Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hinged ramp installed between the upper and lower decks of a Car Hue IJ-1 car carrier and used for the passage of vehicles carried on these ships.

Conventionally, in order for vehicles such as car ferries to move between decks of different heights, ramps were built between the decks. Then pass through these ramps between the decks and reach the destination deck 1.
A method of self-propelled and mounted on a tower has been adopted.

Conventional ramps include the fixed ramp a shown in Figure 1a, the upper and lower flat integrated ramp B shown in Figure 1, and the upper and lower bending integrated ramp C shown in Figure 1C. A ramp is fixedly installed as part of the ship's hull structure, and is excellent in terms of strength and stability, but it creates a putt space at the bottom and top of the ramp, making it impossible to load vehicles in these positions. Therefore, the total number of vehicles that can be transported is reduced, which is a major drawback in terms of ship operation efficiency.

In addition, in order to prevent the generation of chit space, which is a drawback of fixed slopes, the vertical and flat integrated slopes are configured with flat panels, one end of which is pivoted to the upper deck, and the other end can be moved up and down. Therefore, the flat panel can be used as both a ramp and a part of the upper deck.
From the standpoint of preventing butt-rubbing or head-rubbing, it is necessary to limit the inclination angle of the ramp to a certain value or less, which increases the length of the ramp and impairs the economical use of space.
Disadvantages include the need for a large amount of driving force to move the ramp to the upper deck for storage, and the equipment required to have a large capacity.

In addition, the up-and-down type bending integrated ramp has a bend in the middle of the ramp surface to compensate for the drawbacks of the above-mentioned up-and-down type planar integrated ramp, but when the ramp is stored in the upper deck, As shown in the figure, the curved part in the middle of the ramp protrudes vertically, and in order to increase operational efficiency, the height between the decks is adjusted to the height of the cargo on the tower, and in order to take up as little free space as possible, both the upper and lower parts of these ships are There are places where the height between the decks is insufficient, and these places become put spaces, reducing operational efficiency, and it is difficult to pass and load vehicles on the upper deck when the slope is stowed, as shown by the dashed-dotted line in Figure 1C. There were drawbacks such as:

The present invention aims to eliminate these drawbacks of conventional devices, and by constructing a ramp with three or more panels and connecting these panels with a hinge, the chit space for forming a ramp can be reduced. Even when the ramp is stored in the upper deck, it remains flush with the upper deck, and it prevents belly scraping, butt rubbing, and head rubbing without making it difficult for vehicles on the upper deck to pass through or onto the deck. It is an object of the present invention to provide a hinged ramp whose length is reduced.

For this reason, the hinged ramp of the present invention is used for ramps that are hung between the upper and lower decks in order to transfer vehicles to positions at different heights. between a first panel having one edge pivotally connected to the first panel, the notch end of the upper deck opposite to the pivoting side of the first panel, and the lower deck substantially directly below the end; A second panel comprising a third panel having a movable edge, and at least one panel having both ends pivotally connected to the other edge opposite to the one edge of the first panel and the third panel. panels, support fittings for suspending these panels from the upper deck to form a ramp, and cutouts such that these panels are stored in cutouts in the upper deck and form part of the upper deck. It is characterized by consisting of a storage support device that protrudes from around the notch to the bottom of the panel and supports the panel, and a panel moving device that stores the panels forming the ramp into the notch in the upper deck.

An explanation of the embodiment of the present invention with underground drawings:
FIG. 2 is a side view of an embodiment of the present invention, in which the solid line shows the hinged ramp of the present invention in use, and the dash-dotted line shows the state stored in the upper deck.

Further, FIG. 3 is a plan view of the state indicated by the dashed line in FIG. 2.

1 is a first panel whose one end edge 19 is pivotally attached to one end 23 of the notch 22 of the upper deck 20 with a hull mounting hinge 4; 3 is the other end 24 of the notch 22 of the upper deck 20; One edge 1 of the lower deck 21 is located between the edges 24 and 25 of the lower deck 21.
4 is a movable third panel; 2 is a movable third panel; Although the second panel is shown as a single panel, the second panel is connected by two, three, and so on.
It is also possible to separate them into two pieces and pivot them to each other.

7.8 is a stopper that prevents the panels from rotating in opposite directions, and 9 is the first . Second. In order to support the own weight and the weight of passing vehicles when a ramp is formed in the third panel as shown by the solid line in Figure 2, a support metal fitting is provided on the side edge of the notch 22 to suspend it from the upper deck. It has a structure that allows it to be folded in half.

Reference numeral 10 denotes a storage support device that projects and supports the hinged ramp of the present invention into the notch 22 of the upper deck 20 when it is stored in the notch 22 of the upper deck 20, and has a structure in which the supporting portion can be pushed out and retracted by hydraulic pressure. It is being done.

Reference numeral 11 is a driving cigar cylinder installed on the back of the upper deck, and a cable 1 is attached to a sheep 13 installed at the side edge of the notch 22 of the upper deck 20 and the lower part of the hinged ramp.
2 is expanded and contracted to apply tension and move from the slope forming position to the storage position or vice versa, and together with the sheep 13 and the cables 12 constitute a panel moving device.

Therefore, when the hinged ramp of the present invention is used as a ramp, that is, when the hinge is down, the weight of the ramp and the weight of passing vehicles are absorbed by the hull mounting hinge 4, the support fittings 9, and one end edge 14 of the third panel 3. Supported.

In addition, when it is stored flush with the upper deck 20, so-called hinge-up, it is supported by the hull mounting hinge 4 and the storage support device 10.

In order to maintain the levelness, stoppers 7 and 8 are provided to assist in maintaining the levelness.

The storage support device 10 is of a hydraulically driven ram type. Second
．． When the third panel is moved up or down, the ram is retracted into the hull structure.

As mentioned above, the hinged slope of the present invention has a simple structure in which the slope panel is divided into three or more panels and the panels are hinged to each other, thereby solving the disadvantages of conventional devices as follows. There are advantages to be solved.

(1) When hinged up and stored on the upper deck, it is flush with the deck and does not interfere with vehicle passage or storage.

(2) The overall length of the ramp can be shortened by making the slope of the middle panel more steeper than the panels at both ends.

(3) By keeping the slope of both end panels at about 7 degrees, the vehicle does not rub its belly, butt, or head.

(4) As the total length of the slope is shortened, the driving force required for storing and installing them is small, and related equipment can be made smaller.
