Description

Technical Field

[0001] The invention relates to the technical field of welding turnover tooling, in particular to a position turnover tooling for welding of steel components of an iron tower. Background Art

[0002] Steel tower components refer to various steel components used in the structure of steel towers, which are widely used in the fields of communications, power transmission, broadcasting, etc. The design and manufacture of steel towers usually require high strength, corrosion resistance and good stability to ensure their safety and reliability under different environmental conditions.

[0003] Types of steel components of the tower: Main beam: The main load-bearing component of the tower, responsible for supporting the weight of the entire structure. Diagonal brace: Used to enhance the stability of the tower and prevent lateral swing or tilt. Column: Vertical component, supporting the overall structure of the tower and bearing vertical load. Crossbeam: Connects the columns to enhance the rigidity and strength of the tower. Base: Fixes the tower to the ground, distributes the load, and provides a stable foundation.

[0004] Welding is an important part of steel component processing, especially in the manufacturing process of iron tower structures. Reasonable welding position is crucial to welding quality and efficiency. In order to improve welding efficiency and ensure welding quality, position flipping tooling can be used. Position flipping tooling is a device used to support and flip iron tower steel components, with the purpose of adjusting the workpiece to the best welding position.

[0005] The document with prior art publication number CN117817251A provides a position flipping tool for welding steel components of an iron tower, which can facilitate the placement and removal of heavy workpieces. The operation is simple and convenient, which reduces the burden of lifting for workers and avoids injuries caused by falling. It has high safety and can also have dust collection and purification functions to promptly deal with harmful gases floating below, thereby ensuring the health of workers and having high practicality.

[0006] The existing technology fixes the workpiece by means of a pressure plate, but the pressure plate is only suitable for clamping and fixing planar workpieces. For the triangular iron in the steel structure of the iron tower, the traditional pressure plate clamping technology has significant defects in clamping stability, positioning accuracy, processing flexibility and safety.

At the same time, the component seat located under the workpiece can receive the workpiece when it falls, so as to prevent it from falling and injuring the workers. At the same time, by setting up a transmission mechanism and a pushing rack, the welded workpiece can be automatically pushed to the subsequent processing or storage area, thereby improving production efficiency. The automated design reduces the labor intensity of workers, avoids heavy manual handling, and improves the overall working comfort. BRIEF DESCRIPTION OF THE DRAWINGS
