Definitions
- the invention relates to a cable tensioning system for elevators with separate cable and cable hoists according to the driving and carrying function, both of which act on both a car and a counterweight.
- a rope tensioning system In order to maintain a defined cable pull ratio in spite of the rope elongations that occur, a rope tensioning system must be provided which either acts directly on the driving rope or on a pulley that deflects it and retracts the driving rope according to the rope elongations.
- the cable tensioning system has a rocker arm mounted on the counterweight or car, on which the drive cable and the suspension cable are fastened at a distance from one another such that the spacing ratio a: b of the fastening points of these cables on the rocker is based on the mounting point of the Swing arm on the counterweight or car determines the cable pull ratio required for driving ability.
- the driving ability is advantageously no longer determined directly by the weight of the car and counterweight, which enables lighter cars. Because the swing arm of the rope tensioning system is mounted on the counterweight or car, the already existing counterweight is used for rope tensioning and rope length compensation.
- the rocker is designed as a two-sided lever is, then the bearing point of the rocker on the counterweight is located within the attachment points of the drive cable and suspension cable on the rocker, and both strands are led upwards.
- the rocker is designed in the form of a one-sided lever, in which case the rocker bearing point on the counterweight or car lies outside the attachment points of the two cables on the rocker and the drive cable is at the bottom is led.
- the rocker arm can be designed in the form of a simple lever or, as preferred, with segments in the form of a segment of a circle, the carrying cable and the driving cable being each guided over peripheral circular arcs of the segments of the circle, the radii of which correspond to the lever arms a and b of the rocker.
- a damping element is provided between the bearing point and the rocker which dampens the unwanted rotary movements of the rocker.
- the length of the lever arms a and b of the rocker is adjustable.
- the rope tensioning system according to the invention in connection with the closed rope system and the functional separation of the ropes according to the driving and carrying function, allows the engine to be installed at any height next to or directly below or above the shaft, without the entire number of cables having to be guided through the shaft.
- a support rope 11 attached to the upper part of a car 12 is guided via deflection rollers 25 and 26 to a counterweight 13, where it is attached to a rocker 20 of the rope tensioning system coming from above.
- a traction cable 10 is attached to the lower part of the car 12 and is guided from below to the counterweight 13 via a deflection roller 24, a traction sheave 23 and a further deflection roller 22. It can be seen that the drive cable 10 is attached to the rocker 20 at an attachment point 32 and the support rope 11 to the rocker 20 at an attachment point 31.
- the rocker arm 20 is mounted on the counterweight 13 by means of a bearing point 21.
- the bearing point 21 of the rocker 20 lies outside of the attachment points 32 and 31 of the drive cable 10 and the support cable, respectively 11, so that the rocker 20 acts as a one-sided lever.
- the rocker 20 has the shape of two concentric circular segments, the radius of the circular arc of the smaller segment corresponding to the lever arm b of the articulation point 31 on the rocker 20 and the radius of the larger circular segment corresponding to the lever arm a of the fastening point 32 of the drive cable 10 on the rocker 20.
- the drive cable 10 is guided over a circular arc with the radius a and the support cable 11 over a circular arc with the radius b so that the fastening points 32 and 31 of the support cable 11 and the drive cable 10 remain constant in their vertical orientation and thus the drive cable 10 between its deflecting roller 22 and its point of application on the rocker 20 and the support cable 11 between its deflecting roller 26 and its attachment point 31 on the rocker 20 always run vertically.
- FIG. 2 The embodiment shown in FIG. 2 is identical to the embodiment shown in FIG. 1 except for the construction of the rocker 20.
- the rocker has the shape of a cantilever, the bearing point 21 is, however, as in the embodiment in Fig. 1 outside of the attachment points 31 and 32 of the support rope 11 and the drive rope 10.
- the distances a and b of the attachment points 32 of the The driving rope 10 and 31 of the supporting rope 11 on the rocker 20 determine, just as in the embodiment in FIG. 1, the cable pull ratio required on the counterweight to maintain the driving ability.
- the rocker 20 transmits a force component defined by the lever ratio a: b from the fastening point 32 to the traction cable 10, which acts as a load-dependent cable tensioning force for the traction cable 10.
- the rocker arm 20 is designed as a two-sided lever, the bearing point 21 of the rocker arm 20 being located on the counterweight 13 between the fastening points 32 and 31 of the drive cable 10 and the support cable 11, respectively. Starting from these attachment points 32 and 31, the drive cable 10 and the support cable 11 are each guided over circular, circular end faces of the rocker 20, the radii of which correspond to the lever arms a and b of the rocker 20.
- the rocker 20 like the rocker 20 of the first embodiment shown in FIG. 1, has the advantage that the rope pivot point remains aligned in the vertical direction even when the rocker changes angularly.
- FIG. 4 corresponds to the embodiment shown in FIG. 3 with regard to the cable guide and the upper position of the engine, as represented by the traction sheave 23. Only the construction of the rocker 20 is different. It has the shape of a balance beam without the aforementioned circular arc-shaped peripheral sections.
- a damping element is preferably provided for damping unwanted rotary movements of the rocker, such as can occur in the case of movement disorders, for example in counterweight jumping.
- lever ratio a: b of the rocker 20 of the rope tensioning system according to the invention can be adjusted by a suitable device, whereby an adjustment of the rope tension ratio is possible at the place of use.

Abstract
Description
Die Erfindung betrifft ein Seilspannsystem für Aufzüge mit nach Treib- und Tragfunktion getrennten Treibseil- und Tragseilzügen, welche beide sowohl an einem Fahrkorb, als auch an einem Gegengewicht angreifen.The invention relates to a cable tensioning system for elevators with separate cable and cable hoists according to the driving and carrying function, both of which act on both a car and a counterweight.
Bei üblichen Aufzugsanlagen, bei denen Tragseilzug und Treibseilzug getrennt sind, wird das Treibseil durch eine zwischen dem Fahrkorb und dem Gegengewicht vorgesehene Treibscheibe angetrieben und über eine oder mehrere Umlenkrollen umgelenkt, während das Tragseil lediglich die Tragfunktion erfüllt und nicht angetrieben ist. Beim Betrieb der Aufzugsanlagen insbesondere bei in Hochhäusern eingebauten Aufzugsanlagen, bei denen die Seillänge des Treibseils einige 100 m betragen kann, treten erhebliche Seillängungen im Treibseil auf, welche sich nachteilig auf die zwischen Treibscheibe und Treibseil herrschenden Kraftverhältnisse, das sogenannte Seilzugverhältnis auswirken können. Um trotz der auftretenden Seillängungen ein definiertes Seilzugverhältnis beizubehalten, muß man ein Seilspannsystem vorsehen, welches entweder auf das Treibseil direkt oder auf eine dieses umlenkende Rolle einwirkt und das Treibseil entsprechend den Seillängungen nachspannt.In conventional elevator systems, in which the carrying cable and the driving cable are separated, the driving cable is driven by a traction sheave provided between the car and the counterweight and deflected via one or more deflection rollers, while the carrying cable only fulfills the carrying function and is not driven. When operating the elevator systems, particularly in elevator systems installed in high-rise buildings, in which the rope length of the traction rope can be a few 100 m, considerable rope elongations occur in the traction rope, which can have a disadvantageous effect on the force relationships between the traction sheave and the traction rope, the so-called rope pull ratio. In order to maintain a defined cable pull ratio in spite of the rope elongations that occur, a rope tensioning system must be provided which either acts directly on the driving rope or on a pulley that deflects it and retracts the driving rope according to the rope elongations.
Es ist deshalb Aufgabe der Erfindung ein Seilspannsystem für Aufzüge so vorzusehen, daß es die im Betrieb des Aufzugs auftretenden Seillängungen in einem geschlossenen Seilsystem ausgleichen kann, daß die Seilkräfte so gering wie möglich gehalten werden können und daß das den Erhalt der Treibfähigkeit erforderliche Seilzugverhältnis sichergestellt werden kann.It is therefore an object of the invention to provide a rope tensioning system for lifts so that it can compensate for the rope elongations occurring in the operation of the elevator in a closed rope system, that the rope forces can be kept as low as possible and that the rope tension ratio required to maintain the driving ability is ensured can.
Die Aufgabe wird bei einem durch den Oberbegriff des Schutzanspruches 1 angegebenen Seilspannsystem erfindungsgemäß durch die in dessen kennzeichnendem Teil angegebenen Merkmale gelöst.The object is achieved according to the invention in a rope tensioning system specified by the preamble of protection claim 1 by the features specified in its characterizing part.
Demgemäß weist das Seilspannsystem eine am Gegengewicht oder Fahrkorb gelagerte, als Hebel ausgebildete Schwinge auf, an der das Treibseil und das Tragseil im Abstand von einander so befestigt sind, daß das Abstandsverhältnis a:b der Befestigungspunkte dieser Seile an der Schwinge bezogen auf den Lagerungspunkt der Schwinge am Gegengewicht oder Fahrkorb das zur Treibfähigkeit erforderliche Seilzugverhältnis bestimmt.Accordingly, the cable tensioning system has a rocker arm mounted on the counterweight or car, on which the drive cable and the suspension cable are fastened at a distance from one another such that the spacing ratio a: b of the fastening points of these cables on the rocker is based on the mounting point of the Swing arm on the counterweight or car determines the cable pull ratio required for driving ability.
Dadurch wird die Treibfähigkeit vorteilhafterweise nicht mehr unmittelbar durch das Gewicht von Fahrkorb und Gegengewicht bestimmt, was leichtere Fahrkörbe ermöglicht. Dadurch daß die Schwinge des Seilspannsystems am Gegengewicht oder Fahrkorb gelagert ist, wird das ohnehin vorhandene Gegengewicht zur Seilspannung und zum Seillängenausgleich genutzt.As a result, the driving ability is advantageously no longer determined directly by the weight of the car and counterweight, which enables lighter cars. Because the swing arm of the rope tensioning system is mounted on the counterweight or car, the already existing counterweight is used for rope tensioning and rope length compensation.
Im Falle, daß die Treibscheibe des Triebwerks oben liegt, ist es zu bevorzugen, daß die Schwinge als zweiseitiger Hebel ausgebildet ist, wobei dann der Lagerungspunkt der Schwinge am Gegengewicht innerhalb der Befestigungspunkte von Treibseilzug und Tragseilzug an der Schwinge liegt, und beide Seilstränge sind nach oben geführt.In the event that the drive pulley of the engine is at the top, it is preferred that the rocker is designed as a two-sided lever is, then the bearing point of the rocker on the counterweight is located within the attachment points of the drive cable and suspension cable on the rocker, and both strands are led upwards.
Wenn andererseits die Treibscheibe des Triebwerks unten liegt, ist es zu bevorzugen, daß die Schwinge in Gestalt eines einseitigen Hebels ausgeführt ist, wobei dann der Lagerungspunkt der Schwinge am Gegengewicht oder Fahrkorb außerhalb der Befestigungspunkte der beiden Seilzüge an der Schwinge liegt und das Treibseil nach unten geführt ist.If, on the other hand, the traction sheave of the engine is at the bottom, it is preferable that the rocker is designed in the form of a one-sided lever, in which case the rocker bearing point on the counterweight or car lies outside the attachment points of the two cables on the rocker and the drive cable is at the bottom is led.
Die Schwinge kann in Gestalt eines einfachen Hebels oder, wie bevorzugt mit kreissegmentförmigen Abschnitten ausgeführt sein, wobei der Tragseilzug und der Treibseilzug jeweils über periphere Kreisbögen der Kreissegmentabschnitte gefuhrt sind, deren Radien jeweils den Hebelarmen a und b der Schwinge entsprechen.The rocker arm can be designed in the form of a simple lever or, as preferred, with segments in the form of a segment of a circle, the carrying cable and the driving cable being each guided over peripheral circular arcs of the segments of the circle, the radii of which correspond to the lever arms a and b of the rocker.
Zur Beherrschung ungewollter Drehbewegungen der Schwinge infolge Laufstörungen oder Gegengewichtspringens ist zwischen dem Lagerungspunkt und der Schwinge ein Dämpfungselement vorgesehen, welches die ungewollten Drehbewegungen der Schwinge dämpft.In order to control unwanted rotary movements of the rocker due to running disturbances or counterbalance jumping, a damping element is provided between the bearing point and the rocker which dampens the unwanted rotary movements of the rocker.
Damit das Hebelverhältnis der Schwinge am Einsatzort der Aufzugsanlage eingestellt werden kann, ist zu bevorzugen, daß die Lange der Hebelarme a und b der Schwinge einstellbar ist.So that the lever ratio of the rocker can be adjusted at the place of use of the elevator system, it is preferable that the length of the lever arms a and b of the rocker is adjustable.
Das erfindungsgemäße Seilspannsystem gestattet es im Zusammenhang mit dem geschlossenen Seilsystem und der Funktionstrennung der Seile nach Treib- und Tragfunktion das Triebwerk in jeder Hohe neben dem Schacht oder direkt darunter oder darüber anzubringen, ohne daß dabei die gesamte Seilanzahl durch den Schacht geführt werden muß.The rope tensioning system according to the invention, in connection with the closed rope system and the functional separation of the ropes according to the driving and carrying function, allows the engine to be installed at any height next to or directly below or above the shaft, without the entire number of cables having to be guided through the shaft.
Die Erfindung wird im folgenden in mehreren Ausführungsbeispielen anhand der Zeichnung naher beschrieben. Es zeigen:
- Fign. 1 - 4
- schematisch vier verschiedene Ausführungsarten des erfindungsgemäßen Seilspannsystems.
- Fig. 1 - 4
- schematically four different embodiments of the rope tensioning system according to the invention.
Bei der in Fig. 1 dargestellten ersten Ausführungsart ist ein am oberen Teil eines Fahrkorbs 12 befestigtes Tragseil 11 über Umlenkrollen 25 und 26 zu einem Gegengewicht 13 geführt, wo es von oben kommend an einer Schwinge 20 des Seilspannsystems befestigt ist. Ein Treibseil 10 ist am unteren Teil des Fahrkorbs 12 angebracht und über eine Umlenkrolle 24, eine Treibscheibe 23 und eine weitere Umlenkrolle 22 von unten zum Gegengewicht 13 geführt. Es ist ersichtlich, daß das Treibseil 10 an der Schwinge 20 an einem Befestigungspunkt 32 und das Tragseil 11 an der Schwinge 20 an einem Befestigungspunkt 31 befestigt sind. Die Schwinge 20 ist mittels eines Lagerungspunktes 21 am Gegengewicht 13 gelagert.In the first embodiment shown in FIG. 1, a
Der Lagerungspunkt 21 der Schwinge 20 liegt außerhalb der Befestigungspunkte 32 und 31 jeweils des Treibseils 10 und des Tragseils 11, so daß die Schwinge 20 als einseitiger Hebel wirkt.The
Die Schwinge 20 hat die Gestalt zweier konzentrischer Kreissegmente, wobei der Radius des Kreisbogens des kleineren Segments dem Hebelarm b des Anlenkpunkts 31 an der Schwinge 20 und der Radius des größeren Kreissegments dem Hebelarm a des Befestigungspunkts 32 des Treibseils 10 an der Schwinge 20 entspricht. Auf diese Weise wird das Treibseil 10 über einen Kreisbogen mit dem Radius a und das Tragseil 11 über einen Kreisbogen mit dem Radius b so geführt, daß die Befestigungspunkte 32 und 31 jeweils des Tragseils 11 und des Treibseils 10 in ihrer vertikalen Ausrichtung konstant bleiben und somit das Treibseil 10 zwischen seiner Umlenkrolle 22 und seinem Angriffspunkt an der Schwinge 20 und das Tragseil 11 zwischen dessen Umlenkrolle 26 und dessen Befestigungspunkt 31 an der Schwinge 20 immer vertikal laufen.The
Die in Fig. 2 dargestellte Ausführungsform ist bis auf die Konstruktion der Schwinge 20 mit der in Fig. 1 dargstellten Ausführungsform identisch. In Fig. 2 hat die Schwinge die Gestalt eines Kragbalkens, der Lagerungspunkt 21 liegt jedoch wie bei der Ausführungsform in Fig. 1 außerhalb der Befestigungspunkte 31 und 32 jeweils des Tragseils 11 und des Treibseils 10. Die Abstande a und b jeweils der Befestigungspunkte 32 des Treibseils 10 und 31 des Tragseils 11 an der Schwinge 20 bestimmen genauso wie bei der Ausführungsart in Fig. 1 das am Gegengewicht zur Erhaltung der Treibfähigkeit erforderliche Seilzugverhältnis. Die Schwinge 20 überträgt eine durch das Hebelverhältnis a:b definierte Kraftkomponente vom Befestigungspunkt 32 auf das Treibseil 10, welche als lastabhängige Seilspannkraft für das Treibseil 10 wirkt.The embodiment shown in FIG. 2 is identical to the embodiment shown in FIG. 1 except for the construction of the
Bei der in Fig. 3 dargestellten Ausführungsart liegt anders als bei den Ausführungsarten gemäß den Fign. 1 und 2 das Triebwerk oben, wie es durch die Lage der Treibscheibe 23 angegeben ist. Bei dieser Ausführungsart werden das Treibseil 10 und das Tragseil 11 von der Schwinge 20 nach oben abgezogen. Die Schwinge 20 ist als zweiseitiger Hebel ausgeführt, wobei sich der Lagerungspunkt 21 der Schwinge 20 am Gegengewicht 13 zwischen den Befestigungspunkten 32 und 31 jeweils des Treibseils 10 und des Tragseils 11 befindet. Ausgehend von diesen Befestigungspunkten 32 und 31 sind jeweils das Treibseil 10 und das Tragseil 11 über kreisbogenförmige periphere Stirnseiten der Schwinge 20 geführt, deren Radien jeweils den Hebelarmen a und b der Schwinge 20 entsprechen. Somit hat die Schwinge 20 ebenfalls wie die Schwinge 20 der in Fig. 1 dargestellten ersten Ausführungsform den Vorteil, daß dar Seilanlenkpunkt auch bei Winkelanderungen der Schwinge in vertikaler Richtung ausgerichtet bleibt.In the embodiment shown in FIG. 3 is different than in the embodiments according to FIGS. 1 and 2 the engine above, as indicated by the position of the
Die in Fig. 4 dargestellte Ausführungsform entspricht hinsichtlich Seilführung und der oberen Lage des Triebwerks, wie sie durch die Treibscheibe 23 dargestellt ist der in Fig. 3 dargestellten Ausführungsart. Lediglich die Konstruktion der Schwinge 20 ist untersciedlich. Sie hat die Gestalt eines Waagebalkens ohne die zuvor erwähnten kreisbogenförmigen peripheren Abschnitte.The embodiment shown in FIG. 4 corresponds to the embodiment shown in FIG. 3 with regard to the cable guide and the upper position of the engine, as represented by the
Bei allen anhand der Fign. 1 bis 4 dargestellten Ausführungsformen ist bevorzugt ein Dämpfungselement zur Dämpfung ungewollter Drehbewegungen der Schwinge vorgesehen, wie sie bei Bewegungsstorungen zum Beispiel beim Gegengewichtspringen vorkommen können.With all based on the fig. 1 to 4 illustrated embodiments, a damping element is preferably provided for damping unwanted rotary movements of the rocker, such as can occur in the case of movement disorders, for example in counterweight jumping.
Allen vier beschriebenen und anhand der Fign. 1 bis 4 dargestellten Ausführungsarten des erfingungsgemäßen Seilspannsystems ist der Vorteil eigen, daß das Hebelverhältnis das zur Treibfähigkeit erforderliche Seilzugverhältnis unmittelbar bestimmt und daß das letztere nicht mehr unmittelbar vom Gewicht des Fahrkorbs und des Gegengewichts beeinflußt ist. Dadurch sind leichtere Fahrkorbe möglich.All four described and based on the fig. 1 to 4 shown embodiments of the rope tensioning system according to the invention has the advantage that the lever ratio directly determines the rope pull ratio required for the driving ability and that the latter is no longer directly influenced by the weight of the car and the counterweight. This makes lighter cars possible.
In sinnvoller Weiterbildung der Erfindung kann vorgesehen sein, daß das Hebelverhältnis a: b der Schwinge 20 des erfindungsgemäßen Seilspannsystems durch eine zweckmäßige Vorrichtung einstellbar ist, wodurch am Einsatzort eine Justierung des Seilzugverhältnisses möglich wird.In a useful further development of the invention it can be provided that the lever ratio a: b of the
