    Description: The present invention relates to a cable winch arrangement which comprises at least one cable drum rotatably mounted about a drum axis for winding and / or unwinding at least one cable and a support structure and a spindle drive for displacing the cable drum relative to the support structure, the spindle drive being one Has a spindle extending along a spindle axis, and a rope run-off point of the at least one rope, on which the rope runs tangentially from and / or runs off the rope drum, is at least essentially stationary with respect to the support structure. Furthermore, the invention relates to a crane, a travel drive with at least one cable winch arrangement and a rake cleaning device.
    Cable winch arrangements are used in various embodiments for winding and / or unwinding at least one cable, the at least one cable usually being wound up and / or unwound from the cable drum on a circular cylindrical cable drum, which is also called a winch. The at least one rope is usually spiral, in particular helical or helical, can be wound or wound on the rope drum. It is characteristic of common rope winch arrangements that the rope run-off point of the at least one rope, on which the rope runs tangentially onto or from the rope drum, is variable in position. That is, the rope run-off point moves along a direction parallel to the drum axis of the rope drum while the rope is being wound or unwound. This movement could also be described as a “walking of the rope run-off point on a drum jacket of the rope drum during the rotation of the rope drum. The "wandering of the rope drain point along the drum jacket of the rope drum means that a freely hanging rope end of a rope partially wound onto the rope drum, to which, for example, a load is attached, is moved with the rope drain point parallel to the drum axis, which is why it is lifted during the lifting or Lowering movement of the rope also leads to a mostly undesirable, superimposed displacement of the load in a direction parallel to the drum axis.
    In order to steer the at least one rope running from the rope drum in a predetermined direction, rope pulleys are often used. Rope pulleys have a circumferential rope groove in which the rope is guided. An essential parameter of a rope pulley is the lateral run-on angle of the rope when the rope runs in or out of the rope groove of the rope pulley. The lateral run-on angle is the angle of the lateral deflection of the rope with respect to a groove plane in which the rope groove of the rope pulley is arranged. A large side run-on angle, e.g. more than 4 °, has a significant impact on the lifespan of the rope. In order to limit the lateral run-on angle, rope pulleys must therefore be arranged at a relatively large distance from the rope drum.
    Document DE 101 35 034 C1 discloses a cable winch arrangement with a displacement unit which longitudinally displaces the cable drum in synchronism with the winding and unwinding of the cables in such a way that the respective cable drain points, based on a hoist frame, are always in the same place. As a result, the lateral run-on angle of the rope on the respective rope pulley can be kept constant. In one possible embodiment variant, the displacement unit has a threaded spindle drive for displacing the cable drum, the threaded spindle drive being coupled to the cable drum axis via a toothed belt.
    The object of the invention is to provide an advantageous winch arrangement of the type mentioned, which can be easily formed.
    According to the invention this is achieved by a winch arrangement with the features of claim 1.
    In the cable winch arrangement according to the invention it is provided that the spindle axis is arranged coaxially to the drum axis of the cable drum. This means that the spindle axis 1/25

    Patentamt se lies on a common axis with the drum axis of the rope drum. A simple construction of the cable winch arrangement can thereby be realized.
    In the sense of the invention, the spindle drive is a screw gear. In particular, the spindle drive according to the invention can be a trapezoidal screw drive, ball screw drive, roller screw drive with roller return, planetary roller screw drive, steep screw drive etc. The spindle drive connects the support structure to the cable drum, an adjustment of the spindle drive leading to a relative displacement of the cable drum with respect to the support structure. The spindle drive is adjusted in the direction of the spindle axis. Since the drum axis of the cable drum is arranged coaxially with the spindle axis, the relative displacement of the cable drum with respect to the support structure also takes place in a direction parallel to the drum axis or to the spindle axis.
    By the expression, according to which the rope drain point is “at least essentially stationary,” it is meant that the rope drain point is at least substantially immovable relative to the support structure during the winding or unwinding of the rope. The point at which the rope runs off is, in particular, the point at which a longitudinal center axis of the rope changes from a helical orientation - which a section of the rope wound on the rope drum takes up - into a tangential direction - in relation to the drum jacket of the rope drum. The rope run-off point could also be referred to as a rope run-up point or a rope run-up and run-off point. In this context, the expression “at least essentially means that the rope run-off point between a completely unwound state of the rope and a completely wound state of the rope advantageously moves parallel to the drum axis by less than the amount of a rope diameter.
    The term support structure is to be understood broadly in the sense of the invention. The support structure can be, for example, a load-bearing component of a trolley of a crane, a base frame of a screen cleaning device or a running gear. In any case, the support structure serves to support the cable drum and to absorb the cable forces acting on the cable drum. The cable drum can be supported on the supporting structure or can be connected to the supporting structure in some other way. For example, it is also conceivable and possible for the cable drum to hang on the support structure.
    The cable drum is advantageously rotatably mounted on a storage rack. The storage rack could also be called a support frame or drum frame. It is advantageously provided that, apart from the rotation of the rotatably mounted cable drum, no relative movement between the cable drum and the storage frame is possible. That that the storage rack can advantageously be moved together with the cable drum relative to the support structure. In order to reduce the friction between the bearing frame supporting and supporting the cable drum and the supporting structure when the cable drum or the bearing frame is displaced relative to the supporting structure, the cable winch arrangement can have a sliding guide or a roller guide.
    It is preferably provided that the spindle, at least in one end position, extends at least in sections into a cavity of the cable drum. A particularly compact design of the cable winch arrangement can thereby be realized. The cable winch arrangement advantageously has two end positions, the end positions limiting the travel of the cable drum relative to the support structure, in mutually opposite directions aligned parallel to the spindle axis or to the drum axis.
    The cavity of the cable drum could be completely limited in the radial direction with respect to the drum axis by a drum jacket of the cable drum. Furthermore, the cable drum could have two mutually opposite drum flanges, which limit the cavity in the axial direction with respect to the drum axis.
    It is particularly preferably provided that the spindle of the spindle drive is arranged in one of the end positions over at least 50%, preferably at least 70%, of the length of the spindle in the cavity of the cable drum.

    Patent Office In a preferred embodiment, the spindle has an external thread with a pitch, the pitch of the external thread corresponding at least to the rope diameter of the at least one rope. The pitch refers to the distance between two threads in a direction parallel to the spindle axis. The pitch gives the measure of the adjustment of a spindle nut of the spindle drive in relation to a direction parallel to the spindle axis when the spindle nut is rotated relative to the spindle by 360 °, i.e. by one turn. For the purposes of the invention, the rope diameter means the outside diameter of the rope. A rope, viewed in a cross section orthogonal to the longitudinal center axis of the rope, often has a cross section deviating from the circle. The diameter of a smallest circumference encompassing the cross section of the rope could also be referred to as the rope diameter.
    It is preferably provided that the cable drum has a drum shell with at least one spiral groove for receiving at least one of the cables, a pitch of the spiral groove corresponding to the pitch of the external thread of the spindle. The at least one spiral groove of the drum shell advantageously extends helically along the drum axis, in particular around the drum axis. The at least one groove of the drum shell could also be referred to as helical or helical. The at least one groove can extend helically over the entire longitudinal extent of the drum shell. However, it is also conceivable and possible for the drum shell to have a plurality of grooves which, based on the direction of the drum axis, can be arranged one behind the other and at a distance from one another. In other embodiments, it is conceivable and possible that the spiral grooves are interleaved, i.e. that the pitch of each spiral groove is greater than the rope diameter of the at least one rope. For example, the pitch could be an integral multiple of the rope diameter. It is e.g. It is possible that four congruent spiral grooves, each of which has a pitch that corresponds to four times the rope diameter, are offset by a quarter turn in relation to a circumferential direction of the drum axis of the rope drum. However, this is only a concrete embodiment and can be transferred to any number of ropes. The entirety of the grooves of the drum shell could also be referred to as multi-start grooving. In a possible other embodiment, an outer surface of the drum shell could be circular cylindrical, i.e. be essentially smooth. This means that a grooved drum jacket is then dispensed with.
    In a possible embodiment according to the invention it could be provided that the spindle is twisted and, at least in the axial direction relative to the spindle axis, is fixed immovably on the support structure. It is then particularly preferably provided that the spindle is fixed to the support structure, i.e. that all degrees of freedom of the spindle are locked in relation to the supporting structure.
    It could be provided that the spindle drive has a transmission gear for transmitting a rotary movement of the cable drum to a spindle nut of the spindle drive which engages in the spindle. This makes it possible to use a spindle with an external thread, which has a pitch that is less than the amount of the rope diameter of the at least one rope.
    In a possible embodiment variant, it is conceivable and possible that the or a spindle nut of the spindle drive engaging in the spindle can be twisted or fastened to the cable drum. In this embodiment it is therefore provided that the rotary movement of the cable drum is transmitted directly to the spindle nut.
    It could also be provided that the spindle nut engaging in the spindle is rotatably attached to the bearing frame of the cable drum.
    In another possible embodiment according to the invention it can be provided that the spindle drive has a spindle drive for rotating the spindle relative to the support structure. The rope drum can be moved entirely by means of the spindle drive, in particular when the spindle nut is fastened to the bearing frame. In

    However, it would also be conceivable for other embodiments of the patent office that, during operation, the cable drum rotation movement is superimposed on the rotation of the spindle of the spindle drive. Overall, however, it is always provided in the sense of the invention that the rope outlet point of the at least one rope is, at least essentially, stationary with respect to the support structure.
    The present invention also relates to a crane, in particular a gantry crane, for transporting at least one container or another load, the crane at least one trolley mounted on a crane girder of the crane, and a load suspension device for connection to the container or the other load, the load suspension device being able to be lifted and lowered on the trolley by means of ropes of the trolley, the trolley having at least one winch arrangement according to the invention for winding and / or unwinding the ropes of the trolley.
    It could be provided that a separate winch arrangement is provided for each rope of the trolley. It is particularly preferred if several ropes, e.g. four ropes, can be wound on a common rope drum. As already explained in connection with the possible embodiments of the cable winch arrangement, the grooves for receiving a respective cable can be arranged one behind the other in relation to the direction of the drum axis, i.e. spaced apart. Variants of rope drums with multi-start grooves are also conceivable and possible.
    Furthermore, the invention relates to a travel drive for displacing a transport unit which can be moved along travel rails, the travel drive comprising at least one cable winch arrangement according to the invention. The movable transport unit can be, for example, a crane. In another embodiment, the moveable transport unit can be a trolley which is movably mounted on a crane girder of a crane. In preferred embodiments, the cable winch arrangement is arranged on the transport unit. It is particularly advantageous if the drum axis of the cable drum is aligned parallel to a longitudinal extension of the travel rails.
    The invention also relates to a rake cleaning device for cleaning a rake, in particular a hydropower plant, the rake cleaning device having a cleaning device, in particular a cleaning rake or a gripping tool, for receiving flotsam pent up on the rake and a drive arrangement for actuating the cleaning device, wherein the drive arrangement has at least one cable winch arrangement according to the invention. The cable winch arrangement makes it possible to dispense with a complicated cable pulley arrangement for deflecting the cables in drive arrangements of the cleaning device.
    The drive arrangement of the rake cleaning device enables in particular the opening, closing or pivoting of the cleaning device for receiving or releasing flotsam. Furthermore, it could alternatively or additionally be provided that the screen cleaning device is supported on travel rails and has a travel drive having a winch arrangement according to the invention for moving the screen cleaning device along the travel rails.

    The cable winch arrangement 1 according to the invention shown in FIGS. 1 and 2 has a cable drum 2 for winding and / or unwinding a cable 30 and a storage frame 8 for the rotatable mounting of the cable drum 2 rotatable about a drum axis 3. The mounting of the cable drum 2 on the storage rack 8, for example with rolling bearings, is not shown separately in FIGS. 1 and 2. Such arrangements are, however, generally known in a variety of embodiments.
    The cable drum 2 has a drum jacket 4 and two drum flanges 7, which, in the axial direction with respect to the drum axis 3 on opposite sides, connect to the drum jacket 4. In the interior of the cable drum 2, a cavity 5 is formed, which, in the radial direction with respect to the drum axis 3, is delimited by the drum jacket 4. In the axial direction, based on the drum axis 3, the cavity 5 is delimited by the drum flanges 7.
    In the exemplary embodiment, the drum jacket 4 has a spiral groove 10 for receiving the rope 30. The spiral groove 10 is helical, i. H. in the manner of a helix extending along the drum axis 3. The groove 10 could also
    5/25
    AT 15 602 U2 2018-03-15 Austrian
    Patent office can be referred to as creasing. In the exemplary embodiment, the pitch of the spiral groove 10 corresponds to the rope diameter of the rope 30. In another embodiment variant, the pitch of the groove 10 could also have a pitch that is greater than the rope diameter of the rope 30, that is to say that the turns of the rope on the drum jacket 4 wound portion of the rope 30 are spaced apart. The drum jacket 4 of the cable drum 2 could also be designed without grooves in other design variants. That is, the outer surface of the drum shell 4 could, for example, be circular cylindrical, i.e. be smooth, educated.
    The cable winch arrangement 1 furthermore has a drum drive 9 for rotating the cable drum 2 about the drum axis 3 relative to the storage rack 8. As shown in the figures, the drum drive 9 can be a geared motor.
    The storage rack 8 is supported by support rollers 22 of the winch assembly 1 on a support structure 20. The support rollers 22 facilitate the relative movement of the storage rack 8 and thus the cable drum 2 with respect to the support structure 20. In another embodiment variant, instead of support rollers 22, skids or the like could also be used.
    The support structure 20 is shown only schematically in FIGS. 1 and 2 in order to illustrate the principle of the winch arrangement 1 according to the invention. In connection with the still to be explained application examples of the cable winch arrangement 1 according to the invention, possible design variants of the support structure 20 are discussed. In the exemplary embodiment shown in FIGS. 1 and 2, the support structure 20 has a rope passage 21 through which the rope 30 is threaded. However, a rope passage 21 is not mandatory.
    The cable winch arrangement 1 has a spindle drive 14 for displacing the cable drum 2 relative to the support structure 20. The spindle drive 14 comprises a spindle 16 extending along a spindle axis 15 and a spindle nut 17 which engages in the spindle 16. The spindle drive 17 connects the support structure 20 to the cable drum 2. The spindle axis 15 of the spindle drive 14 is arranged coaxially to the drum axis 3 of the cable drum 2.
    The spindle 16 is twisted in the first embodiment and fixed in the axial direction relative to the spindle axis 15 on the support structure 20. The spindle 16 is also immovably fixed to the support structure 20 in all directions orthogonal to the spindle axis 15.
    In the first exemplary embodiment, it is provided that the spindle nut 17 is attached to the cable drum 2 in a twisted test. A rotation of the cable drum 2 by means of the drum drive 9 therefore leads to a corresponding rotation of the spindle nut 17.
    An adjustment of the spindle nut 17 relative to the spindle 16 along the spindle axis 15 leads to a corresponding adjustment of the cable drum 2 along the drum axis 3 relative to the support structure 20. In the exemplary embodiment, the cable winch arrangement 1 has two end positions which relate the displacement path of the spindle nut 17 limit to spindle 16. Overall, the cable drum 2 can thus also be displaced relative to the support structure 20 between the first end position and the second end position of the cable winch arrangement 1.
    In the exemplary embodiment, the spindle drive 14 is designed as a trapezoidal screw drive. That is, the spindle nut 17 has a trapezoidal internal thread and the spindle 16 has a trapezoidal external thread, which interlock. Other variants of spindle drives are also conceivable and possible, as already mentioned at the beginning. For example, the spindle drive 14 could also be a flat-screw drive.
    In the first embodiment it is provided that the pitch of the spiral groove 10 corresponds to a pitch of the external thread of the spindle 16. One turn of the cable drum 2 by one turn, i.e. by 360 °, therefore leads to a relative displacement of the cable drum 2 with respect to the support structure 20, in a direction parallel to the drum axis 4, by the pitch of the external thread of the spindle 16. This can ensure that a cable outlet point 6 of the cable 30 on which the Rope 30 tangential to the rope drum
    6.25
    AT 15 602 U2 2018-03-15 Austrian
    Patent office runs and / or runs, based on the support structure 20, is at least essentially stationary. Since the pitch of the external thread of the spindle 16 in the first exemplary embodiment corresponds to the pitch of the spiral groove 10 of the drum jacket 4, it is thus necessarily ensured that the rope drain point 6 is always stationary with respect to the support structure 20.
    In Fig. 1, the cable drum 2 is shown in the first end position of the winch assembly 1, in which the cable 30, apart from a remaining length, which is wound on the cable drum 2, is unwound from the cable drum 2.
    2, the second end position is shown, in which the rope 30 is maximally wound on the rope drum 2. 1 and 2, it can be seen directly that the rope run-off point 6 is stationary in relation to the supporting structure 20, i.e. is immobile. This ensures that the cable 30 can run through the cable passage 21 regardless of the length of the section of the cable 30 wound on the cable drum 2.
    In the exemplary embodiment shown, it is provided that the spindle 16, in particular a section of the spindle 16 having the external thread, in the second end position, cf. Fig. 2, over at least 70% of the longitudinal extension of the spindle 16, in particular the longitudinal extension of the external thread of the spindle 16, extends into the cavity 5 of the cable drum 2.
    3 and 4, a second embodiment of a winch assembly 1 according to the invention is shown. The structure of the cable drum 2, the drum drive 9 and the support structure 20 corresponds to that of the first exemplary embodiment, so that the explanations for the second exemplary embodiment mainly refer to the differences from the first exemplary embodiment. Apart from the differences listed below, the explanations for the first embodiment also apply to the second embodiment.
    In the second embodiment it is provided that the external thread of the spindle 16 has a pitch that is smaller than the rope diameter of the rope 30. Accordingly, the pitch of the external thread of the spindle 16 is smaller than the pitch of the spiral groove 10 of the drum shell 4 Rope drum 2. In order to ensure that the rope run-off point 6 of the rope 30, at which the rope 30 runs tangentially from the rope drum 2 and / or runs onto the rope drum 2, is at least essentially stationary with respect to the support structure 20, the spindle drive 14 has Transmission gear 18 on. The transmission gear 18 transmits the rotary movement of the cable drum 2 to the spindle nut 17 of the spindle drive 14 which engages in the spindle 16. This means that the speed of the spindle nut 17 in the second exemplary embodiment is different from the rotational speed of the cable drum 2. The transmission gear 18 is configured such that a displacement dimension of the spindle nut 17 on the spindle 16, when the cable drum 2 is rotated by one revolution, corresponds to the pitch of the groove 10 of the cable drum 2 or the cable diameter of the cable 30.
    In the exemplary embodiment it is provided that the transmission gear 18 is attached to the bearing frame 8 in a twisted test and transmits the twisting movement of the cable drum 2 to the spindle nut 17 with the corresponding transmission ratio of the rotational speed.
    5 and 6, a third embodiment of a cable winch arrangement 1 according to the invention is shown. The construction of the cable drum 2, the drum drive 9 and the support structure 20 corresponds to that of the first exemplary embodiment, so that the explanations for the third exemplary embodiment mainly refer to the differences from the first exemplary embodiment. Apart from the differences listed below, the explanations for the first embodiment also apply to the third embodiment.
    In the third embodiment - similar to the second embodiment - it is provided that the external thread of the spindle 16 has a smaller pitch than the rope diameter of the rope 30. Accordingly, the pitch of the external thread of the spindle 16 is also smaller than the pitch of the spiral groove 10 of the drum jacket 4 of the cable drum 2. However, this is not mandatory, it could also be provided in an alternative embodiment that the pitch of the external thread of the spindle 16 is at least equal to that
    7.25
    AT 15 602 U2 2018-03-15 Austrian
    Patent Office
    Rope diameter of the rope 30 and / or at least the pitch of the spiral groove 10 corresponds.
    In the third exemplary embodiment, the spindle drive 14 has a spindle drive 19 for rotating the spindle 16 about the spindle axis 15 relative to the supporting structure 20. The spindle nut 17 is attached to the bearing frame 8 in a twisted test. A rotation of the spindle 16 by means of the spindle drive 19 causes the cable drum 2 to move relative to the support structure 20. The spindle drive 19 is controlled by means of control electronics (not shown in more detail) in such a way that the cable run-off point 6 of the cable 30, at which the cable 30 tangentially from the cable drum 2 runs up and / or runs off, is at least essentially stationary with respect to the support structure 20. In other words, the spindle drive 19 is controlled by the control electronics in such a way that the twisting movement of the cable drum 2 and the adjustment of the cable drum 2 by means of the drum drive 9 about the drum axis 3 in a direction parallel to the drum axis 3, i.e. coordinated with one another. are synchronous, with the cable outlet point 6 being at least substantially stationary with respect to the support structure 20. For this purpose, the control electronics could, for example, simultaneously control the drum drive 9 and the spindle drive 19 in order to bring about a synchronous control of the cable drum 2 and the spindle 16.
    In an alternative embodiment variant, it would be conceivable for the spindle nut 17 to be fixed in a twisted manner on the cable drum 2. The rotary movement of the cable drum 2 is then advantageously superimposed on that of the driven spindle 16. The control electronics can also be used to ensure that the cable outlet point 6 is at least essentially stationary with respect to the support structure 20.
    Exemplary applications of cable winch arrangement 1 according to the invention will now be discussed below. In principle, each of the three design variants shown in FIGS. 1 to 6 can be used in the applications explained below. For the sake of simplicity, the exemplary embodiments described below relate to special embodiment variants of the first embodiment of the cable winch arrangement 1 explained above. The modifications explained below, which relate, for example, to the number of cables that can be wound on a cable drum, are equally applicable to the mentioned further embodiments of cable winch arrangements according to the invention.
    7 to 14, a crane 40 designed as a gantry crane for transporting containers 41 in a container terminal is shown. The crane 40 is horizontally displaceable in relation to a direction orthogonal to the plane of the drawing, the crane 40 being supported on the crane rails 49 with trolleys 45 of the crane 40, cf. Fig. 7. In another embodiment of the crane 40, the trolleys 45 could also be air-tired and drive directly on the ground. The crane 40 also has a crane girder 42 which extends the area between the crane rails 49, i. H. a shelf for container 41, spanned. The crane girder 42 is supported on the trolleys 45 by means of uprights 46 of the crane 40. A trolley 43 is movably mounted on the crane girder 42, which can also be referred to as the main girder. The trolley 43 is supported by trolleys, not specified, on trolley rails 47 fastened on the crane girder 42. Furthermore, the crane 40 comprises a load suspension device 44 for connection to at least one container 41. The load suspension device 44 hangs on the trolley 43 with ropes 30 to 37 of the trolley 43 and can be relative to the trolley 43 by lengthening or shortening the free length of the ropes 30 to 37 are moved in the vertical direction. All of this is known per se in the prior art.
    The ropes 30 to 37 extending between the trolley 43 and the load suspension device 44 together form a rope shaft, also called a rope tower. 7 and 8, it can be seen that the geometry of the cable shaft, which is spanned by the cables 30 to 37, varies depending on the vertical position of the load-bearing device 44. In particular, the free length of the ropes 30 to 37 and the relative angles between the individual ropes 30 to 37 change, cf. also FIGS. 9 and 12.

In the exemplary embodiment, the cables 30 to 33 can be wound on a first cable drum 2 and the cables 34 to 37 on a second cable drum 2. The entirety of the ropes 30 to 33 could also be referred to as the first rope group and the entirety of the ropes 34 to 37 as the second rope group. As a result, the ropes 30 to 33, i.e. the first group of ropes, and ropes 34 to 37, i.e. the second group of cables, each synchronously wound onto the respective cable drum 2 or can be unwound from the respective cable drum 2.
    The respective cable winch arrangement 1 comprises a cable drum 2 rotatably mounted about a drum axis 3 for winding and unwinding the respective cable group, the cable winch arrangement 1 being designed analogously to the first exemplary embodiment according to FIGS. 1 and 2. That is, the cable winch arrangement 1 has a spindle drive 14 for displacing the cable drum 2 relative to the support structure 20 of the trolley 43. The spindle drive 14 comprises a spindle 16 extending along a spindle axis 15 and a spindle nut 14 which engages in the spindle 16. The spindle drive 14 connects the support structure 20 to the cable drum 2.
    The spindle axis 15, as shown only in FIG. 11, is arranged coaxially to the drum axis 3 of the cable drum 2. The spindle 16 is - similar to the exemplary embodiment shown in FIGS. 1, 2 - fixed in rotation on the support structure 20. The pitch of the external thread of the spindle 16 corresponds to the pitch of the spiral grooves 10 to 13, the latter being shown in FIG. 14 for one of the cable drums 2. The spindle drive 14 enables the cable drum 2 to be adjusted relative to the support structure 20 of the trolley 43. The bearing frame 8 of the cable winch arrangement 1 is supported by support rollers 22 on the support structure 20 of the trolley 43. Otherwise, with regard to the design of the cable winch arrangement 1, reference is made to the explanations for the first exemplary embodiment shown in FIGS.
    In the exemplary embodiment of the crane 40 shown, the drum jacket 4 of the respective cable drum 2 has four cable groove sections, each with a groove 10, 11, 12 and 13, spaced apart from one another in a direction parallel to the drum axis 3, cf. 14 in which the grooves 10-13 for one of the cable drums 2 are shown. That is, the ropes 30 to 33 or 34 to 37 of a respective rope group run at a distance from one another from the rope drum 2 or onto the rope drum 2, based on the longitudinal extent of the respective rope drum 2.
    The trolley 43 has rope pulleys 48 for deflecting a respective rope 30 to 37. The rope pulleys 48 have a circumferential rope groove in which the respective rope 30 to 37 is guided. The rope pulleys 48 have the purpose of deflecting the respective rope 30 to 37 to an anchoring point of a respective rope 30 to 37 on the load suspension device 44.
    Analogously to the first exemplary embodiment of the cable winch arrangement 1 illustrated in FIGS. 1 and 2, it is provided that a respective cable run-off point of the respective cable 30 to 37 wound on the cable drum 2, on which the respective cable 30 to 37 tangentially from the cable drum 2 runs up and / or runs off, is at least essentially stationary with respect to the support structure 20. That is, a rotation of the cable drum 2 leads to a corresponding displacement of the cable drum 2 relative to the support structure 20, the respective cable run-off point being essentially stationary with respect to the support structure 20. The respective rope drain point was not shown in FIGS. 7 to 14 for reasons of clarity.
    Between the respective rope run-off point and the respective rope pulley 48, the respective rope 30 to 37 advantageously runs in the tangential direction with respect to the drum axis 3. Since the cable run-off points are immobile, the number of cable pulleys 48 of the trolley 43 can be minimized, since the run-up angle of the respective cable 30 to 37 from the cable drum 2 to the respective cable pulley 48 remains constant. Conveniently, the respective rope pulleys 48 are aligned and positioned such that the respective rope 30 to 37 to be deflected is straight, i.e. without deviation from a rope groove level of the respective rope pulley 48, runs into the rope groove of the respective rope pulley 48 from the respective rope drain point.

    Patent Office [0079] An alternative exemplary embodiment of a cable winch arrangement 1 for a crane is shown in FIGS. 15 to 18. It is provided here that the drum axis 3, and thus also the spindle axis 15 of the spindle drive 14, are aligned vertically. In the exemplary embodiment shown, the ropes 30 to 33 run downwards in the vertical direction. The rope run-off point 6 was drawn in as an example for the rope 32. The rope outlet point 6 is stationary with respect to the support structure 20, which is only indicated schematically in FIGS. 15 and 17. To the same extent that the spindle nut 17 is displaced along the spindle 16, the cable drum 2 is also displaced relative to the support structure 20. 15, 17 one of the two end positions of the cable winch arrangement 1 is shown, a distance 23 between the drawn-in cable run-off point 6 of the cable 32 and a reference plane of the support structure 20 in the end positions, and also during the displacement of the cable drum 2 from one End position in the other end position is constant. The position of the cable pulleys 48 with respect to the supporting structure 20 is also stationary.
    16 and 18 are identical and show that the section of the respective cable 30 to 33 running from the cable drum 2 is tangential with respect to the drum axis 3.
    19 to 22 show a further application of a cable winch arrangement 1 according to the invention in a rake cleaning device 60. The rake cleaning device 60 is used to clean a rake 65 of a hydropower plant, not shown, for example in the region of a dam of a hydropower plant. The rake 65 is only indicated and, as is known, has a large number of through openings for water. Flotsam collects on the rake 65, which is separated from the water flowing through the passage openings. To receive flotsam dammed up on the rake 65, the rake cleaning device 60 has a cleaning device 61 which can have a cleaning rake or a gripping tool. The rake cleaning device 60 is supported by running gear 52 on rails 51.
    The screen cleaning device 60 has a travel drive 50 for displacing a movable transport unit 54 of the screen cleaning device 60. The transport unit 54 could also be referred to as the chassis of the screen cleaning device 60, cf. 20. In the exemplary embodiment it is provided that the travel drive 50 has a cable winch arrangement 1 according to the invention, which is arranged on the transport unit 54. Two cables 30, 31 can be wound or wound onto the cable drum 2 of the cable winch arrangement 1, one end of a respective cable 30, 31 being anchored to the cable drum 2. The ends of the cables 30, 31 remote from the cable drum 2 are anchored at, not shown, opposite anchoring points of the hydropower plant.
    In the exemplary embodiment, the travel drive 50 of the transport unit 54 has two rope pulleys 48 for deflecting the ropes 30, 31 running from the rope drum 2 in opposite directions parallel to the longitudinal extension of the travel tracks 51. The rope pulleys 48 are stationary with respect to the support structure 20.
    Rotation of the cable drum 2 by means of the drum drive 9 simultaneously leads to the winding of one of the ropes 30, 31 and to the unwinding of the other of the two ropes 30, 31. As a result, the transport unit 54 is moved along the rails 51.
    Deviating from the transport unit 54 of a rake cleaning device 60 shown in FIGS. 19 to 22, the transport unit 54 could also be a trolley, for example a crane, as shown in FIGS. 7, 8. With the travel drive 50 it would then be possible to change the positioning of the trolley along the crane girder of the crane. In another embodiment variant of the invention, the crane 40 itself could also be displaceable along crane rails or, in the case of tires, along the subsurface by means of such a drive mechanism, in which case at least one of the trolleys of the crane has a drive mechanism with a cable winch arrangement.
    23 to 26 show yet another application of a cable winch arrangement 1 according to the invention in a rake cleaning device 60. The rake cleaning10 / 25
    AT 15 602 U2 2018-03-15 Austrian
    Patent office device 60 has a cleaning device 61 designed as a gripping tool and a drive arrangement 62 for actuating cleaning device 61. The drive arrangement 62 comprises the cable winch arrangement 1.
    The cleaning device 61 can be displaced in the vertical direction along the rake 65, cf. 23 the travel directions 71 of the cleaning device 61 shown as a double arrow in FIG. 23. The cleaning device 61 has a plurality of gripping arms 68 and a comb 69, the gripping arms 68 being pivotable about a pivot axis 72 relative to the comb 69. 23, due to the side view, only one of the gripping arms 68 is shown. All gripper arms 68 are conveniently twisted together, i.e. the gripping arms 68 can be pivoted together about the pivot axis 72. FIG. 23 shows an open state of the cleaning device 61 for receiving or releasing flotsam in solid lines and a closed position of the cleaning device 61 for gripping and holding the flotsam in dashed lines. Such cleaning devices 61 are known per se.
    The drive arrangement 62 comprises one of the cable winch arrangements 1 already explained for winding and / or unwinding three cables 30-32, cf. 24. Furthermore, the drive arrangement 62 comprises two rope pulleys 63 for deflecting the ropes 30, 31 and a double rope pulley 64 for deflecting the rope 32 and a rope pulley 66 that can be displaced relative to the double rope pulley 64. The rope pulleys 63 and the double rope pulley 64 are relative to the supporting structure 20 stationary. The displaceable rope pulley 66 is stationary with respect to the support structure 20 with respect to a direction parallel to the drum axis 3. In the exemplary embodiment, the displaceable rope pulley 66 can be displaced in a plane orthogonal to the drum axis 3 relative to the double rope pulley 64, as is shown schematically in FIG. 23.
    The two end positions of the displaceable rope pulley 66, which is displaceable along a displacement path 67, are shown in solid or dashed lines.
    The respective free end of the ropes 30, 31 is anchored to the cleaning device 61. The rope 32 runs from the rope drum 2 into a first rope groove of the double rope pulley 64 and in the direction towards the rope pulley 66 from the first rope groove. The rope pulley 66 deflects the rope 32 into a second rope groove of the double rope pulley 64. The rope 32 is guided from the second rope groove of the double rope pulley 64 to the screen cleaning device 61. A deflection rope pulley 70 is arranged on the rake cleaning device 61, which deflects the rope 32 to an anchoring point on the gripping arms 68, cf. 23, 24.
    The rotation of the cable drum 2 of the cable winch arrangement 1 leads to a synchronous sequence of the cables 30, 31 and 32. the cleaning device 61 can be easily adjusted in the vertical direction without the cleaning device 61 skewing. The rope run-off points 6 of the ropes 30 to 32 shown in FIGS. 25, 26 are essentially stationary in the sense of the invention, based on the support structure 20. With regard to the design of the cable winch arrangement 1, reference is again made to the explanations relating to FIGS. 1 and 2.
    By moving the displaceable rope roller 66 along the displacement path 67 relative to the double rope roller 64, the free end of the rope 32 can be moved relative to the free ends of the ropes 30, 31. Since the rope 32 is anchored to the gripping arms 68, the relative movement of the displaceable rope pulley 66 to the double rope pulley 64 leads by appropriate extension or shortening of the free rope length of the rope 32 anchored to the gripping arms 68 to pivot the gripping arms 68 between the above-mentioned states, i.e. the open state and the closed state of the cleaning device 61, cf. Fig. 23.
    As already explained, the cleaning device 61 in the exemplary embodiment shown in FIGS. 22 to 26 can be displaced in the vertical direction along the rake 65. In another embodiment variant, the rake 65 could be inclined relative to a horizontal by 45 ° to 85 °, preferably by 60 ° to 80 °. The travel directions 71 of the Reini11 / 25
    AT 15 602 U2 2018-03-15 Austrian
    Patentamt supply device 61 are then advantageously aligned parallel to the orientation of the inclined rake 65.
    In a further embodiment variant, the rake cleaning device 60 shown in FIGS. 23-26 could also have a travel drive 50 with which the rake cleaning device 60 can be displaced along travel rails 51, as is the case with the rake cleaning device 60 according to FIGS. 22 is shown. That is, the rake cleaning device could then have two cable winch arrangements 1, one of the cable winch arrangements 1 serving as a travel drive 50 and a second cable winch arrangement 1 serving as a drive arrangement 62 for actuating the cleaning device 61.
