Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a container transport device that transfers containers between a container yard provided at the back of a quay and a container ship docked at the quay.

[Conventional technology]

A conventional example of loading and unloading containers onto a container ship at a quay is explained with reference to FIG. 7. A container ship (1) berths at a quay (2), and a container crane ( 3) and (3), the container is ready to be loaded and unloaded.

At the back of the quay (2) there are an export container yard (4) and an import container yard (5).
In 4), the containers to be loaded onto the container ship (1) are handled by the yard crane (6), and at the import container yard (5), the containers to be loaded onto the container ship (1) are loaded onto the container ship (1).
The containers unloaded from the warehouse are loaded and unloaded using a yard crane (7).

Containers loaded onto a container ship (1) and transported at a quay (2)-j are loaded onto a chassis (8) by a container crane (3) and stored at an import container yard (5). The containers to be loaded on the container ship (1) are:
At the export container yard (4), the containers are loaded onto a chassis (8) by a yard crane (6), transported to a quay (2), and then loaded onto a container ship (1) by a container crane (3).

Conventionally, the Sharn (8) has been used to transport containers between the container ship (1) and the export container yard (4) and the import container yard (5), which has the following disadvantages. was there.

(1) Since there is a risk of collision of the chassis (8), the operating speed of the chassis (8) must be limited, resulting in low cargo handling efficiency.

(11) Since a large number of chassis (8) are used, a large number of workers are required.

(*ii) The cargo handling by the container crane (3) and the transportation of the chassis (8) must match, and the timing of the cargo handling by the container crane (3) and the loading/unloading of the chassis (8) may not match. Waiting time increases.

(iv) Similarly, there is a waiting time when the timing between the yard cranes (6), (7) and the chassis (8) does not match.

(V) Nyasi (8) is an export container yard (4)
Since it is necessary to take a detour around the import container yard (5) as shown by the arrow, the transport distance by the chassis (8) becomes longer.

(vl) Since the chassis (8) is operated by a man, it is difficult to automate it.

(vii) Due to the reasons (1) to (1) above, there is a limit to cargo handling efficiency.

[Problem that the invention seeks to solve]

The present invention aims to continuously and automate container transportation between a container ship and a container yard, thereby improving cargo handling efficiency and saving labor.

[Failure to solve the problem]

The present invention relates to a container crane that transports containers between a container ship and a quay, a yard crane that transports containers between a container yard provided at the back of a quay and a quay, and a yard crane that is installed along a quay to transport containers. a quay conveyor that transports containers between the crane and the yard crane;
This is a container transport device equipped with

[For production]

The work of unloading containers from a container ship involves continuous unloading of containers to a container yard using a container crane and yard crane, and the work of loading containers onto a container ship.
This will be carried out continuously using yard cranes, quay conveyors, and container cranes.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

As shown in Figure 1, the container ship 01) berthed at quay 00 has a hatch H1fl□□□, and one
Tsuchi 0 no is loaded with containers (14 cL) to be unloaded, and the other Hatsu 0 Rail α9.09 has been laid, and a container crane (16), Q

As is clear from Figure 6, from quay α [to container ship OD]
Trolley 〇咎, 01 is rail 051
It is designed to move in a direction perpendicular to the road to carry out cargo handling work. As shown in Figures 1 and 3, between the rails 151.5Q5), there is a quay conveyor ■ that moves parallel to the rail 0. ) is divided into an export container yard Qυ and an import container yard (2), and the export container yard c211 stores containers (14b) to be loaded onto the container ship αυ, and the import container yard (2 Containers (14C) unloaded from the container ship αυ are placed here.

On both sides of the export container yard Qυ, rails (c) and (c) are laid parallel to the quay αQ, and rails (c)
, (c) A yard crane (goods), (c) runs over it,
It is located so that it can be moved along the quay wall a@.

Yard cranes (I) and (I) are made with a similar mechanism, and the details are explained with reference to FIGS. 4 to 6. A long fixed girder (
2) and a moving girder 07), the moving girder (2η
moves on the movable girder rail (2) and attaches it to the fixed girder (
(b) approaches and moves away from υ. The fixed girder (a) and the movable girder (5) are attached with telescopic booms (to) that extend and retract toward the quay OQ side while being guided by guide rollers @ (see Fig. 6). As shown in Fig. 6, a chain conveyor 0υ extending in the longitudinal direction is provided on the upper surfaces of the fixed girder (a), the movable girder (5), and the telescopic boom (to), and the container (14) is placed on it. The container θ is moved to the fixed girder (
b), the movable girder (5), and the telescopic boom (to) are transported in the longitudinal direction. As mentioned above, the movable girder (5) moves on the movable girder rail (to), approaches and separates from the fixed girder (a) according to the size of the container 04), and moves onto the chain conveyor C31). Make sure that the container and 0 xun are placed stably on the container.

The top surface of the fixed girder (E) and the yard crane Q4), (
A trolley rail (to) is laid in the longitudinal direction on the upper left side in Figs. 5 and 6 of c), and the trolley (b) (see Figs. 2, 6, and 5 (see Fig. 4) runs on wheels (see Fig. 4), and can move in the longitudinal direction of the yard crane (c). As shown in Figure 5, the trolley is equipped with a spreader so that containers can be suspended from it. The chain conveyor OI) on the left side of Fig. 6 is movable in the left-right direction in Fig. 6 by cylinder 07).
With 1+ moved to the left, the trolley shown in Figure 5 (
It is now possible to lift the container suspended from the spreader (b) from the ground.

Rails (to) and (2) are laid parallel to the quay αω on both sides of the import container yard I2.
, (to) a yard crane C3 duck, +41m, runs above the quay (10) and can move in a direction parallel to the quay (10).

Yard crane C (l, +40) has a mechanism from the above-mentioned yard cranes c! Enhiru chain conveyor Cυ and yard crane C3 for hanging containers! It is equipped with a trolley that moves in the longitudinal direction of (4f).

As shown in Figures 1 to 3, between the export container yard C11) and the import container yard, a yard conveyor (431) is installed in a direction parallel to the quay 0 [ Yard Crane (Foundation), (

The trolley 〇 of the container crane αe repeats the operation of lifting the container (14a) from the hatch α and placing it on the telescopic boom (top) of the yard crane.

Since the round trip distance of the trolley α Enoki is short, the trolley (
It is possible to transport containers (14α) one after another from hatch Q2 in a short cycle time.

The container (14α) placed on the telescopic boom (toward) of yard crane Q (a) is transported by the chain conveyor 01) to the telescopic boom (toward) and yard crane C3 (see Fig. 1).
It is continuously fed to the left in FIG. 2 and placed on the yard conveyor 43. Containers placed on the yard conveyor (4th floor) are sent to the yard crane OI and placed on the yard crane handle, and transported by trolley 10 to the storage area (2nd floor).

〔Effect of the invention〕

The present invention does not use a conventional carrier for transporting containers between a container ship and a container yard, so it eliminates the need for manpower and drivers for loading and unloading the chassis, resulting in labor savings. This has the effect of improving cargo handling efficiency and facilitating automation as containers can be transported continuously.
