Description

Die Erfindung bezieht sich gattungsgemäß auf eine Vorrichtung zum Einbringen eines im wesentlichen vertikalen Bodenschlitzes im Zuge der Herstellung einer Dicht- oder Stützwand, - mit Maschinenrahmen, Lagerschild, zumindest zwei Schneidrädern und Motor/Getriebe-Anord­nung, wobei der Lagerschild an den Maschinenrahmen angeschlossen ist und die Schneidräder sowie die Motor/Getriebe-Anordnung trägt, wobei fernerhin die Schneidräder auf einer gemeinsamen Welle angeord­net sind und Teile der Getriebeanordnung von einem Schneidrad um­faßt sind. Es versteht sich, daß der Lagerschild an den Maschinen­rahmen lenkbar angeschlossen sein kann (DE-OS 36 02 387, PatG § 3, (2)).The invention relates generically to a device for introducing an essentially vertical bottom slot in the course of the manufacture of a sealing or support wall, - with machine frame, bearing plate, at least two cutting wheels and motor / gear arrangement, the bearing plate being connected to the machine frame and carries the cutting wheels and the motor / gear arrangement, furthermore the cutting wheels are arranged on a common shaft and parts of the gear arrangement are encompassed by a cutting wheel. It goes without saying that the end shield can be connected to the machine frame in a steerable manner (DE-OS 36 02 387, PatG § 3, (2)).

Bei der bekannten gattungsgemäßen Ausführungsform (DE-OS 34 24 999, PatG § 3 (1)) befinden sich die Antriebsmotoren oberhalb des Lagerschildes im Maschinenrahmen. Transmissionselemente führen von diesen Antriebsmotoren durch Ausnehmungen und Auskammerungen des Lagerschildes bis in den Bereich der Achse der Schneidräder. In Aus­nehmungen oder Auskammerungen des Lagerschildes sind auch andere Getriebe untergebracht. Die Ausnehmungen oder Auskammerungen wer­den mit zunehmendem Antriebsdrehmoment für die Schneidräder größer. Sie reduzieren das Flächenträgheitsmoment des Lagerschildes. Damit nichtsdestoweniger die erheblichen Beanspruchungen aufgenommen wer­den können, muß der Lagerschild entsprechend dick ausgeführt wer­den. Das ist nachteilig, weil daraus ein verhältnismäßig breiter la­gerschildseitiger Abstand der Schneidräder resultiert und folglich bei arbeitenden Schneidrädern zwischen diesen eine störend breite Bodenrippe stehenbleibt.In the known generic embodiment (DE-OS 34 24 999, PatG § 3 (1)), the drive motors are located above the bearing plate in the machine frame. Transmission elements lead from these drive motors through recesses and cavities in the end shield up to the area of the axis of the cutting wheels. Other gears are also accommodated in recesses or cavities in the end shield. The recesses or cavities become larger with increasing drive torque for the cutting wheels. They reduce the moment of inertia of the end shield. So that the considerable stresses can nonetheless be absorbed, the end shield must be made correspondingly thick. This is disadvantageous because it results in a relatively wide distance between the cutting wheels on the end plate side and consequently a disturbingly wide bottom rib remains between the cutting wheels when they are working.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vor­richtung so weiter auszubilden, daß mit einem sehr schmalen Lager­schild mit geringem lagerschildseitigen Abstand der Schneidräder gear­beitet werden kann und nichtsdestoweniger große Antriebsdrehmomente in die Schneidräder eingetragen werden können.The invention has for its object to further develop a generic device so that can work with a very narrow bearing plate with a small bearing plate side distance of the cutting wheels and nonetheless large drive torques can be entered into the cutting wheels.

Zur Lösung dieser Aufgabe lehrt die Erfindung, daß an den Lager­schild ein beidseits vorkragendes, rohrförmiges Gehäuse angeschlos­sen ist, in dem die beiden Schneidräder mit einfassenden Naben, die auf die gemeinsame Welle aufgesetzt sind, gelagert sind, daß auf eine der Naben ein Antriebshohlrad für die Schneidräder aufgesetzt ist, welches in das Gehäuse mit Umlaufspiel eingepaßt ist, und daß das Antriebshohlrad mit den Antriebsritzeln einer Mehrzahl von über den Umfang des Antriebshohlrades verteilten Antriebsmotoren kämmt, die an einem in das Gehäuse eingesetzten Antriebsmotorträger gela­gert sind.To achieve this object, the invention teaches that a double-sided projecting tubular housing is connected to the bearing plate, in which the two cutting wheels with surrounding hubs, which are placed on the common shaft, are mounted, that on one of the hubs a drive ring gear for the Cutting wheels is placed, which is fitted into the housing with clearance, and that the drive ring gear meshes with the drive pinions of a plurality of drive motors distributed over the circumference of the drive ring gear, which are mounted on a drive motor carrier inserted into the housing.

Das läßt sich im einzelnen auf verschiedene Weise verwirklichen. Eine bevorzugte Ausführungsform der Erfindung, die sich durch Ein­fachheit und Funktionssicherheit auszeichnet, ist dadurch gekennzeich­net, daß die Schneidräder mit ihren Naben in dem Gehäuse mittels Kegelrollenlager gelagert sind. Das Antriebshohlrad ist zweckmäßiger­weise auf die zugeordnete Nabe mittels Spannsatz aufgesetzt. Die An­zahl der über den Umfang des Antriebshohlrades verteilten Antriebs­motoren ist grundsätzlich beliebig. Zur Erzielung sehr gleichmäßiger Beanspruchungsverhältnisse wird man im allgemeinen zumindest drei Antriebsmotoren vorsehen. Eine bevorzugte Ausführungsform der Erfin­ dung, die es erlaubt, sehr große Antriebsdrehmomente in die Schneid­räder einzuleiten, ist dadurch gekennzeichnet, daß über den Umfang des Antriebshohlrades fünf Antriebsmotoren angeordnet sind, die als Hydraulikmotoren ausgeführt sind. Die Schneidräder wird man auf die gemeinsame Welle im allgemeinen unter Zwischenschaltung einer Verzahnung aufsetzen, die Schneidräder können dann bei Wartungs- und Pflegearbeiten auch leicht abgezogen werden.This can be achieved in various ways. A preferred embodiment of the invention, which is characterized by simplicity and functional reliability, is characterized in that the cutting wheels are mounted with their hubs in the housing by means of tapered roller bearings. The drive ring gear is expediently placed on the assigned hub by means of a clamping set. In principle, the number of drive motors distributed over the circumference of the drive ring gear is arbitrary. In order to achieve very uniform stress conditions, at least three drive motors will generally be provided. A preferred embodiment of the Erfin Dung, which allows very large drive torques to be introduced into the cutting wheels, is characterized in that five drive motors are arranged over the circumference of the drive ring gear, which are designed as hydraulic motors. The cutting wheels will generally be placed on the common shaft with the interposition of a toothing, the cutting wheels can then also be easily removed during maintenance and care work.

Die erreichten Vorteile sind darin zu sehen, daß bei der erfindungsge­mäßen Vorrichtung mit einem sehr schmalen Lagerschild und folglich mit einem geringen lagerschildseitigen Abstand der Schneidräder gear­beitet werden kann. Zwischen den Schneidrädern bleibt daher nur eine schmale Bodenrippe stehen, die wegbricht oder leicht freige­spült werden kann. Das für die Erfindung wesentliche Gehäuse be­wirkt zugleich eine sichere Kapselung der Motor/Getriebe-Anordnung. Es versteht sich, daß zwischen den rotierenden und den nichtrotieren­den Teilen geeignete Dichtungen angeordnet werden. Spalträume zwi­schen rotierenden und nichtrotierenden Teilen können ohne Schwierig­keiten gespült und dadurch freigehalten werden.The advantages achieved can be seen in the fact that the device according to the invention can be used with a very narrow bearing plate and consequently with a small distance between the cutting wheels on the bearing plate side. Therefore, only a narrow bottom rib remains between the cutting wheels, which breaks away or can be easily washed away. The housing essential for the invention also ensures a safe encapsulation of the motor / gear arrangement. It goes without saying that suitable seals are arranged between the rotating and the non-rotating parts. Gaps between rotating and non-rotating parts can be easily flushed and thus kept free.
