Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a marine lamp. More specifically, the present invention relates to a marine ramp for allowing automobiles to enter and exit a so-called roll-on-roll-off type ship body on which automobiles are mounted.

Previous marine ramps consisted of two panels with one end rotatably connected, with the other end of one panel attached to the ship's hull and the other end of the other panel grounded to the shore. When the deck on which the marine ramp is installed is at approximately the same level as the deck, cars can pass through without difficulty, but when the deck on which the marine ramp is installed is placed at a significantly lower level than the shore due to tide level and cargo, the hull Not only are the side panels placed at a very steep slope with respect to the horizon, but the connecting portions of both panels point upwards and protrude excessively, causing inconveniences such as rubbing against the muffler of the automobile, thus impeding safe passage. In order to prevent such a situation, measures such as changing the water level of the ship's hull or waiting for the tide level to improve can be considered, but the time loss caused by this would be irreparable. The present invention aims to solve this type of problem that occurs with previous marine lamps.

It is an object of the present invention to safely construct a ramp between the ship's hull and the shore without creating an abnormal raised part in the passage even if there is a considerable difference in height between the deck on which the ramp is attached and the shore. The object of the present invention is to obtain a marine ramp that can allow automobiles to pass through.

According to the present invention, the first panel has one end connected to the ship's hull via a rotation shaft and the opposite end extends toward the shore when in use; A marine lamp is provided with a second panel that is connected to a second panel and whose opposite end is placed on shore when in use, and the first panel is folded and stored in a peripheral portion of a ship's hull when not in use.
A rotating shaft attached to the one end of the panel is supported by the lower ends of a pair of rotating arms whose upper ends are rotatably attached to the hull at a predetermined height position adjacent to the lamp storage position, and the first panel There is obtained a marine lamp characterized in that an inboard flap is rotatably attached to the one end.

Now, an embodiment of the apparatus of the present invention will be described below with reference to the accompanying drawings.

With reference to Figures 1 and 2, the hull deck 13
The right end is attached to the first panel 1, and the left end extends toward the land when in use, and the right end is rotatably connected to the left end of the first panel 1 via the rotation shaft 4, and the left end is extended toward the land when in use. A marine lamp 10 is shown comprising a second panel 2 placed on shore. When the marine lamp 10 is not in use, the first and second panels 1 and 2 are folded up and stored in an upright position. In the lamp 10 of the present invention, an inboard flap 9 is rotatably attached to the right end of the first panel 1 by means of a rotation shaft 3. The inboard flap 9 further has a tip end flap 11 attached to the end opposite to the pivot shaft 3 via a pivot pin 22. As shown in Fig. 2, the rotation axis 3
A pair of pivot pins 8, 8 placed on an extension of the pivot shaft 3 at positions adjacent to both ends of the pivot shaft 3 are attached to the first panel 1. A rotating arm 5 having a predetermined length has its upper end rotatably attached to the hull by a rotating pin 6 at a position at a predetermined height H adjacent to the storage position of the marine lamp 10. Such rotating arms 5 are provided on both sides of the marine lamp 10. The lower end of each rotating arm 5 is connected to the rotating pins 8, 8, respectively. Therefore, the right end of the first panel 1 shown in FIG.
It is suspended from the rotation pins 6,6. As shown in FIGS. 1 and 3, a drive source such as a hydraulic cylinder 7 has one end attached to the hull through a pivot pin 23 and the opposite end connected to the pivot arm 5 via a pivot pin 24. Therefore, the pair of rotating arms 5, 5 are reciprocated between the dotted chain line position and the solid line position in FIG. 3 by the drive sources 7, 7 attached to each. The dotted chain line position is a position where the pair of rotating arms 5, 5 are placed vertically, and in this position, the marine lamp 10 is placed in the first position.
This is similar to previous marine lamps in which the inboard end of the panel is hinged directly to the deck. When there is no height difference between the deck 13 and the shore 14, the ramp 10 is used in this state. A mechanism for locking the rotation pins 8, 8 in this position is provided if necessary (not shown). The solid line position in Figure 3 is the first
This shows the state in which the inboard end of the panel 1 is pushed out toward the shore and simultaneously lifted off the deck 13.As will be explained later, by lifting the right end of the first panel 1 via the pivot pin 8, the horizontal line The slope of the first panel 1 relative to the first panel 1 can be reduced. Also,
Since the inboard end of the first panel 1 is pushed out toward the shore in this way, the length of the first panel 1 can be shortened. The inboard flap 9 is provided with a roller 21 on the lower surface of the edge portion on the opposite side from the rotation shaft 3, and follows the movement of the right end of the first panel 1 and reciprocates between the dotted chain line position and the solid line position. If necessary, a mechanism for locking the roller 21 in the position shown by the solid line in FIG. 3 may be provided.

In use, when the right end of the first panel 1 of the marine ramp 10 is pushed out and lifted out of the vessel by the operation of the rotating arms 5, 5 (Fig. 4), the slope α of the first panel 1 with respect to the horizontal line is reduced. can be done. When reducing the gradient α, the angle β formed by the first and second panels 1 and 2 at the rotation axis 4 can be reduced. By reducing the angle β, it is possible to prevent a car from scraping its underbelly when passing through the ramp 10 and to safely introduce it into the ship's hull. On the other hand, in the conventional marine lamp shown in FIG. 6, the rotation shaft 3 is fixed to the hull, and the slope α of the first panel 1 caused by the difference in height between the ship's deck 13 and the shore 14 is The ramps themselves cannot be adjusted and are forced to alter the ship's water or wait for the tide to change.

FIG. 5 shows the process of swinging out the first panel 1 of the lamp 10 of the present invention to the solid line position in FIG.
First, by loosening the wire 17 connected to the first panel 1, the first and second panels 1 and 2 are lowered from the storage position to the position immediately before the bridge, and then the drive cylinders 7, 7 are actuated to move the rotating arms 5, After lifting the marine ramp 10 into position by swinging the wire 5 overboard, the ramp 10 can be placed in the bridge position when the wire 17 is further loosened.

The effect of the device of the present invention is that even if there is a height difference between the deck on which the ramp is installed and the shore, the angles α and β can be reduced during use, as well as the ability to rotate. By pushing out the shaft 8 and the inboard flap 9 toward the shore, the length of the first panel 1 and, by extension, the length of the entire lamp can be shortened.
