Description

The invention relates to a securing device suitable for securing a heavy load, in particular a component of a wind turbine, on a transport frame or on a transport surface of a transport vehicle, in particular of a ship, with an abutment and a locking element, wherein the locking element is suitable for engaging in a receiving portion of the transport frame or of the transport surface and for producing a holding connection in conjunction with said receiving portion, and a transport frame system and a transport system consisting of a securing device and a transport frame system.

Due to the increasing use of renewable energies, a large number of ever-expanding wind turbines are being erected. This is taking place both onshore and offshore. Turbines with an output of more than 5 MW and hub heights of over 100 m are standard nowadays, especially in the offshore sector.

The decisive factors for the economical use of wind energy include the costs incurred in erecting the turbine and in the transport of the individual turbine components, as these account for a high proportion of the total costs. Producers of wind turbines obtain their components from their own production or from suppliers located around the world. Cost reduction is focused on this area. Cost-effective and safe transport must be guaranteed in this respect. Due to the large number of producers and suppliers, many of which began as small companies, individual transport systems have in part been developed specifically for each producer.

One component of the transport problem is the transport of the elements of the wind turbines on ships from a port where, for example, the producer of the elements has delivered its products to a port in the area in which the wind turbine is erected. This transport is substantially horizontal. For example, the elements are arranged on deck for transport. On particularly large special ships, however, vertical transport is also provided for. These may likewise be purely transport journeys from the producer.

Flowever, further significance is associated with vertical transport as the number of wind turbines erected offshore increases. The aim is for the components of the wind turbines to be transported vertically, as this has the advantage that the elements, for example in the case of tower segments, do not have to be transferred from the horizontal to the vertical at the erection site by a lifting device, such as a crane, which can lead to problems due to the weather conditions, in particular at sea. The vertically arranged tower segments can be removed directly from the hold of the ship or from the deck of the ship or a barge at the erection site and can be lifted and mounted directly without a change of position.

In the case of transport of containers, various systems for lashing the same onto transport surfaces or other containers are known, for example, from DE 10158737 al, DE 19709658 Al, FR 2323048 Al, WO 2005014439 Al or GB 2286424 A. However, such lashing means and transport systems cannot be used on or adapted for components in the area of heavy loads, in particular in the transport of components of wind turbines.

Up to now, the systems with which the components are transported have been tailored to the respective project. This has the disadvantage that with every new project, high development costs and possibly long procedures for approval by the certifiers are incurred in order to provide a suitable transport system. It is also necessary to provide each system component such as tower portions, nacelle, anchoring elements in the ground such as tripods or lattice masts with its own transport system, as these place different requirements concerning size, weight, etc. on the transport system.

The object of the invention is to provide a securing device, a transport frame system and a transport system suitable for transporting a heavy load, in particular a component of a wind turbine, on a transport surface of a transport vehicle, in particular a ship, with which it is possible, in the case of different heavy loads, in particular with different dimensions, to transport them safely with the same components and at the same time to enable rapid loading and unloading of the loads from the transport vehicle in the port or, for example, at the erection site of a wind turbine.

The object is solved with regard to the securing device in that a securing element is provided for producing a holding connection with the load, and in that the securing element is arranged between the abutment and the locking element such that an arresting force can be exerted on the securing element via the abutment and the locking element.

In this way, it is easily and universally possible to arrange the various components of the wind turbine on a transport frame or on a transport surface and to fasten and release the components quickly.

An advantageous teaching of the invention provides that the abutment is arranged in a manner acting against a portion of the securing element, and/or the locking element is arranged opposite the abutment in a manner acting against a further portion of the securing element, wherein the arresting force can be exerted in the direction of the securing element preferably by pressing together the abutment and the locking element, and therefore a vertical force acting on the load can be transmitted by the securing device into the transport frame or the transport surface. This makes it particularly easy to transmit vertical forces acting on the load into the transport frame or the transport surface. It is also possible to adapt to the load by providing abutments and/or locking elements of different dimensions. A further teaching of the invention provides that a bolt and an engagement portion are provided, the bolt is screwable into the engagement portion, the bolt has a force introduction portion, and the arresting force can be produced by screwing of the bolt into the engagement portion, wherein the force introduction portion is preferably connected to the abutment or to the locking element, and/or the engagement portion is part of the abutment or locking element or is arranged on a counter element. In this way, the necessary force can be provided particularly easily. Furthermore, depending on the load, the force introduction can be adapted by exchanging the bolts and/or counter elements. A further teaching of the invention provides that the securing element is rotatable or displaceable in relation to the abutment and/or the locking element in the non-arrested state. This makes it particularly easy to attach the securing device. A further teaching of the invention provides that the securing element has a plug- through opening for an insertion portion of the abutment or of the locking element and/or for the bolt, wherein the insertion portion and plug-through opening are preferably designed in such a corresponding manner that a horizontal force acting on the load can be transmitted by the securing device into the transport frame or the transport surface. A further teaching of the invention provides that the plug-through opening is designed in such a manner that the securing element is displaceable in relation to the abutment and the locking element in the non-arrested state, wherein, preferably, the plug-through opening has a holding portion, particularly preferably in the form of at least one projection, and the abutment or the locking element has a corresponding holding portion, particularly preferably in the form of at least one projection, wherein the holding portions are designed in such a manner that a form-fitting connection can be produced. As a result, for example, different diameters of the components can be compensated for during the securing and at the same time adequate absorption of the forces acting horizontally on the load can be ensured. A further teaching of the invention provides that the securing element has a connecting element for producing a connection to the load, and/or a fitting piece, wherein the fitting piece and/or the connecting element are preferably arranged movably in relation to the securing element. By providing different connecting pieces, the securing device can be easily adapted to different components, the connector having to be changed only depending on the component. Using a fitting piece, it is particularly easy to provide a secure horizontally acting connection by means of length compensation. A further teaching of the invention provides that the locking element has a guide portion and/or a holding portion on which a holding element, preferably in the form of at least one projection, is arranged. This allows an appropriate form-fitting connection to be provided. A further teaching of the invention provides that the connector has a force transmission portion which preferably has a horizontal and a vertical strut, which struts are connected to each other via a diagonal strut. This makes it easier to absorb and dissipate vertical force components in particular. A further teaching of the invention provides that a rotary connection element is provided on the force transmission portion, preferably on the horizontal strut, wherein the rotary connection element, preferably in the form of a latching portion, protrudes beyond the horizontal strut, and/or in that a connection portion is provided on the force transmission portion, preferably on the vertical strut. This makes it easy to position the connecting element correctly in relation to the load. Furthermore, it is advantageous that a guide element can be arranged on the rotary connection element, which guide element preferably has a rotary element receptacle on one side and a contact surface on the opposite side for making contact with the load. The guide element makes it possible to transmit compressive forces, so that the guide element ensures the correct arrangement of the connecting element and at the same time functions as a pressure transmission element. A further teaching of the invention provides that the locking element has a connecting portion which preferably has a plug-through opening and/or a projection as an abutment for an arresting element. Preferably, the plug-through opening is elongated, so that length compensation is possible.

Furthermore, the object according to the invention is solved with regard to the transport frame by a transport frame system, suitable for transporting a heavy load, in particular a component of a wind turbine, on a transport surface of a transport vehicle, in particular of a ship, with at least one transport frame portion, with a receiving portion, which is arranged on the transport frame portion, for receiving a securing device, in particular as described above, for securing the load on the transport frame portion, and with at least one fastening means receptacle for receiving a fastening means for securing the transport frame portion on a transport surface, characterised in that the receiving portion extends at least in sections along a side wall of the transport frame portion and has a holding element which is suitable for providing a holding connection to the securing device.

This makes it possible to provide a basis for a load that can be adapted to the load by particularly simple arrangement on the transport surface.

An advantageous teaching of the invention provides that the at least two transport frame portions are provided, preferably are arranged parallel to each other, said transport frame portions each having at least one receiving portion and being connectable via a connecting means, wherein a receptacle for the connecting means is provided preferably on one side of the transport frame portion, and/or the connecting means is a turnbuckle rod. This further improves adaptability to the load. A further teaching of the invention provides that the receiving portion is designed in the manner of a slot, is arranged in the upper side of the transport frame portion, extends over a substantial part of the transport frame portion, and/or the holding element is at least one projection via which a formfitting, holding connection to the securing device can be produced, and/or in that a contact portion is provided via which a vertically holding connection can be provided between the transport frame portion and the securing element. These design possibilities for the receiving portion make it particularly easy to arrange a securing device on the transport frame portion depending on the respective dimension of the load. A further teaching of the invention provides that the receiving portion has an insertion portion for the securing device, and/or in that the fastening means receptacle is arranged on the lower side with respect to the receiving portion. This greatly simplifies the attachment of securing devices between the transport frame portion and the load or between the transport frame portion and the transport surface. A further teaching of the invention provides that the transport frame portion is designed in the manner of a carrier. This makes the transport frame portion easy to produce and universally applicable.

Furthermore, the object according to the invention with regard to the transport system by a transport system suitable for transporting a heavy load, in particular a component of a wind turbine, on a transport surface of a transport vehicle, in particular a ship, with a transport frame system described above and a securing device described above for securing the load on the transport frame system, wherein the holding element of the transport frame portion and the holding element of the locking element of the securing device are designed in such a manner that a holding connection can be produced between the transport frame portion and the securing device, said holding connection being suitable for transmitting horizontal and/or vertical forces and torques acting on the load to the transport surface.

The transport system makes it possible to safely transport different heavy loads on a transport surface of a transport vehicle, in particular a ship, with the same components and at the same time to enable rapid loading and unloading of the loads from the transport vehicle.

In the following, the invention is explained in more detail with reference to an exemplary embodiment in conjunction with a drawing, wherein:

Fig. 1 shows the transport of a load 300, here a so-called tripod, which serves as a foundation for a wind turbine in an upright position on a barge 400 as a transport vehicle, the barge 400 having a transport surface 410 and a rail system 420, with which the load 300 is transported onto the barge 400. In Fig. 1 the load 300 is arranged on the transport frame system 100 and connected to the transport frame system 100 via securing devices 10. The transport frame system 100 is connected to the transport surface 410 via fastening means not shown.

Fig. 2 shows a first embodiment of a securing device 10 according to the invention. The securing device has a locking element 11 and an abutment 12. A securing element 14 is arranged between the abutment 12 and the locking element 11. The securing element 14 has a first portion 15 arranged above, which engages with the abutment 12 when the securing device 10 is assembled. Furthermore, the securing element 14 has a portion 16 which is arranged opposite the portion 15 and, when mounted, is in operative engagement with the locking element 11 and an upper side 101 of a transport frame portion 102 of a transport frame system 100. Flowever, it is also possible for there to be no engagement with the portion 16 here. The abutment has a contact portion 37. Furthermore, the abutment 12 has an opening 38 through which a bolt 13 can be inserted. The bolt 13 has a threaded portion 17 and a force introduction portion 19.

The securing element 14 has a plug-through opening 21, which is designed in such a way that it corresponds to an insertion portion 22, which in this embodiment is arranged on the abutment 12, but can also alternatively be arranged on the locking element 11. Furthermore, the locking element 11 also has a receiving portion 33, which likewise corresponds to a part of the insertion portion 22 of the abutment 12. Furthermore, an engagement portion 18 is present in which the bolt 13 engages with its threaded portion 17 and is screwed into it. The engagement portion 18 is either part of the locking element 11 or part of a counter element 20, it also being possible for the counter element 20 to be designed as a separate component or as part of the locking element 11.

The securing element 14 also has a connecting element 27, which can be used to produce a holding connection to a portion 310 of the load, here the base plate 310 of the Tripod 300. The connecting element 27 can be designed in a variable manner, depending on the load to be transported. In the exemplary embodiment shown, the connecting element 27 has a fitting piece 28. For this purpose, openings 34 are provided in a holding portion 39, which is arranged on the securing element 14, through which openings 34 threaded bolts 35 can be plugged. Receptacles 36 for the threaded bolts 35 are provided in the fitting piece 28, so that the fitting piece 28 can be moved in the direction of movement in relation to the holding portion 39, so that the fitting piece 28 can be moved against a wall portion 330 of the load 300. This also allows fine adjustment of the connection between the securing element 14 and the connecting element 27. The holding portion 39 is connected to the securing element 14 via webs 40 for reinforcing the connection between the holding portion 39 and the securing element 14. The connecting element 27 is designed specifically for the type of load to be transported.

The locking element 11 has a base body 41, on which guide portions 29 are arranged laterally. A holding portion 30 is arranged on the upper side of the base body 41. The holding portion 30 has holding elements 31, which are designed here in the form of projections 32 and recesses 44. Furthermore, the base body 41 and the holding portion 30 arranged on the base body have the receiving portion 33. The force introduction portion 19 is arranged on the lower side of the base body 41 in the form of a counter element 20, the counter element 20 either being fastened directly to the base body 41 or attachable thereto in conjunction with the bolt 13.

The holding portion 30 is recessed from the base body 41 or the side surface 42 of the guide portion 29. In the region of this recess, the locking element 11 has a contact portion 43 for vertical force transmission. Recesses 44 are located between the projections 32, so that the holding element 31 has a sawtooth-like shape. A similar structure is also provided in a second embodiment in Fig. 3 for a securing element 14, which is arranged to be displaceable in relation to the abutment 12 and the locking element 11. The plug-through opening 21 has a holding portion 23, which has projections 24 and recesses 45. In a corresponding manner, a holding portion 25 is arranged on the contact portion 37 of the abutment 12, which also has projections 26 and recesses 46.

The projections 24, 26 and recesses 45, 46 of the holding portions 23, 25 are designed such that the holding portion 25 of the abutment 12 can be inserted into the holding portion 23 of the securing element 14. As long as the holding portion 25 is not inserted into the holding portion 23, in this embodiment the securing element 14 can be displaced in the direction of movement B in relation to the abutment 12 and the locking element 11. If the holding portion 25 of the abutment 12 is inserted into the holding portion 13 of the securing element 14, movement in the direction of movement B is prevented.

If the securing element 14 is arranged above the locking element 11 and the abutment 12 with its insertion portion 22 is inserted into the insertion opening 21 of the securing element 14 and in the receiving portion 33 of the locking element 11, but the bolt 13 is not yet completely screwed into the engagement portion 18 of the counter element 20, it is possible to rotate the securing element 14 in the direction of rotation C shown with respect to the abutment 12 and the locking element 11 and to align said securing element 14 in relation to the load 300. This is prevented by the arresting force to be introduced via the bolt with its engagement portion 18 and the force introduction portion 19 of the counter element 20 in the arrested state. In addition, a securing element, not shown, can be provided to also prevent rotation in the direction of rotation C.

Fig. 4 shows the assembled state for the embodiment of the securing device 10 according to Fig. 3, in which the abutment 12 with its holding portion 25 is inserted into the plug-through opening 21 of the securing element 14 and the holding portion 23 thereof. At the same time, the locking element 11 is arranged below the securing element 14 in the portion 16, the bolt 13 is inserted into the opening 38 of the abutment 12 and screwed into the engagement portion 18 of the counter element 20 with the threaded portion 17 thereof.

Fig. 5 shows a spatial view of a transport frame portion 102 of a transport frame system 100. The transport frame portion 102 has an upper side 101 which serves as a support surface for the load 300. Furthermore, the transport frame portion 102 has a side wall 105 and a further side wall 113 which are designed parallel to each other. In a lower side 111 there are fastening receptacles 104 for inserting fastening means, not shown, for attaching the transport frame portion 102 to a transport surface 410 of a transport means 400. On the upper side 101, a receiving portion 103 is shown, which extends in the manner of a slot along the side wall 105. This receiving portion 103 has at its ends an insertion portion 110 for inserting the securing device 10. Holding elements 106 are arranged at the margins 117 of the receiving portion 103. In this embodiment, the holding elements 106 consist of projections 109 and recesses 112. Inside the transport frame portion 102 below the receiving portion 103, there is a guide 114 with a guide surface 115 and side surface 116. This guide makes the securing device 10 easy to move in the receiving portion 103 (see Figs. 9 and 13). The side wall 105 is the one long outer wall of the transport frame portion 102. If a second transport frame portion 102 is used, as shown in Fig. 10, the side wall 113 is the side facing the other transport frame portion 102. A receptacle 107 is then arranged on the side wall 113 in each case, between which a connecting means 108 can be fastened. The connecting means 108 is a turnbuckle rod which makes it possible to connect the transport frame portions 102 to each other in a holding manner. At the same time, the two transport frame portions 102 can also be aligned with respect to the load 300 using the turnbuckle rod, if this is necessary.

Figures 6 to 13 show the insertion of the locking element 11 into a receiving portion 103 of a transport frame portion 102 of a transport frame system 100, which is fastened to a transport surface 410 of a transport means 400 (see Figs. 6 to 9). Then in Fig. 10 and Fig. 11 the load 300 is set down on the upper side 101 of the transport frame portion 102 in such a way that an opening 320 is located in a base plate 310 in a corresponding manner above the receiving portion 33 of the locking element 11. Then the plug-through opening 21 of the securing element 14 is placed on the base plate 310 so as to correspond to the opening 320 in the base plate 310, so that a contact surface 47 of the fitting piece 28 of the connecting element 27 engages with a side wall 330 of the tripod 310. Then the abutment 12 is plugged through the plug-through opening 21, the opening 320 and the receiving portion 33, the holding portion 25 with the projections 26 and the recesses 46 of the abutment 12 coming into engagement with the holding portion 23 and its projections 24 and recesses 45. The bolt 13 is then plugged through the opening 38 of the abutment 12 so that the threaded portion 17 of the bolt 13 engages into the engagement portion 18 of the counter element 20. After the bolt 13 is screwed down via the force introduction portion 19 into the engagement portion 18, a holding connection is produced between the securing element 10 of the load 300 and the transport frame portion 102 of the transport frame system 100. By rotating the threaded bolts 35 of the connecting element 27, the fitting piece 28 is screwed against the side wall 320 of the load 300 until there is a holding connection with the contact surface 47 at all points provided, so that horizontal movement of the load 300 in relation to the transport frame system 100 is not possible. Vertical movement of the load 300 in relation to the transport frame system 100 is prevented by the screwed-down bolt 13 and the arresting force applied as a result to the base plate 310 between the abutment 12, securing element 14, upper side 101 of the transport frame portion 102 and locking element 11. The load 300 is released in reverse order.

To insert the locking element 11 into the receiving portion 103, the locking element 11 is inserted into the receiving portion 110. The insertion portion 110 merges into the guide 114, which is provided by the guide surfaces 115 and the side surfaces 116. The height of the guide portions 29 is dimensioned such that the upper side of the holding portion 30 is located below the upper side 101 when the guide portions 29 stand up on the guide surface 115 as shown in Fig. 7. The locking element 11 is inserted into the insertion portion 110 in the direction of movement D. The locking element 11 is then moved in the direction of movement E in the receiving portion 103 until the desired point in the receiving portion 103 is reached at which the load 300 is to be fastened later. Once the locking element 11 has reached the corresponding point, it is ensured that the projections 32 of the holding portion 30 are in alignment with the recesses 112 and of the holding element 106 of the holding portion 103 and, analogously, the projections 109 of the holding element 106 are coincident with the recesses 44 of the holding portion 30. Once this has taken place, the locking element 11 can be lifted in the direction of movement F during further assembly so that the contact portion 43 of the locking element 11 engages with a corresponding contact portion 118 of the upper side 101 of the transport frame portion 102. Depending on the design, the upper side of the holding portion 30 is aligned in this position with the upper side 101 of the transport frame portion or the holding portion 30 is located below the upper side 101 of the transport frame portion 102 if the intention is to ensure that the load 300 only rests on the upper side 101 of the transport frame portion 102.

Fig. 14 shows a further embodiment of a securing device 10 according to the invention. The securing device has a locking element 11 and an abutment 12. A securing element 14 is arranged between the abutment 12 and the locking element 11. The securing element 14 has a first portion 15 arranged above, which engages with the abutment 12 when the securing device 10 is assembled. Furthermore, the securing element 14 has a portion 16 which is arranged opposite the portion 15 and, when mounted, is in operative engagement with the locking element 11 and an upper side 101 of a transport frame portion 102 of a transport frame system 100. However, it is also possible for there to be no engagement with the portion 16 here. The abutment has a contact portion 37. Furthermore, the abutment 12 has an opening 38 through which a bolt 13 can be inserted. The bolt 13 has a threaded portion 17 and a force introduction portion 19.

The securing element 14 has a plug-through opening 21 which is designed so that bolt 13 can be plugged through it and correspondingly screwed to the locking element 11 as described above. Alternatively, the locking element 11 can consist of a solid block with a bore hole.

The securing element 14 further has a connecting element 27, with which it is possible to produce a holding connection to a portion 310 of the load, here the base plate 310 of the tripod 300 and of at least one connecting lash 340, which has an opening 341 through which a bolt 342 can be plugged. The connecting element 27 can again be designed in a variable manner, depending on the load to be transported. In the exemplary embodiment shown, the connecting element 27 has a force transmission portion 48 and a connecting portion 49. The force transmission portion 48 is composed of a plurality of struts 50, 51, 52 assembled to form a triangle. The triangle has a horizontal strut 50, on the side of which facing away from the connecting portion 49 a vertical strut 51 is arranged substantially at right angles thereto. The diagonal strut 52 connects the sides of the struts facing away from the connecting point of the horizontal strut 50 and the vertical strut 51. Two connection plates 53 are arranged at the upper end of the vertical strut 51. The connection plates 53 each have an opening 54 through which the bolt 342 can be passed. In this way, a holding connection is produced in such a way between the force transmission portion 48 of the securing element 14 and the transporting load 300, here a tripod, that the connecting strap 340 can be connected to the two connection plates 53 and the openings 54, 341 respectively located therein can be connected to the bolt 342. A rotary connection element 55 is arranged in the connecting region between the horizontal strut 50 and the vertical strut 51. As shown in Fig. 14, the rotary connection element 55 can have a latching portion 65 which projects beyond the horizontal strut 50. Said latching portion 65 serves to engage the connecting element 27 with an indentation or opening 343 in the base plate 310 of the load. The rotary connection element 55 serves to align the connecting element 27 in relation to the tripod or load 300. For this purpose, a guide adapter 56 is provided which on one side has a rotary element receptacle 62 corresponding to the rotary connection element 55 and on the opposite side a contact surface 61, the contour of which coincides with the load 300. At the same time, this guide adapter 56 also serves as a pressure transmission element. In order to achieve sufficient stabilisation of the guide adapter 56 with the base plate 310 and the side wall 330 and the load 300, webs 68 are provided.

On the side of the horizontal strut 50 facing away from the rotary connection element 55, the connecting portion 49 of the connecting element 27 is provided. This has a base area 69 which is directly in alignment with the horizontal strut 50. For stabilisation, webs 66 are provided on the sides of the base area 69, which webs 66 cover both the base element 69 and the horizontal strut 50 in a holding manner. A plug-through opening 58 is provided in the base area 69 which extends in the longitudinal direction. A projection 59 is arranged at the end of the base area 69 opposite the horizontal strut 50, which projection 59 is also connected to the webs 66. The projection 59 has a contact surface 60 on its outer side.

The securing element 14 also has a plug-through opening 21. Furthermore, webs 40 are arranged on the upper side which are connected to a holding portion 39. Openings 34 are provided in the holding portion 39, through which threaded bolts 35 are plugged. Receptacle 36 are provided on the outer side of the holding portion 39 which are designed here in the form of flanged nuts. The bolts 35 are screwed into these nuts. The bolts are screwed in until the threaded bolts abut against the contact surface 60 and thus arrest the securing element 14 and the connecting element 27 when the connecting element 27 is in contact with the guide adapter 56 and the latter is pressed against the side wall 330 of the load 300.

The abutment 12 is rectangular in this embodiment. In its longitudinal extension it is as wide as the distance G between the webs 66 of the connecting element 27, so that it is not possible to rotate the abutment 12.
