Abstract

The invention relates to an inclined lift, in particular for the transport of goods or passengers with the use of a plurality of telescopic guide rails on which a slide is guided by means of top rollers and bottom rollers. The essence of the invention, in particular when closed hollow sections are used for the guide rails, is to automatically adapt the spacing of the top rollers and the bottom rollers to the increasing or reducing cross-sections of the guide rails by the slide rope (load rope) producing a constant applied pressure of the top rollers and bottom rollers against the rail section via a corresponding lever linkage. <IMAGE>

Description

Die Erfindung betrifft einen Schrägaufzug, insbesondere Material- und/oder Personenaufzug mit mehreren Teleskopschüssen, welche Führungsschienen für einen daran verfahrbaren, ein Lastaufnahmemittel tragenden Schlitten bilden, welcher mittels Oberrollen und Unterrollen an dem Schienenprofil gefuhrt ist, wobei der Abstand zwischen des Schlitten und der Unterrolle beim Uebergang von einer Führungsschiene auf die nächstfolgende größeren (kleineren) Querschnittes durch eine vom Schlittenseil (Lastseil) beaufschlagte Rollenverstellung selbstätig veränderbar ist und die Rollenverstellung aus einem Hebelgestänge besteht.The invention relates to an inclined elevator, in particular material and / 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, the distance between the carriage and the lower roller at the transition from a guide rail to the next larger (smaller) cross-section can be changed automatically by a roller adjustment acted upon by the slide rope (load rope) and the roller adjustment consists of a lever linkage.

Für den ausschließlichen Materialtransport ist ein Schrägaufzug bekannt geworden, an dessen Schlitten Ober- und Unterrollen angeordnet sind (DE-OS 35 41 836). Der bekannte Schrägaufzug weist mehrere Teleskopschüsse auf, welche aus leiterartig verbundenen Schienenprofilen gebildet sind. Die bekannten Schienenprofile sind etwa U-förmig ausgebildet, also "offene" Profile, welche im Bereich ihrer zueinander weisenden 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 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. In diesem Zusammenhang ist unter "besonderer Profilgebung" zu verstehen, daß die bekannte Schlittenführung nicht mehr ausreicht, wenn der "Sprung", d.h. also der Uebergang von einem Profil auf das nächstfolgende Profil zu groß wird. Dies kann beispielsweise bei den vorgenannten "offenen" Profilen gegeben sein, wenn die Flansche dieser offenen Profile sehr stark bemessen sind; insbesondere ist die Schlittenführung mit den aus dem Std. d. T. entnehmbaren Maßnahmen nicht mehr beherrschbar, wenn es sich um sogenannte "geschlossene", also kastenförmige Profile handelt.For the exclusive material transport, an inclined elevator has become known, on the carriage upper and lower rollers are arranged (DE-OS 35 41 836). The known inclined elevator has several telescopic sections, which are formed from ladder-like connected rail profiles. The known rail profiles are approximately U-shaped, that is to say "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 as long as the profile in the area of the upper and lower rollers as well as any side rollers (outer or inner rollers) is not given a special profile which significantly increases the transition from one profile to another . In this context, "special profiling" means that the known slide guidance is no longer sufficient if the "jump", ie the transition from one profile to the next profile, becomes too large. This can be the case, for example, with the aforementioned “open” profiles if the flanges of these open profiles are very large; in particular, the sled guide with the d. T. removable measures are no longer manageable when it comes to so-called "closed", ie box-shaped profiles.

Bei der Gestaltung von Schrägaufzügen insbesondere für den Personen- oder ggf. kombinierten Personen- und Materialtransport wird aus Sicherheitsgründen geschlossenen Hohlprofilen der Vorzug gegeben, welche teleskopartig ineinandergesteckt und - mit Ausnahme des letzten, untersten Teleskopschusses - nur im Bereich ihrer oberen Enden durch eine Quertraverse verbunden sind. Bei einem derartigen Schrägaufzug können die Ober- bzw. Unterrollen nur an den Ober- bzw. Unterseiten dieser Profile geführt werden, wobei vom untersten Profil bis zum obersten Profil eine erhebliche Durchmesserveränderung gegeben ist. Demgemäß ist nach Maßgabe der älteren deutschen Patentanmeldung P 36 34. 702.7 am Schlitten eine den Rollenabstand zwischen Oberrolle und Unterrolle beim Uebergang von einer Scheine größeren (kleineren) Querschnitts auf eine Scheine kleineren (größeren) Querschnitts verringernde (vergrößernde) Rollenverstellung angeordnet. Diese Rollenverstellung sieht im einzelnen vor, daß bei unveränderlichem Abstand der Oberrolle(n) zum Schlittengrundrahmen eine automatische Anpassung der Unterrolle(n) sowie der Seitenrolle zum jeweils überfahrenen Schienenprofil erfolgt. Unterrolle(n) und Seitenrolle werden gemeinsam mittels einer Gasfeder über ein Parallelogrammgelenk verstellt.When designing inclined elevators, in particular for the transport of people or, if necessary, combined transport of people and materials, preference is given to closed hollow profiles for safety reasons, which are telescopically nested and - with the exception of the last, lowest telescopic section - only connected in the area of their upper ends by a crossbar are. With such an inclined elevator, the top and bottom rollers can only be guided on the top and bottom sides of these profiles, with a considerable change in diameter from the bottom profile to the top profile. Accordingly, in accordance with the older German patent application P 36 34. 702.7, the roller spacing between the upper roller and lower roller at the transition from a bill of larger (smaller) cross-section to a bill of smaller (larger) cross-section is arranged (increasing) roller adjustment. This roller adjustment provides in particular that, if the distance between the upper roller (s) and the slide base frame remains unchanged, the lower roller (s) and the side roller are automatically adapted to the respective rail profile run over. The lower roller (s) and side roller are adjusted together using a gas spring via a parallelogram joint.

Die Erfindung geht von einem Schrägaufzug aus, wie er durch die GB-A 21 79 915 bekannt geworden ist. Bei dem vorbekannten Schrägaufzug ist ein vom Schlittenseil betätigtes Hebelgestänge vorgesehen, welches auf die Unterrollen des Schlittens wirkt und die Unterrolen in Abhängigkeit vom Zug des Lastseiles selbstätig gegen die Unterkante der Führungsschienen preßt. Dabei wird ausschließlich der Abstand der Unterrollen zueinander verstellt; eine Verstellung der Oberrollen gegenüber dem Schlittenrahmen erfolgt nicht. Seitenrollen, wie sie bei hochbelasteten Schrägaufzügen heute erforderlich sind, sind nicht vorgesehen. Ausgehend von dem Std. d. T. nach GB-A 21 79 915 ist es Aufgabe der Erfindung, die Rollenverstellung zu verbessern; dabei soll berücksichtigt werden, daß der Abstand zwischen Oberrolle und Unterrolle einerseits sowie der Abstand der gegenüberliegenden Seitenrollen andererseits unabhängig voneinander verstelbar ist. Weiter wird mit der Erfindung angestrebt, mit Bezug auf die Abstandsveränderung zwischen Oberrolle und Unterrolle den Andruck der Rollen unabhängig vom Profildurchmesser gleichmäßig zu gestalten, d.h. die Andruckkraft von Oberrolle und Unterrolle soll gleich groß sein, unabhängig davon, ob die vorgenannten Rollen dem Profil größten Querschnitts oder dem Profil kleinsten Querschnitts anliegen. Insbesondere soll mit der vorliegenden Erfindung erreicht werden, daß sowohl Oberrolle als auch Unterrolle lastabhängig eine Bewegung relativ zum Schlitten ausführen.The invention is based on an inclined elevator, as is known from GB-A 21 79 915. In the known inclined elevator a lever linkage operated by the sled rope is provided, which acts on the lower rollers of the sled and the lower rollers automatically depending on the pull of the load rope against the Bottom edge of the guide rails presses. Only the distance between the lower rollers is adjusted to each other; the upper rollers are not adjusted relative to the slide frame. Side rollers, such as are required today for high-load inclined elevators, are not provided. Starting from the std. T. according to GB-A 21 79 915, it is an object of the invention to improve the roller adjustment; it should be taken into account that the distance between the top roller and the bottom roller on the one hand and the distance between the opposite side rollers on the other hand can be adjusted independently of one another. Furthermore, the invention aims to make the pressure of the rollers uniform regardless of the profile diameter with respect to the change in distance between the upper roller and lower roller, ie the pressing force of the upper roller and lower roller should be the same, regardless of whether the aforementioned rollers have the largest cross-sectional profile or the profile with the smallest cross-section. In particular, the aim of the present invention is to ensure that both the upper roller and lower roller perform a movement relative to the carriage depending on the load.

Die Erfindung löst die gestellte Aufgabe durch die Lehre nach Anspruch 1. Hiernach übt das Schlittenseil über ein entsprechendes Hebelgestänge einen Andruck auf die Oberrolle und die Unterrolle aus (wobei in bekannter Weise jeweils vordere und hintere Rollenpaare zur Anwendung kommen). Der Zug des Lastseiles wird über das Hebelgestänge auf einen vorderen und einen hinteren Lagerbalken übertragen, an dessen freien Enden die die Doppelrollen tragenden Schwingen angeordnet sind. Der für die Anpassung an das nächstfolgende Profil größeren oder kleineren Querschnitts erforderliche Schwenkweg der jeweiligen Rollen (Oberrollen oder Unterrollen) ist nach der hier vorliegenden Erfindung auf Oberrolle und Unterrolle aufgeteilt - während beim Std. d. T. nach GB-A 21 79 915 der gesamte Schwenkweg ausschließlich mittels der Unterrollen durchgeführt werden muß. Es ist ersichtlich, daß sich der Zug des Schlittenseiles (Lastseiles) über das Hebelgestänge auf die Unterrolle bzw. Oberrolle überträgt, d.h. der Anpreßdruck dieser Rollen bleibt gleich, unabhängig davon, ob der Schlitten an einem Profil großen oder kleinen Querschnitts verfährt. Bekanntlich muß die Rollenführung um so exakter sein, je stärker der Schlitten belastet ist, weil bei relativ steil stehendem Schrägaufzug auf den Schlitten ein starkes Kippmoment entgegen der Zugrichtung des Lastseiles ausgeübt wird. Hier liegt ein besonderer Vorteil darin, daß eine unmittelbare Beziehung zwischen der Belastung des Schlittens (und damit zwangsläufig der Belastung des Lastseiles) und dem Andruck der Ober- bzw. Unterrolle gegeben ist, d.h. je stärker der Schlitten belastet ist, desto höher ist der Andruck der Ober- bzw. Unterrolle und damit desto sicherer ist die Führung des Schlittens am Schienenprofil des Schrägaufzuges - wieder unabhängig davon, ob es sich um ein Profil größeren oder kleineren Querschnittes handelt. Dies gilt - wie vorerwähnt - für die Führung der Ober- bzw. Unterrrolle am Schlitten; weniger für die Seitenrollen, weil diese durch die zusätzliche Belastung nur geringfügig stärker belastet werden. Es ist deshalb von besonderem Vorteil, daß sich der Zug des Schlittenseiles ausschließlich auf den Andruck der Ober- und Unterrolle - auswirkt, nicht jedoch zusätzlich auf den Andruck der Seitenrolle. Insofern liegt eine vorteilhaftere Ausgestaltung der Grundüberlegung nach der Anmeldung P 36 34 702.7 vor.The invention solves the stated problem by the teaching according to claim 1. According to this, the slide rope exerts pressure on the upper roller and the lower roller via a corresponding lever linkage (front and rear pairs of rollers being used in a known manner). The pull of the load rope is transmitted via the lever linkage to a front and a rear bearing beam, at the free ends of which the rockers carrying the double rollers are arranged. The one for customization to the next following profile of larger or smaller cross-section required swivel path of the respective rollers (top rollers or bottom rollers) is divided according to the present invention between top roller and bottom roller - while at d. T. according to GB-A 21 79 915 the entire swivel path must be carried out exclusively by means of the lower rollers. It can be seen that the pull of the sled rope (load rope) is transmitted via the lever linkage to the lower roller or upper roller, ie the contact pressure of these rollers remains the same, regardless of whether the sled travels on a profile of large or small cross-section. As is known, the roller guide must be more precise the more heavily the carriage is loaded, because with a relatively steep inclined elevator, a strong tilting moment is exerted on the carriage against the direction of pull of the load rope. A particular advantage here is that there is a direct relationship between the load on the slide (and thus inevitably the load on the load rope) and the pressure on the top or bottom roller, ie the more the slide is loaded, the higher the pressure the upper or lower roller and thus the safer it is to guide the slide on the rail profile of the inclined elevator - again regardless of whether it is a profile with a larger or smaller cross-section. As mentioned above, this applies to the guidance of the upper or lower roller on the slide; less for the side rollers, because these are only slightly more stressed by the additional load. It is therefore of particular advantage that the pull of the sled rope is based solely on the pressure of the top and bottom roller - affects, but not additionally on the pressure of the side roller. In this respect, there is a more advantageous embodiment of the basic consideration after registration P 36 34 702.7.

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

Die Erfindung ist gemäß Anspruch 4 im einzelnen so verwirklicht, daß das Lastseil an einer drehbaren Zugachse angreift, die ihrerseits einen drehfest mit ihr verbundenen Hebel aufweist, an dem drehbar eine Zuglasche angeordnet ist, die mit ihrem anderen (unteren) Ende drehbar mit einem Waagebalken verbunden ist, welcher über zwischengeschaltete weitere Zuglaschen die unteren Enden des vorderen und hinteren Lagerbalkens miteinander verbindet. Die freien Enden des Waagebalkens sind somit über eine weitere Zuglasche drehbar mit dem unteren Ende des vorderen Lagerbalkens bzw. des hinteren Lagerbalkens drehbar verbunden. Dies bedeutet, daß bei Belastung des Lastseiles die unteren Enden des Lagerbalkens gegeneinander gezogen werden, d.h., der Rollenabstand der Unterrollen verringert sich bei abnehmendem Profilquerschnitt, während sich der Rollenabstand der Oberollen gleichzeitig vergrößert. Dies hat zur Folge, daß die die Last tragenden Oberrollen mit zunehmend kleinerem Profilquerschnitt mit größerem Abstand dem Profil von oben her aufliegen (Anspruch 6). Hierzu ist es zweckmäßig, den Lagerbalken im Bereich seiner Längsmitte an einem Längsträger des Schlittengrundrahmens drehbar zu lagern (Anspruch 5).The invention is implemented according to claim 4 in detail so that the load rope engages a rotatable pull axis, which in turn has a non-rotatably connected lever on which a pull tab is rotatably arranged, the other (lower) end of which is rotatable with a balance beam is connected, which connects the lower ends of the front and rear bearing beams to each other via intermediate pull tabs. The free ends of the balance beam are thus rotatably connected to the lower end of the front bearing beam or the rear bearing beam via a further pull tab. This means that when the load rope is loaded, the lower ends of the bearing beam are pulled towards each other, ie the roller spacing of the lower rollers decreases as the profile cross section decreases, while the roller spacing of the upper rollers increases at the same time. This has the consequence that the load-bearing top rollers with an increasingly smaller profile cross section lie at a greater distance from the profile from above (claim 6). For this purpose, it is expedient to rotatably support the bearing beam in the region of its longitudinal center on a longitudinal member of the slide base frame (claim 5).

Wie vorerwähnt, wirkt das Lastseil hinsichtlich der Rollenverstellung ausschließlich auf die Oberrolle bzw. die Unterrolle; Anspruch 8 vermittelt sinngemäß die Lehre, die Seitenrollen mittels einer Gasfeder und eines entsprechenden Hebelgestänges unabhängig von der Zugkraft des Lastseiles gegen die Außenflächen des Schienenprofils selbstätig elastisch anzupressen.As mentioned above, the load rope only acts on the top roller or the bottom roller with regard to the roller adjustment; Claim 8 conveys the teaching analogously, to press the side rollers by means of a gas spring and a corresponding lever linkage independently of the tensile force of the load rope against the outer surfaces of the rail profile automatically.

Bei einem Bruch des Lastseiles ist keine definierte Führung der Ober- bzw. Unterrolle am Schienenprofil mehr gegeben; Anspruch 9 vermittelt sinngemäß die Lehre, die in bekannter Weise verwendete Exzenterbremse zwischen zwei Längsträgern des Schlittengrundrahmens so anzuordnen, daß sie mittels einer Gasfeder beaufschlagbar ist, welche über ein zwischengeschaltetes Zugseil auf die drehfest mit der Zugachse verbundene Exzenterbremse ständig ein entgegen der Zugrichtung des Lastseiles gerichtetes Moment ausübt.If the load rope breaks, there is no longer any defined guidance of the upper or lower roller on the rail profile; Claim 9 conveys the doctrine of arranging the eccentric brake used in a known manner between two longitudinal members of the slide base frame so that it can be acted upon by a gas spring, which is continuously directed against the direction of pull of the load rope via an intermediate pull rope on the eccentric brake non-rotatably connected to the pull axis Moment.

In der Fig. 2 ist in der Seitenansicht der allgemein mit 10 dargestellte Schlitten mit dem strichpunktiert angedeuteten Lastaufnahmemittel 9 dargestellt. Der Schlitten 10 weist einen Schlittengrundrahmen 21 auf (s. Fig. 3) der aus mehreren Längsträgern 27, 33 und 38 sowie Querträgern 39 und 40 und Vertikalstützen 41 gebildet ist. Die allgemein mit 14 bezeichnete Rollenverstellung erfolgt über ein Hebelgestänge 16, das im folgenden erläutert wird:
Die in Pfeilrichtung 18 wirkende Zugkraft der beiden Lastseile 15 und 15' wird über die mit 37 bezeichneten Zughebel, welche drehfest mit der Zugachse 22 verbunden sind, auf die Zugachse 22 übertragen. Die Drehbewegung der Zugachse 22 wird weiter über den ebenfalls drehfest mit der Zugachse 22 verbundenen Hebel 23 auf die Doppellasche 24 übertragen (die Bewegung des Hebelgestänges ist in der Fig. 2 durch entsprechende Pfeile verdeutlicht); der Zug in der Doppellasche 24 überträgt sich auf den Waagebalken 25, an dem drehbar die mit 26 bezeichneten Doppellaschen angeordnet sind. Das freie Ende der Doppellaschen 26 ist über das Lager 42 mit dem unteren freien Ende jeweils eines vorderen und eines hinteren Lagerbalkens 17 verbunden, so daß diese Enden der Lagerbalken 17 bei Belastung des Lastseiles 15, 15' gegeneinander gezogen werden. Da am unteren und am oberen Ende jedes der beiden Lagerbalken 17, 17' im Drehlager 19 die Doppelrollen (Oberrollen 11 und Unterrollen 12) über eine Schwinge 20 gelagert sind, werden Oberrollen 11 und Unterrollen 12 bei Belastung der Lastseile 15 und 15' gegeneinander und damit gegen das Schienenprofil 13 gezogen, so daß sich, wie in der Fig. 2 dargestellt, an der Schiene 4 der Abstand a einstellt.2 is a side view of the generally 10th shown carriage with the load-carrying means 9 indicated by dash-dotted lines. The carriage 10 has a carriage base frame 21 (see FIG. 3) which is formed from a plurality of longitudinal members 27, 33 and 38, as well as cross members 39 and 40 and vertical supports 41. The roller adjustment, generally designated 14, takes place via a lever linkage 16, which is explained in the following:
The tensile force of the two load cables 15 and 15 'acting in the direction of the arrow 18 is transmitted to the tension axle 22 via the tension levers 37, which are connected in a rotationally fixed manner to the tension axle 22. The rotational movement of the pull axis 22 is further transmitted to the double bracket 24 via the lever 23, which is also connected in a rotationally fixed manner to the pull axis 22 (the movement of the lever linkage is illustrated in FIG. 2 by corresponding arrows); the train in the double bracket 24 is transferred to the balance beam 25, on which the double brackets designated 26 are rotatably arranged. The free end of the double brackets 26 is connected via the bearing 42 to the lower free end of a front and a rear bearing beam 17, so that these ends of the bearing beams 17 are pulled towards one another when the load rope 15, 15 'is loaded. Since the double rollers (upper rollers 11 and lower rollers 12) are mounted on a rocker arm 20 at the lower and upper ends of each of the two bearing beams 17, 17 'in the pivot bearing 19, upper rollers 11 and lower rollers 12 are loaded against each other when the load cables 15 and 15' are loaded thus pulled against the rail profile 13, so that, as shown in FIG. 2, the distance a is set on the rail 4.

Die Lagerbalken 17 und 17' sind im Bereich ihrer Längsmitte in Lagern 28 eines Längsträgers 27 des Schlittengrundrahmens 21 im Abstand c gelagert. Es ist ersichtlich, daß bei geringer werdendem Abstand a, d.h. bei zunehmend kleinerem Profilquerschnitt der Abstand b zwischen den Oberrollen 11 größer und der Abstand b' zwischen den Unterrollen 12 geringer wird.The bearing beams 17 and 17 'are mounted in the area of their longitudinal center in bearings 28 of a longitudinal member 27 of the slide base frame 21 at a distance c. It can be seen that as the distance a, i.e. with an increasingly smaller profile cross section, the distance b between the upper rollers 11 becomes larger and the distance b 'between the lower rollers 12 becomes smaller.

Aus der Fig. 4 ist entnehmbar, daß die am Lagerbalken 17 bzw. 17' angeordneten Drehlager 19 vom Lagerbalken 17 bzw. 17' in Richtung auf die Schlittenlängsmitte vorspringen, so daß die in den Schwingen 20 gelagerten Oberrollen 11 bzw. Unterrollen 12 dem Schienenprofil 13 einwandfrei anliegen.From Fig. 4 it can be seen that the pivot bearing 19 arranged on the bearing beam 17 or 17 'project from the bearing beam 17 or 17' in the direction of the longitudinal center of the slide, so that the upper rollers 11 and lower rollers 12 mounted in the rockers 20 the rail profile 13 fit perfectly.

Es versteht sich, daß das vorbeschriebene Hebelgestänge 16 der Rollenverstellung 14 symmetrisch zur Schlittenlängsmitte angeordnet ist.It is understood that the above-described lever linkage 16 of the roller adjustment 14 is arranged symmetrically to the center of the longitudinal slide.

Das aus den Fig. 3 und 4B erkennbare Hebelgestänge 31 für die Verstellung der Seitenrollen 29 wird wie folgt erläutert:
Am Querträger 39 des Schlittengrundrahmens 21 ist im Drehlager 43 eine Gasfeder 30 angeschlossen, welche auf einem mit 44 bezeichneten zweiarmigen Hebel wirkt, der über eine Stützkonsole 45 am Querträger 39 abgestützt ist. An den freien Enden des zweiarmigen Hebels 44 angeordnete Zugstangen 46 und 47 übertragen den Druck der Gasfeder 30 über Hebel 48 und mit diesen drehfest verbundene Schwenkachsen 49 auf Winkelhebel 50, an denen die Seitenrollen 29 gelagert sind, so daß sie mittels der Gasfeder 30 gegen die Außenfläche 32 des Schienenprofils im Sinne einer Abstandsveränderung des Abstandes d anpreßbar sind.The lever linkage 31 recognizable from FIGS. 3 and 4B for the adjustment of the side rollers 29 is explained as follows:
On the cross member 39 of the slide base frame 21, a gas spring 30 is connected in the pivot bearing 43, which acts on a two-armed lever, designated 44, which is supported on the cross member 39 via a support bracket 45. Drawbars 46 and 47 arranged on the free ends of the two-armed lever 44 transmit the pressure of the gas spring 30 via levers 48 and pivot axes 49 connected to them in a rotationally fixed manner to angle levers 50 on which the side rollers 29 are mounted so that they can be pressed by means of the gas spring 30 against the outer surface 32 of the rail profile in the sense of a change in the distance of the distance d.

In der Fig. 3 ist zwischen zwei Längsträgern 33 des Schlittengrundrahmens 21 eine in der dargestellten Pfeilrichtung beaufschlagte Gasfeder 34 dargestellt, die mittels eines Zugseiles 35 einen ständigen Zug auf die Exzenterbremse 36 ausübt. Zu diesem Zweck umschlingt das Zugseil 35 mehrfach die Zugachse 22 und ist an dieser festgelegt. Beim Bruch des Lastseiles 15, 15' fällt somit aktiv die Exzenterbremse ein; die Unterrollen 12 werden dabei sofort gegen die Unterseite des Schienenprofils gepreßt und das Schienenprofil zwischen Exzenterbremse 36 und Unterrolle 12 reibungsschlüssig gehalten.In Fig. 3 between two longitudinal members 33 of the slide base frame 21, a gas spring 34 is shown acted on in the direction of the arrow, which exerts a constant tension on the eccentric brake 36 by means of a traction cable 35. For this purpose, the traction cable 35 wraps around the traction axis 22 several times and is fixed to it. When the load rope 15, 15 'breaks, the eccentric brake is actively applied; the lower rollers 12 are immediately pressed against the underside of the rail profile and the rail profile between the eccentric brake 36 and the lower roller 12 is held frictionally.
