    Lifting device for collection containers.
    The present invention relates to a lifting device for lifting and / or emptying collecting containers, with a carrier body to which coupling means are arranged for coupling a lifting eye of the collecting container, wherein the coupling means have a, preferably bell-shaped, coupling piece which is mounted on the lifting eye. can be placed and comprise a movable locking piece to be connected thereto, which can be introduced into the lifting eye.
    For collection containers that are used for collecting recyclable materials such as glass, cardboard or the like, or that are also used as waste containers, a lifting eye is usually provided on the top side to which the container can be lifted up from its location, for example to empty it or to dispose of. A load hook of a lifting device is usually suspended in said lifting eye, by means of which the collecting container is lifted.
    In order to be able to empty the collection container, in certain container types, in addition to the above-mentioned lifting eyes, further coupling eyes are sometimes arranged which are connected to an opening mechanism for opening the container, so that firstly the lifting container is lifted up at the central lifting eye, and subsequently a exert tensile force on said further coupling eyes and thereby open, for example, bottom valves of the container. Further load hooks are regularly hung in the said additional coupling eyes for opening the container, which hooks are height-adjustable relative to the load hook for the lifting eye in order to lift and empty the container in the said order.
    Such lifting devices are used, for example, in collecting vehicles which drive to different container locations and transfer the collected goods to a storage space of the vehicle, in order to subsequently transfer the goods to a central collecting or recycling station. processing place. The said collecting vehicles here advantageously comprise a boom crane. The above-mentioned lifting device is attached to the boom head of this boom crane by means of an extension coupling. The attachment coupling comprises in the usual manner a rotary motor to rotate the lifting device about an upright axis and to be able to align it with respect to the collecting container.
    Depending on the embodiment of the collection containers, the space available at the said lifting eye can be very limited, in particular when the additional coupling eyes for emptying the collection container are arranged very close to the central lifting eye. With such a limited space around the lifting eye, it becomes more or less difficult to bring the coupling means of the lifting device into engagement with the lifting eye of the collecting container, because the locking piece collides with the adjacent eyes when sliding inwards into the lifting eye. , resp. with the other, place-obstructing parts. This problem does not only exist with collection containers, but of course also with other lifting loads whose lifting eyes have to be grasped under limited space conditions. To this extent, it has hitherto been possible with such collection containers or other lifting loads, the lifting eyes of which are arranged in a limited space, to hang the relevant load hooks into the eyes by hand, which is impractical in particular in the aforementioned work with collecting vehicles. is because the driver has to get out of here and have to hang the collection hooks by hand.
    Starting from this fact, it is an object of the present invention to provide an improved lifting device of the above-mentioned type which avoids the disadvantages of the prior art and advantageously further develops the latter. In particular, even with limited space, an automated gripping of the lifting eye must be made possible without requiring a larger number of energy connections for individual control actuators.
    According to the invention this object is achieved by a lifting device according to claim 1. Preferred embodiments of the invention are the subject of the subclaims.
    It is therefore proposed to effect the locking of the lifting device with the lifting eye of the lifting load by means of a suitable turning movement and turning the locking piece inwards into the lifting eye, respectively. to rotate the recess provided for this on the coupling piece inwards, so that less space is required on the side of the lifting eye for the locking movement of the locking piece, in particular a smaller distance to the lifting eye from adjacent eyes is required. Here, on the one hand, the carrier body is rotated relative to the coupling piece of the lifting device that can be placed on the lifting eye and, on the other hand, the adjusting movement of the locking piece is adjusted to the said turning movement. According to the invention, the coupling piece is pivotally connected about an upright coupling pivot axis to the carrier body of the lifting device and a control device is provided for controlling the locking movement of the locking piece, depending on the rotation of the carrier body relative to the coupling piece. This not only resolves the mentioned location problem, but also a simple implementation of the coupling process is achieved, because it is not necessary to control and control several parameters simultaneously. By turning the carrier body of the lifting device relative to the coupling piece placed on the lifting eye, the locking piece controlled by the control device is automatically brought into its locking position, without the driver having to coordinate the locking movement carried out relative to the carrier body separately with the rotational movement between carrier body and coupling piece. With a rotation of the carrier body relative to the coupling piece, a predetermined triggering of the locking movement carried out additionally to the rotation takes place.
    In a further development of the invention, the adjusting movement of the locking piece, in dependence on the rotation of the carrier body relative to the coupling piece, is so forced that the locking piece is always in a defined position corresponding to a respective position of the coupling piece relative to the carrier body, ie at the locking piece, it is predetermined in which position it must be for a respective turning position of the coupling piece relative to the carrier body. This may cause incorrect operation resp. erroneous functions are avoided, so that the operator can certainly assume that the coupling means are locked when the carrier piece is in a defined rotational position with respect to the coupling piece and therefore with respect to the collecting container. In principle, however, it would also be possible to dispense with such a forced control of the locking piece and, for example, to effect a targeted activation of the locking movement only if the carrier body is rotated relative to the coupling piece, for example in such a way that a spring-driven adjusting movement of the locking piece is switched on when a predetermined rotation of the carrier piece relative to the coupling piece is achieved, so that it would then remain open, respectively, during further rotation. against the spring drive to actually drive the locking piece into the locking position. However, preference is given to the aforementioned forced control which can avoid faulty functions with greater certainty.
    In order to avoid additional energy connections for the adjusting movement of the locking piece, it is provided in an advantageous further development of the invention that the adjusting movement of the locking piece is derived from the rotational movement of the coupling piece relative to the carrier body. In an advantageous further development of the invention, the locking piece and / or a locking set element connected thereto can be mechanically connected to the coupling piece, respectively. with the axis of rotation thereof, so that a rotation of the coupling piece relative to the carrier body also causes a corresponding adjustment movement of the locking piece relative to the coupling piece. By such a coupling device serving as a drive between the locking piece and the coupling piece, respectively. the pivot axis thereof, separate actuators driven by an external energy can be dispensed with in order to bring about a setting movement of the locking piece, so that a setting movement of the locking piece need not be provided for separately controllable energy connection such as, for example, a hydraulic connection for the adjusting movement of the locking piece.
    In particular, for operating the coupling means, a single energy connection and / or a single actuator may be sufficient, despite the different movements of the components of the coupling means, wherein in an advantageous further development of the invention in particular only a rotary mechanism for rotating the carrier body around an upright axis of rotation. In particular, it can be applied to the boom cranes of crane vehicles, resp. pivotal mechanism arranged on collecting vehicles on the boom head of the hoisting crane is the only control drive for operating the coupling means and locking the lifting eye, said pivoting mechanism being, for example, the rotary motor intended for coupling the lifting device suspended in the forward and again moving coupling gear, by means of which a lower part of the coupling gear is rotated relative to the upper part of the coupling gear hingedly connected to the boom.
    In a further development of the invention, the coupling piece and / or the locking piece can be mounted on the carrier body without drive, i.e. without its own control actuator which is actuated by an external energy, in particular movable. Via the above-mentioned rotation mechanism for the carrier body, the carrier body is rotated about an upright axis, whereby a relative rotation between carrier body and coupling piece can be effected when said coupling piece is placed on the lifting eye. From this aforementioned relative movement between coupling piece and carrier body, the adjusting movement of the locking piece is derived from the said rotation via the above-mentioned mechanical connection between locking piece and coupling piece. As a result, the lifting device for locking the lifting eye comes out with only one energy connection. This is particularly advantageous when using the lifting device with the aforementioned collecting vehicles which have only two energy connections available in the usual manner at the head of the boom crane, so that the second energy connection can be used to operate the emptying device of the crane. collection container.
    However, if a sufficient number of energy connections are available that can be controlled separately, an alternative further development of the invention may also be provided with a separate control actuator for effecting an adjustment movement of the locking piece, for example in the form of a pressure medium cylinder, a spindle drive or the like which, depending on the rotation of the coupling piece relative to the carrier body, is then controlled by the above-mentioned control device to coordinate the adjusting movement of the locking piece with the rotation of the coupling piece relative to the carrier body.
    In order to also achieve the desired relative rotation between coupling piece and carrier body when the carrier body is rotated about an upright axis, for example by means of the above-mentioned rotary motor of the coupling tool on the boom head, i.e. to prevent the coupling piece from simply rotating, the coupling piece can in an advantageous further development of the invention are embodied such that, when placed on the lifting eye by its shape, it is secured against rotation thereto. In particular, the coupling piece, which is advantageously bell-shaped or yoke-shaped, may have a downwardly open recess for receiving an eye, which recess is adapted so far in shape to the lifting eye of the collecting container that the coupling piece is relative to the lifting eye in the condition placed thereon it is non-rotatable or can only be rotated to a limited extent. As a result, it is only necessary to place the lifting device with the coupling piece from above on the lifting eye, optionally after said coupling piece has been aligned with the lifting eye by turning the entire lifting device about an upright axis, and subsequently in a further step the carrier body with which the coupling piece is hinged and rotatably connected, so as to bring the coupling piece in its locking position in connection with the derived adjusting movement of the locking piece.
    In a further development of the invention, said coupling piece comprises a transverse recess for the locking piece into which said locking piece can be brought in, said transverse recess being advantageously arranged and aligned such that the locking piece, in the introduced position, transversely said eye-receiving recess extends and / or at least partially closes said eye-receiving device downwards, so that the coupling piece can no longer be lifted upwards by the lifting eye. In the said locking position, the locking piece extends through the lifting eye and / or engages on the underside of an upper part of the lifting eye, while the coupling piece sits on said lifting eye and engages it laterally, respectively. this encloses a bell or yoke.
    In order to be able to insert into the lifting eye even with a particularly limited space, the locking piece is not only movable relative to the coupling piece, but also movable relative to the carrier piece, wherein in principle the movability of the locking piece relative to the carrier piece can have different movement axes and / or tracks. In an advantageous further development of the invention, the locking piece can be rotatably and / or pivotably mounted to allow insertion of the locking piece into the lifting eye by means of superimposed pivotal and / or pivotal movements about two separate pivot and / or pivot axes. In particular, the rotation of the coupling piece relative to the carrier body can be superimposed on an additional pivoting movement of the locking piece relative to the carrier piece, whereby the locking piece can be inserted into said lifting eye even with very small gap dimensions of the lifting eye.
    In a further development of the invention, the locking piece is advantageously pivotally mounted about an upright pivot axis that is spaced apart from the coupling pivot axis of the coupling piece, so that when the locking piece is inserted two pivots which are parallel, upright and spaced apart from one another running turning and pivoting movements can be superimposed.
    In particular, said locking piece can be connected to the carrier body by means of a locking carrier arm, which is preferably bent at right angles and / or projecting from the carrier body and which is hinged and pivotally connected to the carrier body. Said locking bearing arm can, if desired, be designed to be movable once again on its own, for instance having two pivotable parts of a locking rotating arm which are preferably pivotable relative to each other about an upright axis of rotation, so that a three-axis pivoting movement for inserting the locking bolt would be effected could be. In the sense of a simple embodiment and a simple derivation of the pivoting movement from the rotation of the coupling piece, the said locking bearing arm can however also be rigid per se and can only be moved with respect to the carrier body on which the coupling piece is mounted, in particular pivotably mounted to be.
    In order to slide the locking piece inwardly and outwardly, little space is required, in an advantageous further development of the invention, the locking pivot is arranged and aligned such that the locking piece is in the unlocked position in the preferably immediate vicinity of the locking piece. coupling piece extends on the outside of the coupling piece, in particular is positioned along a wide side of said coupling piece, so that the coupling means in the unlocked position of the locking piece as a whole have a very narrow contour, the laterally protruding position of the locking piece until the coupling piece is clearly smaller than the length of the locking piece and / or the access path from the locking piece to the lifting eye.
    In a further development of the invention, said locking pivot axis about which the locking piece is rotatable relative to the carrier piece can be aligned parallel to the coupling pivot axis of the coupling piece and form a distance in one direction to the coupling pivot axis which, when the locking piece is locked in the locked position and / or the carrier body is in a rotational position relative to the coupling piece corresponding to the locked position, runs transversely to the eye eye position and / or runs transversely to the transverse recess of the coupling piece into which the locking piece is slid can become. In other words, the locking rotary axis is viewed in the direction parallel to the axis of the lifting eye by the axis of rotation of the coupling piece to the right or to the left when the lifting body of the lifting device is in the said locking position. The axis of the lifting eye is understood to mean the axis of the eye running centrally through the opening of the lifting eye.
    Depending on the intended purpose of the lifting device, i.e. depending on how the collecting container to be accommodated is designed, it may have further coupling pieces and / or adjusting members. In particular, the lifting device can comprise at least one further coupling piece which, in relation to the coupling means that can be coupled to the lifting eye of the collecting container, is height adjustable and / or mounted on said carrier body. In particular, at least one further coupling element can be arranged, with the aid of which an emptying element can be grasped which, for example in the form of a lifting eye which is further arranged on the top side of the collecting container, can be movably formed on the collecting container. In a further development of the invention, the lifting device can comprise two further coupling parts which can be arranged on opposite sides of the coupling piece which can be brought into engagement with the lifting eye of the collecting container, on the carrier body. If the lifting eye is coupled to the lifting device and if the collecting container is possibly raised, the said further coupling parts of the lifting device are raised and / or moved in the desired direction relative to the coupling piece coupled to the lifting eye in order to move the emptying mechanism of the collecting container into the desired direction. to operate.
    In a further development of the invention, the lifting device for operating the further coupling parts comprises a control actuator that can be operated by energy coming from outside.
    The above-mentioned carrier body can for instance be a carrier plate to which said coupling pieces and parts and the locking piece are hingedly connected for locking the lifting eye.
    The invention is explained in more detail below with reference to a preferred exemplary embodiment and associated drawings. In the drawing: Fig. 1 shows a schematic, perspective total view of the lifting device for lifting and emptying a collection container according to an advantageous embodiment of the invention, wherein on the top of the lifting device a quick coupler for the reciprocating moving suspension of the lifting device to a crane boom is shown and on the underside of the device coupling means for coupling the lifting eye of a collecting container (not shown), and two further coupling pieces on the right and left thereof are shown for coupling the tie rods for emptying the collecting container, fig. 2 shows a partial, perspective view of the coupling means for coupling the lifting eye of the collecting container, wherein the coupling means and the lifting eye are shown in a position not yet engaged at the start of the coupling process. FIG. 3 is a partial perspective view of the coupling means for coupling the lifting eye of the collecting container, the coupling means being shown in a position in which the coupling piece is already placed on the lifting eye, but the rotation of the carrier body relative to the coupling piece is still not initiated.
    Fig. 4 is a partial perspective view of the coupling means for coupling the lifting eye of the collection container, wherein the carrier body is already rotated a lot further compared to Fig. 3 with respect to the lifting eye of the collection container, respectively. the connecting piece connected thereto, through which the locking piece has already been moved inwards a bit further into the transverse recess of the connecting piece, and Fig. 5 shows a partial perspective view of the coupling means for coupling the lifting eye, wherein the locked end position is shown, in which the carrier body is fully rotated with respect to the coupling piece and the locking piece is thereby fully moved inwards in the lifting eye.
    The lifting device 1 shown in Fig. 1 comprises an apparatus body 25 which at its top comprises a coupling 5 for coupling the lifting device 1 to a crane boom 3 only indicated in the drawing. The said coupling 5 is in a manner customary in itself hanging and moving again on the boom head piece 4 of the crane boom 3 and comprises a rotary motor 6 with which said coupling 5 can be turned on itself about an upright axis, ie the lower part of the coupling device to which the device body 25 of the lifting device 1 is attached mounted, can be pivoted about an upright axis relative to the upper part of the coupling device which is suspended back and forth on the crane boom 3, whereby the lifting device 1 can be pivoted in its entirety about an upright axis.
    On the underside of the device body 25, the lifting device 1 comprises on the one hand coupling means 8 for being able to couple a lifting eye 9 of a collecting container 2, and on the other hand further coupling means 23 for being able to grip the emptying eyes 24 further arranged on the collecting container 2. As Fig. 1 and also Figs. 2-5 show, the said emptying eyes 24 are arranged to the right and left of the central lifting eye 9 of the collecting container 2, so that the lifting eye 9 is arranged in a limited space and there is only a small distance to the adjacent emptying eyes 24. In accordance with the arrangement of said lifting and emptying eyes 9, resp. 24, said coupling parts 23 of the lifting device 1 are also arranged to the right and left of the coupling means for the lifting eye 9. In order to pull the emptying eyes 24 away from the collecting container in an upward direction after lifting the collecting container 2 in order to be able to open bottom valves of the collecting container 2 via connecting rods 26, said coupling parts 23 are connected to the device body 25 relative to the coupling means 8 height adjustable. To this end, corresponding control actuators, for example in the form of hydraulic cylinders, are arranged in the interior of the device body 25 in order to be able to adjust the height of the coupling parts 23 relative to the central coupling means 8 for the lifting eye 9.
    The coupling means 8, as well as the coupling parts 23 on the underside of the device body 25 are mounted on a plate-shaped carrier body 7 which can form a part of the device body 25. As Figures 2 to 5 show in more detail, the carrier body 7 can essentially consist of a lifting plate, but other embodiments are also possible.
    In the embodiment shown, the above-mentioned coupling means 9 for coupling the central lifting eye 9 of the collecting container 2 comprise an approximately bell-shaped coupling piece 12 which has a downwardly open recess 20 for receiving an eye, with which the coupling piece 12 over the lifting eye 9 can be inserted, so that the lifting eye 9 is at least partially enclosed by the body of the coupling piece 12 and in particular an upper part of the eye bracket 27 is received in the coupling piece 12.
    Said recess 20 for receiving the eye is advantageously at least slightly adapted in shape to the lifting eye 9, so that the coupling piece 12 can be placed accurately fittingly on the lifting eye 9 and cannot be rotated with respect to the raised eye lifting eye 9.
    Said coupling piece 12 is rotatably mounted on said carrier body 7 about a vertical coupling pivot axis 14, so that the coupling piece 12 can be rotated relative to the apparatus body 25 of the lifting device 1, as will be explained in more detail below. In the embodiment shown, the coupling piece 12 is in this case non-rotatably connected to the said coupling swivel shaft 14 itself, so that when the coupling piece 12 rotates, the said coupling swivel shaft 14 also rotates.
    Furthermore, the above-mentioned coupling means 8 comprise a locking piece 13 which cooperates with the coupling piece 12 and which can lock the lifting eye 9 to the coupling piece 12. To this end, the coupling piece 12 comprises a transverse locking recess 21 which intersects the above-described eye-receiving recess 20 and is arranged and aligned such that when it is pushed into said locking recess, the locking piece 13 extends through the lifting eye 9 as shown in FIG. 5.
    In the embodiment shown, the locking piece 13 is an - generally speaking - elongated, substantially block-shaped body arranged at a distance from the underside of the carrier body 7 and both with respect to the coupling piece 12 and with respect to the carrier body 7 can be moved.
    As Figures 2-5 show, the locking piece 13 is attached to a locking bearing arm 22 which protrudes protruding from the bottom of the carrier body 7 and in the shown embodiment is bent at right angles so that it also from the bottom of the carrier body 7 engaging the underside of the carrier body 7 protruding coupling piece 12.
    Said locking bearing arm 22 is rotatable or rotatable about a vertical locking rotation shaft 15, respectively. pivotably connected pivotally to the support body 7. In the embodiment shown, the locking pivot axis 15 and the coupling pivot axis 14 extend parallel to each other at a predetermined mutual distance relative to each other, which is advantageously not too great for the necessity of too great a avoid swiveling path for the locking piece. In terms of size, the distance from the locking pivot 15 to the coupling pivot 14 is approximately half the length of the locking piece 13, which may also vary depending on the circumstances and, for example, an axis distance of 50% to 300% of the length of the locking piece 13 and, depending on the shape of the coupling piece and / or the locking piece, other distance ratios can also be advantageous. Alternatively or additionally, the distance from the locking piece 13 to the said locking pivot axis 15, which is determined by the protruding, perpendicularly curved shape of the locking bearing arm 22, is not too great, in order not to have an excessively large pivot path for the locking piece 13 and therefore not all require too much space for the pivoting movement. In the embodiment shown, the radius, ie the distance from the locking piece 13 to the locking pivot axis 15 - generally speaking - is approximately the axis distance from the locking pivot axis 15 to the coupling pivot axis 14, here too depending on the positioning of the locking pivot axis 15 and the embodiment of the coupling piece 12 other distances from the locking piece 13 to the locking pivot 15 can advantageously be in the range of 50% to 300% of the distance from the coupling pivot 14 to the locking pivot 15, wherein, depending on the nature of the coupling 12 and / or the distance from the lifting eye 9 to the emptying eyes 24 other distances can be chosen.
    As Fig. 2 shows, the movability of the locking piece 13 and / or the kinematics of the suspension of the locking piece 13 is such that the locking piece 13 in its unlocked starting position according to Fig. 2 extends outside the coupling piece 12 in its vicinity. wherein the locking piece 13 advantageously extends with its longitudinal axis parallel along the outside of the coupling piece 12, in the direction from which the locking recess 21 is opened, ie along the outside, from which the locking piece 13 can be inserted into the locking recess 21 . As Fig. 2 shows, the locking piece 13 can advantageously extend with its longitudinal axis in principle perpendicular to the longitudinal axis of the locking recess 21.
    The said locking piece 13 is now removed from the holder. To bring the unlocked position shown in Fig. 2 into its locked position, into which the locking piece 13 is slid and extends through the lifting eye 9, on the one hand the carrier body 7 is rotated relative to the coupling piece 12 sitting on the lifting eye 9 and on the other hand the locking bearing arm 22 is pivoted with respect to the carrier body 7.
    Around the first mentioned turning or resp. In order to achieve a pivotal movement, i.e. to rotate the carrier body 7 relative to the coupling piece 12, the rotary motor 6 of the coupling gear is actuated, whereby the entire apparatus body 25 of the lifting device 1 is rotated about the upright axis. The coupling piece 12 was previously placed on the lifting eye 9, as shown in Fig. 3, so that the coupling piece 12 cannot rotate with the device body 25.
    The superimposed rotation and pivoting movement of the locking piece 13 is derived from the rotation of the carrier body 7 relative to the coupling piece 12. As figures 2-5 show, a mechanical connection 19 is provided between the locking piece 13 and the coupling pivot shaft 14 which drive means 18 for effecting the adjusting movement of the locking piece 13. In the embodiment shown, said mechanical connection 19 comprises a transmission stage 28 between the coupling pivot axis 14 and the locking pivot axis 15, to which the locking carrier arm 22 is connected. Said transfer stage 28 can be designed differently depending on the required acceleration or deceleration, whereby a non-linear or non-linear drive may also be provided. a non-proportional acceleration / deceleration can be realized, for example such that an initial part of the rotation of the clutch rotation shaft 14 is converted into a smaller rotation of the locking rotation shaft 15, while a later part of the rotation of the clutch rotation shaft 14 is converted into a stronger rotation of the locking rotary shaft 15. In the sense of a simple embodiment of the transmission stage 28, however, a proportional acceleration / deceleration can be realized by, for example, a pair of gears 29 and 30, one of which is non-rotatably connected to the coupling rotary shaft 14 and one to the locking pivot shaft 15. In the embodiment shown, pinions combining with each other are arranged as gears 29 and 30, while other transmission elements can however also realize said transmission stage 28.
    After the coupling piece 12 has been placed in the unlocked starting position on the lifting eye 9, as shown in Fig. 3, the entire device body 25 of the lifting device 1 is only rotated via the rotary motor 6 of the coupling gear. As a result of the relative rotation of the coupling piece 12 relative to the carrier body 7 resulting from this, the locking bearing arm 22 is simultaneously rotated via the said mechanical connection 19 and thereby the locking piece 13 is rotated relative to the carrier body 7, the pivotal path of the locking piece 13 being of course of such that the locking piece 13 is moved inwards into the locking recess of the coupling piece 12, as shown in figures 4 and 5.
    Through the transfer stage 28, the locking piece 13 carries out a greater angle of rotation than the device body 25 and the carrier body 7. As a result, the locking piece 13 is quickly brought in with a relatively small swinging movement into the locking recess 21 of the coupling piece, whereby the lifting eye 9 into the coupling piece 12 is fixed and can be raised. Due to the additional pivoting movement of the locking piece 13 relative to the carrier body 7, the lifting eye 9 can also be accommodated at the most limited space. As a result of the derivation of the superimposed locking swing movement from a rotation of the carrier body 7 relative to the lifting eye 9 to be received, there is no need to provide a separate actuator for the locking bearing arm 22, for which purpose a separate, individually controllable energy connection to the boom head piece 4 of the crane boom 3 would have been necessary.
