Description

[0001] Carriage Apparatus for Multi-Position Welding of Longi Partition [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a carriage device for an electron beam welding of a longboard bulkhead in which welding can be performed electronically in a narrow space such as a bulkhead of a ship structure.

Generally, large ships such as oil tankers, drill ships, passenger ships, etc., are equipped with longees on the steel plates to increase the rigidity of the steel plates for constituting the hull.

Drying of the ship is made by welding a large number of steel plates, but welding technology is also important, but the welding must be carried out with the member fixed at a predetermined position. Longi refers to a "T" shaped or "a" shaped member used in shipbuilding, and is welded with a longee standing on the steel plate.

Assembly of objects by welding is still one of the major working methods throughout the industry, but has characteristics that show a large difference in welding quality depending on the skill of the operator.

In addition, many harmful gases are generated during welding, which adversely affects the health of the welding worker. As a result, welding is avoided for the general public. Recently, automatic welding apparatuses have been developed which automatically weld a specific region so as to increase work efficiency and replace labor costs.

For the welding of Longi, Korea Registered Utility Model No. 20-0270489 and Korean Patent Publication No. 2014-0010696 are disclosed for this purpose.

Korean Registered Utility Model No. 20-0270489 discloses a vehicle body having a body on which a driving motor is disposed on a flat top surface of a roof and has a welding soil portion on its left and right sides and a driving wheel is formed on a rear side thereof and a driven wheel is provided on a front side thereof, A lower plate coupled to the lower plate and rotatably coupled to the lower plate and having a crank for generating a proper pressing force, And a guide roller for pressing the lounges together with the louvers so as to maintain the left and right balances, so that the driving wheels are moved as they are in contact with the upper surface of the lounges to carry out the welding work.

Korean Patent Laid-Open Publication No. 2014-0010696 includes a main body, a traveling portion disposed at a lower portion of the main body and allowing the main body to travel on the upper surface of the rong, and a welding rod fixing arm protruding from both sides of the main body, To a continuous continuous weld carriage.

On the other hand, in the welding for assembling the hull block, the welding of the grounding part between the two members is mainstream, and the grounding part between the members forms a narrow space so that the welding device can not be inserted. There has been a demand for an automatic welding equipment capable of welding and satisfying the conditions of the right angle, acute angle and obtuse angle formed by the ground portion.
