Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inboard lamp device installed in, for example, a ro-ro boat.

For example, a vehicle carrier is equipped with several tiers of ``V'' inside the ship.
An inboard ramp system is provided between the upper and lower decks to communicate with each other.

The conventional lamp device l shown in FIGS. 1, 2, and 3 is
Two 7'c hand lamps 2L divided in parallel.

2R, and a food cover 3 arranged in series with the hand lamps 2L and 2R. Hand lamp 2L, 2
The proximal end portions 4 of B are rotatably hinged to the deck. The base end 5 of the entire inner cover 3 is rotatably hinged to the deck and rotates upward.

As shown in FIG. 1, when both the vents 2L and 2R and the food cover 3 are held in the closed position, the lamp opening 6 forms a flush plane with the upper deck 7 and extends over it. Allow vehicles etc. to pass.

As shown in FIG. The ramps in the hand that connect all the decks 80 are fully formed, while the 2 ramps in the hand and the food cover 3 are connected to the upper deck 7.
The entire area is on the same plane as the area, so that vehicles, etc. can pass through it. Therefore, cargo can be loaded onto the upper deck 7 and the lower deck 8 at the same time.

As shown in FIG. 3, when both the stroke vents 2L and 2B and the full inner cover 3 are held in the open position.

When the lamp opening 6 is fully opened, one half-width lamp 2L
, 2H form an eclipse ramp connecting the upper and lower decks 7.8. This allows larger vehicles to travel.

Incidentally, in the case of a small vehicle such as a passenger car, the slope angle of the ramp is allowed to be up to about 13 degrees, but in the case of a large vehicle such as a trailer, the suitable slope ratio of the ramp is 1:7 to 1:8. For this reason, the lengths of the half-rlJ lamps 2L and 2R needed to be long to match the large vehicle.

However, the enlargement of the above-mentioned Techurande 2L and 2R,
The strength of 2L and 2R themselves and the lamp opening 6
There was a problem that the strength of the hull in preparation for water tightness deteriorated when the system opened. In addition, increasing the size of the hand lamps 2L and 2R in the limited space inside the ship resulted in a reduction in the deck area, which caused the problem of reducing the loading space.

The present invention has been made by focusing on the above-mentioned problems.

The overall purpose is to miniaturize the inboard ramp device by making it possible to change the angle and running state of a ramp that communicates between upper and lower decks depending on the type of vehicle being run.

As shown in FIG.
For example, the proximal end portions 4 of two hand lands 2L and 2R, which are divided in parallel, are rotatably connected to the rotating tip portion 11 of the hand.

When this lamp device 1 is limited to small vehicles such as passenger cars and two lamp devices are moved in parallel between the upper and lower decks 7 and 8, as shown in Fig. Hold both stroke landes 2L and 2 in the open position and form a slightly steep slope during the eclipse.

When cargo is to be loaded onto the upper deck 7 and the lower deck 8 at the same time using the ramp device l, as shown in Fig. It forms the same plane and allows vehicles to travel on it. The other hand canopy 2L is held in the open position to form a slightly steep hand ramp completely connecting the upper and lower decks 7 and 8.

When a large vehicle such as a trailer is to be moved completely between the upper and lower decks 7 and 8, the middle ramp 9 is fully rotated as shown in FIG. The upper and lower decks 7.
During the eclipse, a gentle slope connecting the 8 areas is formed.

In addition, when loading and unloading only on the upper deck 7, the loading lamp 9 and both chuunzo 2L and 2R'! f Hold the lamp opening part 6 in the fully closed position. This forms the same plane as the upper deck 7, allowing the vehicle to travel.

More specifically, as shown in FIGS. 8 and 9, a hinge 12 is provided on the proximal end 10 of the eating landing 9 and is rotatably connected to the upper deck 7. Four hydraulic cylinders 13 are arranged in parallel on the lower surface of the eating unzo 9 to drive it. This hydraulic cylinder 13 has a base end 14 connected to the lower deck 8, and a rod tip 15 connected to the lower deck 9.
Connect to.

The hand lamps 2L and 2L have their base ends 4 connected to hinges 16.
It is rotatably connected to the rotating tip portion 11 of the eating runde 9. Two opening/closing link devices 17 are provided in parallel at the lower portions of the hand lamps 2L and 2R for abutting against and pushing up the lower surfaces 22 of each.

As shown in FIGS. 10 and 11, the opening/closing link device 17 includes a support link 20? f- Prepare. The support link 20 has its lower end 18 rotatably connected to the lower deck 8 through a shaft 19. At the upper end 21 of the support link 20, a hand lamp 2L and a roller 33 which abuts against the lower surface 22 of the two cylinders are rotatably attached and a block 24t is fixed. When the link 20 rotates to fully drive the lamps 2L and 2 in the hand, the above-mentioned row 223 touches the lamp lower surface 22'? i- It is designed to roll.

'A hydraulic cylinder 26 is provided for tilting and driving this support link 20. This hydraulic cylinder 26 has its base end 2
7 is connected to the lower deck 8, and its rod tip 28 is connected to the middle of the link 20.

A lipping block 30 is provided which slidingly engages the lower end 18 of the link 20. A hydraulic cylinder 31 is connected to the locking block 30, and the locking block 30 is engaged with and released from the link 20 by expanding and contracting the hydraulic cylinder 31.

When the opening/closing link device 17 holds the hand-operated containers 2L and 2 in the closed position as shown by the solid lines, the link 20 stands up vertically, and the link 20, the block 24, and the locking block 30 close the hand-operated containers. Fully supports the loads of 2L and 2R. Note that 33 is a stopper with which the roller 22 comes into contact.

On the other hand, the opening/closing link device 17 is the hand lamp 2L.

21% i When held at an angle as shown by the imaginary line,
With the hydraulic cylinder 26 contracted and the support link 20 tilted, the roller 23 is brought into contact with the lamp lower surface 22 to fully support the load.

That is, the opening/closing link device 17 has the function of fully driving the hand lamp 2L, and the hand lamp 2L.

It has the function of a support stay and bristles to support two containers in a fixed position.

As shown in Fig. 9, the full width run f9 and the hand run de 2L
, a flap 35 is provided at the joint between the two containers.

The flap 35 is rotatably connected to its proximal end 36' (l-tip part 11 of the eclipse lamp 9), and its distal end 37 abuts on the proximal ends 4 of the hand rande 2L, 2R.

As a result, as shown by the imaginary line, the lamp in hand 2L.

Even when 2R rotates around the entire center of the hinge 16, the flap 3
5 can keep the protrusion (intersection angle) formed by the connection between the distal end 11 and the proximal end 4 small.

In summary, the present invention provides a Kanayama lamp whose base end is rotatably connected to the hull, and a hand lamp divided into two or more parallel lamps at the rotating tip of this one lamp. Because they are movably connected, the angle of the ramp can be changed completely depending on the type of vehicle, and the inboard ramp device can be made smaller.

This makes it possible to increase the strength of the hull.

Moreover, there is an effect that it can greatly contribute to improving safety and efficiency during cargo handling.
