Description

LNG STROGE Tank equatorial insert piece cutter apparatus

The present invention is designed for the production of aluminum tanks for the storage of liquefied natural gas in the hull structure during moss-type liquefied natural gas transportation. It is installed for the smooth progress of auto mig welding in the welding improvement shape installed in the center part (EQ) to weld the skirt (SKIRT) to the center part of the aluminum tank for the thickness difference and the separation between the aluminum storage tank and the hull. The present invention relates to an insert piece removal device for removing an insert piece after welding is completed. In particular, by using a holder equipped with a grinder and a multi-axis adjusting device, it maximizes workability and reduces worker fatigue to prevent musculoskeletal disorders and safety accidents. And it relates to a removal device for reducing the work maneuver.

1 is a view of the insert piece installed in the shape of the L-engine storage tank, the center section and the central improved portion, Figure 2 shows a picture of the insert piece installed in the L-engine block, conventionally, the grinder by the operator during the insert piece removal operation There is a problem of narrow / unsafe working posture, increased fatigue when working for a long time, a lot of safety accidents, and a lot of air input and air delay.

The object of the present invention for solving the above problems is the central part of the block joint (JOINT) welding work for manufacturing an aluminum tank for the storage of liquefied natural gas in the hull structure when the ship for moss-type liquefied natural gas transport ship (EQ) Auto in the welding improvement shape installed in the center (EQ) to weld the difference between the thickness of the plate and the upper / lower plate and the SKIRT in the center of the aluminum tank for the isolation between the aluminum storage tank and the hull. In order to remove the insert piece, which is installed for the smooth progress of MIG automatic welding, the operator lifts and removes the grinder by hand, and installs and removes the device using a separate mechanical movement. Adjustment handle, multi-axis configured to adjust the position and angle of the grinder with the cutting blade mounted on the holder By developing and removing the device while the worker adjusts it, it reduces the worker's fatigue caused by long work due to anxiety of the working posture, prevents the risk of musculoskeletal diseases and safety accidents, and is introduced during manual grinding work. It is to provide an insert piece removal device in the center of the LNG storage tank that can reduce the cost.

If described in detail in connection with the accompanying drawings the configuration and the operation of the embodiment of the present invention to achieve the object as described above and to perform the task for removing the conventional drawbacks.

7 is a plan view of the insert piece removal device of the present invention, Figure 8 is a front view of the insert piece removal device of the present invention, Figure 9 shows a side view of the insert piece removal device of the present invention, when explaining the configuration of the present invention (LNG) ALUMINIUM Install the insert piece for smooth welding in the center of the tank block (Fig. 2), and install the both blocks, and then perform the AUTO MIG automatic welding (Fig. 3) work. In order to remove the insert piece after performing (Figs. 4 and 5), the apparatus using the guide roller 11, the roller 8 and the bearing 9 to the pipe rail 14 for welding machine movement in which the apparatus of the present invention is installed. SETTING,

The grinder 10 fitted with the cutting blade is mounted on the holder HOLD 12, and then the traveling motor 7 is operated to engage the rack gear of the pipe rail 14 for welding movement with the pinion gear 15 of the present invention. Configured to drive the removal device to the height of the insert piece (Fig. 3),

Holder upper and lower adjustment parts (1), holder left and right adjustment parts (2), holder front and rear adjustment parts (3), grinder front and rear rotation parts (4), grinder left of the present invention for insert piece removal Adjusting the steering wheel of the DRIVE part 6, which is multi-axially configured to adjust the position and angle of the right rotating part 5, the cutting blade mounted on the holder, the cutting blade to match the initially improved shape. It is configured to grind by adjusting and adjusting the angle and position of the grinder.

To explain in more detail, the present invention is installed by removing the device by aligning the guide roller 11 to the pipe rail for moving the welder 14 and then operating the driving motor 7 the device travels in the upper direction.

At this time, if the removal device rises to the height where the insert piece is installed, the driving stops, adjust the handle of the holder front and rear adjustment part (3) to align the cutting blade with the insert piece, and adjust the holder up / down adjustment part (1). Align the cutting blade with the handle under the insert piece and start the grinder.

When the cutting blade of the grinder starts to remove the insert piece, move the holder left and right adjustment part (2), the grinder front and rear rotation part (4), the grinder left and right rotation part (5), and the lower part. Using the handle of the drive part (DRIVE) 6, the insert is inserted into an improved shape that was initially constructed while moving the holder forward, backward, left, right, up and down (forward, backward rotation and left and right rotation). The piece can be removed.

In particular, this device is equipped with a grinder that the worker was working on by hand on a separate device, and the operator operates only the handle of the adjusting device, reducing worker fatigue, eliminating worker tax instability, preventing musculoskeletal diseases, and reducing labor. It is a useful design that has a very good effect.

3 is a picture of the use of the insert piece when welding the block joint and a rail for moving the welder, FIG. 4 is a picture of the first removal of the protruding portion of the insert piece installed for automig welding, and FIG. 5 using a removal device. The insert piece installed inside the improved shape has been completely removed and removed in the same shape as the improved shape that was initially installed. FIG. 6 is a picture of the grinder device used to remove the insert piece before and after the improvement. It can be seen that the grinding device is removed by grinding by the removal device of the present invention.

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

The present invention as described above by using a device that combines the mechanical movement of the work to remove the insert piece by the operator holding the conventional grinder (GRINDER) by hand, reducing worker fatigue, preventing musculoskeletal diseases and safety accidents This is a very useful design that is expected to be used industrially because it has an excellent effect of reducing the number of pieces removed.
