Technical Field

[0001] The utility model relates to the technical field of steel claw welding equipment, in particular to an online welding equipment for electrolytic aluminum steel claws. Background Art

[0002] In the use of modern electrolytic aluminum steel claws, as the steel claws are consumed as cathodes, the claw teeth of the steel claws need to be removed for welding again. The existing technology is to cut off the old claw teeth that are consumed too much, replace the new claw teeth with the steel claw body for arc welding, and the arc welding method is to use metal electrode gas shielded welding equipment for manual welding.

[0003] At present, there are the following problems when replacing the claw teeth of the electrolytic aluminum steel claw:

[0004] 1. When preparing for welding, the electrolytic aluminum steel claw needs to be hoisted to the ground, and the steel claw body and claw teeth need to be placed before welding. The welding preparation work is complicated and the operation is cumbersome;

[0005] 2. The welding is carried out using metal arc welding equipment. Since the claws of the steel claws have a thicker diameter, the efficiency of this welding method is relatively low. In addition, when performing different steel claw welding operations, the welding equipment needs to follow the movement of the steel claws, which increases the complexity of the equipment.

[0006] 3. The overhead crane needs to perform two tasks: lowering and lifting the steel claw. After welding is completed, the steel claw needs to be lifted back to the side of the electrolytic cell. The operation steps are cumbersome and increase the wear of the overhead crane winch equipment. In view of this, an in-depth study was conducted on the above issues, which led to this case.
