Problems solved by technology

[0004] However, in the process of hoisting the nose split single blade, since the hub is transported upright to the machine position, it is necessary to turn the hub 90° on the deck of the installation ship and dock it with the generator in the air during hoisting. Usually two cranes are required to cooperate, and because the installation process lasts for a long time, the resources of the crane are occupied

Embodiment Construction

[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, it should not be understood that the embodiments of the present disclosure are limited to the embodiments set forth herein. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0039] When the hub is transported to the machine site through the transport tool, the state is that it is standing on the transport tool, that is, the flange of the hub 38 connected to the generator of the wind turbine is placed horizontally facing downwards. The state is called the vertical state. When the flange surface of the hub 38 connected to the generator of the wind turbine is a vertical state after the hub 38 is installed in the air, the present disclosure refers to this state of the hub 38 as a horizontal state.

[0040] refer to figure 1 , the present disclosure provides a spreader that can b...

Abstract

The invention provides a lifting appliance which is used for lifting a hub of a wind generating set. The upper end of the longitudinal beam is connected to the cross beam; the pivot shaft extends approximately parallel to the cross beam and is rotatably supported at the lower end of the longitudinal beam; the rotating module comprises a connecting disc used for being connected with a part to be lifted, and the connecting disc is connected to the first end of the pivotal shaft; the lifting appliance comprises a pivot shaft and a rotating module which is connected to the pivot shaft and can rotate along with the pivot shaft, the rotating module can be connected with a part to be lifted, and the driving assembly is connected to the pivot shaft so as to drive the connecting disc to rotate by driving the pivot shaft to rotate. And the pivotal shaft rotates to drive the to-be-hoisted component to rotate and even overturn, so that the difficulty of the hoisting process is reduced, and the mounting efficiency is improved.

Description

technical field [0001] The present disclosure belongs to the technical field of construction machinery, and in particular relates to a hub hanger for hoisting a wind turbine. Background technique [0002] At present, one of the more mainstream installation methods of offshore wind turbines is single-blade hoisting. The whole machine head is hoisted by a single blade, that is, the nacelle, generator, and hub are assembled in the factory as a whole, and then the three components are hoisted as a whole when they arrive at the offshore location, and finally each blade is installed independently; The single-blade hoisting of the nose is split, that is, the nacelle, generator, and hub are not pre-assembled in the factory. The three components are separated from the factory, and then hoisted separately at the offshore location. Finally, each blade is installed independently. . [0003] The installation method of the single-blade hoisting with the split head of the machine head ha...
