Description

Technical Field

[0001] The utility model relates to the field of crawler cranes, in particular to welding equipment for processing swing legs of crawler cranes. Background Art

[0002] Crawler crane refers to a multi-action lifting machinery that can lift and carry heavy objects vertically and horizontally within a certain range. Cranes are made of metal. In the production process of cranes, the welding quality of components is particularly important. According to the patent office database search, the publication number CN208592517U is a welding device for crane parts processing. By setting a first rotating shaft and a second rotating shaft, the nozzle equipment is driven to move up and down, and then the rotating table in the disc can make the nozzle equipment turn 360 degrees. The rotating block set at the right end of the upper top seat can make the equipment move greatly. The combination can better move the position of the equipment, which is convenient for users. Due to the large size of the crawler crane swing leg, after the crawler crane swing leg is placed on the placement table, the welding range of the welding equipment is limited, and the crawler crane swing leg cannot be welded in a wider range as a whole. In addition, during the welding process, the smoke generated by welding directly floats into the factory building, continuously polluting the air in the factory building.

[0003] Therefore, it is necessary to invent a welding device for crawler crane swing leg processing. Utility Model Content
