Abstract

PURPOSE:To carry out the roll chock rearrangement with a few workers, easily in a short time, by installing the chock traveling deck on the chock rearranging truck so as to be movable horizontally and vertically, and by installing the chock table on the chock traveling deck. CONSTITUTION:The chock rearranging truck 1 is moved to the center of the roll table 2 on which the old roll 23 is placed. The chocks 24 are located between the stoppers 22 installed on the upper surface of the chock table 15. The inner wall 8' of the chock traveling deck 8 is lifted until the chock table 15 strikes the bottom face of the chock 24. Next, by retreating the chock traveling deck 8 with the cylinder 11, the chock 24 is pulled away from the old roll 23. Meanwhile, in case of inserting the chock into the new roll 25, the rearranging truck 1 is transferred to the position of the roll table 2 for placing the new roll 25. The movements of the rearrangement truck 1 and the traveling deck 8 are adjusted in order to make coincidence between the center of the new roll 25 and the center of the chock on the table 15. Then, by moving the traveling deck 8 forward with the cylinder 11, the chock is pushed by the stopper 22 into the shaft of the new roll 25.
