Abstract
The invention discloses a telescopic drainage hole sealer which comprises a drainage pipe; wherein, at least two coaxial hole seal pipes are sheathed on the drainage pipe, the drainage pipe is longer than the hole seal pipes, both ends of each hole seal pipe are respectively provided with a closure plate, and a coaxial cylindrical air sac is arranged between the hole seal pipes; the drainage pipe penetrates through and is connected with the closure plate and the air sac through rotation fit, and a holding apparatus outside the closure plates on the ends of the hole seal pipes is arranged on the drainage pipe. The telescopic drainage hole sealer has the advantages of simple structure, easy production and installation and convenient operation, can be suitable for draining or injecting liquid into holes of different hole diameters through the dimension change of the components of the telescopic drainage hole sealer, solves the fault problems of pipeline cracking, ventilation and liquid leakage and even breakage, prolongs the service life of the main device, shortens the working time, increases the working efficiency, reduces the drainage times and the maintenance workload and cost, has high drainage or liquid injection speed, high reusability and easy maintenance, and guarantees the quality and the safety of liquid drainage or injection.
Description
Technical field
The present invention relates to the device on a kind of mine protrusion-dispelling, the anti-integrated system of harnessing the river, relate in particular to a kind ofly be used to draw out methane, the telescopic type pulling hole packer of coal body water filling and grouting for water blocking.
Background technology
In mine construction and manufacturing process, run into projecting coal bed and water-bearing stratum through work planes such as the pit shaft of being everlasting, Da Xiang, chambers.Outstanding in order to prevent and treat coal and gas, the saturating watered-out well in prevention rock stratum, at protrusion-dispelling, anti-concrete condition of harnessing the river, need carry out the extraction coal-bed gas, water filling discharges gas, crosses work such as water guide, grouting for water blocking in the aquifer in the coal seam, to realize Mine Safety in Production, increase work efficiency the generation of preventing accident.At present, the sealing of hole mode that is used for gas drainage under suction, coal body water filling and grouting for water blocking mainly contains two kinds, a kind of is that releasing pipe is inserted in the extraction hole, adopt as yellow mud, cement mortar or chemical material seal around the releasing pipe, this encapsulating method complicated operation, operation is more, sealing quality is not high and the shortage flexibility; The another kind of hole packer that adopts, though have hole-sealing technology simple, quick, advantage such as can reuse, but also have following defective: the price height, fragile, the drilling quality of sealing of hole section is had relatively high expectations, require boring not have distortion, do not have and subside, and plugging effect is bad, imprecision, perhaps the better later stage of initial stage shutoff is relatively poor etc.
Summary of the invention
The present invention is in order to solve weak point of the prior art, and a kind of simple in structure, easy to use, high efficiency, cost is low, safe and reliable, plugging effect is good telescopic type pulling hole packer are provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: telescopic type pulling hole packer, comprise releasing pipe, described releasing pipe outer cover is provided with coaxial hole sealing tube, and releasing pipe is greater than hole sealing tube length, and hole sealing tube is provided with two at least, the hole sealing tube two ends are equipped with closure plate, be provided with coaxial cylindrical air bag between the hole sealing tube, releasing pipe penetrates closure plate, air bag and is connected with its rotation, and the closure plate outside of hole sealing tube termination is provided with hold down gag in releasing pipe.
Described hold down gag comprises the nut that is spirally connected with releasing pipe, and thrust bearing is installed on releasing pipe between the closure plate that nut and its close on.
Radially be provided with the pin that protrudes from the hole sealing tube outer wall on the described releasing pipe.
Coaxial plain cushion is installed on releasing pipe in the described air bag.
Be provided with the coaxial circular baffle plate that is fixed with of an end of hold down gag on the described releasing pipe relatively, between baffle plate and its hole sealing tube that closes on, be provided with cylindrical air bag on the releasing pipe, in this air bag coaxial plain cushion is installed on releasing pipe, this air bag is consistent with the hole sealing tube outside dimension with baffle plate.
Adopt said structure, inject the operation hold down gag, the closure plate extruding cylindrical air bag therebetween of hole sealing tube end, air bag expanded radially and extraction or water filling, injected hole closely cooperate, and reach the purpose of tight sealing of hole; Hold down gag adopts nut and thrust bearing, and simple in structure, easy and simple to handle, the degree of compressing can progressively advance, and reaches better sealing effectiveness; Pin can play with the wrench operated nut time, prevents that releasing pipe and nut from rotating simultaneously; Plain cushion can prevent cylindrical air bag compression excessively, plays cushioning effect; An end that is provided with hold down gag on the releasing pipe relatively is provided with circular baffle plate, air bag and plain cushion, and such setting can strengthen the tight ness rating of sealing of hole; The present invention is simple in structure, manufacturing simple installation, easy to operate, can be by the change of self component and fitting size, be fit to the extraction or the fluid injection of different aperture sizes, solved the pipeline crackle, leaked out, the failure problems of leakage even fracture, when prolonging the agent set life-span, shortened the working time, improved operating efficiency, reduced the extraction number of times, reduced maintenance workload and cost, extraction or fluid injection speed are fast, the reusability height, be easy to safeguard, guaranteed the quality and safety of extraction or fluid injection.
