Definitions

  • the invention relates to a device for winches, in particular high-performance winches, for regulating the tensile force of a rope, a defined run-off area being arranged via a rope guide device and the winch having a controllable winch drive, which has a controller and measuring elements and an evaluation device, taking into account the tensile force of the rope is adjustable.
  • winches such as drum winches with a driven traversing device or double capstan winches
  • the drive of the winch can be controlled by a controller so that there is no increased rope load.
  • a control device for cable winches for maintaining a predetermined cable pulling force has become known.
  • a cable control with a sensor arrangement in the form of a cable pulley is connected upstream of the cable drum in order to keep cable cable fluctuations small.
  • this arrangement represents an independent unit that requires multiple additional rope deflections and measures the rope tension in a straight rope.
  • Such a design is often not usable for reasons of space and is relatively complex.
  • hydraulic winches it is also known to regulate the hydraulic working pressure to take. This is sufficient in many cases, especially with capstan winches, if a certain hysteresis between working pressure and tractive effort is accepted.
  • the object of the invention is to improve a generic device and to enable precise and safe traction control in a simple manner with an integrated arrangement which ensures a compact design.
  • the cable pulling force or a defined part of the cable pulling force is advantageously recorded and used by reshaping the recorded value and comparing it with a target value for the corresponding control of the winch drive.
  • the evaluation device derives the correction variable for the working pressure from the determined deviation. In this way, predetermined target values for the tensile force can be maintained with high accuracy, the maximum permissible tensile forces of the respective Ropes can be optimally used without the risk of rope overload.
  • a favorable design is also created through the use of load measuring bolts as part of the winch mounting.
  • load measuring bolts for a two-part mounting of the winch in the tensile load area, it is advantageous if a load measuring pin is provided for the more heavily loaded part of the winch bearing and at least part of the winch bearing is formed by a spherical bearing. This advantageously reduces interference forces, for example as a result of tilting movements, in such a bearing arrangement.
  • a second sensor is provided for the detection of the rope entry position and a third sensor for the detection of wound rope layers.
  • the respective position of the rope entry and the number of rope layers on the drum are advantageously taken into account for the control of the pulling force of the winch, the values detected by the second and third sensors being taken into account accordingly in an evaluation device when converting the load pin force to the rope force .
  • the capstan winch 10 shown has two spills 11 and 12, which are mounted in a winch housing 13.
  • a winch housing 13 For the housing 13, an underside or vertical mounting is provided via a bearing lever 14 which is articulated on a bracket 15 which is fastened on a foundation 16.
  • the housing 13 is also mounted on a vertical wall 17 via a cable guide bracket 18 by means of bolts 19 and 20.
  • the rope guide bracket 18 spatially defines the entry of a rope 21 into the winch 10.
  • the bolts 19 and 20 lie in the plane in which the rope 21 enters the winch 10. They thus transmit the reaction forces from the rope force in a ratio of 1: 1 to the rope guide bracket 18 and the wall 17.
  • the winch 10 is thus supported by the bolts 19 and 20 and by the bearing lever 14, the bearing lever 14 having the task of the winch To keep 10 in their horizontal position, and wherein the bearing lever 14 is arranged so that forces acting in it exert no or only a minimal reaction to the forces acting in the cable pulling direction in the bolts 19 and 20.
  • the no-load rope end 22 emerges from the winch and is stored in a drum (not shown).
  • the winch 10 also has, as shown in FIG. 2, hydraulic lines 23 and 24 which are provided for the corresponding controllable winch drives 25 and 26, respectively.
  • a controller that is able to control the hydraulic drives 25 and 26 in the range of permissible cable tensile forces has been omitted from the illustration.
  • the bolt 19 takes over the larger portion and the bolt 20 the smaller portion of the rope force.
  • the bolts 19 and 20 are designed as load measuring bolts. Alternatively, it is also sufficient if only one bolt is designed as a load measuring bolt, it being best for the accuracy of the reaction force detection to use the bolt with the higher load, because here the influence of interference forces, for example from the connection of the hydraulic lines 23 and 24 and the outlet of the no-load rope end 22 is particularly small.
  • FIG. 3 an enlarged plan view of the mounting of the winch 10 in the region of the bolts 19 and 20 is shown in sections.
  • the bolt 19 is designed as a load measuring bolt in a known design. With the load measuring pin 19, shear forces are measured in the two planes 28 and 29. The measurement results are passed from a connection housing 30 via a cable 31 to an electronic unit of a controller (not shown in more detail), in which the actual tractive force is calculated on the basis of the determined values, a comparison with a predetermined tractive force setpoint is carried out and from the deviation with the aid a corresponding one Control of the hydraulic drives 25 and 26 is regulated.
  • the levels 28 and 29 each lie between a side wall 32 of the housing 13 of the winch 10 and tabs 33 and 34 of the cable guide bracket 18.
  • the load measuring pin 19 is axially held by fastening plate 35 and secured against rotation.
  • the measuring direction of the load measuring pin i.e. the direction of great sensitivity to a load coincides with the direction of the rope 21.
  • the bolt 20 which is designed as a simple bearing bolt, is guided through two brackets 36 and 37 of the bearing block 18 and is also secured against rotation by means of a fastening plate 38. Between the tabs 36 and 37, a side wall 39 of the housing 13 of the winch 10 engages the bolts 20.
  • spherical bearings 40 are provided on both bolts 19, 20, which keep any tilting movements due to deformations of the cable guide bracket 18 or the housing 13 of the winch 10 away from the bolts, in particular from load measuring bolts 19.
  • Fig. 4 shows another variant of the inventive concept with a drum winch 41 and a traversing device 42.
  • the drum is mounted between two plates 44 which are fastened with eyes 45 in the tabs 46 of the load-bearing bracket 47.
  • the attachment is carried out with the aid of a bolt 48 and a load measuring bolt 49.
  • the drum 43 is connected to a brake 50 and a drive motor 51.
  • the traversing roller 52 of the traversing device 42 is driven by the drum 43 via a gear drive in the gear case 53.
  • the Traversing roller 52 has groove tracks 54, in which the guide pin of the cable guide 56, which can be pushed back and forth on the rod 55, engages.
  • the transmission ratio between the cable drum 43 and the traversing roller 52 is designed such that the cable 57 is wound on the cable drum 43 in dense layers.
  • the drum winch 41 has a second sensor 58 which e.g. the position of the cable guide 56 relative to the two support eyes 45 and the respectively wound position of the cable 57 on the drum 43 are determined as angular momentum transmitters.
  • the signals from both transmitters 49, 58 are processed in an evaluation and arithmetic unit 59 with one another in accordance with the geometric conditions of the rope inlet and provide an output signal which corresponds to the rope force.
