Definitions

  • the invention relates to a device for winding and unwinding a rope of a winch with an upstream of the rope winch, with respect to the rope winch can be driven or advanced rope conveyor for tensioning the rope between the rope winch and the rope conveyor.
  • the invention is therefore based on the object to design a device for winding and unwinding a rope of a winch of the type described so that with simple constructional means necessary for a uniform winding or unwinding of the rope continuous tensile stress to - or running rope can be ensured.
  • the invention solves the problem in that the cable conveyor consists of two intermeshing, spur gears forming gears, the teeth of which have an outgoing from the tooth head, tapering against the tooth base receiving recess for the rope guided between the two gears, and that the two gears can be resiliently loaded against each other in the engagement area.
  • the cable conveyor consists of two intermeshing gears, which form a cable groove in the area of their teeth through corresponding receiving recesses for the cable, higher tensile forces can also be exerted on the cable guided between the two gears via opposite gears. with a negligible slip, because the meshing gears are resiliently pressed against each other in the engagement area and clamp the rope between them. This rope clamping is supported by the receiving recesses of the teeth tapering towards the tooth base.
  • the rope is pressed according to the wedge effect of the tapering recess cross-section from the teeth of one gear in the receiving recesses of the teeth of the other gear in a radial direction, which ensures the high friction values required for a slip-free transmission of traction, regardless of a possible wrap angle or the diameter of the gears.
  • Such a device for winding and unwinding a rope therefore requires a comparatively small amount of space, which makes these devices particularly suitable for use with winches that are attached to a vehicle.
  • the resilient pressing of the gears against each other can be achieved with different design means. In this context, particularly simple constructional relationships result when one of the two gear wheels is mounted in a spring-loaded rocker arm.
  • Such an arrangement not only brings advantageous guiding conditions for the displaceable gearwheel with it, but also allows the use of a lever transmission for the spring force via the rocker arm, which, with corresponding lever arms, ensures the transmission of force to the rope between the two gearwheels, so that there is little slip Required friction coefficients can be adhered to safely.
  • the device for winding and unwinding a rope can also be used in a simple manner in connection with winding guides for the rope.
  • the gearwheels can be mounted in a carriage which can be moved parallel to a cross spindle for the reciprocating drive of the winding guide for the rope and which is drive-connected to this winding guide. So that with the reciprocating winding guide, the carriage with the gears is driven back and forth.
  • the gearwheels could be driven by a motor mounted on the slide.
  • simpler design conditions result if one of the two gear wheels is axially displaceably mounted on a spline shaft which runs along the slide guide and is driven by a motor.
  • FIG. 1 shows a device according to the invention for winding and unwinding a rope of a winch in a simplified axial section
  • FIG. 2 shows the device in a section along the line II-II of FIG. 1 on a larger scale.
  • the winding drum 1 which is preferably drivable via a hydraulic motor, is mounted in a housing 2 which receives a winding guide 3 arranged in front of the cable drum 1.
  • This winding guide 3 consists of a cross spindle 4 which can be driven as a function of the winding drum 1 and on which a nut 5 is mounted for the reciprocating drive of a slot-shaped cable guide 6, so that the rope 7 to be wound onto the winding drum 1 corresponds to the gradient of the Cable turns on the winding drum 1 is shifted along the drum axis in order to ensure a uniform contact of the individual cable turns against each other.
  • the cable guide 6 is, however, integrated in a carriage 8, which is displaceably mounted in the housing 2 parallel to the cross spindle 4 and comprises a cable conveyor 9, which consists of two meshing gears 10 and 11. These meshing gears 10 and 11 are driven by a hydraulic motor via a spline shaft 12. Since the gear wheel 10 is mounted on the spline shaft 12 in a rotationally fixed but axially displaceable manner via a hub insert 13, the drive of the gear wheels 10 and 11 is not impaired by the reciprocating carriage movement.
  • the teeth 14 of the gearwheels 10 and 11 have receiving recesses 15, which taper from the tooth head and preferably wedge-shaped towards the base of the tooth, which take on the function of a cable groove and allow cable guidance in the engagement area of the two gearwheels 10 and 11, as is particularly the case in FIG. 2 can be removed.
  • the bearing axis 17 for the gear 11 is held in the two side cheeks of a rocker arm 18 which is pivotally mounted about a slide-fixed articulation axis 19 and via a spring 20 from one Belleville spring assembly is acted on so that the two gears 10 and 11 in the engagement area be pressed against each other.
  • the spring preload can be adjusted to the respective requirements via an adjusting screw 21.
  • the carriage 8 is still a conventional cable entry guide, which consists of two mutually perpendicular guide roller pairs 22 and 23.
  • the invention is of course not limited to the illustrated embodiment, because it depends above all on the special design of the cable conveyor 9 from two meshing gears 10 and 11, between which the cable 7 is guided.
  • the winding guide 3 can be dispensed with if a sufficiently large distance can be provided between the gearwheels 10 and 11 on the one hand and the winding drum 1 on the other hand, in order to enable the individual cable turns to be put together without interference.
  • the cross-sectional shape of the receiving recesses 15 of the teeth 14 can be designed differently if only the required frictional engagement is ensured by a corresponding wedge action between the receiving recesses 15 and the cable 7.

Abstract

L'invention concerne un dispositif permettant d'enrouler et de dérouler le câble (7) d'un treuil de manoeuvre, qui comprend un dispositif de transport de câble (9) monté en amont du treuil de manoeuvre et pouvant être entraîné en avant ou en arrière et servant à solliciter le câble (7) en traction entre le treuil de manoeuvre et le dispositif de transport de câble (9). Afin de créer des conditions de construction avantageuses, il est prévu que le dispositif de transport de câble (9) comprenne deux roues dentées (10,11) formant des roues droites, en engrènement mutuel, dont les dents (14) présentent une cavité de réception (15) pour le câble (7) guidé entre les deux roues dentées (10,11), cavité qui part de la tête de la dent et va s'amenuisant en direction du pied de la dent. Il est également prévu que les deux roues dentées (10,11) puissent être sollicitées par ressort l'une par rapport à l'autre, dans la zone d'engrènement.
