Abstract
The utility model discloses a pulley wheel type beam-pumping unit. It includes a rope hanger, a lifting rope, a horsehead, a walking beam, a bracket, a balance block, a regulating bolt, a pulley block, a driving pulley, a speed reducer and an electric machine, etc. A coupling which drives the driving roller is installed at the output terminal of the decelerator. The actuation cord wraps on the driving roller. The actuation cord bypasses the fixed pulley block on the bottom, and then bypasses the movable pulley block behind the walking beam, and finally reaches the fixed pulley block and is fixed on the shaft through a cable head. The fixed pulley block is fixed on the base through the shaft and the bearing seat; the movable pulley block is fixed at the back end of the walking beam through the shaft and the tail bearing. The utility model changes the crank link mechanism into the actuation rope actuation pulley block, simplifying the transmission system and boosting the transmission efficiency.
Description
Technical field the utility model relates to the pumping unit that a kind of petroleum production is used.
Background technique is in the ground installation of petroleum production, and pumping unit has obtained using widely, mainly contains conventional beam-pumping unit, two horse head pumping unit, belt oil pumping machine, hydraulic oil pumping unit and reducing gear pumping unit 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 pumping units, 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 protective system by transmission system, reversing mechanism, suspension system, 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 balance chain pulley gearing vertical pumping unit of Chinese patent (01211426) is by sprocket wheel, gipsy sheave transferring power; (91233273) pulley dbl act long stroke pumping unit, (92103513) crank pulley oil sucker are by crank-connecting rod 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 flexiblesystem pumping unit is non-walking beam structure.Above-mentioned patent does not all relate to driving drum and sheave block mechanism driving power.(02120836) curved beam-pumping unit that drives through sheave block is though it adopts static 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.
The summary of the invention the purpose of this utility model is a kind of pulley type beam-pumping unit of design, and net torque is big to solve, the technical problem of inefficiency, inconvenient maintenance aspect.The utility model is achieved in that pulley type beam-pumping unit, and it comprises hanger, lifting rope, horse head, walking beam, support, equilibrium block, adjusting bolt, top sheave group, drives rope, downslide wheels, driving drum, retarder, sheave block support and motor etc.On the output shaft of retarder coupling is installed, coupling and driving drum link, and drive rope one end and are wrapped on the driving drum, the other end is walked around the static pulley group, walk around running block again, arrive the static pulley group again, and be fixed on by wire clips in the rotating shaft of static 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 static 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 equilibrium block is installed also.Driving drum is made up of drum shaft, roller, brake, is processed with the grooving of lay winding wire ropes simultaneously on roller.The kind of drive of reducer output shaft and driving drum can be selected gear transmission, chain transmission or belt transmission as required.The utility model changes connecting rod for driving rope drive pulley group, has simplified transmission system, has improved transmission efficiency.Sheave block can be selected different sheave block compound modes for use according to on-the-spot actual demand.Like this, required power of electric motor will reduce greatly, and the moment of torsion that speed reducer transmits also obviously descends.The balance of pumping unit is regulated by the equilibrium block that is installed in the walking beam rear end, and equilibrium block can suitably be added and subtracted according to actual needs, and positions by regulating bolt.The stroke of pumping unit is regulated by regulating the length that drives rope between movable pulley and static pulley and is realized; The transmission that jig frequency is regulated by changing motor and retarder recently realizes.The utility model 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 utility model, and 1 rope hanger, 2 lifting ropes, 3 horse heads, 4 are regulated bolt, 5 equilibrium blocks, 6 walking beams, 7 running blocks, 8 driving ropes, 9 static pulley groups, 10 driving drums, 11 retarders, 12 motors, 13 supports among the figure.
Embodiment is with reference to accompanying drawing 1, and it comprises the utility model rope hanger (1), lifting rope (2), horse head (3), adjusting bolt (4), equilibrium block (5), walking beam (6), running block (7), drives rope (8), static pulley group (9), driving drum (10), retarder (11), motor (12), support (13).Motor (12) is fixed on the base, motor (12) links by belt and retarder (11), on the output shaft of retarder (11) coupling is installed, driving drum (10) links with coupling, and driving drum is made up of drum shaft, roller, brake, on roller, be processed with grooving, drive rope one end and be wrapped on the roller, the other end is walked around static pulley group (9), walks around running block (7) again, get back to static pulley group (9) again, and be fixed on by wire clips in the rotating shaft of static 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 sheave block support on the walking beam by tail bearing; The static 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 static pulley group are made up of 5 pulleys respectively.In the walking beam upper rear end equilibrium block (5) is installed also, regulates the rear end that bolt (4) is installed in walking beam, equilibrium block (5) positions by regulating bolt (4).The motivational drive retarder (11) of motor (12) like this, retarder (11) drives driving drum (10) by coupling and rotates, drive rope (8) and go up winding or release alternately at driving drum (10), drive rope (8) and drive static 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 pumping unit is in down stroke restricts to discharge from driving drum (10) again launches.For the ladder that on pumping unit support (13), has been welded easy to maintenance.
