Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides a car carrier in which a slope is provided between a deck on which cars board and each deck where cars are stored, and the slope is connected to the rear side of the deck. This device relates to a slope device that can be moved up and down via a link mechanism that can be folded to the side, and the slope is held tilted and used as a vehicle running path, especially when loading a car.
On the other hand, when the slope is not in use, it is raised so that the lower side of the slope can be used as a storage space for automobiles.

[Conventional technology]

On car carriers, a slope is installed from the deck where cars board to the storage deck for vehicles inside the ship, and cars are loaded onto each deck like a multi-story parking lot, but if this slope is left as is, Cars cannot be stored below the slope. Therefore, the storage space for vehicles on the ship as a whole will be reduced, so the ramp will be made movable so that it can be raised and lowered, so that when necessary (when not in use) it can be lifted and cars can be loaded onto the bottom of the ramp. I needed to.

For this reason, various ramp devices have been proposed and used in the past in order to meet such demands, but these devices have the following problems, and improvements have been desired. That is, in the conventional type shown in FIGS. 10A and 10B, the slope S is suspended by a wire W from the upper deck, and the slope is raised and lowered by letting out or pulling this wire W through a jigger cylinder J. However, when installing this device, it is extremely troublesome to position the wires and jigger cylinder, and alignment is often required on-site, but since the adjustment point is behind the ceiling, the work is difficult and labor-intensive. The work environment is also poor because the work area is a closed space. Furthermore, since a large amount of wire is used, the amount of processing work for the wire ends increases, and there is also a restriction that the wire must be replaced at regular intervals.

In addition, the conventional type shown in FIGS. 11A and 11B is a lifter type device, and this device has a base B fixed to the bottom of a platform P that serves as a slope.
A side L ₁ is provided between both ends of this base and the platform, which is driven by a cylinder C ₁ and can be raised and lowered, and a leg L ₂ which is also driven by a cylinder C ₂ and can be folded in two.
The platform P has a complicated structure, and the upper part of the platform P is difficult to use as an automobile storage space. That is, when the upper part of the platform is used as a storage space, the platform must be manufactured so as to be embedded in the lower deck, and therefore the manufacturing cost must be increased.

Furthermore, the first device with a structure similar to the device of the present invention is
An elevating and lowering support device for a movable slope as shown in FIG. 2 has also been proposed.

[Problem that the invention seeks to solve]

However, when this device raises the slope main body S, the rod end E extending from the cylinder _C3 serving as a support leg is fitted into a pot-shaped receiving hole F provided in the lower deck to raise the slope. In this device, cylinder _C3 receives the reaction force of the slope, so cylinder _C3 is easily damaged by the bending moment, and if damaged, the rod will no longer be able to move, and a pot-shaped hole F must be provided in the lower deck. Must be. Furthermore, in order to retract cylinder _C3 to the back of the slope, a separate auxiliary cylinder is installed.
It required _C4 and had drawbacks such as high production costs.

[Means for solving problems]

Here, the present invention improves all the drawbacks of the various slope devices as described above. In other words, the present invention allows the link to be raised and lowered using only one cylinder device, resulting in a simple structure that does not require any special auxiliary equipment, and also eliminates the need to dig into the lower deck, which serves as the operating fulcrum, when raising the slope. ,
Furthermore, when the slope is raised, the cylinder is prevented from being damaged by the action reaction force, and the cylinder size can also be reduced.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings. Figure 1 shows an example in which this device is installed between the boarding deck and the upper deck of a car carrier. In the figure, reference numeral 1 designates an upper deck for storing vehicles, 2 a lower deck serving as a vehicle boarding deck, and 3 a slope connected to the upper deck by a hinge member (not shown). The main body of the slope 3 is partially opened on the back side, and a hydraulic drive cylinder 4, for example, is disposed inside the main body, and the tail end of this cylinder is fixed to the main body of the slope. A roller support shaft 6 is fixed to the end of the cylinder rod 5 so as to be perpendicular to the rod 5, and horizontal rollers 7 are attached to both ends of the shaft as shown in FIG.
Attach 7 so that it can rotate freely. This horizontal roller 7 is inserted into guide rails 8, 8, which are guide members for the rod 5 fixedly installed on the lower surface of the slope 3, and is provided so that the roller 7 can run inside thereof while rotating in contact with the cylinder. Prevents rod bending and damage. As shown in FIG.
A link 9 is rotatably mounted, and a wheel or roller 10 is provided at the end of the first link so as to abut against the lower deck. This first
For link 9, there is a short second link 1 in the middle.
1 is rotatably attached in a substantially Y-shape, and the tip of the second link 11 is rotatably attached closer to the tip of the slope 3 than the end of the cylinder rod 5. Further, among the Y-shaped links 9 and 11 attached to the tip of the cylinder, a guide and locking member 12 for folding the link when storing the link is provided on the lower surface side of the first link 9. For example, this member has a semicylindrical cross section and is fixed to the back side of the slope 3. In addition, the reference numeral 13 is a wedge cylinder attached to the tip and both side edges of the slope 3, and as shown in the figure, the cylinder rod is engaged with the upper deck 1 and the slope 3 is lifted so as to be flush with the upper deck. It fixes it. Incidentally, FIG. 3 shows a state in which the slope 3 is lifted and held on the upper deck 1.

In the device of the present invention configured as described above,
When the slope 3 is tilted to lower the lower deck 2, the cylinder rod 5 of the drive cylinder 4 is first extended, as shown in the operational diagram of FIG. By doing this, as the rod 5 extends, the first
The end roller 10 side of the link 9 descends, and the second link 11 expands in a Y-shape with respect to the first link 9, as shown in FIGS. 4 and 6 (). When the end roller 10 of the first link 9 comes into contact with the lower deck 2, the wedge cylinder 13 is operated to release the engagement between the cylinder rod and the upper deck, and the cylinder rod 5 is contracted, as shown in FIG. The slope main body 3 is lowered as shown in parentheses so that the flap 14 at the tip of the slope comes into contact with the lower deck, and the slope 3 is set at an angle that allows the automobile to run. On the other hand, when lifting the slope 3 from the lower deck 2 and storing it on the upper deck 1, the operation is reversed to when lowering it. That is, first, the rod of the drive cylinder 4 is extended as shown in FIG. 6(). In this way, the thrust of the cylinder 4 is transmitted to the end roller 10 via the first link 9, and as a result of this roller 10 receiving a reaction force from the lower deck 2, the slope 3 rises about its end hinge. Then, as shown in Figures 4 and 6 (), the slope 3 rises to the same level as the upper deck 1, so at that time the wedge cylinder 13 is operated to engage the cylinder rod with the upper deck 1 and fix the slope 3. do. Then, when the rod 5 is operated to contract against the drive cylinder 4,
The first link 9 is regulated by the second link 11, and the entire link is folded as shown in FIGS. 1 and 3, and is contracted into the opening on the back side of the slope main body. In addition, in FIG. 1, the reference numeral 15 is a reinforcing plate for the lower deck.

7 and 8 show a modification of the device of the present invention. In this example, the guide rail 16 of the cylinder rod 5 is attached to the back of the slope body 3, and the cylinder rod 5 is attached from this guide rail via a hanging fitting 17. It is designed to hold.

In addition, FIG. 9 shows a slope main body composed of a plurality of narrow panels 3a, 3b... divided in the width direction,
On the back side of each narrow panel, a first cylinder connected in a Y-shape driven by a cylinder 4 as in the previous embodiment is provided.
This is an example in which the link 9 and the second link 11 are incorporated. Even with this configuration, when the slope 3 is raised, the drive cylinder and the first and second links are stored in the rear part of the slope, so that a storage space can be secured under the slope, and the vehicle travels during cargo handling. Even in the event of a crash, there are no obstacles such as pots formed on the lower deck, making it easy for cars to get on board.

〔Effect of the invention〕

As mentioned above, the present invention allows a movable slope to be connected to one cylinder and one Y without using any hanging wires.
It is designed to be able to be moved up and down using only a linkage device, especially when the slope is not in use (when stored).
When folding the link into the back part of the slope, this can be folded without requiring any special auxiliary equipment. In addition, it eliminates the need to dig into the lower deck unlike conventional equipment, which eliminates the need for construction work when installing a slope, and eliminates obstacles when getting into a car, making it extremely easy to get into the car. In addition, this device has a structure in which the operating force when the slope rises is not directly received by the cylinder rod, but is received by the link, so there is less risk of cylinder damage, the cylinder size can be reduced, and the drive force is The cylinder and the link do not protrude from the slope, thereby providing industrial effects such as not inconveniencing the running of the automobile.
