Abstract
The utility model belongs to the exhaust ventilation device technique field of the underground construction such as mine, tunnel, be particularly related to a kind of high strength two-way seamless air duct in length and breadth, comprise casing play, inside and outside coat, anti-limit, end circle and buttonhole selvage, end circle is fixedly arranged on the two ends of air duct, and end circle is outer to be encased by anti-limit; Casing play is between inside and outside coat, and intermedium rack-layer, inside and outside coat and buttonhole selvage are one-body molded, and buttonhole selvage is provided with fixing suspension ring.Each layer of the utility model air duct by plasticizing one-shot forming, do not have seam, air duct intensity is high, air leak rate of air curtain is low, has saved the long steel wire that penetrates buttonhole selvage simultaneously, buttonhole selvage is thickeied and is worked out flexible high-intensity stranded rope, has improved the safety of the engineer operations such as mine, down-hole, tunnel.
Description
Technical field
The utility model belongs to the exhaust ventilation device technique field of the underground construction such as mine, tunnel, particularly a kind of high strength two-way seamless air duct in length and breadth.
Background technology
The ventilation air duct of underground construction is mostly removed from office by rubber or plastics are made, blank is plain cloth shape, while making air duct, must longitudinally sew up or bonding, an outer affixed buttonhole selvage for hanging, there is seam in the air duct which is made, intensity effect to air duct is larger, makes the operation of the underground constructions such as mine, down-hole and tunnel have potential safety hazard.
Patent No. ZL200720109796.X discloses a kind of high power seamless plastic air duct, comprise outer coat, seamless pipe inner surface sealant, steel ring, anti-limit, seamless intermedium rack-layer, special buttonhole selvage, steel wire and hang by aluminium circle, seamless intermedium rack-layer between outer coat and seamless inner surface sealant, special buttonhole selvage and seamless intermedium rack-layer are made one, steel wire is positioned at Special-purpose hanger limit, and arrange along Special-purpose hanger edge lengths direction, hang and distribute along Special-purpose hanger edge lengths direction with aluminium circle, and be positioned at steel wire below.Above-mentioned patented product is with there not being seam, but its steel wire penetrates special buttonhole selvage along its length, and special buttonhole selvage is thin, intensity is low, is easily torn and is air leakage phenomena, causes underground construction operation to have potential safety hazard.
Utility model content
The utility model discloses a kind of flexible high-intensity two-way seamless air duct in length and breadth, it is low, easy to crack that it has solved current seamless air duct buttonhole selvage place intensity, causes underground construction operation to have the technical problem of potential safety hazard.
The technical solution of the utility model is as follows: a kind of high strength is two-way seamless air duct in length and breadth, comprises casing play, inside and outside coat, anti-limit, end circle and buttonhole selvage, and end circle is fixedly arranged on the both sides of air duct, and end circle is outer to be encased by anti-limit; Casing play, between inside and outside coat, is installed with buttonhole selvage on casing play, it is characterized in that, is provided with coat and buttonhole selvage is one-body molded inside and outside intermedium rack-layer, and buttonhole selvage is provided with fixing suspension ring, and described suspension ring are high duty metal circle.
Described inside and outside coat is seamless coat, and intermedium rack-layer adopts h braiding to form.
Each layer of the utility model air duct by plasticizing one-shot forming, and product main body is the two-way seam that all do not exist in length and breadth, and the intensity of air duct is high, air leak rate of air curtain is low; Meanwhile, saved the long steel wire that penetrates buttonhole selvage, buttonhole selvage is thickeied and is woven flexible high-intensity stranded rope, has greatly strengthened the intensity of buttonhole selvage, has improved the safety of the engineer operations such as mine, down-hole, tunnel.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Wherein: 1, outer coat; 2, interior coat; 3, anti-limit; 4, intermedium rack-layer; 5, hang
Limit; 6, suspension ring; 7, end circle; 8, Neto; 9, flexible high-intensity stranded rope.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1, 2, be fixedly installed end circle 7 outside the two ends of air duct, end circle 7 is encased by anti-limit 3.Intermedium rack-layer 4 is between interior coat 2 and outer coat 1, interior coat 2, outer coat 1 are seamless coat, intermedium rack-layer 4 adopts h to be woven into, interior coat 2, intermedium rack-layer 4, outer coat 1 and buttonhole selvage 5 are one-body molded by plasticizing, buttonhole selvage 5 weaves flexible high-intensity stranded rope, thickening buttonhole selvage 5, reinforcement Neto 8 increase the intensity at buttonhole selvage 5 places, are connected with high duty metal suspension ring 6 on buttonhole selvage 5, and the spacing of adjacent suspension ring 6 is not more than 800mm simultaneously.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
