Abstract
On the cord-like device, bellows for example, cable or lead are being placed a crust of being made up of a plurality of metal wires on the outer surface of these devices, these metal wires be with bigger fluctuation apart from along wrap up in and fastening by another crust.These metal wires are along being rolled on this device with the fluctuation direction of alternation.Second exodermis be at least one with less fluctuation apart from the metal wire that twines, it is seized on first crust with prestressing force.
Description
What the present invention relates to is Abseiling device, for example, be one and have tubular metallic member helix or annular ripple, cable or lead, placed the exodermis that metal wire more than is formed on the surface of these devices, its metal wire and by the another one exodermis it is tightened up along cloth with bigger fluctuation distance on apparatus surface.
Bellows has its advantage, and is promptly flexible and transverse strength is big.Its shortcoming then is: because existing internal pressure, during in the longitudinal direction if any very little pulling force, at first just produced flexible elongation in when load.As already known, this shortcoming can so be eliminated: promptly people are put a mesh grid on this bellows, and this net stops the elongation strain of pipe, and makes this pipe compacted to a certain extent., braider work is slow, and particularly it costs an arm and a leg for large diameter pipe.
A bellows discloses from british patent specification GB-PS 1336630, it utilize one with than great fluctuation process apart from strengthening along many crust metal wires of wrapping up in.Placing second exodermis similarly wrapping up in apart from the edge with bigger fluctuation on this first exodermis, they are being wrapped up in the desirable way edge opposite with first exodermis metal wire fluctuation direction.This its advantage of known structure is: owing to used this device exodermis to make bellows can bear the pressure bigger than conventional device basically, do not have this structure because the internal pressure of device promptly can cause the elongation of device.This known conduit shortcoming is: the method that the metal wire crust is wrapped up on this edge expends very much, and is particularly, all the more so when larger-diameter device clads crust.Processing during this pipe must: a single placement is arranged the coil of cladding metal wire along whole cephalocaudal bellows major axis rotation.
Disclose in the outer surface upper edge of a cable from Deutsche Bundespatent prospectus DE-OS 2705743 and to have wrapped up in a metal line layer, this metal carbonyl conducting layer is used as concentrated protection layer or zero potential lead in cable technology.When making this cable skin, after be rolled on the cable, also to bring fasteningly at this metal line layer with one, this band for example, can be with plastic, or also be made of metal.
A kind ofly like this have cable protective layer or the zero potential lead; its principal advantages is: when making a branch point; lead and insulation should separate fully, to this protective layer or zero lead with simple method from remaining that the cable outer surface cuts and need not cut apart.This technology, for example known in German patent DE-GM 1875570.It is absolute demand too: metal line layer is movably in the axial direction.As long as this point is arranged, known metal level can not be regarded as a cable skin that should be able to bear pulling force.
The present invention is based on this task, proposes an Abseiling device, and it can improve the pulling force that bears and particularly it also can be controlled economically comes out for large diameter device.
This task will solve in this wise: according to the present invention this metal wire with the fluctuation direction of alternation along being rolled on the device, another exodermis be at least one with the metal wire of less fluctuation apart from wrapping, it is placed on first exodermis to give pressure.Thus, when wrapping up in metal wire, cladding crust metal wire is pulled out from a fixing coil, or an also available more simple sennit equipment is processed with alternation fluctuation direction edge.Utilize the fastening metal line have than the moving distance wrapping of shortwave to make the metal wire of formation one of exodermis closely be fixed on the device again.Therefore just formed a kind of reinforced CONTACT WITH FRICTION, it shows high tension intensity and to wavy pipe extensional deformation is avoided.For what this not only simple but also cheap protective effect played a decisive role be: it is owing to give this power of pressure in essence, is wrapped up at fastening metal line under this pressure; Exodermis also works in the angle of bellows long axis direction simultaneously.This angle is suitable with 5-45 ° in practice.When the angle of relative long axis direction more hour, the effect of this protective layer is just better.But since the bending property of desired device just limited this angle can not be too little.
This fastening metal line is in the close-coupled that has formed on the cable between a cable and the cable sheath.What be all beyond one's expectations is to wrap up the cable of cable sheath according to the present invention, not because this cable sheath layer is restricted its bending property in itself.
According to a particularly advantageous configuration of the present invention, the winding of first cable cortex is surrounded angle less than 360 °, be preferably less than 180 °, this reinforces the metal wire that the metal wire skin should have such number, and promptly metal wire will be with 50% topped lives of the outer surface of cable unit at least.This point when second consideration according to the present invention also be favourable, it to cable tube with regard to the tool meaning.The diameter of metal wire is approximately the wall thickness of cable tube.Only use a wires as second cable cortex, it is wrapped up with such stress that gives, and promptly is slightly less than the yield strength limit of metal wire.By these measures, the cable sheath metal wire will be pressed on the cable unit surface, and just improve the frictional force between cable skin metal line layer and the cable unit.When this situation, promptly cable unit be a tubulose and this pipe be ripple order with zigzag shape, the practice that then conforms with purpose is: the fastening metal line is wrapped up with the fluctuation distance that almost is equivalent to the ripple pitch.This metal wire should be tied the metal wire cortex on the trough place of bellows scope, and the metal wire cortex of this cable is compressed into the trough of bellows.For the contact that also has shape therebetween with the contact of giving cable skin metal wire that pressure ties up and the power between the bellows outer surface outward.At the plastic outer layer that can also place an extrusion modling on this cable skin.
Also this possibility can be arranged, promptly outside first cable metal line cortex to wrap second cable metal line layer to anti-fluctuation direction, and with a total fastening metal line of on second metal line layer, placing these two metal line layers are tightened together, simultaneously they are compressed mutually to cable unit.
The invention further relates to the method for production cord-like device, it is characterised in that, on this cord-like device, placing one be evenly arranged in that pipe is placed outward and with bigger fluctuation apart from along a plurality of plain conductors of wrapping up in; Its fluctuation direction is to continue to change; Metal wire arranges the back and fixes with the fastening metal line of a relatively little fluctuation apart from wrapping.Basically be here: after the cable metal cortex being placed on the cable unit directly with the fastening metal coil of wire around on, can be retained on the cable unit with desirable shape to guarantee cable metal line layer.
Another configuration according to method of the present invention is that along wrapping second metal line layer, its fluctuation direction is opposite with the fluctuation direction of first metal line layer, and these two metal line layers are fixed up with a total fixing metal line.Use this measure, the tension intensity of cable unit has strengthened basically.If layer of metal line or double layer of metal line are to be very advantageous less than 360 ° of angles of contact along wrapping up in, if just better less than 180 °.More essential is: place the angle of metal line layer on the cable unit outer surface, promptly its angle with respect to the cable unit major axis is not greater than 45 ° on any metal wire placement location.If it is big that this angle is selected, be created in its long axis direction thus and reduce component.This will cause the transmission that reduces pulling force.Metal wire has very big advantage to place less than the line-spacing of assembly dia, is more preferably half less than this cord-like assembly dia.Because between fixing metal line and the cable metal line cortex and wrapping up with fastening metal line between cable metal line cortex and this cord-like device and only working in the scope of fastening metal line in principle, this measure has also caused the raising of tensile strength.
The present invention further also relates to the device for this method is implemented, this method is to make and uses along the bellows of wrapping up in cable skin, it makes a long continuously progressive metal tape form pipe according to invention, and with the device of the processing tube of its slit welding; The pipe with welding after being placed on produces undulatory ripple forming device; A sennit device of wrapping up in the ground floor cable skin with the fluctuation direction edge of alternation; The concentrated bobbin winoler that wrapping fastening metal line is used and squeezer are formed.With the sennit device be again by one a plurality of fixed in position arranged be used to put the coil of cable sheath metal wire and the driving-disc of convertible direction of rotation.
For metal wire is seized with the desired pressure that gives, the coil of wire that contains metal wire with anti-winding direction by transmission.This driving force should be greatly to produce the desired stress that gives on metal wire.
The present invention will illustrate to embodiment shown in Figure 3 and the curve map on Fig. 4 in more detail according to Fig. 1.Being primarily aimed at bellows to the explanation of figure the time carries out.Though this is used for similar cable and lead equally.
Fig. 1 represents a spiral yarn shaped corrugated metal pipe 1, a plurality of metal wires 2 on its periphery, have been placed equably as crust, this crust metal wire has a sizable fluctuation distance, promptly is exactly to wrap up in carrying out the edge with the angle of the long axis direction of bellows 1 under less than a numerical digit.All change the direction of coiled at turning point 3 at every turn.This exodermis metal wire 2 utilizes a fastening metal line 4 to seize, and it is that spiral is seized on exodermis metal wire 2 apart from quilt linearly and with less fluctuation, and fastening position.For crust metal wire 2 being avoided because the internal stress component makes the extensional of bellows 1, just must: this outer layer metal line 2 closely is placed on the outer surface of this pipe.The stress that gives that fastening metal line 4 usefulness are bigger is for this purpose seized, and the stress that meets the requirements is lower than the yield of metal wire.Because this high thrust makes the friction between bellows 1 and the exodermis metal wire 2 increase.Label 5 is that the plastic outer layer of a compacting is the typical case as requested with the vinyon.The diameter of this exodermis metal wire should be equivalent to the wall thickness of bellows 1.According to its wall thickness value of the external diameter of bellows size between 0.5 to 2 millimeter.The diameter of this fastening metal line has the same order of magnitude, as requested also should be big again.
It on Fig. 2 the diagrammatic sketch of a very favorable embodiment of the invention.Here also selected spiral yarn shaped bellows 1.Along what wrap up in, also tie up with a fluctuation distance by this fastening metal line as mode same among Fig. 1 for this exodermis metal wire 2, and this distance is equivalent to the pitch of waves of bellows 1.This fastening metal line 4 is placed in the scope of trough, like this because it gives stress to making exodermis metal wire 2 produce distortion around the wave crest of bellows 1.Because such method, to give the friction linking that stress produces except that use and also have a shape contact, this shape is got in touch the same elongation that can avoid bellows under the effect of internal pressure component with friction linking.
Tubular element described in Fig. 1 and Fig. 2 is to produce with such method: the bellows 1 that utilizes the device of not shown welded tube and ripple forming to process according to one of Fig. 3 wraps metal wire by means of a braiding machine 6 that has crust metal wire 2.This sennit device is made up of another driving porose disc 8 of a fixing porose disc 7 and an alternation rotation.If this crust metal wire with respect to bellows to hold around the angle bigger, then the distance of 7 to 8 of porose discs will be selected greatlyyer.When distance was big between porose disc 7 and 8, the diameter of the circumference that the overall diameter outline of this bellows forms less than the hole and it were fixed on the porose disc 7.The crust metal wire that comes out from porose disc 8 will be placed on the outer surface of bellows 1 by means of a so-called sennit sleeve pipe 9, fix at the directly fastened metal wire of the back of this sleeve pipe 9 metal wire.Used a so-called concentrated bobbin winoler 10 here, it is made up of the coiling arm 11 of a rotation and bobbin 12.For the fastening metal line is seized with the stress that gives of necessity, this coil 12 will be anti-the driving of coiling direction, and by this way, promptly along with the reach the standard grade stress that gives that reduces this pulling force and this fastening metal line of layer diameter of coil 12 also always keeps constant.The bellows that wraps crust 1 that should come out from bobbin winoler 10 will be loaded onto the rolled-up stock 5 of a plastics jacket layer, and its method is no longer narrated.
The curve of describing according to Fig. 4 shows the superiority of cortex of the present invention significantly.Be pressure on abscissa, and be the length deformation of representing with permillage on ordinate.Internal diameter of curve 1 expression is 140 millimeters, and external diameter is 180 millimeters, and thickness is the extensional of the bellows made of 0.3 millimeter special steel.Its pitch of waves is 4 millimeters.Can find out significantly: promptly stretch under quite little pressure at the bellows that does not have cortex and be out of shape.The curve of the bellows of curve 2 expression same-types, it has a metal wire exodermis, and it is that 0.5 millimeter single-wire is formed by 40 diameters, and it is with 200 millimeters fluctuation length and to hold around the angle be that 210 ° mode is placed on the outer surface of pipe.The diameter of this fastening metal line is 0.5 millimeter, is 6 millimeters seizings with line-spacing.Can also be clear that, compare its extensional with the bellows of not wrapping up in crust and reduced in essence.A bellows of evenly processing is born pressure by classification, a pressure all takes place after each level thus discharge.The property list of the pipe that quilt is so tested is shown on Fig. 3.Here be clear that the component of elasticity of this extension has each time much (the vertical curve part of curve 3).
This only is to be avoided the pipe or the prolongation of cable distortion at the component of its length direction and to improve tension intensity with this by the metal wire on the device.If these metal wires are littler with respect to the angle of pipe or cable long axis direction, this effect is just stronger.Must see that also these metal wires can not be parallel to the long axis of cable or pipe, otherwise metal wire will be stretched when swan-neck or cable.And the angle between these metal wires 2 and cable or the major axis of pipe 1 is bigger, and this component at long axis direction is just little so.This is between 15 to 25 ° at the cable or the optimum value of managing between 1 upper pulling force intensity and the bending property.
If there is not the fastening metal line, metal line layer 2 just can not conductance, because they do not have and cable or managing 1 outer surface links up.On metal line layer 2, fastening metal line 4 has just formed this connection to fastening metal line 4 with as far as possible little line-spacing.Moreover be exactly power when pricking metal wire 4, it plays a big part.Because the effect of this power produces metal line layer 2 and cable or manages the necessary vertical force of friction between 1.Act on the power of long axis direction for these, they are relevant with following factors:
1. the number of metal wire;
2. metal wire is to cable or the axial angle of pipe;
3. the diameter of metal wire;
4. the coefficient of friction between metal wire and cable or the pipe;
5. the coefficient of friction between fastening metal line and the crust metal line layer;
6. the pulling force of fastening metal line.
According to the application scenario difference, these factors must optimization process.
May also have other effect in some application scenario, when between the cable sheath that the outer surface of cable and metal wire form, the layer of metal band being arranged, copper preferably, this band and form one Metal line layer contact. Under this occasion, utilize this cable skin, just caused a shielded cable cortex simultaneously.
According to solution of the present invention just can success accomplishing: the mechanical property of a bellows or a cable improves in essence, and its bending property without limits substantially.
