Description

Blade root support module and blade support tool

Technical Field

The invention belongs to the technical field of wind power generation, and particularly relates to a blade root support module and a blade support tool.

Background

At present, the offshore wind generating set with the smaller impeller diameter still adopts the three-blade type hoisting in China, and the tooling development cost required by the single-blade type hoisting is higher than that of the three-blade type hoisting.

When the three-blade type hoisting is adopted, in the transportation process, the blade is installed on the blade transportation tool in a horizontal posture, and the blade root and the blade tip are respectively provided with one transportation tool, so that two-point transportation is carried out. The blade root transport tooling is generally a simple bracket connected to the blade root flange by bolts. The blade tip transportation tool comprises an upper cover plate, a middle bottom support and a lower support, wherein the upper cover plate presses the upper surface of a blade, the middle bottom support supports the lower surface of the blade, the upper cover plate and the middle bottom support are connected into a whole through a bolt, and finally the whole blade tip transportation tool is supported on the lower support.

In the impeller assembling process, the hub is pre-arranged at a fixed position of an installation ship, and the double-hook lifting blades of the installation ship are required to be assembled and butted with the impeller variable pitch bearing. Specifically, the double hooks lift the blades from the blade transport ship, the blade root is in a mode of directly wrapping the blade root through the flat hanging strips, the blade root transport tool is not detached at first, the blade tip part is a hanging ring which hangs the two sides of the middle bottom support through the hanging strips, and the upper cover plate of the blade tip transport tool needs to be detached in advance. The upper cover plate needs to be removed in advance because when the blades are in butt joint with the variable pitch bearings and the lifting straps and the tools begin to be removed, the main crane of the installation ship withdraws the blade root lifting straps, the auxiliary crane of the installation ship withdraws the middle bottom support of the blade tip transportation tool, no other crane resources remove the upper cover plate of the blade tip transportation tool, the upper cover plate and the middle bottom support are connected through bolts, and at the moment, people are required to climb from the surfaces of the blades in a special mode to remove the upper cover plate, and the upper cover plate of the blade tips is exposed out of a ship deck, so that the risk is.

In addition, when the blade is transported to the mounting ship, before the blade root transportation tool and the bolt connected with the blade root flange need to be detached, then the stud of the blade root flange is mounted, the diameter of the pitch circle of the blade root bolt is measured, if the blade root bolt deforms, correction needs to be carried out, and after all the bolts are prepared, butt joint work of the blade and the blade root flange is carried out, so that the whole process is long in time consumption and low in efficiency.

Known, the transportation frock and the impeller of present blade are assembled and are had following problem:

first, the blade root transportation frock passes through tool bolt and blade root flange joint, before assembling the impeller, need demolish tool bolt from the blade root flange, then installation blade root flange stud, whole dismantlement and installation process length consuming time, and is inefficient, if meet bolt card die or bolt thread damage, the time of dismantling can be longer.

And secondly, the blade root transportation tool is connected with the blade root flange through the tool bolt, when the blade is transported to the installation ship from the transportation ship, the risk of blade root bolt reference circle deformation is generated no matter the blade root transportation tool is hung by a hanging strip or the blade root part is covered by a flat hanging strip, and the blade root transportation tool has no deformation resistance.

Thirdly, before the blades are transported from the transport ship to the installation ship, the blade tip upper cover plate needs to be detached, and once the blades are butted, the upper cover plate cannot be detached. However, after the upper cover plate is removed, the structural strength of the blade tip becomes poor, and when the blade is transported backwards, the blade easily slides off the blade tip transportation support, so that certain potential safety hazards exist.
