摘要： PROBLEM TO BE SOLVED: To safely and efficiently execute the pulling-out work by providing a nozzle pulling-out mechanism, a profiling mechanism for absorbing any dislocation in the front and the rear, the right and the left, the upper and the lower directions with one mechanism and a shifting mechanism for shifting a supporting table to a prescribed position to a ladle for incorporating molten metal. SOLUTION: At the time of sliding a pulling-out rod 15 forward by falling down a pulling-out jig 17 parallel to the pulling-out rod 15 and introducing air pressure or oil pressure from a connector 13, since the pulling-out rod 15 in the nozzle pulling-out mechanism 2 does not coincide With a nozzle hole of the ladle for incorporating the molten mold, the pulling-out rod 15 receives the inserting resistance from the nozzle hole. The profiling mechanism 3 is worked with this resistant force and the dislocation in the vertical direction is absorbed by rotating a link ball and a spherical surface bush around center of each ball and the dislocation in the horizontal direction is absorbed by sliding in the front and the rear directions with the spherical surface bush and a spring post. Further, reaction can be made to receive with a cylindrical body.

摘要： PROBLEM TO BE SOLVED: To reduce excessive force of vibration, etc., transmitted to a robot by giving eccentric oscillation to a burner with an oscillating mechanism and and having a link mechanism having an oscillating shaft oscillatable in plural directions. SOLUTION: In the refractory deposit oxygen cleaning device 20, solidified metal is burned and blown off by an oxygen cleaning burner 121. A burner support/rocking mechanism 23 supports the burner 121 and undertakes eccentric rocking thereon. These are mounted on a frame 4. The burner support/rocking mechanism 23 is arranged with a link mechanism 26 to support the oxygen cleaning burner 121 and an oscillation mechanism 127 to eccentrically rock. The oxygen cleaning burner 121 is rockably supported by the link mechanism 26 in up/down and left/right by regarding a virtual point 128 (target point) as an apex. Thereby the working reaction force transmitted to a tool main body can be received.
