Description

Technical Field

[0001] The utility model belongs to the technical field of fixing devices, and in particular relates to a fixing device used for vertical transportation of an offshore wind power tower. Background Art

[0002] With the vigorous development of offshore wind power, more and more transport ships are used to transport wind turbine components, among which the most common wind turbine components are towers (also called tower barrels). There are a large number of wind turbine towers, and it is troublesome to fix them on the ship during transportation. Therefore, the transportation of towers requires a large amount of transport tooling to fix them. Common tower tooling includes horizontal transport tooling and vertical transport tooling. The horizontal transport tooling adopts a steel meniscus model, and the bottom is welded and fixed to the deck surface. Each section of the tower requires two or more sections of horizontal transport tooling to support and place it. The horizontal transport tooling is at high risk of being affected by surges, occupies a large amount of deck space, and the tower is placed flat on the horizontal transport tooling. Before fixing, the tower needs to be turned over to be fixed. The on-site loading and unloading work is extremely inconvenient, the loading and unloading efficiency is not high, and it is easy to increase the transportation cost; while with the traditional vertical transport tooling, the tower does not need to be laid flat to be placed vertically It is fixed on a vertical transport tooling, and the structure is usually relatively fixed. One vertical transport tooling can only meet the fixed transportation of one tower. When faced with towers of different specifications, it is difficult to use it again, lacking transportation flexibility. When the project is large and there are a large number of wind turbines to be installed, it is necessary to purchase a large number of vertical transport tooling of different specifications. After one use, most of them will be idle, which is easy to cause a waste of resources. It can be seen that there is currently a lack of a fixing device for vertical transportation of offshore wind power towers, which can adapt to the transportation of various types of towers while reducing the use of deck space, improve the flexibility of tower shipping and transportation, reduce the waste of vertical transport tooling resources, and save transportation costs.
