Definitions

  • Cable drum carrier for the rotatable mounting of a cable drum
  • the invention relates to a cable drum support for the rotatable mounting of a cable drum, as is used in particular on construction sites or developments.
  • Such cable drums can have a diameter of several meters and weigh several tons.
  • the weight is also determined by the cable wound up on the cable drum. If the cable is, for example, a power line with a metal core and electrical insulation, the weight will be higher than with a cable that is designed as a media hose for liquid or gaseous media, for example.
  • cable drum carriers are known on which the cable drums can be securely rotatably mounted.
  • cable drum trolleys that have a chassis on which the cable drum is held are usually used for this purpose.
  • a working machine then has to pull or tow the cable drum carriage behind it in order to unwind the cable wound onto the cable drum. Due to the high weight of such a cable trolley, manual displacement of the trolley or pivoting of the trolley about a vertical axis is often difficult or impossible.
  • cable drum carriers which can be fastened to a pivotable working arm of the excavator. These have an elongate mandrel or bearing bolt, which extends axially further than the cable drum to be accommodated, which can be pushed onto the mandrel.
  • the construction machine can be used to switch between different cable drums relatively quickly. Due to the mechanical design, however, particularly high leverage forces act on the bearing mandrel, making it difficult to operate the cable drum carrier. In addition, this variant requires that there is plenty of free space for the construction machine to maneuver the cable drum.
  • the invention is therefore based on the object of creating an improved cable drum carrier that enables simple operation, in particular by existing construction machines or working machines, in which cable drums can be easily picked up and released and their safe and rotatable storage guaranteed.
  • the object on which the invention is based is achieved by a cable drum carrier having the features of claim 1 .
  • This has the advantage that a cable drum can be gripped axially from two sides and pivoted. There is no continuous bearing dome. Instead, bearing bolts can be inserted into front openings of the cable drum from two sides, as a result of which the cable drum is advantageously held in balance on the cable drum carrier. This enables the bearing bolts to be easily inserted and removed from the cable drum.
  • the cable drum carrier according to the invention ensures that the received cable drum can be actively rotated by the cable drum carrier in order to facilitate unrolling or rolling up.
  • the cable drum support according to the invention is characterized in that it has a cross member on which two holding arms aligned parallel to one another are arranged, with each holding arm having a laterally protruding and rotatably mounted bearing pin at a free end, the bearing pins being aligned with one another on the holding arms are arranged facing and aligned parallel to the cross member. At least one of the holding arms is slidably mounted along the cross member.
  • the fact that the bearing pins are aligned and aligned parallel to the cross member means that when at least one of the holding arms is displaced along the cross member, the alignment of the bearing pins is maintained.
  • the cable drum carrier has at least one controllable actuator which is designed to displace at least one of the holding arms and/or to apply a torque to at least one of the bearing bolts to rotate about its longitudinal central axis.
  • the actuator thus enables automated displacement of the holding arms and thus of the spacing of the bearing bolts from one another. If the actuator is designed to apply a torque to the at least one bearing pin, it is possible to drive an accommodated cable drum.
  • An actuator is preferably provided both for displacing the holding arms and for driving the bearing pin, or there is an actuator which is designed both for displacing the at least one retaining arm and for driving the at least one bearing pin.
  • the cable drum carrier has a first actuator, which is arranged on the cross member and is operatively connected to at least one of the holding arms, in particular to both holding arms, for its displacement. The actuator is thus located on the cross member and is used to move at least one of the holding arms along the cross member. The actuator thus represents an integral part of the cable drum carrier.
  • both holding arms can be displaced in opposite directions on the cross member by a gear mechanism connected to the first actuator.
  • the transmission ensures that the holding arms are always displaced in opposite directions along the cross member, so that, for example, by driving only one of the holding arms, the other of the holding arms is also moved, but in opposite directions. This ensures that the holding arms on the cross member are pushed onto one another or pushed away from one another evenly. This has the advantage, in particular, that the balance of the cable drum carrier is not impaired by a displacement of the holding arms, as a result of which safe operation of the cable drum carrier is ensured.
  • the cable drum carrier preferably has a second actuator which is operatively connected to the at least one bearing bolt in order to drive it to rotate.
  • a first actuator for the holding arms and a second actuator for the bearing pin. This makes it possible to drive the holding arms independently of the bearing bolt, which in particular reliably prevents incorrect operation.
  • the first actuator and/or the second actuator are each designed as a hydraulic actuator.
  • the two actuators can thus be driven hydraulically in order to move the holding arm or arms and/or to drive the bearing pin or the bearing pins to rotate.
  • the design as a hydraulic actuator results in the advantage that the cable drum carrier can be easily integrated into existing construction machine systems that have a hydraulic supply circuit, for example to operate a working arm of the construction machine or, for example, a tool that can be attached to the working arm, such as a bucket. chisel or the like.
  • existing drive systems are used, which means that the cable drum carrier can be integrated into existing construction machine systems without much additional effort.
  • at least one of the actuators as electromotive actuator formed. This also enables precise control of the holding arms and/or the bearing pin.
  • the first actuator is particularly preferably designed as a hydraulic cylinder.
  • the hydraulic cylinder has a working cylinder with a piston mounted displaceably therein.
  • the piston is preferably firmly connected to one of the holding arms by a piston rod, and the cylinder is connected to the cross member. If a hydraulic pressure is now generated in the working cylinder, the piston is displaced by the hydraulic pressure within the working cylinder and the piston rod or the holding arm is thus also displaced along the cross member.
  • the hydraulic cylinder works in two working directions, so that by applying pressure to one or the other side of the piston within the working cylinder, the piston can be displaced in one direction or the other in order to push the bearing bolts or the retaining arms together or apart guarantee.
  • the working cylinder is connected to one of the holding arms and the piston is connected to the cross member.
  • a hydraulic cylinder, as described above, is particularly preferably present for each of the holding arms, so that both holding arms can be displaced hydraulically. As a result, there is no need for an additional mechanical gear mechanism, which acts between the holding arms and causes the opposite displacement.
  • the second actuator is designed as a hydraulic motor. This is driven hydraulically and is operatively connected to the at least one bearing pin, directly or through a gear, in order to convert the hydraulic force into a torque acting on the bearing pin.
  • a corresponding second actuator is preferably assigned to each of the bearing bolts, so that the bearing bolts can both be driven hydraulically.
  • the cable drum carrier has a first hydraulic system, which has a first hydraulic circuit with the first actuator and a second hydraulic circuit with the second actuator, and at least one switching valve, through which either the first hydraulic circuit or the second hydraulic circuit can be connected to a hydraulic connection for a hydraulic supply system can be connected.
  • actuating the at least one switching valve it is thus possible to set which of the hydraulic circuits of the first hydraulic system is active and which is blocked. This ensures that only one of the two hydraulic circuits of the first hydraulic system can be used. This ensures, for example, that in a case in which the bearing pin with a torque is applied, not simultaneously one of the support arms can be driven to increase the distance to the other support arm. This increases the operational reliability of the cable drum carrier.
  • the hydraulic connection is designed in particular so that it can be connected to a mating connection of the hydraulic supply system. The hydraulic connection can thus be or be adapted to different hydraulic supply systems.
  • the hydraulic connection is preferably arranged between the arms, in particular centrally on the cross member—seen in the longitudinal extent of the cross member—so that a centralized connection of the first hydraulic system to the hydraulic supply system is made possible.
  • the cross member has a fastening point for fastening the cable drum carrier to the construction machine in the area of the hydraulic connection, ie in particular in the middle between the arms, so that the fastening and the hydraulic connection are close to one another.
  • the cable drum carrier particularly preferably has an actuatable coupling for the detachable mechanical attachment of the cable drum carrier to a working machine, in particular to an operating arm of the working machine.
  • the coupling is arranged on the cross member of the cable drum carrier, preferably centrally between the holding arms, or centrally on the cross member as viewed in the longitudinal extension of the cross member.
  • a simple mechanical connection to the working machine can be established or released by the coupling. This ensures, in particular, that the cable drum carrier can be picked up easily by a working machine and that it can be put down easily.
  • the coupling is, for example, a quick coupler or a quick coupling, as is already used in existing construction machine systems.
  • the cable drum carrier particularly preferably has a second hydraulic system which has a hydraulically drivable third actuator, the actuatable clutch being rotatably mounted on the cross member, and the third actuator being designed to rotate the clutch relative to the cross member when it is actuated.
  • the second hydraulic system particularly preferably has a second hydraulic connection which is assigned to the clutch.
  • the second hydraulic connection for the second hydraulic system is also arranged close to the coupling and thus to the attachment point on the construction machine, which ensures that it is easy to overcome when installing the cable drum carrier on the construction machine.
  • the coupling is preferably designed to also produce at least one hydraulic connection between the hydraulic supply system and the first and/or the second hydraulic system when the cable drum carrier is mechanically fastened.
  • the coupling is therefore not used for the mechanical connection of the cable drum carrier to a construction machine, but also for the hydraulic connection.
  • the hydraulic connection is automatically established or released by actuating the clutch. This ensures easy connection of the entire cable drum carrier to a construction machine, both mechanically and hydraulically.
  • the first hydraulic system has two switching valves, which only connect the first hydraulic circuit to the hydraulic connection when both switching valves are in a first of two switching positions. If one of the two switching valves is shifted to a second of the two switching positions, the first hydraulic circuit can no longer be used. This ensures that the holding arms can only be moved toward or away from one another when both switching valves are in the first switching position. As a result, incorrect operation of the cable drum carrier can be reliably prevented.
  • the switching valves are preferably designed and connected to the hydraulic circuits in such a way that the second hydraulic circuit can only be used when both switching valves are in the second of the two switching positions. A torque can therefore only be applied to the bearing bolt when both switching valves have been moved into the second switching position.
  • the two switching valves are preferably manual switching valves, with one of the manual switching valves being arranged on each of the holding arms.
  • the switching valves are arranged or can be arranged far away from one another on the cable drum carrier, so that accidental operation of both switching valves is reliably prevented.
  • the operational reliability of the cable drum carrier is thus further increased.
  • the two switching valves are each located on one of the cable drums or on the opposite holding arm facing away from the outside of the respective arm, so they are easily accessible for a user.
  • At least one throttle valve is arranged in the second hydraulic circuit.
  • the hydraulic pressure or hydraulic flow provided by the hydraulic supply system can be regulated or influenced by the throttle valve in order, for example, to adjust the torque acting on the bearing bolt and thus the rotational speed achieved.
  • the throttle valve is designed as a manually operable throttle valve, so that a user can manually set or influence the rotational speed of the bearing bolt by actuating the throttle valve.
  • two throttle valves are arranged in the second hydraulic circuit, in particular one on each of the holding arms, in order to simplify the setting of the speed or torque for the user, since he can now influence the hydraulic flow for the second hydraulic actuator from both sides of the cable drum carrier.
  • an axial protective disk for a cable drum is arranged in a rotationally fixed manner on the respective bearing bolt.
  • the axial support disk ensures that the cable drum can be clamped axially between the two axial support disks and, in particular, that its end face cannot hit one of the holding arms directly and thus lead to wear or damage.
  • the outer diameter of the axial support disks is selected in such a way that it is larger than the inner diameter of the mounts for the bearing bolts of common cable drums.
  • the respective axial support disk particularly preferably has at least one elastically deformable stop element for a cable drum.
  • the cable drum between the axial support disks is advantageously supported in the axial extension by the stop element. Vibrations during operation can also be avoided and synchronization of the cable drum can be guaranteed.
  • Each axial support disk particularly preferably has a plurality of stop elements distributed evenly over its circumference in order to ensure that the axial support disk or the cable drum is subjected to a uniform force.
  • the respective stop element is preferably designed as an elastomer element, as a result of which a cost-effective realization of the elastically deformable stop element is offered.

  • FIG. 1 shows a perspective view of an advantageous cable drum carrier system 1, which includes a cable drum carrier 2 and a construction machine 3, shown here only in sections, in particular in the form of an excavator.
  • the construction machine 3 has a movable, in particular hydraulically and/or motor-driven, working arm 4, on the free end of which the cable drum carrier 2 is in particular detachably fastened.
  • the cable drum carrier 2 has a crossbeam 5 on which a coupling 6 for the detachable attachment of the cable drum carrier 2 to the working arm 4 of the construction machine 3 is arranged in the middle.
  • the coupling 6 is in particular arranged in the middle in the longitudinal direction of the cross member 5, so that in the mounted state the cross member 5 hangs horizontally aligned on the working arm 4 in equilibrium.
  • Two retaining arms 7 are mounted on the cross member 5 so that they can be displaced in the longitudinal direction of the cross member 5 .
  • the retaining arms 7 have a guide opening 9 at their end 8 facing the cross member 5, through which the cross member 5 protrudes in such a way that the retaining arms 7 are slidably mounted on the cross member 5 in the longitudinal direction of the cross member, as indicated by double arrows 10 in Figure 1 displayed.
  • the crossbeam 5 is designed as an L-beam or double-T beam, so that it has an outer contour that deviates from a circular shape.
  • the inner contour of the guide opening 9 is designed to correspond to the outer contour of the crossbar 5 or to complement it, so that a positive anti-rotation lock is formed between the crossbar 5 and the respective holding arm 7, which prevents one of the holding arms 7 from being pivotable about the longitudinal axis of the crossbar 5 .
  • the mounting of the support arms 7 is designed in such a way that they can only be displaced along the crossbeam 5 in accordance with the arrows 10 in the longitudinal direction thereof.
  • the holding arms 7 At their end 11 facing away from the end 8 , each have a rotatably mounted bearing pin 12 .

  • FIG. 2 shows the cable drum carrier 2 in a simplified side view. It can be seen here that the two bearing bolts 12 on the holding arms 7 are arranged facing one another and aligned with one another. The bearing bolts 12 can thus be rotated about a common imaginary central longitudinal axis or axis of rotation 14 .
  • the respective bearing pin 12 also preferably has an insertion phase 17 on its end facing away from the axial support disk 13 and facing the opposite bearing pin 12 .
  • the respective axial support disk 13 lies on the end of the bearing bolt 2 facing the respective holding arm 7 and carries on its front side 15 facing the respective opposite axial support disk 12 several stop elements 16 which are distributed evenly over the circumference and which are in particular designed to be elastically deformable.

  • the cable drum 18 has a continuous cylindrical receptacle 19 in the middle, into which, for example, a bearing mandrel or, according to the present exemplary embodiment, the respective bearing pin 12 can be pushed in axially in order to thereby carry the cable drum 18 .
  • the cable drum 18 also has side walls 20 which prevent a rolled-up cable from being able to escape laterally from the cable drum 18 . Due to the fact that the holding arms 7 are displaceably mounted on the crossbeam 5, the bearing bolts 12 can be moved towards or away from one another, as shown by a double arrow 21 in FIG.
  • the bearing bolts 12 can be inserted into the receptacle 19 or pulled out of it in a simple manner in order to attach the cable drum 18 to the cable drum carrier 2 or to detach it from it.
  • the cable drum 18 is preferably held axially braced for attachment between the axial support disks 13 , in particular between the stop elements 16 , so that it is firmly locked on the cable drum carrier 2 .
