Description
Technical field
The utility model relates to the oil pumper field, particularly a kind of gear drive formula autobalance beam-pumping unit.
Background technology
Conventional beam-pumping unit mainly is made up of four major parts such as walking beam-connecting rod-crank mechanism, reduction box, power-equipment and auxiliary equipment at present.During work, the transmission of motor becomes moving up and down of horse head through gearbox, crank-link mechanism, horse head moves up and down through the plunger that polished rod, sucker rod drive the down-hole deep well pump, thereby constantly the crude oil in the well is extracted out pit shaft, be characterized in: said device features rational structure, stable working, little, the convenient operating maintenance of noise.
Beam pumping unit is a kind of quadric chain of distortion, and its complete machine structure characteristics are as a balance, and an end is an oil pumping load, and the other end is a counterweight load.For support,, with very little power oil pumper is worked uninterruptedly so if the moment of torsion of oil pumping load and balancing load formation equates or variation is consistent.
Beam balance structure commonly used is that this is a kind of simple balance mode, is applicable to the light-duty oil pumper below 3 tons at the balance plate of the afterbody installing constant weight of walking beam.When the sucker rod load increase appears blocking in pit shaft, need to shut down and install balance plate additional at the walking beam afterbody; And after dredging a well, sucker rod load is light, needs to remove balance plate again, sets up new balance, and labour intensity is big, and precision is low.
Summary of the invention
The purpose of this utility model provides a kind of gear drive formula autobalance beam-pumping unit, overcomes the deficiencies in the prior art, drives walking beam with the gear drive connecting rod, and the walking beam counterweight can be adjusted under not shutdown situation continuously, improves and adjusts efficient and precision.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Gear drive formula autobalance beam-pumping unit, comprise reductor, walking beam, horse head, connecting rod, horse head is arranged on an end of walking beam, the walking beam other end is provided with counter weight device, walking beam stage casing and overturning seat are hinged, it is characterized in that, speed reducer output shaft is provided with driven wheel, driven wheel is meshed with travelling gear, connecting rod one end is arranged on the lateral margin of travelling gear, the connecting rod other end is connected with the walking beam afterbody, and described counter weight device and walking beam afterbody are hinged, and counter weight device one end is connected by electric pushrod with walking beam.
Described driven wheel is provided with in pairs, is located at the speed reducer output shaft two ends respectively.
Described travelling gear also is provided with in pairs, is located at the two ends of power transmission shaft respectively, is provided with bearing support between power transmission shaft and the support.
Compared with prior art, the beneficial effects of the utility model are: 1) bidentate wheel driven in synchronism, transmission accuracy height, energy and labour saving; 2) can realize the continuous adjustment of walking beam counterweight under not shutdown situation by the mode of control electric pushrod adjusting counterbalance moment, improve and adjust efficient and precision.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, it is the utility model gear drive formula autobalance beam-pumping unit structural representation, comprise reductor 1, walking beam 12, horse head 14, connecting rod 8, horse head 14 is arranged on an end of walking beam 12, walking beam 12 other ends are provided with counter weight device 13, walking beam 12 stage casings and overturning seat 10 are hinged, motor 3 is by belt 2 drive speed reducer 1, be provided with driven wheel 5 on the speed reducer output shaft 4 in pairs, driven wheel 5 correspondences are meshed with a travelling gear 6, connecting rod 8 one ends are arranged on the lateral margin of travelling gear 6, connecting rod 8 other ends are connected with walking beam 12 afterbodys, described counter weight device 13 is hinged with walking beam 12 afterbodys, and counter weight device 13 1 ends are connected by electric pushrod 11 with walking beam 12.Safety guard 9 covers reductor 1 and travelling gear 6, with preventing wetting.
A pair of travelling gear 6 is separately positioned on the two ends of power transmission shaft 16, is provided with bearing support 17 between power transmission shaft 16 and the support 7.Two connecting rods 8 affect horse head 14 respectively by travelling gear 6 drives swing synchronously separately, and sucker rod 15 is moved up and down.
When sucker rod 15 load increases appear blocking in pit shaft; only need electric pushrod 11 to be shunk a bit by control device; counter weight device 13 is promptly protruding; counterbalance moment is increased; observe motor 3 electric currents, in current value is got back to rated range, adjust and finish; this device can make counterweight adjust the precision raising, needn't shut down.Otherwise after dredging a well, sucker rod load alleviates greatly, and electric pushrod 11 is stretched out, and shortens counterbalance moment, thereby saves the consumption of electric energy.
