Abstract
The utility model relates to a kind of polished rod anticollision device, belongs to beam pumping unit oil recovery technique field in oil field machinery oil, particularly anti-polished rod collision pumping unit horsehead device.Be made up of polished rod positioning chuck, support bar, righting rod, adjustment jackscrew, support bar has center screw, its center screw internal thread is provided with adjustment jackscrew; In the both sides of the center screw of support bar, be symmetrically welded with horizontal vertical in the righting rod of support bar; Polished rod positioning chuck has symmetrical earhole, be inserted on righting rod by its earhole.The beneficial effects of the utility model both to have made polished rod placed in the middle, improves the accuracy rate that indicator card measures, and can prevent again polished rod from colliding pumping unit horsehead, improves stability and the service life of oil pumper operation.
Description
Technical field
The utility model relates to a kind of polished rod anticollision device, belongs to beam pumping unit oil recovery technique field in oil field machinery oil, particularly anti-polished rod collision pumping unit horsehead device.
Background technology
Beam pumping unit mechanical oil recovery is the mode that mining site generally adopts.Polished rod is the vitals that beam pumping unit is connected with pumpingh well.
In oil recovery process, polished rod is needed to drive sucker rod to be released by the oil of underground.Polished rod is connected to the upper end of rod string, and polished rod is connected with pumping unit horsehead by the polished rod eye on top, hair plait.Polished rod is positioned in the middle of mao plait.The load of the fluid column in oil well more than sucker rod and oil well pump born by polished rod, plays a part to transmit oil pumper power simultaneously.Polished rod is the part that in sucker rod, bearing load is maximum.
After polished rod eye hair plait suspended load, polished rod axis and two maos of plait axis co-planar, hair plait and horse head cambered surface tangent.By the restriction of polished rod, sucker rod length and lower-continuous mapping, the head of polished rod exceeds the longer length of square holding-down clip for finish rod (light is remaining) sometimes.Because the diameter of the diameter of thread protecting cap and polished rod is larger than the diameter of hair plait, so when polished rod and thread protecting cap move near mao plait and horse head cambered surface point of contact, polished rod or thread protecting cap can collide cambered plate, send ear-piercing sound, and the polished rod above square holding-down clip for finish rod is bent, only have when point of contact is more than thread protecting cap, polished rod could stretch again.The every round trip of such oil pumper, polished rod just bend and stretches once, and because oil pumper is continuous duty, for 5 times per minute, polished rod every day is bending stretches 7200 times, so the easy fatigue damage of polished rod, on square holding-down clip for finish rod, rupture in plane place.The polished rod broken must be changed, and to change on polished rod operation gesture than impact and produce and expense occurs, and to oil field, user brings loss.In addition, installing and using in process, due to oil pumper installation quality existing problems cause horse head to misalign, after oil field operation completion long more than the polished rod light reserve, the reason such as polished rod bends, cause the collision horse head that oil pumper polished rod in running is violent, have a strong impact on the service life of oil pumper and polished rod.
Utility model content
The problem of beam pumping unit polished rod collision horse head in running when the purpose of this utility model is to overcome mechanical oil recovery.There is provided one to increase work efficiency, ensure that rod-pumped well normally runs, produces, and a kind of polished rod anticollision device of handling safety.
The utility model is made up of polished rod positioning chuck, support bar, righting rod, adjustment jackscrew, and support bar has center screw, and its center screw internal thread is provided with adjustment jackscrew; In the both sides of the center screw of support bar, be symmetrically welded with horizontal vertical in the righting rod of support bar; Polished rod positioning chuck has symmetrical earhole, be inserted on righting rod by its earhole.
The beneficial effects of the utility model both to have made polished rod placed in the middle, improves the accuracy rate that indicator card measures, and can prevent again polished rod from colliding pumping unit horsehead, improves stability and the service life of oil pumper operation.
Accompanying drawing explanation
Fig. 1 is the utility model general structure principle schematic.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The utility model is made up of polished rod positioning chuck 1, support bar 8, righting rod 2, adjustment jackscrew 7, support bar 8 has center screw 9, and its center screw 9 internal thread is provided with adjustment jackscrew 7; In the both sides of the center screw of support bar 8, be symmetrically welded with horizontal vertical in the righting rod 2 of support bar 8; Polished rod positioning chuck 1 has symmetrical earhole 4, be inserted on righting rod 2 by its earhole 4.
The two ends of described support bar 8 are that semicircle holds up ring 6.
The middle part of described polished rod positioning chuck 1 is semi-annular shape structure, and both sides are symmetrical otic placode 5, otic placode 5 has symmetrical earhole 4, is inserted on righting rod 2 by its earhole 4.
The utility model is installed beam hanger for pumping machine top, semicircle hair plait 10 being placed in support bar 8 two ends is held up in ring 6, polished rod 3 is placed in the semi-annular shape at the middle part of polished rod positioning chuck 1, and make its center ofthe, rotate adjustment jackscrew 7, polish rod positioning chuck 1 slides on righting rod 2, namely the spacing between adjustable polished rod 3 and support bar 8, the light remaining part of polished rod 3 is divided produce certain intervals between pumping unit horsehead, thus avoid polished rod 3 and the generation of pumping unit horsehead collision phenomenon, improve stability and the service life of oil pumper operation.
