Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding device for a wire for submarine installation, such as a submarine cable or a submarine water pipe, for winding a wire for installation on a seabed, such as a submarine cable or a submarine water pipe, onto a winding frame on a laying ship. The present invention relates to a winding device for a large strand of wire for laying on the seabed.

Generally, when laying this type of wire on the seabed, the wire is coiled onto a winding frame on a laying ship, the laying ship is towed to the installation site, and the wire is unwound from the winding frame at the site. It was laid on the ocean floor.

Normally, when winding or laying a filament on a laying vessel, a group of hanging rollers provided above the winding frame and an inclined guide section provided between the group of hanging rollers and the edge of the laying vessel are used. It is equipped with a guide means including.

In the prior art, this guide means is supported by a turret attached to the laying vessel, but installing the turret on the laying vessel requires a large amount of sacrificial cost, which is uneconomical.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wire winding device for seabed laying that can economically assemble a guide means.

Embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 3 show a wire winding device 1 for seabed laying of the present invention.
0, this apparatus is equipped with a laying vessel 12 having a turntable (not shown) in one half, and a filament winding frame 14 is provided on the turntable.

A coil take-up machine 16 is mounted so as to be relatively slidable on the filament winding frame 14 of the coil.
It consists of a movable roller 20 that can move in the radial direction of the wire take-up frame 14 to guide it from above the axis of the wire take-up frame 14 into the take-up frame, and a plurality of guide rollers 22 above the movable roller. ing.

In FIG. 1, reference numeral 24 is an endless track type pulling machine installed on the other side of the laying vessel 12, and the coil body 18 is pulled from the ground through a guiding means to be described later by this pulling machine. The filament is coiled onto the filament winding frame 14 by the machine 16.

The guide means 26 is a group of hanging rollers 28 disposed above the wire winding frame, and an inclined guide section that is provided between the group of hanging rollers and the take-up machine 24 and guides the wire 18 between them. 30
It consists of.

The suspension roller group 28 includes a plurality of rollers 32 arranged in an arc shape.
These rollers are rotatably supported by an arcuate roller frame 34.

Five pairs of auxiliary vertical rollers 33 are also supported by the roller frame 34, and these auxiliary vertical rollers prevent the linear body 18 from falling off in the horizontal direction.

The roller frame 34 has a suspension shaft 44 attached to the top thereof by a bracket 34a, and the suspension shaft 44 is intended to be supported by a support to be described later.

The guide means 26 is a pair of support columns 4 pivotally supported on the laying ship 12.
6, and these columns include a plurality of hollow pipes 46 flanged together, as shown in FIGS. 1 and 4.
a, the hollow pipe 46a has a spacing rod 48 between the pairs.
are mutually reinforcing.

The roller frame 34 of the suspension roller group 28 is supported with its suspension shaft 44 passing through the upper ends of a pair of support columns 46 (FIG. 3), and two roller frames stretched between both ends of the roller frame 34 and the support columns 46 are supported. It is fixed in the position shown in FIG. 1 by a stay wire 50°50'.

As shown in FIGS. 1 and 2, the strut 46 has a plurality of pairs of stay wires 5 stretched between its upper end and the laying ship 12.
2, 52', 56, and 60 are fixed in the position shown in FIG.

In addition, stay wires 50° 50', 52, 52', 56, 6
0 is such that its tension can be adjusted by a turnbuckle 54.

As shown in detail in FIGS. 5 and 6, the inclined guide section 30 is rotatably fixed between a frame pipe 58 fixed between a pair of stay wires 56 and a pair of stay wires 60. horizontal roller 62 attached to the stay wire 56
and a pair of auxiliary vertical rollers 64 which are fixed and rotatably mounted between the stay wire 60 and the stay wire 60. It is fixed by a support wire 68 stretched between the stay wires 68 and a hanging wire 70 stretched between the pair of stay wires 52.

The support wire 68 and the hanging wire 70 are also connected to the turnbuckle 54
The tension can be adjusted by

Note that the auxiliary vertical rollers 64 of these inclined guide units 66
This also prevents the striated body 18 from falling off in the lateral direction.

As shown in FIG. 1, the filament 18 is guided from the take-up machine 24 to the hanging roller 28 through a plurality of inclined guide units 66.

According to the present invention, as described above, the guide means including the suspension roller group and the inclined guide section are supported by the strut and the stay wire that supports the strut on the laying ship, so that the oar is assembled on the laying ship as in the conventional case. It is economical because it is not necessary and sacrifice time and cost are reduced.
