Description
Technical field
The utility model relates to a kind of broadband oil pumper, particularly a kind of crank differential type broadband oil pumper.
Background technology
At present, China's oil-field thick-oil well, deeply take out in the Development Practice of well, mainly taking sucker rod pump production system as main.Supporting equipment is mainly taking the beam-pumping unit of large model and blue elephant as main with it.
But, the problem that current large model beam pumping unit ubiquity energy consumption is large, efficiency is low, running cost is higher and volume is larger, and be difficult to realize heavy crude producing and deeply take out desired long stroke, low jig frequency, can not meet the needs of thickened oil recovery.Therefore, develop a kind of oil pumper that meets thickened oil recovery requirement significant.
Utility model content
It is less that the utility model is intended to overcome existing oil pumper stroke, and the defect that running cost is high provides a kind of device that relies on crank differential motion to increase stroke.Its technical scheme adopting is as follows:
Crank differential type broadband oil pumper, comprise cylinder, broadband, guide wheel, support, wire rope, increase journey frame, increase journey fixed pulley, ballast box, polished rod eye, increase journey movable pulley, increase journey movable pulley frame, angle pulley, seesaw frame, back and forth slide block, power driven sprocket, back and forth connecting rod, back and forth crank, power chain, power drive sprocket, reduction box, motor, mounting base, cylinder is arranged on a top of the trellis, described broadband connects ballast box and polished rod eye by cylinder, described guide wheel is arranged on a top of the trellis, described wire rope connects the guide wheel in sleeve mechanism, increase journey fixed pulley, polished rod eye, increase journey movable pulley, angle pulley, and one end is connected on seesaw frame, described increasing journey frame is arranged on mounting base, and installation increases journey fixed pulley thereon, increase journey movable pulley, increase journey movable pulley frame.By the assembly pulley that increases journey frame, increasing journey fixed pulley, increasing journey movable pulley, the combination of increasing journey movable pulley frame, the large stroke that reciprocator produces before is further increased, and by wire rope, the large stroke reciprocating motion of generation is passed to the motion of polished rod eye drive sucker rod.
Described seesaw frame is arranged on mounting base, and reciprocal slide block, power driven sprocket, back and forth connecting rod, reciprocal crank be installed thereon, described reciprocal crank is coaxially connected with power driven sprocket, and drive reciprocal slide block by reciprocal connecting rod, described power drive sprocket is arranged on reduction box, and driving power driven sprocket by power chain, described motor is arranged on mounting base, and is connected on reduction box.Motor passes to power drive sprocket, power chain, power driven sprocket, reciprocal crank by reduction box by the slow-speed of revolution, back and forth crank drives reciprocal connecting rod, thereby reciprocal slide block is produced to be moved back and forth, because of the reciprocal crank of power drive sprocket driving both sides, and back and forth crank is oppositely installed, so back and forth slide block produces reverse sliding motion, produce differential effect, thereby increase stroke, and drive wire rope reverse shuffle by the angle pulley being arranged on reciprocal slide block, further strengthen stroke.
The utlity model has following advantage: due to the differential motion of angle pulley and the increasing Cheng Zuoyong of assembly pulley, make to adopt small organization to produce the reciprocating motion of large stroke, and the requirement of motor performance is reduced, thereby reduce the cost of producing, using, safeguard.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, crank differential type broadband oil pumper, comprises cylinder 1, broadband 2, guide wheel 3, support 4, wire rope 5, increase journey frame 6, increase journey fixed pulley 7, ballast box 8, polished rod eye 9, increase journey movable pulley 10, increase journey movable pulley frame 11, angle pulley 12, seesaw frame 13, back and forth slide block 14, power driven sprocket 15, back and forth connecting rod 16, back and forth crank 17, power chain 18, power drive sprocket 19, reduction box 20, motor 21, mounting base 22, described cylinder 1 is arranged on support 4 tops, and described broadband 2 connects ballast box 8 and polished rod eye 9 by cylinder 1, and described guide wheel 3 is arranged on support 4 tops, and described wire rope 5 connects the guide wheel 3 in sleeve mechanism, increase journey fixed pulley 7, polished rod eye 9, increase journey movable pulley 10, angle pulley 12, and one end is connected on seesaw frame 13, described increasing journey frame 6 is arranged on mounting base 22, and installs thereon and increase journey fixed pulley 7, increase journey movable pulley 10, increase journey movable pulley frame 11, described seesaw frame 13 is arranged on mounting base 22, and reciprocal slide block 14 is installed thereon, power driven sprocket 15, back and forth connecting rod 16, back and forth crank 17, described reciprocal crank 17 is coaxially connected with power driven sprocket 15, and drive reciprocal slide block 14 by reciprocal connecting rod 16, described power drive sprocket 19 is arranged on reduction box 20, and drive power driven sprocket 15 by power chain 18, described motor 21 is arranged on mounting base 22, and is connected on reduction box 20.
Motor 21 drives the interior mechanism of reduction box 20 to slow down, the slow-speed of revolution is passed to power drive sprocket 19 by reduction box 20 afterwards, power drive sprocket 19 drives power driven sprocket 15 by power chain 18, thereby drive power driven sprocket 15 and reciprocal crank 17 to rotate, back and forth crank 17 drives reciprocal connecting rod 16, thereby reciprocal slide block 14 is produced to be moved back and forth, because power drive sprocket 19 drives the reciprocal crank 17 of both sides, and back and forth crank 17 is oppositely installed, so back and forth slide block 14 produces reverse sliding motion, produce differential effect, thereby increase stroke, and drive wire rope 5 reverse shuffle by the angle pulley 12 being arranged on reciprocal slide block 14, further strengthen stroke, in addition, by increasing journey frame 6, increase journey fixed pulley 7, increase journey movable pulley 10, the assembly pulley that increasing journey movable pulley frame 11 combines further increases the large stroke that reciprocator produces before, and by wire rope 5, the large stroke producing is moved back and forth and passes to polished rod eye 9 and drive sucker rod motion.
