Detailed description of the invention
Detailed description for the present invention and technology contents, coordinate accompanying drawing to illustrate as follows, but accompanying drawing only provides reference and purposes of discussion, is not used for the present invention is any limitation as.
According to Fig. 1, machine many wells economical pumping unit, including frame 7, base 5, bridge-type crank mechanism；Described frame 7 bottom is connected for hinge type with base 5, and in frame 7, epimere is supported by tie-strut 10, and these tie-strut 10 two ends are hinged with frame 7 and base 5 respectively, makes three above pin joint form triangular structure；Described frame 7 top is provided with crown sheave 8, and belt 9 front end walking around crown sheave 8 is connected to oil pumping polish rod, and belt 9 rear end is fixed on belt fixed mechanism 6 after bridge type crank mechanism, and bridge-type crank mechanism is connected to electric driving mechanism by power transmission shaft 14；Described bridge-type crank mechanism is at least serially connected with two sets by power transmission shaft 14, and every suit is by the corresponding oil well of belt 9.
Bridge-type crank structure, it is made up of bearing block 15, crank 13, bent axle 12 and movable pulley 11, bearing block 15 is connected with power transmission shaft 14, crank 13 is connected with keyway with power transmission shaft 14, crank 13 and bearing block 15 are respectively symmetrically installation, movable pulley 11 is arranged on crank 13 end by bent axle 12, and crank 13 is connected with bent axle 12 key slot type；Decelerator 16 is directly connected with crank 13 by power transmission shaft 14, is connected by power transmission shaft 14 between oil pumper unit crank 13.Utilize bridge-type crank structure, the difference according to crank phase angle, by rod-pumped well number by 360 ° of deciles, between many wells, utilize the different indexings at crank phase angle to balance each other.Indexing balance makes the moment of torsion superposition of many wells, more steadily, reduces motor installed power, improves oil pumper operational reliability；Meanwhile, indexing balancing technique makes many wells machine application well number no longer by the restriction of odevity.
Linkage between oil pumper unit is realized by power transmission shaft 14, power transmission shaft 14 is made up of more than one piece, mainly do two kinds of connection, one is to connect unit crank 13 and power source, as driving shaft, the output shaft of decelerator 16 overlaps with power transmission shaft 14, and a kind of crank 13 being to connect two frame units, as driven axle.
As shown in the figure, oil well 1, oil well 2, oil well 3, oil well 4, the work process of the present invention is described for four well machines (motor both sides respectively connect two frame oil pumper units) below: (1) starts motor 17 makes a derrick polished rod eye of side be in lower dead point position, brake is stopped extremely, hang required weight as requested；(2) releasing of brake, starts motor 17, makes crank 13 half revolution (polished rod eye now having hung counterweight is in upper dead center position, and the polished rod eye of another derrick of homonymy is in lower dead point position), brake stopped extremely, hang required weight as requested；(3) start motor 17, make crank 13 rotate 1/4 week, brake is stopped extremely.Repeat step 1 and 2 at opposite side, make the polished rod eye of two other mouth well hang up the weight of requirement；(4) unclamp parking brake, start motor 17.Thus, each well is connected as a single entity by power transmission shaft 14, and many wells load balances each other, drives belt 9 to move reciprocatingly, it is achieved each well normally produces.
The foregoing is only presently preferred embodiments of the present invention, be not used to limit the scope of the claims of the present invention, other use the equivalent of patent spirit of the present invention to change, and all should all belong to the scope of the claims of the present invention.
