The invention provides a compact deck folded crane for a ship. The crane comprises a deck hoisting cabin, mounting bases, pin holes, plungers of rotary cylinders I, limiting hinge mechanisms, pins I,first suspension arms, telescopic cylinders I, auxiliary suspension arms I, auxiliary suspension arms II, hinges, a cabin cover, a screw group, fixed bases, rotary cylinders II, hoisting triangular frames, movable hinges, cylinder bodies of telescopic cylinders II, piston rods of the telescopic cylinder II, a rotating beam shaft, a pulley, second suspension arms and an auxiliary cabin cover, wherein during use, the folded crane is unfolded step by step through a hydraulic cylinder control system, the rotary cylinders I drive the two first suspension arms, the two hoisting triangular frames andthe two second suspension arms to rotate by 90 degrees, then the telescopic cylinders I extend to push the hoisting triangular frames and the second suspension arms to enable the first suspension arms to be attached to a deck, the rotary cylinders II drive the hoisting triangular frames and the second suspension arms to rotate to enable the hoisting triangular frames to be attached to the deck, finally, the telescopic cylinders II push the second suspension arms to rotate, and a lifting rope is put down through the pulley. The crane is applicable to recycling machines and transportation machines.
Description
technical field [0001] The invention relates to a marine compact deck folding crane, which belongs to the technical field of marine launching recovery. Background technique [0002] In recent years, with the rapid development of technology and cross-border integration, the exploration and development capabilities of marine resources have also achieved great progress. The 2019 China Ocean Economy Expo showcased new technologies and achievements in the field of marine engineering equipment, and the launching and recycling of these unmanned ships, marine robots and marine detectors are inseparable from marine cranes. At present, most domestic gantry cranes, tower cranes and single-arm folding cranes are used to realize launching and recovery equipment. Although these marine cranes have many advantages, they also have some disadvantages, that is, the cranes are self-heavy, high center of gravity, and large in size. Most of these cranes are installed on the deck, which has a cer...
