Description
Technical field
The utility model relates to a kind of oil pumper, particularly one list column direct-drive type energy-saving pumping unit.
Background technology
There is two large problems in the oil pumper used at present, problem one is counterweight problem, particularly oily girder-like oil pump counterweight can not keep balancing with load constantly, so average load is only 30% of peak load, but select motor can only select by peak load, so belong to low load with strong power, cause the significant wastage of the energy; Problem two is commutation problems, what sucker rod rise and fall were done is move back and forth, and therefore vertical oil-pumping machine is all utilize motor positive and inverse to realize commutation, heavy-duty motor frequent starting, and commutation also needs brake when stopping, and therefore also result in the significant wastage of the energy.
Summary of the invention
The purpose of this utility model is to provide a kind of single column direct-drive type energy-saving pumping unit.
The utility model is made up of single column derrick, direct-drive type elevating mechanism, transmission mechanism and halyard, direct-drive type elevating mechanism is arranged on single column derrick, transmission mechanism is made up of the first fixed pulley and the second fixed pulley, first fixed pulley and the second fixed pulley are separately positioned on the top of single column derrick, halyard walks around the first fixed pulley and the second fixed pulley, one end of halyard connects with sucker rod, and the other end of halyard connects with the tooth bar seat upper end of elevating mechanism.
Described direct-drive type elevating mechanism is by tooth bar seat, annular rack, slide, motor, reductor, slide teeth roller box, Bevel Gear Transmission is secondary, travelling gear is formed, tooth bar seat is attached on slide and can slides up and down along slide, annular rack is arranged on tooth bar seat centre position, travelling gear engages with annular rack, travelling gear connects with the output shaft of Bevel Gear Transmission pair, Bevel Gear Transmission pair is arranged in slide teeth roller box, slide teeth roller box slides on base with dovetail type slideway mechanism, the power shaft of Bevel Gear Transmission pair has external splines, speed reducer output shaft has internal spline, power shaft can move in the output shaft of reductor.
The course of work of direct-drive type elevating mechanism is:
Driven by motor reductor, reductor drives the power shaft with external splines to rotate, and power shaft drives Bevel Gear Transmission subtask, and Bevel Gear Transmission subband nutating gear rotates, and drive gears moves annular rack and alternately moves up and down.Annular rack and then band carry-over bar seat up-down alternative motion, when travelling gear is positioned at the upper and lower sides of annular rack, Bevel Gear Transmission pair is slided with dovetail type slideway mechanism together with slide teeth roller box on base, and now, the power shaft with external splines moves in the output shaft of reductor.
The course of work of the present utility model: direct-drive type elevating mechanism drives its tooth bar seat to move up and down, and then drive sucker rod to move up and down by halyard, complete pumping operation.
The beneficial effects of the utility model:
1, the utility model is the commutation object realizing promoting sucker rod and decline sucker rod by direct-drive type elevating mechanism, and drive motors is without the need to driving commutation, and machine operation load is steady, and then saves electric energy, reduces cost of production and is conducive to environmental protection.
2, use single column derrick, structure is simple, easy for installation, reduces manufacturing cost.
3, the utility model transmits power by gear and pulley, and transmission efficiency is high.
