Description

Die Erfindung betrifft eine Schienenschleifvorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a rail grinding device according to the preamble of claim 1.

Bei derartigen Vorrichtungen, wie sie aus der Praxis bekannt sind, ist die Schleifeinheit zentral unterhalb des Fahrzeugs montiert, während sich die schienengängigen Räder vor der Vorderachse und hinter der Hinterachse befinden. Im Einsatzfall wird das Fahrzeug über die Schienen gefahren, woraufhin man die schienengängigen Räder absenkt und dadurch das Fahrzeug geringfügig anhebt. Auch in angehobenem Zustand bleiben die straßengängigen Räder mit dem Boden in Berührung. Sie verlieren dadurch ihre Lenkungsfunktion, nicht jedoch ihre Funktion als Reibradantrieb.In such devices, as known from practice the grinding unit is centrally below the Vehicle mounted while the rail wheels located in front of the front axle and behind the rear axle. in the The vehicle is driven over the rails, whereupon you lower the rail-accessible wheels and thereby slightly raises the vehicle. Even when raised the road wheels stay in contact with the ground. As a result, they lose their steering function, but not their function as a friction wheel drive.

So beschreibt die CH-A-688 626 eine Schienenschleifvorrichtung mit einem motorisierten Fahrzeug, das sowohl straßengängige als auch schienengängige Räder aufweist. Dem Fahrzeug ist eine Schleifeinheit zugeordnet, die einen weiteren Satz schienengängiger Räder aufweist. Durch ein Absenken der am hinteren Ende des Fahrzeugs und zwischen den straßengängigen Rädern angeördneten schienengängigen Räder kann das Fahrzeug selber angeboben werden.For example, CH-A-688 626 describes a rail grinding device with a motorized vehicle that is both roadworthy as well as rail-capable wheels. the A grinding unit is assigned to the vehicle and another Has set of rail-accessible wheels. By lowering the one at the rear of the vehicle and between the roadworthy wheels arranged railable wheels the vehicle can be lifted by yourself.

Es hat sich gezeigt, daß die Einsatzmöglichkeiten dieser Vorrichtung begrenzt sind.It has been shown that the possible uses of this Device are limited.

Zum einen ist der Abstand zwischen den vorderen und den hinteren schienengängigen Rädern relativ groß. Dadurch erschwert sich das Eingleisen dieser Räder. Vor allen Dingen aber begrenzt der Abstand denjenigen Kurvenradius, der von der Schleifeinheit noch problemlos bearbeitet werden kann.Firstly, the distance between the front and the rear rail wheels relatively large. This makes it difficult the iron of these wheels. Above all but the distance limits the curve radius that from the milling unit can still be processed easily.

Ferner bedingt die Konstruktion, daß die straßengängigen Räder über gesonderte Hydraulikmotoren einzeln angetrieben werden. Das Fahrzeug ist also für längere Straßenfahrten nicht geeignet.Furthermore, the construction requires that the street Wheels individually driven by separate hydraulic motors become. So the vehicle is for longer road trips not suitable.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Schienenschleifvorrichtung dahingehend zu verbessern, dass engere Kurvenradien bewältigt, das Eingleisen erleichtert und zudem noch längere Straßenfahrten durchführbar sind.The invention has for its object a generic To improve the rail grinding device that negotiates tighter curve radii, which makes the single track easier and also longer road trips are.

Zur Lösung dieser Aufgabe zeichnet sich die Schienenschleifvorrichtung der eingangs genannten Art erfindungsgemäß durch kennzeichnenden Merkmale des Anspruchs 1 aus.To solve this task, the rail grinding device stands out of the type mentioned in the invention by characterizing features of claim 1.

Der Hydraulikantrieb wirkt direkt auf die schienengängigen Räder ein. Die straßengängigen Räder können in konventioneller Weise über den Verbrennungsmotor des Fahrzeugs angetrieben werden. Für die Kardanwelle steht ausreichend Platz zur Verfügung. Es werden also Straßenfahrten beliebiger Länge möglich.The hydraulic drive acts directly on the rail-accessible ones Wheels. The road wheels can be conventional Way driven by the internal combustion engine of the vehicle become. There is enough space for the cardan shaft to disposal. So road trips are becoming more arbitrary Length possible.

Während der Straßenfahrt ist die Schleifeinheit auf dem Fahrzeug aufgesattelt. Im Einsatzfall wird sie auf die Schienen abgesenkt und vom Fahrzeug geschleppt. Der Längsabstand der schienengängigen Räder der Schleifeinheit läßt das Bearbeiten von extrem kleinen Kurvenradien zu.The grinding unit is on the road while driving Vehicle saddled up. In the event of an emergency, it is placed on the Rails lowered and towed by the vehicle. The longitudinal distance the track-accessible wheels of the grinding unit do that Machining of extremely small curve radii too.

Die Schleifeinheit bildet eine vom Fahrzeug gesonderte Baugruppe, so daß der zentrale Raum unterhalb des Fahrzeugs frei wird. Die schienengängigen Räder des Fahrzeugs sind erfindungsgemäß in dessen Längsrichtung zwischen den straßengängigen Rädern angeordnen. Der Längsabstand der schienengängigen Räder des Fahrzeugs kann also minimiert werden, so daß beliebig enge Kurvenradien durchfahren werden können. Außerdem vereinfacht sich das Eingleisen.The grinding unit forms a separate one from the vehicle Assembly so that the central space below the vehicle becomes free. The rail-accessible wheels of the vehicle are in accordance with the invention in the longitudinal direction between the road-going Arranged wheels. The longitudinal distance of the rail-accessible Wheels of the vehicle can thus be minimized that any tight curve radii can be traversed. The single rail is also simplified.

Vorzugsweise sind die schienengängigen Räder des Fahrzeugs in ein vorderes und ein rückwärtiges Paar unterteilt, wobei jedes Paar an einer gesondert hydraulisch betätigbaren Schwinge sitzt. Beim Eingleisen wird zuerst das rückwärtige Radpaar über die Schienen manöveriert und in die Schienen abgesenkt. Sodann erfolgt das Ausrichten des vorderen Radpaares, wobei das Fahrzeug rückwärts manöveriert wird. Sind beide Radpaare in die Schienen eingesenkt, erfolgt das gemeinsame Anheben des Fahrzeugs, wobei die straßengängigen Räder, da nun funktionslos, den Kontakt mit dem Boden verlieren. Bei einer Hubhöhe von mehr als 100 mm können sie also auch keine durch die Straße bedingten Stöße auf das System übertragen, wie es bei einem Reibradantrieb der Fall ist. Das Eingleisen der Schleifeinheit wurde vorher durchgeführt, also bei voller Manöverierfähigkeit des Fahrzeugs.Preferably, the rail-accessible wheels of the vehicle divided into a front and a rear pair, each pair on a separately hydraulically operated Swing arm sits. With the single rail, the rear is first Pair of wheels maneuvered over the rails and into the rails lowered. Then the front wheel pair is aligned, the vehicle being maneuvered backwards. are both pairs of wheels sunk into the rails, the joint takes place Lifting the vehicle, being the roadworthy Wheels, as they are now inoperative, lose contact with the ground. With a lifting height of more than 100 mm you can also no impacts on the road System transfer, as is the case with a friction wheel drive is. The grinding unit was ironed in beforehand, in other words with full vehicle maneuverability.

In Weiterbildung der Erfindung wird vorgeschlagen, daß die Hub- und Transporteinrichtung hydraulisch betätigbar ist und folgende Merkmale aufweist:

  • einen in Längsrichtung des Fahrzeugs horizontal verschiebbaren ersten Mast,
  • einen am ersten Mast geführten, vertikal verschiebbaren zweiten Mast und
  • einen am zweiten Mast angeordneten Gabelträger mit Gabelarmen zum Eingriff in die Schleifeinheit.
In a further development of the invention, it is proposed that the lifting and transport device can be operated hydraulically and has the following features:
  • a first mast horizontally displaceable in the longitudinal direction of the vehicle,
  • a vertically displaceable second mast guided on the first mast and
  • a fork carriage arranged on the second mast with fork arms for engaging in the grinding unit.

Die Hub- und Transporteinrichtung weist also wesentliche Merkmale gebräuchlicher Gabelstapler auf, allerdings mit der Maßgabe, daß der Gabelträger aus seiner Ruheposition heraus nicht angehoben, sondern abgesenkt wird. Auch ist der erste Mast nicht starr mit dem Fahrzeug verbunden. Vielmehr läßt er sich in dessen Längsrichtung verschieben. In aufgesattelter Position befindet sich die Schleifeinheit auf dem rückwärtigen Bereich des Fahrzeugs. Der Vorgang des Eingleisens wird dadurch eingeleitet, daß der erste Mast auf dem Fahrzeug nach hinten fährt und die Schleifeinheit hinter das rückwärtige Ende des Fahrzeugs transportiert. Sodann wird der zweite Mast mit dem Gabelträger und der an dessen Gabelarmen hängenden Schleifeinheit abgesenkt.The lifting and transport device therefore has essential features Features of common forklifts, but with the Provided that the fork carriage from its rest position not raised, but lowered. Is also the first Mast not rigidly connected to the vehicle. Rather leaves it moves in its longitudinal direction. In semi-mounted The grinding unit is on the rear position Area of the vehicle. The process of ironing is initiated by the first mast on the vehicle moves backwards and the grinding unit behind that transported rear end of the vehicle. Then will the second mast with the fork carriage and the one on its fork arms hanging grinding unit lowered.

Um das Eingleisen, insbesondere in Kurvenabschnitten, zu erleichtern, ist der Gabelträger relativ zum zweiten Mast in Querrichtung des Fahrzeugs horizontal verschiebbar. Alternativ oder zusätzlich dazu besteht die Möglichkeit, daß die Schleifeinheit eine um eine vertikale Achse drehbare Kupplung für den Eingriff der Gabelarme aufweist.To the single track, especially in curve sections facilitate, the fork carriage is in relative to the second mast Transverse direction of the vehicle can be moved horizontally. alternative or in addition, there is a possibility that the Grinding unit a coupling rotatable about a vertical axis for engaging the fork arms.

In wesentlicher Weiterbildung der Erfindung wird vorgeschlagen, daß die Schleifeinheit über eine kardanische Zugstange mit dem Gabelträger verbunden ist. Diese Verbindung bleibt ständig erhalten, wodurch sich die Handhabbarkeit der Vorrichtung stark vereinfacht. Sofort nach dem Absenken und Eingleisen ist die Schleifeinheit einsatzbereit. In aufgesatteltem Zustand übernimmt die kardanische Zugstange Arettierfunktionen.In an essential further development of the invention it is proposed that the grinding unit has a cardanic pull rod is connected to the fork carriage. This connection remains constantly intact, which improves the manageability of the Device greatly simplified. Immediately after lowering and The milling unit is ready for use on its own. Saddled up The gimbal pull rod assumes the state of function.

Vorteilhafterweise bietet die Kupplung der Schleifeinheit den Gabelarmen des Gabelträgers ein vertikales Spiel. Dadurch wird es möglich, den Gabelträger nach dem Eingleisen der Schleifeinheit noch weiter abzusenken, so daß die Gabelarme den Kontakt mit der Kupplung der Schleifeinheit verlieren. Die Schleifeinheit wird also schwingungsmäßig von der Hub- und Transporteinrichtung abgekoppelt.The coupling of the grinding unit advantageously offers vertical play on the fork arms of the fork carriage. This makes it possible to move the fork carriage after the single iron lower the grinding unit even further so that the fork arms lose contact with the coupling of the milling unit. The grinding unit is vibrated by the Lifting and transport device decoupled.

Vorzugsweise ist ein Endanschlag zum Begrenzen der Rückwärtsbewegung des ersten Mastes vorgesehen. Auch dies trägt dazu bei, die Handhabung der Vorrichtung zu vereinfachen.Preferably there is an end stop to limit the backward movement of the first mast. This also bears help to simplify the handling of the device.

Bei dem Endanschlag kann es sich um einen elektronischen Sensor handeln. Der Endanschlag kann jedoch auch mechanischer Natur sein. Er dient dann gleichzeitig dazu, die Zugkräfte beim Schleppen der Schleifeinheit direkt in das Fahrzeug einzuleiten. Die Hydraulik der Hub- und Transporteinrichtung wird entsprechend entlastet. Dem selben Zweck dient ein weiteres vorteilhaftes Merkmal, nämlich die Verwendung mindestens einer Riegelstange, die mit dem Gabelträger verbunden ist und bei einer Abwärtsbewegung des zweiten Mastes in eine Riegelöffnung des Fahrzeugs eingreift.The end stop can be an electronic one Act sensor. However, the end stop can also be mechanical Be nature. It then also serves the tensile forces when dragging the milling unit directly into the vehicle initiate. The hydraulics of the lifting and transport device is relieved accordingly. Serves the same purpose another advantageous feature, namely the use at least one locking bar connected to the fork carriage and with a downward movement of the second mast engages in a bolt opening of the vehicle.

Ferner werden Vorkehrungen getroffen, um die aufgesattelte Schleifeinheit sicher transportieren zu können. Hierzu dient eine am rückwärtigen Ende des Fahrzeugs angeordnete, hydraulisch schwenkbare und verriegelbare Klappe, die die aufgesattelte Schleifeinheit arretiert. Ferner besteht die vorteilhafte Möglichkeit, Mulden in das Fahrzeug und ggf. in die Klappe einzulassen, die zur arretierenden Aufnahme der Räder der aufgesattelten Schleifeinheit dienen. Dabei können neben den Mulden seitliche Wangen angeordnet sein,.die in Querrichtung des Fahrzeugs an den Rädern der aufgesattelten Schleifeinheit angreifen.Precautions are also taken to the saddled up To be able to transport the milling unit safely. For this is used at the rear end of the vehicle, hydraulically swiveling and lockable flap, which the mounted grinding unit locked. Furthermore, there is advantageous possibility of troughs in the vehicle and possibly in to let in the flap, which is used to hold the Serve wheels of the saddled grinding unit. You can side cheeks must be arranged next to the troughs Transverse direction of the vehicle on the wheels of the fifth wheel Attack the milling unit.

Da die Schleifeinheit sowohl während des Transportes als auch im Einsatz über die kardanische Zugstange ständig mit dem Gabelträger und damit mit dem Fahrzeug gekoppelt ist, bietet es sich an, die Schleifeinheit über Ver- und Entsorgungsleitungen ständig mit dem Fahrzeug zu verbinden. Dabei handelt es sich beispielsweise um eine Saugleitung zum Absaugen des Schleifstaubs, wobei diese Saugleitung mit einem auf dem Fahrzeug angeordneten Filter verbunden ist. Vorzugsweise dient die gelieferte Luft zur Kühlung Hydraulik- und Elektroaggregate des Fahrzeugs.Since the grinding unit is used both during transport and also in use with the cardanic drawbar the fork carriage and thus coupled to the vehicle, it makes sense to use the grinding unit via supply and disposal lines to constantly connect to the vehicle. there it is for example a suction line for suction of grinding dust, this suction line with a filter arranged on the vehicle is connected. Preferably the air supplied is used for cooling hydraulic and Electrical units of the vehicle.

Auch kommen elektrische und hydraulische Leitungen in Frage, und zwar insbesondere dann, wenn die Schleifeinheit elektrisch verstellbare Schleiftopf-Wellen aufweist, die von mindestens einem Hydraulikmotor unter Zwischenschaltung mindestens eines Riementriebes antreibbar sind.Electrical and hydraulic lines also come in Question, especially if the milling unit has electrically adjustable cup wheels which by at least one hydraulic motor with at least an intermediate connection a belt drive can be driven.

Die Schleifeinheit bietet die Möglichkeit, extrem kleine Spurweiten (1000 mm und weniger) beidseitig gleichzeitig zu bearbeiten, wobei ein Verschwenken der Schleiftöpfe um 45° möglich ist. Hydraulische Motoren bauen kleiner als elektrische Motoren und laufen mit einer Drehzahl von bis zu 3500 U/min, wobei die Keil- oder Zahnriementriebe die Schleiftöpfe mit 7000 bis 8000 U/min antreiben. Die Riementriebe bieten gleichzeitig eine schwingungs- und kraftmäßige Abkopplung der Schleiftöpfe, so daß der Hydraulikmotor geschont wird.The milling unit offers the possibility of extremely small Gauges (1000 mm and less) closed on both sides at the same time edit, swiveling the cup wheels by 45 ° is possible. Hydraulic motors are smaller than electric ones Motors and run at a speed of up to 3500 rpm, the V-belt or toothed belt drives the Drive grinding cups at 7000 to 8000 rpm. The belt drives offer a vibration and strength at the same time Uncoupling the cup wheels so that the hydraulic motor is protected becomes.

Das Eingleisen sowohl der Schleifeinheit als auch des Fahrzeugs kann extern gesteuert werden, ggf. unter Einsatz einer Video-Überwachung. Auch der eigentliche Schleifvorgang ist extern steuerbar. The single iron of both the milling unit and the The vehicle can be controlled externally, if necessary using it video surveillance. Even the actual grinding process can be controlled externally.

Fig. 1 läßt erkennen, daß die Gabelarme 11 während des Betriebes geringfügig abgesenkt sind, so daß sie mit der Schleifeinheit 2 nicht mehr in Berührung stehen. Eine Übertragung von Stößen ist also ausgeschlossen.Fig. 1 shows that the fork arms 11 during the Operation are slightly lowered so that they with the No longer touch milling unit 2. A transfer bumps are excluded.

Beim Aufsatteln der Schleifeinheit 2 wird diese, wie erwähnt, erst in die strichpunktiert in Fig. 1 gezeigte Position angehoben. Sodann fährt der äußere Mast 8 des Gabelstaplers auf dem Fahrzeug 1 nach vorne und nimmt dabei die Schleifeinheit 2 mit. Letztere gelangt also in die in Fig. 2 gezeigte Position.When the grinding unit 2 is saddled, it is, as mentioned, only in the dot-dash position shown in Fig. 1 raised. Then the outer mast 8 of the forklift moves on the vehicle 1 forward and takes the Grinding unit 2 with. The latter thus reaches the one in FIG. 2 shown position.

Da die Schleifeinheit 2 in der Transportposition nach hinten über das Fahrzeug 1 hinausragt, wird eine am rückwärtigen Ende des Fahrzeugs angelenkte Klappe 15 hochgeschwenkt und arretiert. Sie stützt die rückwärtigen Räder 6 der Schleifeinheit 2.Since the grinding unit 2 is in the transport position If it protrudes beyond the vehicle 1 at the rear, one becomes at the rear Flap 15 hinged at the end of the vehicle and locked. It supports the rear wheels 6 of the Milling unit 2.

Wie in Fig. 3 dargestellt, sind Mulden 16 in die Klappe 15 eingearbeitet, um den Rädern 6 zusätzlichen Halt zu verleihen. Entsprechende Mulden 16 sind, wie in Fig. 1 angedeutet, auch auf dem Fahrzeug 1 vorgesehen. Neben den letztge-, nannten Mulden befinden sich seitliche Wangen 17, die die Schleifeinheit 2 in Querrichtung sichern. Im übrigen wird die Schleifeinheit 2, wie bereits erwähnt, von der Zugstange 14 arretiert.As shown in Fig. 3, troughs 16 are in the flap 15 incorporated to give the wheels 6 additional grip. Corresponding troughs 16 are, as indicated in FIG. 1, also provided on the vehicle 1. In addition to the last called troughs are side cheeks 17, the Secure the milling unit 2 in the transverse direction. Otherwise the grinding unit 2, as already mentioned, from the pull rod 14 locked.

Während des Schleppens soll dafür gesorgt werden, daß die Zugkräfte nicht in die den Gabelstapler betätigende Hydraulik eingeleitet werden. Hierzu sind am Gabelträger 10 Riegelstangen 18 vorgesehen, die in entsprechende Riegelöffnungen 19 des Fahrzeugs 1 eingreifen.During towing it should be ensured that the tensile forces are not in the hydraulic system actuating the forklift be initiated. For this purpose, the fork carriage 10 Locking rods 18 are provided, which in corresponding locking openings 19 of the vehicle 1 intervene.

Die Schleifeinheit 2 ist mit Schleiftöpfen 20 versehen, deren Wellen elektrisch verstellt und verschwenkt werden können. Der Antrieb der Wellen erfolgt über Hydraulikmotoren 21, und zwar unter Zwischenschaltung von Riementrieben 22, die die Schleiftöpfe 20 schwingungs- und kraftmäßig von den Hydraulikmotoren 21 abkoppeln.The grinding unit 2 is provided with grinding cups 20, whose shafts are electrically adjusted and swiveled can. The shafts are driven by hydraulic motors 21, with the interposition of belt drives 22, the vibration cups 20 from the vibration and force Uncouple hydraulic motors 21.

Da die Schleifeinheit 2, wie erwähnt, permanent mit dem Fahrzeug 1 verbunden ist, bleibt auch die Verbindung entsprechender Ver- und Entsorgungsleitungen 23 ständig bestehen. So ist die Schleifeinheit 2 an eine Absaugeinrichtung 24, einen Stromerzeuger 25 und eine Hydraulikeinrichtung 26 angeschlossen. Diese Aggregate werden von einer lediglich angedeuteten Haube abgedeckt, wobei die in der Absaugeinrichtung 24 gereinigte Luft zur Kühlung der Aggregate dient.Since the grinding unit 2, as mentioned, permanently with the Vehicle 1 is connected, the connection remains corresponding Supply and disposal lines 23 consist constantly. So is the grinding unit 2 to a suction device 24, a power generator 25 and a hydraulic device 26 connected.
