Abstract
The invention discloses a mining flexible inflatable air bag comprising an air bag body; the front side surface of the air bag body is provided with an air intake valve; the air bag body is made of easily shaped materials; the volume of the air bag body adapts to the size of a roadway to be plugged; the front side surface of the air bag is also provided with a safety valve; and the air bag body is kept flexible by the safety valve when the pressure in the air body is higher than a limit value of keeping the air bag flexible. The mining flexible inflatable air bag is provided with the safety valve on the air bag body so as to keep the air bag body flexible, so that the air bag body can adjust the own shape according to the shape of the place to be plugged so as to be identical to the place to be plugged, so that the plugging effect is good.
Description
Technical field
The present invention relates to the safety device in a kind of mine or the tunnel, relate to a kind of expandable safety device specifically.
Background technology
The filling of the upper and lower corner of coal-face under the coal mine is adopted the artificial back filling of in woven bag, coalingging, usually owing to single woven bag obturation out-of-shape, poor plasticity; Can not fit tightly between each obturation, have the slit, from the slit, outwards gush out for preventing gas; Also need use the soft material pay the seam, filling effect is poor, efficient is low, and filling cost is higher; And the shutoff that the woven bag after coalingging forms is not removable, in the entire job process, and this shutoff work repeating again and again; Not only take a lot of work, take material, working strength of workers is also very big, 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, and shutoff is more reliable, efficient is higher, reusable, has reduced working strength of workers; But this air bag capsule bag is a soft material; Inflation makes its pier shape that reaches rigid state could realize shutoff in the capsule bag, and the pier shape capsule bag of rigidity can't be with identical by the tunnel sidewall of shutoff, top board in the shutoff process, and plugging effect is relatively poor; Even top, both sides at the capsule bag are provided with inflatable fold, also can't with fitted like a glove by the tunnel of shutoff.
Summary of the invention
The purpose of this invention is to provide a kind of mining flexible air bag, its shape can be according to being adjusted by the shape of block-up position and after adjustment, keep this shape, 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 invention is: a kind of mining flexible air bag comprises pneumatophore; The leading flank of pneumatophore is provided with admission valve; Said pneumatophore is for being prone to 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 said pneumatophore; When the pressure in the said pneumatophore surpasses the limiting value that makes said pneumatophore keep flexibility, can make pneumatophore keep flexible through the safety valve venting.
The present invention is mining flexible air bag, wherein, said pneumatophore comprises internal layer, the skin of stack, said inside and outside layer all adopts the flexiplast coated cloth to process.
The present invention is mining flexible air bag, wherein, said flexiplast coated cloth is the coal rock tunnel BP-2 type flexiplast coated cloth that du pont company is produced.
The present invention is mining flexible air bag, wherein, the periphery of said 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 present invention is mining, and flexible air bag makes it keep flexible because pneumatophore is provided with safety valve, so pneumatophore can be according to by the Adjusting Shape 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 process; Fire-retardant, antistatic, characteristics such as windage is little, intensity is high, the blast-proof ability is strong, ageing-resistant, it is permanent to use, light weight, easy to break, easy typing that the flexiplast coated cloth has; Further improve plugging effect, and make the mining flexible air bag scope of application of the present invention wider, not only can be used for upper and lower corner shutoff; Also can be used for airtight under the coal mine, hollow and fill and top braces, or construct fire wall within the specific limits.Separate, non-caked between the inside and outside layer of pneumatophore in addition; Pressure in the pneumatophore mainly acts on internal layer, and skin is protected, and the suffered external impacts of pneumatophore mainly acts on skin; Internal layer is protected, thereby prolongs the application life of mining flexible air bag.
Description of drawings
Fig. 1 is the front view of the mining flexible air bag of the present invention;
Fig. 2 is the left view of the mining flexible air bag of the present invention.
Specify the mining flexible air bag of the present invention below in conjunction with accompanying drawing.
The specific embodiment
Like Fig. 1, shown in 2, the present invention is mining, and flexible air bag comprises pneumatophore 1 and wind limit 2, and 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, and pneumatophore 1 comprises the internal layer and the skin of stack, and inside and outside layer all adopts the flexiplast coated cloth to process; 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, is coat with the plastic hybrid, and the inside and outside layer of pneumatophore 1 is 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 air bag of the present invention is put in the upper and lower corner of coal-face when the unaerated, fixes through suspension ring and sidewall; Source of the gas with coal-face is connected with admission valve 11 then, makes pneumatophore 1 inflation, and pressure is no more than and closes source of the gas before 0.3MPa reaches rigidity in the pneumatophore 1; 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 inflation too much was rigid state in the pneumatophore 1,12 venting opened the safety-valve; Make pneumatophore 1 be flexible; According to the shape of the Adjusting Shape pneumatophore 1 of upper and lower corner, pneumatophore shape 1 and corner are up and down matched, and keep this shape.
The inside and outside layer of the present invention is mining flexible air bag pneumatophore 1 adopts the flexiplast coated cloth to process; The hot strength of its inside and outside layer is 3-5 a times of steel; Long service life; And have fire-retardant, antistatic, windage is little, intensity is high, the blast-proof ability is strong, ageing-resistant, use permanent, light weight, easy to break, be prone to characteristics such as typing, so the mining flexible air bag of the present invention also can be used for airtight under the coal mine, hollow filling and top braces, or constructs fire wall within the specific limits.
The above embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that the common engineers and technicians in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
