Description

Изобретение относитс к области оборудовани дл добычи нефти, а именно к групповым приводам штанговых насосных установок.The invention relates to the field of equipment for oil production, and in particular to group drives of sucker rod pump units.

Известен групповой привод штанговых скважинных насосных установок дл обслуживани двух скважин, содержащий приводной двигатель с редуктором, имеющим выходное звено, кинематически св занное с кривошипными механизмами, кривошип каждого из которых соединен с соответствующей подвеской насосной штанги скважины и одновременно с колесом, имеющим наружный зубчатый венец.A group drive of sucker rod pumping units for servicing two wells is known, comprising a drive motor with a gearbox having an output link kinematically connected to crank mechanisms, the crank of each of which is connected to the corresponding suspension of the sucker rod of the well and simultaneously with a wheel having an external gear ring.

Недостатком этого привода вл етс сложность конструкции.The disadvantage of this drive is its design complexity.

Сущность изобретени заключаетс в том, что кривошипные механизмы по числу скважин установлены на общей стойке и расположены последовательно в р д, а зуб- чатые венцы колес каждого кривошипа охвачены общей гибкой св зью в виде бесконечной цепи, при этом одно из колес кривошипов при помощи карданного валаThe essence of the invention lies in the fact that the crank mechanisms by the number of wells are mounted on a common rack and are arranged sequentially in a row, and the toothed rims of the wheels of each crank are covered by a common flexible link in the form of an endless chain, while one of the crank wheels using a universal joint shaft

соединено с выходным звеном редуктора, аconnected to the output link of the gearbox, and

кривошипы D совмещенной проекции на общую плоскость, совпадающую с плоскостью их вращени , установлены последовательно через 120°.the cranks D of the combined projection onto a common plane coinciding with the plane of their rotation are set sequentially through 120 °.

Благодар этому обеспечиваетс воз- можность привода как минимум шести установок , которые могут работать как все шесть одновременно, так и в любом сочетании.Thanks to this, it is possible to drive at least six plants, which can operate as all six at the same time, or in any combination.

На фиг.1 показан общий вид группового привода с трем установками в плане; на фиг,2 - то же, вид спереди; на фиг.З - узел I на фиг.2.Figure 1 shows a General view of a group drive with three settings in plan; in Fig.2 - the same front view; in Fig.Z - node I in Fig.2.

The claims

A GROUP DRIVE OF PUMPING WELL UNITS, comprising a drive motor with a gear having an output link kinematically connected to crank mechanisms, 45 crank of each of which is connected to the corresponding suspension of the pump rod of the well and simultaneously with a wheel having an external gear ring, characterized in that to simplify - 50

The drive contains a drive motor 1 with a gearbox 2 connected to a belt drive motor 3. The output link 4 is connected to the cardan shafts 5. On the common rack 6, crank mechanisms 8 are mounted in series with shafts 7 in series. Cranks in a combined projection onto a common a plane coinciding with their plane of rotation is set sequentially through 120 °. The gear rims of the wheels 9 of each crank are covered by a common flexible link in the form of an endless chain. Each crank 8 is provided with vertical guides 10 in increments. The crank is pivotally coupled to a connecting rod 11 connected to the suspension 12 of the pump rod of the well. A similar drive is mirrored on the other side of the gearbox.

The drive operates as follows.

When the drive is turned on, all six units can work, as well as any combination of them.

When the electric motor is turned on through the gearbox, the movement is transmitted to the cardan shafts spaced on both sides of the gearbox, each of which is connected with breaking the crank. Using a chain drive, the movement is transmitted to the cranks, and then through the connecting rods to the suspension of the sucker rods. The sequential arrangement of the crochets every 120 ° ensures mutual compensation of their movement, with the ego the magnitude of the stroke of each installation does not depend on the others.
