Abstract

PURPOSE:To make it possible to adjust the folding angle between a root panel and an intermediate panel, by forwardly extending both side sections of the root panel attached rotatably to a hull and, by suspending a wedge rotatably to the tip end of the root panel so that the inclination of the wedge may be adjusted. CONSTITUTION:Side beams 4 are laid on both forwardly extended sections of a root panel 1 coupled rotatably to a hull by means of a pivotal shaft 11. A wedge 20 is rotatably suspended to the tip end of the side beams 4 inside thereof. The inclined position of the wedge 20 is limited by a pin fitted in one of stopper holes 25 formed in the side beam 4. With this arrangement, the lower end of the wedge 20 abuts against the upper surface of an intermediate panel 2 so that the folding angle between the root panel 1 and the intermediate panel 2 may be adjusted by selecting the inclined position of the wedge 20, thereby the attaching level of the ramp may be suitably adjusted and held.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lamp device installed in a ro-ro boat or the like.

Conventionally, there is a type of ramp device that bends from the middle part, and for example, when the quay is -1- higher than the ship's hull, there is a base panel that is installed tilting in one direction from the ship's hull, and this base panel. It slopes downward from the tip to the quay for $8'? 1411 tail (Special FIA 11f (57-231268P3 <Reference number 58-92856)).

This lamp 4! ! When a vehicle or the like passes through the decoy (well, the angle at which the middle panel bends with respect to the base panel (hereinafter referred to as the middle bending angle) needs to be kept constant.

Conventionally, in order to maintain this bending angle [alpha], for example, a wedge sandwiched between both panels has been manually inserted.

However, it is necessary to prepare wedges of various shapes depending on the center bending angle, and this one wedge has the required strength to overcome the center point of the run/''IAieY. Because it is completely covered, its weight becomes large,
There was a tie for the manual operation of carrying the device.

In addition, there was a conventional model in which a hydraulic cylinder was installed between both panels to maintain the bending angle using hydraulic pressure, but this had a complicated structure. There was a problem with 2-.

The purpose of the present invention is to solve the problem described in item 1-1, and a 1-noid beam extending from both sides of the base panel toward the tip is provided (J). The wedge has a curved bottom surface that comes into contact with the middle panel.
When multiple stopper holes are formed and covered, a bottle is selectively inserted into the stopper hole and comes into contact with the side of the wedge to prevent the rotation of the T-shape, while the wedge is operated. What is the configuration for connecting ropes?

This allows you to adjust the degree of protrusion from the reed jamb via the 1st leg (Mabin and operation 1), and insert this 1st leg between the intermediate panel (JL 1: Beam) and the beam. Ngunchu 11ire//+Shogaho 1."+ (Saru J,)nikuta-=)'i is there.

Embodiments of the present invention are attached and explained based on the NJ drawings.

As shown in FIG. 1, the base panel 1 has its 44 end rotatably connected to the hull 5 via a hinge 11, and the intermediate panel 2 is connected to the base panel 1 via a hinge 12. It is rotatably connected, and the L
A grounding flap 3 is rotatably connected via a hinge 13.

Side beams 4 extending toward the tip are formed on both sides of the root panel 1, respectively. A pulley 14°15 is attached to the side beam 4 and the intermediate panel 2,
The pulleys 14 and 15 are connected to a winch on the hull (not shown) and rotated. Through this Y

As a result, the base panel 1) rotates around the hinge 11.

As shown in FIG. 2, a wedge 20 is rotatably lowered into the inside of the lead bee l\1 via a support 21.

-4- This one joint 20 has a shaft 21 at its tenth end with a rotating shaft 71 ← two supports 1.7 and a section 22 iiQ i-J, and the lower end has an arc-shaped cross section. A plurality of groove holes 25 are formed at predetermined intervals in an arc centered on the axis 21 on the inner surface 28 of the 1° wide beam 4 on which the curved bottom surface 23 is formed. .

It should be noted that the ridge 20 having the bottom surface 23 and side surfaces 27 as described above is integrally formed of metal and has a considerable degree of strength and protrusion.

At this time, turn the end of the wedge 20IJ operating rope 29 +L.
It is fastened to the fitting 31 and is held in a state where it does not protrude from the beam 4.

If the quay 6' is not at a sufficiently low position relative to the hinge part 11 of the hull 5, as shown by the two-dot chain line in FIG. 2 is tilted downward from the base panel 1, and the flap 3 is brought into contact with the quay wall 6'.

To move the lamp device from the stored state to the above-mentioned lamp state -6-, first remove one end of the operating rope 29 from the tightening fitting 31, and then set the wedge 20 free +;--.+

The height of the quay 6' changes relative to the water level and the condition of the cargo.
By inserting 4, the rotation angle of the wedge 20, that is, the amount of protrusion from the lead piece 1) 4 can be adjusted, and the folding angle of the intermediate panel 2 can be changed in stages and held.

Since the bottom surface 23 of the wedge 20 is formed in a curved shape, it can smoothly come into contact with the two-part surface 3 of the intermediate panel 2 in response to the angle fluctuation of the wedge 20.

As described above, the present invention (3L) has a rotatable middle stage on the id beam, and the amount of protrusion of the wedge can be adjusted via the bottle or operating rope inserted into the stopper hole. The effect of reducing manual operation and simplifying the structure is that it reduces costs by one.
