Description
Technical field
the utility model relates to oilfield wellbore tools technical field, is a kind of large scale drilling tool lifting sub.
Background technology
in modern age drilling technology, along with under the situation of drilling well production development and drilling speed, the application of large scale drilling tool is increasingly extensive.And when using at the scene, the external diameter due to these large scale drilling tools is greater than the size of rig floor mouse hole, after putting on rig floor, these large scale drilling tools can not put into mouse hole.The general method used is at present: on ground slope, connect general lifting sub in the upper end of large scale drilling tool, guy wire is hung in large scale drilling tool lower end, lifting sub uses on puffer after lanyard cover and carries large scale drilling tool to drilling floor surface, owing to rope sling position sliding to the lifting end of lifting sub, have impact on tourist bus elevator to be directly anchored on lifting sub and to mention large scale drilling tool, must large scale drilling tool load in a certain position, rig floor ramp, transfer puffer and the rope sling hung on lifting sub is displaced downwardly to tool lower portion, just can hang on tourist bus elevator after puffer being carried large scale drilling tool again, easily damage is caused to personnel and instrument during operation at the scene, there is very large operating risk.
Summary of the invention
the utility model provides a kind of large scale drilling tool lifting sub, overcomes the deficiency of above-mentioned prior art, and it can effectively solve, and existing lifting sub is easy in operation to be caused damage to personnel and instrument and there is the problem of operating risk.
the technical solution of the utility model is realized by following measures: a kind of large scale drilling tool lifting sub, comprises body; Left jointing is integrally fixed with at the left end of body, right jointing is integrally fixed with at the right-hand member of body, the external diameter of right jointing is greater than the external diameter of body, outside the right part of body, be integrally fixed with annular lug, the annular lug on body and form annular groove between right jointing; The through hole be connected with the cavity of right jointing with the cavity of left jointing is provided with vertically in body.
here is the further optimization and/or improvements to above-mentioned utility model technical scheme:
the above-mentioned left part at left jointing has external screw thread or internal thread.
the external diameter of above-mentioned right jointing right part is less than the external diameter of right jointing left part, has external screw thread or internal thread at the right part of right jointing.
the right part of above-mentioned annular lug is the inclined-plane of right low left high.
the left part of above-mentioned right jointing is left low right high inclined-plane.
the utility model reasonable and compact in structure, easy to use, by body, left jointing, right jointing and annular lug with the use of, realization is directly buckled in oily car elevator object drilling tool being put into by the utility model pit shaft after large scale drilling tool and drilling tool being mentioned again, there is safe and reliable feature, facilitate operation, reduce operating risk, improve operating efficiency.
Accompanying drawing explanation
accompanying drawing 1 is that the master of the utility model most preferred embodiment looks sectional structure schematic diagram.
coding in accompanying drawing is respectively: 1 is body, and 2 is left jointing, and 3 is right jointing, and 4 is annular lug, and 5 is annular groove, and 6 is through hole.
Detailed description of the invention
the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. determines according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this large scale drilling tool lifting sub comprises body 1; Left jointing 2 is integrally fixed with at the left end of body 1, right jointing 3 is integrally fixed with at the right-hand member of body 1, the external diameter of right jointing 3 is greater than the external diameter of body 1, outside the right part of body 1, be integrally fixed with annular lug 4, between the annular lug 4 on body 1 and right jointing 3, form annular groove 5; The through hole 6 be connected with the cavity of right jointing 3 with the cavity of left jointing 2 is provided with vertically in body 1.Like this, fastening rope sling by being formed in annular groove 5 between the annular lug 4 on body 1 and right jointing 3, carrying rope sling in process can not move upper; During use, right jointing 3 and large scale drilling tool are fixedly installed togather, rope sling is fastened in the annular groove 5 of the annular lug 4 on body 1 and formation between right jointing 3, body 1 is promoted with puffer, body 1 is raised together with large scale drilling tool and drilling tool, when being promoted to appropriate location, being more directly buckled on the utility model with tourist bus elevator, removing puffer and drilling tool is put into pit shaft safely by rope sling; Thus facilitate operation, reduce operating risk, improve operating efficiency.
according to actual needs, above-mentioned large scale drilling tool lifting sub can be made further optimization and/or improvements:
as shown in Figure 1, external screw thread or internal thread is had at the left part of left jointing 2.Like this, the installation and removal between left jointing 2 and drilling rod are convenient to.
as shown in Figure 1, the external diameter of right jointing 3 right part is less than the external diameter of right jointing 3 left part, has external screw thread or internal thread at the right part of right jointing 3.Like this, the installation and removal between right jointing 3 and large scale drilling tool are convenient to.
as shown in Figure 1, the right part of annular lug 4 is the inclined-plane of right low left high.Like this, the wearing and tearing of rope sling can be reduced.
as shown in Figure 1, the left part of right jointing 3 is left low right high inclined-plane.Like this, the wearing and tearing of rope sling can be reduced.
above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
