The utility model discloses a centralizer adopts the split type design of detachable, installs in the time of both can putting into production, can install when the construction again, uses the convenience to obtain the reinforcing, centralizer and sucker rod fixed connection are right effectually, the utility model discloses a production degree of difficulty is little, and low in production cost has better economic value.
Description
Technical field
This utility model belongs to oil recovery sucker rod technical field, particularly relates to a kind of carbon fibre pumping rod with erection device.
Background technology
Sucker rod is the instrument of a kind of indispensability in oil recovery technique.By screw thread, many sucker rod first places are connected formation during use to pump
Roofbolt.When actually used, the box cupling of sucker rod can be with oil pipe friction, in the course of time, can form serious eccentric wear phenomenon,
Causing box cupling to damage eventually, Joint failure, accordingly, it would be desirable to be set with centralizer to carry out righting on sucker rod.Prior art uses
Centralizer be typically to install when construction, easy for installation, but this centralizer can be along the upper and lower vibration of sucker rod, righting effect
Bad.Also having some to carry the sucker rod of centralizer, centralizer thereon is connected as a single entity when producing with sucker rod, this oil pumping
Bar production difficulty is big, cost is high, and economic benefits comparison is poor.
Summary of the invention
This utility model provides a kind of carbon fibre pumping rod with erection device, with the problem solving to propose in above-mentioned background technology.
This utility model is solved the technical problem that and is realized by the following technical solutions: this utility model provides a kind of with holding up
The carbon fibre pumping rod of equipment, including sucker rod body and box cupling, sucker rod body is the sky being made up of carbon fibre composite
Core structure, the two-end structure of sucker rod body is identical, all includes joint, spanner gripping section and centralizer, and box cupling is by screw thread even
Being connected on joint, it is semicircular projection that position corresponding with centralizer on sucker rod body is provided with one section of cross section, centralizer
By being fixed on sucker rod body with protruding coordinating.
Described centralizer is made up of two parts, and two parts mate with the outside of sucker rod body after fastening.Two parts of centralizer
Being connected by screw, junction realizes location by the cooperation of positioning cylinder and hole, location.Described centralizer is by nylon material system
Become.The outside of described centralizer is provided with scrapes wax pan.
The beneficial effects of the utility model are: centralizer of the present utility model uses dismountable split-type design, both can give birth to
Installing during product, can install when construction again, property easy to use is strengthened；Centralizer is fixing with sucker rod to be connected, righting
Effective；Production difficulty of the present utility model is little, and production cost is low, has preferable economic worth.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the sectional view in Fig. 1 at A；
Fig. 3 is the structural representation of sucker rod body.
In figure: 1-sucker rod body, 2-centralizer, 3-spanner gripping section, 4-joint, 5-box cupling, 6-scrapes wax pan, and 7-is protruding,
8-screw, 9-positioning cylinder.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further:
Present embodiments provide a kind of carbon fibre pumping rod with erection device, including sucker rod body 1 and box cupling 5, oil pumping
Bar body 1 is the hollow-core construction being made up of carbon fibre composite, and the tension that carbon fibre composite can be effectively improved sucker rod is strong
Degree, hollow-core construction not only can alleviate the weight of sucker rod, be also beneficial to realize the functions such as dosing, well-flushing.
The two-end structure of sucker rod body 1 is identical, all includes joint 4, spanner gripping section 3 and centralizer 2, and box cupling 5 passes through spiral shell
Stricture of vagina is connected on joint 4, and it is semicircular convex that position corresponding with centralizer 2 on sucker rod body 1 is provided with one section of cross section
Playing 7, centralizer 2 is by being fixed on sucker rod body 1 with coordinating of projection 7.The setting of centralizer 2, is conducive to more preferably
Realize righting function, cross section is semicircular protruding 7 can directly to be realized by Sheet Metal Forming Technology, without machining, has
Effect controls processing cost.
Described centralizer 2 is made up of two parts, and two parts mate with the outside of sucker rod body 1 after fastening.Centralizer 2 is adopted
Using dismountable split-type design, both can install when producing, can install when construction again, property easy to use is increased
By force.Two parts of centralizer 2 are connected by screw 8, during construction, just can be with Fast Installation by electric screw driver, and during installation
Between short, working performance is high.Junction realizes location by the cooperation of positioning cylinder 9 and hole, location, it is ensured that install the standard of location
Really property and the concordance of processing quality.Described centralizer 2 is made up of nylon material, and nylon material is easily worked and manufacturing cost,
And there is good wearability.The outside of described centralizer is provided with scrapes wax pan 6, for striking off the solid wax of tube inner wall,
Prevent because wax deposition affected the latus rectum of liquid passage.
This utility model centralizer 2 is fixing with sucker rod to be connected, and righting is effective；Production difficulty of the present utility model is little, produces
Low cost, has preferable economic worth.
