Definitions

  • This invention is dedicated to diagnose reliability of ropes in lifting equipment, such as funicular, rope cars, lifts and similar ones.
  • Aim of invention to create new non-destructive method of steel rope diagnostics, intended to use it during equipment exploitation or for independent rope diagnostics; to define necessary additional equipment (in addition to standard) for this method implementation.
  • diagnostic method for steel rope and equipment for this method realization, based on automated finding of broken wires in the rope surface.
  • This method allows simply, using cheap and simple equipment to control one of key rope security parameter - broken wires of rope surface in rope, which is mounted in equipment, for example, loaded by lift cabin or in separated rope.
  • This method differs from existing methods so, that broken wires on rope surface are found by dividing rope into control fragments, tensing the fragment by static force and performing diagnostic measurements in every diagnostic fragment of rope sequentially.
  • every diagnostic rope fragment tensioned by static force, rope rotational - transverse resonant vibrations are excited using vibrator.
  • rope is attached tightly to stiff vibrator body using special clamps.
  • Resonant vibrations of rope creates transverse vibrations of broken ropes on rope surface.
  • These vibrations are registered by original set of sensors; internal surface of sensor set has shape of inner ring surface. This ring surface covers rope with tiny gap.
  • measurement sensor set is moved along rope fragment axis of symmetry and vibrating broken wires inducts signal in set of sensors. Presence of signal informs about presence of broken wires in sensor position of rope fragment. After measurement of fragment, next fragment is diagnosed.
  • figure 1 it is shown proposed variant of realization of diagnostics, when rope is vertical
  • figure 2 it is shown variant, when rope is in horizontal position.
  • Figure 3 shows set of sensors for broken wire vibration measurement.
  • Broken wires are searched in each rope fragment separately, sequentially checking all length of rope.
  • transverse vibrations of rope is excited, which caused rotational vibration of rope and thus rotational vibrations of endings of broken wires.
  • Frequency of vibrations is adjusted so, that vibrations would occur in resonant frequency zone of clamped fragment of rope, for example, lowest rotational vibration resonant frequency.
  • These vibrations cause intensive vibrations of end of broken wires, which are registered using special sensor set.
  • This sensor set has shape of ring and sensitive surface of sensors are turned to internal side and covers rope with small gap.
  • one end of rope 1 is clamped in the support 2 and tensed vertically by makeweight 3, attached to other end of rope.
  • Mass of makeweight 3 is chosen to be close to force during exploitation.
  • Rope is divided separate test fragments (with length Li), diagnostics is performed in one of them.
  • At the ends of frame 4, separated by distance Hi using equipment 5 there is tight clamped fragment of rope 1 of length Hi, which includes test fragment Li .
  • tip of vibrator 6 is pressed down to rope 1 in the distance Ki and using vibrator there are excited transverse vibrations of tightened rope fragment of length Hi, which induces transverse-rotational vibrations of rope.
  • Frequency of exciting vibrations is adjusted so, that rope fragment will vibrate in one of its resonant frequencies, in lowest rotational frequency.
  • set of sensors 9 is moved along sliders 8 of frame 4 so, that axis of symmetry of inner ring surface 10 coincides with axis of symmetry 1 1 of rope 1.
  • set of sensors 9 vibrating free ends of broken wires 13 passes through radial gap ⁇ without touch or, in other case, wires 14 touches them.
  • set of sensors issues the signal, which is processed in the block 15 and registered in block 16, according which signal place of broken wire is fixed and visualized in the test fragment of rope 1.
  • Gap ⁇ between sensitive surface of sensors 27 in the set of sensors 9 is chosen so, that signal from passing vibrating broken wire end would be sufficient to register. After diagnostics of test fragment, grips 5 release tightened fragment of rope 1 and next fragment rope 1 is clamped. The same procedure is repeated for every rope fragment. In this way all length of rope is tested.
  • Frequency of vibrations is chosen so, that it corresponds to on of natural frequencies, for example, lowest rotational natural vibrations.
  • set of sensors 9 are moved along sliders 25 in distance L 2 so, that horizontal axis of symmetry of inner ring surface 10 coincides with axis of symmetry 25 of fragment of rope lwith length H 2 .
  • rope diagnostics of rope fragment of length L 2 are performed in the same manner as shown in fig. 1 defined procedure.

Abstract

La présente invention concerne l'utilisation de diagnostics pour des câbles variés d'équipement de levage. L'objectif de l'invention est de créer un nouveau procédé non destructif relativement simple pour diagnostiquer la qualité de câble, et d'évaluer un équipement spécial destiné à la mise en oeuvre d'un tel procédé. Le procédé selon l'invention est basé sur l'obtention de faits concernant des fils métalliques rompus à la surface du câble. A cette fin, le câble est soumis à une traction par une charge axiale permanente, et à des vibrations transversales qui induisent des vibrations rotatives transversales, à l'aide d'un vibreur. Les oscillations des extrémités libres des fils métalliques rompus sont mesurées par un ensemble de capteurs, et après le traitement des signaux, la présence et les positions des fils métalliques rompus sont détectées. Le vibreur qui sert à faire vibrer le câble et l'ensemble de capteurs sont montés sur une ossature spéciale qui est étroitement serrée sur le câble et sur un fragment de câble séparé. Pendant les vibrations, l'ensemble de capteurs se déplace le long du fragment de câble testé. Cette procédure est répétée pour le fragment de câble suivant jusqu'à ce que le câble soit testé en totalité.
