Description

The invention relates to a fastening device for fastening a cable ring to a cable groove of a drying cylinder, comprising a tension applying clamping element. Accordingly, the invention relates to a cable ring and a clamping element. The invention also relates to a fastening method for fastening a cable ring to a cable groove of a drying cylinder. Moreover, the invention relates to a drying cylinder with a rope groove and arranged in the rope groove rope ring.

Such fastening devices and fastening methods for the cable rings of drying cylinders of paper machines are already known from the prior art. First, by means of machining, the rope grooves in the drying cylinders are prepared according to the shape of the rope rings to be picked up. Then, to achieve a dimensionally accurate recording of the cable rings, the open cable ring inserted into the respective cable groove and brought by means of a tension belt to the plant, where the cable ring is then cut to a defined gap and welded. This countersunk screws serve as anti-rotation, which connect the rope ring with the drying cylinder. In this implementation, the rope groove is designed such that it has a flat contact zone of less than 45 ° to the horizontal, which favor a rich support of the ring, so that the cable rings fit precisely in the rope groove.

After a further implementation, it is also known in the prior art to optically measure the rope groove shape in the drying cylinder, in order to manufacture the rope ring shape accordingly. Again, as in the first embodiment, the rope ring inserted into the rope groove, stretched by means of a tension belt and simultaneously brought by tapping with a plastic hammer to the full system, cut to defined gap and then welded. Compared to the first embodiment, no time-consuming and expensive processing of the rope groove of the drying cylinder is necessary.

In all cases, a self-tensioned rope ring in a rope groove of a drying cylinder can be provided by the tension straps and the welding.

It is an object of the present invention to provide a generic fastening device, a cable ring, a clamping element and a generic fastening method and a generic drying cylinder so that reliable generic generic rope ring can be positioned in the rope groove of a drying cylinder, the corresponding cable ring is then self-tensioned in the rope groove.

The object of the invention is achieved by a fastening method, a cable ring, a clamping element, a fastening device and a drying cylinder with the features of the independent claims. Further, possibly also independent thereof, advantageous embodiments can be found in the subclaims and the following description.

Thus, a fastening device for attaching a cable ring to a cable groove of a drying cylinder, comprising a tensioning tension element, characterized in that the clamping element comprises two mutually displaceable clamping blocks and that the fastening device is a two-component connection device with a rope-side first component and with a clamping bracket side second Component comprises, so that the cable ring is connectable by means of the two-component connection means with the clamping element.

The two clamping blocks of the clamping element of the fastening device are mutually displaceable, in order to be able to position these and, in particular, to be able to build up a tension on the cable ring for another.

The connecting device has two components, wherein the first component is on the cable-ring side and the second component is on the tension-arm side. By connecting the two components of the cable ring can be connected to the clamping element or with the two mutually displaceable clamping blocks of the clamping element.

Such a configuration makes it possible, by tightening the two clamping jaws, to tension the cable ring, so that it is possible to dispense with a tension belt which has to be wrapped around the cable ring in order to clamp it. This in turn, with a suitable arrangement of the jaws to each other - so they should not be arranged too close to each other - for example, enough free space for other activities that are necessary for attaching the rope ring grant. The latter in turn ensures to secure the rope ring reliable in the rope groove of a drying cylinder, the corresponding rope ring is then self-tensioned in the rope groove.

With the bracing of the two clamping blocks and the rope ring itself, because of the connection with the clamping blocks, part of a train applying clamping element.

Accordingly, a cable ring with a component of a two-component connecting device for connection to a clamping block of a clamping element on the one hand and a Clamping element with a clamping bracket with a component of a two-component connection device for connection to a cable ring on the other hand correspondingly advantageous to position the cable ring more reliable in the rope groove of a drying cylinder, the corresponding cable ring is then self-tensioned in the cable groove.

As a two-component connection device, any connection device can be used, which has a component which is providable on the cable ring, and a component which is providable on the clamping block, and which can be loaded with sufficiently large forces to give the cable ring its desired residual stress ,

For example, the two-component connector may include a tongue and groove connection, a pin-hole or pin-hole connection, a threaded stud connection, a hook-and-loop connection or other male and female connection, which can be trained sufficiently strong, be.

The one cable-ring-side first component or the component of the cable ring can preferably comprise a recess, preferably a hole. Such a recess or a hole can be easily provided in the cable ring and possibly even serve for other purposes.

Accordingly, the chuck-side second component or the component of the tensioning block can preferably comprise a bolt. Also, a bolt can be readily provided to a clamping bracket, where it may optionally be formed integrally with the clamping block. In particular, however, a corresponding bolt may be fastened to the clamping block as a separate assembly, for example by being mounted in a corresponding recess or in a corresponding hole.

A positive connection between the two components by means of a bolt-recess or bolt-hole connection can then be made easily between the cable ring and the respective clamping block by the bolt of the clamping block is spent in the recess or the hole of the cable ring.

In particular, the bolt may be a threaded bolt. This makes it possible to choose the bolt as a separate assembly and yet easy to attach to the clamping block, for example by there is provided a complementary thread. Preferably, the bolt are designed as a threaded bolt and the recess or the hole with a corresponding thread, so that a much more stable and stronger connection between the two components of the connecting device made and the bolt can be secured to the arrangement of cable ring and clamping bracket.

It is understood that if necessary bolt and recess can also be interchanged with each other, so that the recess on the respective clamping bracket and the bolt are attached to the cable ring.

In that regard, one of the two components, a recess, preferably a hole, and the other of the two components comprise a corresponding bolt. In this way, a positive connection of the two components can be achieved so that the cable ring can be reliably positioned. Preferably, as explained above, the chuck-side component of the bolt and the rope-ring-side component on the hole.

In particular, it is advantageous if the recess or the hole and the bolt each comprise corresponding threads. This not only a positive connection but even a screwed connection of the two components of the connecting device is possible. Such a screw connection can ensure a still reliable positioning of the cable ring in the cable groove and can largely prevent any offset, in particular perpendicular to the hole or bolt axis, between clamping bracket and cable ring or bolt and hole due to the fixed connection.

In particular, the two-component connection device has the advantage of a more reliable positioning of the cable ring.

Preferably, at least one two-component connecting device is provided per clamping block, so that both clamping blocks can be correspondingly connected to the cable ring. In particular, the two two-component connecting devices can be designed to be identical, so that it does not matter which of the clamping blocks at which point of the cable ring is connected to the cable ring.

In order to clamp the two ends of a rope ring, so that they can then be suitably cut to length and connected to each other, a tension bracket is advantageous for each end of the rope ring.

Insofar as then each clamping block should be connectable to the corresponding cable ring, it is advantageous if each of the two clamping blocks a two-component connection device having. It is then advantageous to design the two connecting devices identically, since the connecting device can thus be used much more flexibly, because, for example, the arrangement of the clamping blocks or connecting device is not relevant for a reliable implementation. For example, each bolt of the clamping blocks can be connected to each recess or with any hole of the cable ring. A different design of the connecting device could have the consequence that for each connection device differently shaped cable rings or holes can be connected only to a very specific clamp or only with specific bolts, which may require further manipulation before each attachment process, for example Correction of the orientation or positioning of the clamping element or the cable ring condition and thus can lower the reliability.

Preferably, the clamping blocks are connected to each other by means of a clamping bracket. In order to tension the cable-ring ends which are fastened to the clamping blocks against one another, a clamping bracket can be arranged between the two clamping blocks, which exerts forces on the clamping blocks in the clamping direction of the cable-ring.

The use of such a tension bow has the advantage that the shape of the tension bow can be chosen such that it allows an unobstructed or largely unhindered access to cut to length of the cable ring ends and for the production of the joint weld. In addition, no the rope ring spanning strap is necessary, which hinders the tapping of the ring. It is understood that instead of the tensioning bow and other clamping means for connecting the two clamping blocks for applying a voltage, such as provided only between the clamping blocks tension straps or clamping screws can be used, which should not or only slightly impede the welding process.

The clamps can also have recordings for the clamping bracket, so that the clamping bracket engages reliably in the clamping blocks and no offset of the clamping bracket is allowed during clamping. Also, such recordings can ensure a reliable clamping, as can take place on the recordings a controlled power transmission from the clamping bracket in the vice. In this case, the recording can be performed in various ways, for example, by the clamping block continuously or only as a recess.

It is also advantageous if the clamping element comprises a clamping nut. Preferably, the clamping nut can be combined with a continuously formed or captive but movable recording of the clamping bracket in one of the clamping blocks, so that the clamping nut can sit on the protruding from the exception of the clamping bracket clamping bracket. The clamping bracket can then reach up to a second clamping bracket and there by means of a displaceable by the clamping nut clamping device clamping the second clamping bracket to the first clamping bracket pulling.

By turning the clamping nut, the chucks move towards each other. The clamping nut presses in the tensioned state against the clamping block. The clamping nut is used to adjust the voltage, whereby the clamping force can be safely inserted directly into the cable ring. By means of the clamping nut, a voltage is generated in the simplest and most cost-effective manner and the clamping forces are maintained. It is understood that other clamping force introducing means may be used, which may be more complex and usually more expensive.

Furthermore, the clamping element may additionally comprise a separate hold-down to press the cable ring outside of the clamping blocks in the rope groove. In this way it can be prevented that the cable ring is possibly dug out of the rope groove, which may possibly be done by the tensile force on the clamping bracket, which possibly exerts moments on the cable ring ends on the clamping blocks.

Accordingly, it is advantageous if the hold-down in each case in the vicinity or on the side of a tensioning block on the rope ring hold down. This applies in particular to the side which faces away from the tension bow or the ends of the cable ring to be connected.

In addition, the fastening device may comprise a jacking screw. The forcing screw serves to lift a rope ring end defined. This allows a simpler processing of Seilringendes, in particular to be able to cut to length.

In order to realize an optimum gap of, for example, 1.5 mm for the joint weld seam, the rings made with excess length are carefully fitted before welding. With the help of such a jacking screw, the supernatant can be shortened accurately. If necessary, the process can be repeated several times by lowering the cut end of the rope ring, measuring the gap and lifting the rope rings again for a repeated cut. The jacking screw thus enables a reliable fit with the simplest possible design.

Preferably, the jacking screw is inserted into a threaded hole of the cable ring, which is located in the vicinity of the corresponding Seilringendes so that the jacking screw only there screwed and needs to be screwed in the direction of the bottom of the rope groove to lift the Seilringende.

The thread can in particular correspond to the above-explained thread of the connecting device, so that here little operational effort is to operate to provide this additional thread.

Thus, a fastening method for attaching a cable ring to a cable groove of a drying cylinder can be characterized in that first the cable ring connected to at least one recess, preferably with a hole, at least one radially outwardly arranged at the bottom of the cable groove support leg and so a parallel directed to the cross-section positive contact between the cable ring in the rope groove is made and then by means of a clamping element the two cable ends are braced against each other to more reliable position a cable ring in the rope groove of a drying cylinder, the corresponding cable ring is then self-tensioned in the cable groove.

It is understood that in particular a plurality of such support feet and in particular also corresponding recesses or holes can be provided distributed around the circumference, wherein the distance between the support feet is selected such that the cable ring in the areas between meet the forces acting on him rope forces safely and permanently can.

Possibly. can, in particular in the region of the interface between the cable ring ends, which are welded together or should be welded, the density of the support legs and possibly the recesses or holes can be increased because there, u.a. because of the notch effect, the allowable bending stresses should be the lowest.

Preferably, the support feet are attached to the cable ring. This can be done, for example, by being welded thereto or shrunk into it, for example into the recesses or holes, which, however, hinders subsequent corrections. In particular, the connection can be made via a thread, wherein preferably the recesses or holes can have an internal thread and the support feet can have an external thread, which is correspondingly easy to implement.

In particular, the support foot or the support feet can be designed as a bolt with thread or as a threaded pin, so that they can be provided particularly easily.

It is understood that particularly advantageously the recesses or holes for the support feet preferably correspond to the recesses or holes for the jacking screw and / or for the two-component connecting devices, so that corresponding counterparts, such as screws, bolts or pins can be used. This allows, for example, when the two-component connecting devices are opened after closing the cable ring, or to use the remaining components of the two-component connecting devices or the recesses or holes for the support feet after a correct cutting of the cable ends, so that in particular in the region of the weld Density of Abstützfüße can be relatively high in a structurally simple way.

Preferably, the support feet are based only on the bottom of the rope groove, so that the holes or recesses of the rope ring does not necessarily have to be aligned with any arrangements on the rope groove, such as with holes or support legs mounted there. Rather, then, the position of the support legs along the rope groove adapted and possibly even slightly corrected, which is particularly advantageous during tensioning.

Preferably, therefore, initially a positive connection between the cable ring and the rope groove can be made and the cable ring can thus be reliably positioned in the cable groove.

The Seilringenden are, as already indicated above, braced against each other after positioning by means of a clamping element. For this purpose, the positive connection of the cable ring for Seilringnut is very advantageous because the cable ends can be clamped directly against each other without a risk of dislocations of the cable ring is in position within the cable groove or so that this risk can be minimized. In this way, a direct introduction of clamping force in the cable ring can be achieved and a reliable fastening of the cable ring can be achieved at the Seilringnut.

The clamping force is preferably introduced into the cable ring by means of a clamping nut, in particular with the clamping nut already explained above. This allows a relatively simple and well-dosed application of the clamping forces, in particular also relatively high clamping forces.

Preferably, as already explained above, the cable ring by means of one or more hold-down, which act in particular close to the clamping blocks at the side facing away from the respective cable ring end, pressed into the cable groove. Naturally, the latter is preferably done outside of the clamping block, since there is no room for a preparation of the blank holder.

As also explained above, the Seilringüberstand or the end of the rope ring can be shortened accurately in the clamped state, including in particular the jacking screw can be used.

Preferably, the cable ring is also knocked out at the same time during clamping. By tapping the clamping process is supported. Since by the method described above and the devices described above, no around the cable ring circumferential strap is more necessary, the tapping of the ring is not hindered. It is advantageous if the knocking takes place by means of a plastic hammer, since this provides an optimal force and also does not damage the cable ring or other components of the fastening device.

It is understood that at least parts of the clamping element after attaching the cable ring to the Seilringnut can be removed again. For example, it is no longer necessary to maintain the tension between the cable ring ends by means of the tensioning element after fastening and especially after welding the cable ring ends, so that, for example, the clamping bracket can be removed again. As a result, unnecessary parts can be removed and possibly reused. In particular, however, parts of the two-component connecting device, especially the rope-ring-side component thereof, may remain on the cable ring or on the drying cylinder.

Thus, a drying cylinder with a rope groove and arranged in the rope groove rope ring can be characterized in that in the rope groove at least one support foot is directed radially outwards, and more reliable a rope ring can be positioned in the rope groove of a drying cylinder, the corresponding rope ring then it is strained in the rope groove.

In order to carry out the above-described fastening method with fastening devices also described above on a drying cylinder, the drying cylinder described above preferably has in its rope groove at least one support leg, which is arranged radially outwardly.

As also described in the fastening method or in the fastening device, the cable ring can have recesses or holes, which can also be positively connected to the rope groove of the drying cylinder.

Preferably, the or the support feet are based only on the rope groove, preferably at the Seilrillengrund from. In this way it can be ensured that, during tensioning, the cable ring can follow or follow a displacement caused by the tensioning.

In the area of the support feet of the rope ring can not be naturally pressed deeper into the rope groove. The pitch of the support legs is therefore preferably selected so that the cable ring in the areas between the acting rope forces can safely and permanently endure. By several support feet of course the position of the cable ring is determined in the rope groove, so that the cable ring is positioned in a certain position, preferably centrally, in the cable groove and remains there, while only one support foot there is a risk that the cable ring around this support leg twisted around.

The support legs can preferably be designed as threaded pins, which are employed after the final assembly of the cable ring on the rope groove base, welded to the cable ring and / or can be ground smoothed or are. The latter measures may also apply to the use of other types of support feet.

By such a method, no processing of the rope grooves of the drying cylinder is necessary, as is the case in the prior art, so that with the least possible effort a corresponding rope groove can be provided.

It is understood that the features of the solutions described above or in the claims can optionally also be combined in order to implement the advantages in a cumulative manner.

• 6 a second fastening device in a schematic side view.

The embodiment according to 1 to 5 has a fastening device 1 with a clamping element 4 and two connecting devices 6 on. In the present embodiment, the tensioning element comprises 4 two vice's 5 , which have a clamping bracket 8th connected to each other.

Each of the vice 5 is in each case by means of one of the connecting devices 6 with a rope ring 2 connected.

By means of a clamping nut 10 , which on the clamping bracket 8th are fixed, clamping forces can be applied.

The chucks 5 also have shots 9 on, in which the clamping bracket 8th each in the clamping blocks 5 is positioned. Here is the clamp 8th in one of the shots 9 firmly but rotatably mounted, so that he firm but movable with the associated clamping block 5 connected while recording 9 the other vice 5 essentially forms a plant against which the clamping nut 10 can be stretched.

That in the 6 illustrated embodiment corresponds to the embodiment according to 1 to 5 , where instead of the tension bracket 8th a threaded rod 20 in parallel to the circumferential direction aligned shots 9 the vice 5 is arranged and the two clamping nuts 10 , which are each on the other Spannbock 5 opposite side on the threaded rod 20 are arranged, can be braced.

Like that 1 . 5 and 6 to take, are each Seilringenden 21 with each other by means of a weld 22 be welded.

The tensioning element 4 is always with the rope ring 2 connected.

The present embodiments include a connector 6 with a rope-ring-side first component 17 and with a gimbal-side second component 18 , whereby each Spannbock 5 two two-component connecting devices 6 are provided.

The tensioner-side second component 18 includes a bolt 19 while the rope-ring-side first component 17 holes 7 includes, so that the first and the second component 17 . 18 the connection device 6 via a bolt-hole connection in the direction of the clamping force or in the circumferential direction around the cable ring 2 can be positively connected with each other.

In concrete terms, both are the bolt 19 as well as the holes 7 the one end of the rope 21 remote connection device 6 threaded so that the chucks 5 reliable with the rope ring 2 can be connected. This connection is sufficient, so the bolts 19 each of the Seilringenden 21 facing connection device 6 without thread in the holes 7 can be used, where appropriate, the associated holes 7 have a thread or can be subsequently provided with a thread, if this makes sense, for example, for the subsequent attachment of a support foot 14 makes sense.

As in 3 represented, is or is the rope ring 2 in a rope groove 13 a drying cylinder 3 , which is intended for a paper machine, inserted. The rope groove 13 is designed in this embodiment such that designed as threaded pins support feet 14 at the bottom of the rope groove 13 are arranged directed radially outward. These are also in holes 7 arranged with a thread.

The density of the arrangement of the support feet 14 depends on the expected load on the rope ring 2 off, with the holes 7 , as the rope-ring-side first component 17 serve, and in their diameters and their threads those for the support feet 14 so that after the chucks are removed, also in these holes 7 possibly support feet 14 can be used.

These support feet 14 also serve the reliable positioning of the rope ring 2 in or in the rope groove 13 , as a positive contact of the rope ring 2 to the bottom of the rope groove 13 allows and while stationary as possible position of the cable ring 2 in the rope groove 13 can be guaranteed.

As in 4 shown, when the rope ring 2 by means of the tension element 4 in the rope groove 13 is curious, a hold-down 11 used to the rope ring 2 outside the chipbuckles 5 in the rope groove 13 to press and position it during the tensioning process.

5 shows the fastening device 1 in the tensioned state, with a rope ring overhang 15 was created by the clamping process, which by means of a jacking screw 12 is raised so that the cable end 21 or the rope ring protrusion 15 can be shortened accurately. Possibly. can the rope ring end 21 of the rope ring 2 several times again by means of the jacking screw 12 be lowered to check the fit and if necessary to carry out repairs.

Also the jacking screw 12 sits in a hole 7 with thread, which the other holes 7 corresponds, so that here also possibly a support foot 14 can be arranged.

During tensioning, the rope ring can 2 by means of a plastic hammer 16 be knocked off, so that any tension can be solved. Because of the support feet 14 only at the bottom of the rope groove 13 These can support any movement of the rope ring 2 follow in the circumferential direction. On the other hand, the support feet secure 14 the rope ring 2 in the axial direction of the drying cylinder 3 and keep it in the rope groove, both during cocking and rapping and then in use 13 positioned axially and radially suitably.

Corresponds to the tension in the rope ring 2 the desired tension and are the Seilringenden 21 of the rope ring 2 cut to a suitable extent, so they can each other through the weld 22 be welded. The rope ring 2 is then under residual stress in the rope groove 13 curious; excited.

Then the connecting devices can 6 solved and the Spannböcke 5 be removed. Possibly. become the support feet 14 still in her employment with respect to the reason of the rope groove 13 suitably employed. Then these are with the rope ring 2 welded and stamped with this sanded.
