Description
Die Erfindung betrifft einerseits einen Balg zur Reduzierung der Schallemission einer schallemittierenden Einrichtung, umfassend ein Werkzeug und Werkstück, wobei das Werkstück vom Werkzeug bearbeitet wird, wobei der Balg an dem Werkzeug und/oder dem Werkstück anordbar ist, wobei der Balg den schallemittierenden Bereich von Werkzeug und Werkstück zumindest im Wesentlichen umgibt. Die Anmeldung umfasst ebenfalls eine schallemittierende Einrichtung umfassend ein Rammgerät und ein Rammglied mit einem Wellenbalg.The invention relates on the one hand to a bellows for reducing the acoustic emission of a sound emitting device, comprising a tool and workpiece, wherein the workpiece is machined by the tool, wherein the bellows on the tool and / or the workpiece can be arranged, wherein the bellows the sound emitting area of the tool and workpiece at least substantially surrounds. The application also includes a sound emitting device comprising a pile driver and a ram member with a bellows.
Schallemittierende Einrichtungen sind aus dem Stand der Technik bekannt. So sind z. B. Rammgeräte zum Eintreiben eines Rammpfahles oder einer Spundbohle in den Boden bekannt.Sound emitting devices are known in the art. So z. As piling equipment for driving a pile pile or a sheet pile in the ground known.
Das Rammgerät selbst ist hierbei durch den Ausleger z. B. eines Fahrzeugs in vertikaler Richtung verschieblich gehalten. Geführt wird das Rammgerät durch einen Führungspfahl, der ebenfalls von dem Ausleger des Fahrzeugs gehalten wird. Das Rammgerät selbst besitzt eine Pfahlhaube, wobei die Pfahlhaube als Teil des Rammgerätes oben auf dem Pfahl aufsitzt.The pile driver itself is in this case by the boom z. B. a vehicle held displaceably in the vertical direction. The pile driver is guided by a guide pole, which is also held by the boom of the vehicle. The piling device itself has a pile cap, the pile cap sits as part of the pile driver on top of the post.
Das Eintreiben von Rammpfählen in den Boden ist mit einer erheblichen Schallemission verbunden. Insofern ist auch bereits aus der
Die der Erfindung zugrunde liegende Aufgabe besteht darin, bei schallemittierenden Einrichtungen eine signifikante Reduktion der Schallemission zu erzielen, wobei dies mit möglichst einfachen Mitteln bewerkstelligt werden soll.The object underlying the invention is to achieve a significant reduction of the acoustic emission in sound-emitting devices, which is to be accomplished with the simplest possible means.
Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, dass der Balg als Wellenbalg ausgebildet ist. Ein Wellenbalg ist ähnlich einfach aufgebaut wie ein Faltenbalg, sorgt jedoch für eine wesentlich höhere Schallabsorption.To achieve the object, the invention proposes that the bellows is designed as a bellows. A bellows is as simple as a bellows, but provides a much higher sound absorption.
Vorteilhafte Merkmale und Ausgestaltungen ergeben sich aus den Unteransprüchen.Advantageous features and embodiments will become apparent from the dependent claims.
So ist insbesondere vorgesehen, dass der Balg mehrere in Reihe angeordnete im Querschnitt wellenförmige Elemente umfasst, die im Bereich des Übergangs von einem wellenförmigen Element zu einem benachbarten wellenförmigen Element miteinander verbunden sind; die wellenförmigen Elemente sind hierbei ringförmig geschlossen. Hieraus wird deutlich, dass ein Wellenbalg aus mehreren im Querschnitt wellenförmigen Elementen ausgebildet ist, die in Reihe zueinander angeordnet sind und die untereinander durch Nähen und/oder Kleben miteinander verbunden sind, wobei die wellenförmigen Elemente zur auf dem Umfang geschlossenen Ummantelung der schallemittierenden Einrichtung ebenfalls ringförmig geschlossen sind.Thus, it is provided in particular that the bellows comprises a plurality of elements arranged in series in the form of corrugations which are connected in the region of the transition from a wave-shaped element to an adjacent wave-shaped element; the wave-shaped elements are closed annularly. From this it is clear that a bellows is formed of a plurality of corrugated in cross-section elements which are arranged in series and which are interconnected by sewing and / or gluing together, wherein the wave-shaped elements to the circumferentially closed shell of the sound emitting device also annular are closed.
Zur Erhöhung der Stabilität eines solchen Balges ist vorgesehen, dass im Bereich der Verbindung der wellenförmigen Elemente untereinander jeweils zwei Wellenelemente erfassende im Querschnitt in etwa U-förmige Einfassrahmen vorgesehen sind. Die Einlassrahmen sind hierbei ringförmig umlaufend ausgebildet. Durch die Einfassrahmen ergibt sich nicht nur eine stabilere Verbindung zweier wellenförmiger Elemente, vielmehr erhält der Balg insgesamt eine höhere Stabilität, und zwar insbesondere gegen Ausknicken.In order to increase the stability of such a bellows, it is provided that in the region of the connection of the wave-shaped elements in each case two shaft elements detecting in cross-section in approximately U-shaped border frame are provided. The inlet frame are in this case formed annularly encircling. The bordering frame not only results in a more stable connection of two wave-shaped elements, but rather gives the bellows a higher overall stability, in particular against buckling.
Als besonders vorteilhaft hat sich herausgestellt, wenn die wellenförmigen Elemente in Richtung auf das Innere des Balges zugewölbt sind. So konnte mit einem solchermaßen ausgebildeten Balg eine Schallabsorptionsdifferenz um 4 dB zwischen einem Faltenbalg und einem Wellenbalg mit solchen mit nach innen gewölbten Wellen erzielt werden.It has proven to be particularly advantageous if the wave-shaped elements are arched toward the interior of the bellows. Thus, a sound absorption difference of 4 dB between a bellows and a bellows with those with inwardly curved waves could be achieved with such a bellows.
Nach einem besonderen Merkmal der Erfindung ist das ringförmige im Querschnitt wellenförmige Element aus mindestens zwei Ringsegmenten ausgebildet, wobei die beiden Ringsegmente miteinander verbunden sind; die Verbindung kann hierbei durch Vernähen und/oder Verkleben erfolgen. Dies hat Vorteile in Bezug auf den Herstellungsprozess, wie sich dies aus den nachstehenden Erläuterungen ergibt.According to a particular feature of the invention, the annular corrugated element in cross section is formed from at least two ring segments, wherein the two ring segments are interconnected; the connection can be made by sewing and / or gluing. This has advantages in terms of the manufacturing process, as will be apparent from the following explanations.
So ist nach einem weiteren Merkmal der Erfindung vorgesehen, dass das wellenförmige Element mindestens einen mit einem Elastomer beschichteten Festigkeitsträger aufweist, wobei der Festigkeitsträger vorteilhaft als Stoff, insbesondere als Gewebe ausgebildet ist. Das im Querschnitt wellenförmige Element weist zwei Schenkelbereiche und einen Stegbereich auf. Für den Aufbau eines im Querschnitt wellenförmigen Elementes ist vorgesehen, dass im Schenkelbereich jeweils eine erste und eine zweite Schenkelbahn aus einem mit einem Elastomer beschichteten Festigkeitsträger vorgesehen ist, wobei die beiden Schenkelbahnen durch eine Stegbahn aus ebenfalls mit einem Elastomer beschichteten Festigkeitsträger verbunden sind. Die Verbindung erfolgt hierbei ebenfalls vorteilhaft durch Verkleben und/oder Vernähen. Insbesondere hat sich herausgestellt, dass die Herstellung der Wellenform bei einem Ringsegment, z. B. einem halbkreisförmigen Ringsegment, besonders einfach zu bewerkstelligen ist. Dies insofern, als keine kreisförmigen Bahnen für den Schenkelbereich vorbereitet werden müssen, sondern lediglich halbkreisförmige Bahnen. Dies ist nicht nur einfacher, sondern spart auch Material.Thus, according to a further feature of the invention, it is provided that the wave-shaped element has at least one strength carrier coated with an elastomer, wherein the strength carrier is advantageously designed as a material, in particular as a fabric. The corrugated element has two leg portions and a land portion. For the construction of a corrugated element in cross-section is provided that in the leg region in each case a first and a second leg web is provided from a coated elastomer with a reinforcement, wherein the two leg webs are connected by a web web also coated with an elastomer reinforcement. The connection takes place here also advantageously by gluing and / or sewing. In particular, it has been found that the production of the waveform in a ring segment, z. B. a semi-circular ring segment, is particularly easy to accomplish. This insofar as no circular tracks need to be prepared for the leg area, but only semi-circular tracks. This is not only easier, but also saves material.
Gegenstand der Erfindung ist ebenfalls eine schallemittierende Einrichtung umfassend ein Rammgerät und ein Rammglied, z. B. einen Rammpfahl oder eine Spundbohle, mit einem Wellenbalg, wie er zuvor beschrieben worden ist. Das Rammgerät bildet hierbei das Werkzeug, das Rammglied das Werkstück. Der Wellenbalg ist nach einem Merkmal durch mindestens einen Halter mit dem Rammglied oder dem Rammgerät und hier insbesondere der Rammhaube des Rammgerätes verbunden. Von Vorteil ist, wenn die Rammhaube des Rammgerätes, die das Ende des Rammpfahles oder der Spundbohle napfartig umgibt, mit dem Wellenbalg verbunden ist. Dies insofern, als dann ein im Wesentlichen dichter Abschluss im oberen Endbereich des Rammpfahles erreicht werden kann. Der Halter kann hierbei vorteilhaft durch den oberen, letzten Einfassrahmen des Wellenbalgs gebildet werden, der insofern an der Stirnseite der Rammhaube zum Rammglied angeschraubt sein kann. Der obere Einfassrahmen erfasst dann allerdings lediglich eine Schenkelbahn. Am unteren Ende kann entsprechend ebenfalls ein Einfassrahmen vorgesehen sein, mit dem der Wellenbalg auf dem Boden aufsteht und insofern der Verschleiß des Balges an sich in diesem Bereich vermindert ist. Hieraus wird deutlich, dass durch einen im Querschnitt ringförmigen Balg während des Eintreibens eines Rammgliedes in den Boden, durch den Wellenbalg der schallemittierende Bereich von Rammgerät und Rammpfahl oder Spundbohle nicht nur tangential umlaufend eingehaust ist, sondern auch über die Länge des Rammgliedes. Das insofern, als der Wellenbalg, der vorteilhaft an der Stirnseite der Rammhaube befestigt ist, über die Länge des Rammgliedes gezogen wird und schlussendlich der Wellenbalg mit seinem unteren Ende auf dem Boden aufsteht. Entsprechend dem Rammfortschritt verkürzt sich der Wellenbalg sukzessive.The invention is also a sound-emitting device comprising a piling device and a piling member, for. As a driven pile or a sheet pile, with a bellows, as has been previously described. The pile driver here forms the tool, the piling member the workpiece. The bellows is connected to a feature by at least one holder with the piling member or piling device and here in particular the Rammhaube the pile driver. It is advantageous if the Rammhaube the pile driver, the end of the Rammpfahles or the sheet pile surrounds cup-shaped, is connected to the bellows. This insofar as then a substantially close completion in the upper end of the pile can be achieved. The holder can be advantageously formed by the upper, last frame of the bellows, which may be screwed to the Rammglied on the front side of the Rammhaube. However, the upper border frame then only detects one leg track. At the lower end may also be provided according to a border frame with which the bellows rests on the ground and thus the wear of the bellows is reduced in this area in itself. It is clear that is surrounded by a ring-shaped in cross section bellows during the driving of a piling member in the ground, through the bellows of the sound emitting area of piling and driven pile or sheet pile not only tangentially circumferentially, but also over the length of the Rammgliedes. This insofar as the bellows, which is advantageously attached to the front side of the driving hood, is pulled over the length of the piling member and finally the shaft bellows with its lower end rests on the ground. According to the piling progress, the bellows shortens gradually.
