The invention belongs to the technical field of ships, and discloses a suspension arm structure and a heavy lift ship. The lifting arm comprises a lifting arm body and a push-pull device, a conical end is arranged at the front end of the lifting arm body, the conical end is inserted into an opening of an outer plate of a ship body, a hooking position is formed at the front end of the conical end, the push-pull device is installed in the ship body and comprises a telescopic rod, a connecting piece and a hook, the telescopic rod is connected with the hook through the connecting piece, and the hook can be hooked to the hooking position. The telescopic rod is inserted into the air cylinder, the air cylinder pushes the telescopic rod to reciprocate, and the telescopic rod drives the hook to reciprocate in the inserting direction of the suspension arm body; the problems that in the prior art, when a lower suspension arm is inserted into an opening in a ship body outer plate, the insertion process is strenuous, and the lower suspension arm is prone to being stuck are solved.
本发明属于船舶技术领域,公开了一种吊臂结构及重吊船。其中包括吊臂主体和推拉装置,吊臂主体前端设置有锥形端,锥形端插接在船身外板的开孔内,锥形端前端形成有钩接处,船身内安装有推拉装置,推拉装置包括伸缩杆、连接件和挂钩,伸缩杆通过连接件与挂钩连接,挂钩能钩接在钩接处上,伸缩杆插接在气缸内,气缸推动伸缩杆往复移动,伸缩杆带动挂钩沿吊臂主体插接方向往复滑动;解决现有技术下吊臂插接在船身外板上的开孔的时候,插接过程较为费力,容易卡死的问题。
