[0018] Next, with reference to examples, the substantial features and advantages of the present utility model will be further described, but the present utility model is not limited to the listed embodiments.

[0019] Such as Figures 1 to 5As shown in the figure, a rotary hoisting device for shipbuilding in this embodiment includes a traction device 1 and a bracket 2. The traction device 1 is arranged on the bracket 2, and ship components can be hoisted through the traction device 1. The traction device 1 can adopt existing devices such as an electric drum and a winch. The bracket 2 includes a base 21, a mounting frame 22, a telescopic rod 23, a hanging plate 24 and a pulley 25. The mounting frame 22 is arranged on the base 21. The telescopic rod 23 is arranged in the mounting frame 22 and slides relative to the mounting frame 22, so that the extended length of the telescopic rod 23 can be adjusted. The telescopic rod 23 is provided with a limit hole 231, and the mounting frame 22 is provided with a limit member 221 corresponding to the limit hole 231. After the position of the telescopic rod is adjusted, the limit member 221 is inserted into the limit hole 231 for positioning. The limit member 221 can adopt a positioning pin. The pulley 25 is arranged at the end of the telescopic rod 23, and a hanging part 231 is arranged below the telescopic rod 23. The traction device 1 is provided with a mating part 11. The mating part 11 corresponds to the hanging part 231 and is detachably connected through a locking assembly 3, which facilitates the assembly and disassembly of the traction device 1. The hanging plate 24 is arranged on the mounting frame 22. The traction device 1 is arranged on the hanging plate 24 or the telescopic rod 23, so that the traction device 1 can directly hoist components or use the rope on the traction device 1 to bypass the pulley 25. The base 21 includes a clamping groove 211 and an adjusting member 212. The adjusting member 212 is arranged on the side of the clamping groove 211. The hoisting device can be clamped on the fixing part 10 through the clamping groove 211 and locked by the adjusting member 212.
