Description
One, technical field
The novel beam-balanced pumping unit that the present invention 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, and unnecessary balance weight also is not easy to management, therefore design a kind of plus-minus adjustment balance weight on equalizer of need not choosing, the novel beam-balanced pumping unit that just can adjust the trimming moment of oil pumper easily just becomes the task of top priority.
Three, summary of the invention
The purpose of this invention is to provide a kind of novel beam-balanced pumping unit.This machine is made up of motor, band transmission, reductor, crank, support, horse head, lifting rope, sucker rod, walking beam, connecting rod, balance weight, stretch, handle, brake and support bar.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 sucker rod and lifting rope, rear end and balance weight are articulated and connected, one end and the balance weight of stretch are hinged, the other end is hinged with walking beam again, and thread rotary orientation opposite screw rod in two is housed at the middle part of stretch, utilizes the handle rotating screw bolt that stretch is elongated or shortened, swing forward or backward thereby drive balance weight, to reach the purpose of adjusting trimming moment.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, balance weight back and forth rises and descends and is 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.In order to make the oil recovery worker just can rotate stretching pole with handle on ground, but handle has made a kind of double-swing ratchet spanner, the people stands on the ground swing handle just can make stretch rotate, and swings forward or backward thereby drive balance weight, reaches the purpose of adjusting balance.
Novel beam-balanced pumping unit can not only make oil pumper realize the balance of balance-type type; and can make the work of adjusting balance of well pumping unit become more convenient and easy; realized accent ginseng work regular practice; because balance of well pumping unit is good; when cutting down the consumption of energy, can also prolong machine, bar; in the life-span of pump, movement parts has been eliminated potential safety hazard away from ground.

Fig. 1 is the structure principle chart of novel beam-balanced pumping unit.
Fig. 2 is the structure principle chart of handle.
Fig. 3 is the structure chart of old-fashioned beam-balanced pumping unit.
Five, the specific embodiment
Further describe the embodiment of the invention below with reference to the accompanying drawings, referring to Fig. 1, novel beam-balanced pumping unit is by motor (1), band transmission (2), reductor (3), crank (4), support (5), horse head (6), lifting rope (7), sucker rod (8), walking beam (9), connecting rod (10), balance weight (11), stretch (12), brake (13). support bar (14) and handle (15) are formed, wherein walking beam (9) top that is installed in support (5) is connected with support (5) hinge, the horse head (6) of the lifting rope (7) that hangs sucker rod (8) is housed at the front end of walking beam (9), rear end and balance weight (11) are hinged, one end of stretch (12) and balance weight (11) are hinged, the other end is hinged with walking beam (9) again, be manufactured with a screw rod that two thread rotary orientation is opposite at the middle part of stretch (12), external part in screw rod (12) bottom is equipped with handle (15), utilize handle (15) rotating screw bolt that stretch (12) is elongated or shortened, balance weight (11) is swung forward or backward, thereby reach the purpose of adjusting trimming moment.Crank (4) is housed on the output shaft of reductor (3), hinged with connecting rod (10) crank (4) and walking beam (9), when motor (1) drives reductor (3) rotation through being with transmission (2), crank (4) will drive walking beam (9) reciprocally swinging through connecting rod (10), drive horse head (6) again respectively during walking beam (9) reciprocally swinging and balance weight (11) is up and down reciprocatingly swung, sucker rod (8) is suspended on the horse head (6) with lifting rope (7), sucker rod (8) back and forth rises and descends and reaches from oil well the purpose of suction crude oil, balance weight (11) back and forth rises and descends and is used to offset the load of sucker rod, brake (13) is used for guaranteeing that oil pumper is parked in the optional position that when the maintenance oil pumper support bar (14) is used for when changing connecting rod (10) or reductor (3) walking beam being locked in the position of needs.
The structural principle that has the handle of bidirectional swinging ratchet spanner function in the technical scheme of the present invention is realized by Fig. 2, handle (15) is by wheel disc (15-1), rotating shaft (15-2). finger (15-3), handlebar (15-4) and connecting pin (15-5) are formed, wheel disc (15-1) is installed in the lower end of the screw rod of stretch (12) among the figure (1), rotating shaft (15-2) is installed in the endoporus of wheel disc (15-1), can relatively rotate, the front end of rotating shaft (15-2) is inserted in the groove of handlebar (15-4), and link together with connecting pin (15-5) with handlebar (15-4), five equilibrium is fixed with and is no less than six fingers (15-3) on the garden week of wheel disc (15-1), stirs finger (15-3) with handlebar (15-4) screw rod of wheel disc (15-1) and stretch (12) is rotated.For preventing that swing from appearring in handlebar (15-4) in the oil pumper operation process, the front end of handle bar (15-4) makes the crotch shape at certain inclination angle, and the head of crotch withstood on the surface of wheel disc inflexibly in oil pumper turns round.
Novel beam-balanced pumping unit of the present invention is the improvement to old-fashioned beam-balanced pumping unit; as long as the oil recovery worker stands in the screw rod rotation that makes stretch (12) middle part on the base of oil pumper with handle (15); stretch (12) will elongate or shorten; balance weight is swung forward or backward; thereby finished the adjusting work of trimming moment; also walking beam can be swung to certain angle in case of necessity; balance weight under dragging, gravity is moved down; make the operation of swing handle lighter; saved the little balance weight that necessary personnel selection can be moved in the balance weight of this machine; reduced the managerial trouble of unnecessary little balance weight; balance weight can be away from ground; reduced potential safety hazard, this machine adopts beam balance, good balance effect; because balancing is convenient; balancing work is made a practice of, greatly reduced the energy consumption of oil pumping, and can increase oil production and prolongation machine by transferring ginseng; bar; the application life of pump.
