Abstract
The utility model belongs to the field of coal mine construction safety, and relates to a compression-injection type wind-powered slagging hole packer, which comprises a mounting pipe. An air sac is sleeved on the mounting pipe, the mounting pipe is provided with an air inlet pipe used for supplying air to the air sac, an outer discharge joint is disposed on the mounting pipe, and the mounting pipe is in close fit with a sealing sleeve. The compression-injection type wind-powered slagging hole packer can be applied to loose and soft coal.
Description
Technical field
The utility model belongs to construction safety field, colliery, relates to a kind of press injecting type wind power slag-discharging hole packer.
Background technology
The wind power slag-discharging technology is as present national colliery cherry coal boring or be widely adopted to the basic application technology of coal borer hole construction down.The wind power slag-discharging hole packer is its core technology, has solved use blast row powder, and a large amount of coal dusts that hell is brought fly upward, the situation of severe exacerbation working environment.But utilization for many years, the limitation of this technology also progressively embody, as general third constellations hardness factor less than 0.3 or the coal seam of coal mass relief ravel area in when using, the sealing of hole effect is not lasting, it is serious to leak out, the sealing of hole effect is undesirable.
The utility model content
The technical problems to be solved in the utility model provides a kind of press injecting type wind power slag-discharging hole packer that can be applicable to soft coal body.
Content of the present utility model is that it comprises mounting pipe, and described mounting pipe is set with air bag and is provided with the air inlet pipe that is used for to the air bag air feed; Described mounting pipe is provided with and effluxes joint, tight fit between described mounting pipe and the seal sleeve.
The beneficial effects of the utility model are, the utility model can utilize at any time presses wind to inject, adjust hole packer pressure, comprehensively be adapted to the construction of various hardness coal bed drillings, make the wind power slag-discharging technology be more suitable for loose coal under nature or artificial action state, particularly be suitable for weak seam, projecting coal bed anti-outstanding measure drilling construction, greatly improved the operating environment at wind-force row powder scene, for workman's physical and mental health provides safer, reliable assurance.
Take reliable obturator tight fit between seal sleeve of the present utility model and the mounting pipe steel pipe, the steel pipe brute force of correcting one's mistakes between mounting pipe steel pipe and the aperture sector hole wall thrown into to present on the mounting pipe steel pipe, put a rubber swelling sebific duct, utilize and press the wind gas-flow closure, and in drilling process, when leaking gas in case find aperture section boring rib to become flexible, inject with air inlet pipe snap joint presses wind to replenish the sebific duct seal orifice at once, eliminated the dirt source in these two places, make the dust in the normal drilling process, dregs etc. all can be introduced threeway and enter and efflux joint, and then discharge.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
In the drawings, 1 mounting pipe, 2 air bags, 3 clips, 4 air inlet pipe, 5 seals, 6 efflux joint.
The specific embodiment
Shown in Fig. 1-2, the utility model comprises mounting pipe 1, and described mounting pipe 1 is set with air bag 2 and is provided with the air inlet pipe 4 that is used for to air bag 2 air feed; Described mounting pipe 1 is provided with and effluxes joint 6, tight fit between described mounting pipe 1 and the seal sleeve.
The two ends of air bag 2 are fixed on the mounting pipe 1 by clip 3, make it to form an airtight space, are used for the gap between airtight mounting pipe 1 and the aperture.Be provided with seal 5 between mounting pipe 1 and the seal sleeve, prevent that methane gas and ickings from spilling from this gap.
When the utility model uses, opening bit is installed at first, is started rig when coal body is advanced to certain position, move back brill, change normal Drilling bore bit; The drilling rod that drill bit will be housed then inserts mounting pipe 1, and the mounting pipe 1 of packing into is along with drill bit enters coal body; After mounting pipe 1 put in place, after the aperture gas injection was sealed, rod boring, materials such as dregs came off to enter in the hole from coal body and efflux joint 6 and discharge.
