PROBLEM TO BE SOLVED: To dispense with swing of a lifter body in a coke oven direction, swirling of an opening of a coke oven chamber in a direction of twisting around a central line in the coke oven direction, and their return control, and dispense with measurement of a displacement amount and resetting of a control amount again even with further changes over the ages.SOLUTION: Hooks 12a and 12b for supporting a bar 53 of a furnace cover 52 are provided on the front face of a lifter body 3 so as to lift up and down freely by a cylinder device 14. A lifter body 3 is installed on the front face side of the frame 2 so as to enable of permission of swing and centering in a coke oven direction, swing in an incinerator length, and permission of swirling and centering of an opening 51 of a coke oven chamber in a direction of twisting around a central line in the coke oven direction. A cylinder device 15a of a lock device 15 for preventing swing in the coke oven direction and the incinerator length, and swirling of the opening of the coke oven chamber in a direction of twisting around the central line in the coke oven direction, of the lifter body 3 with respect to the frame 2 is installed swingably in the coke oven direction so that the centering state can be kept by an elastic member.SELECTED DRAWING: Figure 1 |
