Method for supporting tower outer ladder of wind generating set and adjustable supporting device

Abstract

The invention relates to a method for supporting tower outer ladder of wind generating set and an adjustable supporting device. A fixed stairway and the adjustable supporter are combined to form a floating supporter, and by utilizing the adjustability of the floating supporter, and according to the different conditions of foundation of an external wind power generating set stairway, the method adjusts the floating supporter, so that the floating supporter can be steadily supported on the foundation of the external wind power generating set stairway. The floating supporter is a bi-directionally adjustable supporter which is connected to the end part of a vertical external wind power generating set stairway plate, and can be rotated and extended, the rotatable part of the adjustable supporter can be directly rotated to be adapted to a different foundation-extended face, the extendable part of the adjustable supporter can be adjusted to adjust the height of the whole stairway when the foundation height is ununiform, and the bi-directional adjustment mode for angle and height ensures that different foundations and stairways can be in reasonable and safe contact.

Description

technical field [0001] The invention relates to an installation method and structure of components of a wind power generating set, in particular to a method and a supporting device for a ladder outside a tower of a wind power generating set, which are mainly used in a wind generating set. Background technique [0002] In recent years, with the rapid growth of my country's economy, the contradiction of national power supply shortage has become more and more prominent. In addition to thermal power and hydropower, wind power is the most mature renewable energy development and utilization and has the most commercial development prospects, so it has been awarded High-speed development. Moreover, with the continuous increase of the power of wind turbines and the emergence of new models with different environments and loads, various towers and foundations have been produced accordingly. Since the design unit of the wind turbine tower and tower outer ladder is the main engine factor...

AI Technical Summary

Problems solved by technology

[0003] 1. For different unit environments, OEMs need to design tower external ladders with different heights and angles, and the drawings lack versatility;

[0004] 2. In the actual construction, the technical communication between the four parties is not in place or the normal construction deviation will lead to the inconsistency between the feet of the ladder outside the tower and the backfill surface of the foundation. Cut the ladder support plate outside the tower; when the expansion surface of the foundation is low or the amount of backfilling soil and rocks is not enough, the ladder will not fall to the ground, and the bottom needs to be filled with cement blocks, bricks and sandbags, etc.

[0005] These two defects both affect the appearance and have safety hazards, so it needs to be improved
