Abstract

The utility model relates to a novel balancer of a beam-balanced oil pumping unit, which comprises a hinge shaft (1), a guide beam (2), a balancing weight (3), a guide screw (4), a plane thrust bearing (5), a hand wheel (6), a tether column (7), a pulley (8), a cable wire (9) and a wire hook (10), and is characterized in that the guide beam (2) is hung on the tail portion of a walking beam of the oil pumping unit through the hinge shaft (1), the balancing weight (3) is sleeved on the guide beam (2), the guide screw (4) is screwed in nuts which are arranged in the guide beam (2), the plane thrust bearing (5) is sleeved on steps which are arranged on the rear portion of the guide screw (4), the tail portion of the guide screw (4) is equipped with the hand wheel (6), the front portion of the balancing weight (3) is equipped with the tether column (7), the front portion of the guide beam (2) is equipped with the pulley (8), and the wire hook (10) is arranged on a bottom base of the oil pumping unit. When trimming moment is adjusted, the balancing weight (3) can upwards and downwards move along the guide beam (2) through artificially rotating the hand wheel (6) and also through using the cable wire (9) by means of the self power of oil pumping unit.

Description

The novel equalizer of beam-balanced pumping unit

One, technical field

The novel equalizer of the beam-balanced pumping unit that the utility model is related belongs to a vitals of the beam-balanced pumping unit that petroleum industry machinery oil production uses.

Two, background technology

Oil pumper is one of capital equipment of petroleum industry suction crude oil, and what our times various countries ground machine oil production equipment commonly used adopted more than 80 percent is the beam-pumping unit of crank balance.Each elephant progressively is transformed into the beam-pumping unit of crank balance the oil pumper (Fig. 3) of beam balance in recent years.Industrial practice proves: the oil pumper of beam balance on average economizes on electricity 20～25% than crank balanced pumping unit.The method of the beam-pumping unit adjustment moment of crank balance is to rely on to move the balance weight that is added on the crank, and the method for the oil pumper adjustment moment of beam balance is with the artificial adjustment piece of adding and subtracting on the equalizer of walking beam afterbody, remove because choose, the adjustment piece can not be done too greatly, though so little adjustment piece is moved easily, but can not be antitheft, easily lose, for standing on the ground, the guarantor adjustment piece can be added on the equalizer simultaneously, equalizer distance overhead can not be too high, but equalizer is overhead too near, pounds easily during running and hurts sb.'s feelings, and is very dangerous.For antitheft pressing for is difficult for stolen several tons the balance weight of weighing with little balance weight instead, should guarantee also that for safety balance weight is away from ground in the oil pumper operation process simultaneously.But weigh several tons balance weight when needs adjustment moment, make it move but quite difficulty along walking beam, therefore designing a kind of balance weight that can make just becomes the task of top priority along the light mobile mechanism of walking beam.

Three, summary of the invention

The purpose of this utility model provides a kind of novel equalizer of beam-balanced pumping unit, and this novel equalizer is made up of hinge axis, guide beam, balance weight, leading screw, plain thrust bearing, handwheel, bolt rope post, pulley, wire rope and rope hook.Wherein guide beam is suspended on the afterbody of oil pumper walking beam with hinge axis, balance weight is enclosed within on the guide beam, leading screw is screwed in the interior nut of guide beam, plain thrust bearing is enclosed within on the step at leading screw rear portion, afterbody at leading screw is equipped with handwheel, bolt rope post is housed in the front portion of balance weight, pulley is housed, individual rope hook is arranged on the base of oil pumper in the front portion of guide beam.When trimming moment is too little can not make oil pumper be in equilibrium state the time, the handwheel of rotational lead screw afterbody, balance weight glides at action of gravity lower edge guide beam, and trimming moment is strengthened; When trimming moment is too big, the backward rotation handwheel, balance weight along moving on the guide beam, reduces trimming moment under the dragging of leading screw; When the weight of balance weight too big, when the handwheel of rotational lead screw afterbody is had any problem, the wire rope of fastening on the rope post can be hung on the rope hook through pulley, the crawl oil pumper, the walking beam afterbody will move upward, and the distance between pulley and the rope hook becomes big, pulley and fasten that distance diminishes between the rope hook, thereby make balance weight along moving on the guide beam, trimming moment diminishes.Saved the adjustment piece on the equalizer, equalizer can design away from ground, has avoided in the oil pumper operation process equalizer to pound the accident of hurting sb.'s feelings.

Four, description of drawings

Be made up of hinge axis (1), guide beam (2), balance weight (3), leading screw (4), plain thrust bearing (5), handwheel (6), bolt rope post (7), pulley (8), wire rope (9) and rope hook (10), B is a walking beam among the figure, and C is a base.

Fig. 2 is the partial enlarged drawing of Fig. 1, and 3 is balance weight among the figure, and 4 is leading screw, and 5 is plain thrust bearing, and 6 is handwheel.

Fig. 3 is the outline drawing that the beam-balanced pumping unit of old-fashioned equalizer is housed.

A is the adjustment piece among the figure.

Five, the specific embodiment

Further describe utility model embodiment below with reference to the accompanying drawings, form by hinge axis (1), guide beam (2), balance weight (3), leading screw (4), plain thrust bearing (5), handwheel (6), bolt rope post (7), pulley (8), wire rope (9) and rope hook (10) referring to the novel equalizer of Fig. 1, beam-balanced pumping unit.Wherein guide beam (2) is suspended on the afterbody of oil pumper walking beam with hinge axis (1), balance weight (3) is enclosed within on the guide beam (2), leading screw (4) is screwed in the interior nut of guide beam (2), plain thrust bearing (5) is enclosed within on the step at leading screw (4) rear portion, afterbody at leading screw (4) is equipped with handwheel (6), in the front portion of balance weight (3) bolt rope post (7) is housed, pulley (8) is housed, rope hook (10) is arranged on oil pumping unit base in the front portion of guide beam (2).When the trimming moment of oil pumper too hour, rotate handwheel (6) and make leading screw overhanging, balance weight (3) glides at deadweight effect lower edge guide beam (2), makes the trimming moment of oil pumper become big; When the trimming moment of oil pumper is excessive, backward rotation handwheel (6), balance weight (3) drags on the lower edge guide beam (2) at leading screw (4) and moves, and trimming moment is diminished; When making, moves on the balance weight at need by the too big rotation handwheel of weight of balance weight, available wire rope (9) links together bolt rope post (7) and rope hook (10) through pulley (8), at this moment crawl oil pumper, the walking beam afterbody will move upward, distance between pulley (8) and rope hook (10) becomes big, the distance of bolt rope post (7) and pulley (8) diminishes, thereby drive balance weight (3) along moving on the guide beam (2), the trimming moment of oil pumper is diminished, after oil pumper is in equilibrium state, rotate handwheel (6) leading screw (4) is shunk in guide beam (2), balance weight (3) is fixed on the desired position.

The novel equalizer of beam-balanced pumping unit of the present utility model, it is improvement to beam-balanced pumping unit, rotating handwheel just can make balance weight move up and down along guide beam, reach the purpose of adjustment moment, when the weight of balance weight too big, when the rotation handwheel is had any problem, also can utilize the power of oil pumper itself to come adjustment moment, saved the adjustment piece that is added in the stolen easily management of inconvenience again on the equalizer, need not on equalizer, add and subtract the adjustment piece, equalizer is programmable away from ground, has avoided the accident that equalizer is hurted sb.'s feelings in the oil pumper operation process.
