Abstract
The invention discloses a tool used during coal mine and coal road constructions, particularly relates to a wind-water dual-purpose inserted outburst-prevention drill rod used during drilling. The technical scheme used for solving the technical problems in the invention is as follows: a drill tail inserted rod (2) is axially connected at the right side of a connection shaft (1) of a wind-water feeding mechanism; the right end of a connection drill rod (10) is connected with the left side of the connection shaft (1) of the wind-water feeding mechanism, and the right end of the connection drill rod (10) is connected with a drill rod connection sleeve (15); and a third pore-expanding tooth (17) is welded at the front end of the drill rod connection sleeve (15) and at the periphery of the joint of a drill rod (28) with minor diameter, and a second pore-expanding tooth (26) and a first pore-expanding tooth (25) are progressively welded on the drill rod (28) with minor diameter; and a spiral drill is arranged at the left top end of the drill rod (28) with minor diameter. The drill rod of the invention has the beneficial effects that because a three-layer ladder-shaped progressive drilling mode is designed and the advanced wind-water feeding mechanism and a multi-layer sealing convex key concave groove connecting mode are adopted, the drilling depth is increased, wind and water can be fed during drilling, and no drill clamping, no hole jetting, no shock bumps in the mine as well as wind and water dust fall are achieved, thereby quickening the speed of drilling and guaranteeing the safety of construction.
Description
Technical field: the instrument that uses when the present invention relates to the coal road construction of a kind of colliery, the geomantic omen dual-purpose plug-in type protrusion-dispelling drilling rod that uses when specifically being boring.
Background technology: at present, in the construction of colliery, for the prominent mine of height, coal needs to beat protrusion-dispelling boring to construction.The pressure-bearing gas bearing capacity is bigger in coal body; beat when discharging boring; owing to can not use wind or water, after 2-3 rice is got in boring, the coal big gun occur ringing through regular meeting; stick of tool, breaking of rod bar phenomenon; so that cause the drilling rod maintenance capacity big, the drilling rod infringement is many, inefficiency; construction speed is slow, the more important thing is to have had a strong impact on construction safety.An also useful little drill bit and the drilling rod that the reaming tooth is formed, because the diameter gap is bigger, radially resistance is big, construction speed is slower, and owing to can not blow simultaneously and water, result of use is unsatisfactory.
Summary of the invention: the present invention has changed the drawback of former drilling rod, and a kind of four layers of trapezoidal laddering drilling rod and air-supply water-bound and two-stage geomantic omen open-work are provided, and penetration rate is accelerated, and saves physical and continuous drill point and bores, not the dual-purpose plug-in type protrusion-dispelling in the geomantic omen of spray orifice drilling rod.
The technical scheme that technical solution problem of the present invention is adopted is: bore tail inserted link 2 axially is connected air-supply water mechanism by connecting pin 4 connecting axle 1 right side, jointed rod 10 right-hand members axially are connected with connecting axle 1 left side of air-supply water mechanism by first steady pin 11, and left end axially is connected with drilling rod adapter sleeve 15 by second steady pin 12; The 3rd reaming tooth 17 is welded on drilling rod adapter sleeve 15 front ends and minor diameter drilling rod 28 junction peripheries, and laddering at the minor diameter drilling rod 28 welding second reaming tooth 26 and the first reaming teeth 25, and augers 24 is arranged on minor diameter drilling rod 28 left tops.
The invention has the beneficial effects as follows: because the present invention has designed four layers of trapezoidal bore mode that goes forward one by one, adopted advanced air-supply water mechanism to be connected with two-stage geomantic omen open-work and multi-layer sealed protruding key groove, avoided the drawback that is threaded and tries to shirk responsibility, drilling depth is increased, can be under water-tight situation of not leaking out, when drilling construction, send the water air-supply, can play rotating, stop to resolve the drilling rod phenomenon, realized not stick of tool, spray orifice not, in/un-sound coal gun, geomantic omen depositing dust, thereby penetration rate is accelerated, save muscle power, ensured the safety of construction, drilling depth can reach 30-50 rice.And with low cost, dismantle easy to maintenance.
