Fig. 3 is the sectional view of line B-B along Fig. 1.

With reference to specific embodiments and the drawings, the utility model is described in further detail.

Specific embodiment

As shown in Fig. 1, Fig. 2 and Fig. 3, a kind of mining inflating air pile device includes gas centipede space 1, the shape of the gas centipede space 1 In cuboid-type, gas centipede space 1 includes bladder layer 1, bladder layer 23, shell 1 and shell 25, and bladder layer 1 is cuboid Shape, bladder layer 1 are internally formed inner bag 1, and its effect is to make 1 basic forming of gas centipede space, set on the leading flank of gas centipede space 1 There are inner bag charge valve 1 and inner bag charge valve 27, safety valve is provided between one 6 gentle centipede space 1 of inner bag charge valve and (is not shown in figure Go out), the periphery of 1 leading flank of gas centipede space is provided with edge sealing 8, and edge sealing 8 is rectangle, and edge sealing 8 is provided with some suspension ring 9；Bladder layer 23 is Hollow annular, bladder layer 23 are sheathed on the outside of the top of bladder layer 1, bottom, bladder layer 1 at two sides in left and right, Bladder layer 23 is internally formed inner bag 2 11, and the effect of inner bag 2 11 is the plugging effect in order to improve gas centipede space 1, bladder layer Be provided with shell 1 between 23 and bladder layer 1, the effect of shell 1 be in order to protect bladder layer 1 and bladder layer 23 not by Damage, shell 25 be wrapped in the outside of bladder layer 23 and former and later two sides of gas centipede space 1 at bladder layer 1 outside, plus The specification of the gas centipede space 1 of work is long 1800mm, a width of 800mm, a height of 800mm.

The bladder layer 1 of the gas centipede space 1 and bladder layer 23 are by flame-retardant and anti-static and the very big rubber system of elongation percentage Make into the plastic coat cloth of, shell 1 and shell 25 by flame-retardant and anti-static, impact resistance, the plastic coated fabric is adopted It is framework material with aramid fabric, with plastic hybrid as coat.

During the utility model use, using front, a preset value is set to the gas pressure in gas centipede space 1, this presets Be worth flexible gas pressure limiting value is kept for gas centipede space 1.During use, the utility model is put in coal work in unaerated The bottom in face, is fixed on gas pile on the side wall of working face by cable traction suspension ring 9, then by the source of the gas of coal-face with The inner bag charge valve 1 of gas pile is connected, and inflates to the inner bag 1 of gas pile, closes source of the gas, make before gas centipede space 1 reaches rigidity Gas pile keeps flexible.When the pressure in gas centipede space 1 exceedes preset value, the safety valve automatic deflation, when inflation in gas centipede space 1 When being in excessively rigid state, open the safety valve and deflate, gas centipede space 1 is made in flexibility.Afterwards by source of the gas and the inner bag of gas pile Charge valve 27 is connected, and gives the inner bag 2 11 appropriate inflation.Due to the presence of the inner bag 2 11, the top of gas pile, bottom And two sides in left and right can according to the shape of working face upper and lower corner the shape of adjust automatically itself, to reach and upper and lower corner The state for matching, and keep this shape.

Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New scope is defined, and on the premise of without departing from the utility model design spirit, those of ordinary skill in the art are to this Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of the utility model claims determination In the range of.
