Abstract
The utility model discloses a coal-bed core-taking drilling rod which comprises a core-taking cylinder and a drilling bit fixed at the front end of the core-taking cylinder; the rear end of the core-taking cylinder is connected with a dismountable drilling tail by a thread; a connecting rod is fixed on the end surface of the drilling tail in axial direction; and a diamond sheet is fixed at the edge of the front end of the drilling bit. When the drilling rod is used for taking cores, the connecting rod is fixed on a frequently-used hand-held pneumatic drilling machine for coal mines; an anti-jumping drilling rod is arranged on the dismountable drilling tail; the anti-jumping drilling rod is used for drilling firstly; subsequently the anti-jumping drilling rod is taken when drilling to the depth of about 12m; and the core-taking cylinder is arranged on the drilling tail and drilling can continue for 2 to 3 minutes, thus completing the core taking operation. By adopting the drilling rod, the operation procedures are optimized, operators can be saved, the core-taking time can be shortened, and the generated core-taking cost is reduced.
Description
Technical field
The utility model relates to a kind of drilling rod, particularly a kind of coal seam coring drill rod.
Background technology
According to the requirement of DGC type gas bearing capacity determinator, carry out operation with supporting drilling rod and corer when in the coal seam, getting core, must creep into corresponding rig.At present, the special drilling machine equipment of purchase is got core test, can reach the requirement of getting core, but because the rig own vol is big, no running gear, operation sequence are loaded down with trivial details, needs water supply, electric power system perfect when drilling, and the preliminary preparation amount is big; And rig must repeatedly be moved rig when coplanar does not carry out coring in the same district, and move rig all needs the forklift traction to cooperate to finish at every turn; Minimum time spent of three work planes three of detecting a driving team is to Fourth Shift, and minimum 4 people operation is bored in every Hangzhoupro.Carrying is bored in Hangzhoupro between the zones of different, and minimum to need the time be 8 hours, so just causes that coring is consuming time, the work holdup, waste of manpower resource, has a strong impact on production operation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of coal seam coring drill rod, and this drilling rod is easy to dismounting, is used in combination with other drilling rod.
For overcoming the above problems, the technical solution adopted in the utility model is: a kind of coal seam coring drill rod, comprise coring tube and the drill bit that is fixed on the coring tube front end, the coring tube rear end is connected with a detachable tail that bores by screw thread, boring the breech face axial restraint has connecting rod, and the chisel edge edge is fixed with the Buddha's warrior attendant sheet.
When in the coal seam, getting core, connecting rod is fixed on the hand-held pneumatic rig commonly used of colliery, the protrusion-dispelling drilling rod is installed on detachable brill tail, use earlier the protrusion-dispelling rod boring, when creeping into about 12 meters positions, take off the protrusion-dispelling drilling rod, load onto coring tube described in the utility model and creep into again and can finish coring in 2～3 minutes boring tail.
The utlity model has following beneficial effect: (1) the utility model can with the rigs against outburst coordinating operation, with purchase rig and get core contrast, only need operating personnel 2～3, manpower is saved 1～2 people, same work plane coring saved time more than 7.5 hours, the cooperation that core does not need forklift is not got in same district between the coplanar, and can carry out in the working surface production gap, does not influence the production of driving face.(2) test by work plane in zones of different, rigs against outburst creeps into 15～16 minutes 12 meters position times spent, 2～3 minutes changing-over coring drill rod times spent, gets 2～3 minutes core times spent, getting a dant core time spent like this is about 19～33 minutes, has improved the core speed of getting greatly.(3) flow chart is optimized, the operating personnel saves, get the core time saves, and the core cost of getting that is produced simultaneously reduces.
Description of drawings
Fig. 1 is the structural representation of the utility model coal seam coring drill rod.
Fig. 2 is the connect schematic diagram of brill tail with coring tube.
Among the figure, the 1-coring tube; The 2-drill bit; 3-bores tail; The 4-connecting rod; 5-Buddha's warrior attendant sheet; The 6-locking key.
The specific embodiment
A kind of coal seam described in the utility model coring drill rod comprises coring tube 1 and the drill bit 2 that is fixed on coring tube 1 front end, and coring tube 1 rear end is connected with a detachable tail 3 that bores by screw thread, bores tail 3 end face axial and is fixed with connecting rod 4.The chisel edge edge is fixed with Buddha's warrior attendant sheet 5.
During making, with diameter is that 63 millimeters coring drill rod is as the body of rod, Buddha's warrior attendant sheet 5 being welded of coring tube 1 front end of drilling rod according to certain angle, and the circumferential surface at coring tube 1 adds that spiral blade is used to ickings, add detachable brill tail 3 of weldering in drilling rod coring tube 1 rear end according to protrusion-dispelling drill rod connector principle, bore tail 3 and adopt external screw thread, internal thread is adopted in coring tube 1 rear end, and boring tail 3 can be connected with the protrusion-dispelling drilling rod with the coring tube 1 of coring drill rod respectively.Connecting rod 4 is fixedlyed connected with rig by locking key 6,
When the coring of coal seam, the protrusion-dispelling rod boring that utilizes 76 millimeters of diameters earlier withdraws from the protrusion-dispelling drilling rod to assigned address, connects homemade coring drill rod, creeps into forward, fixes a point to get core, with this cycle operation.
Claims (1)
