して煉瓦積み作業を自動的に行うものである。For this reason, the present inventors have proposed that a small industrial robot should be used instead of a hand crane to carry out an efficient furnace construction work with good results. That is, as shown in FIG. 1, a furnace construction apparatus using this robot includes a circular turning rail 1, a turning carriage 2 movably attached to the turning rail 1, the turning carriage 2, and the turning rail. A traverse rail 3 arranged so as to connect the centers of 1 and the traverse rail 3
And a small robot 5 for furnace construction suspended from the lower portion of the traverse carriage 4. When using this furnace-building device, as shown in FIG. 2, the whole furnace-building device is hung in the furnace from the pedestal 7 installed on the upper part of the converter 6 by the elevating device 8, and the bricks are robotized by the robot. The bricks are loaded on the circumference, and the robot is automatically swung, traversed, and moved up and down to perform brick-laying work.
