Abstract

PURPOSE:To decrease the refraction angle per fulcrum and expand the usable range of a ramp without affecting the car passage by dividing the first panel of an outboard ramp into the hull side and the quay side and rotataby connecting them within a predetermined range. CONSTITUTION:The first panel 1 of an outboard ramp is divided into a panel A on the hull side and a panel B on the quay side, and they are rotatably connected within a predetermined range at a fulcrum 7. Then, the panel A is not rotated by a fixed amount or more due to a stopper 6, and the refraction angle of the fulcrum 7 is kept at a fixed amount or less by the stopper. Therefore, since the panel B is inclined to the maximum limit of the inclination angle at any position in the upper and lower limits of a hatch 4 allowing the use of the ramp, the ramp can cope with the difference in level between the hatch 4 and quay in a wide range. The refraction angle per fulcrum is decreased, the panel refraction at the fulcrum does not affect the car passage, and the usable range of the ramp is expanded.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention is useful for loading vehicles on automatic JTT carriers, etc.
Concerning improvements to outboard lamps used for filtering.

(Japanese technology) Car carriers are generally equipped with an external ramp for running vehicles.
When berthing, this outboard ramp is passed between the rudder port on the side of the ship and the quay to load and unload vehicles. For example such as an outboard lamp! There are foldable ones like the YSIO diagram. This is done by attaching the base end of the first panel 41 freely to the fulcrum 3 provided at the end of the downwardly inclined part 4A formed in the rudder port 4, and further attaching it to the support 5 10 provided at the tip of the first panel. The second panel 42 has seven wraps 16 connected to a fulcrum 17 provided at the tip of the second panel 42 so as to be freely rotatable. During navigation, these panels 41 and 42 and the 7th panel 16 are folded into an upright state, and when berthing, the first panel 41 and the 12th panel 42 are connected to the wires 19 and 21 by a winch and a hydraulic sill 22 on the ship (not shown), respectively. Rotate through the f52 panel 42
Seven laps 16 at the tip of the ship are placed on the quay to connect the hull 2 and the quay. At this time, the first panel 41 and the second panel 42
The angle of refraction with respect to the beam is adjusted by an adjustment device (not shown).

Furthermore, there is also a vehicle in which an intermediate flap is provided at the joint between the first panel 41 and the second panel 42 so that the vehicle can run smoothly (Utility Model Publication No. 58-92856).

By the way, the relative height of the ship at anchor to the quay is not constant due to fluctuations in the tide level, changes in the watering method due to the amount of planted cargo, or differences in the quay to which it approaches. The rotation angle is changed to correspond to the change in head between the rudder port 4 and the quay. However, depending on the height, the slope of the panels 41 and 42 may exceed the mounting capacity of passing vehicles, or the slopes of the panels 41 and 42 may exceed the pitching capacity of passing vehicles. The refraction angle of any one of the lamps and 17 becomes large, causing problems such as a part of the lamp interfering with the vehicle body, which impedes the passage of vehicles. Therefore, in order to allow vehicles to pass smoothly, for example, the slope of the panel should be increased by 1
The refraction angle is limited to 3° or less, and the refraction angle is limited to 6.5° or less, which also determines the usable head range of the lamp. That is, in the case of this lamp, Fig. 11 is the upper limit position of the rudder port 4 with respect to the quay wall, and Fig. 12 is the lower limit position, and the lamp cannot be used unless the head difference between the rudder port 4 and the quay wall is within this range. Assuming the dimensions of the lamp are as shown, the usable head range of this lamp with a total length of 29+o is approximately 5.2τ0.

(Problem that the invention seeks to solve) In this case,! II', Fig. 1.1 (At the upper limit position of the rudder port 4 shown, the inclination of panels 41 and 42, the supports, α3 and 17
Both the refraction angles are the limit values. On the other hand, @12
At the lower limit position in the figure, since the inclined portion 4A is inclined downward, the refraction angle of the support 3 reaches the limit value even though the ff1l panel 41 is horizontal. In other words,
This lamp cannot be used by rotating the panels 41 and 42 above the bottom surface 5, so there is a problem that the range of head that can be accommodated is narrow.

On the other hand, as shown in FIG. 13 and FIG.
There are also lamps that form 0. In this case, since the bottom surface 5 is horizontal, the tip of the first panel 41 can be rotated slightly above the bottom surface 5 of the rudder port 4, and the lower limit position of the rudder port 4 where the lamp can be used is slightly lower. , at the same time, the upper limit position is lowered, and the range of head that can be accommodated is the total length 2 with the dimensions shown.
It is about 5.3m compared to 9m, which is almost the same.

SUMMARY OF THE INVENTION In view of the above-mentioned problems with the outboard ramp, it is an object of the present invention to provide an outboard ramp that can accommodate a wider range of head differences between the hull and the quay.

(Means for Solving the Problems) Invention 1 includes an fjS1 panel that rotates around a base end attached to the hull, and a second panel that is rotatably connected to the tip of the PJS1 panel. In the outboard ramp that connects the hull and the quay, the first panel is divided into panel A on the base end side and panel width on the tip side, and these panels A and B
A stopper is provided to connect the two rotatably and freely to rotate, and to restrict this rotation within a predetermined angular range.

(Function) Since panel B of the p51 panel is connected to the hull via panel A, the angle of inclination of panel B with respect to the hull is equal to that of panel A.
This is the sum of the refraction angles at the two rotation supports at both ends of -k, and the refraction angle at each support point can be kept small relative to the inclination of panel B, so it is possible to use the lamp with panel B tilted significantly. can.

(Example) Embodiments of the present invention are shown in FIGS. 1 to 9.

It consists of a connected proximal panel A and a distal panel B. Panel A is constructed using a fulcrum 3 provided on one side of the hull 2.
It is rotatably connected to the substantially horizontal bottom surface 5 of the rudder port 4. A stopper 6 is fixed to the hull 2 so that the panel A is not bent beyond a certain level with respect to the bottom surface 5 when the lamp is used. Panels A and B are rotatably connected at a fulcrum 7, and stoppers 8 and 9 as shown in FIG. A fulcrum 10 is provided at the tip of the panel B, to which a second panel 11 is freely rotatably connected. The refraction angle between the first panel 1 and the second panel 11 is adjusted by an adjustment device (not shown) as in the conventional example. Further, an intermediate flap 12 is provided above the fulcrum 10. The intermediate flap 12 is rotatably attached to a hinge 13 provided on the panel B as shown in FIG.
2 is supported in the cutout 14 of the second panel 11. There is a fixed angle gis in the middle of the second panel 11 that is slightly bent downward.
is formed, and seven wraps 17 are rotatably attached to a fulcrum 16 provided at the tip.

The first panel 1 is a pulley 1 attached to the side of the tip of panel B.
The hook 8 is raised and lowered by a winch (not shown) on board the ship through a turned wire 19. Further, the F52 panel 11 is rotated about the fulcrum 10 by the expansion and contraction of a hydraulic sill 22 on the ship through a wire 21 hooked to a pulley 20 attached to the side and rotated.

In order to lead the wire 21 to the hydraulic ring 22, slots 2:3 and 24 are provided on the side of the first panel 1.

Further, in order to guide the wires 19 and 21 to predetermined positions on the ship, pulleys 25 are provided at important points on the ship's hull side.

Next, the action will be explained.

While the ship is sailing, the outboard lamp is housed on the side of the ship's hull 2 in an upright position as shown in FIG. Then, when docked at the quay, by operating the winch and hydraulic sill 22,
The lamp is laid down by rotating the first panel 1 and the second panel 11, but at this time, panel A is prevented from rotating beyond a certain level by the stopper 6, and the bending angle of the fulcrum 7 connecting panels A and B is is always kept below a certain level by the action of stoppers 8 and 9. Note that the refraction angle of the f51 panel 1 and the f52 panel 11 at the fulcrum 1 () is adjusted by an adjusting device.

The use of lamps is directly arranged.As with the conventional example, the angle of inclination of the panel is 13.
If the refraction angle between the panels is limited to within 6.5°, the upper limit position of the rudder port 4 where this lamp can be used is shown in Figure 5.
The lower limit position is as shown in FIG. In this case, panel B of fjS1 panel 1 is tilted to the full tilt angle limit at either the upper or lower limit position, so the lamp is at the rudder port 4.
It can accommodate a wide range of differences in the level of the quay.

In other words, if the dimensions of each part of the ramp are as shown in Figures 5 and 6, even though the total length of the ramp is 29 m, which is the same as the conventional example, the range of the head difference between the rudder port 4 and the quay that can be accommodated by the ramp is limited. is approximately 7.2 m, which is significantly increased compared to the conventional example. Furthermore, the ramp can be used even if the rudder port 4 is located at a lower position than the quay.

In addition, instead of the stopper 6 that restricts the rotation of panel A, as shown in FIG. They may be connected by foldable links or collapsible links. Furthermore, if the panels are connected by hydraulic sills instead of these links, the rotation angle of the panel A when it is collapsed can be adjusted as desired.

In addition, the stopper 8 provided between the panel A and the snake is formed by forming an arm 8A and a protrusion 8B on the side surfaces of the panels A and B, respectively, as shown in FIGS. The structure may be such that when the arm 8A rotates iF and Z, the arm 8A comes into contact with the protrusion 8B to prevent rotation beyond a certain level.

(Effects of the Invention) As described above, in the present invention, the fjS1 panel of the outboard ramp is divided into panel A on the hull side and panel side on the quay side, which are rotatably connected to each other within a predetermined range. It is connected to the hull via two supporting points, and the bending angle per supporting point α becomes small with respect to the inclination of panel B. Therefore, even if panel B is greatly tilted to near the limit of passage of jμ cars, the refractive power of the panel at the support and v will not hinder the passage of 11 cars, and the usable range of the lamp will be expanded.

In addition, the permissible range for the height of the lamp installation on the hull has been widened, increasing the degree of freedom in hull design, and when using within a certain head range, the length of the lamp can be shortened compared to conventional lamps. Weight can be reduced and costs can also be saved.
