摘要
针对海上风机叶轮大型基础钢桩的安装作业,进行了一种单边夹持吊具的研究,能够实现大型基础钢桩的海上吊装操作。首先,进行了单边夹持吊具的结构设计并阐述了工作原理;其次,分析了吊具夹紧受力状态,研究了液压缸凸轮与自重凸轮夹紧机构,进行了夹紧力分析;最后,研制了模型样机并进行了吊桩实验,验证了方案设计的合理性与可靠性,为工程样机的设计打下了理论与实践基础。
A unilateral clamping suspension tool was researched for tube stake installation of marine fan impeller and it is able to lift great steel tube stake. First of all, it carried out the structural design of the suspension tool and described the its working prin- ciple ; Secondly, the force state of suspension tool clamping was analyzed and the hydraulic and the dead load cam clamping mech- anism were designed and also analyzed the clamping force ; Finally, it developed the prototype and carried out hanging tube experi- ments to verify the rationality and reliability of the design of prototype and lay the theoretical and practice foundation for the de- sign of engineering prototype.
