Embodiment

Fig. 1 ~ 5 are most preferred embodiments of the present utility model, and 1 ~ 5 pair of the utility model is done furtherly below in conjunction with the accompanying drawings It is bright.

As shown in Figure 1 and 2, the more well gang pumping units of cluster well, including the multigroup oil-producing unit being arranged side by side, each group Oil-producing unit include frame 2 and with the one-to-one runner drive mechanism 4 of frame 2, be provided with rotatably at the top of frame 2 Crown sheave 1, the one end of belt 3 is fixed in runner drive mechanism 4, the other end from the top of crown sheave 1 around after with setting Rod string in the front end of frame 2（It is not drawn into figure）It is connected.Runner drive mechanism 4 drives belt 3 to move back and forth when rotating, Pull rod string in the vertical direction up and down reciprocatingly to act while belt 3 moves back and forth, realize oil pumping.

In the more well gang pumping units of this cluster well, oil-producing unit has been arranged side by side four groups, and four groups of oil-producing units are simultaneously It is fixed in the fixed plate 6 of the top of ground 7.Actuating unit 8 is provided with the middle part of four groups of oil-producing units, automatic force mechanisms 8 Output shaft is connected with line shaft 5, and line shaft 5 extends and is connected simultaneously with the runner drive mechanism 4 of its both sides to the left and right sides, Realized by actuating unit 8 and provide power simultaneously for four groups of runner drive mechanisms 4.

As shown in figure 3, actuating unit 8 includes the fixed station 9 for being fixed on the surface of fixed plate 6, fixed station 9 is that height is different Two ranks are designed, and motor 10 is fixed with low order platform, decelerator 13 is fixed with high-order platform, motor 10 It is attached between output shaft and the decelerator wheel for inputting 12 of decelerator 13 by transmission belt 11.The decelerator output of decelerator 13 Axle 14 is located at the rear of the shell of decelerator 13, and is drawn simultaneously from left and right two end faces of decelerator 13, connects respectively after extraction Connect a line shaft 5.

As shown in Fig. 4 ~ 5, runner drive mechanism 4 includes two runner fixed mounts 17 being arranged side by side, in runner fixed mount 17 inner side is respectively fixed with a rotatable runner 16, is consolidated between two runners 16 being oppositely arranged by connecting shaft 15 Fixed connection.The outer ring of runner 16 is provided with the gear teeth, the position corresponding with each runner 16 is coaxially fixed on line shaft 5 There is the gear that the gear teeth with the outer ring of runner 16 are meshed, line shaft 5 turns when rotating by being coaxial therewith fixed gear driving Wheel 16 rotates.

The outer cover of connecting shaft 15 between runner 16 is equipped with retainer ring, and above-mentioned belt 3 is fixed in the retainer ring.When When connecting shaft 15 turns to the distal end of belt 3 with runner 16, rod string is promoted to by peak by belt 3, works as connecting shaft 15 when turning to the near-end of belt 3 with runner 16, minimum point when rod string falls.

As described above, four groups of runner drive mechanisms 4, four groups of runners are provided with the more well gang pumping units of this cluster well The axis of totally eight runners 16 in drive mechanism 4 overlaps, and totally four connecting shafts 15 in four groups of runner drive mechanisms 4 Axis is distributed on the outside of runner 16, i.e., the angle that the axis of two connecting shafts 15 of arbitrary neighborhood and the axis of runner 16 are in is 90°.Because the rectangular form of the axis of two connecting shafts 15 of arbitrary neighborhood is staggered, therefore four groups of runner drive mechanisms 4 Runner 16 during rotation, rod string that each runner drive mechanism 4 is pulled alternately is promoted to peak （Minimum point is dropped down onto under or）, therefore the rod string in dropping process is aligned by belt 3, runner 16 and line shaft 5 Rod string in propradation provides certain power, i.e. each rod string is during rising except receiving Also respectively by the power to other rod strings, therefore carried required for motor 10 outside the power provided to line shaft 5 The power of confession substantially reduces, so as to save energy consumption.Obtain through many experiments, when runner drive mechanism 4 is arranged to four groups, drive The power provided required for dynamic motor 10 is minimum, in optimal working condition.

Specific work process and operation principle are as follows：

When needing to be recovered the oil using rod string, motor 10 rotates, and motor 10 passes through while rotation Transmission belt 11 drives decelerator 13 to rotate, and the line shaft 5 being connected on reducer output shaft 14 while rotates.Line shaft 5 is turning By being coaxial therewith fixed gear while driving four groups of runners 16 in four groups of runner drive mechanisms 4 to rotate while dynamic.Turn When rotating, being fixed on the connecting shaft 15 at any one group of middle part of runner 16 can be pulled wheel 16 by being sleeved on its outside connection ring Belt 3.Belt 3 pulls corresponding rod string to move back and forth after pulling force is received by the crown sheave 1 above frame 2.

When connecting shaft 15 turns to the distal end of belt 3 with runner 16, rod string is promoted to by highest by belt 3 Point, when connecting shaft 15 turns to the near-end of belt 3 with runner 16, minimum point when rod string falls, and it is in dropping process In rod string by belt 3, runner 16 and line shaft 5 align the rod string in propradation provide it is certain Power, therefore the four rod strings meeting in the vertical direction driven by four groups of runner drive mechanisms 4 moves back and forth, so as to complete Recover the oil.

In the more well gang pumping units of this cluster well, line shaft 5 is directly connected to from reducer output shaft 14, and by dynamic Power axle 5 directly drive oil-producing unit in runner drive mechanism 4 rotate, therefore between transmission link it is few, greatly reduce Loss in transmission process, improve the utilization rate of power.

It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent The equivalent embodiment of change.But it is every without departing from the content of the technical scheme of the utility model, it is real according to technology of the present utility model Any simple modification, equivalent variations and the remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model Protect scope.
