Abstract
The utility model relates to a locked pumping rod with reasonable structure, reliable performance, easy installation, big transmission torque and operations in both positive and negative directions. The preferred technical proposal is that a rod body of the locked pumping rod has a separate structure and comprises a plurality of rods connected with each other in turn; a connecting part between every two adjacent rods comprises an upper rod connector and a lower rod connector arranged on the two adjacent rods separately and sleeves arranged on the outer surfaces of the upper connector and lower connector; the section plane profiles of the connecting positions of the upper and lower connectors are polygons; the inner hole profile of the sleeve matches the section plane profile of the connecting positions of the upper and lower connectors; and axial spacing units of the sleeves are axially arranged on the upper and lower connectors. The section plane profiles of the connecting positions of the upper and lower connectors are quadrangles or a close figure composed of arcs and straight lines. The axial positioning structure at one sleeve end is a shaft collar and the axial positioning structure at another sleeve end is a clamp spring.
Description
Technical field
The utility model relates to a kind of oil field oil production technology complete sets of Techniques instrument, relates in particular to a kind of anticreep sucker rod.
Background technology
At present, the used sucker rod of bar driven screw pump oil recovery can be divided into common sucker rod, awl button sucker rod and three kinds of forms of plug-in type sucker rod, preceding two kinds of sucker rods are to come transfer torque by the mode that is threaded, can be on a direction of rotation transfer torque, easy to connect, but when work, thread off easily, need very big shackle moment of torsion during maintenance; The characteristics of not threading off when the plug-in type sucker rod has work, come transfer torque with interface between sucker rod, this kind inserting mode in theory can be on two direction of rotation transfer torque, but actually can only turn to transfer torque at one, when being used for another direction transfer torque, rod collar releases easily and causes pumping rod disengaging, and has certain degree of difficulty in processing, and it is convenient inadequately to install; It is a technical problem that urgent need overcomes in bar driven screw pump oil recovery technique that the sucker rod that often occurs in the above-mentioned prior art such as breaks, takes off at technical barrier, need on the market a kind of rational in infrastructure, easy for installation, have a good reliability, again can be on two direction of rotation the sucker rod of transfer torque.Research and develop a kind of anticreep, disconnected, and work that can the transmitting large torque sucker rod has very important realistic meaning.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, but the utility model provide a kind of rational in infrastructure, reliable operation, easy for installation, transfer torque is big, forward and reverse all anticreep sucker rods of operate as normal.
In order to solve the problems of the technologies described above, the technical scheme that the utility model is achieved is, the body of rod of anticreep sucker rod is for dividing body structure, be the many bars structure that connects successively, the connector between per two adjacent bars is made of last knock-off joint, time knock-off joint of adjacent stems and the sleeve that is arranged on the upper and lower knock-off joint external surface; Described upper and lower knock-off joint connecting portion section be shaped as polygon, the interior hole shape of described sleeve and described upper and lower knock-off joint connecting portion section shape coincide, described upper and lower knock-off joint is provided with the axial positioning structure of sleeve.
The utility model anticreep sucker rod, wherein, described upper and lower knock-off joint connecting portion section be shaped as quadrangle or by the closed figure of circular arc and rectilinear(-al).The axial positioning structure of described sleeve one end is a shaft shoulder structure, and the axial positioning structure of the described sleeve other end is the jump ring structure.
Compared with prior art, the beneficial effect that the utility model had is:
(1) the utility model anticreep sucker rod has function rational in infrastructure, easy for installation;
(2) can transmitting large torque moment, overcome that the sucker rod that is often caused because of transmitting large torque moment in the prior art disconnects, the dropout phenomenon;
(3) can be implemented in transfer torque on positive and negative two direction of rotation.

The specific embodiment
Below in conjunction with accompanying drawing the utility model sound integrated form blender is done and to be described in further detail.
As shown in Figure 1, the utility model anticreep sucker rod is a minute body structure, is made up of the many bars that connect successively, is provided with connector 3 between per two adjacent bars; Described connector 3 is made of the upper and lower knock-off joint 4,5 of adjacent stems and the sleeve 6 that is arranged on upper and lower knock-off joint 4,5 cylindricals, as shown in Figures 2 and 3, the described section shape of going up the connecting portion of knock-off joint 4 and following knock-off joint 5 is a polygon, be illustrated as hexagon, also can be quadrangle, or on the basis of cylinder, milling the closed figure of flat back formation by circular arc and rectilinear(-al), hole shapes and described upper and lower knock-off joint connecting portion section shape coincide in the described sleeve 6.As shown in Figure 4, described upward knock-off joint 4 and following knock-off joint 5 joints are for being threaded.Cause coming off, separating of upper boom 1 and lower beam 2 in order to prevent sleeve 6 from sliding, the two ends of described sleeve 6 are provided with location structure, the axial positioning structure of described sleeve 6 one ends is a shaft shoulder structure, and the axial positioning structure of described sleeve 6 other ends is jump ring 8 structures or other axial positioning structure.Under the situation that guarantees performance indications such as strength of oil pump rod and rigidity, when adopting hollow-core construction, then need between described upper and lower bar contact surface, be provided with seal as if described upper and lower bar.When the sucker rod of selecting for use was hollow-core construction, seal sealed, and can prevent effectively that well liquid from entering in the hollow rod.
When the utility model anticreep sucker rod is installed, at first, with being threaded of last knock-off joint 4 and following knock-off joint 5 butted parts, then sleeve 6 is enclosed within on the cylindrical at upper and lower knock-off joint place, card is gone up jump ring 8 at last.The moment of torsion on described sucker rod top passes to the sucker rod of bottom by the screw thread of upper and lower knock-off joint junction.Because, no matter adopt polygon shaft, cover to be connected between sleeve 6 and upper and lower knock-off joint 4 and 5 respectively, be the forward and reverse moment of torsion of transmission, break-off can not take place, therefore, the utility model anticreep sucker rod can transmit the moment of torsion of positive and negative both direction reliably.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also design a lot of forms, these all belong within the protection of the present utility model.
