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.
