Description

Die Erfindung betrifft eine Räum- und Förderkette zum Transport von Bettungsschotter eines Gleises, bestehend aus gelenkig miteinander verbundenen und in einem Fördertrog geführten Kettengliedern und an diesen befestigten Kratzerschaufeln, die am vom Kettenglied distanzierten Ende über einen Rand der Kratzerschaufel fingerförmig vorragende Kratzerfinger aufweisen.The invention relates to a clearing and conveyor chain for the transport of ballast ballast of a track, consisting of articulated and chain links guided in a conveyor trough and fastened to them Scraper blades above the end distanced from the chain link an edge of the scraper blade protruding finger-shaped Have scratch fingers.

Räum- und Förderketten dieser Art werden seit langem insbesondere bei Gleisbettungs-Reinigungsmaschinen mit großem praktischen Erfolg verwendet. Die Kette ist in zwei an gegenüberliegenden Seiten des Maschinenrahmens angelenkten Kettenführungs-Längsbahnen und einer quer unter dem Gleisrost durchführbaren Kettenführungs-Querbahn über Umlenkrollen in etwa Dreieck- bzw. Polygonform endlos geführt und mit Hilfe eines Antriebes in Rotation versetzbar. Im Bereich der Kettenführungs-Querbahn kommen die Kratzerschaufeln mitsamt den daran befestigten Kratzerfingern mit dem Schotterbett in Eingriff und befördern dabei Schottersteine in Richtung zur Bettungsflanke und von dort über die als Fördertrog ausgebildete Kettenführungs-Längsbahn zu einer am Maschinenrahmen angeordneten Siebanlage. Die Kratzerfinger sind aus verschleißfestem Material gebildet und lösbar mit den Kratzerschaufeln verbunden. Damit können die Kratzerfinger nach fortgeschrittenem Verschleiß ausgetauscht werden. Derartige Kratzerfinger sind bereits durch die AT 349 051 B bekannt.Clearing and conveyor chains of this type have long been used in particular Track bed cleaning machines used with great practical success. The chain is in two on opposite sides of the machine frame articulated chain guide longitudinal tracks and one across the Track grating feasible chain guide cross track over pulleys in such as a triangular or polygonal shape and with the help of a drive rotatable. Come in the area of the chain guide cross track the scraper blades together with the attached scratch fingers with the Ballast bed in engagement and thereby convey ballast stones towards Bed flank and from there via the chain guide longitudinal track designed as a conveyor trough to a screening plant arranged on the machine frame. The scratch fingers are made of wear-resistant material and can be detached connected to the scraper blades. So that the scratch fingers after advanced wear can be replaced. Such scratch fingers are already known from AT 349 051 B.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Räum- und Förderkette der gattungsgemäßen Art, mit der bei relativ geringem konstruktivem Aufwand ein rascher und einfacher Austausch von abgenutzten Kratzerfingern möglich ist und ein die Transport- und Förderleistung reduzierendes Durchfallen bzw. Verklemmen von Schottersteinen zwischen den Kratzerfingern zuverlässig ausgeschlossen ist.The object of the present invention is now to create a Clearing and conveyor chain of the generic type, with the relatively small constructive effort a quick and easy exchange of worn out Scratch fingers is possible and the transport and conveying performance reducing falling through or jamming of gravel stones between the scratch fingers is reliably excluded.

Diese Aufgabe wird mit einer Räum- und Förderkette der gattungsgemäßen Art dadurch gelöst, daß die Kratzerfinger zweiteilig ausgebildet sind, wobei ein erster Teil durch einen mit der Kratzer schaufel verbundenen, fingerförmig abstehenden Mitnehmer und ein zweiter Teil durch eine auf den Mitnehmer aufsteckbare und durch ein Befestigungsmittel lösbar verbundene Schutzkappe gebildet ist und wobeizwischen den Kratzerfingern jeweils ein fingerförmig über den Rand der Kratzerschaufel vorragendes Schaufelelement vorgesehen ist. This task is carried out with a clearing and conveyor chain of the generic type Art solved in that the scratch fingers are formed in two parts, a first part by a finger-like protruding part connected to the scraper Carrier and a second part by an attachable to the carrier and is formed by a fastener releasably connected to a protective cap, with a finger-shaped between each of the scratch fingers Blade element projecting over the edge of the scraper blade is provided is.

Diese zweiteilige Ausbildung begünstigt eine relativ breite, senkrecht zur Förderrichtung verlaufende, den Schotter transportierende Arbeitsfläche der Schutzkappen, wodurch der zwischen den benachbarten Kratzerfingern befindliche Raum relativ klein ausgebildet werden kann. Damit läßt sich eine unerwünschte Reduzierung der Transportleistung infolge von zwischen den Kratzerfingern durchfallenden Schottersteinen zuverlässig ausschließen. Andererseits kann aber durch eine in bezug auf die Förderrichtung schmale Ausbildung der Kratzerfinger eine optimale Reißwirkung für ein rasches Losreißen auch von verkrusteten Schottersteinen beibehalten werden. Außerdem wird mit der Aufsteckbarkeit der Schutzkappen und deren - infolge der breiteren Ausbildung - geringeren Anzahl die Umrüstzeit für die Erneuerung wesentlich vereinfacht. Zusätzlich ist mit der Aufsteckbarkeit eine einfache satte Verbindung zwischen Mitnehmer und Schutzkappe sichergestellt, wodurch die stoßförmig einwirkenden Kräfte beim Losreißen der Schottersteine aus der Gleisbettung problemlos aufgenommen werden können. Von besonderem Vorteil ist außerdem noch, daß der als Fixierungsorgan wirksame Mitnehmer zur Gänze durch die Schutzkappe abgedeckt wird, so daß selbst nach längerer Einsatzdauer der Mitnehmer selbst in keiner Weise einem Verschleiß unterliegt und ein problemloser Austausch der Schutzkappe gewährleistet bleibt.This two-part training favors a relatively wide, perpendicular to Direction of conveyance, working surface transporting the ballast Protective caps, which means that between the adjacent scratch fingers Space can be made relatively small. So that one undesirable reduction in transport performance due to between the Exclude scratching fingers from falling gravel stones. On the other hand but can be narrow with respect to the direction of conveyance Training of the scratch fingers an optimal tear effect for a quick tear off can also be retained from encrusted gravel stones. Furthermore comes with the attachability of the protective caps and their - as a result of broader training - lower number of changeover times for renewal much simplified. In addition, the pluggability is an easy one ensures a tight connection between the driver and the protective cap, thereby the impact forces when the gravel stones are torn loose can be easily taken from the track bed. Of special Another advantage is that the driver acting as a fixing member is completely covered by the protective cap, so that even after a long period of use, the driver itself does not show any wear subject and ensures a problem-free replacement of the protective cap remains.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention result from the Subclaims.

Im folgenden wird die Erfindung an Hand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben.In the following the invention is illustrated by means of one in the drawing Embodiment described in more detail.

Es zeigen:

  • Fig. 1 eine Draufsicht auf eine Räum- und Förderkette, von der ausschnittsweise lediglich zwei Kratzerschaufeln dargestellt sind,
  • Fig. 2 eine Ansicht einer Kratzerschaufel in Förderrichtung gemäß Pfeil II in Fig. 1,
  • Fig. 3 einen vergrößerten Querschnitt durch einen fingerförmigen Mitnehmer gemäß der Schnittlinie III in Fig. 2, wobei jedoch eine den Mitnehmer umfassende Schutzkappe weggelassen ist, und
  • Fig. 4 eine vergrößerte Ansicht einer Schutzkappe.
    • Show it:
  • 1 is a plan view of a broaching and conveyor chain, of which only two scraper blades are shown,
  • 2 is a view of a scraper blade in the conveying direction according to arrow II in Fig. 1,
  • 3 shows an enlarged cross section through a finger-shaped driver according to section line III in FIG. 2, but with a protective cap surrounding the driver being omitted, and
  • Fig. 4 is an enlarged view of a protective cap.

    • Eine Räum- und Förderkette 1 setzt sich aus einer Vielzahl von Kettengliedern 2 zusammen, von denen jedes zweite mit einer Kratzerschaufel 3 zum Transport von Bettungsschotter verbunden ist. Die Räum- und Förderkette 1 liegt auf einer Gleit- und Förderebene 4 eines Fördertroges 5 auf. Jede Kratzerschaufel 3 ist - wie in Fig. 2 ersichtlich - mit über einen Rand 6 fingerförmig vorragenden Kratzerfingern 7 ausgestattet.A clearing and conveyor chain 1 consists of a large number of chain links 2 together, each second with a scraper 3 to Transport of ballast ballast is connected. The clearance and conveyor chain 1 lies on a sliding and conveying plane 4 of a conveying trough 5. Any scraper 3 is - as can be seen in Fig. 2 - with an edge 6 finger-shaped protruding scratch fingers 7 equipped.

    Jeder dieser insgesamt drei Kratzerfinger 7 ist zweiteilig ausgebildet, wobei ein erster Teil durch einen mit der Kratzerschaufel 3 verbundenen, fingerförmig über den genannten Rand 6 abstehenden Mitnehmer 8 und ein zweiter Teil durch eine auf den Mitnehmer 8 aufsteckbare Schutzkappe 9 gebildet ist. Diese den Mitnehmer 8 zur Gänze umschließende Schutzkappe 9 ist aus verschleißfestem Material gebildet und durch ein Befestigungsmittel 10 lösbar mit dem Mitnehmer 8 verbunden. Das als Schwerspannstift 11 ausgebildete Befestigungsmittel 10 ist in einem an den Rand 6 der Kratzerschaufel 3 angrenzenden Endbereich 12 (siehe Fig. 3) des Mitnehmers 8 positioniert.Each of these three scratch fingers 7 is formed in two parts, wherein a first part by a finger-shaped connected to the scraper blade 3 driver 8 projecting over said edge 6 and a second one Part is formed by a protective cap 9 which can be plugged onto the driver 8 is. This completely enclosing the driver 8 protective cap 9 is made wear-resistant material formed and releasable by a fastener 10 connected to the driver 8. The trained as a heavy duty pin 11 Fastening means 10 is in a on the edge 6 of the scraper blade 3 adjacent end region 12 (see FIG. 3) of the driver 8 positioned.

    Zwischen den Kratzerfingern 7 ist jeweils ein fingerförmig über den Rand 6 der Kratzerschaufel 3 vorragendes, einem Mitnehmer 8 ähnliches Schaufelelement 13 vorgesehen, das nicht mit einer Schutzkappe abgedeckt wird. Damit ist ein die Transport- und Förderleistung reduzierendes Durchfallen bzw. Verklemmen von Schottersteinen zwischen den Kratzerfingern 7 zuverlässig ausgeschlossen. Da diese Schaufelelemente 13 kürzer als die benachbarten Kratzerfinger 7 sind, wird die Abnützung entsprechend reduziert. Between each of the scratch fingers 7 is a finger-shaped over the edge 6 the scraper blade 3 projecting blade element similar to a driver 8 13 provided that is not covered with a protective cap. This means falling through which reduces transport and conveying performance or jamming of gravel stones between the scratch fingers 7 reliably locked out. Since these blade elements 13 are shorter than the neighboring ones Scratch fingers 7, the wear is reduced accordingly.

    Jede Kratzerschaufel 3 weist eine bezüglich der Förderrichtung (Pfeil 14 in Fig. 1) vordere Arbeitsebene 15 zum Transport des Schotters auf. Wie in Fig. 1 ersichtlich, ist das eine Längsachse 16 aufweisende Befestigungsmittel 10 im Winkel zur Arbeitsebene 15 der Kratzerschaufel 3 angeordnet. Eine bezüglich der Förderrichtung vordere Arbeitsfläche 17 der Schutzkappe 9, die der Gleit- und Förderebene 4 unmittelbar benachbart ist, ist mit einer Verschleißplatte 18 aus besonders verschleißfestem Material verbunden. Wie in Fig. 1 ersichtlich, sind die Schutzkappen 9 mit ihren Arbeitsflächen 17 in einer gemeinsamen Ebene 19 verlaufend angeordnet.Each scraper blade 3 has one with respect to the conveying direction (arrow 14 in Fig. 1) front working level 15 for transporting the ballast. As in 1, the fastener has a longitudinal axis 16 10 arranged at an angle to the working plane 15 of the scraper blade 3. A with respect to the conveying direction, the front working surface 17 of the protective cap 9, which is immediately adjacent to the sliding and conveying plane 4 is with a Wear plate 18 connected from a particularly wear-resistant material. As can be seen in Fig. 1, the protective caps 9 with their work surfaces 17 arranged in a common plane 19.

    Wie insbesondere in Fig. 3 und 4 ersichtlich, ist der Schwerspannstift 11 durch eine Bohrung 20 des Mitnehmers 8 und zwei einander gegenüberliegende Bohrungen 21 der Schutzkappe 9 (siehe Fig. 4) hindurchgeführt. Durch eine pyramidenstumpfförmige Ausbildung des Mitnehmers 8 ist ein spielfreier und fester Sitz der Schutzkappe gewährleistet. Wie in Fig. 4 ersichtlich, ist die Arbeitsfläche 17, die in diesem Fall mit der Verschleißplatte 18 verbunden ist, sowie eine der Arbeitsfläche 17 gegenüberliegende Fläche 22 der Schutzkappe 9 unter Bildung eines trapezförmigen Querschnittes im Winkel zu einer senkrecht zur Längsrichtung bzw. Längsachse 16 des Befestigungsmittels 10 verlaufenden Symmetrieebene 23 des Mitnehmers 8 angeordnet.As can be seen in particular in FIGS. 3 and 4, the heavy-duty spring pin 11 through a bore 20 of the driver 8 and two opposite one another Bores 21 of the protective cap 9 (see Fig. 4) passed through. By a truncated pyramid-shaped design of the driver 8 is a backlash-free and tight fit of the protective cap is guaranteed. As can be seen in Fig. 4, is the work surface 17, in this case with the wear plate 18 is connected, and a surface opposite the work surface 17 22 of the protective cap 9 to form a trapezoidal cross section in Angle to a perpendicular to the longitudinal direction or longitudinal axis 16 of the fastener 10 extending plane of symmetry 23 of the driver 8 arranged.
