Description

Baumaschine mit beheizbarer Materialtransportvorrichtung  Construction machine with heatable material transport device
Die vorliegende Erfindung bezieht sich auf eine Baumaschine gemäß dem Oberbegriff des Anspruchs 1. The present invention relates to a construction machine according to the preamble of claim 1.
Beispiele für solche Baumaschinen sind Straßenfertiger sowie Beschicker zum Versorgen solcher Straßenfertiger mit Einbaumischgut. Mittels eines Antriebs kann die Baumaschine selbstfahrend sein. Eine Heizeinrichtung verhindert ein zu frühes und zu schnelles Abkühlen des transportierten Materials durch den Kontakt mit der Materialtransportvorrichtung bzw. während des Transports auf der Materialtransportvorrichtung. Indem das Material auf einer höheren Temperatur gehalten wird, verlängert sich die Zeit, die zum Verarbeiten des transportierten Materials (beispielsweise bituminösem Einbaumischgut) zur Verfügung steht. Examples of such construction machines are pavers and feeders for supplying such road pavers with Einbaumischgut. By means of a drive, the construction machine can be self-propelled. A heater prevents too early and too fast cooling of the transported material by the contact with the material handling device or during transport on the material handling device. By keeping the material at a higher temperature, the time available for processing the transported material (for example, bituminous built-in material) is increased.
Bereits bekannt ist die Verwendung einer Oasheizung oder elektrischer Heizelemente als Heizeinrichtung zum Beheizen einer Materialtransportvorrichtung. Beide Varianten haben jedoch Nachteile. Eine Gasheizung ist nachteilig, da das Gas beispielsweise in Flaschen auf der Baumaschine gelagert werden muss. Es besteht die Gefahr, dass diese Flaschen während des Betriebs der Baumaschine geleert werden, ohne dass dies rechtzeitig erkannt wird. Zudem beanspruchen die Gasflaschen Platz auf der Baumaschine. Elektrische Heizelemente hingegen sind nachteilig, da zu ihrem Betrieb Verbrennungsenergie in elektrische Energie umgewandelt werden muss. Der Wirkungsgrad elektrischer Heizelemente ist daher sehr niedrig. Already known is the use of an Oasheizung or electrical heating elements as a heater for heating a material handling device. Both variants have disadvantages. A gas heater is disadvantageous because the gas must be stored, for example, in bottles on the construction machine. There is a risk that these bottles will be emptied during operation of the construction machine, without this being recognized in time. In addition, the gas cylinders take up space on the construction machine. On the other hand, electrical heating elements are disadvantageous since combustion energy has to be converted into electrical energy for their operation. The efficiency of electrical heating elements is therefore very low.
Aufgabe der vorliegenden Erfindung ist es, eine Baumaschine mit konstruktiv möglichst einfachen Mitteln dahingehend zu verbessern, dass eine effizientere Beheizung der Materialtransportvorrichtung ermöglicht wird. Object of the present invention is to improve a construction machine with structurally simple means to the effect that a more efficient heating of the material handling device is made possible.
Diese Aufgabe wird gelöst durch eine Baumaschine mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Ansprüchen angegeben. This object is achieved by a construction machine with the features of claim 1. Advantageous developments of the invention are specified in the claims.
In der erfindungsgemäßen Baumaschine ist oder umfasst die Heizeinrichtung eine Strahlungsheizung, die mittels des selben Kraftstoffs wie der Antrieb der Baumaschine betreibbar ist. Auf diese Weise entfällt die Notwendigkeit, auf der Baumaschine einen ersten Kraftstoff für den Antrieb und einen zweiten Kraftstoff oder ein anderes Betriebsmittel für die Heizeinrichtung bevorraten zu müssen. In the construction machine according to the invention, the heating device is or comprises a radiant heater, which can be operated by means of the same fuel as the drive of the construction machine. This eliminates the need for a first on the construction machine To store fuel for the drive and a second fuel or other resources for the heater.
Bei dem Antrieb der Baumaschine kann es sich beispielsweise um einen Diesel- Verbrennungsmotor handeln. Die Heizeinrichtung kann dann auch eine Strahlungsheizung mit einem Dieselbrenner sein. Diesel wird dabei also sowohl für den Antrieb, als auch für die Heizeinrichtung verwendet. The drive of the construction machine may be, for example, a diesel internal combustion engine. The heater can then also be a radiant heater with a diesel burner. Diesel is thus used both for the drive, as well as for the heater.
Besonders günstig ist es, wenn der Kraftstoff in einem gemeinsamen Tank sowohl für den Antrieb, als auch für den Brenner der Heizeinrichtung bevorratet ist. Damit ist sichergestellt, dass während der gesamten Betriebsdauer der Baumaschine ausreichend Kraftstoff zum Betreiben der Heizeinrichtung vorhanden ist. Denkbar wäre es, an solch einem Tank eine Tankanzeige vorzusehen, mittels derer der Bediener der Baumaschine über den Füllstand des Tanks informiert wird. It is particularly favorable if the fuel is stored in a common tank both for the drive and for the burner of the heating device. This ensures that sufficient fuel is available for operating the heating device during the entire operating period of the construction machine. It would be conceivable to provide a fuel gauge on such a tank, by means of which the operator of the construction machine is informed about the fill level of the tank.
Besonders komfortabel wird der Betrieb der Baurnaschine, wenn die Heizeinrichtung von einem Steuerstand der Baumaschine aus bedienbar ist. Insbesondere könnte die Heizeinrichtung von diesem Steuerstand ein- oder ausgeschaltet sowie in ihrer Heizleistung verändert werden. Gegenüber herkömmlichen Gasheizungen für Förderbänder entfällt damit die Notwendigkeit, direkten Zugang zu den Brennstellen der Gasheizung zu haben, die Glühstifte vor der Inbetriebnahme vorzugehen, die Flamme zu entzünden und den Brennvorgang vom Bediener zu kontrollieren. Operation of the construction machine becomes particularly comfortable when the heating device can be operated from a control station of the construction machine. In particular, the heater of this control station could be switched on or off and changed in their heating power. Compared with conventional gas heaters for conveyor belts eliminates the need to have direct access to the burners of the gas heater, proceed the glow plugs before commissioning, ignite the flame and control the burning process by the operator.
Vorzugsweise sind Mittel zum Abschalten der Heizeinrichtung bei Stillstand der Materialtransportvorrichtung vorgesehen. Damit wird die Gefahr einer Überhitzung der beheizten Bereiche der Materialtransportvorrichtung vermieden, durch die die Materialtransportvorrichtung andernfalls beschädigt werden könnte. Preferably, means for switching off the heating device are provided when the material transport device is at a standstill. This avoids the risk of overheating of the heated areas of the material handling apparatus, which could otherwise damage the material handling apparatus.
An der Materialtransportvorrichtung oder in deren Nähe kann ein Temperatursensor vorgesehen sein, um die Temperatur der Materialtransportvorrichtung zu kontrollieren und Überhitzungszustände rechtzeitig erkennen zu können. At the material transport device or in the vicinity of a temperature sensor may be provided to control the temperature of the material handling device and to recognize overheating conditions in time.
In einer vorteilhaften Ausführungsvariante der Erfindung ist eine Steuerung vorgesehen und dazu konfiguriert, die Heizeinrichtung in Abhängigkeit von der gemessenen Temperatur der Materialtransportvorrichtung zu steuern. Wenn die Materialtransportvorrichtung zu kalt wird, wird die Heizleistung erhöht. Umgekehrt kann die Heizleistung gesenkt werden, wenn eine zu hohe Temperatur der Materialtransportvorrichtung oder des darauf transportierten Materials gemessen wird und möglicherweise eine Überhitzung droht. In an advantageous embodiment of the invention, a controller is provided and configured to control the heater in dependence on the measured temperature of the material transport device. When the material handling device to is cold, the heating power is increased. Conversely, the heating power can be lowered if too high a temperature of the material transport device or of the material transported on it is measured and possibly overheating is imminent.
Die erfindungsgemäße Baumaschine kann insbesondere als Straßenfertiger ausgebildet sein, oder als Beschickungsfahrzeug zum Versorgen solch eines Straßenfertigers mit heißem Einbaumischgut. The construction machine according to the invention can be designed in particular as a road paver, or as a feed vehicle for supplying such a paver with hot Einbaumischgut.
Im Folgenden wird ein vorteilhaftes Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher dargestellt. Die einzige Figur zeigt in schematischer Seitenansicht einen Beschicker für einen Straßenfertiger als Ausführungsbeispiel einer erfindungsgemäßen Baumaschine 1. Das Beschickungsfahrzeug umfasst ein Fahrwerk, hier ein Ketten- Fahrwerk, das mittels eines Diesel-Verbrennungsmotors als Antrieb der Baumaschine 1 betreibbar ist. Ein Gutbunker 3 an dem in Arbeitsrichtung vorderen Ende der Baumaschine 1 dient zur Aufnahme und zum Speichern von Material, in diesem Fall von Einbaumischgut. Mit einer als Förderband ausgebildeten Materialtransportvorrichtung 4 kann das Material aus dem Gutbunker 3 zum hinteren Ende der Baumaschine 1 transportiert werden. Das Förderband 4 steigt dabei an. In the following, an advantageous embodiment of the invention is illustrated in more detail with reference to a drawing. The single FIGURE shows a schematic side view of a feeder for a paver as an embodiment of a construction machine according to the invention 1. The charging vehicle comprises a chassis, here a chain chassis, which is operated by means of a diesel internal combustion engine as the drive of the construction machine 1. A Gutbunker 3 at the front in the direction of the construction machine 1 is used for receiving and storing material, in this case of Einbaumischgut. With a material handling device 4 designed as a conveyor belt, the material can be transported out of the goods bunker 3 to the rear end of the construction machine 1. The conveyor belt 4 increases thereby.
In einem Tank 4 der Baumaschine 1 ist Diesel zum Betreiben des Antriebs der Baumaschine 1 bevorratet. Eine Tankanzeige (nicht dargestellt) zeigt dem Bediener auf einem Steuerstand den Füllstand des Tanks 4 an. In a tank 4 of the construction machine 1 diesel is stored for operating the drive of the construction machine 1. A fuel gauge (not shown) indicates to the operator on a control station the level of the tank 4.
Über eine Leitung 5 wird der im Tank gespeicherte Kraftstoff einer Heizeinrichtung 6 zugeführt, die oberhalb der Materialtransportvorrichtung 4 angeordnet ist und diese von oben beheizt. Via a line 5, the fuel stored in the tank is fed to a heating device 6, which is arranged above the material transport device 4 and heats it from above.
Die Heizeinrichtung 7 ist im vorliegenden Ausführungsbeispiel als Direktstrahlungsheizung mit Dieselbrennereinheit ausgebildet. Über die Leitung 6 wird der Kraftstoff aus dem Tank 5 der Dieselbrennereinheit 8 der Heizeinrichtung zugeführt. Durch Verbrennung des Dieselkraftstoffes aus dem Tank 5 erzeugt die Dieselbrennereinheit 8 Wärme. Ein durch diese Wärme erhitztes Medium wird durch Wärmeleiter 9 der Heizeinrichtung 7 geführt. Von den Wärmeleitern .9 wird Strahlungswärme 10 nach unten an die Materialtransporteinrichtung 4 bzw. an das darauf transportierte Material abgegeben. In der Nähe der Materialtransportvorrichtung 4, beispielsweise direkt oberhalb der Materialtransportvorrichtung 4, ist ein Temperatursensor 11 vorgesehen. Dieser Temperatursensor 11 misst die Temperatur der Materialtransportvorrichtung 4 und/oder des darauf transportierten Materials. Die Messwerte werden an eine Steuerung übermittelt, die auch den Betrieb der Heizeinrichtung 7 steuert. Bei Gefahr einer Überhitzung wird die Heizleistung der Heizeinrichtung 7 abgesenkt. The heater 7 is formed in the present embodiment as a direct radiation heater with diesel burner unit. Via the line 6, the fuel from the tank 5 of the diesel burner unit 8 is supplied to the heater. By burning the diesel fuel from the tank 5, the diesel burner unit 8 generates heat. A heated by this heat medium is passed through heat conductor 9 of the heater 7. Radiant heat 10 is emitted downwards by the heat conductors .9 to the material transport device 4 or to the material transported thereon. In the vicinity of the material transport device 4, for example, directly above the material transport device 4, a temperature sensor 11 is provided. This temperature sensor 11 measures the temperature of the material transport device 4 and / or the material transported thereon. The measured values are transmitted to a controller, which also controls the operation of the heating device 7. At risk of overheating, the heating power of the heater 7 is lowered.
Das Einschalten der Heizeinrichtung und die Kontrolle des Brennvorgangs erfolgt von einem Steuerstand der Baumaschine aus, ohne dass der Bediener direkten Zugang und Sichtkontakt zur Heizeinrichtung 7 benötigt. Der Betrieb der Heizeinrichtung 7 kann auch an die Bewegung der Materialtransportvorrichtung 7 gekoppelt sein. Wenn ein Stillstand der Materialtransportvorrichtung 4 eintritt, sei es gewünscht oder durch einen Defekt, wird die Heizeinrichtung 7 abgeschaltet, um eine Überhitzung der Materialtransportvorrichtung 4 zu vermeiden. Beispielsweise kann dafür ein Absperrventil in der Leitung 7 geschlossen werden. The switching on of the heating device and the control of the burning process takes place from a control station of the construction machine, without the operator needing direct access and visual contact with the heating device 7. The operation of the heating device 7 may also be coupled to the movement of the material transport device 7. When a standstill of the material handling device 4 occurs, whether desired or due to a defect, the heater 7 is turned off to prevent overheating of the material handling device 4. For example, a shut-off valve in line 7 can be closed for this purpose.
Mittels des Temperatursensors 11 ist eine Überwachung und Regelung der Temperatur der Materialtransportvorrichtung 4 möglich. Zudem kann ein Aufwärm prozess vollautomatisch überwacht werden, ohne dass ein Sichtkontakt des Bedieners zur Heizeinrichtung 7 erforderlich ist. By means of the temperature sensor 11 is a monitoring and control of the temperature of the material handling device 4 possible. In addition, a warm-up process can be monitored fully automatically, without a visual contact of the operator to the heater 7 is required.
Ausgehend von dem dargestellten Ausführüngsbeispiel kann die erfindungsgemäße Baumaschine 1 in verschiedener Weise verändert werden. Beispielsweise könnte eine Förderschnecke anstelle eines Förderbandes als Materialtransportvorrichtung 4 vorgesehen werden. Die Heizeinrichtung 7 könnte auch unterhalb oder innerhalb der Materialtransportvorrichtung 4 angeordnet sein, beispielsweise zwischen dem Obertrum und dem Untertrum des Förderbandes 4. Starting from the illustrated embodiment, the construction machine 1 according to the invention can be modified in various ways. For example, a screw conveyor could be provided instead of a conveyor belt as a material transport device 4. The heating device 7 could also be arranged below or inside the material transport device 4, for example between the upper strand and the lower strand of the conveyor belt 4.
