Description

  The present invention relates to a container terminal and a container terminal operation method, and more specifically, a container stored in a storage lane is rearranged on one end side of another storage lane, and the container is smoothly transferred from the storage lane to the transport cart. The present invention relates to a container terminal and a container terminal operating method for transferring and improving the cargo handling efficiency and reducing the work time required for relocation of containers.

  Various container terminals capable of rationalizing container handling have been proposed (for example, see Patent Document 1). The container terminal described in Patent Document 1 includes a plurality of storage lanes, a portal crane that travels across each storage lane, a plurality of orbiting carriages that travel between a quay apron region and a quay side position of the storage yard And a reciprocating carriage that travels along a track provided in the longitudinal direction of each storage lane. Then, containers are transferred between the reciprocating carts of the storage lanes and the circulating carts at the quay side of the storage yard, and the containers are transferred between the reciprocating carts of the storage lanes and the load chassis at the land side of the storage yard. Delivery is to be performed.

  The transfer operation of the container to the transport cart such as the circulating cart and the load chassis at the container terminal is performed on the end side of each storage lane. Therefore, in order to carry out the transfer work to the trolley truck and the load chassis smoothly when loading on the ship or carrying out to the outside of the container terminal, the containers stored in various locations of the storage lanes must be stored in each storage lane. It is desirable to rearrange at the end side.

  Also, in recent container terminals, loading / unloading of container ships is carried out on the quay at an efficiency of about 200 to 300 per hour, so only some storage lanes can be used when relocating containers in the storage area. It is desirable to make the number of containers rearranged equal to each storage lane so that the work of loading does not concentrate on the work and the work efficiency is reduced.

  When the containers are rearranged, it is necessary to move the containers between the storage lanes so that the number of the rearranged containers is equal for each storage lane. However, in the container terminal described above, it is necessary to use a portal crane, a reciprocating carriage, and an orbiting carriage when moving containers between the storage lanes.

  In particular, since the work of transferring the container to the circulating cart occurs, the efficiency of the work of rearranging the container is poor, and the time required for the work is also long.

  The portal crane 40A is a non-extendable portal crane having a trolley 43A that can move only in the upper region of the storage lane 7 where the portal crane 40A is disposed. The portal crane 40A has two legs 41A that are erected opposite to each other across the storage lane 7, a girder 42A that is suspended on the leg 41A and extends in the x direction, and moves on the girder 42A. A trolley 43A, and a spreader 44A that moves up and down via the trolley 43A. This leg 41A has a rubber tire 45A that rolls on the quay 2 at its lower end, and has a traveling device 46A that can freely travel in the direction of rotation of the rubber tire 45A in the horizontal direction. The portal crane 40A is an RTG (Rubber Tired Gantry Crane) that can automatically travel and remotely control loading and unloading of the container C, and includes a communication device 47A that can communicate with the control facility 11. .

  The reciprocating cart 50 includes a loading platform 51 on which the container C is mounted, a cart body 52, wheels 53, and a driving device 54. The reciprocating carriage 50 is an AGV (Automated Guided Vehicle) that travels on a set of traveling paths 8 formed of rails by wheels 53 provided with flanges. The reciprocating carriage 50 can reciprocate at a faster speed than the portal cranes 40A and 40B.

  As shown in FIG. 3, the portal crane 40B is an extended portal crane having a storage lane 7 in which the portal crane 40B is disposed and a trolley 43B that can move in the upper region of both adjacent storage lanes 7. is there. The portal crane 40B includes a leg body 41B, a girder 42B, a trolley 43B, a spreader 44B, a rubber tire 45B, a traveling device 46B, and a communication device 47B in substantially the same manner as the portal crane 40A. Further, the portal crane 40B is formed such that the width of each leg 41B in the y direction is wider than the leg 41A of the portal crane 40A, and the spreader 44B can pass between the legs 41B. In addition, the portal crane 40 </ b> B has a cantilever girder 70 that protrudes onto the storage lane 7 next to the storage lane 7 that straddles and can extend the movement range of the trolley 43 </ b> B to the storage lane 7 that is next to it.

  The cantilever girder 70 is attached to each of both end portions of the girder 42B in the x direction. This cantilever girder 70 has a girder cantilever part 71, and the girder cantilever part 71 has a cantilever structure protruding in the x direction from the end part of the girder 42B in the x direction. Further, the cantilever girder 70 includes a turning structure 72 for turning the girder cantilever portion 71 about the vertical direction that is the standing direction of the leg body 41B as an axial direction.

  As shown in FIG. 4, the turning structure 72 includes a rotating portion 73, a driving portion 74, and an engaging portion 75. The rotating portion 73 is disposed at the end of the girder 42B, and has a rotating shaft 76 whose axial direction is the vertical direction. The drive unit 74 has a hydraulic cylinder 77 having one end pivotally supported by the girder 42B and the other end pivotally supported by the girder cantilever portion 71. The engaging portion 75 has a lock mechanism 78 that engages the end of the girder 42 </ b> B and the end of the girder cantilever portion 71.

  In addition, a trolley extension rail 79 is laid on the upper surface of the girder cantilever portion 71.

  When extending the movement range of the trolley 43B by the cantilever girder 70, first, the communication device 47B receives a command from the control facility 11. Next, the hydraulic cylinder 77 expands based on the command. Next, the girder cantilever part 71 opened from the end in the x direction of the girder 42 </ b> B to the outside in the y direction rotates inward about the rotation shaft 76 as the hydraulic cylinder 77 extends. Next, the end surface of the girder 42B and the end surface of the girder cantilever portion 71 are in contact with each other, and the lock mechanism 78 is engaged at the same time. At this time, the trolley extension rail 79 is arranged on the extension line with respect to the trolley rail 48B laid on the upper surface of the girder 42B.

  As a result, the trolley 43B can move from the trolley rail 48B to the trolley extension rail 79 and move on the trolley extension rail 79, and this portal crane 40B is adjacent to the storage lane 7 on both sides of the gantry crane 40B. Up to the storage lane 7 is the cargo handling range.

  4 shows an example in which the girder cantilever 71 is moved by the hydraulic cylinder 77, it may be operated using a motor and a pinion gear. Further, the girder 71 may be rotated by 90 degrees or more when folded, but when rotated by 180 degrees, it is possible to minimize the size of the gap with the adjacent portal crane.

  As shown in FIG. 5, when the portal crane 40B having the cantilever girder 70 and the portal crane 40A moving in the y direction on the adjacent storage lanes 7 pass each other, the communication device 47B causes the control facility 11 to Is received, and the above operation is reversed to open the cantilever-type girder 70 so as to be folded to the girder 42B side. Thereby, the collision between the portal cranes 40B or between the portal crane 40B and the portal crane 40A can be avoided, and the portal crane 40B can be freely moved along the storage lane.

  Next, an operation method of the container terminal 1A will be described.

  As shown in FIG. 1, the unloading work (work for storing the container C from the ship S to the storage lane 7) is performed by the container C from the ship S anchored with the traveling direction in the x direction, the bridge crane 20 and the shuttle. This is an operation in which the carrier 30 and the portal crane 40A are transferred and stored in the order of the bridge crane 20, the shuttle carrier 30, the reciprocating carriage 50, and the portal cranes 40A and 40B.

  During the unloading operation, the container transported by the shuttle carrier 30 is transferred to the portal crane transfer region 12 and the reciprocating carriage so that the control facility 11 shortens the waiting time in the storage region 4 of the shuttle carrier 30. It is selected whether to transfer in the area 13 or not.

  Thus, this unloading operation is performed by the shuttle carrier 30 transferring the container through the two paths of the transfer area 12 for the portal crane and the transfer area 13 for the reciprocating carriage, and the container C from the bridge crane 20. The transportation efficiency is improved. The container C is stored in two paths: storage of the container C by the portal crane 40A or the portal crane 40B and storage of the container C by the portal crane 40A or the portal crane 40B via the reciprocating carriage 50. The storage efficiency of lane 7 is increased. Specifically, on the edge 2a side of the quay 2 of the storage lane 7, the reciprocating carriage 50 and the portal crane 40A or the gate type are stored directly by the portal crane 40A or the portal crane 40B without going through the reciprocating carriage 50. The time taken to transfer the container C to and from the crane 40B is shortened. On the other hand, on the opposite side of the edge 2 a of the quay 2, the time required for transporting the container C is shortened by transporting the container C utilizing the speed of the carriage 50.

  Note that the loading operation (the operation of loading the container C from the storage lane 7 to the ship S) is the reverse procedure of the unloading operation.

  The unloading work (work for transferring the container C from the storage lane 7 to the container truck 60) is performed so that the control facility 11 shortens the waiting time in the container truck transfer area 14 of the container truck 60. The container C stored in 7 is directly transferred by the portal crane 40A or the portal crane 40B, or the container C stored in the storage lane 7 is moved from the portal crane 40A or the portal crane 40B via the reciprocating carriage 50. It is determined whether the transfer is performed by the portal crane 40A or the portal crane 40B. The carrying-in work (work for storing the container C from the container truck 60 to the storage lane 7) is the reverse procedure of the carrying-out work.

  Next, the rearrangement work performed before the loading work is started will be described. This rearrangement operation is an operation for rearranging the containers stored in the storage lanes 7 to the end of the storage area 4 on the edge 2a side of the quay 2. The ends of the storage area 4 on the edge 2a side of the quay 2 are the rearrangement areas 15 and the transfer areas 12 for the portal cranes.

  In the following description, among the storage lanes 7 arranged in three rows, the lanes in which the gate-type crane 40A and the gate-type crane 40B are sequentially arranged from the sea side to the land side are 7a and 7c, and the storage lanes thereof. 7b is a lane that is arranged between 7a and the storage lane 7c and in which the portal crane 40B and the portal crane 40A are sequentially arranged from the sea side to the land side. Further, areas adjacent to the storage lanes 7a to 7c are distinguished by adding a to c after each code.

  First, the control facility 11 confirms the storage status of the containers C stored in the storage lanes 7a to 7c, and creates a rearrangement diagram of the containers C. Next, the control facility 11 instructs the portal crane 40A, the portal crane 40B, and the reciprocating carriage 50 based on the rearrangement drawing.

  When the container C stored in the storage lane 7a is rearranged in the rearrangement area 15a of the storage lane 7a and the transfer area 12a for the portal crane, the portal crane 40A and the portal crane straddling the storage lane 7a 40B and the reciprocating carriage 50a moving along the storage lane 7a transport the target container C in the y direction, and then the portal crane 40A or the portal crane 40B transfers the container C to the rearrangement region 15a or the portal type. Relocate to the crane transfer area 12a.

  In addition, when the container C stored in the storage lane 7b is rearranged in the rearrangement area 15b of the storage lane 7b and the transfer area 12b for the portal crane, the container C stored in the storage lane 7c is relocated to the storage lane 7c. The same applies to the rearrangement in the placement area 15c and the gate crane transfer area 12c.

  In this rearrangement operation, when the container Ca stored in the storage lane 7a is rearranged in the storage lane 7c, the container Ca is moved from the storage lane 7a to the storage lane 7c using the portal crane 40B having the cantilever girder 70. Move between.

  First, as shown in FIG. 6, the portal crane 40B straddling the storage lane 7b instructed by the control facility 11 moves the cargo handling range of the trolley 43B from the upper region of the storage lane 7a to the storage lane 7c by the cantilever girder 70. Spread to the upper area. Next, the portal crane 40B moves the trolley 43B onto the container Ca stored in the storage lane 7a, and lifts the container Ca by the spreader 44B. Next, the portal crane 40B moves on the trolley 43B from the storage lane 7a to the reciprocating carriage 50c traveling along the storage lane 7c.

  At this time, when the target container Ca is outside the handling range of the portal crane 40B, the portal crane 40A straddling the storage lane 7a or the portal crane 40B (not shown) is targeted up to the handling range. Move the container.

  Next, as shown in FIG. 7, the portal crane 40B lowers the spreader 44B and transfers the container Ca to the reciprocating carriage 50c. Next, the reciprocating carriage 50c travels in the y direction and transports the container Ca to the reciprocating carriage transfer area 13c.

  Next, as shown in FIG. 8, the portal crane 40A straddling the storage lane 7c receives the container Ca from the reciprocating carriage 50c and rearranges it in the rearrangement region 15c of the storage lane 7c.

  The number of containers C rearranged at the end of the storage area 4 on the edge 2a side of the quay 2 is substantially equal for each storage lane 7a to 7c, that is, rearranged in each of the rearrangement areas 15a to 15c. This relocation operation is completed until the number of containers C and the number of containers C rearranged in the portal crane transfer areas 12a to 12c become equal.

  According to the container terminal 1A and its operation method, the container Ca can be moved from one storage lane 7a to the other storage lane 7c by the portal crane 40B having the cantilever girder 70. Thereby, the relocation work for equalizing the number of containers C in the storage lanes 7a to 7c at the edge 2a side end of the quay 2 of the storage area 4 can be completed without using a carriage such as the shuttle carrier 30. Therefore, the work time required for this rearrangement work can be shortened.

  Moreover, the amount of energy consumed at the container terminal 1A can be reduced by reducing the work time required for the rearrangement work.

  In addition, by performing the rearrangement operation, the containers C to be loaded in the rearrangement regions 15a to 15c and the gate crane transfer regions 12a to 12c are rearranged equally. As a result, it is possible to avoid the concentration of work in some storage lanes, and the container C can be smoothly transferred to the shuttle carrier 30 after the loading operation is started. can do.

  Furthermore, the container C transported to the outside of the container terminal 1A can be rearranged. In the conventional container terminal, the container C cannot be moved between the storage lanes 7 unless it passes through the quay 2 side, that is, through the shuttle carrier 30. In this regard, the container terminal 1A can move the container C between the storage lanes 7 using the portal crane 40B having the cantilever girder 70, so that the container C can be easily rearranged. Thus, cargo handling efficiency can be improved.

  As shown in FIG. 9, in the container terminal 1B of the second embodiment, a storage lane 7 in which a plurality of portal cranes 40C each having a cantilever girder 70 is arranged and a storage lane 7 in which a plurality of portal cranes 40A are arranged are one. It is the structure arranged every other.

  As shown in FIG. 10, the portal crane 40C is similar to the portal crane 40B in that the leg 41C, the girder 42C, the trolley 43C, the spreader 44C, the rubber tire 45C, the traveling device 46C, the communication device 47C, and the cantilever girder. 70.

  The portal crane 40C is formed such that the height H1 of the lower end surface of the girder 42C and the cantilever type girder 70 from the ground is higher than the height H2 of the upper end surface of the girder 42A of the portal crane 40A from the ground. The

  Thereby, when the portal crane 40C and the portal crane 40A pass each other, the collision between the portal crane 40C and the portal crane 40A can be avoided without driving the cantilever girder 70.

  In the embodiment, an example in which the storage lane 7 extends in the direction y along the storage lane has been described. However, when the storage lane 7 is applied to a quay specification or a conventional container terminal, the storage lane It is good also as a structure extended toward x direction.

In the above-described embodiment, the example in which the shuttle carrier 30 is used as the circulating carriage has been described. However, the present invention is not limited to this. For example, a straddle carrier that can stack containers C at a height of two or more levels can be used. Moreover, the conveyance trolley | bogie which does not have hanging tools, such as a spreader, can also be used. However, in the case of using a transport carriage, it is preferable to provide a transfer stand in the transfer area 12 for the portal crane or the transfer area 13 for the reciprocating carriage.

  In the above embodiment, the example using the reciprocating carriage 50 that can reciprocate the traveling path 8 adjacent to the storage lane 7 in the x direction and laid in the y direction has been described. It is also applicable to container terminals that do not have However, by transporting the container C with the reciprocating carriage 50 having a higher moving speed than the portal cranes 40A and 40B, the distance that the portal cranes 40A and 40B move by suspending the container C is shortened, and the handling efficiency is improved. can do.

  Moreover, in said embodiment, although the cantilever type girder 70 was demonstrated as an example as an extension type girder which extends the moving direction of a trolley, this invention is not limited to this. For example, instead of the cantilever type girder 70 described above, a cantilever type girder that undulates in the direction of standing of the leg of the portal crane may be provided as an extended girder. Moreover, you may provide the slide type girder which expands-contracts in the x direction which is the extending direction of a girder as an extended type girder.

  Therefore, when the extension-type gate crane and the gate-type crane arranged in the adjacent storage lane pass each other in the extension direction of the storage lane, the control in which the extension-type girder turns as in the embodiment, By performing either control that occurs in the standing direction of the leg of the portal crane or control that contracts in the extending direction of the girder, mutual collision can be avoided.

  In addition, in the above embodiment, the cantilever girder 70 is provided on both sides of the girder 42B or 42C, but it may be provided on only one side.

  Further, in the above embodiment, the description has been given by taking as an example a configuration including both the portal crane 40B or 40C having the cantilever girder 70 and the portal crane 40A not having the cantilever girder 70, but the gate of the container terminal A configuration may be adopted in which all the cranes are portal cranes 40B or portal cranes 40C.

  However, even if not all of the portal cranes are the portal crane 40B or the portal crane 40C, the double crane 40B or the portal crane 40C is at least horizontal as in the configuration of the first embodiment or the second embodiment. If it is arranged in every other storage lane 7, the number of the extension type gate crane 40B or the gate crane 40C can be reduced, which is advantageous in terms of cost. In particular, when it is introduced into a conventional container terminal, it is possible to make the moving path of the container C into a lottery shape simply by introducing several portal cranes 40B or 40C, thereby improving the efficiency of relocation work. can do.
