Description
Technical field
It the utility model is related to mine drilling equipment technical field, and in particular to a kind of drill rod stabilizing device.
Background technology
At present, known drill rod stabilizing device is all to increase a kind of stabilising arrangement, this stabilization between drilling rod and drill bit
The overall diameter of device is slightly less than drill bit, can provide a stable center for the drill bit in drilling process and drilling rod, prevent drill bit
Rock and cause hole scattering；But these additional stabilising arrangements are rotated with drill bit and drilling rod, add power
The load of device and the rate of wear for accelerating stabilising arrangement.
Utility model content
For problem above, the utility model aims to provide a kind of simple in construction, easy to operate, good drilling rod of stablizing effect
Stabilising arrangement.
To achieve these goals, the utility model uses following technical scheme：
A kind of drill rod stabilizing device, including front uniting part, stable body and rear coupling part, stable body include axle
Hold, be provided with teeth groove in bearing, bearing outside surface is uniformly distributed four vane arms, and each vane arm is provided with a blade, described
Blade is in borehole axial and is radially provided with radian；Coupling part is the cylindrical structural of inner hollow afterwards, and its inner surface is provided with
Internal thread；Front uniting part includes the cylinder of two inner hollows of size, and the end of the big cylinder, which is provided with, to be used to connect
Connect the first external screw thread line of drill bit, one end of small cylinder is provided with square shaped teeth, and the other end is provided with for stable connection body
Two external screw thread lines.
The end of coupling part is provided with the first circular protrusions afterwards.
Square shaped teeth and the junction of big cylinder are provided with the second circular protrusions in front uniting part.
The distance of two described symmetrical blades is less than bit diameter.
Described blade and the material of bearing are Hi-Stren steel.
By above technical scheme, the beneficial effects of the utility model are：
The steady component of drill rod stabilizing device provided by the utility model does not rotate with drill bit and drilling rod, can effectively subtract
Delay its rate of wear, required kinetic energy is less than existing apparatus, and simple in construction, easy disassembling, and simple to operate, stablizing effect is good, bores
Enter efficiency high, and hole wall can be played a supporting role to a certain extent.

Fig. 1 is the utility model schematic diagram.
Fig. 2 is front uniting part structural representation.
Fig. 3 is steady component structural representation.
Fig. 4 is I-I profile of steady component.
Fig. 5 is rear coupling part structural representation.
Embodiment
As shown in accompanying drawing 1-5, a kind of drill rod stabilizing device, including front uniting part, stable body and rear coupling part, surely
Fixed part mainly provides a point of safes for drilling equipment, is not rotated with drilling equipment.Stable body includes bearing 2,
Teeth groove 6 is provided with bearing 2, the outer surface of bearing 2 is uniformly distributed four vane arms, and each vane arm is provided with a blade 1, blade
1 borehole axial and is being radially provided with radian, and blade 1 facilitates whole device to be moved along borehole axial in axially arranged radian, leaf
Piece 1 is radially being also provided with certain radian, and to match with borehole shape, but its radian is unsuitable excessive in order to avoid influence deslagging；
Coupling part is the cylindrical structural of inner hollow afterwards, and its inner surface is provided with internal thread 7；Front uniting part includes size two
The cylinder of individual inner hollow, the end of big cylinder are provided with the first external screw thread line 4 for being used for connecting drill bit, and the one of small cylinder
End is provided with square shaped teeth 3, and square shaped teeth 3 is caught in the teeth groove 6 in bearing 2, and then makes to stablize body and be connected with front uniting part, small
The cylinder other end is provided with the second external screw thread line 41 for coupling part after connecting.
The end of coupling part is provided with the first circular protrusions 8 afterwards.
Square shaped teeth and the junction of big cylinder are provided with the second circular protrusions 5 in front uniting part, for restricted stability portion
Divide the movement in borehole axial direction.
The distance of two symmetrical blades 1 is less than bit diameter, prevents blade 1 and drill bit from rubbing.
The material of blade 1 and bearing 2 is Hi-Stren steel, and during due to being drilled in rock stratum, environment compares in drilling
Badly, situation is more complicated, therefore must can bear certain impact using the high and wear-resisting material of intensity.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
The scope of protection of the utility model.
