Abstract
The variable buckle joint of the sucker rod is applied to the threaded connection of two sucker rods with different straight diameters in the rod column combination of the oil field oil pump. The body is cylindrical, one end of the body is provided with a truncated cone, the diameter of the large end of the truncated cone is the same as the outer diameter of the body, and the body and the truncated cone are integrated; the body is internally provided with a large-diameter internal thread, and the truncated cone is internally provided with a small-diameter internal thread; the central line of the large-diameter internal thread and the central line of the small-diameter internal thread are on the same straight line; the nominal diameter of the large-diameter internal thread is 26.9-38 mm; the nominal diameter of the small-diameter internal thread is 23.8-34.9 mm. The effect is as follows: the sucker rod threaded connection that enables two kinds of different straight diameters reduces material cost, subducts the not up to standard risk of artifical breakout tongs upper thread moment of torsion, and the sucker rod specification that outward appearance distinguishable can be connected improves the construction speed, reduces intensity of labour.
Description
Technical field
The utility model relates to oil exploitation rig tool technical field, and two ends connect the change snapping head of two kinds of different-diameter sucker rods in particularly a kind of oil well pump roofbolt combination.
Background technology
The cartridge type oil well pump is a conventional machinery in the oil producing operation, and model is that 38 cartridge type oil well pump is a common type wherein.In the rod string combination that cartridge type oil pumping top connects, the pull bar diameter that the 38mm piston top of cartridge type oil pumping connects is 15.9mm, and the external thread diameter of pull bar is that 23.8mm. weighted lever diameter is 25.4mm, and the external thread diameter of weighted lever is 34.9mm.Like this, in the rod string combination, it is many to become the button combiner, causes the cost waste; Become the main pincers back-up tong spacing that the button pattern length surpasses hydraulic tongs, so the method that the artificial pipe wrench of field by using links closely because interpersonal physical difference causes torque wrench moment risk not up to standard to exist, becomes the major reason that roofbolt is threaded off.
The utility model content
The purpose of the utility model is: the change snapping head that a kind of sucker rod is provided; Can in the sucker rod combination, connect cartridge type swabs, pull bar and weighted lever successively; Large and small diameter is taken out bar and is directly connected through becoming the snapping head, reduces material cost, subdues artificial pipe wrench torque wrench moment risk not up to standard; Improve speed of application, reduce labour intensity.
The technical scheme that the utility model adopts is: the change snapping head of sucker rod; Comprise body and circular cone stage body, it is characterized in that: body is the cylinder bodily form, at an end of body the circular cone stage body is arranged; The diameter of the big end of circular cone stage body is identical with the external diameter of body, and body and circular cone stage body are one; Large diameter and inner thread is arranged in the body, the minor diameter internal thread is arranged in the circular cone stage body; The center line of the center line of large diameter and inner thread and minor diameter internal thread is on same straight line; The nominal diameter of described large diameter and inner thread is between 26.9mm～38mm; The nominal diameter of minor diameter internal thread is between 23.8mm～34.9mm.
In order to discern the sucker rod connection that the minor diameter internal thread can adapt to that a kind of specification from appearance, the box cupling external diameter of the sucker rod that the length of described circular cone stage body is connected with the minor diameter internal thread equates.
The use of the change snapping head of summary sucker rod helps to understand the utility model.The minor diameter internal thread of the change snapping head of sucker rod connects the external screw thread of minor diameter sucker rod; Large diameter and inner thread connects the external screw thread of large-diameter extraction beam hanger; The master of hydraulic tongs, back-up tong tooth tighten spanner side's diameter of large and small diameter sucker rod respectively, and the main pincers of rotation make internal and external screw thread combine to reach the standard tightening torque.
The beneficial effect of the utility model: the change snapping head of the utility model sucker rod; The sucker rod of two kinds of difference diameters is threaded; Reduce material cost, subdue artificial pipe wrench torque wrench moment risk not up to standard, appearance can be discerned the sucker rod specification that can connect; Improve speed of application, reduce labour intensity.
Description of drawings
Fig. 1 is the change snapping header structure generalized section of the utility model sucker rod.
Among the figure, 1-body, 2-circular cone stage body, 3-large diameter and inner thread, 4-minor diameter internal thread.
The specific embodiment
Embodiment 1: be applicable to that with one nominal diameter is that 15.9mm and nominal diameter are that the change snapping head of the sucker rod of 25.4mm is an example, does further explain to the utility model.
Consult Fig. 1.The change snapping head of the utility model sucker rod comprises body 1 and circular cone stage body 2.Body 1 is the cylinder bodily form, and body 1 is 55 millimeters of external diameters, and the length of body 1 is 101 millimeters, and material is 25 chrome molybdenums.End at body 1 has circular cone stage body 2, and the diameter of circular cone stage body 2 larger diameter end is identical with the external diameter of body 1, and circular cone stage body 2 length are 38 millimeters, and circular cone stage body 2 smaller diameter end diameters are 38 millimeters.Body 1 is an one with circular cone stage body 2.Large diameter and inner thread 3 is arranged in the body 1, minor diameter internal thread 4 is arranged in the circular cone stage body 2.The center line of the center line of large diameter and inner thread 3 and minor diameter internal thread 4 is on same straight line.The nominal diameter of described large diameter and inner thread 3 is 34.9mm, and the length of large diameter and inner thread 3 is 46 millimeters; The nominal diameter of minor diameter internal thread 4 is 23.8mm, and the screw thread length of minor diameter internal thread 4 is 30 millimeters.The box cupling external diameter of the sucker rod that minor diameter internal thread 4 connects is 38 millimeters.
What all the other process technologies required common rod collar requires identically, and what promptly carry out is the SY/T5029-2006 standard.
