Description

The present invention relates to a buoyant lifting pontoon for receiving a Transportguts, for example, a cargo, comprising at least one floating by at least one solid in water pontoon platform capable of receiving the cargo, and at least one support assembly with at least one support, the so movably arranged on the pontoon platform or can be arranged that it can be lowered to a lake bottom to raise and lower the pontoon platform together with the transported material relative to the lake bottom and absorb vertical loads, especially from the water to lift.

Lift pontoons are known in the art. They serve u. a. the simple, temporary installation of work platforms at sea, for example for cranes or in the repair and installation of oil rigs. About lifting by means of lowered to the bottom of the lake support assembly and the at least one support, it is possible to lift the pontoon platform out of the water and thus to ensure a fixed work platform even in rough seas. By lowering the supports to the bottom of the lake, the buoyant pontoon is fixed relative to this and held in position.

Such lifting pontoons, as known from the prior art, are very expensive to buy, but their scope is very limited. It is therefore an object of the present invention to provide a multi-functional lifting pontoon which allows a more versatile application.

This object is achieved by a buoyant lifting pontoon according to claim 1.

In particular, this object is achieved by a buoyant lifting pontoon for receiving a cargo, such as a ship or a cargo comprising at least one floating by at least one solid in water pontoon platform, which is suitable to receive the cargo, and at least one support assembly with at least a support which is movably arranged or arrangeable on the pontoon platform such that it can be lowered onto a lake bottom in order to raise and lower the pontoon platform together with the transported goods relative to the sea bottom while absorbing vertical loads, in particular lifting it out of the water, wherein the volume body is formed flooded so that the originally buoyant pontoon platform in the water is at least partially lowered.

An essential point is that by the at least one solid of the pontoon platform and its floatable design a lowering of the pontoon platform is also possible below the level of the water surface or the floating level of the platform, so that loading and unloading activities in and out out of the water. With such a lifting pontoon, for example, a ship can be transported out of the water to the dry, a dock, a transport ship, etc. Lowering the pontoon platform below the surface of the water makes it very easy to load and unload floating or in-water cargo.

Also can be done by means of such a lifting pontoons securing floating goods by the lifting pontoon brought by lowering the pontoon platform under the floating cargo and then raised so that a secure fixation between the lifting pontoon and the floating cargo, now supported by the lifting pontoon, is guaranteed. Such a position can optionally with lowered, placed on the bottom of the lake supports but optionally also with raised supports, so kept floating.

In addition, can be operated with such a lifting pontoon in an improved way water construction sites, dike security measures or similar construction sites, as cargo, such as breakwater, dike segments, etc. very easily taken over the hub pontoon of transport ships or the like storage funds and discharged to the bottom of the lake, etc. can be.

Due to the fact that the pontoon platform is designed to be liftable by means of the support arrangement, it is possible to dispense with additional, in particular cost-intensive, installations such as pump systems, etc.

Optionally, the pontoon platform comprises a plurality of solids, at least one of which is floatable. The possibly provided flooding volume bodies can be used, for example, as a safety reserve or as a stabilizing body, in particular in the floating position. It is also possible to provide a plurality of solids, which are in fluid communication or can be brought together. For example, the solids may be voids in the pontoon platform which are interconnected by plate members, beam members or the like to form a buoyant pontoon. Here are all known from the prior art method applicable.

Optionally, at least one volume body comprises at least one valve means, by means of which it can be brought into fluid communication with the outside environment, for example for flooding with water, and, for example, for securing against ingress of water, can be brought out of fluid communication. By means of the valve means, for example, the solids can be opened and the entry of water can be allowed, so that the solids fill up and the pontoon platform loses its buoyancy successively. It is possible to design the pontoon platform so that it completely loses buoyancy, but it is also possible to design it so that it loses buoyancy so that it can be lowered below the water surface to a certain height by means of actively operated supports is optional and there also stabilizable or durable. These supports will be discussed in detail below.

In addition, it is possible that the volume body comprises at least one valve means by means of which the fluid connection with the outside environment, for example for flooding with water during lowering and / or discharging water during lifting, can be maintained. This means that the valve means is designed so that the volume body can remain permanently open in order to allow the unimpeded or defined entry and exit of water. It is also possible to provide a valve means so as to control the amount of water and / or the flow rate upon entry and / or exit.

In principle, it is possible to design the valve means remotely, so that it can be opened and / or closed from a remote position. But it is also possible to form the valve means so that it can be opened or closed and in particular manually opened or closed on site, ie at the place where it is mounted.

For example, such a valve means may comprise an openable and closable bulkhead, with which an interior of the volume body can be brought into fluid communication with an external environment of the volume body or can be interrupted. Such a bulkhead can for example be screwed to a shell of the solid or fixed by a same openable closure element.

Particularly in this context, it is advantageous to lift the pontoon platform out of the water prior to opening the valve means so as to fluidly communicate the solids with the outside environment without endangering workers or fearing immediate lowering of the pontoon platform got to. After opening the valve means on the solids then the successive discharge of the pontoon platform in the water takes place, in which case the water penetrates into the open volume and the pontoon platform gradually sinks below the water surface. After lowering the pontoon platform under the water surface then a particular floating cargo, such as a ship, can be brought over a loading area of the pontoon platform, after which then the pontoon platform is raised again. This lifting is optionally carried out by means of the supports which lift the pontoon platform and, as soon as the goods to be transported come into contact with the pontoon platform, optionally also lift the cargo.

In particular, in this context, it should be mentioned that the lifting pontoon can also be equipped with appropriate hydraulic and pumping means to achieve the lifting of the lowered pontoon platform in the water by means of blowing out the water from the solids. The same applies optionally also for lowering in the water, in which case water can then be pumped into the solids by activating corresponding valves and / or pump means. Such an embodiment can also be done in combination with the aforementioned supports.

Optionally, the pontoon platform on a particular beveled bow and / or tail area, which facilitates the floating transport of the lifting pontoon.

For the movement of the at least one support of the at least one support arrangement, the support arrangement optionally has a lifting means, by means of which the support is movably arranged or arrangeable on the pontoon platform. "Can be arranged" in this context means in particular that it is also possible to provide a support so that it can be optionally arranged on the pontoon platform. It is thus possible, for example, to use supports of different lengths or dimensions on the pontoon platform or to use supports which can be lengthened or shortened if necessary.

It is also possible to design the pontoon platform in such a way that optionally a plurality of support arrangements can be arranged on the pontoon platform. In this way, for example, be adapted at very high expected loads of the lifting pontoon. The same applies to the subsoil over which the lifting pontoon is used. Depending on the nature, different support arrangements on the lifting pontoon can be used here.

Optionally, the lifting means comprises a hydraulic means for moving the support. Here are all known from the prior art hydraulic means for support movement of a support assembly applicable.

Optionally, the support is movably mounted vertically to the pontoon platform on the pontoon platform or can be arranged. In this way, the pontoon platform is very easy to raise or lower. It is also possible to arrange the support movable from the vertical deviating from the pontoon platform to the pontoon platform so as to achieve, for example, a fixation of the pontoon platform in a direction parallel to the water surface parallel direction. Column assemblies having a vertically moveable support and support assemblies having a non-vertically moveable support may be individually or in combination disposed on the pontoon platform. It is also possible to form support arrangements which optionally guarantee a vertical mobility of the support as well as a different mobility of the support.

Optionally, the pontoon platform on a loading area for the cargo and in particular arranged laterally thereof upwardly projecting leg. Upwardly projecting means protruding relative to the loading area of the pontoon platform, and particularly with respect to a horizontal plane which is parallel to the water surface. The loading area is optionally designed so that a lateral introduction of a transported material without the support arrangements being a hindrance is possible. Such an insertion area is optionally formed on at least one side of the pontoon platform and, in particular, optionally on opposite sides of a pontoon platform. This means that, for example, in the case of a quadrangular pontoon platform, the legs and support arrangements arranged thereon are optionally provided on two opposite sides, while no legs and / or support arrangements are provided on the other two opposite sides. Optionally, the pontoon platform in the region of the insertion area on a particular beveled bow and / or tail area.

Optionally, the legs are arranged on outer regions of the pontoon platform, so that there is loading area for the transported goods, which is not narrowed in its clearance profile by the legs and / or support assemblies. In particular, in such an embodiment, the legs project laterally from the pontoon platform.

Optionally, the pontoon platform in cross-section perpendicular to the horizontal plane, at least partially U-shaped or the like having lateral projections formed, optionally comprising a loading area for the cargo and in particular arranged laterally thighs. Seen in cross-section, therefore, optionally include the legs between the loading area between them. The legs may be arranged to extend closed along the side edges of the loading area, but it is also possible to form the legs only in sections.

Optionally, the legs are at least partially formed as a solid. In this way they contribute to the buoyancy of the platform, in particular for stabilizing the platform in the lowered state at.

Optionally, lifting means for moving at least one support and / or the like operating means for operating the lifting pontoon and in particular the support arrangements are arranged in particular at end regions of the legs. The end regions may be open to the environment, for example, but it is also possible to form the end regions closed to the environment.

Optionally, the lifting pontoon has a lowering limit for the pontoon platform such that in the maximum lowered state of the pontoon platform, the end portions of the legs are arranged above the water surface and / or protected by a barrier means protected from the water. In this way, the reliable arrangement of the resources, lifting means or the like control means for the pontoon platform is possible because they are always safely located above the water surface and do not fall even with a lowering of the pontoon platform below the water surface. It is also conceivable that optionally the lifting pontoon has a lowering limit for the pontoon platform such that in the maximum lowered state of the pontoon platform the operating means, lifting means or the like control means for the pontoon platform are arranged above the water surface and / or protected by a barrier means protected from the water. A Absenkbegrenzung, for example, be sensor-controlled, but it is also possible to form a Absenkbegrenzung purely manually, for example by appropriate off and on switch that start and stop the lowering of the platform as soon as a certain lowering depth is reached.

Optionally, at least parts of the lifting means, operating means or the like control means for the operation of the lifting pontoon are arranged at the end regions of the legs. However, it is also possible to arrange these means at least partially at arbitrary positions in watertight solids, so that a lowering of the pontoon platform takes place to a depth such that these solids are located below or in the area of the water surface.

Optionally, a plurality of supports is provided, which are arranged or arranged to be movable on the pontoon platform so that the pontoon platform can be lowered onto the bottom of the lake in order to raise and lower the pontoon platform relative to the seabed while absorbing vertical loads to lift the water.

In particular, in this context, optionally, a level control means is provided, via which the vertical position of the pontoon platform can be detected and / or regulated and in particular an inclination of the pontoon platform relative to the water level can be detected and / or regulated and / or the supports are each separately controllable the bottom of the lake can be lowered and the pontoon platform can be raised and / or lowered. In this way, therefore, a relative orientation of the pontoon platform can be achieved relative to the water level. It is also possible, if necessary, to tilt the pontoon platform so as to facilitate, for example, easier loading and unloading.

Optionally, the lifting pontoon and in particular the pontoon platform on coupling means, via which it can be detachably coupled with at least one further lifting pontoon or pontoon platform. In this way, several lift pontoons or pontoon platform can be coupled to larger units.

At the pontoon platform 2 are in both embodiments shown here a plurality and in particular four support assemblies 6 provided with at least one support 8th that are so movable on the pontoon platform 2 arranged or arrangeable are that the supports 8th on a lake bottom 104 are lowered to accommodate vertical loads the pontoon platform 2 relative to the lake bottom 104 raise or lower or relative to the water surface 108 lower and raise. In particular, it is possible via the column arrangements 6 the pontoon platform 2 out of the water 102 raise, as here in the 1 . 2 and 6 is shown. The 4 and 5 show the platform in a state where the platform 2 under the water surface 108 is lowered, here is a cargo 100 so buoyant is that it is off the platform 2 dissolves and floats.

To the pontoon platform 2 Floating to design, this has a plurality of solids in this embodiment 4 of which at least one is floatable formed around the originally buoyant pontoon platform 2 in the water 102 at least partially lower. That means that in the buoyant state the pontoon platform 2 over a flood of solids 4 relative to the water surface 108 can be lowered.

For this purpose optionally has at least one solid 4 at least one valve means 14 on, with whom he interacts with the outside environment 106 can be brought into fluid communication. Such a valve means may for example be an openable and closable bulkhead 15 be as shown here. By opening the valve means 14 may be the interior of the solid 4 with the outside environment 106 brought into fluid communication and so for example water 102 access is allowed. By such flooding of the solid 4 the pontoon platform 2 Can this be in the water 102 be lowered.

Optional is the valve means 14 Also designed such that the fluid communication between the outside environment and the interior of the volume body and thus closed the volume body can be closed again. Especially after lifting the pontoon platform 2 or the solid 4 From the water, water can leak out of the solid and then the closed volumes 4 back in the water 102 lowered to the pontoon platform 2 buoyant.

The valve means 14 or the bulkhead 15 are optionally also designed so that the fluid connection can be kept open to ensure the free entry and exit of water, for example when lowering the pontoon platform 2 or when lifting and in particular lifting out of the water.

To move the pontoon platform 2 In the water, the embodiment according to. 1 , optionally a bevelled bow and / or stern area 30 . 32 on.

In a particular embodiment, as well as in the 1 and 2 to 6 pictured is the pontoon platform 2 in cross section perpendicular to the horizontal plane xy (here a section along the zy plane), at least partially U-shaped or the like lateral projections 22 formed formed. These lateral projections 22 or thighs 22 close here a loading area 20 for receiving the transported goods 100 one.

In a particular embodiment, in particular at end regions 26 the thigh 22 lifting means 10 for moving at least one support 8th and / or similar resources 10 arranged to operate the lifting pontoon. Such resources 10 For example, they may be leveling agents, drive means or other technical equipment such as lighting means, communication means, etc. Optionally it is possible the thighs 22 and in particular their free end regions 26 via connecting means 11 to connect with each other, in particular the inclusion of other resources 10 serve and / or allow access to the thighs for workers (see 1 ).

An advantage of the arrangement of these means 10 in the end area 26 The thigh is that when lowering the pontoon platform these are in front of the water 102 are protected. This is especially true when the lifting pontoon 1 a lowering limit for the pontoon platform 2 such that in the maximum lowered state A _{M of} the pontoon platform 2 (please refer 4 and 5 ) the end areas 26 the thigh 22 above the water surface 108 are arranged. It is also possible, the resources through a barrier means in front of the water 102 protected form.

In the embodiments shown here are a plurality of support assemblies 6 or supports 8th provided, the movable at the pontoon platform 2 are arranged. The support arrangements are on opposite sides of the pontoon platform 2 arranged so that they have a freely accessible loading area 28 Include the unimpeded access to the loading area 20 allowed. Optionally, the pillar assemblies 6 arranged in at least two rows parallel to one another in the longitudinal direction X of the lifting pontoon.

In a particular embodiment, it is possible to provide the support assemblies with leveling means via which the vertical position of the pontoon platform 2 can be detected and / or regulated. It is also possible in particular, a slope of the pontoon platform relative to the water level 108 and / or the lake bottom 104 to detect and / or regulate and / or the supports 8th each separately adjustable to lower the seabed, so as to raise or lower the pontoon platform about the x and y axis pivotable in the direction of the z-axis.

Also it is possible at the pontoon platform 2 coupling agent 34 provide to the pontoon platform 2 to releasably couple with at least one other pontoon platform. Optional are also coupling agents 34 provided for securing cargo of the cargo (see 1 ).

As mentioned show the 2 to 6 a further embodiment of the lifting pontoon according to the invention, which is almost identical to that in 1 illustrated embodiment. Here is shown in particular how a schematically illustrated buoyant cargo 100 for example a ship 100 , by the lifting pontoon according to the invention 1 from a dock 110 in a water 102 can be lifted. The buoyant pontoon platform 2 This is done from a raised position in which the supports 6 get up on the lake floor under the water surface 108 lowered by the valve means 14 the solid 4 the pontoon platform 2 be opened. This is optionally done in the water 102 dug state, such as in 3 is shown (of course without cargo 100 that it should be loaded later).

In the 2 and 3 is an embodiment of the lifting pontoon 1 im out of the water 102 excavated state or in a raised but still in contact with the water state shown. In this state, loading the platform is, for example, from a dock 110 possible by the platform z. B. essentially the same surface to the dock 110 is raised. The cargo 100 can then, for example on slipcars, etc. on the platform 2 be ascended, etc. The 4 and 5 show the same platform 2 in lowered under the water surface state.

As in the 2 to 6 shown, can over the lifting pontoon invention 1 Loading or transport goods 100 from a dock 110 laden and especially at the level of the water surface 108 be lowered. Such a cargo in addition to buoyant cargo can not be buoyant cargo, for example. A building material for a construction site and especially a water construction site. In this respect, concrete components for dike construction work etc. can be delivered to the construction site with the buoyant lifting platform, where they can be deposited in the water in specific locations. This is optionally a slip car, as he z. B in 4 is shown provided for the transport of the load on and off the platform 2 allowed.

The loading area 20 It is optionally designed so that it is above the loading area 28 accessible and in particular with such a carriage carriage passable. Under the trolley 112 is here understood to mean any means that serves the movement of the cargo on, to or from the platform away and as it is known from the prior art and in particular from the charging technology. It is also possible on the pontoon platform corresponding (optionally actively driven) Slip wagons stationary form or provide appropriate loading means, such as floor rollers, etc.

Another embodiment of the lifting pontoons according to the invention 1 is in the 7 to 10 shown. The basic construction corresponds to the previously described embodiments. Here is shown in particular how a cargo 100 and in particular a ship 100 by the lifting pontoon according to the invention 1 out of the water 102 can be lifted. The buoyant pontoon platform 2 is under the water surface 108 lowered by the valve means 14 the solid 4 the pontoon platform 2 be opened. This is optionally done in the water 102 dug state, such as in 3 or 8th is shown (of course without cargo 100 that it should be loaded later).

By opening the valve means 14 and the ingress of water 102 into the solids 4 loses the buoyant pontoon platform 2 their buoyancy and sink at the supports 8th the column arrangements 6 under the water surface 108 , These are optional before the supports 8th the column arrangements 6 lowered to the bottom of the lake (see 1 , or too 4 and 5 ). Lowering the pontoon platform 2 takes place, for example, at least partially flooded solids 4 by weight. Once a certain loading depth, especially below the water surface 108 , the pontoon platform 2 is reached, the cargo can 100 , here the ship 100 , in the loading area 20 the lift pontoon 1 retracted or towed (see 7 ). Subsequently, via the column arrangements 8th the pontoon platform 2 raised again, in particular by opened valve means 14 For example, bulkhead ensures that water is out of the solids 4 exit. About the column arrangements 108 so can the cargo 100 lifted and in particular from the water 102 be dug (see 8th ). In this way, in particular the excavation of a floating cargo, in particular a ship, but also a no longer completely floatable cargo, such as a damaged ship, easily possible. Of course, it is also possible in this way to settle a particularly floatable cargo in the water.

As in 4 and 5 represented, is in this way beyond the lifting of a ship or similar cargo 100 out of the water and feeding to a dock 110 possible.
