The specific embodiment
Relevant detailed description of the present invention and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides the use of reference with explanation, is not used for the present invention to be limited.
Shown in Fig. 1, many wells of machine economical pumping unit, comprises frame 7, base 5, bridge-type crank mechanism; Described frame 7 bottoms are with base 5 for hinge type is connected, and in frame 7, epimere supports by tie-strut 10, and these 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, and belt 9 rear ends are fixed on belt fixed mechanism 6 after walking around 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 covers by power transmission shaft 14, and every suit is by the corresponding oil well of belt 9.
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 is directly connected with crank 13 by power transmission shaft 14, between oil pumper unit crank 13, connects by power transmission shaft 14.Utilize bridge-type crank structure, according to the difference at crank phase angle, by 360 ° of deciles, between many wells, utilize the different indexings balance each other at crank phase angle by rod-pumped well number.Indexing balance makes the stack of many wells moment of torsion, more steady, reduces motor installed power, improves oil pumper operational reliability; Meanwhile, indexing balancing technique makes many wells machine application well number no longer be subject to the restriction of odevity.
Linkage complete between 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, one 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.
As shown in the figure, oil well 1, oil well 2, oil well 3, oil well 4, as an example of four well machines (two oil pumper units of the each connection in motor both sides) example, the course of work of the present invention is described below: (1) starter motor 17 makes a derrick polished rod eye of a side in lower dead point position, brake is stopped extremely, hang as requested desired weight; (2) releasing of brake, starter motor 17, makes crank 13 rotate half cycle (now hung the polished rod eye of counterweight in upper dead center position, the polished rod eye of another derrick of homonymy is in lower dead point position), and brake is stopped extremely, hangs as requested desired weight; (3) starter motor 17, rotates crank 13 1/4 week, and brake is stopped extremely.At opposite side repeating step 1 and 2, make the polished rod eye of another two mouthfuls of wells hang up the weight of requirement; (4) unclamp parking brake, starter motor 17.Thus, each well is connected as a single entity by power transmission shaft 14, and many wells load balance each other drives belt 9 to move reciprocatingly, and realizes each well and normally produces.
The foregoing is only preferred embodiment of the present invention, non-in order to limit the scope of the claims of the present invention, other use the equivalence of patent spirit of the present invention to change, and all should all belong to the scope of the claims of the present invention.
