Abstract

The invention discloses a pulley oil pumping unit, comprising rope hanger, sling, donkey head, sneezing bar, bracket, balance weight, adjusting bolt, pulley block, driving roller, reducer and electric machine, where output end of the reducer is installed with a shaft coupling, which drives the driving roller, a driving rope is wound on the driving roller, and passes through a fixed pulley block at the bottom to a movable pulley block in the rear of the sneezing bar to the fixed pulley block and is finally fixed through rope clip onto a rotating shaft, the fixed pulley block is fixed through rotating shaft and bearing seat onto a base, and the movable pulley block is fixed at the rear end of the sneezing bar through rotating shaft and tail bearing. And it changes a crank-link rod mechanism into a driving rope to drive the pulley blocks, simplifying driving system and raising driving efficiency.

Description

Pulley type beam-pumping unit
Technical field the present invention relates to the oil pumper that a kind of oil exploitation is used.
Background technology is in the ground installation of oil exploitation, and oil pumper has obtained using widely, mainly contains conventional beam-pumping unit, two horse head oil pumper, belt oil pumping machine, hydraulic oil pumping unit and reducing gear oil pumper at present.Conventional beam-pumping unit, it is simple in structure, easy to manufacture, reliability is high, good endurance, easy to maintenance, but its counterbalance effect is poor, and the clean torque ripple of crank is big, has shortcomings such as negative torque, inefficiency and energy consumption are big; Two horse head oil pumpers, it is that walking beam postbrachium with conventional pumping unit manufactures the reducing circular shape, and adopts flexible the connection between walking beam postbrachium and the crossbeam.Have the long stroke characteristics, operate steadily, additional dynamic load is little, good balance effect.Price is more expensive relatively, and stroke is regulated inconvenient; Belt oil pumping machine, it carries protection system by transmission system, exchange system, suspension, mistake and back-up system is formed, and has that bearing load is big, pump efficiency is high, economize on electricity and an overall efficiency advantages of higher, but price is relatively costly, and maintenance is inconvenient.In relating to pulley type beam-pumping unit, the full balancing chain pulley gearing vertical oil pumper of Chinese patent (01211426) is by sprocket wheel, gipsy sheave transferring power; (91233273) pulley double-lift long stroke pumping unit, (92103513) crank pulley oil sucker are by crank connecting link and pulley transferring power; (02224640) hoisting pulley block balance oil extractor is to adopt hoisting pulley block to come balanced load moment; (87210524) pulley type beam-pumping unit increases stroke by crank connecting rod apparatus; (88208582) pulley type flexiblesystem oil pumper is non-walking beam structure.Above-mentioned patent does not all relate to driving drum and assembly pulley mechanism driving power.(02120836) curved beam-pumping unit that drives through assembly pulley is though it adopts fixed pulley and movable pulley transferring power, complex structure, cost height; (98217143) reel-type pumping unit though adopt cylinder mode transferring power, does not relate to beam-pumping unit.
Summary of the invention the objective of the invention is to design a kind of pulley type beam-pumping unit, and net torque is big to solve, the technical problem of inefficiency, inconvenient maintenance aspect.The present invention is achieved in that pulley type beam-pumping unit, and it comprises hanger, lifting rope, horse head, walking beam, support, balance weight, adjusting bolt, top sheave group, drives rope, downslide wheels, driving drum, reducer, assembly pulley support and motor etc.On the output shaft of reducer shaft coupling is installed, shaft coupling and driving drum link, and drive rope one end and are wrapped on the driving drum, the other end is walked around the fixed pulley group, walk around running block again, arrive the fixed pulley group again, and be fixed on by wire clips in the rotating shaft of fixed pulley group; At the walking beam rear portion tail bearing is housed, running block is installed in the rotating shaft, and this rotating shaft is fixed on the walking beam by tail bearing; The fixed pulley group is installed in the rotating shaft of bottom, and the two ends of this rotating shaft are fixed on the base by bearing support.In the walking beam upper rear end balance weight is installed also.Driving drum is made up of drum shaft, barrel, brake, is processed with the grooving of lay winding wire ropes simultaneously on barrel.The kind of drive of reducer output shaft and driving drum can be selected gear drive, chain drive or belt transmission as required.The present invention changes crank-link mechanism for driving rope drive pulley group, has simplified transmission system, has improved transmission efficiency.Assembly pulley can be selected different assembly pulley compound modes for use according to on-the-spot actual needs.Like this, required power of electric motor will reduce greatly, and the moment of torsion that reduction box transmits also obviously descends.The balance of oil pumper is regulated by the balance weight that is installed in the walking beam rear end, and balance weight can suitably be added and subtracted according to actual needs, and positions by regulating bolt.The stroke of oil pumper is regulated by regulating the length that drives rope between movable pulley and fixed pulley and is realized; The transmission that jig frequency is regulated by changing motor and reducer recently realizes.The present invention is simple in structure, easy to manufacture, overall efficiency is high, easy to maintenance.
Description of drawings Fig. 1 is a structural representation of the present invention, and 1 polished rod eye, 2 lifting ropes, 3 horse heads, 4 are regulated bolt, 5 balance weights, 6 walking beams, 7 running blocks, 8 driving ropes, 9 fixed pulley groups, 10 driving drums, 11 reducers, 12 motors, 13 supports among the figure.
The specific embodiment is with reference to accompanying drawing 1, and it comprises the present invention polished rod eye (1), lifting rope (2), horse head (3), adjusting bolt (4), balance weight (5), walking beam (6), running block (7), drives rope (8), fixed pulley group (9), driving drum (10), reducer (11), motor (12), support (13).Motor (12) is fixed on the base, motor (12) links by belt and reducer (11), on the output shaft of reducer (11) shaft coupling is installed, driving drum (10) links with shaft coupling, and driving drum is made up of drum shaft, barrel, brake, on barrel, be processed with grooving, drive rope one end and be wrapped on the barrel, the other end is walked around fixed pulley group (9), walks around running block (7) again, get back to fixed pulley group (9) again, and be fixed on by wire clips in the rotating shaft of fixed pulley group; Tail bearing is equipped with at the walking beam rear portion, and running block is installed in the rotating shaft, and this rotating shaft is fixed on the assembly pulley support on the walking beam by tail bearing; The fixed pulley group is installed in the rotating shaft of bottom, and the two ends of this rotating shaft are fixed on the base by bearing support, and running block and fixed pulley group are made up of 5 pulleys respectively.In the walking beam upper rear end balance weight (5) is installed also, regulates the rear end that bolt (4) is installed in walking beam, balance weight (5) positions by regulating bolt (4).The power drive reducer (11) of motor (12) like this, reducer (11) drives driving drum (10) by shaft coupling and rotates, drive rope (8) and go up winding or release alternately at driving drum (10), drive rope (8) and drive fixed pulley group (9) and running block (7) rotation respectively, when horse head (3) when being in propradation, drive the tail down campaign that rope spurs walking beam (6) this moment, driving when oil pumper is in down stroke restricts to discharge from driving drum (10) again launches.For the ladder that on oil pumper support (13), has been welded easy to maintenance.
