Description

Sight hose cover

Technical Field

Aspects of the present invention generally relate to hose covers, and more particularly, to hose covers designed for high pressure hoses.

Background

High pressure hoses present a danger to people located in the surrounding area. High pressure hoses, such as hydraulic hoses provided on machinery, present a risk to persons exposed around the machinery if the hose fails under high pressure.

Generally, high pressure hoses have two modes of failure: catastrophic burst/rupture or pinhole failure. Large areas of hose failure can occur when the hose experiences catastrophic burst failure. This type of failure is often explosive because the hose releases a large amount of fluid under high pressure. People in the area surrounding the hose may have fluid splashed onto them, and the fluid may be extremely hot or toxic. In some cases, the high pressure hose includes a metal housing or cover. During hose rupture, pieces of the hose may be ejected at high speed, becoming fragmented, and potentially injuring people in the area.

In a pinhole mode of failure, the hose may exhibit a small hole in the wall of the high pressure hose. The remainder of the hose remains intact and the fluid maintains a relatively high pressure within the hose. When fluid escapes from the hose through the pinhole at very high pressure, a high pressure fluid jet is formed. High pressure jets can seriously injure surrounding people. For example, fluid escaping from a needle hole may cause amputation of a body part and/or may puncture the skin and eject fluid beneath the skin. The fluid sprayed beneath the skin may be oil, which can cause serious injury, blood poisoning, and/or amputation of body parts requiring damage. Also, the fluid jet can pierce a protective garment, such as a glove.

Thus, there is a need to protect people in the area of high pressure hoses from catastrophic rupture, pin hole failure, and other failures of the high pressure hose.

Detailed Description

Fig. 1-13 show a hose cover 10 according to a form of the present invention. As shown in fig. 1, the hose cover 10 includes an inner sheath 14, a middle sheath 16, and an outer sheath 18. The hose cover 10 can be considered to have a first layer 20, a second layer 22, a third layer 24, a fourth layer 26, a fifth layer 28, and a sixth layer 30. The first layer 20 and the sixth layer 30 together form the outer jacket 18. Alternatively, the outer jacket 18 may be considered to have a top layer 20 and a bottom layer 30. The second layer 22 and the fifth layer 28 together form the middle jacket 16. Alternatively, the middle jacket 16 can be considered to have a top layer 22 and a bottom layer 28. The third layer 24 and the fourth layer 26 together form the inner sheath 14. Alternatively, inner sheath 14 may be considered to have a top layer 24 and a bottom layer 26.

In use, a hose 12, such as a high pressure hose, is disposed between the openings formed between the third layer 24 and the fourth layer 26 of the inner sheath 14. As shown in FIG. 1, the inner 14, middle 16 and outer 18 sheaths all surround the hose 12.

The inner sheath 14, the middle sheath 16, and the outer sheath 18 each have a braided structure formed by braiding yarns. The yarns may comprise a variety of different materials including, for example, nylon, polyester, and Kevlar^TMThe composite material of (1). OthersThe material may be selected based on the type of fluid circulating in the hose 12 or the operating environment in which the hose cover 10 will be used. For example, the material may be selected to help prevent degradation of the material of the hose cover 10 due to the fluid or environment in which the hose cover 10 will be used.

As shown in fig. 3, each of the first, second, third, fourth, fifth and sixth layers 20, 22, 24, 26, 28, 30 includes a plurality of warp yarns 32 extending in a generally longitudinal direction. As described further below, the hose cover 10 is formed by weaving six layers of yarn 32 simultaneously. Weft yarns 34 (also referred to as "weft" yarns or "lateral" yarns) that extend in a generally latitudinal direction in the hose cover 10 are woven between the warp yarns 32 in a pattern that interweaves all six layers together, with the weft yarns being common between all six layers. In some forms, the weft yarns may be polyester yarns of about 840 denier. In other forms, the weft yarns may be industrial filament polyester yarns, nylon, Nomex^TM、Kevlar^TMOr any other suitable yarn.

Fig. 2 and 3 show a six-layer weave pattern. As shown in fig. 3, each layer includes a plurality of warp yarns 32. As shown in fig. 2-3, the weft yarns 34 weave with the warp yarns 32 in the weft direction so that six layers are interwoven.

Fig. 4 is a picking diagram (also referred to as a chain diagram or cam diagram) of the hose structure 10. The horizontal rows of the squares represent the weaving path/course of the weft yarns and the vertical columns corresponding to the heddles of the weaving machine represent the warp yarn groups. The picking diagram of fig. 4 shows a weaving machine with thirteen heddles. When a square is shaded it means that the heddle corresponding to the square is lifted when a weft yarn is twisted through the weaving machine.

The threading diagrams of fig. 5A-5B show the placement of warp yarn 32 in a heddle to produce the hose cover 10 of fig. 1-3, while the picking diagram of fig. 4 shows the action of the heddle with respect to weft yarn 34 to produce a woven structure. The vertical axis of the threading diagrams of fig. 5A-5B represents the number of heddles of a weaving machine used to manufacture the hose cover 10. In some examples thirteen heddles are used in the manufacture of the hose cover 10. The bottom four heddles (heddles 1-4) comprise warp yarns forming an outer sheath 18, the middle four heddles (heddles 5-8) comprise warp yarns forming an inner sheath 16, and the next four heddles (heddles 9-12) comprise warp yarns forming an inner sheath 14. The top heddle (heddle 13) comprises warp yarns that reinforce the structural edges and seal the edges against leakage. The horizontal axis of fig. 5A-5B represents the yarn used to create the hose cover 10, with row 36 representing the number of repetitions of each segment of the drawing. For example, the first column of figure 5A shows a first yarn in a first heddle frame and a second yarn in a second heddle frame. The numbers shown in rows 44, 46, 48, 50 and 52 represent the filament count of each material used and are used during the loom configuration. For example, row 44 specifies using a yarn having a monofilament count of 230. In the first segment where the pattern repeats 24 times, the number 96 indicates the number of yarns used in that segment for that particular yarn type, while the number 4 indicates the number of yarns used in the second segment for that particular yarn type. Alternatively, if only a single color is used in the woven tape, the entire tape may be manufactured using only one segment. The structure shown in fig. 5A-5B includes several colors of yarns. The number of repetitions of each pattern may increase or decrease as the width of the woven structure increases or decreases. The hatching shown by reference numerals 40 and 42 indicates the use of colored yarns as the marker yarns in the desired segment. The hose cover may be formed on a Muller NF loom, but other suitable looms may be used.

With respect to some forms, the phrase "weft insertion pass" includes two picks, where one pick is produced in the top layer of one of the jackets and one pick is produced in the bottom layer of the other jacket. Thus, during the weaving pass (i.e. during the two weft insertion processes), the weft yarn 34 traverses from one layer to the next at each edge of the structure.

Fig. 6-13 are cross-sectional views of the hose cover 10 showing the pattern of weft yarns 34 interweaving the layers together. As shown in fig. 6 and 13, during the first weaving pass 54, the weft yarn 34 weaves the first layer 20 with the fourth layer 26 to connect a portion of the outer sheath 18 with a portion of the inner sheath 14. As shown in fig. 7 and 13, during the second weaving pass 56, the weft yarn 34 weaves the second layer 20 with the sixth layer 30 to connect a portion of the middle sheath 16 with a portion of the outer sheath 18. As shown in fig. 8 and 13, during the third weaving pass 58, the weft yarn 34 weaves the third layer 24 with the fifth layer 28 to connect a portion of the inner sheath 14 with a portion of the middle sheath 16. As shown in fig. 9 and 13, during the fourth weaving pass 54, the weft yarn 34 weaves the first layer 20 with the fourth layer 26 to connect a portion of the outer sheath 18 with the inner sheath 14. As shown in fig. 10 and 13, during a fifth weaving pass 56, the weft yarn 34 weaves the second layer 20 with the sixth layer 30 to connect a portion of the middle sheath 16 with the outer sheath 30. As shown in fig. 11 and 13, during the sixth weaving pass 58, the weft yarn 34 weaves the third layer 24 with the fifth layer 28 to connect a portion of the inner sheath 14 with the middle sheath 16. Fig. 12 and 13 show the weaving pattern of all six layers of weft yarns 34.

During each pick pass shown in fig. 6-13, the weft yarn 34 crosses at the outer edge an intersection 38 located substantially in the centre of the structure. Thus, the weft yarn 34 intersects the center of the structure at each pick pass. This helps maximize the strength of the structure at its edges by placing a greater number of weft yarns at the intersections 38. In some forms, as shown in fig. 12-13, the structure may include a second crossing point on the opposite side of the structure with which the weft yarn 34 crosses each pick pass.

Fig. 13 shows two intersections resulting from the weft insertion rows of fig. 6-11. Reference numeral 54 denotes a first and fourth weft insertion rows (also shown in fig. 6 and 9), reference numeral 56 denotes a second and fifth weft insertion rows (also shown in fig. 7 and 10), and reference numeral 58 denotes a third and sixth weft insertion row (also shown in fig. 8 and 11). Reference numeral 60 denotes the transition from one pick pass to another. The structure shown in fig. 13 also includes a knitted edge 62.

As shown in fig. 4 and 6-11, all layers of hose cover 10 are formed with an 1/1 weave (i.e., warp yarn 32 passes over weft yarn 34 and adjacent warp yarn 32 passes under weft yarn 34). Also, in some forms, a first weave pattern may be used when weaving one of the layers of one of the sheaths to one of the layers of the other sheath during a first pass. When the same two layers are woven together during the second pass, the weave pattern may be reversed. As shown when comparing fig. 6 and 9, for example, when the weft yarn 34 is twisted on the second pass to interweave these same two layers, the pattern of the lifting warp yarns of the first and fourth layers is reversed relative to the weft yarn. In other words, the warp yarns lifted during the weft insertion pass shown in fig. 6 are lowered during the weft insertion pass shown in fig. 9. In other forms, however, other weave patterns may be used.

Although the hose cover described above is a six-layer structure having an outer sheath, a middle sheath, and an inner sheath, the hose cover may include any number of layers and any number of sheaths interwoven together. In some examples, the hose cover has more than six layers, and in other examples has less than six layers. Any multi-layer hose cover having layers interwoven according to the principles described above is included within the scope of the present invention.

The multilayer hose cover 10 having warp yarns 32 and the weave pattern described above is subjected to testing to determine its effectiveness in accommodating high pressure hoses. According to one form of the invention, the warp yarn used for the outer jacket 18 is an air-jet bulked 2900 denier nylon yarn, which provides enhanced wear protection to the inner layer. The warp yarns for middle and inner sheaths 16 and 14 are flat 1680 denier nylon yarns having 2.5z twists per inch. In one example, the weft yarns 34 for all layers are flat 840 denier nylon yarns. In some examples, the third layer 24 and the fourth layer 26 of the inner sheath 14 include marker yarns to guide the positioning of the hose 12 between the two layers.

In some forms all six layers have a weft yarn density of 22 picks per inch. In this particular example, the outer sheath 18 has a warp density of 36.7 ends per inch. The fabric weight of outer jacket 18 is approximately 0.01377 ounces per square inch and has a thickness of 0.945 inches. In some forms, the inner sheath 14 and the middle sheath 16 have a warp density of 36.70 ends per inch. The fabric weighed approximately 0.00986 ounces per square inch and had a thickness of 0.034 inches. In other forms, the weight and thickness of the jacket varies depending on the fabric used, the denier, and the weave-in variations.

Different materials can be incorporated into the hose cover in different situations. For example, conductive and/or super-strong materials, such as Kevlar, may be used as desired^TMOr Spectra^TMA yarn.

The combination of yarns described above provides a tighter and thinner weave for the inner and middle sheaths than for the outer sheath, thereby providing lower penetration of the fabric of the inner and middle sheaths. A particular form of hose cover 10 is placed around the hydraulic hose and subjected to a burst test. The fluid pressure in the hose consistently increases until the hose breaks within the hose cover 10. The hose cover 10 remains intact and the energy of the escaping fluid is dissipated and the fluid seeps out of the hose cover 10 as desired without harm. Thus, the hose cover 10 described above accommodates hoses that burst until at least 13500 psi. Conventional hose covers are subjected to similar testing and are torn by escaping fluid at the location of the hose failure. Other forms with other weave patterns and/or different numbers of layers can accommodate higher psi burst hoses.

The particular form of hose cover 10 according to the present invention described above was subjected to an impact test to test the resistance of the hose cover to pinhole type failure. A small hole having a diameter of about 0.049 inches was drilled in the wall of the hydraulic hose and then a hose cover was placed around the hydraulic hose. The fluid pressure inside the hose was cycled at a rate of 60 cycles per minute to a test pressure of 4000 psi at a fluid temperature of 250 ° f. The hose cover remains intact, with the fluid seeping through the outer sheath of the hose cover at a lower energy. Thus, the hose cover 10 described above can be used with equipment that operates at least 4000 psi. A conventional hose cover is subjected to similar tests, the cover being fully penetrated by the fluid jet discharged from the bore in the hydraulic hose and the jet being discharged at high pressure. Other forms having other weave patterns and/or different numbers of layers may be used with devices operating at over 4000 psi.

Thus, the hose cover 10 provides protection against high energy bursts at high pressure and small holes in the hose that allow high velocity streams to escape. The energy of these types of failures is absorbed by the weave and interweaving of the hose cover. Specifically, the layers reinforce each other and spread the burst energy over a larger area of the hose cover 10, which allows the hose cover 10 to contain the burst-related energy while allowing fluid released due to hose failure to seep through the body of the cover around the failure zone. Outer sheath 18 serves as a wear layer, while middle sheath 16 and inner sheath 14 are tightly woven to dissipate energy associated with the burst. The concentration of fluid alerts personnel of a hose failure without causing injury to the personnel from the high energy release of the fluid.

As various changes could be made in the above exemplary forms described with reference to the corresponding illustrations without departing from the scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Thus, the breadth and scope of the present invention should not be limited by any of the above-described exemplary forms, but should instead be defined only in accordance with any of the claims appended hereto and their equivalents. Moreover, it is contemplated that one skilled in the art can use any or all of the features disclosed in the above-described forms in any compatible combination or arrangement.
