Definitions

  • the invention relates to a device for holding and tensioning ropes, ropes or wires, particularly in as sheet, downdraft or anchor winches, in tackle or pulleys by means of conical disks which are connected to one another in a fixed or drive manner and which are motorized or by hand via a crank or a cable can be driven and which have a surface profile, with only one loop of the traction means.
  • the self-clamping surface profile consists of circular, wavy ribs, the profile divisions of the upper and lower conical disks against one another are offset.
  • the profile can be placed in an arc shape or straight against the pulling direction.
  • this pin in a springy manner in the direction of tension in the wrap direction in order to achieve the maximum possible wrap on the one hand, and on the other hand to reduce the wrap by returning the pin against the spring pressure and thus to enable the tensioning means to be loosened.
  • the pin or the roller and the scraper are preferably arranged at approximately the same distance from the longitudinal axis of the drum. They can also be combined in one element.
  • the scraper has a wedge-shaped protuberance that projects into the keyway between the conical disks, but at a distance from them.
  • the distance to the bottom of the groove should be max. correspond to the thickness of the rope or rope to be tensioned. This provides precaution against multiple wrapping of the drum and thus prevents dangerous overruns.
  • the winch 100 shown in FIG. 1 is basically known from DE 26 02 629 C3.
  • a drum 11 consisting of two rotatably mounted conical disks 111, 112 is rotatably known, in the groove of which a cable 110 can be inserted.
  • the drum 11 has a drive head 12 with a recess 13 into which a ratchet crank, not shown in the drawing, can be inserted.
  • a locking mechanism can also be used which, depending on the crank rotation, releases the desired direction of rotation, but blocks the opposite direction when the crank is released and vice versa.
  • an arm, a roller or a pin 15 and a wiper 16 are arranged parallel to the axis of rotation of the drum 11 and at a short distance from the keyway of the conical disks.
  • the latter has a wedge-shaped protuberance 17 which projects into the keyway 18 between the conical disks 111 and 112, but at a distance from the keyway base 181. The distance should be smaller than the thickness of the rope or rope 110 to be tensioned.
  • the drum 11 consists of an upper conical disc 111 and a lower conical disc 112, which are centered by a bushing 113, which at the same time allows adjustment to different rope diameters by changing their height and is connected by screws 19 and are rotatably arranged relative to the base body 10.
  • the rotatable mounting is known from the prior art, so that there is no need to go into this further.
  • the wrap pin 15 is shown offset in the plane of the drawing.
  • the upper conical disk 111 shown in FIGS. 3a-c has on its inside 111a a straight or curved profile, which consists of radiating, rounded webs.
  • Their pitch t corresponds to about half to a rope strength and their profile is offset by 1/2 t to the lower cone pulley 112.
  • the profiles are either inward, like 111a, c, d or circular like 111e, but always in such a way that the divisions of the upper against the lower are offset by 1/2 division. It can be useful for certain rope designs to ensure grip, to combine two profile designs, i.e. to produce overlap, e.g. 111a, c, d with 111e. For the same reasons, the angle alpha of the conical pulley profiles can be adapted to the rope version.
  • the profiles 111 and 112a, c, d change their cross section over their course, as shown in FIGS. 3d and 3e.
  • the waves forming the profiling have a distance t which, depending on the circumference, increases to a distance T in the region of the edge 111b.
  • the profile 111c does not change in cross section.
  • the lower conical disk 112 shown in Fig. 4a-c has holes 23 for the passage of the screws 19, furthermore, like the upper conical disk 111, a central bore 24 to 25 for receiving the drive head 12 or a hollow shaft in order to rotate the drum 11 to ensure relative to the base body 10.
  • the profiling 112a, c, d of the lower conical pulley corresponds with regard to the profile profile and the orientation of the profiling 111a, c, d with the proviso that it runs in opposite directions in the case of double-acting winds.
  • the profiling 111a, c, or 112a, c, on the one hand ensures that the rope is guided in the direction of rotation with respect to the groove base 181, while the opposing profiling on the opposite side increases the frictional action of the tensioning means inserted.
  • the direction of pull is designated Z here.
  • the bottom of the groove 181 is formed by a cylinder liner which centers both conical disks and with which the distance is adjusted for different rope strengths.
  • FIG. 5 shows a violin block 200 in a side view and in section to illustrate an application of the invention, the pinch roller being identified by 201 and the wrap-around pin being identified by 202.
