Description

Die Erfindung bezieht sich auf eine Räum- und Förderkette für eine Gleisbaumaschine zum Transport von Bettungsschotter eines Gleises, mit gegebenenfalls über Zwischenglieder gelenkig miteinander verbundenen Räumschaufeln aufweisenden Kettengliedern, die im Bereich des vom Kettenglied auskragenden Schaufelendes vorzugsweise mit über den Schaufelrand vorragenden Kratzerfingern ausgestattet sind ( EP 0 737 779 A1 ).The invention relates to a clearing and conveyor chain for a track construction machine for the transport of ballast of ballast, with possibly interconnected articulated buckets having intermediate links chain links which are preferably equipped in the region of projecting from the chain link blade end with projecting beyond the blade edge scraper fingers ( EP 0 737 779 A1 ).

In Schottergleisen unterliegt der Schotter einer Anreicherung durch Feinanteile, die durch den Abrieb und den Kantenbruch des belasteten Schotters im Zugbetrieb anfallen. Zum anderen werden Feinanteile durch ein Aufsteigen von Partikel aus dem Untergrund, durch den Transport z.B. von Kohle und Erzen, durch Anflug aus der Umgebung oder durch organisches Material eingebracht.In gravel tracks the gravel is subject to enrichment by fines, which are caused by the abrasion and the edge breakage of the loaded ballast in train operation. On the other hand, fines are caused by an increase of particles from the ground, by transporting e.g. of coal and ores, brought in by approach from the environment or by organic material.

Übersteigt der Massenanteil der Feinstoffe (<12mm) 30% der Gesamtmasse des Bettungsschotters wird der Schotter gereinigt, da sonst die Entwässerung und damit die Tragfähigkeit des Untergrundes nicht mehr gesichert wären. Mangelhafte Entwässerung hat zur Folge, dass allenfalls vorhandene Holzschwellen ständig in feuchter Umgebung liegen und so schnell morsch werden und an Haltbarkeit verlieren.If the mass fraction of fines (<12 mm) exceeds 30% of the total mass of the ballast, the ballast is cleaned, otherwise the drainage and thus the load bearing capacity of the substrate would no longer be guaranteed. Inadequate drainage means that any existing wooden sleepers are constantly in a moist environment and so quickly become rotten and lose their durability.

Die Reinigung des Schotters erfolgt mit Hilfe von Gleisbettreinigungsmaschinen. Dazu wird der Gleisrost unterhalb der Maschine angehoben und darunter eine Kettenführung, ein Kettenführungsbalken, eingebaut, in der die umlaufende Reinigungskette geführt ist. Die Kette umfasst Räumschaufeln welche untereinander über Zwischenglieder gelenkig verbunden sind. Die Räumschaufeln mit den Zwischengliedern gleiten in Kettenführungen auf austauschbaren Verschleißblechen. Angetrieben wird die Kette üblicherweise hydraulisch über einen so genannten Turasantrieb. Der Schotter wird mit Hilfe der Räumschaufeln aus dem Schotterbett ausgehoben, nach oben in die Gleisbettreinigungsmaschinen befördert und fällt dort auf ein Förderband welches das verunreinigte Material auf ein mehrlagiges Rüttelsieb schüttet. Das Feinmaterial wird vom Überkorn (>80mm) abgeschieden, zu mitgeführten Verladewagen befördert und dort bis zu seiner Entsorgung gespeichert. Der gereinigte Schotter wird zur Aushubstelle zurückverfrachtet und hinter der Aushubkette wieder eingebaut.The cleaning of the ballast takes place with the help of track bed cleaning machines. For this purpose, the track grate is raised below the machine and below a chain guide, a chain guide bar, installed, in which the circulating cleaning chain is guided. The chain comprises scraper blades which are hinged together via intermediate links. The clearing blades with the pontics slide in chain guides on exchangeable wear plates. The chain is usually driven hydraulically via a so-called Turas drive. The ballast is excavated from the ballast bed with the aid of the clearing blades, transported upwards into the track bed cleaning machines and falls onto a conveyor belt which pours the contaminated material onto a multi-layer vibrating screen. The fine material is separated from oversize (> 80mm), transported to entrained loading trolleys and stored there until it is disposed of. The cleaned gravel is returned to the excavation site and reinstalled behind the excavation chain.

Jede Schaufel kann mit wechselbaren Kratzerfingern ausgestattet sein, die aus gehärteten Schmiedeteilen bestehen, die mit Hartmetallspitzen versehen sein können. Die einzelnen Kettenglieder unterliegen im Betrieb einem hohen Verschleiß. Insbesondere die zur Erde zeigende Schaufelbodenseite und die das Material fördernde Schaufelarbeitsfläche, die Schaufelbrust und die in der Führung gleitenden Zwischenglieder verschleißen sehr stark. Die Verbindungsbolzen verschleißen ebenfalls und die sie aufnehmenden Bohrungen weiten sich auf. Die Schaufelarbeitsflächen, also die Angriffsfläche der Räumschaufeln, insbesondere die dem Schotter zugewandten äußeren Teile unterliegen ebenfalls einem sehr hohen Verschleiß.Each bucket can be fitted with interchangeable scraper fingers made of hardened forgings that can be fitted with carbide tips. The individual chain links are subject to high wear during operation. In particular, the earth-pointing blade bottom side and the material-promoting blade working surface, the blade root and the intermediate links sliding in the guide wear very heavily. The connecting bolts also wear out and the holes receiving them widen. The blade work surfaces, so the attack surface of the Räumschaufeln, in particular the gravel facing outer parts are also subject to very high wear.

Über ein tolerierbares Maß abgenutzte Flächen werden mit Füllelektroden auftragsgeschweißt, wobei wenigstens die Decklage als Panzerschweißung ausgeführt ist. Da als Schaufelmaterial hochfeste Gusswerkstoffe verwendet werden und diese in hohem Maße wärmeempfindlich sind, ist es erforderlich das zu reparierende Kettenglied während des Schweißvorganges im Wasserbad zu kühlen. Die Auftragsschweißung erfolgt mit entsprechenden Abkühlpausen zwischen den einzelnen aufgeschweißten Lagen. Diese Arbeit ist sehr zeitaufwendig sowie mit sehr hohen Personal- und Materialkosten für die speziellen Schweißelektroden verbunden. Die Reparaturschweißungen können außerdem nur in einer dafür ausgerüsteten Werkstatt und nicht auf der Baustelle ausgeführt werden. Aufgeriebene Bohrungen werden entweder ausgeschweißt und dann mit dem ursprünglichen Durchmesser wieder neu gebohrt oder sie werden aufgebohrt und mit gehärteten Büchsen versehen. Abgenutzte Verbindungsbolzen und Kratzerfinger werden je nach Abnutzungszustand ersetzt. Der obere Bereich der abgenutzten Räumschaufeln wird ebenfalls auftrags- und anschließend panzergeschweißt.Over a tolerable level worn surfaces are job-welded with filling electrodes, at least the top layer is designed as a tank weld. Since high-strength cast materials are used as blade material and these are highly sensitive to heat, it is necessary to cool the chain link to be repaired during the welding process in a water bath. The build-up welding takes place with appropriate cooling pauses between the individual welded-on layers. This work is very time consuming and associated with very high personnel and material costs for the special welding electrodes. In addition, the repair welds can only be performed in a dedicated workshop and not on the construction site. Drilled holes are either welded out and then re-drilled to the original diameter or drilled and hardened. Worn connection bolts and scratch fingers are replaced depending on the wear condition. The upper area of the worn-off reamer blades is also contracted and then armored.

Der Erfindung liegt somit die Aufgabe zugrunde, kostenaufwendige Auftrags-und Panzerschweißungen weitgehend zu vermeiden, wobei eine Reparatur auf der Baustelle schnell und einfach möglich sein soll, um so die Nutzungsdauer der Kette zu verlängern. Die Stillstandszeiten der Gleisbettreinigungsmaschine die mit einem Kettenwechsel einhergehen sollen mit der Erfindung verringert werden.The invention is therefore based on the object to avoid costly order and armored welding largely, with a repair on the site should be quickly and easily possible, so as to extend the useful life of the chain. The downtime of the track bed cleaning machine associated with a chain change to be reduced with the invention.

Die Erfindung löst die gestellte Aufgabe dadurch, dass die besonders dem Verschleiß ausgesetzten Schaufelhauptarbeitsflächen mit auswechselbaren Verschleißblechen ausgestattet sind.The invention solves this problem by the fact that the blade main working surfaces, which are particularly exposed to wear, are equipped with replaceable wear plates.

Dadurch, dass die insbesondere dem Verschleiß an dem auszuräumenden Schotterbett ausgesetzten Schaufelhauptarbeitsflächen mit auswechselbaren Verschleißblechen ausgestattet sind, besteht die Möglichkeit, die Verschleißbleche bei einem ein erlaubtes Maß übersteigendem Verschleiß gegebenenfalls rasch an einer Baustelle zu wechseln. Die Räumketten können bereits ab Werk mit den erfindungsgemäßen Gleitblechen ausgestattet sein bzw. nach erfolgtem Verschleiß und einer durchgeführten Nachbearbeitung durch Abfräsen der verschlissenen Oberfläche mit den erfindungsgemäßen Verschleißblechen ausgestattet werden. Kostenaufwändige Auftrags- und Panzerschweißungen können somit weitgehend vermieden werden und eine Reparatur an einer Baustelle ist jederzeit schnell möglich. Zudem kann durch diese Maßnahme die Nutzungsdauer der Kette erheblich verlängert werden. Besonders dem Verschleiß ausgesetzt ist dabei die Schaufelhauptarbeitsfläche, also jene Fläche, die das abzutragende Gut aufnimmt und aus dem Gleisbett fördert. Besonders dem Verschleiß unterliegt dabei der vordere Schaufelbereich im Bereich der Schaufelspitze. Dies ist der Bereich, der sich insbesondere in das Schotterbett beim Abtragen eingräbt. Meist wird es ausreichend sein rund ein Viertel bis zur Hälfte der Schaufelhauptarbeitsfläche mit einem auswechselbaren Verschleißblech auszustatten.Due to the fact that the blade main working surfaces, which are exposed in particular to the wear on the ballast bed to be cleared, are equipped with exchangeable wear plates, it is possible to rapidly change the wear plates at a construction site if the wear exceeds a permissible extent. The clearing chains can already be factory-fitted with the sliding plates according to the invention or, after wear has been carried out and post-processing carried out by milling away the worn surface, provided with the wear plates according to the invention. Costly order and armored welding can thus be largely avoided and a repair at a construction site is quickly possible at any time. In addition, the service life of the chain can be considerably extended by this measure. Particularly exposed to the wear is the blade main working surface, so that area that receives the material to be removed and promotes from the track bed. In particular, the wear is subject to the front blade area in the region of the blade tip. This is the area that digs into the ballast bed during excavation. It will usually be sufficient to equip around a quarter to half of the bucket main working surface with a replaceable wear plate.

Die Räumkette gleitet zumindest im Gleisbett in einer Führungsschiene, die insbesondere mit Verschleißblechen ausgestattet sein kann. Die Gleitflächen der Kettenglieder an der Kettenführung unterliegen dabei ebenfalls einem massiven Verschleiß aufgrund des abzutragenden mineralischen Gesteins, das mit erheblichem Feinstaubanteil ausgestattet ist. Deshalb sind erfindungsgemäß die dieser Kettenführung zugeordneten und auf dieser gleitenden Gliednebenflächen der Kettenglieder vorzugsweise ebenfalls mit auswechselbaren Verschleißblechen ausgestattet. Diese Gliednebenflächen sind insbesondere jene Flächen, die direkt in der Führung auf entsprechende Gleitschienen gleiten und besagtem Verschleiß unterliegen. Die insbesondere diesem Verschleiß unterliegende Nebenflächen sind die bodenseitigen Gliednebenflächen, die zudem am Untergrund dahingleiten.The clearing chain slides at least in the track bed in a guide rail, which can be equipped in particular with wear plates. The sliding surfaces of the chain links on the chain guide are also subject to massive wear due to the mineral rock to be removed, which is equipped with considerable fine dust content. Therefore, according to the invention, the chain links assigned to this chain guide and sliding on these side surfaces of the chain links are preferably also equipped with replaceable wear plates. These limb surfaces are in particular those surfaces which slide directly in the guide on corresponding slide rails and subject to wear. The secondary surfaces subject to this wear, in particular, are the bottom-side limb surfaces which also slide along the ground.

Besonders stabile Verhältnisse ergeben sich, wenn die den Hauptarbeitsflächen und die den Nebenflächen zugeordneten Verschleißbleche miteinander verbunden, insbesondere verschweißt oder einstückig ausgebildet sind. Damit kann auch im Übergangsbereich zwischen den Verschleißblechen ein Abtrag an der Schaufel vermieden werden.Particularly stable conditions arise when the main working surfaces and the minor surfaces associated wear plates connected to each other, in particular welded or integrally formed. Thus, a removal of the blade can be avoided even in the transition region between the wear plates.

Um einen besonders sicheren und festen Halt der Verschleißbleche an der Schaufel zu gewährleisten, empfiehlt es sich, wenn die Schaufelhauptarbeitsflächen Aufnahmen für die Verschleißbleche aufweisen. Dies können insbesondere Ausfräsungen in der auszustattenden Fläche sein, in welche die Verschleißbleche eingesetzt werden. Besagte Verschleißbleche werden mit den zugeordneten Räumschaufeln vorzugsweise mittels Schrauben verschraubt bzw. mittels Nieten vernietet. Um eine einfache Handhabung der Verschleißbleche zu gewährleisten und um einen übermäßigen Abtrag von Schraubelementen zu vermeiden, die gegebenenfalls im Bereich der Schaufelhauptarbeitsfläche vorgesehen sind, empfiehlt es sich, die Bolzen der Schrauben an den den Schaufelhauptarbeitsflächen abgewandten Rückflächen der Verschleißbleche anzuschweißen, insbesondere damit zu pressverschweißen, womit sichergestellt ist, dass die Schraubenelemente keinem direkten Abrieb unterliegen.In order to ensure a particularly secure and firm hold of the wear plates on the blade, it is recommended that the blade main working surfaces have recordings for the wear plates. This can in particular be cutouts in the surface to be equipped, in which the wear plates are used. Said wear plates are screwed to the associated Räumschaufeln preferably by means of screws or riveted by riveting. In order to ensure easy handling of the wear plates and to avoid excessive removal of screw elements, which are optionally provided in the area of the blade main working surface, it is advisable to weld the bolts of the screws on the blade main working surfaces facing away from the back surfaces of the wear plates, in particular press-welded, thus ensuring that the screw elements are not subject to direct abrasion.

Zusätzlich und alternativ dazu können die Verschleißbleche zur Befestigung insbesondere randseitig wenigstens eine, vorzugsweise langlochartige, Durchbrechung aufweisen, über welche die Verschleißbleche mit den Räumschaufeln verschweißt sind. Die Verschleißbleche werden zur Verbindung mit der Schaufel an die vorgesehene Stelle angesetzt und über die Durchbrechungen mit den Räumschaufeln verschweißt. Zum Ablösen der Verschleißbleche muss lediglich diese Schweißnaht durch einen kurzen Einschnitt mit einer Schleifscheibe od. dgl. gelöst werden. Zusätzlich oder alternativ können die Verschleißbleche stirnseitig mit den Schaufeln verschweißt sein. Darunter versteht sich eine Schweißnaht zwischen Schaufel und Schweißblech im Bereich des Schaufelrandes.In addition and as an alternative to this, the wear plates for attachment can have, in particular, at the edge edge at least one, preferably slot-like, aperture through which the wear plates are welded to the clearing blades. The wear plates are attached to the connection to the blade at the intended location and welded via the openings with the Räumschaufeln. To detach the wear plates only this weld must od by a short incision with a grinding wheel. Like. Be solved. Additionally or alternatively, the wear plates may be welded to the front side with the blades. This is understood to mean a weld seam between the blade and the welding plate in the region of the blade edge.

Ebenso wie die Räumschaufeln empfiehlt es sich, die Verschleißbleche der Zwischenglieder über insbesondere zwei mit Schweißgut aufgefüllte Durchbrechungen mit den Zwischengliedern zu verschweißen. Gegebenenfalls können die Verschleißbleche der Zwischenglieder zusätzlich oder alternativ auch über an der Zwischengliednebenfläche, zwischen den Gliedachsen, vorgesehene Schweißnähte mit den Zwischengliedern verschweißt sein. Als Material für die Verschleißbleche empfehlen sich mit geeignetem Hartmaterial beschichtete Stahlplatten bzw. Stahlplatten aus Hardox 500, 550 oder 600.As well as the clearing blades, it is recommended to weld the wear plates of the intermediate links in particular two perforations filled with weld metal with the intermediate links. Optionally, the wear plates of the intermediate links may additionally or alternatively also be welded to the intermediate links via weld seams provided on the intermediate link side surface, between the link axes. The material used for the wear plates is coated with suitable hard material coated steel plates or steel plates made of Hardox 500, 550 or 600.

Fig. 3 bis 6 zeigen die Räumschaufel 3 in verschiedenen räumlichen Ansichten. Das Verschleißblech 12 ist an der unteren (bodenzugewandten) Gliednebenfläche N der Räumschaufel 3 angebracht. Das Verschleißblech 9 ist an der besonders dem Verschleiß ausgesetzten Schaufelhauptarbeitsfläche H, der Schaufelauflagefläche, angeschraubt und damit leicht wechselbar mit der Räumschaufel 3 verbunden. Die Verbindungsschraube 10 ist mit dem Verschleißblech 9 verschweißt, das an der Hinterseite der Räumschaufel mit den Muttern 11 an der Räumschaufel 3 festgelegt ist. Fig. 3 to 6 show the Räumschaufel 3 in different spatial views. The wear plate 12 is attached to the lower (floor-facing) member side surface N of the bucket 3. The wear plate 9 is screwed to the particularly exposed to wear blade main working surface H, the blade bearing surface, and thus easily changeable connected to the Räumschaufel 3. The connecting screw 10 is welded to the wear plate 9, which is fixed to the rear of the Räumschaufel with the nuts 11 on the Räumschaufel 3.

Fig. 5 und 6 zeigen, dass die Verschleißbleche 12 randseitig je eine langlochartige Durchbrechung 13 aufweisen, über welche die Verschleißbleche 12 mit den Räumschaufeln 3 mittels einer Schweißnaht 13 verschweißt sind. Zusätzlich sind das der Schaufelarbeitshauptfläche H zugeordnete Verschleißblech 9 und das der Gliednebenfläche N zugeordnete Verschleißblech 12 über eine Schweißnaht 14 miteinander verschweißt. FIGS. 5 and 6 show that the wear plates 12 each have a slot-like aperture 13 at the edge over which the wear plates 12 are welded to the Räumschaufeln 3 by means of a weld 13. In addition, the wear plate 9 associated with the blade work main surface H and the wear plate 12 assigned to the link surface N are welded together by a weld seam 14.

Fig. 9 zeigt ein Zwischenglied 5, dessen auf der Führung gleitende Gliednebenfläche N mit einem Verschleißblech 15 ausgestattet ist, das über zwei langlochartige Durchbrechungen 16 mit dem Zwischenglied 5 verschweißt ist. Fig. 9 shows an intermediate member 5, which is slidable on the guide member side surface N is provided with a wear plate 15 which is welded via two slot-like apertures 16 with the intermediate member 5.

Fig. 10 und 11 zeigen Befestigungsvarianten der Verschleißplatte 9 bei der die Schraubenbolzen an der Verschleißplatte 9 angeschweißt sind, einmal konventionell über Kehlnähte 17 (Fig. 10) und einmal als Pressschweißung 18 (Fig. 11). 10 and 11 show fastening variants of the wear plate 9 in which the bolts are welded to the wear plate 9, once conventionally via fillet welds 17 Fig. 10 ) and once as pressure weld 18 ( Fig. 11 ).

Fig. 12 bis 14 zeigen Befestigungsvarianten der Verschleißplatten 9, 12, 15, die vorliegend mittels verschleißplattenstirnseitigen Heftnähten 14, 20, 21 an der Räumschaufel 3 bzw. am Zwischenglied 5 befestigt sind. Kombinationen der vorgenannten Befestigungsvarianten können vorgesehen sein. Fig. 12 to 14 show fastening variants of the wear plates 9, 12, 15, which in the present case by means of wear plate front side stitching seams 14, 20, 21 are attached to the Räumschaufel 3 and the intermediate member 5. Combinations of the aforementioned attachment variants can be provided.

Ausführungsbeispiel Fig. 7 und 8: Die Arbeitsfläche einer, insbesondere abgenutzten, Vorderseite der Räumschaufel 3, die Schaufelhauptarbeitsfläche H, wird plan abgefräst und es werden durch sie die Schaufelbefestigungslöcher gebohrt. An einer Hartmetallplatte 9 z.B. aus Hardox 500 oder an einer beschichteten Stahlplatte werden Schraubenbolzen 10 angeschweißt mit deren Hilfe die Verschleißplatte 9 mit der Räumschaufel 3 unter Zuhilfenahme von Schraubenmuttern 11 verschraubt wird. Nutzt sich die Verschleißplatte 9 im Betrieb ab, kann sie einfach und schnell durch eine neue getauscht werden.embodiment FIGS. 7 and 8 The working surface of a, particularly worn, front of the bucket 3, the bucket main working surface H, is milled flat and the bucket attachment holes are drilled through it. On a hard metal plate 9, for example made of Hardox 500 or on a coated steel plate bolts 10 are welded by means of which the wear plate 9 is screwed to the Räumschaufel 3 with the aid of nuts 11. If the wear plate 9 is used during operation, it can be easily and quickly replaced by a new one.

Die Räumschaufel- und auch die Verbindungsgliedernebenflächen N gleiten in der Kettenführung 7 auf Verschleißblechen 8, wo in Verbindung mit den geförderten Mineralstoffen ein sehr hoher Verschleiß auftritt. Deshalb werden, insbesondere abgenutzte, Räumschaufeln 3 an ihrer (bodenzugewandten) Gliednebenfläche N um ein vorgegebenes Maß plan abgefräst (zwischen 5-20 mm je nach aktuellem Verschleiß) und werden das abgetragene und das verschlissene Material durch ein angeschweißtes Verschleißblech 12 ersetzt. Die Stärke dieses Verschleißbleches 12 wird so gewählt, dass die Abmessungen der Kette dem Neuzustand entsprechen. Damit das Verschleißblech 12 entsprechend hält wird es mit einer länglichen, nahe dem Rand verlaufenden langlochartigen Durchbrechung 13 versehen. Diese nimmt eine Schweißnaht auf über welche das Verschleißblech 12 mit der Räumschaufel 3 verbunden wird, wozu die Durchbrechung 13 mit Schweißgut aufgefüllt wird. Wenn die Durchbrechung 13 aufgefüllt ist kann eine Panzerschweißnaht aufgebracht werden. Zur Fixierung kann die Verschleißplatte 12 zusätzlich oder alternativ mit Schweißnähten 14 geheftet werden. Da die Schweißnaht 14 am Rand des Verschieißbieches angebracht wird, kann das Verschleißblech 12 bei entsprechender Abnutzung einfach gegen ein neues getauscht werden. Dazu werden die Schweißnähte 13, 14 mit einer Flex weggeschliffen, wonach ein neues Verschleißblech angebracht werden kann.The Räumschaufel- and also the Verbindungsgliedernbenflächen N slide in the chain guide 7 on wear plates 8, where in conjunction with the minerals promoted a very high wear occurs. Therefore, in particular worn, bucket blades 3 on their (floor-facing) Gelenknebenfläche N is milled to a predetermined level (between 5-20 mm depending on the current wear) and the worn and worn material is replaced by a welded wear plate 12. The thickness of this wear plate 12 is chosen so that the dimensions of the chain correspond to the new condition. Thus, the wear plate 12 holds accordingly, it is provided with an elongated, near the edge extending slot-like opening 13. This takes on a weld over which the wear plate 12 is connected to the Räumschaufel 3, to which the opening 13 is filled with weld metal. If the opening 13 is filled up, a tank weld can be applied. For fixation, the wear plate 12 may additionally or alternatively be stapled with welds 14. Since the weld 14 is attached to the edge of the Verschiebißbieches, the wear plate 12 can be easily exchanged for a new one with appropriate wear. For this purpose, the welds 13, 14 are ground away with a flex, after which a new wear plate can be attached.

Fig. 6 zeigt die Ausführung der Erfindung für das Zwischenglied 5. Auch hier wird die verschlissene Zwischengliednebenfläche N an der Unterseite plan gefräst und in Weiterer Folge ein formähnliches Verschleißblech 15 angebracht. Über die beiden langlochartigen Durchbrechungen 16 im Verschleißblech wird das Blech wiederum mit dem Zwischenglied 5 verschweißt. Die Durchbrechung wird mit Schweißgut aufgefüllt und an der Oberfläche ggf. gepanzert. Es sind auch erfindungsgemäße Ausführungen denkbar, bei welchen auf die Durchbrechungen verzichtet wird und/oder die Verbindung zwischen Zwischenglied 5 und Verschleißblech 15 über seitliches Anheften der Verschleißplatte an das Zwischenglied erfolgt (siehe Fig. 14). Dies gilt gleichermaßen für die Ausführung beim Schaufelglied (siehe Fig. 12 u. 13). Fig. 6 shows the embodiment of the invention for the intermediate member 5. Again, the worn intermediate member side surface N is milled flat at the bottom and mounted in a subsequent consequence, a shape-like wear plate 15. About the two slot-like apertures 16 in the wear plate sheet is in turn welded to the intermediate member 5. The opening is filled with weld metal and optionally armored on the surface. There are also embodiments of the invention are conceivable in which is dispensed with the openings and / or the connection between the intermediate member 5 and wear plate 15 via lateral attachment of the wear plate to the intermediate member takes place (see Fig. 14 ). This applies equally to the design of the blade member (see Fig. 12 u. 13).

Durch diese Maßnahmen wird die Nutzungsdauer der Schaufel- und Zwischengliedgrundkörper stark erhöht und werden die Instandhaltungskosten deutlich gesenkt.By these measures, the service life of the blade and intermediate member body is greatly increased and the maintenance costs are significantly reduced.
