Abstract

A driving mechanism for a cable-handling winch (22) is tuned to a driving mechanism of a cable-pulling machine (20) with a linear driving mechanism and controlled in such a way that it is only activated during the working stroke of the cable-pulling machine so as to wind up a length of cable corresponding to the working stroke of the cable-pulling machine.

Description

Die Erfindung betrifft eine Seilzugvorrichtung zur Verwendung beim Verlegen oder Erneuern von Leitungen im Boden, umfassend eine Seilzugmaschine und eine dieser nachgeschaltete Seilwinde.The invention relates to a cable pulling device for use in laying or renewing cables in the ground, comprising a cable pulling machine and one of these downstream winch.

Eine Seilzugvorrichtung der vorstehend genannten Art ist beispielsweise aus der DE 103 02 194 B3 bekannt. Bei der dort beschriebenen Lösung hat die Seilwinde einen zuggeregelten Schalter für das Zuschalten der von einem Linearantrieb gebildeten Seilzugmaschine. Bei relativ geringen Zugkräften wird das Seil alleine von der Seilwinde gezogen. Muss ein hoher Widerstand durch entsprechend größere Zugkräfte überwunden werden, wird über den auf Zug ansprechenden Schalter automatisch der Linearantrieb zugeschaltet. Auch wenn somit die maximalen Zugkräfte von dem Linearantrieb aufgebracht werden, muss die Seilwinde einen relativ starken Antrieb haben, um die normalen Zugkräfte aufbringen zu können.A cable pulling device of the aforementioned type is for example from the DE 103 02 194 B3 known. In the solution described there, the winch has a tensioned switch for the connection of the cable tractor formed by a linear drive. At relatively low tensile forces, the rope is pulled by the winch alone. If a high resistance must be overcome by correspondingly greater tensile forces, the linear drive is automatically switched on via the train-responsive switch. Thus, even if the maximum tensile forces are applied by the linear drive, the winch must have a relatively strong drive to apply the normal tensile forces can.

Der Erfindung liegt die Aufgabe zugrunde, eine Seilzugvorrichtung der eingangs genannten Art anzugeben, die kostengünstig herzustellen und einfach und flexibel in der Handhabung ist.The invention has for its object to provide a cable pulling device of the type mentioned, which is inexpensive to manufacture and easy and flexible to use.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Antrieb der Seilwinde in Übereinstimmung mit dem Antrieb der Seilzugmaschine derart gesteuert ist, dass er nur während des Arbeitshubes der Seilzugmaschine aktiviert ist, um die dem Arbeitshub der Seilzugmaschine entsprechende Seillänge aufzuwickeln.This object is achieved in that the drive of the winch is controlled in accordance with the drive of the cable pulling machine so that it is activated only during the working stroke of the cable machine to wind the working stroke of the cable pulley corresponding pitch.

Bei der erfindungsgemäßen Seilzugvorrichtung werden die für den Arbeitshub benötigten Zugkräfte allein von der Seilzugmaschine aufgebracht. Die Seilwinde übernimmt nur die Seilhandhabung. Eine Seilzugmaschine mit einer Zugkraft von 40 Tonnen z.B. benötigt ein spezielles Zugseil mit einem Durchmesser von 25 mm, das ca. 3 kg pro Meter wiegt. Ein 100 m langes Zugseil ist damit etwa 300 kg schwer und nicht mehr einfach zu handhaben.In the cable pulling device according to the invention, the pulling forces required for the working stroke are applied solely by the cable pulling machine. The winch only handles the rope handling. A rope pulling machine with a pulling force of 40 tons e.g. requires a special pull rope with a diameter of 25 mm, which weighs about 3 kg per meter. A 100 m long pull rope is thus about 300 kg heavy and no longer easy to handle.

Da die Seilwinde über das Aufwickeln des Seiles hinaus keine Zugkraft aufzubringen hat, braucht sie auch nicht besonders abgestützt zu werden. Das bietet größere Freiheit bei der Anordnung der Seilwinde am Arbeitsplatz. So kann die Seilwinde entweder mit der Seilzugmaschine auf einem gemeinsamen Rahmen montiert sein. Sie kann aber auch von der Seilzugmaschine vollkommen getrennt sein. Dies hat insbesondere dann Vorteile, wenn in der Arbeitsgrube wenig Platz ist.Since the winch does not have to apply any tensile force beyond the winding of the rope, it also does not need to be particularly supported. This provides greater freedom in the arrangement of the winch in the workplace. Thus, the winch can be mounted either on a common frame with the cable pulling machine. But it can also be completely separated from the cable machine. This has advantages especially if there is little space in the working pit.

Vorzugsweise ist der Antrieb der Seilwinde über einen auf den Seilzug ansprechenden Schalter abschaltbar. Sowie also das Seil beim Aufwickeln durch die Seilwinde gestrafft wird, wird der Antrieb der Seilwinde abgeschaltet.Preferably, the drive of the winch can be switched off via a responsive to the cable switch. As soon as the rope is tightened during winding by the winch, the drive of the winch is switched off.

Die Seilzugmaschine selbst kann in an sich bekannter Weise als Linearantrieb ausgebildet sein, der beispielsweise einen Arbeitshub und einen Leerhub hat. Der Antrieb der Seilwinde und der Seilzugmaschine kann elektrohydraulisch erfolgen, wobei beispielsweise die Ölzufuhr zum Antrieb der Seilwinde bei Stillstand oder einem Leerhub der Seilzugmaschine unterbrochen ist. Die elektrische Steuerung für die Seilwinde und die Seilzugmaschine kann über dieselben Bedienungselemente erfolgen.The cable puller itself can be designed in a manner known per se as a linear drive, for example, has a power stroke and a Leerhub. The drive of the winch and the cable pulling machine can be done electro-hydraulically, for example, the oil supply to drive the winch at a standstill or a dead stroke of the cable pulling machine is interrupted. The electrical control for the winch and the cable machine can be done via the same controls.

In Figur 1 ist schematisch ein Stück Boden 10 mit einem Bohrloch 12 dargestellt, in das eine Leitung eingezogen werden soll. Ebenso könnte es sich hierbei um eine Leitung handeln, durch die beispielsweise ein Splittwerkzeug gezogen werden soll. An die Bohrung 12 schließt sich ein vertikaler Kanalisationsschacht 14 an. Auf der Erdoberfläche 16 steht eine erfindungsgemäße Seilzugvorrichtung 18, die eine als Linearantrieb ausgebildete Seilzugmaschine 20 und eine Seilwinde 22 umfasst. Bei der in Figur 1 dargestellten Ausführungsform sind der Linearantrieb 20 und die Seilwinde 22 gegeneinander gestellt. Die Seilwinde 22 und der Linearantrieb 20 können auch auf einem gemeinsamen Rahmen montiert sein, der auch fahrbar sein kann. Der Linearantrieb für sich ist an sich bekannt. Er hat Seilklemmen 24 und 26 zum Erfassen eines Zugseiles 28, das über ein nicht dargestelltes Umlenkelement am Boden des Kanalisationsschachtes 14 aus dem Bohrloch 12 herausgezogen wird. Der Linearantrieb 20 arbeitet alternierend, d.h. mit einem Arbeitshub, währenddessen das Zugseil 28 mit den oberen Seilklemmen 24 um eine bestimmte Länge gefördert wird, und mit einem Leerhub, währenddessen das Zugseil 28 mit den unteren Seilklemmen 26 in seiner Position gehalten wird und die zum Ziehen bestimmten Seilklemmen 24 in ihrer Arbeitsposition zurückkehren.In FIG. 1 schematically a piece of ground 10 is shown with a borehole 12 into which a conduit is to be drawn. Likewise, this could be a line through which, for example, a split tool is to be pulled. At the bore 12, a vertical sewer manhole 14 connects. On the earth's surface 16 is a cable pulling device 18 according to the invention, which comprises a cable drive machine 20 designed as a linear drive and a cable winch 22. At the in FIG. 1 illustrated embodiment, the linear drive 20 and the winch 22 are set against each other. The winch 22 and the linear drive 20 may also be mounted on a common frame, which may also be mobile. The linear drive itself is known. He has cable clamps 24 and 26 for detecting a pull cable 28 which is pulled out of the borehole 12 via a deflector, not shown, at the bottom of the sewer manhole 14. The linear actuator 20 operates alternately, ie with a working stroke, during which the traction cable 28 is conveyed by the upper cable clamps 24 by a certain length, and with a no-load, while the traction cable 28 is held in position with the lower cable clamps 26 and the pull certain cable clamps 24 return to their working position.

Ein zur Bewegung der Seilklemmen dienendes Hydraulikaggregat ist in Figur 3 dargestellt und mit 30 bezeichnet. An der Seilzugmaschine 20 ist eine Steuereinheit 32 angeordnet, in der sich ein die Seilzugmaschine 20 steuerndes Hydraulikventil sowie die elektrische Steuerung befinden. Die Steuereinheit 32 kann mit einer in Figur 4 dargestellten Fernbedienung 34 verbunden werden, die einen Handgriff 36, ein Anschlusshebel 37 und einen Betätigungsschalter 38 hat. Die Fernbedienung hat den Vorteil, dass die Bedienungsperson sich nicht in der Nähe der Seilzugmaschine 20 aufhalten muss. Unter bestimmten Bedingungen ist dies aus Sicherheitsgründen auch nicht zulässig.A serving for moving the cable clamps hydraulic unit is in FIG. 3 represented and designated 30. At the cable pulling machine 20, a control unit 32 is arranged, in which there are a cable control machine 20 controlling hydraulic valve and the electrical control. The control unit 32 may be provided with an in FIG. 4 shown remote control 34 are connected, which has a handle 36, a connecting lever 37 and an operating switch 38. The remote control has the advantage that the operator does not have to be in the vicinity of the cable pulling machine 20. For security reasons, this is also not permitted under certain conditions.

Die Druckleitung des Hydraulikaggregats 30 wird mit dem Druckfluideingang der Seilzugmaschine 20 verbunden. Deren Druckfluidausgang ist mit dem Druckfluideingang der Seilwinde 22 verbunden, deren Druckfluidausgang wiederum über eine Rücklaufleitung mit dem Hydraulikaggregat 30 in Verbindung steht.The pressure line of the hydraulic unit 30 is connected to the pressure fluid input of the cable pulling machine 20. Its pressure fluid outlet is connected to the pressure fluid inlet of the winch 22, whose pressure fluid outlet is in turn connected via a return line to the hydraulic unit 30 in connection.

Von der Seilzugmaschine 20 führt eine nicht dargestellte Steuerleitung zur Seilwinde 22. Selbstverständlich ist auch eine Stromversorgungsleitung zwischen dem Hydraulikaggregat 30 und der Seilzugmaschine 26 vorgesehen.From the cable machine 20 performs a control line, not shown for winch 22. Of course, a power supply line provided between the hydraulic unit 30 and the cable pulling machine 26.

In Figur 2 erkennt man an der Seite der Seilwinde 22 eine hydraulische Steuereinheit 40 sowie eine elektrische Steuereinheit 42 der Seilwinde 22. Die hydraulische Steuereinheit beinhaltet mehrere elektrisch angesteuerte Hydraulikventile.In FIG. 2 can be seen on the side of the winch 22, a hydraulic control unit 40 and an electrical control unit 42 of the winch 22. The hydraulic control unit includes a plurality of electrically controlled hydraulic valves.

Die von dem Linearantrieb 20 geförderte Seillänge wird von der Seilwinde 22 aufgewickelt. Die Seilwinde 22 hat nur soviel Zug aufzubringen, dass sie das Seil aufwickeln kann. Für den Arbeitshub wird sie dagegen nicht eingesetzt. Strafft sich beim Aufwickeln das Zugseil 28, so wird durch einen auf die Zugkraft am Seil ansprechenden Schalter der Antrieb der Seilwinde 22 abgeschaltet. Im Übrigen ist die Steuerung der Seilwinde 22 so ausgelegt, dass die Seilwinde nur dann betrieben wird, wenn der Linearantrieb 20 einen Arbeitshub ausführt.The rope length promoted by the linear drive 20 is wound up by the winch 22. The winch 22 has only so much train to apply that it can wind up the rope. It is not used for the working stroke. Tightens when pulling the pull rope 28, the drive of the winch 22 is turned off by a responsive to the tensile force on the rope switch. Incidentally, the control of the winch 22 is designed so that the winch is operated only when the linear drive 20 performs a power stroke.

Bei der in Figur 2 dargestellten Ausführungsform sind gleiche Teile wieder mit gleichen Bezugszeichen versehen. Die Ausführungsform gemäß Figur 2 unterscheidet sich von jener der Figur 1 dadurch, dass die Seilwinde und der Linearantrieb voneinander getrennt sind. Der Linearantrieb 20 ist in einem Arbeitsschacht 44 angeordnet und stützt sich an der Wand des Arbeitsschachtes, an der das Bohrloch 12 mündet, über einen Stützrahmen 46 ab. Die Seilwinde 22 dagegen ist auf der Erdoberfläche 16 angeordnet. Die Funktionsweise der Seilzugvorrichtung gemäß Figur 2 ist jedoch die gleiche wie bei der Ausführungsform nach Figur 1.At the in FIG. 2 illustrated embodiment, like parts are again provided with the same reference numerals. The embodiment according to FIG. 2 is different from that of FIG. 1 in that the winch and the linear drive are separated from each other. The linear drive 20 is arranged in a working shaft 44 and is supported on the wall of the working shaft, at which the borehole 12 opens, via a support frame 46. The winch 22, however, is disposed on the earth's surface 16. The operation of the cable pulling device according to FIG. 2 however, it is the same as in the embodiment of FIG FIG. 1 ,
