Definitions

  • the invention relates to a support or tension rope with a sheathing.
  • the invention also relates to a method and a device for producing such a rope.
  • plastic sheathing does not withstand the aggressive influences of the atmosphere, especially in conurbations or industrial areas, for a sufficiently long time.
  • Plastic coatings also do not have sufficient resistance to UV radiation.
  • the rope is provided with a metallic sheathing in the form of a tight tube enclosing the rope made of a corrosion-resistant material, which offers permanent protection in the case of support or tensioning ropes.
  • EP-A 0 173 350 shows a method which nevertheless makes it possible to provide already installed ropes, in which no rope end is exposed, with a sheathing in the form of a dense metal tube.
  • the metallic cladding tube is formed on the rope that has already been inserted into a structure, in that in a tube, forming and folding station, which is set up on an anchoring area of the rope, at least one metal band, preferably two bands, is a sheath is formed.
  • the metal strips are advanced in the longitudinal direction of the rope and arched around the rope in the forming and folding station and tightly folded together along their abutting side edges running in the longitudinal direction of the rope.
  • the tube formed in the form and folding station is pulled over the rope.
  • a disadvantage of the known method is that pulling forward the tube formed in the forming and folding station is extremely difficult when it comes to large, free rope lengths with a corresponding sag.
  • the invention is based on the object in this regard to provide a support or tension rope, the sheathing is designed so that it can also be attached to ropes already installed in structures or structures, regardless of whether it is large free Rope lengths with a corresponding sag.
  • a cladding tube made of helically wound metal band is provided, the cladding tube is not formed in a stationary forming and folding station, from which it would have to be pushed or pulled over the rope, i.e. the tension elements, but the envelope is in one winding and folding process progressing over the length of the rope.
  • the invention is therefore suitable for rope lengths of any size with a corresponding sag.
  • cladding tube for example copper, stainless steel or the like.
  • the metal strip forming the sheathing tube can also be provided with an additional protective coating, for example galvanized or tinned.
  • a sealing element for example a sealing strip extending in the longitudinal direction of the fold, can be inserted into the abutting surfaces of the fold. If the fold is carefully designed using customary folding techniques, for example if a double fold or a rolled fold is produced, the seal can be completely sealed without the use of additional sealing elements.
  • An elastic compliance of the sheathing in the longitudinal and transverse directions of the pipe can be achieved by a deformable zone which extends in the longitudinal direction of the metal strip and is deformable in the transverse direction of the strip. It is particularly advantageous if part of the fold itself serves as a deformable zone. To form the deformable zone, however, a separate corrugation extending in the longitudinal direction of the strip can also be provided in the metal strip.
  • the side edges of the turns of the metal strip are connected to one another by a double fold, which consists of five adjacent layers, of which three layers consist of sections of the side edge of a band and two layers of sections of the side edge of the be adjacent band are formed.
  • a double fold which in the finished state forms a rib projecting essentially radially from the lateral surface of the tube, can be pressed together with a force which acts essentially in the longitudinal direction of the tube. This can be important if the rope is surrounded by a relatively soft mass, for example if the rope is wrapped with a rubber band, for example, on the outside of which the metallic sheathing tube is seated.
  • the invention also relates to a method provided for the production of the rope according to the invention, which consists in that a metal tube is produced as a sheathing by helically winding a metal strip around the rope with adjacent turns and the side edges of adjacent turns of the strip by forming a tight, in The longitudinal direction of the tape can be connected to one another without interruption of the continuously extending fold.
  • the metal band can be wound directly onto the rope or onto a flexible mass that may surround the rope, for example a rubber or plastic band tied around the rope.
  • the method can also be carried out in such a way that the sheathing tube is produced in such a way that its inside diameter is larger than the outside diameter of the rope, that is to say there is a gap between the rope and the metallic sheathing.
  • a split sleeve the wall thickness of which is adapted to the clear width of the space to be formed between the rope and the tube, can be provided as a displaceable winding dome on the rope on which the metal strip is wound.
  • the intermediate space thus formed between the rope and the sheathing tube can subsequently be filled with a flexible filler mass.
  • the casing can be checked for gas tightness by means of a pressure test in which the intermediate space is filled with a pressurized gas.
  • the invention also relates to a device for producing a metallic sheathing on a support or tension rope.
  • the device has a divided, rotatable winding body, which comprises the cable and carries a supply roll of the metal strip from which the sheathing tube is wound.
  • Tape guide, tape profiling and folding tools are connected to the winding body. When the winding body rotates around the rope to be wound, the rotating tools ensure the tape tension required during winding.
  • an electric motor drive for generating the rotary movement of the winding body.
  • the non-rotating part of the device which carries the drive and which can be moved along the rope together with the winding body is supported against the reaction torque generated by the drive, for example by a stabilizing weight or a support arm which is supported on an adjacent rope possibly extends next to the rope on which the winding process is carried out.
  • the figures show a rope 1, which in the present example is a built-in suspension rope of an already existing rope bridge.
  • the essential parts of a device which serves to provide the cable 1 with a metallic sheathing in the form of a tube 3 sealingly enclosing the cable 1 are shown in FIGS. 1 and 2.
  • the device has a support body 5, which is designed as a hollow metal housing, which is designed to be divisible into two housing halves, so that it can be attached to the cable 1 clamped on both sides, the housing halves being indicated by a fastening flange indicated by dashed lines in FIG. 1 7 are screwed together.
  • the support body 5 is mounted on the cable 1 so as to be longitudinally displaceable by means of a plurality of tensioning and guide rollers, of which only one is shown in FIG. 1 and is designated by 9.
  • the rollers 9 can be attached to different bearing points 11 of an associated support arm 13, which in turn is pivotably mounted on the support body 5 and is supported on the support body 5 via a spring element 15, the position of the roller 9 and the roller 9 against that Rope 1 and Wegedne biasing force of the spring element 15 are adjustable by an adjusting nut 16.
  • annular disk-shaped bearing body 17 which can also be divided into two halves, is rotatably mounted, specifically on a bearing ring 19 concentric with the housing of the supporting body 5, on which a plurality of pairs of rollers 20, which serve for axial guidance, and a plurality of rollers 21 run for radial guidance .
  • a geared motor 25 is flanged to the side on the support body 5, the pinion 26 of which meshes with an internal ring gear 27 of the bearing body 17.
  • the number of teeth of the pinion 26 and the ring gear 27 and the gear reduction of the geared motor 25 are selected so that the bearing body 17 can be driven at a speed which is suitable for a winding process in which a metal strip 29 is wound around the cable 1, whereby , as will be explained in more detail below, the metal tube 29 surrounding the cable 1 is formed from the metal band 29.
  • a winding body is firmly connected to the bearing body 17, which in the present exemplary embodiment is designed as a circular winding frame, designated as a whole as 31, which essentially centrally surrounds the cable 1, which extends through a round inner opening 33 of the winding frame 31 .
  • the winding frame 31, like the supporting body 5 and the bearing body 17, is also divided so that it can be brought into position on a relevant rope 1 clamped on both sides, the halves of the winding frame 31 being connected to one another by means of fastening flanges 35 only indicated in FIG. 2 are screwable.
  • the winding frame 31 is arranged at an angle to the plane of rotation of the bearing body 17 carrying it, the angle of inclination being adjustable by means of adjustable connecting members 37 and 38, via which the winding frame 31 is connected to the bearing body 17 (FIG. 1).
  • the winding frame 31 has two mutually parallel washers 39 and 41, which are connected to one another by means of inner connecting bolts 43 and outer connecting bolts 45 located on the circumference, sleeves 47 seated on the bolts 43 and 45, the annular discs 39 and 41 from one another Keep a distance that corresponds essentially to the width of the flat, not yet machined metal strip 29.
  • a supply roll 49 made of the still flat, unworked metal strip 29 is accommodated in the annular space between the inner bolts 43 and the outer bolts 45, the sleeves 47 of the inner bolts 43 carrying the supply roll 49.
  • the metal strip 29 runs from the innermost turn of the supply roll 49 via a strip guide device, which is formed from two curved guide strips 51 and 52, to the circumference of the rope 1 to be wound.
  • a strip guide device which is formed from two curved guide strips 51 and 52, to the circumference of the rope 1 to be wound.
  • a plurality of bending rollers 53 are mounted, which form a profiling station, which profile the continuous band 29 on both side edges 67 and 69 (FIG. 3) in several bending steps in the manner as shown in FIGS. 1 and 3 and 4 on the far left can be seen.
  • This profiling of the side edges of the band 29 prepares it for the formation of a double fold 75 (FIG. 3) by means of which the helically adjacent turns of the band 29 wound around the cable 1 are connected to one another, so that the closed metal tube is on the cable 1 3 is created as a casing.
  • the double fold 75 is produced in three steps with three folding tools, of which only one is shown completely in FIG. 1 and is designated as a whole by 55.
  • This folding tool 55 is adjustably arranged on a carrier 57, one end 59 of which is screwed to the bearing body 17.
  • Carriers 61 and 62 for the two other folding tools, one of which is indicated in FIG. 1 with a broken line and designated 63, are shown schematically in FIG. 2.
  • Fig. 3 shows the individual folding steps at 71, 72 and 73, which are carried out to form the metal tube 3, in more detail.
  • the tapered profiled band 29 is wound with its profiled side edge 67, which is on the right in the drawing, over the left-hand profiled side edge 69 of the previously laid turn in order to prepare the fold.
  • the first stage in the formation of the fold that is to say the state after the first folding step, is shown at 71 in FIG. 3.
  • the configuration of the fold after the second folding step is shown at 72.
  • FIG. 3 shows the completed double fold 75 at 73.
  • the pressing force required to produce a completely tight fold, with which the double fold 75 is pressed together is directed along the outside of the tube.
  • Fig. 3 shows on the left outer turn of the metal band 29 a sealing band 79 inserted as a sealing element in the inside of the profiled side edge 67, which is omitted in the drawing at 71, 72 and 73 for reasons of clarity. It should be noted, however, that if the double fold 75 is carefully formed, complete tightness can be achieved without inserting a sealing tape.
  • the fold 75 When using a double fold 75, which represents a rib projecting radially on the jacket of the tube 3, the fold 75 itself can form a deformable zone which enables thermal expansion of the tube 3 by an outer layer of the fold 75, designated 81 in FIG the adjacent, marked 82 slightly within the elastic limits, is spread. In this case, changes in length of the tube 3 can be compensated for by elastically yielding, moving the layers 81 and 82 of each fold 75 closer together or bringing the layers 81 and 82 closer together.
  • Fig. 4 shows another possibility of forming a deformable zone in the form of a bead 83.
  • the bead 83 like the profiling on the side edges 67 and 69 of the band 29, is produced as it passes through the group of rollers 53 in the profiling station.
  • Fig. 4 shows the use of a split sleeve 85 as a displaceable winding mandrel, which is moved in accordance with the progress of the winding process on the cable 1 in the longitudinal direction, so that the tube 3 wound from the band 29 is given an inner diameter corresponding to the outer diameter of the sleeve 85 .
  • an intermediate space 87 Between the rope 1 and tube 3 there is an intermediate space 87, the inside width of which corresponds to the wall thickness of the sleeve 85.
  • This intermediate space 87 is later filled with a resilient filler mass, optionally after the finished tube 3 has been checked for gas tightness beforehand by means of a pressure test in which the intermediate space 87 is filled with a compressed gas.
  • the supply roll 49 of the band 29, which is provided for forming the metal tube 3 is e.g. is a copper band, a band made of stainless steel or the like, placed on the sleeves 47 of the inner bolts 43 of the winding frame 31, the band 29 forming the winding 49 after removing the outer bolts 45 and their sleeves 47 from the outside can be wound up.
  • the setting of the angle of inclination of the winding frame 31 to the axis 23, about which the rotational movement takes place during the winding process, is carried out in accordance with the pitch of the helical windings with which the band 29 is placed around the cable 1 by adjusting the adjustable connecting members 37 and 38.
  • the angle of inclination depends on the diameter of the rope 1 and the width of the turns, i.e. the width of the band 29 used.
  • the tape 29 runs from the innermost turn of the supply roll 49 through the tape guide strips 51 and 52 and over the profiling station formed by the bending rollers 53 to the circumference of the rope 1 and is deposited there in the turns of the winding frame 31 in adjacent turns, the side edges of which by the folding tools , see the folding tool designated 55 in FIG. 1, are folded together.
  • This folding tool 55 also serves, as it were, as a guide member that is displaced in the longitudinal direction of the cable 1 during the rotary movement by the finished fold 75 formed, the screw pitch of which is corresponding, which results in a longitudinal movement of the device movably mounted on the cable 1 by means of the rollers 9 .
  • the tension required in the band 29 for the winding process results during the winding process due to the frictional forces which the band guiding and processing devices, i.e. the sleeves 47 which carry the innermost turn of the winding 49, the guide strips 51, 52 and the bending rollers 53 exercise the band 29 moving relative to them.
  • the counter-torque generated on the support body 5 of the device by the driving force of the geared motor 25 is compensated for by a counterweight (not shown) connected to the support body 5.
  • a counterweight (not shown) connected to the support body 5.
  • a cross-piece extending from the supporting body 5 to the adjacent rope in question can also be provided to support the torque on which the supporting rope is slidably guided.
  • a metal tube consisting of several metal tapes can be produced.
  • Each turn of the winding frame creates several turns on the rope and connects them by folding.
