Abstract
The utility model relates to an oil pumping pole wax scratching device of opposite opening type for scratching away the close wax, asphalt and rubber on the oil pumping pole. The utility model includes an opposite opening wax scratching tooth 3, a spring 6, and a dreg discharging hole7; wherein, a shell 8 is provided with the spring 6; the end of the spring 6 is provided with a spring baffle 2; a pressure regulating screw rod 4 is connected with the spring baffle 2; the middle part of the shell 8 is provided with the opposite was scratching tooth 3; the shell 8 is provided with the dreg discharging hole 7. The utility model chooses opposite wax scratching tooth with the related specification according to different types and waxing conditions of the oil pumping pole to regulate the pressing force on the oil pumping pole of the opposite was scratching tooth; with a lifting device of the well fixing work, base oil as well as close wax, asphalt and rubber is removed from the external wall of the oil pumping pole automatically and completely; at the same time, scratched base oil and rubber are discharged from the dreg discharging hole to reduce environment pollution.
Description
Technical field
The utility model relates to the thorough cleaning of sucker rod in the workover treatment, is specially adapted to scrape off on the sucker rod a kind of opposite opened rod scraper of glued more dense wax, asphalitine and colloid.
Background technology
The rod scraper of mining site, field use mainly partly is made up of rubber tube clamper and paraffin cutting rubber tube etc. at present.When workover treatment plays sucker rod, rod scraper is installed on production tree, make sucker rod pass rubber tube, on when carrying sucker rod, under the extruding force effect of rubber tube, wipe crude oil and cement on the sucker rod outer wall off, when rod collar arrives the paraffin cutting rubber tube, the rubber tube pressurized, rely on the elastic deformation of rubber, rod collar safety is passed through.But mining site is used and is shown, because the paraffin cutting rubber tube is unadjustable to the extruding force of sucker rod, cause the crude oil that can only scrape off the sucker rod outer wall and softer cement, can't scrape off its outer wall glued fine and close wax, asphalitine and colloid, the effect of the thorough wax removal of sucker rod in the time that workover treatment can't being reached.
Technology contents
The purpose of this utility model be to provide a kind of can be according to sucker rod wax deposition situation, timely adjustment opposite opened pumping rod wax scraping tooth is to the extruding force of sucker rod, by " hard paraffin cutting " the opposite opened rod scraper of the thorough wax removal effect of sucker rod when reaching workover treatment.
The utility model is achieved in that by adjusting nut 1, spring stop 2, splits paraffin cutting tooth 3, pressure adjusting screw 4, shelves cap 5, spring 6, lets out cinder hole 7, housing 8 is formed, there is grade cap 5 end of housing 8, on the shelves cap 5 adjusting nut 1 is arranged, spring 6 is arranged in the housing 8, there is spring stop 2 end of spring 6, pressure adjusting screw 4 is connected with spring stop 2, and paraffin cutting tooth 3 is split at the middle part of housing 8, lets out cinder hole 7 on the housing 8.
The utility model also adopts following technical scheme:
Split paraffin cutting tooth 3 between spring 6.
Spring 6 can be more than one.
Split paraffin cutting tooth 3 inside and be through hole, the part of through hole is circular, and another part is taper.
The opening diameter of splitting paraffin cutting tooth 3 is Φ 16, Φ 19, Φ 22, Φ 25.
On the shelves cap 5 centre bore is arranged.
Advantage of the present utility model is: can be according to the different model and the wax deposition situation of sucker rod, that selects corresponding specification splits the paraffin cutting tooth, squeeze the embrace power of paraffin cutting tooth to sucker rod is split in timely adjustment, rely on the hoisting mechanism of workover treatment, automatically and up hill and dale remove crude oil and glued fine and close wax, asphalitine and the colloid of sucker rod outer wall, simultaneously, can discharge crude oil that scrapes and cement by letting out the cinder hole orientation, to reduce environment pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structural representation of splitting paraffin cutting tooth 3.
Concrete enforcement
By adjusting nut 1, spring stop 2, split paraffin cutting tooth 3, pressure adjusting screw 4, shelves cap 5, spring 6, let out cinder hole 7, housing 8 is formed, during installation, can be respectively in the both wings of housing 8 equity pack into and split paraffin cutting tooth 3, spring 6, spring stop 2,1 interference of pressure adjusting nut is embedded in the centre bore of shelves cap 5, spiral shell entrance pressure power adjusting screw(rod) 4 again, then shelves cap 5 usefulness screw threads are connected as one with housing 8, like this, spring stop 2 and split paraffin cutting tooth 3 and certain clearance is arranged with housing 8 both wings, when splitting that paraffin cutting tooth 3 is subjected to expand and when regulating pressure adjusting screw 4, spring stop 2 and split paraffin cutting tooth 3 and can in the both wings of housing 8, move; Spring 6 two ends are recessed into spring stop 2 and split in the both ends of the surface groove of paraffin cutting tooth 3, can guarantee that each parts is stressed evenly.
