Application: Magnetically-attracting crawler moving device, multi-connected magnetically-attracting crawler moving device, and generator inspection robot (Patent ID: US20230406427A1)

The patent filed by Mitsubishi Electric Corp describes a magnetically-attracting crawler moving device that includes a source device of magnetic force with a pair of magnets and a yoke, a non-magnetic guide, and a crawler belt that runs along the guide without direct contact with the magnets. The design allows the crawler belt to protrude from the source device of magnetic force and the guide for movement.

The claims detail the specific configurations and materials used in the magnetically-attracting crawler moving device, such as the use of engineering plastic for the guide, the arrangement of magnets with opposite polarities, and the inclusion of multiple magnets along the running direction of the crawler belt. Additionally, the patent covers the integration of multiple crawler moving devices for parallel or series connection, as well as the application of the device in a generator inspection robot for navigating tight spaces between generator components. The design of the device allows for efficient and controlled movement in various industrial applications.
