Definitions

  • the invention relates to a spooling device for winding and unwinding a rope according to the preamble of claim 1.
  • the individual windings of the rope should lie directly and firmly next to each other to ensure a good winding pattern.
  • the rope must be offset when being wound onto the rope drum per revolution of the rope drum by approximately the diameter of the rope in the axial direction of the rope drum. This offset of the cable in the axial direction of the cable drum is also referred to as cable pitch.
  • the rope pole is so far away in the direction perpendicular to the axis of rotation of the rope drum that the run-up angle on the flanged wheel of the rope drum can be a maximum of 3°.
  • the rope pole is usually in the middle between the flanged wheels of the rope drum. So that's the angle of attack 3°, the distance between the rope pole and the axis of rotation of the rope drum is at least 9.5 times the distance between the flanged wheels of the rope drum measured in the direction of the axis of rotation of the rope drum.
  • the so-called spooling angle must not be too small so that the rope on the flanged wheel is not wound up on the flanged wheel in several windings one on top of the other instead of running in the other axial winding direction.
  • the spooling angle corresponds to the run-up angle of the rope on the rope drum when the rope has arrived at the flanged wheel. With a spooling angle of 3°, the rope running up on the flanged wheel is pulled away from the flanged wheel again. This arrangement results in a good winding pattern.
  • a disadvantage is the large installation space that such a winding device requires.
  • a spool or swing arm to spool a rope.
  • a bobbin arm is mounted so that it can pivot freely about a pivot axis.
  • the pivot axis is usually arranged in a plane perpendicular to the axis of rotation of the cable drum in the middle of the cable drum.
  • the swivel axis can be arranged much closer to the rope drum than the rope pole with the "+/- 3° spooling principle", which is why this spooling device requires less installation space.
  • the incoming rope is guided along the spool arm to the rope drum.
  • the spool arm has a deflection roller at its end facing the rope drum. From the deflection pulley, the rope runs onto the rope drum at a small angle.
  • the rope is usually deflected by about 90° at the deflection pulley.
  • the rope runs approximately parallel to the pivot axis of the spool arm in the run-up area on the rope drum.
  • the run-up angle of the rope onto the rope drum is determined not only by the pivoted position of the swivel arm, but also by the position of the deflection element relative to the rope drum.
  • the position of the deflection element is defined by the radial distance of the deflection element from the axis of rotation of the cable drum and by the axial distance of the cable drum, measured in the direction of the axis of rotation of the cable drum Deflection element to a center plane of the cable drum.
  • the center plane is oriented perpendicular to the axis of rotation of the cable drum and is located in the middle between the two flanged wheels of the cable drum.
  • the run-up angle is measured in a tangential plane to the rope already wound on the rope drum at the run-up point of the rope on the already wound-up layers of rope against a plane perpendicular to the axis of rotation of the rope drum.
  • the tangential plane is located at a distance from the axis of rotation that corresponds to the mean radius of the outermost coiled layer of rope.
  • a spooling device with a spool arm is arranged in such a way that the run-up angle of the cable is approximately 0° when the cable is deflected by 90° on the deflection roller.
  • This is usually the case with a half-wound rope when the spool arm is positioned in the middle between the two flanged wheels. Due to the pivoting movement of the spool arm about the pivot axis, the deflection roller moves on a circular path with respect to the pivot axis.
  • the deflection angle of the rope at the deflection element changes.
  • the arrangement is typically designed in such a way that the deflection angle becomes smaller when the bobbin arm is pivoted out of the central position. If the spool arm is pivoted out of the middle position, the angle of the rope on the rope drum increases. Due to the positioning of the deflection pulley arranged at the free longitudinal end of the spool arm relative to the cable drum and due to the deflection of the cable on the deflection pulley, the run-up angle can also be kept below 3° with this arrangement, although the distance between the pivot axis and the axis of rotation of the cable drum is smaller than that Distance of the rope pole in a spooling device with a fixed rope pole. With this arrangement, the winding angle can be greater than or equal to 3°.
  • the spooling angle is the take-up angle of the rope when it hits the flanged wheel.
  • the winding angle is ideally 3°.
  • the spooling device with spool arm has a moving rope pole, namely the deflection element.
  • Such a spool arm can only be used to spool a rope onto a storage drum.
  • the majority of the force that is caused by a load hanging on the rope, or a pulling force on the rope, is hereby absorbed by a winch arranged between the load and the storage drum.
  • a winch arranged between the load and the storage drum.
  • a rope drum that is designed as part of the winch is loaded with the maximum pulling force because it is an integral main part of the winch winch itself is.
  • the forces in the rope vary between none and the maximum pulling force of the winch.
  • a winding device with a spool arm is still not compact enough, despite the improvement in this respect over the +/- 3° fixed-pole spooling principle.
  • spooling devices such as e.g. They all have the same function of orderly laying down the rope on the rope drum, namely laying one coil right next to the next so that the rope structure is tight and without gaps, and when changing layers, properly directing the rope away from the flanged wheel and in the opposite direction.
  • the object of the invention is to create a winding device that delivers a good winding pattern in a small installation space.
  • the invention is therefore based on a winding device with a winding arm.
  • the invention is based on the finding that it is difficult or almost impossible for a compact winding device with a swivel arm, which is short because of the desired compactness, to keep the run-up angle of the rope on the rope drum ⁇ 3° over the entire width of the rope drum. Because of the required compactness, the pivoting angle of the pivoting arm must be very large so that the deflection element can be guided close enough to the flanged wheel. Only then should the reverse movement of the rope on a drum of the rope drum take place properly when changing layers.
  • the deflection element is mounted so that it can tilt about a tilt axis that extends along the longitudinal axis of the swing arm extends.
  • the tilting axis extends in the middle of the cable. Due to the tiltability of the deflection element, a run-up angle of the cable on the cable drum of less than 3° is possible over a large angular range, even with a small length of the swivel arm.
  • the spooling device can be of compact design and still spool the cable onto the cable drum with a good spooling pattern.
  • the winding device according to the invention only takes up a small amount of space and still provides a good winding pattern.
  • the pivoting angle of the spool arm can be limited. Due to the tiltable deflection element, a cable exit opening of the cable from the deflection element can be moved closer to the flanged wheel even when the swivel arm is held in place. A small run-up angle is achieved here. A small winding angle is achieved here.
  • the critical angle range is in particular a continuous angle range.
  • the critical angle range is expediently at most 135°, in particular at most 90°, preferably at most 70°, particularly preferably at most 60°.
  • the drum of the cable drum has a radius.
  • the distance between the pivot axis and the axis of rotation of the cable drum is expediently more than the radius of the drum of the cable drum.
  • the distance between the pivot axis and the axis of rotation of the cable drum is in particular less than twice, preferably less than 1.5 times the radius of the drum of the cable drum.
  • the limiting element is in particular part of the winding device and is designed independently of the cable drum. Due to the ability of the deflection element to tilt, the deflection element can continue to follow the cable running onto the cable drum even when the swivel arm is in contact with the limiting element. Due to the lower pivoting angle due to the limiting element and due to the tiltability of the deflection element, a good winding pattern can be achieved even with a compact design of the spool arm. In particular, despite the short length of the spool arm or the pivotable part of the spooling device, a spooling angle of approximately 3° can be achieved. Despite the short length of the spool arm or the swiveling part of the spooling device, the run-up angle of the rope can be less than 3°.
  • the spooling device is particularly suitable for winding and unwinding as well as for a multi-layer cable assembly.
  • the spooling device is particularly suitable for both pulling and hoisting winches, where higher safety standards have to be met.
  • the winding device is expediently designed for tensile applications with forces from 10 kN to 1000 kN, in particular from 50 kN to 500 kN.
  • the spooler is useful designed for lifting applications with forces from 1kN to 100 kN, in particular from 10kN to 50 kN.
  • the swivel arm expediently has a cable window.
  • a rope can run through the rope window.
  • the rope is fed to the swivel arm through the rope window when it is being wound up.
  • the swivel arm is designed in such a way that the cable is guided from the cable window to the deflection element along the swivel arm.
  • the combination of a tiltable deflection element with a limiting element enables a compact construction of the winding device with a good winding pattern at the same time.
  • the winding device can be designed in such a way that the cable can be guided through the cable guide into a region of the cable drum outside the limit angle range even when the swivel arm is in a position at the edge of the limit angle range due to the tiltable deflection element. In this way, a collision of the pivotable part of the winding device with one of the two flanged wheels or the cable structure can be avoided.
  • the part of the rope that is wound onto the drum of the rope drum in particular in multiple layers, is referred to as the rope assembly.
  • the rope can be unwound from the rope drum with the winding device according to the invention.
  • the compactness of the winding device according to the invention which is made possible by the limiting element and the ability to tilt the deflection element, is also advantageous for this application.
  • the winding device is advantageously designed in such a way that the deflection element can be tilted about the tilting axis in such a way that the rope can be guided by the deflection element into an angular range outside the limit angle range.
  • an arm length of the pivot arm measured perpendicularly to the pivot axis, can be small and a good winding pattern can nevertheless be achieved.
  • the swiveling part of the cable guide has a swiveling length measured perpendicular to the swiveling axis, starting from the swiveling axis. Due to the fact that the cable can be guided from the tiltable deflection element into the angle range outside the limit angle range, the pivoting length can be small and a good winding pattern can nevertheless be achieved.
  • the deflection element is arranged in a tilted position with respect to the tilting axis.
  • the swivel arm is arranged in a swivel position with respect to the swivel axis.
  • the deflection element can be freely tilted about the tilting axis in any pivoting position of the pivoting arm.
  • the winding device comprises an adjusting means, and that the adjusting means specifies the tilted position as a function of the pivoted position.
  • the winding device can be designed in such a way that the cable is wound onto the cable drum with continuous feed in the direction of the axis of rotation of the cable drum.
  • the winding device can be designed in such a way that the cable is wound onto the cable drum with continuous feed in the direction of the axis of rotation of the cable drum, independently of the guidance by a pretensioned cable.
  • the feed in the direction of the axis of rotation of the cable drum is then even and continuous, independent of the pretension and guidance by the cable.
  • the rope can be wound up in the critical angle range with a predetermined take-up angle.
  • the spooling device can be designed in such a way that a good spooling pattern is obtained independently of a force acting on the cable, for example due to a load.
  • the spooling device can be designed in such a way that a good spooling pattern is obtained even with variations in the size of the load.
  • the force on the rope is 2% of the minimum breaking strength of the rope.
  • the deflection element advantageously runs freely in the edge positions of the critical angle range. In particular, the deflection element runs freely in every pivoting position of the pivoting arm.
  • the deflection element is positively controlled in the critical angle range. Provision can be made for the deflection element to be positively controlled in each pivoting position of the pivoting arm.
  • the winding device is designed in such a way that in the edge position of the swivel arm there is a maximum tilting angle of the deflection element.
  • the winding device is designed in such a way that there is a stepless transition with respect to the tilted position of the deflection element between a smallest and the largest tilt angle when the swivel arm is swiveled.

  • the connecting rod is expediently rotatably mounted on the pin.
  • the swivel gear in particular the crank drive, is preferably designed in such a way that the distance between the shaft axis and the journal varies when the journal moves around the shaft axis. This allows irregularities to be compensated which would otherwise result from the arrangement of the connecting rod if the journal were guided on a circular path.
  • the distance between the shaft axis and the journal is expediently varied during the movement of the journal around the shaft axis in such a way that a constant advance results when the rope is wound up on the rope drum.
  • the distance between the shaft axis and the journal is varied during the movement of the journal around the shaft axis in such a way that a constant rope pitch is achieved when the rope is wound up on the rope drum.
  • the rope pitch is the offset of the rope in the direction of the axis of rotation of the rope drum.
  • the spooling device is designed in such a way that the swivel arm rotates by 100% to 110% of the rope diameter of the rope, in particular by 100% to 105% of the rope diameter of the rope, preferably by 100% to 102% of the rope diameter, during one rotation of the rope drum about the axis of rotation of the rope is offset in the direction of the axis of rotation of the rope drum.
  • the swivel gear expediently has a cam disc with a track in which the pin is guided on its way around the shaft axis.
  • the cam disk is fixed relative to a rotary disk of the swivel gear.
  • the turntable is expediently rotatable about the shaft axis by means of the swivel gear.

  • the multiple rollers are arranged next to one another on a cam track. This enables a compact deflection of the rope.
  • the rope is only exposed to a small mechanical load.
  • the angle of wrap of the cable around each of the several pulleys is at most 25°, expediently at most 15°, advantageously at most 10°, preferably at most 5°.

  • the link pin 30 is at a distance from the deflection element 7 measured in the direction of the axis of rotation 50 .
  • the link pin 30 is inserted through a link track 32 of the link guide 29 .
  • the link track 32 is an opening in the link guide 29 that completely penetrates the link guide 29 in the direction of the tilting axis 47.
  • the tilting axis 47 can be swiveled in a swiveling plane S about the swiveling axis 48 .
  • the pivoting plane S is perpendicular to the pivoting axis 48.
  • the link pin 30 is arranged with its central axis in the pivoting plane S.
  • the link track 32 runs obliquely to the pivot plane S.
  • the tilting element 31 becomes deflected when it is deflected of the link pin 30 is tilted out of the pivoting plane S.
  • the pivot arm 6 is pivoted about the pivot axis 48 from the center plane M towards one of the two edge regions of the limit angle range ⁇ , in particular towards one of the two flanged wheels 4, the deflection element 4 is continuously tilted further and further around the tilt axis 47.
  • the sliding track 32 has a continuous course.
  • a link path can also be provided which has a discontinuous course which causes an abrupt change in the tilted position of the deflection element 7 .
  • the adjusting means 9 causes the tilting position of the deflection element 7 to depend on the pivoting position of the swivel arm 6.
  • the adjusting means can also be realized in any other conceivable way.
  • a separate drive can be provided for tilting the deflection element 7, which is coordinated with the swivel drive via a control unit.
  • the tilted position of the deflection element 7 is realized by a gear connection with the swivel drive.
  • the forced control of the tilting of the deflection element 7 can also be implemented, for example, via a thrust member that is mounted tiltable about an axis that extends parallel to the line of intersection in 13 shown center plane M and the pivot plane S extends.
  • a base point of the deflection element can only be in one plane parallel to the in 13 Move shown swivel plane S.
  • the deflection element 7 is pivoted to the same extent as the thrust member about the pivot axis of the thrust member.
