Mounting member and its manufacturing method

Detailed description of the invention

The present invention is formed in one spiral winding direction, wherein the at least one attachment branch consists of an attachment line in which the wire or rope-shaped body can be helically engaged and can be frictionally limited to any relative movement in the longitudinal direction. It relates to an excitation mounting member and in particular to a terminating or suspension mechanism for a wire or rope shaped body, in particular for ropes or cables of aerial transmission lines.

The present invention also relates to a method for manufacturing a mounting member comprising at least one attachment branch formed in a spiral winding direction and having an attachment line.

This type of mounting member exerts an excellent effect in attaching aerial transmission lines to aerial line pillars or buildings. For the assembly of this mounting member the screws are screwed in a straight line to a part of the aerial line, which is in the rotating attachment branch and for example the mounting piece of the mounting member is fixed to the desired mounting point.

This type of mounting member, for example already known in the German Federal Republic of the Specifications DE-OS 1 590 666, DE-PS 1 590 686, DE-OS 21 12 237 or DE-PS 29 15 698, is for example the Federal Republic of Germany. It is made to consist of a plurality of metal wires elastically deformed in a suitable mounting member manufacturing apparatus as known from specification DE-PS 1 510 128 or US specification US-PS 4, 015, 073. The metal wires are either parallel to each other or twisted together in the mounting piece area, whereas in the attachment branch preferably they are parallel to each other.

The problem with these already known mounting members is that they must be made of relatively rigid metal wires in order to obtain a sufficiently strong contact with the body, such as a wire or rope, which is difficult to manipulate and assemble, especially when attached to transmission line pillars. It can be found that the mounting member has a poor vibration damping property and thus additionally provides a special vibration damping mechanism.

It is therefore an object of the present invention to provide the above-mentioned mounting member which can be easily manufactured, operated and easy to assemble.

For a mounting member of the kind mentioned above the object can be achieved in accordance with the properties of the invention consisting of at least one fiber strand composed of long fibers which are twisted together with an attachment line and penetrated into a matrix of synthetic material.

The solution according to the invention makes it possible to produce a mounting member in which the matrix of fiber-reinforced synthetic material exhibits a high longitudinal strength on the one hand and on the other hand can be heavily loaded, but secondly, such a mounting. This has the great advantage of exhibiting low transverse strength which makes the member easy to handle, especially during assembly.

It is noteworthy that the mounting member according to the invention comprising fiber strands composed of long fibers that are twisted and penetrated into a mattress of synthetic material is particularly flexible while having high resistance to tension. The high tension can thus be transferred on the one hand and on the other hand the flexibility allows the same mounting member to be used for larger tolerances of wire or rope shaped bodies.

Furthermore, the mounting members of the fiber strands composed of long fibers twisted together and penetrated into the matrix of the synthetic material exhibit good damping properties, so that vibrations of the wire or rope-shaped body can be effectively damped, for example by means of metal wire This has the advantage that the damping elements that have been required for the mounting mounting components are no longer needed.

Finally, the mounting member made of the fiber strand according to the present invention has the advantage that the component of the fiber reinforced synthetic material has a high fatigue strength and thereby shows a long life.

In addition, the production of fiber strands of long fibers that are twisted together and penetrated into a matrix of synthetic material reduces the strength of the fiber strands as they are radially separated from their centers, but at the same time the more they are separated from the centers of the fiber strands For example, metal wires can be constructed to increase the bending tension, which is important for the effect of clamping fiber strands around larger wire or rope shaped bodies.

The above-mentioned content is particularly advantageous for the mounting mechanism according to the invention when the twisting direction of the long fibers of the fiber strand in the direction of rotation is opposite to the winding direction of the attachment line.

The advantage of this configuration is that due to this progression in the twisting direction the fiber strands tend to twist under tensile load in the above direction, ie in the same direction as the winding direction of the attachment line, thereby tending to lie closer to this wire or rope-shaped body. This can be seen in particular in that it increases the bonding force of the mounting member according to the present invention.

In the simplest case the attachment line can be made of fiber strands. However, it is even more advantageous if the attachment lines are woven into multiple adjacent fiber strands. Alternatively, the fiber strands themselves may be adjacent to each other, as may be the case in the adjacently located wires of the prior art, and may be independent of each other only because of the outer shape of each fiber strand.

In another particularly preferred embodiment, the fiber strands form a composite fiber cord, whereby one composite fiber cord or a plurality can form an attachment line.

There has been no detailed description of the fiber strand configuration until now. Thus, for example, one could imagine producing fiber strands from carbon fibers. However, since they are electrically conductors, it has been envisioned that the fiber strands are preferably composed of fibers of an electrical insulator. It is of great advantage that current-carrying conductors can be fixed directly to this type of mounting member or that capacitive coupling to fibers of the fiber strand for partial discharge no longer appears in the case of current-carrying wires or rope-like bodies.

Preferably the fibers may be glass fibers, alternatively aramid fibers or polyethylene fibers.

Likewise, no discussion of the matrix of synthetic material surrounding the fibers is made in the previous specific examples. Therefore, in a preferred embodiment of the present invention, the matrix of the synthetic material is composed of a thermosetting plastic.

In another preferred embodiment the matrix of synthetic material is of thermoplastics. In the previous specific examples the fibers had to be long fibers to ensure sufficient tensile load of the fiber strands, but in another preferred specific embodiment of the present invention the fibers are continuous.

As regards the mounting member, in the specific practice mentioned so far it has been defined that the mounting member should consist of only one attachment line. Thus, for example, a mounting member consisting of two attachment lines may be conceived for connecting two wire- or rope-shaped bodies. However, if the attachment line in contact with the attachment branch is formed of a mounting piece such that the mounting piece becomes a loop, it would be particularly convenient for the mounting of a wire or rope body.

Moreover, until now it has only been specified that the mounting member should have one attachment branch. However, it is particularly desirable if the mounting member consists of two attachment branches to obtain a capacity for carrying a large load.

The two attachment branches can thereby extend in different directions. However, in a particularly preferred embodiment of the mounting member according to the invention the attachment branches are preferably wound around each other in such a way that the attachment branches are wrapped around each other in the same place so that the attachment branches are preferably wound around each other and thus an improved fixing effect is obtained.

In the previous specific embodiment, no specific reference was made to the shape and arrangement of the attachment branches of the mounting member prior to its installation. Thus, in a preferred specific embodiment of the present invention, the attachment branch is spirally wound before assembly, that is to say arranged in a relative position, such as a position to be taken later after assembly.

In this case, the attachment branches must be loosened together before being assembled and then rewound around the wire or rope body. In addition, in contrast to the existing mounting member made of the metal wire of the present invention, the mounting mechanisms of the present invention are separated from each other and do not have attachment branches that need to be tied together or require a large space. This is especially true in terms of the amount of space required.

It is easy to think about the features of the specific embodiments described so far and the construction of the fiber strand itself. However, it would be particularly advantageous if sheathed the fiber strands. This type of sheath basically has the great advantage that the delicate compounds of the matrix of long fibers and synthetic materials are further protected.

It would therefore be particularly desirable if the sheath was configured to additionally absorb ultraviolet rays to protect the fiber strands against corrosion or weather and in particular to prevent any damage caused by ultraviolet rays to the compounds of the matrix of long fibers and synthetic materials. will be.

Another advantage of the shell is that it can avoid any contamination of the fiber strands by virtue of the covering. In addition to or supplementing the above features of the present invention, the shell forms an insert for adjacent fiber strands. This serves to prevent the individual fiber strands from sticking together, for example when using thermoset plastics, or to prevent contamination of the mold and its auxiliary devices.

In contrast to the specific embodiment of the shell mentioned or in another embodiment of the shell there is arranged on the inner surface of the fiber strand forming the attachment line to improve the friction between the wire- or rope-shaped body and the attachment line. , A carrier of the coating to increase friction.

At the same time, the envelope can be formed in the most variety of ways. In one preferred specific embodiment of the shell it is a coating of fiber strands. Coatings of this type can be prepared in a single step or multistage powder synthetic resin process or injection process using suitable materials, for example synthetic materials, in particular thermoplastics.

Unlike this, it is conceivable that the shell is formed by a film surrounding the strand. The film can thus be fixed in the most versatile way, for example the film can be fixed to the fiber strands by a welding process. For this purpose, for example, it is wrapped or laid around the fiber strands and bonded to the fiber strands.

Another preferred form is that the sheath encloses a plurality of fiber strands. In order to protect all the fiber strands when the sheath is damaged, it is preferable that the sheath faces the fiber strands, completely enclosing each fiber strand in a sealed manner so that each fiber strand is sealed with its own sheath. You must lose. This can be done by placing the foil around the fiber strands in a suitable manner and welding or injection molding a plurality of fiber strands.

It is particularly preferred when the sheath encloses multiple fiber strands simultaneously, especially when the sheath joins the fiber strands into composite fiber strands. In this case, each fiber strand does not need to be handled separately during the manufacturing of the mounting member, but rather a single composite synthetic fiber cord can be handled as a whole.

In addition, the attachment line should preferably be composed of a composite cord so that the attachment line can be more easily handled even when the spiral-shaped one is applied to the wire or rope-shaped body. It is particularly desirable for the skin to keep the fiber strands at a distance from each other so that the areas of the skin located between the fiber strands can serve to prevent wrinkle formation when the attachment line is spirally wound.

There has been no detailed description of an attachment line forming an attachment branch until now. Thus in one preferred specific embodiment the attachment line is adapted to have a coating that increases friction on the inner surface. Such coatings may be applied by polishing the attachment lines and by applying a corrugated layer, for example, a coating that increases friction using suitable sugar materials for the matrix of sticky or synthetic materials.

However, as already described, it may be envisioned that the coating that increases friction is retained by the sheath or that the coating is secured to the fiber strand by the sheath. In this and another preferred method, it is conceivable that the attachment line represents an inner surface formed to increase friction. For this purpose it is preferred to make suitable grooves in the inner surface of the attachment line.

The mounting member according to the invention can be configured such that it can be installed in a wire or rope shaped body. Alternatively, however, the mounting member according to the invention may also be configured to be mounted on a wire or rope shaped body by means of an intermediate piece which increases friction, for example a sheath which increases friction.

In a particularly convenient way it is conceivable that the clamping wedges for receiving the wire- or rope-shaped body can be gripped by the attachment line so that the clamping wedges form an intermediate piece.

Thereby, the clamping wedge may preferably be configured to consist of two wedge halves that can be secured to each other. It is also an object of the invention in the above mentioned kind of method that the long fibers are penetrated into the matrix of the synthetic material and twisted together in one twisting direction, while the matrix of the synthetic material is plastically deformed while at least one fiber strand The attached attachment line is formed in a spiral shape in the winding direction and then the synthetic matrix can be achieved by the present invention in which it is no longer plastically deformable or placed in a rigid form.

The mounting member produced according to this type of method already has the advantages described above in connection with the mounting member itself. It would also be particularly desirable if the direction of rotation of the direction was opposite to the direction of rotation of the winding line of the attachment line, which would result in a better clamping effect of the mounting member according to the invention.

If the attachment line is made of a plurality of fiber strands connected to each other, the processing of each fiber strand is unnecessary during the manufacturing process of the attachment line, so that the speed of production can be increased specially while the attachment line is wound. Particularly preferred for production.

Regarding the manufacture of the attachment branches, it has proved to be particularly desirable if the attachment branches are spirally wound on the core so that the matrix of synthetic material associated with the attachment branches is plastically deformable.

For the reasons already mentioned in connection with the description of the mounting member, it has proved desirable to provide a sheath for the fiber strand. It is thus conceivable to provide in particular a fiber strand with a plastically deformable state, in particular a non-solidified state, of a matrix of synthetic material. In the case of thermoset plastics this configuration allows for immediate processing of the fiber strands without the need to be careful not to solidify the matrix of the synthetic material. However, it is particularly desirable if the shell is a thermoset resin so that the fiber strands can be prevented from sticking during further processing of the attachment line. This is particularly required to provide an outer sheath for the fiber strands, especially immediately after manufacture of the fiber strands themselves, before spiraling the attachment lines.

Fiber strands can thus be produced by coating, whereby the coating can be coated, for example, with a varnished layer or with a sprayed layer. In contrast to this, it is conceivable that the fiber strands are wrapped in a film so that the foil is preferably bonded.

It is conceivable to provide a friction increasing layer on the inner surface of the attachment line to increase the friction between the attachment line and the wire or rope shaped body. This friction increasing layer is preferably applied to the fiber strands or their shells before or after the production of the attachment lines.

Alternatively, it is conceivable that the attachment line is formed such that the friction of the inner surface is increased, that is, the attachment line has a surface structure which increases the friction between the attachment line and the wire or rope-shaped body. Preferably the form of increasing friction of the inner surface can be obtained by winding the attachment line on the core with the negative mold increasing the friction.

The manufacture of the mounting member according to the invention is carried out when the fiber strand is in the form of a flat cord, in particular in the form of a flat cord which forms a belt with side closures, in the form of a terminal spiral where the negative mold for the loop is arranged on both sides of the center. Particularly preferred. It is furthermore possible to use dead eyes arranged on both sides of the center as negative molds for the loop.

Detailed description of the invention

A specific embodiment of the mounting member according to the invention is the terminating helical portion shown in FIG. 1, in which the two helical branches 14, 16 used as attachment branches are shown in FIGS. It has a loop 12 formed as shown in FIG. 2.

These helical branches 14, 16 are each formed by attachment lines 22, which are such as to rotate around the axis 20 in one helical winding direction 18. As shown in FIG. 2, a plurality of fiber strands 24 are included. The axes 20 of the attachment lines 22 of each helical branch 14, 16 are coincident.

As shown in FIG. 3, this type of terminating spiral 10 is used to hold the support cable 26 of the air transport line 28 or directly support the air transport line 28. Two spiral branches 14, 16 are wound around the area 30 of the support cable 26 so as to be located in the support cable 26 around the surface and in the longitudinal direction 32 of the support cable 26. Due to the tensile stress effect, the helical branches are pulled tightly to support the support cable 26 such that the seal cannot move in the direction 32. In doing so, for example, the loop 12 is suspended around a tightly anchored anchor 33 and preferably placed around a dead eye that prevents wear of the loop 12.

As shown in FIG. 4, each fiber strand 24 comprises a number of elongated fibers 40. However, long fibers 40 that are twisted together and embedded in a matrix of synthetic material 42 are continuous fibers.

Preferably electrically nonconductive fibers, in particular glass fibers or aramid fibers, are used for the long fibers 40.

As shown in FIG. 5, the twist angle j is represented with respect to the longitudinal direction 44 of the fiber strand 24 made from the twisted long fibers 40, and the angle varies with respect to the radius r, The twist angle j increases linearly from r = 0 to r = r _{max with} the radius r from the center of the fiber strand 24.

As shown in FIG. 6, the modulus of elastic Ex of this type of fiber strand 24 is somewhat different from this. The modulus of elasticity decreases as the radius r increases from the center of the fiber strand 24 up to the maximum radius r _max , which indicates that the fiber has a larger twist angle that twists as the radius r increases. This is related to the fact that the fiber strands become more elastic in this area.

Thus, as shown in FIG. 7, as the radius r of the fiber strands 24 increases, for example, by means of the fiber strands 24 composed of glass fibers embedded in a matrix of synthetic material 42, for example. When the tensile stress is applied (Fig. 7a), the tension s decreases as the radius r increases up to the maximum radius r _max . This is significantly different from metal strands as can be seen from the known art as shown in FIG. 7B. Here the distribution of tension s over radius r is constant.

Due to the elastic modulus Ex varying with the radius r, it shows the distribution of the bending stress b with respect to the radius r of the fiber strand 24, as shown in FIG. It is more flat compared to the distribution of bending stress (b) for the metal strand as shown.

From this fact it can be seen that the twisted fiber strands 24 according to the invention are flexible and furthermore have low tensile stiffness occurring on their outer surface. Together these two elements increase the clamping effect of the attachment line 22 produced from this type of fiber strand 24.

Furthermore, the twisted fiber strands 24 according to the invention are also characterized in that the outer twist angle j1 changes when there is a tensile stress therein, i.e., the tensile stressed fiber strands 24 (as shown in FIG. 9). The twist angle j2 of the outer fiber of the outer fiber shown in FIG. 1 is smaller than the twist angle j1 of the outer fiber of the tensile stressed state (shown in solid line). From this, we can additionally know: That is, since the fiber strands 24 tend not to be twisted in the tensile stressed state, the fiber strands 24 are twisted over the angle V in the non-tensile stressed state.

If the attachment line 22 is constructed from this type of fiber strand 24 in such a way that its winding direction 18 is opposite to the twisting direction 46 as shown in FIG. When present, the rotation v is effective in the winding direction 18, which can be accurately recognized from FIGS. 10 and 11 (tension stressed: shown in dashed lines, unstressed: diagonally More closely match the contour of the support cable 26.

The fiber strand 24 according to the first specific embodiment is manufactured in the simplest case as shown in FIG. 12 and the required number of long or continuous fibers 40 fails 50 of the failed carrier 52. At the same time each fiber is fed through a permeation device 54 which is permeated with the material of the synthetic matrix 42.

These fibers are penetrated by the matrix of synthetic material 42 and then fed to a nozzle 56 which combines each of the fibers 40 and the matrix of synthetic material 42 into fiber strands. The failing carrier 52 rotates around the axis 58 to achieve the required twisting of the fibers 40 in the fiber strands 24.

The fiber strands 24, for example, as shown in FIG. 12, the rotation speed of the strand drum and the failure carrier 52 will determine the angle of twist. The fiber strands 24 produced in this way can now be processed, for example, to spirally wind a plurality of adjacently positioned fiber strands to form the attachment line 22, thereby In order to be wound, the composite matrix must be uncured or laid plastically deformable. The device according to the invention for the production of the attachment line 22 according to the invention will be described in detail below.

Fiber strand 24 may also be made of sheathed fiber strand 124. Instead of being wound by the strand drum 60 after the fiber strand 24 has passed through the nozzle 56, as shown in FIG. 13, the fiber strand therein is coated with the powder resin. Passing through the coating station 62 can be primarily carried out so that the powder resin is sprayed onto the fiber strands 24 in the coating station 62 or applied using a fluid bed bed process. The fiber strands 24 provided with the powder resin layer 126 in this manner after the coating station 62 are formed with a uniform varnish layer 128 in which the powder resin layer 126 is dissolved to surround the fiber strands 24. Is passed through a fusing station 64.

Coated fiber strand 124, which is then composed of varnish layer 128 and fiber strand 24, is wound by strand drum 60.

A second method of manufacturing the encased fiber strand 224 is shown in FIG. 14, in which case the fiber strand 24 emerging from the nozzle 56 is a film tape of synthetic material 228, for example. For example, coated with a polyester shrink film. The film tape of this synthetic material 228 is supplied to the film welding apparatus 66. In the film welding apparatus 66, a film tape of the synthetic material 228 is covered around the fiber strands 24, and, for example, on the fusion suture 230 as shown in FIG. 15 on one side. By welding to the fiber strand 24 as closely as possible. This is followed by the fiber strand 224, which is encased in this manner by the film tape 228, around the strand drum 60.

The second specific embodiment of the overlaid fiber strand 224 shown in FIG. 14 differs from the nozzle 56 of the third specific embodiment of the overlaid fiber strand 324 followed by a film of synthetic material 228. The tape is wound continuously in a spiral around the fiber strand 24 and in the winding device 68 the film tape of the synthetic material 228 is wound around a failure 70 that rotates itself around the longitudinal axis 44 of the fiber strand. . The film tape of synthetic material 228 is thus preferably wound in a manner that covers around the fiber strands 24 and then in particular in a manner followed by heat treatment.

A fourth specific embodiment of jacketed fiber strand 424 is shown in FIG. 17 where fiber strand 24 from nozzle 56 is melted synthetic material, for example polyethylene, into extruder 74. By the injection molding machine 72 supplied thereto. This fiber strand is not just one individual fiber strand 24 that is injection molded in the injection molding machine 72 but a plurality of adjacent fiber strands 24 are injection molded simultaneously where each fiber strand 24 is coated Surrounded by 428 and each coating 428 is in turn connected by web 430 such that sheathed fiber strand 424 forms synthetic fiber cord 432 as shown in FIG. 18. Where a plurality of sheathed fiber strands 424 are connected to each other at a distance defined by the web 430 between each coating 428.

In the fifth specific embodiment of the encased fiber strand 524 as shown in FIG. 19, the plurality of fiber strands 24 are also fed to the fusion station 76 after passing through the nozzles 56 provided to them. do. The station is further supplied with a top film tape 528a of synthetic material and a bottom film tape 528b of synthetic material as also shown in FIG.

The two film tapes 528a, 528b of synthetic material in the fusion station 76 are provided with fusion sutures 526 as close as possible to the fiber strands 24 on each side of the fiber strands 24, so that each fiber strand 24 is melted between the upper film tape 528a of the synthetic material and the lower film tape 528b of the synthetic material. Once again the two regions of film tape 528a, 528b of synthetic material located between each fiber strand 24 thus form a web that keeps each fiber strand 24 at a fixed distance from each other. Fiber strands 24 also form synthetic fiber cords 532 due to the sheath formed by synthetic film tapes 528a and 528b bonded together.

In a sixth specific embodiment of the encased fiber strand 624 according to the present invention, a plurality of fiber strands 24 are supplied to the packaging station 78 after passing through the provided nozzles 56, where the fiber strands 24 is alternately supplied to the packaging stations of the two planes 80 and 82. Moreover, the interstitial film 626 is supplied to the packaging station 78 as well as the upper film tape 628a of synthetic material and the lower film tape 628b of synthetic material. In the packaging station 78, the embedding film 626 is laid in a corrugated manner by gathering two planes 80, 82 between the continuous fiber strands 24, in addition to the top of the synthetic material. Film tape 628a and a lower film tape of synthetic material are also placed above and below adjacent fiber strands 24, respectively. Moreover, the film tapes 628a and 628b of synthetic material have substantially adjacent fiber strands 24 that are fused to each other and to the embedding film 626 and are only separated from one another by the embedding film 626. Synthetic fiber cord 632 is also formed.

Of course, in this synthetic fiber cord, the fiber strands 24 are also wrapped, each of which is entirely made of film tapes 628a and 628b and the embedding film 626 of synthetic material, as shown in FIG. Surrounded by

The manufacture of the terminating spiral 10 in the winding device indicated by reference numeral 140 is shown approximately in FIG. 25. This winding device has two loop members 142 and 144, which are arranged at a constant distance from each other and have bearing surfaces 146 and 148 respectively circular in shape and are used as supports for the fiber strands 24. Where bearing surfaces 146 and 148 determine the next shape of loop 12.

Furthermore, the winding device has a central rod 150 extending between the loop members 142 and 144 to form a winding cord.

Furthermore, the two guide shoes 152,154 or 156,158 at the same radial distance from the center rod 150 and arranged in the longitudinal direction 160 of the center rod at the same distance from the corresponding loop members 142 and 144 are also loop members. It is associated with (142,144). In order to manufacture the two terminating spirals 10, a plurality of adjacent fiber strands 24 in the plane 164 containing flat cords or a plurality of adjacent fibers covered in a sheath in the plane 164 of flat cords Flat cords 162 consisting of strands 124, 224, 324 or synthetic fiber cords 432, 532 or 632 or a plurality thereof are placed around the loop members 142 and 144 as well as all guide shoes 152 to 158. In the case of synthetic fiber cords 432, 532 or 632, each fiber strand 24 is also located in the plane 164 of the flat cord.

The flat cord 162 is preferably hung around the loop members 142, 144 as well as the guide shoes 152-158 like endless belts with closed sides.

As shown in FIGS. 26 and 27, the configuration of the winding device 140 is characterized in that each of the loop members 142, 144 moves in the longitudinal direction 160 of the center rod 150, with the loop member carriers 170, 172 moving. And guided to slideways 174 and 176, respectively. Each slideway 174, 176 is mounted on a respective rotating support 178, 180 or 182, 184 which is arranged on each side of the loop member carrier 170, 172 respectively and it is about the longitudinal direction 160 of the central rod 150 acting as the axis of rotation. You can rotate the. Therein, the rotary support members 180 and 184 are rotatably mounted to the central rod 150. The rotary support members 178 and 182 are driven in the opposite directions of rotation, respectively. However, it is preferably driven at the same rotational speed by motor shafts 186, 188 of a motor (not shown).
