The present invention relates to a Verladearm device for loading fluids, in particular for loading fuel. Furthermore, the invention relates to a connection group for a Verladearmvorrichtung, in particular for a proposed Verladearm device, and a method for operating a Verladearm device.

The applicant distributes and manufactures loading arms for different applications. In this regard, reference is made to the Verladearme resulting from the website of the applicant www.svt-gmbh.com . A typical Schiffsverladearm with connecting device is for example from the DE 86 127 69 U1 out. In land loading devices, for example, horizontal boom are known, as shown in the DE 355 234 72 A1 emerge.

This object is achieved with a Verladearm device having the features of claim 1, with a terminal group having the features of claim 13, with a method having the features of claim 16 and with a use with the features of claim 17. Further advantageous embodiments but also features will become apparent from the respective dependent claims. The present independent claims are to be understood as a first draft of a formulation of the invention. One or more features of the independent claims may be further specified by one or more features of the following description as well as of the figures. On the other hand, there is the possibility that one or more features of the independent claims are either deleted or replaced by one or more other features of the description or the figures.

• eine Armkonstruktion mit zumindest einem ersten und einem zweiten jeweils beweglich angeordneten Teilarm, die eine erste kinematische Kette bilden, und mit einer zweiten kinematischen Kette aufweisend ein Gestängesystem, das zumindest ein Parallelgestänge zumindest zu einem der beiden Teilarme aufweist,

It is proposed a Verladearm device for loading fluids, which preferably comprises the following components:

• an arm construction having at least a first and a second respectively movably arranged partial arm, which form a first kinematic chain, and having a second kinematic chain comprising a linkage system which has at least one parallel linkage to at least one of the two partial arms,
• a pedestal, the pedestal having a rotatable head to which the first sub-arm is hingedly connected,
• an articulated coupling of the second kinematic chain to a connecting device, wherein the connecting device is pivotally coupled to the second arm of the first kinematic chain,
• a fluid line which is fluid-tightly coupled to the connection device, and
• an articulated coupling of the second kinematic chain on the pedestal, preferably on the rotatable head of the pedestal.

Such Verladearm device is in terms of their leadership able to impose a forced operation, especially in terms of the connection device can. This allows the connecting device, in particular depending on the type and arrangement of the respective articulated connections of the linkage system, preferably to be guided over an area in an approximately constant position. So there is the possibility that the arm construction is moved, for example. The movement takes place here on a fluid container, for example, to be filled, to which the connection device is to be coupled. By constructing the first as well as the second kinematic chain and the respective connection to the individual components of the Verladearm device it is possible, for example, to enable a horizontal alignment of the connection device via a pivoting region of the arm construction, which is present in particular in an area which also the includes immediate area of the coupling of the connection device to the fluid container with.

In particular, by the connection of the parallel linkage as proposed, it is possible to keep the terminal group in a preferably arbitrary predicament. Preferably, this predicament may be horizontal but also perpendicular with respect to the pedestal and its position, assuming that the terminal group has substantially a main extension for the coupling with the fluid container. The parallel linkage here is preferably able to allow the transmission of force to a desired reference point in the form of pull or push rods. This desired reference point is arranged according to an embodiment, for example in an upper region of the pedestal, in particular in the region of the rotatable head of the pedestal.

This forced guidance also makes it possible, in particular, for the terminal group itself not to need any internal counterbalance. Under an internal counterbalance is too understand that this, coupled to the Verladearm device without restraint assumes a horizontal orientation, but without tilting.

Another embodiment, in turn, provides that the used connection device itself also has a balanced weight distribution, that is, that there is internal weight compensation,

With regard to the rotatable head, that area is preferably used in the Verladearmvorrichtung, which is often referred to as a support frame. On this support frame, other components of the Verladearmvorrichtung can be arranged.

One refinement provides, for example, that the arm construction has a parallel guide transmission, which has at least two pivot points, wherein one or more elements of the parallel guide transmission run parallel to one or more elements of the arm construction. The parallel guide gear thus allows to finally transfer a linkage of the linkage system and the movement caused thereby caused by change in position of the sub-arms to the connecting device. By the parallel guidance of one or more elements of the parallel guide transmission to one or more elements of the arm construction, it is possible to preferably allow the connection device to follow in a forced operation.

A further embodiment provides, for example, that a positioning of swivel joints of the Verladearm device together with a parallel guide gear and the arm construction form at least one parallel guide. By means of at least one parallel guide, it can be ensured that the possibility of forcing the connecting device in case of an influencing articulation is created.

Furthermore, it is provided, for example, that the arm construction contains a resilient element for weight and / or length compensation. Preferably, the resilient element is arranged in the linkage system. For example, a pull or push rod of the linkage system has such a resilient element implemented so that, for example, occurring temperature changes this does not lead to undesirable inclinations of the linkage system. Furthermore, the resilient element can be used, for example, for an internal counterbalance, that is, for a balance of, for example, the arm construction or subregions thereof. For example There is the possibility that sub-areas are balanced among themselves, so that overall, the arm construction is thus balanced.

It is preferred that the linkage system of the second kinematic chain viewed from the top of the Verladearm device, at least approximately in a plane. As a result, the synchronization in particular but above all the space required for the arm construction and in particular for the linkage system is less in the broad than in height. This is the case in particular when, for example, the linkage system extends above and / or below the arm construction. A further embodiment provides that the linkage system of the second kinematic chain is arranged laterally of the arm construction. Even with such an arrangement, it is preferred that the linkage system extends at least approximately in a plane viewed from above the Verladearm device. The space requirement in the arm construction with laterally arranged solution for the linkage system, in turn, can be considered to be higher for the width, whereas for the height of the loading arm device, on the other hand, it can be smaller.

Furthermore, for example, there is the possibility that the linkage system extends on both sides to the pedestal and in the arm construction in each case on both sides to the two partial arms. Such a solution allows, for example, that pressure or tensile forces are divided. It is preferred here that these two laterally arranged partial linkage systems are the same. However, there is also the possibility that the linkage system of the second kinematic chain may be arranged with respect to the pedestal from above, such that it extends partly on one side of the arm construction and on the other side on an opposite side thereof.

A further embodiment provides that a third kinematic chain is provided for further positive guidance of the connection device. For example, this third kinematic chain has a further coupling to the connection device. For example, this coupling can be used so that the connection device itself can also have other different shapes. For example, the connection device may have three, but in particular also four joints. About these joints, the connecting device can take different positions and thus also be aligned differently.

Pivots, joints but also other couplings as and also described below can allow rotation in a plane. It can in particular Be swivel joints. In addition, however, there is also the possibility that these respective components may also have a variable axis of rotation and about a greater pivoting is possible. According to one embodiment, it is provided, for example, that the arm construction as well as the linkage system and the articulated coupling of the second kinematic chain to the connection device each have only hinges which have only a single axis of rotation. Another embodiment provides again that a Verladearm device has an arm construction with a linkage system, where there is at least one variable axis of rotation. The majority of the other pivot points, however, preferably has a fixed axis of rotation.

Furthermore, it is provided that the pedestal itself is preferably fixed, but at least detectable, for example in movable Verladearm devices. Due to the rotatable head, in particular a rotatable support frame, the arm structure can be pivoted with an axis of rotation extending along the pedestal. For this purpose, the axes of rotation of the first and second partial arm are preferably arranged perpendicularly. The articulated coupling to the connection device, in turn, can, for example, have an axis of rotation which preferably runs parallel to the axis of rotation through the pedestal column. However, this axis of rotation can also be arranged pivotably thereto.

The resilient element, which is present in the arm construction, can also be provided in the area of the connecting device. This depends in particular on the manner in which the coupling between the connection device on the one hand and the second kinematic chain is provided. The connecting device preferably has two couplings with the arm construction, wherein according to one embodiment, a coupling has an axis of rotation which is perpendicular to the axis of rotation of the rotatable head and the second coupling is also arranged perpendicular thereto and parallel to the first coupling axis. This allows in particular a positive guidance, in which the connecting device in a pivoting region has a constant positional alignment with respect to the plane over which the arm construction floats toward the fluid container.

A further advantageous embodiment provides, for example, that the arm construction by one or more counterweights, by an internal counterbalance and / or a Parallelführungsgetriebe with respect to its respective pivot joints a total weight balance has, preferably balanced, and a manual Actuating the Verladearm device is enabled. The total weight compensation enables a user of the Verladearm device in the position, without additional force generator, be it hydraulic or pneumatic power generator, rotation, pivoting as well as in particular to bring the connecting device to the docking fluid container only manually by using their own physical strength to be able to. The better the overall weight balancing has been done, the less force is here for users to apply.

For example, there is the possibility that by coupling a cable, a chain or the like, preferably at the connection device, the user only pulls on this. By Zubewegung on the fluid container follows the connecting device and thus the arm construction in further remaining Austarierung. As a result, a risk of injury is avoided, which could otherwise occur, for example, by the fact that the arm construction finally gets into an unstable position during pivoting, which can lead to a non-intentional movement of the arms and corresponding feedback via the cable or chain to the user.

In addition to a horizontal positional positioning of the connection device, however, this can also be forcibly guided in another way. For example, the connecting device with its coupling device, in particular a connecting flange facing up or down. Preferably, a forced operation is such that a risk to an operator is reduced, in particular taking into account the spatial relationships at the fluid container to be connected. For example, the connection device can be passed through a hatch, extend into an opening, extend into a depression or otherwise follow the connection conditions with its positional positioning. For example, the positional positioning may be adjustable. For example, can be changed by adjusting the linkage system, the positional positioning of the connection device. This can also be done for example via a change in the position of the coupling to the connection device. For example, this coupling is variably positionable on the connection device.

A further embodiment provides that the pedestal is a pipeline of the fluid line. This pipeline is preferably constructed so that it is able to absorb the weight that is transmitted to the articulated connection via the rotatable head and pass it on to the foundation. The pipeline has, for example, at its lower end a connection which leads to a further fluid container. For this, preferably a fluid is discharged. However, there is also the possibility that the Verladearm device is not used for filling, but for emptying. A refinement provides, for example, that the fluid line has, preferably consists of, pipelines connected to swivel joints. In this case, it can be provided, for example, that the upright pillar as well as the first and the second partial arm as well as optionally also a further, third arm are formed by a respective pipeline, which are connected by means of swivel joints. By using the swivel joints, it is possible to enable a fluid-tight fluid line. Furthermore, there is the possibility that by selecting the hinges and the use of the fluid line for cryogenic liquids. For example, it is provided according to a development that the Verladearm device is used for a bunkering of LNG in ships. Due to the temperature of the liquid LNGs such hinges are provided, which still have sufficient flexibility for the user when flowing through.

A further embodiment provides, for example, that at least the first kinematic chain of the arm construction is formed from pipe sections of the fluid line. For example, there is the possibility that runs along the pedestal a fluid line section, which is designed as a pipe or in any other way, for example as a hose line. This fluid line section can in turn be connected to the arm construction of pipelines, which then have the ability to absorb sufficient forces but also moments and forward. Yet another embodiment provides, for example, that the Verladearm device has a fluid line, which at least predominantly comprises a hose line. In particular, there is the possibility that along the Verladearm device exclusively a hose line runs, optionally connected at suitable points by suitable torsion joints. The latter is particularly advantageous when an otherwise too strong in-itself twisting of the fluid line is feared when pivoting the Verladearm device.

A further embodiment provides, for example, that the Verladearm device is arranged mobile. For this example, the pedestal is movable. You can be permanently installed on a traversing device. The traversing device may for example be a trailer, a bearing surface of a vehicle as well as, for example, a ship. Furthermore, there is the possibility that the Verladearm device is part of a crane design, the pillar itself is moved. For this purpose, this can be arranged for example on a motor-driven frame. A Another embodiment provides, for example, that the pedestal itself is the frame. In particular, however, due to the term pedestal, this feature is not to be understood as meaning that only a columnar structure must be provided. There is also the possibility that another vertically leading tower-like construction is used on which, in particular on the arm construction is arranged.

According to a further aspect of the invention, which is independently traceable, a connection group for a Verladearm device is preferably proposed according to one of the preceding claims for connection to a fluid container. The terminal group comprises at least three pivot points, the pivot points respectively connecting rigid elements of the firing group to each other, at least two pivot points having no axes of rotation parallel to each other and being provided with a pivot point for connection to the Verladearm device.

The use of at least three pivot points allows the connection group to be extremely flexible in terms of different movements. By arranging differently extending axes of rotation in particular pivoting in different directions can be ensured. This allows, for example, by means of the terminal group, the Verladearm device with its arm construction can stretch very far forward, the connection for the fluid container turn again may be more distant than usual from the pedestal column. In particular, this allows a design of the terminal group such that it has a very long-feeding arm, where the connection to the fluid container and the connecting piece is for this purpose. This is particularly advantageous for the bunkering of fuel in a ship, especially LNG fuel.

It is further preferred that the terminal group is connected to the Verladearm device via at least two pivot points, one of which is connected to a parallel guide gear of the Verladearm device. This allows in particular a forced guidance of the terminal group viewed from above in a plane. By way of this it is possible to be able to pivot the connection group in a specific position in a defined manner, without the positional arrangement of the connection group having to change with respect to its horizontal or vertical extent.

As already stated above, it is likewise preferred if the connection group has a resilient element for weight and / or length compensation. The springy Element may be, for example, a compensation element, in particular, for example, a pneumatic cylinder or a torsion spring.

According to a further aspect of the invention, which can likewise be continued independently, a method for operating a loading arm device is proposed, wherein a connecting device is forcibly guided at least in one plane by means of a parallel guide transmission.

The Verladearm device is preferably constructed as described above. The forced guidance of the parallel guide transmission allows the connecting device not to pivot with respect to its positional orientation, but remains constant with respect to their relative positional orientation to the ground. While components of the Verladearm device, in particular the arm structure pivot and thereby change their respective positional orientation, the connection device, for example, remain horizontal. Preferably, the forced operation is used when connecting the connection device to a filler neck of a ship. Usually, it is provided for this purpose that the filler neck is arranged on port and / or starboard in the direction of the rail. The connecting device is now guided to the filler neck, connected there, so that a fluid-tight connection exists. Then it starts with the fuel filling. The use of forcibly guided by means of parallel guide gear connection device allows a rolling motion of the ship, which is also possible in port but also in a bunker on speech, by the constant positional orientation of the connection device to master. In particular, this does not present the risk that, for example, the connecting device or a part thereof strikes a ship's wall or the deck, if, for example, when the connecting device is connected, the rolling movement leads to a lifting of the ship on this side. Also, abutment of the terminal device or a part thereof on a railing or other cross-bracing, under which the connecting device has been guided in-ship, is avoided. This can occur, for example, when during the rolling movement of the ship, this side of the ship should lower.

Another advantage is the possibility that the connecting device is not balanced by means of the positive guidance on the parallel guide transmission, but it can be used very long building. In particular, for a connection to bunkers, which are very far inside, thereby need not increase the geometry of the terminal group. In particular, it is not necessary to have to provide an ever greater counterweight, the longer this component of the terminal group towards Tank neck would extend. Rather, it is possible to transfer forces through the positive guidance on the Verladearm device and to derive them there on the pillar, for example in a foundation.

If LNG is preferably bunkered by means of the proposed loading arm device or the connection group in a ship and if in particular the loading arm device is predominantly, if not exclusively, provided for this purpose, it is provided, for example, that the linkage system and in particular the parallel printing or Drawbars approximately a distance of 20 cm to 30 cm from the fluid line, in particular the pipeline have. By such a distance, a temperature influence due to the flow of the cryogenic liquid can be at least reduced. Furthermore, however, it is advantageous if the linkage system has one or more resilient elements in order to be able to compensate for the shrinkage effects, in particular when using pipelines in the linkage system. This ensures that they do not warp and in particular no locking or too high wear due to distortion occurs.

The invention will be explained in more detail by several figures. Here, different details emerge from the different figures. The invention is not limited to any of the respective embodiments shown or to a figure. Rather, one or more features of one or more figures and embodiments may be linked to other features of other figures and embodiments as well as the above description to further developments.

a constructive implementation of the proposed Verladearm device using pipe sections as part arms and pedestal, which are connected by pipe joints.

FIG. 1 shows a schematic representation of a Verladearm device 1 according to the known prior art. Such Verladearm device 1 has a pedestal 2, a first arm 3 and a second arm 4. Each partial arm 3, 4 can each be provided with a counterweight 5, in order to enable weight compensation of the respective partial arms about their pivot points 6. At the second part of arm 4, a further pivot point 7 is arranged, on which a connecting device 8 is located. The connecting device 8 must be balanced due to the coupling via the pivot point 7. Otherwise, it would not have sufficient alignment of a coupling device 9 for a necessary connection. Such Verladearm devices may be very well balanced in terms of weight, but because of the need for the connection device must have the necessary internal balance, the problem that the coupling possibility is limited in such devices having a connection piece very far inside. For such connections, it would be necessary to construct very far-reaching connection devices, which in turn are very unwieldy and thus increase the risk of accidents during operation.

FIG. 2 shows a proposed Verladearm device 20 according to the invention. This has an arm construction 21, which has a first partial arm 22 and a second partial arm 23. The first partial arm 22 forms, together with the second partial arm 23, a first kinematic chain 24. Furthermore, the loading arm device 20 has a second kinematic chain 25. This is formed by a linkage system 26. The linkage system has according to this embodiment, a parallel guide gear 27. With this, the linkage system 26 may have a parallel linkage, for example as in this embodiment, as follows:

On the one hand, a first parallel linkage 28 is parallel to the first partial arm 22 and a second parallel linkage 29 extends parallel to the second partial arm 23 and coupled together via the parallel guide transmission 27. A connection device 30 is coupled to the linkage system 26 on the one hand, and on the other hand to the partial arms of the arm construction 21. In this way, there is a coupling with the first kinematic chain 24 as well as with the second kinematic chain 25. This allows the connecting device 30 can be positively guided. When the arm construction 21 is deflected, the first sub-arm 22 and the second sub-arm 23 move along a respective trajectory. Due to the coupling of the linkage system 26, which forms the second kinematic chain 25, this follows the deflection of the sub-arms. Due to the parallel guidance, in particular of the second kinematic chain 25, to the second partial arm 23, the connecting device 30 thus always follows a wide range in the fixed positional position due to two coupling points. As shown, the positional position of the connection device 30 is oriented horizontally, that is, the longitudinal extent of the connection device 30 is at least approximately parallel to a substrate on which a pedestal 31 and the Verladearm device 20 is arranged. A coupling part 32 can be held vertically in this way, no matter in which position the arm construction 21 is deflected. This succeeds therefore also with connection devices 30, which are not balanced. By coupling on one side of the first kinematic chain 24, on the other hand, the second kinematic chain 25, the weight forces are absorbed by these couplings, transmitted to the pillar via the respective chains and taken there due to their attachment or arrangement on a substrate or a mobile vehicle , This allows the connecting device 30, in addition to a positively guided position position over a Mindestauslenkbereich the arm construction 21 also opens up the option of being able to be built very long.

Furthermore, the twisting possibilities are shown by way of example around the individual pivot points. These are indicated in each case as arrows.

Preferably, the rotatable head 33 is rotatable about a longitudinal axis of the pedestal 31. In addition, as shown, a pivoting on the rotatable head 33 by the first arm 22 is possible. Also, the second kinematic chain 25 engages the rotatable head 33. In addition, there is the possibility that the entire pedestal 31 is rotatably arranged. As shown, the first as well as the second part of arm 22, 23 are pivoted in a starting position as a rest position when the pedestal 31 and the two arms 22 and 23 are approximately perpendicular. As a result, only a very small footprint is required in the rest position. If, for example, the connection device 30 is pivoted to bunker LNG fuel method, the two partial arms 22, 23 together with the linkage system 26 pivot on the one hand, wherein the coupling part 32 continues to remain perpendicular when approaching the bunker connection. Furthermore, the Verladearm device 20 can be rotated so far that a connection to a refillable tank is possible, which is not located directly opposite the pedestal 31. This is, for example, from the following FIG. 6 out. These will be discussed in more detail later. Thus, the positive guidance in particular also allow the connecting device 30 not only as indicated by dashed lines may have an approximately horizontal position. Rather, there is also the possibility that the connecting device 30 during a rotation of the pedestal 31 to a further also remains relatively constant position.

FIG. 3 shows a further embodiment of a Verladearm device 40 according to the invention. With this embodiment is shown that, for example, the arrangement of balancing weights 41, 42 is possible in various ways. For example, in the loading arm device 40 proposed here, the first counterweight 41 is connected to the second partial arm 45 via an articulated connection 46. The second balance weight 42, however, is arranged directly on the first part arm 44. As illustrated, the counterweights may be actual counterbalancing weights. However, there is also the possibility that the necessary for balancing masses are arranged distributed to the individual arms and / or but on the linkage. In this case, it is not a single one but multiple components that are responsible for balancing. In the illustrated embodiment, in turn, a pedestal 47 is provided. At this, for example, at a lower portion 48, a connection piece 49 may be arranged. About this can be liquid LNG be transported to the connection device 50, for example. Again, the linkage system 51 is provided, which in turn has two parallel guides in this case. These are connected to each other via the parallel guide gear 52, wherein the parallel guide gear 52 with the connecting device 50 is also directly connected. In this way, for example, the pedestal 47 holds the first arm 44, which in turn holds the second arm 45. At this turn, the connection device 50 is attached. In addition, the connection device 50 is also held by the linkage system 51, but in particular positively guided. For example, by a chain or a belt 53 can manually by an operator, the connection device 50 are attracted there, where finally the connection device is to be coupled. This is also possible with loading arm devices weighing, for example, 5 tons.

FIG. 4 shows the Verladearm device 40 from FIG. 3 , In this embodiment, it is shown that the connecting device 50 has various pivot joints, which allow the connecting device 50 is actually used in bunkering. Illustrated as a detail is a bunker hatch 54 of a ship. There is a connection piece 55 is provided, which is located far inboard. Only by an elongated connection device 50 is it possible to connect them there. The connecting device 50 has a first pivot point 56, a second pivot point 57, a third pivot point 58 and a fourth pivot point 59. The fourth pivot point 59 may be flanged in practice, for example, on the second arm 45. Another embodiment provides that the local flange connection on the partial arm 45 is released so that the fourth pivot point 59 remains on the connection device 50. Preferably, the second and the third hinge point 57, 58 on axes of rotation, which are preferably perpendicular to each other. These are indicated by dashed lines as an example. The first pivot point 56 preferably provides the possibility to enable rotation. This is indicated by the arrow. Also, a rotation is perceived by, for example, the fourth hinge point 59 corresponding to the indicated arrows.

FIG. 5 shows an exemplary embodiment of an embodiment of a proposed Verladearm device with attached proposed connection device 70. The connection device 70 is in turn designed slightly differently than the connection device, as it FIG. 4 evident. Connecting device as well as Verladearm device in FIG. 5 are viewed from above. It can be clearly seen that the forced guidance takes place in one plane. While the pillar 71, at the The first partial arm 72 runs, via which the second partial arm 73 can be pivoted, opening the possibility of providing a linkage system 74, which is arranged laterally of the two partial arms. The coupling with the respective components to be coupled, on the one hand the connecting device 70, on the other hand, the pedestal 71, is shown only very schematically. The connection device 70 has, for example, according to the illustrated form, the possibility of providing a pivoting of the coupling part 75. This allows further flexibility in connection. Illustrated are, by way of example, the various possibilities of rotation or pivoting possibilities through the individual articulation points of the exemplary connecting device 70 in the form of arrows.

FIG. 6 shows in exemplary embodiment, the Mitschwenken and turning on the one hand the Verladearm device, on the other hand, the connecting device 70. Starting from the basic positioning as in FIG. 5 The ship's position may change. Due to the various pivot points, it is possible to follow any movement. In particular, this allows that also preferably provided in the connection device 70 but also in the other proposed connection devices provided safety valve 76 does not trigger.

FIGS. 7 . 8th . 9 and 10 again show a further embodiment of a proposed Verladearm device 80 from each different views. Here, the proposed from the previous embodiments of a Verladearm device, only schematically illustrated components are implemented in a constructive solution. A first pipe part 81 is provided which has a connection 82 through which, for example, liquid LNG, ie a cryogenic liquid, can be guided. The first pipe part forms the pedestal. The first part arm 83 is in turn a pipeline which is connected via two swivel joints 84 with the sand column.
