Description
Technical field
The present invention relates to horizontal drilling construction fields, more particularly to the ultra-deep horizontal drilling equipment with righting function.
Background technique
In tunneling and underground engineering, it usually needs it is smaller and with certain depth in underground drilling to dig out diameter with drilling machine
Wellhole, this operation are referred to as to drill.Bore operation generally includes vertical drilling and horizontal drilling, wherein in the level of long range
In bore operation, due to the influence that drill bit and drilling rod are self-possessed, the track of drilling can generate the error for deviateing design axis, i.e. drill bit
Meeting opposite drilling rod rear end in front end generates downward amount of deflection, tilts down so that the track of pore-forming generates, thus needs boring
Several centralizers are set on bar to adjust the drill bit elevation angle.
For this purpose, the patent document of Publication No. CN105735896A, which discloses, " utilizes centralizer group construction ultra-deep-water flat drill
The method in hole " adds no less than 1 rear end on the basis of conventional borehole method on the rear kelly bar of front end centralizer
Centralizer, and centralizer group is formed with front end centralizer, and rear end centralizer and front end centralizer interval are arranged, rear end centralizer
Outer diameter be less than front end centralizer outer diameter utilize the gravity of rear end centralizer to reduce the jerk value of drilling rod, drill bit in hole
Effect, between balancing drill and front end centralizer drilling rod generate downwarp amount, keep front end drill axis utmostly with design
Axis coincide, and reduces superdeep holes bore error, meets construction precision requirement.But since existing centralizer generally comprises hard righting
Device and soft centralizer, wherein the maximum drawback of hard centralizer is that size can not be adjusted, therefore be surpassed every time using hard centralizer
When deep level bore operation, the centralizer according to corresponding aperture and using at least small one and large one two kinds of models is required, if also
Need continuously to construct the different horizontal wellbore in multiple apertures when, then also need to prepare the centralizer of more polytypic, thus give equipment
Transport and job management bring many inconvenience；And soft centralizer is mostly laminated structure, on the one hand its weight is smaller, Wu Fayou
Effect plays counterweight balanced action, although on the other hand it can be adjusted according to aperture and to own dimensions, in ultra-deep-water
When flat bore operation, drill bit and drilling rod by gravity influenced it is fairly obvious so that the flexible structure of soft centralizer can not be to it
It is effectively supported, finally can still result in drilling rod and drill bit off-axis, therefore existing soft centralizer also can not be effectively
Apply to horizontal drilling operation.
Summary of the invention
For the deficiency in the presence of the prior art, the present invention provides the ultra-deep horizontal drillings with righting function to set
It is standby, it will lead to the problem of transport and management inconvenience when which solve using existing hard centralizer construction ultra-deep horizontal drilling, and adopt
It can not effectively solve the problems, such as that drilling track deviates predetermined axial line again when with existing soft centralizer construction ultra-deep horizontal drilling.
To achieve the above object, present invention employs the following technical solutions:
Ultra-deep horizontal drilling equipment with righting function including drilling rod, is fixed in drill bit and the fixation of drilling rod end
In multiple diameter-changing centering guides on drilling rod, in which:
The diameter-changing centering guide includes columnar installation part, by first rotating shaft is installed in rotation on installation part respectively
Multiple rolling members of outside and the adjusting component for being adjustably mounted on installation part and be used to control rolling member rotational angle,
The multiple rolling member is circumferentially distributed around the central axis of installation part, and the first rotating shaft is respectively perpendicular in the installation part
Mandrel.
Compared with the prior art, the invention has the following beneficial effects: when needing variable diameter, it is by the first adjusting component
Controllable rolling member rotation, and then it is made to be unfolded or shrink, finally realize that the outer profile size of the diameter-changing centering guide becomes larger
Or it reduces；When carrying out horizontal drilling operation, multiple diameter-changing centering guides are separately mounted on drilling rod, wherein near drill bit
Diameter-changing centering guide is adjusted to outer profile size and is all larger than other diameter-changing centering guides；When thus carrying out horizontal drilling operation, without standard
Standby various types of centralizers, bring great convenience, while manufacturing cost of the present invention is cheap to transportation management etc., operation side
Just, there is preferable market promotion prospect.

The adjusting component of degree, the multiple rolling member 30 are circumferentially distributed around the central axis of installation part 20, and the first rotating shaft 90 is distinguished
Perpendicular to the central axis of the installation part 20；
Specifically, the lug boss 21 of a ring shape and the protrusion are fixedly installed to the wall coaxial of the installation part 20
21 outer wall of portion is equipped with external screw thread, the split type structure that the lug boss 21 can be an integral structure or weld with installation part 20；
The adjusting component is connected through a screw thread with lug boss 21 has realized that it can be adjusted along the axial direction of installation part 20,
Specifically, it is described adjust component include be threaded on lug boss 21 and outer wall be equipped with one circle annular spacing groove 41 adjustment portion
40, it the stop collar 42 that is installed in rotation in limiting slot 41 and is hinged on by the second shaft 91 multiple on stop collar 42
The quantity of interconnecting piece 43, the interconnecting piece 43 is equal with the quantity of rolling member 30, multiple interconnecting pieces 43 and also with multiple institutes
It is one-to-one hinged by third shaft 92 respectively to state rolling member 30；The adjustment portion 40 includes that tool internal thread first is adjusted
Section set 40 and the second adjusting set 44 for being threaded in 40 one end of the first adjusting set, the internal diameter of the first adjusting set 40 are greater than drilling rod 10
Outer diameter is simultaneously threadedly coupled with the lug boss 21, and second adjusting set 44 includes set of the outer diameter less than 40 outer diameter of the first adjusting set
Body 441 and be fixedly arranged on 441 outer wall of body a ring shape limiting section 442, and outside 442 end of the limiting section, body 441
It is surrounded between 40 end of surface and the first adjusting set and forms the limiting slot 41, the internal diameter of the body 441 is greater than drilling rod 10
Outer diameter；Preferably, the blocking portion 45 that a ring shape is connected with far from 44 one end of the second adjusting set of first adjusting set 40；
The rolling member 30 includes supporting element 301 and the multiple Universal casters 302 being threaded on supporting element 301,
Two ends axial along drilling rod 10 of the supporting element 301 are provided with inclined surface 303, are equipped with ten thousand on the inclined surface 303
To ball 302, can also be in contact by Universal caster with the hole wall of drilling when guaranteeing that the rolling member 30 rotates by a certain angle.
As shown in Figures 2 and 3, the outer wall of the installation part 20 is fixedly connected with the support arm that multiple groups have the first hinge hole
22, it is preferable that every group of support arm 22 is two and its first hinge hole is coaxial arrangement, the bottom centre of the supporting element 301
