Abstract
The utility model aims at providing an irregular air tunnel comprising an air tunnel body manufactured by coating rubber or plastics onto cloth materials. Hanging rings and hanging ring installation lines are equidistantly arranged on the air tunnel body, end ring connectors are arranged on two end heads in the length direction of the air tunnel body, and reverse edges are wrapped at two ends of the air tunnel body. The irregular air tunnel is suitable for fresh air conveying and venting in complex environments including coal mines, tunnels, the underground and caves, has the advantages of being strong in practicality, accurate in installation and positioning and reasonable in structure and improving air guide effect, is high in flame resistance and cold resistance, antistatic, anti-aging, not apt to fracture, free of breakage or crack, long in service life, capable of being used repeatedly, high in safety and suitable for being popularized and used, and reduces production cost.
Description
Technical field
The utility model relates to the colliery apparatus, specifically is a kind of special-shaped air duct.
Background technology
The abnormity air duct has ventilation safety apparatus indispensable in the Safety of Coal Mine Production as ventilation equipment under the coal mine, and its predominant use is and the supporting use of secondary fan; Carry fresh distinguished and admirablely to operation places such as colliery, tunnel, down-hole, caverns, have the wind-guiding effect, but air duct places the top, tunnel to receive the impact damage of slungshot easily; Air duct more often adopts flange or the design of vinyl chloride material in the present technology; Its technology is loaded down with trivial details, and resistance is big, and rate variance leaks out; Installing and locating is not accurate, influences ventilation effect.
The utility model content
The utility model purpose provides a kind of special-shaped air duct, and its installing and locating is more accurate, and is rational in infrastructure, improves wind effect.
In order to realize the utility model purpose; Adopt following technical scheme: the air duct body that comprises the coated cloth material; Equidistant suspension ring and the suspension ring hookup wire of being provided with on the said air duct body, along the two ends configuration end circle joint of air duct body length direction, anti-limit is all wrapped up at the cylindrical shell two ends.
The technical scheme that further adopts is: distance is not more than 800 mm between the said suspension ring.
Said end loop material is that carbon spring steel wires is made.
The suspension ring of termination are not more than 200mm apart from end circle position.
Suspension ring installation torsional capacity is per ten meters and is no more than 1/16 of air duct circumference.
Air duct body coated cloth material according to demand can select for use rubber or plastic production all can, the system coated cloth thickness be not more than 0.80mm.
The utility model is applicable to fresh air conveying and the ventilation under the various complicated such as colliery, tunnel, down-hole, cavern, can make the special-shaped air duct that adapts with it according to its different tunnel, and is fit to any multi-angle installing and locating.
The beneficial effect of the utility model is: simple in structure, with low cost, of many uses; Practical, the special-shaped air duct of the utility model has the anti-flammability height, cold tolerance is high, and is antistatic; Anti-aging, frangible does not have and loses and slight crack, long service life can be used repeatedly, and is safe; Reduce production costs suitable promoting the use of.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Be labeled as 1 air duct body, 2 suspension ring, 3 suspension ring hookup wires, 4 end circles, 5 anti-limits among the figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done further elaboration:
Comprise air duct body 1 among the figure by the coated cloth material, equidistant suspension ring 2 and the suspension ring hookup wire 3 of being provided with on the said air duct body 1, along two ends configuration end circle 4 joints of cylindrical shell length direction, anti-limit 5 is all wrapped up at air duct body 1 two ends, and air duct body 1 barrel dliameter is not more than 1200mm.Distance is not more than 800 mm between the said suspension ring 2.Said end circle 4 materials are that carbon spring steel wires is made.The suspension ring 2 of termination are not more than 200mm apart from end circle 4 positions.Suspension ring 2 installation torsional capacities are per ten meters and are no more than 1/16 of air duct circumference.Air duct body coated cloth material can select for use rubber or plastic production all can, the system coated cloth thickness be not more than 0.80mm.The utility model does not detail part and is known technology, and common variation that those skilled in the art carries out in the utility model technical scheme scope or replacement all should be included in the protection domain of the utility model.
