The invention provides a connecting joint, an auxiliary arm mechanism and a crane, relates to the technical field of crane equipment, and aims to optimize the structure of the connecting joint to a certain extent and reduce the disassembly and assembly frequency among structures in the auxiliary arm mechanism. The connecting joint is used for connecting a main arm and an auxiliary arm mechanism and comprises a frame body, and the frame body comprises a first supporting rod, a second supporting rod and a third supporting rod; the two ends of the second supporting rod are connected with one endof the first supporting rod and one end of the third supporting rod correspondingly, and a first connecting part is formed at the joint of the second supporting rod and the third supporting rod and used for connecting a lower knuckle arm of the auxiliary arm mechanism; a second connecting part is arranged on the first supporting rod and used for being connected with a first mast of the auxiliary arm mechanism; a third connecting part is arranged on the second supporting rod and used for being connected with a second mast of the auxiliary arm mechanism; and fourth connecting parts are formed atthe ends, away from the second supporting rod, of the first supporting rod and the third supporting rod and used for connecting the main arm.

    本发明提供的一种连接节、副臂机构及起重机,涉及起重机设备技术领域,以在一定程度上优化连接节的结构,降低副臂机构中的各结构之间的拆装频率。本发明提供的连接节,用于连接主臂和副臂机构,包括架体,架体包括第一支杆、第二支杆以及第三支杆;第二支杆的两端分别与第一支杆和第三支杆的一端相连接,且第二支杆与第三支杆的连接处形成有第一连接部,第一连接部用于连接副臂机构的下节臂;第一支杆上设有第二连接部,第二连接部用于连接副臂机构的第一桅杆;第二支杆上设有第三连接部,第三连接部用于连接副臂机构的第二桅杆;第一支杆与第三支杆远离第二支杆的一端均形成有第四连接部,第四连接部用于主臂相连接。
