Description

Technical Field

[0001] This utility model relates to the field of welding head mounting structure, and in particular to a multi-angle adjustable welding head structure for gantry welding equipment. Background Technology

[0002] The gantry beam is the transverse structure of a crane and its load-bearing component. Located between the columns, it supports and suspends the crane's main parts. Typically made of steel plates, the gantry beam possesses high strength and corrosion resistance, enabling it to withstand large loads and shear forces. During production, the gantry beam's components are welded using gantry welding equipment. However, the welding head structure in existing gantry welding equipment is relatively fixed and cannot be adjusted to suit specific welding points. This results in some necessary welding points not being covered, leading to insufficient welding coverage and affecting the welding requirements of the gantry beam, thus failing to meet the company's production needs.
