The invention discloses a combined lifting appliance, which comprises pulley blocks, a main beam, a secondary beam, tundish hooks and a secondary hook, wherein the pulley blocks are connected to the main beam above the main beam and are used for adjusting the height of the main beam; the secondary beam is arranged below the main beam and is detachably connected to the main beam; the tundish hooksare connected to the secondary beam below the secondary beam and are used for hooking a trunnion of a target tundish; and the secondary hook is connected to the main beam, penetrates through a middlehole in the secondary beam and is used for hoisting objects other than the target tundish. Due to the fact that the tundish hooks are connected to the secondary beam which is stably connected to the main beam, during a process of hoisting the tundish, the stability is better, the risk that the high-temperature molten steel in the tundish is spilled out is obviously reduced, and the potential safety hazard of tundish hoisting in an existing steel plant is eliminated.
本发明公开了一种组合吊具,包括滑轮组、主梁、副梁、中间包吊钩和副钩;其中,所述滑轮组在所述主梁上方连接所述主梁,用于调整所述主梁的高度;所述副梁位于所述主梁下方,且可拆卸连接所述主梁;所述中间包吊钩在所述副梁下方连接所述副梁,用于钩住目标中间包的耳轴;所述副钩连接在所述主梁上,且所述副钩穿过所述副梁上的中孔,用于进行所述目标中间包以外的吊装。由于采用在与主梁稳定连接的副梁上连接中间包吊钩,在吊装中间包过程中,稳定性更好,中间包中的高温钢水洒出的风险显著减小,消除现有炼钢厂中中间包吊运的安全隐患。
