Definitions
- the invention relates to a hydraulic rope elevator with a backpack-guided car and a drive device arranged between the car guide rails.
- the invention is therefore based on the object of designing a hydraulic rope elevator with a backpack-guided car and consequently three-sided accessibility of the elevator shaft and the car in such a way that it can be provided with a better, simpler and more economical working drive.
- the invention provides that the drive device comprises a pull cylinder with a counterweight attached and a cable pull comprising a fixed and a loose roller, the counterweight, the deflection roller on the counterweight and the pull cylinder being arranged essentially in the vertical plane of the car guide rails and the cable acts laterally in the longitudinal center plane on a boom or a cross member of the car.
- the elevator according to the invention represents a combination of the construction with a backpack-guided car and the drive device with traction piston hydraulics, which was previously preferred because of the three-sided accessibility and the stress of only one shaft wall by the drive device, and a further special feature is that the car only uses one and more the cable pulling the car is not actuated in the central longitudinal axis.
- this enables a configuration such that a scaffold formed from the car guide rails and a plurality of cross members can carry the counterweight guide rails, the pull cylinder, the upper cable receptacle and the upper deflecting roller, and thus the entire drive can be a prefabricated component, which is also not a special one Breakouts and breakthroughs in the elevator shaft, but can be easily flange-mounted on a shaft wall.
- the upper deflection roller i.e. the deflection roller in the shaft head
- the deflection roller on the counterweight is arranged inclined to the deflection roller on the counterweight, in such a way that the cable sections between the fixed upper cable receptacle and the deflection roller on the counterweight, between this and the Deflection roller on the shaft head and finally run vertically between this deflection roller on the shaft head and the car.
- the lifting and lowering of the elevator does not result in any changed lever conditions due to a more or less inclined or vertical positioning of the cable pulls, as is the case with a number of traction piston hydraulics previously proposed, but all of them with central suspension and guidance of the elevator car work so that at least two, often also three shaft walls are blocked and in principle a maximum of two walls is available as an access option.
- the inclination of the upper deflection roller has the additional advantage that the rope suspension can be moved into the current center of gravity of the car by rotating the roller around the common rope run-up or rope run-off point, which is particularly the case with so-called "one-piston side systems", systems with a cylinder to the side of the door is important.
- the construction according to the invention allows a very compact design, since the pull cylinder, the counterweight, the deflection plate on the counterweight, the guides for the counterweight, the cable guide and the deflection roller unit including the roller block in the shaft head between the guide rails and are not arranged above the car, as was the case with the previous train cylinder hydraulics.
- the drive-over heights specified in the relevant regulations (TRA, EN 81) and thus the minimum headroom dimensions are very small.
- the deflection pulley unit in the shaft head and the mounting bracket for the pull cylinder can be attached directly to the structure or the rail using standard fastening elements (dowels, screws, Halfeniron etc.), no additional structural preparations such as cutouts in the shaft head or in the pit or that are required
- the introduction of cross members is required, which makes this system ideal for retrofitting existing systems.
- All main components of the drive device in particular the deflection roller unit in the shaft head, the support for the pull cylinder, the counterweight with rope pulley and guides as well as the brackets for the main and counterweight guide can be completely prefabricated and assembled, which significantly reduces the assembly time of the elevator.
- the pulleys are designed with regard to their number of grooves in such a way that they can accommodate the additional safety ropes required by the applicable regulations.
- FIG. 1 shows the elevator shaft 1 which is surrounded by the side walls 2 and the rear wall 2a.
- a frame-shaped scaffold 3 which is formed from two car guide rails 4, upper and lower cross members 5 and 6 and further interposed cross members 7.
- the car ropes 10 and the counterweight ropes 11 run vertically from the cable holder 15 on the upper cross member 5 via the rope pulley 12 on the counter weight 19 to the upper fixed deflection pulley 13 on the upper cross member 5 and from there to the rope suspension on the frame 14 can be seen in particular from FIG.
- the frame-shaped frame 3 including the guide rails 4 and the counterweight guide rails 16 and including the cable pulley 12 is arranged laterally outside the path of movement of the car 17; it is therefore a backpack-guided car.
- the axes of the two rope pulleys 12 and 13 run obliquely to one another, as a result of which the rope suspension on the frame 14 can take place outside the range of movement of the counterweight. Due to this arrangement, even with minimal space, i.e. in principle, contact between the car 17, the counterweight 19, the support cables 10 and the counterweight cables 11 is excluded with the smallest pitch dimension and the smallest distance to the wall. Another advantage of this arrangement is that by rotating the roller 13 around the common cable run-up or cable run-off point, the cable suspension 14 can be moved into the current center of gravity of the car.

Abstract
Description
Die Erfindung bezieht sich auf einen Hydroseilaufzug mit rucksackgeführtem Fahrkorb und einer zwischen den Fahrkorbführungsschienen angeordneten Antriebsvorrichtung.The invention relates to a hydraulic rope elevator with a backpack-guided car and a drive device arranged between the car guide rails.
In den letzten Jahren ist der Anteil hydraulischer Aufzüge zuungunsten der Seilaufzüge ständig gestiegen. Insbesondere die Kombination hydraulischer Druckzylinder mit rucksackgeführtem Korb hat sich wegen seines geringen Platzbedarfs und des nicht benötigten Maschinenhauses bei Personen- und kleineren Lastenaufzügen in der Praxis durchgesetzt.In recent years, the proportion of hydraulic lifts to the disadvantage of rope lifts has increased steadily. In particular, the combination of hydraulic pressure cylinders with a backpack-guided basket has proven itself in practice due to its small space requirement and the unnecessary nacelle for passenger and smaller freight elevators.
Der Nachteil dieser rucksackgeführten Hydroseilaufzüge besteht jedoch in dem relativ hohen Energieverbrauch, der hohen Antriebsleistung und den daraus resultierenden höheren Betriebskosten, da Antriebe mit Druckzylinder zwangsweise ohne Gegengewicht auskommen müssen.The disadvantage of these backpack-guided hydraulic rope lifts, however, is the relatively high energy consumption, the high drive power and the resulting higher operating costs, since drives with pressure cylinders have to do without a counterweight.
Zu Verbesserung dieser Situation sind daher auch in unterschiedlichen Ausführungsformen Hydroseilaufzüge mit Zugkolbenhydrauliken vorgeschlagen worden, bei denen ein Teil des Fahrkorbgewichts durch ein an der Kolbenstange montiertes Gegengewicht kompensiert wird. Alle bislang bekanntgewordenen Hydroseilaufzüge mit Zugkolbenhydraulik und Gegengewicht benötigen jedoch einen zentralgeführten Fahrkorb mit einer sehr aufwendigen Seilführung sowie einer Vielzahl von Seilrollen, insbesondere bei niedrigen Schachtköpfen, da dann ein Rolleneinbau oberhalb des Schachtkopfes wegen der vorgeschriebenen Überfahrhöhen ausgeschlossen ist. Jede Seilrolle bedeutet jedoch einen Antriebsverlust von etwa 5 bis 7 %, wobei weiterhin die Gefahr einer Seilbeschädigung und Abnutzung hinzu kommt, die mit jeder Umlenkrolle größer wird.To improve this situation, hydraulic cable lifts with traction piston hydraulics have therefore also been proposed in various embodiments, in which part of the car weight is compensated for by a counterweight mounted on the piston rod. However, all hydraulic rope hoists with traction piston hydraulics and counterweight that have become known require a centrally guided car with a very complex rope guide as well as a large number of rope pulleys, especially with low shaft heads, since roller installation above the shaft head is then impossible due to the prescribed drive-over heights. However, each pulley means a loss of drive of about 5 to 7%, with the added risk of rope damage and wear, which increases with each pulley.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Hydroseilaufzug mit rucksackgeführtem Fahrkorb und demzufolge dreiseitiger Zugänglichkeit des Aufzugschachts und des Fahrkorbs so auszugestalten, daß er mit einem besseren, einfacheren und wirtschaftlicher arbeitenden Antrieb versehen werden kann.The invention is therefore based on the object of designing a hydraulic rope elevator with a backpack-guided car and consequently three-sided accessibility of the elevator shaft and the car in such a way that it can be provided with a better, simpler and more economical working drive.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Antriebsvorrichtung einen Zugzylinder mit aufgesetztem Gegengewicht und einen eine feste und eine lose Rolle umfassenden Seilzug umfaßt, wobei das Gegengewicht, die Umlenkrolle am Gegengewicht und der Zugzylinder im wesentlichen in der vertikalen Ebene der Fahrkorbführungsschienen angeordnet sind und der Seilzug seitlich in der Längsmittelelbene an einem Ausleger oder einem Querholm des Fahrkorbs angreift.To achieve this object, the invention provides that the drive device comprises a pull cylinder with a counterweight attached and a cable pull comprising a fixed and a loose roller, the counterweight, the deflection roller on the counterweight and the pull cylinder being arranged essentially in the vertical plane of the car guide rails and the cable acts laterally in the longitudinal center plane on a boom or a cross member of the car.
Der erfindungsgemäße Aufzug stellt quasi eine Kombination des bisher wegen der dreiseitigen Begehbarkeit und der Beanspruchung nur einer Schachtwand durch die Antriebsvorrichtung bevorzugten Konstruktion mit rücksackgeführtem Fahrkorb und der Antriebsvorrichtung mit Zugkolbenhydraulik dar, wobei eine weitere Besonderheit darin besteht, daß der Fahrkorb nur mittels eines und noch dazu nicht in der Mittellängsachse am Fahrkorb angreifenden Seilzug betätigt wird. Dies ermöglicht in Weiterbildung der Erfindung eine Ausgestaltung derart, daß ein aus den Fahrkorbführungsschienen und mehreren Querträgern gebildetes Gerüst die Gegengewichtsführungsschienen, den Zugzylinder, die obere Seilaufnahme und die obere Umlenkrolle tragen kann und somit der gesamte Antrieb ein vorgefertigtes Bauteil sein kann, welches auch keine besonderen Ausbrüche und Durchbrüche im Aufzugsschacht erfordert, sondern sehr einfach an eine Schachtwand angeflanscht werden kann.The elevator according to the invention represents a combination of the construction with a backpack-guided car and the drive device with traction piston hydraulics, which was previously preferred because of the three-sided accessibility and the stress of only one shaft wall by the drive device, and a further special feature is that the car only uses one and more the cable pulling the car is not actuated in the central longitudinal axis. In a further development of the invention, this enables a configuration such that a scaffold formed from the car guide rails and a plurality of cross members can carry the counterweight guide rails, the pull cylinder, the upper cable receptacle and the upper deflecting roller, and thus the entire drive can be a prefabricated component, which is also not a special one Breakouts and breakthroughs in the elevator shaft, but can be easily flange-mounted on a shaft wall.
Mit besonderem Vorteil kann in Ausgestaltung der Erfindung vorgesehen sein, daß die obere Umlenkrolle, also die Umlenkrolle im Schachtkopf, geneigt zur Umlenkrolle am Gegengewicht angeordnet ist, derart, daß die Seilabschnitte zwischen der festen oberen Seilaufnahme und der Umlenkrolle am Gegengewicht, zwischen dieser und der Umlenkrolle am Schachtkopf und schließlich zwischen dieser Umlenkrolle am Schachtkopf und dem Fahrkorb jeweils vertikal verlaufen. Dadurch ergeben sich mit dem Anheben und Absenken des Aufzugs keine veränderten Hebelbedingungen durch ein sich mehr oder weniger Schräg- oder Vertikalstellen der Seilzüge, wie es bei einer Reihe von bisher vorgeschlagenen Zugkolbenhydrauliken der Fall ist, die noch dazu aber alle mit Zentralaufhängung und Führung des Fahrkorbs arbeiten, so daß mindestens zwei, oft auch drei Schachtwände blockiert sind und grundsätzlich maximal zwei Wände als Zugangsmöglichkeit zur Verfügung steht.It can be provided in a particularly advantageous embodiment of the invention that the upper deflection roller, i.e. the deflection roller in the shaft head, is arranged inclined to the deflection roller on the counterweight, in such a way that the cable sections between the fixed upper cable receptacle and the deflection roller on the counterweight, between this and the Deflection roller on the shaft head and finally run vertically between this deflection roller on the shaft head and the car. As a result, the lifting and lowering of the elevator does not result in any changed lever conditions due to a more or less inclined or vertical positioning of the cable pulls, as is the case with a number of traction piston hydraulics previously proposed, but all of them with central suspension and guidance of the elevator car work so that at least two, often also three shaft walls are blocked and in principle a maximum of two walls is available as an access option.
Die Schrägstellung der oberen Umlenkrolle hat den zusätzlichen Vorteil, daß durch Drehung der Rolle um den gemeinsamen Seilauflauf- bzw. Seilablaufpunkt die Seilaufhängung in den aktuellen Schwerpunkt des Fahrkorbs bewegt werden kann, was insbesondere bei sog. "Ein-Kolben-Seitlich-Anlagen", also Anlagen mit einem Zylinder seitlich neben der Tür, von Bedeutung ist.The inclination of the upper deflection roller has the additional advantage that the rope suspension can be moved into the current center of gravity of the car by rotating the roller around the common rope run-up or rope run-off point, which is particularly the case with so-called "one-piston side systems", systems with a cylinder to the side of the door is important.
Die erfindungsgemäße Konstruktion gestattet eine sehr kompakte Bauweise, da der Zugzylinder, das Gegengewicht, die Umlenkscheibe am Gegengewicht, die Führungen für das Gegengewicht, die Seilführung sowie die Umlenkrolleneinheit inklusive des Rollenbocks im Schachtkopf zwischen den Führungsschienen und nicht über dem Fahrkorb angeordnet sind, wie dies bei den bisherigen Zugzylinderhydrauliken der Fall war. Dadurch fallen die in den einschlägigen Verordnungen (TRA, EN 81) festgelegten Überfahrhöhen und somit die Schachtkopfmindestmaße sehr gering aus.The construction according to the invention allows a very compact design, since the pull cylinder, the counterweight, the deflection plate on the counterweight, the guides for the counterweight, the cable guide and the deflection roller unit including the roller block in the shaft head between the guide rails and are not arranged above the car, as was the case with the previous train cylinder hydraulics. As a result, the drive-over heights specified in the relevant regulations (TRA, EN 81) and thus the minimum headroom dimensions are very small.
Durch die Anwendbarkeit eines rucksackgeführten Fahrkorbs ist der Zugang zur Kabine prinzipiell über drei Seiten möglich, was bei den bisherigen indirekt wirkenden hydraulischen Zugkolbenanlagen nur von einer, max. zwei Seiten möglich war und somit einen erheblichen baulichen Vorteil bietet.Due to the applicability of a backpack-guided car, access to the cabin is in principle possible from three sides, which in the previous indirect-acting hydraulic pulling piston systems only required one, max. two sides was possible and thus offers a considerable structural advantage.
Die Verwendung von lediglich zwei Seilrollen gegenüber den bisher erforderlichen drei bis sechs Seilrollen bewirkt neben einer erheblichen Wirkungsgradverbesserung eine wesentlich höhere Lebensdauer der Seile und stellt die preiswerteste Lösung dar.The use of only two rope pulleys compared to the previously required three to six rope pulleys brings about a significant improvement in efficiency, a significantly longer lifespan of the ropes and is the cheapest solution.
Da die Befestigung der Umlenkrolleneinheit im Schachtkopf und des Befestigungsträgers für den Zugzylinder mittels Standardbefestigungselementen (Dübeln, Schrauben, Halfeneisen ect.) direkt am Bauwerk bzw. an der Schiene erfolgen kann, sind keinerlei zusätzliche bauliche Vorbereitungen wie Ausbrüche im Schachtkopf oder in der Grube oder das Einbringen von Querträgern erforderlich, wodurch sich dieses System vorzüglich für die Umrüstung bestehender Altanlagen eignet.Since the deflection pulley unit in the shaft head and the mounting bracket for the pull cylinder can be attached directly to the structure or the rail using standard fastening elements (dowels, screws, Halfeniron etc.), no additional structural preparations such as cutouts in the shaft head or in the pit or that are required The introduction of cross members is required, which makes this system ideal for retrofitting existing systems.
Sämtliche Hauptkomponenten der Antriebsvorrichtung, insbesondere die Umlenkrolleneinheit im Schachtkopf, der Träger für den Zugzylinder, das Gegengewicht mit Seilrolle und Führungen sowie die Bügel für die Haupt- und Gegengewichtsführung lassen sich komplett vorfertigen und montieren, was die Montagezeit des Aufzugs wesentlich erniedrigt.All main components of the drive device, in particular the deflection roller unit in the shaft head, the support for the pull cylinder, the counterweight with rope pulley and guides as well as the brackets for the main and counterweight guide can be completely prefabricated and assembled, which significantly reduces the assembly time of the elevator.
Die Seilrollen sind hinsichtlich ihrer Rillenzahl derart ausgebildet, daß sie die nach den geltenden Vorschriften erforderlichen zusätzlichen Fangseile aufnehmen können.The pulleys are designed with regard to their number of grooves in such a way that they can accommodate the additional safety ropes required by the applicable regulations.
Die Erfindung soll nachstehend an einem Ausführungsbeispiel sowie anhand der Zeichnung näher erläutert werden. Dabei zeigen:
- Fig. 1
- einen schematischen Vertikalschnitt durch den Aufzugsschacht eines erfindungsgemäßen Hydroseilaufzugs parallel zur Schachtwand, an der die Antriebsvorrichtung montiert ist, und
- Fig. 2
- einen schematischen vergrößerten Horizontalschnitt durch den Schacht längs der Linie II-II in Fig. 1.

- a schematic vertical section through the elevator shaft of a hydraulic rope elevator according to the invention parallel to the shaft wall on which the drive device is mounted, and
- Fig. 2
- a schematic enlarged horizontal section through the shaft along the line II-II in Fig. 1st
In Fig. 1 erkennt man den Aufzugsschacht 1, der von den Seitenwänden 2 und der Rückwand 2a umgeben ist. Innerhalb des Schachts befindet sich ein rahmenförmiges Gerüst 3, welches aus zwei Fahrkorbführungsschienen 4, oberen und unteren Querträgern 5 und 6 sowie weiteren zwischengeschalteten Querträgern 7 gebildet wird. Am unteren Querträger 6 ist ein Differentialzylinder 8 befestigt, dessen Kolbenstange 9 mit einem Gegengewicht 19 verbunden ist. Die Fahrkorbseile 10 sowie die Gegengewichtsseile 11 verlaufen vertikal von der Seilaufnahme 15 am oberen Querträger 5 über die Seilrolle 12 am Gegengewicht 19 zur oberen festen Umlenkrolle 13 am oberen Querträger 5 und von dort zur Seilaufhängung am Rahmen 14. An den bügelförmigen Querträgern 7 sind, wie man insbesondere aus Fig. 2 erkennen kann, mittels Streben 18 die Führungsschienen 16 für das Gegengewicht 19 angebracht, welches zwischen den Führungsschienen 4 angeordnet ist. Das rahmenförmige Gerüst 3 inklusive der Führungsschienen 4 und der Gegengewichtsführungsschienen 16 sowie einschließlich der Seilrolle 12 ist seitlich außerhalb des Bewegungswegs des Fahrkorbs 17 angeordnet; es handelt sich mithin um einen rucksackgeführten Fahrkorb.1 shows the
Wie man insbesondere aus Fig. 2 erkennt, verlaufen die Achsen der beiden Seilrollen 12 und 13 schräg zueinander, wodurch die Seilaufhängung am Rahmen 14 außerhalb des Bewegungsbereichs des Gegengewichts erfolgen kann. Aufgrund dieser Anordnung ist selbst bei minimalstem Platzangebot, d.h. bei kleinstem Stichmaß und geringstem Abstand zur Wand eine Berührung zwischen dem Fahrkorb 17, dem Gegengewicht 19, den Tragseilen 10 und den Gegengewichtsseilen 11 prinzipiell ausgeschlossen. Ein weiterer Vorteil dieser Anordnung liegt darin, daß durch Drehung der Rolle 13 um den gemeinsamen Seilauflauf- bzw. Seilablaufpunkt die Seilaufhängung 14 in den aktuellen Schwerpunkt des Fahrkorbs bewegt werden kann.As can be seen in particular from FIG. 2, the axes of the two
