Description
Technical field
The present invention relates to rotary drilling rig, particularly, relate to a kind of arbitrary-movement articulator and the rotary drilling rig comprising this arbitrary-movement articulator.
Background technology
Arbitrary-movement articulator is the vitals of rotary drilling rig.Drill rod boring tool is dropping in hole or in the process carrying brill by rotary drilling rig, and arbitrary-movement articulator play the guiding role, and prevents drilling rod and surface water horizontal line deflection, causes pore-forming axis deviation.Particularly; the operation and when needs utilize inertia to get rid of soil of rotary drilling soil is carried out at rotary drilling rig; run of steel relative to power head key plate length drilling rod become cantilever lever; rigidity is more weak; easy unstability; at this time arbitrary-movement articulator is just helped and the supports drill rods other end, protects the destruction that unit head causes from the unstability because of drilling rod to a certain extent.
Existing arbitrary-movement articulator as shown in Figure 1, adopts parallel to each other and has the cover plate 4 of two supporting legs and the bracing frame 1 of base plate 5 and the cant board between cover plate 4 and base plate 56 welding respectively.Floating bearing 2 is connected with and floating bearing 2 is connected with drilling rod bolt in one end of bracing frame 1, two supporting legs of the other end are provided with a pair gathering sill 3, the guide rail being positioned at the mast both sides of rotary drilling rig can be stuck in gathering sill 3 and leave certain motion gap, thus utilizes the guide rail of mast to lead to the rising of drilling rod and down maneuver.
Because engineering geology has very large randomness, the soil property of pore-forming is again at deep under ground, be difficult to know in advance, add that the bore operation diameter of rotary drilling rig is large again, can make drill rod boring tool discontinuity when drilling tool runs into hard oblique scar or the uneven sillar of stress field, it is frequent that this causes arbitrary-movement articulator to damage in actual site operation process.The main failure forms of arbitrary-movement articulator is that bracing frame 1 is out of shape, guide groove 3 ftractures.Therefore, in prior art, there is arbitrary-movement articulator and hold flimsy problem.
In addition, because arbitrary-movement articulator is arranged on the mast top of rotary drilling rig, and adopt a fairly large number of bolt to be connected with drilling rod, its dismounting difficulty is large.Reprocess and frequently can affect programming and economic benefit.
Summary of the invention
The object of this invention is to provide a kind of arbitrary-movement articulator, this arbitrary-movement articulator does not have good strength and stiffness, thus fragile and can increase the service life.
To achieve these goals, the invention provides a kind of arbitrary-movement articulator of rotary drilling rig, described arbitrary-movement articulator comprise bracing frame and be arranged on support frame as described above first end floating bearing and be arranged on the gathering sill of the second end of support frame as described above, wherein, support frame as described above comprises cover plate, base plate and the both sides at support frame as described above and is connected to cant board between described cover plate and described base plate, and described cover plate and described base plate are less than described cover plate and the described base plate distance at described second end in the distance of described first end.
The present invention also provides a kind of rotary drilling rig, and wherein, this rotary drilling rig comprises arbitrary-movement articulator of the present invention.
By technique scheme, by making cover plate and base plate increase in the distance of the end being provided with gathering sill, namely making cant board increase at the width of the second end, bulk strength and the rigidity of bracing frame can be strengthened, thus increase the service life.
Other features and advantages of the present invention are described in detail in detailed description of the invention part subsequently.
