Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lifting device for a submarine,

The present invention relates to a lifting device for a submarine.

Submarines are known to be extremely compact and space-saving. As a result, there is little or no droppage space in the submarine that can be used for cargo transportation. In particular, shipboard cargo is limited in size by, for example, the size of access to the interior of the submarine or by the size of the hatch inside the submarine. Thus, relatively large payloads, such as unmanned submersibles (UUV) or pressure-tight storage containers, can not be readily hoisted in a stream lining manner. Although it is known to place such payloads in, for example, the outer shell of a submarine, this has a significant impact on the driving profile and streamline characteristics of the submarine.

Furthermore, if it is possible to apply the payload at a relatively low cost for mission-specific requirements, the multi-use availability of the submarine can only be fully exploited. For loading of communication buoys, lifting devices utilizing the translational movement of a device rack from the prior art, for example EP 1 935 779 A2, are known in the prior art.

A challenge to be addressed by the present invention is to provide a device that is most space-saving that payloads can be exchanged at relatively high cost and can be applied to mission-specific requirements.

The present invention relates to a lifting device for a submarine for transporting a payload along a lifting direction,

The lifting device includes a first guiding element, a second guiding element, a first lifting element and a second lifting element,

The first lifting element is movably mounted on the first guiding element along the lifting direction,

The first lifting element and the first guiding element are joined together by a force applying means acting in the lifting direction,

The second lifting element and the second guiding element are joined together by another force applying means acting in the lifting direction,

The force application means and another force application means are synchronized, and the above problem is solved by the lifting device for the submarine.

Compared to the prior art, the lifting device according to the invention has the advantage that it is relatively space-saving and at the same time can lift very large loads. This is supported in particular by the fact that the first lifting element can be moved in the lifting direction and the force applying means acts in the lifting direction. This enables a linear deployment movement, which allows the lifting device to be placed in the submarine in the most space-saving manner possible.

Preferably, the payload at the loading position of the lifting device is located inside the submarine, preferably inside the upper deck of the submarine, while at the service position of the lifting device the payload is located outside the submarine, Is provided. The payload is connected directly or indirectly to the first lifting element and the lifting device is moved between the service position and the dropping position by displacement which takes place by the force application means of the first lifting element with respect to the first guide element . In addition, the force application means is provided such that its shape or shape during its movement between the service position and the dropping position, in particular its extension, which progresses in the lifting direction, is provided. For example, it is associated with a hydraulic lifting cylinder, whose cylinder piston extends from the service position and retracts from the loading position. It is also conceivable that the force application means comprises a spindle, a linkage system and / or an electric motor. Preferably, the lifting direction is substantially perpendicular to the extension of the outer skin of the outer cladding or submarine. In particular, the force application means and another force application means are synchronized in their movement during movement of the payload between the loading position and the service position. In this way, it can be ensured that the net weight of the payload during transport is evenly distributed over at least the first lifting element and at least the second lifting element.

Advantageous embodiments and modifications of the invention will be found in the subclaims and the detailed description with reference to the drawings.

According to another embodiment of the present invention, it is proposed that the force application means and / or another force application means is a lifting cylinder, in particular a hydraulic lifting cylinder.

According to another embodiment of the present invention, it is proposed that the lifting device comprises a regulating device and / or a distance measuring system for synchronization. By means of the adjusting device and / or the distance measuring system, an adjusting circuit can be formed which advantageously provides a controlled lifting of the rod. In particular, the lifting device comprises a magnetostrictive measuring system embedded as a distance measuring system, particularly preferably in a lifting cylinder and / or other lifting cylinder. For the evaluation of the data obtained by the distance measurement system and for the separate operation of the hydraulic cylinders and / or other hydraulic cylinders, the lifting device preferably comprises a regulating device. To this end, the measurement data obtained by each distance measurement system is transmitted to the conditioning device, which then operates the individual hydraulic lifting cylinders individually with the aid of the obtained measurement data. In this way, during the movement between the service position and the loading position, for example, a desired synchronization between the force application means and another force application means is advantageously ensured in order to avoid toppling over of the payload to be transported . Moreover, it is possible to enable different extension heights and different extension angles of the payload by the adjustment device.

According to another embodiment of the present invention, it is proposed that the first guiding element has two opposing guide rails and a first lifting element in the form of a lifting frame is arranged between the two opposing guide rails. It is also provided that a sliding element is arranged between the first lifting element and the first guiding element to advantageously reduce any frictional resistance between the first lifting element and the first guiding element. It is also possible that the sliding element is arranged on the sled body and / or on the sled body, which is then pivotally connected to the first lifting element about the bolt. In particular, it is provided that the sled body is designed to rest against the running surface of the first guide element, in particular against the running surface of one of the guide rails, thereby conveying the resulting guiding force. Under a load acting on the boom that is tightly connected to the sled body, the sled body can pivot about the axis of rotation indicated by the bolt within the limits of its guiding clearance. Due to the resultant support of the sliding elements relative to the guide rails, the first lifting element is guided in an advantageous manner. Also preferably, it is provided that the first guide element locks the first lifting element on both sides. In this way, the first guide element can advantageously ensure that the first lifting element can move along the lifting direction and prevent the first lifting element from tilting.

According to another embodiment of the invention, it is proposed that the first lifting element comprises a cantilevered boom for holding a support element, in particular a support element made of steel. It is proposed to place the payload on the support element. Preferably, the payload is reversibly secured to the support element by a fixation aid. In particular, the support element forms a boundary for the loading space provided by the lifting device. Preferably, the cantilevered boom is disposed at the lower end of the first holding element. In this way, the largest possible loading space can be realized in the lifting device. It is also proposed that the support element at the use position coincides with the outer skin of the submarine.

According to another embodiment of the invention, it is proposed that the support element is detachably connected to the boom. Preferably, the boom and the support element are detachably coupled together by a bolt connection. It may be considered to mount the payload on the support element. In this way, when a mission-specific environment is needed, the entire support element is preferably in a non-compliant manner with respect to another support element having another payload pre-mounted by the manufacturer and / As shown in FIG. When using such a modular support element, the entire support element on which the payload is mounted is released from the rest of the lifting device and is then displaced by the crane from the submarine and finally replaced by another support element with a different payload I can think about it.

According to another embodiment of the present invention, it is proposed that the first guide element is rigidly connected to the support frame and / or the support frame is connected to the structural part of the submarine by at least one shock absorber. Thanks to the shock absorber, the lifting device can be advantageously separated from the pressure vessel of the submarine. For example, the shock absorber is an elastomeric damper and / or a wire cable / spring damper. Using a shock absorber, it can advantageously be ensured that the lifting device and in particular the payload being carried, is not damaged during the impact on the submarine. The structural part is preferably a pressure vessel of a submarine. In order to equalize the curvature of the pressure vessel, a foundation welded to the pressure vessel and connected to the shock absorber is provided. It may also be considered that the force application means is connected to the support frame, for example by a Cardan joint or a ball and socket joint.

According to another embodiment of the present invention, it is proposed that the force applying means is disposed on the end face of the first lifting element facing away from the support frame. It may be envisaged that the force application means is connected to the first lifting element by, for example, a cardan joint or a ball and socket joint. This creates a flow of force which is particularly advantageous during the movement of the first lifting element by the force application means.

According to another embodiment of the present invention, it is proposed that the first guide element has a reinforcing portion. In this way, the first guide element is advantageously stabilized or strengthened against the force generated during operation of the lifting device.

According to a further embodiment of the invention it is proposed that the support element at the loading position is fixed to the support frame by a locking device, in particular by a passive locking device. Preferably, the locking device comprises a first locking element, such as a bushing, on the side of the support frame, and a second locking element, such as a locking pin, on the side of the supporting element. In particular, the first locking element and the second locking element are complementary in shape. It is also conceivable that the support frame and the support elements face each other at the dropping position and that the first and second connection elements couple together for locking of the lifting device. In this way, a compact and stable arrangement in the loading position is advantageously ensured, which ensures that the lifting device can be moved from the longitudinal and tangential forces which occur in the event of a collision, in particular damage, Protect.

According to another embodiment of the present invention, it is proposed that the lifting device comprises an outer cladding which moves with the first lifting element and the outer cladding is preferably connected to the first lifting element by an elastic connecting element. The resilient connection element preferably ensures that the shock to the outer cladding is buffered. Also, the outer cladding is provided to match the outer skin of the submarine, especially the outer skin of the upper deck. In this way, the streamline characteristics of the submarine are maintained substantially unaffected by the lifting device.
