Abstract:
To improve maintainability.SOLUTION: A vibration control device 1 includes: a base 3; a guide device 4; a moving frame 5 which is held by the guide device 4 so as to reciprocate; a linear motor 6; a moving mass 2 mounted on the moving frame 5; and a jack-up point 7 provided on the moving mass 2. The moving frame 5 is equipped with frame divided bodies 8a, 8b, and 8c divided into plural pieces. The linear motor 6 is equipped with a common stator 9 mounted on a base 3; and a plurality of movable elements 10a, 10b, and 10c individually mounted on the frame divided bodies 8a, 8b, and 8c. When the maintenance of the vibration control device 1 is performed, the moving mass 2 is jacked up, and the frame divided bodies 8a, 8b, and 8c are drawn out from a lower side of the moving mass 2, thereby allowing a worker to approach the frame divided bodies 8a, 8b, and 8c and the corresponding movable elements 10a, 10b, and 10c.SELECTED DRAWING: Figure 1
