Abstract

The invention provides an impeller assembling tool for an offshore wind generating set and an impeller assembling method. The impeller assembling tool comprises a hub mounting part, a rotary supporting table and multiple supporting rods, wherein the hub mounting part is used for fixedly supporting a hub; the rotary supporting table is located below the hub mounting part and rotationally mounted ona mounting platform; and the upper ends of the multiple supporting rods are connected to the hub mounting part, the lower ends of the multiple supporting rods are connected to the rotary supporting table, and the multiple supporting rods can stretch and retract, so that the position of the hub mounting part can be adjusted. According to the impeller assembling tool for the offshore wind generating set, in the process of assembling blades and the hub, butt joint of the hub and the blades is realized in the mode that the hub moves while the blades do not move, and therefore, compared with the mode that a crane is used for hanging the blades for mounting in the prior art, the problem that the blades are difficult to mount due to shaking of the crane is avoided.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an impeller assembling tool for an offshore wind power generating set and an impeller assembling method for an offshore wind generating set. Background technique [0002] Currently, offshore wind turbine impellers are assembled on jack-up installation vessels. For this purpose, usually two stationary cranes (ie main and auxiliary cranes) or one main crane and one crawler crane are arranged on board the installation vessel. Assemble the impeller by using two cranes to hang on the blade root lifting point and the blade tip lifting point respectively to install the blade on the hub. [0003] In recent years, as the length of the blades of offshore units has become longer (close to 90m), the distance between the blade root lifting point and the blade tip lifting point has also become longer and longer. Using two fixed cranes on the installation ship to lift the blade w...
