The specific embodiment
Core of the present utility model provides a kind of brill, and this kind tube is drilled in when keeping higher drilling efficiency and also can be easy to propose boring mud from boring, thereby need not frequently more bit change in work progress, thereby has significantly improved efficiency of construction.In addition, another core of the utility model is for providing a kind of rotary drilling rig that comprises that above-mentioned tube bores.
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, Fig. 3 and Fig. 4, Fig. 2 is the structural representation that tube bores among a kind of embodiment of the utility model; Fig. 3 is the upward view that tube bores shown in Fig. 2; Fig. 4 is the vertical view that tube bores shown in Fig. 2.
In one embodiment, as shown in Figure 2, tube provided by the utility model bores, and is used for rotary drilling rig, comprises cylindrical shell 1 and is located at the top board 2 at cylindrical shell 1 top, and the diapire of cylindrical shell 1 is connected with the bottom and bores tooth 3, and top board 2 is connected with connection side 4.
On the basis of above-mentioned prior art, top board 2 further is connected with the augers that is positioned at cylindrical shell 1 inside.When drilling construction is carried out on the slate stratum, at first the bottom brill tooth 3 of tube brill contacts with slate, with the slate fragmentation, tube inside spin drill bit contacts with slate and continues fragmentation then, boring mud rises along the helical shape structure of augers, and along with this boring mud that continues that creeps into is compressed between cylindrical shell 1 and the described helical shape structure gradually, boring mud is difficult for dropping out in the tube, thereby once creep into the tube that finishes and bore when promoting, boring mud proposes thereupon.
As from the foregoing, tube provided by the utility model is drilled in when keeping higher drilling efficiency and also can be easy to propose boring mud from boring, thereby need not frequently more bit change in work progress, thereby has significantly improved efficiency of construction.
It should be noted that to be that the foregoing description does not limit for the structure and the set-up mode in cylindrical shell 1 thereof of augers, thus the augers of arbitrary structures and arbitrarily set-up mode all within protection domain of the present utility model.
Certainly, structure and set-up mode that can a kind of augers of specific design, such as, please refer to Fig. 2, described augers comprises pipe 51, this pipe 51 is connected on the top board 2 and is coaxial with cylindrical shell 1; The circumference outside of pipe 51 is wound with helical blade 52, and this helical blade 52 increases gradually along with extending its external diameter to the direction of top board 2, and helical blade 51 is provided with first and bores tooth 53, specifically, as shown in Figure 2, first bore the outer end that tooth 53 is located at helical blade 51.
When drilling construction is carried out on the slate stratum, at first the bottom brill tooth 3 of tube brill contacts with slate, with the slate fragmentation, on the tube internal helical blades 52 first bores tooth 53 and contacts the continuation fragmentation with slate then, 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 creep into the tube that finishes and bore when promoting, boring mud proposes thereupon.
Further, as shown in Figure 3, in order to improve drilling efficiency, the lower surface of pipe 51 is connected with cover plate 54, and the second brill tooth 55 is set on this cover plate 54, when creeping into, the bottom of cylindrical shell 1 was bored tooth 3 and was contacted also fragmentation with slate before this, and then second on the cover plate 54 bore that tooth 55 contact with slate and further fragmentation, is the further more broken slate of the brill tooth 53 of first on the helical blade 52 at last, thereby significantly improved drilling efficiency.
Further, as shown in Figure 2, be connected with backing plate 61 on the diapire of top board 2, pipe 51 is connected with backing plate 61, and pipe 51 is connected on the top board 2 by this backing plate 61.As shown in Figure 2, top board 2 is provided with through hole, and the aperture of this through hole is bigger, this moment is if pipe 51 directly is connected with top board 2, need do the external diameter of pipe 51 very big, thereby pipe 51 can occupy in the cylindrical shell than large space, obviously can reduce the space of depositing boring mud like this, reduce the ability of the extraction boring mud of tube brill.Obviously, pipe 51 is connected with top board 2 by backing plate 61, has just solved the problems referred to above.
Further, as shown in Figure 2, in order to improve the bonding strength between pipe 51 and the backing plate 61, pipe 51 circumferentially evenly can be connected with a plurality of reinforcement gussets 62, and respectively strengthen gusset 62 and all be connected with backing plate 61.
Please refer to Fig. 2 and Fig. 5, Fig. 5 is the A-A cross section view that tube bores shown in Fig. 2.
In above-mentioned any embodiment, in order to improve the bonding strength between top board 2 and the cylindrical shell 1, can further be provided with long gusset 71 on the diapire of top board 2, and be somebody's turn to do of the sidewall connection of the two ends of long gusset 71 respectively at corresponding cylindrical shell 1.
Certainly, as shown in Figure 5, in order further to improve bonding strength, the number of long gusset 71 is two, and both be arranged in parallel.
As Fig. 2 and shown in Figure 5, can further be connected with horizontal bar 72 on the diapire of top board 2, and the two ends of this horizontal bar 72 are connected with corresponding long gusset 71 respectively.Obviously, formed a stable structure body by top board 2, long gusset 71 and horizontal bar 72, the bonding strength between this structure and the cylindrical shell 1 is significantly improved.
In the above-described embodiments, the utility model does not limit for the quantity that is provided with of helical blade 52, thereby no matter a slice, two or multi-disc are set, all within protection domain of the present utility model.When a slice helical blade 52 was set, augers was single spiral shell, and when two helical blades 52 were set, augers was two spiral shells, and the concrete structure of this pair spiral shell shape augers is as follows:
The number of helical blade 52 is two, is respectively first helical blade and second helical blade, and these two helical blade wound in parallel are on pipe 51; Between the blade layer of adjacent described first helical blade and the blade layer of described second helical blade, near the external diameter of the blade layer of top board 2 greater than external diameter away from the blade layer of top board 2.
With respect to single spiral shell structure, its first brill tooth 53 of the augers of two spiral shell structures is more even along circumferentially distributing, thereby the balance of creeping into is good, and feasible is bored the center that is difficult to depart from boring.
In addition, the utility model also provides a kind of rotary drilling rig, and this rotary drilling rig comprises drilling rod, and comprises that the tube among above-mentioned any embodiment bores, and described drilling rod is connected with the connection side 4 that tube bores.Other parts of described rotary drilling rig can be with reference to prior art, and this paper no longer launches.
More than rotary drilling rig provided by the utility model and tube thereof bored be 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.
