Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of iron tower foot welding, and particularly relates to an iron tower foot welding device facilitating support adjustment. BACKGROUND

[0002] In the manufacturing process of an iron tower, the iron tower foot is generally a prefabricated part. When the iron tower is installed on site, the tower foot is only needed to be installed on the pre-dug concrete pit foundation, and then the tower body column is welded with the connecting plate of the tower foot to complete the installation of the iron tower. Therefore, the welding quality of the tower foot is crucial. The tower foot is composed of a tower foot bottom plate and a connecting plate. The tower foot bottom plate is a key component for connecting the tower foot with the concrete pit foundation and plays a role in transmitting the load of the tower foot to the pit foundation. The tower foot bottom plate is generally a square steel plate with a thickness determined according to design requirements. The support steel plate is used for welding with the tower body column during installation. The support steel plate is generally cross-shaped and is fixed on the tower foot bottom plate by welding in advance. The uniformity and strength of the weld need to be ensured during welding. The conventional welding device often has difficulty in achieving quick and accurate support adjustment due to the size difference between the tower foot bottom plate and the support steel plate, resulting in low welding efficiency and unstable welding quality. In addition, the tower foot needs to be kept at a precise position and angle during welding to ensure the quality of the welded joint. If the support device cannot be adjusted flexibly, the tower foot bottom plate and the support steel plate may be displaced or deformed during welding, resulting in a welded joint that does not meet the design requirements.

[0003] The Chinese patent document with publication number CN119457661A proposes a tower foot welding positioning device for a power transmission and transformation iron tower. Two fixed assemblies are symmetrically arranged on the processing table. The fixed assembly includes two bottom seats and a first sliding groove arranged symmetrically left and right. The support steel plate is placed between the two bottom seats. The lower end of the bottom seat is provided with a first sliding block in sliding cooperation with the first sliding groove. The support plate is pushed to make the support plate drive the clamping plate to slide, so that the clamping plate drives the reinforcing steel plate to move on both sides of the support plate, and then the bottom end of the limiting rod contacts the processing table. Through the friction force between the limiting rod and the processing table, the bottom plate can be limited, so that the position of the support plate and the clamping plate is fixed, and the position of the reinforcing steel plate can be adjusted conveniently. However, in the above-mentioned manner, the clamping plate relies on the friction force between the bottom of the limiting rod and the processing table to fix the position. During welding, the welding operation of the welding gun may be hindered, and displacement may occur due to the bumping and vibration of the welding gun or other components, thereby affecting the welding quality.

[0004] Therefore, the iron tower tower foot welding device convenient to adjust the support is provided, the problem that the clamping plate clamps the support plate, and the welding gun welding operation is hindered, and the welding quality is affected due to the knocking and vibration of the welding gun or other components in the welding process is solved, the tower foot support structure is improved, the multidirectional adjustable support limiting structure is designed, and the welding limiting frame is matched, the welding area is limited, and the welding process is uniform and stable.
