Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application]
The present invention relates to a mobile chassis loader that guides a lower edge of a container suspended by a container crane and loads the container on a positioned chassis.

[Prior Art] Conventionally, when a container is lifted from a ship by a container crane and placed on a chassis on the ground, a movable guide is brought into contact with the chassis to adjust the position when the chassis is out of position. There has been a chassis loader for loading the lower edge of a container, which is hung by a container crane, on the chassis positioned by the inclined surface of the guide.

[Problems to be solved by the invention]

However, the chassis loader 5 having the conventional configuration as described above is used.
Is fixed to the portal beam 4 whose both ends are supported by the sea side leg 2 and the land side leg 3 of the container crane of the container crane as shown in FIGS. 8 and 9, or the legs 2, 3 of the container crane. And is fixed to the sill beam. As shown in the figure, the position where the container 8 is placed on the chassis 7 is
It is limited to one place.

Therefore, the container ship has become larger and the cargo handling has
When using two container cranes and three container cranes for a ship at the same time, if the chassis loader 5 is fixed at the same position as shown in FIG. Existing chassis 7 and container crane legs
There was a problem that it intersected between 2 and 3 and was very dangerous.
Further, when the chassis 7 changes its course greatly, the guide of the chassis loader 5 comes into contact with the chassis 7, and thus the chassis 7 cannot be stopped within an effective range.

In order to prevent the intersection of chassis 7 in this way,
As shown in the figure, it is possible to change the fixed position of the chassis loader 5 for each adjacent container crane,
If the chassis loader 5 is positioned near the center between the container crane legs 2 and 3 in this method, there is a problem that it is dangerous to accidentally hit the chassis 7 against the chassis loader 5 when the visibility is poor such as night loading. It was Also,
When the cargo is handled by a straddle carrier (not shown) or the like, there is a problem that not only the chassis loader 5 becomes an obstacle but also the straddle carrier may hit the chassis loader 5 as in the above case.

The present invention has been made in view of the above-mentioned problems, and when the above problems are eliminated and adjacent container cranes simultaneously load and unload, the chassis do not intersect and safe during night loading and loading by a straddle carrier. The purpose is to provide a chassis loader that can work.

[Means for solving problems]

In order to solve the above problems, the present invention relates to a rail provided on a portal beam whose both ends are supported by a sea-side leg and a land-side leg of the container crane, which are arranged in a direction substantially orthogonal to the traveling direction of the container crane. A traverse carriage supported by traverse wheels for traveling, and a chassis loader for guiding the container when the container is loaded on the chassis by a container crane, and the suspension loader is supported by the traverse carriage by a pillar, In addition, the traverse carriage is provided with wheels that are in contact with the side surface of the portal beam that supports an external force applied to the pillar or the chassis loader and prevents an excessive force from being applied to the rail.

[Action]

By configuring the chassis loader as described above, the chassis loader is configured to be attached to the transverse carriage via the pillar, so that the chassis loader is movable between the sea side leg and the land side leg of the container crane, Not only can the cargo be loaded near the land-side legs and the cargo can be loaded near the sea-side legs, but it can also be loaded at the central portion between the sea-side legs and the land-side legs. In other words, if two container cranes load side by side, one unit uses the chassis loader on the land side, and the other unit uses it near the center or near the sea, the cargo can be handled safely without the chassis crossing. Can be done.

Further, during nighttime driving or loading and unloading by the straddle carrier, it is possible to stop using the chassis loader near the center and store the chassis loader at the sea side, the land side, or any safe position.

In the figure, reference numeral 1 denotes a container crane, which supports a portal beam 4 by a sea-side leg 2 and a land-side leg 3. The chassis loader 5 is a guide for constructing the container 8 on the chassis 7 by utilizing the inclination formed when the movable arm 6 contacts the chassis 7, and is suspended from the portal beam 4 by a column 9.

The portal beam 4 is a traverse wheel 10 of the chassis loader 5.
Rails 11a, 11b for traveling a, 10b and steel plates 13a, 13b for contacting wheels 12a, 12b for interfering with excessive displacement of the chassis loader are attached.

FIG. 3 is a perspective view showing details of the portion B of FIG. 1, and FIG. 4 is a view taken along the line AA of FIG. As shown in the figure, the traverse wheel 10a is a rail 11a provided on the portal beam 4.
The upper part is driven by an electric motor 14 (see FIG. 2). Further, the wheel 12b is adapted to abut on a steel plate 13b provided on the side surface of the portal beam 4. Although not shown in detail, the traverse wheel 10b is driven by the electric motor 14 on the rail 11b provided on the portal beam 4 as described above. Further, the wheel 12a is adapted to contact a steel plate 13a provided on the side surface of the portal beam 4.

The traverse wheel 10a is fixed to the bogie frame 15 and
The pillar 9 of the chassis loader 5 is connected to the pillar 9 by a pin 16. Further, a bracket 15a is provided on the trolley frame body 15 in order to fix the position of the chassis loader 5 during storage during work, and a pin 17 is provided in a hole provided in the bracket 15a.
