The utility model can be realized balance adjustment and the moment of torsion smooth transfer of many wells, satisfies the cluster well group and encrypts the needs of the energy-saving and cost-reducing exploitation of well group.Many well loads adopt crank phase angular indexing technology, have realized many wells balance each other, have improved the energy-saving effect of multiple well pumping unit; Not limited by the well number, the machine of can realizing drives gang pumping.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of bridge-type crank mechanism and drive unit.
In figure: oil well 1, oil well 2, oil well 3, oil well 4, base 5, belt fixed mechanism 6, frame 7, crown sheave 8, belt 9, tie-strut 10, movable pulley 11, bent axle 12, crank 13, power transmission shaft 14, bearing support 15, reducer 16, motor 17.
The specific embodiment
This many wells of machine economical pumping unit comprises frame 7, base 5, bridge-type crank mechanism; For hinge type is connected, in frame 7, epimere supports by tie-strut 10 with base 5 in described frame 7 bottoms, and this tie-strut 10 two ends are hinged with frame 7 and base 5 respectively, make above three pin joints form triangular structure; Described frame 7 tops are provided with crown sheave 8, and belt 9 front ends of walking around crown sheave 8 are connected to oil pumping polish rod, be fixed on belt fixed mechanism 6 after the bridge-type crank mechanism is walked around in belt 9 rear ends, and the bridge-type crank mechanism are connected to electric driving mechanism by power transmission shaft 14; Described bridge-type crank mechanism is serially connected with two covers at least by power transmission shaft 14, and every suit is by the corresponding oil well of belt 9.
The bridge-type crank structure, formed by bearing support 15, crank 13, bent axle 12 and movable pulley 11, bearing support 15 is connected with power transmission shaft 14, crank 13 is connected with power transmission shaft 14 use keyways, crank 13 and bearing support 15 symmetrical installation respectively, movable pulley 11 is arranged on crank 13 ends by bent axle 12, and crank 13 is connected with bent axle 12 key slot types; Reducer 16 directly is connected with crank 13 by power transmission shaft 14, connects by power transmission shaft 14 between oil pumper unit crank 13.Utilize the bridge-type crank structure, according to the difference at crank phase angle, press the rod-pumped well number with 360 ° of deciles, the different indexings that utilize the crank phase angle between many wells are balance each other.The indexing balance makes the stack of many wells moment of torsion, and is more steady, reduces the motor installed power, improves the oil pumper operational reliability; Simultaneously, the indexing balancing technique makes many wells machine use the restriction that the well number no longer is subjected to odevity.
Linkage complete between the oil pumper unit is crossed power transmission shaft 14 and is realized, power transmission shaft 14 forms by many, mainly do the connection of two types, a kind of is to connect unit crank 13 and power source, as driving shaft, the output shaft of reducer 16 overlaps with power transmission shaft 14, and a kind of is the crank 13 that connects two units, as driven axle.
