Description

Lifting frame for ship dismantling Technical Field The utility model belongs to the technical field of ship construction equipment, and particularly relates to a lifting frame for ship disassembly. Background When the ship multi-deck, mast and other high-altitude structures need to be disassembled, the lifting frame can provide a stable high-altitude operation platform, so that workers can be prevented from climbing dangerous structures, and falling risks are reduced. Publication number CN221343785U, this crane is repaired to boats and ships have solved the regulation elevation that current equipment can not be convenient, and messenger's equipment that can be convenient moves and the locking is fixed, and holds the structure and take place to rock or drop, can not protect holding the structure drop, influence the problem of the security and the stability that equipment used, but lift support arm expansion angle lacks effective limit structure, easily leads to the crane unbalance, exists the potential safety hazard. In view of the above, a crane for ship dismantling has been proposed, which is improved against the conventional drawbacks. Disclosure of utility model The utility model aims to provide a lifting frame for ship dismantling so as to solve the problems in the prior art. The lifting frame for ship dismantling comprises a bearing table and a frame body, wherein the frame body is fixed below the bearing table and is movably connected with one end of a lifting support arm through a middle connecting component, the other end of the lifting support arm is movably connected with a base, and a lifting hydraulic rod is arranged between the frame body and the base and used for driving the lifting support arm to expand or contract so as to achieve lifting of the bearing table. Further, the side limiting parts are arranged on the frame body and used for limiting the unfolding angle of the lifting support arm and preventing the lifting support arm from being excessively unfolded. Further, the lifting support arm is movably connected with the frame body through a rotary connecting shaft, and an antifriction structure is arranged on the periphery of the rotary connecting shaft and used for reducing friction force when the lifting support arm rotates. Further, a spring installation roller is arranged on the base, one end of the spring installation roller is provided with a support arm connecting block, a buffer spring is arranged in the spring installation roller, and the buffer spring is used for buffering impact force between the lifting support arm and the base.
