Lifting transportation process of wind power steel pipe piles

Abstract

The invention discloses a lifting transportation process of wind power steel pipe piles, comprising: selecting a floating crane, calculating lifting parameters of the floating crane, selecting liftingpoints for steel pipe piles, selecting a transport vessel, selecting transport supports, installing the transport supports, lifting the steel pipe piles, loading the steel pipe piles, tying the steelpipe piles, and installing auxiliary parts. The lifting transportation process of wind power steel pipe piles has the advantages that the process steps are stable and ordered, lifting is table, tyingfirmness is good, two lifting points selected, the position of a hook combiner is determined, the included angle between two lifting wire ropes is not greater than 45 degrees, tension between the lifting wire ropes is decreased, breakage of the lifting wire ropes is avoided, slight increase of one end in weight due to the sliding of the lifting wire ropes to the middle of a steel pipe pile is also prevented, and lifting safety is ensured; by calculating the number of the transport supports and bearing capacity of each transport support, no damage can be caused to the transport vessel during transport of the wind power steel pipe piles; the steel pipe piles are tied firmly and stably, shaking of the transport vessel during transporting is avoided, and transport safety is ensured.

Description

technical field [0001] The invention belongs to the field of marine transportation and manufacturing, and in particular relates to a wind power steel pipe pile hoisting and transportation process. Background technique [0002] Projects for offshore operations are bulky and have a high center of gravity. Generally, they are manufactured in sections, transported in sections, installed in sections, and finally assembled in offshore wind farms to complete the installation of offshore operations. Since offshore wind turbines are generally transported in sections, during the shipping process, in order to make full use of the limited deck area to transport more steel pipe piles and auxiliary components and reduce the deformation of towers and steel pipe piles, wind turbines The transportation and binding of the steel pipe piles and the deck of the transport ship is the most important link in the sea transportation of the wind turbine steel pipe piles. [0003] At present, most ste...

AI Technical Summary

Problems solved by technology

[0003] At present, most steel pipe piles are transported in an upright manner, that is, the steel pipe piles are erected on the deck. Since the pile length of the steel pipe piles is long, the vertical transportation method increases the transportation and binding of the steel pipe piles and the deck of the transport ship. When the steel pipe piles are transported horizontally, the hoisting is likely to be unstable during the hoisting process, and the wire rope is broken, which seriously affects the hoisting safety. During the hoisting and binding, the surface of the steel pipe piles is easy to be damaged due to improper operation. Firm, easy to loosen during transportation, affecting the normal driving of the transport ship
