description

The invention relates to a movable maritime transport device. The invention also relates to a movable transport device which is suitable move on water, land and / or swampy terrain.

Currently there are floating platforms as a movable maritime transport device on which lifting means, such as cranes. However, these devices have the disadvantage that they have a fuselage need large dimensions so that the hull offers sufficient stability to allow the loads to be lifted outside the perimeter of the hull surrounded by the water. In fact, by lifting the platform, it becomes of loads destabilized. When using it at sea, it is therefore necessary to check the condition of the Platform and in particular its depth must be taken into account. This limits the applicability of the platforms. In addition, due to their large dimensions, they are slow and difficult to maneuver.

There are also movable transport devices, in particular to dry out ships or to restore them to launch «These devices are generally used formed by a movable chassis, which can be moved on an inclined plane immersed in the water is. The ships are by means of the movable chassis

returned to dry land or water, attached to and moved with the chassis will.

Other movable devices include a frame which is mounted on wheels and which on a hard and flat surface is movable and in particular on two spaced parallel rails, which from the Lead out water. A ship to be brought to dryness is placed between the two rails, where the The scaffolding lifts the ship using lifting belts, for example, and then lifts it to dryness.

The lifting and transport of loads on the water thus requires boats of large dimensions which move only slowly. On the other hand, the transport of a load such as a ship from water to land and vice versa requires special facilities, which are generally expensive _{or the like}

One of the objects of the present invention is to provide a movable maritime transport device in which the lifting of the load, and more generally the loading, improves the stability of the device on the water.

Another object of the invention is to provide a movable maritime transport device in which the Resistance to locomotion on the water is less than that of currently known transport platforms.

Another object of the invention is to provide a transport device to create that is not only suitable for moving and transporting loads on water, but also also on the ground and on marshy terrain, and to transfer loads from one area to the other.

Another object of the invention is to provide a movable transport device that is better Has maneuverability than currently existing transport devices.

To solve the set tasks, a movable maritime transport device is designed according to the invention in such a way that that it has two elongated, slender hulls which are essentially parallel and symmetrical to a vertical one Arranged longitudinal center plane and equipped with drive means or control means and in the region of one of its ends are rigidly connected to each other and between them an open in the area of the fuselage ends that are not connected to each other Form aisle, and that the hulls are provided with complementary, lifting devices that are suitable between to carry a load on the two hulls.

If the device according to the invention is intended to move on water, land and / or marshy terrain, an advantageous embodiment of the invention consists in that the two hulls each comprise buoyancy means which are suitable for sucking in air and placing it between the hulls and eject their footprint. _O

The construction according to the invention has the advantage that the offer only a comparatively small resistance to the movement of the two slender hulls, and that through the Arrangement of the load between the two hulls in the loaded condition improves the stability. The design as a hovercraft, the possibilities for use improve even more.

Based on the following description of the in the drawing The illustrated embodiments of the invention will be explained in more detail.

It shows:

Fig. 1 shows an embodiment of the construction according to the invention in a perspective view and

FIG. 2 shows a view similar to FIG. 1 of another exemplary embodiment.

In the example shown in FIG. 1, the transport device has two hulls 1 and 2 which are arranged at a distance from one another and which are preferably substantially to one another run parallel. These hulls are arranged and essentially symmetrical to a vertical longitudinal plane have a slim shape with bow areas 3 and 4 and stern areas 5 and 6, respectively.

They preferably have drive means or control means known design, but the drive and control means of the two hulls can also be in the area of their controls be united.

The two hulls each have a bridge-shaped, substantially vertical framework 7 and 8, respectively. Each of these Scaffolding has two approximately vertical supports 9 and 10 on the framework 7 and 11 and 12 on the framework 8. These supports are their lower sections are connected to the deck of hulls 1 and 2, respectively.

One or more trusses connect the upper portions of the supports of each fuselage. For example two parallel traverses 13 and 14 are used for the scaffolding 7 shown, which are connected to the upper portions of the supports 9 and 10 and one below the other by two intermediate webs 15 and 16 are stiffened. The construction of the frame 8 is designed in the same way. Preferably they run the cross members connecting the upper portions of the supports are substantially horizontal and substantially parallel to the Longitudinal axis of the assigned trunk and parallel to each other »

This information is only to be understood as an example the person skilled in the art can easily determine a construction that is more suitable for both stands 7 and 8. In particular, could further supports can be provided in the central area of the two scaffolding.

The two hulls 1 and 2 are connected to one another in the area of one of their ends. In the example shown in FIG the two hulls are connected to one another in their bow area 3 and 4, respectively. You could also 5 or 6 be connected to each other.

The connection is preferably made by a traverse or several trusses are made, which connect the front supports 9 and 11 of each of the two hulls, or connect-, and possibly the front area of their respective traverses running parallel to the fuselage axis. In Fig. 1, for example, three cross members 17, 18 and 19 are shown. The two traverses 17 and 18 are used for fixed Connection of the two supports 9 and 11. The traverse 19 is at both ends with the front area of the traverse 13 of the frame 7 or the cross member 20 of the frame 8 firmly connected., The traverses 17 and 19 run essentially at right angles to the plane of symmetry of the device.

If necessary, the fixed connection between these cross members, which are arranged at right angles to one another, and the supports or the traverses parallel to the axis of the hulls by means of a triangular corner reinforcement, indicated schematically by 21 be reinforced.

In this way the two hulls 1 and 2 are one below the other firmly connected, the two frames 7 and 8 being arranged essentially vertically and symmetrically. The two hulls 1 1 and 2 form a lane 22 between them, which is open at one end, which in the case of FIG. 1 is the two rear areas 5 and 6 of the two hulls 1 and 2 are adjacent.

Each frame has complementary lifting means which allow loads to be lifted. These lifting means can be used by anyone of a suitable type and can easily be adapted by one skilled in the art to the loads borne by the device should. - 11 -

For example, four winches 23 to 26 are shown schematically in FIG. 1. The two winches 23 and 24 are located at the level of the upper cross member or the upper cross member of the frame 7 in that area which is in front of the rear section of the frame. It is the same with the winches 25 and 26, which are arranged in the area of the upper cross member or the upper cross member of the frame 8 are. The winches 23 and 25 as well as 24 and 26 are arranged in alignment with one another. They are intended to operate lifting belts, for example, which are shown schematically in dash-dotted lines Lines shown and denoted by 27 and 28 are »The two ends of the belt 27 are with the winches 23 and 25 connected. The two ends of the strap 28 are connected to winches 24 and 26.

Other means of absorbing the load could, for example, consist of a bridge or several bridges of known construction be formed, which are arranged rolling. These rolling bridges could, for example, have a winch carry, which is arranged to be movable transversely to the plane of symmetry of the transport device, or several such winds.

The transport device according to the invention is thus suitable for lifting and moving loads between the two "scaffolds, ie between the two hulls Improved stability on the water. _ _ΛΊ

Of course, the two hulls have a reserve of buoyancy or load-bearing capacity, which allows them to to keep oneself on the water even when the device is loaded with its maximum allowable load. The load could consist of a ship, a wreck, etc., for example. For example, in the case of a Ship this ship inserted into the lane 22 between the two hulls. If it is by means of the two straps 27, 28 and the winches 23 - 26 are to be lifted, the two straps are passed under the fuselage, with the Winches connected and then raised. It should be noted that in this case the two winches 23 and 25 as well as the Winches 24 and 26 are synchronized.

In the case of a wreck, the device according to the invention is arranged approximately vertically above the wreck, which then lifted to the surface by means of winches or a movable bridge and then between the two hulls is raised. It should be noted that the two hulls of the device according to the invention give good stability, which is also improved by the loading. On the other hand, the resistance of the device to locomotion becomes reduced in the water, as is known in boats of this type, i.e. in catamarans. Finally lend the drive and control means of the device present on each of the hulls are much better Maneuverability than is available on known platforms. Indeed, it is possible to carry out

- 13 -

Kerckove - 13 -

Maneuvers to use the drive and control means of each of the two hulls differently. In certain In some cases, the device, or more precisely, the two hulls 1 and 2 can be auxiliary drive means, for example in their front area to further improve maneuverability.

Preferably a bridge 29 runs between the different ones Supports 9 to 12 of the two scaffolding, parallel to the trusses carried by them. This bridge owns thus the shape of a U, the opening of which is in the area of the unconnected ends of the two hulls. These The bridge enables the crew to perform the various movements and the required movements Maneuver. If necessary, it has anchoring means such as bollards for lashing down the lifting devices raised load. These anchoring means are not shown in the drawing.

The operating elements for the drive means, the control means and the lifting devices are arranged, for example, in a wheelhouse 30, which advantageously has the bridge 29 can be arranged above one of the hulls. The wheelhouse can of course also be attached to any other Place of the transport device are arranged.

In another embodiment of the invention according to FIG. 2, the frames 7 and 8 are firmly connected to hulls 31 and 32, these hulls 31 and 32, however, buoyancy means for the suction of air and the expulsion of the

- 14 -

Kerckove - 14 -

Have air between the hulls and their contact areas. The two hulls 31 and 32 form a kind of air-cushion catamaran. You are at one of theirs Ends connected essentially in the same way as was described with reference to FIG.

Two skirts 33 and 34 are attached to the lower area of the two hulls 31 and 32, respectively. These aprons are well known Design and can optionally be divided into a plurality of individual sections, as is also the case is already known. When inflated, they limit the areas in which the compressed air is stronger Current is expelled.

Each hull preferably has suitable means for generating this buoyancy effect. These means are schematic shown at 35 and 36 on the two hulls 31 and 32, respectively.

Air propulsion means are used to enable the device to be propelled provided and shown schematically at 37 and 38. These means are of known type and exist for example from a plurality of propellers, which can be set in rotation. For example, they are preferably symmetrically attached to each of the hulls at the level of the cross members 30 and 20 of the two frames 7 and 8.

These propulsion means can be designed to be fixed or adjustable in an essentially horizontal plane. aside from that their number is not limited.

On the other hand, and advantageously, these propulsion means can be reversed, for example by using Variable pitch propellers. The control organs for these propulsion means are arranged in the wheelhouse 30.

As in the previous case, the lifting devices are of known design and are for example by winches or movable bridges formed.

Due to the buoyancy means, the transport device is movable suitable for moving equally well on water as on land and also on marshy terrain. It is also suitable for transferring loads from water to land and vice versa, or from land to swampy terrain, etc. move. For example, the transport device according to the invention is suitable to dry boats or ships To transport land and to transport them back into the water, etc. In addition, the device is due to the Buoyancy equipment is particularly maneuverable and can turn around itself, as is known from hovercraft is.

Of course, the hulls 31 and 32 represent in the event that the device moves on the water, reserves of buoyancy, which are at least sufficient with to keep the device buoyant when loaded to the maximum load.

On the other hand, the lifting devices are suitable in the event that the device is intended for the transport of ships, to raise the ships to an extent that at least

Equal to the draft of the ships.

The above description is only to be understood as an example and other embodiments of the invention are possible without departing from the scope of the invention. In particular, the two can be detachable lanyards
Connect hulls on the side where they are not rigidly connected to each other. In addition, the device can be provided with devices other than those mentioned for detecting the load.
