Description
Die Erfindung geht aus von einer Aufzugsanlage mit im Aufzugsschacht angeordneter Antriebseinheit und Steuerungseinheit nach dem Oberbegriff des ersten Anspruches.The invention relates to an elevator installation with an elevator shaft arranged in the drive unit and control unit according to the preamble of the first claim.
Üblicherweise wurden für Aufzugsanlagen spezielle Maschinenräume verwendet, welche insbesondere die Antriebseinheit und die Steuerungseinheit aufnahmen. Dies bedingte jedoch einen zusätzlichen Maschinenraum, z.B. auf dem Dach des Gebäudes, was erhebliche zusätzliche Kosten verursachte. Deshalb wurden Aufzugsanlagen vorgeschlagen, welche keinen separaten Maschinenraum aufweisen, indem die Antriebseinheit und die Steuerungseinheit im Schachtraum angeordnet wurde.Usually, special machine rooms have been used for elevator systems, which housed in particular the drive unit and the control unit. However, this necessitated an additional engine room, e.g. on the roof of the building, which caused considerable additional costs. Therefore, elevator systems have been proposed which do not have a separate machine room by the drive unit and the control unit was arranged in the shaft space.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Aufzugsanlage mit im Aufzugsschacht angeordneter Antriebseinheit und Steuerungseinheit der eingangs genannten Art, eine einfache Wartung der Steuerungseinheit bei höchstmöglicher Sicherheit und möglichst günstigen Anlagekosten zu gewährleisten.The invention is based on the object, in an elevator system arranged in the elevator shaft drive unit and control unit of the type mentioned to ensure easy maintenance of the control unit with the highest possible safety and the best possible investment costs.
Erfindungsgemäss wird dies durch die Merkmale des ersten Anspruches erreicht.According to the invention this is achieved by the features of the first claim.
Kern der Erfindung ist es also, dass die Steuerungseinheit über Mittel von der Betriebsposition in eine nur innerhalb des Aufzugsschachtes zugängliche Wartungsposition bringbar ist.The core of the invention is thus that the control unit via means of the operating position in a only within the elevator shaft accessible maintenance position can be brought.
Die Vorteile der Erfindung sind unter anderem darin zu sehen, dass die Steuerungseinheit innerhalb des Aufzugschachtes in eine leicht zugängliche Wartungsposition gebracht werden kann, die jedoch nur innerhalb des Schachtes zugänglich ist. Dadurch werden die Nachteile des Standes der Technik überwunden, da einerseits die Steuerungseinheit wie auch die Antriebseinheit leicht zugänglich sind und andererseits eine hohe Sicherheit gewährleistet werden kann, da unbefugte Personen keinen Zugang von aussen zur Steuerungseinheit haben. Weiter ist die erfindungsgemässe Ausführung im Vergleich zu bekannten Anordnungen sehr kostengünstig.The advantages of the invention include the fact that the control unit can be placed within the elevator shaft in an easily accessible maintenance position, which, however, is accessible only within the shaft. As a result, the disadvantages of the prior art are overcome, since on the one hand the control unit as well as the drive unit are easily accessible and on the other hand a high level of security can be ensured since unauthorized persons have no access from the outside to the control unit. Further, the inventive design is very inexpensive compared to known arrangements.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the dependent claims.
Es ist vorteilhaft, die Steuerungseinheit über einen Klappmechanismus herunterzuklappen und so den Zugang zur Steuerungseinheit und zur Antriebseinheit zu ermöglichen.It is advantageous to fold down the control unit via a folding mechanism and thus to allow access to the control unit and the drive unit.
So ist es zweckmässig, wenn die Steuerungseinheit und die Antriebseinheit als eine kompakte Einheit ausgebildet werden, da dadurch der Einbau vereinfacht und die Bauhöhe reduziert werden kann.Thus, it is expedient if the control unit and the drive unit are formed as a compact unit, as this simplifies the installation and the height can be reduced.
Es ist zudem besonders vorteilhaft, dass durch die Steuerungseinheit in Wartungsposition ein bereits vorhandener Notendschalter betätigt wird und die Kabine blockiert. Somit kann die Kabine nicht mehr nach oben bewegt werden, wodurch das Wartungspersonal vor einem unbeabsichtigten Fahren der Kabine geschützt wird. Die bekannten und bisher verwendeten zusätzlichen Sicherheits- und / oder Überwachungskontakte müssen deshalb nicht mehr verwendet werden.It is also particularly advantageous that an already existing emergency limit switch is actuated by the control unit in the maintenance position and blocks the car. Thus, the car can not be moved upwards, thereby protecting the maintenance personnel from accidental driving of the car. The known and previously used additional safety and / or monitoring contacts must therefore no longer be used.
