Annular welding device for wind power tower drum and use method thereof

Abstract

The invention discloses an annular welding device for a wind power tower drum and a use method thereof, and particularly relates to the technical field of wind power tower drums. The annular welding device comprises a reinforcing shell; two retainers are fixedly connected to the upper surface of the reinforcing shell; two bearings are clamped to the upper surfaces of the two retainers, respectively; the same connecting shaft is sleeved into the two bearings; the outer surface of the connecting shaft is fixedly connected with a mounting sleeve; and the outer surface of the mounting sleeve is fixedly connected with the front surface of a welding frame. According to the annular welding device, a magnetic sheet crawler belt, a driving wheel and the reinforcing shell are arranged, so that when the annular welding device is used for welding a wind power tower drum assembly through a welding device, the welding effect is not prone to being influenced by external wind power and gravity factors, and the influence on the welding effect due to dislocation of welding parts is reduced; and the worker can conveniently adjust the position of the annular welding device, so that the dangerousness when the worker climbs up and down the wind power tower drum assembly is reduced, and the safety of the worker is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wind power towers, and more specifically, the invention relates to a ring welding device for wind power towers and a method for using the same. Background technique [0002] With the development of the global economy, the consumption of natural resources continues to increase, and the massive exploitation and use of non-renewable energy such as coal, oil, and natural gas not only creates a huge pressure on the continuous supply of energy, but also brings about greenhouse effects, acid rain, smog, etc. Environmental issues. Wind power has the advantages of clean and non-polluting, large unit capacity, and good economic benefits. In recent years, it has attracted widespread attention from all over the world. It is currently one of the most promising new energy sources. [0003] In order to improve the competitiveness of wind power generation, when installing wind power towers, the pre-supporting rings are ...

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a ring welding device for a wind power tower and its use method. The technical problem to be solved by the invention is: in order to improve the competitiveness of wind power generation, when installing the wind power tower , the pre-supporting rings are often superimposed and placed horizontally so that the welding part forms a ring and then welds it. However, this welding method requires a lot of manpower, and the welding method is single. When it is interfered by external factors such as gravity, it is not only easy to The misalignment of the welding part will affect the welding effect, and the welding of different parts of the wind power tower will easily lead to a greater risk of welding, and it is difficult to ensure the safety of welding personnel
