Abstract

A kind of balanced type tower shelf type oil pumping machine, it is characterized in that a driving platform is flexibly connected on upper mounting plate, motor, reduction box and driving wheel are all disposed within driving platform, a tune loaded van is set below driving platform, a follower is set on its wheel shaft, driving rope is fixed on the drive wheel, and drives the both ends of rope to be fixedly linked respectively with follower.The present invention adjusts the weight of loaded van by regulation, when making oil pumper normal operation, the nearly 1/2 oil column weight of differential of the driving force of driving wheel both sides driving rope, then the tractive force subtractive of the sucker rod pull rope in complete machine and ballast box pull rope is small, at this moment driving rope overcomes a part of frictional force and worked, therefore energy-saving effect is produced, oil pumper abrasion is reduced, extends oil pumper service life.

Description

Balanced type tower shelf type oil pumping machine
Technical field
The present invention relates to a kind of oil recovery machiner, more particularly, to a kind of energy-saving tower shelf type oil pumping machine.
Background technology
In the case of energy scarcity, electric power wretched insufficiency, energy-conservation turns into critically important subject under discussion.Oil pumper is that oil field is main Production equipment, for low-permeability oil field, oil level forms slow, and for a long time all in idle running, this will for most of oil pumper A large amount of electric energy are wasted, and cause oil pumper to wear, reduce the oil pumper life-span.
At present, conventional tower shelf type oil pumping machine is relative to conventional beam-pumping unit relative energy-saving, but energy-saving effect is also remote Far national energy-saving requirement is not reached.Its drive part of tower shelf type oil pumping machine is fixed on framework, is arrived when the weight of ballast box is set When rod weight adds 1/2 oil column weight, when no matter sucker rod rises or declined, sucker rod pull rope and ballast box traction The tractive force of rope differs 1/2 oil column weight all the time, therefore both sides can not balance all the time, and power consumption is big, with national energy-saving requirement apart It is very remote, oil pumper abrasion increase, reduce the oil pumper life-span.
The content of the invention
The problem of technical problems to be solved by the invention are big existing oil pumper power consumption, serious wear, low life-span, so as to A kind of balanced type tower shelf type oil pumping machine is provided.
In order to solve the above technical problems, the present invention provides a kind of balanced type tower shelf type oil pumping machine, mainly including base, frame Frame, ballast box, sucker rod, oil pick-up tube, electrical control cubicles, motor, reduction box, driving wheel, directive wheel, head sheave, framework are located at base On, upper mounting plate is provided with above framework, motor is connected successively with reduction box and driving wheel, it is characterised in that:On upper mounting plate Face is flexibly connected a driving platform, and motor, reduction box and driving wheel are all disposed within driving platform, are driven and are set one below platform Loaded van is adjusted, a follower is set on day wheel shaft, driving rope is fixed on the drive wheel, and drives the both ends of rope to consolidate respectively with follower It is fixed to be connected.
Drive platform that one hinge axis is installed below by two bearing blocks, the both ends of hinge axis are fixed on the axle on upper mounting plate On watt fixator.
Driving platform is connected to above upper mounting plate and one end away from driving wheel, adjusts loaded van to be arranged on position below driving platform In driving wheel one end.
The driving force difference of driving wheel both sides driving rope is 1/2 oil column weight.
The present invention adjusts the weight of loaded van by regulation, and when making oil pumper normal operation, driving platform around hinge axle rotates, and drives There is difference in the driving force of the driving rope on driving wheel both sides, then the tractive force of the sucker rod pull rope in complete machine and ballast box pull rope Poor corresponding reduction, at this moment drives rope to overcome a part of frictional force and work, therefore produces energy-saving effect, reduces oil pumper mill Damage, extend oil pumper service life.When driving force difference is 1/2 oil column weight, sucker rod pull rope and ballast box pull rope Tractive force is equal, reaches balance, and energy-saving effect is optimal.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention;
Fig. 2 is Fig. 1 left view.
In figure:Oil pick-up tube 1, sucker rod 2, base 3, framework 4, ballast box 5, polished rod eye 6, bearing shell fixator 7, hinge axis 8, Bearing block 9, driving platform 10, upper mounting plate 11, tune loaded van 12, motor 13, reduction gearbox output shaft 14, driving wheel 15, directive wheel Frame 16, sucker rod pull rope 17, guide wheel shaft 18, directive wheel 19, day wheel shaft 20, head sheave 21, day wheel support 22, driving rope 23, Ballast box pull rope 24, reduction box 25, electrical control cubicles 26, follower 27.
Embodiment
Reference picture 1, Fig. 2, the specific embodiment of the invention are the installation day wheel shafts on the upper mounting plate 11 at the top of framework 4 20, head sheave 21 and follower 27 are secured on day wheel shaft 20, while directive wheel 19 is installed with guide wheel bracket 16, sucker rod 2 is logical Cross polished rod eye 6 and be connected to sucker rod pull rope 17, sucker rod pull rope 17 is by fixed, ballast box on directive wheel 19 to head sheave 21 5 are connected with ballast box pull rope 24, and last ballast box pull rope 24 is fixed in head sheave, drive the motor 13 on platform 10 defeated Shaft is connected with the input shaft of reduction box 25, and reduction gearbox output shaft 14 is connected with driving wheel 15, and driving rope 23 is fixed on driving wheel On 15, and the both ends of rope are driven to be connected respectively with follower 27, driving platform 12 installs hinge below by two bearing blocks 9 Axle 8, and the both ends bearing shell fixator 7 of hinge axis 8 is fixed on upper mounting plate 11, and driving platform 12 sets a tune loaded van further below 12, to adjust the weight of driving platform, when making oil pumper normal operation, driving platform around hinge axle rotates, and driving wheel two When the driving force difference of the driving rope on side is 1/2 oil column weight, the tractive force of sucker rod pull rope and ballast box pull rope is equal, reaches To balance, energy-saving effect is optimal, and pumping operation is realized in motor rotating under the control of electrical control cubicles.
