Abstract
A magnetically-attracting crawler moving device has a magnetically-attracting traveling mechanism including a source device of magnetic force provided with a pair of magnets and a yoke disposed on the backside of the magnets or behind the magnet; a crawler belt rotationally running with drive portion thereof in non-contact with the source device of magnetic force; and a guide in contact with the pair of magnets and the yoke and on which surface the crawler belt slides, wherein the drive portion of the crawler belt protrudes from the source device of magnetic force and the guide to travel.
Claims20
A magnetically-attracting crawler moving device comprising:
- a source device of magnetic force including a pair of magnets each arranged such that polarities of magnets are opposite to each other and including a yoke disposed in contact with each magnet of the pair of magnets;
- a non-magnetic guide disposed so that different sides of the guide is in contact with each magnet of the pair of magnets and a bottom of the guide is in contact with the yoke, or the bottom is in contact with the pair of magnets and the different sides are in contact with the yoke;
- and
- a crawler belt rotationally running in non-contact with the source device of magnetic force and along the longitudinal direction of the guide.
A magnetically-attracting crawler moving device comprising:
- a source device of magnetic force including a pair of magnets each arranged such that polarities of magnets are opposite to each other and a yoke pair disposed sandwiching the pair of magnets,
- a non-magnetic guide made of engineering plastic, having a bottom disposed in contact with an upper surface of the pair of magnets, and sandwiched between the yoke pair, and
- a crawler belt rotationally running in non-contact with the source device of magnetic force and along the longitudinal direction of the guide, wherein the crawler belt projects from the source device of magnetic force and the surface of the guide and runs rotationally while sliding on a surface of the guide.
A generator inspection robot comprising:
- a magnetically-attracting crawler moving device including:
- a source device of magnetic force including a pair of magnets each arranged such that polarities of magnets are opposite to each other and including a yoke disposed in contact with each magnet of the pair of magnets;
- a non-magnetic guide disposed so that different sides of the guide is in contact with each magnet of the pair of magnets and a bottom of the guide is in contact with the yoke, or the bottom is in contact with the pair of magnets and the different sides are in contact with the yoke;
- and
- a crawler belt rotationally running in non-contact with the source device of magnetic force and along the longitudinal direction of the guide;
- and
- an inspection robot body equipped with a check and/or an inspection instrument;
- connecting legs adapted to connect the at least one crawler device with the inspection robot body so as to be able to adjust relative positions of the at least one crawler device and the inspection robot body,
- wherein the at least one crawler device, the inspection robot body, and the connecting legs are integrated to be able to travel as the whole in a gap space between a stator and a rotator of a generator.
