The specific embodiment
Core of the present utility model is dug drilling tool for a kind of revolving is provided, and this revolves the structure design of digging drilling tool when being the geological form of sloped contact surface in the face of soft formation and hard formation, has positioning and guiding performance preferably, can avoid occurring the inclined hole phenomenon.In addition, another core of the utility model comprises that for providing a kind of this revolves the rotary drilling rig that digs drilling tool.
In order to make those skilled in the art understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 2 and Fig. 3, Fig. 2 revolves the structural representation that digs drilling tool among a kind of embodiment of the utility model; Fig. 3 revolves the vertical section structure schematic diagram that digs drilling tool among Fig. 2.
In one embodiment, provided by the utility model revolving dug drilling tool, comprises cylindrical shell 1, and the top of this cylindrical shell 1 is connected with top board 2, is connected with connection side 4 on the roof of top board 2; The bottom of this cylindrical shell 1 is provided with the bottom and bores tooth 3.On this basis, as shown in Figures 2 and 3, provided by the utility model revolving dug drilling tool and also comprised augers, and described augers is located in the cylindrical shell 1, and the bottom of described augers is stretched out by the bottom of cylindrical shell 1.
In the work progress, be under the operating mode of sloped contact surface between soft formation and the hard formation, when drilling tool creeps into hard formation, because stretch out from the bottom of cylindrical shell 1 bottom of augers, thereby first the contact with sloped contact surface of augers crept into, because augers and contacting of sloped contact surface are crept into and are similar to a kind of point and contact and creep into, thereby the positioning and guiding better performances of augers, can run-off the straight; Along with augers continues to creep into, the bottom of cylindrical shell 1 one sides is bored tooth 3 and contact with the rock stratum, inclined-plane and creep into, and at this moment owing to the positioning and guiding of augers, cylindrical shell 1 can run-off the straight; Along with continuing to creep into, the bottom brill tooth 3 of cylindrical shell 1 opposite side contacts with the rock stratum, inclined-plane and creeps into, this moment, cylindrical shell 1 integrated radial pierced in the hard formation, cylindrical shell 1 also plays the positioning and guiding effect, when cylindrical shell major part vertically pierces in the hard formation, finish the sloped contact surface location of soft formation and hard formation, can use other drilling tools instead and creep into, and perhaps adopts the present invention to continue to creep into.
In addition, provided by the utility modelly revolve that to dig drilling tool only be to revolve cylindrical shell 1 inside of digging drilling tool in the prior art to have added augers, other structures are not made change, thus simple in structure, easy for installation, and processing cost is low.
In technique scheme, can make further design to the mechanism of augers.Such as, as shown in Figures 2 and 3, described augers comprises mandrel 51, this mandrel 51 is located in the cylindrical shell 1 and is connected on the top board 2; On this basis, the circumferential outside of mandrel 51 is wound with helical blade 52, and helical blade 52 is provided with first and bores tooth 53; Particularly, the marginal position of helical blade 52 is provided with first and bores tooth 53, and first quantity of boring tooth 53 can be for a plurality of.
In the work progress, the augers of said structure has on the basis of positioning and guiding performance preferably, and its association's slag ability is more intense; Particularly, along with creeping into, boring mud rises along helical blade 52, and along with this boring mud that continues that creeps into is compressed between cylindrical shell 1 and the helical blade 52 gradually, boring mud is difficult for dropping out in the cylindrical shell 1, thereby once creeps into when finishing drilling tool lifting, and boring mud proposes thereupon.
Particularly, helical blade 52 is along with the direction to top board 2 is extended, and its external diameter can increase gradually, thereby association's slag ability is stronger, and destroys the wider of rock stratum, makes the inwall of cylindrical shell 1 and the rock between the mandrel 51 suffer fragmentation as far as possible.
In addition, as shown in Figure 3, the lower surface of mandrel 51 can be connected with cover plate 54, can be provided with second on the cover plate 54 and bore tooth 55.In the work progress, when creeping into the inclined-plane hard formation, on the cover plate 54 second bores tooth 55 and creeps into and locate prior to the contact of inclined-plane hard formation, then along with creeping into, on the helical blade 52 first brill tooth 53 contacts with the inclined-plane hard formation and creeps into, and this kind structure design has further improved the positioning and guiding performance of augers.
Please refer to Fig. 4, Fig. 5 and Fig. 6, Fig. 4 for revolve among Fig. 2 dig drilling tool A-A to sectional view; Fig. 5 revolves the upward view that digs drilling tool among Fig. 2; Fig. 6 revolves the vertical view that digs drilling tool among Fig. 2.
In above-mentioned any technical scheme, can also make further improvement.Such as, as shown in Figure 3 and Figure 4, further being connected with stiffener 6 between the inwall of cylindrical shell 1 and the mandrel 51, the quantity of this stiffener 6 can be for a plurality of, and circumferentially evenly being provided with along mandrel 51.6 pairs of mandrels 51 of this stiffener play fixation, prevent that it from rocking in drilling process, thereby can improve mandrel 51 reliability of positioning in the axial direction.
Further, as shown in Figure 3 and Figure 4, further be provided with the 3rd on the lower surface of stiffener 6 and bore tooth 61.The 3rd bores tooth 61 can further carry out fragmentation to the rock stratum between cylindrical shell 1 inwall and the mandrel 51, makes crushing rock formation abundant.
Particularly, as shown in Figure 5, in the footpath of cylindrical shell 1 upwards, the 3rd bore tooth 61 be located at the bottom bore tooth 3 with apart between the mandrel 51 first brill tooth 53 farthest.In the work progress, apart from mandrel 51 first boring tooth 53 and bore tooth 3 with the bottom and upwards also have a segment distance in cylindrical shell 1 footpath farthest, the rock in this distance range is owing to can not get boring the tooth fragmentation, thereby it is broken and insufficient; And in said structure since the 3rd bore tooth 61 be located at the bottom bore tooth 3 with apart from mandrel 51 first boring between the tooth 53 farthest, thereby can carry out abundant fragmentation by 61 pairs of these part rocks of the 3rd brill tooth.
As shown in Figure 3, mandrel 51 can further be connected on the top board 2 by backing plate 71; Simultaneously, in order to improve the reliability between mandrel 51 and the backing plate 71, as shown in Figure 3 and Figure 4, further be provided with a plurality of reinforcement gussets 72 between the circumferential side wall of mandrel 51 and the backing plate 71.
In addition, the present invention also provides a kind of rotary drilling rig, comprises drilling rod; Described rotary drilling rig comprises that also above-mentioned each described revolving digs drilling tool, and as shown in Figure 2, the roof of top board 2 is connected with connection side 4, and described drilling rod is connected with connection side 4; Other parts of described rotary drilling rig can be with reference to prior art, and this paper no longer launches.
More than the utility model provided to revolve dig drilling tool and rotary drilling rig is described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
