Description

  The present invention can effectively use the site of the container yard of the container terminal and transports the container in each facility in the container yard, particularly in the container yard, in which the interference of the chassis and the cargo handling machine traveling in the container yard is reduced. The present invention relates to an arrangement structure of equipment such as a running track of a chassis.

  The container terminal is a facility that serves as a point of contact between different means of transportation between sea and land. Its main function is to load and unload containers between these different means of transportation. For this reason, a container yard for temporarily storing containers waiting for loading and unloading is provided. In other words, the container yard stores containers that are loaded into or unloaded from a container ship berthed at the quay and loaded into or from a chassis for land transportation. .

  By the way, in order to rationalize container handling work for loading and unloading of containers in a container yard, a labor saving or unmanned operation system has been developed in a container terminal. This can be done by loading containers onto the container ship, loading and unloading containers from the container ship, transporting the container to the storage position by traveling inside the container yard, or transferring the container at the storage position to the container Containers can be transported to the chassis of a ship or land transport by loading a container at the storage position on the chassis, and a yard crane for loading and unloading containers from the chassis can be operated automatically or remotely. It is a system that tries to unmanned the yard.

  In order to promote such labor-saving and unmanned operations, automation of container yard operation plans, etc., and to improve efficiency, a container terminal system has been proposed that prevents the entry of external vehicles into the container yard ( Patent Document 1). This container terminal system includes a container crane that handles containers on a ship, and a container yard that can store and store containers. The container terminal system handles containers between ships and land transport vehicles. A plurality of transfer cranes that have a gate-shaped mainframe and can be loaded or unloaded automatically or manually, and between the container crane and the transfer crane, and a flat container in the container yard The AGV is installed in the vicinity of the boundary between the container yard and the outside, and the container is transferred manually or partially automatically between the AGV in the container yard and the outside land transport vehicle. Perform delivery crane and container In which de and land transport vehicle is configured to include a boundary indicia provided on the boundary between the drivable externally.

  On the other hand, although the container terminal is a facility provided on a vast site, it is required to make effective use of the site area. For example, Patent Document 2 eliminates the need to provide a container three-dimensional storage building to reduce costs. At the same time, a container terminal has been proposed in which space use efficiency is improved without bending the track of the transport carriage. This container terminal has a container yard in which containers are stacked in multiple stages, a container crane capable of loading and unloading containers on a container ship, a container crane that can move along a sea-side traveling rail and a sea-side traverse rail. Containers are transferred between the sea-side transport cart that can deliver containers to and from the land, the land-side transport cart that can move along the land-side traveling rail and the land-side traverse rail, and the land-side transport cart and chassis A transfer machine, a gate-type transfer crane capable of transferring containers between the sea-side transport cart and the land-side transport cart and stacking containers in a plurality of stages between the yard traverse rails, and It has been done.

Patent No. 2892606 JP 11-079409

  When unmanned in the container yard, an automated guided vehicle (AGV) travels as a premise chassis in the container yard to transport the container, and there is no hindrance to the unmanned transport cart. Thus, as disclosed in Patent Document 1, it is necessary to prevent workers and the like from entering the container yard as well as the external chassis. Further, it is necessary that the automatic guided vehicle and the traveling path of the yard crane are separated from each other so that the automatic guided vehicle does not inadvertently enter the traveling path of the yard crane that travels in the container yard.

  When a container terminal is newly established, it is possible to have a structure in which the traveling path is separated from the original plan. However, if an unmanned system is to be introduced into an existing container terminal, the separation cost may increase if the travel paths are separated. Interference between the automatic guided vehicle and the yard crane is avoided. For this reason, in the container terminal which introduced the unmanned system in the existing facility, there exists a possibility that space efficiency may fall.

  Therefore, even if this invention is a new construction or a case where an unmanned system is introduced to an existing container terminal, it is possible to improve space efficiency at a low cost, and a premises crane and a yard crane made up of unmanned transport carts, etc. It is an object of the present invention to provide an arrangement structure of equipment in a container yard that can avoid interference with the device as much as possible.

  As a technical means for achieving the object, the arrangement structure of the equipment in the container yard according to the invention of claim 1 is a traveling route of the premises chassis, and the container is placed between the container ship and the container storage area. In the container yard where the route around the quay to be transported and the route around the delivery area to transport the container between the storage area and the delivery area for loading and unloading to the foreign chassis, the route around the quay and delivery In each travel lane of the route around the area, where the travel lanes are arranged adjacent to each other, the quay route is arranged on the container block side.

  In order to load and unload containers in the storage area of the container yard, the local chassis must be located along the container block, which is guided by a storage lane. This storage lane can be entered and exited from both the quay route and the delivery area route. In addition, when an automated guided vehicle is used for a campus, these routes need to be one-way so as not to interfere with each other. On the other hand, the entrance lane for entering the storage lane and the exit lane for exiting the storage lane are connected to the loading lane along the container ship in the route around the quay, and to the delivery lane in the delivery route, and When leaving the storage lane, the route is arranged so that you can choose either the route around the quay or the route around the transfer area.

  Since the approach lane and the exit lane are each provided with a quay route and a delivery area route, two lanes are provided in parallel. Of these two lanes, the route around the quay is arranged on the container block side. The container terminal is operated on the basis of the schedule of the container ship, and the ship cargo handling that transports the container in relation to the container ship handles the delivery cargo handling that carries the container in relation to the foreign chassis. Priority. Therefore, the route around the quay related to the cargo handling on the ship is the container block side. As a result, when entering the storage lane and leaving the storage lane, the on-site chassis will not cross other travel lanes, and the on-site chassis for the main cargo handling will be given priority. The

  In addition, the equipment arrangement structure in the container yard according to the invention of claim 2 is a traveling route of the premises chassis, the route around the quay for transporting the container between the container ship and the container storage area, and the foreign chassis. In a container yard where a delivery area for loading and unloading and a route around the delivery area for transporting containers between the storage area are arranged on the container block side of the route around the quay and the route around the delivery area A non-storage portion that does not store a container is provided at each corner of the container block that faces the turning portion entering the storage area and the turning portion exiting from the storage area of the route arranged.

  In order to effectively use the space in the container yard, it is preferable to bring the container block and the traveling lane of the premises chassis as close as possible. When the traveling lane is approached, the rear wheel is biased toward the turning center due to the difference between the inner wheels of the premises chassis in the portion that wraps around the container block, so that the premises chassis may come into contact with the container. Therefore, the container is not stored in a position where there is a possibility of contact.

  In addition, the equipment arrangement structure in the container yard according to the invention of claim 3 is a traveling route of the local chassis, the route around the quay for transporting the container between the container ship and the container storage area, and the foreign chassis. In the container yard where the delivery area for loading and unloading and the route around the delivery area for transporting the container between the storage area, there is a difference in the length of the container stored in the container block In addition, the container stored at the end of the container block is the longest, and the loading and unloading machine used for loading and unloading the container with respect to the premises chassis is prevented from protruding to the side of the container. To connect the traveling lane that forms the quay route or the delivery route route to the container block. It is characterized in that arranged by.

  2. Description of the Related Art A cargo handling machine, such as a bridge-shaped yard crane, used for loading and unloading containers on a campus chassis is positioned in a state of straddling the campus chassis and a container block. At this time, if the length of the container is short, the end portion in the length direction of the yard crane may be positioned to protrude from the side wall in the longitudinal direction of the container. For this reason, when a short container is arranged at the end of the container block, when a cargo handling operation is performed on the container, a part of the yard crane protrudes to the side of the container, and the protruding part has a campus chassis. The driving lane cannot be arranged. Therefore, a container having a length that does not protrude a part of the cargo handling machine during the cargo handling operation is arranged at the end of the container block.

  In addition, the facility arrangement structure in the container yard according to the invention of claim 4 is a traveling route of the premises chassis, a route around the quay for transporting the container between the container ship and the container storage area, and an external chassis. In a container yard in which a delivery area for loading and unloading and a delivery area route for transporting containers between the storage area are arranged, either or both of the route around the quay and the route around the delivery area It is characterized by a switchback area that changes the direction of the local chassis.

  Most of the containers loaded on the container ship are arranged with the doors on the stern side. This is because water droplets collide with the container from the bow side during navigation, so that the door body is directed toward the stern side so that the container is not flooded. On the other hand, among the containers, for example, there is a so-called refrigerated container that stores refrigerated cargo. Some of these refrigeration containers are inconvenient if they are submerged in the refrigeration apparatus. Therefore, some refrigeration containers are arranged with the refrigeration apparatus facing the stern side, that is, with the door body facing the bow. That is, the direction in which the door of the container loaded on the container ship faces is not constant. When these containers are loaded on an external chassis, the door body is required to face rearward in order to open and close the door body. Therefore, when transferring containers from the local chassis to the foreign chassis, if the traveling directions of the local chassis and the external chassis are constant, unless the container is stored and the container is specially required It is preferable that the door body faces in a certain direction. The specially required container is a case where a power source is required, such as a refrigerated container, and the container must be stored in a direction corresponding to the position of the power source. Even in a container loaded in a foreign chassis and carried into a container terminal, the direction in the storage area may be restricted.

  That is, the container loaded on the container ship with the door body being in a non-constant direction needs to be directed in a certain direction in the storage area. Or the case where the direction of the carried-in container must be stored as a predetermined direction arises. For this reason, a switchback area is provided, and the direction of the container can be changed by changing the front and rear directions of the premises chassis. This switchback area is preferably arranged at a position where there is no hindrance to the traveling of other premises chassis, for example, a part of the route around the quay and a ship lane arranged in parallel with the quay and a sea-land direction One or both of the intersections with the entrance lane and exit lane arranged in the area, part of the route around the delivery area, and the delivery lane arranged in parallel to the delivery area, and arranged in the sea-land direction Other appropriate positions such as one or both of the intersections with the approach lane and the exit lane can be provided.

  In addition, the facility arrangement structure in the container yard according to the invention of claim 5 is a traveling route of the premises chassis, a route around the quay for transporting the container between the container ship and the container storage area, and an external chassis. In the container yard where a delivery area for loading and unloading and a route around the delivery area for transporting the container between the storage area are loaded and unloaded at the storage area in the storage area The right-angle traveling lane of the cargo handling machine provided to the vehicle is disposed on the opposite side of the container block across the quay route route and the delivery area route route.

  When the yard crane changes the row of container blocks, the yard crane moves in a right-angle traveling lane in a direction perpendicular to the longitudinal direction of the container blocks. For this reason, it may be necessary to cross the lane of the local chassis during this movement. In addition, a yard crane moving on a right-angle lane may become an obstacle to the traveling of the premises chassis. For this reason, a right-angle traveling lane of the yard crane, which is arranged on the end side of the container block row, is arranged outside the traveling lane of the campus chassis.

  The facility arrangement structure in the container yard according to the invention of claim 6 is characterized in that the local chassis is an automatic guided vehicle.

  That is, the on-site chassis may be manned by a driver or unmanned such as AGV. In particular, in the case of an automated guided vehicle, as described above, since each route travels in one way, the opportunity to interfere with a cargo handling machine such as a yard crane increases. For this reason, when an automatic guided vehicle is used, it is effective to adopt this arrangement structure in which the chance of interference is reduced.

  According to the equipment arrangement structure in the container yard according to the first aspect of the invention, the chance that the on-site chassis used for the main cargo handling will interfere with other on-site chassis, yard cranes, etc. is reduced, and the main cargo handling will be given priority. Smooth operation of container terminals can be achieved.

  Moreover, according to the arrangement structure of the equipment in the container yard according to the invention of claim 2, since the traveling lane of the premises chassis can be arranged as close to the container block as possible, the space efficiency of the container yard can be increased and more Containers can be stored.

  Moreover, according to the arrangement structure of the equipment in the container yard according to the invention of claim 3, a part of the yard crane does not protrude to the side of the container block during the cargo handling work in which the container is suspended by the yard crane. For this reason, the traveling lane can be arranged as close as possible to the end of the row of container blocks, and the storage space for the container can be widened.

  Moreover, according to the arrangement structure of equipment in the container yard according to the invention of claim 4, in any direction of the container loaded on the container ship, in the container yard, it can be in a predetermined direction, The direction of the door of the container handed over to the foreign chassis can be the rear side of the foreign chassis.

  Further, according to the arrangement structure of equipment in the container yard according to the invention of claim 5, even if the yard crane is traveling in a right-angle traveling lane, it does not hinder the traveling of the premises chassis, and cargo handling work in the container or yard The efficiency is not impaired.

  Moreover, according to the arrangement structure of the equipment in the container yard according to the sixth aspect of the invention, it is possible to promote labor saving and unmanned container terminals.

  Hereinafter, based on the illustrated preferred embodiment, a facility arrangement structure in a container yard according to the present invention will be specifically described.

  FIG. 3 is a schematic plan view showing an example of a container terminal provided with a container yard according to the equipment arrangement structure according to the present invention. The container ship 2 is moored to the quay 3 and the container 5 is loaded and unloaded by the quay crane 4. The quay 3 is arranged at the edge of the container yard 6, and the containers 5 loaded and unloaded on the container ship 2 are stored and stored in the storage area 6 a of the container yard 6. An appropriate number of containers 5 are stacked in a matrix to form a container block 5a, and an appropriate number of container blocks 5a are arranged in a matrix in the storage area 6a. For the description of the present embodiment, B to H are given to the rows of the container blocks 5a in order from the land side. In order to move the container 5 in the storage area 6a, a dedicated local chassis 7a is used, and an external chassis 7b is used for land transportation between the container terminal 1 and the shipper. An automatic guided vehicle (AGV) is used for the local chassis 7a. A yard crane 8 is used for loading and unloading the container 5 on the on-site chassis 7a. The yard crane 8 shown in FIG. 3 is a bridge crane, and as shown in FIG. 4, the container 5 is loaded so as to straddle the container block 5a and the premises chassis 7a stopped to the side of the container block 5a. , Do loading and unloading. The yard crane 8 moves in the traveling direction along the container block 5a, between the container block 5a and the container block 5a to move to the adjacent container block 5a, and in the rows B to H of the container block 5a. A right-angled movement along a right-angle traveling lane 61 provided on the side can be performed.

  The foreign chassis 7b enters the container terminal 1 from the entrance gate Gi and exits from the exit gate Go or the sub-gate Gs. This is because the foreign chassis 7b in which the actual container 5 containing the imported cargo is loaded needs to be carried out after the bonded process is performed at the exit gate Go, and the foreign chassis 5 in which the empty container 5 is loaded. 7b or an empty foreign chassis 7b in which the container 5 is not loaded does not need to perform a bonded procedure, and is thus retreated from the sub-gate Gs. On the side of the entrance gate Gi, buildings such as a management building 9, a guardman stuffing station 10, and an office building 11 are arranged. In addition, an empty van pool 12, a repair shop 13, and a water washing place 14 in which empty containers 5 are stored are arranged on the opposite side of the management building 9 across the entrance gate Gi. The installation status of these gates G and the respective facilities around the gates G are not limited to these, and the installation status and required facilities of the gates G differ depending on the container yard operation system. Of course.

  A fence is provided at a position that secures an area where the foreign chassis 7b that has entered from the gate G can move sufficiently and sufficiently so that the foreign chassis 7b cannot enter the storage area 6a of the container yard 6 in which the local chassis 7a is traveling. 20 is installed. The local chassis 7a is used for cargo handling work on the container 5 in the storage area 6a on the sea side, that is, on the inner side of the fence 20, and the foreign chassis 7b is used on the gate G side of the fence 20, that is, on the outer delivery area 6b. 5 is used for loading and unloading. A switching area 21 is provided for transshipment of the container 5 between the local chassis 7a and the foreign chassis 7b with the fence 20 in between. A fence gate 20 a that can be opened and closed is provided at an appropriate position such as an end of the fence 20.

  The switching area 21 from the left end to the appropriate range in FIG. 3 is a carry-in area 21 i so that the foreign chassis 7 b can temporarily place the container 5 that has been carried for carrying it into the container yard 6. . Further, the carry-out area 21o extends from the end of the carry-in area 21i to the right end. The positional relationship between the carry-in area 21i and the carry-out area 21o is such that the carry-in area 21i is located on the front side in the traveling direction of the local chassis 7a, and the carry-out area 21o is located on the rear side. For this reason, the local chassis 7a that unloads the containers 5 in the unloading area 21o can load the containers 5 loaded in the loading area 21i. In addition, the buffer zone part 22 is provided between the carrying-in area 21i and the carrying-out area 21o, and these areas 21i and 21o are divided. The buffer band portion 22 is provided so that the boundary between the carry-in area 21i and the carry-out area 21o can be clarified, and is not necessarily provided if the section between these areas 21i and 21o is clear. Further, by providing this buffer band portion 22, when the number of containers 5 in the carry-out area 2 and the carry-out area 210 increases or decreases, both the carry-out container 5 and the carry-in container 5 are connected to the buffer band portion. 22 can be temporarily placed, and the storage area of the container 5 can be changed easily. When the storage area is changed, the position of the buffer band 22 is also changed.

  Further, at both ends of the fence 20, a circular fence 25 is provided that extends toward the storage area 6 a of the container yard 6 and is arranged along the quay 3, and the outer side of the circular fence 25 is connected to the external chassis 7 b. A manned chassis driven by a driver such as a manned premises chassis 7a can run. For this reason, the container 5 can be directly loaded onto the container ship 2 from the foreign chassis 7b, or the container 5 can be loaded directly onto the foreign chassis 7b from the container ship 2 to cope with an emergency or the like. At this time, the quay crane 4 is used for loading and unloading the containers 5.

  A delivery crane 23 is arranged in the switching area 21, and the container 5 is loaded into and unloaded from the switching area 21. The delivery crane 23 is preferably the same as the yard crane 8 disposed in the container yard 6. FIG. 4 shows the front of a tire-type bridge-shaped yard crane 8 used for cargo handling work in the container yard 6. The tire-type bridge-shaped yard crane 8 includes two pairs of left and right legs 8b having tires 8a at the lower part, that is, four legs 8b, and a pair of upper and lower legs 8b. No. 8c is spanned in parallel. Guided by the pair of girders 8c, the trolley 8d is movable in the transverse direction, which is the left-right direction in FIG. 4, and the block 5a of the stacked container 5 and the on-site chassis 7a stopped on one side of the block 5a. , The container 5 is loaded onto or unloaded from the chassis 7 by being suspended by the trolley 8d. The container 5 is held and lifted by a spreader 8e that is moved up and down by a trolley 8d. In addition, the cab 8f on which the operator is boarded moves together with the trolley 8d, and the operator operates the trolley 8d. When the yard crane 8 is set to unmanned operation, the operator does not get on the vehicle and is operated by automatic operation or remote operation.

  As described above, the yard crane 8 moves in the direction along the container block 5a in a state of straddling the container block 5a, that is, in the traveling direction that is the direction penetrating the paper surface in FIG. 4, and from one container block 5a. In order to move to another adjacent container block 5a, it is possible to move in a direction along the right-angled traveling lane 61, that is, a right-and-left direction in FIG. For this reason, the rotation axis of the tire 8a is rotatable about an axis in the vertical direction, and the direction of movement can be changed by changing the direction of the rotation axis.

  FIG. 1 shows the container yard 6 shown in FIG. 3, and shows the traveling path of the local chassis 7a traveling in the storage area 6a. The on-site chassis 7a has the container 5 between the container ship 2 and the storage area 6a (the travel trajectory between them is referred to as a “quake route”), and between the storage area 6a and the switching area 21 (the travel trajectory therebetween). Is referred to as a “route around the delivery area”). In order to load and unload the containers 5 in the storage area 6a, the storage lanes 31 arranged between the B to H rows of the respective container blocks 5a are traveled to the storage position. For this reason, the storage lane 31 is common to the quay route and the delivery area route. The wharf route includes the loading lane 26 arranged along the quay 3 and the B to H rows of the container blocks 5a, the approach lane 27 along the sea-land direction passing through the left side in FIG. 1, and the sea-land direction passing through the right side as well. And exit lane 28 along the line. Further, the route around the transfer area is the same as the transfer lane 32 arranged along the switching area 21 and the approach lane 33 along the sea-land direction passing through the left side in FIG. It consists of an exit lane 34 along the sea-land direction passing through the right side. The storage lane 31 is connected to each of the entry lanes 27 and 33 and each of the exit lanes 28 and 34. Further, in this embodiment, two delivery lanes 32 are provided, and when the transfer work of the container 5 is performed in one delivery lane 32, the other delivery lanes 32 can travel. It is.

  In this embodiment, since the container ship 2 is on the port side, the premises chassis 7a travels in one way from the right side to the left side in FIG. In the delivery lane 32, the local chassis 7a travels in one-way from the right side to the left side in FIG. For this reason, on the quay route, the premises chassis 7 a can return from the loading lane 26 to the loading lane 26 through the approach lane 27, the storage lane 31, and the exit lane 28. In the route around the transfer area, the local chassis 7 a can return from the transfer lane 32 to the transfer lane 32 through the approach lane 33, the storage lane 31, and the exit lane 34. Further, the local chassis 7 a that has traveled in the storage lane 31 can proceed to either the exit lane 28 or the exit lane 34. Therefore, for example, the local chassis 7a that has entered the storage lane 31 from the route around the quay can proceed to the route 32 around the delivery area. The approach lanes 27 and 33 and the exit lanes 28 and 33 along the sea-land direction are all arranged with the lanes 27 and 28 of the route around the quay close to the container block 5a. For this reason, when the local chassis traveling on the quay route enters the storage lane 31 and leaves the storage lane 31, it does not cross other travel lanes.

  As shown in FIGS. 1 and 2, the corner of the container block 5 a is a part where the local chassis 7 a turns when going from the entry lane 27 to the storage lane 31, and from the storage lane 31 to the exit lane 28. As shown by an imaginary line in FIG. 2, a non-storage part 5b that does not store the container 5 is provided at a part facing each of the parts where the local chassis 7a turns when traveling. In addition, there are several kinds of dimensions of the container 5 handled in the container terminal 1 having different lengths in the longitudinal direction, and the longest container 5 is stored at the end of the container block 5a. For example, the container 5 has a length of 20 feet and 40 feet, and the container terminal 1 that handles them has a 40-foot container 5 stored at the end of the container block 5a. This is because when a 20-foot container 5 is unloaded with the yard crane 8, a part of the yard crane 8 protrudes to the side of the end of the container 5, and the protruding chassis 7a This is because the approach lane 27 and the exit lane 28 cannot be arranged, and the lanes 27 and 28 cannot be sufficiently brought close to the container block 5a.

  Further, the right-angle traveling lane 61 arranged along the ends of the rows B to H of the container block 5a has a container block sandwiching the entry lane 27 and the exit lane 33 as shown in FIG. It is arranged on the opposite side of 5a and on the opposite side of container block 5a across exit lane 28 and entry lane 34, that is, the outermost positions.

  Further, in the container yard 6, the door body needs to be directed in the same direction as the other containers 5, and for this purpose, a switchback area 37 for exchanging the front and rear of the local chassis 7a is provided. The switchback area 37 is provided at both the branching portion of the loading lane 26 and the approach lane 27 or the leaving lane 28, and the loading lane 26 is further arranged than the branching portion between the entering lane 26 and the leaving lane 28. An extended reversal area 37a is provided. From the loading lane 26, it is possible to proceed to either the inversion area 37a or the approach lane 27, and to proceed to the entry lane 27 from the inversion area 37a. Further, the exit lane 28 can proceed to either the loading lane 26 or the reversing area 37a, and the reversing area 37a can proceed to the loading lane 26. Note that the switchback area 37 may be provided at another position as long as it does not interfere with the local chassis 7a. Further, if necessary, a switchback area may be provided in a part of the delivery route. In that case, for example, the direction of the container 5 carried in can be reversed.

  Further, as shown in FIG. 1, a standby queue area 21a in which the foreign chassis 7b can be arranged and arranged is provided on the switching area 21 on the side of the delivery area 6b to receive the container 5. The foreign chassis 7b installed in the container terminal 1 is arranged in the waiting line area 21a.

  As the delivery crane 23, a bridge-type crane is used as shown in FIG. 3, and the same one as the yard crane 8 described above is preferable. The transfer crane 23 transfers the container 5 between the local chassis 7a and the foreign chassis 7b.

  The effect | action of the arrangement structure of the installation in the container yard of this invention comprised by the above is demonstrated below.

  When loading / unloading the container 5 to / from the container ship 2, the premises chassis 7a travels on the loading lane 26 and stops at a predetermined position where the container 5 should be loaded or unloaded. The container 5 is loaded or unloaded by the crane 4. As shown in FIG. 3, when the container ship 2 is on the port side, the premises chassis 7a travels from the right to the left in FIGS. The on-site chassis 7a loaded with the container 5 enters the entry lane 27 from the loading lane 26 and proceeds to a storage lane 31 having a specified storage position in which the container 5 is to be stored. When entering the storage lane 31 from the approach lane 27, the local chassis 7a turns as shown in FIG. During this turning, the premises chassis 7a passes through the position approaching the container block 5a due to the inner ring difference, but the non-storage part 5b is provided in the part facing the turning part and the container 5 is not stored. The local chassis 7a can be swung by projecting to the non-storage position 5b by the inner ring difference. Therefore, the approach lane 27 and the storage lane 31 can be arranged as close as possible to the container block 5a, and the storage area 6b of the container 5 can be expanded.

  When the frozen container 5 loaded on the container ship 2 is transported to the storage position, the direction of the door of the frozen container 5 when loaded on the container ship 2 is the direction of the door of the other container 5. It may be the opposite direction. When the premises chassis 7a travels on the loading lane 26, it travels in a direction that matches the direction of the door body of the other container 5. Therefore, when the refrigeration container 5 is loaded on the premises chassis 7a, the door body moves to the premises chassis 7a. It will face the direction of travel of 7a. When the refrigerated container 5 is stored in the storage area 6a in this state, the direction of the door body is opposite to that of the other containers 5, and when the delivery area 6b is handed over to the foreign chassis 7b, the door body is placed in front of the foreign chassis 7b. Will be inconvenient. Therefore, the front and rear of the local chassis 7a are switched using the switching area 37. That is, the local chassis 7 a to which the refrigerated container 5 is transferred from the container ship 2 proceeds to the entry lane 27 via the inversion area 37 a of the switching area 37 when proceeding to the entry lane 27. As a result, the front and rear of the local chassis 7a are interchanged, and the rear side up to that point travels forward, so the door of the refrigerated container 5 has the same orientation as the other containers 5 and is stored in the storage area 6a. In this state, the direction of the door body can be aligned in the same direction as the other containers 5. Therefore, in a state where the door body is loaded on the external chassis 7b, the door body faces rearward, and there is no problem in opening and closing the door body. For example, as in the case of securing the power supply of the refrigerated container 5, the container 5 that needs to be stored in the storage area 6a in the opposite direction to the other containers 5 is transported without inverting the local chassis 7a. .

  On the other hand, when the refrigerated container 5 stored in the storage position is transported to the container ship 2, it passes through the reversal area 37 a of the switchback area 37 when proceeding from the exit lane 28 to the load lane 26. That is, by entering the reversal area 37a from the exit lane 28 and proceeding to the loading lane 26, the front and rear of the premises chassis 7a are interchanged, so that the direction of the door of the refrigerated container 5 can be reversed with respect to the other containers 5. When loaded on the container ship 2, the refrigeration apparatus is prevented from splashing seawater.

  When the yard crane 8 changes the row of the container blocks 5a or performs block replacement, the yard crane 8 travels on the right-angle traveling lane 61. For example, when the yard crane 8 performing the cargo handling work in the row H moves to the row G, the vehicle travels on the right-angle traveling lane 61. At this time, if the yard crane 8 is moved to the right-angle traveling lane 61 where the container block 5a is not stored, the rotation axis of the tire 8a is rotated by approximately 90 ° about the vertical axis, and the tire 8a Change the orientation of. As a result, the yard crane 8 can travel at a right angle and travels on the right-angle traveling lane 61 to change blocks. When traveling in the right-angle traveling lane 61 located on the side of the container block 5a during this right-angle traveling, the right-angle traveling lane 61 is located outside the entrance lanes 27, 33 and the exit lanes 28, 34. Therefore, the yard crane 8 crosses the entry lanes 27 and 33 or the exit lanes 28 and 34 until the yard crane 8 reaches the right-angle traveling lane 61. However, while reaching the right-angle traveling lane 61 and traveling in the right-angle traveling lane 61, there is no obstacle to the on-site chassis 7a traveling on the approach lanes 27, 33 and the exit lanes 28, 34. In addition, when the yard crane 8 crosses the approach lanes 27 and 33 or the exit lanes 28 and 34, it controls to stop the campus chassis 7a.

  Further, when the yard crane 8 loads or unloads the container 5 stored at the end of the container block 5a or unloads the container 5 at the storage position, the yard crane 8 is positioned at a position straddling the end of the container block 5a. However, the container 5 disposed at the end is the longest container 5 to be handled at the container terminal 1. For this reason, even if the yard crane 8 is located across the container 5, a part of the yard crane 8 does not protrude from the side of the container 5. Therefore, the approach lane 27 of the route around the quay can be made sufficiently close to the container block 5a.

  The arrangement structure of various facilities such as the arrangement of container blocks and storage lanes in the container terminal described above is an example, and there are various arrangements depending on the container terminal. The facility arrangement structure according to the present invention is implemented in accordance with the arrangement of the storage lanes, the arrangement of the storage lanes, and the like.

  According to the arrangement structure of equipment in the container yard according to the present invention, the traveling lane of the local chassis is provided as close as possible to the container block, and interference between the local chassis and the yard crane is avoided as much as possible. For this reason, the fall of the space efficiency when introducing an unmanned operation system in the existing container terminal can be suppressed as much as possible. Therefore, it can contribute to promotion of introduction of an unmanned operation system to existing facilities.
