Background

When an operation is performed in a furnace such as a melting furnace or a combustion chamber, refractory materials and furnace accretions (clinker, dust pieces, etc.) that have degraded from the upper part of the furnace fall down, and there is a concern that the operator is injured by the falling refractory materials and the like. Therefore, conventionally, it has been common to visually confirm whether or not an object that is likely to fall is present before an operator enters the furnace, to exclude the risk of the object being likely to fall by a special tool, to enter the furnace, to assemble a temporary scaffold, to inspect the temporary scaffold, and to perform maintenance work. However, in such a conventional method, in addition to the time required for starting the in-furnace inspection and maintenance work, the operation of assembling the temporary scaffold in the furnace is also required in terms of safety, and in the conventional method, an airbag is provided in the furnace instead of assembling the temporary scaffold, and in the conventional technique, the airbag is placed on the support member to prevent falling by inflation, and when inflated, the outer side surface of the airbag is closely attached to the inner wall of the furnace, but the adhesion force (tension) is small, and in this case, when a heavy falling object falls on the upper portion of the furnace, the falling object is temporarily blocked by the airbag, but moves to the outer side surface side of the airbag in accordance with the shape of the upper surface of the airbag, and thus, since the adhesion force of the outer side surface of the airbag to the inner wall of the furnace is small, when the adhesion force is smaller than the weight of the falling object, the falling object may slip down between the outer side surface of the airbag and the inner wall of the furnace to the lower side of the balloon, and the safety hazard to an operator who performs the inspection and maintenance work under the balloon is caused.
