Description

  The present invention relates to a quay crane that unloads cargo to a ship that is berthed on a quay, and simultaneously handles adjacent cargo on the ship at a time, and the quay that shortens the travel route of a transport carriage on which the quay crane delivers the cargo. The present invention relates to a container terminal equipped with a crane and a control method thereof.

  A quay crane is installed on the quay of a port and loads and unloads cargo such as containers, and is installed in most of the port and is one of the machines indispensable for cargo handling. Currently, with the rapid development of freight transportation systems on international routes, it is necessary to expedite cargo loading and unloading work on quay cranes.

  In order to speed up the cargo loading / unloading operation, loading / unloading of cargo with a plurality of quay cranes can be performed on a ship, thereby increasing the efficiency of cargo handling. However, in the conventional quay crane, the quay crane cannot be arranged with respect to the cargo arrangement on the ship due to the size of the quay crane.

  As shown in the plan view of FIG. 10, the conventional container terminal 110 includes a quay crane 100, a cruising crane 100 that travels on a track 101 laid on the quay 1, and leg portions 103. And a digit part 104. The leg part 103 supports the girder part 104, and the girder part 104 includes a boom 105 and a trolley 106 that moves on the boom 105. Here, the moving direction of the trolley 106 of the quay crane 100 is defined as a transverse direction X, and the direction of traveling on the track of the quay crane 100 is defined as a traveling direction Y. As shown in the rear view in the transverse direction X of FIG. 11, the trolley 106 (not shown) is provided with a spreader 107 which is a device for grasping the container k.

  However, the container terminal 110 cannot simultaneously load the container rows k1 to k4 adjacent to the traveling direction Y of the quay crane 100 on the ship 2. The width h1 of the ISO standard container is 40 feet (about 12.19 m), and the interval h2 between the adjacent container row k1 and the container row k2 is set to about 1.5 m to 2.0 m. On the other hand, since the quay crane 100 delivers the container k between the leg portions 103 to the transport carriage 108, the width h3 between the leg portions 103 is formed to be larger than 40 feet. In addition, the width h4 of the column portion of the leg portion 103 is added, and furthermore, the traveling device 102 is spread outward in order to release the weight of the quay crane 100, and has a width h5 of about 4 to 5 m from the leg portion 103. It protrudes to the outside by the amount. Therefore, the total width h6 of the quay crane 100 is longer than the length obtained by adding h1 and h2. As shown in FIG. 11, the adjacent quay cranes 100 can be arranged only for every other container row k1 to k4 in the traveling direction Y. Therefore, it was not possible to work on the container rows k1 to k4 adjacent to the traveling direction Y at a time. For example, when the containers k in the container rows k1 to k4 are unloaded, there is conventionally only a method of unloading the container row k2 and the container row k4 after unloading the containers k in the container row k1 and the container row k3.

  Thus, there is a container crane that can load and unload two 40-foot containers adjacent to the traversing direction X on the ship at a time (for example, see Patent Document 1). Since two containers can be loaded and unloaded at a time, the number of reciprocations of the trolley traveling on the boom is reduced, and the loading and unloading work can be performed more quickly than before.

However, even the container terminal provided with the container crane described in Patent Document 1 cannot solve the problem that the container adjacent to the traveling direction Y on the ship cannot be handled. In addition, the container crane described in Patent Document 1 has a heavy weight, and requires a quay civil engineering work that fully considers it, so that there is a problem that it is difficult to put into the existing quay. In addition, since a mechanism for loading and unloading two containers at the same time is installed, the manufacturing cost is higher than the conventional container crane and the maintenance cost is higher, and the operation is more complicated than before. Therefore, there is a problem that it is difficult to master the operation.

Special table 2008-516865 gazette

  The present invention has been made in view of the above-described problems, and the object of the present invention is to be able to unload containers adjacent to the traveling direction of a quay crane on a ship at a time and complete the loading operation in a short time. To provide a container terminal equipped with a quay crane. Moreover, it is providing the container terminal which can also shorten the travel distance of the conveyance trolley which the quay crane delivers a container. Furthermore, it is providing the control method with high cargo handling efficiency of the container terminal provided with the quay crane.

Container terminal of the present invention to solve the above problems, and runs over the track, the container terminal provided with a quay crane handling containers against a ship, at least two pairs of the track substantially parallel to each other provided, composed each of the adjacent quay crane, are alternately arranged to travel on different said track.

  According to this structure, since each adjacent quay crane is alternately arrange | positioned on the mutually different track substantially parallel, a mutual boom can be made to approach. Therefore, the container adjacent to the traveling direction of the quay crane on the ship can be handled. If the quay cranes are provided in the number of rows of containers arranged in the traveling direction of the quay crane on the ship, the container can be loaded / unloaded on the ship at a time, and the loading efficiency is dramatically increased.

  In addition, the container terminal is a rear view in the transverse direction of the quay crane, and at least a part of each leg part or traveling device of the adjacent quay crane overlaps, and between the ship and the track near the ship. The quay crane is provided with a quay delivery area for delivering containers to the transport cart.

  According to this configuration, adjacent quay cranes can travel on different tracks, and the legs or part of the traveling device overlap in rear view in the transverse direction, so the container adjacent to the traveling direction of the quay crane on the ship. Each boom can be placed on top. Therefore, the container handling of the container adjacent to the running direction of a quay crane can be performed. For example, if each track is formed by a pair of rails and a sea rail or a land rail of the second rail is provided between the sea rail and the land rail of the first rail, Between the sea-side leg and the land-side leg of the traveling first quay crane, the sea-side leg or the land-side leg of the second quay crane traveling on the second rail is disposed, and adjacent quay cranes Can approach the limit where it can operate. Moreover, according to said structure, the area where a quay crane delivers a container with respect to a conveyance trolley is provided between the rail closest to a ship and a ship, and the delivery of the container to a conveyance trolley is performed smoothly. Can do. Furthermore, since the container is not passed between the legs by providing the quayside delivery area, the cargo handling work can be facilitated.

  In addition, the container terminal is configured by providing the track on which the quay crane travels on a bridge-like gantry provided with at least one opening through which the transport carriage can pass.

  According to this configuration, since the transport cart that had to go around all the quay cranes to deliver the container can pass through the track of the quay crane, the transport cart is from end to end of the quay crane one by one. Never run. Therefore, the travel distance of the transport cart is shortened, and the container delivery work can be shortened accordingly. Moreover, the weight limit of the crane due to the hardness of the ground can be relaxed by sharing the weight burden of the crane with the bridge-like mount. When the track is formed of rails, it is necessary to reinforce the ground below the rails. However, according to this configuration, it is only necessary to reinforce only under the column portions that serve as the piers of the bridge-like gantry. The bridge mount may be formed in a wall shape provided with a tunnel through which a transport carriage can pass, in addition to being formed by combining pillars.

Container Terminal Another embodiment for solving the above problems, and runs over the track, the container terminal provided with a plurality of quay crane handling containers relative to the ship, the quay crane on the track At least one of which a trolley traverses and a trolley that traverses, the leg portion is omitted, and the spar is directly joined to the upper end of the traveling device, and the conveyance carriage can pass through the lower portion . An opening is provided, the track is laid on the top, and a plurality of the quay cranes are arranged on the track so as to be arranged in the traveling direction of the traveling device , and the quay crane is transported A wharf delivery area for delivering containers without passing through the bridge-like pedestal between the girder and the bridge-like pedestal is provided between the ship and the bridge-like pedestal. Ru

  According to this structure, the quay crane which consists of the girder part provided with the boom and the trolley, and the traveling apparatus, and which excluded the leg part can be made to drive | work on the track | truck provided on the bridge-shaped mount. Since the boom can be arranged on a container adjacent to the traveling direction of the quay crane on the ship, the container can be handled at a time. In addition, when unloading containers adjacent in the traveling direction of a quay crane on a ship at a time, the adjacent quay cranes do not overlap with each other as described above in the transverse direction, and the operation is facilitated. Can do.

Container Terminal Another embodiment for solving the above problems, and runs over the track, the container terminal provided with a plurality of quay crane handling containers relative to the ship, the quay crane on the track A traveling device that travels along the trolley, a girder that traverses the trolley, a leg portion that is joined to the lower end and supports the leg portion at the upper end, and a standing portion that faces the traveling direction of the traveling device. A joining member that joins the legs together, the joining members are disposed at the upper and lower ends of the legs , and the joining members at the upper and lower ends are shortened in the traveling direction, and the transverse direction of the quay crane container viewed from the rear, the width of the traveling device is also inclusive of quay crane is formed to fit within 12.192 meters to the quay crane transport vehicle, without let pass through between each other the legs The quay transfer area for transferring a ship constructed arranged between the sea side leg of each of said quay crane.

  According to this configuration, by forming the quay crane with a narrower width than before, the boom of each quay crane can handle a container adjacent to the traveling direction of the quay crane on the ship. Further, since the conventional track can be used as it is, no new track is laid.

  The container terminal control method of the present invention for solving the above-mentioned problem is a container terminal comprising a plurality of quay cranes for handling containers to a ship, and a plurality of transport carts to which the quay cranes deliver containers. In the control method, at least two tracks that are substantially parallel to each other are provided, each of the adjacent quay cranes travels on a different track, and handles containers adjacent to the traveling direction of the quay crane on a ship, In the quay delivery area provided between the ship and the track near the ship, the container is delivered to the transport cart.

According to this method, the container adjacent to the traveling direction of the wharf crane on the ship is handled at a time, and the container is transferred between the legs of the wharf crane to the transport carriage. By carrying out in the area between the container and the container on the ship, the container can be delivered to the transport cart even if the container is loaded at a time.

  In addition, the container terminal control method may be configured such that the transport cart passes through the opening of the bridge-like mount having the track on which the quay crane travels, and the quay delivery area and the area where the container is stored. Travel between and deliver containers.

  According to this method, the transport cart can pass through the opening provided in the bridge mount and the container storage area and the quay delivery area without going around the bridge mount. The travel route can be shortened. Conventionally, in order to avoid a collision with a quay crane moving along the quay, the transport cart circulates all the quay cranes to bypass the quay crane. However, according to this method, since the quay crane moves on the bridge-like gantry and the conveyance carriage passes through the opening provided in the bridge-like gantry, the entry path of the conveyance carriage is not disturbed by anything. Therefore, since each conveyance cart can be loaded and unloaded at each quay crane in the shortest time, cargo handling efficiency can be increased.

  According to the present invention, since the booms of the adjacent quay cranes can be made closer than before, containers adjacent to the quay crane traveling direction on the ship can be unloaded. Work efficiency can be increased. In addition, the traveling distance of the transport carriage can be shortened and the cargo handling efficiency can be increased.

  Hereinafter, a container terminal and a control method thereof according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the container terminal 30 according to the first embodiment of the present invention includes quay cranes 10, 20, tracks 11, 21, and a quay delivery area 40. The vehicle travels inside the container terminal 30.

The first quay crane 10 includes travel devices 12a and 12b that enable the first track seaside rail 11a to travel, travel devices 12c and 12d that enable the first track landside rail 11b to travel, and a sea leg 13a. The leg part 13 which consists of the land side leg part 13b, and the girder part 14 provided on the leg part 13 are provided. The girder 14 includes a boom 15 and a trolley 16 that moves the boom 15. The second quay crane 20 is the same as the first quay crane except for traveling on the second track 21.
However, since the second quay crane 20 is farther from the ship 2 than the first quay crane, the boom 25 may be formed longer than the boom 15 of the first quay crane 10. The quay cranes 10 and 20 of this invention are not restricted to said structure, For example, you may form the boom 15 separately with a boom on the ship side, and a girder on the land side so that the boom 15 can be flipped up. Moreover, a low profile crane etc. may be sufficient.

  Moreover, as shown in FIG. 2, the trolleys 16 and 26 (not shown) are provided with suspenders 17 and 27 for winding and lowering the container k, respectively. Although the spreaders 17 and 27 are suitable for spreading and lowering the container k, they can be replaced with hook blocks, grab buckets, lifting magnets, etc., and the quay cranes 10 and 20 of the present invention are used for cargo handling. The cargo is not limited to container k.

  As shown in FIG. 1, the first tracks 11a and 11b and the second tracks 21a and 21b are substantially parallel to the quay 1 (to the traveling direction Y) and substantially parallel to each other. The first track sea side rail 11a, the second track sea side rail 21a, the first track land side rail 11b, and the second track land side rail 21b are laid from the quay 1 in this order. The first track 11 and the second track 21 are formed by rails, but may be substantially parallel to each other as long as the quay cranes 10 and 20 can be driven, and are not necessarily formed in a rail shape.

  As shown in FIG. 2, the lateral width of the leg portion 13 near the beam 14 is made narrower than 40 feet, which is the lateral width of the container k, and the traveling devices 12 a to d and the traveling devices 22 a to d of the leg portion 13 are closer to each other. The width (width) should be wide. By doing so, the weight of the quay cranes 10 and 20 can be disperse | distributed with traveling apparatus 12a-d and traveling apparatus 22a-d. Moreover, when forming the wide width toward the traveling devices 12a to 12d and the traveling devices 22a to 22d, during the loading and unloading of the strut that joins the sea side leg 13a and the land side leg 13b of the first quay crane. Form so as not to collide.

When the first quay crane 10 is placed on the first track 11 and the second quay crane 20 is placed on the second track 21 , as shown in FIG. 1, the first quay crane 10 and the second quay crane 20 are staggered in plan view. Will be placed. At this time, the sea-side leg 23a of the second quay crane 20 enters between the sea-side leg 13a and the land-side leg 13b of the first quay crane 10. At this time, as shown in FIG. 2, the quay cranes 10 and 20 are partially orthogonal to the traveling direction Y, that is, when viewed from the rear in the transverse direction X, a part of the legs 13 of the first quay crane 10 and the traveling devices 12b and 12d. However, a part of the leg portion 23 of the second quay crane 20 and the traveling devices 22a and 22c overlap each other.

  By arranging the first track 11 and the second track 21 on which the first quay crane 10 and the second quay crane 20 travel by shifting the distance from the quay 1 or the ship 2, the first quay is provided. The leg portions 13 and 23 of the crane 10 and the second quay crane 20 overlap the traveling devices 12 and 22. As a result, the beam portion 14 and the beam portion 24 can be brought close to each other. Therefore, the booms 15 and 25 of the adjacent first quay crane 10 and the second quay crane 20 are arranged at positions where cargo handling can be performed with respect to the container rows k1 to k4 of the containers k adjacent to the traveling direction Y on the ship 2. can do. Therefore, cargo handling can be performed on each of the container rows k1 to k4 at a time, and the cargo handling work can be greatly shortened.

The quay cranes 10 and 20 of 1st Embodiment which concern on this invention are not restricted to said structure, For example, the 1st track sea side rail 11a, the 1st track land side rail 11b, the 2nd track sea side rail 21a Alternatively, the second track land side rail 21b may be arranged in this order, and the first quay crane 10 may be arranged on the first track 11 and the second quay crane 20 may be arranged on the second track 21. Even with this configuration, the same effects as described above can be obtained. However, since the distance between the second quay crane 20 and the ship 2 is further increased, the boom 25 of the second quay crane 20 needs to be further lengthened.

  In addition, for example, a branch track may be provided so that the first quay crane 10 and the second quay crane 20 can travel between the first track 11 and the second track 21. According to this structure, arrangement | positioning of the 1st quay crane 10 and the 2nd quay crane 20 can be variously changed with a cargo.

  In conventional quay cranes, a transport cart is made to enter the area between the sea-side leg and the land-side leg to deliver the container. However, in the quay cranes 10 and 20 having the above-described configuration, the transfer of the container k by causing the transport carriage 31 to enter between the sea side legs 13a and 23a and the land side legs 13b and 23b Since 10 and 20 are close to each other, work efficiency is deteriorated.

  Therefore, as shown in FIG. 1, a quay delivery area 40 is provided in which the quay cranes 10 and 20 deliver the container k to the transport cart 31 in an area between the ship 2 and the first track seaside rail 11 a. By delivering the container k to the transport carriage 31 in the quayside delivery area 40, the cargo can be efficiently handled. In addition, by providing the quay delivery area 40, the distance by which the container k is moved by the trolleys 16 and 26 when loading the ship 2 can be shortened. Furthermore, since it is not necessary to pass the container k between the leg parts 13 and 23, cargo handling operation can also be made easy.

  In the quay delivery area 40, a circumferential circuit 32 on which the transport carriage 31 travels is laid. When two or more circumferential circuits 32 are installed in the quayside delivery area 40, two or more transport carts 31 can travel in parallel, so that the efficiency of the container k delivery work is increased.

  As shown in FIG. 3, the container terminal 30 also includes a peripheral circuit 32 that is a travel route of the transport carriage 31, a reciprocating path 33, a storage lane 35 that arranges the container k at a predetermined position, and a yard crane 36 that handles the container. The foreign chassis 37 for transporting the transport cart 31 and the container k to the outside of the container terminal 30 is running.

  Here, as an example, six first quay cranes 10 and five second quay cranes 20 are provided for one ship 2, but the first quay crane 10 and the second quay crane 10 provided for one ship 2 are provided. The number of quay cranes 20 is not limited to this, and any number may be provided.

  The transport carriage 31 circulates around the circumference circuit 32 in an annular shape, travels on a round trip path 33, and transports the container k to the storage lane 35. The conveyance carriage 31 is formed of an unmanned conveyance carriage (hereinafter referred to as AGV). The transport carriage 31 is not limited to AGV but may be manned, but AGV is suitable from the viewpoint of efficiency. The circumferential circuit 32 circulates all the first quay cranes 10 and the second quay cranes 20 in an annular shape, and is laid in the quay apron region so as to pass through the quay delivery region 40. The peripheral circuit 32 and the reciprocating path 33 are formed by embedding a magnetic tape or the like, and the transport carriage 31 detects the magnetic tape with a sensor so that the traveling direction can be selected without departing from the path or by branching or crossing. Even in such a case, the traveling direction can be controlled.

  Next, the operation of the quay cranes 10 and 20 and the container terminal 30 including them according to the first embodiment of the present invention will be described. As shown in FIG. 3, the quay cranes 10 and 20 load and unload the container row of containers k arranged in the traveling direction Y of the quay cranes 10 and 20 on the ship 2. The quay cranes 10 and 20 deliver the container k to the conveyance carriage 31 in the quay delivery area 40, and the conveyance carriage 31 that has received the container k circulates around the circumference circuit 32 in an annular manner, travels on the round trip path 33, and Transport to storage lane 35. Further, the vehicle travels in the round trip path 33 and the circumferential circuit 32, stops at the quay cranes 10 and 20 that receive the container k, and receives the container k.

  According to said operation | movement, the quay cranes 10 and 20 can carry out the cargo handling with respect to the row | line | column of the container k adjacent to the traveling direction Y of the quay cranes 10 and 20 on the ship 2, and the cargo handling container k is quay delivery area | region. It can be delivered to the transport cart 31 by 40 and transported to the storage lane 35 using the transport cart 31. Cargo handling efficiency can be improved by providing an area between the quay 1 and the first track 11 while handling an adjacent container k and delivering the container k to the transport carriage 31.

  As shown in FIG. 4, the quay cranes 10 and 20 according to the second embodiment of the present invention are provided with a bridge-like gantry 50 below the quay cranes 10 and 20. The bridge-like mount 50 includes a plurality of piers 51 and a bridge girder 52 on which the first track 11 and the second track 21 are laid, and an opening 53 through which the transport carriage 31 can pass between the piers 51. The bridge-like pedestal 50 is formed in a bridge shape with reinforcing bars or the like, and supports a bridge girder 52 on which the first track 11 and the second track 21 are laid by a plurality of piers 51.

  The 1st quay crane 10 and the 2nd quay crane 20 are provided so that it can drive | work on the 1st track | truck 11 and the 2nd track | truck 21 laid in the bridge girder 52 of said bridge-like mount frame 50. FIG. Each opening 53 is provided with a short-circuit path 34 that is a travel path of the transport carriage 31. As shown in FIG. 5, the transport cart 31 can pass under the bridge-like mount 50 and go back and forth between the quay delivery area 40 and the area where the storage lane 35 is installed.

  According to this configuration, the transport carriage 31 can pass through the opening 53 of the bridge-like mount 50, and it is not necessary to go around all the quay cranes 10 and 20 one by one, and the travel distance of the transport carriage 31 is shortened. Can do. In addition, since the travel distance of the transport cart 31 is shortened, the number of transport carts 31 can be reduced and the cost can be reduced.

  In addition to the above-described configuration, the bridge-like gantry 50 may be formed with the pier 51 and the bridge girder 52 in a wall shape and the opening 53 in a tunnel shape.

  Next, as shown in FIG. 6, operation | movement of the container terminal 30 provided with the quay cranes 10 and 20 of 2nd Embodiment which concerns on this invention is demonstrated.

  The first quay crane 10 and the second quay crane 20 traveling on the first track 11 and the second track 21 on the bridge-like mount 50 load and unload the container k from the ship 2. The container k is delivered to the transport cart 31 in the quay delivery area 40. The transport cart 31 that has received the container k travels in the order of the peripheral circuit 32 and the round-trip path 33 and transports the container k to the storage lane 35. When the container k is transferred to the yard crane 36 disposed in the storage lane 35, the transport carriage 31 is controlled to return to the nearest first quay crane 10 or the second quay crane 20, and the opening 53 of the bridge-like gantry 50 is controlled. It travels on the short circuit 34 laid so that it may pass, and it returns to the quay delivery area 40. Then, the container k is transported again.

  When the container k is loaded onto the ship 2, the container k is transported from the storage lane 35 to the first quay crane 10 and the second quay crane 20 through the round trip path 33 and the circumferential circuit 32. The transport carriage 31 that has passed the container k travels on the nearest short-circuit path 34 and returns to the storage lane 35.

  With the above operation, the travel distance of the transport carriage 31 can be shortened, and the working time for cargo handling can be shortened. Therefore, cargo handling efficiency can be improved. Further, since the distance traveled by the transport cart 31 can be reduced, the number of transport carts 31 can be reduced and the maintenance cost can be reduced.

  As shown in FIG. 7, the container terminal 30 according to the third embodiment of the present invention is configured such that the peripheral circuit 32 configured as described above is not annular, but includes a quay delivery area 40, a bridge-like frame 50, a storage lane 35, and the like. Each of them is formed with a straight line along the quay. Then, the transport carriage 31 can be switched back, and two short-circuit paths 34 are laid in the opening 53 of the bridge-like mount 50 so that the transport carriage 31 can pass through the opening 53. According to this structure, the conveyance trolley | bogie 31 can be made to drive | work in a substantially straight line, and can raise efficiency further.

  A quay crane 60 according to a fourth embodiment of the present invention includes a girder 61 and a traveling device 62 as shown in FIG. Then, the traveling device 62 is formed so as to be able to travel on a track (not shown) laid on the upper portion of the bridge-like mount 70. The girder 61 includes a boom (not shown), a trolley (not shown) that can move the boom, and a lifting tool 63. The bridge-like gantry 70 includes a plurality of piers 71, a bridge girder 72, and an opening 73 through which the transport carriage 31 can pass.

  According to this configuration, the bridge-like gantry 70 is provided instead of the legs of the conventional quay crane, and the girder portion 61 having the boom travels on the bridge-like gantry 70 by the traveling device 62, and the adjacent girder portions 61 are arranged. Since they can be brought close to each other, the girder 61 can unload the container k adjacent to the traveling direction Y of the quay crane 60 on the ship 2 and can increase the loading efficiency. Further, when the container k adjacent in the traveling direction Y is unloaded, the adjacent quay cranes 60 do not overlap each other. Furthermore, since the transport carriage 31 can pass through the opening 73 of the bridge-like mount 70, it is possible to freely enter and exit the quay delivery area 40 for delivering the container k to the transport carriage 31, and to reduce the travel distance. Can do.

  As shown in FIG. 9, the quay crane 80 according to the fifth embodiment of the present invention has a lateral width L of 40 feet including the traveling device 82 of the quay crane 80 in a rear view in the transverse direction X of the quay crane 80. Is formed within. According to this structure, since each girder part 84 of each adjacent quay crane 80 can be made to adjoin so that the container k adjacent to the traveling direction Y of the quay crane 80 on the ship 2 can be loaded, cargo handling efficiency is raised. be able to. Since only one track is required and a conventional track is used, there is no installation cost. On the other hand, since the lateral width L of the quay crane 80 is thin, attention must be paid to safety. For example, the adjacent quay cranes 80 may be joined to each other with a support or the like, or the adjacent quay cranes 80 may be reinforced so as not to interfere. Further, as described above, the bridge mount 50 may be provided below the traveling device 82.

  The container terminal of the present invention can unload containers adjacent to the traveling direction of a quay crane on a ship when unloading containers, and can also increase the container transport efficiency of the transport carriage. Therefore, it can be provided on a quay or the like and used as a base for marine transportation and land transportation.
