Among the figure: 1 walking beam, 2 horse heads, 3 outstanding ropes, 4 supports, 5 walking beam axis, 6 walking beam counterbalances, 7 connecting rods, 8 crankwebs, 9 crank counterbalances, 10 walking beam bearings, the first portion of 11 walking beams, the second portion of 12 walking beams, 13 walking-beam counterweights, 14 walking beam counterbalance supporting elements, 15 pins.
Embodiment
Shown in Figure 1 according to oil pump suction device of the present utility model, it comprises the power plant such as motor; Motor is connected to crankweb 8 by belt and gear reducer, and crankweb 8 is around the rotation of the fixed axis at one end place, at the free end of crankweb 8 crank counterbalance 9 is installed; Crankweb 8 is hinged with a connecting rod 7 between its free end and fixed end, and the other end of this connecting rod 7 is connected to walking beam 1; Described walking beam 1 is supported by a walking beam support 4 and can pivot around the bearing 10 that is arranged on walking beam support 4 upper ends; At the front end place of described walking beam 1 horse head 2 is installed; Described walking beam 1 comprises a first portion 11 that links to each other with horse head 2 and a second portion 12 that links to each other with walking beam counterbalance 6.
The barycenter of walking beam counterbalance offsets away with respect to walking beam axis horizontal (be parallel to plane shown in Figure 1 and perpendicular to the direction of walking beam axis).Begin and down stroke when end in upstroke, walking beam counterbalance swings near the peak, and the gravity of walking beam counterbalance is bigger with respect to the arm of force of bearing, and promptly the counter balance torque of walking beam counterbalance is bigger, thus balance bigger polished rod load this moment preferably.When upstroke end and down stroke began, walking beam counterbalance swung near the minimum point, and the gravity of walking beam counterbalance is less with respect to the arm of force of bearing, and promptly the counter balance torque of walking beam counterbalance is less, thus the at this moment less polished rod load of balance preferably.Improved the balance to polished rod load like this, the peak value and the valley that help to reduce polished rod load are poor, thereby have improved balance, have improved efficiency.
Shown in the property, described first portion 11 tightens together by being threaded mutually with described second portion 12 as schematically shown in Figure 1.Thereby each first portion 11 and second portion 12 length separately are significantly smaller than whole walking beam, and weight separately is significantly smaller than whole walking beam.This is for remote transportation walking beam and oil well is installed in the open air is very favourable.
In a preferred embodiment of the present utility model, the second portion 12 of described walking beam 1 is provided with a plurality of through holes of being threaded with first portion 11 of being used for.Be provided with a plurality of along the direction distribution tapped hole that is parallel to the walking beam axis in described first portion 11.When the bolt that passes through hole on the second portion 12 was screwed in different tapped hole in the first portion 11, second portion 12 was different with respect to the axial position of first portion.Alternatively, also can in described first portion, slit be set or through hole is realized identical technique effect.
Similarly, described crank counterbalance can be arranged to its barycenter with respect to the adjustment of crankweb axis.
Because second portion 12 connects walking beam counterbalance 6, so the change of described relative axial position causes walking beam counterbalance 6 to change with respect to the axial position owing to walking beam, thus the size and the phase place of regulating counter balance torque that walking beam counterbalance produces.Simultaneously, because second portion 12 is hinged with connecting rod 7, so, the change of described relative axial position causes the distance of connecting rod 7 between articulating point on the walking beam and walking beam bearing 10 to change, thereby changed the length of an arm in the quadratic crank mechanism, caused polished rod load to change by the load-torque that described quadratic crank mechanism acts on the crankweb.
In a further preferred embodiment of the present utility model, between the first portion 11 of described walking beam 1 and second portion 12, be provided with screw-nut structure and regulate position to axial between described two parts.For example leading screw is fastened in the first portion, and will be fastened on the second portion with the supporting nut of leading screw.Have screw pass the through hole in the second portion and in first portion, be provided be parallel to the axial pod of walking beam, fastening at the place, end of screw with tightening nut, thus the second portion of described walking beam is fastened in the first portion.When needs are regulated walking beam second portion 12 with respect to the axial position of first portion 11, suitably unscrew described tightening nut, make that second portion can be with respect to first portion's longitudinal movement, rotating threaded shaft then, the second portion of walking beam is adjusted to required axial positions, tighten described tightening nut then, the walking beam second portion is firmly fastened in the first portion of walking beam.
As shown in Figure 1, described first portion 11 and second portion 12 all are rectilinear, thereby make easily, for example can be by the section bar manufacturing of H steel and so on.
The walking beam counterbalance supporting element 14 of downward extension is installed at second portion 12 rear portions of walking beam.Because on the second portion of walking beam, be provided with multiple row through hole or tapped hole (7 row shown in Fig. 2, shown in the center line among the figure), so walking beam counterbalance supporting element 14 can be installed on the described second portion 12 with a plurality of different positions (press shown in Fig. 2,4 different positions can be arranged) on walking beam is axial.Walking beam counterbalance 6 is installed on the walking beam counterbalance supporting element 14.Walking beam counterbalance 6 comprises a plurality of walking-beam counterweights 13.Walking-beam counterweight 13 be shaped as the disk that has center hole, be connected on the second portion of walking beam by means of the pin 15 that passes supporting element 14.Can be provided with a plurality of holes that pin 15 passes that are used on the supporting element 14, with the barycenter that changes walking beam counterbalance 6 by the position that changes pin 15 with respect to the lengthwise position of walking beam axis and horizontal (be parallel to plane shown in Figure 1 and perpendicular to the direction of walking beam axis) position.The shape of walking-beam counterweight also can be other shape, for example square, rectangular etc.Described walking-beam counterweight also can adopt other mode to be connected to the second portion of walking beam, for example is connected on the supporting element by two pins, perhaps is connected directly on the walking beam.
At needs oil pump of the present utility model being inhaled device adjusts, when acting on moment of torsion on the crankweb with the balance polished rod load, can adjust the walking beam second portion with respect to the axial position of walking beam first portion, walking beam counterbalance center with respect to the walking beam second portion axially and lateral attitude and crank counterbalance with respect to the drift angle of crankweb and with respect to the distance of crank spin axis.
