The stop components are arranged on the extending end of a pivotably located collar arm in the area of the rope rollers or roller battery.

Description

Die Erfindung betrifft eine Seilbahn mit Seilentgleisungsschutz zur Verhinderung einer seitlichen Entgleisung eines auf Trag und/oder Niederhalterollen geführten ruhenden bzw. laufenden Seiles nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a cable car with derailment protection to prevent lateral Derailment of a resting or running rope guided on support and / or hold-down rolls according to the preamble of claim 1.

Seilbahnen dieser Art sind durch die CH-A-360 704 bekanntgeworden. Bei dieser Seilbahn ist sowohl auf der Einlauf- als auch auf der Auslaufseite der das laufende Seil führenden Rolle je eine das Seil umgreifende Gabel vorgesehen, wobei die beiden Gabeln durch einen Gelenkmechanismus verbunden sind, welcher eine der beiden Gabeln in der Betriebsstellung halt, in welcher die Gabel das Seil umgreift, während die andere Gabel aus dem Bereich des Seiles gehoben ist. Beim Einlaufen der Seilklemme in den Bereich der Seilrolle umgreift die erste in der Bahn der Seilklemme befindliche Gabel das Seil und wird durch die einlaufende Seilklemme aus der Betriebsstellung gehoben, wahrend gleichzeitig die an der Auslaufseite befindliche Gabel in den Bereich des Seiles verschwenkt wird, sodaß diese Gabel nunmehr den Seilentgleisungsschutz bewirkt. Abgsehen von der Vielzahl der erforderlichen Gelenke, die einen hohen Störungsfaktor ergeben, hat der bekannte Seilentgleisungsschutz den Nachteil, daß er eine Retourfahrt der Fahrbetriebsmittel nicht zuläßt, da in diesem Falle die sich retour bewegende Seilklemme die sich auf der Einlaufseite der Seilrolle befindliche Gabel nicht passieren könnte.Cable cars of this type have become known from CH-A-360 704. At this cable car is one on both the entry and the exit side of the reel that guides the rope provided the rope encompassing fork, the two forks by a hinge mechanism are connected, which holds one of the two forks in the operating position in which the fork grips the rope while the other fork is lifted out of the area of the rope. At the Running the rope clamp into the area of the rope pulley encompasses the first in the path of the rope clamp located fork the rope and is from the operating position by the incoming rope clamp lifted, while at the same time the fork located on the outlet side in the area of the rope is pivoted so that this fork now provides rope derailment protection. Except for The well-known has the multitude of the required joints, which result in a high disturbance factor Cable derailment protection has the disadvantage that it does not allow a return trip of the driving equipment, because in this case the return moving rope clamp located on the inlet side of the rope pulley located fork could not happen.

Aus der DE 319 939 ist eine Einrichtung bekannt, bei der eine in der maßgebenden Fahrtrichtung vor der Einlaufrolle angeordnete Führungsschiene durch einen besonderen Aufbau über der Klemme des Fahrbetriebsmittels gegen das Seil niedergedrückt wird, wodurch sich der Entgleisungsschutz des Seiles hebt und das Passieren der Klemme ermöglicht. Damit könnten nur Anlagen mit ausschließlich Tragrollen oder solche mit ausschließlich Niederhalterollen ausgestattet werden, was bei modernen Einseil-Schwebebahnen und Schleppliften nicht der Fall ist. Im Fall eines Defekts, etwa einer Blockade durch Aneisung usw. ist bei der maßgebenden Fahrtrichtung zwangsläufig eine Katastrophe die Folge, weil die Durchfahrt für die Klemme nicht freigegeben wird. Für die andere Fahrtrichtung ist aber der Entgleisungsschutz nicht gegeben, da die Schutzvorrichtung erst nach der auflaufenden Rolle angebracht werden kann.From DE 319 939 a device is known in which one is in the relevant direction of travel Guide rail arranged in front of the infeed roller thanks to a special structure above the clamp of the driving equipment is pressed against the rope, causing derailment protection of the rope lifts and allows the clamp to pass. This would only allow plants with exclusively idlers or those with hold-down rollers only, what this is not the case with modern single-rope monorails and drag lifts. In the event of a defect, a blockage due to ice formation etc. is inevitable in the decisive direction of travel Disaster is the result because the passage for the terminal is not released. For the other Protection against derailment is not given, however, since the protective device only after emerging role can be attached.

Aus der AT 164 628 B, CH 475 494, FR 2 389 523 und US 4 458 603 A sind Anordnung bekannt, welche zur seitlichen Führung des Seiles ein sternförmig ausgenommenes Rad (bzw. eine Scheibe) verwenden, das durch ein Anstoßen der Seilklemme in Bewegung gesetzt wird. Die Erfindung nach der CH 475 494 kann ein Entgleisen überhaupt nicht verhindern, da die Sicherungsrolle erst nach der Seileinlautrolle angeordnet ist. Der Stoßvorgang fällt bei den Fahrgeschwindigkeiten moderner Anlagen heftig aus und hat unangenehme Folgen, wie Geräuschentwicklung, Schwingungsvorgänge, Materialverschleiß. Eine schlag- und geräuschdämpfende Ausbildung, die nicht naher erklärt ist, erscheint nicht hinreichend befriedigend machbar. Voraussetzung für ein störungsfreies Funktionieren ist aber, daß das sternförmige Rad (bzw. Scheibe) bei der Annäherung einer Klemme in einer gewissen Grundstellung verharrt. Bei einer ungünstigen Stellung könnte die Klemme an einer Zacke des Kranzes anstoßen und das Rad (bzw. Scheibe) würde sich nicht drehen. Beschädigungen, Seilentgleisung usw. könnten die Folge sein. Wenn jedoch das Seil etwa durch Seitenwind u.a. seitlich wird und bereits an der Vorrichtung schleift, dann kann die Vorrichtung schon vor der herannahenden Klemme aus der Grundstellung zufolge der Seilreibung ausgelenkt werden (siehe oben). Derartige Konstruktionen erscheinen daher für Anlagen mit Personenbeförderung nicht geeignet und werden auch nicht ausgeführt.Arrangements are known from AT 164 628 B, CH 475 494, FR 2 389 523 and US 4,458,603 A, which has a star-shaped recessed wheel (or a disk) for lateral guidance of the rope use that is set in motion by pushing the rope clamp. The invention according to the CH 475 494 cannot prevent derailment at all, since the safety roller only after the rope entry roller is arranged. The impact process falls more modern at the driving speeds Systems violently and has unpleasant consequences, such as noise, Vibration processes, material wear. A shock and noise-reducing training that is not explained in more detail, does not appear to be sufficiently satisfactory. Requirement for a trouble-free functioning is that the star-shaped wheel (or disc) when approaching remains stuck in a certain basic position. In an unfavorable position, the Push the clamp on a spike of the ring and the wheel (or disc) would not turn. This could result in damage, derailment, etc. However, if the rope goes through Cross wind, etc. is laterally and already grinds on the device, then the device can already deflected from the basic position due to the rope friction before the approaching clamp be (see above). Such constructions therefore appear for systems Passenger transport is not suitable and will not be carried out.

Die Seilführungen auf den Trag- bzw. Niederhalterollen beruhen bei allen bekannten Anlagen darauf, daß das Rollenprofil (Futterrille und seitlicher metallischer Rollenbord) ein eng begrenztes Maß an Entgleisungsschutz gewährleisten.The cable guides on the support or hold-down rollers are based on all known systems insist that the roller profile (feed groove and lateral metal roller board) is a narrowly limited one Ensure a level of protection against derailment.

Die Aufgabe der vorliegenden Erfindung als Sicherheitseinrichtung besteht darin, einen Schutz vor einer seitlichen Seilentgleisung bei allen denkbaren Ursachen, wie Seitenwind, Stützenverschiebungen, Montagefehlern, Schaukeln und Seilschwingungen, zu gewährleisten. Die Schutzvorrichtung soll in allen Fällen, also auch bei einer Retourfahrt des Fahrbetriebsmittels funktionieren und bei allen Anlagen verwendbar sein und kein zusätzliches Risiko im Falle von Defekten an ihrer Konstruktion beinhalten.The object of the present invention as a safety device is to protect against lateral derailment for all conceivable causes, such as cross wind, To ensure column displacements, assembly errors, swings and rope vibrations. The Protective device should in all cases, including when the driving equipment is returned work and be usable with all systems and no additional risk in the case of Include defects in their construction.

Diese Aufgabe löst die Erfindung durch die Merkmale des kennzeichnenden Teiles des Patentanspruches 1.The invention solves this problem by the features of the characterizing part of the Claim 1.

Das oder die Sperrglied(er) begrenzt die seitliche Lageabweichung des Seiles auf der Rolle und verhindern ein seitliches Austreten des Seiles. Lediglich beim Passieren eines Fahrbetriebsmittels wird die mit dem Sperrglied verbundene Führungsschiene durch die Seilklemme kurzzeitig soweit vom Seil wegbewegt, daß die Seilklemme und damit das Fahrbetriebsmittel passieren kann. Diese Betätigung erfolgt stoßfrei. Anschließend kehrt die Vorrichtung wieder in ihre Grundstellung zurück. Während der kurzzeitigen Lösung des Sperrgliedes aus der Grundstellung besteht in Hinblick auf die Konstruktion der Seilklemme, der Seilsteifigkeit und der Massenträgheit des Seiles keine Entgleisungsgefahr. Im Falle einer Blockade, etwa durch Aneisung usw. wird die Sperrvorrichtung zwangsläufig durch die herannahende Seilklemme gelöst, indem sie vom Seil weggedrückt wird.The locking member (s) limits the lateral positional deviation of the rope on the reel and prevent the rope from escaping sideways. Only when passing a vehicle the guide rail connected to the locking member is temporarily so far by the cable clamp moved away from the rope that the rope clamp and thus the driving equipment can pass. This Operation is bumpless. The device then returns to its basic position back. During the short-term release of the locking element from the basic position With regard to the construction of the rope clamp, the rope rigidity and the inertia of the rope no risk of derailment. In the event of a blockage, for example due to ice formation, the Locking device inevitably released by the approaching rope clamp by removing it from the rope is pushed away.

Fig. 1 zeigt das Seil 7, welches auf einer Rolle 6 läuft. Die erfindungsgemäße Konstruktion wird durch einen Kragarm 3, der an der Rolle 6 bzw. Rollenbatterie gelagert ist, getragen. Vorzugsweise sind die Sperrglieder 1 an dem auskragenden Ende des im Bereich der Rollen 6 bzw. Rollenbatterie schwenkbar gelagerten Kragarms 3 angeordnet. Je nachdem ob es sich bei den Rollen 6 um Trag- oder Niederhalterollen handelt umgreift der Kragarm 3 mit dem (den) Sperrglied(ern) 1 das Seil 7 von oben bzw. unten. Der Kragarm 3 steht mit einer Führungsschiene 2 in starrer Verbindung und weist zwei vertikal angeordnete Sperrglieder auf die in der dargestellten Grundstellung des Entgleisungsschutzes das Seil 7 von oben derart umfassen, daß es seitlich nur in begrenztem Maß aus seiner Sollage ausweichen kann, und somit die Rolle 6 nicht verlassen kann. Die seitliche Lageabweichung des Seiles auf der Rolle kann auch nur auf einer Seite durch ein vertikales Sperrglied begrenzt sein.Fig. 1 shows the rope 7, which runs on a roller 6. The construction according to the invention is carried by a cantilever arm 3, which is mounted on the roller 6 or roller battery. The locking members 1 are preferably at the projecting end of the roller 6 in the region or roller battery pivotally mounted cantilever 3. Depending on whether it is the rollers 6 are supporting or hold-down rollers, the cantilever arm 3 engages with the Locking element (s) 1 the rope 7 from above or below. The cantilever 3 stands with one Guide rail 2 in rigid connection and has two vertically arranged locking members the rope 7 from above in the illustrated basic position of the derailment protection include that it can only escape to a limited extent from its target position, and thus cannot leave role 6. The lateral positional deviation of the rope on the reel can be limited only on one side by a vertical locking member.

Fig. 2 zeigt den erfindungsgemäßen Entgleisungsschutz beim Passieren einer Seilklemme 5. Die passierende Seilklemme 5 hebt die Fuhrungsschiene 2 und die damit starr verbundenen Sperrglieder 1 an, wodurch die mechanische Sperrvorrichtung vorübergehend gelöst wird und die Seilklemme 5 passieren kann. Während dieser kurzzeitigen Entriegelung ist die Entgleisungsgefahr unbedeutend, da bei Annäherung des Fahrbetriebsmittels der Seildruck an die Rolle 6, der stabilisierend wirkt, erheblich ansteigt. Nach dem Passieren der Seilklemme gelangt der Kragarm 3 durch sein Eigengewicht bzw. durch Federkraft oder eine magnetische Kraft wieder in die Grundstellung zurück, in welcher der Entgleisungsschutz wirksam ist.Fig. 2 shows the derailment protection according to the invention when passing a rope clamp 5. Die Passing rope clamp 5 lifts the guide rail 2 and the rigidly connected Locking members 1, whereby the mechanical locking device is temporarily released and the cable clamp 5 can pass. During this brief unlocking is the The risk of derailment is insignificant, since the rope pressure increases when the driving equipment approaches the role 6, which has a stabilizing effect, increases significantly. After passing the rope clamp the cantilever arm 3 reaches by its own weight or by spring force or a magnetic Force back to the basic position in which the derailment protection is effective.

Wie aus Fig. 3 ersichtlich, ist die Schwenkbewegung des Kragarms 3 durch die Anordnung zweier Anschläge 4'' begrenzt. Der Kragarm muß nur so weit schwenkbar sein, daß ein ungehindertes Passieren der Seilklemme möglich ist. Ein Auslenken über den notwendigen Schwenkbereich hinaus wird durch einen Anschlag 4'' verhindert, der zweite Anschlag 4'' definiert die Grundstellung. Durch die Anordnung einer am auskragenden Ende der Führungsschiene 2 über dem Seil 7 um eine horizontale Achse drehbar gelagerte Rolle 4' kann die Lage der Grundstellung, in der die Entgleisungssperre in Funktion ist, zusätzlich festgelegt werden. Die Rückkehr in die Gtundstellung, in welcher der Entgleisungsschutz wirkt, und ihre Aufrechterhaltung kann insbesondere durch das Eigengewicht der Konstruktion oder/und zusätzlich durch Federkräfte 4''' oder magnetische Kräfte sichergestellt werden. Die Gestaltung der Führungsschiene 2 mit an gebogenen Enden gewährleistet eine stoßfreie Betätigung des Entgleisungsschutzes durch die Seilklemme 5. Die symmetrische Gestaltung der gebogenen Führungsschiene 2 gestattet eine Funktion für beide Fahrtrichtungen, wenn dies erfolrderlich ist.3, the pivoting movement of the cantilever arm 3 is due to the arrangement two stops 4 '' limited. The cantilever only has to be pivoted so far that a free passage of the rope clamp is possible. A deflection over the necessary Swivel range beyond is prevented by a stop 4 '', the second stop 4 '' defines the basic position. By arranging one at the cantilevered end of the Guide rail 2 above the rope 7 rotatably mounted roller 4 'about a horizontal axis the position of the home position in which the derailment lock is in operation is also specified become. The return to the position in which derailment protection works and theirs Maintenance can in particular by the weight of the structure or / and can also be ensured by spring forces 4 '' 'or magnetic forces. The design the guide rail 2 with curved ends ensures smooth operation of the Protection against derailment through the rope clamp 5. The symmetrical design of the curved Guide rail 2 allows a function for both directions of travel if this is necessary.
