Description

[Detailed explanation of the idea] This invention relates to a movable deck device for a warehouse rampway.
It is.

For example, as shown in Figure 1, a car ferry has two vehicle decks: a lower deck 1 and an upper deck 2.
When installing a warehouse rampway 3 with a see-saw set that allows the direction of vehicle transfer between the warehouses to be freely controlled, a front flap 4 and a rear flap 5 that can be connected to the front and rear of the warehouse rampway 3 are installed on the lower deck 1. It becomes necessary.

With such a configuration, for example, as shown in FIG. 2, when the vehicle 6 is boarded from the lower deck 1 to the upper deck 2 using the rear flap 5 and the hold ramp way 3, both of these 5, 3
The vehicle 6 located above becomes tilted (in an ascending state).

Therefore, in order to prevent the upper part of the vehicle 6 from contacting (colliding) with the upper deck end (connection part) 2A located above the rear flap 5, the vehicle passing height between the virtual slope 7 and the lower end of the upper deck end 2A is adjusted. A must be determined.

The deck height L between the rainboards 1 and 2 is generally determined by the vehicle passing height A mentioned above. Therefore, a space S larger than necessary for the vehicle height H is created. This waste of space causes problems such as uneconomical costs due to an increase in the amount of steel used.

The present invention proposes a movable deck device for warehouse rampways that can solve the above-mentioned problems.
This will be explained based on FIGS.

That is, the present invention is provided with a warehouse rampway 12 that can communicate between the upper deck 10 and the lower deck 11 and that covers a part of the upper deck 10.

The upper deck end 10A, which is located above the flap 13 provided at the connection between the warehouse rampway 12 and the lower deck 11 and connectable to the warehouse rampway 12, is connected to the upper deck 10 via the hinge mechanism 14. By attaching it to the upper deck 10 and receiving the lower surface of the upper deck end 10A with a stopper body 15 connected from the upper deck 10 (it is also possible to support it with a chain or a hanging link), it is possible to connect to the warehouse rampway 12. and a position above this position.

Further, an interlocking device 16 is provided for the upward movement of the upper deck end 10A and the connection movement of the hold rampway 12 to the lower deck 11.

This interlocking device 16 has a pair of left and right wires 17a, 17b, one end of which is fixed to both ends of the upper deck end 10A, and guides these wires 17a, 17b, and moves the other wire 17b toward one wire 17a. A plurality of fixed sheaves 19a and 19b are attached to the ceiling wall 18, a movable plate 20 to which the other ends of both wires 17a and 17b are fixed, and a guide that guides the movable plate 20 up and down and is attached to the lower deck 11. 21, a guide roller 22 attached to a suitable position on the movable plate 20, and a protrusion that protrudes laterally from the end of the warehouse rampway 12 and can come into contact with the guide plate 21 through a slit 23 formed in the guide 21. It consists of a rod 24.

Normally, the upper deck end 10A is supported by the stopper body 15 in a horizontal position, as shown by the imaginary line in FIG. 3 and the solid line in FIGS. 4 and 5, and the warehouse rampway 12 is As shown by solid lines in FIGS. 4 and 6, it is connected to the upper deck end 10A.

Therefore, it is also possible to load the vehicle 25 onto the upper deck end 10A.

When transferring the vehicle 25, the warehouse rampway 12 is moved downward by the operation of a drive device (not shown).

Then, before the warehouse rampway 12 lands on the lower deck 11, the protruding rod 24 passes through the slit 23, enters the guide 21, and comes into contact with the upper surface of the movable plate 20.

Therefore, the movable plate 20 is pushed down by the subsequent downward movement of the warehouse rampway 12, and the wires 17a and 17b are pulled down accordingly.

Due to the movement of the wires 17a and 17b, the upper deck end 10A swings upward via the hinge mechanism 14, thereby opening the warehouse rampway 12 as shown by the solid line in FIG. 3 and the phantom line in FIG. When connected to the flap 13, the upper deck end 10A swings upwards sufficiently, thereby causing the flap 1
This will create a large space above 3.

As shown in FIG. 3, this means that the vehicle 25 can be transferred safely even though the deck height l is lowered and the space S is reduced.

9 and 10 show another embodiment of the interlocking device 16. FIG.

That is, a pair of left and right wires 17a, 17b, one end of which is fixed to the end of the warehouse rampway 12, is connected to a plurality of fixed sheaves 19a, 19b and a plurality of movable sheaves 26a, 26b. After winding it several times,
The other end is fixed to the ceiling wall 18 side.

The movable sheaves 26 a and 26 b are connected to the upper deck end 10 by connecting wires 27 a and 27 b.

According to this, the upper deck end 10 moves upward simultaneously with the downward movement of the warehouse rampway 12, but the stroke is such that the two wires 17a, 17b are wound multiple times between the two sheaves 19a, 26a, 19b, 26b. By doing so, the upward movement of the upper deck end portion 10 becomes smaller.

FIG. 11 shows another embodiment in which the upper deck end 10A is moved up and down in a lifting manner, and this case is also similar to the previous embodiment.

In the above embodiment, the warehouse rampway 12 is shown swinging on one side, but a similar effect can be expected in the warehouse rampway 12 of the seesaw set shown in the conventional example (FIG. 1).

According to the present invention described above, when transferring a vehicle between the upper deck and the lower deck, the running of the vehicle at the connection between the lower deck and the warehouse rampway is moved upward from the end of the upper deck. With a simple configuration and operation, it can be done safely without contact (collision).
Moreover, the height between the panels during rain is slightly higher than the height of the vehicle, minimizing unnecessary space, and economical effects can be expected by reducing the amount of steel used.

In particular, according to the present invention, the upward movement of the upper deck end can be automatically performed by moving the hold rampway downward, thereby eliminating the need for an upward movement operation and completely eliminating malfunctions.
