The invention relates to the technical field of ocean platform cranes, and discloses a mechanical arm for an ocean platform crane, the mechanical arm comprises a mounting seat and a truss main arm fixed on the mounting seat, the truss main arm comprises three parallel spindles distributed in an isosceles triangle shape; the three main shafts are fixedly sleeved with a plurality of isosceles triangular plates distributed at intervals in a one-to-one correspondence mode, and the angles between the adjacent isosceles triangular plates and the same main shaft are complementary. Through the design of the branch arms, the auxiliary shafts are also triangularly distributed, the stability of the branch arms can be improved, the structure is simple, the weight can be effectively reduced, the structure is stable, and the load capacity can be improved.
本发明涉及海洋平台起重机技术领域,公开了一种海洋平台起重机用机械臂,包括安装座和固定在所述安装座上的桁架主臂,所述桁架主臂包括三个平行且呈等腰三角分布的主轴,三个所述主轴上一一对应固定套接有多个间隔分布的等腰三角板,相邻的所述等腰三角板与同一个所述主轴之间的角度互补。本发明通过分臂的设计,副轴也呈三角分布,能够提高分臂的稳定,且结构简单能够有效降低重量,结构稳定能够提高负载能力。
