Abstract
The utility model discloses a banded inflatable hole sealing device is taken out in colliery gas drainage. The two ends of a strip-shaped inflatable adhesive tape (5) are provided with tying openings (9), the two tying openings (9) are tightly pressed at the two ends of a drawing and releasing pipe (2) by baffle discs (3), an open-type locking ring (8) is fastened at the outer end of the baffle disc (3) by bolts and fastens the two tying openings (9), the strip-shaped inflatable adhesive tape (5) is arranged between the two baffle discs (3), and is sealed in a rock drilling hole (1) after being inflated, an inflation tube (6) is fixedly arranged at the right lower end of the strip-shaped inflatable adhesive tape (5), and an inflation nozzle (7) is arranged at the right end of the inflation tube (6). Because the utility model discloses a banded inflatable sticky tape can carry out the hole sealing to the hole sealing of 6-8 meters, and the hole sealing is long, and the hole sealing is effectual, repeatedly usable, and the staff when periodic detection drilling gas concentration, carries out the tonifying qi to the mining pressure fan that the drilling that takes out the concentration reduction is available to improve the utilization ratio of hole sealing efficiency and gas by a wide margin, the energy saving.
Description
The technical field is as follows:
the utility model relates to a colliery is taken out and is adopted banded inflatable hole sealing device with gas that uses when gas is taken out and put in colliery.
Background art:
at present, the hole is drilled by pumping and discharging gas in the underground coal mine, one-time hole sealing is adopted, and the hole sealing material cost is very high. When gas is drained, the inside of the drill hole is likely to have the phenomena of hole collapse and the like, so that the gas cannot be drained from the drainage drill hole, the drill hole needs to be repaired, and the repair work cannot be carried out by adopting the drill hole with the one-time grouting hole sealing process. And adopt current interim hole sealing device, the hole sealing effect is poor, makes the gas drainage concentration not guarantee, and the gas can not utilize, causes extravagant and polluted environment.
The utility model has the following contents:
the utility model aims to solve the technical problem that an adopt banding inflatable sticky tape can carry out the hole sealing to 6-8 meters hole sealing, and the hole sealing is long, and the hole sealing is effectual, and the staff is when periodic detection drilling gas concentration, and the available mining pressure fan of drilling to taking out the reduction of drainage concentration carries out the tonifying qi to improve the banding inflatable sealing device of gas drainage for the colliery of hole sealing efficiency by a wide margin.
The utility model provides a technical scheme that technical problem adopted is: the two ends of a belt-shaped inflatable adhesive tape of the gas extraction belt-shaped inflatable hole sealing device for the coal mine are provided with beam openings, two beam openings are tightly pressed at the two ends of the extraction pipe by baffle discs, an open-type locking ring is fastened at the outer end of each baffle disc by bolts and fastens the two beam openings, the belt-shaped inflatable adhesive tape is arranged between the two baffle discs and sealed in a rock drill hole after being inflated, an inflation pipe is fixedly arranged at the right lower end of the belt-shaped inflatable adhesive tape, and an inflation nozzle is arranged at the right end of the inflation pipe.
The utility model has the advantages that: due to the fact that the strip-shaped inflatable adhesive tape is adopted, hole sealing can be conducted on 6-8 m of holes, the hole sealing is long, the hole sealing effect is good, and when workers detect the gas concentration of the drill hole regularly, the mining pressure fan used for mining and used for the drill hole with the reduced extraction concentration can be used for supplying gas, so that the hole sealing efficiency and the gas utilization rate are greatly improved, and energy is saved.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a right side view of fig. 1.
The specific implementation mode is as follows:
example 1: as shown in fig. 1 and 2, two ends of a belt-shaped inflatable adhesive tape 5 of the belt-shaped inflatable hole sealing device for coal mine gas extraction are provided with a tying opening 9, two tying openings 9 are tightly pressed at two ends of a drawing and releasing pipe 2 by baffle discs 3, an open type locking ring 8 is fastened at the outer end of the baffle disc 3 by bolts and fastens the two tying openings 9, the belt-shaped inflatable adhesive tape 5 is arranged between the two baffle discs 3 and sealed in a rock drill hole 1 after being inflated, an inflation pipe 6 is fixedly arranged at the right lower end of the belt-shaped inflatable adhesive tape 5, and an inflation nozzle 7 is arranged at the right end of the inflation pipe 6.
Example 2: as shown in fig. 1 and 2, a gas extraction inner hole 4 is arranged in a drainage pipe 2 of the gas extraction strip-shaped inflatable hole sealing device for coal mines.
Example 3: as shown in fig. 1 and 2, the right end of the drainage pipe 2 of the gas extraction banded inflatable hole sealing device for coal mines is connected with a gas drainage pump, and the outer end of the inflating nozzle 7 is connected with an inflating pump.
Example 4: as shown in fig. 1 and 2, the strip-shaped inflatable adhesive tape 5 of the coal mine gas extraction strip-shaped inflatable hole sealing device is made of rubber, and the baffle disc 3 is made of a soft material.
Example 5: as shown in fig. 1 and 2, when the gas extraction strip-shaped inflatable hole sealing device for coal mines is used for an extraction borehole which needs to be repaired and a through hole, the hole sealing device can be taken out only by deflating the hole sealing device, and the hole sealing device is inflated again after the borehole is repaired.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
