Abstract
The utility model aims to solve the technical problems of high probability of hole collapse of a soft coal seam, shallow drilling, poor connecting effect between drill stems and poor sealing property existing in that the conventional drill stem since air or water cannot be discharged from the rod, and provides a honeycomb-shaped drill stem and a connecting device thereof. The honeycomb-shaped drill stem comprises a bushing and sub-pipes, wherein the sub-pipes are arranged in the bushing; the sub-pipes and the bushing are fixed at the two ends by seal heads; the seal heads extend out of the end parts of the bushing; the diameter of the extended part at one end is greater than the diameter of the extended part at the other end; the extended parts at the two ends are both provided with external threads; a hoop is sleeved outside the seal head with a small diameter and is positioned on the small-diameter seal head by a pressing ring; the large-diameter seal head is in screwed connection with the hoop. According to the drill stem, air and water can be simultaneously discharged from the rod so as to prevent hole collapse of the soft coal seam and realize deeper drilling, a good connecting effect between the drill stems and superior sealing property.
Description
Technical field
The utility model belongs to the technical field of the drilling rod of working seam, is specifically related to a kind of cellular drilling rod and linkage thereof.
Background technology
The protrusion-dispelling drilling rod, in the coal seam, hole exactly, extract gas out by boring then, effectively utilizing gas, and prevent the drilling rod of gas disaster, existing drilling rod nearly all is 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 water outlet the time, such working method is easy to occur the hole of collapsing behind soft seam, can not effectively creep into, so drilling depth is little.It is 201120030403.2 utility model patent that Chinese patent discloses application number, though a plurality of axially extending bores are set in this drilling rod, and connect by pipe collar between the drilling rod, when but this kind is connected practical application, sealing effectiveness is bad, because the connecting portion parts are simple, it is bad to connect effect.
The utility model content
The technical problems to be solved in the utility model is that traditional drilling rod can not be given vent to anger or water outlet from bar inside, makes soft seam the hole of collapsing occur easily, and it is not dark to hole, and it is bad to connect effect between the drilling rod, poor sealing.
In order to solve the problems of the technologies described above, the utility model provides a kind of and can give vent to anger simultaneously or water outlet in bar, avoids soft seam the hole of collapsing to occur, thereby makes boring darker, and good connecting effect between the drilling rod, cellular drilling rod and linkage thereof that sealing performance is good.
A kind of cellular drilling rod, comprise sleeve pipe and be arranged on the interior child pipe of sleeve pipe, two ends are fixed child pipe and sleeve pipe by end socket, 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 major diameter end socket all arranges external screw thread.
Further, limit described sub-pipe and comprise big son pipe and boy's pipe.
Further, limit described minor diameter end socket and be provided with the dowel hole that matches with the major diameter end socket.
A kind of linkage of cellular drilling rod, described minor diameter end socket overcoat cuff, cuff is positioned on the minor diameter end socket by pressure ring, and the major diameter end socket is connected with the cuff spiral.
Further, limiting described pressure ring is connected with minor diameter end socket spiral.
Further, limit between described cuff and the sleeve pipe and be provided with joint ring.
Further, limit described joint ring by rubber layer and metal level is compound forms, with the contacted one deck of sleeve pipe be rubber layer, another layer is metal level.
Technique scheme can reach following beneficial effect:
1, this kind drilling rod arranges the son pipe in the sleeve pipe, can ventilate simultaneously in drilling rod inside, water flowing, avoids soft seam the hole of collapsing to occur, thereby make boring darker.
2, connect by linkage between the drilling rod, sealing performance is good, good connecting effect.
Description of drawings
Fig. 1 is the linkage partial structurtes schematic diagram of cellular drilling rod;
Fig. 2 is the sectional structure chart along A-A line among Fig. 1;
Fig. 3 is the right view of Fig. 1.
The specific embodiment
The utility model provides a kind of cellular drilling rod and linkage thereof, as shown in drawings, this cellular drilling rod comprises sleeve pipe 1 and is arranged on child pipe in the sleeve pipe 1, two ends are fixing with child pipe and sleeve pipe 1 by end socket, 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 major diameter end socket 3 all arranges external screw thread 4.
As the embodiment of optimizing, above-mentioned sub-pipe comprises that big son pipe 9 and boy manage 10.Sub-pipe like this is according to different demands, and the water flowing simultaneously of different sub-pipes or ventilation make the drilling rod performance better.
As the embodiment of optimizing, above-mentioned minor diameter end socket 2 is provided with the dowel hole 7 that matches with major diameter end socket 3.Connection the time, can utilize dowel hole 7 earlier with two drilling rods location between two drilling rods, rotate the cuff spiral then and connect, thereby it is more convenient that two drilling rods are connected.
The linkage of this cellular drilling rod links together cellular drilling rod, its medium-small diameter end socket 2 overcoat cuffs 5, and cuff 5 is positioned on the minor diameter end socket 2 by pressure ring 6, and major diameter end socket 3 is connected with cuff 5 spirals.
As the embodiment of optimizing, above-mentioned pressure ring 6 is connected with minor diameter end socket 2 spirals.Can make the location of 6 pairs of cuffs 5 of pressure ring more stable like this, install also more convenient.
As the embodiment of optimizing, the equal diameters of the diameter of above-mentioned cuff 5 and sleeve pipe 1, and be provided with joint ring 8 between cuff 5 and the sleeve pipe 1.Joint ring 8 can make between cuff 5 and the sleeve pipe 1 sealing performance better, prevents that slit between the two from entering foreign material such as cinder.
As the embodiment of optimizing, above-mentioned joint ring 8 is by rubber layer 81 and 82 compound compositions of metal level, with sleeve pipe 1 contacted one deck be rubber layer 81, another layer is metal level 82.Because when two drilling rods connected, in rotation, metal level 82 contacted with cuff 5 cuff 5, and cuff 5 is rotated smoothly with respect to sleeve pipe 1, rubber layer 81 and sleeve pipe 1 contact being connected can play certain cushioning effect when screwing.
Two cellular drilling rods are when interconnecting, with two end sockets pipe is installed earlier, then sleeve pipe 1 is sleeved on the end socket, cellular like this drilling rod just combines, when two drilling rods connect, earlier two end sockets are located, with the child pipe seal mutually the butt joint or connect together, constantly rotate cuff 5 then, cuff 5 one end spirals are installed on the major diameter end socket 3, and the other end is fixed on the minor diameter end socket 2 by pressure ring 6, and pressure ring 6 is installed on the 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 also corresponding playing seals and the buffering effect.
