Description

[Detailed Description of the Invention] The present invention relates to a lamp device installed in a ro-ro boat or the like.

A ro-ro ship is equipped with a ramp that connects the ship's hull and the quay. For example, in the case of a heavy transport ship, etc., a wide ramp is provided to allow large vehicles to run, and conventionally there are ramps as shown in FIGS. 1 and 2.

In this lamp device 1, a main lamp 4 is connected to the center of a rear edge 3 of a hull 2. The main lamp 4 has its base end 5 rotatably connected by a hinge, and its rotatable tip 6 is grounded on the quay 7.

Sub lamps 8 are arranged on both sides of the main lamp 4, respectively. The sub-lamp 8 is a so-called pontoon type installed using a crane etc.
It is usually located somewhere else.

During cargo handling using this ramp device 1, as shown in FIG. 1, the main ramp 4 and both sub-ramps 8 connect the hull 2 and the quay 7 to provide a wide ramp.

When storing the lamp device 1, the main lamp 4 is held upright as shown by the solid line in FIG. 2, while the sub-lamp 8 is moved to a storage location on the deck 10 (not shown) using a crane or the like.

When the front of the quay 7 or the running vehicle is small, only the main lamp 4 is used to communicate with the quay 7, and the sub-lamp 8 is stored in a place separate from the main lamp 4. This is if the sub-lamp 8 is hinged and stands upright on both sides of the main lamp 4 in its retracted state.
This is because it may become a hindrance to vehicles running on the main lamp 4 or may obstruct their visibility.

However, there is a problem in that it takes time and effort to store the sub-lamp 8 because such an operation is performed using a crane or the like. Furthermore, since the sub-lamp 8 is stored on the deck 10, there is a problem in that the usable space on the deck 10 is reduced.

The present invention was developed in view of the above-mentioned problems, and aims to simplify the operation when storing the lamp and to make effective use of the space on the deck.

This device involves multiple ramps arranged in parallel, with their base ends rotatably connected to the hull, and the rotation range of these ramps is approximately 180° or more from the upright position with the rotating tip facing upward, so that the ramps can be hung overboard when not in use.

Embodiments of the present invention will be described below with reference to the accompanying drawings. Note that the same reference numerals are given to the same components as in the conventional example.

This lamp device 1 includes a main lamp 4 and sub lamps 8 arranged on both sides of the main lamp 4.

As shown in FIG. 3, the sub-lamp 8 has its base end 12 rotatably connected to the hull 2 via a rotating shaft 14. As shown in FIG. An arm portion 13 is formed at the base end portion 12, and the rotating shaft 14 is offset from the sub-lamp 8, thereby causing the lamp 8 to be approximately offset from the vertical plane.
It constitutes a means that can be rotated by 180°. A recess 17 is formed in the hull 2 and defined by a side wall 15 and a bottom wall 16 that are perpendicular to each other. Further, a flap 19 is located at the sub-lamp 8 and rotatably connected to the deck edge 18.

The main lamp 4 is hingedly connected to the hull 2 as in the conventional example described above.

Also, as a means for rotationally driving the sub-lamp 8,
Install a hydraulic cylinder or use a crane, etc.

Next, the effect will be explained.

If the main ramp 4 alone is used to communicate with the quay 7 without using the sub-ramp 8, the sub-ramp 8 can be connected to the offset rotating shaft 14 using a hydraulic cylinder or a crane (not shown), as shown by the solid line in FIG. It pivots around and is held in a position hanging overboard. This prevents the vehicle from interfering with vehicles traveling on the main ramp 4 and moving between the hull 2 and the quay 7.

When the lamp device 1 is stored, the sub-lamp 8 and the main lamp 4 are held in a stored position standing upright with respect to the deck 10.
, and the rotating tip 11 is directed upward. This minimizes the space on the deck 10 that the sub-lamp 8 occupies when stored.

When a large vehicle or the like is allowed to pass, the sub-ramp 8 and the main lamp 4 have their pivoting tips 11 grounded on the quay 7, thereby increasing the running width of the lamp. At this time, a flap 19 is spanned over the gap created between the sub-lamp base end 12 and the deck edge 18 to prevent the gap from becoming a hindrance to the running of the vehicle.

In summary, the present invention allows the sub-lamp to be rotated to a position where it hangs overboard, making it easy to store and rotate the sub-lamp, reducing cargo handling time, and making it possible to utilize space on the deck. This has the effect of enlarging the .
