<p><P>PROBLEM TO BE SOLVED: To perform self-traveling inside piping provided in a perpendicular direction, with simple configuration. <P>SOLUTION: At one end side of a device body 1, a first link 4 is provided which is inclined by being expanded to the outside in a radial direction, while abutting a first wheel 3 in a distal end thereof to an inner surface of piping. At another end side of the device body 1, a second link 7 is provided which is inclined in the same direction as the first link 4 by being expanded to the outside in the radial direction, while abutting a second wheel 6 in a distal end thereof to the inner surface of the piping A. The first link 4 and the second link 7 are connected by a connecting link 8. A movable ring 10 is provided which is movable in an outer circumference of a shaft 9 extending to the other end of the device body 1, and the movable ring 10 and the second link 7 are connected by a third link 12. Between the movable ring 10 and an end portion of the shaft 9, a push spring 15 is disposed which moves the movable ring 10 and expands the second wheel 6 of the second link 7 outward via the third link 12, and a motor 19 is connected to the first wheel 3 via a reduction drive. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
