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 that comprises this arbitrary-movement articulator.
Background technology
Arbitrary-movement articulator is the vitals of rotary drilling rig.Rotary drilling rig is dropping to drill rod boring tool in the hole or is carrying in the process of brill, and arbitrary-movement articulator play the guiding role, and prevents drilling rod and surface water horizontal line deflection, causes the pore-forming axis deviation.Particularly; be rotated at rotary drilling rig and bore native operation and when needs utilize inertia to get rid of soil; run of steel drilling rod with respect to the length of unit head key plate has become cantilever lever; rigidity a little less than; easy unstability; at this time arbitrary-movement articulator is just helped and the supports drill rods other end, has protected unit head to avoid the destruction that the unstability because of drilling rod causes to a certain extent.
Existing arbitrary-movement articulator adopts parallel to each other and has the bracing frame 1 that the cover plate 4 of two supporting legs and base plate 5 and 6 weldings of the cant board between cover plate 4 and base plate 5 form respectively as shown in Figure 1.Be connected with floating bearing 2 and floating bearing 2 is connected with bolt with drilling rod at an end of bracing frame 1, two supporting legs at the other end are equipped with a pair of gathering sill 3, the guide rail that is positioned at the mast both sides of rotary drilling rig can be stuck in gathering sill 3 and leave certain motion gap, thereby utilizes the guide rail of mast to come rising and the down maneuver of drilling rod are led.
Because engineering geology has very big randomness, the soil property of pore-forming is again at deep under ground, be difficult to know in advance, the bore operation diameter that adds rotary drilling rig is big again, can make the drill rod boring tool discontinuity when drilling tool runs into the inhomogeneous sillar of hard oblique scar or 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 bracing frame 1 distortion, guide groove 3 crackings.Therefore, in the prior art, the problem that exists arbitrary-movement articulator to damage easily.
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 big.Reprocess frequently and can influence programming and economic benefit.
Summary of the invention
The purpose of this invention is to provide a kind of arbitrary-movement articulator, this arbitrary-movement articulator does not have good strength and stiffness, thereby fragile and can increase the service life.
To achieve these goals, the invention provides a kind of arbitrary-movement articulator of rotary drilling rig, floating bearing and the gathering sill that is arranged on second end of support frame as described above that described arbitrary-movement articulator comprises bracing frame and is arranged on first end of support frame as described above, wherein, support frame as described above comprises cover plate, base plate and is connected cant board between described cover plate and the described base plate in the both sides of described support member, described cover plate and described base plate in the distance of described first end less than described cover plate and the described base plate distance at described second 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, increase in the distance of the end that is provided with gathering sill by making cover plate and base plate, cant board is increased at the width of the second end, can strengthen bulk strength and the rigidity of bracing frame, thereby increase the service life.
Other features and advantages of the present invention will partly be described in detail in the specific embodiment subsequently.
