Abstract
The invention discloses a drill rod linear driller for mine gas drainage under suction and an operation method of the drill rod linear driller. The drill rod linear driller is characterized in that: 4-8 pairs of alloy steel bars are uniformly welded on a cylindrical body with a central hole at intervals in the longitudinal direction; a plurality of alloy blocks which are welded in front of each alloy steel bar at intervals in the longitudinal direction by taking the screwing-in direction of a drill rod as a forwarding direction; the alloy blocks are clung to the respective corresponding alloy steel bars; two ends of the cylindrical body are respectively provided with an inner thread and an outer thread which are matched with the drill rod; and the whole outer diameter of the driller is less than the diameter of a drill head during hole drilling. The drill rod linear driller disclosed by the invention can effectively ensure linear drilling of a common drilling machine during long-distance hole drilling in the construction process. The drill rod linear driller has the advantages of simple structure, less investment and good hole drilling effect. Proved by actual production and use, the drill rod linear driller has very good effect.
Description
Technical field
The present invention relates to a kind of auxiliary accessories of rig.
Background technology
In highly gassy mine or gas emphasis district, generally adopt the boring extraction at present, reach the purpose of administering gas or utilizing gas.When construction drill, if construction length surpasses 100 meters, add the variation of lithology, boring always bends, and can not keep straight line to creep into, and has had a strong impact on the extraction effect.
CN201714317U (CN201020154740.8) provides a kind of down-the-hole drilling tool centralizer; Relate to the construction equipment that a kind of auxiliary down-hole percussion drill tool is set upright guiding, improved borehole throw; Form by centralizer main body and adjustment ring; The centralizer main body is installed between drilling rod and the drill bit, and the adjustment ring is installed on the drilling rod; The centralizer main body is provided with a plurality of supporters with the circumference of adjustment ring, and the deep trouth between the supporter forms channel of chip removal.Because adjustment ring is little with the contact area of drill hole wall, thus can only be applied in harder rock stratum, beat hidden hole drilling, and softer owing to the coal seam when in the coal seam, boring firedamp taking-out discharging drilling, be not enough to support the lateral force of boring, so do not have the effect of setting upright.
Therefore, at present for common rig, also there is not a kind of long device that creeps into apart from straight line that keeps.
Summary of the invention
Drilling rod straight line when the present invention provides a kind of ability to keep common rig to hole creeps into device, can be used for the mine gas drainage drilling construction.
The term explanation
Boring extraction: as the passage that draws out methane, draw out methane construction drill in coal seam or rock stratum.
Technical scheme of the present invention is following:
A kind of drilling rod straight line creeps into device; It is on a cylinder that has a centre bore, longitudinally evenly to weld 4-8 to the alloy steel bar at interval; With drilling rod precession direction is direction of advance, and a plurality of alloy blocks in the longitudinal separation welding before every alloy steel bar require alloy block to be close to and own corresponding alloy steel bar; The cylinder two ends are respectively equipped with internal thread and the external screw thread suitable with drilling rod, and the entire outer diameter of creeping into device is less than the diameter of drill bit when holing.
Preferred according to the present invention, high 50-70 centimetre of said cylinder scapus; Center-hole diameter is 1-2 centimetre,
2-4 centimetre of described alloy block length, wide 1-2 centimetre, thick 1-1.5 centimetre.
The present invention is used for the connection between drilling rod, and is big with the contact area of coal bed drilling wall because it is a cylindricality, can guarantee effectively that the straight line of common rig when the long distance of construction is holed creeps into.This apparatus structure is simple, small investment, and it is effective to drill, and uses proving effect very good through actual production.
Description of drawings
Fig. 1 is that the master that the present invention creeps into device looks sketch map;
Among the figure: 1-internal thread, the cylinder of 2-band centre bore, 3-alloy steel bar, 4-alloy block, 5-external screw thread.
The specific embodiment
Below in conjunction with embodiment the present invention is further specified.But be not limited thereto.
Drilling rod straight line as shown in Figure 1 creeps into device; It is on a cylinder 2 that has a centre bore, longitudinally evenly to weld 4-8 to alloy steel bar 3 at interval; With drilling rod precession direction is direction of advance, and a plurality of alloy blocks 4 in longitudinal separation welding before the every alloy steel bar 3 require alloy block 4 to be close to and own corresponding alloy steel bar 3; Cylinder 2 two ends are respectively equipped with and suitable internal thread of drilling rod 1 and external screw thread 5, the diameter of the entire outer diameter outline of creeping into device drill bit during less than boring.
The course of work and principle are following:
After creeping into a drilling rod, will creep into device and be contained between the 1st joint and the 2nd joint drilling rod, after creeping into two drilling rods, will creep into device and be contained between the 2nd joint and the 3rd joint drilling rod, continue to creep into by normal procedure afterwards.Since creep on the device alloy block evenly distributed for vertically, the radial load that drilling rod is received in drilling process is cancelled out each other, and it is indeformable greatly to creep into device hardness, thus the straight line that has kept holing creeps into.
The present invention used the boring centralizer 6 months in the high-order drill sites of the 1703 eastern coal-faces in Dezhou City official Zhao colliery, Shandong Province, 48 of the rock pores of constructing altogether, and 200 meters of the length of on average constructing, 258 meters of the longest construction length, qualification rate reaches 91.7%.
