Description

{SHIP FOR TRANSPRING CONTAINER}

The present invention relates to a container shipping vessel.

There are two general ways to supply natural gas to consumers. First, it is a way to supply natural gas directly to consumers through the natural gas pipeline. Secondly, it is a way to supply consumers with liquefied natural gas (LNG) through a tank lorry. The second method is commonly used when supplying natural gas to a remote location where the natural gas pipeline is not directly connected.

However, in the case of the second method, there is a disadvantage that a fixed storage tank must be separately installed at a remote place, and that the fixed storage tank has to be charged periodically with liquefied natural gas.

In addition, LNG bunker shuttle or container is the only way to supply LNG to the island area. The fact that there is no dedicated vessel to transport the container, the installation of dedicated cargo handling facilities on the quay for the unloading of containers, and harbor maintenance There is a problem that the complexity of the transportation process, the increase of the cost, and the reliability of the transportation process are deteriorated. Also, even in the case of the vertical movement of a general container, it is necessary to equip the container for the up and down movement of the container and other necessary space, and to freely move the container up and down freely regardless of the port facility, There is a need for dedicated vessels that can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a container ship according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a container T transporting ship according to an embodiment of the present invention, FIG. 2 is a partial plan view of a container transporting ship T according to an embodiment of the present invention, Fig. 2 is a partial schematic side view of a container (T) transport vessel according to an embodiment.

First, the container described in one embodiment of the present invention includes an ISO LNG (Liquefied Natural Gas) tank container, and is defined as including various kinds of containers.

A container T transporting vessel according to an embodiment of the present invention includes a loading space S on which a plurality of containers T are stacked on a deck of a ship and an outer transporting means S for vertically moving the container T, (11) in which a specific upper and lower space (L) is formed in which the moving object (V) enters and in which an entrance for entrance and exit of the external conveying means (V) is opened and closed; And a guide part (12a) including at least one pair of guide modules (12a) arranged at both ends in the width direction of the traveling direction of the external conveying means (V) so as to guide the external conveying means (12); A position adjusting section 13 formed inside the width direction of the guide module 12a and including a plurality of roller bearings 13a that are rotated in the width direction to correct the widthwise position of the external transfer means V; And a stop module (14) disposed at one end in the traveling direction of the up / down space (L) and restricting a position in the traveling direction of the external transport means (V) L to move up and down the container T to and from the external conveying means V. The guide rails 31 are coupled to the guide rails 31 formed at both ends of the ship parallel to the vertical space L, Includes a crane (20) which binds the binding portion (26) corresponding to the upper surface of the container (T) and moves the container (T) in the longitudinal direction and the width direction in which the guide rail (31) do.

1 and 2, a transportation ship according to an embodiment of the present invention includes a loading space S in which a container T is loaded on a deck thereof, Thereby forming a vertical space L.

In the loading space S, a plurality of containers T can be stacked three-dimensionally along the length, width, and height direction of the ship as shown in FIG. The lashing bridge 32 corresponding to the width of the vessel can be provided in the loading space S at a predetermined length interval corresponding to the length of the container T. The lashing bridge 32 is provided with the container T The plurality of containers T can be stably stacked by fastening them with fastening means (not shown). Further, the container T can be standardized so that the loading space S and the position where the container T is loaded can be modularized.

The upper and lower space L can be constructed by transporting the container T loaded in the loading space S to the outside of the ship or placing the container T to be loaded in the loading space S from outside the ship, And an external conveying means (V) for conveying the sheet to the inside is disposed. At this time, the external conveying means V means a conveying means such as a tractor in which the container T can be loaded, and may include an unmanned conveying means. The upper and lower space L is preferably formed at the end of the loading space S in the direction of the opening and closing rod 11 to be described later so that the moving line of the external feeding means V entering through the opening / And it is possible to efficiently use the loading space S without waste. The upper and lower spatial spaces L may be formed as a single unit as shown in the drawing, and may be formed in plurality according to the size of the vessel and the efficiency of the operation. However, in the present description, .

On the other hand, the external conveying means V needs to be accurately stopped in the vertical space L at a specific position. This is related to the efficiency of the operation, in which the binding portion 26 of the crane 20 to be described later can be quickly combined with the container T mounted on the external conveying means V. In the unloading operation, if the external conveying means V stops at a position other than a specific position, the container T can not be quickly loaded to the external conveying means V, The position of the container T may be dislocated, causing a serious safety accident such as the container T falling. Therefore, in order to increase the efficiency and stability of the operation, the external conveying means V needs to be accurately stopped in the vertical space L. This is because the opening and closing rod 11, the guide portion 12, the position adjusting portion 13 And a stop module 10 that includes a stop module 14.

The opening and closing rod 11 opens and closes an entranceway for allowing the external conveying means V to enter and exit into the vertical space L. 2 and 3, the opening and closing rod 11 connects the port and the deck of the shipping vessel, and the external feeding means V can enter the upper and lower space L have. When the up and down operation is completed and the transportation vessel sails, the opening and closing rod 11 rotates and closes the access road as shown in Fig. The opening and closing rod 11 may be formed on the side of the ship, but it is preferably formed at the stern of the ship so as to be moored in a narrow port of the book area and enter the external conveying means V.

2, at least one pair of guide modules 12a disposed at both ends in the width direction of the traveling direction of the external conveying means V that has entered through the open / close rod 11 . The pair of guide modules 12a guides the position in the width direction in which the external conveying means V should proceed. The external conveying means V is moved in the specified width of the vertical space L You can enter. It is preferable that the interval between the pair of guide modules 12a, that is, the width thereof, corresponds to the width of the external conveying means V or is formed slightly wider than the width.

On the other hand, even if the position of the external conveying means V in the width direction is primarily limited according to the guide of the guide portion 12, it is difficult to operate the external conveying means V of a large size, The widthwise center of the external conveying means V may not exactly coincide with the widthwise center of the vertical space L. [ 2, the position adjusting portion 13 includes a plurality of roller bearings 13a formed on the inner side in the width direction of the guide module 12a and rotating in the width direction, and the roller bearings 13a, The position in the width direction of the external conveying means V is secondarily corrected. By such correction of the position adjusting section 13, the center in the width direction of the external feeding means V can exactly coincide with the center in the width direction of the vertical space L. [ 3, the position adjusting unit 13 may be formed so that the left and right driving wheels R contact the roller bearings 13a before and after the external feeding means V, As shown in FIG. Accordingly, the position adjusting portion 13 may be continuously formed to cover the entire contact surface of the driving wheel R, and may be intermittently formed to cover the contact surfaces of the front and rear, left and right driving wheels R. [ The specific operation principle of the position adjusting section 13 will be described later.

The stop module 14 is configured to guide a position where it should stop in the traveling direction of the external feeding means V and is disposed at one end in the traveling direction of the vertical space L, . That is, as the external conveying means V advances until it reaches the stop module 14, the position of the external conveying means V in the longitudinal direction, which is the progress direction thereof, is limited, The vehicle can stop at a specified position in the vehicle. The stop module 14 may be formed protrudingly on the deck to limit the travel of the drive wheels R of the external transport means V and may be formed continuously or intermittently corresponding to the width direction of the external transport means V .

When the external conveying means V is disposed at the precise position of the specific upper and lower space L by the passage portion 10, the conveying means V is moved from the external conveying means V to the loading space S through the crane 20, (T), or a loading operation for moving the container (T) from the loading space (S) to the external transfer means (V) is performed.

The crane 20 is coupled to the guide rails 31 formed at both ends of the ship parallel to the vertical space L and moves along the guide rails 31 in the longitudinal direction of the ship as a whole. At this time, the guide rail 31 can be formed at the upper end of the outer side wall W of the ship, as shown in FIGS. 1 and 2, in order to use the deck of the ship as much as possible in the loading space S. In addition, the guide rail 31 can be formed directly on the inner deck D on the ship outer wall in accordance with the structure of the ship.

The movement of the crane 20 along the guide rail 31 can be achieved by driving the main roller 21a by contacting the main roller 21a formed at the lower end of the crane 20 with the guide rail 31. [

On the other hand, the crane 20 is for moving the container T, and the binding portion 26 corresponding to the upper surface of the container T is tied up so that the container T is moved up and down, And is moved in the width direction perpendicular to the longitudinal direction and the longitudinal direction to be formed. The container T in the loading space S is moved up and down through the crane 20 formed in the vessel and the container T vertically moved is moved to the outside transporting means V stopped in the up- To the inside and outside of the ship. Accordingly, it is not necessary to construct a separate port facility for the vertical movement of the container T, and the existing port can be used as it is, which can reduce the economic burden for transportation in the book area and the like.

According to the above-described configuration, a container T transporting vessel according to an embodiment of the present invention can provide a dedicated transport vessel having a loading space S on which a container T is loaded.

Hereinafter, the guide portion 12, the position adjusting portion 13 and the stop module 14 of the passage portion 10 will be described in detail with reference to FIGS. 4A to 5B, and a description overlapping with the above description will be omitted .

In this way, the operation principle for correcting the position in the width direction of the external feeding means V Will be described.

The position sensing unit 13b includes a position sensing unit 13b and a drive unit 13c. The position sensing unit 13b is connected to the drive wheels R of the external transfer means V, When the roller bearing 13a contacts the roller bearing 13a, senses the widthwise position of the external conveying means V through the roller bearing 13a to be pressed. The position sensing unit 13b is positioned at the lower end of the roller bearing 13a and is pressed by the roller bearing 13a to sense the position of the external conveying means V in the width direction. On the other hand, the position of the external conveying means V sensed by the position sensing unit 13b in the width direction is transmitted to the drive unit 13c, which drives the roller bearing 13a in the width direction Direction. As the roller bearing 13a is driven in the width direction, the driving wheels R of the external conveying means V contacting the roller bearings 13a are moved in the width direction, and the external conveying means V, Can be moved in the width direction. The drive unit 13c can independently drive the roller bearings 13a of the position adjusting units 13 when the position adjusting unit 13 is intermittent as shown in the figure, It is possible to correct the position of the external feeding means V in the width direction so as to coincide with the central axis.

4C is a partial plan view showing a modification of the guide portion 12 according to an embodiment of the present invention, and a modification of the operation principle for correcting the position in the width direction of the external conveying means V Explain.

The guide part 12 according to the modification may adjust the position in the width direction of the external conveying means V by adjusting the interval in the width direction in which the guide module 12a faces not only the at least one pair of the guide modules 12a, And further includes a pressing unit 12b and a supporting jaw 12c for correcting. One end of the pressing unit 12b is coupled to the outside of the pair of guide modules 12a to project a pair of guide modules 12a inward in the width direction. The other end of the pressing unit 12b is coupled to the supporting step 12c and is supported by the supporting step 12c so that the width of the pair of guide modules 12a can be adjusted in the width direction, The widthwise spacing of the guide module 12a is adjusted so that the position of the external conveying means V in which the driving wheel R contacts the roller bearing 13a can be corrected in its width direction. In addition, according to the modification, not only the position in the width direction of the external feeding means V is corrected but also both sides of the external feeding means V are pressed by the guide module 12a, .

On the contact surface of the guide portion 12 with the wheel side face of the external conveying means V in order to rest on the stop module 14 to be described later in a state of being fixed by the guide portion 12 in the width direction, The external transfer means V rotates in the direction of the stop module 14 of the external transfer means V so as to be movable in the direction of the stop module 14 in a state in which the guide portion 12 is pressed in the width direction, A separate roller bearing (not shown) may be coupled to minimize the number of the roller bearings.

5A and 5B are partial sectional views showing the operation of the stop module 14 before and after the operation of the stop module 14 according to an embodiment of the present invention. In this way, the stop module 14, which fixes the traveling direction of the external transfer means V, Explain.

The stop module 14 further includes a receiving groove 14a, a receiving sensing unit (not shown) and a restricting module 14b for fixing the traveling direction, i.e., the longitudinal direction, of the external feeding means V. [ The receiving groove 14a is inserted into the stop module 14 in the traveling direction of the external feeding means V and accommodates any one of the driving wheels R in the forward and backward directions of the external feeding means V. In this way, the reception sensing unit can receive the driving wheels R in the receiving recess 14a. The receiving sensing unit can sense the driving wheels R in the receiving recess 14a, So as to determine the presence or absence of the driving wheel R. [0050] The operation mode of the acceptance sensing unit may be variously changed within a scope that is obvious to a person skilled in the art without being a button type, and it is obvious that the change of the acceptance sensing unit is within the scope of the present invention. When the forward and backward driving wheels R are sensed to be received in the receiving recess 14a by the receptacle sensing unit, the receptacle sensing unit delivers the signal to the restraining module 14b, 14a on the driving wheels R. In this case, the restricting module 14b is formed on the open outer side of the receiving groove 14a, and protrudes inward in the width direction of the receiving groove 14a and is fastened to the wheel of the driving wheel R, Can be constrained. However, the present invention is not limited thereto, and the operation principle of the restricting module 14b may be variously changed.

As described above, the external feeding means V can be accurately positioned in the specific up / down space L by the position adjusting portion 13 or the guide portion 12, and the up / down operation can be performed quickly and stably Lt; / RTI > The width direction and the moving direction position of the external conveying means V can be fixed by the guide portion 12 and the stop module 14 so that the external conveying means V can be moved relative to the ship Since there is no movement, it is possible to smoothly work upside down work. In addition, since the external transfer means V is fixed to the ship, the external transfer means V can be loaded and navigated together with the external transfer means V. In addition to the container T, the external transfer means V for transferring the container T to / (V) to the area.
