Abstract

The invention discloses a turnover device used for a main shaft of a wind power generator comprising a support assembly, a turnover stand and a master cylinder. The turnover stand is connected with the support assembly in a rotatable manner and can move to the horizontal level and the vertical level. A support fixing structure used for supporting and fixing the main shaft of the wind power generator is arranged on the turnover stand. One end of the master cylinder is hinged on the support assembly, and the other end of the master cylinder is hinged on the turnover stand. The turnover device has the advantages that the turnover device is simple in structure, low in cost, convenient in operation, stable and safe and high in automatic degree.

Description

technical field [0001] The present invention mainly relates to the field of wind power generation equipment, in particular to a turning device for a main shaft of a wind power generator, especially a turning device for a main shaft of a 2.5 megawatt wind power generator. Background technique [0002] The main shaft of a wind turbine generally has a large size and weight. Taking a 2.5 MW wind turbine as an example, the main shaft of a 2.5 MW wind turbine is 3.3 meters long, with a maximum diameter of 1.6 meters and a weight of 11.5 tons; the assembled main shaft assembly is the largest The diameter is 2.5 meters, the weight is 18 tons, and the length remains the same. Since the main shaft is in a horizontal state during transportation and storage, it is first necessary to turn the main shaft from a horizontal state to a vertical state during assembly to facilitate the assembly of main shaft bearings, bearing housings and other components; after the assembly of the parts on th...
