Abstract
The utility model belongs to the technical field of rotary drill machinery equipment, and particularly relates to a screw type stabilizer on a rotary drill, comprising a rotary drill stabilizer. The stabilizer is characterized in that three linear rib plates are uniformly arranged along the periphery of the outer surface of the rotary drill stabilizer, and the linear rib plates are obliquely arranged along the axis. According to the screw type stabilizer, as the three obliquely arranged linear rib plates are arranged on the stabilizer, a screw rib plate structure is formed, slots on two ends of a traditional rib plate are eliminated, and the structure is enabled to be more stable. Soil slag produced in the site operation is discharged along the direction of a screw type rib plate, so that the soil slag is uneasy to pile up, the friction and the resistance between slag and a drill stem are reduced, and the drilling effect is more perfect.
Description
Technical field
The utility model belongs to the rotary drill mechanical equipment technical field, especially relates to the spiral virtual calibrator for instrument transformer on a kind of rotary drill.
Background technology
At present, the employed rotary drill virtual calibrator for instrument transformer in mine is in use because the slag phenomenon often appears suppressing in original design defect, its main cause: the gusset of original rotary drill virtual calibrator for instrument transformer in axial direction arranges, and the gusset two ends are provided with the twice groove, during field operation, the foreign material such as soil slag often are deposited in can not in time be got rid of herein, and virtual calibrator for instrument transformer is walked around moving with per minute 80-90, cause herein serious wear of virtual calibrator for instrument transformer, virtual calibrator for instrument transformer is worn into calabash shape easily after work a period of time, change and untimelyly will cause radial fragmentation, thereby cause roller cone drilling machine drill head to come off or produce the heavy losses such as useless hole.
Summary of the invention
The purpose of this utility model provides a kind of stable, stabilized structure, the spiral virtual calibrator for instrument transformer on the rotary drill of long service life.
The purpose of this utility model realizes by following technical proposals:
Spiral virtual calibrator for instrument transformer on the rotary drill of the present utility model, the virtual calibrator for instrument transformer body that comprises rotary drill, it is characterized in that along even circumferential three linear gussets being set at the external surface of the virtual calibrator for instrument transformer body of described rotary drill, described linear gusset is obliquely installed vertically.
Described linear gusset is 8 with axial angle
0-15
0
Advantage of the present utility model:
Because three linear gussets that are obliquely installed have been combined to form spiral reinforcing plate structure on the utility model virtual calibrator for instrument transformer, and have cancelled the groove at original gusset two ends, make structure more firm.The native slag that site work produces can be discharged along the direction of spiral gusset, is difficult for piling up, and reduces friction and the resistance of bits and drilling rod, and the effect of perforation is more perfect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A view of the utility model Fig. 1.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2, spiral virtual calibrator for instrument transformer on a kind of rotary drill, the virtual calibrator for instrument transformer body 2 that comprises rotary drill is characterized in that along even circumferential three linear gussets 1 being set at the external surface of the virtual calibrator for instrument transformer body 2 of described rotary drill, and described linear gusset 1 is obliquely installed vertically.Described linear gusset 1 is 8 with axial angle
0-15
0Three linear gussets 1 that are obliquely installed are looped around the external surface of rotary drill virtual calibrator for instrument transformer 2, form spiral gusset, cancelled simultaneously the groove at original gusset two ends, in operation process, the grinding hole wall produces the continuity grinding, the slag of grinding process is not to produce simultaneously, slag, native slag etc. are blown out outside the hole by high-pressure blast at any time, the bits that are blown produce rotation (along the forward direction rotation of drilling rod) in moment, and discharge along the direction of spiral rib plate, be difficult for piling up, reduce friction and the resistance of bits and drilling rod, the effect of perforation is more perfect.
Claims (2)
1. the spiral virtual calibrator for instrument transformer on the rotary drill comprises the virtual calibrator for instrument transformer body of rotary drill, it is characterized in that along even circumferential three linear gussets being set at the external surface of the virtual calibrator for instrument transformer body of described rotary drill, and described linear gusset is obliquely installed vertically.
2. the spiral virtual calibrator for instrument transformer on the rotary drill according to claim 1 is characterized in that described linear gusset and axial angle are 8
