The invention relates to a crane boom frame of a full-rotation crane ship, which comprises a main beam and an auxiliary beam, the main beam is connected with the auxiliary beam through a rolling shaft, the rolling shaft on the auxiliary beam moves along the main beam so as to assist the main beam in supporting a hoisted object, and self-locking is formed through an extension type self-locking mechanism on the rolling shaft. Compared with an existing full slewing crane or crane, the crane boom provided by the invention has the advantages that the load of a hoisted object is distributed to the two independent main beams and auxiliary beams, the slewing radius and tonnage of the hoisted object are improved in the forward hoisting operation process of a crane ship, and meanwhile, the operation safety is improved.

    本发明涉及一种全回转起重船的起重臂架,包括主梁、辅梁,所述主梁与辅梁通过滚轴连接,所述辅梁上的滚轴沿着主梁移动,从而辅助主梁吊物的支撑,并通过滚轴上的延伸型自锁机构形成自锁。本发明提供的起重臂架,与现有的全回转起重机或者起重机的起重臂架相比,被吊物载荷被分配到两个独立的主梁以及辅梁上,在起重船进行正吊作业过程中,提高了被吊物的回转半径以及吨位,同时提高了作业的安全性。
