Description
Technical field:
The utility model relates to a kind of blue elephant that recovers the oil in the oil field that is used for, and particularly is a kind of tower ball-screw oil pumper.
Background technology:
At present, in the oil field machinery oil manufacturing process, oil pumper commonly used mainly contains two classes, i.e. beam-pumping unit and blue elephant, and beam-pumping unit is simple in structure, be widely used, but its spin balancing piece inertia is big, and is difficult for adjusting; Though blue elephant has advantages such as good balance effect and easy realization long stroke, but above-mentioned oil pumper is all relatively heavier, manufacturing and mounting hardness are also bigger, because motor speed height, must slow down through reductor, cause that drive path is long, drive disk assembly is many, transmission efficiency is low, so complete machine fault rate height, maintenance workload are big; " the standpipe type ball-screw oil pumper " patent No. of having invented: 02155444.7, though compact conformation, the sealing of wire rope and well head is a difficult problem, split type permanent-magnet synchronous core motor manufacture difficulty is big.
Summary of the invention:
The purpose of this utility model designs a kind of tower ball-screw oil pumper at above-mentioned weak point exactly.
Above-mentioned purpose is realized by following technical proposals:
The utility model comprises the polished rod joint, ball-screw, lower support, pillar, falsework, follower, the V-belt, driving wheel, motor, upper support, wire rope, pylon, guardrail, crown sheave, balance weight, steel cable termina, ladder, its integral body is pyramidal structure, pylon is cuboid tripod structure, the top is the double flute crown sheave, around the crown sheave is guardrail, be provided with ladder from the pylon side bottom to guardrail, there is upright the motor of installing in pylon central authorities, driving wheel is housed on the motor, ball-screw passes from the follower center, follower links into an integrated entity by falsework and pylon, between follower and the falsework bearing is housed, driving wheel is connected by the V-belt with follower, the ball-screw lower end is provided with the polished rod joint, pin, upper end are polished rod eyes, connect ball-screw under the polished rod eye, on connect wire rope, wire rope is by the crown sheave balance weight of ining succession.
Ball-screw in the above-mentioned tower ball-screw oil pumper is equipped with pillar up and down, connects by upper support and lower support between pillar and the pylon, and the pillar bottom is provided with the pin groove, so that pin moves up and down.
According to the tower ball-screw oil pumper that such scheme is made, motor drives the ball-screw rotating by the V-belt, and ball-screw adjutant rotation motion is the reciprocating decelerating effect that plays simultaneously, drive path is short, drive disk assembly is few, and is simple in structure, makes and installs than being easier to, easy to operate, the complete machine fault rate is low, long service life, transmission efficiency height, saves energy improves system efficiency of pumping well.
Description of drawings:
The utility model structural representation.
In the accompanying drawing, 1-polished rod, 2-polished rod joint, 3-ball-screw, the 4-lower support, 5-pillar, 6-falsework, 7-follower, the 8-V-belt, 9-driving wheel, 10-motor, the 11-upper support, 12-wire rope, 13-pylon, the 14-guardrail, 15-crown sheave, 16-balance weight, the 17-polished rod eye, 18-ladder, 19-pin.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
The utility model comprises polished rod joint 2, ball-screw 3, lower support 4, pillar 5, falsework 6, follower 7, V-belt 8, driving wheel 9, motor 10, upper support 11, wire rope 12, pylon 13, guardrail 14, crown sheave 15, balance weight 16, polished rod eye 17, ladder 18, pin 19, its integral body is pyramidal structure, pylon 13 is cuboid tripod structure, the top is a double flute crown sheave 15, around the crown sheave 15 is guardrail 14, be provided with ladder 18 from pylon 13 side bottom to guardrail 14, there is vertically installed motor 10 in pylon 13 central authorities, driving wheel 9 is housed on the motor 10, ball-screw 3 passes from follower 7 centers, follower 7 links into an integrated entity by falsework 6 and pylon 13, between follower 7 and the falsework 6 bearing is housed, driving wheel 9 is connected by V-belt 8 with follower 7, ball-screw 3 lower ends are provided with polished rod joint 2, pin 19, the polished rod joint connects polished rod 2 times, sucker rod, deep well pump, ball-screw 3 upper ends are polished rod eyes 17,17 times companies of polished rod eye ball-screw 3, on connect wire rope 12, wire rope 12 is by crown sheave 15 balance weight 16 of ining succession.
During the utility model work, motor 10 is forward and reverse rotation under the control of control system, and the power of output drives the 3 forward and reverse rotations of follower 7 drive ball-screws by V-belt 8 and pumps, and then drives deep well pump realization oil pumping.The time of control motor 10 forward and reverse rotations can be controlled the stroke and the jig frequency of oil pumper, can also adjust the jig frequency of oil pumper, to adapt to different well ' s conditions by changing driving wheel 9.Because wire rope 12 links to each other with balance weight 16, adjust balance weight 16 and equate with the gravity of sucker rod, can alleviate the rotary load of motor 10, obtain the optimum balance effect, improve the force-bearing situation of oil pumper.
