Description

[0001] Separating device for separating a cable guide unit from a connection and system consisting of a separating device and a cable guide unit

[0002] The invention relates to a separating device for separating a cable guide unit for guiding at least one power line, such as an electrical cable, hose or the like, from a connection, comprising an overload unit with a first part connected to the connection and a second part connected to the first part, wherein the two parts can be separated from one another automatically or in an externally controlled manner in the longitudinal direction when a tensile stress acting between the two parts in a longitudinal direction of the overload unit is greater than a predetermined tensile stress and is generated by a tensile stress acting between the connection and the cable guide unit, and the second part can be connected to the cable guide unit. The at least one power line guided in the cable guide unit can be detachably connected to the first part of the overload unit by means of a connector part.

[0003] The invention is based on the object of providing a separating device which protects the energy line and its connection to the first part via the connector part during the separating process.

[0004] The object is achieved by the combination of features of claim 1, namely by a separating device for separating a line guide unit for guiding at least one energy line, such as a cable, a hose or the like, from a connection, comprising

[0005] - an overload unit with a first part which can be firmly connected to the connection and a second part which can be firmly connected to the cable guide unit and which is detachably connected to the first part, wherein the second part can be released automatically or externally controlled in the longitudinal direction from the first part and can be freely moved in the longitudinal direction relative to the first part when a tensile stress acting between the two parts in a longitudinal direction L is greater than a first predetermined tensile stress and is generated by a tensile stress acting between the cable guide unit and the connection,

[0006] - a first component which is firmly connected to the first part and has a first connector part pointing in the longitudinal direction, which can be connected to a second connector part connected to the at least one power line guided through the line guide unit, and has a further connector part which is connected to the first connector part in a way that conducts energy and can be connected to a power line leading in the direction of the connection,

[0007] - a second component which is connectable to the second connector part connected to the power line guided through the line guide unit and is connected to the first component by a separating unit in such a way that when a second predetermined tensile stress between the two components is exceeded in the longitudinal direction, the second component can be detached from the first component and the second connector part with the power line connected thereto can be detached from the first connector part and the second part can be moved freely relative to the first part in the longitudinal direction, and

[0008] - a device by means of which the force acting on the second part in the longitudinal direction after the first part has been released from the second part of the overload unit can be transmitted to the second component.

[0009] By means of the separating device according to the invention, during normal operation, i.e. when the tensile stress between the two parts of the overload unit does not exceed the first predetermined tensile stress, and when the two parts are released from one another, no tensile force is transmitted to the at least one power line guided in the line guide unit and no force is transmitted which releases the connection between the first and the second connector part. Only after the two parts of the overload unit have been separated does the force acting on the second part in the longitudinal direction, when the second predetermined tensile stress between the two components is exceeded, cause the connection between the first connector part and the second connector part connected to the power line to be released in the longitudinal direction, although no tensile force is exerted on the power line.

[0010] The connection can be fixed, i.e., one that does not move in the longitudinal direction of the overload unit. It can be provided that the connection can move counter to the longitudinal direction. In this case, the connection exerts a tensile force on the cable guide unit. If the connection does not move counter to the longitudinal direction, the cable guide unit exerts a tensile force on the connection.

[0011] The predetermined second tensile stress can be less than or equal to the predetermined first tensile stress. The device, with which the force acting in the longitudinal direction from the second part of the overload unit to the second part after the first part has been released, can be transmitted to the second component, can have a first stop arranged on the second part of the overload unit and a first stop surface opposite the stop in the longitudinal direction, which is arranged at a predetermined distance from the stop on the second component.The second part of the overload unit, which moves freely in the longitudinal direction relative to the first part after the connection with the first part has been released, can hit the first stop surface of the second component with the first stop after overcoming the distance and can transfer the force acting on the second part in the longitudinal direction to the second component, wherein the tensile stress then caused between the two components and exceeding the predetermined second tensile stress causes the release of the separating connection between the two components and the further free movement of the second part of the overload unit with the second component in the longitudinal direction relative to the first part.

[0012] The first part of the overload unit can have a guide device on which the second part can be guided in the longitudinal direction relative to the first part.

[0013] The first component can be arranged at an end region of the guide device pointing in the longitudinal direction.

[0014] The first and / or second component can be plate-shaped and extend transversely to the longitudinal direction. Deviating from a flat plate shape, the plate-shaped design of the first and / or second component can be structured for the purpose of weight and material savings, statics, or attachment to the guide device.

[0015] The first component can have a second stop surface facing in the longitudinal direction, opposite which a second stop is arranged, which is attached to the second part of the overload unit at a predetermined distance from the stop surface in the longitudinal direction. The second stop, which cooperates with the second stop surface, causes a movement of the second part in the longitudinal direction, limited by the distance, when the two parts are connected.

[0016] The connection between the two parts of the overload unit, which can be released when the first predetermined tensile stress is exceeded, and / or the separating unit between the first and second components can be designed as mechanical connections. Alternatively, they can also be designed as magnetic or electromagnetic connections.

[0017] In particular, the mechanical connections can have a tear-off unit, such as a tear-off bolt, a tear-off rod, a tear-off cable or the like, which has a first region, a second region and an intermediate region connecting the two regions to one another, wherein the first region and / or the second region or the two regions in the intermediate region can be torn or broken off from one another if the tensile stress between the two parts of the overload unit or between the two components exceeds the respective predetermined tensile stress. In a tear-off unit of the overload unit, the first part of the overload unit can comprise the first region and the second part can comprise the second region of the tear-off unit. In a tear-off unit of the separation unit between the two components, the two regions of the tear-off unit can be fastened to the components.

[0018] The intermediate region of the tear-off unit may have a material taper relative to the two regions or a predetermined breaking point. Alternatively, the mechanical connection may comprise a region of tear-off or break-off-promoting material, interlocking tear-off or break-promoting, or bendable parts.

[0019] In general, any mechanical connections known to the person skilled in the art from his general knowledge or conceivable can be considered, which can be released when the first or second predetermined tensile stress between the two parts of the overload unit or the two components is exceeded.

[0020] The second part of the overload unit may comprise a longitudinally extending pull rod, which is detachably connected to the first part of the overload unit, as described above for the connection between the two parts of the overload unit, and is rigidly connectable to the cable guide unit at an end pointing in the longitudinal direction. The second component may be rigidly connected to the pull rod.

[0021] The first part of the overload unit can have a tube as a guide device for the pull rod, with which the pull rod can be guided in the longitudinal direction.

[0022] The first component can be arranged at an end region of the pull rod pointing in the longitudinal direction.

[0023] The first and / or second component can be designed and arranged to extend around the pull rod. The first stop, which may be provided on the second part of the overload unit, can be attached to the pull rod at a distance from a front side of the pull rod facing away from the longitudinal direction. The stop can be designed in the form of a flange extending around the pull rod.

[0024] Furthermore, the second stop, which may be provided on the second component, can be fastened to the pull rod at a distance from the end face of the pull rod pointing against the longitudinal direction, wherein the distance can be smaller than the distance between the end face and the first stop. The stop can be designed in the form of a flange extending around the pull rod. The second stop, which interacts with the second stop surface provided on the first component, brings about an insertion of the pull rod into the pipe with a length precisely dimensioned according to the distance, in order to arrange the mechanical connection between the pull rod and a part of the first part of the overload unit which can be connected to the fixed connection.

[0025] Furthermore, a fastening unit for fastening an end region of the power line, at which the power line is connected to the second connector part, can be provided on the pull rod.

[0026] The fastening unit for fastening the end region of the power line and the second component with the first connector part connectable to the second connector part can be fastened to a bushing extending around the pull rod and fastened to the latter.

[0027] A shackle can be arranged at an end region of the first part of the overload unit facing against the longitudinal direction, via which shackle the overload unit can be pivotably connected to the connection in the transverse direction to the longitudinal direction.

[0028] The disconnecting device according to the invention is designed in particular for a suspended cable guide unit with a strand suspended in a vertical direction or in a direction with a vertical component, which strand can be firmly connected to the second part of the overload unit. Suspended applications, in particular with comparatively long, freely suspended strands, e.g., in drilling rigs (offshore / onshore) or in civil engineering, e.g., on a drilling rig, or for supplying shore power to ships, exert high tensile forces on the suspended strand of the cable guide unit, which is attached to a connector, due to their heavy weight. This places correspondingly high demands on a disconnecting device connected to the cable guide unit and the connector parts. Therefore, in such suspended applications, it is particularly important that the high tensile forces do not act on the power lines connected to the disconnecting device and the connector parts connected to them.

[0029] The invention further relates to a system comprising a separating device for separating a cable guide unit for guiding at least one energy line, such as an electrical cable, a hose or the like, from a connection, and from such a cable guide unit with at least one energy line guided in the cable guide unit.

[0030] According to the invention, the separating device included in the system is designed according to the above-described separating device according to the invention with its above-described possible embodiments, wherein the second part of the overload unit is connected to the line guide unit, the first connector part arranged on the first component is connected to the second connector part connected to the power line and / or the further

[0031] Connector part is connected to the power line leading to the connection.

[0032] The cable guide unit connected to the second part of the overload unit can have a flexible support strand with high tensile strength and a number of guide bodies arranged one behind the other in the longitudinal direction of the support strand, wherein adjacent guide bodies can be spatially deflected relative to one another. At least some guide bodies, in particular all guide bodies, each comprise a central part with a fastening device for fastening to the support strand and an outer part with at least one circumferential element which delimits a receiving area for the at least one power line. Such cable guide units are described, for example, in WO 2019 / 243377 A1 and WO 2022 / 029148 A2 for so-called full-web and half-web embodiments.

[0033] The supporting strand of such a cable guide unit can be or is firmly connected to an end region of the second part of the overload unit pointing in the longitudinal direction.

[0034] One or more electrical cables having second connector parts configured as plugs can be routed in the cable routing unit. In this case, the first connector parts arranged on the first component, which can be connected or are connected to the plugs, are configured as sockets. In an alternative embodiment, the electrical cables can also be connected to second connector parts configured as sockets, which can be connected or are connected to first connector parts configured as plugs and arranged on the first component.

[0046] Figure 5A is a side view of the embodiment with complete separation of the first part and second part of the overload unit,

[0047] Figure 5B shows a longitudinal section through the embodiment shown in Figure 5A.

[0048] The separating device 1 of the embodiment shown in Figures 1A-1C comprises an overload unit with a first part 3 which can be firmly connected to a fixed connection 2 and a second part 5 which can be firmly connected to a cable guide unit 4 and which is connected to the first part 3 by a tear-off bolt 6.

[0049] The isolating device 1 further comprises a first component 7 which is fixedly connected to the first part 3 and has a plurality of first connector parts 9 pointing in a longitudinal direction L of the overload unit, which first connector parts 9 can be connected to second connector parts 10, wherein the second connector parts 10 are connected to cables 8 guided through the line guide unit 4. Arranged on the first component 7 are further connector parts 11 pointing counter to the longitudinal direction L, which are electrically conductively connected to the first connector parts 9 and can be connected to electrical cables 8 leading in the direction of the fixed connection 2.

[0050] Furthermore, the separating device 1 comprises a second component 12 which can be connected to the second connector parts 10 of the electrical cables 8 guided through the cable guide unit 4 and is detachably connected to the first component 7 by a separating unit 13 shown in Figure 3C.

[0051] The separating device 1 further comprises a device shown in more detail in Figure 3B, with which the tensile force acting on the second part 5 from the cable guide unit 4 can be transferred to the second component 7 when the detachable connection between the first part 3 and the second part 5 of the overload unit is separated.

[0052] The first connector parts 9 and further connector parts 11 arranged on the first component 7 are designed as sockets, while the second connector parts 10 connected to the electrical cables 8, as well as the connector parts connected to the electrical cables 8 leading to the fixed connection 2, which can be connected to the further connector parts 11, are designed as plugs 13.

[0053] In the exemplary embodiment shown in Figures 1A and 1B, which is in the normal operating state, the cable guide unit 4 is connected to the second part 5 of the overload unit and the plugs 13 are connected to the first connector parts 9 designed as sockets and to further connector parts 11. The tensile force acting on the second part 5, which is generated by the weight of the cable guide unit 4, causes a tensile stress between the first part 3 and the second part 5 of the overload unit, which is smaller than a first predetermined tensile stress at which the tear-off bolt 6 would break. However, the tensile force does not act on the cables 8 guided through the cable guide unit 4 and the plugs 13 connected to it.

[0054] As can be seen from Figure 1B and in the enlarged section of Figure 1C, the tear-off bolt 6 has a first region 14 which is firmly connected to the first part 3 of the overload unit, a second region 15 which is firmly connected to the second part 5 of the overload unit and an intermediate region 16 which is provided with a material taper. In the normal operating state, as shown in Figures 1A-1C, the first part 3 and the second part 5 of the overload unit are held together by the tear-off bolt 6, so that it does not break in the intermediate region 16 between the two regions 14 and 15, as long as the tensile stress between the two parts 3 and 5 of the overload unit caused by the tensile force of the cable guide unit 4 does not exceed the predetermined first tensile stress.

[0055] The fastening of the tear-off bolt 6 to the first part 3 and to the second part 5 of the overload unit is self-explanatory from Figures 1B and 1C.

[0056] As can be seen in particular from Figure 1B, the second part 5 of the overload unit has a pull rod 17 extending in the longitudinal direction L, which is connected to the first part 3 via the tear-off bolt 6 and is firmly connected to the cable guide unit 4 at its end pointing in the longitudinal direction L.

[0057] A tube 18 arranged on the first part 3 of the overload unit is provided to guide the pull rod 17. When the tear-off bolt 6 is separated from the first part 3 and the second part 5 of the overload unit, the pull rod 17 is freely movable in the longitudinal direction L within the tube 18.

[0058] The first component 7 is essentially plate-shaped and is arranged with the tube 18 at its end pointing in the longitudinal direction L (the lower end in the drawing). The design of the first component 7 of the exemplary embodiment under consideration is shown in detail and is self-explanatory in Figure 3C.

[0059] The second component 12 is also essentially plate-shaped and is arranged on the tie rod 17 so as to encompass it. The design of the second component 12 of the exemplary embodiment under consideration is also shown in detail and is self-explanatory in Figure 3C.

[0060] As shown in Figures 1A and 1B, a fastening unit 19 is further provided on the pull rod 17, with which end regions 20 of the electrical cables 8 guided in the cable guide unit 4 are held stably.

[0061] The second component 12 and the fastening unit 19 are attached to a bushing 21 which is firmly connected to the tube 17 of the second part 5 of the overload unit.

[0062] As can be seen in more detail from Figure 3C, the first component 7 and the second component 12 are connected by a separation unit comprising a plurality of tear-off rods 22, of which only one tear-off rod can be seen in Figure 3C. The tear-off rods 22 are fastened at one end (upper in the drawing) to the first component 7 and at their other end (lower in the drawing) to the second component 12. They are designed in such a way that they tear when a predetermined second tensile stress occurs between the components 7 and 12, which is smaller than the first predetermined tensile stress between the two parts 3 and 5 of the overload unit, so that the second component 12 is separated from the first component 7 and the pull rod 17 moves under the tensile force acting on it from the cable guide unit 4 (downward in the drawing).

[0063] The cable guide unit 4 shown in Figures 1A and 1B is designed as an energy guide chain and has a flexible support strand 23 with high tensile strength and a number of guide bodies 24 arranged one behind the other in the longitudinal direction of the support strand 23, wherein adjacent guide bodies 24 are spatially deflectable relative to one another. The guide bodies 24 each comprise a central part 25 with a fastening device for fastening to the support strand 23 and an outer part 26 with circumferential elements that delimit a receiving area for the electrical cables 8 guided in the energy guide chain.

[0064] The supporting strand 23 is firmly connected to an end region 27 of the tension rod 17 pointing in the longitudinal direction L.

[0065] The end region of the cable guide unit 4 shown in Figures 1A and 1B belongs to a hanging strand of the energy guide chain, which can lead, for example, to a drilling rig (not shown in the drawing).

[0066] The device by means of which the tensile force acting on the second part 5 after the first part 3 has been released from the second part 5 of the overload unit can be transmitted from the cable guide unit 4 to the second component 12, has a first stop 28 arranged on the pull rod 17 and a first stop surface 29 arranged on the second component 12, opposite the stop 28 in the longitudinal direction L, which first stop surface 29 is arranged at a predetermined distance from the stop 28 in the normal operating state of the exemplary embodiment. The pull rod 17, which moves freely in the longitudinal direction L with the first part 3 of the overload unit after the connection has been released, can strike the first stop surface 29 of the second component 12 after overcoming the predetermined distance with the first stop 28 and thus transmit the tensile force acting on the pull rod 17 from the cable guide unit 4 to the second component 12.In this state of the embodiment shown in Figures 3A-3C, the tensile stress acting between the two components 7 and 12, which exceeds the predetermined second tensile stress, can lead to the tearing off of the tear-off rods 22 of the separating unit and to a further free movement of the pull rod 17 with the second component 12.

[0067] Furthermore, a second stop 30 is provided on the pull rod, opposite which a second stop surface 31 on the side of the first component 7 facing in the longitudinal direction L lies at a predetermined distance from the stop 30. The second stop 30, like the first stop 28, is designed in the form of a flange extending around the pull rod 17. The second stop 30 of the pull rod 17, which interacts with the second stop surface 31 on the second component 12, brings about an insertion of the pull rod 17 into the tube 18 with a length precisely dimensioned according to the distance for the purpose of arranging the tear-off bolt 6 between the pull rod 17 and a part 32 of the first part 3 of the overload unit which can be connected to the fixed connection 2.

[0068] A shackle 33 is arranged on the part 32 , via which the overload unit can be connected to the fixed connection 2 , pivotable in the transverse direction to the longitudinal direction L .

[0069] If the tensile stress between the two parts 3 and 5 exceeds the first predetermined tensile stress due to an overload, the tear-off bolt 6 breaks in the intermediate region 16, which has the material taper, between the two regions 14 and 15. This state of the exemplary embodiment is shown in Figures 2A-2C.

[0070] Figures 3A-3C show the state of the exemplary embodiment after separation of the two regions 14 and 15 of the tear-off bolt 6 at the breaking point 34 indicated in Figure 2C. As can be seen from Figure 3A, the pull rod 17 has moved a short distance, which corresponds to the predetermined distance between the first stop 28 arranged on the pull rod and the first stop surface opposite the stop on the second component 12, in the longitudinal direction L relative to the first part 3 of the overload unit. In this state, the stop 28 bears against the first stop surface 29 with the tensile force from the cable guide unit 4, the tensile force being transmitted to the second component 12 and the tear-off rods 22 extending between the second component 12 and the first component 7, as shown in more detail in Figure 3B.

[0071] As long as the resulting tensile stress between the first component 7 and the second component 12 does not exceed the second predetermined tensile stress and the tear-off rods 22 of the separation unit do not tear, no tensile force is transmitted to the cables 8 extending from the cable guide unit 4 and the plugs 13 connected thereto.

[0072] If the separation process begins due to the further movement of the pull rod 17 in the longitudinal direction L due to the tensile force exerted on the pull rod 17 by the energy guide unit 4, the tear-off rods 22 of the separation unit between the first component 7 and the second component 12 break. This state of the exemplary embodiment is illustrated in Figures 4A and 4B. The pull rod 17 now moves far enough in the longitudinal direction L that the cables 8 extending from the cable guide unit 4, along with their plugs, are pulled out of the first connector parts designed as sockets.

[0073] The final complete separation of the second part 5 from the first part 3 of the overload unit of the isolating device 1 and thus from the fixed connection 2 is shown in Figures 5A and 5B of the drawing.
