 is low on power, the staff operates the inspection robot 100 in the background through the backup power supply 105 set on the sliding track 200 to make it stay on the side of the backup power supply 105, and starts it through the telescopic cylinder 106 on the backup power supply 105, so that the output end of the backup power supply 105 is plugged into the charging port of the inspection robot 100 for charging. After charging is completed, the telescopic cylinder 106 is retracted, and the inspection robot 100 immediately continues to conduct inspections, thereby reducing the technical problem of the inspection robot 100 leaving the tunnel for charging, which causes a long time.

[0026] In this embodiment, a track bracket 300 is provided between the sliding track 200 and the tunnel. One end of the track bracket 300 is fixedly connected to the tunnel by bolts, and the other end is installed on the sliding track 300. Considering the complex terrain such as large bends, long bends and bifurcations in the tunnel, the sliding track 200 is directly installed in the tunnel. The construction difficulty will be greater at the curved position. However, by first setting a track bracket 300 and fixing it in the tunnel, and then fixing the sliding track on the track bracket 300, the construction difficulty will be much smaller.

[0027] In this embodiment, a positioning hole 301 is formed through the track bracket 300, and an inverted L-shaped plate extends from the sliding track 200. The positioning hole 301 allows the track bracket 300 and the inverted L-shaped plate to be fixed together by bolts. In order to fix the track bracket 300 and the sliding track together by bolts, it can be kept fixed during use and is more convenient for inspection and maintenance.

[0028] In this embodiment, a plurality of positioning holes 301 are evenly arranged on the track bracket 300. Considering the existence of large bends, long bends and bifurcations in the tunnel, in order to keep the distance between the sliding track 200 and the tunnel side wall consistent, a plurality of positioning holes 301 are provided. During installation and fixation, construction can be continued through the positioning holes 301 at different positions, thereby achieving the above purpose.

[0029] In this embodiment, streamlined chutes 303 are opened on both sides of the forward direction of the inspection robot 100. The chutes 303 are evenly opened on both sides of the inspection robot 100. Since the tunnel generally has a long distance, the moving time will be very long. The streamlined chutes 303 are opened at both ends of the inspection robot 100, which can reduce air resistance and increase the moving speed of the inspection robot 100, thereby improving the inspection efficiency.

[0030] In this embodiment, the driving structure includes a bidirectional motor 400 fixedly installed inside the inspection robot 100, an active gear 401 is fixedly installed on the output end of the bidirectional motor 400, a sliding column 102 is rotatably connected to the inspection robot 100, and a driven gear 402 is fixedly installed on the sliding column 102. The active gear 401 and the driven gear 402 are meshed and connected. The operator starts the bidirectional motor 400 to drive the active gear 401 at both ends, thereby driving the upper driven gear 402, so that the sliding column 102 moves along the sliding track 200. At the same time, a servo motor is selected in this application. The design and material selection of the servo motor are usually more optimized to achieve higher performance and precision. The servo motor runs smoothly, does not vibrate even at low speed, and has high control accuracy.

[0031] In this embodiment, a rubber ring 403 for increasing friction is provided on one end of the sliding column 102 away from the driven gear 402. The rubber ring 403 is sleeved on the sliding column 102. In order to increase the friction efficiency when the sliding column 102 moves on the sliding track 200, the friction force is increased by providing the rubber ring 403 on the sliding column 102.

[0032] In this embodiment, a barrier ring 404 is provided on one end of the rubber ring 403 close to the driven gear 402 to prevent the rubber ring 403 from being displaced during use. In order to prevent the rubber ring 403 from slowly moving to the other side during the movement, resulting in reduced friction, in this application, the rubber ring 403 is isolated from the outside by providing a barrier ring 404, thereby avoiding the above-mentioned problem.

[0033] In this embodiment, the blocking ring 404 is fixedly connected to the sliding column 102, and the rubber ring 403 is further prevented from moving to one side by the blocking ring 404 being fixed to the sliding column 102. The above description is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
