Description
Die Erfindung betrifft eine Bodenverdichtungsvorrichtung gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a soil compaction device according to the preamble of claim 1.
Derartige Bodenverdichtungsvorrichtungen, z. B. eine Vibrationsplatte mit der Typenbezeichnung "Wacker DPU 7060", sind bekannt und haben sich in der Praxis, insbesondere zur Verdichtung von überwiegend grobkörnigen oder schwachbindigen Böden, hervorragend bewährt. Dabei ist auf einer Bodenkontaktplatte ein von einem Motor angetriebener Schwingungserreger angebracht. der die Bodenkontaktplatte in eine Vertikalschwingung versetzt, die dann auf den Boden übertragen wird. Die erzeugte Schwingung weist üblicherweise eine konstante oder auch veränderbare horizontale Kraftkomponente auf. die für eine Vorwärts-. Rückwärts- oder Lenkbewegung der Vibrationsplatte sorgt. Die Horizontalbewegung der Vibrationsplatte wird dabei vom Bediener über eine Führungsdeichsel oder einen Führungsbügel unterstützt. An der Führungsdeichsel kann ein mit Hydraulikventilen gekoppelter Bedienhebel vorgesehen sein, mit dem sich durch eine Stellhydraulik die Bewegungsrichtung der Vibrationsplatte einstellen läßt. Weiterhin ist es bekannt, die Lenk- und Richtungsfunktionen über eine Fernsteuerung durchzuführen. Gerade bei ferngesteuerten Platten erfolgt die Lenkung im Regelfall dadurch, daß der Schwingungserreger geteilte Unwuchten aufweist, die im Lenkfall gegeneinander arbeitend eingestellt werden und eine Kreis- bzw. Gierbewegung der Maschine bewirken.Such soil compaction devices, e.g. B. a vibration plate with the Type designation "Wacker DPU 7060" are known and have been used in the Practice, especially for the compression of predominantly coarse or weak cohesive soils, tried and tested. It is on a ground contact plate a vibration exciter driven by a motor is attached. which sets the ground contact plate in a vertical vibration, the then transferred to the floor. The generated vibration usually shows a constant or changeable horizontal force component. those for a forward. Backward or steering movement of the vibration plate provides. The horizontal movement of the vibrating plate is controlled by the operator supported via a guide drawbar or a guide bracket. At the A control lever coupled with hydraulic valves can be provided for the guide drawbar with which the direction of movement can be determined by means of a control hydraulics the vibration plate can be adjusted. Furthermore, it is known the steering and To perform directional functions via a remote control. Especially with remote controlled Plates are usually controlled by the fact that the Vibration exciter has divided unbalances, which are against each other when steering be set working and a circular or yawing movement of the machine cause.
Auch bei ferngesteuerten Vibrationsplatten kann der Bediener jederzeit manuell in den Bewegungs- bzw. Lenkvorgang eingreifen, indem er an dem Führungsbügel zieht. Der Bediener muß dazu gleichzeitig Knöpfe an der Fernsteuerung drücken und am Führungsbügel zerren. Dies erfordert jedoch hohe Kräfte. da der Führungsbügel von ferngesteuerten Maschinen gegenüber den Führungsdeichseln von nicht ferngesteuerten Maschinen stark verkürzt ist. Da der Bediener gleichzeitig noch Bedienelemente der Steuerung wie Steuerknüppel, Druckknöpfe o. ä. betätigen muß, kann er den Führungsbügel nur mit einer Hand halten. Diese Art der Bedienung ist für den Bediener sehr anstrengend und daher dem Arbeitsfortschritt nicht zuträglich. Even with remote-controlled vibratory plates, the operator can manually at any time intervene in the movement or steering process by pressing on the guide bracket draws. The operator must simultaneously have buttons on the remote control press and pull on the guide bracket. However, this requires high forces. because the guide bracket of remote-controlled machines opposite the guide drawbar is greatly shortened by machines that are not remotely controlled. Since the Operator at the same time control elements of the control such as joysticks, Must press push buttons or the like, he can only use the guide bracket Hold hands. This type of operation is very tiring for the operator and therefore not conducive to work progress.
Der Erfindung liegt die Aufgabe zugrunde, eine Bodenverdichtungsvorrichtung anzugeben, die auch bei Vorhandensein einer Fernsteuerung oder Druckknöpfen an einem Bedienungspult durch den Bediener leicht manuell lenkbar ist.The invention has for its object a soil compaction device specify that even in the presence of a remote control or push buttons can be easily manually steered by the operator on a control panel.
Die Aufgabe wird erfindungsgemäß durch eine Bodenverdichtungsvorrichtung mit den Merkmalen von Patentanspruch 1 gelöst. Vorteilhafte Weiterentwicklungen der Erfindung sind den abhängigen Ansprüchen zu entnehmen.The object is achieved by a soil compaction device solved with the features of claim 1. Advantageous further developments the invention can be found in the dependent claims.
Die Erfindung ist dadurch gekennzeichnet, daß eine Sensoreinrichtung zum Ermitteln der Stellung von wenigstens einem Bedienelement vorgesehen ist, durch die ein Signal zum Ansteuern einer Stelleinrichtung für den Schwingungserreger erzeugbar ist. Dies ermöglicht es, daß der Bediener über das Bedienelement die Stelleinrichtung betätigen kann, ohne daß - wie beim Stand der Technik - zusätzliche kostenintensive und wartungsaufwendige Hydraulikventile am Bedienelement vorgesehen sein müssen.The invention is characterized in that a sensor device for Determining the position of at least one control element is provided, through which a signal to control an actuator for the Vibration exciter can be generated. This allows the operator to the control element can operate the adjusting device without - as with State of the art - additional cost-intensive and maintenance-intensive Hydraulic valves must be provided on the control element.
Bei einer besondes vorteilhaften Weiterentwicklung der Erfindung sind das Bedienelement und die Sensoreinrichtung an einem Führungsbügel der Bodenverdichtungsvorrichtung angebracht. Betätigt der Bediener nun ohne großen Kraftaufwand das bewegliche Bedienelement und verlagert es somit aus einer Ausgangsstellung, wird die Stellungsänderung von der Sensoreinrichtung erfaßt und ein entsprechendes Signal an die Stelleinrichtung abgegeben. Die Stelleinrichtung verändert in an sich bekannter Weise die Stellung bzw. Phasenlage der rotierenden Unwuchtmassen zueinander, wodurch sich die Horizontalkomponente einer resultierenden Gesamtkraft ändert und ein geändertes Richtungsverhalten der Vibrationsplatte erzeugt wird.In a particularly advantageous further development of the invention, these are Control element and the sensor device on a guide bracket of the soil compaction device appropriate. The operator now operates without much Exertion of force the movable control element and thus relocated it from one Starting position, the change in position is detected by the sensor device and emitted a corresponding signal to the actuating device. The Actuating device changes the position or phase position in a manner known per se of the rotating unbalanced masses to each other, causing the horizontal component a resulting total force changes and a changed one Directional behavior of the vibration plate is generated.
Als Bedienelemente eignen sich - je nach Ausstattung der Vibrationsplatte - ein oder zwei Handbügel, die zusammen oder getrennt voneinander bewegbar sind. Weiterhin kann das Bedienelement auch in Form eines "Joy Sticks" ausgeführt sein.Suitable controls are - depending on the equipment of the vibration plate - a or two handbands that can be moved together or separately. Furthermore, the control element can also be designed in the form of a "joy stick" his.
Besonders vorteilhaft wird die Erfindung bei Vibrationsplatten mit Fernsteuerung eingesetzt, bei der - wenn überhaupt - an dem Gerät selbst lediglich Druckknöpfe zum direkten Beaufschlagen von Hydraulikventilen der hydraulischen Stelleinrichtung sowie ein nur kurzer Führungsbügel vorgesehen sind. Die Bereitstellung eines zusätzlichen beweglichen Bedienelements mit Sensoreinrichtung gewährleistet, daß der Bediener die Vibrationsplatte wie eine Vibrationsplatte ohne Fernsteuerung bequem führen kann.The invention is particularly advantageous in the case of vibration plates with remote control used, if at all, only on the device itself Push buttons for direct actuation of hydraulic valves of the hydraulic Actuator and only a short guide bracket are provided. The provision of an additional movable control element with Sensor device ensures that the operator like the vibration plate a vibrating plate can be conveniently guided without remote control.

Die Wellen 1, 2 sowie die Unwuchtmassen 3. 4 können jeweils in axialer
Richtung geteilt sein, um - bei entsprechender Phasenlage - ein Giermoment zu
erzeugen, das die Vibrationsplatte auf der Stelle kreisen oder - bei gleichzeitiger
Vorwärtsbewegung - einen Kurvenradius fahren läßt.The
Die Veränderung der Phasenlagen der Wellen 1 und 2 zueinander sowie der
Phasenlagen von zwei auf einer Welle angeordneten Unwuchtmassen erfolgt
über eine an sich bekannte Stelleinrichtung, bei der geeignete nicht dargestellte

Vibrationsplatte vorgesehen, die Funk- oder Infrarotsignale von einer nicht
dargestellten Sendeeinheit empfängt. Üblich ist auch der Empfang von elektrischen
Signalen über eine Kabel-Fernsteuerung. Die Signale werden in der
Empfangseinheit 9 gewandelt und beaufschlagen über eine Hydrauliksteuerung
10 in der Hydraulik 6 vorgesehene elektromagnetische Ventile.In the case of a remotely controllable vibration plate, a
Vor allem bei derartigen fernsteuerbaren Vibrationsplatten ist die Führungsdeichsel
7 nur als kurzer Führungsbügel ausgeführt. An der Vibrationsplatte
selbst sind darübcr hinaus oftmals keine zusätzlichen Bedienelemente vorgesehen,
da die Bedienung ausschließlich über die Sendeeinheit erfolgen soll.
Bei Kabelfernsteuerungen sind jedoch Vibrationsplatten bekannt, bei denen die
Sendeeinheit in eine entsprechende Aufnahme der Vibrationsplatte eingesetzt
werden kann und dann als Bedienpult dient.Especially with such remotely controllable vibratory plates is the
Bei einer manuellen Korrektur der Bewegung der Vibrationsplatte muß der Bediener mit einer Hand an dem kurzen Führungsbügel zerren und gleichzeitig mit der anderen Hand die Fernbedienung bzw. geeignete Druckknöpfe am Bedienungspult betätigen, um die gewünschte Bewegung der Vibrationsplatte zu erreichen.With a manual correction of the movement of the vibrating plate, the Pull operator with one hand on the short guide bracket and at the same time with the other hand the remote control or suitable push buttons on Operate the control panel to make the desired movement of the vibration plate to reach.

der Stellung eines Hydraulikventils bewirkt, sondern über eine ebenfalls am
Ende des Führungsbügels 7 angeordnete Sensoreinrichtung 11 erfaßt wird.In order to make this work easier for the operator, the invention also relates to

11 eignen sich grundsätzlich kapazitive, induktive und resistive
Sensoren, die in der Nähe des Steuerbügels 8 anzuordnen sind.The
In der Hydrauliksteuerung 10 wird das Signal elektromechanisch gewandelt, z.
