用于吊装扭王字块的便携式吊装装置研发

扭王字块作为护面结构广泛应用于沿海及近海防波堤工程中，块体预制须在临时或专业预制场地进行，预制数量往往很大，提高块体预制效率和节约成本成为关键的问题。结合东营港广利港区南、北防波堤工程实例，针对扭王块预制过程中场地内块体倒运环节研发出一种装载机吊装扭王字块的便携式吊装装置。此装置具有投入配合机械数量少、倒运效率高、场地占用面积小、操作灵活等诸多优点，大大提高了块体场地内转运效率，且在一定程度上节约了施工成本。

Research and development of portable hoisting device used for lifting accoropode

As a protective structure,the accropode is widely used in coastal and offshore breakwater projects.The prefabrication of the accropode needs to be performed in a temporary or professional prefabricated site.The number of prefabricated blocks is often large,so the improvement of block prefabrication efficiency and cost saving have become key issue.In this paper,based on the examples of the south and north breakwater projects in the Guangli Port District of Dongying Port,a portable lifting device for lifting the accropode by a loader is introduced for the block reverse movement in the prefabricated process of the accropode.Many advantages,such as small quantity,high efficiency of reverse transportation,small area occupied by the site,flexible operation,etc.,have greatly improved the transfer efficiency in the accropode site and saved construction costs to a certain extent.
