<p>PURPOSE:To obtain an automatic travelling machine which can pass obstacles without trouble and can travel over a long distance, by arranging a plurality of every set of bearing arms on both sides, and by suspending travelling rollers having guide faces along the side surface shapes of the obstacles, at the tips of the respective bearing arms, to rotate the travelling rollers. CONSTITUTION:In the front and rear of a frame unit 21 for containing a driving source 22 and a controller 23, a plurality of every set of bearing arms 24 on both sides are rotatably fitted. The bearing arms 24 are contrived to be inserted into spaces between both sides by inserting mechanisms 29. Besides, at the tips of the respective bearing arms 24, travelling rollers 26 are respectively fitted to be suspended. On the travelling rollers 26, grooves 26a for a stringing 3 and guide faces 26b with shapes along the side surfaces of iron towers 1 and obstacles are previously formed, and the rollers 26 are rotated by driving rotational mechanisms 28 and are travelled on the stringing 3. As a result, the rollers can pass the obstacles or the like at the apex sections of the iron towers 1 without trouble and can be travelled over a long distance.</p> |
