Definitions
- the present invention relates to an elevator, in particular a traction sheave elevator according to the preamble of claim 1 and the preamble of claim 6.
- an elevator is known from EP-A-0631 966 already known.
- traction sheave lifts have a car arranged in a hoistway and, moreover, an engine room in which the controller, engine, and other elevator components are located.
- the ropes run from one side of the traction sheave down to the car and from the other side to the counterweight. So that the service personnel can also stay on the car roof during a journey for maintenance or installation work, a minimum safety space is prescribed for this purpose above the car roof, from the car roof in the uppermost car cage position up to the lower edge of components arranged above it or up to the Bay ceiling is enough.
- elevators with lying outside the shaft engine room in the shaft head at most roller carrier for the pulleys of the supporting cables are arranged, which can also be arranged next to the claimed by the car shaft area.
- the drive In lifts with engine in the shaft, the drive can be arranged in the upper or lower part of the lift shaft between the area required by the car during its travel movement and a wall of the lift shaft.
- the disadvantage here is that because of the arrangement of the drive in the lift shaft not the entire cross-sectional area of the chute can be used for the car. The necessary with respect to a particular car larger dimensions of the lift shaft leads to higher overall costs for the elevator or space losses.
- a further disadvantage is that the drive in a large-sized car can not exceed a certain size, e.g. To require recesses in the shaft wall.
- the object of the present invention is therefore to provide a lift with elevator drive of conventional size arranged in the elevator shaft, without increasing the shaft head height in relation to elevators with an engine compartment lying outside of the lift shaft.
- the total cost of the elevator can be reduced.
- the drive in volume can be considerably larger and therefore more efficient than a narrow drive which can be attached only between the car and the shaft wall.
- the car in the shaft is normal as in an elevator with engine room outside of the Tray movable, with a prescribed security space between the car roof and the ceiling of the shaft is guaranteed in the second area of the car roof.
- the necessary height of the shaft is not higher than in conventional lifts with engine room above the shaft.
- the drive comprises a motor, a traction sheave for a lift with counterweight and at least one deflection roller.
- the invention according to claim 1 can also be used advantageously if instead of the entire drive only one or more pulleys are arranged above the car on roller carriers. It is possible, for example, to design the elevator with the machine below, and to arrange only the at least one deflection roller over the first area of the car roof. The area of the car roof below the pulley is locked in this case for a walk.
- the drive is expediently held together with further elevator components, in particular cable end suspensions and a speed limiter, in a machine frame which is carried by the shaft walls, by guide rails of the elevator or by the shaft ceiling.
- the individual elements of the drive can be pre-assembled in the machine frame in an advantageous manner, so that the drive thus mounted together with the machine frame is like a module in the lift shaft introduced. As a result, the assembly work on a construction site can be effectively reduced.
- the first area of the car roof is not accessible by using mechanical and / or electrical securing means. This ensures that the drive is not switched on or is switched off when the service personnel enters the locked area of the car roof.
- printing mats and / or infrared ray grid or motion sensors are arranged on the first area of the car roof, which can be activated in particular by entering the first area and prevent a drive or travel of the car.
- a triggering device for a track boundary for a counterweight of the elevator is arranged in the region of the car roof. Such a triggering device can be triggered if necessary, e.g. by entering the restricted area. This further enhances security for service personnel.
- an elevator with the features of claim 6 is proposed.
- This solution also advantageously allows a reduction of the shaft height compared to conventional lifts.
- the drive By arranging the drive at the height of the holder, namely the overall height of the holder and drive comprehensive assembly compared to conventional designs can be substantially reduced. This also makes it possible, with the same movability of the car to reduce the shaft height compared to the prior art and / or increase the drive if necessary.
- the holder is arranged in the shaft head over a first area of the car roof, and the second area of the car roof adjacent to the first area ensures the safety distance between the car roof and the shaft ceiling prescribed above the car, the car roof being accessible or accessible and the accessibility or accessibility being ensured Accessibility is limited to the second area.
- This embodiment essentially represents a combination of the two solutions according to the invention, and allows optimal utilization of the elevator shaft.
- the holder is formed by a machine frame which surrounds the drive substantially laterally. This ensures a particularly space-saving mounting of the drive, which can be fixed in the shaft in a simple manner.
- the drive can be made larger and more efficient in the contrary to previous solutions of drives in the shaft larger space.
- the drive from below or above between the carrier of the machine frame can be introduced and fastened in a desired position. This makes it possible to pre-assemble the drive in the machine frame, so that the entire assembly can be modularly introduced into a hoistway.
- a carrier of the machine frame rotatable or detachable, so that it can be brought into its supporting position after introduction of the drive in the machine frame.
- the machine frame and / or the drive arranged in the machine frame are arranged horizontally obliquely with respect to the shaft walls. This makes it possible to ensure a direct, favorable for the suspension cable connection between a counterweight and the car.
- the machine frame has recesses into which load-bearing areas of the drive engage, and / or support parts which project in the direction of the drive and around or in the bearing Drive parts engage, on.
- additional pulleys, Seilendaufhfitungen and / or speed limiter of the elevator can be attached to the machine frame.
- a pre-assembly is also possible with respect to these components, so that the installation effort or adjustment effort is reduced at the installation.
- the machine frame further assembly aids, in particular eyelets for the attack of hoists and / or pulleys for ropes, which are used for pulling up guide rails in a scaffolding elevator assembly of the elevator.
- a further mounting aid can be attached to the frame a hanger for a to be arranged in the slot control cabinet of the drive.
- the drive is supported in the frame by means of two suspension plates, each of which has a vertical plate area for horizontally screwing on the drive and a horizontal plate area for isolated support on or in the frame.
- machine frame can be fastened in shaft walls or in front of the shaft wall, on guide rails or on the shaft ceiling.

- the drive can also be equipped with a cable drum. Then the elevator comes off without counterweight.
- a height h 1 is provided, which corresponds to the necessary and prescribed safety distance. Due to the arrangement of the drive machine 30 in the pit head, this height is, however, limited in sections to the height h 2 , so that in a region 17a of the car roof 17, the safety distance is not guaranteed.
- a railing 18 is provided according to the invention for this reason, which delimits the safety space assigned to the area 17b from the area 17a of lower height. The railing 18 prevents service personnel from entering the area 17a of the car roof 17 while the elevator is moving. The stay of the service staff is thus limited to the area 17b.

Description
Die vorliegende Erfindung betrifft einen Aufzug, insbesondere einen Treibscheibenaufzug nach dem Oberbegriff des Patentanspruches 1 und dem Oberbegriff des Patentanspruches 6. Ein derartiger Aufzug ist aus der
Üblicherweise haben Aufzüge mit Treibscheibenantrieb einen in einem Fahrschacht angeordneten Fahrkorb und darüber einen Triebwerksraum, in dem Steuerung, Triebwerk und andere Aufzugkomponenten angeordnet sind. Dabei laufen die Seile von der einen Treibscheibenseite nach unten zum Fahrkorb und von der anderen Seite zum Gegengewicht. Damit das Servicepersonal sich auch während einer Fahrt für Wartungs- oder Montagearbeiten auf dem Fahrkorbdach aufhalten kann, ist für diesen Zweck über dem Fahrkorbdach ein Mindestsicherheitsraum vorgeschrieben, der vom Fahrkorbdach in der obersten Fahrkorbstellung nach oben bis zur Unterkante von darüber angeordneten Bauteilen bzw. bis zur Schachtdecke reicht. Im allgemeinen sind bei derartigen Aufzügen mit außerhalb des Schachtes liegendem Triebwerksraum im Schachtkopf höchstens Rollenträger für die Umlenkrollen der Tragseile angeordnet, die auch neben der vom Fahrkorb beanspruchten Schachtfläche angeordnet sein können.Typically, traction sheave lifts have a car arranged in a hoistway and, moreover, an engine room in which the controller, engine, and other elevator components are located. The ropes run from one side of the traction sheave down to the car and from the other side to the counterweight. So that the service personnel can also stay on the car roof during a journey for maintenance or installation work, a minimum safety space is prescribed for this purpose above the car roof, from the car roof in the uppermost car cage position up to the lower edge of components arranged above it or up to the Bay ceiling is enough. In general, in such elevators with lying outside the shaft engine room in the shaft head at most roller carrier for the pulleys of the supporting cables are arranged, which can also be arranged next to the claimed by the car shaft area.
Bei Aufzügen mit Triebwerk im Schacht kann der Antrieb im oberen oder unteren Teil des Fahrschachtes zwischen dem von dem Fahrkorb bei seiner Fahrbewegung benötigten Bereich und einer Wand des Fahrschachtes angeordnet sein. Nachteilig ist hierbei, daß wegen der Anordnung des Antriebes im Fahrschacht nicht die gesamte Querschnittsfläche des Fahrschachtes für den Fahrkorb ausgenutzt werden kann. Die bezüglich eines bestimmten Fahrkorbes notwendige größere Dimensionierung des Fahrschachtes führt zu höheren Gesamtkosten für den Aufzug bzw. Bauraumverlusten. Als weiterer Nachteil ist zu werten, daß der Antrieb bei einem groß dimensionierten Fahrkorb eine bestimmte Baugröße nicht überschreiten kann, ohne z.B. Aussparungen in der Schachtwand zu benötigen.In lifts with engine in the shaft, the drive can be arranged in the upper or lower part of the lift shaft between the area required by the car during its travel movement and a wall of the lift shaft. The disadvantage here is that because of the arrangement of the drive in the lift shaft not the entire cross-sectional area of the chute can be used for the car. The necessary with respect to a particular car larger dimensions of the lift shaft leads to higher overall costs for the elevator or space losses. A further disadvantage is that the drive in a large-sized car can not exceed a certain size, e.g. To require recesses in the shaft wall.
Zur Umgehung derartiger Schwierigkeiten ist in der

Es ist ferner wünschenswert, das Dach eines Aufzugfahrkorbes auch bei fahrendem Aufzug begehbar bzw. zugänglich auszubilden, so daß beispielsweise der Monteur sich für Wartungsarbeiten auf dem Fahrkorbdach aufhalten kann. Aus Sicherheitsgründen ist es hierbei notwendig, einen bestimmten Mindestabstand als Schutzraum für den Monteur zwischen Fahrkorbdach und den darüber angeordneten Bauteilen bzw. der Schachtdecke zu halten, wodurch die Verfahrbarkeit des Aufzugs nach oben begrenzt ist.It is also desirable to make the roof of a lift car accessible or accessible even when the elevator is moving, so that, for example, the fitter can stay on the car roof for maintenance work. For safety reasons, it is necessary to keep a certain minimum distance as a shelter for the fitter between the car roof and the components arranged above or the shaft ceiling, whereby the mobility of the elevator is limited upwards.
Aus der nachveröffentlichten
Aufgabe der vorliegenden Erfindung ist daher die Schaffung eines Aufzuges mit im Aufzugsschacht angeordnetem Aufzugantrieb herkömmlicher Größe, ohne die Schachtkopfhöhe gegenüber Aufzügen mit einem außerhalb des Fahrschachtes liegenden Triebwerksraum zu erhöhen. Insbesondere sollen auch durch eine Verringerung des Bauaufwandes die Gesamtkosten für den Aufzug gesenkt werden können.The object of the present invention is therefore to provide a lift with elevator drive of conventional size arranged in the elevator shaft, without increasing the shaft head height in relation to elevators with an engine compartment lying outside of the lift shaft. In particular, by reducing the construction costs, the total cost of the elevator can be reduced.
Diese Aufgabe wird gelöst durch einen Aufzug mit den Merkmalen des Patentanspruches 1.This object is achieved by a lift with the features of
Mit der erfindungsgemäßen Lösung ist es nun möglich, den Antrieb im Fahrschacht unmittelbar über dem Fahrkorb anzuordnen, ohne hierbei die notwendige Höhe des Fahrschachtes zu vergrößern. Durch Beschränkung der Begehbarkeit des Daches des Fahrkorbes auf einen bestimmten Bereich ist es möglich, unter Gewährleistung eines vorgeschriebenen Sicherheitsabstandes zwischen Fahrkorbdach und Decke des Fahrschachtes ausschließlich in diesem zugänglichen Bereich den Fahrkorb im wesentlichen bis an den durch den Sicherheitsabstand definierten minimalen Abstand zwischen Fahrkorbdach und Decke des Schachtes heranzufahren. Da bei den bekannten Aufzugsystemen mit im Schacht über dem Fahrkorb angeordnetem Antrieb dieser Mindestabstand zwischen Unterkante des Antriebes und Decke des Fahrkorbes eingehalten werden mußte, kann die Schachtkopfbauhöhe bei gleicher Verfahrbarkeit des Fahrkorbes erfindungsgemäß wesentlich verringert werden. Daneben kann der Antrieb im Volumen erheblich größer und damit leistungsfähiger sein als ein nur zwischen Fahrkorb und Schachtwand anbringbarer schmaler Antrieb. Die erfindungsgemäßen Vorteile ergeben sich in gleicher Weise bei einem in der Schachtgrube angeordneten Antrieb, wenn die Zugänglichkeit der Schachtgrube entsprechend beschränkt wird.With the solution according to the invention it is now possible to arrange the drive in the lift shaft directly above the car, without thereby increasing the necessary height of the lift shaft. By limiting the accessibility of the roof of the car to a particular area, it is possible, ensuring a prescribed safety distance between the car roof and ceiling of the lift shaft only in this accessible area the car substantially up to the distance defined by the safety distance between the car roof and the ceiling Approach shaft. Since in the known elevator systems with arranged in the shaft above the car drive this minimum distance between the lower edge of the drive and ceiling of the car had to be complied with, the Schachtkopfbauhöhe can be substantially reduced according to the invention with the same mobility of the car. In addition, the drive in volume can be considerably larger and therefore more efficient than a narrow drive which can be attached only between the car and the shaft wall. The advantages of the invention arise in the same way at a arranged in the pit drive, if the accessibility of the pit is limited accordingly.
Nach einer bevorzugten Ausgestaltung der Erfindung ist der Fahrkorb im Schacht normal wie bei einem Aufzug mit Triebwerksraum außerhalb des Schachtes verfahrbar, wobei ein vorgeschriebener Sicherheitsraum zwischen dem Fahrkorbdach und der Decke des Schachtes im zweiten Bereich des Fahrkorbdaches gewährleistet ist. Hierbei ist die notwendige Bauhöhe des Schachtes nicht höher als bei herkömmlichen Aufzügen mit Triebwerksraum über dem Schacht. Durch entsprechende Anordnung des Antriebs und des begehbaren Bereiches des Fahrkorbdaches kann der geforderte Sicherheitsabstand bzw. Sicherheitsraum zwischen Fahrkorbdach und Schachtdecke im begehbaren Bereich eingehalten werden.According to a preferred embodiment of the invention, the car in the shaft is normal as in an elevator with engine room outside of the Tray movable, with a prescribed security space between the car roof and the ceiling of the shaft is guaranteed in the second area of the car roof. Here, the necessary height of the shaft is not higher than in conventional lifts with engine room above the shaft. By appropriate arrangement of the drive and the accessible area of the car roof, the required safety distance or safety space between the car roof and the shaft ceiling in the accessible area can be maintained.
Erfindungsgemäß weist der Antrieb einen Motor, eine Treibscheibe für einen Aufzug mit Gegengewicht und wenigstens eine Umlenkrolle auf. Die Erfindung gemäß Anspruch 1 kann ebenso vorteilhaft angewendet werden, wenn statt des ganzen Antriebes nur eine oder mehrere Umlenkrollen über dem Fahrkorb an Rollenträgern angeordnet sind. Es ist beispielsweise möglich, den Aufzug mit unten nebenstehender Maschine auszubilden, und lediglich die wenigstens eine Umlenkrolle über dem ersten Bereich des Fahrkorbdaches anzuordnen. Der Bereich des Fahrkorbdaches unterhalb der Umlenkrolle wird in diesem Fall für eine Begehung gesperrt.According to the invention, the drive comprises a motor, a traction sheave for a lift with counterweight and at least one deflection roller. The invention according to
Zweckmäßigerweise ist der Antrieb zusammen mit weiteren Aufzugskomponenten, insbesondere Seilendaufhängungen und einem Geschwindigkeitsbegrenzer, in einem Maschinenrahmen gehalten, der von den Schachtwänden, von Führungsschienen des Aufzuges oder von der Schachtdecke getragen wird. Hierbei können in vorteilhafter Weise die einzelnen Elemente des Antriebes in dem Maschinenrahmen vormontiert werden, so daß der derart montierte Antrieb zusammen mit dem Maschinenrahmen modulartig in den Fahrschacht einbringbar ist. Hierdurch kann die Montagearbeit an einer Baustelle in wirksamer Weise verringert werden.The drive is expediently held together with further elevator components, in particular cable end suspensions and a speed limiter, in a machine frame which is carried by the shaft walls, by guide rails of the elevator or by the shaft ceiling. Here, the individual elements of the drive can be pre-assembled in the machine frame in an advantageous manner, so that the drive thus mounted together with the machine frame is like a module in the lift shaft introduced. As a result, the assembly work on a construction site can be effectively reduced.
Zweckmäßigerweise ist der erste Bereich des Fahrkorbdaches durch Anwendung mechanischer und/oder elektrischer Sicherungsmittel nicht betretbar. Hierdurch ist gewährleistet, daß der Antrieb nicht einschaltbar ist bzw. abgeschaltet wird, wenn das Servicepersonal den gesperrten Bereich des Fahrkorbdaches betritt.Conveniently, the first area of the car roof is not accessible by using mechanical and / or electrical securing means. This ensures that the drive is not switched on or is switched off when the service personnel enters the locked area of the car roof.
Besonders bevorzugt ist, daß auf dem ersten Bereich des Fahrkorbdaches Druckmatten und/oder Infrarotstrahlengitter bzw. Bewegungssensoren angeordnet sind, welche insbesondere durch Betreten des ersten Bereiches aktivierbar sind und eine Fahrt bzw. Weiterfahrt des Fahrkorbes verhindern.It is particularly preferred that printing mats and / or infrared ray grid or motion sensors are arranged on the first area of the car roof, which can be activated in particular by entering the first area and prevent a drive or travel of the car.
Zweckmäßigerweise ist im Bereich des Fahrkorbdaches eine Auslösevorrichtung für eine Fahrwegbegrenzung für ein Gegengewicht des Aufzuges angeordnet. Eine derartige Auslösevorrichtung kann im Bedarfsfall ausgelöst werden, z.B. durch das Betreten der gesperrten Fläche. Hierdurch wird die Sicherheit für das Servicepersonal weiter gesteigert.Conveniently, a triggering device for a track boundary for a counterweight of the elevator is arranged in the region of the car roof. Such a triggering device can be triggered if necessary, e.g. by entering the restricted area. This further enhances security for service personnel.
Zur weiteren Lösung der der Erfindung zugrundeliegenden Aufgabe wird ein Aufzug mit den Merkmalen des Anspruchs 6 vorgeschlagen. Auch diese Lösung ermöglicht in vorteilhafter Weise eine Verminderung der Schachthöhe gegenüber herkömmlichen Aufzügen. Durch Anordnung des Antriebes auf der Höhe der Halterung kann nämlich die Gesamtbauhöhe der Halterung und Antrieb umfassenden Baugruppe gegenüber herkömmlichen Konstruktionen wesentlich vermindert werden. Auch hierdurch ist es möglich, bei gleicher Verfahrbarkeit des Fahrkorbes die Schachthöhe gegenüber dem Stand der Technik zu verringern und/oder bei Bedarf den Antrieb zu vergrößern.To further solve the problem underlying the invention, an elevator with the features of claim 6 is proposed. This solution also advantageously allows a reduction of the shaft height compared to conventional lifts. By arranging the drive at the height of the holder, namely the overall height of the holder and drive comprehensive assembly compared to conventional designs can be substantially reduced. This also makes it possible, with the same movability of the car to reduce the shaft height compared to the prior art and / or increase the drive if necessary.
Erfindungsgemäß ist die Halterung im Schachtkopf über einem ersten Bereich des Fahrkorbdaches angeordnet, und der neben dem ersten Bereich liegende zweite Bereich des Fahrkorbdaches gewährleistet den über dem Fahrkorb vorgeschriebenen Sicherheitsabstand zwischen Fahrkorbdach und Schachtdecke, wobei das Fahrkorbdach begehbar bzw. zugänglich ausgebildet ist und die Begehbarkeit bzw. Zugänglichkeit auf den zweiten Bereich beschränkt ist. Diese Ausgestaltung stellt im wesentlichen eine Kombination der beiden erfindungsgemäßen Lösungen dar, und ermöglicht eine optimale Ausnutzung des Aufzugschachtes.According to the invention, the holder is arranged in the shaft head over a first area of the car roof, and the second area of the car roof adjacent to the first area ensures the safety distance between the car roof and the shaft ceiling prescribed above the car, the car roof being accessible or accessible and the accessibility or accessibility being ensured Accessibility is limited to the second area. This embodiment essentially represents a combination of the two solutions according to the invention, and allows optimal utilization of the elevator shaft.
Gemäß einer weiteren bevorzugten Ausführungsform wird die Halterung von einem Maschinenrahmen gebildet, der den Antrieb im wesentlichen seitlich umgibt. Hiermit ist eine besonders raumsparende Halterung des Antriebs gewährleistet, die in einfacher Weise im Schacht fixierbar ist. Daneben kann der Antrieb in dem im Gegensatz zu bisherigen Lösungen von Antrieben im Schacht größeren Bauraum größer und leistungsfähiger ausgeführt werden.According to a further preferred embodiment, the holder is formed by a machine frame which surrounds the drive substantially laterally. This ensures a particularly space-saving mounting of the drive, which can be fixed in the shaft in a simple manner. In addition, the drive can be made larger and more efficient in the contrary to previous solutions of drives in the shaft larger space.
Zweckmäßigerweise ist der Antrieb von unten oder oben zwischen Träger des Maschinenrahmens einbringbar und in einer gewünschten Position befestigbar. Hierdurch ist es möglich, den Antrieb im Maschinenrahmen vorzumontieren, so daß der gesamte Zusammenbau modulartig in einen Aufzugschacht eingebracht werden kann.Conveniently, the drive from below or above between the carrier of the machine frame can be introduced and fastened in a desired position. This makes it possible to pre-assemble the drive in the machine frame, so that the entire assembly can be modularly introduced into a hoistway.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, einen Träger des Maschinenrahmens drehbar oder lösbar auszubilden, so daß er nach Einbringen des Antriebs in den Maschinenrahmen in seine tragende Stellung bringbar ist. Hierdurch kann der Montageaufwand weiter vermindert werden.According to a preferred embodiment of the invention, it is provided to form a carrier of the machine frame rotatable or detachable, so that it can be brought into its supporting position after introduction of the drive in the machine frame. As a result, the assembly work can be further reduced.
Erfindungsgemäß sind der Maschinenrahmen und/oder der im Maschinenrahmen angeordnete Antrieb bezüglich der Schachtwände horizontal schräg angeordnet. Hierdurch ist es möglich, eine direkte, für das Tragseil günstige Verbindung zwischen einem Gegengewicht und dem Fahrkorb zu gewährleisten.According to the invention, the machine frame and / or the drive arranged in the machine frame are arranged horizontally obliquely with respect to the shaft walls. This makes it possible to ensure a direct, favorable for the suspension cable connection between a counterweight and the car.
Zweckmäßigerweise weist der Maschinenrahmen Aussparungen, in welche tragende Bereiche des Antriebs eingreifen, und/oder Tragteile, die in Richtung des Antriebes vorragen und um oder in tragende Antriebsteile greifen, auf. Durch derartige Maßnahmen ist die Positionierung bzw. Justierung des Antriebs innerhalb des Maschinenrahmens in einfacher Weise möglich.Expediently, the machine frame has recesses into which load-bearing areas of the drive engage, and / or support parts which project in the direction of the drive and around or in the bearing Drive parts engage, on. By such measures, the positioning or adjustment of the drive within the machine frame in a simple manner possible.
Vorteilhafterweise sind am Maschinenrahmen zusätzlich Umlenkrollen, Seilendaufhängungen und/oder Geschwindigkeitsbegrenzer des Aufzugs anbringbar. Durch Montage dieser Bauteile an ihrem betriebsmäßig vorgesehenen Orten ist auch bezüglich dieser Bauteile eine Vormontage möglich, so daß der Montageaufwand bzw. Justieraufwand am Einbauort verringert ist.Advantageously, additional pulleys, Seilendaufhängungen and / or speed limiter of the elevator can be attached to the machine frame. By mounting these components in their operationally intended locations, a pre-assembly is also possible with respect to these components, so that the installation effort or adjustment effort is reduced at the installation.
Zweckmäßigerweise weist der Maschinenrahmen weitere Montagehilfen auf, insbesondere Befestigungsösen für den Angriff von Hebezeugen und/oder Umlenkrollen für Seile, die zum Hochziehen von Führungsschienen bei einer gerüstlosen Aufzugmontage des Aufzuges verwendet werden. Als weitere Montagehilfe kann am Rahmen ein Aufhänger für einen im Schacht anzuordnenden Steuerschrank des Antriebs angebracht werden.Conveniently, the machine frame further assembly aids, in particular eyelets for the attack of hoists and / or pulleys for ropes, which are used for pulling up guide rails in a scaffolding elevator assembly of the elevator. As a further mounting aid can be attached to the frame a hanger for a to be arranged in the slot control cabinet of the drive.
Gemäß einer bevorzugten Ausgestaltung ist der Antrieb mittels zweier Aufhängeplatten im Rahmen gehaltert, von denen jede einen senkrechten Plattenbereich zum waagerechten Anschrauben des Antriebs und einen waagerechten Plattenbereich zum isolierten Abstützen auf oder in dem Rahmen aufweist.

FIG. 1 ,
Der Fahrschacht 14 des Aufzuges 10 ist durch Schachtwände 12 und eine Schachtdecke 13 begrenzt. Stockwerkseitig ist in der Schachtwand 12 eine durch eine Türleibung 22 begrenzte Türöffnung vorgesehen, die mittels einer Schachttür 20 verschlossen ist (vgl.
In dem Fahrschacht 14 ist ein Antrieb für den Fahrkorb 16 zu dessen vertikaler Verfahrung im Fahrschacht 14 angeordnet. Der Antrieb umfaßt eine Antriebsmaschine 30, die im Schachtkopf oberhalb des Fahrkorbes 16 angeordnet ist. Weitere Elemente des Antriebs, insbesondere eine Treibscheibe sowie Tragseile zur Verbindung der Antriebsmaschine 30 mit dem Fahrkorb 16 sind aus Gründen der Übersichtlichkeit nicht näher dargestellt.In the
Wie aus
Zwischen dem Fahrkorbdach 17 und der Schachtdecke 13 ist eine Höhe h1 vorgesehen, die dem notwendigen und vorgeschriebenen Sicherheitsabstand entspricht. Durch die Anordnung der Antriebsmaschine 30 im Schachtkopf ist diese Höhe jedoch abschnittsweise auf die Höhe h2 eingeschränkt, so daß in einem Bereich 17a des Fahrkorbdaches 17 der Sicherheitsabstand nicht gewährleistet ist. Zur Abgrenzung des die Sicherheitshöhe h1 aufweisenden Bereiches 17b des Fahrkorbdaches 17 ist aus diesem Grunde erfindungsgemäß ein Geländer 18 vorgesehen, das den dem Bereich 17b zugeordneten Sicherheitsraum von dem Bereich 17a niedrigerer Höhe abgrenzt. Durch das Geländer 18 wird das Servicepersonal daran gehindert, den Bereich 17a des Fahrkorbdaches 17 bei fahrendem Aufzug zu betreten. Der Aufenthalt des Servicepersonals ist somit auf den Bereich 17b beschränkt.Between the
Vorteilhafterweise sind zusätzlich zu dem Geländer 18 elektronische Sicherheitseinrichtungen vorzusehen. Dabei kann es sich beispielsweise um im Bereich 17a angeordnete Druckmatten bzw. Druckelemente oder andere elektrische Sicherungsmittel handeln, die bei Betreten dieses Bereiches 17a optische und/oder akustische Signale aussenden, die zum Verlassen dieses Bereiches auffordern, und/oder ein Verfahren des Fahrkorbes 16 blockieren. Als zusätzliche Mittel zur Sicherung bzw. Begrenzung der Fahrkorbdachabschnitte 17a und 17b können auch beispielsweise gespannte Netze oder Warnschilder oder schräg ausgebildete Dachflächen dienen.Advantageously, in addition to the
Bei dem erfindungsgemäßen Aufzug ist somit trotz Anordnung der Antriebsmaschine 30 innerhalb des Fahrschachtes 14 unmittelbar über dem Fahrkorb 16 gewährleistet, daß ausreichende Flächen bzw. Bereiche 17b des Fahrkorbdaches 17 unter Einhaltung der Sicherheitsbestimmungen für das Servicepersonal frei zugängig sind.In the elevator according to the invention thus despite arrangement of the
Im Vergleich hierzu zeigt die im gleichen Maßstab angefertigte Zeichnung der
Durch diese erfindungsgemäße Maßnahme und die Sperrung des Fahrkorbdaches unterhalb des Antriebs kann die Schachtdecke 13 im Vergleich zu dem in
Als weitere in den Maschinenrahmen einbringbare Komponenten sei beispielhaft auf Lotlehren zum Ausrichten von Führungsschienen und Schachttüren hingewiesen. Durch Anordnung bzw. Positionierung der entsprechenden Bauteile am Maschinenrahmen kann dieser ferner in vorteilhafter Weise selbst als Maßlehre verwendet werden.As further components that can be introduced into the machine frame, reference is made by way of example to soldering jigs for aligning guide rails and shaft doors. By arranging or positioning the corresponding components on the machine frame, this can also be advantageously used as a gauge.
Die Ausrichtung und/oder Befestigung der genannten Bauteile wie z.B. Schienen, Türen, Steuerschrank am bzw. im Maschinenrahmen 40 erfolgt vorteilhafterweise mittels am Maschinenrahmen 40 vorgesehener Montagehilfen bzw. Aufhänger.The alignment and / or attachment of said components such as e.g. Rails, doors, control cabinet on or in the
Hierbei erweist sich als zweckmäßig, die Antriebsmaschine des Antriebs 30 mittels zweier Aufhängeplatten am Maschinenrahmen zu halten, welche jeweils einen senkrechten Plattenbereich zum waagerechten Anschrauben der Maschine und einen waagerechten Plattenbereich zum isolierten Abstützen in dem Maschinenrahmen 40 aufweisen.In this case, it proves expedient to hold the drive machine of the
Gemäß
Zudem können auch weitere unter dem Maschinenrahmen im Schacht angeordnete Bauteile zu ihrer Montage an ortsgerecht am Rahmen über ihrem Einbauplatz angeordnete Aufhänger aufgehängt und so leicht endgültig befestigt werden wie z.B. der Steuerschrank oder die Führungsschienen für Fahrkorb und/oder Gegengewicht.In addition, other components arranged below the machine frame in the shaft can also be suspended for their installation on hangers which are arranged on the frame above their place of installation and thus can be permanently attached, such as for example. the control cabinet or the guide rails for car and / or counterweight.
Gegenüber bekannten Aufzügen ohne Triebwerksraum, in welchen zur Erhaltung eines Sicherheitsraumes oberhalb des Fahrkorbdaches eine sehr flach ausgebildete Antriebsmaschine seitlich neben dem Fahrkorbweg im Schacht oder in einer entsprechenden Schachtnische angeordnet wird, gestattet die vorliegende Erfindung die volle Ausnutzung des Schachtquerschnittes und die Verwendung einer herkömmlichen Antriebsmaschine, ohne daß auf eine begehbare Sicherheitszone auf dem Fahrkorbdach verzichtet werden muß. Durch die erfindungsgemäße Ausgestaltung mit einer Halterung, die im wesentlichen auf der gleichen Höhe wie gehalterte Antriebsteile angeordnet ist, erfolgt eine besonders einfache und platzsparende Anordnung des Antriebes im Schachtkopf. Die erfindungsgemäße Halterung beschränkt sich nicht auf eine den Antrieb und weitere Funktionsteile umgebende rechteckige Maschinenhalterung, sondern kann auch als aus zwei oder mehreren Strebenteilen zusammengesetztes winkliges, insbesondere U-förmiges Trägerelement sein.Compared to known lifts without engine room, in which a very flat trained drive machine is arranged laterally next to the car path in the shaft or in a corresponding slot niche to maintain a security space above the car roof, the present invention allows the full utilization of the shaft cross-section and the use of a conventional drive machine, without having to forego a walk-in safety zone on the car roof. The inventive design with a holder which is arranged substantially at the same height as salaried drive parts, there is a particularly simple and space-saving arrangement of the drive in the shaft head. The holder of the invention is not limited to a surrounding the drive and other functional parts rectangular machine mount, but may also be composed of two or more strut parts angled, in particular U-shaped support member.
Als besonders vorteilhaft erweist sich die Möglichkeit, die erfindungsgemäße Halterung mit beispielsweise der Antriebsmaschine und weiteren Funktionselementen vormontiert bestückt in den Schachtkopf einzusetzen, wodurch wertvolle Arbeitszeit an der Baustelle eingespart wird.Particularly advantageous is the possibility of using the holder according to the invention pre-assembled with, for example, the prime mover and other functional elements inserted into the shaft head, whereby valuable working time is saved at the construction site.
Die Erfindung eignet sich auch zur Verwendung bei Aufzügen mit Durchladung. Um dort bei an der auf der Seite der Antriebsmaschine liegenden Fahrkorbtür durchzuführenden Arbeiten eine zusätzliche Sicherung für das Servicepersonal vorzusehen, kann die Zuschaltung einer Fahrwegbegrenzung, wie sie von der Anmelderin in der
