Description

Mounting device, mounting method for reinforcing plate of door opening of tower drum and tower drum of wind generating set

Technical Field

The application relates to the field of auxiliary equipment of wind generating sets, in particular to a mounting device, a mounting method of a tower drum door opening reinforcing plate and a tower drum of a wind generating set.

Background

With the development of the wind power generation industry, megawatt wind generating sets become the mainstream development trend of current wind power generation equipment. As shown in fig. 1, the wind turbine generator system is mainly composed of a tower 20, a nacelle 30, a hub 40, a generator 50, blades 60, and so on. The tower typically requires some tower door openings 70, for example, the lower tower sections require door openings for operator access. To facilitate operator access to the tower door opening 70, the tower is also typically provided with an outside tower access ladder 10. The structural strength of the tower is compromised by the presence of the door opening, often requiring reinforcement. The conventional reinforcement at the tower door opening 70 adopts a ring-shaped reinforced door frame, and the structure of the reinforced door frame is shown in fig. 2. In order to solve the problems of large stress concentration and low allowable fatigue stress amplitude at the welding seam caused by welding the annular reinforced door frame and the tower drum door opening 70, steel plates with larger thickness are used at the annular reinforced door frame and the drum sections at the tower drum door opening 70, so that the weight of the tower drum is greatly increased.

The reinforcing plate is used at the tower barrel door opening 70 to replace the traditional annular reinforcing door frame, and under the same load working condition, the relatively thin barrel plate is used, so that the barrel and the reinforcing plate at the door opening can meet the requirements in the aspects of strength, rigidity, fatigue strength of door frame welding seams and the like, and the weight of the tower barrel is greatly reduced.

However, because the novel tower door opening reinforcing plate structure of the wind generating set has great difficulty in manufacturing, installing and welding processes, in order to ensure the welding precision, the tower door opening reinforcing plate and the tower are required to be accurately pre-positioned at first. However, tower section of thick bamboo door opening reinforcing plate often has characteristics bulky, that weight is big to the tower section of thick bamboo of different models, the mounted position of door opening reinforcing plate is also different, and these factors all can lead to tower section of thick bamboo door opening reinforcing plate and tower section of thick bamboo accurate prepositioning comparatively difficult, influence the installation of tower section of thick bamboo door opening reinforcing plate, and then also can influence the reliability of a tower section of thick bamboo.
