傷を付ける難点がある。In any case, the cable laying vehicle is designed to be self-propelled in the sewer pipe under remote control from the outside. In such a cable-laying vehicle, the wheels, including the drive wheels, are made of rubber tires, but the inner surface of the sewer pipe is slippery and extremely slippery due to dirty water, oil, mold, etc. However, if there are many steps in the pipeline, you may not be able to overcome it. Some wheels have wheels formed with abrasive grains to prevent them from slipping, but when the wheels run idle, there is a problem that the inner wall of the pipe is damaged.

走行可能となる。In the invention according to claim 2, the spike wheel of the invention according to claim 1 is mounted so as to be able to move forward and backward,
It is characterized in that the reciprocation is performed by an actuator, for example, a hydraulic cylinder. According to the present invention, when the rubber tire cannot slip and run, the spike wheel is moved forward by the actuating device so as to project laterally and pressed against the inner wall of the pipe. As a result, the spike wheel can roll on the inner wall of the pipe to run.
