Abstract
Description
The present invention relates to a submerged arc welding carriage, and more particularly, to a welding apparatus capable of performing curved welding in a welder specification known in the prior art, thereby dramatically improving process management techniques and techniques for shipbuilding marine and poultry structures To a submerged arc weld carriage capable of curving and straight traveling capable of securing global competitiveness.
Welding carriage is used to transport welding torch to body frame and it is widely used in shipbuilding industry and carving plant field where welding work is frequently performed, such as shipbuilding work and carving plant construction work, have. Such a welding carriage is moved by a rail provided separately or by a driving wheel which rotates in conjunction with a motor. The welding carriage moved by the driving wheel is disclosed in Korean Patent Publication No. 10-0894434 entitled " Automatic Carriage for Submerged Welding "(refer to Patent Document 1), Published Unexamined Patent Application No. 10-2008-0098697 entitled" Four Side Welded Carriage "(see Patent Document 2) Shinan Publ. No. 20-0410838 entitled " Automatic welding carriage "(see Patent Document 3).
In the conventional welding carriage 100 ', as the driving motor is vertically mounted on the body frame, a bevel is formed between the motor shaft of the driving motor and the
In the conventional welding carriage 100 ', as shown in FIG. 1, the
As such, the conventional welding carriage has a structure in which the rotational force is transmitted to the chain or the belt. Thus, the size of the body frame is increased to secure a space for the welding carriage, and the welding carriage can not be operated in a narrow space.
In addition, when a conventional welding carriage is applied to a manual welding torch and the manual welding torch is mounted and transported according to the judgment of the operator and the need, the operator repeatedly moves the welding carriage to a position where welding is required. The weight of the welding carriage is increased as the size of the welding carriage is increased, thereby increasing the worker's fatigue feeling when moving the welding carriage and increasing the incidence of musculoskeletal injury of the operator.
As a conventionally developed technique for solving the above-mentioned problems, a "gear-driven welding carriage" of Utility Model Registration No. 0456390 has been developed and disclosed in the published patent publication.
As shown in FIG. 2, in the
However, the above-mentioned " gear-driven welding carriage " in the utility model registration No. 0456390 has a problem that it is possible to carry out a curve (curved surface) welding operation because it is possible to perform straight running.
In other words, it is a stereotypical idea that the root technology known as submerged arc welding in park and heavy plate submerged arc welding is only possible to run straight. It can not overcome technical limitations (irregular or arc welding is not possible). Large structures in shipbuilding and marine plant And pressure vessel process technology have gradually developed in speed and pattern within the category. It enables arc welding (curved surface) welding to existing welding machine specification, which will dramatically improve the process management techniques and technology of shipbuilding marine and wooden structures and secure global competitiveness.
The present invention has been made to solve the various drawbacks and problems caused by the conventional submerged arc welding carriage in view of the above-mentioned circumstances, and it is an object of the present invention to provide a welding apparatus capable of arc welding To provide a submerged arc welding carriage capable of drastically improving preparation work, minimizing surveillance work, and reducing curtailment and unreasonable worries.
Another object of the present invention is to trace the weld line using a mechanism and an electronic control device for preventing the deviation of the weld line, thereby facilitating arc welding (curved surface welding) as well as straight welding, The present invention provides a submerged arc welding carriage capable of being curved and straight traveling which can actively change according to a groove weld line.
In order to accomplish the above object, a submerged arc welding carriage according to the present invention and capable of straight running includes a
The present invention is capable of curving and straightening the welding and welding process by minimizing the preparatory and monitoring work by making arc welding (curve welding) possible to the existing welding machine specifications, (Curved surface) welding as well as straight welding, it can reduce surveillance work by using 3 colors and can actively change according to groove welding line with free rollers. Therefore, There is a special advantage that the breakthrough of the process control technology of the pressure vessel production is achieved and the quality control of the welding is ensured and the reliability of the welding quality is improved.
