Description

Railless horizontal welding carriage

The present invention relates to a welding carriage, and relates to a rail-free horizontal welding carriage configured to be welded to a horizontal butt joint formed inside the ship's double hull.

In general, the welding process in ships is one of the important processes that occupies about 60% of the shipbuilding process, and 250 ~ 400 hull blocks are made to build one ship, and there are countless horizontal intersections between each block. Will be formed. However, welding work is essential to effectively cope with the tendency of skilled welders and aging of workers due to 3D evasion due to poor working environment (welding fume, spatter, welding heat, etc.).

In this respect, it is a trend to miniaturize the welding device for welding large vessels or steel structures, and to improve productivity by maximizing the operation rate by automating, contributing to the safety and health of workers by replacing the poor working environment as a welding device, It is used to obtain a high quality welded part with precision and repeatability.

1 is a photograph of a conventional horizontal welding seam and manual welding. As shown in Figure 1, the position of the conventional horizontal weld portion is formed close to the floor, the welder is lying on the floor to weld as close as possible to the head near the weld. As a result, it is difficult to accurately observe the behavior of arcs and molten water, and it is difficult to smoothly move the body in the welding progress direction. Therefore, defects such as slag mixing and poor fusion are frequently generated in the weld metal. Since the long-term multi-layer welding of about 20m or more is performed 8 to 13 times in an unstable posture, the fatigue of work is very high, and the musculoskeletal disorders of the welder are seriously concerned.

It is a schematic diagram of the formation height of a horizontal weld seam. As shown in Figure 2, since the horizontal welding seam is formed at various heights from the bottom surface it is difficult to perform automatic welding and it is difficult to set the various welding torch angle (work angle, forward / backward angle).

Accordingly, the present invention is to solve the above problems, it is possible to carry out long distance welding just by moving the welding carriage near the weld without installing a separate rail, and to weld horizontally in response to the change in the height of the formation of various horizontal welding joints Not only can the aiming position of the torch can be easily changed, but also various welding torch angles (working angle, forward / backward angle) can be easily set at the aiming position of the welding torch, and the position of the welding torch in the up, down, front and rear directions during welding The aim is to provide a rail-free welded carriage that can be finely adjusted.

In order to achieve the above object, the rail-free horizontal welding carriage according to the present invention includes a traveling cart having moving wheels installed on both front and rear sides and a traveling motor for driving the moving wheels; A weaving mechanism unit positioned at one side of the upper portion of the traveling cart and having a welding torch coupled to the weaving shaft of the weaving motor and the weaving motor; In the welding carriage which is located in the upper portion of the traveling trolley, and comprising an operation panel for controlling the running of the traveling trolley and the weaving conditions of the weaving mechanism portion, the operation panel portion to set the working angle of the welding torch to a desired value. It is characterized in that it is provided with a center rotation function of the welding torch.

Here, the weaving mechanism unit is fastened to the weaving shaft of the weaving motor to set the forward / reverse angle of the welding torch to move the forward / reverse angle change rotation slider for adjusting the forward / reverse angle of the welding torch It may be further provided.

The apparatus may further include a front and rear adjustment slider installed on the traveling bogie to slide the weaving mechanism part in the front-rear direction of the traveling bogie to correspond to the formation height of the welding joint and to change the aiming position of the welding torch during welding. Can be.

It may be provided on the traveling cart, and further provided with a vertical adjustment slider for sliding the weaving mechanism part in the vertical direction of the traveling cart to correspond to the formation height of the welding joint and to change the aiming position of the welding torch during welding.

In addition, it is provided on the side of the traveling truck, it may further include a guide roller for tracking the welding feed direction.

The apparatus may further include a magnet handle for allowing the traveling truck to be absorbed by the welding target and to be movable.

The apparatus may further include a remote controller having a wireless control function for the operation panel unit to wirelessly control the traveling cart or the weaving mechanism unit.

According to the present invention, not only the aiming position of the welding torch can be easily changed, but also various welding torch angles (working angle, forward / backward angle) can be easily set at the aiming position of the welding torch, so that the formation height of various horizontal welding joints can be changed. In response to this, horizontal welding is possible automatically. Accordingly, welding productivity can be improved through welding automation, and musculoskeletal disease prevention and working environment are expected to be improved.

In addition, since the welding torch can be finely adjusted in the vertical direction and the front and rear direction during welding, high quality welding is possible in response to the gap between the blocks and the gap between the blocks generated in the inter-block mounting welding step. In addition, since the magnet handle is provided without a separate rail installation can be moved in the adsorbed state to the welding object, long distance horizontal welding operation is possible.
