Description

Die Erfindung betrifft eine Baumaschine zum Bearbeiten von Bodenoberflächen nach dem Oberbegriff des Anspruchs 1.The invention relates to a construction machine for processing floor surfaces the preamble of claim 1.

Derartige Baumaschinen, zum Beispiel Großfräsen, Kaltfräsen, Surface Miner oder Recycler, weisen einen Maschinenrahmen auf, in dem eine quer zu der zu bearbeitenden Fahrspur verlaufende Fräswalze drehbar gelagert ist. Der Maschinenrahmen nimmt ferner noch den Fräswalzenantrieb auf und wird von mehreren vorzugsweise vor und hinter der Fräswalze angeordneten Fahrschiffen eines Fahrwerks höhenverstellbar getragen.Such construction machines, for example large milling machines, cold milling machines, surface miners or Recyclers have a machine frame, in which one is transverse to the one to be processed Lane milling drum is rotatably mounted. The machine frame also takes on the milling drum drive and is preferred by several In front of and behind the milling drum, there is a height-adjustable landing gear carried.

Derartige Groß- oder Kaltfräsen, bzw. Recycler werden z.B. zum Abfräsen von Straßenbelägen, auf Autobahnen oder Landstraßen eingesetzt. Die Fräswalzen sind auf ihrer Mantelfläche mit auswechselbaren Werkzeugen bestückt. Bei äußerst harten Straßenbelägen kann es vorkommen, dass die Werkzeuge lediglich eine Standzeit von einer halben Stunde aufweisen und dass dann alle Werkzeuge der Fräswalze ausgetauscht werden müssen. Hierzu kann das Fahrwerk oder die Fräswalze angehoben werden bis die Fräswalze nicht mehr mit der Bodenoberfläche in Kontakt ist. Eine Bedienungsperson, z.B. ein Maschinist, kann nach Wegklappen eines Gehäuseteils des Walzengehäuses in einem Arbeitsraum an der Fräswalze den Austausch der Werkzeuge vornehmen. Bei derartigen Baumaschinen mit mechanischem Antrieb muss die Fräswalze zum Auswechseln aller Werkzeuge von Zeit zu Zeit gedreht werden. Dies kann von Hand geschehen, was allerdings sehr hohe Kräfte erfordert. Es ist auch bekannt, die Arbeits- oder Fräswalze mit Hilfe einer Handkurbel zu drehen, wobei die Handkurbel mit einem Untersetzungsgetriebe der Fräswalze gekoppelt wird. Da die Handkurbel nur außen an der Maschine ansetzbar ist, sind für den Werkzeugwechselvorgang zwei Bedienungspersonen erforderlich, oder die Bedienungsperson muss zum Weiterdrehen der Fräswalze aus dem Arbeitsraum herauskommen, was letztlich zeitraubend ist.Such large or cold milling machines or recyclers are e.g. for milling off road surfaces, used on motorways or country roads. The milling drums are open equipped with interchangeable tools. With extremely hard Road surfaces can happen that the tools only have a service life of half an hour and then all the tools of the milling drum need to be replaced. For this purpose, the undercarriage or the milling drum can be raised until the milling drum is no longer in contact with the floor surface. An operator, e.g. a machinist, after folding away a housing part exchange of the roller housing in a working area on the milling drum of the tools. In such construction machines with mechanical drive the milling drum must be rotated from time to time to replace all tools become. This can be done by hand, but this requires very high forces. It is also known to use the work or milling drum with a hand crank to rotate, the hand crank with a reduction gear of the milling drum is coupled. Since the hand crank can only be attached to the outside of the machine two operators are required for the tool changing process, or the The operator must continue to turn the milling drum out of the work area come out, which is ultimately time consuming.

Der Arbeitsraum an der Fräswalze für den Werkzeugwechselvorgang ist beengt, wobei der Maschinist in kniender oder hockender Stellung den Werkzeugwechsel vornehmen muss. Dabei kann der Untergrund uneben, lose und/oder nass sein, was die Arbeitsbedingungen und die gesundheitliche Belastung des Maschinisten zusätzlich belasten kann.The working space on the milling drum for the tool changing process is cramped, the machine operator kneeling or crouching to change tools must make. The surface can be uneven, loose and / or wet, which the working conditions and the health of the machine operator can strain.

Alternativ können die Gelenkarme auch mit dem Maschinenrahmen gekoppelt sein. Nach einer weiteren Alternative kann die gelenkige Ankopplung auch mit einem einzigen teleskopierbaren Gelenkarm erfolgen. Alternatively, the articulated arms can also be coupled to the machine frame. According to a further alternative, the articulated coupling can also be carried out with a single one telescopic articulated arm.

Der Sitz kann eine Fernbedienung für einen Hilfsantrieb der Arbeitswalze aufweisen, wobei der Hilfsantrieb mit dem Antriebsstrang koppelbar ist. Die Bedienungsperson kann mit Hilfe der Fernbedienung einen Hilfsantrieb ansteuern, der die Arbeitswalze im angehobenen Zustand um einen vorbestimmten oder wählbaren Drehwinkel verdreht.The seat can have a remote control for an auxiliary drive of the work roll, wherein the auxiliary drive can be coupled to the drive train. The operator can use the remote control to control an auxiliary drive that drives the work roll rotated by a predetermined or selectable angle of rotation in the raised state.

Der Hilfsantrieb dreht die Arbeitswalze bei jeder Betätigung um einen kleinen Drehwinkel, um noch nicht ausgewechselte Werkzeuge (Fräsmeißel) in eine günstigere Montageposition zu bringen. Dabei ist das Drehmoment des Hilfsantriebs etwas höher als das Trägheitsmoment der Arbeitswalze und des mitbewegten Antriebsstrangs, um einerseits eine Drehbewegung zu ermöglichen und anderseits die Unfallgefahr möglichst gering zu halten. Der Antriebsmotor für die Arbeitswalze ist dabei außer Betrieb oder entkoppelt.The auxiliary drive rotates the work roll by a small angle of rotation with each actuation, for tools that have not yet been replaced (milling chisels) in a cheaper one Bring assembly position. The torque of the auxiliary drive is slightly higher as the moment of inertia of the work roll and the driven drive train, to enable a rotary movement on the one hand and the risk of an accident on the other to keep as low as possible. The drive motor for the work roll is included out of order or decoupled.

Infolge der definierten Sitzstellung der Bedienungsperson auf dem Sitz ist zusätzlich die Unfallgefahr beim Drehen der Arbeitswalze reduziert, da die Bedienungsperson im Gegensatz zu einer knienden oder hockenden Zwangslage auf dem Sitz, insbesondere bei rutschigem, weichen Untergrund nicht ausrutschen und von der bewegten Arbeitswalze erfasst werden kann.Due to the defined seating position of the operator on the seat is additional the risk of accidents when rotating the work roll is reduced since the operator in contrast to a kneeling or squatting position on the seat, in particular on slippery, soft ground, do not slip and move Work roll can be detected.

Der Zeitbedarf für den Werkzeugwechsel wird reduziert, da der Hilfsantrieb von der Bedienungsperson an der Arbeitswalze betätigt werden kann. Da der Hilfsantrieb die Arbeitswalze mit einer geringen Leistung antreibt, ist die Unfallgefahr nahezu ausgeschlossen, die dadurch entsteht, dass sich Bekleidungsteile der Bedienungsperson in den Werkzeugen der Arbeitswalze verfangen können, wenn diese gedreht wird. Da das Drehmoment des Hilfsantriebs gerade genügt, um eine Drehbewegung der Arbeitswalze mit ca. 3 U/min zu ermöglichen, kann der Motor des Hilfsantriebs beim Auftreten höherer Kräfte an der Arbeitswalze schnell gestoppt werden. Außerdem stoppt der Hilfsantrieb nach jeder Inbetriebnahme automatisch nach ca. 4 Sekunden.The time required for the tool change is reduced because the auxiliary drive from the Operator can be operated on the work roll. Since the auxiliary drive Drives work roller with a low power, the risk of accidents is almost eliminated, which arises from the fact that clothing parts of the operator can get caught in the tools of the work roll when it is rotated. Since the torque of the auxiliary drive is just sufficient to rotate the The motor of the auxiliary drive can enable work rolls with approx. 3 rpm Occurrence of higher forces on the work roll can be stopped quickly. Moreover The auxiliary drive stops automatically after approx. 4 seconds after each start-up.

An den Gelenkarmen und/oder an dem Sitz kann eine Schale zur Aufnahme von Fräsmeißeln und den für den Werkzeugwechsel benötigten Werkzeugen befestigt sein. On the articulated arms and / or on the seat, a shell for receiving Milling chisels and the tools required for changing tools his.

Der Sitz kann um eine horizontale Achse verschwenkbar sein. Die Verschwenkbarkeit des Sitzes um eine horizontale Achse ermöglicht es, die Sitzfläche zu verschwenken, damit die Gelenkarme in der Ruhestellung im Fahrbetrieb parallel an der Seitenwand zusammengeklappt werden können und der Sitz seitlich neben dem Fahrschiff platzsparend aufbewahrt werden kann. Der Sitz kann auch als Klappsitz gestaltet sein, um den Platzbedarf weiter zu reduzieren.The seat can be pivoted about a horizontal axis. The pivotability of the seat around a horizontal axis makes it possible to pivot the seat, thus the articulated arms in parallel in the rest position when driving the side wall can be folded and the seat on the side next to the Vessel can be stored to save space. The seat can also be used as a folding seat be designed to further reduce the space requirement.

Alternativ kann vorgesehen sein, dass die Sitzschale des Sitzes abnehmbar ist.Alternatively, it can be provided that the seat shell of the seat can be removed.

Mindestens einer der Gelenkarme kann teleskopierbar sein. Damit kann die Reichweite des Sitzes vergrößert werden.At least one of the articulated arms can be telescopic. So that the range the seat can be enlarged.

Der Sitz kann höhenverstellbar sein. Auf diese Weise kann der Sitz an die Größe einer Bedienungsperson oder auch an die Lage der Werkzeuge auf dem Umfang der Arbeitswalze angepasst werden.The seat can be adjustable in height. This way the seat can be sized an operator or the location of the tools on the scope of the Work roll to be adjusted.

Der verfahrbare Sitz kann in eine äußere Position vor und seitlich neben das Fahrschiff verfahrbar sein. Hierzu ist die Länge der Gelenkarme so gewählt, dass der Fahrsitz bis ganz nach außen neben die Baumaschine schwenkbar ist. Dies hat den Vorteil, dass die Bedienungsperson bequem an der Seite der Baumaschine ein- oder aussteigen kann.The movable seat can be in an outer position in front of and to the side of the cruise ship be movable. For this purpose, the length of the articulated arms is selected so that the Driving seat can be swiveled all the way to the side next to the construction machine. This has the Advantage that the operator conveniently on or on the side of the construction machine can get out.

An dem Sitz kann ferner noch eine Betätigungseinrichtung für einen Notschalter und/oder eine Beleuchtungseinrichtung und/oder eine Signaleinrichtung, z.B. eine Hupe angeordnet sein.An actuating device for an emergency switch can also be attached to the seat and / or a lighting device and / or a signal device, e.g. a Horn be arranged.

Mit Hilfe des Hilfsantriebs wird dann die Arbeitswalze um einen fest vorgegebenen, aber variabel einstellbaren Drehwinkel verdreht.With the help of the auxiliary drive, the work roll is then moved around a fixed, but rotated variably adjustable rotation angle.

Der Motor des Hilfsantriebs ist vorzugsweise nur bei ausgeschalteter Schaltkupplung für die Arbeitswalze einschaltbar. The motor of the auxiliary drive is preferably only when the clutch is switched off switchable for the work roll.

Der Sitz kann gemäß einem weiteren Ausführungsbeispiel an einer an dem Maschinenrahmen oder an einem der Fahrschiffe gelagerten Stange teleskopierbar befestigt sein. In diesem Fall wird der Sitz nur linear in Richtung auf die Arbeitswalze oder zurückbewegt, kann aber auch am Ende der Stange gelenkig oder über einen Gelenkarm mit dieser verbunden sein.According to a further exemplary embodiment, the seat can be attached to one of the machine frames or attached telescopically to one of the runners mounted rod his. In this case the seat is only linear towards the work roll or moved back, but can also be articulated at the end of the rod or over one Articulated arm to be connected to this.

Im Folgenden werden unter Bezugnahme auf die Zeichnungen Ausführungsbeispiele der Erfindung näher erläutert.Exemplary embodiments are described below with reference to the drawings the invention explained in more detail.

    • Die in Fig. 1 gezeigte Baumaschine 1 ist eine Großfräse mit einem von Fahrschiffen 5 eines höhenverstellbaren Fahrwerks 2 getragenen Maschinenrahmen 4. Der Maschinenrahmen 4 weist eine zwischen den Fahrschiffen 5 angeordnete, an dem Maschinenrahmen 4 gelagerte Arbeitswalze 8 mit aus Fräsmeißeln bestehenden Werkzeugen 14 zum Abarbeiten eines Fahrbahnbelages auf. Die auswechselbaren Werkzeuge 14 sind auf der Mantelfläche der Arbeitswalze 8 in einem vorgegebenen Muster angeordnet. Ein Antriebsstrang 18 treibt die Arbeitswalze 8 an. Zu dem Antriebsstrang 18 gehören zumindest ein Antriebsmotor 6, sowie ein mit dem Antriebsmotor 6 gekoppeltes Riemengetriebe 16. Das Riemengetriebe 16 besteht aus einer motorseitigen Riemenscheibe 28 und einer walzenseitigen Riemenscheibe 24, die mit mindestens einem Antriebsriemen 30 miteinander gekoppelt sind. Der Antriebsriemen 30 ist vorzugsweise aus Keilriemen zusammengesetzt.The construction machine 1 shown in FIG. 1 is a large milling machine with one of vehicles 5 of a height-adjustable undercarriage 2 carried machine frame 4. The machine frame 4 has one arranged on the machine frame between the ships 5 4 mounted work roll 8 with tools consisting of milling chisels 14 to process a road surface. The interchangeable tools 14 are on the outer surface of the work roll 8 in a predetermined Pattern arranged. A drive train 18 drives the work roll 8. To the drivetrain 18 include at least one drive motor 6 and one with the drive motor 6 coupled belt transmission 16. The belt transmission 16 consists of an engine-side pulley 28 and a roller-side pulley 24, which are coupled to one another with at least one drive belt 30. The drive belt 30 is preferably composed of V-belts.

    Aus Fig. 1 ist ein mit dem Riemengetriebe 16 koppelbarer Hilfsantrieb 20 ersichtlich. Der Antriebsriemen 30 läuft über die motorseitige Riemenscheibe 28, über eine von einer Spanneinrichtung andrückbare Spannrolle 38 und über die walzenseitige Riemenscheibe 24 um. An der walzenseitigen Riemenscheibe 24 ist eine Reibrolle 34 des Hilfsantriebs 20 über eine Stelleinrichung 37 andrückbar, wodurch der Hilfsantrieb 20 ein Drehmoment auf die walzenseitige Riemenscheibe 24 übertragen kann. Die Reibrolle 34 hat den Vorteil, dass das übertragbare Drehmoment begrenzt ist. Bei einer Blockade der Arbeitswalze 8 würde die Reibrolle 34 letztlich auf der Riemenscheibe 24 durchrutschen, wodurch eine Unfallgefahr praktisch ausgeschlossen ist.1 shows an auxiliary drive 20 which can be coupled to the belt transmission 16. The drive belt 30 runs over the engine-side pulley 28, via one of a tensioning device pressable tensioning roller 38 and the roller-side pulley 24 um. A friction roller 34 is on the roller-side pulley 24 of the auxiliary drive 20 can be pressed on via an actuating device 37, as a result of which the auxiliary drive 20 can transmit torque to the roller-side pulley 24. The friction roller 34 has the advantage that the transmissible torque is limited. If the work roll 8 were blocked, the friction roller 34 would ultimately be on the belt pulley 24 slip through, which practically eliminates the risk of an accident is.

    Fig. 2 zeigt den Antriebsstrang 18 bestehend aus dem Antriebsmotor 6, der mit einem Pumpenverteilergetriebe 7 gekoppelt sein kann, an dem verschiedene Hydroantriebe für unterschiedliche Funktionen der Baumaschine angeschlossen sein können.Fig. 2 shows the drive train 18 consisting of the drive motor 6, with a Pump transfer case 7 can be coupled to the various hydraulic drives can be connected for different functions of the construction machine.

    Der Antriebsmotor 6 bzw. das Pumpenverteilergetriebe 7 kann über eine Kupplung 9 mit der motorseitigen Riemenscheibe 28 gekoppelt sein. Die Arbeitswalze 8 ist in Wänden des Maschinenrahmens 4 gelagert. In der Arbeitswalze 8 kann ein Untersetzungsgetriebe 25 angeordnet sein, das die Drehzahl der walzenseitigen Riemenscheibe 24 beispielsweise im Verhältnis 1:20 untersetzt. Damit kann die Arbeitswalze 8 mit einer Arbeitsdrehzahl von ca. 100 U/min arbeiten, wenn der Verbrennungsmotor mit einer Drehzahl von ca. 2000 U/min betrieben wird und das Riemengetriebe 16 ein Übersetzungsverhältnis von ca. 1:1 hat.The drive motor 6 or the pump transfer case 7 can be via a clutch 9 can be coupled to the engine-side pulley 28. The work roll 8 is in Walls of the machine frame 4 stored. In the work roll 8, a reduction gear 25 be arranged, the speed of the roller-side pulley 24, for example, in a ratio of 1:20. So that the work roll 8 work at a working speed of approximately 100 rpm when the internal combustion engine is operated at a speed of approx. 2000 rpm and the belt transmission 16 has a gear ratio of approximately 1: 1.

    Die auf der Mantelfläche 12 der Arbeitswalze 8 angeordneten auswechselbaren Werkzeuge 14, z.B. Fräsmeißel, müssen am Ende ihrer Standzeit durch eine Bedienungsperson gegen neue Werkzeuge ausgewechselt werden, wozu die Bedienungsperson durch Öffnen einer Klappe 11 des Walzengehäuses 13 in den Arbeitsraum hinter der Arbeitswalze 8 eintreten kann. An den in Fahrtrichtung hinteren Fahrschiffen 5 ist jeweils ein Sitz 27 über zwei Gelenkarme 29, 31 an Seitenwänden 15 der Fahrschiffe 5 gelenkig um vertikale Achsen gelagert, so dass die Sitze 27 in einer horizontalen zur Achse der Arbeitswalze parallelen Ebene beliebig verschwenkbar sind. The interchangeable arranged on the outer surface 12 of the work roll 8 Tools 14, e.g. Milling chisels must be used by an operator at the end of their service life be replaced with new tools, for which the operator by opening a flap 11 of the roller housing 13 in the work space can occur behind the work roll 8. On the rear-facing ships in the direction of travel 5 is a seat 27 via two articulated arms 29, 31 on side walls 15 of the ships 5 articulated about vertical axes, so that the seats 27 in one horizontal plane parallel to the axis of the work roll can be pivoted as desired are.

    Die Arbeitswalze 8 befindet sich dann in einem angehobenen Zustand, so dass die Werkzeuge 14 nicht im Eingriff mit der Bodenoberfläche sind. Mit Hilfe des Hilfsantriebs 20 kann die Arbeitswalze 8 um einen vorbestimmten Drehwinkel derart verdreht werden, dass eine nächste Reihe von Werkzeugen 14 in eine günstige Montageposition gebracht werden können.The work roll 8 is then in a raised state, so that the Tools 14 are not in engagement with the floor surface. With the help of the auxiliary drive 20, the work roll 8 can be rotated in this way by a predetermined angle of rotation that a next set of tools 14 will be in a convenient mounting position can be brought.

    Die Anordnung der Werkzeuge 14 auf der Mantelfläche 12 der Arbeitswalze 8 ist am besten aus Fig. 3 ersichtlich. Bei der Aktivierung des Hilfsantriebs 20 kann die Arbeitswalze 8 um einen bestimmten Winkelbetrag oder für eine bestimmte Zeitdauer gedreht werden.The arrangement of the tools 14 on the outer surface 12 of the work roll 8 is on best seen in Fig. 3. When the auxiliary drive 20 is activated, the work roll can 8 by a certain angular amount or for a certain length of time be rotated.

    Der Hilfsantrieb 20 weist eine Steuerung auf, die über eine Fernbedienung 33 aktivierbar ist und die Einschaltdauer des Motors steuert. Dabei ist in vorteilhafter Weise vorgesehen, dass bei jeder Aktivierung des Hilfsantriebs durch einen Fernbedienungsschalter die voreingestellte maximale Einschaltdauer und damit eine vorbestimmte maximale Winkeldrehung der Arbeitswalze 8 eingehalten wird.The auxiliary drive 20 has a control that can be activated via a remote control 33 and controls the duty cycle of the motor. It is advantageous provided that each time the auxiliary drive is activated by a remote control switch the preset maximum duty cycle and thus a predetermined one maximum angular rotation of the work roll 8 is observed.

    Wird der Fernbedienungsschalter vor Ablauf der maximalen Einschaltdauer von beispielsweise 4 Sekunden losgelassen, stoppt der Hilfsantrieb 20 vorzeitig.For example, the remote control switch will expire before the maximum duty cycle When released for 4 seconds, the auxiliary drive 20 stops prematurely.

    Vorzugsweise weist der Hilfsantrieb 20 eine Sicherheitsschaltung auf, gemäß der der Motor des Hilfsantriebs 20 nur bei ausgeschaltetem Antriebsmotor 6 einschaltbar ist.The auxiliary drive 20 preferably has a safety circuit according to which the motor of the auxiliary drive 20 can only be switched on when the drive motor 6 is switched off is.

    Desweiteren kann eine Sicherheitsschaltung vorgesehen sein, die den Hilfsantrieb 20 beim Überschreiten eines vorgegebenen maximalen Widerstandsmomentes der Arbeitswalze 8 stoppt.Furthermore, a safety circuit can be provided that the auxiliary drive 20 when a predetermined maximum section modulus is exceeded Work roll 8 stops.

    Die Fernbedienung 33 für den Hilfsantrieb befindet sich vorzugsweise an dem Sitz 27 für die Bedienungsperson. The remote control 33 for the auxiliary drive is preferably located on the seat 27 for the operator.

    Die Fernbedienung 33 kann auch mit einem Magnetfuß versehen sein, wodurch sie beliebig in Reichweite der Bedienungsperson an metallischen Teilen der Baumaschine 1 befestigt werden kann.The remote control 33 can also be provided with a magnetic base, whereby it anywhere within reach of the operator on metallic parts of the construction machine 1 can be attached.

    Die Fernbedienung 33 kann auch eine Betätigungseinrichtung für einen Notschalter und/oder eine Beleuchtungseinrichtung und/oder eine Signaleinrichtung, z.B. eine Hupe, aufweisen.The remote control 33 can also be an actuator for an emergency switch and / or a lighting device and / or a signal device, e.g. a Horn.
