Abstract
The utility model relates to an improvement on the basis of the existing conventional type beam pumping unit. The utility model is characterized in that both ends of the beam are provided with horse heads. The horse heads which are arranged at both ends are connected with a reducer which is positioned in a bracket of the middle part of the beam through a rotary plate and a connecting rod, and therefore, the alternate actions upward and downward can be obtained. The utility model realizes that one pumping unit can complete high efficient of oil pumping of two wells simultaneously. The utility model is especially suitable for producing in an oil field with dense oil wells.
Description
The utility model relates to the ground installation of rod pumping system, particularly beam pumping unit.
The conventional type beam pumping unit, it is configured to: walking beam links by bearing support and the support that is installed on a top of the trellis in the middle part, one end of walking beam is installed horse head, the other end is the crossbeam of symmetry, be retarder under the crossbeam, the connecting rod that is symmetricly set on the retarder both sides makes crossbeam link to each other with retarder, under motor driving, connecting rod makes walking beam around a top of the trellis swing, thereby makes horse head obtain to pump.After on the horse head sucker rod being installed, the sucker rod that stretches in the well moves thereupon, realizes that oil pumping row takes out.At the oil extraction operation scene, on a bite oil well, just need an above-mentioned pumping unit.In some oil field, Jianghan Oil-field for example, oil well distributes closelyer on the blocks of oil field, often has at a distance of less than 10 meters oil well, concentrates in the small range as the honeycomb hole.Under this situation, move the position oil pumping, like this with must needing many pumping units or a bite well a bite well, the equipment that the former takies is many, and the latter makes the oil pumping time decreased because of moving the position loading and unloading, and all will expend beam workers such as a lot of transportations and installation the time, all make cost of production higher inevitably.
The purpose of this utility model is to provide a kind of two horse head beam pumping units that are suitable for intensive oil well, realizes that a pumping unit finishes the oil pumping work of two mouthfuls of wells simultaneously.
The utlity model has walking beam, support, horse head, overhang, connecting rod, rotating disk, motor and retarder, described walking beam links by a bearing support and a top of the trellis in the middle part, motor links by belt and retarder, retarder is positioned at support, respectively connects a rotating disk on the output shaft that stretch out outside support on its both sides, and respectively there is a horse head at the two ends of walking beam, there is an overhang that stretches to every limit rotating disk the side of walking beam near the horse head, the connecting rod on every limit, an end links to each other with rotating disk, and an end links to each other with overhang.Under motor driving, there is the rotating disk of crank effect to make connecting rod drive the walking beam swing by overhang, make the horse head that is positioned at the walking beam two ends obtain up-down alternative motion, thereby realize in Liang Kou advances, realizing simultaneously the oil pumping oil extraction.For make walking beam length can because of in the certain limit between two well heads variation of distance obtain corresponding adjustment, also be provided with feed screw nut's controlling device that horse head is moved forward and backward at the two ends of walking beam.
The utility model makes full use of mechanism's working stroke, and a machine is finished the oil pumping work of two mouthfuls of wells simultaneously, and efficient greatly improves, and cost of production obviously descends, and is specially adapted to the intensive oil field of oil well.If only on the horse head of one side, sucker rod is installed, can be used as existing conventional type pumping unit again and use.
Below in conjunction with the accompanying drawing embodiment that has a talk.
Fig. 1 is the utility model plan view.
Fig. 2 is the utility model right elevation.
In walking beam 1 medium position installation shaft bearing 2, mat and support 3 tops connect.Horse head 5 lock onto two ends of walking beam by bolt 6, between horse head and the walking beam, feed screw nut's controlling device 7 is installed.About near the walking beam of two ends horse heads two, each installs an overhang 4, and the length of overhang should be concordant with the outerplanar of following rotating disk.The central axis bearing of coincideing with walking beam middle part bearing support is installed at the top of support 3, with synthetic movable hinged.Retarder 8 is installed in the support, motor 12 links by belt 13 and retarder, motor, retarder and support all are fixed on the base 9, the retarder left and right sides is stretched out on the outer output shaft of support and is respectively loaded onto rotating disk 10, the connecting rod 11 on both sides, one end is connected in the appropriate location on the rotating disk, and the other end links to each other with overhang.
Claims (2)
1. two horse head beam pumping units, have walking beam, support, horse head, overhang, connecting rod, rotating disk, motor and retarder, described walking beam links by a bearing support and a top of the trellis in the middle part, motor links by belt pulley and retarder, it is characterized in that: retarder is positioned at support, respectively connect a rotating disk on the output shaft that stretch out on its both sides outside support, respectively there is a horse head at the two ends of walking beam, there is an overhang that stretches to every limit rotating disk the side of walking beam near the horse head, the connecting rod on every limit, one end links to each other with rotating disk, and an end links to each other with overhang.
2. according to claim 1 pair of horse head beam pumping unit is characterized in that, has feed screw nut's controlling device that horse head is moved forward and backward on the described walking beam.
