APPARATUS FOR AUTOMATICALLY SEPARATING OR CONNECTING LUBRICATION OIL SUPPLY HOSES TO ROLL CHOCKS FOR ROLLING MILL TO PROTECT WORKERS FROM SAFETY ACCIDENT

摘要

PURPOSE: To provide an apparatus for connecting lubrication oil supply hoses to roll chocks for rolling mill, wherein the apparatus not only shortens replacement operation time, but also protects workers from safety accidents by separating the lubrication oil supply hoses from the roll chocks or connecting the lubrication oil supply hoses to the roll chocks by operation of cylinders when performing replacement operation of back up rolls. CONSTITUTION: The apparatus for connecting lubrication oil supply hoses to roll chocks for rolling mill comprises a lubrication oil supply ports(21a,21b) respectively formed on upper and lower surfaces of roll chocks(20a,20b) that support back up rolls(10a,10b); lubrication oil supply pipes(31a,31b) installed on the inner surface of an equalizer beam(30a) and a slide(30b) in such a way that the lubrication oil supply pipes are selectively connected to the lubrication oil supply ports; and a supply hose connecting means(50) installed on one side surface of the equalizer beam and the slide in such a way that the supply hose connecting means is selectively connected to the lubrication oil supply pipes.
