Definitions
- the invention relates to a vibration generator, comprising two, three or four wave groups, on which at least two imbalance groups are arranged and which are connected to at least one drive, by which they are rotated at different speeds in rotation.
- vibrators are used to bring objects such as profiles into the ground or to pull them out of the ground, or to compact soil material.
- the soil is stimulated by vibration and thus reaches a "pseudo-liquid state".
- By static load the pile can then be pressed into the ground.
- the vibration is characterized by a linear movement and is generated by pairwise counter-rotating imbalances.
- the vibration generators are linear vibration exciters whose centrifugal force is generated by rotating imbalances. Move these vibrators with variable speed.
- the size of the unbalance is also called a static moment.
- the course of the velocity of the linear vibration exciter corresponds to a periodically recurring function, in particular a sine function. Due to the sinusoidal course of the force generated by means of the rotating unbalanced masses a temporally offset alternately acting in and against the direction of advance drive is generated. This is ultimately determined by static forces, in particular dead weight and static loads. Without the superposition of the vibration with static forces, the pile would not move forward, but merely swing back and forth.
- a disadvantage of the known systems that the piling process with the aforementioned sinusoidal force curve has a considerable energy consumption, which is additionally increased by friction of the pile in the ground. The energy used for the vibrator causes virtually no propulsion.
- the invention aims to remedy this situation.
- the invention is based on the object to provide a vibration generator, which allows a directed force in the direction of advance. According to the invention, this object is solved by the features of the characterizing part of patent claim 1.
- a vibration generator which allows a directed force in the direction of advance.
- a directional characteristic in the direction of advance is generated by superposition of the sinusoidal force characteristics generated by the rotating imbalances.
- the direction of advance there is a much greater maximum force compared to the opposite direction. Since during the ramming process the ground can not follow the large acceleration in the direction of ramming, the pile rips off the resonating ground with each forward momentum impulse. Due to this periodic decoupling of soil and pile material less energy is supplied to the ground. As a result, the vibration load of the environment is also significantly reduced.
- the static moment of the first wave group is eight times as large as the static moment of the second wave group. As a result, a pronounced force peak is effected in the advancing direction.
- the present object is further achieved by the features of claim 3.
- the wave groups having a speed ratio of 1: 2: 3 and the ratio of the static moments of the wave groups to each other being substantially 100: 16.64: 3.68 the maximum acting force is increased by a further pronounced force peak in the direction of advance. This results in a further increase in energy efficiency, combined with an acceleration of the piling process causes.
- means for adjusting the effective direction of the vibrator are provided. This allows adaptation of the vibrator to different process requirements such as ramming and pulling.
- the means for adjusting the direction of action comprise a swivel motor, via which the phase position of at least two imbalance groups rotating at different rotational speeds is variable relative to one another.
- the at least two imbalance groups are connected via gears with the pivot motor, wherein at least one imbalance group with the stator and at least one imbalance group is connected to the rotor of the swing motor.
- the swing motor is a rotary-wing pivoting motor with a wing. This is distinguished from the 180-degree adjustable swivel motors by multiple higher torque and lower friction.
- the swing motor may also be a swivel motor with coarse thread.
- the vibration generator chosen as the embodiment are designed as vibrator gear.
- Such vibrators essentially consist of a housing in which gears provided with gears are rotatably mounted.
- the gears are each provided with imbalance masses.
- Such Vibratorgetriebe with rotatably mounted imbalance masses are the expert, for example from the DE 20 2007 006 283 U1 known.
- the following explanation of the embodiments is essentially limited to the arrangement of waves and imbalance masses.
- the shafts 11, 12 of the shaft group 1 are provided with toothed wheels 112, 122, on which imbalance masses 111, 121 are arranged.
- the imbalance masses 111, 121 are executed in the same embodiment.
- the shafts 21, 22 of the shaft group 2 are as it were provided with gears 212, 222, on which similar imbalance masses 211, 221 are arranged.
- the gears 112, 122, 212, 222 are designed such that upon rotation, the rotational speed of the shafts 21, 22 of the shaft group 2 is twice as large as the rotational speed of the shafts 11, 12.
- the imbalance masses 111, 121, 211, 221 are arranged such that the static moment of the wave group 1 is eight times as large as the static moment of the wave group. 2
- a pivot motor 5 is arranged, whose stator has a gear 51 and whose rotor has a gear 52.
- the wave groups 1, 2 are connected to each other via the swing motor 5 such that the gear 112 of the shaft 11 is engaged with the gear 52 of the swing motor 5; the gears 212, 222 of the shaft group 2 are connected to the gear 51 of the swing motor 5 in engagement.
- the swivel motor 5 is a rotary-wing pivoting motor with a wing.
- the wave groups 1, 2 of three shafts 11, 12, 13, 21, 22, 23 are formed, which are each provided with imbalance masses 111, 121, 131, 211, 221, 231.
- the imbalance masses 111, 121 and 131 form the imbalance group 101
- the imbalance masses 211, 221 and 232 form the imbalance group 201.
- the gears 112, 122, 132, 212, 222, 232 of the shafts 11, 12, 13, 21, 22, 23 are again chosen such that during rotation, the waves of the wave group 2 have twice the speed, as the waves of the wave group 1.
- the number of waves of the wave groups 1, 2 can also be chosen differently.
- an additional shaft 24 is added with corresponding imbalance mass 241.
- a compact design can be achieved (see. FIG. 4c) ).
- a pivot motor 5 is arranged between the shafts 11, 12, 13 of the shaft group 1 and the shafts 21, 22, 23 of the shaft group 2, a pivot motor 5 is arranged.
- the unbalanced masses 111, 121 and 131 form the imbalance group 101
- the imbalance masses 211, 221 and 232 form the imbalance group 201.
- the gears 112, 122, 132 of the shaft group 1 with the gear 51 of the stator of the swing motor 5 are engaged and the gears 212, 222, 232 of the shaft group 2 are engaged with the gear 52 of the rotor of the swing motor 5.
- the pivot motor 5 is a rotary wing pivot motor with three wings.
- FIG. 6 is a modified structure of the aforementioned arrangement according to FIG. 5 shown, which allows a significant reduction in length, but in which instead of six waves eight waves are required, but this is reflected in a lower load on the shaft bearings and advantages in terms of recoverable centrifugal force, suitability for high speeds and lower sensitivity large angular acceleration brings with it.
- an additional speed stage whose unbalance rotate at three times speed can be used.
- FIG. 7 is such an arrangement based on the transmission concept according to FIG. 5 shown. This falls slightly wider, since the lower large gear 132, which drives the two juxtaposed shafts 31, 32, is shifted relative to the transmission center.

Abstract
Description
Die Erfindung betrifft einen Schwingungserzeuger, umfassend zwei, drei oder vier Wellengruppen, auf denen mindestens zwei Unwuchtgruppen angeordnet sind und die mit wenigstens einem Antrieb verbunden sind, durch den sie mit unterschiedlichen Drehzahlen in Rotation versetzt werden.The invention relates to a vibration generator, comprising two, three or four wave groups, on which at least two imbalance groups are arranged and which are connected to at least one drive, by which they are rotated at different speeds in rotation.
Im Bauwesen werden Schwingungserzeuger verwendet, um Objekte, wie beispielsweise Profile, in den Boden einzubringen oder aus dem Boden zu ziehen oder auch um Bodenmaterial zu verdichten. Der Boden wird durch Vibration angeregt und erreicht so einen "pseudoflüssigen Zustand". Durch statische Auflast kann das Rammgut dann in den Baugrund gedrückt werden. Die Vibration ist gekennzeichnet durch eine lineare Bewegung und wird durch paarweise gegenläufig rotierende Unwuchten generiert.In construction, vibrators are used to bring objects such as profiles into the ground or to pull them out of the ground, or to compact soil material. The soil is stimulated by vibration and thus reaches a "pseudo-liquid state". By static load the pile can then be pressed into the ground. The vibration is characterized by a linear movement and is generated by pairwise counter-rotating imbalances.
Die Schwingungserzeuger sind linear wirkende Schwingungserreger, deren Fliehkraft durch rotierende Unwuchten generiert wird. Diese Schwingungserreger bewegen sich mit veränderlicher Geschwindigkeit. Die Größe der Unwucht wird auch als statisches Moment benannt. Der Verlauf der Geschwindigkeit des linearen Schwingungserregers entspricht einer periodisch wiederkehrenden Funktion, insbesondere einer Sinusfunktion. Auf Grund des sinusförmigen Verlaufs der mittels der rotierenden Unwuchtmassen erzeugten Kraftwirkung wird eine zeitlich versetzt abwechselnd in und entgegen der Vortriebsrichtung wirkender Antrieb erzeugt. Diese wird letztlich durch statische Kräfte, insbesondere Eigengewicht und statische Auflasten bestimmt. Ohne die Überlagerung der Schwingung mit statischen Kräften würde sich das Rammgut nicht vorwärts bewegen, sondern lediglich vor-und zurückschwingen. Nachteilig an den vorbekannten Systemen ist, dass der Rammvorgang mit dem vorgenannten sinusförmigen Kraftverlauf einen erheblichen Energieverbrauch aufweist, der durch Reibung des Rammguts im Boden zusätzlich vergrößert ist. Die für den Schwingungserzeuger aufgewandte Energie bewirkt praktisch keinen Vortrieb.The vibration generators are linear vibration exciters whose centrifugal force is generated by rotating imbalances. Move these vibrators with variable speed. The size of the unbalance is also called a static moment. The course of the velocity of the linear vibration exciter corresponds to a periodically recurring function, in particular a sine function. Due to the sinusoidal course of the force generated by means of the rotating unbalanced masses a temporally offset alternately acting in and against the direction of advance drive is generated. This is ultimately determined by static forces, in particular dead weight and static loads. Without the superposition of the vibration with static forces, the pile would not move forward, but merely swing back and forth. A disadvantage of the known systems that the piling process with the aforementioned sinusoidal force curve has a considerable energy consumption, which is additionally increased by friction of the pile in the ground. The energy used for the vibrator causes virtually no propulsion.
Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zu Grunde, einen Schwingungserzeuger zu schaffen, der eine gerichtete Kraftwirkung in Vortriebsrichtung ermöglicht. Gemäß der Erfindung wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gelöst.The invention aims to remedy this situation. The invention is based on the object to provide a vibration generator, which allows a directed force in the direction of advance. According to the invention, this object is solved by the features of the characterizing part of
Mit der Erfindung ist ein Schwingungserzeuger geschaffen, der eine gerichtete Kraftwirkung in Vortriebsrichtung ermöglicht. Durch die Kopplung wenigstens zweier Wellengruppen mit einem Drehzahlverhältnis von 2 : 1 und einem Verhältnis des statischen Moments von zwischen 6 : 1 und 10 : 1 wird durch Überlagerung der durch die rotierenden Unwuchten erzeugten sinusförmigen Kraftkennlinien eine gerichtete Kennlinie in Vortriebsrichtung erzeugt. In Vortriebsrichtung ergibt sich eine wesentlich größere Maximalkraft im Vergleich zur entgegengesetzten Richtung. Da beim Rammprozess der Boden der großen Beschleunigung in Rammrichtung nicht folgen kann, reißt das Rammgut bei jedem Vortriebsimpuls vom mitschwingenden Boden ab. Auf Grund dieser periodischen Entkopplung von Boden und Rammgut wird dem Baugrund weniger Energie zugeführt. Hierdurch wird weiterhin auch die Vibrationsbelastung der Umgebung deutlich reduziert. Bevorzugt ist das statische Moment der ersten Wellengruppe acht Mal so groß wie das statische Moment der zweiten Wellengruppe. Hierdurch ist eine ausgeprägte Kraftspitze in Vortriebsrichtung bewirkt.With the invention, a vibration generator is provided which allows a directed force in the direction of advance. By coupling at least two wave groups with a speed ratio of 2: 1 and a ratio of the static torque of between 6: 1 and 10: 1, a directional characteristic in the direction of advance is generated by superposition of the sinusoidal force characteristics generated by the rotating imbalances. In the direction of advance, there is a much greater maximum force compared to the opposite direction. Since during the ramming process the ground can not follow the large acceleration in the direction of ramming, the pile rips off the resonating ground with each forward momentum impulse. Due to this periodic decoupling of soil and pile material less energy is supplied to the ground. As a result, the vibration load of the environment is also significantly reduced. Preferably, the static moment of the first wave group is eight times as large as the static moment of the second wave group. As a result, a pronounced force peak is effected in the advancing direction.
Die vorliegende Aufgabe wird weiterhin durch die Merkmale des Patentanspruchs 3 gelöst. Durch den Einsatz von drei Wellengruppen, auf denen mindestens drei Unwuchtgruppen angeordnet sind, wobei die Wellengruppen ein Drehzahlverhältnis von 1 : 2 : 3 aufweisen und das Verhältnis der statischen Momente der Wellengruppen zueinander im Wesentlichen 100 : 16,64 : 3,68 beträgt, wird die maximal wirkende Kraft durch eine weiter ausgeprägte Kraftspitze in Vortriebsrichtung erhöht. Hierdurch ist eine weitere Steigerung der Energieeffizienz, verbunden mit einer Beschleunigung des Rammprozesses, bewirkt.The present object is further achieved by the features of
Die gestellte Aufgabe wird weiterhin durch die Merkmale des Patentanspruchs 4 gelöst. Durch den Einsatz von vier Wellengruppen, auf denen mindestens vier Unwuchtgruppen angeordnet sind, wobei das Drehzahlverhältnis der Wellengruppen zueinander im Wesentlichen 1 : 2 : 3 : 4 beträgt und das Verhältnis der statischen Momente der Wellengruppen zueinander im Wesentlichen 100 : 18,72 : 5,6 : 1,38 beträgt, ist eine weitere Ausprägung des Kraftverlaufs in Vortriebsrichtung erzielt.The stated object is further achieved by the features of claim 4. By using four wave groups on which at least four imbalance groups are arranged, wherein the speed ratio of the wave groups to one another is essentially 1: 2: 3: 4 and the ratio of the static moments of the wave groups to one another is substantially 100: 18.72: 5, 6: 1.38, a further expression of the force curve is achieved in the advancing direction.
In Weiterbildung der Erfindung sind Mittel zur Verstellung der Wirkrichtung des Schwingungserzeugers vorgesehen. Hierdurch ist eine Anpassung des Schwingungserzeugers an unterschiedliche Prozessanforderungen wie beispielsweise Rammen und Ziehen ermöglicht.In a further development of the invention means for adjusting the effective direction of the vibrator are provided. This allows adaptation of the vibrator to different process requirements such as ramming and pulling.
In Ausgestaltung der Erfindung umfassen die Mittel zur Verstellung der Wirkrichtung einen Schwenkmotor, über den die Phasenlage wenigstens zweier mit unterschiedlicher Drehzahl rotierender Unwuchtgruppen zueinander veränderbar ist. Hierdurch ist eine Umstellung der Wirkrichtung ohne erforderliche Umbaumaßnahmen ermöglicht.In an embodiment of the invention, the means for adjusting the direction of action comprise a swivel motor, via which the phase position of at least two imbalance groups rotating at different rotational speeds is variable relative to one another. As a result, a conversion of the effective direction is made possible without any necessary conversion measures.
In weiterer Ausgestaltung der Erfindung sind die wenigstens zwei Unwuchtgruppen über Zahnräder mit dem Schwenkmotor verbunden, wobei wenigstens eine Unwuchtgruppe mit dem Stator und wenigstens eine Unwuchtgruppe mit dem Rotor des Schwenkmotors verbunden ist. Hierdurch ist eine direkte Verstellung der Unwuchtgruppen über den Schwenkmotor ermöglicht.In a further embodiment of the invention, the at least two imbalance groups are connected via gears with the pivot motor, wherein at least one imbalance group with the stator and at least one imbalance group is connected to the rotor of the swing motor. As a result, a direct adjustment of the imbalance groups on the swing motor allows.
Vorteilhaft ist der Schwenkmotor ein Drehflügelschwenkmotor mit einem Flügel. Dieser zeichnet sich gegenüber den 180 Grad verstellbaren Schwenkmotoren durch mehrfach höheres Drehmoment und geringere Reibung aus. Alternativ kann der Schwenkmotor auch ein Schwenkmotor mit Steilgewinde sein.Advantageously, the swing motor is a rotary-wing pivoting motor with a wing. This is distinguished from the 180-degree adjustable swivel motors by multiple higher torque and lower friction. Alternatively, the swing motor may also be a swivel motor with coarse thread.
