Description

82665

The present invention relates to a package for pipeline components, a strong, weather- and frost-resistant plastic pipe 5 and at least one conductor for accommodating it, comprising a coil drum on which the plastic pipe is wound, wherein at least one end of the coil drum is provided with a removable cover. with a central shaft hole, the conductor or conductors being fitted inside the spool drum.

The pipeline for which the package according to the invention is intended and the various pipeline construction components related thereto are described in FI patent applications 883990-883996, whereby patent application 883994 discloses the basic construction of the pipeline.

Conventional, familiar with cable and overhead line techniques, the method of packaging cables and wires and pipes is to wind them into wooden, plastic or metal coils. The products in question are delivered by means of such coils and are dismantled at the installation site by fitting the coil to a shaft raised on the coil stands, which allows the coil to rotate, allowing the coiled product to be disassembled directly, for example when installing cables. Sometimes thin wires or cables may also be unwound from the spool 25 by pulling them over the smooth-edged flange of the spool, either directly or using special guides. The mounting wires and some other wires are also packed in bundles or coils so that they can be pulled out from the center of the bundle through an opening 30 formed in the center of the package surrounding the bundle.

The pipeline, thus consisting of a pipe made of strong, abrasion-, weather- and frost-resistant plastic and the wires or cables with plastic sheaths or coatings inside it, can be delivered from the factory 35 or the warehouse to customers in principle in two different forms. The cables can be installed inside the pipe already at the 82665 2 factory, ie the delivery takes place as a ready-made cable. Another option is to supply the pipe and conductors, which may be one or more, for example four ... five pieces, separately from each other and to pull the conductors into the pipe only during the installation phase. The finished pipeline, in which the pipelines are thus already ready inside the pipe, is most naturally packed on a large reel, or if a long delivery is required in one piece, it is packed in a wagon or platform, for example, in a known manner for submarine transport and packaging.

In practice, however, the most common method of delivery of the pipeline will be, when the technical and other aspects of the installation are taken into account, the latter method of delivery, ie separate delivery. In this case, the tube is wound on a large coil 15 and the conductors are each wound on their own coils. Of course, it is possible to place all the conductors on the same coil either side by side or it is also possible to use a coil with its own compartment for each conductor. Similarly, the conductors could be packaged and delivered in bundles either together or separately bundled.

However, there are a number of disadvantages associated with these known packaging methods. First, numerous coils take up a lot of space and require a lot of handling in storage, transportation, and installation situations. For example, a standard three-phase pipeline for three-phase power transmission requires six coils, one large pipe coil, and five smaller conductor coils, namely, three end conductors and a neutral and protective conductor. Correspondingly, a large amount of coil cover material is required, for example boarding, which results in a lot of fastening and disassembly work for the covers. Returning numerous empty reels also incurs a lot of storage, forwarding and chartering costs. Furthermore, the placement of separate conductor coils in the pipe drawing locations of the conductors creates difficulties in taking up a lot of space and requires additional control devices as well as coil braking devices and labor. The supply of conductors with separate coils alone poses risk factors, as it is more likely that some of the conductor coils will be damaged or lost. Arranging the conductors on common bundles or coils, on the other hand, binds the arrangement and selection of conductors in advance too much and does not allow for last-minute changes.

The object of the present invention is at least mainly to eliminate the above-mentioned problems. This is achieved by means of a package according to the invention, which is characterized in that the shaft hole is formed as a conductor guide for the conductors of the centrally disassembled conductor bundles arranged inside the coil-drum. Thus, in the solution according to the invention, the space in the drum of the large pipe coil is utilized by placing the pipelines included in the delivery 15 there. The pipe in the pipeline needs a large coil, the drum of which must also be large enough in diameter due to the relatively large bending diameter required by the pipe. In this case, there is enough space in the center of the coil, its drum, for all the conductors of the 20 pipelines corresponding to the length of the pipe. With a suitable pipe coil structure and pipe packaging methods, the drum space can be utilized sensibly and one package can be obtained for the separate delivery of the entire pipeline.

____ The package according to the invention will now be described in more detail with reference to the accompanying drawing, in which Figure 1 shows a blank of the package according to the invention, Figure 2 shows the end of the empty package according to Figure 1 and Figure 3 shows the package according to Figures 1 and 2 with the tube and conductors packed therein. .

Figure 1 shows an exemplary embodiment of a package according to the invention. The tubular coil 6 shown in Fig. 1 comprises, for example, a generally cylindrical coil drum 3 made of metal tubes, the ends of which are connected to wheel coil flanges 7 and 8, which are positioned centrally with respect to the coil drum 3 and provided with centrally located holes 9 and 5 in the coil discharge. for the shaft used. According to the invention, the second coil flange 8 is provided with a removable end plate 4 corresponding in diameter to the coil drum 3 5, in the middle of which the shaft hole 5 is located. This hole is preferably rounded in one way or another, for example by means of a metal ring, so that it can be used, if necessary, as a pull-out guide for the conductors placed in the drum 3.

In Fig. 3, a pipe coil 6 similar to that shown in Figs. 1 and 2 is packed with pipeline pipe 1 on the one hand and conductors to be routed to the pipeline on the other hand as conductor bundles 2. The pipeline pipe 1 is wound on a coil drum 3 between coil flanges 7 and 8. The tubes 1 are surrounded by a coil cover 15 10, which may be, for example, a metal or plastic lamella mat. Wiring harnesses 2 are arranged inside the coil drum 3. In the case shown in Fig. 3, these wiring harnesses are formed so that they can be disassembled centrally from the middle of the wiring harness by pulling the wires out through the guide and shaft 20 hole 5. In this way, it is not necessary to remove the cable bundles from inside the coil drum 3 even when drawing the cables into the pipe 1. Of course, the detachability of the end plate 4 would also make it possible to take other types of cable bundles 2 out of the spool drum before disassembling them.

In Figure 3, the conductors are shown arranged as conductor bundles 2. Of course, it would also be possible to place the conductors in the coil drum in other ways as well. For example, the wires could be wound side by side on one spool inside the spool drum 3, or they could be wound in their own flanged separators, or each wire could be wound on its own narrower spool, which would be placed in succession on the spool drum 3. In large tubular spools that it allows various unloading and control devices to be placed inside the coil drum 5 82665, allowing the conductors to be unwound from the coils over their flanges without removing the conductor coils from the drum.

The conductors could also be placed in the drum on one bundle that can fit in the drum side by side in coils-5, or each conductor bundled in its own bundle and the bundles placed in the stern channel in the drum, as shown in Fig. 3. From the point of view of maintaining the degrees of freedom, the use of separate cable bundles 2 is most advantageous.

The wiring harnesses may be bare or wrapped in the drum, for example with plastic or paper wrapped around the bundle. When pulling the wires, the bundles do not have to be removed from the drum, but the wires are disassembled by pulling the wires out of the center of the bundle through the shaft hole 5 in the drum cover and acting as a guide. All or the required number of wires can be pulled out at the same time.

Depending on the pulling head used to pull the wires, the wires twist around each other, i.e. in a way they repeat if the pulling head is fixed, when the rotating pull heads are used, on the other hand, the wires do not twist around each other.

In the case of separate wire bundles 2, intermediate guides can be placed between the bundles to help the wires exit the bundles and to prevent entanglement of the wires. The intermediate guides can be, for example, plates with a circular smooth-edged hole or a grid that rests on grooves in the inner surface of the drum of the tubular coil.

Packaging packages have been described above, in which the conductors 30 are arranged almost directly inside the coil drum 3. It would also be conceivable to place in the drum 3 a \ 'conductor cassette in which the conductors are pre-packed in one or more unshielded coils or are packed · ... in a cassette in bundles or bundles with shield wraps.

*: ** 35 Each conductor may also have its own conductor cassette, · »Λ 82665 6 which is placed in the drum stern.

Such a conductor cassette may be a cylindrical metal or plastic container or frame with a removable lid at least at one end provided with a round-edged guide hole for pulling out the conductors. The cassette can also have holes at both ends, so that the shaft that may be needed to handle the coil can also be pushed through the cassette without removing the conductor cassette from the drum when the coil is rotated with the coil stand. The use of separate cable bundles in the cassette is also the most advantageous for the preservation of light degrees of refraction and any kind of handling.

The advantage of the cassette solution can be added that it is also convenient for pipeline installation work, as a separate ka-15 set is easy to place in the appropriate place of the piped pipeline route for laying the conductors. The wires are pulled from the cassette through the guide hole in the cover in the same way as the wires are pulled from the drum.

Apart from the embodiments described above, the tube reel 6 can also be implemented in such a way that it is made to be dismantled, whereby space savings are achieved both in the storage and transport of empty reel packages. In this case, the pipe coil is formed by the flanges of the pipe coil and a conductor cassette acting as a drum, to which the flanges can be fastened and locked in place in several ways, for example by means of a bayonet fastening.

The package according to the invention and its various embodiments have been described above only in connection with some exemplary cases. Thus, for example, the packaging coil itself, in which the described embodiment has a cage-shaped drum part formed of tubes, to which the flanges of the coil made of tubes were attached, for example by welding, can also be made of metal tubes of varying shape or also. other materials such as wood or plywood. The coil structure can, of course, also be open at both ends 7 82665 and be provided with a removable end plate. The spool drum, on the other hand, can be a solid or perforated metal cylinder or made of lamellae. Furthermore, separate additional guides can be used inside the drum between the wiring harnesses. Such additional guides can be, for example, metal or plastic plates with a guide hole, which rest on the inner surface of the drum or in the grooves, knobs or cavities therein. The unwindable coil, in turn, can also be formed in such a way that the coil drum is formed from a lamella-10 slat, which is fixed as a cylinder in the grooves of the end flanges, or the conductor cassette is made collapsible or its cylindrical part is made of a lamella mat. All of the above-mentioned alternative embodiments and other alternative structures apparent to those skilled in the art are considered to be within the scope of the appended claims.
