Definitions
- the invention relates firstly to a cable winch arrangement according to the preamble of claim 1, inter alia with a cable winch, a winch drive and a control device, and secondly to a method for operating a cable winch arrangement according to the preamble of claim 8.
- winch arrangements are used in particular in special civil engineering.
- Such winches are used, for example, for lowering and lifting so-called pile boring tools, with which holes are drilled with a drilling depth of about 100 m and drill diameters of about 1 m to 3 m.
- pile drilling due to the large diameter of the drill, the total weight of the drill string and optionally an additional contact force is used as a load for the drilling tool.
- the DE 24 59 778 A discloses a drilling rig having a winch mechanism which includes a hydrostatic drive rotatable drum for a cable and a retrieval device for the cable.
- the Nachlassvoriques is formed among other things of a hydraulic device of the winch drive, wherein a current control valve may be provided on the hydraulic unit for setting a desired lowering speed during the reduction process.
- a pressure device is provided with which an operation with a selectable force can be performed. This pressure device has a further hydraulically driven winch.
- the US 2,455,917 discloses a drilling control system with which the speed or load of a drill can be maintained at a predetermined value.
- the system of US 2,455,917 has a Auflastkontroll issued and a speed control device, each actuate its own brake for a winch drum.
- the invention has for its object to provide a winch assembly and a method for their operation, with which a reliable Auflast tortureung is possible with a simple structure.
- a first operating mode for lifting and lowering and a second operating mode can be switched by the control device, in which a load on a winch is adjustable.
- a basic idea of the invention is that a controller with two operating modes is provided.
- the controller is configured with a first mode of operation designed for normal lifting and lowering operation. In this operation, a fast and efficient lifting and lowering can take place without expensive control, as is sufficient, for example, for pile boring.
- the control can also be switched over to a second operating mode in which a desired reduced load can be set via an input possibility of the control, the control device correspondingly controlling and monitoring the winch drive via corresponding control elements.
- the controller may also include a control of the winch drive.
- the inventive design of the winch assembly allows such use also for well drilling without, as in the prior art, two drives must be provided.
- the winch drive comprises a hydraulic motor which is connected via hydraulic lines to a pressure energy source.
- a hydraulic motor allows a high power transmission in a compact arrangement.
- controllable valves are provided, which can be controlled via the control device.
- a measurement of the load on the rope can be achieved in a reliable and simple manner according to the invention in that at least one pressure sensor is arranged in the hydraulic lines for measuring a hydraulic pressure, wherein the pressure transducer with the control device communicates.
- the pressure in the hydraulic line correlates with the load and can thus be used via a corresponding consideration of a correlation rule in the control device for determining and controlling the desired load on the drill.
- a hydraulically actuated holding brake is formed, which is controllable via the control device.
- a first operating mode is set for lifting and lowering in the control device and that a second operating mode is set in which a load on a cable of the Winch is set.
- the cable winch assembly comprises a drum-shaped winch 22, which is rotatably mounted in a holder 23 and driven by a drive shaft 24 schematically represented by a winch drive 24.
- the winch 22 is detected by a holding brake 25, which acts on the drive shaft.
- Trained as a single hydraulic motor winch drive 24 is connected via a hydraulic line assembly explained in more detail below with at least one pressure energy source 20, which is a hydraulic pump.
- the hydraulic line arrangement comprises a multiplicity of valves which can be actuated via a control device 21 for setting the two operating modes explained below.
- This first mode of operation is used, for example, for the usual method in dry rotary drilling.
- the control device 21 sets the valves as follows: Valve 19 is depressurized; with valve 13, port A is blocked. Thus, there is no pressure on the valves 17 and 16 (and thus on 2).
- the proportional flow control valve 9, 10 is also closed in this mode of operation.
- the valve 14 is switched to high pressure.
- the trained as constant pump pressure energy source 20 thus promotes the flow directly through the valve 19 in a tank, not shown.
- the check valve 11 prevents as a second level of security next to the valve 17, that oil via the line B 'flows from the winch control 26.
- the load control is thus not active, but only the normal winch mode.
- the pressure energy can be provided by a further, not shown, pressure energy source.
- valve 2 If pressure is now given to "lifting” or “lowering”, the valve 2 is actuated via the shuttle valve in the winch control block 26 and via the shuttle valve 16 and thus the holding brake 25 is opened. Likewise, the brake valve opens in the winch control block 26 - but only just so far that the winch drive 24, the winch 22 controlled up or can unwind.
- This mode of operation is used, for example, when the drill is operated with a scavenging equipment such as well drilling.
- valve 19 is switched so that the pressure energy source 20 can generate high pressure.
- the valve 14 is switched to low pressure. This pressure setting is higher than the feed pressure, so that via the valve 14 no oil can flow out of the feed circuit.
- Valve 9, 10 is closed.
- the valve 13 can now be switched to unlock the check valve 17 and the Holding brake 25 with the help of valve 2 to open. The switching of valve 13 is only released when the pressure switch 12 indicates high enough pressure.
- valve 9 10 the control slowly opens valve 9, 10, so that the volume flow can flow off. If more volumetric flow flows out than is pumped by the pump 20, the winch 22 begins to unwind. In this operating mode, it is therefore possible to unwind the cable from the winch 22 with a predetermined load with the same winch drive 24, which can also be used in a normal winch operation.
- the control unit can close the flow control valve 9, 10 slightly as the pressure drops and thus to a high load, in order to reach the predetermined load again.
- the flow control valve 9, 10 is opened by the control device 21 accordingly.
- the drill string according to the invention will no longer be lowered as fast as the drilling progress or will even be lifted. If the determined ballast is too low, the drill string is lowered again faster by the winch 22 so that it is supported more strongly on the sole.

Description
Die Erfindung betrifft zum einen eine Seilwindenanordnung gemäß dem Oberbegriff des Anspruchs 1, unter anderem mit einer Seilwinde, einem Windenantrieb und einer Steuereinrichtung und zum anderen ein Verfahren zum Betrieb einer Seilwindenanordnung gemäß dem Oberbegriff des Anspruchs 8.The invention relates firstly to a cable winch arrangement according to the preamble of claim 1, inter alia with a cable winch, a winch drive and a control device, and secondly to a method for operating a cable winch arrangement according to the preamble of claim 8.
Derartige Seilwindenanordnungen werden insbesondere im Spezialtiefbau eingesetzt. Derartige Winden dienen beispielsweise zum Senken und Heben sogenannter Pfahlbohrwerkzeuge, mit welchen Bohrungen mit einer Bohrtiefe von ca. 100 m und Bohrdurchmessern von ca. 1 m bis 3 m abgeteuft werden. Beim Pfahlbohren wird aufgrund des großen Bohrdurchmessers das Gesamtgewicht des Bohrstranges und gegebenenfalls eine zusätzliche Anpresskraft als Auflast für das Bohrwerkzeug verwendet.Such winch arrangements are used in particular in special civil engineering. Such winches are used, for example, for lowering and lifting so-called pile boring tools, with which holes are drilled with a drilling depth of about 100 m and drill diameters of about 1 m to 3 m. In pile drilling, due to the large diameter of the drill, the total weight of the drill string and optionally an additional contact force is used as a load for the drilling tool.
Vom Pfahlbohren unterscheidet sich das sogenannte Brunnenbohren. Hierfür notwendige Brunnenbohrgeräte haben einen deutlich kleineren Bohrdurchmesser von etwa max. 300 mm bis 500 mm. Dafür müssen jedoch Bohrtiefen von mehreren 100 m bis etwa 1000 m erreichbar sein. Aufgrund des kleinen Bohrdurchmessers und der größeren Bohrtiefen wäre die durch das Eigengewicht des Bohrstranges erzeugte Auflast am Bohrkopf zu groß, so dass dieser geschädigt werden könnte. Um dies zu verhindern, muss die Auflast über die den Bohrstrang tragende Winde genau gesteuert reduziert werden. Eine solche Auflaststeuerweise wird üblicherweise mit speziellen Winden erreicht, welche zwei Antriebsmotore besitzen, wie es beispielsweise in der

Der Erfindung liegt die Aufgabe zugrunde, eine Seilwindenanordnung und ein Verfahren zu deren Betrieb anzugeben, mit welchen bei einem einfachen Aufbau eine zuverlässige Auflaststeuerung möglich ist.The invention has for its object to provide a winch assembly and a method for their operation, with which a reliable Auflaststeuerung is possible with a simple structure.
Die Aufgabe wird erfindungsgemäß durch eine Seilwindenanordnung mit den Merkmalen des Anspruchs 1 bzw. durch ein Verfahren zum Betrieb einer Seilwindenanordnung gemäß den Merkmalen des Anspruchs 8 gelöst. Bevorzugte Ausführungsform der Erfindung sind in den abhängigen Ansprüchen angegeben.The object is achieved by a winch assembly with the features of claim 1 and by a method for operating a cable winch assembly according to the features of claim 8. Preferred embodiments of the invention are indicated in the dependent claims.
Bei der erfindungsgemäßen Seilwindenanordnung ist vorgesehen, dass durch die Steuereinrichtung ein erster Betriebsmodus für ein Heben und Senken und ein zweiter Betriebsmodus einschaltbar ist, in welchem eine Auflast an einer Seilwinde einstellbar ist.In the cable winch arrangement according to the invention it is provided that a first operating mode for lifting and lowering and a second operating mode can be switched by the control device, in which a load on a winch is adjustable.
Ein Grundgedanke der Erfindung liegt darin, dass eine Steuerung mit zwei Betriebsarten vorgesehen ist. Die Steuerung ist mit einem ersten Betriebsmodus ausgebildet, der für einen normalen Hebe- und Senkbetrieb ausgelegt ist. In diesem Betrieb kann ohne eine aufwendige Steuerung ein schnelles und effizientes Heben und Senken erfolgen, wie es beispielsweise für das Pfahlbohren ausreichend ist. Die Steuerung ist aber erfindungsgemäß auch auf einen zweiten Betriebsmodus umschaltbar, in welchem über eine Eingabemöglichkeit der Steuerung eine gewünschte reduzierte Auflast einstellbar ist, wobei die Steuereinrichtung über entsprechende Steuerorgane den Windenantrieb entsprechend steuert und überwacht. Die Steuerung kann dabei auch eine Regelung des Windenantriebes beinhalten. Die erfindungsgemäße Ausgestaltung der Seilwindenanordnung erlaubt so einen Einsatz auch für das Brunnenbohren, ohne dass wie im Stand der Technik zwei Antriebe vorgesehen werden müssen.A basic idea of the invention is that a controller with two operating modes is provided. The controller is configured with a first mode of operation designed for normal lifting and lowering operation. In this operation, a fast and efficient lifting and lowering can take place without expensive control, as is sufficient, for example, for pile boring. However, according to the invention, the control can also be switched over to a second operating mode in which a desired reduced load can be set via an input possibility of the control, the control device correspondingly controlling and monitoring the winch drive via corresponding control elements. The controller may also include a control of the winch drive. The inventive design of the winch assembly allows such use also for well drilling without, as in the prior art, two drives must be provided.
Gemäß der Erfindung ist vorgesehen, dass der Windenantrieb einen Hydraulikmotor aufweist, der über Hydraulikleitungen mit einer Druckenergiequelle verbunden ist. Ein Hydraulikmotor erlaubt bei einer kompakten Anordnung eine hohe Kraftübertragung.According to the invention it is provided that the winch drive comprises a hydraulic motor which is connected via hydraulic lines to a pressure energy source. A hydraulic motor allows a high power transmission in a compact arrangement.
Eine besonders robuste und zuverlässige Steuerungsanordnung wird nach der Erfindung dadurch erreicht, dass steuerbare Ventile vorgesehen sind, welche über die Steuereinrichtung ansteuerbar sind.A particularly robust and reliable control arrangement is achieved according to the invention in that controllable valves are provided, which can be controlled via the control device.
Eine Messung der Auflast an dem Seil, wie es beispielsweise für ein Brunnenbohren erforderlich ist, kann in zuverlässiger und einfacher Weise nach der Erfindung dadurch erreicht werden, dass in den Hydraulikleitungen mindestens ein Druckaufnehmer zum Messen eines Hydraulikdruckes angeordnet ist, wobei der Druckaufnehmer mit der Steuereinrichtung in Verbindung steht. Gemäß einer Erkenntnis der Erfindung korreliert der Druck in der Hydraulikleitung mit der Auflast und kann so über eine entsprechende Berücksichtigung einer Korrelationsregel in der Steuereinrichtung zur Bestimmung und Steuerung bzw. Regelung der gewünschten Auflast am Bohrgerät verwendet werden.A measurement of the load on the rope, such as is required for a well drilling, can be achieved in a reliable and simple manner according to the invention in that at least one pressure sensor is arranged in the hydraulic lines for measuring a hydraulic pressure, wherein the pressure transducer with the control device communicates. According to a recognition of the invention, the pressure in the hydraulic line correlates with the load and can thus be used via a corresponding consideration of a correlation rule in the control device for determining and controlling the desired load on the drill.
Zur Erhöhung der Betriebssicherheit der erfindungsgemäßen Seilwindenanordnung ist es vorgesehen, dass an der Seilwinde eine hydraulisch betätigbare Haltebremse ausgebildet ist, welche über die Steuereinrichtung steuerbar ist.To increase the reliability of the winch assembly according to the invention, it is provided that on the winch a hydraulically actuated holding brake is formed, which is controllable via the control device.
Beim erfindungsgemäßen Verfahren.zum Betrieb einer Seilwindenanordnung ist vorgesehen, dass für ein Heben und Senken in der Steuereinrichtung ein erster Betriebsmodus eingestellt wird und dass ein zweiter Betriebsmodus eingestellt wird, in welchem eine Auflast an einem Seil der Winde eingestellt wird. Durch dieses Verfahren können die vorstehend genannten Vorteile beim Betrieb der erfindungsgemäßen Seilwindenanordnung erreicht werden.In the method according to the invention for operating a cable winch arrangement, it is provided that a first operating mode is set for lifting and lowering in the control device and that a second operating mode is set in which a load on a cable of the Winch is set. By this method, the above-mentioned advantages in the operation of the winch assembly according to the invention can be achieved.
Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispieles weiter erläutert, welches schematisch in dem beigefügten Hydraulikschaltplan dargestellt ist.The invention will be further explained with reference to a preferred embodiment, which is shown schematically in the accompanying hydraulic circuit diagram.
Die erfindungsgemäße Seilwindenanordnung umfasst eine trommelförmige Seilwinde 22, welche drehbar in einer Halterung 23 gelagert und über eine schematisch dargestellte Antriebswelle mittels eines Windenantriebes 24 antreibbar ist. Die Seilwinde 22 ist über eine Haltebremse 25 feststellbar, welche auf die Antriebswelle einwirkt. Der als einzelner Hydraulikmotor ausgebildete Windenantrieb 24 ist über eine nachfolgend näher erläuterte Hydraulikleitungsanordnung mit mindestens einer Druckenergiequelle 20 verbunden, welche eine hydraulische Pumpe ist.The cable winch assembly according to the invention comprises a drum-
Die Hydraulikleitungsanordnung umfasst eine Vielzahl von Ventilen, welche über eine Steuerungseinrichtung 21 zum Einstellen der beiden nachfolgend erläuterten Betriebsmodi ansteuerbar sind.The hydraulic line arrangement comprises a multiplicity of valves which can be actuated via a
Dieser erste Betriebsmodus wird beispielsweise für die bei Trockendrehbohrgeräten üblichen Verfahren verwendet.This first mode of operation is used, for example, for the usual method in dry rotary drilling.
Die Steuereinrichtung 21 stellt die Ventile folgendermaßen ein: Ventil 19 ist drucklos geschaltet; bei Ventil 13 ist Anschluss A gesperrt. Somit liegt kein Druck an den Ventilen 17 und 16 (und damit an 2) an. Das proportionale Stromregelventil 9, 10 ist in diesem Betriebsmodus ebenfalls geschlossen. Das Ventil 14 ist auf hohen Druck geschaltet.The
Die als Konstantpumpe ausgebildete Druckenergiequelle 20 fördert also den Volumenstrom direkt über das Ventil 19 in einen nicht dargestellten Tank. Das Rückschlagventil 11 verhindert als zweite Sicherheitsstufe neben dem Ventil 17, dass Öl über die Leitung B' aus der Windensteuerung 26 abfließt. Die Auflaststeuerung ist somit nicht aktiv, sondern nur der normale Windenmodus. Die Druckenergie kann hierfür durch eine weitere nicht dargestellte Druckenergiequelle bereitgestellt werden.The trained as constant pump
Wird nun Druck auf "Heben" oder "Senken" gegeben, wird über das Wechselventil im Windensteuerungsblock 26 und über das Wechselventil 16 das Ventil 2 betätigt und somit die Haltebremse 25 geöffnet. Ebenso öffnet das Bremsventil im Windensteuerungsblock 26 - aber nur gerade soweit, dass der Windenantrieb 24 die Seilwinde 22 kontrolliert auf- oder abspulen kann.If pressure is now given to "lifting" or "lowering", the
Dieser Betriebsmodus wird beispielsweise verwendet, wenn das Bohrgerät mit einer Spülbohrausrüstung, etwa zum Brunnenbohren, betrieben wird.This mode of operation is used, for example, when the drill is operated with a scavenging equipment such as well drilling.
Das Ventil 19 wird umgeschaltet, so dass die Druckenergiequelle 20 Hochdruck erzeugen kann. Das Ventil 14 wird auf niedrigen Druck umgeschaltet. Diese Druckeinstellung ist höher als der Einspeisedruck, so dass über das Ventil 14 kein Öl aus dem Einspeisekreis abfließen kann. Ventil 9, 10 ist geschlossen. Das Ventil 13 kann nun umgeschaltet werden, um das Rückschlagventil 17 zu entsperren und die Haltebremse 25 mit Hilfe von Ventil 2 zu öffnen. Die Umschaltung von Ventil 13 wird nur freigegeben, wenn der Druckschalter 12 genügend hohen Druck anzeigt.The
Nach Öffnen der Haltebremse 25 spult die Seilwinde 22 mit niedriger Geschwindigkeit auf, da die Druckenergiequelle 20 Volumenstrom liefert. Mit dem Druckaufnehmer 8 kann nun der zum Heben des freischwebenden Spülbohrstrangs notwendige Druck erfasst werden. Zum Errechnen der Last an der Winde (entspricht in diesem Zustand dem Eigengewicht des Bohrstrangs) anhand des Drucks muss die vom Ventil 14 erzeugte Vorspannung berücksichtigt werden.After opening the
Nun öffnet die Steuerung langsam Ventil 9, 10, so dass der Volumenstrom abfließen kann. Fließt mehr Volumenstrom ab, als von der Pumpe 20 gefördert wird, beginnt die Seilwinde 22 abzuspulen. Es ist in diesem Betriebsmodus also ein Abspulen des Seiles von der Seilwinde 22 mit einer vorgegebenen Auflast mit demselben Windenantrieb 24 möglich, der auch in einem normalen Windenbetrieb eingesetzt werden kann.Now the control slowly opens valve 9, 10, so that the volume flow can flow off. If more volumetric flow flows out than is pumped by the
Wenn sich der Bohrstrang auf die Sohle absenkt, steigt die Auflast auf den Bohrkopf. Die Steuerung achtet nun darauf, dass die eingestellte Auflast nicht überschritten wird.As the drill string descends to the sole, the load on the bit increases. The controller now ensures that the set load is not exceeded.
Durch die kontinuierliche Druckmessung am Aufnehmer 8 kann die Steuerung bei fallendem Druck und damit zu großer Auflast das Stromregelventil 9, 10 etwas schließen, um die vorgegebene Auflast wieder zu erreichen. Bei steigendem Druck am Druckaufnehmer 8 und damit zu geringer Auflast wird das Stromregelventil 9, 10 durch die Steuerungseinrichtung 21 entsprechend geöffnet.As a result of the continuous pressure measurement on the sensor 8, the control unit can close the flow control valve 9, 10 slightly as the pressure drops and thus to a high load, in order to reach the predetermined load again. With increasing pressure at the pressure transducer 8 and thus to a low load, the flow control valve 9, 10 is opened by the
Ist die Auflast also zu groß, wird durch die erfindungsgemäße Steuerung der Bohrstrang nicht mehr so schnell abgesenkt, wie der Bohrfortschritt ist, oder wird sogar angehoben. Ist die ermittelte Auflast zu niedrig, wird der Bohrstrang durch die Seilwinde 22 wieder schneller abgesenkt, so dass sich dieser stärker auf der Sohle abstützt.If the ballast is therefore too large, the drill string according to the invention will no longer be lowered as fast as the drilling progress or will even be lifted. If the determined ballast is too low, the drill string is lowered again faster by the
Nach Beendigung des Abbohrens wird zum Ziehen des Bohrstranges wieder in den ersten Betriebsmodus umgeschaltet.After completion of the drilling is switched to pull the drill string back to the first operating mode.
