Abstract

A self-torque moving balance oil pumping unit substantially solves the problem of that high power consumption of generators due to the matching blocks of the existing oil pumping units can not move. The utility model is characterized in that a balance beam (2) is coating seated with a movable matching block (6), both sides of the rear of the balance beam (2) are provided with orbits (3), the movable matching block (6) is hinge connected with a rack (8) fixed on a frame (1) through a binding rod (7), a wheel (5) fixed by a shaft (4) on the movable matching block (6) is sliding engaged with the orbits (3). The oil pumping unit has the advantages of that the matching block can move automatically and the generator has low power consumption.

Description

From bending moment shifting balance oil pumper

Technical field:

The utility model relates to the used oil pumper in oil recovery field, oil field, especially from bending moment shifting balance oil pumper.

Background technology:

Oil pumper is a kind of capital equipment that the oil field machine is adopted, and mainly by motor, gearbox drive crank, connecting rod walking beam is moved up and down, and reaches the purpose of oil recovery.Present oil pumper is because walking beam two ends load difference is bigger, though balancing weight is arranged now, but all be on being fixed on a bit, balancing weight can not move, so just exist and to drive sucker rod than heavy-duty motor when carrying and move upward, and need less power motor or unpowered when falling, and just make motor power consumption height, the wasting of resources thus, make cost for oil production increase.

The utility model content:

Can not move and cause the high deficiency of motor power consumption, the utility model to provide a kind of from bending moment shifting balance oil pumper in order to overcome existing oil pumper balancing weight, this oil pumper has the advantages that balancing weight can move automatically, motor power consumption is low.

Technical solutions of the utility model are: should comprise support and walking beam from bending moment shifting balance oil pumper, walking beam is fixed on the support, two sides of tail has that block set has self-balanced upper rotary on the walking beam of track, self-balanced upper rotary is hinged by fixed mount fixing on connecting rod and the support, and the fixing wheel of axle on the self-balanced upper rotary moves with track and cooperates.

The utlity model has beneficial effect is: owing to from bending moment shifting balance oil pumper block set on the walking beam afterbody self-balanced upper rotary is arranged, self-balanced upper rotary links to each other with fixed mount on connecting rod and the support respectively by hinged, self-balanced upper rotary can move to the walking beam front end when upstroke, the load difference reduces before and after making its walking beam, reduced the power of motor, when the moving balancing weight of down stroke time shift can move to the walking beam rear end, put aside energy, so just reach balancing weight and can move, reduce motor power consumption automatically.

Description of drawings:

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is the utility model A-A sectional views.

1-support among the figure, 2-walking beam, 3-track, 4-axle, 5-wheel, 6-self-balanced upper rotary, 7-connecting rod, 8-fixed support.

The specific embodiment:

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

By Fig. 1 in conjunction with shown in Figure 2, should comprise support 1 and walking beam 2 from bending moment shifting balance oil pumper, walking beam 2 is fixed on the support 1, both sides, walking beam 2 afterbody lower end have track 3, block set self-balanced upper rotary 6 on walking beam 2 tracks 3, and self-balanced upper rotary 6 is hinged with connecting rod 7, connecting rod 7 is hinged with fixed mount 8, fixed mount 8 is fixed on the support 1, makes self-balanced upper rotary 6 and fixed mount 8 be hinged to one by connecting rod 7, and self-balanced upper rotary 6 can move forward and backward at walking beam 2 afterbodys; Both sides are fixed with wheel 5 by axle 4 before and after in self-balanced upper rotary 6 square holes, wheel 5 decks are on track 3, make wheel 5 and self-balanced upper rotary 6 link into an integrated entity, on walking beam 2 tracks 3, can move, reach self-balanced upper rotary 6 and can move, reduce motor power consumption automatically.

During actual the use, fixed mount 8 is fixed on the support 1, makes fixed mount 8 and self-balanced upper rotary 6 hinged by connecting rod 7, wheel 5 block sets can be used on walking beam 2 afterbody tracks 3 in self-balanced upper rotary 6 square holes.

Claims

1, a kind of from bending moment shifting balance oil pumper, comprise support (1) and walking beam (2), walking beam (2) is fixed on the support (1), it is characterized in that: the last block set of walking beam (2) that two sides of tail has track (3) has self-balanced upper rotary (6), self-balanced upper rotary (6) goes up fixing fixed mount (8) by connecting rod (7) and support (1) and is hinged, and the fixing wheel (5) of the axle (4) on the self-balanced upper rotary (6) moves with track (3) and cooperates.
