Definitions

  • the invention relates to a cable guide for a winch, in particular a hoist, with a winch drum having opposite rope grooves and rotatably mounted in a frame, with movable on at least one rail parallel to the axis of rotation of the winch drum and for aligning at least one pair of rope strands with respect to the assigned rope groove provided guide elements which are connected in opposite directions to one another via coupling means and can be driven by the windable or unwindable cable strands, the rail having at least two tracks which extend in the longitudinal direction of the rail and are arranged one behind the other in the direction of the cable strands and in which the guide elements are each guided and supported.
  • Rope guides of this type are used on windmills which in particular have winch drums with rope grooves in order to prevent the permissible lateral deflection of the hoisting ropes from being exceeded along the axis of rotation of the winch drum; Such distractions occur, for example, by swinging the load or pulling at an angle. Experience has shown that a reduction in the resulting distractions leads to an increase in the lay-on time of the ropes.
  • a generic cable guide in which a rail including the guide elements is pivotally suspended from the winch drum in the immediate vicinity of the tangential run-off points of the cable strands, which largely adjusts the pivoting movement of the rail including the guide elements to the deflection movement of the Rope strands transverse to the axis of rotation of the winch drum and a particularly gentle drive-free guidance of the rope strands enables.
  • the rail has two tracks, one above the other, spaced apart and designed as laterally open channels for guiding one guide element each, the tracks being provided with grooves running in the longitudinal direction of the rail for slide rails guided therein.
  • the invention has for its object to provide a drive-free cable guide for a windmill, in particular a hoist, which enables a gentle winding or unwinding of the rope, especially when the rope is inclined, but at the same time has a very compact design and still is very maintenance-free.
  • the guide elements should be able to move over the entire length of the rail.
  • the coupling means comprise coupling longitudinal beams which can be moved in opposite directions to one another in the longitudinal direction of the rails, each of which is guided in one of the tracks and is supported along the track at at least two spaced points, each coupling longitudinal beam being rigidly connected to one of the guide elements.
  • Each coupling longitudinal member is rigidly connected to exactly one guide element and forms with it a unit which can be moved in the longitudinal direction of the rail and is supported at at least four points, the spacing of the support points being able to be chosen to be relatively large.
  • the rigidly connected unit comprising the longitudinal coupling member and the guide element is guided and supported in various tracks via the guide element, the support and guidance of the Unit is significantly strengthened via the coupling side member.
  • the spacing of the support points of the coupling longitudinal member can be chosen to be relatively large, so that, in particular, there is excellent horizontal stabilization of the guide element, which effectively prevents the guide element from jamming even with large rope forces.
  • the rope guide according to the invention can be implemented in a very compact design. In particular, the design according to the invention makes it possible to move the guide elements over the entire length of the rail.
  • the coupling longitudinal members are designed as toothed racks into which a gearwheel which rotates freely in the rail and connects the coupling longitudinal members engages.
  • a gearwheel which rotates freely in the rail and connects the coupling longitudinal members engages.
  • the pins of the gearwheel can be inserted with play into an opening provided in the rail, which makes it possible to fix the coupling longitudinal members arranged in the tracks in almost any position relative to one another, and in fact without any adjustment effort.
  • Each coupling longitudinal member is expediently supported in the track in the region of the coupling longitudinal member ends via horizontally freely rotatable wheels.
  • the possible large distance between the impellers ensures very good horizontal stabilization of the guide element; the use of rollers ensures smooth running of the guide element.
  • each coupling longitudinal member is guided in the track via at least one vertically freely rotatable support roller to improve the guidance and support of the guide element on the coupling longitudinal member end facing away from the guide element.
  • each guide element is supported in the tracks arranged one behind the other as seen in the direction of the cable strands by means of two support rollers arranged on the guide element.
  • the traces advantageously form support surfaces themselves in the cross-sectional base and / or on the side surfaces.
  • tracks with holding elements which form vertically arranged support surfaces and / or running surfaces running in the longitudinal direction of the rail and horizontally arranged supporting surfaces and / or running surfaces running in the longitudinal direction of the rail. These ensure perfect guidance and support of the guide element within the rail.
  • a particularly dirt-resistant construction of the cable guide is ensured in that the running wheels and the support rollers are at least partially replaced by sliding elements.
  • Fig. 1 shows a rail of a cable guide of a hoist, which has a winch drum, not shown, rotatably mounted in a frame, in the Opposing rope grooves are formed on the surface.
  • the rail 1 has two tracks 2a, 2b, which extend in the longitudinal direction of the rail and are arranged parallel to one another in the direction of the cable strands, which are designed as spaced and laterally open channels and serve to guide two guide elements 3, the tracks 2a, 2b being guided through a web 4 are connected to each other.
  • the guide elements 3 serve to align a pair of rope strands in relation to the assigned rope groove and can be moved in the longitudinal direction of the rail 1 parallel to the axis of rotation of the winch drum and are driven by the rope strands that can be wound or unwound.
  • the guide elements 3 each have a support roller 5a, 5b with a vertical axis of rotation which is freely rotatable at the top and bottom and which are supported in the tracks 2a, 2b arranged one behind the other in the direction of the cable strands.
  • a cable guide channel carrier 6 is fastened to the guide element 3 with a trained cable guide channel.
  • the two guide elements 3 are each rigidly connected to a longitudinal coupling member 7a, 7b, the longitudinal coupling member 7a 7b being designed as toothed racks with teeth pointing towards the middle of the rail.
  • the two longitudinal coupling members 7a, 7b are connected to one another via a gear wheel 8 which is freely rotatably mounted in the rail 1, the pins 10 (FIG. 3) of which are rotatably mounted in the rail.
  • the pins 9 of the gearwheel 8 with radial play 9a are inserted into openings provided for this purpose; the gear wheel can be inserted in almost any position of the coupling longitudinal members 7a, 7b arranged in the tracks relative to one another.
  • the guide elements 3a, 3b are connected to one another in opposite directions via the gearwheel 8 engaging in the teeth of the toothed racks of the coupling longitudinal members 7a, 7b.
  • Each longitudinal coupling member 7a, 7b is supported at the ends by horizontally freely rotatable wheels 10a, 10b in the track 2a or 2b, that is, at two widely spaced points.
  • each coupling longitudinal member 7a, 7b is movably guided and supported on the guide element 3a or 3b via a support roller 11a or 11b which is freely rotatably mounted vertically in the track 2a or 2b in the longitudinal direction of the rail.
  • FIG. 2 shows a cross section according to section line A-A according to FIG. 1.
  • the tracks 2a, 2b form support surfaces 12, 13 in the cross-sectional base and support surfaces 14 on the side surfaces.
  • the tracks 2a, 2b are provided with holding elements which form vertically arranged support surfaces 18, 19 and horizontally arranged running surfaces 20, all of which run in the longitudinal direction of the rails. All the wheels 10a, 10b and all the support rollers 5a, 5b, 11a, 11b are both supported and guided by the support surfaces 12, 13, 14, 18, 19, 20. 2, the web 4, which connects the two tracks 2a, 2b, can be clearly seen.
  • FIG. 3 shows the cross section of the rail 1 in the region of the gear 8; 3, in particular, the interaction of the gearwheel 8 with the coupling longitudinal members 7a, 7b, which are designed as toothed racks, can be removed.
  • the teeth 22 of the gear 8 engage at the top and bottom of the rack of the coupling longitudinal member 7a and 7b, whereby the racks are fixed in their horizontal position to each other.
  • a longitudinal section of the rail along the section line C - C according to FIG. 3 is shown in FIG. 4.
  • Fig. 5 shows a cross section through the rail 1 according to the section line AA in Fig. 1 in an alternative embodiment, wherein all the wheels 10a, 10b and all the support rollers 5a, 5b, 11a, 11b are replaced by sliding elements 23 with a square cross-section ;.
  • the guide elements 3a, 3b are guided and supported by means of the support surfaces 12, 13, 14, 18, 19, 20, the sliding elements 23 sliding along these support surfaces when the guide elements 3a, 3b move.
