JP 2000-44063 A

  The present invention has been made in view of the above-described problems, and the problem is that a container terminal and a portal crane that improve the cargo handling efficiency while ensuring safety during movement of the portal crane and the transport vehicle. And providing a container terminal operation method.

  The container terminal of the present invention for solving the above-described problems includes a storage lane in which a large number of containers are stored, and a conveyance path that extends along the storage lane adjacent to one direction of the storage lane. And a portal crane having a girder that extends from one direction side to the other direction of the storage lane across the transportation path, with one end in the extending direction of the transportation path as an inlet and the other end as an outlet. In the container terminal where the transport vehicle for transporting the container travels along the transport path and the portal crane moves along the storage lane, the storage is located at a midway position in the extending direction of the transport path. The lane is a configuration in which the approach path and the exit path of the transport vehicle are connected to the side surface facing each other.

  According to this structure, the portal crane currently moving to a transport vehicle can be detoured by connecting the approach path and the exit path to the transport path straddling the portal crane. As a result, when carrying out and carrying in the container, the portal crane is allowed to wait for the transport vehicle to wait until the movement of the portal crane is completed, or until the transport vehicle passes through the transport path. It is possible to reduce the waiting of the movement. Therefore, it is possible to prevent the transport vehicle from passing under the girder of the moving gate crane and to ensure safety, and to improve the handling efficiency by smoothly moving the transport vehicle and the portal crane. .

  In the container terminal, the transport vehicle travels in the order of the approach path and the transport path, and bypasses a section between the entrance of the transport path and the entrance to the transport path from the entrance path. One of the travel routes that travels in the order of the travel route, the transport route, and the exit route and bypasses the section between the exit route from the transport route to the exit route and the exit of the transport route. It is desirable to have a configuration that travels along a route.

  According to this configuration, when loading and unloading containers on the entrance side of the storage lane transport path, when transporting the container on the exit side of the storage lane transport path, the transport vehicle travels on the exit detour path. Causes the transport vehicle to travel along the detour route. Thereby, the distance which a conveyance vehicle drive | works a conveyance path can be shortened, and the situation which passes under the moving portal crane can be reduced. It is also possible to run a plurality of transport vehicles on the transport path at a time.

  In addition, in the portal crane, the entrance of the transport path and the entrance to the transport path from the approach path are provided with opening / closing means, and the opening / closing means of the entrance is connected to the entrance of the transport path. In the section between the entrance and exit, the entrance is closed while the portal crane is moving, and the entrance is opened while the portal crane is not moving, and the entrance opening and closing means However, in the section between the exit path from the transport path to the exit path of the transport path and the exit, the entrance is closed while the portal crane is moving, and the portal crane is It is desirable that the entrance is opened while not moving.

  According to this configuration, when the transport vehicle travels on the transport path and passes under the girder of the portal crane, entry of the transport vehicle into the transport path can be prohibited. Therefore, safety can be further improved. For example, when a container is loaded / unloaded on the entrance side of the transport path of the storage lane, the entrance is closed while the portal crane is moving in the section between the transport path entrance and the entrance. On the other hand, when loading and unloading containers on the exit side of the transport path of the storage lane, the entrance is closed while the portal crane is moving in the section between the exit and the exit. Thereby, it can avoid that a transport vehicle passes under the moving portal crane, and can ensure the safety at the time of movement of a portal crane and a transport vehicle, and can improve cargo handling efficiency.

  Further, the container terminal preferably includes a control device for remotely operating the portal crane, and the control device controls the opening / closing means based on the remote operation of the portal crane. According to this configuration, the opening / closing means can be controlled in conjunction with the remote operation of the portal crane, and control complexity is avoided.

  In addition, in the container terminal, the loading of the container between the transported vehicle and the storage lane is stopped on the transported vehicle below the girder of the portal crane that has stopped moving. It is desirable to provide travel restarting means for restarting travel based on the wholesale status and the movement status of the portal crane on the travel route of the transported vehicle.

  The travel restart means here refers to transporting the transport vehicle driver to the transport vehicle driver by means of an indicator that displays a signal to the transport vehicle driver to resume travel or a circuit breaker that opens and closes the storage path. This means a means for resuming driving.

  According to this configuration, according to the loading / unloading status of the container and the moving status of the portal crane, the traveling of the transport vehicle can be resumed after the safety when traveling is confirmed, and the transport vehicle can be operated more safely. It can be run.

And the portal crane of this invention for solving said subject is the portal crane arrange | positioned at the container terminal as described above, It is extended below from the both ends of the said girder which the trolley moves, and the said girder A leg device that travels in a direction perpendicular to the extending direction of the girder at the lower end, and the leg adjacent to the transport path is the lower end of the leg body. It is the structure which has a display apparatus which displays the signal of the restart of driving | running | working of the said transport vehicle in a part.

  In the portal crane, it is preferable that the leg adjacent to the transport vehicle traveling on the transport path includes an opening / closing device that opens and closes the transport path at a lower end portion of the leg.

  According to the above-mentioned portal crane, by providing the above-mentioned traveling resumption means in the portal crane, it is possible to improve the cargo handling efficiency while ensuring the safety when the portal crane and the transport vehicle are moved. . In addition, since the position where the transport vehicle stops on the transport path is below the girder of the portal crane, the cost can be reduced by providing the portal crane rather than installing a plurality of travel restarting means on the ground.

  And the operation method of the container terminal of this invention for solving said subject is extended along the storage lane adjacent to the storage lane where many containers were stored, and the one direction side of the storage lane. A crane that has a girder that extends from one side of the storage lane to the other side across the transport path. In the container terminal operating method, the container crane is moved along the storage lane to load and unload containers between the transport vehicle and the storage lane, and the portal crane moves on the travel route of the transport vehicle. If the vehicle is not running, the vehicle is allowed to travel under the portal crane that is not moving by traveling the transportation route, and the portal crane is moving on the traveling route of the vehicle. In this case, a method characterized by diverting the gantry crane moving by running an exit path from the entry path and the transport path to the transport path to the truck.

  In the container terminal operation method described above, if the portal crane is moving on the travel route of the transport vehicle and the mobile crane cannot be detoured, the transport vehicle It is desirable to wait at the entrance to the transport path and the entrance to the transport path from the approach path.

  According to this method, it is possible to avoid the passing of the transport vehicle under the girder of the moving portal crane, and to optimize the movement of the portal crane and the transport vehicle while ensuring safety. , Cargo handling efficiency can be improved.

  According to the container terminal, the portal crane and the container terminal operation method of the present invention, it is avoided that the transport vehicle passes under the girder of the moving portal crane and the movement of the portal crane is completed. During this period, it is possible to reduce waiting for the transport vehicle and waiting for the portal crane until the transport vehicle passes through the transport path. Thereby, each movement of the portal crane and the transport vehicle can be optimized while ensuring safety, and the cargo handling efficiency can be improved.

Of a load balance adjustment mechanism for both legs 24 in a state where the container C is suspended by the spreader 22. At least one of them.

  Since the structure of the portal crane 20B is the same as that of the portal crane 20A, the description thereof is omitted.

  Next, an operation method of the container terminal 10 will be described. Here, a description will be given of an example of a carrying-in operation for storing the container C transported from the outside by the container truck 30 in the storage lane 11. In addition, here, the storage position of the container C transported to the container truck 30 in the storage lane 11 is P arranged on the inlet 15a side. Accordingly, the travel route of the container truck 30 is a travel route that travels in order on the transport route 15 and the exit route 17.

  As shown in FIG. 1, when the container truck 30 enters the container terminal 10 from the gate 12, the pointing device 12 b of the gate 12 moves the container truck 30 to the storage position P and the transportation path of the container C instructed from the control device 14. 15 and the travel route for traveling on the exit route 17 in order.

  Next, as shown in FIG. 2, the container truck 30 travels to the entrance 15a of the transport path 15 according to the instruction of the instruction device 12b. Further, the control device 14 moves the portal crane 20A to the block at the storage position P of the container C by remote control. At this time, since the portal crane 20A is moving in the section between the entrance 15c and the entrance 15a, the control device 14 lowers the entrance gate blocking bar 18a in conjunction with the movement of the portal crane 20A. The inlet 15a is closed. Thereby, while the portal crane 20A is moving, the container truck 30 can be stopped at the entrance 15a by the entrance gate. If the portal crane 20A is not moving when the container truck 30 arrives at the entrance 15a, the container truck 30 enters the transport path 15 without stopping at the entrance 15a.

  Next, when the portal crane 20A arrives at the block at the storage position P, the control device 14 stops the movement of the portal crane 20A. And the control apparatus 14 rotates the breaking bar 28a of the breaker 28 of the portal crane 20A in a horizontal direction, and closes the conveyance path 15. FIG.

  Next, as shown in FIG. 4, the control device 14 raises the blocking rod 18a and opens the inlet 15a. Then, the container truck 30 enters the transport path 15 from the opened entrance 15a, travels along the transport path 15 to a position below the girder 23 of the portal crane 20A, and stops. At this time, the container truck 30 is stopped in accordance with the blocking bar 28a of the blocking machine 28 of the portal crane 20A, so that the stopping position of the container truck 30 is an optimum position for loading and unloading the container C.

  Next, as shown in FIG. 5, the control device 14 causes the trolley 21 of the portal crane 20 </ b> A to traverse, and raises / lowers the spreader 22 to cause the portal crane 20 </ b> A to start loading and unloading the container C. Next, the control device 14 confirms the safety in loading / unloading of the container C because the container C has moved from the container truck 30 onto the storage lane 11, and the portal crane 20 </ b> B on the path on which the container truck 30 will travel from now on. Make sure is not moving. Next, the control device 14 displays a signal for restarting the traveling of the container truck 30 on the display 27. Further, the barrier bar 28a of the breaker 28 is rotated in the horizontal direction to open the transport path 15. If it takes time to load and unload the container C, or if the portal crane 20B has moved on the path of the container truck 30, the container is not signaled to resume running until these are completed. The truck 30 is put on standby.

  Next, the container truck 30 travels along the transport path 15 and exits to the exit path 17 from the exit 15d. Next, the container truck 30 travels on the exit path 17 and bypasses the portal crane 20B. Then, the vehicle travels on the circulation path 13 and exits from the gate 12 to the outside of the container terminal 10 to complete the operation method.

  The above operation method is an example in which the storage position in the storage lane 11 of the container C transported to the container truck 30 is arranged on the inlet 15a side. On the other hand, when the storage position of the container C in the storage lane 11 is on the outlet 15b side, the travel route of the container truck 30 is a route that travels in the entrance route 16 and the transport route 15 in this order. In this case, first, the container truck 30 travels along the approach path 16 and bypasses the portal crane 20A. The operation of the entrance gate 18B in conjunction with the movement of the other portal crane 20B, the operation of the breaker 28 in conjunction with the loading and unloading of the container C of the portal crane 20B, etc. are the same as the above operation method.

  Further, when the container C stored in the storage lane 11 is carried out of the container terminal 10, the same operation method as described above is used.

  According to the container terminal 10 and the operation method thereof according to this embodiment, first, as shown in FIG. 1, an approach path 16 that bypasses the portal crane 20A and an exit path that bypasses the portal crane 20B are disposed in the container truck 30. 17 is run. Thus, the gate cranes 20A and 20B are moved until the container truck 30 waits without entering the transport path 15 and the container truck 30 passes through the transport path 15 until the gate cranes 20A and 20B finish moving. The time for waiting for the cranes 20A and 20B can be shortened. In addition, the distance that the container truck 30 travels on the transportation path 15 can be shortened, and at the same time, transportation by a plurality of container trucks 30 can be handled.

  Secondly, as shown in FIG. 2, when the container C is unloaded at the entrance 15a side of the transport path 15 of the storage lane 11 and the portal crane 20A is moving, the container truck 30 is moved to the transport path 15. Stop at the entrance 15a before entering. Specifically, the control device 14 lowers the blocking bar 18a of the entrance gate 18A and closes the inlet 15a in conjunction with the movement of the portal crane 20A. Thereby, it can avoid that the container truck 30 passes under the moving portal crane 20A, and the safety | security of the manned container truck 30 can be ensured.

  Third, as shown in FIG. 3, by using a portal crane 20A having an indicator 27 and a breaker 28, a container truck 30 stopped when loading and unloading the container C is used as a container for the portal crane 20A. It can be made to wait until safety can be confirmed based on the loading / unloading work status of C and the moving status of the portal crane 20B. Then, as soon as safety can be confirmed, a signal to resume running is displayed on the display 27, and the conveyance path 15 is opened by the shutting bar 28a of the breaker 28. Accordingly, when the container C is loaded and unloaded, the container truck 30 resumes traveling in a state where safety cannot be confirmed, and when the container truck 30 resumes traveling, under the portal crane 20B that is moving at the traveling destination. It is possible to avoid diving, colliding with the container truck 30 that has entered the transport path 15 from the approach path 16.

  For the above reasons, according to the container terminal 10 and its operation method of the embodiment, the movements of the portal cranes 20A, 20B and the container truck 30 are optimized while ensuring safety, and the cargo handling efficiency is improved. Can be made.

  In particular, this container terminal 10 and its operation method are most suitable for a conventional container terminal having a storage lane 11 whose length direction is directed along the edge of the quay. At present, it is underway to improve the handling efficiency by deploying remotely operated portal cranes 20A and 20B in this type of conventional container terminal. However, in the conventional container terminal, there are many opportunities for the manned container truck 30 to pass under the gate-type cranes 20A and 20B, so ensuring safety is an issue. Therefore, according to the container terminal 10 and the operation method thereof, the trade-off problem of ensuring safety and improving cargo handling efficiency can be solved simultaneously.

  In the embodiment, the container truck 30 is taken as an example of the transport vehicle. However, a transport vehicle that circulates between a crane for loading and unloading containers from a ship and a storage lane may be used.

  In the embodiment, the remote-controlled RTG is taken as an example of the portal cranes 20A and 20B. However, an RMG (rail-type portal crane) that travels on a rail laid along the storage lane may be used.

  Further, the configurations of the entrance gates 18A and 18B and the breaker 28 according to the embodiment are not limited to the above configurations. For example, you may comprise a gate with one breaker as an entrance gate. Moreover, the structure which raises / lowers a barrier rod and the structure which rotates a barrier rod horizontally can be changed suitably as a structure of a circuit breaker.
