Abstract
The invention discloses a resettable sucker rod assembly structure which comprises two sucker rods and a connecting pipe (4). The connecting pipe (4) is provided with internal threads, each sucker rod comprises a cylindrical sucker rod body (1), a thread head (2) and a connecting rod (5) for connecting the sucker rod body (1) and the thread head (2), the thread heads (2) are provided with external threads matched with internal threads of the connecting pipe (4), the two sucker rods are embedded into the connecting pipe (4) from the two ends of the connecting pipe (4) through the thread heads (2) to be connected with the connecting pipe (4), the connecting rods (5) of the two sucker rods are both located in the connecting pipe (4), and elastic reset parts (6) are connected between the lateral walls of the connecting rods (5) and the inner wall of the connecting pipe (4). According to the resettable sucker rod assembly structure, the two sucker rods are connected through the connecting pipe (4), the risk of breakage of the assembly structure can be reduced by additionally arranging the elastic reset parts (6) and adopting connection in a thread matching mode, and it is guaranteed that oil exploitation can be conducted normally.
Description
Technical field
The present invention relates to the frame for movement of field of petroleum exploitation, specifically reducible sucker rod package assembly.
Background technology
In oil exploitation, be usually applied to rod pumping system, wherein, rod pumping system is mainly made up of oil pumper, sucker rod, oil well pump three parts, oil pumper is oil production equipment, sucker rod is the critical component of oil pumping system, sucker rod is used for connecting oil well pump and oil pumper, and plays the effect of transferring power.The length of single sucker rod is generally 7.6 meters or 8 meters; while adopting sucker rod to connect oil pumper and oil well pump; generally need splice many sucker rods; the sucker rod of splicing is in the time of application now; usually can there is because twisting resistance is excessive fracture in the syndeton between two sucker rods, this can have influence on the normal exploitation of oil.
Summary of the invention
The sucker rod that the object of the invention is to solve existing splicing is prone to the problem of syndeton fracture in the time of application, a kind of reducible sucker rod package assembly is provided, it is by opposing twisting resistance, and then reduce the risk that fracture appears in sucker rod connection structure, ensure normally carrying out of oil exploitation.
Object of the present invention is achieved through the following technical solutions: reducible sucker rod package assembly, comprise the tube connector of two sucker rods and circular casing shape, described tube connector is provided with internal thread, described sucker rod comprises columned sucker rod body, the connecting rod of thread head and connecting with pumping rod body and thread head, described thread head is provided with the external screw thread mating with tube connector internal thread, two sucker rods are embedded in tube connector and are connected with tube connector from tube connector two ends by thread head respectively, the connecting rod of two sucker rods is all positioned at tube connector, and be connected with elastic reset part between connecting rod sidewall and tube connector inwall.The present invention connects sucker rod by tube connector, and tube connector is in the time connecting two sucker rods, and the two ends of tube connector have all embedded sucker rod.
On described sucker rod body, be arranged with the spacing ring being positioned at outside tube connector.Wherein, the present invention limits sucker rod by spacing ring and embeds the degree of depth in tube connector.
In the time that spacing ring is subject to larger active force, embed in tube connector, the outer ring diameter of described spacing ring is greater than the internal diameter of tube connector.
Sucker rod body of the present invention, thread head and spacing ring both can become one, can connect as one by the mode of welding again, in order to strengthen the structural strength of sucker rod, improve the ability of its opposing stress, as preferably, described sucker rod body, thread head and spacing ring become one.
Because of spring be convenient to draw materials, with low cost, as preferably, described elastic reset part is spring.
Compared with prior art, the present invention has following beneficial effect: (1) the present invention includes the tube connector of two sucker rods and circular casing shape, wherein, sucker rod comprises columned sucker rod body and the thread head being connected with sucker rod body, the mode that two sucker rods all mate by screw thread is connected with tube connector, this can cushion the twisting resistance between syndeton, reduces the risk that occurs fracture when the present invention applies.
(2) connecting rod of two sucker rods of the present invention is all positioned at tube connector, between connecting rod sidewall and tube connector inwall, be connected with elastic reset part, distortion can twist when in the time of sucker rod rotary, elastic reset part is subject to twisting resistance, also can cushion twisting resistance, in the time that sucker rod is not subject to reversing, elastic reset part can drive sucker rod to reset, so, can further reduce the risk that fracture appears in package assembly of the present invention, while ensureing two sucker rods to connect, structure is firm, and then can avoid sucker rod connection structure to occur fracture and affect the normal exploitation of oil.
(3) on sucker rod body of the present invention, be arranged with the spacing ring being positioned at outside tube connector, wherein, spacing ring can play spacing and effect that bear twisting resistance, and then can strengthen the ability of resisting stress when the present invention applies.
