In the present invention, in order to solve the above-mentioned problem, the train line inspection device 1 is configured to run on two suspension lines M that are installed substantially horizontally and substantially parallel to each other above the trolley wire T. I do. At least four traveling rollers 3 driven by motors 4 and 5 are provided on the front and rear and left and right sides of the frame 2 of the trolley line inspection device 1 so as to roll on the suspension line M, and are positioned below the suspension line M during traveling. Then, a pressing roller 6 that rolls on the lower surface of the suspension line M is provided. The base end side of the arm 7 supporting the holding roller 6 is rotatably supported on the frame 2, and the arm 7 is rotated between the holding position and the retracted position by arm driving means including an arm driving motor 10. The arm 7 hangs substantially perpendicularly to the frame 2 at the holding position, arranges the holding roller 6 below the suspension line M, stands up almost vertically at the retreat position, and moves the holding roller 6 to the side of the frame 2. Deploy. An obstacle on the traveling path is detected by the obstacle sensors 14, 15, 16 and based on the obstacle detection information from the sensors 14, 15, 16, the controller 17 controls the arm drive motor 10, which is the arm drive means, 11 is controlled.
The trolley wire inspection device 1 self-propells on the suspension line M with the traveling roller 3 and moves along the suspension line M, and performs various inspections of the trolley line using an inspection device such as an eddy current sensor 18 mounted thereon. If there is an obstacle crossing the course during traveling, the obstacle sensors 14, 15, 16 sequentially detect this, and based on the detection signal, the arm drive motor 10 as the arm drive means and the clutch 11 operate. By rotating the arm 7 outward, traveling is continued smoothly while avoiding obstacles. Since the arm 7 sequentially retreats back and forth as it progresses, one of the front and rear pressing rollers 6 always holds the suspension line M from below.
