Description

Technical Field

[0001] The present application relates to the field of wind power equipment transportation, and in particular, to a wind power tower transportation device and transportation method. Background Art

[0002] The demand for green energy in various countries has driven the export demand for wind power equipment. As the main component of wind power equipment, wind turbine towers are usually large in size. How to safely and economically transport wind turbine towers during ocean transportation has become a problem that needs to be solved.

[0003] The ocean-going transportation of wind turbine towers usually adopts the method of laying the towers flat on the deck of the ship. This is because the height of wind turbine towers is relatively high, and the towers are difficult to carry vertically on and off the ship, and difficult to fix vertically on the deck of the ship. The vertical tower transportation system of the prior art is usually only suitable for short-distance transportation and can only transport a single or a small number of towers each time. It is not suitable for the large-scale ocean transportation of towers required for the export of wind power equipment. The disadvantages of the existing flat tower transportation system are low transportation efficiency, and laying the tower flat during long-distance transportation can easily cause the tower cross-section ovality to exceed the standard. At the same time, the transportation base is prone to fatigue damage, which greatly increases the economic cost and carbon emissions of tower transportation, which does not conform to the core value of the green economy.
