Description
Technical field
The present invention designs a kind of colliery drilling safety frock, especially a kind of spy boring blowout hookup that discharges water.
Background technology
As everyone knows, drilling rod ejects and sprays water and all has potential safety hazard in colliery construction.But, the safe frock of constructing under the present coal mine can only play the function that prevents that drilling rod from ejecting, and does not have drain function, therefore, design a kind of have simultaneously prevent that drilling rod from ejecting spy with the drain function boring blowout hookup that discharges water, be the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provide a kind of have simultaneously prevent that drilling rod from ejecting spy with the drain function boring blowout hookup that discharges water.
The technical scheme that the present invention solves its technical problem is:
The spy boring blowout hookup that discharges water, be useful on the lower flange that is connected with fixing borehole wall sleeve pipe in the bottom of cylinder barrel shaped housing, lower flange has inward flange, upper flange plate is arranged at the top of housing, there is inward flange at the middle part of housing, be set with "T"-shaped differential on the top of housing, "T"-shaped differential is connected with the upper flange plate of housing by bolt, "T"-shaped differential, the internal diameter of the inward flange at housing middle part and the inward flange of lower flange all is slightly larger than the diameter of drilling rod, housing wall below the inward flange at housing middle part is arranged with screwed hole, in screwed hole, be installed with jackscrew, inner head at jackscrew is equipped with slips, housing wall below the inward flange at housing middle part is provided with the gutter that has pipe valve that is communicated with the shell chamber, be filled with encapsulant in inward flange in the middle part of housing and the cavity between the differential, housing and encapsulant pressure-bearing are not less than 10Mpa.
As a preferred embodiment of the present invention, between the inward flange at differential bottom and housing middle part, two platens are set, encapsulant is arranged between two platens.
As a preferred embodiment of the present invention, described encapsulant is some sealing rings that stack layer.
As a preferred embodiment of the present invention, described cylinder barrel shaped housing is that the boundary divides two parts up and down with the inward flange at middle part, and the diameter on top is less than the diameter of lower part.
As a preferred embodiment of the present invention, described differential is the split left and right structure, and left half differential is fluted on the bonding surface at flange place, and the bonding surface of right half differential at the flange place has the projection that matches.
As a preferred embodiment of the present invention, the inner walls of the top and the bottom of slips is provided with the slips guide strip.
As a preferred embodiment of the present invention, the rear of described jackscrew is feed rod, is provided with the jackscrew sealing device at the outer wall of housing.
Operating principle of the present invention:
During operate as normal, bolt 7 does not screw, and encapsulant does not closely contact with drilling rod, when the water ejection is arranged in the boring, at first inwardly twist jackscrew, make slips clamp drilling rod, prevent that drilling rod from ejecting, tight a bolt 7 simultaneously, make encapsulant be close to drilling rod, open pipe valve 13 then rapidly, the anti-spraying effect is played in the precipitation drainage.
Compared with prior art, the present invention has simultaneously that the drilling rod of preventing ejects and drain function.
