A MOVING STRUCTURE OF A WELDING DEVICE

摘要

The present invention relates to a transferring structure for a welding device comprising: a welding device for welding; a rail installed in a member to be welded for guiding the welding device to be transferred; and a driving part equipped in the lower part of the welding device for transferring the welding device by being rotated while being engaged with the rail. The driving part comprises: an upper roller which is rotated by being in contact with the upper surface of the rail; a side roller which is rotated by being in contact with the side surface of the rail; and a lower roller which is rotated by being in contact with the lower surface of the rail. According to the present invention, a transferring structure for a welding device is provided to transfer the welding device along the rail by using a roller which is rotated along the upper, lower, and side surfaces of the rail. Therefore, the welding device can improve the efficiency of welding work since the welding device performs welding while not being separated from the rail and being smoothly moved in vertical welding.
