Are connected in the second section, and are bent only in a certain direction opposite to the guide plate above the second rod by the elongated hole and the guide piece and the guide plate below the first rod. And the third rod are connected at the third section and rotate freely, and the lower part of the third rod is pivotally mounted on the eye plate of the liftable car deck,
It is designed to freely rotate around the fourth section, and one of the linkages at the lowest point of the liftable car deck has a small angle with respect to the vertical line, and the other linkage is symmetrically supported. , The rotation stop pin built into the liftable car deck is projected with a hydraulic cylinder to stop the rotation of the third section of the linkage, the liftable car deck is supported at the intermediate position, and the lowermost point, the intermediate position and the uppermost It forms the car deck in the state.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1, 2 and 3, the present invention provides a liftable car deck 3 between a fixed deck 1 and a fixed deck 2.
It is composed of an elevating device for raising and lowering and a supporting device.

The liftable car deck 3 is provided with an elevating device, and a lifting cord 4 is provided at four corners of the liftable car deck 3.
Are pivoted, and are taken at jig winches 6 via pulleys 5 provided on the fixed deck 1 immediately above, respectively,
By the expansion and contraction of the cylinder of the jig winch 6, the liftable car deck 3 moves up and down at the lowest point, the middle position, and the highest position.

As an elevating device, a lift truck (not shown) is run on the lower fixed deck 2 and lifted to a predetermined clear height.
Is moved up and down with the lowermost point, the intermediate position and the uppermost part.

The liftable car deck 3 moves up and down between the fixed deck 1 and the fixed deck 2, and the following five types of clear heights can be secured during this time.

When the liftable car deck 3 is supported at the lowest point, the clear height CH1 and the clear height C
When H2 is secured and the liftable car deck 3 is supported at the intermediate position, the clear height CH3 and the clear height CH4 are secured, and when the liftable car deck 3 is supported at the top, the clear height CH5 is secured. It has become so.

When the liftable car deck 3 moves up and down, at least two guide posts 9 are provided on the outer plate 8 of the liftable car deck 3 on the ship side, and the guide posts 9 use hull ribs or the like. And a rail 10 stands on the guide post 9.

At least two support bases 11 are pivotally mounted on the ship side of the liftable car deck 3 corresponding to the rails 10, and front support bases 11 are provided with three-direction guide rollers 12 for positioning left, right and rear. Are provided so as to sandwich the rail 10, and a three-way guide roller 12 for positioning left and right forward is provided on the rear support base 11 so as to sandwich the rail 10.

In the vicinity of the hull center line 13, a four-section, three-bar linkage L is provided at least at two positions before and after the liftable car deck 3, which is hung on the fixed deck 1 to support the liftable car deck 3. ing.

On the ship side, the pin type hydraulic cylinders 14
Are built in the liftable car deck 3 and the pins are fitted into and removed from the recesses of the guide posts 9 to support the liftable car deck 3.

[0026]

Referring to FIGS. 4, 5 and 6, a liftable car deck 3 is provided between fixed decks 1 and 2, and is moved up and down by the elevating device.

The liftable car deck 3 shown in FIG. 4 has a linkage L at the lowest point where the liftable car deck 3 secures the clear heights CH1 and CH2 on the side of the hull center line 13 where no so-called guide post is provided. Supported.

The linkage L is composed of a four-bar, three-bar element. The first bar L1 of the first bar B1 is mounted on two eye plates E1 of the fixed deck 1 and is centered on the first bar L1. The first bar B1 and the second bar B2 are connected by a second node L2, and the slot 17 and the guide piece 18 and the guide plate below the first bar B1 are freely rotated. 15, the guide plate 1 above the second bar B2
5 to be bent only in a certain direction opposite to the direction of FIG. The second bar B2 and the third bar B3 are connected at a third node L3, and can freely rotate. The lower part of the third bar B3 has two eye plates E of the liftable car deck 3.
3 and pivots freely around the fourth node L4, and supports the liftable car deck 3 at the lowest point.

When the liftable car deck 3 is supported at the lowest point, one linkage L has a small angle α with respect to the vertical line 16, and the other linkage L is a symmetrical pair.

The liftable car deck 3 shown in FIG. 5 is raised by a lifting device and supported at an intermediate point by a linkage L. Only the third node of the linkage L is rotated so that the third bar is bent, and the first bar B1 and the second bar B2 are positioned on the vertical line 16.

When the liftable car deck 3 is lifted by the lifting device, the suspended linkage L is loosened, has a small angle α shown in FIG. 4, and the linkage L tries to return to the vertical line by gravity. L3 starts rotating and the third bar B3 is bent.

When the liftable car deck 3 reaches an intermediate position for securing the clear heights CH3 and CH4, the third section L3 of the linkage L is adjusted to be on the vertical line 16, and is incorporated in the liftable car deck 3. (See FIG. 3 for details.) A rotation stop pin 19 is projected by a hydraulic cylinder 20, so that the rotation of the third node L3 of the linkage L is stopped and the liftable car deck 3 is supported at an intermediate position. It has become.

The liftable car deck 3 shown in FIG. 6 is raised to the uppermost position by a lifting / lowering device so as to have a clear height CH.
5 shows a state in which the linkage L is secured.
From the state shown in FIG. 5, the rotation stop pin 19 is stored by the hydraulic cylinder 20, and all the nodes L1, L2, L3, and L4 are rotated, and are folded to the minimum length. In this case, the linkage L itself is not supported,
The hook 21, the pin 22, and the hydraulic cylinder 23 are separately hooked and supported.

[0034]

Since the present invention is configured as described above, the following effects can be obtained. The present invention does not provide a center guide post near the center of the hull, but provides a four-section, three-bar linkage, which improves traffic in large ships such as large vehicles, improves cargo handling efficiency, and improves the liftable car deck. Since it is supported by the linkage at the intermediate position and forms various kinds of clear heights, it is possible to cope with recent diversification of vehicle height and to achieve efficient loading.
