Abstract

PURPOSE:To replace rolls rapidly, by drawing out a roll replacing dolly mounting a roll in the direction perpendicular to a pipe manufacturing line with the aid of a traction dolly and replacing the former with a replacing dolly mounting a spare roll. CONSTITUTION:Engagement between a mill housing 2 and a roll box 6 is released by moving upper and lower pressing-down screws of the housing 2 to the direction apart from the roll box 6 after releasing the connection between a roll shaft and a spindle 35. Next, a roll replacing dolly is lifted onto a rail 24 from a rail 3 by driving a traction dolly 26. A pin 31 of a connecting fitment 29 is detached by rocking an hydraulic cylinder 30 to release the connection between both the dollys 4 and 26. Next, a dolly 23 is moved to the direction of a pipe manufacturing line to replace the dolly 4 mounting a spare roll instead of the dolly 4 lifted before, and the replaced dolly is connected to the dolly 26 again to move them to the rail 3 from the rail 24 by a driving device thereby returning them to the original position to perform the roll replacing.
