Description
Technical field
The utility model relates to the maintenance technology fields of wellhead equipment, are specifically related to a kind of oil-extractor polish-rod downlink dedusting
Device.
Background technique
Carrying out maintenance to oil-extractor polish-rod is the operation that oil extraction operation personnel often carry out, especially for belching well and height
Corrode well, being easily worn there are packing leads to the situation that well head leaks and polished rod surface is easily damaged by corrosion, and maintains polished rod most
Effective mode is exactly that application maintenance box adds lubricating oil that the surface of polished rod is made to form stable oil film.
Although also having certain dustproof function based on the maintaining case that this purpose designs and manufactures, effect is not enough managed
Think, because maintaining case used at present is substantially to have by being bolted to be fastened on the surface of polished rod to polished rod surface
The purpose of effective dedusting is just not achieved if dynamics is inadequate in certain active force, and if dynamics is excessive to will increase pumping unit
Load, or even destroy polished rod surface oil film usually use corrosion inhibiter at present especially for high corrosion well and protected
It supports, if dynamics is excessive, there is also wasting, production cost can be increased to a certain extent.
Utility model content
The purpose of this utility model is in view of the above technical defects, to provide a kind of oil-extractor polish-rod downlink dust-extraction unit, is led to
It crosses and polished rod uplink and downlink is applied with different active forces respectively, while effectively being maintained, reach the mesh of effective dedusting
's.
Technical solution: a kind of oil-extractor polish-rod downlink dust-extraction unit, it includes the periphery that a pair of of mirror image is fastened on packing box
Side and by bolted fixation clamp, wherein the outer periphery of each fixation clamp is fixedly installed supporting plate, the supporting plate it is upper
Positioning plate is fixedly installed in the top of the longitudinally disposed strut in portion, the strut, on positioning plate setting axis, the axis
Be slidingly connected elbow crank, and the head of the elbow crank connects a semicircle scraping ring by connecting rod；The positioning plate it is upper
Connecting plate is fixedly installed in portion, and tension spring is arranged between the connecting plate and the semicircle scraping ring.
The inner wall of the positioning plate is transversely arranged latch, the latch in polished rod downlink with the elbow crank
Tail portion joining, to prevent the elbow crank from rotating.
The outer periphery of the semicircle scraping ring and the side of the connecting plate are respectively provided with the hanger for being provided with longitudinal hole, are used for
Hang the tension spring.
The utility model has the advantages that the utility model can apply different active forces to uplink polished rod and downlink polished rod, to polished rod
Achieve the purpose that be dusted it while effectively maintenance, and the utility model structure is simple, easy to manufacture and installation.
Detailed description of the invention
Attached drawing 1 is the schematic view of facade structure of the utility model；
Attached drawing 2 is the planar structure schematic diagram of the utility model.
Specific embodiment
Referring to attached drawing 1 and attached drawing 2, it includes that a pair of of mirror image is fastened on the outer periphery of packing box 2 and by bolted solid
Determine clamp, wherein supporting plate 13 is fixedly installed in the outer periphery of each fixation clamp 1, and the top of the supporting plate 13 is longitudinally disposed
Positioning plate 4 is fixedly installed in the top of strut 12, the strut 12, passes through the positioning plate 4 and axis 10 is arranged, live on the axis 10
Dynamic to be arranged elbow crank 9, the head of the elbow crank 9 connects a semicircle scraping ring 5 by connecting rod 8；The positioning plate 4
Connecting plate 7 is fixedly installed in top, and tension spring 6 is arranged between the connecting plate 7 and the semicircle scraping ring 5, the positioning plate 4
Inner wall is transversely arranged latch 11, the latch 11 in 3 downlink of polished rod with the tail portion joining of the elbow crank 9, with
Prevent the elbow crank 9 from rotating, the outer periphery of the semicircle scraping ring 5 and the side of the connecting plate 7 be respectively provided be provided with it is vertical
To the hanger 14 of through-hole, for hanging the tension spring 6.
The utility model is effectively to be protected by applying different active forces to uplink polished rod and downlink polished rod to polished rod
It supports and effective dedusting, due to the effect of tension spring 6, reduces the appearance of semicircle scraping ring 5 and polished rod 3 during 3 uplink of polished rod
The pressing force in face, so that semicircle scraping ring 5 can not destroy the oil film on 3 surface of polished rod, and during 3 downlink of polished rod, it is semicircle
Scraping ring 5 gradually increases the pressing force of polished rod 3, tension spring 6 can not fully against semicircle scraping ring 5 to the pressing force of polished rod 3, until
The tail portion of elbow crank 9 touches latch 11, and the pressing force gradually increased is overcome, and such polished rod 3 is in downlink mistake later
Cheng Zhong, semicircle scraping ring 5 will to polished rod 3 apply one it is relative constant and be greater than 3 uplink of polished rod when pressing force, thus may be used
Effectively to strike off the dust on the surface of polished rod 3, to reduce the abrasion between the sealed packing of the inside of polished rod 3 and packing box 2.
