DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shipboard rain protection device used for cargo handling in rainy weather.

[0002]

2. Description of the Related Art In general, luggage that is difficult to get wet with rain, such as steel coils, cannot be handled in rainy weather, so berthing charges for a carrier ship increase and the delivery date tends to be uncertain. 2. Description of the Related Art Conventionally, a technique has been proposed in which an all-weather berth is constructed in a harbor, and a carrier and a crane are covered with a huge roof to enable cargo handling in rainy weather. However, the all-weather berth required a large-scale renovation work covering the entire bay facility, and had the problem that the facility cost was huge.

The frame is supported on the pedestal so that the height can be adjusted so that the height of the frame can be changed according to the height of the hatch. The pedestal is assembled to the frame so that the position of the pedestal can be adjusted in the width direction of the carrier so that the position of the pedestal can be changed according to the width of the carrier and the hatch. In order to prevent rain from falling down, a side seat is provided on the frame so as to be openable and closable in a vertical plane. Hanging hooks are provided on the frame so that the device can be carried into and out of the carrier by a crane.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show the entirety of a facility for loading and unloading a steel coil 1 in rainy weather. The rain load handling equipment includes a ram truck 5 that transports a pallet 2 on which a plurality of coils 1 are placed between a warehouse 3 of a steel mill and a quay 4, a luggage cover 6 mounted on the ram truck 5 together with the pallet 2, Onshore cover device 7 installed on quay 4 and onboard rain protection device 10 installed on carrier 8
And a portal crane 11 for transferring the coil 1 between the land cover device 7 and the onboard rain protection device 10.

The ram truck 5 is equipped with a hydraulic ram (not shown) for lifting and lowering the pallet 2. The luggage cover 6 is large enough to cover all the coils 1 and has a hood shape, and is detachably attached to the ram truck 5. An umbrella 13 is attached to the hanging tool 12 of the crane 11 so as to cover the coil 1 from above. The land cover device 7 is provided with an openable / closable skylight 14 through which the hanger 12 enters and exits, and the shipboard rain protection device 10 is also provided with an entrance / exit 15 through which the hanger 12 enters and exits.

As shown in FIGS. 3, 4 and 5, the onboard rain protection device 10 is a portable steel structure, and includes a frame 29 having a size surrounding the hatch 9 of the carrier 8 and a frame 29. Four pillars 30 supported horizontally above the hatch 9
And The frame 29 is formed in a flat rectangular shape, and a pair of foldable rainproof covers 31 forming the entrance 15 of the hanging tool 12 are stretched inside the frame 29 so as to be openable and closable in the boat width direction. Each rainproof cover 31 is opened / closed by a mechanism including two motors 37 and a chain 38 so that the opening area of the entrance 15 and the position in the boat width direction can be changed.

A motor 29 is mounted on a frame 29.
A carriage 33 is provided along the rail 34 so as to be movable in the boat width direction. Vertical guides 35 are fixed to each carriage 33, and the pillars 30 are attached to these guides 35 by motors 36.
It is attached so that it can go up and down. This allows
The frame 29 is supported on the pedestal 30 so as to be adjustable in height, and the pedestal 30 is assembled to the frame 29 so as to be adjustable in the ship width direction. The height of the frame 29 is changed according to the height of the hatch 9. The position of the pillar 30 can be changed according to the width of the carrier 8 and the width of the hatch 9.

As shown in FIG. 5, on a long side of the frame 29, a side sheet 40 for preventing rain from falling sideways before and after the hatch 9 is provided so as to be opened and closed in a vertical plane by a winding motor 41. . A gutter 39 for discharging rain that has flowed down from the edge of the rainproof cover 31 is attached to the inside of the side sheet 40. On the upper surface of the frame 29, four hanging hooks 42 for carrying the onboard rain protection device 10 into and out of the carrier 8 by the crane 11 are fixed.

The hanging tool 12 of the crane 11 includes a hanging beam 44 and a coil lifter 45. Umbrella 1
3 is attached to the support frame 48 of the suspension beam 44 so as to be detachable, and the umbrella 13 is attached to the onboard
In this state, only the hanger 12 moves up and down in the hold. The suspension beam 44 has a cylindrical cover 5 made of a transparent flexible material for protecting the coil 1 from rain falling down.
6 are suspended.

Next, a cargo handling method in rainy weather will be described with reference to FIGS. When loading the coil 1, first, the land cover device 7 is installed on the quay 4 by the crane 11, the onboard rain protection device 10 is similarly installed on the carrier 8, and the hanging tool 12 is attached to the crane hook 47. When installing the onboard rain protection device 10, the position of the pillar 30 is adjusted according to the width of the carrier 8 and the hatch 9, and the height of the frame 29 is adjusted according to the height of the hatch 9.

Next, in the warehouse 3, the plurality of coils 1 are loaded on the pallet 2 and loaded on the ram truck 5, and further, the luggage cover 6 is mounted, the ram truck 5 is driven from the warehouse 3 to the quay 4, and the luggage cover 6 is lowered. Then, the ram truck 5 is stored in the land cover device 7. Then, after the skylight 14 of the land cover device 7 is opened and the coil 1 is lifted from the pallet 2 by the hanger 12, the skylight 14 is closed to prevent rainfall.

Subsequently, the crane 11 is operated and the coil 1
With the umbrella 13 covered with the umbrella 13, the hanging tool 12 is transferred from the land-based cover device 7 to the onboard rain-proof device 10. Then, with the rainproof cover 31 of the onboard rainproof device 10 opened and the entrance 15 covered with the umbrella 13, the hanging tool 12 is lowered from the hatch 9 into the hold, and the coils 1 are stacked. From the hatch 9 and the rainproof cover 31 is closed to prevent rain from falling into the hold. Thereafter, these operations are repeated, and the coils 1 are sequentially stacked in the hold, and the loading of one pallet is completed. At the time of unloading the coil 1, the same operations as during loading are performed in the reverse order.

Therefore, the on-board rain protection device 10 of this embodiment
According to this, in the cargo handling work on the transport ship 8, the coils 1 can be efficiently loaded and unloaded in the hold without getting wet with rain, and the equipment cost can be greatly reduced as compared with the all-weather berth. In addition, by adjusting the height of the frame 29 and the position of the pillar 30, the rainproof device 10 can be used for various types of carriers 8 having different specifications. Moreover,
Since the rain protection device 10 is configured to be portable, it can be installed on the carrier 8 only in rainy weather and can be used easily, and can be quickly removed to the quay 4 side which does not hinder cargo handling work in fine weather.

The present invention is not limited to the above-described embodiment. For example, the onboard rain-proof device can be applied to cargo handling of various kinds of luggage other than coils, and the rain-proof cover can be configured as a wind-up type. The shape and configuration of each part can be appropriately changed without departing from the spirit of the present invention.
