Abstract

PURPOSE: To make easy the maintenance of the hydraulic screw-down cylinder, and to shorten the shutdown time of rolling work due to the maintenance of the hydraulic screw-down cylinder, by installing the hydraulic screw-down cylinder and the motor-driven screw-down pressure-block.
CONSTITUTION: In case of taking out the hydraulic screw-down cylinder 8 for the purpose of maintenance or replacement, the rail 5 is lifted up by the screws 3, 3'. Together with the rail 5, the cylinders 8, 8', and motor-driven screw-down pressure- blocks 6, 6', are elevated, leaving a gap between the cylinders 8, 8', and the upper surface of chocks 1, 1'. Next, the hydraulic screw-down pullback cylinder 14 is actuated to extend to pull back the cylinder 8, and at the same time, the motor- driven screw-down pressure-block 6 is moved by the extension of the actuated stroke cylinder 17. The motor-driven screw-down pressure-block 6 and the hydraulic screw-down cylinder 8' together with the rail 5 are moved down by the screw 3, 3', and then, these are placed under the condition ready for the rolling work. During the hydraulic screw-down cylinder 8 is being detached, the motor-driven screw- down pressure-block 6 works instead of the hydraulic screw-down cylinder 8; as a result, the shutdown time of rolling work is shortened.
