Description

ISO tank container docking jig and method of assembling ISO tank container {ISO TANK CONTAINER DOCKING JIG AND METHOD OF ASSEMBLING ISO TANK CONTAINER}

The present invention relates to an ISO tank container docking jig and an ISO tank container assembly method, and more particularly, to an ISO tank container docking jig and an ISO tank container assembly method for efficiently assembling the inner and outer tanks of an ISO tank container without damage. will be.

As an alternative to environmental problems, many countries are studying the use of LNG (Liquified Natural Gas) as fuel.

LNG (Liquefied Natural Gas) and LPG (Liquefied Petroleum Gas) are chemically pure hydrocarbons, and are completely burned during combustion. LNG and LPG are clean fuels that contain a small amount of sulfur, and do not emit fine dust (PM10), and nitrogen oxides (NOx) are 95% and sulfuric acid when they are combusted compared to the conventional heavy fuel oil (HFO). Freight (SOx) is reduced by more than 90%. Therefore, LNG and LPG are clean fuels that can replace existing fuels such as gasoline, diesel oil, and heavy oil, and demand for them is expected to increase continuously.

In LNG, methane is the main component of 70-90%. In order to facilitate transport and storage of LNG, when the gaseous gas is cooled to -162 degrees and liquefied, the volume is reduced to 1 in about 700 minutes, and LNG is stored and handled as such liquefied gas in a tank.

LPG has a higher operating temperature than LNG and can be stored at room temperature depending on the storage pressure, so it is widely used worldwide. In addition, the volume of LPG is reduced to about 1/250 compared to gaseous gas, making it convenient for storage and transportation.

Such LNG or LPG can be handled by being filled in ISO tank containers and transported or stored. ISO tank containers are containers for liquids manufactured according to internationally promised standards such as IMO (International Maritime Organization) and ISO (International Organization for Standardization), and are containers made for transporting liquid food or chemical products, especially dangerous goods such as liquefied gas.

2 is a view showing an ISO tank container docking jig 100 according to an embodiment of the present invention.

In the ISO tank container manufacturing process, the inner tank 10 and the outer tank 30 are each manufactured, and the ISO tank container docking jig 100 may be used in a step in which they are combined. That is, the ISO tank container docking jig 100 surrounds the inner tub 10 and the inner tub 10 of the ISO tank container, and the inner surface is spaced apart from the outer surface of the inner tub 10 and is spaced apart from the inner tub 10 It can be used to assemble the outer tank 30 of the ISO tank container forming a space.

The ISO tank container docking jig 100 is preinstalled or set in one area in the process of the manufacturing process, and the inner tank 10 and the outer tank 30 can be transferred onto the ISO tank container docking jig 100.

The ISO tank container docking jig 100 includes a first roller 110, a second roller 120, a driving unit 130, and a support unit 140.

For example, the driving unit 130, the second roller 120, the first roller 110, and the support unit 140 may be arranged or set in order.

The outer tank 30 of the ISO tank container may be transferred and seated on the first roller 110. In this case, the outer tub 30 may be in a state in which the front and rear sides are opened, and the first roller 110 may be supported by contacting the lower half of the outer surface of the outer tub 30 from the lower side of the outer tub 30.

The inner tank 10 of the ISO tank container may be transferred and seated on the second roller 120. The second roller 120 is located in front of the outer tub 30 and may support the outer surface of the inner tub 10 so that the rear of the inner tub 10 faces the front of the outer tub 30 (see FIG. 6 ).

The driving unit 130 may pressurize the inner tub 10 so that the inner tub 10 moves on the second roller 120 and flows into the inner tub 30.

The support 140 may support the rear end of the inner tub 10 transferred to the inside of the outer tub 30 by the driving unit 130 from the rear of the outer tub 30.

In this way, the ISO tank container docking jig 100 is a manufacturer in which settings required for assembling the inner tub 10 and the outer tub 30, for example, setting the height of the inner tub 10 and the outer tub 30, etc. The inner tub 10 and the outer tub 30 are assembled using the 1 roller 110 and the second roller 120. Therefore, the inner tank 10 is moved or slid by the rolling action of the roller by a stable external force transmitted from the driving unit 130, so that the height can be very uniformly transferred to the ground.

That is, the interval between the inner tub 10 and the outer tub 30 is kept very uniformly and stably, and the inner tub 10 may flow into the inner tub 30. Therefore, compared to the process of assembling the inner tub 10 by moving the inner tub 10 with a crane, the time required for assembling the inner tub 10 and the outer tub 30 is greatly reduced, thereby greatly improving productivity. In addition, as described above, since the spacing is very constant, the case where the inner tub 10 collides with the outer tub 30 and is damaged can be substantially prevented.

3 is a diagram showing an example of a method of coupling the guide bar 141 to the inner tank 10 of the ISO tank container.

In particular, when the inner tank 10 flows into the outer tub 30, the portion of the inner tub 10 introduced into the outer tub 30 is not supported separately from the inside of the outer tub 30, so the ISO tank container of this embodiment The docking jig 100 supports the rear end of the inner tub 10 from the rear of the outer tub 30 to prevent the inner tub 10 flowing into the outer tub 30 from sagging downward.

In order to support the rear end of the inner tub 10 from the rear of the outer tub 30, the support 140 may include a guide bar 141 and a support roller 143.

The guide bar 141 is coupled to the rear end of the inner tub 10 and may be a pipe extending in the front and rear direction.

The guide bar 141 may include a bolt fastening portion 1411 that is coupled to the rear end of the inner tub 10, as illustrated in FIG. 3. At the rear end of the inner tank 10, a coupling portion 11 for coupling with the bolt fastening portion 1411 of the guide bar 141 may be formed. Since the bolt fastening portion 1411 is easily attached and detached from the coupling portion 11, the assembly process time can be very short.

4 is a view for explaining the rollers of the ISO tank container docking jig 100 supporting the inner tank 10 and the outer tank 30 of the ISO tank container.

The first roller 110 is positioned between the second roller 120 and the support roller 143 and may include a turning roller capable of rotating the outer tub 30 with the front and rear directions as an axis. Of course, the first roller 110 can be adjusted in height with respect to the ground, and may further include a fixing portion for fixing to the ground.

The second roller 120 may include a frame 121 extending in the front-rear direction and a plurality of rolling parts 123.

The frame 121 may be a plate-shaped support plate elongated in the front-rear direction.

The plurality of rolling parts 123 may be disposed on the frame 121 to be spaced apart from each other in the front-rear direction. The rolling part 123 may be fixed to the frame 21. The distance between each of the rolling parts 123 of the plurality of rolling parts 123 may be narrower as it is closer to the first roller 110.

The rolling part 123 of the second roller 120 may contact the lower half of the outer surface of the inner tank 10 in a direction inclined with respect to a substantially vertical line, as illustrated in the middle of FIG. 4. When the driving unit 130 presses the inner tub 10, the rolling unit 123 may be rotated by friction with the outer surface of the inner tub 10. Accordingly, the inner tub 10 can be very easily and easily transferred toward the outer tub 30 while maintaining a constant height with respect to the ground.

The first roller 110 may also support the outer surface of the outer tub 30 in the same manner as the second roller 120.

The driving unit 130 may be located on the frame 121. The driving unit 130 may include a motor unit 131 and a moving roller unit 133 that operate according to a signal transmitted from the outside. For example, the driving of the motor unit 131 may be controlled by manipulating the wired or wireless remote controller 170.

The moving roller unit 133 may move forward and backward on the frame 121 according to the operation of the motor unit 131, and may move toward the outer tub 30 by pressing the front end of the inner tub 10.

The support roller 143 may be located at the rear of the first roller 110. The support roller 143 is coupled to the rear end of the inner tub 10 as the inner tub 10 flows into the outer tub 30 by the driving unit 130, and the guide bar 141 protrudes to the rear of the outer tub 30 ) Can be supported.

Therefore, the rear end of the inner tub 10 located on the inner side of the outer tub 30 is supported by the guide bar 141 and the support roller 143, so that the inner tub 10 and the outer tub do not sag downward from the inside of the outer tub 30 The spacing between (30) can be kept very constant and stable.

5 is a flowchart of a method of assembling an ISO tank container according to an embodiment of the present invention.

Thereafter, the spacing between the outer surface of the inner tub 10 and the inner surface of the outer tub 30 is constant, so that it is introduced from the rear of the inner tub 10 to the inside of the outer tub 30 (S300).

Next, as the inner tub 10 flows into the inner tub 30, the rear end of the inner tub 10 is supported from the rear of the outer tub 30 (S400).

According to the method of assembling the ISO tank container, the time required for the assembly operation is significantly shortened, and damage due to collision between the inner tank 10 and the outer tank 30 is prevented. The ISO tank container docking jig 100 described in FIGS. 2 to 4 may be used to perform the method of assembling the ISO tank container.

6 is a view showing a state in which the inner tank 10 and the outer tank 30 are prepared on the ISO tank container docking jig 100 in the ISO tank container assembly method.

As described above, the ISO container docking jig 100 may be set in advance at a place necessary for the manufacturing process of the ISO container. The inner tub 10 and the outer tub 30 may be mounted on the first roller 110 and the second roller 120 by a transport device such as a crane.

Alternatively, a method of mounting the inner tub 10 and the outer tub 30 on the first roller 110 and the second roller 120 may be used. For example, a vehicle-type transport means carrying the inner tub 10 or the outer tub 30 is brought close to the side surfaces of the first roller 110 and the second roller 120, and the outer tub 30 and the inner tub 10 are It may be transferred onto the first roller 110 and the second roller 120.

The ISO tank container assembly method is between the process of positioning the front of the outer tub 30 and the rear of the inner tub 10 to face each other (S100) and the process of introducing the inner tub 10 into the inside of the outer tub 30 (S300). A guide bar coupling process (S200) of coupling the guide bar 141 to the rear end of the inner tank 10 may be further included.

For example, as illustrated in the middle of FIGS. 3 and 6, the guide bar 141 in the form of a pipe may be bolted to the rear end of the inner tub 10. At this time, a process of bolting the pipe-shaped support bar 150 to the front end of the inner tank 10 may also be performed.

7 is a view for explaining a process in which the inner tank 10 is inserted into the outer tank 30 in the method of assembling the ISO tank container according to an embodiment of the present invention.

The process of supporting the rear end of the inner tub 10 from the rear of the outer tub 30 (S400) protrudes to the rear of the outer tub 30 as the inner tub 10 is introduced into the inner tub 30 by the driving unit 130 It may include a process of supporting the guide bar 141 to be supported by the support roller 143, as shown in the lower figure of FIG. 4.

Before the front end of the inner tub 10 flows into the outer tub 30, the guide bar 141 may protrude to the rear of the outer tub 30, and the support roller 143 is a guide bar protruding rearward ( The 141 is supported from the lower side, but the guide bar 141 can be freely moved in the front and rear direction.

8 and 9 are diagrams for explaining a process after the inner tub 10 is inserted into the outer tub 30 in the method for assembling the ISO tank container according to an embodiment of the present invention.

As the inner tub 10 flows into the outer tub 30, the moving speed of the inner tub 10 is reduced by the driving unit 130, and the inner tub 10 moves to the inside of the outer tub 30 as shown in the upper figure of FIG. When the inflow is complete, the movement of the inner tank 10 can be stopped.

Thereafter, the outer tub 30 may be rotated in a state for assembly with the inner tub 10 using the first roller 110 (S500). For example, a plurality of openings for inserting the supporter 50 may be formed in the outer tub 30. The outer tub 30 may be rotated so that such an opening is aligned with a suitable position of the inner tub 10.

The upper figure of FIG. 9 shows a cross section cut so that the supporter 50 shown in FIG. 1 appears.
