Abstract
Description
本発明は、上記のような問題点に着目してなされたものであり、クレーン作業者の技術に依存することなく、傾注樋を破損することなく取り外すことが可能な溶銑傾注樋設備を提供することを目的とするものである。
また、上記の溶銑傾注樋設備は、前記上部台車を移動するための上部台車移動用油圧シリンダを前記下部台車上に設置し、前記下部台車を移動するための下部台車移動用油圧シリンダを前記輸送車両上方の床面上に設置するのが好ましい。
また、上部台車を移動するための上部台車移動用油圧シリンダを下部台車上に設置し、下部台車を移動するための下部台車移動用油圧シリンダを輸送車両上方の床面上に設置したことにより、上部台車及び下部台車の移動システムが簡潔になる。
図1~図3は、本実施形態の溶銑傾注樋設備の全体図であり、図1は正面図、図2は側面図、図3は平面図である。図中の符号1は傾注樋、符号2は出銑樋である。出銑樋2の下端部には溶銑樋先金枠3が取付けられている。図示内高炉から出銑した溶銑は、出銑樋2から溶銑樋先金枠3を通って傾注樋1に注ぎ落とされる。傾注樋1は支持枠4に支持され、この支持枠4をモータ5で回転することにより、例えば図2の時計回り方向、反時計回り方向の何れにも傾動することができる。従って、図2のように傾注樋1を時計回り方向又は反時計回り方向に傾動することで、2台のトピードカー6の何れにも溶銑を注入することができる。なお、本実施形態では、2本の出銑樋2が、傾注樋1の上方で対向配設され、例えば夫々の出銑樋2から交互に溶銑を傾注樋1に注ぎ落とすように構成されている。その結果、傾注樋1を取り外す場合に、そのまま上方に持ち上げたのでは、出銑樋2の溶銑樋先金枠3と干渉してしまう。また、トピードカー6の上方で、且つ傾注樋1が配設されている上部床20には、溶銑が通過する開口部21が開設されている。
