Description

[0001] CARRIAGE APPARATUS [0002]

The present invention relates to a carriage apparatus, and more particularly, to a carriage apparatus that includes a long range processing function for moving a tool for a work in a long range and a carriage unit for moving the tool in a short range And a carriage device having a section processing function.

In general, welding has been used since about 1,000 years ago, but it has developed rapidly since the first and second world wars in many fields such as automobiles, vehicles, shipbuilding, architecture, electrical equipment, industrial machinery and metalworking And is particularly important in metal processing technology.

In particular, when the ship is dried, various thicknesses of steel plates are welded. At this time, the thick steel plate is not penetrated at once, and the steel plate is divided into the front surface and the back surface to perform the welding.

However, when one side is welded and then the other side is welded, a bone is formed in the direction of the weld line. When welding is performed on such a bone, the penetration is not properly performed, and the probability of welding failure increases. Therefore, a gouging operation is carried out in order to prevent such welding defects.

Most of this gouging is done by hand. That is, the operator carries out a gouging operation on the inside and outside of the block by holding the gouging torch by hand.

Such gouging operation according to the conventional technique requires an operator to carry a heavy gouging torch to perform work, resulting in an increased fatigue of the worker, which results in inferior gouging quality since the gouging width and depth are not constant.

Therefore, there is a need for a carriage device that moves a work tool such as a gouging torch and performs work. In addition, such a carriage device should be able to meet all of the various requirements in the work process (for example, fast operation in the long range and precise operation in the short range).

That is, a carriage device having a long range machining function for quickly moving a work tool in a long range and a short machining function for precisely moving a work tool in a short range is required It is true.
