Description

Woven inhaul cable, reinforced inhaul 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 the excellent performances of light weight, high tensile strength, no metal fatigue, good weather resistance and the like, and has the trend of replacing the traditional steel cable in the engineering field. However, the carbon fiber is in a loose tow form of 12K/24K/48K, and can not form a guy cable without proper processing, and can not be used for engineering.

The current woven guy wires are made of a plurality of carbon fiber reinforced CFRP twisted strands, which are called CFCC in the industry. During the manufacture, the carbon fiber is firstly manufactured into single fiber ribs with the diameter of 5-11 mm through the pultrusion, the pultrusion process is actually the process of composite molding of the carbon fiber and the resin material, and then 7/19/37 single ribs are twisted to form the stranded wire CFCC. Chinese patent No. CN101525864B basalt fiber composite rib and basalt fiber composite inhaul cable, and the construction and manufacture of the inhaul cable are disclosed.

For the CFCC stranded wire, as the carbon fibers are only unidirectionally distributed, besides good longitudinal stretching property, the transverse property is poor, and the CFCC stranded wire is not resistant to compression and shearing, so that another difficulty is brought: and the anchoring problem of the end of the inhaul cable. All the anchoring clamps exert a lateral force on the CFRP, even if glue is filled and external pressure is applied, essentially a lateral force on the carbon fibers. The strength of the carbon fiber is tensile force, the axial force of the fiber tows, and the transverse force is the weak term of the carbon fiber, which is the problem: the lateral pressure of the anchor is small and not grasped, and the lateral pressure of the anchor is large and easily causes side damage of the carbon fiber, thereby destroying the overall strength of the CFRP. This approach also brings another engineering limitation in that the cross-sectional area of the CFCC cable cannot be made too large, and although the tensile strength of the CFCC is proportional to the cross-sectional area, the difficulty of anchoring the CFCC is also proportional to the cross-sectional area, ultimately limiting the engineering application of the cable.

When the CFCC is manufactured, the CFRP ribs are manufactured by mixing and pultrusion of resin materials and carbon fibers, and then the CFRP ribs are twisted and stranded into the inhaul cable with certain thickness. In the CFRP rib, the resin material is mainly used as a binder to combine loose carbon fiber tows into a whole through infiltration, cladding and solidification of the 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 CFCC cables by twisting. The combination of the fibers and the strings forms a thicker guy cable, and the guy cable is required to have force converging towards the central axis, so that the fibers and the strings are pulled more tightly when the two ends of the guy cable are stressed and stretched. Twisting has the effect of converging the strands of fiber/rope toward the central axis. The wire rope is also such that a plurality of thin wires are twisted to form a thick wire rope. However, the inability of carbon fibers to resist twisting makes this most commonly used method of making ropes unusable for carbon fiber ropes.

Disclosure of Invention

The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the invention provides a woven inhaul cable which can manufacture carbon fiber tows into inhaul cables meeting requirements without using high polymer resin materials.

When the two ends of the woven inhaul cable are stretched and stressed, the fiber tows forming the woven inhaul cable can be tightly held by the force converging in the middle, so that the effect of being pulled and tightened is achieved. At the same time, the woven pull cord can twist, and the pull cord can bear S or Z twist because the weft yarn rotates clockwise and counterclockwise. Because the woven inhaul cable has good twisting characteristics, a plurality of inhaul cable units can be used for twisting to form a thicker and stronger woven inhaul cable.

In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. 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, an embodiment of the present invention discloses a woven cable, as shown in fig. 1a and 1b, comprising a cable unit comprising a warp portion and a weft portion.

Specifically, the warp portion includes a first set of warp yarns 110 and a second set of warp yarns 120, each of the first set of warp yarns 110 and the second set of warp yarns 120 having a plurality of warp yarn bundles 111,121, the first set of warp yarns being annularly arranged, the second set of warp yarns also being annularly arranged, the two annularly arranged forming a figure 8; the trend of each warp yarn bundle 111,121 is consistent with the axial direction of the inhaul cable unit; the weft portion includes weft yarn bundles that are continuously 8-shaped coil-interwoven with warp yarn bundles 111 of the first group of warp yarns 110 and warp yarn bundles 121 of the second group of warp yarns 120, respectively, while spirally extending in an axial direction of the stay unit to form a tightly woven interwoven cord-like fabric. In the radial plane of the stay unit, the movement direction of the weft yarn tows in the annular interweaving shed of the first set of warp yarns 110 is a first direction, the movement direction of the weft yarn tows in the annular interweaving shed of the second set of warp yarns 120 is a second direction, the first direction is opposite to the second direction, and the projected contour of the first weft yarn tows 210 presents an 8-shape. The first direction is either clockwise or counter-clockwise. The first direction and the second direction are opposite to each other, and refer to: when the first direction is clockwise, the second direction is counterclockwise; when the first direction is counterclockwise, the second direction is clockwise. The motion track of the weft yarn tows is in a 8-shaped double-rotation mode, one 8-shaped part is in a circle, and multiple circles spirally extend along the axial direction of the inhaul cable unit to form a rope-shaped fabric with warp yarns and weft yarns tightly interwoven.

As one example, referring to fig. 1a, fig. 1a shows a schematic structural view of a single-shuttle woven cable. In the illustration, the first weft yarn bundle 210 makes a figure-8 revolution around the first set of warp yarns 110 and the second set of warp yarns 120, the first weft yarn bundle 210 moves clockwise around the first set of warp yarns 110 and counterclockwise around the second set of warp yarns 120, referred to as a double revolution, and the resulting warp and weft interweaving structure is referred to as a double revolution. Simultaneously with the rotation of the first weft yarn bundle 210, the first weft yarn bundle 210 synchronously axially displaces, the axial displacement is defined as the weft distance d after the first weft yarn bundle 210 completes 8-shaped rotations of one period, the intersection point of the first weft yarn bundle 210 and the central axis 130 is defined as a half-distance point when the first weft yarn bundle 210 performs double rotation, the half-distance point is a conversion point of clockwise motion and anticlockwise motion of weft yarn, and the axial displacement of the weft yarn between the two half-distance points is 0.5d. Wherein, the first weft yarn tow 210 is synchronously displaced along the axial direction by the way that the traction device 520 pulls the weaving inhaul cable to axially move. In fig. 1a, a first set of warp yarns 110 schematically depicts two warp yarn bundles 111, as can be seen from the illustration that the warp yarn bundles 111 are plain interwoven with a first weft yarn bundle 210; the second set of warp yarns 120 is also schematically depicted as two warp yarn bundles 121, and it can be seen from the illustration that the warp yarn bundles 121 are plain interwoven with the weft yarns. The projection of the first weft yarn bundle 210 in the axial direction of the stay unit presents an 8-shaped double turn trajectory, as shown in fig. 1 b.

It should be understood that the schematic view in fig. 1a is only for the sake of clarity of the motion trajectory of the first weft yarn bundle 210 and the interweaving of warp yarn bundles 111,121 with the first weft yarn bundle 210. In actual weaving, both warp yarn bundles 111,121 and first weft yarn bundle 210 are gathered by a relatively high tension, and warp yarn bundles 111 of the first group of warp yarns and warp yarn bundles 121 of the second group of warp yarns 120 are gathered together to form a woven stay with an oblate cross section (8-shaped profile).

In some embodiments, referring to fig. 2, fig. 2 shows a schematic structural view of a single-shuttle woven cable. In the figure, the first set of warp yarns 110 and the second set of warp yarns 120 each depict ten warp yarn bundles 111,121. It should be appreciated that, in actual manufacturing, the number of warp tows 111,121 is several times that of the illustration, and the monofilament cross sections of the warp tows 111,121 are not circular as illustrated, but the warp tows 111,121 are gathered together very tightly under the effect of the winding and binding tension of the first weft tow 210, especially the portion (the portion corresponding to the jacquard opening "up") surrounded by the first weft tow 210 is gathered completely into one bundle by the first weft tow 210, and the warp tows 111,121 are not separated; the portion of the first weft yarn bundle 210 that is looped around (the portion corresponding to the "down" pattern openings) in turn tightly wraps around and presses the first weft yarn bundle 210, and 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 greater. Since the tensile strength of the woven stay is mainly dependent on the total cross-sectional area of the warp tows 111,121, the total cross-sectional area of the corresponding warp tows 111,121 must be ensured when designing the woven stay, and carbon fiber tows having good tensile strength are used as the warp tows 111,121. The first weft yarn bundles 210 may be made of carbon fibers of a lower grade to reduce cost, or may be made of other types of fibers with better flexibility to obtain better small radius winding and anti-twist properties, such as chemical or textile fibers. Further, the first weft yarn filament bundle 210 is a filament bundle with a flat ribbon-shaped section, so that the winding and wrapping effects are better. It should be noted that the warp yarn bundles 111 of the first set of warp yarns 110 should be identical to the warp yarn bundles 121 of the second set of warp yarns 120.

The woven inhaul cable with the double-rotation structure has certain twisting resistance. Since there are both clockwise-rotated first weft yarn tows 210 and counterclockwise-rotated first weft yarn tows 210 in one cable unit, the woven cable can withstand both S-and Z-twist, which changes the characteristic of carbon fiber untwisting. 3 or 5 cables … … can be used, and a plurality of the cable units can form thicker and stronger cables in a twisting mode.

In some embodiments, as shown in fig. 3a and 3b, the weft yarn tows include a first weft yarn tow 210 and a second weft yarn tow 220, the second weft yarn tow 220 is warp and weft interwoven with warp yarn tows 111 of the first set of warp yarns 110 and warp yarn tows 121 of the second set of warp yarns 120, respectively, and the second weft yarn tow 220 is mirror symmetrical to the first weft yarn tow 210 with respect to the central axis 130 of the cable unit. It should be appreciated that the first weft yarn bundles 210 are continuously 8-shaped coil interwoven with the warp yarn bundles 111 of the first group of warp yarns 110 and the warp yarn bundles 121 of the second group of warp yarns 120, respectively, while spirally extending in the axial direction of the stay unit to form a tightly woven interwoven cord-like fabric; the second weft yarn bundles 220 are also continuously 8-shaped coil-interwoven with the warp yarn bundles 111 of the first group of warp yarns 110 and the warp yarn bundles 121 of the second group of warp yarns 120, respectively, while spirally extending in the axial direction of the stay unit to form a tightly woven interwoven cord-like fabric.

In fig. 3a, a first weft yarn bundle 210 is wound clockwise in a first set of warp yarns 110 and counterclockwise in a second set of warp yarns 120; the second weft yarn bundle 220 is wound clockwise at the second set of warp yarns 120, counterclockwise at the first set of warp yarns 110, and the first weft yarn bundle 210 is mirror-image with respect to the central axis 130 of the woven cable. Wherein the clockwise or counterclockwise direction refers to the direction when looking from the end to be woven of the woven inhaul cable to the end which is woven.

As one example, fig. 4 shows a schematic structural diagram of a double-shuttle double-swivel woven cable. In the illustration, the first set of warp yarns 110 and the second set of warp yarns 120 each depict ten warp yarn bundles 111,121. It should be appreciated that in actual manufacture, the number of warp tows 111,121 is several times that shown, and that the cross section of warp tows 111,121 is not circular as shown, but rather that warp tows 111,121 are gathered very tightly together under the wrapping tension of first weft yarn tow 210, without separating warp tows 111,121 one by one. The first weft yarn strands 210 are wrapped by warp yarn strands 111,121 and are not readily visible on the outer surface.

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

In some embodiments, warp tows 111,121 and/or 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, metal fibers.

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

In some embodiments, warp tows 111,121 and/or weft tows are carbon fiber factory precursors or process tows.

The processing tows can be weaving processing tows, braiding processing tows, spreading tows, doubling tows and the like.

In another aspect, the reinforcing cable of the embodiment of the invention comprises a plurality of woven cables as described above, and a plurality of the woven cables are processed by weaving, braiding or twisting to obtain thicker and stronger woven cables.

An embodiment of the invention further discloses a guy cable weaving method, which is applied to the guy cable weaving equipment, wherein the first shuttle car operates according to the following steps to keep the weft yarn smooth and untwisted during 8-shaped double-rotation movement:

s170, executing S110 in a circulating way.

In some embodiments, the shuttle comprises a first shuttle and a second shuttle, the first shuttle and the second shuttle operate according to the following steps to keep the weft yarn smooth and free of twisting when performing 8-shaped double-rotation movement:

s280, at the moment, the first shuttle car parks and waits in the 1 partition;

s290, the loop execution S200.

The dragline 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, the traction device and the yarn feeding device to complete the weaving of the 8-shaped double-rotary-structure inhaul cable. The system also comprises a human-computer interface for realizing human-computer interaction.

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

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

	Warp yarn
		Zone 1	18 roots
Zone 2	21 roots of
		Zone 3	21 roots of
Zone 4	18 roots
		Zone 5	18 roots
Zone 6	21 roots of
		Zone 7	21 roots of
Zone 8	18 roots
		Totalizing	156 root

The weave of the warp and weft yarns is twill, so that the ratio of the warp yarn surrounded by the weft yarn (shed opening is up) to the warp yarn peripherally pressed against the weft yarn (shed opening is down) is 2:1, the circumferential distribution density of warp yarn is comparable to the core distribution density surrounded by weft yarn, so the number of warp yarns per section is a multiple of 3. Zone 1, zone 4 of the upper set, and zone 5, zone 8 of the lower set, overlap with the weft yarn being tight, so that some warp yarns are seldom assigned. The breaking force of 156 warp yarns is 72T, thereby meeting the design requirement.

The weft yarn is also selected from the same carbon fiber tows, and the weft distance can be defined within the range of 10-20 mm. The contribution of the weft yarn to the tensile strength of the inhaul cable is small and negligible. The weft distance greatly affects the appearance of the inhaul cable, the weaving compactness is high when the weft distance is small, and the free length of warp yarn bundles is small; if the weft distance is large, the weaving compactness is low, the free length of the warp yarn bundles is large, the possibility that the appearance is locally and sporadically scattered yarn and bounced yarn is high, but the weaving efficiency is higher.

The cross section of the inhaul cable woven in the way is a ribbon inhaul 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 relatively brittle, not resistant to bending and twisting, and the parallel loose of the tows fibers can not be used in engineering. The 8-shaped double-rotation structure of the invention has the advantages of enhanced weaving, certain load capacity, compact appearance, bending and twisting of the inhaul cable, and can be applied to various projects. The plurality of the cables can further form a thicker reinforcing cable by twisting. If such a stay is used as warp, about 140 such warp yarns, a stay of ten thousand tons level can still be woven with the technical scheme of the present invention. This is not achieved by the prior art.

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