Description
Technical field
The utility model is related to the mechanical equipment in colliery field, more particularly to a kind of brill for coal seam pipe laying to be taken out
Machine drill has and uses its drilling machine.
Background technology
As shown in Figure 1, coal mine gas is administered because requirement of engineering is, it is necessary in coal wall, wall (top plate, bottom plate)
The drilling of brill different-diameter, different depth, the tubing 1 ' and periphery that certain length is embedded to inside drilling use cement mortar
Or polyurethane material 2 ' is filled sealing, for the gas inside extraction coal bed drilling, prevents Gas Outburst hidden danger, ensures
Mining production safety.
Currently, the gas drainage under suction tubing that colliery uses is typically all metal or fire-retardant organic tubing, sealing of hole seal length
Generally 15 meters, extraction tubing is all stayed in coal wall substantially after the completion of gas drainage under suction task, and wherein organic tubing is to subsequent
Mechanical coal mining equipment influences less, but is trapped in the operation that the metal pipe material in coal wall seriously affects coalcutter, when
Since metal bump may cause spark when coalcutter runs to the region, security risk is very big；Second is that metal tube may be made
Into the damage of coal winning machine cutting bit.
Now, the gas drainage pipe that colliery uses in coal seam is largely organic material, but because the anti-reflection need of gas
The new technology wanted, such as the techniques such as coal bed fracturing is anti-reflection, coal seam high pressure water injection, since hydraulic pressure is very high, it is necessary to use metal pipe material
High pressure water injection is carried out, the pressure break pipe uses again as gas drainage pipeline after the completion of pressure break, since sealed borehole length all reaches substantially
To more than 30 meters, after engineering has carried out, pressure break metal tube can not possibly be extracted out, and certain obstacle and hidden danger are brought to follow-up coal mining,
Therefore metal tube therefrom can be smoothly taken out necessary.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of coals that can smoothly take out the metal tube in coal seam
Layer pipe laying takes out drilling machine drilling tool and uses its drilling machine.
Coal seam pipe laying in the utility model takes out drilling machine drilling tool, and including drilling rod and drill bit, the drilling rod and drill bit are in
Tubular structure, the outer wall of described drilling rod one end are equipped with external screw thread, and the inner wall of the drilling rod other end is equipped with internal thread, described
The outer wall of drill bit one end is equipped with external screw thread, and the drill bit other end end is fixed with blade, and the drill bit passes through on itself
External screw thread be connected with the internal thread on the drilling rod.
Coal seam pipe laying in the utility model takes out drilling machine drilling tool, wherein the blade is carbide chip, the knife
Piece is fixed on the end of the drill bit by welding.
Coal seam pipe laying in the utility model takes out drilling machine drilling tool, wherein the quantity of the blade is set to more than 2, it is described
Blade is evenly arranged centered on the axis of the drill bit.
Drilling machine in the utility model, including drilling tool, the drilling tool takes out drilling machine drilling tool for above-mentioned coal seam pipe laying.
The utility model coal seam pipe laying takes out drilling machine drilling tool and is this using its drilling machine difference from prior art
Drilling rod and drill bit in utility model are tubular structure, and drilling rod and drill bit are fixed together, and hollow drill is according to coal seam
In steel pipe sizes select suitable size, drill bit and drill rod sleeve rotates outside steel pipe and water flowing (or ventilation) cools down chip removal,
What it is due to drill bit cutting is the cement mortar of steel pipe or polyurethane sealing Porous materials, and drilling depth only has 30 meters or so, work
The drilling machine torque needed is little；After hollow boring bit all drills out the sealing material in sealed borehole length, drilling rod is retracted, at this moment,
Steel pipe is a free state in coal wall, and the mechanical jack used using lifting, which ties down steel pipe head, to pull out coal steel pipe
Wall, it is convenient and practical.
The utility model is described in further detail below in conjunction with the accompanying drawings.

Specific embodiment
As shown in Fig. 2, and with reference to shown in Fig. 3,4, the coal seam pipe laying in the utility model takes out drilling machine drilling tool, including drilling rod
3 and drill bit 4, the drilling rod 3 and drill bit 4 are cylindrical in shape structure, and the outer wall of described 3 one end of drilling rod is equipped with external screw thread, the brill
The inner wall of 3 other end of bar is equipped with internal thread, and the outer wall of described 4 one end of drill bit is equipped with external screw thread, 4 other end end of drill bit
Portion is fixed with blade 5, and the drill bit 4 is connected by the external screw thread on itself with the internal thread on the drilling rod 3.
Coal seam pipe laying in the utility model takes out drilling machine drilling tool, wherein the blade 5 is carbide chip, the knife
Piece 5 is fixed on the end of the drill bit 4 by welding.
