Definitions

  • the invention relates to a single-head capstan winch for pulling and lifting loads of the type specified in the preamble of claim 1.
  • Such single-head capstan winches are used, for example, in forestry operations for felling and towing trees, since relatively heavy loads can be moved with a relatively low weight of the winch.
  • a device is required for each single-head capstan that generates a clamping force in order to hold the load rope against the lack of the capstan drum.
  • a compression spring To use clamping disc, which can be coupled to the drive shaft of the capstan head by means of drive pawls, in order to obtain an effective clamping groove in relation to the jacket for the rope length running without load only in one direction of rotation.
  • GB-PS 10 35 652 a multi-head capstan winch with an axially parallel deflection pulley emerges, which generates a load-transmitting frictional connection of the load rope firmly anchored at both ends with the jacket of the capstan head.
  • This capstan winch which is designed for higher load transmission, also has pressure rollers that are pretensioned by springs, each of which press only one turn of the load rope onto the jacket for guiding purposes.
  • a single-head capstan winch of the type specified emerges from DE-PS 35 10 282 and has a capstan drum for a multiple looping of a load rope, which is connected at one end to the load and runs at the end load-free, a rope storage for the load-free end of the load rope , a drive motor, a change gear between the drive shaft of the capstan drum and the drive motor as well as a device for generating the clamping force for holding the load rope on the jacket of the capstan drum, namely rotatably mounted rope pressure rollers which have a rotationally symmetrical contact surface that is complementary to the envelope surface of the multiple looping have and are rotatably mounted on a support frame.
  • the rope storage is formed by a rope basket which can be plugged onto the actual single-head capstan winch.
  • a disadvantage of such a single-head capstan winch is the relatively large additional effort for the rope pressure rollers, which have to be manufactured and assembled with small tolerances so that they can perform their function perfectly.
  • the weight of such a single-head capstan winch is not inconsiderably increased, which is particularly noticeable in forestry operations, since such capstan winch often has to be carried over longer distances there.
  • the invention is therefore based on the object of providing a single-head capstan of the type specified, in which the disadvantages mentioned above do not occur.
  • a single-head capstan winch is to be created which, on the one hand, has a comparatively low weight and, on the other hand, generates the required clamping force in a structurally simple manner.
  • the advantages achieved by the invention are based on the utilization of the rope storage generally required, in this case a rope drum, for the generation of the clamping force, in that the rope drum is constantly driven with a relatively small force, namely rotated, by a small pull on the Exercise load rope and thereby generate the clamping force that holds the load rope on the jacket of the capstan drum.
  • the storage drum can be driven by its own drive source, e.g. via a small, battery-powered electric motor
  • the drive motor for the capstan drum also drives the storage drum by supplying the drive force of this drive motor to the storage drum via a separate transmission path.
  • a hydraulic drive serves as the drive motor for the capstan drum
  • a separate branch for driving the storage drum is fed by the pump in addition to the hydraulic branch for the capstan drum.
  • a multi-stage planetary gear is provided which also rotates the storage drum.
  • This planetary gear is housed in a hollow axis of the capstan drum, so it does not require any additional space.
  • the storage drum should be arranged coaxially with the capstan drum, so that the overall result is a very compact structure.
  • both drive types it is possible with both drive types to arrange the storage drum differently, for example axially parallel to the capstan drum, and to provide a separate drive path between the two drums, for example via a belt drive.
  • the rope closure which is otherwise free, is fixed in this single-head capstan winch, expediently on the outer surface of the storage drum.
  • Such single-head capstan winches generally have an automatically acting holding brake with freewheel which automatically locks the capstan drum against reverse, the so-called "dead man's switch”.
  • an additional centrifugal brake can be integrated in the holding brake, which generates a speed-dependent braking torque and thereby automatically prevents such an uncontrolled free fall.
  • capstan drum 12 and storage drum 14 are arranged coaxially to one another.
  • the capstan drum 12 has the usual, concave jacket, on which a load rope 16 is wound in several turns. From the capstan drum 12, the unloaded end of the load cable 16 is guided to the storage drum 14 via a first deflection roller 18 and a second deflection roller 20 arranged axially parallel to the capstan drum 12 and storage roller 14. The end of the rope is attached to the end face of the storage drum 14 by a conventional rope clamp 22.
  • This single-head capstan winch 10 can be attached to any solid object by means of a single-point suspension on an eyelet 24, for example on a tree, a vehicle, a post, an earth nail or the like.
  • the single-head capstan 10 automatically adjusts itself in the "force action line" in the horizontal and vertical direction when the eyelet 24, which is rigidly connected to capstan drum 12 and storage drum 14, is in relation to the direction of force of the load rope indicated by the arrow 16 is located at a corresponding point.
  • An actuating lever 26 to be explained is also indicated in FIG.
  • a drive motor can be used on the single-head capstan winch 10, for example a hydraulic motor, an electric motor or, particularly in the case of forestry operation, an internal combustion engine.
  • a hydraulic motor for example a hydraulic motor, an electric motor or, particularly in the case of forestry operation, an internal combustion engine.
  • FIG. 2 Several basic possibilities of designing such a drive motor are indicated in FIG. 2. Specifically, the drive using an internal combustion engine with a centrifugal clutch 28 is first discussed below (see FIG. 2).
  • Such an internal combustion engine can be started by hand; Only when a higher speed is reached by accelerating, the centrifugal clutch 28 establishes a frictional connection to the change gear, namely a three-stage planetary gear according to FIG.
  • the drive takes place via a central shaft 30, which extends through capstan drum 12 and storage drum 14 and through the entire planetary gear to the sun gear 32 of the first drive planetary stage.
  • the power flow takes place via three planet gears 34 on a planet carrier 36.
  • the resulting low reaction moment is supported on the internally toothed storage drum 14, the inner toothing of which is indicated by reference numeral 38.
  • a further power transmission takes place via the middle planetary stage to the output planetary stage, in which a planet carrier 40, which is formed by a web, is connected to the support housing 42.
  • reaction moments of the middle planetary stage and the last or output planetary stage are directed to the internal toothing 38 of the capstan drum 12.
  • the capstan drum 12 is rotated with the major part of the torque supplied by the drive motor and a correspondingly high force is exerted in the direction of the arrow of FIG. 1 on the load end of the cable 16, while the torque acting on the storage drum 14 is relatively low, however is sufficient to keep the load rope 16 between the capstan drum 12 and the storage drum 14 always slightly tensioned in proportion to the cable pull.
  • Different winding diameters between capstan drum 12 and storage drum 14 are automatically compensated for, and even in the case of a multi-layer winding, the load rope 16 is wound onto the storage drum 14 in a manner that protects the rope.
  • the total rope length depends solely on the winding capacity of the storage drum 14. Since the forces exerted there on the load rope 16 are very low, ten or more rope layers can also be deposited on the storage drum 14 without it being squeezed together and thus resulting in rope damage.
  • a conventional activation with a rotary switch button is provided.
  • the rotary switching button 44 rotates, a stroke is generated on a bolt 46 and the toothing 48 of the planet carrier 46 is thus switched out of the toothing 48 of the sun gear 50.
  • An automatically acting, conventional holding brake is also provided on the drive of this single-head capstan winch, the brake body 52 of which is connected to the drive shaft 56 via a roller-mounted freewheel 54.
  • Several compression springs 58 press the brake body 60 onto the support housing 42 via the brake housing 60. This holding brake with freewheel locks the capstan drum 12 automatically against return, thus serving as a so-called "dead man's switch”.
  • centrifugal bodies 62 in the brake body 52.
  • the spring force of the compression springs 58 is at least partially released and the brake is opened, so that during the stroke -Operation the load can be released.
  • centrifugal bodies 62 are pressed outward into support housing 42, thus generating a speed-dependent braking torque. This ensures a controlled lowering of loads.
  • This hydraulic circuit has the usual structure, so that it will not be explained in detail.
  • a small part of the hydraulic medium supplied by the hydraulic pump 72 is branched off and used to drive the storage drum 14.
  • the distribution of the hydraulic energy between capstan drum 12 on the one hand and storage drum 14 on the other hand takes place in the manner described above, i.e. the major part of the torque is generated on the capstan drum 12, while the torque of the storage drum 14 is sufficient to keep the load rope 16 between capstan drum 12 and storage drum 14 always slightly tensioned in proportion to the cable pull.
  • capstan drum 12 and storage drum 14 have to be arranged coaxially, such a hydraulic drive offers the advantage that the capstan drum can be arranged in a favorable position for the cable drive and the storage drum 14 independently thereof.
  • the storage drum 14 can be attached at any point of the vehicle where there is sufficient space available.
  • the load rope 16 is then guided around deflection rollers at a sufficient distance onto the storage drum 14.
  • Figure 4 finally shows an embodiment of a single-head capstan winch 10 ', the structure and drive essentially corresponds to the embodiment of Figure 2.
  • the storage drum 14 ' is not arranged coaxially to the capstan drum 12 on the central shaft 30, but axially parallel to the capstan drum 12.
  • the drive connection between the central shaft 30 and the storage drum 14' is formed by a belt or chain drive, which is denoted by the reference numeral 80 is indicated.
  • the storage drum 14 'sits axially displaceably on its drive shaft 82 rotated by the belt 80 and can thereby optimally adapt to the position of the load rope 16 on the capstan drum 12.
