Description

Woven guy cable, reinforced guy cable, equipment and manufacturing method

Technical Field

The invention relates to the technical field of engineering inhaul cables, in particular to a woven inhaul cable, a reinforced inhaul cable, equipment and a manufacturing method.

Background

Currently, various high performance reinforcing fibers are increasingly being used in various fields. The carbon fiber has excellent performances of light weight, high tensile strength, no metal fatigue, good weather resistance and the like, and has a tendency of replacing the traditional steel cable in the engineering field. However, the outgoing precursor of the carbon fiber is in a loose tow form of 12K/24K/48K, and the carbon fiber cannot be formed into a guy cable without proper processing, and further cannot be used for engineering.

The existing woven inhaul cable is made of a plurality of Carbon Fiber Reinforced Plastic (CFRP) stranded wires, and the existing woven inhaul cable is called as a carbon fiber stranded wire (CFCC) in the industry. During manufacturing, carbon fibers are manufactured into single fiber ribs with the diameter of 5-11 mm through pultrusion, the pultrusion process is actually a process of composite molding of the carbon fibers and a resin material, and then 7/19/37 single ribs are twisted to form the stranded wire CFCC. The invention discloses a basalt fiber composite rib and a basalt fiber composite inhaul cable with Chinese patent No. CN101525864B, and discloses a composition and a manufacturing method of the inhaul cable.

Aiming at the CFCC stranded wire, because the carbon fibers are only unidirectionally distributed, the CFCC stranded wire has poor transverse property and is not resistant to compression and shearing except good longitudinal tensile property, and another problem is brought: the problem of anchoring the end of the inhaul cable. All the anchoring clamps exert a transverse force on the CFRP, which is essentially a lateral force on the carbon fibers, even if filled with glue and subjected to external pressure. The strength of the carbon fiber is tensile force, which is the axial force of the fiber tows, and the transverse force is the weak item of the carbon fiber, which is the problem: the lateral pressure of the anchor is small, the anchor cannot be caught, and the lateral pressure of the anchor is large, so that the lateral damage of the carbon fiber is easily caused, and the integral strength of the CFRP is damaged. The method also brings another engineering limitation, the sectional area of the CFCC inhaul cable cannot be too large, although the tensile strength of the CFCC inhaul cable is in direct proportion to the sectional area, the anchoring difficulty of the CFCC inhaul cable is also in direct proportion to the sectional area, and the engineering application of the inhaul cable is limited finally.

When the CFCC is manufactured, a resin material and carbon fibers are mixed and pultruded to manufacture CFRP ribs, and then a plurality of CFRP ribs are twisted and twisted to form the inhaul cable with certain thickness. The mechanical property of the resin material is poor, and the resin material is mainly used as a binder in the CFRP rib so as to combine loose carbon fiber tows into a whole through infiltration, coating and curing of a high polymer resin material. The carbon fiber is not twist-resistant, and can resist certain twisting after being made into CFRP ribs, so that a plurality of CFRP ribs can be processed into the CFCC inhaul cable in a twisting mode. The combination of the fiber/thin rope is thicker, and the force must be converged towards the central axis, so that when the two ends of the stay are stressed and stretched, the fiber/thin rope is more and more tensioned. The twisting has the effect of converging the strands of fibre/string towards the central axis. The steel cord is also a thick steel cord formed by twisting a plurality of thin steel wires. However, the non-twist resistance of carbon fibers makes this most commonly used method of making ropes impractical for carbon fiber ropes.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art. Therefore, the invention provides a woven cable, which can be used for manufacturing carbon fiber tows into cables meeting requirements without using a high polymer resin material.

The invention also provides inhaul cable weaving equipment for weaving the woven inhaul cable.

The invention also provides a guy cable weaving method for weaving the woven guy cable.

A woven wire according to an embodiment of the first aspect of the invention includes a wire unit including: a warp yarn section comprising a first set of warp yarns and a second set of warp yarns, each having a plurality of warp yarn tows, each warp yarn tow running in line with an axial direction of the cable unit; the first group of warp yarns are annularly arranged, the second group of warp yarns are also annularly arranged, and the two annuli form a figure 8; a weft yarn part which comprises weft yarn tows, wherein the weft yarn tows are respectively and spirally interwoven with the warp yarn tows of the first group of warp yarns and the warp yarn tows of the second group of warp yarns in a continuous 8-shaped manner and simultaneously extend along the axial direction of the inhaul cable unit to form a cord-shaped fabric with a tight weaving and interweaving structure; in a radial plane of the guy cable unit, the movement direction of the weft yarn tows in the annular interweaving shed of the first group of warp yarns is a first direction, the movement direction of the weft yarn tows in the annular interweaving shed of the second group of warp yarns is a second direction, the first direction is opposite to the second direction, and the projection outline of the first weft yarn tows is in a shape of a letter 8, wherein the first direction is a clockwise direction or a counterclockwise direction; the movement track of the weft yarn tows is 8-shaped double rotation, one 8 shape is a circle, and a plurality of circles spirally extend along the axial direction of the inhaul cable unit to form the cord-shaped fabric with the warp yarns and the weft yarns tightly interwoven.

When the two ends of the woven inhaul cable are stretched and stressed, the fiber tows forming the woven inhaul cable can be held tightly by the force gathered inwards, and therefore the effect that the inhaul cable is pulled more and more tightly is achieved. At the same time, the woven cable can twist, and the weft yarn rotates clockwise and anticlockwise, so that the cable can bear S twist or Z twist.

In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

In one aspect, the embodiment of the invention discloses a woven cable, as shown in fig. 1a and 1b, the woven cable comprises a cable unit, and the cable unit comprises a warp yarn part and a weft yarn part.

Specifically, the warp yarn part comprises a first group of warp yarns 110 and a second group of warp yarns 120, the first group of warp yarns 110 and the second group of warp yarns 120 are both provided with a plurality of warp yarn tows 111,121, the first group of warp yarns are annularly arranged, the second group of warp yarns are also annularly arranged, and the two annuluses form an 8 shape; the direction of each warp yarn bundle 111,121 is consistent with the axial direction of the inhaul cable unit; the weft yarn part comprises weft yarn tows which are respectively interwoven with the warp yarn tows 111 of the first group of warp yarns 110 and the warp yarn tows 121 of the second group of warp yarns 120 in a continuous 8-shaped winding manner and simultaneously extend spirally along the axial direction of the stay cable unit so as to form a cord-like fabric with a tight woven interweaving structure. In a radial plane of the dragline unit, the moving direction of the weft yarn bundle in the annular interweaving shed of the first group of warp yarns 110 is a first direction, the moving direction of the weft yarn bundle in the annular interweaving shed of the second group of warp yarns 120 is a second direction, the first direction is opposite to the second direction, and the projected outline of the first weft yarn bundle 210 is in a shape of a letter 8. The first direction is either clockwise or counterclockwise. The aforementioned first direction is opposite to the second direction: when the first direction is clockwise, the second direction is anticlockwise; when the first direction is counterclockwise, the second direction is clockwise. The motion track of the weft yarn tows is 8-shaped double rotation, one 8 shape is a circle, and a plurality of circles spirally extend along the axial direction of the inhaul cable unit to form the cord-shaped fabric with tightly interwoven warp yarns and weft yarns.

Referring to fig. 1a, fig. 1a shows a schematic structural view of a single-shuttle woven traction cable as an example. In the illustration, the first weft yarn bundle 210 makes 8-shaped turns around the first set of warp yarns 110 and the second set of warp yarns 120, the first weft yarn bundle 210 makes clockwise motion around the first set of warp yarns 110 and counterclockwise motion around the second set of warp yarns 120, which is called double-turn motion, and the resulting warp and weft interweaving structure is called double-turn structure. When the first weft yarn bundle 210 rotates, the first weft yarn bundle 210 synchronously and axially displaces, when the first weft yarn bundle 210 completes 8-shaped rotation of one period, the axial displacement is defined as a weft distance d, the intersection point of the first weft yarn bundle 210 and the central axis 130 during double rotation is defined as a half-distance point, the half-distance point is a switching point of clockwise motion and anticlockwise motion of weft yarns, and the axial displacement of the weft yarns between the two half-distance points is 0.5d. Wherein, the synchronous displacement of the first weft yarn bundle 210 along the axial direction is realized by pulling the woven inhaul cable to axially move through the traction device 520. In FIG. 1a, the first set of warp yarns 110 schematically depicts two warp tows 111, which show that the warp tows 111 are plain interwoven with the first weft tows 210; the second set of warp yarns 120 is also schematically illustrated with two warp tows 121, and it can be seen that the warp tows 121 are woven in a plain weave with the weft yarns. The projection of the first weft yarn bundle 210 in the axial direction of the guy cable unit appears as an 8-shaped double-turn track, as shown in fig. 1 b.

It should be understood that the schematic illustration in fig. 1a is only for the sake of clarity of the movement path of the first weft yarn bundle 210 and the interweaving of the warp yarn bundles 111,121 with the first weft yarn bundle 210. In the actual weaving process, the warp yarn bundles 111,121 and the first weft yarn bundle 210 are tightened with a large tension, and the warp yarn bundle 111 of the first group of warp yarns and the warp yarn bundle 121 of the second group of warp yarns 120 are folded into one, so that the woven cable with an oblate cross section (8-shaped contour) is formed.

In some embodiments, referring to fig. 2, fig. 2 shows a schematic structural view of a single-shuttle woven traction cable. In the figure, the first set of warp yarns 110 and the second set of warp yarns 120 depict ten warp yarn tows 111,121, respectively. It should be understood that, in actual manufacturing, the number of the warp yarn bundles 111,121 is several times that of the illustrated warp yarn bundles, and the monofilament cross sections of the warp yarn bundles 111,121 are not circular as illustrated, but under the action of the wrapping and binding tension of the first weft yarn bundle 210, the warp yarn bundles 111,121 are gathered together very tightly, especially the portion (corresponding to the portion where the jacquard openings are "on") surrounded by the first weft yarn bundle 210 is looped and gathered into one bundle by the first weft yarn bundle 210, and one warp yarn bundle 111,121 cannot be separated; while the portion of the first weft yarn bundle 210 that is wrapped in a circular shape (corresponding to the portion with the jacquard openings "under") in turn wraps tightly around the first weft yarn bundle 210, the first weft yarn bundle 210 is not easily visible on the outer surface when the density of the wrapped warp yarn bundles 111,121 is high. Since the tensile strength of the woven cable is mainly determined by the total cross-sectional area of the warp tows 111,121, when designing the woven cable, it is necessary to secure the total cross-sectional area of the corresponding warp tows 111,121, and to use carbon fiber tows having good tensile strength as the warp tows 111,121. The first weft yarn bundle 210 may be made of a lower grade carbon fiber to reduce cost, or other types of fibers with better flexibility to achieve better small radius winding characteristics and twist resistance, such as chemical or textile fibers. Further, the first weft yarn tows 210 are flat ribbon-shaped in cross section, and the winding and wrapping effects are better. It should be noted that the warp tows 111 of the first set of warp yarns 110 should be the same as the warp tows 121 of the second set of warp yarns 120.

The woven inhaul cable with the double-rotation structure has certain twisting resistance. Because the clockwise-rotated first weft yarn bundle 210 and the anticlockwise-rotated first weft yarn bundle 210 exist in one cable unit at the same time, the woven cable can bear S twist and Z twist, and the characteristic that carbon fibers are not twist-resistant is changed. 3, 5 pieces of the guy cable units can be used for the guy cable unit, 8230, and a plurality of the guy cable units form a thicker and stronger guy cable in a twisting mode.

In some embodiments, as shown in fig. 3a and 3b, the weft yarn bundles include a first weft yarn bundle 210 and a second weft yarn bundle 220, the second weft yarn bundle 220 is interwoven with the

warp yarn bundles

111 and 121 of the first and second sets of

warp yarns

110 and 120, respectively, and the second weft yarn bundle 220 is mirror symmetric to the first weft yarn bundle 210 with respect to the central axis 130 of the cable unit. It will be appreciated that the first weft yarn bundles 210 are respectively intertwined with the warp yarn bundles 111 of the first set of warp yarns 110 and the warp yarn bundles 121 of the second set of warp yarns 120 in a continuous 8-shaped winding and simultaneously extend helically in the axial direction of the guy cable unit to form a cord-like fabric of a tightly woven interweaving structure; the second weft yarn bundle 220 is also spirally interlaced with the warp yarn bundle 111 of the first group of warp yarns 110 and the warp yarn bundle 121 of the second group of warp yarns 120 in a continuous 8-shaped winding manner and at the same time extends in the axial direction of the stay cable unit to form a cord-like fabric of a tightly woven weave.

In FIG. 3a, the first weft yarn bundle 210 is wound clockwise at the first set of warp yarns 110 and counterclockwise at the second set of warp yarns 120; the second weft yarn bundle 220 is wound clockwise at the second set of warp yarns 120 and counterclockwise at the first set of warp yarns 110, and the first weft yarn bundle 210 is mirror-symmetrical with respect to the central axis 130 of the woven cable. The clockwise or counterclockwise direction is a direction when viewed from the end to be woven of the woven cord to the woven end.

As an example thereof, as shown in fig. 4, fig. 4 is a schematic view showing a structure of a double-shuttle double-rotary woven traction cable. In the illustration, the first set of warp yarns 110 and the second set of warp yarns 120 depict ten warp yarn tows 111,121, respectively. It is understood that, in actual manufacturing, the number of the warp yarn bundles 111,121 is several times that shown, and the cross section of the warp yarn bundles 111,121 is not circular as shown, but under the effect of the winding and binding tension of the first weft yarn bundle 210, the warp yarn bundles 111,121 are gathered together very tightly, and no one warp yarn bundle 111,121 is separated. The first weft yarn bundle 210 is wrapped by the warp yarn bundles 111,121 and is also not readily visible on the outer surface.

It should be noted that for the convenience of distinguishing the first weft yarn bundles 210 from the second weft yarn bundles 220, in fig. 3a, 3b and 4, the second weft yarn bundles 220 are represented by slightly thinner lines than the first weft yarn bundles 210, and in practical applications, the first weft yarn bundles 210 and the second weft yarn bundles 220 may be the same in thickness.

In some embodiments, the warp tows 111,121 and/or the weft tows are one or more of carbon fibers, basalt fibers, aramid fibers, ultra-high molecular weight polyethylene fibers, glass fibers, quartz fibers, ceramic fibers, and metal fibers.

In some embodiments, the warp tows 111,121 and the weft tows may be a combination of the same type of fiber or a combination of different types of fiber tows, such as: the warp yarn tows 111 and 121 are carbon fiber tows, and the weft yarn tows are chemical fiber tows or textile fibers.

In some embodiments, the warp tows 111,121 and/or the weft tows are carbon fiber factory precursor or processed tows.

Wherein the processed tows can be woven processed tows, braided processed tows, spread tows, doubled tows and the like.

The reinforced inhaul cable of another aspect embodiment of the invention comprises a plurality of woven inhaul cables as described above, and the plurality of woven inhaul cables are processed in a weaving, braiding or twisting mode to obtain thicker and stronger woven inhaul cables.

In another aspect, the present invention discloses a guy weaving apparatus, as shown in fig. 5 to 10, which includes an

The inhaul cable weaving equipment comprises 8 independent electrically-driven electronic jacquard shedding devices, a digitally-controlled traction device, a creel yarn supply device with tension control and a shuttle car capable of moving back and forth; a loom control system is required to control the shedding device, the shuttle car, the traction device and the yarn supply device to complete inhaul cable weaving of the 8-shaped double-rotation structure. The system also comprises a human-computer interface to realize human-computer interaction.

A carbon fiber double-rotation inhaul cable is designed, and the breaking tension is about 70T.

Selecting T700 carbon fiber and 24K tows, and according to the requirement of 70T breaking force, the number of warp yarns is not less than 152, considering the symmetry of upper and lower groups, each group has 4 opening subareas, and the distribution of the warp yarns in each area and the total number of the warp yarns are as follows:

	warp yarn
		Region 1	18 root of Chinese angelica
Zone
	2	21 root of Chinese goldthread
Zone
	3	21 root of Chinese goldthread
Zone 4			18 root of Chinese angelica
	Zone
5		18 root of Chinese angelica
	Zone
6		21 root of Chinese angelica
	Zone
7		21 root of Chinese goldthread
	Zone
8		18 root of Chinese angelica
	Total up to		156 root of

The woven weave of the warp and weft yarns is twill, so that the ratio of the warp yarns surrounded by the weft yarns (the shed opening is upper) to the warp yarns peripherally pressing the weft yarns (the shed opening is lower) is 2: the distribution density of the circumference of the warp yarn is equivalent to that of the core part surrounded by the weft yarn, so that the number of the warp yarns in each subarea is a multiple of 3. Zone 1 and zone 4 of the upper set will be joined to zone 5 and zone 8 of the lower set and will overlap in the event of a take-up of weft yarns, so that less warp yarns are distributed. The breaking tension of 156 warps is 72T, and the design requirements are met.

The weft yarns are made of the same carbon fiber tows, and the weft pitch can be determined within the range of 10-20 mm. The weft yarns contribute little to the tensile strength of the tensile cord and are negligible. The weft distance has great influence on the appearance of the inhaul cable, the weaving tightness is high when the weft distance is small, and the free length of warp yarn tows is small; the weaving compactness is low when the weft distance is large, the free length of warp yarn bundles is large, the possibility of yarn flying and yarn jumping of partial accidental hairs on the appearance is high, and the weaving efficiency is high.

The cross section of the cable woven in the way is a band-shaped cable with an oblate shape (8-shaped outline), the outline width is about 18-20mm, and the outline thickness is about 9-10mm. The carbon fiber tows are brittle, cannot resist bending and twisting, are parallel and loose among tow fibers and cannot be applied in engineering. The 8-shaped double-rotation structure of the invention has the advantages of enhanced machine weaving, certain loading capacity, compact appearance, bending and twisting inhaul cable, and can be applied to various projects. A plurality of the cables can be further formed into a thicker reinforced cable in a twisting mode. If the guy cable is used as a warp yarn, about 140 warps can weave a guy cable with ten thousand tons grade by using the technical scheme of the invention. This is not achievable by the prior art.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
