Description

Joint welding device for steel pipe pole Technical Field The invention relates to the technical field of welding equipment, in particular to a joint welding device for a steel pipe rod. Background The steel pipe pole is used as a main bearing member in the modern power, communication and illumination tower pole structure, and is widely applied to scenes such as high-voltage and ultra-high voltage transmission line towers, communication signal towers, urban road illumination lamp poles, wind power generation equipment supporting towers and the like due to the advantages of high structural strength, good wind resistance, attractive appearance, convenience in mechanical processing and the like. The processing process of the steel pipe rod mainly comprises the following steps of firstly, accurately rolling a steel plate with a specific specification into a cylindrical steel pipe through plate rolling equipment, forming a longitudinal joint on the side wall of the steel pipe, then accurately aligning and fixing the steel plates on two sides of the joint by using joint equipment, and finally, finishing firm connection of the joint through an automatic or semi-automatic welding process, thereby forming the steel pipe rod piece with complete structure and reliable performance. However, during the rolling and subsequent seaming of the steel pipe pole, a problem of "misalignment" sometimes occurs. The method is characterized in that when the steel plate is rolled into a cylindrical steel pipe, the edges of the steel plates at two sides of the joint are not perfectly aligned in a flush manner, but form dislocation along the length direction of the joint. If the problem of the misalignment is not controlled, the subsequent welding quality can be directly affected, so that poor weld formation and stress concentration are caused, and the overall structural strength and fatigue performance of the steel pipe pole are further weakened. Therefore, the method is prevented and controlled by optimizing the plate rolling process, precisely adjusting the joint closing equipment and checking the reinforcing process in the machining process. When facing such a problem of misalignment, the existing joint sealing device often lacks an effective online correction mechanism, resulting in reduced production efficiency or requiring manual secondary correction.
