Abstract
The present invention provides a kind of sucker rod with wear automatic-compensation structure.The present invention includes oil pumping bar body, it is characterized in that：Axially spaced one section is provided with one group of bar shaped fixed lobe in described oil pumping bar body, described bar shaped fixed lobe is evenly distributed on the periphery of described oil pumping bar body, clamp wear rib between adjacent described bar shaped fixed lobe, compression spring is provided between described wear rib and described oil pumping bar body, the oil-through hole with the axis parallel of described oil pumping bar body is provided with each described bar shaped fixed lobe.The present invention can be compensated automatically after damaging occurs in wearing layer, and extend the service life and maintenance period of sucker rod.
Description
Technical field：
The present invention relates to a kind of sucker rod with wear automatic-compensation structure, belong to technical field of petroleum machinery.
Background technology：
Oil pumper used in oil extraction in oil field is that, by a kind of up and down motion for laying particular stress on leverage (being commonly called as horse head machine), drive is taken out mostly
Beam hanger is moved back and forth, and completes Pumping action.Sucker rod is formed by the threaded connection of multistage bar, and sucker rod is curved in oil recovery process
Bent and cause the pressure friction with oil pipe to be inevitable due to bending, the solution generally used is on sucker rod
Several friction prevention devices (centralizer) are installed, friction prevention device is made of the material less than sucker rod, oil pipe hardness, external diameter and the oil of friction prevention device
There is less gap in pore footpath, thus, and friction prevention device can both play the centralizing function to sucker rod, can protect or reduce again oil pumping
The abrasion of bar.At present, wearing layer is mainly directly sleeved in sucker rod anti-abrasion device main body by used sucker rod anti-abrasion device
Portion.The sucker rod anti-abrasion device of this structure when in use, is primarily present problems with：In oil pumping process, sucker rod anti-abrasion device is long
Time uses, and wearing layer will loosen, and influence coordinates, it is impossible to meets abrasionproof effect, or even can cause sucker rod and oil pumping
The damage of pipe；After wearing layer is fixed with sucker rod anti-abrasion device main body, just inconvenient demolition and maintenance, use cost is just high.
The content of the invention：
The purpose of the present invention is to provide a kind of sucker rod with wear automatic-compensation structure for above-mentioned problem, resistance to
Compensating automatically after damaging occurs in mill layer, and extends the service life and maintenance period of sucker rod.
Above-mentioned purpose is realized by following technical scheme：
It is axially spaced in sucker rod with wear automatic-compensation structure, including oil pumping bar body, described oil pumping bar body
One section is provided with one group of bar shaped fixed lobe, and described bar shaped fixed lobe is evenly distributed on the outer of described oil pumping bar body
Clamp wear rib between week, adjacent described bar shaped fixed lobe, between described wear rib and described oil pumping bar body
Compression spring is provided with, the mistake with the axis parallel of described oil pumping bar body is provided with each described bar shaped fixed lobe
Oilhole.
The described sucker rod with wear automatic-compensation structure, the outside of each described bar shaped fixed lobe is provided with
Cross oil groove.
The described sucker rod with wear automatic-compensation structure, between wear rib described in every and described sucker rod
Compression spring be provided with least two.
The described sucker rod with wear automatic-compensation structure, the bar shaped fixed lobe described in every group is no less than three.
The described sucker rod with wear automatic-compensation structure, described strip fixed lobe and described sucker rod sheet
Body is formed using integrated poured.
The described sucker rod with wear automatic-compensation structure, described oil pumping bar body is upper in the bar described in every group
Shape fixed lobe is provided at both ends with wear rib stop nut.
Beneficial effect：
1. wear body is designed into strips and is embedded between the strip fixed lobe in oil pumping bar body by the present invention, and passes through bullet
Spring realizes the automatic compensation of abrasion, so as to substantially prolongs the service life and maintenance period of sucker rod.
2. the outside of each described bar shaped fixed lobe of the present invention was provided with oil groove, it is easy to oil to pass through.
3. the compression spring between wear rib and described sucker rod described in every of the present invention is provided with least two,
Uniform force, it is stable and reliable in work.
4. the strip fixed lobe of the present invention is formed with described oil pumping bar body using integrated poured, structure is more steady
Fixed, service life is long.
5. the present invention is provided at both ends with wear rib limit the oil pumping upper bar shaped fixed lobe in described in every group of bar body
Position nut, effectively prevent wear rib axial float.
Brief description of the drawings：
Fig. 1 is the structural representation of the present invention.
Fig. 2 is Fig. 1 A-A profiles.
1 in figure, oil pumping bar body；2nd, bar shaped fixed lobe；3rd, wear rib；4th, compression spring；5th, oil-through hole；6th, it is excessively oily
Groove；7th, wear rib stop nut.
Embodiment：
Embodiment 1：
As shown in Figure 1：The sucker rod with wear automatic-compensation structure of the present embodiment, including oil pumping bar body 1, described takes out
Axially spaced one section is provided with one group of bar shaped fixed lobe 2 on beam hanger body, and described bar shaped fixed lobe is evenly distributed on
Clamp wear rib 3 between the periphery of described oil pumping bar body, adjacent described bar shaped fixed lobe, described wear rib with
Compression spring 4 is provided between described oil pumping bar body, is provided with and is taken out with described on each described bar shaped fixed lobe
The oil-through hole 5 of the axis parallel of beam hanger body.
The sucker rod with wear automatic-compensation structure described in the present embodiment, each described bar shaped fixed lobe
Outside was provided with oil groove 6, was easy to oil to pass through.
The sucker rod with wear automatic-compensation structure described in the present embodiment, wear rib described in every with it is described
Compression spring between sucker rod is provided with least two.Two compression springs are symmetricly set under the two ends of each wear rib
Side, when wear rib weares and teares, spring is compensated wear rib toward going out to push away certain push-in stroke automatically, keeps wear rib and oil pumping
The contact of pipe.
The sucker rod with wear automatic-compensation structure described in the present embodiment, the bar shaped fixed lobe described in every group is not
Less than three.
The sucker rod with wear automatic-compensation structure described in the present embodiment, described strip fixed lobe with it is described
Oil pumping bar body formed using integrated poured, structure is more stablized, and service life is long.
