Abstract
The utility model discloses a kind of drilling rod of anti-offset whipping, including multiple drilling rods linearly to connect vertically, suit is fixed with an axle sleeve outside the junction of every two adjacent drill pipes, and the axle sleeve is in be coaxially disposed with drilling rod, the bearing for being fixed with and being in contact with drilling inner ring surface is set with outside described axle sleeve, and the bearing is also in be coaxially disposed with axle sleeve.Using said structure, by being engaged for the bearing and drilling inner ring surface, centralizing function can be played to drilling rod, and can effectively avoid drilling rod from occurring skew whipping in drilling process.
Description
Technical field
It the utility model is related to geological drilling technology field, and in particular to a kind of drilling rod of anti-offset whipping.
Background technology
According to the requirement of architecture foundation pile inspection specifications, the perpendicularity deviation of drilling not should be greater than 0.5% typically.But with
The increase of drilling depth, the slenderness ratio of drilling rod increase with the increase of drilling depth, and drilling rod is overall by rigidly switching to flexibility, bores
Increase during entering with the eccentric of rotation drilling rod of drilling tool, so as to cause drilling hole deviation increase, and then cause the too early deviation that drills
Pile body.
If energy keyhole perpendicularity, reducing eccentric drilling, it just can effectively ensure the perpendicularity of drilling, for this
Problem is usually that righting stabilizer is installed on drilling rod in the market to ensure the perpendicularity of drilling, but because righting is stable
Device does not keep contacting with drilling inner ring surface, therefore in the case where drilling depth is larger, whipping still occurs in drilling rod.
The content of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of drilling rod of anti-offset whipping.
To achieve the above object, the utility model provides a kind of drilling rod of anti-offset whipping, including multiple lines vertically
Property the drilling rod that connects, suit is fixed with an axle sleeve outside the junction of every two adjacent drill pipes, and the axle sleeve is in coaxial with drilling rod
Set, the bearing for being fixed with and being in contact with drilling inner ring surface is set with outside described axle sleeve, and the bearing is also in coaxial with axle sleeve
Set.
The beneficial effects of the utility model are：Using said structure, due to the utility model outside drilling rod coaxial package
Axle sleeve, and coaxial sleeve is equipped with the bearing being in contact with drilling inner ring surface outside the axle sleeve, therefore pass through the bearing and drilling
Inner ring surface is engaged, and centralizing function can be played to drilling rod, and can effectively be avoided drilling rod from occurring skew in drilling process and be got rid of
It is dynamic.In addition, to adapt to the requirement of drilling depth, multiple drilling rods are linearly to connect to forming vertically, therefore the axle sleeve is set with
It is fixed on outside the junction of two adjacent drill pipes, moreover it is possible to protection is formed to the junction of two adjacent drill pipes, enables multiple drilling rods more
Solid and reliable links into an integrated entity.
The utility model can be further arranged between the axle sleeve and corresponding two adjacent drill pipes be connected through a screw thread admittedly
It is fixed.In this way, be not only connected firmly, and it is easy to disassemble.
The utility model, which may further be provided, is provided with taper projection, the brill on the axial one end for the drilling rod
The cone tank inserted for the taper projection in adjacent drill pipes, and taper projection and cone tank are provided with axial the other end of bar
Between be connected through a screw thread fixation, the taper projection, cone tank are coaxially disposed with drilling rod.In this way, not only connection is firm
It is Gu and easy to disassemble.
The utility model may further be provided is located at corresponding two adjacent drilling rod junctions axially below for the bearing.
In this way, more reasonable structure, stability is more preferable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of drilling rod of anti-offset whipping, including multiple drilling rods 1 linearly to connect vertically are given as shown in Figure 1, often
Suit is fixed with an axle sleeve 2 outside the junction of two adjacent drill pipes 1, and the axle sleeve 2 is in be coaxially disposed with drilling rod 1, the axle
Fixation is connected through a screw thread between set 2 and corresponding two adjacent drill pipes 1.It is set with and is fixed with and drilling inner ring outside described axle sleeve 2
The bearing 4 that face 3 is in contact, and the bearing 4 is also in be coaxially disposed with axle sleeve 2.The bearing 4 is located at corresponding two adjacent drill pipes 1
Junction is axially below.Taper projection 11 is provided with the axial one end of the drilling rod 1, the axial direction of the drilling rod 1 is another
Be provided with the cone tank 12 inserted for the taper projection 11 in adjacent drill pipes 1 on end, and taper projection 11 and cone tank 12 it
Between be connected through a screw thread fixation, the taper projection 11, cone tank 12 are coaxially disposed with drilling rod 1.
Using said structure, due to the utility model in 1 outer coaxial package of drilling rod axle sleeve 2, it is and same outside the axle sleeve 2
Axle sleeve be equipped with the bearing 4 that is in contact of drilling inner ring surface 3, therefore being engaged by the bearing 4 and the inner ring surface 3 that drills,
Centralizing function can be played to drilling rod 1, and can effectively avoid drilling rod 1 from occurring offseting whipping in drilling process.In addition, to adapt to bore
The requirement of hole depth, multiple drilling rods 1 are linearly to connect to forming vertically, therefore the axle sleeve 2 suit is fixed on into two adjacent brills
Outside the junction of bar 1, moreover it is possible to form protection to the junction of two adjacent drill pipes 1, enable the more solid and reliable company of multiple drilling rods 1
It is connected into one.
Claims (4)
