Rail robot for routing inspection in tunnel

The invention discloses a track robot for routing inspection in a tunnel, which is used for automatically detecting diseases in the tunnel and removing manual detection cost and detection danger. The rail robot can walk along a preset rail in a tunnel and comprises a walking mechanism, a follow-up support, a stretching mechanism, an information collecting assembly and a controller, and the information collecting assembly is fixed to a stretching rod of the stretching mechanism. When the robot walks along the track, the stretching rod is folded longitudinally, is not limited by space and obstacles, and can quickly reach a designated position. During detection, the extension rod can be transversely unfolded and rotated, and the top of the tunnel can be monitored in a large range. 本发明公开了用于隧道内巡检的轨道机器人，用于对隧道内的病害进行自动检测，去除人工检测成本及检测危险。轨道机器人能够沿隧道内预设的轨道行走，包括走行机构、随动支架、伸展机构、信息采集组件和控制器，信息采集组件固定在伸展机构的伸展杆上。在机器人沿轨道行走时，伸展杆纵向收拢，不受空间和障碍物的限制，能够快速到达指定位置。探测时，伸展杆能够横向展开并旋转，可以实现对隧道顶部一个较大范围的监测。
