The invention belongs to the field of cranes, and discloses a cargo boom self-unloading device, a cargo boom self-unloading method and a roof crane. The cargo boom self-unloading device comprises an adapter bracket and a lifting lug structure; the adapter bracket is provided with a mounting end and a bearing end which are oppositely arranged, the mounting end is used for being detachably mounted on the bearing arm section, and the bearing end is used for bearing a lifting rope; the lifting lug structure is used for being detachably installed on the arm section to be disassembled, and the lifting lug structure is used for locking the lifting rope. According to the cargo boom self-unloading device provided by the invention, during disassembly, only the connecting pin shaft between the to-be-disassembled boom section and the bearing boom section needs to be disassembled, and the to-be-disassembled boom section can be downwards lifted and disassembled through the lifting movement of the lifting rope, so that the self-unloading operation of the cargo boom is realized, the working hours of external lifting and disassembling equipment do not need to be occupied, and the working efficiency is improved. And therefore, the operation is simple and reliable, and resources are saved.

    本发明属于起重机领域,公开了一种起重臂自卸装置、起重臂自卸方法及屋面起重机。起重臂自卸装置包括转接支架以及吊耳结构;所述转接支架具有呈相对设置的安装端与承载端,所述安装端用以可拆卸地安装至所述承载臂节上,所述承载端用以承载起升绳;所述吊耳结构用以可拆卸地安装至所述待拆卸臂节上,所述吊耳结构用以供所述起升绳锁紧。在本发明提供的起重臂自卸装置中,在进行拆卸时,只需要卸开所述待拆卸臂节与承载臂节之间的连接销轴,即可以通过所述起升绳的起升活动将所述待拆卸臂节下吊拆卸,以此实现所述起重臂的自卸操作,无需占用外界吊拆设备的工时,只需要逐节拆卸至合适的长度即可,操作简单可靠,节省资源。
