Description

Die Erfindung betrifft einen Montageaufsatz zum Ein- und Ausbauen von Steigrohren eines Brunnens durch einen hohlen Ständer hindurch, mit einem Mast, der an seinem oberen Ende eine Umlenkvorrichtung mit einer Umlenkrolle aufweist, und einem Zugglied, das über die Umlenkrolle geführt, an einem seiner Enden zum Anhängen eines Steigrohrs und am anderen Ende zum Anhängen an eine Hebevorrichtung ausgebildet ist.The invention relates to an assembly attachment for installing and removing riser pipes of a well through a hollow stand, with a mast which has a deflection device with a deflection roller at its upper end, and a tension member which is guided over the deflection roller at one end is designed for attaching a riser pipe and at the other end for attaching to a lifting device.

Zur Wasserversorgung der Landbevölkerung in Entwicklungsländern in den Trockengebieten der Erde werden oft Brunnenpumpen eingesetzt. Sie werden im allgemeinen durch Muskelkraft betrieben und fördern Grundwasser aus Tiefen bis zu 100 m. Meist sind die Aufstellungsorte der Brunnenpumpen weit abgelegen und, wenn überhaupt mit Landfahrzeugen, nur mit geländegängigen Kraftwagen zu erreichen.Well pumps are often used to supply the rural population with water in developing countries in the arid regions of the world. They are generally operated by muscle power and pump groundwater from depths of up to 100 m. The locations of the well pumps are usually far away and, if at all with land vehicles, can only be reached with off-road vehicles.

Für Montage-, Wartungs- und Reparaturarbeiten an solchen Brunnenpumpen ist es bisher erforderlich, schweres Hubgerät an den Einbauort zu bringen. Dies setzt voraus, daß entsprechend ausgerüstete Montagetrupps, eine Organisation der nötigen Einsatzfahrten und entsprechende finanzielle Mittel vorhanden sind. Häufig ist dies nicht der Fall, und deshalb unterbleiben in vielen Fällen notwendige Wartungs- oder Reparaturarbeiten an den Brunnenpumpen.For assembly, maintenance and repair work on such well pumps, it has previously been necessary to bring heavy lifting equipment to the installation site. This presupposes that appropriately equipped assembly teams, an organization of the necessary operational trips and corresponding financial means are available. Often this is not the case, and therefore in many cases there is no maintenance or repair work on the well pumps.

So ist aus der US-A-1 632 935 ein Montageaufsatz der genannten Gattung bekannt, bei dem der Mast unabhängig von dem hohlen Ständer eines Brunnens und in erheblichem seitlichem Abstand von diesem am Boden abgstützt und durch Halteseile in solcher Schräglage gehalten ist, daß ein Haken, der an einem senkrecht von der Umlenkrolle herabhängenden Strang eines Seils befestigt ist, senkrecht über der Mitte des Ständers hängt. Entsprechendes gilt für einen aus der US-A-1 732 466 bekannten, ebenfalls gattungsgemäßen Aufsatz nur mit dem Unterschied, daß dort anstelle eines Hakens ein jochartiges Hebegeschirr vorgesehen und an einer beweglichen Umlenkrolle aufgehängt ist.Thus, from US-A-1 632 935 an assembly attachment of the type mentioned is known, in which the mast is supported independently of the hollow stand of a well and at a considerable lateral distance from it on the ground and is held in such an inclined position by tethers that a The hook, which is attached to a strand of rope hanging vertically from the pulley, hangs vertically above the center of the stand. The same applies to a similarly known attachment from US-A-1 732 466 only with the difference that instead of a hook a yoke-like lifting gear is provided there and is suspended from a movable deflection roller.

In beiden Fällen lassen sich Steigrohre nur dann ohne die Gefahr des Verkantens und Verklemmens durch den hohlen Ständer hindurch ein- und ausbauen, wenn der Mast durch die zugehörigen Halteseile in einer solchen Schräglage gehalten ist, daß der über die Umlenkrolle zum Steigrohr heruntergeführte Strang des Seils oder sonstigen Zuggliedes genau längs der Achse des hohlen Ständers verläuft.In both cases, riser pipes can only be installed and removed through the hollow stand without the risk of jamming and jamming if the mast is held in an inclined position by the associated holding ropes in such a way that the strand of the rope led down to the riser pipe via the deflection roller or other tension member runs exactly along the axis of the hollow stand.

Diese Bedingung wird bei jedem der beiden bekannten gattungsgemäßen Montageaufsätze im allgemeinen nur dann erfüllt sein, wenn der Aufsatz von geübtem und besonders sorgfältig arbeitendem Personal aufgestellt worden ist, das auch darauf geachtet hat, ob der hohle Ständer selber genau senkrecht steht. Bei ungenügender Sorgfalt oder Erfahrung muß damit gerechnet werden, daß zwischen der Achse des Ständers und der Richtung des Zuges, der vom Zugglied auf Steigrohre ausgeübt wird, eine mehr oder weniger große Winkelabweichung besteht, die dann dazu führt, daß eine Komponente der auf die Steigrohre ausgeübten Kraft seitlich zur Innenwand des hohlen Ständers gerichtet ist und Reibungswiderstände erzeugt, die einen einwandfreien Ein- oder Ausbau der Steigrohre behindern. Bei unzweckmäßiger Handhabung können Steigrohre verbogen werden und sich infolgedessen derart fest im hohlen Ständer verklemmen, daß beim Versuch, sie wieder herauszuziehen, das Zugglied reißt.This condition will generally only be met in each of the two known generic mounting attachments if the attachment has been set up by trained and particularly carefully working personnel who have also paid attention to whether the hollow stand itself is exactly vertical. With insufficient care or experience, it must be expected that between the axis of the stand and the direction of the train, which is exerted by the tension member on risers, there is a more or less large angular deviation, which then leads to a component of the risers applied force is directed sideways to the inner wall of the hollow stand and creates frictional resistances that hinder the proper installation or removal of the risers. If handled improperly, risers can be bent and consequently get stuck in the hollow stand so tightly that when you try to pull them out, the tension member breaks.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine einfache, leichte und billige Vorrichtung zu entwickeln, die vorzugsweise zusammen mit jeder Brunnenpumpe oder Gruppe solcher Pumpen geliefert wird und an oder nahe deren Aufstellungsort bleibt, vorzugsweise in der Obhut einer für den Pumpenbetrieb verantwortlichen Person, die ohne besondere Ausbildung imstande sein soll, die Vorrichtung bei Bedarf an der Brunnenpumpe aufzustellen und dadurch die erforderlichen Wartungs- oder Reparaturarbeiten mindestens vorzubereiten.The invention is therefore based on the object of developing a simple, lightweight and inexpensive device which is preferably supplied together with each well pump or group of such pumps and remains at or near their installation location, preferably in the care of a person responsible for pump operation, who without special training should be able to set up the device on the well pump when necessary and thereby at least prepare the necessary maintenance or repair work.

Die Aufgabe ist erfindungsgemäß durch einen Montageaufsatz der eingangs beschriebenen Gattung gelöst, bei dem der Mast achsparallel zum Ständer in einem Kopfteil und einem Fußteil gehalten ist, die am Kopf- bzw. Fußende des Ständers befestigt oder befestigbar sind, und der Radius der Umlenkrolle zumindest annähernd mit dem Abstand zwischen den Längsachsen von Mast und Ständer übereinstimmt.The object is achieved by an assembly attachment of the type described above, in which the mast is held axially parallel to the stand in a head part and a foot part, which are attached or can be fastened to the head or foot end of the stand, and the radius of the deflection roller is at least approximately corresponds to the distance between the longitudinal axes of the mast and stand.

Ein erfindungsgemäßer Montageaufsatz für eine bestimmte Tragkraft läßt sich leichter und einfacher gestalten, da der Mast in jeder beliebigen Stellung des Zuggliedes von Biegebelastungen fast vollständig freigehalten ist. Dementsprechend läßt sich der Montageaufsatz leichter befördern und einfacher aufstellen als bisher für vergleichbare Zwecke übliches Hubgerät von gleicher Hubhöhe und Tragkraft. Ein durchschnittlich kräftiger Mann kann den gesamten erfindungsgemäßen Montageaufsatz über längere Strecken zu Fuß tragen oder bei nicht allzu schwierigen Geländeverhältnissen mit dem Fahrrad transportieren, so daß ein einziger Montageaufsatz in geeigneten Fällen für mehrere, nicht allzu weit voneinander entfernte Brunnenpumpen verwendet werden kann.An assembly attachment according to the invention for a certain load capacity can be made lighter and simpler, since the mast is kept almost completely free from bending loads in any position of the tension member. Accordingly, the mounting attachment can be transported more easily and set up more easily than hitherto conventional lifting devices of the same lifting height and load capacity. An average strong man can carry the entire mounting attachment according to the invention on foot over long distances or transport it by bike in not too difficult terrain, so that a single mounting attachment can be used in suitable cases for several well pumps that are not too far apart.

Die erforderliche Stabilität des Montageaufsatzes am Aufstellungsort ergibt sich dadurch, daß der Mast am Ständer der Pumpe abgestützt wird. Der Ständer ist wegen der im Betrieb der Pumpe auftretenden Belastungen in jedem Fall hinreichend kräftig gestaltet, um auch den Belastungen standzuhalten, die bei Aufstellung und Benutzung des erfindungsgemäßen Montageaufsatzes auftreten können.The required stability of the mounting attachment at the installation location results from the fact that the mast is supported on the stand of the pump. The stand is designed to be sufficiently strong in any case because of the loads occurring during the operation of the pump in order to withstand the loads that can occur when installing and using the mounting attachment according to the invention.

Die Hebevorrichtung kann beispielsweise eine Seil- oder Kettenwinde oder ein mit intermittierender Seilklemmung arbeitender.Hubzug handelsüblicher Bauweise sein. Als Hebevorrichtung für nicht allzu tiefe Brunnenpumpen mit entsprechend leichtem Steigrohrstrang kann ein zusätzliches Seil vorgesehen sein, das über mindestens eine zusätzliche, am Ständer verankerbare Umlenkvorrichtung läuft und mit Muskelkraft gezogen wird.The lifting device can for example be a winch or chain winch or a hoist working with intermittent rope clamping be of common construction. An additional rope can be provided as a lifting device for not too deep well pumps with a correspondingly light riser pipe run, which runs over at least one additional deflection device that can be anchored to the stand and is pulled with muscular strength.

Vorzugsweise ist mindestens ein Oberteil des Mastes mit Umlenkvorrichtung, Zugglied und Hebevorrichtung unlösbar verbunden. Dadurch wird verhindert, daß die einzelnen Teile des Montageriggs zweckentfremdet werden und verlorengehen können. Die unlösbare Verbindung kann einfach dadurch hergestellt sein, daß das durch Hebe- und Umlenkvorrichtung hindurchgeführte Zugglied an seinen beiden Enden unlösbare Beschläge aufweist.Preferably, at least an upper part of the mast is non-detachably connected to the deflection device, tension member and lifting device. This prevents the individual parts of the assembly rig from being misused and being lost. The non-detachable connection can be made simply by the fact that the tension member guided through the lifting and deflecting device has non-detachable fittings at both ends.

Es ist ferner zweckmäßig, wenn die Hebevorrichtung eine Anhängevorrichtung aufweist, die am Ständer derart verankerbar ist, daß das Zugglied an einer der Ständerachse in bezug auf die Mastachse diametral gegenüberliegenden Stelle in die Hebevorrichtung einläuft. Dadurch wird der Mast bei Benutzung des erfindungsgemäßen Montageaufsatzes von Biegemomenten weitgehend freigehalten ; er wird im wesentlichen nur auf Druck belastet und kann dementsprechend schlank und leicht gestaltet sein.It is also useful if the lifting device has a hitch that can be anchored to the stand such that the tension member runs into the lifting device at a position diametrically opposite the stand axis with respect to the mast axis. As a result, the mast is largely kept free of bending moments when using the assembly attachment according to the invention; it is essentially only subjected to pressure and can accordingly be slim and light.

Wenn die Hebevorrichtung als Hubzug ausgebildet ist, weist sie vorzugsweise zusätzlich eine Führung auf, mit der sie am Mast senkrecht verschiebbar geführt ist. Dadurch wird die am Ständer verankerte Hebevorrichtung zusätzlich stabilisiert, so daß sie nicht pendeln kann, was ihre Handhabung erschweren und die Symmetrie des Zuggliedes in bezug auf die Mastachse stören würde.If the lifting device is designed as a hoist, it preferably additionally has a guide with which it is guided so as to be vertically displaceable on the mast. As a result, the lifting device anchored to the stand is additionally stabilized so that it cannot oscillate, which would make its handling more difficult and would disturb the symmetry of the tension member with respect to the mast axis.

Wenn die Hebevorrichtung dagegen als Seil-oder Kettenwinde ausgebildet ist, dann ist die Anhängevorrichtung zweckmäßigerweise mit dem Ständer starr kuppelbar.If, on the other hand, the lifting device is designed as a cable or chain winch, then the hitching device can expediently be rigidly coupled to the stand.

Das Kopfteil ist vorzugsweise eine Platte, die zum Einstecken des Mastes ein Loch und zum Verankern der Hebevorrichtung eine weitere Befestigungsstelle aufweist.The head part is preferably a plate which has a hole for inserting the mast and a further fastening point for anchoring the lifting device.

Der Transport des erfindungsgemäßen Montageaufsatzes kann dadurch erleichtert sein, daß der Mast ein Oberteil aufweist, an dem die Umlenkvorrichtung befestigt ist, und daß als Unterteil ein Steigrohr verwendet wird. Wenn eine Brunnenpumpe eingebaut wird, bleibt meist mindestens ein Steigrohr übrig, das dann als Bestandteil des Mastes verwendet werden kann.The transport of the mounting attachment according to the invention can be facilitated in that the mast has an upper part to which the deflection device is attached and that a riser is used as the lower part. If a well pump is installed, there is usually at least one riser pipe that can be used as part of the mast.

Schließlich ist es vorteilhaft, wenn das Zugglied an seinem dem Ständer zugeordneten Ende eine Hahnepot aufweist, an die wahlweise die Antriebsvorrichtung oder ein Joch zum Heben des Steigrohrstrangs anhängbar ist.Finally, it is advantageous if the tension member has a tap at its end assigned to the stand, to which the drive device or a yoke for lifting the riser pipe string can be attached.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer schematischen Zeichnung mit weiteren Einzelheiten erläutert. Es zeigt :

  • Fig. 2 Einzelheiten aus Fig. 1 in einem vergrößerten senkrechten Schnitt.
An exemplary embodiment of the invention is explained below with the aid of a schematic drawing. It shows :
  • Fig. 1 is a partially shown as a vertical section side view of the ground and. Parts of a well pump arranged above the floor with an assembly attachment according to the invention and
  • Fig. 2 details of Fig. 1 in an enlarged vertical section.

Die Brunnenpumpe hat ein Fundament 10 aus Beton, von dem sich ein Mantelrohr 12 senkrecht nach unten bis in eine grundwasserführende Erdschicht erstreckt. Das Mantelrohr 12 umschließt mit radialem Abstand einen Steigrohrstrang aus Steigrohren 14, die durch Rohrkupplungen 16 miteinander verbunden und durch sternförmige Stützringe 18 im Mantelrohr 12 zentriert sind.The well pump has a foundation 10 made of concrete, from which a casing tube 12 extends vertically downwards into a groundwater-bearing layer of earth. The jacket tube 12 encloses, at a radial distance, a riser pipe line from riser pipes 14 which are connected to one another by pipe couplings 16 and are centered in the jacket pipe 12 by star-shaped support rings 18.

Auf dem Fundament 10 steht ein Ständer 20 mit einem seitlich auskragenden, plattenförmigen Kopfteil 22 und einem ebenfalls plattenförmigen Fußteil 24, das auf dem Fundament 10 festgeschraubt ist. Auf dem Kopfteil 22 ist ein Zwischengehäuse 26 befestigt, das einen Wasserauslauf 28 aufweist und eine Antriebsvorrichtung 30 trägt.On the foundation 10 is a stand 20 with a laterally projecting, plate-shaped head part 22 and a plate-shaped foot part 24, which is screwed onto the foundation 10. An intermediate housing 26 is fastened on the head part 22 and has a water outlet 28 and carries a drive device 30.

Die Antriebsvorrichtung 30 ist im dargestellten Beispiel ein Getriebe, das mit einer Handkurbel 32 antreibbar ist und seinerseits einen nicht dargestellten Wellenstrang antreibt, der sich durch den Steigrohrstrang nach unten erstreckt und mit einem schneckenförmigen Rotor gekuppelt ist. Der Rotor arbeitet in einem schneckenförmigen Stator, der im unteren Endbereich des Mantelrohrs 12 angeordnet und zusammen mit den Steigrohren 14 durch das Mantelrohr herausziehbar ist.In the example shown, the drive device 30 is a transmission which can be driven with a hand crank 32 and in turn drives a shaft train (not shown) which extends downward through the riser pipe train and is coupled to a helical rotor. The rotor works in a helical stator, which is arranged in the lower end region of the casing tube 12 and can be pulled out through the casing tube together with the riser tubes 14.

Eine solche Ausgestaltung einer Brunnenpumpe ist aus der DE-A-31 32 260 bekannt und braucht deshalb hier nicht im einzelnen dargestellt und beschrieben zu werden, zumal die Gestaltung der Brunnenpumpe als Exzenterschneckenpumpe im vorliegenden Zusammenhang ohne besondere Bedeutung ist. Die Brunnenpumpe kann beispielsweise auch als Kolbenpumpe ausgebildet sein ; in diesem Fall ist die Antriebsvorrichtung so gestaltet, daß sie die Drehung einer Handkurbel oder Schwenkungen eines Pumpenschwengels in auf- und niedergehende Kolbenbewegungen umsetzt. Solche Pumpen sind beispielsweise aus der Zeitschrift « World Water vom Februar 1983 bekannt.Such a design of a well pump is known from DE-A-31 32 260 and therefore need not be shown and described in detail here, especially since the design of the well pump as an eccentric screw pump is of no particular importance in the present context. The well pump can also be designed as a piston pump, for example; in this case, the drive device is designed such that it converts the rotation of a hand crank or swivels of a pump arm into rising and falling piston movements. Such pumps are known, for example, from the World Water magazine from February 1983.

Der Pumpe ist ein Montageaufsatz mit einem schlanken, rohrförmigen Mast 34 zugeordnet, der aus einem Oberteil 36 und einem Unterteil 38 zusammengesetzt ist. Das Unterteil 38 ist in allen Einzelheiten identisch mit einem überzähligen Steigrohr 14 samt zugehöriger Rohrkupplung 16. Die Gesamthöhe des Mastes 34 ist mindestens um die Höhe des Ständers 20 größer als die Länge jedes einzelnen Steigrohrs 14 samt Rohrkupplung 16.The pump is associated with an assembly attachment with a slim, tubular mast 34, which is composed of an upper part 36 and a lower part 38. The lower part 38 is identical in all details with a surplus riser pipe 14 including the associated pipe coupling 16. The total height of the mast 34 is at least by the height of the stand 20 greater than the length of each individual riser pipe 14 including the pipe coupling 16.

Am oberen Ende des Oberteils 36 ist eine Umlenkvorrichtung 40 angeordnet, die eine Umlenkrolle 42 aufweist. Die Drehachse der Umlenkrolle 42 schneidet die Mastachse 44 und erstreckt sich im dargestellten, aufgebauten Zustand des Montageaufsatzes im rechten Winkel zu der senkrechten Ebene, in der die Ständerachse 46 und die zu ihr parallele Mastachse 44 liegen. Die Umlenkrolle 42 hat einen Umlenkradius, der mit dem Abstand der beiden Achsen 44 und 46 übereinstimmt. Die obere Hälfte der Umlenkrolle 42 ist mit einer Schutzhaube 48 abgedeckt.At the upper end of the upper part 36, a deflection device 40 is arranged, which has a deflection roller 42. The axis of rotation of the deflection roller 42 intersects the mast axis 44 and extends in the illustrated, assembled state of the mounting attachment at a right angle to the vertical plane in which the column axis 46 and the mast axis 44 parallel to it lie. The deflection roller 42 has a deflection radius that corresponds to the distance between the two axes 44 and 46. The upper half of the deflection roller 42 is covered with a protective hood 48.

Über die Umlenkrolle 42 läuft ein Zugglied 50, das im dargestellten Beispiel von einem Seil gebildet ist, aber auch von einer Kette gebildet sein könnte. An dem einen, über dem Ständer 20 hängenden Strang des Zuggliedes 50 ist ein ringförmiger Beschlag 52 befestigt, an dem über eine Hahnepot 54 ein Joch 56 aufgehängt ist. Das Joch 56 hat eine mittige Aussparung 58, die seitlich offen und derart bemessen ist, daß die Steigrohre 14 nacheinander unterhalb ihrer Rohrkupplung 16 mit dem Joch 56 erfaßt werden können, um aus dem Mantelrohr 12 herausgezogen oder in dieses abgesenkt zu werden. Anstelle des Jochs 56 kann an der Hahnepot 54 die Antriebsvorrichtung 30 für deren Ab- oder Anbau angehängt werden, beispielsweise an zwei Wellenenden.A tension member 50 runs over the deflection roller 42, which in the example shown is formed by a rope, but could also be formed by a chain. On the one strand of the tension member 50 hanging above the stand 20, an annular fitting 52 is fastened, on which a yoke 56 is suspended via a tap 54. The yoke 56 has a central recess 58 which is open at the side and is dimensioned such that the risers 14 can be grasped one after the other below their pipe coupling 16 with the yoke 56 in order to be pulled out of the casing tube 12 or lowered into it. Instead of the yoke 56, the drive device 30 can be attached to the tap pot 54 for its removal or attachment, for example on two shaft ends.

Der andere Strang des Zuggliedes 50 läuft durch eine Hebevorrichtung 60, die als handelsüblicher Hubzug mit alternierend arbeitenden Klemmbackenpaaren 62, einem Betätigungshebel 64 und einem Bremshebel 66 dargestellt ist. Die Hebevorrichtung 60 hat eine Anhängevorrichtung 68 in Form eines Hakens sowie eine rohrförmige Führung 70, mit der sie am Unterteil 38 des Mastes 34 in dessen Längsrichtung verschiebbar geführt ist. Das Zugglied 50 ist nach unten oder seitlich aus der Hebevorrichtung 60 herausgeführt und weist an seinem Ende einen weiteren Beschlag 72 auf.The other strand of the tension member 50 runs through a lifting device 60, which is shown as a commercial hoist with alternating jaw pairs 62, an actuating lever 64 and a brake lever 66. The lifting device 60 has a hitch 68 in the form of a hook and a tubular guide 70 with which it is guided on the lower part 38 of the mast 34 so as to be displaceable in its longitudinal direction. The tension member 50 is led out downward or laterally out of the lifting device 60 and has a further fitting 72 at its end.

Das Unterteil 38 des Mastes 34 ist von oben her durch ein kreisförmiges Loch 74 im Kopfteil 22 des Ständers 20 hindurchgesteckt und greift in eine hülsenförmige Halterung 76 ein, die am Fußteil 24 ausgebildet ist. Dadurch ist der gesamte Mast 34 mit dem Ständer 20 starr verbunden, so daß er keiner weiteren Abstützung bedarf.The lower part 38 of the mast 34 is inserted from above through a circular hole 74 in the head part 22 of the stand 20 and engages in a sleeve-shaped holder 76 which is formed on the foot part 24. As a result, the entire mast 34 is rigidly connected to the stand 20, so that it requires no further support.

Das Kopfteil 22 hat eine weiteres Befestigungsstelle 78 in Form eines Lochs, das auf demselben von der Ständerachse 46 ausgehenden Radius liegt wie die Mitte des Lochs 74, das die Lage der Ständerachse 46 bestimmt. Der Mittenabstand der Befestigungsstelle 78 von der Ständerachse 46 ist doppelt so groß wie der Mittenabstand des Lochs 74 von der Ständerachse. Durch das Loch 78 erstreckt sich eine Kette 80, die in die Anhängevorrichtung 68 eingehakt und mit einem Bolzen 82 am Kopfteil 22 des Ständers 20 festgelegt ist.The head part 22 has a further fastening point 78 in the form of a hole which lies on the same radius starting from the stator axis 46 as the center of the hole 74 which determines the position of the stator axis 46. The center distance of the fastening point 78 from the stator axis 46 is twice as large as the center distance of the hole 74 from the stator axis. A chain 80 extends through the hole 78 and is hooked into the hitch 68 and fixed to the head part 22 of the stand 20 with a bolt 82.

Wenn die Hebevorrichtung eine Seil- oder Kettenwinde ist, kann die Anhängevorrichtung 68 einen steifen Bügel aufweisen, der an der Hebevorrichtung befestigt und auf das Kopfteil 22 seitlich derart aufsteckbar ist, daß die Hebevorrichtung über die Anhängevorrichtung und das Kopfteil 22 starr mit dem Ständer 20 kuppelbar ist.If the lifting device is a cable or chain winch, the hitching device 68 can have a rigid bracket which is attached to the lifting device and can be attached laterally to the head part 22 such that the lifting device can be rigidly coupled to the stand 20 via the hitching device and the head part 22 is.

Als weitere Alternative zu der dargestellten Hebevorrichtung 60 kann an das Zugglied 50 ein zusätzliches Seil 84 angehängt werden, das über mindestens eine am Ständer 20 verankerte zusätzliche Umlenkrolle 86 läuft, gegebenenfalls mit mehreren solchen Umlenkrollen einen Flaschenzug bildet und ebenfalls eine mit Muskelkraft betätigbare Hebevorrichtung bildet.As a further alternative to the lifting device 60 shown, an additional rope 84 can be attached to the tension member 50, which runs over at least one additional deflection roller 86 anchored to the stand 20, optionally forms a pulley block with several such deflection rollers and likewise forms a lifting device which can be actuated with muscle power.
