Description

Last camber line rolls and becomes rail counter weight type walking beam oil pumping balancing machine

Technical field

The utility model belongs to the oil recovery machiner technical field.

Background technology

At present, known oil exploitation has more than 100 year history, from power consumption, cost, stable equal angles is set out, still do not have to replace this mechanical like product fully, but the main deficiency of beam-pumping unit is that counterbalance effect is undesirable, because dynamic load(loading) constantly fluctuates widely even occur negative load when sucker rod falls, when sucker rod when lower dead center is moved, the main mechanical kinetic energy that relies on deadweight and motor to provide, when sucker rod walks to lower dead center, synthetic potential energy makes sucker rod produce periodically pause and transition in rhythm or melody, and mechanical wear has increased the idle kinetic energy loss when next stroke is initial when strengthening.Sucker rod is the main acting process of oil pumper when top dead centre moves by lower dead center, and this moment, kinetic energy mainly relied on motor, gearbox to drive the counterweight crank and provide.Sucker rod oil pumper counterweight crank when lower dead center is in revolution top dead centre place simultaneously, and the crank of this moment is perpendicular to crank axle, and power moment is zero, and peak value power consumption appears in motor, the gearbox wearing and tearing increase.

Summary of the invention

The purpose of this utility model is: a kind of camber line rolling change rail counter weight type walking beam oil pumping balancing machine of going up is provided, it not only increases, reduces counterbalance moment in real time automatically under no additional power prerequisite, realize the kinetic energy compensation of no additional power, reduced the mechanical movement energy consumption simultaneously effectively.

The technical solution of the utility model is: at oil pumper walking beam afterbody installation curve guide rail as power arm torque adjusting end, top of the trellis at beam-pumping unit is installed the balanced connecting rod support, as the fixed point that drives the counterweight roller, the counterweight roller is installed on guide rail, as the counterweight counterweight, between counterweight roller and balanced connecting rod support, balanced connecting rod is installed, as being connected between counterweight roller and the balanced connecting rod support, power transmission, position-limit mechanism.

The beneficial effects of the utility model are: on the basis that need not the additional power input, changed the counter weight construction of beam-pumping unit, obtained energy-saving and cost-reducing result, the lever machinery principle that meets simple in structure, energy-saving and cost-reducing function is obvious, running cost and fault rate are low, have wide range of applications installation, debugging, easy to maintenance.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1, the 1st, oil well casing, the 2nd, oil pumper support, the 3rd, crank gearbox, the 4th, sucker rod, the 5th, horse head, the 6th, oil pumper walking beam, the 7th, balanced connecting rod support, the 8th, idler-wheel connecting-rod, the 9th, counterweight roller, the 10th, curvilinear guide, the 11st, crank connecting link, the 12nd, oil pumper counterweight crank, the 13rd, motor, the 14th, balancing weight.

Utilize the lever machinery principle, in oil pumper walking beam pitching acting process, changing balancing weight provides the kinetic energy compensation and reduces mechanical wear the resistance arm end in the moment on the power arm and between fulcrum.In the stroke of sucker rod whereabouts this machine counterweight roller along curvilinear guide to distal movement, and then gradual increase counterbalance moment, fall the inertial load that potential energy produces after rise with the gravity of offsetting by sucker rod, make oil pumper steadily enter next stroke with balanced power, in the sucker rod upward stroke starting stage, the counterweight roller is in the moment distal-most end of curvilinear guide and fulcrum.Can be for oil pumper provide kinetic energy in the maximum magnitude of sole mass, loss of motor on-peak electric energy and mechanical wear when slackening the zero moment zone of crank.Along with the rotary kinetic energy of crank increases, the counterweight roller moves thereby counterbalance moment reduces to the fulcrum near-end along curvilinear guide, and the sequential-type power that has continued oil pumper reposefully continues, and has reached energy-conservation, consumption reduction purpose.

In Figure of description Fig. 1, curvilinear guide 10 be connected with oil pumper walking beam 6 afterbodys (adopt be connected firmly), counterweight roller 9 is installed on curvilinear guide 10 tops, balanced connecting rod support 7 (adopt firmly and connect) is installed at oil pumper support 2 tops, with idler-wheel connecting-rod 8 counterweight roller 9 being carried out the through-drive formula with balanced connecting rod support 7 is connected. and counterweight roller 9 is can be according to counterweight amount needs, Weight-adjustable roller at roller shaft two ends increase and decrease balancing weight 14. when oil pumper walking beam 6 drives under crank connecting link 11 drives of crank gearbox 3 drives at motor 13, when carrying out reciprocating, counterweight roller 9 is subjected to the fixed point of idler-wheel connecting-rod 8, the passive driving of balanced connecting rod support 7, with the top of balanced connecting rod support 7 and the connecting axle of idler-wheel connecting-rod 8 is the center of circle, horizontal movement length with counterweight roller 9 is the interval again, carrying out arc line reciprocating along curvilinear guide 10 moves, the counterweight roller 9 motion supporting parts of curvilinear guide 10 are last arc, increased the stroke of counterweight roller 9, reduced counterweight roller 9 carry out far away in up resistance during displacement.The real-time non-isometric power counterweight of counterweight roller 9 on curvilinear guide 10 compensated the mechanical kinetic energy in the negative power zone of counterweights such as the circumference of oil pumper counterweight crank 12 is non-. under the condition of no additionaling power, realized kinetic energy output.

In Figure of description Fig. 2, when sucker rod 4 walked to lower dead center in oil well casing 1, counterweight roller 9 was in the horizontal moment distal-most end of curvilinear guide 10.By near overcome to the motion far away sucker rod 4 in oil well casing 1 because of gravity falls the mechanical pause and transition in rhythm or melody that potential energy produces after rise, provide long moment kinetic energy output when initial for next stroke simultaneously.

In Figure of description Fig. 3, when sucker rod 4 walked to top dead centre in oil well casing 1, counterweight roller 9 was in the horizontal moment most proximal end of curvilinear guide 10.In motion from far near, the moment degression type counterweight of counterweight roller 9 is connected with the swinging counterweight of oil pumper counterweight crank 12, has increased kinetic energy output and has cut down the loss of peak value mechanical energy.

At Figure of description 2, among Fig. 3, counterweight roller 9 with curvilinear guide 10 as work supporting part, with Fig. 2 place is initial point, with Fig. 3 place is the interregional of terminal point, elevating movement with oil pumper walking beam 6, be subjected to the fixed point of idler-wheel connecting-rod 8, the passive driving of balanced connecting rod support 7, do reciprocating. curvilinear guide 10 is as the power arm section of oil pumper walking beam 6, the change in location of counterweight roller 9 on curvilinear guide 10 is to finish simultaneously with the elevating movement of oil pumper walking beam 6, its dynamic effect that oil pumper walking beam 6 is executed is under the certain prerequisite of counterweight roller 9 weight, changes it and produces in the power arm end moments, so be referred to as moment counterweights such as in real time non-.
