Definitions

  • the invention relates to a pivoting device for a work tool of a work machine, in particular an excavator or crane.
  • the pivoting device comprises a first pivoting section for attaching a work tool to the pivoting device and a second pivoting section pivotable about a pivot axis relative to the first pivoting section for attaching the pivoting device to a boom arm of the work machine.
  • Such a pivoting device is generally known and is typically used to pivot the work tool attached to the extension arm by means of the pivoting device.
  • the pivoting device is generally mounted on the extension arm in such a way that the pivot axis of the pivoting device is aligned approximately parallel to the longitudinal extension of the extension arm.
  • a different orientation of the pivot axis relative to the extension arm is also possible.
  • the swivel device can be used alone or in conjunction with a rotating device to rotate the work tool, particularly by 360°.
  • the rotation axis of the rotating device is preferably aligned perpendicular to the pivot axis of the swivel device.
  • the combination of the swivel device and the rotating device increases the number of degrees of freedom in which the work tool can be moved, thus enabling work in hard-to-reach places and/or around obstacles.
  • the swivel device For such demanding applications, it is desirable for the swivel device to have a particularly compact design and at the same time allow swiveling within the largest possible swivel range.
  • a pivoting device having the features of claim 1 and in particular by a drive which is spatially arranged between the first pivoting section and the second pivoting section and which is designed to pivot the first pivoting section relative to the second pivoting section about the pivot axis.
  • the invention is based on the idea of integrating a drive of a swivel device in the manner of a hub drive into the swivel device.
  • the swivel device like the hub drive, thereby has a particularly compact design.
  • the swivel device has a comparatively large swivel range, which is ultimately only limited by the structural conditions of the swivel device.
  • the swivel device according to the invention enables swiveling from a non-swivelled neutral position by 90° in opposite directions, resulting in a total swivel range of 180°. In principle, however, a larger swivel range of more than 180° is also possible depending on the structural properties of the swivel device.
  • the first pivoting section and the second pivoting section of the pivoting device each comprise a base plate.
  • the drive is thus located between the base plates of the two pivoting sections, which can be pivoted relative to each other.
  • the base plates enable a good connection of the pivoting device to the extension arm of the work device and to the work tool.
  • the base plates can be flat and each define a plane, with the intersection angle between the planes changing by pivoting the pivoting sections of the pivoting device. In the non-pivoted neutral position, the planes are aligned parallel to each other.
  • a quick-change unit can be arranged on the base plate of the first swivel section and/or on the base plate of the second swivel section.
  • the quick-change units are arranged on the side of the respective base plate facing away from the drive. This facilitates optional use of the swivel device.
  • the quick-change unit of the first pivoting section which serves for coupling to the work tool, is complementary to a quick-change unit provided on the work tool.
  • the quick-change unit of the first pivoting section can be the same as a quick-change unit typically provided on the extension arm for coupling to the work tool.
  • the quick-change unit of the first pivoting section can have claws designed to receive a quick-change frame provided on the work tool.
  • the quick-change unit of the second pivoting section used for coupling to the extension arm can be complementary to a quick-change unit formed on the extension arm.

  • the quick-change unit of the second pivoting section can comprise a quick-change frame designed to be received in claws provided for this purpose on the extension arm.
  • a rotating device with a rotary drive defining a rotation axis can also be provided on one of the base plates.
  • the rotating device is arranged on the side of the base plate facing away from the drive.
  • the rotational axis of the rotary drive which can also be referred to as a rotator, is aligned at least approximately perpendicular to the pivot axis of the pivoting device.
  • This allows the working tool to be pivoted not only about the pivot axis, but also about the rotational axis of the rotary drive, which is aligned at least approximately perpendicular to it. This enables a more versatile use of the working tool.
  • the drive may comprise a motor.
  • the motor comprises a rotor rotatable about a rotational axis, which provides the rotational movement necessary for pivoting the pivoting device.
  • the motor is bidirectionally operable, allowing pivoting in two opposite directions.
  • a particularly compact design of the swivel device is achieved when the rotor's rotational axis is aligned parallel to the swivel axis of the swivel device, especially when the rotational axis and the swivel axis are aligned coaxially with each other.
  • a compact design of the swivel device is also possible when the rotor's rotational axis is parallel to the swivel axis of the swivel device.
  • the motor and/or rotary drive of the rotating device can be hydraulically driven. This allows a hydraulic system already present for operating the boom and/or the work tool to be used to drive the motor or rotary drive.
  • the motor or rotary drive can, for example, be designed as a so-called “internally” actuated hydraulic radial piston motor, in which a stator is arranged essentially radially within the rotor.
  • a stator is arranged essentially radially within the rotor.
  • Such a motor is generally known and comprises several drive pistons displaceable by hydraulic fluid, each guided in radial bores provided for this purpose in the stator.
  • the radial bores are arranged in a star shape with respect to the rotational axis, so that the rotor is rotated by alternating, sequential displacement of the drive pistons.
  • radial piston motor with internal thrust another motor can also be used.
  • a hydraulic radial piston motor with external thrust can be used.
  • the drive pistons are guided in a stator arranged radially outward relative to the rotor.
  • the motor or rotary drive can also be designed as a hydraulic axial piston motor.
  • the drive pistons are not displaced radially, but rather parallel to the axis of rotation.
  • the motor or rotary drive can also be driven electrically, for example in the form of an electric motor.
  • the drive may comprise a gear which can be driven by the motor.
  • the pivoting device has a particularly compact design if the motor and the gearbox are arranged in series, as seen in the direction of the pivot axis.
  • the motor can be attached to the gearbox, for example, to a gearbox housing.
  • the motor can be mounted exclusively on the gearbox.
  • the motor is thus supported solely by the gearbox and not by any other component of the swivel device.
  • This design allows for an even simpler and more compact design of the swivel device.
  • the pivoting device can have a fastening device for fastening the pivoting device to the extension arm of the work machine, wherein the fastening device is designed such that the motor and/or the connections for driving the motor face the work machine when the pivoting device is fastened to the work machine.
  • the fastening device is designed such that the motor and/or the connections for driving the motor face the work machine when the pivoting device is fastened to the work machine.
  • the fastening device can, for example, be the quick-change unit mentioned above.
  • the fastening device can also be formed by means by which the swivel device can be attached directly to the boom arm of the work machine, for example, by a screw connection.
  • the transmission can comprise a first transmission part and a second transmission part rotatable about a transmission axis relative to the first transmission part, wherein the first transmission part is attached to the first pivoting section of the pivoting device and the second transmission part is attached to the second pivoting section of the pivoting device.
  • the transmission axis like the rotational axis of the rotor, can be aligned parallel, in particular coaxially or spaced parallel, to the pivoting axis of the pivoting device.
  • the first gear part is fastened to a first fastening section protruding from the base plate of the first pivoting section and/or the second gear part is fastened to a second fastening section protruding from the base plate of the second pivoting section.
  • additional sections can also protrude from the base plates, for example to provide additional support for the drive and/or to accommodate a pivot bearing.
  • the first fastening section can have a fastening surface which is aligned at least approximately at right angles to the base plate of the first pivoting section and to which the first gear part is fastened.
  • the second fastening section can have a fastening surface which is aligned at least approximately at right angles to the base plate of the second pivoting section and to which the second gear part is fastened.

  • the second fastening sleeve can comprise a fastening surface, as described above, oriented at least approximately perpendicular to the base plate of the second pivoting section, to which the second gear part is fastened.
  • the first fastening sleeve has, on its side facing away from its fastening surface, a beveled end face that is inclined from the first contact surface toward the fastening surface of the first fastening sleeve.
  • the first contact surface thus forms a long side of the first fastening sleeve.
  • the second fastening sleeve may have a beveled end face on its side facing away from its fastening surface, which is inclined from the second contact surface toward the fastening surface of the second fastening sleeve. Accordingly, the second contact surface forms a long side of the second fastening sleeve.
  • the beveled end faces of the mounting sleeves allow for material and weight savings compared to a non-beveled mounting sleeve.
  • the contact surfaces forming the long sides of the mounting sleeve enable secure attachment of the respective mounting sleeve to the corresponding base plate.
  • a compact design of the swivel device is achieved if the swivel axis of the swivel device and the longitudinal center axis of the first fastening sleeve are aligned at least approximately parallel, in particular coaxial, to one another.
  • the pivot axis of the pivoting device and the longitudinal center axis of the second fastening sleeve can be aligned at least approximately parallel, in particular coaxial, to one another.
  • the first fastening sleeve and the second fastening sleeve can have at least approximately identical basic shapes. This makes it possible to use identical base bodies for the respective fastening sleeves, which may then need to be adapted to the respective conditions of the first transmission part or the second transmission part and/or the engine.
  • the drive includes a brake.
  • the brake can be assigned either to the transmission or to the motor.
  • the brake can be assigned to both the transmission and the motor.
  • the brake is preferably designed such that it is active and braking when the motor is not driven. This eliminates the need for the motor to be active to maintain a desired swivel position. Rather, the swivel mechanism remains in the desired swivel position even when the motor is inactive.
