Abstract
The utility model relates to an oil sucker. The motor drives a crank installed on an output shaft of a speed reducer to rotate through the speed reducer. A pulley and a balancing block are installed on a curved bar. One end of a cable is fixed on the top of a tower. The cable firstly winds the pulley of the crank, and then winds the pulley installed on the top of the tower; finally, the cable is connected with a sucker rod. A counterpoise is also connected with the sucker rod after reversing by the pulley on the top of the tower through the cable. When the crank rotates, the pulley of the crank is a movable pulley and drives the cable to make the sucker rod do up and down reciprocating motion. The stroke of the sucker rod equals 4 times of the length of the crank. The oil sucker has long stroke, fine balancing effect, balanced torque, high efficiency and favorable energy saving effect.
Description
The utility model relates to a kind of pumping unit.
Existing pumping unit, the beam pumping unit stroke is short, and efficient is low, and speed reducer is a double output shaft, the structure heaviness; Chain type oil pump and other distance-increasing type pumping unit complex structures, manufacture difficulty is big, the price height.
The utility model is for a kind of new-type pumping unit is provided, its simple structure, and it is convenient to manufacture, and stroke is long, the efficient height, good balance effect, the moment of torsion equilibrium, running is steady, good energy-conserving effect.
The utility model is achieved in that new-type pumping unit adopts the gentle rope of crank new mechanism, and this mechanism is by crank, frame, gentle rope, pulley, load is formed, in the mechanism, crank is a driving link, and hinge joint is on the fulcrum on the frame, and an end of gentle rope is connected on the crank, behind the static pulley on the pile warp frame, the other end connects with load, when crank rotates, affects gentle rope and drives load and do straight reciprocating motion.
New-type pumping unit is by driving part, pylon, and wire rope and counterweight are formed.Driving part is rotated by the crank of speed reducer drive installation on reduction gearbox output shaft by motor, and an equilibrium block and a pulley are housed on the crank.Tower top is equipped with one group of pulley, and wire rope one end is fixed on tower top, the pulley on the first pile warp crank, and the pulley of pile warp tower top connects with the sucker rod polished rod after the commutation then.Counterweight, is also linked together with the sucker rod polished rod after the pulley commutation of tower top by wire rope.When crank rotated, the pulley on the crank drove the sucker rod polished rod by wire rope and pumps.
The utility model is described in further detail below in conjunction with accompanying drawing;
Accompanying drawing 1 is the gentle rope of crank structural scheme of mechanism;
Accompanying drawing 2 is a crank wire rope increment pumping unit organigram.
Among Fig. 1, (1) is crank, (2) be gentle rope, (3) be static pulley, (4) be frame, (5) are load, and gentle rope (2) one ends are connected on the crank (1), through being connected in the load (5) behind the static pulley (3), when rotating, crank (1) does reciprocating linear motion by gentle rope band dynamic load.
Among Fig. 2, (6) are motor, and (7) are speed reducer, and (8) are crank, (9) be pulley, (10) are equilibrium block, and (11) are wire rope, and (12) are the cat head pulleys, (13) be the sucker rod polished rod, (14) are the counterweight wire rope, and (15) are counterweights, and (16) are pylon.
Motor among Fig. 2 (6) drives speed reducer (7) through the transmission of one-level band, the crank (8) that drive is installed on speed reducer (7) output shaft rotates, the pulley (9) that is installed on the crank (8) is garden Zhou Yundong thereupon, pulley (9) then affects wire rope (11), and wire rope (11) is done through cat head pulley (12) drive sucker rod polished rod (13) and pumped.
Among Fig. 2, one end of wire rope (11) is fixed on the pylon top, pulley (9) on elder generation's pile warp crank (8), pile warp cat head pulley (12) drives sucker rod polished rod (13) more then, pulley (9) is equivalent to a movable pulley, there are increment effect, sucker rod stroke to equal 4 times of crank (8) length when therefore, crank rotates.
Among Fig. 2, counterweight (15) is suspended on the counterweight wire rope (14), and wire rope (14) pile warp cat head pulley (12) the back the other end is connected on the sucker rod polished rod (13), and counterweight (15) is easy to adjust, accurate, can reach the optimum balance effect, energy-saving effect is remarkable.
New-type pumping unit adopts single crank (8) to drive, and speed reducer (7) can be selected the standard speed reducer for use.
Equilibrium block (10) is installed on the crank (8), and balanced torsion reduces the motor Peak current better.
Claims (4)
1, a kind of crank wire rope increment pumping unit is characterized in that:
Adopted the gentle rope of crank mechanism, crank (8) is installed on the output shaft of speed reducer (7), connecting wire rope (11) on it, after wire rope (11) pile warp is fixed on the cat head pulley (12) on pylon (16) top, connect with sucker rod polished rod (13), crank (8) affects steel when rotating, silk rope (11) drives sucker rod polished rod (13) and pumps.
2, pumping unit according to claim 1, it is characterized in that upward installation one pulley (9) of crank (8), one end of wire rope (11) is fixed on the pylon top, elder generation's pile warp pulley (9), pile warp cat head pulley (12) again, connect with sucker rod polished rod (13) then, crank (8) is to connect wire rope (11) by pulley mounted thereto (9).
3, pumping unit according to claim 1 is characterized in that counterweight (15) is suspended on the counterweight wire rope (14), and behind this wire rope pile warp cat head pulley (12), the other end also connects with sucker rod polished rod (13).
4, pumping unit according to claim 1 is characterized in that above-mentioned crank (8) adopts single crank to drive.
