Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of welding assistance, and in particular relates to a full-size pipeline automatic welding system with integrated tracks and docking devices. Background Art
[0002] In modern industrial production, pipeline welding technology plays a vital role, especially in important industries such as oil, natural gas, chemical industry, and electric power. The welding quality of the pipeline system is directly related to the safety, reliability, and economic benefits of the entire project. Traditional pipeline welding methods mainly rely on manual operation, which is not only inefficient, but also prone to quality fluctuations due to human factors, making it difficult to meet the strict requirements of modern industrial production for high efficiency, high quality, and high consistency.
[0003] With the development of automation technology, various automatic welding equipment have appeared on the market, trying to solve the problems of manual welding. However, these equipment still have many limitations and shortcomings in practical applications. First, the scope of application of most automatic welding equipment is relatively narrow, and it is often only used for welding pipes of specific sizes or specific positions, which is difficult to meet the diversified needs of full-size welding in industrial production. Secondly, in the process of pipeline welding, accurate matching is a key factor to ensure welding quality, but existing equipment often has difficulty in achieving high-precision matching, especially on large-diameter pipes, this problem is more prominent. In addition, many existing automatic welding equipment requires a complex track installation process, which not only significantly increases the preparation time, but also increases the difficulty of operation and reduces the overall work efficiency. At the same time, these equipment are usually not flexible enough, and it is difficult to adapt to different welding process parameters and a variety of pipe materials, and cannot meet the increasingly complex industrial production needs. Another common problem is that the equipment is not highly integrated, and the welding equipment, track system and matching device are often separated, which not only increases the complexity of the equipment, but also increases the failure rate and maintenance difficulty.
[0004] Taking all the above factors into consideration, developing a device that can adapt to full-size pipelines, realize automatic welding, and integrate track and high-precision docking functions is of great practical significance and urgent need to improve the efficiency and quality of pipeline welding. This new device can not only greatly improve welding efficiency and reduce human errors, but also ensure the consistency of welding quality, thereby significantly improving the safety and reliability of the overall project. Such an integrated device will also bring many benefits to industrial production. It can reduce interface problems between equipment, reduce system complexity, and improve overall reliability. Through precise control and real-time monitoring, the comprehensive optimization of the welding process can be achieved, which not only improves product quality, but also reduces material waste and reduces production costs. At the same time, the improvement of automation will also greatly improve the working environment of workers, reduce occupational hazards, and improve work safety. Summary of the invention

[0011] Furthermore, one end of the telescopic support leg is inserted into the support base and fixed by bolts, and the other end is connected to the outer wall of the pipe to be welded. By moving the telescopic support leg up and down, the automatic welding track is suitable for welding pipes of full sizes within a set range.
[0012] Furthermore, a long strip keyway is processed on the telescopic support leg; a convex block is arranged on the inner wall of the support base; and the convex block cooperates with the keyway to prevent the telescopic support leg from rotating relative to each other.
[0013] Furthermore, the docking base is provided with evenly distributed docking base holes.
