Description

Balanced oil extractor floats

Technical field

The utility model relates to a kind of oil pumper, especially relates to a kind of unsteady balanced oil extractor.

Background technology

At present; The balance mode that known oil pumper adopts mainly contains crank balance, beam balance, plural equilibrium; This balance mode all adopts the balance weight suitable with oil pumper load to carry out balance, and inertia force is bigger during switching-over, causes the oil pumper unsafe factor; And the system balancing inefficiency makes oil pumper labor electric energy.

Summary of the invention

Big, the deficiency that has unsafe factor, system balancing inefficiency, labor electric energy of inertia force when overcoming the switching-over of existing oil pumper, the utility model provides a kind of unsteady balanced oil extractor.

The utility model solves the technical scheme that its technical problem adopted: a kind of unsteady balanced oil extractor, comprise the carrier fluid cylinder that axis is parallel to each other, and the carrier fluid cylinder is used to load buoyancy liquid; In each carrier fluid cylinder guide rail and float are installed, guide rail is used for the correcting float, and buoys float is on buoyancy liquid; Respectively be mounted with support bar and drive chain on each float, supporting bar top is installed in the two ends of crossbeam, and an end of every drive chain is fixed on the float; The other end is fixed on the crossbeam, on the carrier fluid cylinder wheel assembly is installed, and is provided with one group of driving wheel under the wheel assembly excessively; Wherein one group of driving wheel is installed in an end of driver, and the driver other end is equipped with one group of transmission wheel, transmits wheel and is connected by transfer chain; Transfer chain axis and crossbeam axis be not on same vertical plane and do not have an intersection point; The axle center of the polished rod hanger of installing on the crossbeam is transmitted wheel and is had two groups on the axis of crossbeam, and another group is transmitted the end that wheel is installed in commutator; The commutator other end be equipped with another the group driving wheel, between two carrier fluid cylinders with joining communicating pipe.

Further specify: carrier fluid cylinder, float, support bar, drive chain, mistake wheel assembly, driving wheel, transmission wheel respectively have two groups respectively, divide to be listed in the two ends of crossbeam, the both sides of polished rod hanger.Form an independently system by one group of carrier fluid cylinder, float, support bar, drive chain, mistake wheel assembly, driving wheel, transmission wheel respectively at either side; Then with two systems incorporate together by transfer chain; The float at two ends is done up and down to be synchronized with the movement; Drive crossbeam through support bar and do and pump, crossbeam drives downhole tool through the polished rod hanger crude oil is given rise to ground.

The beneficial effect of the utility model is:

Balance efficiency is high, little, the saves energy of switching-over inertia force.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Like Fig. 1,2, shown in 3, the utility model comprises the carrier fluid cylinder 1 that axis is parallel to each other, and carrier fluid cylinder 1 is used to load buoyancy liquid; Guide rail 2 and float 3 are installed in each carrier fluid cylinder 1, and guide rail 2 is used for correcting float 3, and float 3 swims on the buoyancy liquid; Respectively be mounted with support bar 4 and drive chain 5 on each float 3, support bar 4 tops are installed in the two ends of crossbeam 6, and an end of every drive chain 5 is fixed on the float 3; The other end is fixed on the crossbeam 6, and wheel assembly 7 was installed on the carrier fluid cylinder 1, is provided with one group of driving wheel 8 under the wheel assembly 7 excessively; Wherein one group of driving wheel 8 is installed in an end of driver 9, and driver 9 other ends are equipped with one group of transmission wheel 10, transmits wheel 10 and is connected by transfer chain 11; Transfer chain 11 axis and crossbeam 6 axis are not on same vertical plane and do not have intersection point, and the axle center of the polished rod hanger of installing on the crossbeam 6 12 is transmitted wheel 10 and had two groups on the axis of crossbeam; Another group is transmitted the end that wheel 10 is installed in commutator 13, and commutator 13 other ends are equipped with another group driving wheel 8.Join with communicating pipe 14 between two carrier fluid cylinders 1.

Carrier fluid cylinder 1, float 3, support bar 4, drive chain 5, mistake wheel assembly 7, driving wheel 8, transmission wheel 10 respectively have two groups respectively, divide to be listed in the two ends of crossbeam 6, the both sides of polished rod hanger 12.Form an independently system by one group of carrier fluid cylinder 1, float 3, support bar 4, drive chain 5, mistake wheel assembly 7, driving wheel 8, transmission wheel 10 respectively at either side; Then with two systems incorporate together by transfer chain 11; Under the effect of driver 9, driving drive chain 5 makees up and down the float 3 at two ends to be synchronized with the movement simultaneously; Float 3 drives crossbeam 6 through support bar 4 and does and float 3 synchronous pumping, and crossbeam 6 drives downhole tool through polished rod hanger 12 crude oil is given rise to ground.
