Description

Technical Field

[0001] The invention relates to the technical field of power transmission tower production, in particular to a power transmission line iron tower base welding device. Background Art

[0002] Transmission line towers are referred to as power towers. Their structural characteristics are that all types of towers are space truss structures. The rods are mainly composed of single equilateral angle steel or combined angle steel. The entire tower is composed of angle steel, connecting steel plates and bolts. Individual parts such as tower feet are welded from several steel plates into a combination. Transmission towers are tall steel structures that are very sensitive to tilt, deformation and welding strength. In recent years, with the rapid development of power grids, high-voltage and high-current, large-section conductors and double-circuit transmission towers on the same tower have become more and more common. These heavy towers often use a double-main-material structure; at this stage, the double main materials are often connected in the form of angle steel or cross-welded plates.

[0003] When welding the connection of the tower, the welding angle needs to be adjusted continuously to ensure the stability of the device. The selection of the welding rod angle has a direct impact on the welding quality. If the angle is too large or too small, it may cause unstable molten pool, pores, undercut and other defects. The correct welding rod angle can ensure that the molten pool is heated evenly, avoid the molten metal from dripping or accumulating, thereby improving the quality and aesthetics of the welded joint. In addition, during the welding process, the weld will have a large number of bubbles in the welding rod due to the high temperature of the welding rod during welding and the contact with the active gas in the control, which affects the overall toughness of the device.

[0004] Therefore, it is necessary to provide a transmission line tower base welding device to solve the above problems.
