Abstract

PURPOSE:To utilize the captioned device as ramp and as elevation lifter when a door is opened, by installing a basic board in free elevation inside an opening on the ship side and installing platform in tiltable ways onto the base board and closing the opening watertightly. CONSTITUTION:An elevation base board 7 is installed inside a ship-side opening 2 through a wire, etc. A platform 3 is installed in tiltable and swingable ways onto said base board 7 through a hydraulic cylinder mechanism 11, link 9, etc. The platform 3 swings in standing state, and the opening 2 can be closed water- tightly. Therefore, the captioned apparatus can be utilized as ramp by swinging the platform 3 at a horizontal position, and also can be utilized as elevation lifter by raising and lowering the elevation base board 7.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening door, and more specifically, to an outer panel of a ship.
This invention relates to a door for an opening that not only watertightly closes an opening cut in a panel such as a bulkhead, but also is made horizontal when the door is opened and is used as a table for loading cargo on the top surface and as a lifter for raising and lowering cargo.

On the outer skin of the hull? If a cargo table or cargo lifter is installed adjacent to the lower end level of the opening to relay cargo between the inboard forklift and the quay-side forklift when openings such as hanging side hoards are opened. It is thought that this will help improve the efficiency of cargo handling when berthed.

The purpose of the present invention is to serve not only as a door for closing an opening cut in a panel such as a hull shell or a bulkhead, but also as a table and linter that releases cargo between the inside of the ship and the shore side when the door is opened. The purpose is to obtain a useful opening door.

According to the present invention, the receiving frame is formed into a rectangular shape that is bored into a panel such as an outer panel or a partition wall, and is tapered so that the alignment portions on both sides are expanded upward, and is attached to the alignment portions on both sides and the bottom edge. It is a wedge-shaped plate-shaped door that is fitted from above the opening provided with the door, and is installed movably up and down on one side of the panel adjacent to the lower end of the receiving frame, and has a width that is approximately the same as the narrow end of the door. a horizontal platform having a generally rectangular shape and having one end hingedly connected to the end; a lifter for raising the platform flush with the bottom edge of the receiving frame when the door is closed; In some cases, the height frame is rotatably mounted at one end and, in some cases, is equipped with a drive lever mounted at the opposite end with a wheel that rotates along a track mounted on the surface of the door at right angles to the bottom edge of the receiving frame. A door with an opening that corresponds to the following is obtained.

Now, an embodiment of the apparatus of the present invention will be described below with reference to the accompanying drawings.

Referring to Figure 1, there is a model flat door body 3 that closes an opening 2 drilled in a vertical panel IK of a ship's hull, bulkhead, etc.
The horizontal V device is removed from the opening 2 and is placed in a condition where it is used as a cargo table and lifter for loading cargo onto the top surface.

The door device IO of the present invention includes a door body 3 and a lifter 7 having a horizontal platform 20 which is rotatably connected to a narrow armor portion (left end in the figure) of the door body 3 via a hinge fitting 8. One end of the frame 131C of a predetermined height attached to the left end of the lifter is rotatably attached to a wheel 19 that rolls along a track 17 attached to the surface of the door body 3 at right angles to the lower edge of the opening 2. The opposite end is provided with a drive lever 9 with several levers.

, as shown in Figure J-4, the opening 2 has a rectangular shape with the left and right lined portions tapering upward, and the bottom edge of the opening 2 and the left and right lined portions are VC-shaped. It is equipped with a U-shaped receiving frame 4. The door body 3 is a wedge-shaped flat box panel having dimensions slightly smaller than the dimensions of the opening 20, and its outer peripheral portion faces the receiving frame 4 of the opening. On the inner periphery of the receiving frame, there is a gasket 5 that is pressed against the outer periphery of the door body 3.
It is equipped with

The height H of the opening 2 is made much higher than the height of the door body 3. Therefore, as shown in Figure 'A13, the door body 3
is placed in the closed position VC, the upper end of the door body 3 and the opening 2
A recess 22 with a height k is formed between the upper end of the recess 22 and the upper end of the recess. A door stopper 6 hangs down from the panel 1 at a predetermined distance d from the inner surface (left side surface) of the door body 3 in the closed position and closes the recess 22. A gasket 5 is attached to the surface of the door stop material 60 adjacent to the upper edge of the door body 3 and pressed against the left surface. 24 indicates a gasket support material. The door body 3 placed in the horizontal position (1) in Figure 1 is raised by a predetermined amount by the elevator 7, and then raised to the upright position (II) by the drive lever 9.
It is brought to a position where the upper end 3T is opposed to the upper end 22TK of the concave Ffr22. By placing the door body 31 above the opening 2 by the height k, the door body 3 can be moved into the U-shaped receiving frame 4 without causing the edges on both sides of the door body 30 to collide with the edges on both sides of the opening 20. It can be placed in the recessed part of. Therefore, when the door body 3 is lowered by the elevator 7, the jb body 3 can be placed in the closed position.

As shown in Figure 1.1, the lifter 7 is provided with a horizontal platform 2o that is placed flush with the door body 3 when the door body 3 is placed in a horizontal position.

The horizontal blanket form 20 has the same width as the door body 3 and is hinged to the door body 3 by a metal fitting 8.

Frame work 3 of a predetermined height is provided on the left side of both ends of the horizontal platform 200 in the width direction. Each frame 13 holds a vertically attached plate-shaped guide member 12, and a pair of rollers 14A rolls along each guide member 12.
, 14B.

A wire 15 led from a drive winch 16 for raising and lowering the beam lid 7 is connected to the upper end of each frame 13.

Place the door body 3 in the closed position (when horizontal platform 2
0 at the level of the lower end 2B of the opening 2, a pin 21 is provided on the left side of the lower end of the panel.

When the water sprayer 3 is used as a lifter, it can be raised and lowered to the position 3' with the door 3 opened horizontally. This is effective when dealing with the relationship between the ship's stagnation and the quay (such as when cargo is reduced on one side) and constant displacement.

A drive lever 9, one end of which is rotatably connected to the upper end of each frame 13, has a wheel 1' 9 attached to the opposite end, which rolls along a track 17 set on the inside at right angles to the left end of the door body 3. ing. The middle part 9 of the length of each drive lever 9 at the working end 2
A hydraulic cylinder 11 to which 3 is connected has its lower end rotatably attached to a horizontal platform 20Vc.

The door body 3, which is in the closed position with the above configuration, has its lower end connected to the horizontal flat form 20 and its upper end! Since the contacting parts are connected to the drive levers 9 on both sides, it is held in place, but if necessary, a tightening mechanism such as a cleat or a dock can be placed on the outer periphery of the door body. . Further, the recess 22 of the opening 2 can be provided with a locking mechanism for holding the door body 3 in a watertight closed position.

As described above, according to the present invention, the vertical door 3 that closes the opening 2 in the outer panel, bulkhead, etc. is held horizontally in the area adjacent to the lower end of the opening and used as a table and lifter for loading cargo. Can be done.

Cargo loaded onto table 3VC by a forklift onboard the ship can be easily transferred to a forklift on the shore side, or can be transferred to VC using the reverse procedure.
