Description
Technical field
The present invention relates to technical field of mechanical oil extraction, specifically, belong to a kind of novel rod-type righting wax scraping apparatus.
Background technology
Crude oil in China wax is more, wax deposition phenomenon often occurs inside oil pipe so that the reduction of overflowing end face, pit shaft in oil pipe
Narrow, oil well output reduces, and oil pipe can be also blocked when serious, oil well is caused to stop production.Wax scraping apparatus is installed on sucker rod to oil pipe
It is one of most common wax removal mode in oil field that the wax of inner wall, which carries out cleaning, existing patent plugging sucker rod centering paraffin scraper and new
Type sucker rod stabilizing wax scraping apparatus is installed on sucker rod by inserting mode.However above-mentioned patent is in grafting, due to
Its inserting mode makes axial lock clamp force often not reach requirement, and it is difficult to be fixed to some on sucker rod to lead to righting wax scraping apparatus
Position is easy to happen play and falls off, and the effect is unsatisfactory for paraffin cutting, and wax scraping apparatus is easy to channel at rod collar,
Its righting effect is set to substantially reduce.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide can solve righting wax scraping apparatus axial lock clamp force
A kind of undesirable novel rod-type righting wax scraping apparatus with the problem of righting effect difference of paraffin cutting effect caused by deficiency.
To achieve the goals above, the present invention adopts the following technical scheme that：It is by upper half ring cylinder, upward arrow type righting
Block, lower half ring cylinder, under arrowhead-shaped wiper block composition；Wherein upper half ring cylinder includes that locking ratchet and guide rail, upward arrow type are helped
Positive block includes non-return ratchet and is provided with guide-track groove, and lower half ring cylinder includes locking ratchet and guide rail, under arrowhead-shaped wiper block include
Non-return ratchet is simultaneously provided with guide-track groove；It casts and is integrated between upper half ring cylinder and upward arrow type wiper block, lower half ring cylinder is under
Casting is integrated between arrowhead-shaped wiper block, and upward arrow type wiper block arrowhead-shaped righting block structure under is identical, the two phase
It is arranged to standing upside down；Upper half ring cylinder under arrowhead-shaped wiper block by lock ratchet and non-return ratchet mutual ratcheting connection, under
It is also the mutual ratcheting connection by locking ratchet and non-return ratchet between half ring cylinder and upward arrow type wiper block.
Guide rail has 1 in the axial direction:30~1:Gradient in 60 ranges.
Compared with the prior art the present invention has the following advantages：
1）The configuration of the present invention is simple, rod-type righting wax scraping apparatus is by high-strength abrasion-proof nylon material injection molding, wear-resistant, weight
Gently, it makes at low cost.
2）The present invention is easy for installation, by locking ratchet and the mutually ratcheting connection of non-return ratchet, prevents it from axial alter occurs
It is dynamic, it can firmly be fixed on sucker rod.
3）The present invention can pump with sucker rod, and energy 360 ° omni-directional removes the wax on tube inner wall, reduces
The oil well operation period.
Description of the drawings：Fig. 1 is the overall structure schematic diagram of the present invention；Fig. 2 is lower half ring cylinder arrowhead-shaped wiper block under
Side view；Fig. 3 is the rearview of lower half ring cylinder arrowhead-shaped wiper block under；Fig. 4 is the present invention and main view before sucker rod assembly
Figure.
In figure：1. arrowhead-shaped wiper block, 5. locks under upper half ring cylinder, 2. upward arrow type wiper blocks, 3. lower half ring cylinders, 4.
Tight ratchet, 6. guide rails, 7. non-return ratchets, 8. guide-track grooves, 9. sucker rods.
Specific implementation mode：Below in conjunction with attached drawing, the invention will be further described, it is by upper half ring cylinder 1, upward arrow
Type wiper block 2, lower half ring cylinder 3, under arrowhead-shaped wiper block 4 form；Wherein upper half ring cylinder 1 includes locking ratchet 5 and guide rail
6, upward arrow type wiper block 2 includes non-return ratchet 7 and is provided with guide-track groove 8, and lower half ring cylinder 3 includes locking ratchet 5 and guide rail 6,
Under arrowhead-shaped wiper block 4 include non-return ratchet 7 and being provided with guide-track groove 8；It is cast between upper half ring cylinder 1 and upward arrow type wiper block 2
Make and be integrated, lower half ring cylinder 3 and under cast between arrowhead-shaped wiper block 4 and be integrated, upward arrow type wiper block 1 is arrowhead-shaped under
4 structure of wiper block is identical, the opposite arrangement of standing upside down of the two；The arrowhead-shaped wiper block 3 under of upper half ring cylinder 2 passes through locking ratchet
5 and non-return ratchet 7 mutual ratcheting connection, between lower half ring cylinder 3 and upward arrow type wiper block 2 be also by lock ratchet 5
With the mutual ratcheting connection of non-return ratchet 7.
Guide rail 6 has 1 in the axial direction:30~1:Gradient in 60 ranges.Insertion depth with guide rail 6 in track groove 8 increases
Add, axial lock clamp force will increase, and in the case where locking ratchet 5 and non-return ratchet 7 are mutually ratcheting, it is ensured that wax scraping apparatus can be firmly
Be fixed on sucker rod 9, will not occur axial float and to fall off.
It when onsite application, is needed at righting position in sucker rod 9, first by upper half ring cylinder 1 together with upward arrow type righting
Block 2 is installed from the top of sucker rod 9, and then by lower half ring cylinder 3, arrowhead-shaped wiper block 4 is pacified from the lower part of sucker rod 9 together under
Dress, it is ensured that the guide rail 6 of upper half ring cylinder 1 and lower half ring cylinder 2 is inserted into guide-track groove 8, while ensureing to lock ratchet 5 and non-return spine
It is completely ratcheting between tooth 7.In addition, guide rail 6 has 1 in the axial direction:30~1:Gradient in 60 ranges, as guide rail 6 is in track groove
8 insertion depth increases, and axial lock clamp force will increase, and mutual ratcheting between locking ratchet 5 and non-return ratchet 7
Under, it is ensured that wax scraping apparatus can be firmly fixed on sucker rod 9, and play will not occur and fall off.
Upward arrow type wiper block 2 after installation is complete and under be flow channel between arrowhead-shaped wiper block 4, upward arrow type is helped
Positive block 2 and under circumferentially-spaced 180 ° between arrowhead-shaped wiper block 4, can be contacted with oil pipe 360 ° omni-directional, it is reciprocal in sucker rod 9
In motion process, the wax deposition in 360 ° of circumferential directions of tube inner wall can be struck off, and have the function of good righting.
