Abstract
The utility model provides a beam-balanced and stroke length increasing pumping unit for mechanical oil extraction of oil extraction. The technical characteristics of the utility model are that in the structure of the prior, traditional walking beam type pumping unit, the walking beam of a tail part is additionally provided with a counter weight of an adjustable outphase offset angle, a prior horse head is replaced with an offset wheel which is capable of rotating, a negative connecting rod which is connected with the offset wheel is arranged between a heightening bracket and the offset wheel; the structural features are that an outphase angle of the outphase counter weight of the tail part of the walking beam is adjustable and the offset wheel can not only swing along with the luffing of the walking beam, but also generate the self-rotation movement along with the swaying of the walking beam, which results in increased length of the stroke, increased liquid carrying capability and lowered energy consumption of liquid per ton.
Description
The utility model walking beam variable torque balance, take turns the extended-range oil pumper partially, be a kind of in oil exploitation the mechanical oil recovery oil pumper, especially can be used for conventional beam-pumping unit be transformed into the walking beam variable torque balance, wheel type oil pumping unit reaches and increases the journey purpose of energy saving partially.
At present, known conventional beam-pumping unit is constructed the four-bar motion structure of being made up of steel construction pieces such as horse head, walking beam, connecting rod, crank, reduction box, base, support, motors.The weight ratio of carrying and transferring on when oil pumping promotes and is carried out the motion of mechanism balance by the crank counterbalance in rotating generally all between 1.7～2.8 entirely when pumping operation.This has just caused energy consumption excessive.Existing existing technology is that the afterbody at conventional beam-pumping unit installs (out-phase) counterweight additional, thereby reaches purpose of energy saving.But because the various operating mode of non-adjustable very difficult adaptation at the out-phase angle of this kind out-phase walking beam balancing weight, individual other operating mode also may cause bigger energy consumption.
Oil development is during to the later stage, and crude oil water containing increases, reserves reduce, and is badly in need of strengthening liquid-extracting amount, cutting down the consumption of energy and solve the too high problem of cost of winning.And original mechanical equipment exists shortcomings such as the short liquid-extracting amount deficiency of stroke.
The utility model designs at the defective that " conventional beam-pumping unit " exists, and its objective is provides a kind of beam balance, takes turns the extended-range oil pumper partially.It not only can realize energy-conservation by the walking beam variable torque balance, and also available inclined to one side wheel travel prolongation mechanism realizes increasing stroke.
The utility model is achieved like this: at the front end dress ground of walking beam (a 11) rotating inclined to one side wheel (14), between upper end that adds high trestle (12) and inclined to one side wheel (14), install one pair of negative connecting rod (13) additional, install the counterweight (6) at an adjustable out-phase angle again at the afterbody of walking beam (11) additional.When walking beam swung up and down the suction crude oil of finishing overall process: wheel rotated with the pulling of negative connecting rod partially, the journey that heightens most can reach 60%, and be contained in the walking beam afterbody adjustable out-phase angle counterweight effectively balance the well head fluctuating load that changes, make the oil pumping function less have drive rotation under the energy consumption and realize energy-conservation.
Owing to adopted such scheme, can realize increasing journey, and afterbody adds adjustable out-phase counterweight and realizes that [ton liquid power consumption] is energy-conservation nearly 60%, simple in structure.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure diagram of the present utility model.
Among Fig. 11, motor; 2, belt; 3, reduction box; 4, crank; 5, add long connecting rod; 6, counterweight; 7, hanger; 8, crossbeam; 9, bearing pin; 10, locking bearing pin; 11, walking beam; 12, add high trestle; 13, negative connecting rod; 14, take turns partially; 15, wire rope; 16, polished rod eye; 17, base;
In Fig. 1, use belt (2) transmission between motor (1) and the reduction box (3), and the driven axle of reduction box (3) links to each other with crank (4), add high trestle (12) and interconnect the rotating bearing in place and connect and add long connecting rod (5) crossbeam (8) walking beam (11), front end at walking beam (11) is equipped with a rotary inclined to one side wheel (14), in adding on the base (17) one pair of negative connecting rod (13) is housed between the high trestle (12) and take turns (14) and frame partially, afterbody at walking beam (11) is equipped with the counterweight (6) that can adjust the out-phase angle, in order to guarantee the counterbalance effect of down-hole load variations amount, the general desirable scope in adjustable out-phase angle is 1～90 °.Hanger (7) connects with a bearing pin (9), and the locking bearing pin (10) that can adjust the out-phase angle is arranged in the upper end of hanger.When need transferring the out-phase angle, corresponding locking hole positioning and fixing bearing pin with the walking beam afterbody (9) locking gets final product after only needing counterweight hanger (7) adjusted to respective angles.
The utility model is adjusted earlier the out-phase offset angle of walking beam counterweight amount before use according to the well head load, hang up the well head load with the polished rod eye (16) of wire rope (15), and then starter motor rotates by belt transmission drive reduction box.And connecting-rod beam rotates to produce with crank and swings up and down, and wheel then produces rotation with the walking beam swing partially, and motion generation simultaneously swings up and down, and finishes the overall process that increases the journey reciprocal reciprocating oil pumping.
