The sucker rod drive device has the beneficial effects that the reactive loss is greatly reduced through the permanent magnet synchronous motor to ensure that the energy saving effect of the sucker rod drive device can reach about 80 percent; and meanwhile, through the double-output shaft characteristic of the drive motor, the transmission shaft is driven by the two transmission belts to rotate, and thus the bearing capacity and the transmission efficiency are increased to ensure that the transmission belts can easily drive the transmission shaft to rotate, and the service life of the transmission belts can be prolonged.
Description
Technical field
The utility model relates to, especially a kind of oil pumper.
Background technology
Oil pumper is a kind of machinery equipment of recover petroleum, is commonly called as " machine of kowtowing ", makes oil go out well by the way of pressurizeing.The normally used oil pumper of oil exploitation is a beam pumping unit at present, and beam pumping unit mainly is made up of walking beam, connecting rod, crank mechanism, reduction box, power-equipment and auxiliary equipment etc.The oil pumper of this kind structure is to realize the driven by motor sucker rod in in-oil cylinder reciprocating motion by cooperatively interacting of belt deceleration, gear and linkage, makes beam pumping unit have the defective that overall volume is big, floor space is big, machinery driving efficiency is low, stroke is short and tar productivity is low like this.Therefore, in order to address the above problem, a kind of tower-type pumping unit has now appearred on the market, it mainly comprises the upright pylon that is located on the ground, be fixed on the drive unit of tower top, walk around the lifting rope of drive unit output, and the sucker rod that is fixed on lifting rope one end is formed with the parts such as balance weight body that are fixed on the lifting rope other end, wherein, drive unit comprises drive motors, driving gear, driving-belt, power transmission shaft, travelling gear and traction sheave, this driving gear is fixed on the output shaft of this drive motors, this travelling gear is fixed in outside the axial end of this power transmission shaft, this travelling gear and this driving gear are in transmission connection by this driving-belt, and this traction sheave cover is fixed on outside the axial other end of this power transmission shaft, and it is little that this kind tower-type pumping unit has overall volume, floor space is little, the machinery driving efficiency height, the advantage that stroke is long and tar productivity is high.
Yet the drive unit of this kind tower-type pumping unit, its drive motors are asynchronous machine, and the inactivity of asynchronous machine can reach 20%, and power utilization is low, wastes energy; And this drive motors is single output shaft motor, and bearing capacity is little, and transmission efficiency is low, and the weight of sucker rod is heavier, make driving-belt can drive the rotation of power transmission shaft like this, driving-belt is easy to wear when using for a long time, has shortened the useful life of driving-belt greatly comparatively painstakingly.
In view of this, the inventor furthers investigate the above-mentioned defective of oil pumper drive unit, then produces in this case.
The utility model content
It is big that the purpose of this utility model provides a kind of bearing capacity, and the transmission efficiency height can prolong the beam hanger drive unit of the oil pumper in driving-belt useful life.
The technical solution of the utility model is such: a kind of beam hanger drive unit of oil pumper, comprise drive motors, driving gear, driving-belt, power transmission shaft, travelling gear and traction sheave, this driving gear is fixed on the output shaft of this drive motors, this travelling gear is fixed in outside the axial end of this power transmission shaft, and this travelling gear and this driving gear are in the same side, this travelling gear and this driving gear are in transmission connection by this driving-belt, and this traction sheave cover is fixed outside the axial other end of this power transmission shaft; Above-mentioned drive motors is a permagnetic synchronous motor, and above-mentioned permagnetic synchronous motor is the double output shaft permagnetic synchronous motor, above-mentioned driving gear, above-mentioned driving-belt and above-mentioned travelling gear all with the corresponding setting of the output shaft of above-mentioned drive motors.
Above-mentioned traction sheave is provided with two, and two above-mentioned traction sheaves are coaxial to be provided with side by side at interval.
After adopting such scheme, the beam hanger drive unit of a kind of oil pumper of the present utility model, because drive motors is the double output shaft permagnetic synchronous motor, and the reactive loss of permagnetic synchronous motor approaches zero, greatly reduce the reactive loss of drive unit like this, make the energy-saving effect can be, avoided inactivity because of the conventional asynchronous motor to reach 20% problem that causes energy waste up to about 80%; Simultaneously the double output shaft characteristic by drive motors and driving gear, driving-belt and travelling gear all with the corresponding setting of the output shaft of drive motors, make the rotation of power transmission shaft bring drive like this by two transmissions, bearing capacity and transmission efficiency have been improved, strengthened the transmission torsion of power transmission shaft, make driving-belt can drive the rotation of power transmission shaft like a cork, thereby can prolong the useful life of driving-belt; Because traction sheave is provided with two, the oscilaltion that drives sucker rod by two traction sheaves is moved like this, can make the oscilaltion of sucker rod move comparatively steady again.
