Definitions
- This invention relates to an elevator car with a special maintenance window.
- the lifts must be checked and maintained regularly. Essentially, the following elements must be checked and maintained: The rail fastenings, the support cables, the support cable fastenings, the grooves of the drive pulleys or the drive tube of a traction drive, the pulleys, the limit switches, the safety brake cable and its fastening, and the guides of the chassis or the Cabin as well as the counterweight.
- This work is conventionally carried out on most lifts with the lift fitter standing on the roof of the lift cabin. This roof must be built according to regulations and have a parapet.
- the elevator car For checking and maintenance, the elevator car is moved slowly or in slow stages over the entire route so that the elevator fitter sees all the necessary elements by checking with his eyes and has access with his hands to all elements on which he has to carry out maintenance work, such as tightening screws, Lubricate rotating parts, check mechanical tension, test the function of limit switches, etc.
- maintenance work such as tightening screws, Lubricate rotating parts, check mechanical tension, test the function of limit switches, etc.
- the lift fitter can then climb onto this platform, either via a ladder from the lift cabin or from Floor through the open elevator car. In another embodiment, he can reach the car roof from the next higher floor and from there climb down to this platform with a ladder.
- the cabin walls are equipped with windows, the window sashes of which can be swung open towards the cabin interior, or sliding windows are provided so that access to the lift shaft is released on the side of this window.
- windows Such a solution comes from the WO01 / 79104 , from the JP 10-231074 or the EP 1 031 528 B1 emerged.
- 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 is accessible for maintenance through this access opening from inside the car.
- the solutions presented there not all maintenance work can be carried out from inside the cabin.
- the drive unit is included WO01 / 79104 and also at JP 10-231074 above the cabin, the guide rails for the cabin itself are included EP 1 031 528 B1 outside the area accessible from the cabin, namely on those side surfaces of the cabin that cannot be opened.
- the attachment and the condition of these guide rails can therefore not be checked from the cabin.
- the cable guides and their fastenings are also designed in such a way that they cannot be checked from the cabin.
- the object of the present invention is to create a car with a maintenance window which is suitable for lifts, all of the elements to be serviced and checked are located on a single side outside the lift car and are therefore accessible through an open car side wall. In this case, however, regulations must also be met. This is because the distance from the parapet, up to which the fitter can stand, to the ropes or other moving parts of the conveyor device must be be at least 10 cm.
- a lift cabin with a maintenance window for a lift in which all the elements to be serviced and tested are arranged opposite a single side of the lift car and which is characterized by the fact that on this side a part that is more than 85 cm above the car floor of the car wall is removable towards the inside of the car, this part is at least 95cm high and, after being removed from the cabin floor, can be leaned against this cabin wall to form a parapet, with at least one spacer between this removable part and the lower part of the cabin wall, so that the distance from the interior of the cabin facing side of the side wall part placed on the floor up to the elements of the elevator drive moving relative to the moving elevator car is at least 10cm.
- FIG. 1 a view into the open elevator cabin is granted, seen from the access door.
- the side walls are formed by panels 3, 6, 15, which are held, for example, by lateral guide strips 14, which in turn are connected to the frame of the elevator car by plug-in or screw connections.
- a fuse strip 16 can, for example, be arranged running horizontally along the top of the car roof. This is equipped with a locking mechanism that can be opened with a triangular or square key by inserting it into hole 17 and then turning it.
- a second lift door 18 made of two door parts that can be horizontally displaced outward is arranged here.
- the left side wall is divided into an upper side wall part 3 and a lower side wall part 6.
- a cross brace 19 which carries a handrail 5, here in the form of a chrome steel tube, which is a few centimeters away from the side wall.
- a bar that can be grasped from behind can also be provided.
- the upper side wall part 3 here can be removed from the lift cabin side in just a few simple steps.
- the fuse strip 16 is first removed, by releasing the locking mechanism with a key.
- the lateral retaining strips 14 can be removed. These are, for example, inserted into profile strips at the bottom and connected to the frame of the lift cabin at the top by a plug-in or screw connection.
- the side wall part 3 which is preferably 100 cm high, is placed on the floor 1 of the cabin and leaned against the handrail 5, it forms with its upper edge 4 a parapet in accordance with the regulations for the lift fitter who can now access the elements through the open maintenance window the lift drive can carry out its work. So that the lift cabin can be driven with the maintenance window open during this work and even more so for the purpose of performing this work, it must always be ensured that there is a prescribed distance between the parapet and the closest parts moving relative to the lift cabin of at least 10 cm.
- the dismantled side wall part 3 and placing 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 in order to save space in the lift shaft.
- the carrying and drive cables 7 and the guide rails 8 for the elevator car and the counterweight By placing the removed side wall part 3 inwards into the cabin interior, this required distance of 10 cm can easily be maintained, as can be seen in the figure.
- this parked side wall part 3 is now secured against falling over and at the same time it is achieved that the elevator car can be driven again. That is based on the Figure 3 explains where you can see the upper side wall part 3 shown on the elevator car floor in front of the lower side wall part 6, seen from the side.
- a cable holder 9 is mounted on the outside of the elevator car, and a two-pole cable 11 leads from this cable holder 9 to an end connector 12.
- this connector 12 can be plugged into a socket 13 on the back of the removable upper side wall part 3 is mounted.
- the two poles of the plug 12 are electrically connected to one another. As soon as the plug 12 is plugged into the socket 13, a circuit is closed so that the elevator car can be moved.
- This plug connection secures 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 can be moved.
- the elevator car can only be moved if the dismantled side wall part 3 is correctly parked in front of the lower side wall part 6 and thus, firstly, a parapet 4 is formed with the required minimum distance from the moving parts, such as the ropes 7 passing by, and secondly, the circuit for driving the lift cabin is closed.
- this contact can only be closed with the side wall part 3 correctly positioned, because only then can the piercer 12 be inserted into the socket 13 and the circuit closed.
- a bracket which is mounted on the back of the side wall part 3 can also serve.
- This solution is used for lifts that do not have a handrail for reasons of space. she is in Figure 4 shown.
- a bracket 19 is pivotably mounted on a holder 21 which is mounted on the rear side of the side wall part 3. In the swiveled-away position it simply hangs on the pivot bearing and is only slightly exposed to the rear on the rear side of the side wall part 3.
- the lift fitter can pivot the bracket 19 upwards and put its end 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 from the moving parts, as shown, and the side wall part 3 cannot fall over. Then the next thing to do is complete the circuit, as it was before Figure 3 described.
- the removable side wall part 3 can be a mirror glass which can be inserted into a profile strip 22 on the upper edge of the stationary side wall part 6 and can be secured to the cabin wall by means of the lateral retaining strips 14.
- a transparent pane made of laminated glass can be used, or a panel made of wood, plastic or metal or a combination of these materials.
- the 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 elevator motor 26 lies laterally next to the elevator car, or that the elevator car can be moved as far as next to the elevator motor 26.
- the suspension and pulling cables 7 run in two levels, one level being very close to the elevator car.
- the maintenance window is open.
- the upper side wall part 3 is placed correspondingly in front of the lower side wall part 6 on the cabin floor 1, specifically at a certain distance. This is defined by the spacers described above, either by a stationary handrail 5, or by at least one spacer bracket 19, which can be pivoted or opened if required on the rear of the removable side wall part 3.
- a parapet 4 is formed from this removable side wall part 3. A distance of at least 10 cm must be maintained from the inside of the parapet 4 to the first rope 7, which can be easily achieved with this arrangement.
- FIG. 7 a view of the elevator car with the elevator motor 26 accessible through the open maintenance window.
- This here consists of a traction drive with an external rotor tube which serves as a driving tube and over which the ropes 7 run, which are not shown here, however.
- this traction drive is suspended from a bridge 25 which rests on the inner guide rails 23 for the counterweight via fastening brackets 27, while these brackets 27 are fastened 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 over the entire width of the elevator car.
- the removable side wall part 3 is now placed in front of this maintenance window so that its upper edge 4 projects over the lower side wall part 6 by 10 cm and forms a parapet 4.
- the figure shows the rails 23 for guiding the counterweight, and the rails 24 for guiding the elevator car, arranged outside the motor, run parallel thereto.
- this special lift drive is not the subject of this invention, but merely background information.
- the elevator car with this maintenance window can also be implemented for other drive constructions.
- This lift cabin with maintenance window makes it possible for the first time to maintain and control a lift exclusively from the lift cabin.
- the prerequisite is, of course, that all drive-related elements are housed on a single side of the elevator car.
- the elevator car has an L-shaped chassis, and the rails for guiding the elevator car and those for the counterweight run behind the standing leg of the L.
- the lift motor in whatever form, is arranged behind the standing leg of the L, as are all pulleys, all fastening elements for the ropes and rails, and also all limit switches. This means that all of these elements can be seen through the maintenance window and are accessible from the cabin. Maintenance is carried out exclusively from the lift cabin and is therefore much more convenient and cleaner for the lift fitter and also quicker and safer to carry out.

Description
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

Die Aufgabe der vorliegenden Erfindung ist es, eine Kabine mit Wartungsfenster zu schaffen, welche geeignet ist für Lifte, deren sämtliche zu wartende und zu prüfende Elemente sich auf einer einzigen Seite ausserhalb der 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.The object of the present invention is to create a car with a maintenance window which is suitable for lifts, all of the elements to be serviced and checked are located on a single side outside the lift car and are therefore accessible through an open car side wall. In this case, however, regulations must also be met. This is because the distance from the parapet, up to which the fitter can stand, to the ropes or other moving parts of the conveyor device must be be at least 10 cm.
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 task is solved by a lift cabin with a maintenance window for a lift in which all the elements to be serviced and tested are arranged opposite a single side of the lift car and which is characterized by the fact that on this side a part that is more than 85 cm above the car floor of the car wall is removable towards the inside of the car, this part is at least 95cm high and, after being removed from the cabin floor, can be leaned against this cabin wall to form a parapet, with at least one spacer between this removable part and the lower part of the cabin wall, so that the distance from the interior of the cabin facing side of the side wall part placed on the floor up to the elements of the elevator drive moving relative to the moving elevator car is at least 10cm.

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 maintain and control a lift exclusively from the lift cabin. The prerequisite is, of course, that all drive-related elements are housed on a single side of the elevator car. For this purpose, the elevator car has an L-shaped chassis, and the rails for guiding the elevator car and those for the counterweight run behind the standing leg of the L. The lift motor, in whatever form, is arranged behind the standing leg of the L, as are all pulleys, all fastening elements for the ropes and rails, and also all limit switches. This means that all of these elements can be seen through the maintenance window and are accessible from the cabin. Maintenance is carried out exclusively from the lift cabin and is therefore much more convenient and cleaner for the lift fitter and also quicker and safer to carry out.
