Description

Technical Field

[0001] The utility model belongs to the technical field related to portal welding machines, and specifically relates to an anti-displacement device added to a portal welding machine. Background Art

[0002] The H-shaped steel is an economic section high-efficiency profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio, and it gets its name because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost savings, and light structural weight in all directions. The H-shaped steel can be produced by two methods: welding or rolling. The welded H-shaped steel is to cut the strip steel with a suitable thickness into a suitable width and weld the flange and web together on a continuous welding machine set. The portal welding machine is a special welding device for welding the fillet welds of H-shaped steel, and is provided with traveling wheels to cooperate with the H-shaped steel for positioning, and has good orientation and positioning effects (as shown in the appendix Figure 6 ), due to the limitations of the positioning device and the positioning method, the processing range of the portal welding machine is limited, and it cannot meet the welding processing use requirements of welded box girders.

[0003] In view of this, the present utility model is specifically proposed. Content of the Utility Model
