DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal cargo handling delivery device used for loading containers on a container transport ship.

[0002]

2. Description of the Related Art In general, as a container handling system between a quay and a ship, a lift-on / lift-off system using a container crane is known. However, in such a lift-on / lift-off method, in addition to transferring the container in the horizontal direction, the container is also transferred in the vertical direction, so that it takes a long time to transfer the container. It is not suitable for the system.

[0003] In recent years, there has been proposed a method of connecting a ship to a quay with a delivery device, and transporting the container on the delivery device using a self-propelled truck exclusively used for horizontal loading and unloading of containers. FIG.
FIG. 2 is a perspective view of a cargo handling device used for implementing such a horizontal cargo handling system. In the figure, reference numeral 20 denotes a ship, on which a container support base 22 for supporting a container 21 is installed on a deck 20a. A delivery device 26 for moving a self-propelled carriage 25 loaded with a plurality of containers 24 is installed on the quay 23. The delivery device 26 is mounted on a ship-side lamp 2 that is pivotally mounted on its front and back so as to swing vertically.
6a and a quayside lamp 26b, and the tip of the shipside lamp 26a is bridged on the deck 20a.

Further, traveling guides 26d and 22a for traveling and guiding the self-propelled carriage 25 are provided on both sides of the traveling path 26c of the delivery device 26 and the container supporting gantry 22 on the deck 20a. As shown in FIG. 6, the self-propelled trolley 25 is provided with a guide roller 25 provided below the self-propelled trolley 25.
The vehicle travels on the delivery device 26 and on the deck 20a while being guided by the traveling guide 26a and the traveling guides 26d and 22a.

[0005]

However, since the hull of a ship berthing on the quay is affected by waves, wind, etc., it is necessary that the delivery device 26 can follow the sway properly. Becomes In particular, it is necessary to prevent the connecting portion between the traveling guide 26d of the ship side ramp 26a and the traveling guide 22a on the deck 20a from being displaced. The reason for this is that the self-propelled vehicle 25
Is caused, the guide roller 25a may fit into the gap between the connection portions and the self-propelled vehicle 25 may not be able to travel.

The present invention has been made in order to solve such a problem, and can follow the fluctuation even when the hull sways, and smoothly guide the self-propelled carriage 25 from the delivery device 26 to the deck side. It is an object of the present invention to obtain a horizontal cargo handling delivery device capable of carrying out.

[0007]

A delivery apparatus for horizontal cargo handling according to the present invention is provided with a delivery stage installed on a quay side and a shaft mounted on a ship-side end of the delivery stage so as to be vertically swingable. A ramp, a guide plate provided on both sides of the ramp and the delivery stage, and on the ship side for guiding the self-propelled bogie; A base flap movably mounted on the shaft, and a guide having one end side slidably mounted on the marine vessel side of the guide plate on both sides of the lamp so as to be horizontally swingable and the other end side provided on the marine vessel side. A side flap configured to be able to abut on the plate; and urging means for constantly urging the other end of the side flap toward an inner wall of a guide plate provided on the marine vessel side.

Further, the quay-side end of the guide plate provided on the ship is curved outward.

[0009]

In the horizontal cargo handling delivery device configured as described above, when a ship berthed on the quay rocks vertically, the lamp swings vertically with respect to the delivery stage. Follow the shaking. When the ship swings in the front-rear and left-right directions, the side flaps follow the swing by swinging in the horizontal direction with respect to the ramp while abutting against the inner wall of the guide plate provided on the ship side. Furthermore, when the ship rolls, the base flap follows the rocking by swinging up and down with respect to the ramp.

[0010]

FIG. 1 is an explanatory view of an embodiment of a delivery apparatus for horizontal cargo handling according to the present invention, and FIG. 2 is an enlarged view of a main part of FIG. In the figure, the same parts as those in FIG. Reference numeral 1 denotes a guide plate provided at both ends of the container support base 22 on the quay side on a continuation of the traveling guide 22a, and has a distal end curved in an arc shape outward. Reference numeral 2 denotes a side flap which is rotatably pivotally mounted on the guide plate 26d at one end thereof continuously to the ship-side end of the guide plate 26d, and has the other end in contact with the inner wall of the guide plate 1. 3 is at the ship side end of the ship side lamp 26a,
This is a base flap that is pivotally attached to the traveling path so that it can swing vertically. As shown in FIG. 3, the base flap 3 is pivotally attached to the tip of the marine vessel lamp 26a by the pin 4 and has such a structure.
The tip of 6a can be landed on a plane.

Reference numeral 5 denotes a hydraulic cylinder having the rod side fixed to the outer wall of the side flap 2 and the cylinder side fixed to the base flap 3, respectively, for urging the side flap 2 outward. The hydraulic cylinder 5 is connected to a hydraulic controller (not shown) by a hydraulic pipe, and is configured to pull the side flap 2 toward the guide plate 1 with a predetermined force even when the side flap 1 swings.

FIG. 4 is an explanatory diagram for explaining the operation of this embodiment. The operation of the present embodiment configured as described above will be described with reference to FIG. When the ship berthing on the quay sways under the influence of the waves and wind and moves rightward in the figure with respect to the ship side ramp 26a, the container support base 22 and the ship The position of the center line of the side lamp 26a is shifted. At this time, the tip of the side flap 2 swings while abutting on the guide plate 1, and the side flap 2 can follow the guide plate 1 without separating. Conversely, when the ship moves leftward in the figure with respect to the ship side lamp 26a, the side flaps 2 also follow the guide plate 1 without separating, as shown in FIG.

Further, even when the ship is displaced in the horizontal rotation direction with respect to the ship-side lamp 26a, the side flaps 2 follow the guide plate 1 without separating as shown in FIG. As described above, when the ship swings in the front-rear and left-right directions, the ship-side lamp 26 is held in a state where the side flap 2 is in contact with the inner wall of the guide plate 1 at its tip.
a, the ship-side lamp 26
a and the guide plate 1 on the deck 20a do not have a gap.

While the above description has been made on the horizontal swing,
In the case where the ship swings in the vertical direction, the base flap 3 and the ship side lamp 26a are pivotally mounted on the ship in the vertical direction, so that they can follow the movement of the ship by swinging. .

In the above embodiment, an example is shown in which the hydraulic cylinder 5 is used as means for pulling the side flaps 2 outward and making contact with the guide plate 1, but the present invention is not limited to this. The side flap 2 may be pulled outward by an elastic member such as a spring.

[0016]

As described above, according to the present invention, the ramp and the base flap can be swung in the vertical direction, and the side flap can be swung in the horizontal direction while abutting against the inner wall of the guide plate provided on the ship side. , So that even if the vessel shakes, it can follow it, and there is no gap between the side plate and the guide plate provided on the vessel side, and the self-propelled bogie can operate smoothly Becomes

Also, since the quay-side end of the guide plate provided on the ship is curved outward, the side flaps can smoothly swing in the horizontal direction.
