Description

technical field

[0001] The invention belongs to the technical field of welding equipment, in particular to a three-position adjustable elastic positioning walking device. Background technique

[0002] At present, the automatic welding of pile pipes / pipes mainly adopts gas metal shielded welding or self-shielded flux cored wire welding multi-layer multi-pass welding process, and its welding equipment mainly adopts track joint double-arc plate transition flexible arc welding track + walking welding head It is a pipe automatic welding equipment mode; its working method is that before welding, the welder installs a flexible track parallel to the weld on the top / side of the weld, and then installs the walking welding head on the track, and the head walks along the track. The welder adjusts the welding torch installed on the machine head to track the welding of the weld.

[0003] In the prior art, the angles and positions of the 4 or 5 traveling / driving wheels at the bottom of th...
