Definitions

  • the invention relates to a device for preventing slack rope in winches, in particular those for construction hoists, with at least one pivot lever which can be pivoted about an axis provided parallel to the cable drum axis, with a roller which is freely rotatable about its axis at the free end of the pivot lever, the two ends of which at least extend from the cable drum axis have approximately the same distance, with a spring acting on the pivot lever, which holds the roller in contact with the rope, and with an actuating part provided on the pivot lever, which cooperates with a switch controlling the winch motor.
  • a swivel frame which carries at its free end an axis extending parallel to the rope drum axis.
  • a rope pulley is rotatable on this axis and can be moved in the axial direction.
  • the rope pulley can move parallel to the rope drum while the rope is being wound on the rope drum.
  • the problem since this displacement movement is brought about solely by the rope guided over the rope pulley, the problem also arises with low rope tensile forces that the rope pulley is no longer displaced on the axle, but remains at one point on the axle and then the rope is no longer in order is wound onto the rope drum.
  • the axis can become dirty and rusty in rough construction, so that this prevents axial displacement of the pulley.
  • the invention has for its object to provide a device for slack rope prevention in winches, especially those for construction hoists, of the type mentioned, in which an orderly winding of the rope on the rope drum is ensured even with low rope forces.
  • roller axis is rotated about an imaginary axis running through its center and the center of the rope drum axis perpendicular to both axes with respect to the rope drum axis in the direction of lay of the rope by an angle which is approximately half as large as the lay angle of the rope is.
  • the roller axis does not run parallel but at an angle to the cable drum axis. It was found that this inclination of the roller axis means that the rope is no longer deflected in one direction by the roller, even with very low rope tensile forces. This ensures an orderly winding of the rope on the rope drum, with the rope turn lying next to the rope turn.
  • the direction in which the roller axis must be inclined with respect to the rope drum axis depends on the respective direction of lay of the rope.
  • a particularly advantageous embodiment of the invention is that a clamping bar serving as a stop is arranged in the pivoting range of the roller, which extends parallel to the roller axis in the stop position of the roller, such that the rope between the roller and the terminal strip can be clamped in the stop position of the roller.
  • This arrangement has the advantage that the orderly winding of the rope on the rope drum is maintained even when only a very small amount of cable force is acting on the rope, or when e.g. there is no longer any cable pull when the winch is transported. Thanks to the clamping of the rope between the roller and the clamping strip, the rope cannot loosen from the rope drum uncontrolled under its own tension or other forces.
  • the cable drum 1 is rotatable about the cable drum axis A and is one Not shown winch motor driven.
  • the rope 2 can be wound in several layers on the rope drum 1.
  • a roller 3 forms an important part of the device for preventing slack rope.
  • the roller 3 is arranged at the free end of a pivoting lever, which will be discussed in more detail below in the description of the exemplary embodiments illustrated in FIGS. 4-6 and 7-9.
  • the roller 3 is freely rotatable about its axis A1, expediently with the interposition of ball bearings.
  • the two ends of the roller axis A1 should each have the same distance R from the drum axis A.
  • the roller axis A1 in the region of the two cable drum flanges A should have the same distance from the cable drum axis A in each case.
  • the roller axis A1 is not arranged parallel but at an angle to the rope drum axis.
  • the roller axis A1 is rotated about an imaginary axis A2 which runs through its center and the center of the drum axis A and which is perpendicular to the roller axis A1 and the drum axis A, as can be seen in particular from FIG.
  • the direction in which the roller axis A1 must be rotated relative to the drum axis A depends on the direction of lay of the rope 2.
  • the twist always takes place in the direction of lay of the rope, ie in the case of a rope turned to the left in the left direction of rotation counterclockwise and in the case of a right turned rope in the right direction of rotation clockwise.
  • Figures 1 and 2 the arrangement is shown with a left-handed rope.
  • the angle ⁇ by which the roller axis A1 is rotated relative to the cable drum axis A is essentially dependent on the cable construction. It was found that the angle y must be about half as large as the lay angle a of the rope.
  • the impact angle a It is the angle that a tangent T forms to the outer strands L of the rope 2 with the rope axis S. Since the lay length or winding height in the usual ropes used for construction lifts corresponds to about six times the rope diameter, the lay angle a is about 26 °. Accordingly, the angle ⁇ should be approximately 13 ° .
  • a pivot lever 4 is provided, which is preferably pivotable about the cable drum axis A.
  • This pivot lever 4 carries at its free end 4a the roller 3, the axis A1 of which is inclined with respect to the cable drum axis A in the manner described above.
  • a further pivot lever 4 ' can be provided at the other end of the cable drum 1 for mounting the roller axis A1.
  • the first pivot lever 4 is provided with an actuating part 5 which interacts with a switch 6.
  • the switch 6 is arranged in the circuit of the winch motor. When the operating part 5 touches the switch 6, the winch motor is stopped.
  • a torsion spring 7 acts on the pivot lever 4, which exerts a torque in direction B on the pivot lever 4. As a result, the roller 3 is pressed against the rope 2.
  • a clamping bar 8 serving as a stop is also arranged in a stationary manner.
  • the clamping strip 8 is in the same way as the roller axis A1 inclined relative to the cable drum axis A, so that the clamping strip 8 extends parallel to the roller axis in the stop position of the roller 3. In this way, the cable 2 can be clamped on the cable drum between the roller 3 and the clamping strip 8 at any winding degree.
  • the clamping strip 8 expediently has a covering made of rubber or a rubber-like material on its side facing the roller 3.
  • the clamping of the rope 2 between the roller 3 and the clamping bar 8 prevents the rope 2 from loosening on the rope drum 1 if there is no tensile force acting on the rope during assembly, disassembly, conversion or transport of the construction hoist.
  • the cable drum 1 is partially surrounded by a stationary housing 9.
  • the terminal block 8 is connected to this housing 9.
  • the roller axis A1 is arranged in relation to the cable drum axis A in the same manner as was described above with reference to FIGS. 1-3.
  • the cable drum 1 is surrounded by a protective housing 10 which can be pivoted about the cable drum axis A.
  • the roller 3 is mounted on this protective housing 10.
  • the two side flanges 10a of the protective housing 10 act as a "pivot lever".
  • An actuating part 11 is connected to the protective housing 10 and cooperates with the limit switch 12 arranged in the circuit of the winch motor.
  • the pivotable protective housing 10 has only a narrow slot 13 for the passage of the rope 2, so that very good accident protection is created.
  • a stationary clamping strip 8 ' is provided which interacts with the roller 3.
  • the terminal block 8 ' is firmly connected to the support frame of the cable winch, not shown, by suitable means 14.
  • the protective housing 10 pivots clockwise.
  • the actuating part 11 presses the switch 12 and stops the winch motor.
  • the cable 2 is clamped between the clamping strip 8 'and the roller 3.
