Definitions

  • the invention relates to a cable drum for reeling electrical cables and lines with the cylindrical drum core consisting of core strips on which the cable layers are supported and the side walls which form the lateral boundary for the cable layers and which are composed of side segments connected to one another and with spokes and whose free outer edge is covered by an outer hoop, the outer hoop simultaneously holding the side segments together on the outside, in the middle of which there is provided an axis of rotation held by the spokes, about which the entire drum can be rotated, and wherein the spokes simultaneously connect the outer hoop and the drum body and in turn as Bracket for sandwich panels serving as side segments.
  • Cables are often used as support elements for bridges, anchor chains and the like. ⁇ . Things used. These numerous individual wires of such cables give such a wire rope high strength, with a corresponding number of such wires being joined to form an overall structure, depending on the load-bearing capacity. Especially for the transport of electricity, electrical cables with a large number of copper wires are provided, which, like the cables provided as support elements, are wound up for intermediate storage and transport on cable drums, with appropriate arrangement ensuring that the individual layers do not influence one another or even endanger.
  • such a cable drum must be suitable for secure storage and support of the individual cable layers and, moreover, be so stable that it can be used both as a work drum and as a circulation drum, ie for transport from the manufacturer to the customer.
  • Cylindrical cable drums are mostly used because they can be unrolled on the floor or rotated around an axis, so that the cables can be easily and easily placed or unrolled.
  • the area of application As a work drum or circulating drum, almost no differences have been made in known drums. They look similar to the cable drum known from DE-OS 38 42 162, in which the side walls are made of wood.
  • the individual boards are connected to one another, partly overlapping and transversely to one another, in order to create sufficiently stable walls in this way.
  • the drum body itself consists of individual boards, which are each attached to the ring or connected to a ring on the narrow sides, so that the correspondingly stable cylinder results, the boards being referred to as core strips.
  • the electric drums intended for use in the factory must have particular stability, so that the use of walls made of metal is known here. However, these have the problem that the side walls can deform, so that it is no longer possible to wind the cables properly.
  • a disadvantage of the cable drums as a whole is that they are made from a relatively valuable material, with the fact that not every wood is suitable for processing.
  • the invention is therefore based on the object of a circulating drum and, in case of doubt, also as particularly to be stabilized Factory drum to create usable cable drum that is easy to repair and at the same time user-friendly and can expect a long service life.
  • the outer hoop has a releasable connection, that the spokes have a groove embedded in the side edges on both sides and that the sandwich plates have corresponding edges which are designed as springs.
  • the necessary reeling and reeling work can be carried out in the manufacturing plant as well as the transport, in particular the electrical cable, to the customer or customer.
  • the spokes give the side walls sufficient stability, on the one hand, and flexibility in the side walls comparable to the wooden cable drums, in the longitudinal direction of the spokes.
  • the cable drum is designed so that the spokes have a groove embedded in the side edge on both sides and that the sandwich plates have corresponding edges that are designed as tongues, which gives the side walls the advantageous flexibility in the plane of the side walls, because the sandwich plates are virtually in the spokes - and can be pushed or moved back and forth.
  • the sandwich panels are only supported and fixed by the outer hoop and the inner inner hoop. When opening such a cable drum, for example, even if it is occupied with a corresponding number of cable layers, would not be destroyed because of the entire side wall or at giving way to the side walls. It is also the case that handling and repair are easy, because by simply loosening the outer tire the possibly damaged sandwich panels can be replaced by simply pulling them out of their tongue and groove connection. Damage to the side walls and thus to the individual sandwich panels can occur in particular through the forks of the forklift trucks if the individual cable drum has to be removed from the truck, for example.
  • the stiffening is preferably improved in that the sandwich panels have corresponding sawtooth-engaging side edges with the adjacent panels.
  • This interlocking of the stiffening plates with one another results in an advantageous partial overlap and thus a gain in stability, since each of the individual spokes is automatically connected to two such sandwich plates, whereby advantageous reinforcement is also achieved, particularly in the radial direction. If no screw connections are made, the overlaps still increase the stability of the individual sandwich panel while maintaining flexibility.
  • the spokes and the sandwich panels on the inside facing the drum body have an attachment supporting the core strips and that a U-shaped support ring is provided to accommodate the core strips.
  • a U-shaped support ring is provided to accommodate the core strips.
  • the necessary rigidity in the case of particularly reinforced work drums is also specified in the transition area between core strips and side walls, in that the core strips of the drum body and the inner disk or the inner tire are designed to interlock and are connected to one another by means of tensioning screws. Clamping screws of this type are also used for the circulating drum, but in the work drum they are primarily used to firmly fit the core strips and the side walls together.
  • the invention provides that the sandwich panels and the other plastic parts made of 30 to 90% polyurethane containing, preferably premixed with hard integral foam granules and crushed to less than 10 mm, with binder (isocyanate ) finely dusted and then pre-compressed at about 2 NN / mm 2 and post-compressed at a low pressure of less than 4 NN / mm 2 and then continuously expanded, recycled polyurethane foam. It is particularly advantageous that the individual parts are each brought into the intended and usable form, in each case for the intended type, without rework being necessary.
  • the cable drum can be assembled and finished by simply screwing on the sandwich panels or inserting the steel framework made of outer tire, inner tire, inner web and spokes, which has already been mentioned several times.
  • the entire production time of such cable drums can thus be reduced considerably, and, as already mentioned, an environmental problem, namely recycling, is also advantageously solved here at the same time of used plastic.
  • outer webs, the spoke are integrally formed on the outer hoop. This makes it easy to connect the two parts. At the same time, even after loosening the connection of the outer tire, only the area can be unscrewed that has to be replaced due to destruction or impairment. This training is particularly suitable for the very stable and rigid work drum.
  • the outer hoop is U-shaped and has an inner shoulder ring which is fitted into an annular recess in the spokes and sandwich plates.
  • the outer hoop which is also used to store and hold the sandwich panels, thus lies around the outer edges or edges of the sandwich panels and fixes them, but can also be easily removed if individual sandwich panels have to be replaced for any reason.
  • the outer hoop As a connection for the outer hoop, it is provided in particular that it has a recess at both ends into which an insert shaped like a ammonia pastille is fitted, preferably welded. By loosening the weld seam, the outer hoop can be loosened if necessary, which is then removed altogether, for example to replace some or all of the sandwich panels if this proves necessary and expedient.
  • Other connections are also conceivable, but the described has the advantage that it gives the outer ring the necessary strength.
  • the invention is characterized in particular by the fact that cable drum types are created which, regardless of the size, are highly flexible and yet practical also have the necessary stability without the need for time-consuming preparatory work or high production costs.
  • the cable drum as such consist of a spoke frame into which plastic parts, namely sandwich panels, are inserted and screwed or inserted in order to increase the stability and to achieve the necessary final stability, so that the desired goal of high stability or advantageous flexibility is achieved.
  • the reduction to a few components is advantageous, and these can additionally be connected to one another in a simple and expedient manner.
  • 1-3 show a side view of a cable drum 1 which is not part of the invention, which is a work drum which has a high degree of stability, the drum body 2 receiving the cables being visible only with respect to the cylindrical outer edge.
  • the side walls 3 and, when cut, the side wall 4, which is composed of individual components, are clearly visible, as will be explained further below.
  • the entire cable drum 1 is often unrolled during transport, wear on the outer edge being prevented by the fact that an outer tire 6 made of steel is used up here.
  • This outer tire 6 is connected to the drum body 2 by radially arranged spokes 7, 8, 9. Screw connections are provided here, which are not specifically identified.
  • the individual spokes 7, 8, 9 are provided with transverse bores 10, 11. Via these transverse bores 10, 11 in the spokes 7, 8, 9, it is possible to effectively fix the sandwich plates 12, 13 which connect the individual spokes 7, 8, 9 to one another and are designed as stiffening plates.
  • the individual stiffening plates 12, 13 are designed on the side edges 14, 17 in such a way that they form a toothed surface with one another, wherein in this area they coincide with the respective spoke 7; 8th; 9 are connected.
  • the individual stiffening plates 12, 13 must have bores 18, 19 corresponding to the transverse bores 10, 11, with FIG. 1 already making clear that these bores 18, 19 are always combined into bore groups 20, 21.
  • the individual stiffening plates 12, 13 are not only fixed at several points of the respective spokes 7, 8, 9, but they also result in the longitudinal direction of the spokes 7 , 8, 9 an advantageous stiffening.
  • Fig. 2 further shows that the two side walls 3, 4, which consist of the steel frame made of outer tires 6, spoke 7, 8, 9 and drum body 2 are connected to each other.
  • a U-shaped inner web 28, which is assigned to the inner hoop 26 and also forms it, is open toward the inside 27.
  • This U-shaped inner web 28 is provided with a screw hole 30 through which the tensioning screw 29 can be passed.
  • the inner hoop 26 is stabilized via the inner belt 31 and corresponding stiffening parts in such a way that the individual tensioning screws 29 can also be effectively braced in such a way that they are simultaneously fixed with the notches 32, 33 forming the drum body 2.
  • the narrow sides 35 of the core segments 32, 33 are designed so that they can be inserted into the corresponding areas of the inner tire 26, so that they can be fixed simultaneously with the tightening of the clamping screw 29.
  • the individual core segments 32, 33 lie flat against one another on the longitudinal sides 36, it also being conceivable that they overlap one another in order in this way to also result in an effective dense surface.
  • an inner disk 34 is clamped, a bore 37 being generally made in these inner disks 34, which enables an axis or the like to be pushed through.
  • the side walls 3, 4 are shown without the stiffening plates 12, 13 or the outer plate and the inner plate 22, 23.
  • the inner pane 34 is also clarified in a similar manner, so that it can be seen that overall a very stable design of the side walls 3, 4 has been achieved.
  • Fig. 3 shows such a stiffening plate 12 or 13 or an outer plate 22 or inner plate 23.
  • this is a very versatile single part, from which essentially the side walls 3, 4 can be put together without special care having to be taken. All individual parts have the shape shown in FIG. 3. It is also conceivable to give the individual stiffening plates 12, 13 a different shape, each corresponding to the adjacent plates. It is important, however, that the individual stiffening plates 12, 13, which are designed to correspond to one another, are designed to interlock with each other at the side edges 14, 17, as is illustrated by the embodiment according to FIG. 3.
  • FIGS. 4-12 illustrate the solution according to the invention, a section through a side wall 3 being shown again. This figure illustrates that clamping the stiffening plates 12, 13 results in a very stable side wall 3, 4 overall. It is also clear from this section that the individual stiffening plates 12, 13 or the outer plate 22 and the inner plate 23 interlock, so that advantageous stability is also achieved in the longitudinal direction of the spokes 7, 8, 9. Corresponding is made clear by the hatching.
  • the holes 18, 19, 18 ', 19' provided serve once for fixing the stiffening plate 12 and once for the stiffening plate 13. This is illustrated by appropriate reference numerals.
  • the holes 18, 19 are made as blind holes, so that the screws can be effectively countersunk.
  • the spokes 7, 8, 9 are screwed to the outer hoop 6 according to FIGS. 5 and 6.
  • the two representations illustrate that for this purpose 6 outer webs 39, 40 are attached to the outer hoop are attached, into which the respective spoke 7, 8, 9 is inserted, the effective fixing then taking place by inserting the connecting screw 38.
  • FIG. 7 shows this area, here the additionally attached stop stiffeners 42 are shown, which contribute to additional stabilization, similar to the stop stiffener 41 shown in FIG. 6 in the area of the spoke 7, 8, 9 and outer tire 6 connection.
  • the composite cable drum is made up of just a few different steel components and consist of the same PU molded parts.
  • the PU lining has a very smooth surface, which has advantages when it comes to reeling the cables. Nails are completely dispensed with, so that damage to the cables and lines cannot occur as a result.
  • the advantages of the interchangeability of molded parts in the event of damage or wear have also already been pointed out.
  • the molded parts are identical for all drum sizes, so that considerable cost advantages can also be achieved in this way. It is also advantageous that at least the side walls are now completely waterproof, cannot expand or warp due to the influence of water, and that the molded parts made of plastic as such are not conductive.
  • FIG. 8 shows a cable drum 1 'provided as a circulation drum.
  • the axis of rotation 5 is shown in the center, about which the entire cable drum 1 'and of course also in the illustration according to FIG. 1, the cable drum 1 can be rotated.
