Abstract
The utility model relates to an eccentric self regulation paraffin scraping for wellhead rod in the technology field of well workover in oil development, comprising a main body 1, a coil cable 2, a tooth block 4, a sleeve gasket 9, a mobile board 10 and a fixed board sleeve 11, etc. The coil cable 2 is arranged on the main body 1 and a tooth block seat 3 in the main body 1; the tooth block 4 is fixed by a fixed bolt 5 and the sleeve gasket 9 and the mobile board 10 are connected through a bolt 7 and a spring washer 8; the fixed board sleeve 11 is positioned on the central hole of the sleeve gasket 9 and the mobile board 10. Therefore, no external force is needed, the paraffin scraping can be carried out automatically; no manual operation is needed, the utility model can be positioned at the wellhead to automatically carry out paraffin scraping, thereby improving working efficiency and guaranteeing production safety.
Description
Relate to the field
The utility model belongs to oil development well workover technology field, is a kind of novel paraffin cutting instrument that is used for sucker rod paraffin scraping, specifically, is eccentric self-adjustable well head sucker rod paraffin scraping device.
Background technology
At present, domestic most of oil field is when well workover, basically all adopt wire rope or V-belt to be wrapped on the sucker rod to the sucker rod paraffin scraping that trips out, draw steel wire or belt by the people, on carry beam hanger and realize paraffin cutting, and oil pumping rod centering device can't be by steel wire or the belt that twines, and the method operation effort is dangerous again.
Technology contents
The purpose of this utility model is to provide a kind of workman's of need not manual operations, is installed on the well head and can implements paraffin cutting automatically, increases work efficiency, guarantees the eccentric self-adjustable well head sucker rod paraffin scraping device of production safety.
The utility model is achieved in that
Comprise that main body 1, ring spring 2, block teeth sit 3, block teeth 4, fixed screw 5, pin 6, bolt 7, spring washer 8, spacer 9, portable plate 10, fixing sleeve-board 11, ring spring 2 is arranged on the main body 1, tooth block seat 3 is arranged in the main body 1, block teeth 4 are fixing with set bolt 5, spacer 9, portable plate 10 connect by bolt 7, and fixedly sleeve-board 11 places on the pore location of spacer 9, portable plate 10.
The utility model also adopts following technical scheme:
Block teeth 4 can be more than one.
Spring washer 8 is arranged between bolt 7 and the connector.
There is pin 6 end on block teeth 4 inclined-planes.
Advantage of the present utility model is: do not need additionaling power, can implement paraffin cutting automatically, need not workman's manual operations, be installed on the well head and can implement paraffin cutting automatically, increase work efficiency, guaranteed production safety.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Concrete enforcement
As shown in the figure, the utility model mainly by main body 1, ring spring 2, block teeth sit 3, block teeth 4, fixed screw 5, pin 6, bolt 7, spring washer 8, spacer 9, portable plate 10, fixedly sleeve-board 11 etc. is formed, ring spring 2 is arranged on the main body 1, tooth block seat 3 is arranged in the main body 1, block teeth 4 are fixing with set bolt 5, spacer 9, portable plate 10 connect by bolt 7, spring washer 8, and fixedly sleeve-board 11 places on the pore location of spacer 9, portable plate 10.
Last when carrying sucker rod, main body 1 part is along with the swing of sucker rod any direction or rotate, and guarantees that two pairs of block teeth 4 are aimed at all the time with sucker rod up and down, and block teeth 4 are held sucker rod tightly, and along with the lifting of sucker rod, wax and part that block teeth 4 are wiped off on the sucker rod are dirty.When running into rod collar, centralizer, shadoof post in the continuation, make its box cupling, centralizer up along block teeth 4 inclined-planes, block teeth 4 outwards overturn, and it passes through smoothly, works as box cupling, hold up the shake device by behind the block teeth 4 up and down, block teeth 4 reset under the effect of ring spring 2 spring forces, still hold sucker rod paraffin scraping tightly, and the wax that scrapes can unload wax pan by main body 1 and discharge.
