Definitions
- 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., with sloping guides attached to the upper end of the elements, which are effective when the element to be placed on them.
- the upper element to be placed on this known device has no inclined guides, but is suspended from a helicopter by four individual cables. This makes it difficult to bring the element to be placed in the vertical position and center it when it is brought up.
- the four ropes must have exactly the same length.
- the invention has for its object to provide an improved assembly method, in which in particular any number of elements can be placed on top of each other, suspension, positioning and centering of the element to be placed can be easily carried out or achieved.
- the invention consists in that the inclined guides form an essentially conically converging body and continue in a carrying device, the upper end of which is carried by the supporting member of an assembly device, e.g. a helicopter or crane.
- 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.
- 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. Axial and rotation centering takes place automatically when lowering, without the need for operators.
- 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 offsets 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 °.
- 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).
- the recess 12 is bridged by a bracket 14. 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.
- 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.
- the helicopter 17 guides the lower opening 19 of the hollow mast element 5, as shown in FIG. 10, over the support bracket 14 and the spacer tube piece 11 of the assembly device 1.
- the element 5 When the element 5 is subsequently lowered, it reaches the element 5a located below it.
- 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 respect 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.
- the support device 21 is unhooked from the helicopter 17, so that the helicopter can fly away and, if necessary, bring the next mast element.
- 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.
- the entire assembly described so far can be carried out without the need for operating or auxiliary personnel on the mast 16.
- the top mast element can e.g. be driven more or less far down by means of a pulling or tensioning device.
- 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 last mast element 5 to be mounted does not need to have a mounting device 1 at the top, but here, e.g. simple lifting eyes at the upper end of the element. The centering takes place in each case by the mounting device 1 of the mast element located below.
- Modified embodiments result when the mounting device e.g. to be used for a mast with a round cross-section.
- more or less than eight circumferential bars 2 can be provided. Rotational centering is then omitted, only vertical centering on axis 4 is necessary.
- a continuous, conical, approximately bell-shaped body can be used 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.

Abstract
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., mit am oberen Ende der Elemente angebrachten, beim Setzen des darauf aufzusetzenden Elementes wirksamen Schrägführungen.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., with sloping guides attached to the upper end of the elements, which are effective when the element to be placed on them.
Bei einer bisherigen Vorrichtung dieser Art (US-A- 41 89 892) sind an einem unteren Turmelement vier schräg nach innen und oben ragende Führungsstäbe angebracht. Sie sind relativ kurz ausgebildet und ragen mit den freien Enden nach oben.In a previous device of this type (US-A-41 89 892) four guide rods projecting obliquely inwards and upwards are attached to a lower tower element. They are relatively short and protrude upwards with their free ends.
Das obere, aufzusetzende Element dieser bekannten Vorrichtung besitzt keine Schrägführungen, sondern wird durch vier Einzelseile an einen Helikopter gehängt. Es ist dadurch erschwert, das aufzusetzende Element beim Heranführen in vertikale Position zu bringen und zu zentrieren. Die vier Seile müssen hierzu exakt gleiche Länge besitzen.The upper element to be placed on this known device has no inclined guides, but is suspended from a helicopter by four individual cables. This makes it difficult to bring the element to be placed in the vertical position and center it when it is brought up. The four ropes must have exactly the same length.
Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Montageverfahren zu schaffen, bei dem sich insbesondere beliebig viele Elemente aufeinandersetzen lassen, wobei Aufhängung, Positionierung und Zentrierung des aufzusetzenden Elementes leicht durchgeführt bzw. erzielt werden können.The invention has for its object to provide an improved assembly method, in which in particular any number of elements can be placed on top of each other, suspension, positioning and centering of the element to be placed can be easily carried out or achieved.
Die Erfindung besteht darin, dass die Schrägführungen einen sich nach oben zu im wesentlichen konisch zusammenlaufenden Körper bilden und sich in eine Tragvorrichtung fortsetzen, deren oberes Ende vom Tragglied einer Montageeinrichtung, z.B. eines Helikopters oder Kranes, erfassbar ist.The invention consists in that the inclined guides form an essentially conically converging body and continue in a carrying device, the upper end of which is carried by the supporting member of an assembly device, e.g. a helicopter or crane.
Hierdurch wird es möglich, beliebig viele Elemente leicht aufeinanderzusetzen und dabei das jeweils aufzusetzende Element zentral aufzuhängen. Seine vertikale Position stellt sich von selbst ein. Bedienungspersonen zum Ausrichten der übereinanderzustülpenden Teile sind entbehrlich, Gefahr wird also völlig vermieden.This makes it possible to easily stack any number of elements on top of each other and to hang up the element to be placed centrally. Its vertical position adjusts itself. Operators for aligning the parts to be put on top of each other are unnecessary, so danger is completely avoided.
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 beim Absenken selbsttätig eine Achsial- und 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. Axial and rotation centering takes place automatically when lowering, without the need for operators.

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
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). Die Ausnehmung 12 ist durch einen Tragbügel 14 überbrückt. In die so entstehende Öffnung 15 kann z.B. der Haken einer Trageinrichtung 21 eines Helikopters 17 (Fig. 8-12), eines Kranes oder dgl. eingreifen.The upper ends of the
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
Der Helikopter 17 führt die untere Öffnung 19 des hohlen Mastelementes 5 entsprechend Fig. 10 über den Tragbügel 14 und das Distanzrohrstück 11 der Montagevorrichtung 1. Bei der darauffolgenden 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 wegfliegen und gegebenenfalls das nächste Mastelement herbeibringen kann.The
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
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
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 Trag- ösen am oberen Ende des Elementes. Die Zentrierung erfolgt jeweils durch die Montagevorrichtung 1 des darunter befindlichen Mastelementes.Each
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. 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.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
