Abstract
The utility model discloses a tool used during coal mine coal lane construction, in particular to a wind and water dual purpose inserted outburst prevention drill rod used when drilling a hole. A drill tail inserted rod (2) is axially connected at the right side of a connecting shaft (1) of a wind and water feeding mechanism by a connecting pin (4), the right end of a drill rod (10) is axially connected with the left side of the connecting shaft (1) of the wind and water feeding mechanism by a first fixation pin, the left end is axially connected with a drill bit connecting sleeve (15) by a second fixation pin, and the drill bit connecting sleeve (15) is welded with a drill bit (17). Because the wind and water feeding mechanism is designed, as well as a hollow drill rod, a three-layer trapezoid drill bit and a multi-layer sealing convex key and concave groove connecting method are adopted, the utility model avoids the disadvantage of easy abscission and slipping of threaded connection to cause a drilling depth to increase, can feed water and wind during drilling construction under the condition without water leakage and wind leakage, can correct inversion to put an end to the drill rod breaking phenomenon and realize no stick of tool, non hole jetting, no shock bumps in the mine as well as wind and water dust suppression, thereby causing the drilling speed to accelerate, saving physical strength, guaranteeing the construction safety, and causing the drilling depth to reach the range from 30 m to 50 m. The utility model has the advantages of low cost as well as convenient disassembly and maintenance.
Description
Technical field:
The instrument that the utility model uses when relating 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.
Summary of the invention:
The utility model has changed the drawback of former drilling rod, provides a kind of penetration rate that makes to accelerate, and saves the geomantic omen dual-purpose plug-in type protrusion-dispelling drilling rod of muscle power.It bores tail inserted link 2 axially is connected air-supply water mechanism by connecting pin 4 connecting axle 1 right side, drilling rod 10 right-hand members axially are connected with connecting axle 1 left side of air-supply water mechanism by first steady pin 11, left end axially is connected with drill bit adapter sleeve 15 by second steady pin 12, and drill bit adapter sleeve 15 and drill bit 17 weld together.Because the utility model has designed air-supply water mechanism, hollow drill and three layers of ripper step bit and multi-layer sealed protruding key groove connected mode have been adopted, 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.
