Provided is a magnetic encoder device capable of detecting a rotating angle of an actuator having a cavity structure. The magnetic encoder device includes a ring-shaped rotating body, a ring-shaped permanent magnetwhich is inscribed in and fixed to an inner circumferential side of the ring-shaped rotating bodyand magnetized in a direction perpendicular to a center axis of the rotating body, and a fixed bodywhich is disposed on an inner circumferential side of the permanent magnetthrough an air gap and has a circular circumference and a cavity, and a magnetic field detecting elementdisposed on an outer circumferential side of the fixed bodythrough the permanent magnetand the air gap.

Magnetic encoder device and actuator

A robot vehicle for hot-line job for transmission and distribution lines which comprises an insulating boom formed of an insulating material at a tip end stage of multiple stage booms, a base end of which is supported on an elevated work vehicle to be capable of swinging, pivoting up and down, and extending and contracting, and a frame provided on the tip end of the insulating boom, the frame mounting thereon double arm manipulators of multishaft construction for performing a distribution work, a slide device for sliding independently these right and left double arm manipulators front to rear, and lifting arms of multishaft construction having a function of lifting a heavy article, so as to allow an operator to perform remote control. An electric actuator is used for driving the double arm manipulators and the slide device, and hydraulic manipulators for driving the lifting arms. Accordingly, a robot vehicle for hot-line job is provided to mount thereon a third arm which enables highly accurate positioning of the manipulators, remote control by an operator and automatic operation through a teaching-playback, has a function of lifting a heavy article, and is small-sized and lightweight.
