Description

Technical Field

[0001] This utility model relates to the field of bridge welding technology, specifically a bridge welding device. Background Technology

[0002] Bridges generally refer to structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, bridge materials have gradually changed with advancements in materials technology. Currently, the main structure of bridges is a steel frame combined with a concrete structure. However, existing methods for welding two sets of welded components involve aligning the two sets of welded parts and then welding them together using a welding device. This welding device is prone to causing the two sets of welded parts to separate and become unstable during the welding process, thus affecting the welding effect and resulting in poor practicality.

[0003] For example, CN202022525213.X discloses "A Welding Device for Bridge Construction". It uses two sets of first cylinders to drive two sets of first push rods to move two sets of clamping plates inward to clamp two sets of welded parts and align the welding positions of the two sets of welded parts. The welding positions of the two sets of welded parts correspond to the position of the welding device. Then, the welding device welds the two sets of welded parts, thereby avoiding the loosening of the two sets of welded parts during the welding process, thus improving the welding effect of the two sets of welded parts and improving its practicality.

[0004] The above-mentioned method uses a cylinder and push rod to clamp and fix the bridge steel with a clamping plate. However, the cylinder is in a fixed state. When welding bridge steel of different lengths, the clamping angle of the cylinder, push rod and stiffening plate is fixed, which is not conducive to the welding process of the bridge steel.
