The long-stroke energy-saving oil extractor that the utility model provides is characterized in that comprising base (1), small footprint (2) frame (3), polished rod (4), preceding support (5), polished rod eye (6), pull rope (7), directive wheel support (8), directive wheel axle bed (9), directive wheel (10), reducer (11), driving wheel (12), upper mounting plate (13), ladder (14), (15) are supported in the back, counterweight slide rail (16), counterweight pull rope (17), counterweight polished rod eye (18), main ballast box (19), pulley (20), secondary ballast box (21), cushion pad (22), switch board (23), guardrail (24), two-layer platform (25), motor (26), live axle bearing (27), output shaft shaft coupling (28), input shaft coupling (29) decelostat (30) turnover bracket (31); Described reducer (11) links to each other with motor (26) by power shaft shaft coupling (29), decelostat (30), and reducer (11) output shaft links to each other with driving wheel (12) by shaft coupling (28); Described balance weight body is made up of main ballast box (19), secondary ballast box (21), pulley (20), and heavy metal powder is equipped with in wherein main ballast box and secondary ballast box inside; Described pull rope (7) one ends are connected with polished rod (4), and an end is connected by the inner fixed axis of directive wheel (10) and driving wheel (12), and described counterweight pull rope (17) one ends are connected with the fixed axis of driving wheel inside, and the other end is connected with counterweight polished rod eye (18).
In the long-stroke energy-saving oil extractor that provides according to the utility model, be provided with hard flank of tooth reducer, moment of torsion is big, reliability is high, efficient is high, make oil pumper have shock resistance, overload-resistant ability improves greatly, reducer input, output shaft at the same side motor at the main frame center, topology layout is reasonable, operates steadily, thus the application life of having improved complete machine.Described motor is a switched reluctance machines, has the advantages that starting current is little, moment of torsion big, be fit to frequent rotating operating mode.Described balance weight body is made up of main ballast box and secondary ballast box, and heavy metal powder is equipped with in inside, can accurately adjust counterweight.
Controller can control that motor softly stops, soft opening, and reduces that commutation suddenly starts and the shock loading that causes, thus the life-span of having improved transmission system greatly.
Guiding wheel carrier (7) can hypsokinesis 50 °～60 °, can get out of the way well head easily during workover treatment.
This oil pumper has upper mounting plate balance of plant layout in sum, rational in infrastructure, advantages such as adjustment is easy, easy to maintenance, reliable, pumping efficiency is high, the operation noise is low, environmental protection and energy saving.Compare with conventional beam-pumping unit and can economize on electricity 30～50%, pump efficiency improves more than 20%.This long-stroke energy-saving oil extractor can be widely used in various types of oil fields.

The specific embodiment
The utility model is described in further detail in conjunction with the accompanying drawings with specific embodiments for the utility model, but protection domain of the present utility model is not limited to following specific embodiments.
The long-stroke energy-saving oil extractor that the utility model provides comprises: go up at top platform (13) motor (26), decelostat (30), reducer (11), reducer input and output shaft shaft coupling (29), (28), driving wheel (12) are installed.During work, the operation of switch board (23) control motor (26) forward and backward, drive driving wheel (12) by reducer input shaft shaft coupling (29), reducer (11), reducer output shaft coupling (28) and do the forward and backward operation, pull rope (7) one ends are connected with polished rod (4), one end is connected by the inner fixed axis of directive wheel (10) and driving wheel (12), when driving wheel (12) was done the forward and backward operation, pull rope (7) drove polished rod (4) lifting by polished rod eye (6) or descends.Pull rope (7) one ends are connected with polished rod, one end is connected by the fixed axis of directive wheel with driving wheel inside, described counterweight pull rope (17) one ends are connected with the fixed axis of driving wheel inside, and the other end is connected with ballast box (19), (21) by counterweight polished rod eye (18).When driving wheel (12) when making positive and negative rotating operation, drive pull rope (7) polished rod eye (6) polished rod (4) and do straight reciprocating motion with counterweight pull rope (17), counterweight polished rod eye (18), ballast box (19), (21).Polished rod load and ballast box load accurate balance, motor (26) rotating commutation running drives driving wheel, wire rope, directive wheel by reducer input, output shaft coupling, makes sucker rod and deep well pump do straight reciprocating motion, finishes the crude oil swabbing operation.
