The invention discloses a multi-stage shaking-prevention fixing lifting device of a ladle crane. The ladle crane, a lifting rope, a four-rod positioning frame, a lifting block, a fixed ring, a guide sleeve, a spring A, a fixing sleeve I, a rotating shaft I, a connecting block I, a reinforcing base I, a spring B, a fixing sleeve II, a rotating shaft II, a connecting block II, a reinforcing base II,a spring C, a reinforcing rod, a hook, and a placing bucket are included, firstly, through positioning design, the lifting work of the lifting rope is not affected while the freedom degree of the lifting rope is limited, the phenomenon that the lifting rope drives the placing bucket below the lifting rope to generate great shaking can be effectively avoided, therefore, high-temperature molten steel overflow problem can be solved, then, in cooperation with an elastic multi-angle limiting structure, the damping effect is achieved through a springback mechanism, the counter-acting force to the placing bucket in the process of pouring out molten steel can be reduced, whole stability of a lifting part can be improved, finally, an electric clamping manner is adopted, therefore, the anti-shakingeffect of the lifting part can be further reinforced, it is ensured that the shaking range is within the controllable range, and the side turning can be solved.
本发明公开了一种铸造起重机多级防摇晃固定吊装器,包括铸造起重机和起吊绳、四杆定位架、吊装块、固定环、导向套、A弹簧、I固定套、I转轴、I连接块、I加固座、B弹簧、II固定套、II转轴、II连接块、II加固座、C弹簧、加固杆、挂钩、放置桶,首先通过定位设计,在限制起吊绳自由度的同时,也不影响起吊绳起吊作业,有效防止起吊绳带动下方放置桶产生较大晃动,造成高温钢水外溢的问题,其次配合弹性多角度限位结构,也能通过回弹机构达到减震作用,降低放置桶在倒出钢水过程中所受到的反作用力,提高吊装部件整体的稳定性,最后因采用电动夹持方式,因此也能够进一步加强吊装部件的防摇晃作用,确保摇晃范围在可控范围内,避免侧翻等问题。
