AI Technical Summary

Technical Problem

The installation of offshore wind turbines is difficult, and traditional methods require large cranes and wind power installation platforms, which leads to expensive and greatly affected by the natural environment, so it is impossible to lift parts by just a transport ship.

Method used

A fan tower crane equipment is designed, including a cylindrical climbing device and a lifting head. The tower is alternately climbed and fixed through the embracing structure and driving components of the upper and lower climbing barrels. The lifting head is used to hoist the blades and the unit, and only a transport ship is required. Carry out transportation and installation.

Benefits of technology

The volume and cost of lifting equipment is reduced, the stability and wind resistance are improved, and the ability to operate stably under the influence of offshore wind and waves is realized, and the possibility of transporting and installing parts is achieved using only the transport ship.

Abstract

The present invention discloses a wind turbine tower crane device and an installation method. The wind turbine tower crane device includes a climbing device and a lifting head. The climbing device is set as a cylindrical structure, and there is a space for accommodating a wind turbine tower. The lifting head is installed on the top of the climbing device, and the lifting head is used to lift the wind turbine blades. The climbing device includes an upper climbing tube and a lower climbing tube. The lower climbing tube is set with an upper opening. The upper climbing tube is slidably plugged into the upper end of the lower climbing tube, and the upper climbing tube and the lower climbing tube are connected by a driving assembly. The inner wall of the upper climbing tube is installed with a first clamping assembly, and the inner wall of the lower climbing tube is installed with a second clamping assembly. The first clamping assembly and the second clamping assembly are both used to clamp the wind turbine tower. The present invention has the advantages of relying on the wind turbine tower for climbing, lifting and assembling the parts of the wind turbine, and greatly reducing the volume and cost of the traditional crane, and can be transported only by a transport ship.
