Description

Technical Field

[0001] The present invention relates to the technical field of pipeline auxiliary welding, and particularly to a large-scale HVAC pipeline auxiliary welding device at the construction site. Background Art

[0002] In the field of building construction, the HVAC project, as an important component, undertakes the task of ensuring the operation of ventilation, air conditioning and other systems within the building. Among them, the installation quality of HVAC pipelines is directly related to the performance and stability of the entire HVAC system. And during the installation process of HVAC pipelines, welding operation is a key link to ensure firm connection and good sealing of the pipelines.

[0003] With the acceleration of the urbanization process and the continuous expansion of the building scale, the application of large-scale HVAC pipelines is becoming increasingly widespread. These large-scale HVAC pipelines usually have the characteristics of large diameter, thick wall and long length, and their welding construction is more difficult. At the traditional construction site, the welding of large-scale HVAC pipelines mainly relies on manual operation of auxiliary tools to complete, and this method has many limitations.

This precise horizontal maintenance function is crucial for ensuring welding quality because the levelness of the pipeline directly affects the quality and tightness of the welded joint. At the same time, the precise control capabilities of the translation mechanism and the horizontal driving component make the movement of the first pipeline during the welding process smoother and more accurate, further improving the welding precision and quality.

[0020] The unique design of the docking auxiliary welding mechanism enables it to adapt to HVAC pipelines of different shapes and pipe diameters. The mutual cooperation of components such as the docking semi-circular frame, rotating base, and rotating arc frame in the first docking welding component and the second docking welding component can provide stable support and guidance for the docking of the two pipelines. During the welding process, these components can ensure that the relative position between the pipelines remains unchanged, and at the same time, they can adapt to the small deformations caused by factors such as thermal expansion of the pipelines during welding, ensuring the quality and tightness of the welded joint. This versatility and adaptability enable the device to play a good role in various different construction sites and working conditions. BRIEF DESCRIPTION OF THE DRAWINGS
