Abstract
A crank pin lining extractor comprises a lead screw (1), a fixing screw nut (2), a supporting cylinder (3), a pipe-jacking (4), a bearing (5), a power screw nut (6), and handles (7). The crank pin lining extractor is characterized in that the crank pin lining extractor supporting cylinder (3) is bucket-shaped, a center hole (A) is formed in the bottom portion of the supporting cylinder (3), the fixing screw nut (2) is installed at the right end of the lead screw (1), the lead screw (1) penetrates through the center hole (A), the pipe-jacking (4), the bearing (5) and the power screw nut (6) are sequentially installed at the right end of the lead screw (1), the bearing (5) is inlaid in the center of the power screw nut (6), and the two handles are symmetrically arranged on the power screw nut (6). The crank pin lining extractor is simple in structure, safe to operate, time-saving and labor-saving, short in downtime, improved in oil production rate, and capable of preventing sand blocking and failures of a well with a severe sand output, increasing crude output, and improving the economic benefits of an enterprise.
Description
Technical field
The utility model relates to the oil field beam pumping unit and changes crankpin bush aid, specifically a kind of crank pins bush extractor.
Background technology
Beam pumping unit is in service in long-term production, take off because crank pins is loosening, disconnected to cause various faults, even the major accident that causes oil pumper to turn over machine occurs.Find after deliberation, the crank pins lining is impaired, be cause that crank pins is loosening, disconnected taking off and cause oil pumper to turn over the main cause of machine accident.Because the crank pins lining is hidden in the crank hole inwall, in conjunction with very tight, damaged part is difficult the discovery, and Renewal process is wasted time and energy, and easily is left in the basket and is difficult for changing, and therefore, will cause and newly change crank pins and damage impaired once again because of lining; When therefore changing crank pins, the crank pins lining must be changed simultaneously, the potential safety hazard of crank pins could be thoroughly eradicated.Getting at present lining mainly is to be knocked with sledgehammer by turns by 4～5 people, some difficult especially lining of getting, also need to employ gas cutting and carry out the destructiveness dismounting, above taking-up mode not only wastes time and energy, and crank hole tended to cause certain damage, stopping the well overlong time affects crude output, also can cause the sand card well of lying for the serious well that shakes out.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of crank pins bush extractor.
The utility model is realized by following technical proposals:
The utility model comprises: leading screw, hold-down nut, support tube, push pipe, bearing, power nut, handle.Its crank-pin pin bush extractor support tube is the bucket shape, and the bottom is provided with centre bore, and the leading screw right-hand member is equipped with hold-down nut, leading screw passes from centre bore, the leading screw left end is equipped with push pipe, bearing, power nut successively, and bearing is set in the center of power nut, and the power nut is arranged with two handles.
Push pipe in the above-mentioned crank pins bush extractor is cylindrical shape, and left end is provided with the one-level ring-shaped step, and step withstands lining.
The beneficial effects of the utility model are: simple in structure, and handling safety, time saving and energy saving, downtime is short, rate when improve recovering the oil, the serious well of avoiding shaking out causes the sand card well of lying, and increases crude output, improves Business Economic Benefit.
