Description

Liftkabine mit Wartungsfenster Lift cabin with maintenance window
[0001] Diese Erfindung betrifft eine Liftkabine mit einem besonderen Wartungsfenster. Die Lifte müssen regelmässig kontrolliert und gewartet werden. Dabei müssen im Wesentlichen folgende Elemente geprüft und gewartet werden: Die Schienenbefestigungen, die Tragseile, die Tragseilbefestigungen, die Rillen der Treibscheiben oder des Treibrohres eines Traktionsantriebes, die Umlenkrollen, die Endschalter, das Fangbremsseil und seine Befestigung, und die Führungen des Fahrwerks bzw. der Kabine sowie des Gegengewichtes. Diese Arbeiten werden herkömmlich bei den meisten Liften durchgeführt, indem der Liftmonteur auf dem Dach der Liftkabine steht. Dieses Dach muss nach Vorschrift gebaut sein und mit einer Brüstung versehen sein. Zum Kontrollieren und Warten wird die Liftkabine langsam oder in langsamen Etappen über den ganzen Fahrweg verfahren, sodass der Liftmonteur durch Überprüfen von Auge alle nötigen Elemente sieht und mit seinen Händen Zugang zu allen Elementen hat, an denen er Wartungsarbeiten durchführen muss, etwa Schrauben nachziehen, drehende Teile schmieren, mechanische Spannungen überprüfen, die Funktion von Endschaltern testen etc. Als weitere Wartungsmöglichkeit ist es bei einigen Liften möglich, das Kabinendach oder eine Dachluke im Kabinendach in die Kabine hinunterzuschwenken, wonach ein Arbeitspodest aus dem dann lotrecht hängenden Kabinendach abgeklappt werden kann. Der Liftmonteur kann dann auf dieses Podest steigen, entweder über eine Leiter von der Liftkabine aus oder vom Stockwerkboden durch die offene Liftkabine. In einer anderen Ausführung kann er vom nächsthöheren Stockwerkboden aus auf das Kabinendach gelangen und von dort aufs mit einer Leiter auf dieses Podest hinuntersteigen. Wenn der Liftmonteur auf diesem Arbeitspodest steht, so ragt er genügend weit oben aus der Liftkabine heraus, dass er die nötigen Arbeiten im Liftschacht durchführen kann. In noch weiteren Ausführungen sind die Kabinenwände mit Fenstern ausgerüstet, deren Fensterflügel gegen das Kabineninnere hin aufgeschwenkt werden können, oder es sind Schiebefenster vorgesehen, sodass der Zugang zum Liftschacht auf der Seite dieses Fensters freigegeben ist. Eine solche Lösung geht etwa aus der WO01/79104, aus der JP 10-231074 oder der EP 1 031 528 B1 hervor. Dort ist eine Zugangsöffnung offenbart, welche an jener Seitenwand der Fahrzelle vorgesehen ist, welche der Fördervorrichtung des Liftes zugewandt ist, sodass die Fördereinrichtung für die Wartung durch diese Zugangsöffnung vom Innern der Fahrzelle aus zugänglich ist. Allerdings sind bei den dort vorgestellten Lösungen durchwegs nicht sämtliche Wartungsarbeiten aus dem Kabineninnem heraus durchführbar. Die Antriebseinheit liegt bei WO01/79104 und auch bei JP 10- 231074 oberhalb der Kabine, die Führungsschienen für die Kabine selbst liegen bei EP 1 031 528 B1 ausserhalb des von der Kabine aus zugänglichen Bereichs, nämlich auf solchen Seitenflächen der Kabine, die nicht öffnenbar sind. Die Befestigung und der Zustand dieser Führungsschienen sind deshalb nicht von der Kabine aus überprüfbar. Oftmals sind auch die Seilführungen und ihre Befestigungen so angelegt, dass sie nicht von der Kabine aus überprüfbar sind.This invention relates to a lift cab with a special maintenance window. The lifts must be checked and maintained regularly. Essentially, the following elements must be checked and maintained: The rail fasteners, the suspension cables, the suspension cable fixings, the grooves of the traction sheaves or the traction drive tube, the pulleys, the limit switches, the safety brake cable and its attachment, and the guides of the chassis or the Cabin as well as the counterweight. This work is traditionally carried out on most lifts, with the lift mechanic standing on the roof of the lift cabin. This roof must be built according to regulations and be provided with a parapet. To control and maintain the elevator car is moved slowly or in slow stages over the entire track, so that the lift fitter sees by eye inspection all the necessary elements and has access with his hands to all elements on which he must perform maintenance, such as tightening screws, Lubricate rotating parts, check mechanical tension, test the function of limit switches, etc. As a further maintenance option, it is possible for some lifts to lower the car roof or roof hatch in the cabin roof, after which a work platform can be folded out of the then vertically suspended canopy. The lift mechanic can then climb onto this pedestal, either via a ladder from the lift cabin or from Floor through the open elevator cabin. In another embodiment, he can get from the next higher floor of the floor on the cabin roof and from there rise with a ladder on this pedestal. When the lift mechanic is standing on this work platform, he protrudes from the elevator cabin well enough that he can carry out the necessary work in the elevator shaft. In still further embodiments, the cabin walls are equipped with windows whose casement can be pivoted against the cabin interior, or sliding windows are provided so that the access to the elevator shaft is released on the side of this window. Such a solution can be found, for example, in WO 01/79104, JP 10-231074 or EP 1 031 528 B1. There, an access opening is disclosed, which is provided on that side wall of the car, which faces the conveyor of the lift, so that the conveyor for maintenance through this access opening from the interior of the car is accessible. However, not all maintenance work from inside the cabin is consistently feasible in the solutions presented there. The drive unit is located above the car in WO01 / 79104 and also in JP 10-231074, the guide rails for the car itself are outside the range accessible from the cab, namely on such side surfaces of the car, which can not be opened in EP 1 031 528 B1 are. The attachment and the condition of these guide rails are therefore not verifiable from the cabin. Often, the cable guides and their fortifications are designed so that they can not be checked from the cab.

Liftkabine befinden und somit durch eine geöffnete Kabinen-Seitenwand zugänglich sind. In diesem Fall aber sind auch Vorschriften zu erfüllen. So muss nämlich der Abstand von der Brüstung, bis zu welcher hin der Monteur stehen kann, bis zu den Seilen oder anderen beweglichen Teilen der Fördervorrichtung mindestens 10 cm betragen.Lift cabin are located and thus accessible through an open cabin side wall. In this case, however, regulations must also be met. For example, the distance from the parapet, up to which the installer can stand, to the ropes or other moving parts of the conveyor must be at least 10 cm.
[0003] Diese Aufgabe wird gelöst von einer Liftkabine mit Wartungsfenster für einen Lift, bei dem sämtliche zu wartende und zu prüfende Elemente gegenüber einer einzigen Seite der Liftkabine angeordnet sind, und die sich dadurch auszeichnet, dass auf dieser Seite ein mehr als 85cm über dem Kabinenboden der Kabinenwand angeordnetes Teil nach dem Kabineninnern hin wegnehmbar ausgeführt ist, wobei dieses Teil wenigstens 95cm hoch ist und nach Entfernung auf dem Kabinenboden stehend zur Bildung einer Brüstung an diese Kabinenwand anlehnbar ist, wobei mindestens ein Distanzhalter zwischen diesem wegnehmbaren Teil und dem unteren Teil der Kabinenwand vorhanden ist, sodass die Distanz von der Inneren, der Kabine zugewandten Seite des am Boden abgestellten Seitenwandteils bis zu den relativ zur fahrenden Liftkabine bewegenden Elementen des Liftantriebs mindestens 10cm beträgt.This object is achieved by a lift cabin with maintenance window for a lift in which all the elements to be serviced and tested are arranged opposite a single side of the elevator cabin, and which is characterized in that on this side a part arranged more than 85 cm above the cabin floor of the cabin wall is designed to be removable towards the inside of the cabin, this part is at least 95 cm high and, after being removed from the cabin floor, can be leaned against this cabin wall to form a parapet, at least one spacer being provided between this removable part and the lower part of the cabin wall, so that the distance from the inside, the cabin facing side of the parked at the bottom side wall part to the moving relative to the moving elevator car elements of the lift drive is at least 10cm.
[0004] In den Zeichnungen wir diese Liftkabine dargestellt und ihr Wartungsfenster wird anhand dieser Zeichnungen beschrieben und seine Funktion wird erläutert.In the drawings, this lift cabin is shown and its maintenance window will be described with reference to these drawings and its function will be explained.

[0005] In Figur 1 ist ein Blick in die geöffnete Liftkabine gewährt, von der Zutrittstüre aus gesehen. Hier ist die Liftkabine in betriebsbereitem Zustand gezeigt. Die Seitenwände sind durch Panelen 3,6,15 gebildet, welche zum Beispiel von seitlichen Führungsleisten 14 gehalten sind, die ihrerseits durch Steck- oder Schraubverbindungen mit dem Rahmen der Liftkabine verbunden sind. Eine Sicherungsleiste 16 kann zum Beispiel oben längs des Kabinendaches horizontal verlaufend angeordnet sein. Diese ist mit einem Schliessmechanismus ausgerüstet, welcher mit einem Drei- oder Vierkantschlüssel geöffnet werden kann, indem dieser beim Loch 17 eingesteckt und dann gedreht wird. Auf der hinteren Kabinenseite ist hier eine zweite Lifttüre 18 aus zwei horizontal nach aussen verschiebbaren Türenteilen angeordnet. Wie man erkennt, ist die Seitenwand links unterteilt in einen oberen Seitenwandteil 3 und einen unteren Seitenwandteil 6. Zwischen diesen Teilen ist eine Querstrebe 19 angeordnet, welche einen Handlauf 5 trägt, hier in Form eines Chromstahlrohres, das einige Zentimeter von der Seitenwand beabstandet ist. Anstelle eines Rohres kann auch eine Leiste vorgesehen werden, die hintergreifbar ist. Das hier obere Seitenwandtei! 3 ist als Besonderheit mit wenigen Handgriffen von der Liftkabinenseite entfernbar. Hierzu wird zunächst die Sicherungsleiste 16 entfernt, indem der Schliessmechanismus mittels eines Schlüssels gelöst wird. Nach Entfernen der Sicherungsleiste 16 können die seitlichen Halteleisten 14 entfernt werden. Diese sind zum Beispiel unten in Profilleisten gesteckt und oben durch eine Steck- oder Schraubverbindung mit dem Rahmen der Liftkabine verbunden. Nach Entfernen dieser Halteleisten 14 können diese für eine Zwischenlagerung zum Beispiel an der gegenüberliegenden Kabinenwand angelehnt werden. Nun aber sind die seitlichen Ränder des oberen Seitenwandteils 3 freigelegt. Dieses Seitenwandteil 3 kann nun mit den Händen an den seitlichen Rändern ergriffen werden und aus seinem unteren Halteprofil, welches längs des oberen Randes des unteren Seitenwandteils 6 verläuft, herausgehoben werden und hernach auf dem Kabinenboden 1 abgestellt werden.In Figure 1, a view is granted in the open elevator cabin, seen from the entrance door. Here the lift cabin is shown ready for use. The side walls are formed by panels 3, 6, 15, which are held, for example, by lateral guide rails 14, which in turn are connected to the frame of the elevator cabin by plug-in or screw connections. A fuse strip 16 may for example be arranged horizontally along the top of the cabin roof. This is equipped with a closing mechanism, which can be opened with a three or square wrench by this is inserted at the hole 17 and then rotated. On the rear cabin side, a second lift door 18 is arranged here, consisting of two horizontally outwardly displaceable door parts. As can be seen, the side wall is divided left into an upper side wall part 3 and a lower side wall part 6. Between these parts, a transverse strut 19 is arranged, which carries a handrail 5, here in the form of a chromium steel tube, which is a few centimeters from the side wall. Instead of a pipe, a strip can be provided, which can be engaged behind. The upper side wall part! 3 is a special feature with a few simple steps from the lift cabin side removable. For this purpose, the fuse strip 16 is first removed, by loosening the closing mechanism by means of a key. After removal of the fuse strip 16, the lateral retaining strips 14 can be removed. These are, for example, stuck in the bottom of moldings and connected at the top by a plug or screw connection to the frame of the elevator car. After removal of these retaining strips 14, these can be ajar for temporary storage, for example, on the opposite cabin wall. But now the lateral edges of the upper side wall part 3 are exposed. This side wall part 3 can now be grasped by the hands at the lateral edges and be lifted out of its lower holding profile, which runs along the upper edge of the lower side wall part 6, and afterwards parked on the cabin floor 1.
[0006] Diese Situation ist in Figur 2 gezeigt. Das demontierte Seitenwandtei! 3 ist hier auf dem Liftkabinenboden 1 abgestellt und ist an den Handlauf 5 angelehnt. Somit ist durch das oberhalb des abgestellten Seitenteils 3 geschaffene Wartungsfenster der Blick auf alle Elemente des Liftantriebes, die gewartet und kontrolliert werden müssen, freigegeben und diese Elemente sind auch manuell zugänglich. Das demontierte Seitenwandteil 3 schliesst in Montagelage einen hier nicht gezeigten Kontaktschalter, der aussen an der Liftkabine montiert ist. Sobald das Seitenwandteil 3 entfernt ist, kann die Liftkabine nicht mehr gefahren werden. Wenn das Seitenwandteil 3, das vorzugsweise 100cm hoch ist, auf dem Boden 1 der Kabine abgestellt und am Handlauf 5 angelehnt ist, so bildet es mit seinem oberen Rand 4 eine vorschriftsgemässe Brüstung für den Liftmonteur, der nun durch das geschaffene offene Wartungsfenster an den Elementen des Liftantriebes seine Arbeiten durchführen kann. Damit die Liftkabine während dieser Arbeiten und noch vielmehr zum Zweck der Durchführung dieser Arbeiten mit offenem Wartungsfenster fahrbar ist, muss stets sichergestellt sein, dass ein vorgeschriebener Abstand zwischen der Brüstung und den nächstliegenden sich relativ zur Liftkabine bewegenden Teilen von mindestens 10cm besteht. Durch das Abstellen des demontierten Seitenwandteils 3 und Abstellen desselben vor dem unteren Seitenwandteil 6 und Anlehnen an den Handlauf 5 wirkt derselbe als Distanzhalter. Die Liftantriebe werden ja möglichst schmal ausgeführt, um Platz im Liftschacht einzusparen. Entsprechend nah an der Liftkabine verlaufen die Trag- und Antriebsseile 7 sowie die Führungsschienen 8 für die Liftkabine und das Gegengewicht. Durch das nach innen in das Kabineninnere versetzte Abstellen des herausgenommenen Seitenwandteils 3 kann dieser geforderte Abstand von 10cm leicht eingehalten werden, wie in der Figur sichtbar.This situation is shown in FIG. The dismantled Seitenwandtei! 3 is parked here on the elevator car floor 1 and is based on the handrail 5. Thus, through the created above the parked side panel 3 maintenance window, the view of all elements of the lift drive, which must be maintained and checked, released and these elements are also accessible manually. The dismantled side wall part 3 closes in the mounting position a contact switch, not shown here, which is mounted outside of the elevator car. Once the side wall part 3 is removed, the elevator car can not be driven. If the side wall portion 3, which is preferably 100cm high, placed on the floor 1 of the cabin and ajar against the handrail 5, so it forms with its upper edge 4 a proper parapet for the lift fitter, who now through the created open maintenance window on the elements the lift drive can carry out its work. In order for the elevator car to be movable during this work and even more so for the purpose of carrying out this work with an open maintenance window, it must always be ensured that a prescribed distance exists between the parapet and the nearest parts moving at least 10 cm relative to the lift cabin. By turning off the dismantled side wall part 3 and parking it in front of the lower side wall part 6 and leaning against the handrail 5, the same acts as a spacer. The lift drives are designed as narrow as possible to save space in the elevator shaft. Corresponding to the lift cabin, the carrying and drive cables 7 and the guide rails 8 for the elevator car and the counterweight. As a result of the parking of the removed side wall part 3, which is offset inwards into the cabin interior, this required distance of 10 cm can easily be maintained, as can be seen in the figure.
[0007] In einem zweiten Schritt wird nun dieses abgestellte Seitenwandteil 3 vor einem Umfallen gesichert und gleichzeitig wird damit erreicht, dass die Liftkabine wieder gefahren werden kann. Das wird anhand der Figur 3 erläutert, wo man das obere Seitenwandteil 3 auf dem Liftkabinenboden vor dem unteren Seitenwandteil 6 dargestellt sieht, und zwar von der Seite her gesehen. An der Aussenseite der Liftkabine ist ein Kabelhalter 9 montiert, und von diesem Kabelhalter 9 aus führt ein zweipoliges Kabel 11 zu einem endseitigen Stecker 12. Dieser Stecker 12 kann wie hier gezeigt an einer Buchse 13 eingesteckt werden, die auf der Rückseite des herausnehmbaren oberen Seitenwandteils 3 montiert ist. In der Buchse 13 werden die beiden Pole des Steckers 12 miteinander elektrisch verbunden. Sobald also der Stecker 12 in die Buchse 13 eingesteckt wird, wird ein Stromkreis geschlossen, sodass die Liftkabine fahrbar ist. Diese Steckverbindung sichert einerseits das herausnehmbare Seitenwandteil 3 vor einem Umfallen in der Liftkabine, und andrerseits schliesst sie einen Stromkreis, sodass die Liftkabine fahrbar ist. Somit ist die Liftkabine nur dann fahrbar, wenn das demontierte Seitenwandteil 3 korrekt vor dem unteren Seitenwandteil 6 abgestellt ist und somit erstens eine Brüstung 4 mit dem geforderten Minimalabstand zu den beweglichen Teilen, etwa den vorbeilaufenden Seilen 7 gebildet ist, und zweitens der Stromkreis zum Fahren der Liftkabine geschlossen ist. Dieser Kontakt aber lässt sich nur mit korrekt abgestelltem Seitenwandteil 3 schliessen, denn nur dann lässt sich der Stecher 12 in die Buchse 13 einstecken und der Stromkreis schliessen.In a second step, this parked side wall part 3 is now secured from falling over and at the same time is achieved so that the elevator car can be driven again. This will be explained with reference to FIG. 3, where the upper side wall part 3 is seen on the elevator car floor in front of the lower side wall part 6, viewed from the side. On the outside of the elevator car, a cable holder 9 is mounted, and from this cable holder 9 leads from a two-pole cable 11 to an end-side plug 12. This plug 12 can be inserted as shown here on a socket 13, on the back of the removable upper side wall portion 3 is mounted. In the socket 13, the two poles of the plug 12 are electrically connected to each other. As soon as the plug 12 is plugged into the socket 13, a circuit is closed, so that the elevator car is mobile. This connector secures on the one hand the removable side wall part 3 from falling over in the elevator car, and on the other hand, it closes a circuit, so that the elevator car is mobile. Thus, the elevator car is mobile only when the dismantled side wall part 3 is correctly parked in front of the lower side wall part 6 and thus, first, a parapet 4 with the required minimum distance to the moving parts, such as the passing cables 7 is formed, and secondly the circuit for driving the elevator car is closed. However, this contact can be closed only with correctly turned off side wall part 3, because only then can the engraver 12 plug into the socket 13 and close the circuit.
[0008] Anstelle eines Handlaufes 5, der hier als Distanzhalter für das abgestellte Seitenwandteil 3 dient, kann auch ein Bügel dienen, welcher auf der Rückseite des Seitenwandteils 3 montiert ist. Bei Liften, in denen aus Platzgründen kein Handlauf vorgesehen ist, wird diese Lösung angewendet. Sie ist in Figur 4 dargestellt. An einer Halterung 21 , die an der Rückseite des Seitenwandteils 3 montiert ist, ist eine Bügel 19 schwenkbar gelagert. In der abgeschwenkten Lage hängt er einfach am Schwenklager und trägt nach hinten auf der Rückseite des Seitenwandteils 3 nur wenig auf. Nachdem das Seitenwandteil 3 nach Demontage auf den Kabinenboden 1 abgestellt wird, kann der Liftmonteur den Bügel 19 nach oben schwenken und mit seinem endseitigen Profil 20 über den oberen Rand des unteren Seitenwandteils 6 stülpen. Damit ist ebenfalls die Einhaltung des geforderten Abstandes von mindestens 10cm zu den beweglichen Teilen sichergestellt, wie eingezeichnet, und das Seitenwandteil 3 kann nicht umfallen. Dann wird als Nächstes noch der Stromkreis geschlossen, wie schon zu Figur 3 beschrieben.Instead of a handrail 5, which serves as a spacer for the parked side wall part 3, also serve a bracket, which is mounted on the back of the side wall part 3. For lifts where there is no handrail for space reasons, this solution is used. It is shown in FIG. On a bracket 21 which is mounted on the back of the side wall part 3, a bracket 19 is pivotally mounted. In the downhill position he simply hangs on the pivot bearing and contributes to the rear on the back of the side wall part 3 little. After the side wall part 3 is turned off after disassembly on the cabin floor 1, the lift mechanic can swing the bracket 19 upwards and put it with its end-side profile 20 over the upper edge of the lower side wall part 6. This also ensures compliance with the required distance of at least 10 cm to the moving parts, as shown, and the side wall part 3 can not fall over. Then next the circuit is closed, as already described for Figure 3.
[0009] Das wegnehmbare Seitenwandteil 3 kann ein Spiegelglas sein, welches in eine Profilleiste 22 am oberen Rand des stationären Seitenwandteils 6 einsteckbar ist und mittels der seitlichen Halteleisten 14 an der Kabinenwand sicherbar ist. Anstelle eines Spiegelglases kann ein durchsichtiges Scheibenglas aus Verbundglas eingesetzt werden, oder ein Panel aus Holz, Kunststoff oder Metall oder aus einer Kombination dieser Materialien.The removable side wall part 3 may be a mirror glass, which can be inserted into a profiled strip 22 at the upper edge of the stationary side wall part 6 and by means of the lateral retaining strips 14 on the cabin wall is securable. Instead of a mirror glass, a transparent glass pane made of laminated glass can be used, or a panel made of wood, plastic or metal or a combination of these materials.
[0010] Die Figur 5 zeigt die Liftkabine in ihrer obersten Position im Liftschacht, und zwar in einem Schnitt von der Seite her gesehen. Man sieht, dass in dieser obersten Position der Liftkabine der Liftmotor 26 seitlich neben der Liftkabine liegt, bzw. dass die Liftkabine bis neben den Liftmotor 26 verfahrbar ist. Die Trag- und Zugseile 7 laufen in zwei Ebenen, wobei die eine Ebene recht nahe bei der Liftkabine liegt. In Figur 6 ist das Wartungsfenster geöffnet. Das obere Seitenwandteil 3 ist entsprechend vor dem unteren Seitenwandteil 6 auf den Kabinenboden 1 abgestellt, und zwar in einem gewissen Abstand. Dieser wird durch die oben beschriebenen Distanzhalter definiert, entweder durch einen stationären Handlauf 5, oder aber durch mindestens einen Distanzbügel 19, der bei Bedarf auf der Rückseite des wegnehmbaren Seitenwandteils 3 schwenkbar oder aufklappbar sind. In der Figur 6 erkennt man wie von diesem wegnehmbaren Seitenwandteil 3 eine Brüstung 4 gebildet ist. Von der Innenseite der Brüstung 4 aus bis zum ersten Seil 7 müssen mindestens 10cm Abstand eingehalten werden, was mit dieser Anordnung mühelos erreicht werden kann. [0011] Schliesslich zeigt die Figur 7 eine Ansicht der Liftkabine mit durch das geöffnete Wartungsfenster zugänglichem Liftmotor 26. Dieser besteht hier aus einem Traktionsantrieb mit einem Aussenläuferrohr, welches als Treibrohr dient, und über welches die Seile 7 laufen, die hier allerdings nicht eingezeichnet sind. Als Besonderheit ist dieser Traktionsantrieb an einer Brücke 25 aufgehängt, die über Befestigungsbügel 27 auf den inneren Führungsschienen 23 für das Gegengewicht aufliegt, während diese Bügel 27 an den äusseren Führungsschienen 24 für die Liftkabine befestigt sind. Das Wartungsfenster ist bis auf das untere, zum Beispiel 90cm hohe Seitenwandteil 6 offen. Es erstreckt sich praktisch über die ganze Breite der Liftkabine. Vor dieses Wartungfenster wird jetzt das abnehmbare Seitenwandteil 3 gestellt, sodass dessen oberer Rand 4 das untere Seitenwandteil 6 um 10cm überragt und eine Brüstung 4 bildet. In der Figur erkennt man die Schienen 23 für die Führung des Gegengewichtes, und ausserhalb des Motors angeordnet verlaufen parallel dazu die Schienen 24 für die Führung der Liftkabine. Dieser spezielle Liftantrieb ist jedoch nicht Gegenstand dieser Erfindung, sondern bloss eine Hintergrundinformation. Die Liftkabine mit diesem Wartungsfenster kann auch für andere Antriebskonstruktionen realisiert werden.Figure 5 shows the elevator car in its uppermost position in the elevator shaft, in a section seen from the side. It can be seen that in this uppermost position of the elevator car, the lift motor 26 is located laterally next to the elevator car, or that the lift cabin can be moved up to the lift motor 26. The carrying and traction cables 7 run in two planes, with one plane lying very close to the elevator car. In Figure 6, the maintenance window is open. The upper side wall part 3 is placed accordingly in front of the lower side wall part 6 on the cabin floor 1, and that at a certain distance. This is defined by the above-described spacers, either by a stationary handrail 5, or by at least one spacer bracket 19, which are pivotable or hinged if necessary on the back of the removable side wall part 3. In FIG. 6 it can be seen how a parapet 4 is formed by this removable side wall part 3. From the inside of the parapet 4 to the first rope 7 at least 10cm distance must be maintained, which can be easily achieved with this arrangement. Finally, Figure 7 shows a view of the elevator car with accessible through the open maintenance window lift motor 26. This consists of a traction drive with an outer rotor tube, which serves as a driving tube, and over which the ropes 7 run, which are not shown here , As a special feature of this traction drive is suspended on a bridge 25 which rests on mounting bracket 27 on the inner guide rails 23 for the counterweight, while these brackets 27 are attached to the outer guide rails 24 for the elevator car. The maintenance window is open except for the lower, for example 90 cm high side wall part 6. It extends practically across the entire width of the elevator car. Before this maintenance window, the removable side wall part 3 is now placed so that its upper edge 4, the lower side wall portion 6 surmounted by 10cm and a parapet 4 forms. In the figure can be seen the rails 23 for the guidance of the counterweight, and arranged outside the engine run parallel to the rails 24 for the guidance of the elevator car. However, this particular lift drive is not the subject of this invention, but merely a background information. The lift cabin with this maintenance window can also be realized for other drive constructions.
[0012] Diese Liftkabine mit Wartungsfenster ermöglicht es erstmals, einen Lift ausschliesslich von der Liftkabine aus zu warten und zu kontrollieren. Voraussetzung ist freilich, dass alle antriebsrelevanten Elemente auf einer einzigen Seite der Liftkabine untergebracht sind. Die Liftkabine hat hierzu ein L- förmiges Chassis, und die Schienen für die Führung der Liftkabine wie auch jene für das Gegengewicht verlaufen hinter dem stehenden Schenkel des L's. Ebenfalls der Liftmotor, in welcher Form auch immer ausgeführt, ist hinter dem stehenden Schenkel des L's angeordnet, wie auch alle Umlenkrollen, alle Befestigungselemente für die Seile und Schienen, und auch alle Endschalter. Damit sind alle diese Elemente durch das Wartungsfenster einsehbar und von der Kabine aus zugänglich. Die Wartung erfolgt ausschliesslich aus der Liftkabine heraus und ist deshalb für den Liftmonteur sehr viel komfortabler und sauberer und ausserdem erst noch rascher und sicherer durchzuführen. This lift cabin with maintenance window makes it possible for the first time to wait and control a lift exclusively from the elevator car. The prerequisite is, of course, that all drive-relevant elements are accommodated on a single side of the elevator car. The lift cabin has an L-shaped chassis for this purpose, and the rails for the guidance of the elevator car as well as those for the counterweight run behind the standing leg of the L's. The lift motor, in whatever form, is also located behind the upright leg of the L's, as well as all pulleys, all fasteners for the ropes and rails, as well as all limit switches. Thus, all these elements are visible through the maintenance window and accessible from the cab. The maintenance is carried out exclusively from the lift cabin and is therefore much more comfortable and cleaner for the lift fitter and also faster and safer.
