The specific embodiment
It should be noted that, in the situation that do not conflict, embodiment and the feature in embodiment in the utility model can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Below in conjunction with Fig. 1 to Fig. 2, the utility model is revolved to the preferred embodiment that digs drilling tool and be described in further detail.
The present embodiment provides a kind of revolving to dig drilling tool, comprises connection side 1, top board 3 and cylindrical shell 4; Wherein, top board 3 is fixedly connected on connection side 1 below; Cylindrical shell 4 is fixedly connected with top board 3, and the bottom of cylindrical shell 4 is provided with a plurality of subdrilling teeth 12; Revolve and dig drilling tool and also comprise that a plurality of cylindrical shells bore teeth 6; A plurality of cylindrical shells bore tooth 6 and distribute in the shape of a spiral at drum surface.Cylindrical shell bores tooth 6 and cylinder subdrilling tooth 12 is to be pick, certainly, also can be the brill tooth of other types.The utility model is not done restriction at this.The number of pick is definite according to actual condition, and the utility model is not done restriction to this.
When using the present embodiment, generally the height of cylindrical shell is suitably increased, and then when creeping into rock stratum, inclined-plane, the correcting effect can be better played in increasing of cylindrical shell.Simultaneously, cylindrical shell, in drilling process, in case tilt along the inclined-plane rock, can produce extruding force with the scar of inclined-plane rock, and in the rotating process of drilling tool, lower side pick cutting abrasion inclined-plane rock, until boring is vertical.
As can be seen here, the present embodiment revolves and digs drilling tool by at cylindrical shell, spiral helicine brill tooth being installed, and has solved rotary drilling rig occurs when carrying out the drilling construction of Hen Dade inclined-plane, inclination angle rock the problem of creeping into the hole inclination.
In addition, spiral is that cylindrical shell bores a kind of preferred situation that tooth distributes, and the present invention does not do restriction to distribution form.
Preferably, cylindrical shell bores the bottom that tooth 6 is arranged at cylindrical shell 4 surfaces, and for the problem that solves " hole deviation ", cylindrical shell brill tooth 6 is arranged at bottom and just can addresses the above problem.
As can be seen from Figure 1, revolve and dig drilling tool and also comprise gusset 2; Gusset 2 is fixedly connected between connection side 1 and top board 3.Specifically, connection side 1 can be welded on the top of top board 3, and passes through the connection effect that gusset 2 is strengthened between it, and the moment of torsion that drilling rod is transmitted is directly delivered to cylindrical shell 4, and then has reduced the shearing force of connection side to top board.Gusset 2 can be selected 4, can certainly be more, and the utility model is not done restriction to this.
For better guiding, the surface of cylindrical shell 4 also is provided with sliver 5.
The wall that digs drilling tool cylindrical shell 4 is very thin owing to revolving, and needs fixing position of boring tooth preferably also to be provided with the reinforcement structure, as the position of solid bottom cylinder subdrilling tooth 12 and cylindrical shell brill tooth 6.For this reason, revolve and dig drilling tool and can also be provided with the first stiffening ring 7 and the second stiffening ring 8; The first stiffening ring 7 is arranged at the inner surface of the bottom of cylindrical shell 4, because be the position of connecting cylinder subdrilling tooth 12 here.For example, the first stiffening ring 7 is welded on the inwall of cylindrical shell 4 concordant with its bottom, the cylinder subdrilling tooth 12 uniform cylinder body bottoms that are welded on, and toothholder 9 is connected with cylindrical shell 4, and, the angle layout straggly of a subdrilling tooth 12 and barrel wall.
The second stiffening ring 8 is arranged at the inner surface of the bottom of cylindrical shell 4, and this position range is to connect the position that cylindrical shell bores tooth.During enforcement, cylindrical shell bores tooth 6 and is embedded in cylindrical shell 4 bottoms by pick box, simultaneously, by second, strengthens reinforcing.
In addition, in order to strengthen revolving the intensity of digging drilling tool, to revolve, dig drilling tool and also comprise a plurality of arcs 10; Arc 10 is fixedly connected on the below of top board 3, and arc 10 is fixedly connected with cylindrical shell 4.Further, revolve and dig drilling tool and also comprise horizontal bar 11; Between a plurality of arcs 10, by horizontal bar 11, be connected.For example, top board 3 belows connect arc 10 by the mode of welding, and by horizontal bar 11, connect between arc 10, and arc 10 and cylindrical shell 4 welding, make its one-tenth as a whole.
Therein in embodiment, the cylindrical shell of cylindrical shell 4 bottoms bores tooth 6 apart from the bottom of cylindrical shell 4 450 millimeters, and angle is consistent with subdrilling tooth 12 an external tooth angle, along cylindrical shell, distributes in the shape of a spiral.When drilling tool crept into, drilling rod applied downward pressure to drilling tool and drives the drilling tool rotation, made to bore the beneath square rock of end pick cutting drilling, reached the purpose that pierces.When drilling tool pierced inclined-plane rock landforms, because the more conventional cylindrical shell of cylindrical shell 4 is high, higher cylindrical shell played guide effect better; And in a single day cylindrical shell 4 tilts along the inclined-plane rock at drilling process, with the scar of inclined-plane rock, can produce extruding force, and in the rotating process of drilling tool, cylindrical shell bores tooth 6 can cut half rock fast, until boring is vertical.As can be seen here, the present embodiment in this way, guarantees vertical degree of the peg hole, and then avoids the generation of hole deviation.
In addition, the type of the length of barrel diameter, cylindrical shell, brill tooth all can be adjusted according to the operating mode of reality, and the utility model is not done restriction to this.
To sum up, this practical revolving is dug drilling tool and is had following advantage:
The first, by the adjusting of conventional cylinder brill drilling tool height and on cylindrical shell the cloth tooth, the rotary drilling rig that has solved Hen Dade inclined-plane, inclination angle rock creeps into problem how to avoid hole deviation;
The second, installation is convenient, simple in structure, reliable, and economy is strong.
On the other hand, the utility model also provides a kind of rotary drilling rig, and this rotary drilling rig is provided with above-mentioned revolving and digs drilling tool.By having been described in detail, relevant part gets final product with reference to above-mentioned explanation due to the structure of rotary drilling rig.The utility model does not repeat them here.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
