[0027] Working principle: The column structure of the power tower is usually the main support component of the tower, which bears the weight of the tower and ensures the stability of the tower. The column is the main vertical support structure of the power tower, usually made of steel pipe material, with strong bearing capacity and wind resistance. In order to enhance the stability of the column, diagonal bracing is usually needed to prevent the tower from tilting laterally. The diagonal bracing is generally connected with the column through welding to transfer and distribute the load. The welding equipment includes a welding fixture for fixing the welding parts to ensure the accuracy and stability during welding. The welding equipment is in an open state, and the slag generated during welding has penetrating power and heat, which may cause workers to be scalded and stabbed, reducing the safety of the welding equipment. The slag on the welding table is not easy to clean, and the noise generated during welding is large. Therefore, it is particularly important to design a welding equipment for the column structure of the power tower. Two protective plates 8 can cover the four sides of the welding seat 1, avoiding the flying of slag during the welding process of the column structure, and accidentally hurting nearby workers. By applying an upward force to the two protective plates 8, the adjusting block 7 is moved upward at one end of the auxiliary rod 6. By moving the protective plate 8, it is convenient to clean the slag and dirt on the surface of the welding seat 1. The observation window 9 is made of transparent glass, which can clearly see the welding situation of the column structure through the observation window 9. The sound-absorbing layer 16 is made of polyester fiber material, which can absorb sound waves in the air, reduce sound reflection and reduce noise propagation. The compression layer 17 is made of polymer material, which mainly bears the external pressure load and maintains the stability of the protective plate 8. When the two protective plates 8 shield the welding seat 1, the one end of the two limiting strips 10 is embedded into the inside of the two first limiting holes 11 in turn, and the two are screw connected, so that the protective plate 8 and the welding seat 1 can be installed. When the protective plate 8 moves upward, the one end of the limiting strip 10 is embedded into the inside of the second limiting hole 12, and the two are screw connected, so that the top plate 13 and the protective plate 8 can be limited and fixed, thereby the position of the protective plate 8 can be adjusted.
