Description

Die vorliegende Erfindung bezieht sich auf eine Aufzugsanlage und auf ein Verfahren zur Anordnung einer Antriebsmaschine einer Aufzugsanlage gemäss der Definition der Patentansprüche.The present invention relates to an elevator installation and to a method for the arrangement of a drive machine of an elevator installation according to the definition of the claims.

Eine Aufzugsanlage, bei der eine Antriebsmaschine eine Kabine und ein Gegengewicht über ein Antriebsseil verfährt und welche Aufzugsanlage keinen separaten Maschinenraum benötigt, ist aus dem Gebrauchsmuster JP-50297/1992 bekannt. Als Führung für Kabine und Gegengewicht dienen zwei vertikale Säulen in Form von selbsttragenden U-Profilen. Die Säulen sind an ihrem oberen Ende mit einer horizontalen Traverse abgeschlossen, auf der die Antriebsmaschine montiert ist. Durch das Wegfallen des Maschinenraums weist diese Aufzugsanlage den Vorteil geringerer Gestehungskosten auf.An elevator installation in which a drive machine moves a car and a counterweight via a drive cable and which elevator installation does not require a separate engine room is known from the utility model JP-50297/1992 known. As a guide for cabin and counterweight serve two vertical columns in the form of self-supporting U-profiles. The columns are terminated at their upper end with a horizontal crosshead on which the prime mover is mounted. By eliminating the engine room, this elevator system has the advantage of lower production costs.

Das Patent EP-1045811 zeigt eine Aufzugsanlage, bei der eine die Antriebsmaschine tragende Traverse an insgesamt vier Führungen für Kabine und Gegengewicht befestigt ist. Auf diese Weise wird die gesamte vertikale Gewichtskraft von Antriebsmaschine, Kabine und Gegengewicht ausschliesslich über diese Führungen auf den Schachtboden geleitet und dort abgestützt. Dabei finden preiswerte, konventionelle Führungen Verwendung. Hinzu kommt der weitere Vorteil, dass die Antriebsmaschine keine Biegemomente auf die tragenden Führungen ausübt, da durch diese Anordnung und Befestigung nur vertikale Kräfte auf die Führungen wirken. Nachteilig an dieser Aufzugsanlage ist die Einschränkung der Anordnung der Antriebsmaschine auf den seitlichen Schachtbereich, in dem die Führungen verlaufen.The patent EP-1045811 shows an elevator system in which a traction machine carrying the traverse is attached to a total of four guides for cabin and counterweight. In this way, the entire vertical weight of the prime mover, cab and counterweight is guided exclusively on these guides on the shaft bottom and supported there. Here are inexpensive, conventional guides use. In addition, there is the further advantage that the prime mover exerts no bending moments on the supporting guides, since only vertical forces act on the guides by this arrangement and attachment. A disadvantage of this elevator system is the restriction of the arrangement of the drive machine on the lateral shaft area in which run the guides.

US2002/0070080 zeigt eine weitere Aufzugsanlage, bei der eine die Antriebsmaschine tragende Traverse an Gegengewichtsführungen und an eine Kabinenführung befestigt ist und als gesamtes, mittels einer Quertraverse, zu einer zweiten Kabinenführung verbunden ist. Auf diese Weise werden Kräfte von Kabinen- und Gegengewichtsführungsschienen aufgenommen und direkt in einen Schachtboden eingeleitet. US2002 / 0070080 shows a further elevator system, in which a traction machine carrying the crossmember is attached to counterweight guides and to a cabin guide and is connected as a whole, by means of a crossbeam, to a second cabin guide. In this way, forces are absorbed by cabin and counterweight guide rails and introduced directly into a shaft bottom.

Aufgabe der vorliegenden Erfindung ist es, eine Aufzugsanlage mit flexibler Anordnung der Antriebsmaschine bereit zustellen. Die Antriebsmaschine soll weitgehend im gesamten Schachtbereich oberhalb von Kabine und Gegengewicht frei wählbar anzuordnen sein. Die Antriebsmaschine soll platzsparend angeordnet und von kleinen Abmessungen sein.The object of the present invention is to provide an elevator installation with a flexible arrangement of the drive machine. The prime mover is to be arranged freely selectable largely throughout the shaft area above the car and counterweight. The drive machine should be arranged to save space and be of small dimensions.

Diese Aufgabe wird durch die Erfindung gemäss der Definition der Patentansprüche gelöst.This object is achieved by the invention according to the definition of the claims.

Die Erfindung betrifft eine Aufzugsanlage mit Kabine und Gegengewicht und einem Schacht. Sie weist eine auf einer Traverse montierte Antriebsmaschine auf. Die Traverse ist über zwei Endbereiche an je einer Gegengewichtsführung befestigt und sie ist mit einem mittleren Bereich an mindestens einer Kabinenführung befestigt.The invention relates to an elevator installation with cabin and counterweight and a shaft. It has a drive unit mounted on a traverse. The traverse is attached via two end regions to a respective counterweight guide and it is fastened with a central region on at least one cabin guide.

Die zwei Gegengewichtsführungen und eine Kabinenführung spannen im Schacht ein weitgehend horizontales Dreieck auf. Die Antriebsmaschine ist von länglicher und kompakter Form. Vorteilhafterweise weist die Antriebsmaschine zwei Treibscheiben auf, welche symmetrisch, links und rechts von einer horizontalen Verbindenden der Kabinenführungen angeordnet sind.The two counterweight guides and a cabin guide span a largely horizontal triangle in the shaft. The prime mover is of elongated and compact shape. Advantageously, the prime mover on two traction sheaves, which are arranged symmetrically, left and right of a horizontal connecting ends of the cabin guides.

Durch diese im Dreieck symmetrische Anordnung der Führungen werden Gewichtskräfte der Antriebsmaschine sowie beim Betrieb der Antriebsmaschine auftretende Biegemomente effektiv aufgenommen und über die Traverse und die Führungen in den Schachtboden geleitet. Die Antriebsmaschine lässt sich auf der Fläche dieses Dreiecks frei wählbar entweder weitgehend oberhalb des Gegengewichts und/oder weitgehend oberhalb der Kabine anordnen. Diese Flexibilität hinsichtlich der Anordnung der Antriebsmaschine wird durch Grösse und Form der Traverse und/oder die Anzahl der verwendeten Umlenkrollen und/oder die Art des verwendeten Treibmittels ermöglicht.As a result of this arrangement of the guides, which is symmetrical in the triangle, weight forces of the drive machine and bending moments occurring during operation of the drive machine are effectively absorbed and directed into the shaft bottom via the crossbar and the guides. The prime mover can be freely arranged on the surface of this triangle either largely above the counterweight and / or largely above the cabin. This flexibility with respect to the arrangement of the drive machine is made possible by the size and shape of the traverse and / or the number of pulleys used and / or the type of propellant used.

Im Folgenden wird die Erfindung anhand beispielhafter Ausführungsformen gemäss der Fig. 1 bis 4 im Detail erläutert. Hierbei zeigen:

Fig. 1 zeigt eine schematische Darstellung der Dreiecks-Anordnung von Führungen 5, 5', 9, 9' einer Aufzugsanlage. Die Aufzugsanlage ist bspw. in einem weitgehend vertikalen Schacht 10 angeordnet. Der Schacht 10 weist bspw. einen rechteckigen Querschnitt mit vier Wänden auf. Im Schacht sind weitgehend vertikal angeordnete Kabinenführungen 5, 5' und Gegengewichtsführungen 9, 9' befestigt. Zwei Kabinenführungen führen eine Kabine 11 und zwei Gegengewichtsführungen führen ein Gegengewicht 12. Die Führungen sind an nächstliegenden Wänden befestigt. Die zwei Gegengewichtsführungen 9, 9' und eine erste Kabinenführung 5 sind an einer ersten Wand befestigt. Die zweite Kabinenführung 5' ist an einer zweiten Wand befestigt. Die zweite Wand liegt der ersten Wand gegenüber. Die erste Kabinenführung 5 ist weitgehend mittig zwischen den zwei Gegengewichtsführungen 9, 9' angeordnet. Die Führungen sind aus bewährten Materialien wie Stahl. Die Befestigung der Führungen an den Wänden erfolgt bspw. über Schraubverbindungen. Bei Kenntnis der vorliegenden Erfindung lassen sich auch andere Schachtgeometrien mit quadratischem-, ovalem- bzw. rundem Querschnitt realisieren. Fig. 1 shows a schematic representation of the triangular arrangement of guides 5, 5 ', 9, 9' of an elevator system. The elevator installation is, for example, arranged in a largely vertical shaft 10. The shaft 10 has, for example, a rectangular cross section with four walls. In the shaft largely vertically arranged cabin guides 5, 5 'and counterweight guides 9, 9' are attached. Two car guides carry a car 11 and two counterweight guides carry a counterweight 12. The guides are attached to nearest walls. The two counterweight guides 9, 9 'and a first cabin guide 5 are fixed to a first wall. The second cabin guide 5 'is attached to a second wall. The second wall is opposite the first wall. The first cabin guide 5 is arranged substantially centrally between the two counterweight guides 9, 9 '. The guides are made of proven materials such as steel. The attachment of the guides on the walls takes place, for example, via screw. With knowledge of the present invention, other shaft geometries with square, oval or round cross-section can be realized.

Die zwei Gegengewichtsführungen 9, 9' und jeweils eine der beiden Kabirienführungen 5, 5' spannen im Schacht 10 ein weitgehend horizontales Dreieck T auf. Die horizontale Verbindende zwischen den beiden Gegengewichtsführungen bildet eine erste Seite des Dreiecks T. Die horizontalen Verbindenden zwischen einer Gegengewichtsführung und einer Kabinenführung bilden zweite- und dritte Seiten des Dreiecks T. Vorteilhafterweise ist die horizontale Verbindende der Gegengewichtsführungen länger als eine horizontale Verbindende der Kabinenführungen, so dass ein Dreieck T bestehend aus Führungen 9, 9', 5 der ersten Wand einen der horizontalen Verbindenden der Gegengewichtsführungen 9, 9' gegenüberliegenden stumpfen Winkel auf weist bzw. dass ein Dreieck T bestehend aus den Gegengewichtsführungen 9, 9' der ersten Wand und einer Kabinenführung 5' der zweiten Wand einen der horizontalen Verbindenden der Gegengewichtsführungen 9, 9' gegenüberliegenden spitzen Winkel aufweist. Vorteilhafterweise schneidet die horizontale Verbindende der Kabinenführungen die horizontale Verbindende der Gegengewichtsführungen weitgehend mittig, so dass das Dreieck T weitgehend gleichschenklig ist.The two counterweight guides 9, 9 'and one of the two Kabirienführungen 5, 5' span in the shaft 10 a substantially horizontal triangle T. The horizontal connecting end between the two counterweight guides forms a first side of the triangle T. The horizontal connecting ends between a counterweight guide and a car guide form second and third sides of the triangle T. Advantageously, the horizontal connecting end of the counterweight guides is longer than a horizontal connecting end of the car guides that a triangle T consisting of guides 9, 9 ', 5 of the first wall has one of the horizontal connecting ends of the counterweight guides 9, 9' opposite obtuse angle or that a triangle T consisting of the counterweight guides 9, 9 'of the first wall and a Cabin guide 5 'of the second wall has one of the horizontal connecting ends of the counterweight guides 9, 9' opposite acute angle. Advantageously, the horizontal connecting end of the car guides cuts the horizontal connecting end of the counterweight guides largely centrally, so that the triangle T is largely isosceles.

Die Fig. 2 bis 4 zeigen eine Antriebsmaschine 1, 2, 3, 3', 4, 40 mit zwei Treibscheiben 3, 3' auf. Vorteilhafterweise sind die Treibscheiben 3, 3' über eine Welle 4 mit einem Motor 1 und einer Bremse 2 wirkverbunden. Vorteilhafterweise sind Motor und Bremse an zwei Endbereichen der Welle angeordnet und die Treibscheiben sind zwischen Motor und Bremse in einem mittleren Bereich der Welle angeordnet. Eine Steuerung und/oder ein Umformer der Aufzugsanlage ist in einem Schaltkasten 6 vorteilhafterweise an einer Wand im Schacht 10 angeordnet. In den Ausführungsformen gemäss Fig. 2 bis 4 ist die Antriebsmaschine getriebelos und von länglicher Form, d.h. in einer Ebene senkrecht zur Achse der Welle 4 gesehen, ist der Durchmesser der Antriebsmaschine geringer als die Länge der Antriebsmaschine.The Fig. 2 to 4 show an engine 1, 2, 3, 3 ', 4, 40 with two traction sheaves 3, 3'.

Advantageously, the motor and brake are arranged on two end regions of the shaft and the traction sheaves are arranged between the motor and the brake in a central region of the shaft. A controller and / or a converter of the elevator installation is advantageously arranged in a control box 6 on a wall in the shaft 10. In the embodiments according to Fig. 2 to 4 is the drive machine gearless and elongated shape, ie seen in a plane perpendicular to the axis of the shaft 4, the diameter of the drive machine is less than the length of the drive machine.

Vorteilhafterweise sind zwei Treibscheiben 3, 3' symmetrisch, links und rechts von einer horizontalen Verbindenden der Kabinenführungen 5, 5' angeordnet. Vorteilhafterweise sind die Treibscheiben 3, 3' im Durchmesser kleiner als das Motorgehäuse und/oder das Bremsgehäüse.Advantageously, two traction sheaves 3, 3 'symmetrically, left and right of a horizontal connecting ends of the cabin guides 5, 5' are arranged. advantageously, are the traction sheaves 3, 3 'in diameter smaller than the motor housing and / or the brake housing.

Die weitgehend horizontal im Schacht angeordnete Antriebsmaschine verfährt die über mindestens ein Treibmittel 19, 19' miteinander verbundene Kabine und Gegengewicht im Schacht. Das Treibmittel weisen zwei Enden 18, 18' auf. Das Treibmittel ist ein Seil und/oder ein Riemen von beliebiger Natur. Die lasttragenden Bereiche des Treibmittels bestehen aus Metall wie Stahl und/oder Kunststoff wie Aramid. Das Seil kann ein Einzel- oder Mehrfachseil sein, auch kann das Seil eine aussenseitige Schutzhülle aus Kunststoff aufweisen. Der Riemen kann flach und aussenseitig unstrukturiert glatt oder bspw. in Keilrippen bzw. Zahnriemen strukturiert sein. Vorteilhafterweise werden zwei Treibmittel verwendet.The largely horizontally arranged in the shaft drive machine moves the at least one propellant 19, 19 'interconnected cabin and counterweight in the shaft. The propellant has two ends 18, 18 '. The propellant is a rope and / or a belt of any nature. The load bearing areas of the propellant are made of metal such as steel and / or plastic such as aramid. The rope may be a single or multiple rope, also the rope may have an outer protective plastic cover. The belt can be flat and structurally unstructured on the outside or structured, for example, in V-ribs or toothed belts. Advantageously, two blowing agents are used.

Ein jedes der Enden des Treibmittels ist entweder an einer Schachtwand/Schachtdecke und/oder an einer Kabinenführung und/oder an einer Gegengewichtsführung und/oder an einer Traverse 8 und/oder an der Kabine und/oder am Gegengewicht fixiert. Vorteilhafterweise werden die Enden des Treibmittels über elastische Zwischenelemente zum Dämpfen von Körperschall fixiert. Die Zwischenelemente sind bspw. Federelemente, die die Übertragung von als unangenehm wahrgenommenen Schwingungen vom Treibmittel in die Schachtwand/Schachtdecke und/oder Kabinenführung und/oder Gegengewichtsführung und/oder Traverse und/oder Kabine und/oder Gegengewicht verhindern. Mehrere beispielhafte Ausführungsformen von Fixierungen der Enden des Treibmittels werden unterschieden:
