Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a submerged arc welding carriage capable of curved and straight traveling,

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 wheel shaft 2 to which the driving wheel 1, A gear 3 is provided so that a rotational force can be transmitted between the drive motor 1 and the drive motor which are perpendicular to each other.

In the conventional welding carriage 100 ', as shown in FIG. 1, the wheel shafts 2 and 2' provided at both ends of the body frame 4 in the longitudinal direction are connected to the chain 5 or the belt, The wheel shaft 2 corresponding to the drive shaft is connected to the drive motor and the bevel gear 3 as described above and the wheel shaft 2 'corresponding to the driven shaft is connected to the chain 5 or belt as described above And the rotational force is transmitted from the wheel shaft 2 corresponding to the drive shaft.

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 welding carriage 100 in which the welding torch is mounted and transported, the torch mounting portion 50 on which the welding torch is mounted, A body frame 10 formed with a body 10; A driving wheel 20 fixed to the wheel shaft 22 so as to be rotatable in both forward and backward directions on the body frame 10; A driving motor (30) having a motor shaft (32) fixed to the body frame (10) and rotating the driving wheel (20); And a controller 60 for controlling the driving of the driving motor 30. A gear box 40 is provided between the driving motor 30 and the driving wheel 20, Is transmitted to the driving wheel (20) by the gear box (40).

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.
