Pylon 3 is a split modular structure, is formed by connecting by at least two pylon splits, and be two among the figure, also can be elected to be three, four, five or six or the like as required.

Operating principle:

At first, starting torque required for the present invention is little.Required starting torque size during startup also is the required consumed power size of decision.The oil pumper motion process starts for the upstroke bottom dead centre, and------the upstroke top dead-centre slows down, and---the down stroke top dead-centre quickens---middle uniform motion---down stroke bottom dead centre and slows down middle uniform motion.We give long acceleration time can for last bottom dead centre.

When upstroke started, the frequency of PLC control circuit changed in time and at the uniform velocity strengthens, and rotating speed of motor is also accelerated with power frequency, and the quilt of this moment is dragged primer and also quickened even.Power frequency is just to reach the required stabilized frequency of oil pumper through after a while, and this section period is also dragged the even accelerating sections of primer.This moment is single from the motor aspect, has eliminated part and has been dragged the required energy consumption of primer momentum conversion.If allow motor locate at the uniform velocity under the state always, also will allow dragged the required power of primer momentum change will be very big:

F-Mg=MV/t

M weight quality

V weight speed

The F weight acts on power on the lifting rope

G acceleration of gravity

Required time when t reaches a constant speed

Must electric current can be very big, the motor in-fighting must increase.Must extend the acceleration time in order to reduce this in-fighting.In a segment distance of before top dead center, must slow down; Otherwise, when upper dead center position, can not stop oil pumper and drag primer and move upward; This moment electric current frequency step-down gradually, motor movement is negative acceleration.The motor institute work of this moment is:

E=Mgh-1/2MV 2

M weight quality

V weight uniform motion is a speed

G acceleration of gravity

H drags the primer move distance when being zero Zi the speed of reducing speed now

If want to allow motor acting this moment be zero to have only to motor and cut off the power supply.But outage can make the moving situation of oil pumper estimate.During down stroke, counterweight part is heavy behind the oil pumper.Oil pumper is the weight difference of back counterweight and the front end carried.That is to say that motor is in the action that repeats the oil pumper upstroke.Its required electric current reduces, so it is energy-conservation on the one hand for this.

Another causes the little reason of starting torque to be: cylinder 21 twines suspender belts realizes that cylinders 21 are (as the reducing of Fig. 5-Fig. 8).During upstroke, twining on the weighting distribution wheel has expired suspender belt, and the lifting wheel suspender belt is all emitted; Cause the wheel footpath of this moment not waited, back counterweight is big to the arm of force of bottom main shaft effect, and the arm of force of front end is less.Front and back to the moment that main shaft produces are:

M After=m AfterG (r+n AfterD)

M Before=m BeforeGr

M AfterThe moment that back counterweight produces on main shaft

M BeforeThe moment that back counterweight produces on main shaft

m AfterBack weight mass

m BeforeDrag the primer quality

R main shaft radius

n AfterSuspender belt twines the number of plies

D suspender belt thickness

Then the moment that this moment, the back counterweight produced at this moment is maximum, has reduced the moment of torsion that reducer will be exported, and has reduced the required electric weight of motor.The arm of force of counterweight is reducing after when polished rod load rises, and the front end arm of force is increasing; Simultaneously, also (crude oil flows out polished rod load gradually in the oil pipe reducing; Moreover in a segment distance that arrives top dead-centre, automatically controlled part requires polished rod load to do retarded motion).Front end arm of force maximum during to top dead-centre, rear end arm of force minimum.Repeated the operating mode of top dead-centre conversely.It has all reduced the required electric current of motor last bottom dead centre, so it is energy-conservation.

During work, cylinder 21 rolls, and drives the oil pumper motion.The commutation of oil pumper is that the conversion by electric current reaches.When the needs oil pumper was stepped down, lifting rope 9 broke away from from polished rod eye assembly 10 before allowing, the crawl oil pumper, and suspender belt 9 is embraced the pulley 48 on the semi girder 8 before making, and is slowly up, makes it to reach the requirement of oil pumper job position.

Embodiment two: present embodiment and embodiment one are basic identical, and something in common does not repeat, and difference is: pylon is a monolithic construction, without dismounting, simplifies construction sequence, is applicable to low pylon occasion.

Change power assembly concrete structure, change lubricated box concrete structure, change the concrete structure of cylinder, and the concrete structure that changes movable pulley mechanism can form a plurality of embodiment, is common variation of the present invention, do not describe in detail one by one at this.
