The invention provides a tool for vertically hoisting a coke oven door in a horizontal state and a hoisting method. The tool comprises an ivory arc-shaped lifting lug, a rotary bottom frame and two L-shaped folding hooks. The bottom of the ivory arc-shaped lifting lug is detachably and fixedly connected with the furnace door frame; and the center of gravity of the ivory-arc-shaped lifting lug falls on the perpendicular bisector of the center of gravity of the furnace door and the furnace door lining brick. The rotating bottom frame comprises a bottom plate, two stand columns vertically connected to the bottom plate and a crosspiece. The bent parts of the two L-shaped folding hooks are provided with rotating shafts through rotating shaft holes of the stand columns; a through hole is formed in the short side part of the folding hook corresponding to the pin hole, and a hook groove is formed in the end part of the long side part; the folding hook is locked through the pin and the pin hole after rotating in place on the rotary underframe, and the hook groove hooks the transverse iron on one side of the furnace door. Through cooperation of the ivory-arc-shaped lifting lugs and the rotary bottom frame, the furnace door does not rub and collide with the knife edge and lining bricks of the furnace door in the vertical lifting process, and the furnace door can be well kept vertically in place.

    本发明提供了一种用于焦炉炉门水平状态垂直起吊的工装及吊装方法。所述工装包括:象牙弧形吊耳、旋转底架和两个L形折叠钩。象牙弧形吊耳底部与炉门框可拆卸地固定连接;象牙弧形吊耳的重心点落于炉门与炉门内衬砖整体的重心中垂线上。旋转底架包括底板、底板上垂直连接的两个立柱、以及横档;两个L形折叠钩的折弯部通过立柱的转轴孔设有转轴;折叠钩的短边部对应销孔的位置开有通孔,长边部的端部开有挂钩槽;折叠钩在旋转底架上旋转到位后通过销钉和销孔锁定位置,且挂钩槽钩住炉门一侧的横铁。本发明通过象牙弧形吊耳与旋转底架的配合,使得炉门在垂直起吊过程中既不擦撞炉门刀边及内衬砖,也可以很好地保持炉门垂直就位。
