Abstract

The individual functions to be tested and monitored on a crane arrangement (5) are detected by a central electronic diagnosis apparatus (3), via parameters which are to be measured. The correct functioning of the system components is assessed, monitored and tested from the input current and the input voltage of the complete system and from a number of control signals. If a defect occurs, a signal is emitted by the diagnosis apparatus (3). <IMAGE>

Description

Technisches Gebiet:

  • Die Erfindung bezieht sich auf eine Vorrichtung zur Durchführung von Wartungs- und Montagearbeiten an einer Krananlage.
Technical field:
  • The invention relates to a device for carrying out maintenance and assembly work on a crane system.

Stand der Technik:State of the art:

Die elektrischen Module einer Krananlage - z.B. Motoren, Umrichter, Schalt- und Steuergeräte - müssen einzeln auf verschiedene Funktionen geprüft werden. Auftretende Defekte müssen lokalisiert und behoben werden. Die Prüfung der einzelnen Module und die Lokalisierung aufgetretender Defekte sind aufwendig.The electrical modules of a crane system - e.g. Motors, converters, switching and control devices - must be checked individually for various functions. Defects that occur must be localized and eliminated. The testing of the individual modules and the localization of defects that occur are complex.

Darstellung der Erfindung:

  • Hier will die Erfindung Abhilfe schaffen. Die in den Patentansprüchen beschriebene Erfindung löst die Aufgabe, eine Vorrichtung zu schaffen, mit deren Hilfe die elektronischen, elektrischen und/oder mechanischen Funktionen einer mehrmotorigen Krananlage/eines mehrmotorigen Kransystems auf Abruf zu testen und im Einsatz ständig zu überwachen sind.
Presentation of the invention:
  • The invention seeks to remedy this. The invention described in the claims solves the problem of creating a device by means of which the electronic, electrical and / or mechanical functions of a multi-engine crane system / a multi-engine crane system can be tested on demand and continuously monitored during use.

Bei der Erfindung werden die einzeln zu testenden und zu überwachenden Funktionen an der Krananlage von einem zentralen Diagnosegerät über zu messende Größen, z.B. den Strom oder die Spannung, erfaßt. Durch mathematische Berechnungen wird aus dem Eingangsstrom und der Eingangsspannung des Gesamtsystems sowie aus einigen Steuersignalen, z.B. Hängetastersteuersignale, Frequenzumrichtersteuersignale, Funkfernsteuerungssignale, die vorschriftsmäßige Funktion der Systemkomponenten überwacht und getestet. Bei einem eventuell auftretenden Defekt wird von dem Diagnosegerät eine Meldung abgegeben, z.B. über Display, Steuerkontakte oder Drucker.In the invention, the functions to be individually tested and monitored on the crane system are controlled by a central diagnostic device via quantities to be measured, e.g. the current or the voltage. The input current and the input voltage of the overall system and some control signals, e.g. Hanging key control signals, frequency converter control signals, radio remote control signals, the correct functioning of the system components are monitored and tested. If a defect occurs, the diagnostic device sends a message, e.g. via display, control contacts or printer.

Kurze Beschreibung der Zeichnung:

  • Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend im einzelnen beschrieben. Die einzige Figur zeigt das Schaltbild einer Krananlage mit zentralem Diagnosegerät.
Brief description of the drawing:
  • An embodiment of the invention is shown in the drawing and will be described in detail below. The only figure shows the circuit diagram of a crane system with a central diagnostic device.

Bester Weg zur Ausführung der Erfindung:

  • Aus einem Netz 1 wird über eine Hauptstromleitung 2, ein zentrales Diagnosegerät 3 und eine Leitung 4 eine elektrische Krananlage 5 mit Eingangsstrom versorgt. Die elektrische Krananlage weist eine Vielzahl von elektrischen Modulen, z.B. Motoren, Umrichter, Schalt- und Steuergeräte, auf. Deren elektrische, elektronische und mechanische Funktion, und damit die Funktion der Krananlage, werden getestet und im Einsatz ständig überwacht. Funktionen der Module in der Krananlage 5 werden über zu messende Größen, z.B. den Strom oder die Spannung, die über die Leitung 2 zugeführt sind, erfaßt.
Best way to carry out the invention:
  • An electrical crane system 5 is supplied with input current from a network 1 via a main power line 2, a central diagnostic device 3 and a line 4. The electrical crane system has a large number of electrical modules, for example motors, converters, switching and control devices. Their electrical, electronic and mechanical function, and thus the function of the crane system, are tested and continuously monitored during use. Functions of the modules in the crane system 5 are detected via quantities to be measured, for example the current or the voltage which are supplied via the line 2.

Über eine Leitung 6 werden die Steuersignale der einzelnen Module, z.B. Hängetastersteuersignale, Frequenzumrichtersteuersignale, Funkfernsteuerungssignale, dem Diagnosegerät 3 zugeführt. In dem Diagnosegerät 3 wird aus dem Eingangsstrom und der Eingangsspannung des Gesamtsystems sowie aus den Steuersignalen die vorschriftsmäßige Funktion der Module der Krananlage berechnet, überwacht und getestet. Bei einem auftretenden Defekt wird von dem Diagnosegerät 3 über eine Leitung 7 eine Fehlermeldung ausgegeben, die kodiert sein kann. Mit der Leitung 7 sind beispielsweise ein Display, Steuerkontakte oder Drucker verbunden.The control signals of the individual modules, e.g. Hanging key control signals, frequency converter control signals, radio remote control signals, supplied to the diagnostic device 3. In the diagnostic device 3, the correct function of the modules of the crane system is calculated, monitored and tested from the input current and the input voltage of the overall system and from the control signals. In the event of a defect, the diagnostic device 3 issues an error message via a line 7, which may be coded. For example, a display, control contacts or printer are connected to line 7.

Gewerbliche Verwertbarkeit:

  • Die Erfindung ist anwendbar bei allen elektrisch betriebenen Krananlagen.
Commercial usability:
  • The invention is applicable to all electrically operated crane systems.
