Abstract
The utility model relates to a novel walking beam balance oil pumping unit mainly composed of a motor (1), belt drive (2), a speed reducer (3), a crank (4), a frame (5), a horse head (6), a suspending string (7), a walking beam (9), a connecting rod (10), a fixed balancing weight (12), a crane adjusting balancing weight (13), a manual moving adjusting balancing weight (14), a swivel mount (18) and a cantilever girder (19). When installing the unit above an oil well, people install the crane adjusting balancing weight (13) in sufficient quantity on the fixed balancing weight (12) and the cantilever girder (19) with a hoisting apparatus according to various well depths. When an oil well works normally, people only need to add or subtract manual moving adjusting balancing weights to the pumping unit at any time according to well conditions, the swivel mount (18) can adjust the height at which people add or subtract manual moving adjusting balancing weights to the pumping unit, and the manual moving adjusting balancing weights are stored at the tail end of a base of the frame. The novel walking beam balance pumping unit with low energy consumption is convenient to adjust, further reduces potential safety hazard because moving parts are arranged inside machine members, and keeps in effective balance condition due to walking beam balance.
Description
One, technical field
The novel beam-balanced pumping unit that the utility model relates to belongs to a kind of ground installation that petroleum industry machinery oil production is used.
Two, background technology
Oil pumper is one of capital equipment of petroleum industry suction crude oil, 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, and 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: beam-balanced pumping unit is than the beam-pumping unit of the crank balance 20-25% that on average economizes on electricity.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 to adjust balance weight with artificial the plus-minus on the equalizer of walking beam afterbody, adjust balance weight for the ease of personnel selection plus-minus on equalizer, equalizer must be near ground, equalizer was easily pounded and is hurted sb.'s feelings when the result caused the oil pumper running, very dangerous, nor be convenient to management, therefore design a kind of both being convenient to and adjust balance weight with artificial plus-minus, the beam-balanced pumping unit of being convenient to safety management again just becomes the task of top priority.
Three, summary of the invention
The purpose of this utility model provides a kind of novel beam-balanced pumping unit.This machine is by motor, band transmission, reductor, crank, frame, horse head, lifting rope, sucker rod, walking beam, connecting rod, inclined beams, fixed balance weight, car are hung Adjustable Balance Weight, people and are removed and adjust balance weight, swivel mount, semi girder, people and remove and adjust balance weight storage magazine, brake and support bar and form.Wherein the walking beam top that is installed in support is connected with hinge with support, front end at walking beam is equipped with the horse head that hangs the sucker rod lifting rope, inclined beams is equipped with in the rear end, fixed balance weight is welded on the afterbody of inclined beams, respectively stretch out a semi girder at the two ends of fixed balance weight, be used to hang car and hang adjustable smoothing heavily, respectively stretch out an otic placode in the both sides of fixed balance weight afterbody, swivel mount is housed on otic placode, be provided with a beam between swivel mount two otic placodes, be used to hang the people and remove the adjustment balance weight, swivel mount can change the artificial height that the people removes the adjustment balance weight of adding and subtracting on oil pumper, the supernumerary removes and adjusts people that balance weight leaves the frame bottom in and remove and adjust in the balance weight depots, on the output shaft of reductor, crank is housed, with connecting rod that crank and walking beam is hinged, when motor drives the reductor rotation through being with transmission, crank drives the walking beam reciprocally swinging through connecting rod, thereby driving sucker rod and balance weight rises repeatedly and descends, sucker rod back and forth rises and descends and reaches the purpose of aspirating crude oil from oil well, fixed balance weight, car hangs Adjustable Balance Weight and people and removes and adjust balance weight and back and forth rise and descend and be used to offset the load of sucker rod, brake is used for guaranteeing that walking beam is parked in the optional position that when the maintenance oil pumper support bar is used for locking walking beam when changing connecting rod and reductor.
The direct balanced oil extractor of novel beam can not only make oil pumper realize the balance of balance-type type; and can make the work of oil pumper adjustment balance become more convenient and easy; make and transfer ginseng work to make a practice of; when cutting down the consumption of energy; can also prolong machine, bar, the life-span of pump; movement parts has been eliminated potential safety hazard in frame.
