Definitions
- the invention relates to a lift with a counterweight according to the independent claim.
- an elevator has an elevator car for receiving persons or cargo, which is connected by means of a support and traction means with a counterweight.
- the carrying and traction means runs over a traction sheave, which is driven by a drive.
- the traction sheave divides the carrying and traction means into a first and second carrying and traction means strand.
- the elevator car are suspended on the first and the counterweight on the second support and traction element strand.
- the counterweight serves on the one hand the compensation of the cabin weight and on the other hand to ensure traction between the support and traction means and the traction sheave. This ensures that the traction is sufficient to move the elevator car and, accordingly, the counterweight along a roadway.
- an elevator has at least one elevator body which can be moved along a roadway.
- the elevator body itself has at least one guide element, which is guided by a plurality of vertically superposed with the roadway fixedly connected counterparts of the guide element.
- the guide element is always engaged by at least two counterparts.
- An “elevator body” is understood to mean either an elevator car, a counterweight or the like.
- the advantage of the invention is that the guide element expands substantially only over the length of the elevator body.
- conventional guide elements such as guide rails, which typically extend along the entire carriageway of the elevator body, significant savings can be made in terms of material.
- the carriageway of the elevator is limited in a building predominantly by an elevator shaft, which typically comprises four side walls, a shaft ceiling and a shaft floor.
- the roadway may also be limited by a truss structure. Such structures can, for example, subsequently in a staircase of a Built or built on the outside of a building.
- the counterparts are aligned vertically one above the other on at least one straight line and specify the direction of movement of the guide element or of the elevator body. As a result, a perfect guidance of the elevator body can be achieved.
- a distance of two adjacent counterparts in the direction of travel of the counterweight is less than half the length of the guide element. This ensures that the guide element is engaged at all times with at least two counterparts and is felt in a reliable manner.
- the elevator body has two guide elements which each lie on opposite sides of the elevator body.
- Each of these two guide elements is guided by a plurality of vertically superimposed counterparts.
- the counterparts are arranged in pairs at the same height. This has the advantage that the executives acting between the counterparts and the guide elements are symmetrically introduced into a structure that limits the roadway.
- a guide surface of the counterparts and / or the guide elements is provided with a sliding layer.
- the sliding layer has the advantage that the friction between a counterpart and a guide element is reduced. As a result, less drive energy needed and the wear of these elevator components is smaller. This leads to both a better economic and ecological balance of the elevator.
- the guide element is designed as a rail and a counterpart as a sliding block. Sliding shoes and guide rails are widely used in lift construction guide elements. This has the advantage that cheap and proven standard elements can be used.
- the sliding shoes comprise a guide surface with at least one roller. Since the rolling friction is less than the sliding friction, this role also leads to a reduction in the friction between a shoe and a guide rail.
- a roller may preferably be arranged on one of the end face of the guide rail opposite side of the shoe.
- further rollers may be arranged on at least one side of the sliding shoe opposite the lateral surfaces of the guide rail.
- the sliding shoe comprises at least two, four or six rollers, which are each arranged offset one behind the other in the direction of travel, in order to avoid a rotation of the guide rail about a roller axis.
- the sliding blocks have two insertion regions, in which a guide rail can be inserted.
- the shoes also have a guide area that is flush between the two insertion areas.
- the guide area guides the shoes inserted in the shoe Guide rail.
- a fitting tolerance between the guide rail and the insertion areas is greater than a fitting tolerance between the guide rail and the guide area.
- the fitting tolerance between the guide rail and an insertion area is selected such that the guide rails can be reliably inserted into the sliding blocks, even if vibrations of the elevator body or of a guide rail occur during operation. In particular, it is ensured that a guide rail hits the opening of a sliding shoe.
- Fig. 1 shows an elevator 10, which has an elevator car 5 and a counterweight 2.
- the elevator car 5 and the counterweight via a support and traction means 7 are interconnected.
- both the elevator car 5 and the counterweight 2 are suspended in a suspension ratio of 1: 1.
- the elevator car 5 and / or the counterweight 2 can also be suspended as a bottle in a suspension ratio of 2: 1 or in a higher suspension ratio.
- the support and traction means 7 is typically formed as a rope or belt, which comprise, for example, aramid or steel tensile carriers.
- the support and traction means 7 are in operative contact with a traction sheave 6, which in turn is connected to a drive.
- the drive generates a drive torque which acts on the support and traction means 7 via the traction sheave 6.

Description
Die Erfindung betrifft einen Aufzug mit einem Gegengewicht gemäss unabhängigem Anspruch.The invention relates to a lift with a counterweight according to the independent claim.
Üblicherweise verfügt ein Aufzug über eine Aufzugskabine zur Aufnahme von Personen oder Ladegut, die mittels eines Trag- und Zugmittels mit einem Gegengewicht verbunden ist. Das Trag- und Zugmittel läuft dabei über eine Treibscheibe, die von einem Antrieb angetrieben wird. Die Treibscheibe teilt das Trag- und Zugmittel in einen ersten und zweiten Trag- und Zugmittelstrang. Dabei sind die Aufzugskabine am ersten und das Gegengewicht am zweiten Trag- und Zugmittelstrang aufgehängt. Das Gegengewicht dient einerseits der Kompensation des Kabinengewichts und andererseits der Sicherstellung einer Traktion zwischen dem Trag- und Zugmittel und der Treibscheibe. Dabei wird sichergestellt, dass die Traktion ausreicht, um die Aufzugskabine und dementsprechend auch das Gegengewicht entlang einer Fahrbahn zu verfahren.Typically, an elevator has an elevator car for receiving persons or cargo, which is connected by means of a support and traction means with a counterweight. The carrying and traction means runs over a traction sheave, which is driven by a drive. The traction sheave divides the carrying and traction means into a first and second carrying and traction means strand. In this case, the elevator car are suspended on the first and the counterweight on the second support and traction element strand. The counterweight serves on the one hand the compensation of the cabin weight and on the other hand to ensure traction between the support and traction means and the traction sheave. This ensures that the traction is sufficient to move the elevator car and, accordingly, the counterweight along a roadway.
In der Patentschrift
Daher ist es die Aufgabe dieser Erfindung einen Aufzug mit einer Aufzugskabine und/oder einem Gegengewicht, insbesondere deren Führung, möglichst materialsparend herzustellen.It is therefore the object of this invention to produce an elevator with an elevator cage and / or a counterweight, in particular its guide, as material-saving as possible.
So verfügt ein Aufzug beispielsweise über mindestens einen Aufzugskörper, der entlang einer Fahrbahn verfahrbar ist. Der Aufzugskörper selbst verfügt über mindestens ein Führungselement, das von mehreren senkrecht übereinanderliegenden mit der Fahrbahn ortsfest verbundenen Gegenstücken des Führungselements geführt ist. Dabei liegt das Führungselement stets im Eingriff mindestens zweier Gegenstücke.For example, an elevator has at least one elevator body which can be moved along a roadway. The elevator body itself has at least one guide element, which is guided by a plurality of vertically superposed with the roadway fixedly connected counterparts of the guide element. The guide element is always engaged by at least two counterparts.
Unter einem "Aufzugskörper" wird entweder eine Aufzugskabine, ein Gegengewicht oder dergleichen verstanden.An "elevator body" is understood to mean either an elevator car, a counterweight or the like.
Der Vorteil der Erfindung liegt darin, dass das Führungselement sich im Wesentlichen nur über die Länge des Aufzugskörpers ausdehnt. Dadurch lässt sich im Vergleich mit herkömmlichen Führungselementen wie Führungsschienen, die sich typischerweise entlang der gesamten Fahrbahn des Aufzugskörpers erstrecken, deutlich an Material einsparen.The advantage of the invention is that the guide element expands substantially only over the length of the elevator body. As a result, in comparison with conventional guide elements, such as guide rails, which typically extend along the entire carriageway of the elevator body, significant savings can be made in terms of material.
Die Fahrbahn des Aufzugs ist in einem Gebäude vorwiegend von einem Aufzugsschacht begrenzt, der typischerweise vier Seitenwände eine Schachtdecke und einen Schachtboden umfasst. Desweiteren kann die Fahrbahn auch von einer Fachwerkstruktur begrenzt sein. Solche Strukturen können beispielsweise nachträglich in einen Treppenaufgang eines Gebäudes eingebaut oder auf der Aussenseite eines Gebäudes angebaut werden.The carriageway of the elevator is limited in a building predominantly by an elevator shaft, which typically comprises four side walls, a shaft ceiling and a shaft floor. Furthermore, the roadway may also be limited by a truss structure. Such structures can, for example, subsequently in a staircase of a Built or built on the outside of a building.
Die Gegenstücke sind vertikal übereinander auf mindestens einer Geraden ausgerichtet und geben die Bewegungsrichtung des Führungselements respektive des Aufzugskörpers vor. Dadurch lässt sich eine einwandfreie Führung des Aufzugskörpers erreichen.The counterparts are aligned vertically one above the other on at least one straight line and specify the direction of movement of the guide element or of the elevator body. As a result, a perfect guidance of the elevator body can be achieved.
In einer weiteren Ausführungsform des Aufzugs ist ein Abstand von zwei benachbarten Gegenstücken in Fahrtrichtung des Gegengewichts kleiner als eine halbe Länge des Führungselements. Dadurch wird gewährleistet, dass das Führungselement zu jeder Zeit mit mindestens zwei Gegenstücken im Eingriff steht und dabei auf zuverlässiger Weise gefühlt ist.In a further embodiment of the elevator, a distance of two adjacent counterparts in the direction of travel of the counterweight is less than half the length of the guide element. This ensures that the guide element is engaged at all times with at least two counterparts and is felt in a reliable manner.
In einer weiteren Ausführungsform des Aufzugs verfügt der Aufzugskörper über zwei Führungselemente, die je auf entgegengesetzten Seiten des Aufzugskörpers liegen. Jedes dieser beiden Führungselemente ist von mehreren senkrecht übereinanderliegen Gegenstücken geführt. Die Gegenstücke sind paarweise auf gleicher Höhe angeordnet. Dies hat den Vorteil, dass die Führungskräfte, die zwischen den Gegenstücken und den Führungselementen wirken, symmetrisch in eine Struktur, die die Fahrbahn begrenzt, eingeleitet werden.In a further embodiment of the elevator, the elevator body has two guide elements which each lie on opposite sides of the elevator body. Each of these two guide elements is guided by a plurality of vertically superimposed counterparts. The counterparts are arranged in pairs at the same height. This has the advantage that the executives acting between the counterparts and the guide elements are symmetrically introduced into a structure that limits the roadway.
In einer weiteren Ausführungsform des Aufzugs ist eine Führungsfläche der Gegenstücke und/oder der Führungselemente mit einer Gleitschicht versehen.In a further embodiment of the elevator, a guide surface of the counterparts and / or the guide elements is provided with a sliding layer.
Die Gleitschicht besitzt den Vorteil, dass die Reibung zwischen einem Gegenstück und einem Führungselement reduziert wird. Dadurch wird weniger Antriebsenergie benötigt und der Verschleiss dieser Aufzugskomponenten wird kleiner. Dies führt sowohl zu einer besseren ökonomischen als auch ökologischen Bilanz des Aufzugs.The sliding layer has the advantage that the friction between a counterpart and a guide element is reduced. As a result, less drive energy needed and the wear of these elevator components is smaller. This leads to both a better economic and ecological balance of the elevator.
In einer weiteren Ausführungsform des Aufzugs ist das Führungselement als Schiene und ein Gegenstück als Gleitschuh ausgelegt. Gleitschuhe und Führungsschienen sind im Aufzugsbau weit verbreitete Führungselemente. Dies hat den Vorteil, dass günstige und bewährte Standardelemente eingesetzt werden können.In a further embodiment of the elevator, the guide element is designed as a rail and a counterpart as a sliding block. Sliding shoes and guide rails are widely used in lift construction guide elements. This has the advantage that cheap and proven standard elements can be used.
In einer alternativen Ausführungsform umfassen die Gleitschuhe eine Führungsfläche mit mindestens einer Rolle. Da die Rollreibung geringer ist als die Gleitreibung führt diese Rolle ebenfalls zu einer Verminderung der Reibung zwischen einem Gleitschuh und einer Führungsschiene. Eine solche Rolle kann vorzugsweise an einer der Stirnfläche der Führungsschiene entgegengesetzten Seite des Gleitschuhs angeordnet sein. Desweiteren können alternativ oder ergänzend auch weitere Rollen an mindestens einer den Lateralflächen der Führungsschiene entgegengesetzten Seite des Gleitschuhs angeordnet sein. In einer besonders bevorzugten Ausführungsform umfasst der Gleitschuh mindestens zwei, vier oder sechs Rollen, die jeweils in Fahrtrichtung versetzt hintereinander angeordnet sind, um ein Drehen der Führungsschiene um eine Rollenachse zu vermeiden.In an alternative embodiment, the sliding shoes comprise a guide surface with at least one roller. Since the rolling friction is less than the sliding friction, this role also leads to a reduction in the friction between a shoe and a guide rail. Such a roller may preferably be arranged on one of the end face of the guide rail opposite side of the shoe. Furthermore, alternatively or additionally, further rollers may be arranged on at least one side of the sliding shoe opposite the lateral surfaces of the guide rail. In a particularly preferred embodiment, the sliding shoe comprises at least two, four or six rollers, which are each arranged offset one behind the other in the direction of travel, in order to avoid a rotation of the guide rail about a roller axis.
In einer weiteren Ausführungsform des Aufzugs verfügen die Gleitschuhe über zwei Einführungsbereiche, in welchen eine Führungsschiene einführbar ist. Die Gleitschuhe verfügen zudem über einen Führungsbereich, der fluchtend zwischen den beiden Einführungsbereichen liegt. Der Führungsbereich führt die im Gleitschuh eingeführte Führungsschiene. Dabei ist eine Passtoleranz zwischen der Führungsschiene und den Einführungsbereichen grösser als eine Passtoleranz zwischen der Führungsschiene und dem Führungsbereich.In a further embodiment of the elevator, the sliding blocks have two insertion regions, in which a guide rail can be inserted. The shoes also have a guide area that is flush between the two insertion areas. The guide area guides the shoes inserted in the shoe Guide rail. In this case, a fitting tolerance between the guide rail and the insertion areas is greater than a fitting tolerance between the guide rail and the guide area.
Die Passtoleranz zwischen der Führungsschiene und einem Einführungsbereich ist so ausgewählt, dass die Führungsschienen zuverlässig in die Gleitschuhe einführbar sind, auch wenn Vibrationen des Aufzugskörpers bzw. einer Führungsschiene, im Betrieb auftreten. Insbesondere wird sichergestellt, dass eine Führungsschiene die Öffnung eines Gleitschuhs trifft.The fitting tolerance between the guide rail and an insertion area is selected such that the guide rails can be reliably inserted into the sliding blocks, even if vibrations of the elevator body or of a guide rail occur during operation. In particular, it is ensured that a guide rail hits the opening of a sliding shoe.

In this case, the introduction region has at least two rollers, which are each arranged opposite a lateral side of the guide rail. In addition, optionally, a third roller may be provided, which lies opposite the end face of the guide rail.
