Description
Technical field
The utility model relates to hole sealing device used on colliery, is specially mining drilling hole packer.
Background technology
Coal mine gas drainage need to be on coal seam drilling, in boring, send into again hole sealing device, existing hole sealing device is the single tube hole packer being comprised of the external valve of monolayer steel pipe, during use, single tube hole packer inserts in boring, then rubber pad is filled in to the gap between single hole hole packer and boring, then after forcing to hammer into timber wedge, by cement mortar, sealed.Because cement mortar setting time is long, and it is poor to solidify rear elasticity, and the impact of vibrating while being subject to drilling construction is easily destroyed, need frequently to repeat sealing of hole operation, and sealing of hole effect is also poor.
Summary of the invention
Existing hole sealing device sealing of hole is not tight, the poor problem of practical function in order to solve for the utility model, and mining drilling hole packer is provided.
The utility model is to adopt following technical scheme to realize: mining drilling hole packer, comprise the slotting inner tube within the outer tube of outer tube and front end, on the rear end body of inner tube, cover has rubber tube, the end, rear end of inner tube is fixed with the first position-limiting tube, the body upper ring cap of the middle-end of inner tube has the second position-limiting tube, the front end of outer tube and inner tube is all provided with flange, and on the flange of inner tube, symmetry has bolt hole, is provided with shank of bolt in bolt hole.
During use, mining drilling hole packer is put into boring, turn the shank of bolt in interior pipe flange upper bolt hole, the end face of shank of bolt withstands on the flange of outer tube, shank of bolt continues to be turned, inner and outer tubes relative sliding, the front end of inner and outer tubes gradually displacement leaves, and afterbody gradually displacement approach, outer tube pushes the second position-limiting tube on the middle-end body of inner tube, the second position-limiting tube pushes rubber tube again, rubber tube lateral length compresses and longitudinal spreading, after the longitudinal spreading of rubber tube, can stop up the gap between hole packer and boring completely, greatly increase again the pressure between hole packer and boring, make hole packer and boring be difficult to relative displacement, reach the object of sealing of hole, the fixing position-limiting tube in end, inner tube rear end plays the effect of restriction rubber tube position on inner pipe, longitudinal spreading when rubber tube is squeezed.
In order to overcome the problems such as existing single tube hole packer sealing of hole is not tight, practical function is poor, operation is inconvenient, the utility model adopts inside and outside two-tube hole packer, utilize compression-expansion principle, transverse compression rubber tube, make it longitudinal dilatation extruding borehole wall, reach the effect of sealing of hole, and simple to operate, sealing quality is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-outer tube, 2-inner tube, 3-rubber tube, 4-the first position-limiting tube, 5-flange, 6-bolt hole, 7-shank of bolt, 8-the second position-limiting tube.
The specific embodiment
Mining drilling hole packer, comprise the slotting inner tube 2 within the outer tube of outer tube 1 and front end, on the rear end body of inner tube 2, cover has rubber tube 3, the end, rear end of inner tube 2 is fixed with the first position-limiting tube 4, the body upper ring cap of the middle-end of inner tube has the second position-limiting tube 8, the front end of outer tube 1 and inner tube 2 is all provided with flange 5, and on the flange of inner tube, symmetry has bolt hole 6, is provided with shank of bolt 7 in bolt hole.
During concrete enforcement, the caliber of position-limiting tube is identical with the caliber of outer tube, shank of bolt length be 200mm.
