Abstract
A mining flexible inflatable air bag comprises an air bag body, an air inlet valve is arranged on the front side face of the air bag body which is made of easily shaped materials, the volume of the air bag body is matched with the size of a plugged roadway, and a safety valve is further arranged on the front side face of the air bag body. When pressure in the air bag body exceeds a limit value enabling the air bag body to keep flexible, the air bag body can be deflated by the safety valve so as to keep flexible. By the aid of the safety valve arranged on the air bag body and enabling the air bag body to keep flexible, the air bag body can be adjusted in shape according to the shape of a plugged position so as to be matched with the plugged position, and plugging effect is better.
Description
Technical field
The utility model relates to the safety device in a kind of mine or the tunnel, relates to specifically a kind of expandable safety device.
Background technology
Under the coal mine on the coal-face, the filling of lower corner, usually adopt manually the rear filling of coalingging in the woven bag, because single woven bag obturation out-of-shape, poor plasticity, can not fit tightly between each obturation, there is the slit, outwards gush out from the slit for preventing gas, also need use the soft material pay the seam, filling effect is poor, efficient is low, filling cost is higher, and the shutoff that the woven bag after coalingging forms is irremovable, in whole operation process, this shutoff work repeating again and again, not only take a lot of work, take material, workman's labour intensity is also very large, and because of loading time long, filling and work plane coal cutting can not parallel operations, greatly limited the performance of working surface production ability.The patent No. is that the Chinese utility model patent of 200720038860.X discloses a kind of movable coal mine fully-mechanized mining working faces end head plugging air bag for safety, this air bag can replace the Coal sack shutoff, shutoff is more reliable, efficient is higher, reusable, reduced workman's labour intensity, but this air bag pouch is soft material, inflation makes its pier shape that reaches rigid state could realize shutoff in pouch, in the shutoff process pier shape pouch of rigidity can't with by the tunnel sidewall of shutoff, top board coincide, plugging effect is relatively poor, even the top in pouch, both sides arrange inflatable fold, also can't with fitted like a glove by the tunnel of shutoff.
The utility model content
The purpose of this utility model provides a kind of mining flexible gas-filled air bag, and its shape can be according to being adjusted by the shape of block-up position and keep this shape after adjustment, with better by the shutoff place shape goodness of fit, plugging effect is better, and the scope of application is wider.
To achieve these goals, technical solution of the present utility model is: a kind of mining flexible gas-filled air bag, comprise pneumatophore, the leading flank of pneumatophore is provided with admission valve, described pneumatophore is easy shaping material, and the tunnel size of the volume of pneumatophore and institute's shutoff adapts, and also is provided with safety valve on the leading flank of described pneumatophore, when the pressure in the described pneumatophore surpasses the limiting value that makes described pneumatophore keep flexibility, can make pneumatophore keep flexible by the safety valve venting.
The utility model is mining flexible gas-filled air bag, wherein, described pneumatophore comprises internal layer, the skin of stack, described inside and outside layer all adopts the flexiplast coated cloth to make.
The utility model is mining flexible gas-filled air bag, wherein, described flexiplast coated cloth is the coal rock tunnel BP-2 type flexiplast coated cloth that du pont company is produced.
The utility model is mining flexible gas-filled air bag, wherein, the periphery of described pneumatophore is provided with the wind limit, the wind limit is near pneumatophore) the leading flank setting, the wind limit is provided with several suspension ring.
After adopting such scheme, the utility model is mining, and the flexible gas-filled air bag makes it keep flexible because pneumatophore is provided with safety valve, so pneumatophore can be according to by the shape adjustments of block-up position self shape, with matched by shutoff place, plugging effect is better.
In addition, the ectonexine of pneumatophore all adopts the flexiplast coated cloth to make, fire-retardant, antistatic, the characteristics such as windage is little, intensity is high, the blast-proof ability is strong, ageing-resistant, the use permanent, quality is light, easy to break, easy typing that the flexiplast coated cloth has, further improve plugging effect, and make the mining flexible gas-filled air bag of the utility model scope of application wider, not only can be used for the up and down corners shutoff, also can be used for airtight under the coal mine, hollow and fill and top braces, or construct within the specific limits fire wall.Separate, non-caked between the inside and outside layer of pneumatophore in addition; pressure Main Function in the pneumatophore is protected skin at internal layer, and the suffered external impacts Main Function of pneumatophore is in skin; internal layer is protected, thereby prolongs the application life of mining flexible gas-filled air bag.
Description of drawings
Fig. 1 is the front view of the mining flexible gas-filled air bag of the utility model;
Fig. 2 is the left view of the mining flexible gas-filled air bag of the utility model.
Specify the mining flexible gas-filled air bag of the utility model below in conjunction with accompanying drawing.
The specific embodiment
Such as Fig. 1, shown in 2, the utility model is mining, and the flexible gas-filled air bag comprises pneumatophore 1 and wind limit 2, the size in the tunnel of the volume of pneumatophore 1 and institute's shutoff adapts, the leading flank of pneumatophore 1 is provided with admission valve 11 and safety valve 12, pneumatophore 1 comprises internal layer and the skin of stack, in, skin all adopts the flexiplast coated cloth to make, the coal rock tunnel BP-2 type flexiplast coated cloth that the flexiplast coated cloth adopts du pont company to produce, it adopts high strength synthetic fibre as framework material, take plastic hybrid as coat, in the pneumatophore 1, outer separate, be nested together, pneumatophore 1 periphery is located on wind limit 2, and wind limit 2 is near the leading flank of pneumatophore 1, and wind limit 2 is provided with a plurality of suspension ring 21.
During use, the mining flexible gas-filled air bag of the utility model is put in the upper of coal-face when the unaerated, lower corner, fix by suspension ring and sidewall, then the source of the gas with coal-face is connected with admission valve 11, make pneumatophore 1 inflation, pneumatophore 1 interior pressure is no more than closes source of the gas before 0.3MPa reaches rigidity, make air bag keep flexible, when pneumatophore 1 internal pressure surpasses preset limit value 0.5MPa, for preventing pneumatophore 1 explosion, safety valve 12 automatic deflations, when pneumatophore 1 interior inflation too much was rigid state, 12 venting opened the safety-valve, make pneumatophore 1 be flexible, according to upper, the shape of the shape adjustments pneumatophore 1 of lower corner matches pneumatophore shape 1 and corner up and down, and keeps this shape.
The inside and outside layer of the utility model is mining flexible gas-filled air bag pneumatophore 1 adopts the flexiplast coated cloth to make, the hot strength of its inside and outside layer is 3-5 times of steel, long service life, and have fire-retardant, antistatic, the characteristics such as windage is little, intensity is high, the blast-proof ability is strong, ageing-resistant, the use permanent, quality is light, easy to break, easy typing, therefore the mining flexible gas-filled air bag of the utility model also can be used for airtight under the coal mine, hollow and fills and top braces, or construct within the specific limits fire wall.
The above embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
