The specific embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 revolves for the utility model embodiment provides the partial structurtes schematic diagram that digs drilling tool; The partial structurtes schematic diagram that revolves another visual angle of digging drilling tool that Fig. 2 provides for the utility model embodiment.
Shown in Fig. 1 and Fig. 2, the utility model embodiment provides to revolve and digs the pick that drilling tool comprises drilling pipe 10 and is arranged on drilling pipe 10 bottoms, pick comprises the external tooth 20 of outward-dipping setting, with the internal tooth 40 that slopes inwardly and arrange, on the outer wall of drilling pipe 10 bottoms, be provided with outer protection tooth 30, the crown of outer protection tooth 30 is greater than the toothholder of external tooth 20 to the vertical distance of drilling pipe 10 outer walls to the vertical distance of drilling pipe 10 outer walls; So; dig in drilling tool drilling process revolving, the crown that can guarantee outer protection tooth 30 than the toothholder of external tooth 20 first with drilling pipe 10 outside rock stratum contact friction, make outer protection tooth 30 can protect the toothholder of external tooth 20 not to be worn; reduce the probability of changing toothholder; both improved operating efficiency, reduced again component cost, and can guarantee to change that tooth is working properly carries out; can not occur because toothholder is worn; cause changing tooth work and more bother, even change the situation of toothholder, further increase work efficiency.
Those skilled in the art are to be understood that, above-mentioned " outward-dipping ", " sloping inwardly " are to revolve that to dig the drilling pipe 10 of drilling tool be reference, the outside that is drilling pipe 10 is " outward ", the inside of drilling pipe 10 is " interior ", other relate to the term of " outward " and " interior " herein, all as reference standard.
Further, preferably the crown of outer protection tooth 30 is less than the crown of external tooth 20 to the vertical distance of drilling pipe 10 outer walls to the vertical distance of drilling pipe 10 outer walls.Like this can be revolving when digging drilling tool and creeping into; preferentially utilize external tooth 20 and rock stratum friction; outer protection tooth 30 is just participated in the work of creeping into where necessary; can externally protect to a certain extent tooth 30 to protect; and be conducive to so outer protection tooth 30 to make the pick that size is relatively little, cost-saving.
In order to make effectively protection external tooth 20 of outer protection tooth 30, the outer protection tooth 30 in this embodiment comprises multiple, and respectively with external tooth 20 corresponding settings one by one, as shown in Figure 2, the corresponding position of each external tooth 20 is provided with one and protects tooth 30 outward.As preferably, the outer wall vertical setting of outer protection tooth 30 and drilling pipe 10.
Dig in drilling tool drilling process owing to revolving, revolve dig drilling tool internal tooth 40 also can with rock stratum contact friction, therefore, also can there is the situation that causes the toothholder of internal tooth 40 to be worn because of eccentric wear in internal tooth 40, thereby, with reference to the structure configuration of above-mentioned outer protection tooth 30, on the inwall that revolves drilling pipe 10 bottoms of digging drilling tool of this embodiment, be also provided with interior protection tooth 50, the crown of interior protection tooth 50 is greater than the toothholder of internal tooth 40 to the vertical distance of drilling pipe 10 inwalls to the vertical distance of drilling pipe 10 inwalls, makes the effectively toothholder of protection internal tooth 40 of interior protection tooth 50; And preferably; the crown of interior protection tooth 50 is less than the crown of internal tooth 40 to the vertical distance of described drilling pipe 10 inwalls to the vertical distance of drilling pipe 10 inwalls; making full use of internal tooth 40 carries out grinding in drilling pipe 10 inside and creeps into; protection tooth 50 in protection to a certain extent; be conducive to reduce the size of interior protection tooth 50, to reduce costs.
As further preferred version, interior protection tooth 50 is preferably multiple, and with internal tooth 40 corresponding setting one by one, and vertical setting of inwall of interior protection tooth 50 and drilling pipe 10.
In order to prevent outer protection tooth 30 and/or interior protection tooth 50 from eccentric wear occurring, wearing and tearing are scrapped early, these embodiment China and foreign countries protect tooth 30 and/or interior protection tooth 50 can adopt rotary pick, outer protection tooth 30 comprises toothholder and can be rotatably set in the pick body in this toothholder, in the time that creep into grinding rock stratum, pick body can rotate, and reduces the situation of eccentric wear; Interior protection tooth 50 also can comprise toothholder and can be rotatably set in the pick body in toothholder, be configured to the rotary cutting tooth structure identical with outer protection tooth 30.
Correspondingly, the utility model also provides a kind of rotary drilling rig, and it is provided with as above revolving and digs drilling tool.This revolves and digs drilling tool and adopt above-mentioned revolving when digging drilling tool and creeping into; can effectively protect the wearing and tearing of external tooth toothholder and internal tooth toothholder; reduce the probability of changing toothholder; both increased work efficiency, and can reduce again component cost, and can guarantee to change that tooth is working properly carries out; can not occur because toothholder is worn; cause changing tooth work and more bother, even change the situation of toothholder, further increase work efficiency.
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.
