Description
Randabschneidemaschine für bituminöse Fahrbahnbeläge Die Erfindung betrifft eine Randabschneidemaschine für bituminöse Fahrbahnbeläge, insbesondere aus Asphaltbeton, die ein auf Rädern laufendes Fahrgestell und ein an diesem angeordnetes Schlagwerkzeug aufweist, das durch von einem Motor angetriebene Mittel periodisch in gegen den Belag gerichtete Schlagbewegungen versetzt wird.Edge cutting machine for bituminous road surfaces The invention relates to an edge cutting machine for bituminous road surfaces, in particular made of asphalt concrete, which has a chassis running on wheels and a mounted on it Having impact tool that periodically by means driven by a motor is set in striking movements directed against the surface.
Beim Aufbringen und anschließenden Walzen von bituminösen Fahrbahnbelägen treten zwangläufig Randunregelmäßigkeiten auf; die unregelmäßigen Ränder werden nachträglich gerade geschnitten, damit sie parallel zur Längsrichtung der Fahrbahn verlaufen und von einem gegebenenfalls vorhandenen Bordstein oder sonstigen seitlichen Abschluß einen gleichbleibenden Abstand haben.When applying and then rolling bituminous road surfaces edge irregularities inevitably occur; the irregular edges will be subsequently cut straight so that they are parallel to the longitudinal direction of the roadway run and from a possibly existing curb or other lateral Have a constant distance between the ends.
Es sind schon verschiedene Vorschläge bekanntgeworden, um das Abschneiden maschinell durchzuführen. So ist eine Randabschneidemaschine bekannt, die ein auf Rädern laufendes Fahrgestell aufweist, an dem ein Meißel senkrecht zur Fahrbahn verschiebbar gelagert ist. Der Meißel ist an einer Blattfeder angeschlossen, durch die er periodisch in eine Schlagbewegung nach unten versetzt wird. Hierzu wird die Blattfeder durch einen von einem Motor angetriebenen Nocken periodisch angehoben. Nach dem Anheben drückt sie den Meißel schlagartig gegen den Fahrbahnbelag.Various proposals have already been made known about the cutting off to be carried out automatically. So an edge trimming machine is known that a Has wheels running chassis on which a chisel perpendicular to the roadway is slidably mounted. The chisel is attached to a leaf spring, through which he is periodically put in a flapping movement downwards. For this purpose, the Leaf spring raised periodically by a cam driven by a motor. After lifting it presses the chisel suddenly against the road surface.
Der verhältnismäßig schmale Meißel nutzt sich schnell ab und muß daher oft erneuert werden. Außerdem ist es nur schwer möglich, mit der gespannten Blattfeder eine ausreichende Schlagkraft am Meißel zu erzeugen; denn hierzu ist ein schweres Fahrgestell erforderlich, da die Federspannung der Blattfeder im Fahrgestell aufgenommen werden muß.The relatively narrow chisel wears out quickly and must therefore often renewed. In addition, it is difficult to do with the tensioned leaf spring generate sufficient impact force on the chisel; because this is a difficult one Chassis required because the spring tension of the leaf spring is absorbed in the chassis must become.
Des weiteren ist es bekannt, zum Abschneiden ein Schneidrad zu benutzen, das aus einer runden, an ihrem Umfang mit einer Schneide versehenen Scheibe besteht und um eine waagerechte Achse rehbar ist. Das.Schneidrad wird durch das Gewicht eines Fahrzeuges, z. B. einer Walze, an dem es angeordnet ist, in den Fahrbahnbelag gedrückt. Zum Eindrücken des Schneidrades ist ein großes Gewicht erforderlich. Außerdem läßt sich mit ihm, beispielsweise in Kurven, ein genauer Schnitt nicht ausführen.It is also known to use a cutting wheel for cutting, which consists of a round disc with a cutting edge on its circumference and is rotatable about a horizontal axis. Das.Schneidrad is made by the weight a vehicle, e.g. B. a roller on which it is arranged, in the road surface pressed. Great weight is required to push in the cutting wheel. aside from that a precise cut cannot be made with it, for example in curves.
Der Erfindung liegt die Aufgabe zugrunde, eine Maschine der zuerst genannten Art so zu verbessern, daß ihr Schneidwerkzeug eine längere Lebensdauer hat und daß mit einer verhältnismäßig geringen Eigenmasse eine große Schlagkraft erzeugt wird, ohne daß das Fahrgestell selbst große bauliche Aufwendungen erfordert.The invention is based on the object of a machine of the first to improve said type so that your cutting tool has a longer service life has and that with a relatively low net weight a great impact is generated without the chassis itself requiring major structural expenditures.
Die Lösung dieser Aufgabe besteht nach der Erfindung darin, daß das Schlagwerkzeug durch ein sich in dem Fahrbahnbelag abwälzendes Schneidrad gebildet ist, das durch eine von dem Motor angetriebene Unwucht in die Schlagbewegung versetzt wird.The solution to this problem is according to the invention that the Impact tool formed by a cutting wheel rolling in the road surface which is set in the striking movement by an imbalance driven by the motor will.
Bei der Maschine nach der Erfindung bleibt das Schneidrad in an sich bekannter Weise in ständigem Eingriff mit dem Fahrbahnbelag, so daß ein glatter Schnitt ohne Absätze und Stufen gewährleistet ist. Da sich das Schneidrad in dem Fahrbahnbelag stetig abwälzt, also immer wieder andere Teile der Schneide zum Schneiden verwendet werden, tritt eine Abnutzung in an sich ebenfalls bekannter Weise erst nach längerer Zeit als bei einem Meißel ein. Die rotierende Unwucht übt auf das Schneidrad einen starken Schlag nach dem Vorschlaghammerprinzip aus, das man physikalisch etwa so erklären kann, daß die der Unwucht erteilte kinetische Energie auf dem sehr kleinen Eindringweg des Schneidrades in den Fahrbahnbelag verbraucht wird, folglich also eine sehr große Kraft wirksam wird. Die große Kraft kann erzeugt werden, ohne daß eine übermäßig starke Fahrgestellkonstruktion erforderlich ist, da keine inneren Kräfte im Fahrgestell aufgenommen werden müssen.In the machine according to the invention, the cutting wheel remains in itself known way in constant engagement with the road surface, so that a smooth Cut without heels and steps is guaranteed. Since the cutting wheel is in the Road surface continuously rolling off, so always other parts of the cutting edge to be cut are used, wear only occurs in a manner which is also known per se after a longer time than with a chisel. The rotating imbalance exerts on that Cutting wheel a strong blow on the sledgehammer principle, which one physically can be explained roughly as follows: the kinetic energy imparted to the unbalance on the very small penetration path of the cutting wheel is consumed in the road surface, consequently so a very great force is at work. The great power can be generated without that an excessively strong chassis structure is required, since no internal Forces in the chassis must be absorbed.
Die Verwendung eines Schneidrades als Schlagwerkzeug erscheint ungewöhnlich, weil man bei Schlagwerkzeugen in der Regel das Bestreben hat, die Verwendung von Drehlagern im Übertragungsweg der Schlagkraft zu vermeiden. Im vorliegenden Fall wird der zum schlagunempfindlichen Lagern des Schneidrades etwas. erhöhte Bauaufwand jedoch durch die vorstehend angegebenen Vorteile weit ausgeglichen.The use of a cutting wheel as a striking tool seems unusual, because with striking tools one generally strives to use Avoid pivot bearings in the transmission path of the impact force. In the present case becomes something for the impact-insensitive bearing of the cutting wheel. increased construction costs but far outweighed by the advantages given above.
Weitere Merkmale der Erfindung sind Gegenstand der Unteransprüche.Further features of the invention are the subject of the subclaims.
