Abstract

The invention relates to an inclined elevator, in particular a freight or passenger elevator, on whose telescopic guide rails a carriage carrying a load-lifting member is movable. The invention is directed in particular towards such guide rails in which a larger change in diameter takes place from telescopic stage to telescopic stage. The essence of the invention consists in the fact that the distance between top and bottom roller or between top roller on the one hand and bottom roller and side roller of the carriage on the other hand is variable at the transition from one telescopic stage to the following telescopic stage in order to guarantee reliable bearing of the rollers against the guide rails. <IMAGE>

Description

Die Erfindung betrifft einen Schrägaufzug, insbesondere Material- oder Personenaufzug mit mehreren Teleskopschüssen, welche Führungsschienen für einen daran verfahrbaren, ein Lastaufnahmemittel tragenden Schlitten bilden, welcher mittels Oberrollen und Unterrollen an dem Schienenprofil geführt ist.The invention relates to an inclined elevator, in particular material or passenger elevator with a plurality of telescopic sections, which form guide rails for a carriage which can be moved there and which carries a load-carrying means and which is guided on the rail profile by means of upper rollers and lower rollers.

Es ist ein derartiger Schrägaufzug bekannt, bei dem zusätzlich zu den üblicherweise äußeren seitlichen Führungsrollen innere seitliche Führungsrollen angeordnet sind, welche gegenüber den äußeren seitlichen Führungsrollen elastisch verstellbar sind. Hierdurch ist eine Anpassung an unterschiedliche Durchmesser (Breiten) der Führungsschienen möglich. Bei der bekannten Vorrichtung ist somit eine elastische Nachstellvorrichtung hinsichtlich der Breite der hohlprofilartig ausgebildeten Führungsschienen gegeben, wobei die Nachstellung mittels Spiralfedern erfolgt (US-PS 3 891 062).Such an inclined elevator is known in which, in addition to the usually outer lateral guide rollers, inner lateral guide rollers are arranged, which are elastically adjustable relative to the outer lateral guide rollers. This enables adaptation to different diameters (widths) of the guide rails. In the known device there is thus an elastic adjustment device with regard to the width of the guide rails designed in the manner of a hollow profile, the adjustment being carried out by means of spiral springs (US Pat. No. 3,891,062).

Es ist ein weiterer, für den Materialtransport bestimmter Schrägaufzug bekannt, bei dem am Schlitten Schwingen angeordnet sind, welche die Ober-und Unterrollen tragen (DS-OS 3 222 508). Die Lagerung der Rollen an Schwingen soll das Uberfahren von Knickstellen erleichtern; zum anderen wird eine Vergleichmäßigung der Lastübertragung beim Ueberfahren der Schienenstöße erreicht.Another inclined elevator intended for the transport of material is known, in which the carriage has swing arms which carry the upper and lower rollers (DS-OS 3 222 508). The bearing of the rollers on the swingarms should make it easier to drive over kinks; on the other hand, the load transfer is evened out when the rail joints are passed over.

Die Rollenbestückung nach dem vorgenannten Std. d. T. ist vorzugsweise geeignet für Schrägaufzüge für den ausschließlichen Materialtransport, wie sie durch die DE-OS 35 41 836 bekannt geworden sind. Derartige Schrägaufzüge bestehen aus Teleskopschüssen, welche aus leiterartig verbundenen Schienenprofilen gebildet sind. Die bekannten Schienenprofile sind etwa U-förmig ausgebildet, also "offene" Profile, welche im Bereich ihrer zueinanderweisenden unteren Doppelschenkel durch Quergurte verbunden sind. Die Ober- und Unterrollen führen sich dabei oberhalb und unterhalb des Oberflansches dieser offenen Profile, so daß beim Uebergang von einem Teleskopschuß auf den folgenden Teleskopschuß vom Schlitten jeweils eine Flanschdicke überfahren werden muß. Die hieraus resultierenden Anforderungen an die Schlittenführung sind mit der technischen Lehre nach der DE-OS 32 22 508 so lange beherrschbar, wie das Profil im Bereich der Anlage der Ober- und Unterrollen sowie ggf. von Seitenrollen (Außen- oder Innenrollen) keine besondere Profilgebung erfährt, welche den Uebergang von einem Profil zum anderen wesentlich vergrößert.The roll assembly after the aforementioned hour d. T. is preferably suitable for inclined lifts for the exclusive material transport, as they have become known from DE-OS 35 41 836. Such inclined elevators consist of telescopic sections, which are formed from ladder-like connected rail profiles. The known rail profiles are approximately U-shaped, ie "open" profiles, which are connected in the region of their mutually facing lower double legs by cross belts. The upper and lower rollers run above and below the upper flange of these open profiles, so that in the transition from one telescopic section to the following telescopic section, a flange thickness must be passed by the slide. The resulting requirements for the slide guide can be mastered with the technical teaching according to DE-OS 32 22 508 as long as the profile in the area of the upper and lower rollers as well as side rollers (outer or inner rollers) is not particularly profiled experiences, which significantly increases the transition from one profile to another.

Bei der Gestaltung von Schrägaufzügen insbesondere für den Personen- oder ggf. kombinierten Personen- und Materialtransport soll aus Sicherheitsgründen geschlossenen Hohlprofilen der Vorzug gegeben werden, welche teleskopartig ineinandergesteckt und - mit Ausnahme des letzten, untersten Teleskopschusses - nur im Bereich ihrer oberen Enden durch eine Quertraverse verbunden sind. Die Ober- bzw. Unterrollen können nur an den Ober- bzw. Unterseiten dieser Profile geführt werden, wobei vom untersten Profil bis zum obersten Profil eine erhebliche Durchmesserveränderung gegeben ist, welcher durch die Erfindung Rechnung getragen werden soll. Bei derartigen Profilen finden als Zwangsausschubmittel bevorzugt Bolzenketten Verwendung, wie sie in der zum zweitrangigen Std. d. T gehörenden älteren deutschen Patentanmeldung P 36 28 447 bei Verwendung eines offenen Profiles beschrieben sind.When designing inclined elevators, in particular for the transportation of people or possibly combined people and materials, preference should be given to closed hollow profiles for safety reasons, which are telescopically nested and - with the exception of the last, lowest telescopic section - only in the area of their upper ends by a crossbar are connected. The upper or lower rollers can only be guided on the upper or lower sides of these profiles, a considerable diameter change being given from the lowest profile to the uppermost profile, which should be taken into account by the invention. In such profiles, bolt chains are preferably used as the forced extension means, as used in the second-order hour. T belonging to older German patent application P 36 28 447 are described when using an open profile.

Aufgabe der Erfindung ist es somit, einen Schrägaufzug der eingangs genannten Gattung dahingehend zu verbessern, daß bei relativ großen Abstandsveränderungen der Profilhöhe der Schienenführung beim Uebergang von einem Teleskopschuß zum nächstfolgenden eine sichere und zuverlässige Schlittenführung gegeben ist. Es soll gewährleistet sein, daß die Ober- bzw. Unterrollen unabhängig von der Ausfahrlänge der einzelnen Teleskopschüsse stets mit einem bestimmbaren Spiel bzw. mit einem bestimmbaren Anpreßdruck an den Führungsschienen anliegen, so daß das Lastaufnahmemittel exakt an den Führungsschienen geführt und - bei Bruch des Lastseiles - die aus dem Std. d. T. (DE-OS 32 33 508) bekannte Exzenterbremse sicher greifen kann.The object of the invention is therefore to improve an inclined lift of the type mentioned in such a way that with relatively large changes in the distance of the profile height of the rail guide during the transition from a telescopic shot to the next one there is a safe and reliable slide guide. It should be ensured that the upper and lower rollers are always in contact with the guide rails with a determinable play or with a determinable contact pressure, regardless of the extension length of the individual telescopic sections, so that the load-carrying means are guided exactly on the guide rails and - if the load cable breaks - which from the hour d. T. (DE-OS 32 33 508) known eccentric brake can grip safely.

Die Erfindung löst die Aufgabe durch die Merkmale des Anspruches 1.The invention solves the problem by the features of claim 1.

Hiernach ist am Schlitten eine Vorrichtung vorgesehen, welche beim Ueberfahren der Uebergangsstelle durch den Schlitten den Abstand der Rollen selbstätig verändert, so daß in Folge dieser selbstätigen Verstellung der Rollenabstand zwischen Oberrolle und Unterrolle beim Auffahren des Schlittens stufenweise verringert und beim Abfahren des Schlittens stufenweise vergrößert wird, so daß der Rollenabstand jeweils automatisch an die verringerte "Dicke" bzw. den verringerten "Durchmesser" des nächstfolgenden kleineren Profils bzw. umgekehrt angepaßt wird.According to this, a device is provided on the slide which automatically changes the distance of the rollers when the slide passes over the transition point, so that as a result of this automatic adjustment, the roller distance between the upper roller and lower roller is gradually reduced when the slide moves up and is gradually increased as the slide moves down , so that the roller spacing is automatically adapted to the reduced "thickness" or the reduced "diameter" of the next smaller profile or vice versa.

Nach der erfindungsgemäßen Lehre ist somit ausschließlich am Schlitten eine Vorrichtung vorgesehen, welche geeignet ist, den Rollen einen solchen Anpreßdruck zu vermitteln, daß sie selbsttätig beim Übergang von einer Schiene auf die andere sowohl der Breite als auch der Höhe nach dem verringerten bzw. vergrößerten Schienenprofil folgen.According to the teaching of the invention, a device is provided exclusively on the carriage, which is suitable for imparting such pressure to the rollers that they automatically change in width and height according to the reduced or enlarged rail profile when changing from one rail to the other consequences.

Der Rollenverstellung dient eine Gasfeder, welche zwischen dem Schlitten einerseits und der Unterrolle bzw. der Unterrolle und der Seitenrolle andererseits eingespannt ist.The roller adjustment is a gas spring which is clamped between the carriage on the one hand and the lower roller or the lower roller and the side roller on the other.

Derartige Gasfedern mit einer Vorspannung von beispielsweise 190 Kp sind geeignet, den nötigen Andruck für die Rollen aufzubringen und aufgrund ihres großen Verstellbereiches den Schlitten sicher an den sich im Querschnitt verändernden Schienen zu führen.Gas springs of this type with a preload of, for example, 190 Kp are suitable for applying the necessary pressure for the rollers and, because of their large adjustment range, reliably guide the slide on the rails, which change in cross-section.

Das Parallelogrammgelenk ermöglicht bei entsprechender Bemessung der Gelenkarme und der Schwenkwinkel eine gleichzeitige Verstellung sowohl der Unterrolle als auch der Seitenrolle über nur eine einzige Gasfeder, wobei die Abstimmung der Schwenkwinkel und Gelenkarme auf das Schienenprofil beim Übergang von einem Schienenprofil zum anderen stets sowohl die Anlage der Unterrolle als auch die Anlage der Seitenrolle gewährleistet.If the articulated arms and the swivel angle are appropriately dimensioned, the parallelogram joint enables simultaneous adjustment of both the lower roller and the side roller using only a single gas spring, whereby the adjustment of the swivel angle and articulated arms to the rail profile when moving from one rail profile to the other always means that the lower roller is in contact as well as the installation of the side roller.

Weitere Merkmale der Erfindung sind durch die Unteransprüche gekennzeichnet.Further features of the invention are characterized by the subclaims.

Es hat sich als vorteilhaft erwiesen, die Oberrolle abstandsunveränderlich am Schlitten anzuordnen und lediglich die Unterrolle sowie ggf. zur sicheren seitlichen Führung die Seitenrolle (Außenrolle) zwangszuverstellen, wobei die vorbeschriebene Zwangsverstellung bei geschlossenen Hohlprofilen wegen der großen Abstandsveränderung bei jedem Schienenübergang vom untersten bis zum obersten Profil Anwendung findet (Ansprüche 2 - 4).It has proven to be advantageous to arrange the top roller on the slide without changing the distance and only to force-adjust the bottom roller and, if necessary, the side roller (outer roller) for safe lateral guidance Profile application applies (claims 2-4).

Erfindungsgemäß sind dem Schlitten an jeder Führungsschiene in Hintereinanderanordnung zwei Rollensätze (also insgesamt vier Rollensätze) zugeordnet, wobei jeder Rollensatz aus einer Oberrolle, einer Unterrolle und einer Seitenrolle besteht und wobei zumindest die jeweils "oberen" und "unteren" Rollensätze getrennt einstellbar sind (Anspruch 5). Dies ermöglicht es, die vorbeschriebenen Rollensätze unterschiedlich stark vorzuspannen, wobei es sich gemäß Anspruch 6 als vorteilhaft erwiesen hat, daß die in Aufzugsrichtung vordere Gasfeder den höheren Vorspanndruck aufweist, weil beim Aufziehen des Schlittens unter Last das Lastseil auf den Schlittenrahmen ein Moment ausübt, welches geeignet ist, den Abstand der in Aufzugsrichtung vorderen Rollen zu vergrößern.According to the invention, two sets of rollers (i.e. a total of four sets of rollers) are assigned to the carriage on each guide rail, each set of rollers consisting of an upper roller, a lower roller and a side roller, and at least the respective "upper" and "lower" roller sets can be set separately (claim 5). This makes it possible to pretension the roller sets described above to different extents, and it has proven advantageous according to claim 6 that the gas spring at the front in the elevator direction has the higher pretensioning pressure because when the sled is pulled up under load, the load cable exerts a moment on the sled frame which exerts a moment is suitable to increase the distance between the front rollers in the direction of the elevator.

Sofern es sich als zweckmäßig erweist, den Anpreßdruck zu verringern oder zu vergrößern, kann dies über eine verstellbare Lagerung der Gasfeder am Schlitten oder am Rollensatz vollzogen werden (Anspruch 7), wobei vorzugsweise jedem Rollensatz eine Gasfeder zugeordnet ist (Anspruch 8).If it proves expedient to reduce or increase the contact pressure, this can be carried out by means of an adjustable mounting of the gas spring on the slide or on the roller set (claim 7), preferably a gas spring being assigned to each roller set (claim 8).

Nach einem weiteren Merkmal der Erfindung (Anspruch 9) sind die die beiden benachbarten Führungsschienen eines Teleskopschusses verbindenden Quertraversen in der Schienenfolge wechselweise unterschiedlich ausgebildet, wobei bei einem Teleskopschuß im Querschnitt geschlossene Rechteckprofile und beim nächsten Teleskopschuß zwei mit Abstand voneinander angeordnete U-Profile vorgesehen sind, derart, daß die Länge der längeren Rechteckseite des im Querschnitt geschlossenen Rechteckprofiles kleiner ist als der Abstand zwischen den Stegen der U-Profile des nachfolgenden größeren Profiles. Auf diese Weise wird ermöglicht, daß zwischen den Stegen des U-Profile und außenseitig des Rechteckprofils die in den Ansprüchen 10 und 11 gekennzeichneten Zwangsausschubmittel bzw. Zwangseinschubmittel geführt werden können, wobei als Zwangsausschubmittel Bolzenketten gemäß der zum zweitrangigen Std. d. T. gehörenden deutschen Patentanmeldung P 3 628 447 und als Zwangseinschubmittel Rückholseite Verwendung finden können. Eine andere Bemessung der Quertraversen ist dann gegeben, wenn als Zwangsausschubmittel und Zwangseinschubmittel ein Mehrfachteleskopzylinder Verwendung findet, welcher in Folge einer Synchronbeaufschlagung gewährleistet, daß alle Teleskopstufen unter Zurücklegung gleicher Wege pro Zeiteinheit gleichzeitig zueinander ausfahren bzw. gleichzeitig zueinander einfahren.According to a further feature of the invention (claim 9), the crossbars connecting the two adjacent guide rails of a telescopic section are alternately designed differently in the rail sequence, rectangular sections having a closed cross-section being provided in the case of one telescopic section and two U-sections arranged at a distance from one another in the next telescopic section, such that the length of the longer side of the rectangle of the rectangular profile closed in cross section is smaller than the distance between the webs of the U-profiles of the subsequent larger profile. In this way it is possible that between the webs of the U-profile and outside of the rectangular profile, the forced extension means or forced insertion means characterized in claims 10 and 11 can be performed, with pin chains according to the second-order hour d. T. belonging German patent application P 3 628 447 and can be used as a forced insertion means return side. Another dimensioning of the crossbeams is given if a multiple telescopic cylinder is used as the forced extension means and forced insertion means, which, as a result of synchronous loading, ensures that all telescopic stages extend simultaneously to one another or retract to one another while covering the same distances per unit of time.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles unter Verwendung von sechs Teleskopschüssen (Schienen 1 - 6 näher erläutert.The invention is explained in more detail below using an exemplary embodiment using six telescopic sections (rails 1-6).

Die einzelnen Teleskopschüsse werden im folgenden mit dem Begriff "Schienen" bezeichnet.The individual telescopic sections are referred to below with the term "rails".

Aus der Fig. 1 ist der Schrägaufzug 7 ersichtlich, welcher teleskopierbare Schienen 1 - 6 aufweist, wobei die Schiene 5 gegenüber der Schiene 6 mittels eines aus Zylinder 35 und Kolbenstange 36 bestehenden Schubkolbengetriebes 37 teleskopierbar ist, wobei die Kolbenstange 36 an der Quertraverse 17 (Fig. 10) der Schiene 5 angeschlossen ist. Die Schienen 1 - 6 sind auf einem als fahrbarer Einachsanhänger ausgebildeten Fahrgestell 38 über eine Teleskopstütze 39 schwenkbar abgestützt.1 shows the inclined elevator 7, which has telescopic rails 1-6, the rail 5 being telescopic relative to the rail 6 by means of a thrust piston transmission 37 consisting of cylinder 35 and piston rod 36, the piston rod 36 on the cross-beam 17 ( Fig. 10) of the rail 5 is connected. The rails 1-6 are pivotally supported on a chassis 38 designed as a mobile single-axle trailer via a telescopic support 39.

Das mit 8 bezeichnete Lastaufnahmemittel ruht auf einem Schlitten 9, welcher über ein Lastseil mittels Winden 40 bewegt wird.The load-bearing means designated 8 rests on a carriage 9 which is moved by means of winches 40 over a load rope.

Es ist ersichtlich, daß jede aus zwei parallel zueinander angeordneten Schienenprofilen 13 bzw. 13' gebildete Schiene an ihrem oberen Ende 15 eine obere Quertraverse 17 aufweist.It can be seen that each rail formed from two parallel rail profiles 13 and 13 'has at its upper end 15 an upper crossbar 17.

Der Schlitten selbst besteht in seinem Grundaufbau (s. Fig. 5) aus zwei Längsträgern 40 sowie zwei U-förmigen Querträgern 41, welche einen nach unten weisenden Bügelschenkel 42 aufweisen. Der Längsträger 40 dient gleichzeitig dem Anschluß der Anschlußkonsole 44 für das Lastseil sowie der Exzenterbremse 45.The basic structure of the slide itself (see FIG. 5) consists of two longitudinal beams 40 and two U-shaped cross beams 41 which have a bow leg 42 pointing downward. The longitudinal member 40 also serves to connect the connection bracket 44 for the load rope and the eccentric brake 45.

Aus den Fig. 5, 8 und 9 ist erkennbar, daß an Konsolen 14 des Schlittengrundrahmens Gasfedern 34 angeschlossen sind, welche anderenends mit Buchsen 47 bzw. 47' verbunden sind. (In der Fig. 5 ist nur eine Gasfeder 34 dargestellt, vorzugsweise ist jedem aus Oberrolle 10, Unterrolle 11 und Seitenrolle 12 gebildeten Rollensatz eine Gasfeder zugeordnet.)5, 8 and 9 it can be seen that gas springs 34 are connected to brackets 14 of the slide base frame, which are connected at the other ends to bushings 47 and 47 ', respectively. (Only one gas spring 34 is shown in FIG. 5, a gas spring is preferably assigned to each roller set formed from the upper roller 10, lower roller 11 and side roller 12.)

Die Gasfeder 34 wirkt über den kurzen Arm 46 des oberen Gelenkarmes 26 auf die beiden Gelenkarme 26 eines Parallelogrammgelenkes, so daß durch die Gasfeder 34 das Parallelogrammgelenk verstellt werden kann. Die Buchsen 47 bzw. 47' sind frei drehbar auf einer Welle 49 angeordnet. Bei unterschiedlicher Vorspannung der Gasfedern 34 bzw. bei unterschiedlicher Anordnung (unterschiedliche Wirkstellung) an der Konsole bzw. an der Buchse kann so beispielsweise durch die in Aufzugsrichtung obere Gasfeder ein höherer Andruck als durch die untere Gasfeder erzeugt werden. Der untere Gelenkarm 26 (es sind in Bewegungsrichtung des Schlittens (Pfeilrichtung 27) jeweils zwei Gelenkarme 26 nebeneinander vorgesehen) ist einenends im Bereich des Bügelschenkels 42 an einer Achse 50 und anderenends drehbar an dem Rollenbock 53 angelenkt.The gas spring 34 acts via the short arm 46 of the upper articulated arm 26 on the two articulated arms 26 of a parallelogram joint, so that the parallelogram joint can be adjusted by the gas spring 34. The bushings 47 and 47 'are arranged on a shaft 49 so that they can rotate freely. With different prestressing of the gas springs 34 or with a different arrangement (different operative position) on the console or on the bushing can be generated, for example, by the upper gas spring in the elevator direction, a higher pressure than by the lower gas spring. The lower articulated arm 26 (two articulated arms 26 are provided next to each other in the direction of movement of the slide (arrow direction 27)) is articulated at one end in the area of the stirrup leg 42 on an axis 50 and at the other end on the roller block 53.

Der in Pfeilrichtung 27 versetzt angeordnete Gelenkarm 26 ist mit seinem unteren freien Ende drehbar am freien Ende der Achse 50 angeschlossen.The lower free end of the articulated arm 26, which is offset in the direction of the arrow 27, is rotatably connected to the free end of the axis 50.

Die unteren Enden der Bügelschenkel 42 sind durch einen Längsträger 52 miteinander verbunden.The lower ends of the stirrup legs 42 are connected to one another by a longitudinal member 52.

Aus Fig. 6 ist ersichtlich, daß bei Bewegung des Schlittens 9 in Pfeilrichtung 27 die Oberrolle 10 zunächst auf die Schiene 2 auflaufen wird, wobei sich der Rollenabstand a verändert. Diese Veränderung setzt sich fort beim Auflaufen auf die Schienen 3 und 4, so daß der Rollenabstand bei der Schiene 4 sich, wie durch a' gekennzeichnet, entsprechend vergrößert hat.From Fig. 6 it can be seen that when the carriage 9 moves in the direction of arrow 27, the upper roller 10 will first run onto the rail 2, the roller spacing a changing. This change continues when running onto the rails 3 and 4, so that the roller spacing on the rail 4 has increased accordingly, as indicated by a '.

Aus der Fig. 10 ist ersichtlich, daß zum Zwangsausschub der geschlossenen Hohlprofile jeweils vom oberen Ende 15 einer Schiene über das obere Ende 15 der nächstfolgenden Schiene zum unteren Ende 31 der folgenden Schiene (Festpunkt 54) eine als Flyerkette ausgebildete Bolzenkette 32 geführt ist.From Fig. 10 it can be seen that for the forced extension of the closed hollow profiles from the upper end 15 of a rail via the upper end 15 of the next rail to the lower end 31 of the following rail (fixed point 54) a pin chain 32 designed as a leaf chain is guided.

Dem Zwangseinschub gemäß Fig. 11 dient ein Rückholseil 33, welches jeweils vom oberen Ende 15 einer Schiene über das untere Ende 31 der folgenden Schiene zum oberen Ende 15 der nächstfolgenden Schiene geführt und dort befestigt ist.11 is a return cable 33, which is guided from the upper end 15 of one rail over the lower end 31 of the following rail to the upper end 15 of the next rail and is fastened there.
