Abstract

PURPOSE:To provide a simple floating dock by arranging two ships in parallel to utilize their buoyancy. CONSTITUTION:Two ships 1 fixedly interconnected with a girder 2 are provided in the outside holds with water tanks 3 into and from which is poured and discharged water to verticaly move the whole dock while providing a function of maintaining balance when ships or the like enter the central dock portion to apply a load to the dock. A working bed 7 is mounted in the interior of the girder 2 if necessary. Water proof doors 5 provided in the front and rear portions of this dock are mounted on the girder 2 or the working bed 7. This dock is made a dry one by closing the water proof door 5 to discharge water in the interior.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a simple floating dock that utilizes the buoyancy of two ships arranged in parallel.

Conventional floating docks were concave and expensive to construct, but
Since the present invention uses a boat, it can be self-propelled, and second-hand boats can be used, so it can be constructed at low cost.Also, it can function as a floating dock by simply attaching a girder and attaching a steel plate to the bottom of the girder. It is easy to construct.

Also, the front and rear sides can be opened and closed - it can be used as a dry dock by coughing and draining the water inside.

Furthermore, by creating a workbench parallel to the bottom surface and moving it up and down, it is possible to lift the workbench out of the water.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 4, il+ is two existing ships -, and both ships are connected and fixed by the girder (2).

A water tank (3) is installed in the outer hold of both ships that are connected and fixed, and by injecting or draining water, the entire dock can be raised and lowered, and if a ship or other object enters the central dock area and a load is applied. It functions to maintain balance.

Figure 1 (4) shows a working crane, and an appropriate number of them will be installed on board the ship as necessary.

The bottom part of the girder, shown in Figure 2 (6-), is covered with iron plates to prevent water from corroding the girder.

Further, on the ceiling of the girder, an appropriate number of lanes for running as shown in FIGS. 2 and 8 (8) are installed on the rails (9) as necessary.

Figure 2 (7) is a workbench, which is installed inside the girder (2) as required and constructed so that it can be moved up and down along the girder (2) using a hydraulic press or the like. This will lift the workbench out of the water.

FIG. 1 (6) shows waterproof doors that are installed at the front and rear of the dock as required, and these are attached to the girders (2) and (61) or the workbench (7).

By closing this waterproof door and draining the water inside, this dock can be used as a dry dock.

A normal ship's deck is convex, but a horizontal working deck can be built above the deck to allow work to be done on the deck.

The girder of this dock does not require special strength when the vessel is small and there are few waves, but when using a heavy vessel, when there is a wide distance between the two vessels, or when this dock is placed in the open sea with high waves. etc., it must be thrown with a structure of considerable strength.

In order to obtain strength, it is necessary to directly fix the girder to the keel of the ship by penetrating the belly of the il+ as shown in Figure 2 (6).

Figure 2 αυ is a brace, which is installed as necessary to obtain the necessary strength.

Figure 3 is a plan view of the ceiling of the girder seen from above, and O2 braces and 113 reinforcing materials are installed at appropriate locations to provide strength.

Figure 4 shows a girder attached to a ship, and to reinforce it, round reinforcements and α-bracings are installed at appropriate locations.
