Description

Die Erfindung betrifft eine Vorrichtung zur Montage von im wesentlichen vertikal aufzustellenden, aus aufeinanderzusetzenden Elementen bestehenden Bauteilen, z.B. von Hochspannungsleitungsmasten, Beleuchtungspylonen, Türmen usw. Die Erfindung hat besondere Bedeutung bei der Montage durch Helikopter.The invention relates to a device for assembling components which are to be set up substantially vertically and consist of elements to be placed on top of one another, e.g. of high-voltage power poles, lighting pylons, towers, etc. The invention is of particular importance in the assembly by helicopter.

Bei der bisherigen Montage von mehrteiligen Leitungsmasten wird am oberen Ende eines jeden Mastelementes ein Bund angebracht, mittels dessen das folgende, darauf gesetzte Mastelement angeschraubt werden kann. Hierzu müssen Monteure zum oberen Ende des bereits aufgestellten Mastelementes emporsteigen und das folgende, vom Helikopter herangeführte Element genau über das bereits gesetzte Element bewegen bzw. zentrieren. Darauf kann das zweite Element abgesenkt werden, wonach beide Elemente aneinandergeschraubt werden können.In the previous assembly of multi-part utility poles at the upper end of each mast element is attached to a collar, by means of which the following, set it, M can be screwed astelement. To do this, fitters have to ascend to the upper end of the already erected mast element and move or center the following element brought up by the helicopter exactly over the element that has already been set. The second element can then be lowered, after which both elements can be screwed together.

Dieses Verfahren ist aufwendig und für die Montagepersonen gefährlich.This process is complex and dangerous for the assembly personnel.

Der Erfindung liegt die Aufgabe zugrunde, eine besonders in dieser Hinsicht verbesserte Vorrichtung zu schaffen.The invention has for its object to provide a particularly improved device in this regard.

Die Erfindung liegt in einem am oberen Ende des zu montierenden Elementes befestigbaren, im wesentlichen nach oben konisch zusammenlaufenden Körper, dessen oberes Ende vom Tragglied einer Montageeinrichtung, z.B. eines Helikopters oder eines Kranes, erfassbar ist.The invention resides in a body which can be fastened to the upper end of the element to be assembled and converges essentially conically upwards, the upper end of which is supported by the supporting member of an assembly device, e.g. a helicopter or a crane.

Hierdurch wird es möglich, das folgende, mittels des Helikopters herangeführte Element mit seinem unteren, hohlen Ende über das obere Ende des konischen Körpers des bereits aufgestellten Elementes zu führen und langsam abzusenken.This makes it possible to guide the lower element, which is brought up by means of the helicopter, with its lower, hollow end over the upper end of the conical body of the element already set up and slowly lower it.

Das folgende Element wird dann beim Absenken infolge der -konischen Ausbildung des Körpers selbsttätig auf das bereits stehende Element vertikal zentriert. Bedienungspersonen sind dabei nicht erforderlich.The following element is then automatically centered vertically on the already standing element when lowering due to the conical shape of the body. Operators are not required.

Bei einer Ausführungsform der Erfindung enthält der Körper an seinem Umfang angeordnete Stäbe, die mit dem unteren Ende an dem zu montierenden Element angebracht sind und sich nach oben in einen Zentrierkopf fortsetzen. Soll z.B. ein polygonaler, etwa achtkantiger Mast montiert werden, so können die Umfangsstäbe an den Kanten der Mastelemente, zweckmässig an der Innenseite angeordnet sein. Das folgende Mastelement wird dann selbsttätig beim Absenken auch über die Kanten des bereits gesetzten Mastelementes geführt. Es erfolgt also eine Rotationszentrierung, ohne dass Bedienungspersonen benötigt werden.In one embodiment of the invention, the body contains rods arranged on its periphery, which are attached with the lower end to the element to be mounted and continue upwards into a centering head. Should e.g. a polygonal, approximately octagonal mast are mounted, the circumferential rods can be arranged on the edges of the mast elements, expediently on the inside. The following mast element is then automatically guided over the edges of the mast element already set when it is lowered. So there is a rotation centering without the need for operators.

Weitere Merkmale ergeben sich aus der folgenden Beschreibung von Ausführungsbeispielen in Verbindung mit der Zeichnung und den Ansprüchen.Further features result from the following description of exemplary embodiments in conjunction with the drawing and the claims.

  • Fig. 8 bis 12 veranschaulichen die Anwendung der Vorrichtung.8 to 12 illustrate the application of the device.

Die als Ganzes mit 1 bezeichnete Montagevorrichtung enthält z.B. auch in Fig. 1 nach oben konisch zusammenlaufende Stäbe 2. Jeder Stab besitzt eine untere Abkröpfung 3, die parallel zur Achse 4 der Montagevorrichtung 1 und eines Elementes 5 eines zu montierenden Mastes 16 (Fig. 11) verlaufen. Die Abkröpfungen 3 sind am Innenumfang 6 (Fig. 6,7) des Mastelementes 5 angeschweisst und zwar jeweils bei einer Längskante 7 des Mastelementes. Der Abkröpfungswinkel A (Fig. 6) der Stäbe 2 kann z.B. ca. 30° betragen.The assembly device designated as a whole by 1 contains e.g. also in FIG. 1 rods 2 which converge conically upwards. Each rod has a lower offset 3 which runs parallel to the axis 4 of the mounting device 1 and an element 5 of a mast 16 to be mounted (FIG. 11). The bends 3 are welded to the inner circumference 6 (FIGS. 6, 7) of the mast element 5, in each case at a longitudinal edge 7 of the mast element. The offset angle A (Fig. 6) of the bars 2 can e.g. approx. 30 °.

Die oberen Enden der Umfangsstäbe 2 besitzen Abkröpfungen 8, die parallel zur Achse 4 verlaufen und Schrägungen 9 aufweisen. Die Abkröpfungen 8 sind an einem Distanzrohrstück 11 angeschweisst. Dieses besitzt an dem in Fig. 1 oberen Ende eine sattelförmige Ausnehmung 12 und Schrägungen 13 (Fig. 3).The upper ends of the circumferential bars 2 have bends 8 which run parallel to the axis 4 and have bevels 9. The bends 8 are welded to a spacer tube 11. At the upper end in FIG. 1, this has a saddle-shaped recess 12 and bevels 13 (FIG. 3).

Die Ausnehmung 12 ist durch einen Tragbügel 14 überbrückt.The recess 12 is bridged by a bracket 14.

In die so entstehende Oeffnung 15 kann z.B. der Haken einer Trageinrichtung 21 eines Helikopters 17 (Fig. 8-12), eines Kranes oder dgl. eingreifen.In the opening 15 thus created, e.g. the hook of a support device 21 of a helicopter 17 (Fig. 8-12), a crane or the like.

Bei der Anwendung nach Fig. 8 bis 12 wird das Element 5 eines zu errichtenden Mastes 16 mittels eines Helikopters 17 gemäss Fig. 8 vom Lagerplatz 20 hochgezogen und entsprechend Fig. 9 an die Baustelle 18 herangebracht, wo es auf die beiden bereits gesetzten, übereinander gestülpten Mastelemente 5a, 5b gesetzt werden soll.8 to 12, the element 5 of a mast 16 to be erected is pulled up from the storage location 20 by means of a helicopter 17 according to FIG. 8 and brought up to the construction site 18 according to FIG. 9, where it is placed on top of the two already placed inverted mast elements 5a, 5b to be placed.

Der Helikopter 17 führt die untere Oeffnung 19 des hohlen Mastelementes 5 entsprechend Fig. 10 über den Tragbügel 14 und das Distanzrohrstück 11 der Montagevorrichtung 1. Bei der darauf folgenden Absenkung des Elementes 5 gelangt dieses auf das darunter befindliche Element 5a. Dabei wirken das Distanzrohrstück 11 und anschliessend die Stäbe 2 als Zentriermittel sowohl hinsichtlich der Achse 4 (Vertikalzentrierung) wie auch hinsichtlich der Kanten 7 (Rotationszentrierung). Das Element 5 erhält dadurch die in Fig. 11 dargestellte Position, in der es vertikal steht und in der die Kanten 7 übereinander stehen. Schliesslich wird vom Helikopter 17 aus entsprechend Fig. 12 die Trageinrichtung 21 ausgehängt, so dass der Helikopter wegzufliegen und gegebenenfalls das nächste Mastelement herbeibringen kann.The helicopter 17 guides the lower opening 19 of the hollow mast element 5 according to FIG. 10 over the support bracket 14 and the spacer tube piece 11 of the mounting device 1. When the element 5 is subsequently lowered, it reaches the element 5a located underneath. The spacer tube piece 11 and then the rods 2 act as centering means both with respect to the axis 4 (vertical centering) and with regard to the edges 7 (rotational centering). The element 5 thereby receives the position shown in FIG. 11, in which it is vertical and in which the edges 7 are one above the other. Finally, the helicopter 17 is unhooked from FIG. 12, so that the helicopter can fly away and, if necessary, bring the next mast element.

Beim Absenken gemäss Fig. 10, 11 kann das untere Ende 19 gegebenenfalls auf die Schrägungen 9 gelangen und darüber abgleiten. In der Regel wird es auch auf die Schrägpartien 22 der Umfangsstäbe 2 gelangen und über diese abrutschen und sich dabei sowohl auf die Achse 4 wie auch auf die Kanten 7 zentrieren.When lowering according to FIGS. 10, 11, the lower end 19 can possibly reach the bevels 9 and slide over them. As a rule, it will also reach the sloping parts 22 of the circumferential bars 2 and slide over them and thereby center both on the axis 4 and on the edges 7.

Die ganze, bisher beschriebene Montage kann sich vollziehen, ohne dass Bedienungs- oder Hilfspersonen am Mast 16 benötigt werden. Nach erfolgter Montage kann das jeweils oberste Mastelement z.B. mittels einer Zug- oder Spannvorrichtung mehr oder weniger weit abwärts getrieben werden.The entire assembly described so far can be carried out without the need for operating or auxiliary personnel on the mast 16. After assembly, the top mast element can e.g. be driven more or less far down by means of a pulling or tensioning device.

Jedes Mastelement 5, 5a, 5b besitzt oben eine Montagevorrichtung 1. Die Montagevorrichtungen können am Mast 16 verbleiben. Gegebenenfalls braucht das letzte, zu montierende Mastelement 5 oben keine Montagevorrichtung 1 zu haben, sondern es genügen hier z.B. einfache Tragösen am oberen Ende des Elementes. Die Zentrierung erfolgt jeweils durch die Montagevorrichtung 1 des darunter befindlichen Mastelementes.Each mast element 5, 5a, 5b has a mounting device 1 at the top. The mounting devices can remain on the mast 16. If necessary, the need to have last astelement to-install M 5 above no mounting device 1, but suffice eg simple eyebolts on the upper end of the element. The centering takes place in each case by the mounting device 1 of the mast element located below.

Abgewandelte Ausführungsformen ergeben sich, wenn die Montagevorrichtung z.B. für einen Mast von rundem Querschnitt verwendet werden soll. In diesem Fall können mehr oder weniger als acht Umfangsstäbe 2 vorgesehen sein. Eine Rotationszentrierung fällt dann weg, es ist nur die Vertikalzentrierung auf die Achse 4 notwendig.Modified embodiments result when the mounting device e.g. to be used for a mast with a round cross-section. In this case, more or less than eight circumferential bars 2 can be provided. Rotational centering is then omitted, only vertical centering on axis 4 is necessary.

Anstelle der Stäbe 2 kann auch ein durchgehender Umfang aufweisender, konischer, etwa glockenförmiger Körper benutzt werden. Die Schrägpartie 22 darf nicht zu kurz sein. Der Winkel A wird in der Regel nicht wesentlich über 30° betragen, damit das aufzusetzende Element abrutschen und sich zentrieren kann. Auch die Schrägungen 9, 13 sind dazu bestimmt, dass das Element 5 beim Absenken nicht aufsitzen kann.Instead of the rods 2, a continuous, conical, approximately bell-shaped body can be used. The sloping section 22 must not be too short. The angle A will generally not be significantly above 30 ° so that the element to be put on can slide and center. The bevels 9, 13 are also intended so that the element 5 cannot sit on when lowering.
