Description
Technical field
The invention belongs to marine transportation manufacturing field, and in particular to a kind of wind-powered electricity generation steel-pipe pile hoisting transportation technique.
Background technology
The project of operation on the sea is bulky, and center of gravity is high, general using manufacture, fragmented transport, segmentation installation is segmented, finally
The method of wind power plant general assembly at sea completes the installation of operation on the sea.Because offshore wind generating is typically using segmentation fortune
It is defeated, during shipping, in order to make full use of limited floor space to transport more steel-pipe piles and Accessory Members and subtract
The deformation of few pylon and steel-pipe pile, transport and the colligation of wind-driven generator steel-pipe pile and ship board are wind-driven generator steel
Pile tube most important link during sea-freight.
Now most steel-pipe pile in transport by the way of uprightly transporting, i.e., it is steel-pipe pile is upright above deck, due to steel
The stake of pile tube is long, and the mode uprightly transported increases steel-pipe pile and ship board transport and the difficulty of colligation, steel-pipe pile
During axial transport, easily appearance lifting is unstable in hoisting process, wire cable rupture, has a strong impact on Hoisting Security, is lifting
During colligation, because misoperation is easy to damage steel-pipe pile surface, some colligations are insecure, easily in transportation
Loosen, influence the normally travel of cargo ship.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to now provide a kind of lifting is steady, avoid wire cable rupture,
