Description

Technical Field

[0001] The present application belongs to the technical field of highway tunnel inspection, and in particular, relates to a highway tunnel inspection device. Background Art

[0002] Compared with ordinary roads, expressways have the characteristics of fast driving speed, large traffic capacity and fully closed management and operation. The road infrastructure and road safety facilities are relatively complete. They bear a huge passenger and freight transportation volume and are the main artery of road transportation. Tunnels, as an important part of expressways, have the characteristics of complex structure, closed environment, poor ventilation and lighting conditions. In order to ensure the normal use of internal facilities of expressways, daily inspections are usually required inside expressway tunnels. However, manual inspections are inefficient and labor-intensive, and the inspection frequency is limited. Therefore, expressway tunnel inspectors are used in conjunction with cameras or radars to conduct fast and efficient inspections inside expressway tunnels.

[0003] The utility model with the existing authorization announcement number CN219013842U discloses a tunnel inspection robot, including a guide rail and a robot body installed on the guide rail; the robot body includes a shell, a walking unit, a pan-tilt unit and a power supply unit; the walking unit includes two driving wheels symmetrically arranged on both sides of the guide rail, the driving wheels are connected to a driving motor, and the driving wheels are attached to the guide rail and slide along the length direction of the guide rail.

[0004] By adopting the above technical scheme, a charging unit is set on the robot body, which realizes automatic charging of the robot body and long-term and long-distance operation of the robot body, thereby improving the inspection quality and efficiency. However, in the above technical scheme, the highway tunnel patroller is powered by a battery when in use. In the case of a long highway tunnel, a larger battery is required to ensure that the patroller can inspect the entire highway, which greatly increases the load of the highway tunnel patroller and thus increases the power consumption of the highway tunnel patroller, forming a vicious circle. In addition, a larger battery also requires a longer charging time, resulting in the highway tunnel patroller being unable to inspect the highway tunnel multiple times in a short period of time, affecting the inspection efficiency of the highway tunnel patroller. Moreover, the battery capacity will decay after long-term use, thereby further shortening the inspection time of the highway tunnel patroller. At the same time, replacing the battery also increases the subsequent maintenance cost of the highway tunnel patroller.

[0005] To this end, we propose a highway tunnel patrol device to solve the above problems. Utility Model Content

[0033] The working principle of the utility model is as follows: when in use, the two guide rails 1 are first spliced ​​together by using the splicing groove 11 in conjunction with the splicing block 12 and the splicing hole 13, and the spliced ​​guide rails 1 are fixed inside the highway tunnel by the splicing bolts 14, and then the conductive copper sheets 3 on the two different guide rails 1 are butted and fixed together by the butt groove 15 in conjunction with the butt block 16 and the butt bolts 17. At this time, the two conductive copper sheets 3 can be connected to the live wire and the neutral wire of the power supply by the conductive copper sheet 3 in conjunction with the guide rail 1, and then the conductivity of the carbon slide plate 7 can provide power for the highway tunnel patrol device at all times. There is no need to use batteries to power the highway tunnel patrol device, and there is no need to charge the highway tunnel patrol device, which effectively reduces the weight of the highway tunnel patrol device, allowing the highway tunnel patrol device to conduct multiple inspections of the highway tunnel in a short time, avoiding many disadvantages of battery power supply to the highway tunnel patrol device, and effectively ensuring the inspection efficiency of the highway tunnel patrol device. In addition, the elastic force provided by the compression spring 5 and the ceramic sheet 6 can push the carbon slide plate 7 to move upward and always maintain contact with the conductive copper sheet 3 to ensure the smooth transmission of electrical energy. And the upward thrust of the compression spring 5 can compensate the wear of the carbon slide plate 7 and the conductive copper sheet 3 to a certain extent, so that the arc is not easy to appear between the carbon slide plate 7 and the conductive copper sheet 3 due to the gap, and the ceramic sheet 6 can further extinguish the arc. Through the contact between the insulating plate 8 and the sponge block 9 and the conductive copper sheet 3, the dust on the surface of the conductive copper sheet 3 can be cleaned as the highway tunnel patrol device moves, thereby increasing the service life of the highway tunnel patrol device, ensuring that the highway tunnel patrol device can work normally for a long time, and also reducing the later maintenance cost of the highway tunnel patrol device. Finally, the power provided by the servo motor 22 cooperates with the support plate 20 to drive the sliding wheel 21 to slide inside the auxiliary groove 19, and cooperates with the sliding of the limit plate 23 and the auxiliary wheel 24 inside the auxiliary groove 19 to ensure that the highway tunnel patrol device can move back and forth smoothly on the guide rail 1. The camera 26 cooperates with the radar 25 to ensure the normal inspection of the highway tunnel patrol device. The signal transceiver module 27 can transmit the data collected by the camera 26 and the radar 25 to the remote control room by wireless mode, so that the highway tunnel patrol device can perform the inspection work normally.
