Abstract

The invention discloses a leveling device for a foundation ring of a wind power generation set. The leveling device comprises a plurality of connecting members evenly fastened to the foundation ring of the wind power generation set in the outer circumferential direction. Cushion blocks are arranged on the connecting members and foundation concrete. Fasteners are vertically arranged on the foundation concrete. Panel components are placed on the cushion blocks. The panel components are fixedly connected with the fasteners. The invention further discloses a leveling method using the leveling device accordingly. Before the foundation restoration of the wind power generation set, the multiple connecting members are evenly arranged on the foundation ring in the outer circumferential direction; the multiple fasteners are arranged on the foundation concrete of the outer side of the foundation ring, cushion blocks are placed on the connecting members and the foundation concrete, the panel components are placed on the cushion blocks, and the panel components are fixedly connected with the fasteners; the fastening degree between the panel components and the corresponding fasteners is adjusted until the levelness requirement for the foundation ring is met. The leveling device and method for the foundation ring of the wind power generation set have the advantages of being stable, reliable, rapid leveling and the like.

Description

technical field [0001] The invention mainly relates to the technical field of wind power generation, in particular to a foundation ring leveling device and method for a wind power generating set. Background technique [0002] At present, large-megawatt wind turbines are towering structures, and the external load is mainly wind load. When it is transmitted to the foundation, the main load is moment. The foundation load of 2MW wind turbines usually reaches 70,000kNm. The design of the foundation ring foundation is usually not easy to compact the foundation concrete during construction, resulting in cracking, damage and other damages to the foundation concrete under the action of this large moment, resulting in excessive levelness of the foundation ring. The total weight of the nacelle and the wind rotor of the 2MW wind turbine exceeds 140t. When the level of the foundation is out of tolerance, the change of the center of mass position of the nacelle and the wind rotor will gen...
