Aufzugelevator
Die Erfindung betrifft einen Aufzug mit einem stark exzentrisch an einem Tragmittelsatz in loser Rolle 2:1 aufgehängten Fahrkorb und mit einem mindestens aus einem Motor, einer Treibscheibe und einer Bremse gebildeten Antrieb.The invention relates to an elevator with a highly eccentric to a support means set in a loose roll 2: 1 suspended car and with a drive formed at least from a motor, a traction sheave and a brake.
Ein stark exzentrisch in sogenannter Rucksackaufhängung aufgehängter Fahrkorb ist beispielsweise aus der EP 0 706 969 Bl, EP 1 024 105 AI, WO 99/33 742 AI, und JP 2000-7253, DE 195 46 590 C2 und DE 100 64 850 C2 , A bekannt.A highly eccentrically suspended in so-called backpack suspension car is for example from EP 0706969 Bl, EP 1 024 105 AI, WO 99/33 742 AI, and JP 2000-7253, DE 195 46 590 C2 and DE 100 64 850 C2, A known.
Fahrkörbe in Rücksackaufhängung haben den großen Vorteil, dass sie von drei Seiten zugänglich sind und damit in mit Aufzügen nachzurüstenden Gebäuden sehr variabel einsetzbar sind.Carriages in rear suspension have the great advantage that they are accessible from three sides and are therefore very variable in buildings to be retrofitted with elevators.
Gemäß WO 99/33 742 AI, JP 2000-7253 und DE 100 64 850 C2 sind Kabine und Gegenlast in 1:1 Aufhängung umlenkrollenfrei über eine im oberen Bereich des Schachtes zwischen einer benachbarten Schachtwand und der Fahrkorbrückwand oder der vertikalen Verlängerung dieses Bereiches aufgehängt, indem die Seile über eine Treibscheibe geführt und unmittelbar an dem Fahrkorb und an der Gegenlast angeschlagen sind. Dies erfordert einen kräftigen getriebelosen Antrieb.According to WO 99/33 742 A1, JP 2000-7253 and DE 100 64 850 C2 cabin and counter load are hung in a 1: 1 suspension pulley over a in the upper part of the shaft between an adjacent shaft wall and the car rear wall or the vertical extension of this area, by guiding the ropes over a traction sheave and struck directly on the car and on the counter load. This requires a powerful gearless drive.
Bei den Aufzügen nach EP 0 706 969 Bl, EP 1 024 105 AI und DE 195 46 590 C2 erfolgt die Seilführung so, dass von einem oberen Seilanschlag das Seil nach unten läuft, an einer am Fahrkorb fest installierten Umlenkrolle umkehrt, über die Treibscheibe wieder nach unten geführt ist, an einer an der Gegenlast fest installierten Rolle umkehrt und schließlich mit dem zweiten Ende im Schachtkopf an einem zweiten Seilanschlag befestigt ist. Anstelle nur einer Rolle an Fahrkorb und der Gegenlast können selbstverständlich auch zwei Rollen vorgesehen sein. Mit dieser Tragseilführung wird eine 2:1 Aufhängung realisiert, die es prinzipiell erlaubt, kleinere, schnell laufende, getriebelose Antriebe mit einem verfügbaren halben Drehmoment im Vergleich zu einer 1:1 Aufhängung einzu- setzen. Solche Antriebe lassen sich, da das Drehmoment eines Motors proportional zum Quadrat seines Durchmessers ist, in einem triebwerksraumlosen Schacht aufgrund des geringeren Durchmessers des Antriebs problemloser unterbringen.In the elevators according to EP 0 706 969 B1, EP 1 024 105 AI and DE 195 46 590 C2, the cable guide is carried out so that from an upper rope stop the rope runs down, reverses on a permanently installed on the car deflection pulley, on the traction sheave again is guided downwards, reverses on a roller fixedly mounted on the counterweight and finally attached to the second end in the shaft head on a second cable stop. Of course, instead of only one roller on the car and the counter-load, two rollers be provided. With this suspension cable guide a 2: 1 suspension is realized, which in principle allows to use smaller, high-speed, gearless drives with an available half torque compared to a 1: 1 suspension. Such drives, because the torque of a motor is proportional to the square of its diameter, can be accommodated more easily in a machine roomless shaft due to the smaller diameter of the drive.
Außerdem ist es für Aufzüge mit zentrischer und 1:1 Aufhängung des Fahrkorbs sowie Aufstellung der Antriebsmaschine in einem separaten Triebwerksräum bekannt, zur Erhöhung der Treibfähigkeit die Treibscheibe unter Verwendung einer Gegenscheibe doppelt mit einem Tragseilsatz zu umschlingen (DE 24 41 992 AI, EP 0100 072 A2) .In addition, it is known for elevators with centric and 1: 1 suspension of the car and installation of the prime mover in a separate engine room, to increase the driving ability of the traction sheave using a counter-disc with a supporting cable set to wrap around (DE 24 41 992 AI, EP 0100 072 A2).
Der Erfindung liegt die Aufgabe zugrunde, ausgehend von einer 2:1 Aufhängung für rücksackgeführte Fahrkörbe, eine trieb- werksraumlose Installation eines getriebelosen Aufzugsantrie- bes für verschiedene Fälle beengter Schachtverhältnisse anzubieten.The invention is based on the object, starting from a 2: 1 suspension for baggage-driven cars, to offer an engine room-less installation of a gearless elevator drive for different cases of cramped shaft conditions.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterentwicklungen geben die abhängigen Ansprüche an.The object is achieved by the features of claim 1. Advantageous further developments indicate the dependent claims.
Aufgrund der 2 : 1 Aufhängung und der Anordnung einer Gegenscheibe zur Treibscheibe wird eine besonders kleine Bauweise auch für Aufzüge in Rucksackbauweise möglich, die eine platz- günstige Anordnung im Schachtkopf, das heißt, ohne einen zusätzlichen Triebwerksraum, vorzugsweise ermöglicht.Due to the 2: 1 suspension and the arrangement of a counter-disc to the traction sheave, a particularly small design is also possible for backpack-type elevators, which preferably allows a space-favorable arrangement in the shaft head, that is, without an additional engine compartment.
Zusätzlich lassen sich mit Veränderung der parallelen Achslage von Treibscheibe und Gegenscheibe im Raum, mit Veränderung des Befestigungspunktes der Fahrkorb-Umlenkrolle und mit geeigneter Einpassung der Gegenlast zwischen die benachbarte Schachtwand und die Fahrkorbrückwand, vielfältigste Anpassun- gen an vorhandene Aufzugsschächte vornehmen, was insbesondere beim Austausch veralteter oder verschlissener Anlagen mit modernen Anlagen ein wesentlicher technisch-wirtschaftlicher Aspekt ist .In addition, with a change in the parallel axis position of the traction sheave and counter-disc in space, with a change in the attachment point of the cage deflection roller and with a suitable adaptation of the counter-load between the adjacent shaft wall and the rear wall of the vehicle, the most diverse adaptations can be made. conditions to existing elevator shafts, which is an essential technical-economic aspect especially when replacing obsolete or worn equipment with modern facilities.
Die Erfindung soll anhand eines Ausführungsbeispiels näher erläutert werden. In den zugehörigen Zeichnungen zeigen:The invention will be explained in more detail with reference to an embodiment. In the accompanying drawings show:
Fig. 1 schematisch eine erste triebwerksraumlose Anordnung eines Antriebs in einem AufzugsSchacht,1 shows schematically a first arrangement without a drive train in a drive shaft in an elevator shaft,
Fig. 2 schematisch eine weitere triebwerksraumlose Anordnung eines Antriebs in einem Aufzugsschacht und Fig. 3 schematisch eine dritte triebwerksraumlose Anordnung eines Antriebs in einem Aufzugsschacht .2 is a schematic view of a further machine roomless arrangement of a drive in an elevator shaft, and FIG. 3 is a schematic view of a third arrangement without a drive train in a lift shaft.
Gemäß der Figuren 1 bis 3 umschlingt nacheinander ein im oberen Bereich eines Aufzugsschachtes 1 beidendig angeschlagener Tragmittelsatz 2 eine an einer Gegenlast 3 befestigte Gegenlast-Umlenkrolle 4, eine Treibscheibe 5 des Antriebs, eine zu der Treibscheibe 5 des Antriebs achsparallel angeordnete Gegenscheibe 6 des Antriebs, nochmals die Treibscheibe 5 und die Gegenscheibe 6 des Antriebs und eine an einem Traggestell 7 für einen Fahrkorb 8 in Rucksackaufhängung befestigte Fahrkorb-Umlenkrolle 9. Damit ist eine 2:1 Aufhängung von Gegenlast 3 und Fahrkorb 8 sowie eine doppelte Umschlingung der Treibscheibe 5 des Antriebs 5, 6 realisiert. Der Antrieb 5, 6 wird aus einem nicht sichtbaren getriebelosen Motor, einer koaxial zur Motorwelle bzw. auf einer gemeinsamen Welle angeordneten Treibscheibe 5, einer nicht näher dargestellten Bremseneinrichtung, die auf den Motor und/oder die Treibscheibe 5 arbeitet, und die Gegenscheibe 6 gebildet. Der Motor wird mit Hilfe eines Frequenzumrichters geregelt und übernimmt im Regelbetrieb auch das Abbremsen und den Halt des Fahrkorbs 8. Die Gegenscheibe 6 dient zugleich als Ablenk- scheibe für den Tragmittelsatz 2 bezüglich seiner Führung in Richtung Fahrkorb-Umlenkrolle 9. Der oder die Träger für den Antrieb 5, 6 sind nicht näher dargestellt. Sie können auf den Führungsschienen 10 oder im Mauerwerk des Aufzugsschachtes 1 ruhen.According to FIGS. 1 to 3, a support means set 2 fastened at both ends in the upper region of an elevator shaft 1 successively wraps around a counter-load deflection roller 4, a drive pulley 5 of the drive, an input pulley 6 of the drive arranged parallel to the axis of the drive pulley 5, again the traction sheave 5 and the counter pulley 6 of the drive and one attached to a support frame 7 for a car 8 in backpack suspension elevator pulley 9. This is a 2: 1 suspension of counterweight 3 and car 8 and a double wrap the traction sheave 5 of the drive 5, 6 realized. The drive 5, 6 is formed of a non-visible gearless motor, a coaxial with the motor shaft or on a common shaft traction sheave 5, a brake device, not shown, which operates on the engine and / or the traction sheave 5, and the counter-disc 6 , The motor is regulated with the aid of a frequency converter and, in normal operation, also takes over the braking and stopping of the elevator car 8. The counter disk 6 also serves as a deflection disk for the support means set 2 with respect to its guidance in the direction of the car deflection roller 9. The carrier or carriers for the drive 5, 6 are not shown in detail. They can rest on the guide rails 10 or in the masonry of the elevator shaft 1.
In allen Beispielen entfällt eine separater Triebwerksraum, indem der Antrieb 5 , 6 mit der Treibscheibe 5 und der Gegenscheibe 6 im Schachtkopf des Aufzugsschachtes 1 angeordnet ist. Sofern ein Triebwerksraum oberhalb des Schachtkopfes vorhanden ist, kann selbstverständlich der Antrieb 5, 6 auch in diesem in gleicher Weise installiert werden.In all examples, a separate engine room is omitted by the drive 5, 6 is arranged with the traction sheave 5 and the counter disk 6 in the shaft head of the elevator shaft 1. If an engine room above the shaft head is present, of course, the drive 5, 6 are installed in this same way.
Der Fahrkorb 8 ist fest mit dem Traggestell 7 verbunden, das in den Führungsschienen 10 im Aufzugsschacht 1 geführt wird. Die Führungsschienen 10 sind im Beispiel an einer benachbar- ten Wand 12 des Aufzugsschachtes befestigt. Achsparallel wird die Gegenlast 3 an den Führungsschienen 10 im Aufzugsschacht 1 geführt. Dies ist in der Draufsicht dargestellt, wobei zur Verbesserung der in der Draufsicht die Scheiben 5, 6 und Umlenkrollen 4, 9 nicht eingezeichnet sind.The car 8 is fixedly connected to the support frame 7, which is guided in the guide rails 10 in the elevator shaft 1. The guide rails 10 are fastened in the example to an adjacent wall 12 of the elevator shaft. Parallel to the counter-load 3 is guided on the guide rails 10 in the elevator shaft 1. This is shown in plan view, with the discs 5, 6 and pulleys 4, 9 are not shown in the plan view to improve.
In Figur 1 sind die Treibscheibe 5 und die Gegenscheibe 6 in einem vergleichsweise flachen Winkel α zur Waagerechten versetzt angeordnet. Hierdurch wird besonders wenig Raumhöhe im Schachtkopf des Aufzugsschachtes 1 benötigt. Es ist deshalb unkritisch, wenn der Antrieb 5, 6 mit der Gegenscheibe 6, vertikal gesehen, in das lichte Profil des Fahrkorbes 8 hineinragt. Zwar kann der Fahrkorb 8 dadurch nicht bis unmittelbar zur Schachtdecke des Aufzugsschachtes 1 fahren, doch ist dies ohnehin aus sicherheitstechnischen Gründen verboten, um eine zu Reparatur- oder Wartungszwecken zwischen Schachtdecke und Fahrkorbdecke hantierende Person nicht zu gefährden. Die Treibscheibe 5 mit der Gegenscheibe sind zur Fahrkorb-Umlenkrolle 9 achsparallel orientiert, während aus Platzgründen die Achse der Gegenlast-Umlenkscheibe im Winkel von etwa 70° -90° gedreht ist und auf diese Weise nicht über die schmale Gegenlast 3 hinaus steht . Fig. 2 unterscheidet sich gegenüber Fig. 1 dadurch, dass der Antrieb 5, 6 im Winkel α steiler angeordnet ist und die Fahrkorb-Umlenkrolle 9 nicht oberhalb, sondern unterhalb des Fahrkorbes 8 am Traggestell 7 befestigt ist. In Kombination beider Maßnahmen kann der Fahrkorb 8 im Aufzugsschacht analog zu Fig. 1 ebenfalls wieder bis zu einem zulässigen Mindestabstand zwischen Schachtdecke und Fahrkorbdecke hochfahren. Die Fahrkorb-Umlenkrolle 9 ragt in vorteilhafter Weise nicht bis unter das Traggestell 7, wodurch keine Behinderung bei einer Fahrt bis zu den Puffern am Schachtboden auftritt. Aus Platzgründen ist bei diesem Ausführungsbeispiel auch die Fahrkorb- Umlenkrolle 7 analog zur Gegenlast-Umlenkrolle 4 gedreht.In Figure 1, the traction sheave 5 and the counter pulley 6 are arranged offset at a relatively shallow angle α to the horizontal. As a result, particularly little room height in the shaft head of the elevator shaft 1 is required. It is therefore not critical when the drive 5, 6 protrudes with the counter pulley 6, seen vertically, in the clear profile of the elevator car 8. Although the car 8 can not drive directly to the shaft ceiling of the elevator shaft 1, this is anyway prohibited for safety reasons, so as not to jeopardize a person handling the vehicle between the shaft ceiling and the car ceiling for repair or maintenance purposes. The traction sheave 5 with the counter-disc are oriented axially parallel to the cage-pulley 9, while for reasons of space, the axis of the counter-load deflection is rotated at an angle of about 70 ° -90 ° and in this way is not on the narrow counterweight 3 addition. Fig. 2 differs from Fig. 1 in that the drive 5, 6 is arranged steeper at an angle α and the car guide pulley 9 is not mounted above, but below the car 8 on the support frame 7. In combination of the two measures, the car 8 in the elevator shaft can likewise be raised again, as in FIG. 1, up to a permissible minimum distance between the shaft ceiling and the car ceiling. The car deflecting roller 9 does not protrude in an advantageous manner to under the support frame 7, whereby no obstruction occurs when driving up to the buffers on the shaft bottom. For reasons of space, the car deflecting roller 7 is rotated analogously to the counter-load deflection roller 4 in this embodiment.
Gemäß Fig. 3 wird die steile Anordnung von Treibscheibe 5 und Gegenscheibe 6 (Winkel α entsprechend Fig. 2) beibehalten, außerdem jedoch die Fahrkorb-Umlenkrolle 9 oben am Traggestell 7 entsprechend Fig. 1 befestigt. Anders als nach Fig. 1 und Fig. 2, sind jedoch zwei Paar Führungsschienen vorgesehen, nämlich ein Paar Führungsschienen 10 für das Traggestell 7 und ein Paar Führungsschienen 11 für eine im Querschnitt etwa quadratische Gegenlast 3. Das Traggestell 7 ist in den Raum zwischen den Führungsschienen 10, 11 hineingeschoben, wodurch der Abstand zwischen der benachbarten Wand 12 des Aufzugsschachtes 1 und der Rückwand des Fahrkorbes 8 bis auf den Raum für die Gegenlast 3 verringert werden kann. Die Anordnung nach Fig. 3 eignet sich folglich besonders für sehr schmale Aufzugsschachte 1. According to Fig. 3, the steep arrangement of traction sheave 5 and counter-disc 6 (angle α corresponding to FIG. 2) is maintained, but also the car-deflecting roller 9 is fixed to the top of the support frame 7 as shown in FIG. Unlike in Fig. 1 and Fig. 2, however, two pairs of guide rails are provided, namely a pair of guide rails 10 for the support frame 7 and a pair of guide rails 11 for a cross-sectionally approximately square counter load 3. The support frame 7 is in the space between the Guide rails 10, 11 pushed in, whereby the distance between the adjacent wall 12 of the elevator shaft 1 and the rear wall of the car 8 can be reduced to the space for the counterweight 3. The arrangement according to FIG. 3 is consequently particularly suitable for very narrow elevator shafts 1.
