Abstract

The device has a solenoid wound around a haulage cable, in which a current impulse passes through the solenoid to magnetize a specific-point at the haulage cable for setting a bench-mark in the cable. The haulage cable is demagnetized when an alternating current flows through the solenoid. The specific point that is magnetized is detected by magnetic field sensors that are arranged around the specific point.

Description

Das Förderseil von Seilförderanlagen wird durch das Spleißen zu einem Endlosseil zusammengefügt. Manche Fahrbetriebsmittel dürfen nicht auf den Spleiß aufgekuppelt oder aufgeklemmt werden.
Damit das Aufkuppeln auf den Spleiß gesperrt werden kann, muß Spleißanfang und Spleißende markiert werden.The rope of rope conveyors is joined by splicing into an endless rope. Some driving equipment must not be coupled or clamped onto the splice.
To prevent the coupling from being spliced onto the splice, splice beginning and splice end must be marked.

Die Fahrbetriebsmittel von Seilförderanlagen müssen vor dem Regelhaltepunkt die Fahrt verlangsamen und präzise am Regelhaltepunkt stehen bleiben.
Bei automatisch betriebenen Seilförderanlagen wird der Fahrtverlauf vom Start bis zum Regelhaltepunkt durch ein mechanisches oder elektronisches Kopierwerk gesteuert.
Im Kopierwerk ist die Abbildung der Fahrstrecke, also der Fahrtverlauf gespeichert.The means of transport of cable transport systems must slow down the journey before the rule stop point and remain precisely at the rule stop point.
For automatically operated cable transport systems, the course of the journey from start to normal stop is controlled by a mechanical or electronic copier.
The copy of the route, ie the route is stored in the copier.

Wenn der Streckenpunkt im Kopierwerk (das Kopierwerkfenster) nicht mit dem Festpunkt der Fahrstrecke übereinstimmt, wird die Seilförderanlage gestoppt.If the waypoint in the copier (the copier window) does not coincide with the fixed point of the route, the cable conveyor will be stopped.

Wenn der Streckenpunkt außerhalb des Kopierwerkfensters erscheint, wird die Seilförderanlage gestoppt. Das Kopierwerk und die Festpunkterkennung überwachen sich also gegenseitigIf the waypoint appears outside the copier window, the rope conveyor is stopped. The photocopier and the fixed point detection thus monitor each other

Bekannt sind:

  1. 1. Markierungen einer Seilstelle durch eine radioaktive Einlage die im Inneren des Seiles eingelegt werden muß. Zum Beispiel eine Kapsel mit Co60.
    Die Detektion erfolgt im Durchstrahlverfahren mit einem Geigermüller Zählrohr.
  2. 2. Markierungen durch das Einbringen von mehreren metallischen Einlagen im Inneren des FörderseilesFörderseilmittelpunkt, der meistens durch eine nichtmetallische Einlage ausgefüllt ist.
    Der Nachweis der markierten Seilstelle erfolgt mit Seilprüfgeräten, die Strukturveränderungen im Förderseil erkennen (siehe z.B. die Einrichtung der FR-A-2 817 819).
    Durch die bestimmte Anordnung der metallischen Einlagen kann das Seilprüfgerät die markierte Stelle zu anderen Strukturveränderungen, Störstellen, im Förderseil unterscheiden.
Are known:
  1. 1. Markings of a cable point by a radioactive insert which must be inserted in the interior of the rope. For example, a capsule with Co60.
    Detection is carried out using a Geigermüller counter tube.
  2. 2. Markings by the introduction of several metallic inserts inside the hoist rope center, which is mostly filled by a non-metallic insert.
    The detection of the marked rope location is carried out with rope testing equipment which detects structural changes in the hoisting rope (see eg the device of FR-A-2 817 819).
    Due to the specific arrangement of the metallic inserts, the cable testing device can distinguish the marked point from other structural changes, defects, in the hoisting rope.

Markierungen im Förderseil nach 1. und 2. sind sehr aufwendig durch den Umstand, daß:

  • Zum Einlegen gemäß 1. und 2. ein längerer Betriebsstillstand erforderlich ist und das Einlegen nur von
    Spezialisten durchgeführt werden kann.
  • Zum Einlegen nach 1. und 2. das Förderseil geöffnet werden muß
  • Die Markierung nach 2. relativ breit ist
  • Die Seilstruktur durch die Einlagen im Seil, verändert wird
  • Die Position der Markierung nach 1. und 2. nur unter großem Aufwand verschoben werden kann, zum Beispiel nach Seilkürzungen oder wenn das Fahrbetriebsmittel gegenüber dem Seil versetzt werden muß
Markings in the rope 1 and 2 are very complicated by the fact that:
  • To insert according to 1. and 2. a longer shutdown is required and the insertion of only
    Specialists can be performed.
  • To insert after 1. and 2. the hoisting rope must be opened
  • The marking after 2. is relatively wide
  • The rope structure through the deposits in the rope, is changed
  • The position of the marker after 1. and 2. can be moved only with great effort, for example, after cable cuts or when the driving equipment must be offset from the rope

Die erfindungsgemäße Einrichtung setzt die Markierung an die vorgesehene Stelle im Förderseil, durch die Magnetisierung des Förderseiles.
Die markierte Stelle wird mit einem Magnetfeldsensor detektiert.
Unerwünschte magnetische Stellen im Förderseil werden durch eine Entmagnetisierungseinrichtung beseitigt. Die Vorteile sind:

  • Schnelles Markieren der bestimmten Stelle im Förderseil (Festpunkt setzen mit einem Knopfdruck)
  • Keine längeren Betriebsstillstände zum Markieren der bestimmten Förderseilstelle mit Abspannen, Öffnen des Förderseiles, Einlegen von Metallstücken oder Kapseln mit dem radioaktivem Isotop C60.
  • Keine Eingriffe und Veränderungen am Förderseil
  • Schnelles Löschen einer Markierung (Festpunkt löschen)
  • Schnelles Verschieben der markierten Stelle im Förderseil (Festpunkt verschieben)
  • Keine Seilspezialisten erforderlich
The device according to the invention sets the marking to the intended location in the hoisting rope, by the magnetization of the hoisting rope.
The marked spot is detected with a magnetic field sensor.
Unwanted magnetic spots in the hoisting rope are eliminated by a demagnetizer. The advantages are:
  • Quick marking of the specific position in the hoist rope (fixed point with a push of a button)
  • No longer downtime for marking the designated hoisting rope position with unclamping, opening the hoisting rope, inserting metal pieces or capsules with the radioactive isotope C60.
  • No interventions and changes to the hoisting rope
  • Quick deletion of a mark (delete fixed point)
  • Fast moving of the marked position in the hoist rope (move fixed point)
  • No rope specialists required
