The transmission mechanism for driving elevator 3 to move up and down is additionally provided with frame 1, transmission mechanism is connected with elevator 3.Its
In, first hydraulic cylinder 9 and second hydraulic cylinder 10 that transmission mechanism connects respectively including passing through the port of export of pipeline and fuel tank, first
The piston rod top of hydraulic cylinder 9 is connected with the first sprocket wheel 11 by cross bar, is engaged with the first chain 12 on the first sprocket wheel 11, and first
One end of chain 12 is fixedly connected with frame 1, and the other end is connected with the top of elevator 3.
The piston rod top of second hydraulic cylinder 10 is connected with the second sprocket wheel 13 by cross bar, and the lower section of frame 1 is located at first
The lower section of sprocket wheel 11 is connected with the 3rd sprocket wheel 14 by cross bar, and the second chain 15 is engaged with the second sprocket wheel 13, the second chain 15
One end is fixedly connected with frame 1, and the other end is connected by the 3rd sprocket wheel 14 and the second sprocket wheel 13 with the lower end of elevator 3 respectively.
The accumulator 4 for storing and releasing energy also is fixed with frame 1, the port of export of accumulator 4 passes through pipeline
Energy storage hydraulic cylinder 5 is connected with, the top of the piston rod of energy storage hydraulic cylinder 5 is connected with energy storage sprocket wheel 6, is engaged with energy storage sprocket wheel 6
Energy storage chain 7, one end of energy storage chain 7 are fixedly connected with frame 1, and the other end is connected with the top of elevator 3.Wherein, energy storage sprocket wheel 6
It is highly consistent with the first sprocket wheel 11.Accumulator 4 includes accumulator housing 41, is provided with the accumulator housing 41 and connects with gas cylinder
The air bag 42 connect, hydraulic oil cavity 43 is formed between the air bag 42 and accumulator housing 41, the hydraulic oil cavity 43 passes through
Pipeline is connected with the entrance of energy storage hydraulic cylinder 5.Elevator 3 is realized by the energy auxiliary drive gear of accumulator 4 and moved up and down, so as to
Reach the purpose of energy-conservation.The gas cylinder that air bag 42 connects is nitrogen cylinder.Specifically, the work of energy storage hydraulic cylinder 5 when accumulator 4 works
The upward thrust of stopper rod is transformed into upward pulling force by sprocket wheel chain and is transmitted to polished rod elevator 3, in this pulling force size and nitrogen cylinder
The pressure of nitrogen is directly proportional.The pulling force of chain is stronger on the bigger elevator 3 of reservoir pressure of nitrogen cylinder.Therefore can be by adjusting nitrogen
The pressure of cylinder nitrogen adjusts the dynamic equilibrium of whole oil pumper, has reached energy conservation object.It is typically due to caused by accumulator
Upward pulling force, it is greater than the gross weight of the oil well component suspending weight such as well rod and pump, it is clear that so can not only cause oil pumper
Counterweight tend to desirable balance, can also mitigate the load of pumping-unit motor significantly.
Above-mentioned energy storage sprocket wheel 6, the first sprocket wheel 11, the second sprocket wheel 13 and the 3rd sprocket wheel 14 includes being separately positioned on cross bar
Two sprocket wheels at both ends, chain is engaged with each sprocket wheel.
Operation principle：Elevator uphill process：As shown in Fig. 2 in the motor 2 on starting fuel tank 8, toward the gas of accumulator 4
Inflated in capsule 42, as pressure increases, (the compressed nitrogen in the air bag 42 of accumulator 4, in expansion process, by pressure transmission
To the hydraulic oil in accumulator 4) hydraulic oil in accumulator 4 enters energy storage hydraulic cylinder 5, the work of energy storage hydraulic cylinder 5 by pipeline
The rising of stopper rod upper end, the energy storage sprocket wheel 6 on its top is driven to rotate, wherein, energy storage sprocket wheel 6 is two, is separately positioned on cross bar
Both ends, and two energy storage chains 7 that two energy storage sprocket wheels 6 engage drive elevator 3 to rise；Simultaneously as start fuel tank motor
2, the hydraulic oil in fuel tank 8 enters first hydraulic cylinder 9, two first chains on the piston rod top of first hydraulic cylinder 9 by pipeline
Wheel 11 rotates, and two first chains 12 of two the first sprocket wheel 11 occlusions also drive elevator 3 to rise until top dead centre simultaneously；By
Rise in elevator 3, drive the one end of the second chain 15 for being fixed on its lower end to rise, the second chain 15 is rotated by the second sprocket wheel 13
The piston rod of second hydraulic cylinder 10 is driven to decline, so as to which hydraulic oil is back to fuel tank 8, now the pressure of second hydraulic cylinder 10 is minimum.
Therefore, it is the process that accumulator releases energy in the uphill process of elevator 3, realizes energy-conservation, rather than only lean on first hydraulic cylinder
9 provide lifting power.
Elevator declines process：As shown in figure 3, due to elevator 3 and its self gravitation effect of polished rod 16 of connection, very little is only needed
Power just can realize that elevator 3 declines, second hydraulic cylinder 10 entered by the hydraulic oil in fuel tank 8, then second hydraulic cylinder 10
Piston rod rises, and drives the second sprocket wheel 13 to rotate, and the 3rd sprocket wheel 14 is driven by the second chain 15 engaged on the second sprocket wheel 13
Rotating, the second chain 15 drop-down elevator 3, elevator 3 declines, until lower dead center is dropped to, and during the decline of elevator 3, energy storage chain
The sprocket wheel 11 of wheel 6 and first drops to defined minimum point respectively under the drive of the chain 12 of energy storage chain 7 and first, under elevator 3
Drop process is also that accumulator is the process for storing energy.
Numerically controlled beam-pumping unit has following outstanding feature：
1st, economize on electricity：It can economize on electricity more than 40% compared with traditional beam machine, also be economized on electricity than belt feeder.
2nd, it is in light weight：Its gross weight is only 3.5 tons, and lifting weight can reach 12 tons, can be directly installed on oil well
On production tree.It is to weigh formula well and offshore production platform, preferable regeneration product.
3rd, remote control is realized:The stroke and jig frequency for the oil pumper being currently running can be regulated and controled by network remote.
Pull-up elevator 3 and its polished rod 16 of connection is aided in realize energy-conservation by accumulator, the invention small volume is in light weight,
Simultaneously by numerical control device, remote monitoring activities are realized, ensure that the personal safety of worker, operating efficiency improves.
The present invention is not limited to above-mentioned embodiment, in those skilled in the art's possessed knowledge, may be used also
To be made a variety of changes on the premise of present inventive concept is not departed from, the content after change still falls within protection scope of the present invention.
