Description

[0001] The invention relates to a load lifting system with a load holding system for coupling and moving a load, in particular a movable watercraft.

[0002] For the purposes of this invention, "load" means all types of recoverable, movable goods that can be moved by a lifting system, including loads on a watercraft that are connected to the watercraft or a hull or form part of the watercraft as a vehicle module, such as variable superstructures or sections, as well as the entire watercraft.

[0003] For the purposes of this invention, "watercraft" means all types of movable vehicles used in, on, or under water. This includes boats, ships, parts of boats or ships, rafts, submarines, drones, ROVs, AUVs, measuring platforms, seaworthy containers, and the like.

[0004] Document US 5,735,561 A discloses a lifting device for a small watercraft which engages on both sides of a hull at the gunwale.

[0005] A device and method for launching and retrieving a dinghy is known from publication WO 97 / 28 042 A2.

[0006] Furthermore, so-called G-type fast rescue craft davits are known from the prior art, which are also suitable for launching and retrieving heavier watercraft such as rescue and work boats (see www.macgregor.cn / products / products / davits / g-type-fast-rescuecraft-davits / ). The use of so-called "portable ship lifting A-frames for ships" is particularly well-known from their use on research vessels, which, in addition to containers and boats, also have to launch and recover ROVs and the like.

[0007] German patent application DE 82 00 963 U1 discloses a crane crossbeam for manipulating pallet racks equipped with lifting devices. The crane crossbeam has an I-shaped plan view and features at least one crane hook attachment eye. Projecting bolts are arranged on the four end faces of the two flanges, which can be engaged with the lifting devices of the pallet rack.

[0008] German patent application DE 41 26 573 A1 discloses a device for transporting and storing heavy cylindrical objects, such as rolls, spools, coils, or the like, particularly those made of metal. Each object to be transported and stored is placed in a holder designed to receive the object using the same crane grab equipped with a rotatable receiving element, and is transported and stored together with the holder. The holders are designed to receive one object at a time, are stackable side by side and on top of each other, and are connected to suspension devices for hanging from a crane.

[0009] From the publication DE 19 29 523 A, a device for handling floating containers is known, comprising a lifting device containing winches, e.g., located on a ship, and a supporting frame which is supported by flanged ropes, each connected to the winch drum by one strand, and which can be coupled to a container to be lifted out of the water or lowered into the water on its top side, using a device for keeping the winch ropes taut in rough seas.

[0010] Furthermore, US Patent 5163726 A discloses a cargo loading system comprising a spreader bar and an overhead restraint, the overhead restraint including an automatic locking mechanism for locking and unlocking the spreader bar. This automatic locking mechanism is actuated by twistlocks on the spreader bar and serves to eliminate the need for dockside personnel and the associated hazardous working conditions that arise for such personnel from the conventional fastening of the spreader bar and the overhead restraint with fastening pins.

[0011] Document WO 2005 / 113 405 A1 discloses a single-point lifting coupling comprising a frame for attachment to a cargo module, the frame containing a female coupling part. A complementary male coupling part can be attached to a lifting device, e.g., a crane. The male and female coupling parts can be coupled to each other so that the frame, and thus the associated cargo module, can be lifted by the single-point lifting coupling when the male part is inserted into the female part. The male and female parts can be reversed if desired, and one of the parts can bear a locking device for engagement with a cooperating formation on the other part when the male part enters the female part.

[0012] From European patent EP 2 752 361 A1, a lifting system is known which comprises the following features: a lifting crane with a lifting rope, a vehicle and a connector pawl arrangement for connecting the lifting crane and the vehicle or a load / cargo on the vehicle, wherein the connector pawl arrangement is provided with a connector body and a connector pawl with a funnel-shaped catch cage, wherein one of the connector body and the connector pawl is attached to the lifting rope and the other of the connector body and the connector pawl is attached to the vehicle or the load on the vehicle, and wherein the wide side of the funnel-shaped catch cage is directed towards the connector body when approaching each other, while the opposite narrow side of the funnel-shaped catch cage has the connector pawl mounted therein for releasably holding the connector body.

[0013] German patent application DE 10 2017 103 599 A1 discloses a lifting device for a motor vehicle assembly with a load-handling unit having at least one support arm pivotable about a longitudinal axis of the load-handling unit, and a coupling unit arranged on the support arm for detachably connecting the support arm to the motor vehicle assembly. The coupling unit is mounted longitudinally displaceably on the support arm, and the load-handling unit is designed for connection to a crane unit, in particular having a crane hook receptacle. To provide a lifting device of the type mentioned above, which is particularly compact and, if necessary, offers the possibility of being combined with lifting units for the ground-level dismantling of motor vehicle assemblies, it is provided that the load-handling unit is detachably connected to a connecting body of a support unit, the connecting body being tiltably arranged on the support unit.

[0014] Furthermore, publication AU 2016 282 064 A1 discloses a retrieval system for bringing a ship out of the water and onto the deck of a salvage vessel, comprising: a lifting device mounted on the deck of the salvage vessel, the lifting device comprising a substantially vertically extending structure and a lifting hook mounted on the substantially vertically extending structure in such a way that it can be raised and lowered by means of a first winch; a connecting line with a free end configured to be detachably connected to a connecting link of the ship to be salvaged from the water, with an opposite end of the connecting line located on the salvage vessel;a capturing element attached in relation to the lifting hook to capture the ship's connecting link when the free end of the connecting plate is raised towards the lifting hook; and a control element attached in relation to the lifting hook of the lifting device and configured to receive at least part of the connecting plate to guide the connecting link to the capturing element so that it may be captured when the free end of the connecting plate is raised towards the lifting hook; wherein, upon capture of the connecting link by the capturing element, the winch is actuated to facilitate the lifting of the ship out of the water onto the deck of the salvage vessel.

[0015] The problems with the current state of the art are essentially that in currently known load lifting systems with load holding systems, only a hook or a flange is used to couple the load to the lifting system, and therefore a controlled position and movement of the load when moving it in space is not possible.

[0016] The present invention is based on the objective of ensuring in a simple way that a load to be recovered can be coupled to a load lifting system with a load holding system, and that its position and movement during recovery or deployment can be controlled, tared and regulated, thus avoiding damage during the moving process.

[0017] This problem is solved with the inventive load-lifting system according to the main claim and further advantageous embodiments according to the dependent claims.

[0018] The load-lifting system with a crane, a lifting unit with two lifting ropes and a connectable and detachable connecting unit, is characterized in that the connecting unit is designed from: - a load-holding system to be arranged or arranged or arrangable on a load in a force-fit and / or form-fit and / or material-fit manner, comprising a first and a second A-shaped or lambda-shaped holder, wherein an arm of the respective holders is designed in such a way that movement and positioning and / or adjustment of the holders is possible, the respective holders are spaced apart from each other and in particular are connected to each other via a crossbeam, and a first and a second receptacle are arranged on the holders or, if a crossbeam is present, on the crossbeam at equal intervals from the center of the distance between the respective holders, and at least one detachable and connectable connecting element on the respective holders or, if a crossbeam crossbeam is present, is arranged on the crossbeam crossbeam and - a crossbeam support element arranged on the two lifting ropes at their load-facing end in a force-fit and / or form-fit and / or material-fit and / or detachable manner, with a first coupling element corresponding to the first receiving point and a second coupling element corresponding to the second receiving point, wherein the respective coupling element can be inserted into the respective corresponding receiving point, wherein a stabilizing support in at least two spatial directions is enabled, and at least one load connection element corresponding to the at least one connecting element is arranged on the crossbeam support element, wherein a load-bearing connection is made via the connectable and detachable connection between the connecting element and the load connection element.

[0019] Furthermore, the first or second receptacle and the associated first or second coupling element can be designed as a pin or pin receptacle for a common pin-to-pin receptacle connection.

[0020] In a further development, the first and / or the second coupling element can be adjustable relative to each other in their distance and / or the traverse support element can be adjustable in its length.

[0021] Furthermore, the connectable / detachable connection between the connecting element and the load connecting element can be designed as at least one bolt connection, wherein the respective bolt can be inserted / removed by means of hydraulic and / or pneumatic and / or electrical and / or mechanical aids.

[0022] In a further training, the holders can be positioned longitudinally on the load.

[0023] The movement, positioning and / or adjustment of the holders can be carried out using means and / or a combination of means selected from the list: hydraulic means, rails, electrical means, screw connections, bolt connections, weld connections, adhesive connections, locking mechanisms, rotary means.

[0024] Furthermore, the respective holders must have at least one lever arm.

[0025] In particular, the load may be a watercraft to which the respective holders are attached.

[0026] In a preferred training variant, the crane can be designed as a davit system and / or the crane can be arranged on a watercraft, a platform or a slipway.

[0027] The inventive load lifting system with load holding system can in particular be attached to the load or a movable watercraft using the load holding system and thus moved via the load lifting system.

[0028] If the load is a watercraft, then the entire watercraft can be easily, safely and stably lifted and moved using the inventive load lifting system with load support system.

[0029] The invention is described below with reference to the accompanying figures in the figure description, which are intended to explain the invention and are not necessarily to be considered limiting:

[0030] They show: Fig. a side view of a load with an exemplary inventive load lifting system with load holding system with a lambda holder as a frame; Fig. the exemplary inventive load lifting system with load holding system with a lambda holder as a frame made of Fig. in detail in perspective view; Fig. an exemplary inventive load lifting system with load holding system with an A-holder as frame in detail in side view; Fig. a rear view of an exemplary inventive load lifting system with a load holding system, with each holder forming a frame pair in the open state; Fig. a front view of a load with an exemplary inventive load lifting system with load holding system with respective holders as a frame pair in locked state; Fig. a section of an exemplary inventive load lifting system with load holding system in locked state in side view; Fig. , Fig. , Fig. until Fig. The individual phases of a load relocation process using an exemplary inventive load lifting system are shown in four views.

[0031] In Fig. Figure 1 shows a side view of a load 6 with an exemplary inventive load lifting system 1, comprising a load holding system 41 with a so-called first lambda holder 411, which conceals the second lambda holder 412 in the side view, and a first receptacle / pin receptacle 414, which conceals the second receptacle / pin receptacle 415 in the side view. The load 6 is indicated by a cutaway drawing of a launching boat. On the hull of the launching boat, a first and a second lambda holder are detachably attached as frames, each via a load holding system 41, approximately centrally, near the center of gravity, on the port and starboard sides at the same height.One arm of the respective lambda holder 411, 412, acting as a frame, is designed such that the holders 411, 412 can be moved, positioned, and / or adjusted using means and / or a combination of means selected from the following list: hydraulic means, rails, electrical means, screw connections, bolts, welds, adhesives, locking mechanisms, and rotary means. By moving, positioning, and / or adjusting the holders, the load 6 can be dynamically balanced in its relative position by means of a control or automatic regulation system.

[0032] In Fig. is an exemplary inventive load lifting system with load holding system with a lambda holder 411,412 made of Fig. The frame is shown in detail in a perspective view. The movement paths of the uppermost point, lambda holder 411, 412, as a frame, and the guide attachment above the receptacle / pin receptacle 414, 415, which accommodate the corresponding coupling elements / pins 421, 422, are each provided with a line drawing that exemplifies the movement, positioning, and / or adjustment possibilities of these points of the inventive load lifting system with load holding system.

[0033] Fig. Figure 1 shows an exemplary inventive load lifting system with a load holding system, comprising an A-holder 411, 412 as a frame, in detail in a side view. An arm of the respective A-holder 411, 412 as a frame is designed such that the holders 411, 412 can be moved, positioned, and / or adjusted by means and / or a combination of means selected from the following list: hydraulic means, rails, electrical means, screws, bolts, welds, adhesives, locking mechanisms, and rotary means. In this example, the load holding system 41 is detachably mounted on a rail on the load 6. Whereby only one arm of the A-holder 411,412 is acted upon as a frame by means of displacement in the direction of the longitudinal axis of the rail, and by moving, positioning and / or adjusting the load 6 in a center of gravity position can be dynamically balanced in the relative position by a control or automatic regulation of the means.

[0034] In Fig. Figure 1 shows a rear view of an exemplary inventive load-lifting system with a load-holding system, each holder forming a frame pair in the open position as a connecting unit 4. In the upper part of the figure, a crossbeam support element 42 is shown, which is connected via the lifting cables 31, 32 to a lifting unit 3 (not shown). The lifting unit 3 can be a crane 2 positioned on a movable or stationary load carrier, such as a supply or research vessel, on a pier, pontoon, offshore platform, or the like. The crossbeam support element 42 has spaced-apart coupling elements / pins and load-connecting elements. In the example, a first and a second coupling element / pin 421, 422 and a load-connecting element 423 are shown. However, the crossbeam support element 42 is not limited to these.Furthermore, the traverse support element 42 is preferably variable in length and / or several coupling elements / pins spaced differently apart can be attached, so that the traverse support element 42 with the respective coupling elements / pins can be easily adapted to corresponding supports / pin supports.

[0035] The example shows such first and second mountings / pin receptacles 414, 415 on a load-holding system with a respective holder 411, 412 forming a frame. A crossbeam 413 provides spacing between the holders 411, 412. In the example, a detachable / connectable connecting element 416 is attached to the crossbeam 413, which corresponds positionally to the load-connecting element 423. Funnel-shaped guides are shown above the mountings / pin receptacles 414, 415, which simplify the coupling process of corresponding coupling elements / pins with the mountings / pin receptacles.

[0036] In Fig. Figure 1 shows a front view of an exemplary inventive load lifting system with a load holding system, each holding a frame pair in the closed state as a connecting unit 4. The connecting unit 4, coupled to the load connecting element 423 by a detachable / connectable connecting element 416, is in this state able to move the load 6 connected via the load holding system 41 in a counterbalanced manner.

[0037] The figure shows the traverse support element 42, which is connected via the lifting cables 31, 32 to a lifting unit 3 (not shown). The traverse support element 42 has a first and a second coupling element / pin 421, 422 and a load connection element 423, which are each engaged and coupled with the corresponding first and second receptacles / pin receptacles 414, 415 on a load support system with a respective holder 411, 412 and with the detachable / connectable connecting element 416 on the crossbeam 413.

[0038] Depending on the type of load 6, the crossbeam 413 may be omitted in individual cases. In this case, the coupling and detachable / connectable connection is made directly via the respective coupling elements / pins with the corresponding receptacles / pin receptacles. The respective holders are connected directly to the respective receptacles / pin receptacles. The necessary stiffness is then generated solely by the crossbeam support element 42 in conjunction with the load-holding system 41.

[0039] Fig. Figure 1 shows a section of an exemplary inventive load lifting system with a load holding system in the locked state, in a side view. The crossbeam support element 42 is connected to a lifting unit 3 (not shown) via the lifting cables 31. The first coupling element / pin 421 engages in the corresponding first receptacle / pin receptacle 414 on the load holding system with the holder 411 and is coupled via a bolt using the detachable and connectable connecting element 416. The funnel-shaped guide illustrates the relative geometric relationships.
