Advantage of the present utility model and effect: 1, mechanization once-forming boring, need not reaming, can get out the designated lane of major diameter, gentle dip, long distance, the pore cross section rule that is got out, bearing capacity is strong, good stability, need not to carry out supporting, during boring country rock is not produced vibration limits, work efficiency height, safety are good; 2, boring procedure promptly is a mining process, when being applied to special places such as Pillar Recovery, old liberated area second mining, railways and water-bodies, except have the work efficiency height, rate of extraction high energy fully reclaims the coal resources, the most important thing is to have solved personal safety problem under the bigger operating environment of danger, workman's operation in the tunnel of supporting is arranged, needn't enter stope (circle hole), and residual circular hollow coal column has very strong bearing capacity, safe and reliable.
The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.
Fig. 1 is the utility model structure chart;
Among the figure, two back brace oil cylinders 5 are fixed on the upper back of base 13, and form a complete and firm supporting system with base.The piston rod of back brace oil cylinder stretches out support one side coal group 4, base is pressed in the opposite side coal group 15 firmly, make base become a similar fixing base (as the back brace oil cylinder is not set, then base must fixedly secure with roadway floor 11 (Horizon), 3 is back), guide rail 6 on it has also just become fixed guide (select the square-section guide rail for use, and rhombus being placed good stability).Unit head 9 rides on the square rail of base (effect of guide strip is that avoid directly sliding between unit head and the guide rail sassafras that rubs is worn and torn, and the guide strip wearing and tearing can be changed) by guide strip 7, by advancing oil cylinder 8 to push ahead.Advance oil cylinder to be installed in the middle of the rear portion of base.Advance piston rod one end of oil cylinder to be hinged on the guide strip, its middle part is fixed on the base.Unit head links by an end of tapered thread and spiral hollow drill pipe 1, and the other end of auger stem then links by the quill shaft 18 of tapered thread and another root drilling rod or combined type drill bit.Between combined type drill bit and unit head, can dock many auger stems.Auger stem is provided with helical blade 2, the coal that drilling forms can be delivered to outside the hole during boring.The combined type drill bit is a cylinder type, is furnished with pick 16 at the front end of cylinder 21, all is furnished with helical blade 20,22 on the inside and outside wall of cylinder.Outside helical blade 22 can support and locate drill bit.Inner helical blade 20 can be delivered to auger stem along the hole with the coal that drilling forms, and sends transporter 23 below being located at the base front end by auger stem again, Coal Transport can be gone out.Between auger stem and base, be provided with two big carrying rollers 10,12, be parallel, pitch arrangement is arranged, and parallel with the center of creeping into.Combined type drill bit and auger stem are bearing on the big carrying roller, can relatively rotate between auger stem and the big carrying roller.Big carrying roller two supports and can rotate on base on the carriage 14 of base.
Unit head adopts two low speed high torque hydraulic motors, driven in synchronism gear wheel, main shaft, transfer torque; The two-stage double acting of planker configuration of unit head bottom advances oil cylinder, applies long stroke and enough slide forces with short cylinder body to unit head; Support adopts cuboid, short molding box formula structure, and its both sides, top configuration square rail is in order to control the accurate front and back translation of unit head and to bear positive and negative moment; The box back plate is external except that laying propulsion cylinder, and also symmetry is installed two back brace oil cylinders, with the stretching rib, and the propelling counter-force of contending with; Establish two parallel big carrying rollers in the casing, the rotation of carrying drilling tool advances and accurately centering; The bottom half space can be laterally or the portrait configuration transporter, and the coal of extraction is transported.The combined type augers is made up of helix drum 21, disc 19, quill shaft 18, center bit 17, pick 16 etc., and front end becomes multistage taper cut face by center bit with several ten pick arrangement, creep into the usefulness height, feel relieved; All arrange twin-feed spiral blade 20,22 inside and outside the cylinder, both obtained stable support, can efficiently carry coal again.Auger stem is made up of quill shaft 1 and twin-feed spiral blade 2, and interior outer cone thread is processed in the termination, front and back, in order to and drill bit or many drilling rods between be coupled to each other.Owing to be subjected to the restriction of span length, every drilling rod is all shorter, needing frequent butt joint or shackle during operation, be again that nearly level, long distance are crept into, thereby it is different with the normally used drilling rod of all kinds of rigs, except the effect of transfer torque, slide force and hollow channel water delivery and, also to carry coal, and will rely on the sliding-contact of helical blade outer rim and hole wall, obtain stable support, avoid drilling rod sedimentation and beat, guarantee that straight line creeps into.
This rig is some independent monomer parts, and it is in place to transport to the scene, and aggregate erection connects hydraulic pressure, power supply, water system, just can implement the operation function of this rig.It is when operation, and at first the unit head by main frame drives the rotation of combined type augers, and the end thrust by advancing oil cylinder to transmit, and makes drill bit cutting ore body enter the coal seam.Unit head is turned on connecting of drill bit and is returned original position then, and the drilling rod of packing into starts unit head rotation and propelling again, the axle head screw thread of connection and drilling rod, drill bit, and the cutting that can carry out next stroke advances.The drilling rod that continues so one by one, reach the length requirement of boring after, withdraw from drilling rod and drill bit again, promptly finished bore operation.The process of boring promptly cuts coal, and the helical blade of drill bit and drilling rod transports out it from the hole, transport through transporter again.
