Description
Technical field
The invention belongs to the technical field of the drilling rod of working seam, be specifically related to a kind of honeycombed drilling rod and linkage thereof.
Background technology
Outburst-prevention drill rod, hole in coal seam exactly, then extract gas out by boring, effectively to utilize gas, and prevent the drilling rod of Gas Disaster, existing drilling rod is nearly all air inlet or water inlet from drilling rod, from giving vent to anger between drilling rod and hole wall or taking coal dust out of while water outlet, such working method, is easy to occur collapse hole after soft seam, can not effectively creep into, so drilling depth is little.Chinese patent discloses the utility model patent that application number is 201120030403.2, although arrange multiple axially extending bore in this drilling rod, and is connected by pipe collar between drilling rod, when but this kind is connected to practical application, sealing effectiveness is bad, because connecting portion parts are simple, connects effect bad.
Summary of the invention
The technical problem to be solved in the present invention is that traditional drilling rod can not be given vent to anger or water outlet from bar inside, easily makes soft seam occur collapse hole, and boring is not dark, connects effect bad, poor sealing between drilling rod.
In order to solve the problems of the technologies described above, the invention provides one can give vent to anger or water outlet in bar simultaneously, avoids soft seam to occur collapse hole, thus makes boring comparatively dark, and good connecting effect between drilling rod, the honeycombed drilling rod that sealing performance is excellent and linkage thereof.
A kind of honeycombed drilling rod, comprise sleeve pipe and be arranged on the sub-pipe in sleeve pipe, sub-pipe and sleeve pipe are fixed by end socket by two ends, described end socket stretches out cannula tip, the diameter of one end extension is greater than the diameter of other end extension, and the extension of minor diameter end socket and large-diameter seal head all arranges external screw thread.
Further, limit described sub-pipe and comprise large son pipe and boy's pipe.
Further, limit described minor diameter end socket and large-diameter seal head be provided with the dowel hole matched.
A linkage for honeycombed drilling rod, described minor diameter end socket overcoat cuff, cuff is positioned on minor diameter end socket by pressure ring, and large-diameter seal head is connected with cuff spiral.
Further, limit described pressure ring to be connected with minor diameter end socket spiral.
Further, limit between described cuff and sleeve pipe and be provided with joint ring.
Further, limit described joint ring and be made up of rubber layer and metal level compound, the one deck contacted with sleeve pipe is rubber layer, and another layer is metal level.
Technique scheme can reach following beneficial effect:
1, this kind of drilling rod, arrange son pipe in sleeve pipe, can ventilate in drilling rod inside simultaneously, water flowing, avoids soft seam to occur collapse hole, thus make boring darker.
2, connected by linkage between drilling rod, sealing performance is excellent, good connecting effect.

Detailed description of the invention
The invention provides a kind of honeycombed drilling rod and linkage thereof, as shown in drawings, this honeycombed drilling rod comprises sleeve pipe 1 and is arranged on the sub-pipe in sleeve pipe 1, sub-pipe and sleeve pipe 1 are fixed by end socket by two ends, described end socket stretches out cannula tip, the diameter of one end extension is greater than the diameter of other end extension, and the extension of minor diameter end socket (2) and large-diameter seal head (3) all arranges external screw thread 4.
As the embodiment optimized, above-mentioned sub-pipe comprises large sub-pipe 9 and boy's pipe 10.Sub-pipe is like this according to different demands, and different sub-pipes can simultaneously water flowing or ventilation, makes drilling rod performance better.
As optimize embodiment, above-mentioned minor diameter end socket 2 with large-diameter seal head 3 is provided with the dowel hole 7 matched.Between two drilling rods when connection, dowel hole 7 can be utilized first by two drilling rod location, then rotate cuff spiral and connect, thus it is more convenient that two drilling rods are connected.
Honeycombed drilling rod couples together by the linkage of this honeycombed drilling rod, and its medium-small diameter end socket 2 overcoat cuff 5, cuff 5 is positioned on minor diameter end socket 2 by pressure ring 6, and large-diameter seal head 3 is connected with cuff 5 spiral
As the embodiment optimized, above-mentioned pressure ring 6 is connected with minor diameter end socket 2 spiral.The location of pressure ring 6 pairs of cuffs 5 can be made so more stable, install also more convenient.
As the embodiment optimized, the diameter of above-mentioned cuff 5 and the equal diameters of sleeve pipe 1, and be provided with joint ring 8 between cuff 5 and sleeve pipe 1.Joint ring 8 can make sealing performance between cuff 5 and sleeve pipe 1 better, prevents gap between the two from entering the foreign material such as cinder.
As the embodiment optimized, above-mentioned joint ring 8 is made up of rubber layer 81 and metal level 82 compound, and the one deck contacted with sleeve pipe 1 is rubber layer 81, and another layer is metal level 82.Due to two drilling rods connect in, cuff 5 relative to sleeve pipe 1 rotation, metal level 82 contacts with cuff 5, can make cuff 5 smooth rotation, rubber layer 81 contact with sleeve pipe 1 connect screw in can play certain cushioning effect.
Two honeycombed drilling rods are when being interconnected, first with two end sockets, sub-pipe is installed, then sleeve pipe 1 is sleeved on end socket, such honeycombed drilling rod just combines, when two drilling rods connect, first by two end socket location, sub-pipe sealed mutually docking or connect together, then constantly cuff 5 is rotated, cuff 5 one end spiral is arranged in large-diameter seal head 3, and the other end is fixed on minor diameter end socket 2 by pressure ring 6, and pressure ring 6 is arranged on minor diameter end socket 2 by screw thread, play the positioning action to cuff 5, two drilling rods are interconnected closely.Middle joint ring 8 is also corresponding plays sealing and cushioning effect.
