Description

The invention relates to a cable guide device according to the preamble of claim 1 and to a power supply system according to the preamble of claim 14.

From the DE 20 2006 009 750 U1 a container loading crane is known, on which a cable cable drum is provided for winding and unwinding a cable. In this case, the cable is connected to a stationary feed point, opposite the loading crane moves in a longitudinal direction. Depending on the travel position, the cable of the cable cable reel is rolled up or down. This has the disadvantage that the cable crane is firmly bound to a route along which it moves forward and backward in the longitudinal direction. For a long time, therefore, the cranes were mounted on rails and firmly connected to a feed-in point.

Since cranes are increasingly not only to move along a single container stacking place, but also between laterally and longitudinally staggered different stacking locations, they can no longer be firmly connected to a single, the respective container stacking space associated feed point. Rather, they must be flexibly connectable to different feed points.

To make this possible, the WO 2014/131826 A1 a device for automatically connecting a crane with an electrical power supply, wherein the connecting cable carried on the crane is provided at the end with a plug which is inserted into a buried in a ground hole docking station. In this case, the docking station has two spaced-apart vertical bars, which penetrate into guide openings of the plug during insertion of the plug into the docking station. Further, there is provided an automatic latch in the ground hole to fix the plug to the docking station.

The umbilical cable projects vertically upward from the docking station and, when the crane moves farther from the docking station, stretches down the length of the floor alongside the crane. In this case, the cable should be bent as evenly as possible and not be less than a minimum bending radius of the cable. Furthermore, a strain relief is provided in order not to damage the electrical leads conducted therein during pulling or rolling up of the cable. Therefore, in the known device, a cable carrying arrangement is additionally entrained, around which the cable coming from the plug in the ground is laid. The cable management assembly is dropped off along with the connector at the docking station. This has the disadvantage that either an operator has to lay the cable around the cable support assembly, or the cable must already be rolled on it before. In addition, the cable support assembly is complex and builds large and heavy, so that the device for settling and receiving the plug and the cable support assembly must be designed sufficiently robust and strong drive. Also, the entire arrangement to be carried on the crane is heavy and thus increases the weight of the crane, so that its travel drive must be designed stronger. In addition, this arrangement is large, so that it requires a lot of space on the crane and increases the width of the crane.

The object of the present invention is therefore to eliminate the abovementioned disadvantages and to simplify the automatic connection of a cable with a feed device arranged at the bottom and to allow gentle guidance and storage of the cable, in particular the risk of kinking or excessive bending of the cable Conduit cable during the procedure of the electrical load to reduce.

In 1 is a known crane 1 for converting containers stored on a container piling place 2 as used on large transfer plants, especially in ports. The crane 1 can on wheels 3 . 3. ' in a direction of travel F proceed in a tram next to the container piling place, which runs generally parallel to the parked containers 2. As a rule, several such container stacking sites are arranged side by side and optionally also one behind the other in transfer plants, whereby the crane 1 and also other cranes can be moved between the individual container stacking locations.

To the crane 1 and the electrical installations installed thereon, eg the motors for lifting and moving the containers 2 as well as the electric traction drives of the wheels 3 . 3. ' be supplied with electrical energy, and / or possibly data from and to the crane 1 to transfer is on the outside of the crane 1 a cable cable drum 4 arranged, from that an electrical line cable 5 Can be rolled up and down in a storage direction, according to the travel path of the crane 1 in the direction of travel F , Usually, the storage direction and the direction of travel are correct F coincide or at most slightly different from each other, since the cable 5 preferably parallel to the direction of travel F is filed. The filing of the cable 5 takes place according to the travel path of the crane 1 , which over the length of the travel usually also slightly different from the ideal, parallel to the containers 2 deviates from the running line. In this respect, "parallel" here and in the following means no exact mathematical parallelism at any point in the travel path, but that the line cable 5 is stored in the context of the driving and filing inaccuracies next to the container stacking place. The above is known per se.

At the freely hanging down end has the cable 5 as a connector 6 respectively. 106 trained connecting element, which for storage on the ground as well as for catching on the cable drum 4 by means of a crane 1 arranged cable guide device 7 or 107 clean and can be performed as stress-free.

In the detailed schematic three-dimensional view of a first embodiment in 2 is again a section of the crane 1 and the wheels 3 . 3. ' shown diagonally from the side. There is also the cable management device 7 shown in detail with the cable 5 clean and can be stored with the least possible force and voltage entries on the ground. The cable management device 7 has two opposite and in the direction of travel F of the crane 1 staggered, down-widening roll bends 8th . 8th' on. In the roll bows 8th . 8th' are a variety of freely rotatable longitudinal guide rollers 9 . 9 ' provided on which the power cable 5 can be guided along with as little friction as possible. In the lateral direction H transverse to the direction of travel F , the leadership of the cable is done 5 by means of two side guide rollers 10 . 10 ' which are above the roller arches 8th . 8th' are arranged and connect them in the present embodiment, but this is not necessary. At the in 2 right roller 8 'is at the bottom of a sensor unit 11 whose function will be explained later. The sensor 11 but could also be at one point of the cable management device 7 or on the crane 1 be arranged, and could also be wirelessly connected to the controller.

To connect the connector 6 with a not drawn in detail electrical power supply is a stationary next to the tramline of the container crane 1 arranged feeding device 12 with a connecting device arranged there 13 intended. The feeding device 12 has two in the present case as plug connections 14 . 14 ' trained connections, which by means of two as swivel plates 15 . 15 ' trained connecting parts about axes of rotation D . D ' (please refer 7 ) rotatable on bearings 16 . 16 ' are articulated. Camps 16 . 16 ' are on the ground or a mounted on the ground fastener, in particular a mounting plate 17 , attached, which in turn is usually mounted on a solid foundation. The function of rotatable storage will be described later on 7 described in detail. But it can also be provided more or less plug-in connections to a feed device.

The connection device 13 has a manipulator 18 which is for gripping and actively moving the connector 6 and for establishing a connection of the connector 6 with the connector 14 is trained. In this case, the manipulator 18 has a manipulator base 19 on, on which a lower manipulator arm 20 with four lower arms 21 . 21 ' . 21 " is articulated, of which in the 2 to 6 two completely and one partially hidden are visible. The manipulator arm 20 can be moved over a lower manipulator drive 22, which the sub-arm 21 " and preferably also the partial arm 21 'rotates.

At the other, upper end are the lower four arms 21 . 21 ' . 21 " then so with a cross-shaped connector 23 connected to that part arms 21 . 21 ' 21 " form a first parallelogram. Next is an upper manipulator arm 24 which, with two upper manipulator arms 25 . 25 ' on two others, to the joints of the lower arms 21 . 21 ' . 21 '' crosswise offset joints of the connector 23 is hinged. At their front, upper ends are the manipulator arms 25 . 25 ' again connected in a parallelogram manner. The upper part arm 25 ' Can via an upper manipulator drive 26 be rotated around its lower hinge axes.

At its front upper end is the upper manipulator arm 24 with a gripping device 27 for the connector 6 equipped to the connector 6 by means of the only in the horizontal feed direction H and vertical feed direction V movable manipulator 18 clean opposite the plug connection 14 to be able to position. The gripping device 27 has a funnel-shaped insertion opening 28 on to the connector 6 as in 4 shown to be able to grab and move safely. This will be explained in detail later.

To the connector 6 so opposite to the only in the horizontal direction of delivery H transverse to the direction of travel F of the crane 1 movable manipulator 18 to position so that the gripping device 27 the connector 6 is sure to grab a signal mast 29 next to the connection device 13 assembled. The signal mast 29 has a positioning element designed as an identifier plate 30. The on in 2 right, lower end of the roll bow 8th arranged sensor unit 11 detects whether the identifier plate 30 faces the sensor unit 11 is in a position in which the manipulator 18, the connector 6 can grab. If so, the gripping action is by the manipulator 18 triggered, the different distances in the horizontal feed direction H can balance out to a certain extent.

For example, it can be checked whether the identifier plate 30 in the measuring range of the sensor unit 11 or not. So can the identifier plate 30 a large-scale QR code and the sensor unit 11 have a very narrow measuring range within which the QR code must lie. Alternatively or additionally, the Identifier plate 30 also have a reflector film with known dimensions and position, in which case with the sensor unit 11 preferably, the distance to this is measured. Once the beginning of the reflector film is detected, then from the known dimensions, the position of the crane 1 or the cable management device 7 be determined against the manipulator 18. The distance measurement can also serve the connector 6 quickly and with the closest possible distance through the manipulator 18 to be able to grab.

Because the insertion opening 28 is funnel-shaped, a certain offset of the connector 6 in the direction of travel F even with not exactly exact positioning of the crane 1 with respect to the insertion opening 28 be compensated.

To the driver or operator of the crane 1 the clean positioning and possibly the securely established connection between connector 6 and plug connection 14 Signaling is at the top of the signal tower 29 a signal light 31 attached with the classic traffic signal colors red, yellow and green clearly visible. Red then indicates that no connection has yet been established, yellow the connection establishment and green the connection established and the retraction of the manipulator 18 So the release for the further procedure. But it can also other colors or flares such as slow and fast flashing o.ä. be used. Alternatively, the driver through the signal light 31 also be displayed, whether at the feed facility 12 another plug connection 14 . 14 ' is free or not: red then signals none and green a free plug connection, while yellow then signals that at the feed device is currently establishing a connection.

The process of gripping and connecting the connector 6 with the connector 14 will be exemplified below 3 to 6 described.

In 3 is the crane 1 already in relation to the connection device 13 driven favorable position and the manipulator arm 18 has the connector 6 already gripped with the gripping device 27. Before, the manipulator moves 18 with the gripping device 27 on the cable 5 above the connector 6 to and surrounds these. Then the gripping device moves 27 from above via an upper, cylindrical gripping part 38 of the connector 6 up to an unrecognizable stop down until a gripper lock the connector 6 at the gripping device 27 finds.

In this case, the gripping part 38 one in 2 easily recognizable centering funnel 39 on, in the opposite, in the funnel-shaped insertion opening 28 arranged centering pins 40 engage. It is in 2 on the outside of the gripping device 27 in its position indicated centering pin 40 shown. This can advantageously be achieved that of the gripping device 27 held connector 6 is aligned so that it clean on one of the plug connections 14 . 14 ' can be plugged.

Then the manipulator moves 18 , as in 3 shown by rotation of the upper Manipulatorarmantriebs 26 and possibly the lower Manipulatorarmantriebs 22 the connector 6 via the connector 14 so that only in 6 recognizable connector opening 32 of the connector 6 aligned with the outer contour of the connector 14. Subsequently, the connector is 6 by means of the manipulator 18 via the plug connection 12 slipped over and releasably connected to a connector lock not shown in detail later, as shown in detail 4 recognizable. It is via the plug connection 14 also an electrical connection between one with the plug connection 14 connected electrical power supply of the container stacking place and the connector 6 of the crane 1 and thus manufactured with its electrical supply network. Likewise, a data connection, for example an electrical or optical data transmission, can thus be produced, for example by providing detachable plug connections.

Due to the double parallelogram guide of the manipulator 18 can be advantageously ensured that the gripping device 27 not changed their inclination angle during their movement with respect to the connector 14. Thus, the connector moved by the gripping device 27 becomes 6 not tilted from the ideal position shown in the drawings, so that the line cable 5 not bent very much or even bent. Instead of a parallelogram, the manipulator 18 but also be designed differently to ensure this, for example, by using a robot with at least one robot arm and a gripping device arranged thereon or in any other, familiar to those skilled manner. For example, two linear telescopic arms or extensions, one horizontal and one vertical, may also be used.

Then, as in 5 shown, the Greifarretierung the gripping device 27 dissolved and the manipulator 18 by rotation of Manipulatorarmantriebe 22 . 26 from the cable 5 and the connector 6 after in 5 right from the crane 1 moved away. Subsequently, with the signal light 31 for the operator of the crane 1 indicated that the connection between connector 6 and plug connection 14 built and the manipulator 18 is free, the crane 1 So from connecting device 13 drive away and start his normal operation. In the present embodiment, the connecting device 13 at the entrance of a tram for the crane 1 arranged so that the drive along the container stacking place in the 2 to 6 runs diagonally right above. The connecting device 13 can also be arranged elsewhere.

As is known from the prior art, it is important for the longest possible service life of the cable 5 that it is as rare as possible, preferably not bent over the allowable minimum bending radius out or even completely kinked.

One aspect of the present invention therefore has for its object an improved guidance of the cable connected to a feed device 5 to allow and in particular the risk of kinking or excessive bending of the cable 5 in the process of the electrical load, in particular crane 1 , to reduce.

For this purpose, the invention sees how particularly well in 6 and 7 recognizable, before, that the plug-in connections 14, 14 'about a transverse to the direction of travel F and preferably parallel to the floor axis of rotation D respectively. D ' are rotatably arranged. Then drive the crane 1 with the cable 5 from the connection position 2 in the direction of travel F away to the right, as in 6 indicated, the cable becomes 5 due to the direction of travel F swiveling plug connection 14 not or hardly bent or kinked, but runs from the plug connection 14 largely straight and in the pulling direction of the cable 5 to the cable management device 7 out. Removes the crane 1 then further from the feeder 12 and connecting device 13 , the cable becomes 5 Piece by piece in a known manner next to the road of the crane 1 stored. In contrast to the prior art but in the present embodiment, the plug connection 14 so far tilted that the connector 6 slightly down and the power cable 5 with little or no curvature of the connector 6 coming to the ground is dropped.

Thus, the cable becomes 5 During the entire filing process only slightly curved, which allows a gentle routing, the life of the cable 5 extended and thus the reliability of the system is increased.

The use of the shown in the drawings and described above pivot functionality of the connector 14 is also for systems with permanent connection of the cable 5 with the feeding device 12 possible, so that even then the benefits of improved cable routing result.

This in 7 shown detail of the connection device 13 shows here an additional plug connection 14 ", which in the operation but exactly the plug connections 14 . 14 ' equivalent. Since these are identically formed, the invention is preferred below using a plug connection 14 explained. The two other plug connections 14 ' . 14 " as well as their parts are denoted by the corresponding reference numerals as in the connector 14, possibly supplemented by one or two apostrophes.

The plug connection 14 has a plug connection housing 33 in which the electrical connection elements for an electrical power connection and / or a data connection connection (not visible) are arranged.

To prevent ingress of moisture, dust, water, rain etc. from above on the electrical connection elements, the plug connection housing has 33 at his in 2 shown hibernation top end a cover 34 which, via a pair of hinges 35 rotatably on the plug connection housing 33 is articulated. The cover 34 is spring-operated in a conventional manner held in the closed position or moved back from an open position to the closed position.

To the cover 34 when placing or attaching the connector 6 to open automatically are with the cover 34 Actively connected opening tabs 36 on the side of the hinges 35 provided, which project outwardly beyond the plug connection housing 33. A corresponding stop in the connector 6 , in particular the corresponding edge of the connector opening 32 , then presses the opening tabs 36 when putting on and slipping over the connector 6 on the connector housing 33 down so that the cover 34 moved upwards. As a result, the electrical connection elements of the plug connection 14 Approved. Subsequently, the connector is 6 then even further moved down and located in the connector 6, here male electrical and / or data connection elements can be connected to the corresponding, here female connection elements in the connector housing 33 against external influences such as wind, water, rain, etc. connected. Also, by the cover 34 Prevents operators or unauthorized persons from gaining direct and unprotected access to receive the connection elements, in particular to the electrical connection elements.

To the swivel plate 15 and thus the plug connection 14 in the in 2 to 5 can hold a shown in rest position, an in 7 shown stop 37 at the camp 16 be provided for the pivot plate 15. In the embodiment shown, the plug-in connection 14 then remains weight-dependent in the rest position. In an advantageous embodiment, not shown, a spring force on the pivot plate 15 act to return the connector 14 in its rest position when it is not connected to the connector 6.

In an alternative embodiment of the connecting device 13 which preferably also along a road of the crane 1 can be arranged, are the plug connections 14 . 14 ' Advantageously designed so that they are arranged around a preferably centrally arranged axis of rotation D in both directions of the direction of travel F can rotate, so a filing of the cable 5 both on one side and on the other side of the plug-in connections 14 . 14 ' can be done. Again, a holding device is advantageously provided, which ensures that the non-connected plug-in connection in the for connecting the connector 6 suitable, advantageously pointing upward direction. Preferably, the plug-in connection 14 while doing so on the bottom plate 17 be locked until the connector 6 safely with the connector 14 connected is. Such an embodiment will be described later and is independently realizable for the skilled person.

The 8th to 28 show alternative embodiments of parts of in 1 basically shown energy transmission system, in particular with a modified feed device 112 , Connecting device 113 and cable management device 107 , Since these are in many parts the same or similar structure as in the 2 to 7 shown embodiment, corresponding parts with corresponding reference numerals, respectively supplemented by the number "100" are used. Also, the differences are discussed above, so the comments on corresponding parts in the first execution 2 to 7 accordingly also for the alternative embodiments of 8th to 28 apply and vice versa, unless otherwise stated.

At the in 8th shown feeding device 112 is also a control cabinet 148 shown in which the electrical power unit sits and to the in 16 indicated supply and data cables 149 lead, which through cable penetrations 150 . 150 ' . 150 ' (please refer 16 to 18 ) in the control cabinet 148 to lead.

In the 8th to 13 Operation of the energy transfer system shown basically corresponds to the in 2 to 7 shown. So will in 8th the cable 5 with a connector 106 again so opposite the manipulator 118 positioned that a gripping device 127 the connector 106 can move when moving in the horizontal feed direction H. Subsequently, the connector is 106 something drained, leaving him the manipulator 118 grip in the manner described above with the gripping device 127 and in which to be placed on the plug connection 114 to bring the intended position. The plug connection 114 is like the plug connection 14 designed and has in particular a plug connection housing with a movable cover.

From the position in 9 becomes the connector 106 then again led to a plug-in connection 114, on which it is placed in the manner described above, as in 10 to 11 shown. This is the connector 106 locked again to the feeder 112, which is described below with reference to 19 and 20 will be explained in detail. Subsequently, as in 12 shown the manipulator 118 detached from the connector 106 and moved to its rest position.

In 13 is shown that by the method of not shown crane 1 the connector 106 with plug connection 114 again around the axis of rotation D from the in 12 shown rest position is pivoted.

The in 8th to 13 shown alternative signal mast 129 know two oblique feet 151 on, at those at the front, free end of a boom 152 carries an alternative identifier plate 130. Accordingly, at the cable management device 107 an alternatively formed sensor 111 arranged, which for detecting the identifier plate 130 is used. In this case, advantageously, a distance sensor 111 be used with a narrow measuring range. The identifier plate 130 has a beneficial in a horizontal feed direction H front central area 153 and in the direction of travel F adjoining on both sides, opposite the central area 153 in horizontal feed direction H to the rear, so from the crane 1 away, offset edge areas 154 . 154 ' , Preferably, the identifier plate 130 has a reflector, for example a reflector foil, in order to reflect the signal emitted by the distance sensor 111 as well as possible. Possibly. but also again the identifier plate 31 from the next Embodiment described above.

To the connector 106 central to the central area 153 to position, the distance sensor detects 111 when starting in the direction of travel F from in 8th right or left first the distance to one of the two rear edge areas 154 . 154 ' , If he then continues in the direction of travel F to the central area 153 goes, he detects the spatial detection of the central area 153 a sudden reduction in distance and thus the beginning of the front central area 153 , About the known geometric dimensions, in particular the extent of the central region 153 in the direction of travel F , then the still necessary travel in the direction of travel F be determined to the connector 106 as exactly as possible on the gripping device 127 to position.

In this way, the positioning of the connector 106 be simplified relative to the manipulator 118, wherein only on the cable guide device 107 an active sensor 111 can be arranged while it is at the identifier plate 130 to act as a passive element. The identifier plate 130 can also have other configurations, which can detect a clearly defined change in the distance by the sensor 111. For example, the central area can be offset to the rear and the edge areas closer to the crane 1 , In particular, in a simplified embodiment, the edge regions 154, 154 'can be omitted, so that only the transition from the not at all or only poorly reflecting environment to the well-reflecting region of the identifier plate has to be determined. Also, if necessary, the central area 153 and the adjoining border areas 154 . 154 ' if they are offset from each other in the horizontal feed direction H or not, have different good reflective properties, so that a distinction is made possible by the degree of the reflected signal strength.

Next, the design differs 8th to 28 by the design of the swiveling plug-in connections 114 from the execution in 2 to 7 , It will therefore be discussed below again mainly on the differences, while for the same or similar components turn the above to 1 corresponding statements apply accordingly. Again, due to the identical design of the plug connections 114 . 114 ' . 114 ' the invention further based on the plug connection 114 unless otherwise specified. Accordingly, this version also apply to the other plug connections 114 ' . 114 ' ,

How out 16 to 18 shows, is the plug connection 114 again with a swivel plate 115 around a rotation axis D on a mounting plate 117 around a warehouse 116 rotatably mounted. The plug connection 114 but could also be arranged directly rotatable on the mounting plate 117. The rotation axis D runs substantially horizontally and in the direction of the horizontal feed direction H of the manipulator 118 , The attachment plate 117 is above one in the foundation 155 provided pit 156 arranged.

As in 16 and 18 recognizable, flow into the pit 156 from the control cabinet 148 coming cable glands 150 in which the in 16 indicated power and data cables 149 run. These cables 149 each extend through one below the plug connection 114 arranged connection opening in the bottom plate 117 to the bottom of the plug connection 114 where they are with the here female connection elements of the plug connection 114 electrically connected, as in 20 indicated.

To when pivoting the connector 114 the cable 149 arranged on its underside to be able to guide cleanly and to be able to encapsulate in relation to the environment, inter alia also for protection against contact, is on the underside of the plug connection 114 , in particular the pivot plate 115, one with the pivot plate 115 around the axis of rotation D movable first protective housing 157 provided. At the bottom of the swivel plate 115 close identically formed, about 100 ° measuring circular sector-shaped side walls 158 . 158 ' as well as the circular arc sides of the side walls 158 . 158 ' connecting end wall 158 ' the first shelter 157 on, as in 15 and 17 good to see. Another front side between the side walls 158 . 158 ' , the front wall 158 ' and the pivot plate 115 remains free and forms an in 18 visible from the front opening 158 '" for the cable gland 150 coming cables 149 ,

The first protective housing 157 runs in a second, firmly on the bottom of the bottom plate 117 arranged, slightly larger, but appropriately trained second Schutzumhausung 159 with circular sector-shaped side walls 160 . 160 ' , a connecting this end wall 160 ' and a frontal opening 160 '" for the cable gland 150 coming cables 149 , Alternatively, but also on the second Schutzumhausung 159 be waived since the first protective housing 157 with lowered swivel plate 115 according to 14 and 16 also a protection for the cables 149 offers.

The cables 149 are dimensioned so long that the in 15 and 17 shown fully folded position of the connector 114 is possible. In the in 14 and 16 shown fully pivoted position of the connector 114 folds or lays the excess cable length of the cable 149 preferably within the protective enclosures 157 . 159 together. Because the cables 149 in the area of protective housings 157 . 159 completely surrounded by these, the cables can 149 when swiveling the plug connection 114 be guided reliably, so that neither damage the cable 149 still a hindrance to the movement of the plug connection 114 is to be feared. Preferably, for guiding the cable 149 an unshown energy chain can be used, which is on the bottom of the pit 156 runs and then in Fig. 17 extends S-shaped upwards

To a not quite exact positioning of the connector 106 opposite the plug connection 114 To be able to compensate is on the narrow end faces of the swivel plate 115 one centering bracket each 161 . 161 ' arranged. These have a lower, vertical guide area 162 . 162 ' on, to which an upper, from the plug connection 114 wayward, slanting entry area 163 . 163 ' followed. With inserted plug connection 114 , such as in 13 shown, embrace the vertical guide areas 162 . 162 ' the connector 106 , whereby an improved positioning, in particular pre-centering of the connector 106 on the plug connection 114 can be achieved.

To accidentally release the connector 106 from the plug connection 114 To prevent what is unfavorable in particular during the transmission of energy, are on the pivot plates 115 . 115 ', 115 "on the front sides of the plug connections 114 . 114 ' . 114 ' each connector locks 164 . 164 ' . 164 ' provided, which in particular in 19 and 20 are clearly recognizable. Due to the identical design of the connector locks 164 . 164 ' . 164 ' is below again only the connector lock 164 unless otherwise stated.

The plug lock 164 in this case has one each through the pivot plate 115 in the area of the connector 106 reaching locking bolt 165 up, over the swivel plate 115 protrudes and an elongated locking head 166 having. Advantageously, on the opposite end face of the connector 114 another, identically designed locking bolt 165a be arranged as in 20 indicated.

In the open position is the locking head 166 aligned so that it into a corresponding, in particular in 24 easily recognizable elongated locking opening 169 on the connector 106 can be pushed through.

If the connector 106 then completely on the plug connection 114 is attached, the locking head 166 and the not shown locking head of the locking bolt 165 a by means of a in 20 shown locking drive 167 via a lever arrangement 168 at the same time from an open position, as in 19 and 20 based on the outer two plug connections 114 . 114 ' shown in an in 19 and 20 at the middle plug connection 114 ' shown to 90 ° twisted closed position still moves. Possibly. but also a smaller or larger rotation can be selected to lock securely. Preferably, the locking drive 167 via a lever assembly 168 at the same time the locking bolt 165 and the opposite locking bolt 165a drive.

Instead of a lever arrangement 168 but also for every locking bolt 165 . 165 ' 165 ' respectively. 165a . 165a ' 165a " a separate locking drive can be provided. Basically, could also be on any plug connection 114 . 114 ' . 114 ' only one connector lock can be provided.

In addition, the plug lock serves 164 in this case, the swivel plate 115 at the bottom plate 117 to fix, if no connector 114 connected. For this, the attacks in 20 lower lever arm, which is the lower, in 19 rear locking bolt 165a drives, in the in 19 and 20 shown fixing position under the bottom plate 117 so that the swivel plate 115 not with the indicated, above the bottom plate 117 extending axis of rotation D from the bottom plate 117 can be swiveled away. In contrast, the fixation of the middle pivot plate 115 ' opened so that it could be tilted. Alternatively or additionally, one of the connector lock 164 independent holder, in particular plug connection lock for releasably securing the plug connection 114 in the rest position on the base plate 117 be provided until the connector 114 and plug connection 114 securely connected.

Another aspect of the invention provides that the line cable 5 For better automatic connection has a special structure. Next can also be advantageous, the connector 6 . 106 be specially designed to grip with the manipulator 18 . 118 and in particular the gripping device 27 . 127 to improve, in both embodiments described above.

This will be explained below in particular with reference to 21 to 24 described in detail.

21 shows a cross section through a cable 5 , for example, slightly above the connector 106 , This shows the cable 5 an outer sheath made of a flexible material 41 on, for example, rubber, PVC or other elastic plastic. The outer jacket 41 surrounds three here symmetrically arranged phase conductors 42 for electrical energy transmission, one in two individual conductors 43 divided protective conductor and a data transmission conductor 44 , in particular an optical data transmission cable. Next is at the core of the line cable 5 a flexible, yet robust carrier 45 provided, for example, an aramid rope or wire rope. The supporting organ 45 is surrounded by a filling material and / or molded parts 46 which a support and holding function for the other ladder 42 to 44 of the cable 5 exercise.

This can be done in the cable 5 arranged sensitive conductors 42 to 44 be relieved of train while the supporting organ 45 decisive for the absorption of the longitudinal forces during winding and unwinding of the cable 5 serves. In addition, in the outer jacket 41 another strain relief 46 be provided, for example, in the outer jacket 41 embedded mesh or tissue.

So that the supporting organ 45 can serve as strain relief, it is in the in 22 to 24 shown in detail, partially disassembled connector 106 attached as described below.

The connector 106 has two connector fairing halves, of which in 22 and 23 in each case only one connector panel half 170 is shown while the other is removed to the inside of the connector 106 to be able to show.

Next is a made of a robust material, in particular a steel sheet, substantially U-shaped support frame 171 provided, which at its free leg ends 172 . 172 'each already mentioned above, designed as a slot locking openings 169 . 169 ' having. The free leg ends 172 . 172 ' connecting middle section 173 of the support frame 171 then has a circular opening 174 on, through which the substantially hollow cylindrical gripping part 138 of the connector 106 from in 22 and 23 is pushed through at the bottom. The gripping part 138 beats with an annular outer flange 175 on the support frame 171 and is fixed there, for example screwed or riveted.

For loads in the longitudinal direction of the cable 5 on the one hand, the strain relief 47 of the outer jacket 41 in the gripping part 138 and / or on the support frame 171 be clamped (not visible). On the other hand is on the annular outer flange 175 of the gripping part 138 a transverse to the longitudinal direction of the cable 5 extending clamping bolt 176 intended. The clamping bolt 176 has a not shown attachment for the support member 45 on, in particular a passage opening through which the support member 45 is pushed through. On the clamping bolt 176 is a spring element, in particular a spiral spring 177 arranged, which with a surrounding clamping bolt sleeve 178 is connected to the one end of the support member 45 is attached. For tensioning the bearing element 45 becomes the clamping bolt 176 initially in its axial direction against the pressure of a stepped end 178 of the clamping bolt 176 sitting spiral spring 177 from an in 22 shown anti-slip 179 pushed out. Then we the clamping bolt 176 repeatedly rotated in the winding, so that the support member 45 with several windings on the clamping bolt 176 is wound up. To prevent the supporting organ 45 unwinds under load, presses the coil spring 177 then the clamping bolt 176 back in the 22 easy to recognize, anti-slip 179 , Instead of the spiral spring 177 can also be used other spring elements, such as disc springs, which the clamping bolt after tightening the support member 45 again reliable in the anti-slip 179 to press. The anti-slip device 179 can advantageously have a knurled inner bore, with which also a knurled end of the clamping bolt 176 interacts.

The different leaders 42 to 44 while being unloaded by the circular opening 174 in the support frame 171 in the area between the free leg ends 172 . 172 of the support frame 171 guided and there with respective, here male electrical connection elements 180 of the connector 106 electrically and mechanically connected. The individual male connection elements 180 are on a connection carrier 181 arranged, which in the from the connector opening 132 to the gripping part 138 extending longitudinal direction, ie also in the longitudinal direction of the cable 5 , held stationary and is floating freely floating transversely to this longitudinal direction.

To the male connection elements 180 To protect against unauthorized touching and other external influences, the connector plug opening 132 through a protective flap 182 locked. The protective flap 182 is spring-operated in the in 21 and 22 shown closed position, but can when placing the connector 106 on the plug connection 114 by the power of the manipulator 118 in the area between the free leg ends 172 . 172 'be folded away.

To the male connection elements 180 of the connector 106 in corresponding female connection elements (not shown) of the plug connection 114 to be able to introduce, are at the connection carrier 181 elongated centering bolts 183 provided with a conical end, which in corresponding centering openings of the connector 114 (not shown) intervene.

In 23 clearly visible is the centering funnel 139 on the gripping part 138 , which in addition to the in 2 to 7 shown embodiment is extended at its lower end slit-shaped in a centering slot. This can be about the in the insertion 128 the gripping device 127 provided, diagrammatically indicated in their position centering mandrels 140 the connector 106 already while gripping with the gripping device 127 as good as possible on the plug connection 114 be aligned.

Next, an in 25 to 28 shown in detail alternative cable management device 107 as an additional function to the in 2 shown embodiment a pendulum swing 184 for better guidance of in 8th to 20 and 25 to 28 graphically not shown line cable 5. Basically, such pendulum rockers are already known, compared to the new is present but the possibility of linear mobility, in particular the linear height adjustment of the pendulum swing 184 , This serves to during the process of the crane 1 completely in the lower position located swingarm 184 for automatically gripping the connector 106 by means of the manipulator 118 all the way up and out of the gripping area of the manipulator 118 to move out and the connector 106 to be able to position correctly.

It is on the cable management device 107 one about a substantially horizontal and transverse to the direction of travel F of the crane 1 aligned pendulum axis P rotatable pendulum mount 185 provided so that the pendulum swing 184 around the pendulum axis P can swing back and forth, as in 27 to recognize.

The deflection of the pendulum swing arm is effected 184 from the vertical S in a conventional manner by the during the process of the crane 1 up or unwound cable 5, which by a at the lower end of the pendulum swing 184 arranged cable guide 186 runs with longitudinally and transversely oriented cable guide rollers. It can be detected by known per se, unspecified Stramm- or Schlappsensoren whether the cable 5 just tight or limp is guided, and then possibly the cable 5 be collected or issued. The cable is preferred 5 by a direction of discharge of the line cable 5 in front of the cable management 186 the swingarm 184 arranged further cable guide out, which advantageously between and / or at the upper end of the two roller bends 108 . 108 ' is arranged. The cable guide can advantageously by the side guide rollers 110 . 110 ' but there are other ways to guide the cable 5 be provided.

To the pendulum swing 184 between the in 25 and 28 To move back and forth shown upper and lower extreme positions, the pendulum swing 184 two in 25 partially broken illustrated, in cross section U-shaped, with their open sides facing each other guide rails 187 . 187 ' on. The guide rail 187 is by means of the pendulum mount 185 attached lateral guide rollers 188 . 188 ' , inner front guide rollers 189 . 189 ' and one on the outside of the middle leg of the guide rail 187 running outer face guide role 189 ' guided. The guide rail 187 becomes laterally from an angled guide plate 190 entrained, on which the outer end-side guide roller 189 ' is arranged. The guide of the guide rail 187 ' is executed accordingly, in 26 that on the pendulum mount 185 opposite side of the cable management device 107 arranged guide plate 190 ' the other guide rail 187 ' with outer face guide roller 189 '" is clearly visible.

Next is at the pendulum mount 185 one with the pendulum swing 184 movable pendulum drive with an electric motor 191 , a 90 ° gearbox 192 and one on one of the pendulum swingarm 184 attached rack 193 meshing drive pinion 194 intended. This allows the pendulum swing 184 in their longitudinal direction to the pendulum holder 185 be moved towards and away from the motor. Alternatively, a direct linear drive or toothed belt drive for extending and retracting the pendulum swing 184 be used.

To the connector 106 for the gripping device 127 clean in the cable management device 107 To be able to position, the pendulum swing moves 184 to the very top, as in 8th to 11 and 28 shown. At the same time or after, the connector becomes 106 about the cable 5 all the way up to the cable management 186 the swingarm 184 drawn.

To the connector 106 even better for grasping through the manipulator 118 in the cable management device 107 To be able to position, are on the roll arches 108 . 108 ' opposing brackets 195 . 195 ' arranged. The headband 195 . 195 ' are essentially horizontal, transverse to the direction of travel F running axes of rotation 196 . 196 ' rotatable and have downwardly extending, rod-shaped holding extensions 197 . 197 ' . 197 ' . 197 '" on which in the in 8th and 28 shown upper position on the connector 106 abut and so twisting or dodging the connector 106 during gripping by the gripping device 127 prevent.

By default, the headband 195 . 195 ' Fed in the in 12 . 25 and 27 shown open retraction position on the roller arches 108 . 108 ' held.

Only when the pendulum swing 184 in the in 8th to 11 and 28 moved upper stop position hit stop rollers 198 . 198 ' on the upper, shorter lever arms of the headband 195 . 195 ' at appropriate stops 199 . 199 ' the cable management 186 so that the lower, longer, approximately L-shaped inwardly bent lever arms of the headband 195 . 195 ' towards each other and to the connector 106 to be moved. The headband 195 . 195 ' can also be configured differently, it is only essential that when starting the pendulum swing 184 or optionally also the connector 106 even the headband 195 . 195 ' for installation on the connector 106 to be moved.

As in 27 recognizable serve the cable guide stops 199 . 199 ' in addition, as actuators for the unspecified Straumsensoren when the pendulum swing 184 is pulled into their laterally completely deflected position.

The present invention is the sensor described above 111 advantageous on the pendulum swing 184 arranged, whereby he over an energy chain 200 is powered and data-technically connected to the control of the crane. The sensor 111 but could also be at one point of the cable management device 107 or on the crane 1 be arranged, and could also be wirelessly connected to the controller.

29 and 30 show an alternative embodiment of a cable management device 207 which is essentially made up of two things from the one in 25 to 28 distinguished embodiment, namely on the one hand, the design of roller arches 208 . 208 ' and longitudinal guide rollers 209 . 209 ' respectively. 209 ' and on the other hand an alternative drive 291 a swingarm 284 , Therefore, in the cable management device 207 again corresponding reference numbers, in each case supplemented by the number "200" used. Also, the differences are mainly discussed, so that explanations to corresponding parts in the first execution after 2 to 7 and the second embodiment according to 8th to 28 accordingly also in the 29 and 30 shown embodiment, unless otherwise stated.

These are outer longitudinal guide rollers 209 ' in the outer, lower area of the roll bow 208 ' wider than the inside, upper part of the roll bow 108 ' arranged inner longitudinal guide rollers 209 ' of the roll bow 208 ' , This has the advantage that when outputting the cable 5 not quite parallel to the direction of travel F of the crane 1 the cable 5 in the outer area of the roll bow 208 may have a little more lateral offset, so one from the top of the cable management device 207 seen slightly oblique orientation of the wire cable 5 to the longitudinal extent of the roll bow 208 ' can have. For this purpose, the frame of the roll bow 208 ' at its outer, lower, outwardly facing end preferably a larger distance between two opposite walls, between which the longitudinal guide rollers 209 ' are fixed on, as in the area of the inner, narrower longitudinal guide rollers 209 ' , The second, other roll bow 208 is accordingly reversed formed, otherwise apply to the comments on the roll bow 208 ' corresponding.

Next will be in place of the in 25 to 28 shown rotary electric motor 191 a direct linear drive 291 for longitudinal movement of the pendulum swing arm 284 used. Here is the pendulum mount 285 slightly extended upwards, as well as the angled guide plate 290 , Preferably, the drive part of the linear drive 291 on the angled guide plate 290 or the pendulum holder 285 support while a movable piston rod 201 of the linear drive 291 on the moving part of the pendulum swingarm 284 is attached. Preferably, the output-side end of the piston rod 201 on in 29 and 30 lower end of the moving part of the pendulum swing arm 284 , in particular a U-shaped guide rails 287 to be appropriate. To start the pendulum swing 284 then becomes the piston rod 201 moved upwards.
