IN-BLAST FURNACE REPAIRING TOOL AND ITS INSTALLATION METHOD

To provide a safety net and its installation method for reducing man-hours required for an operator for installation of the safety net and reducing unsafe work required for the operator.SOLUTION: An in-blast furnace repairing tool according to the present invention is suspended from the upper part of the blast furnace into the blast furnace through a suspension wire. The repairing tool includes a fall prevention member connected to the suspension wire and an expansion member attached to the fall prevention member and into which a pressure medium is introduced. The expansion member is expandable so as to come into contact with the whole periphery of the inner wall of the blast furnace by injecting a pressure medium into the inside of the expansion member.SELECTED DRAWING: Figure 1-1 【課題】設置のために作業者に要求される工数を低減するとともに作業者に要求される不安全な作業を軽減する安全ネット及びその設置方法を提供する。【解決手段】本発明に係る高炉内補修用具は、吊りワイヤーを介して高炉の上部から高炉内に吊り下げられる高炉内補修用具であって、吊りワイヤーに接続される落下防止部材と、落下防止部材に取り付けられ、圧力媒体がその内部に導入される膨張部材とを備え、膨張部材は、圧力媒体がその内部に注入されることによって高炉内壁の全周に接するように膨張可能であることを特徴とする。【選択図】図１−１
