Definitions

  • the invention relates to a winch, in particular a Seilhubwinde, with a cable groove having at least one cable drum and a cable guide, the cable guide has at least two complementary to a ring base segments, which is guided over at least one engaging element in the cable groove and a torque arm on the winch are supported, and are arranged on the base segments elements for guiding and holding down a rope, wherein the torque arm is selectively fastened to different locations of the base segments.
  • a winch with a cable drum which has a cable guide for a wound on the cable drum rope.
  • the cable drum has a right- or left-handed rope groove for the rope.
  • the cable guide assumes a leadership function and a hold-down function with respect to the rope.
  • the cable guide is essentially formed as a ring, which is guided on the rope grooves and thus in the longitudinal direction of the cable drum.
  • the ring is approximately half divided into two segments, of which the first is called a guide segment and the second as a hold-down segment.
  • Both segments are provided on their inner circular peripheral surface with a thread profile, which is adapted to the profile of the rope groove, in particular their pitch.
  • the split ring is placed on the cable drum; the thread profiles then engage in the rope groove and the ends of the segments are connected to each other via a screw connection. So that the ring does not rotate with the cable drum but mitwandert during winding and unwinding of the rope along the cable drum in the longitudinal direction, this is supported via a torque arm in the form of a short arm to a profile of the winds, which at a distance from the cable grooves Cable drum and runs parallel to the longitudinal direction of the cable drum.
  • the lead segment and the hold-down segment are each to be fulfilled by them Tasks adapted and therefore differ in their design from each other.
  • This increases the variety of parts of the cable guide.
  • the segments of the cable guide are made of plastic. This entails that a separate injection molding tool is required for the guide segment and the hold-down segment. With increasing diameter of the cable drum and the segments are correspondingly larger and the tool costs increase accordingly.
  • the reference D1 relates to a cable guide, which is constructed from a first ring half and a second ring half.
  • the two ring halves are screwed together in the region of a first parting line via a connecting piece and in the region of a second parting line via a connecting plate.
  • On the outer circumference of the ring halves so-called beads are arranged, in which with respect to the circumference of the ring halves evenly spaced recesses are arranged. In the region of the connecting piece these recesses are also provided.
  • the dimensions of the connector are chosen so that the distances below the recesses and recesses are constant.
  • the recesses are formed as elongated holes which extend tangentially to the ring halves in their width and with their opening in the longitudinal direction of the cable drum. These recesses serve to clamp at almost any location designated as a guide piece torque arm. Depending on the location of the desired cable drain point this guide piece can then be along the ring halves and the corresponding recesses and offset. Also, the connection tab has an exit slot for the rope. This exit slot is also limited by the ring halves. Furthermore, additional clamping rings for holding down the rope turns of the rope are provided on the ring halves. This clamping ring is guided over an annular flange in an annular groove in the ring halves.

  • Each individual component is simpler in design and can be specially adapted to its function. It is created a modular structure of the cable guide.
  • the cable guide can be easily adapted to the local conditions such as installation position of the winch and position of the cable drain point. Also, the assembly of the torque arm and the attachment is simplified. In order to fasten the attachments and the torque arm variable at different locations of the base segments, more holes for the attachments and the torque arm are arranged in the base segments, as needed for their final attachment.
  • a stable guidance of the base segments along the cable drum is achieved in that the engagement elements of the base segments are formed as adapted to the contour of the rope groove threads. This guidance is optimized when the Engagement elements extending almost over the entire drum of the drum facing inner surface of the base segments and seen in the longitudinal direction of the cable drum seen at least two sections of the threads are provided one behind the other.
