Abstract
A pumping rod roller erection device relates to a pumping rod roller eccentric wear prevention erection device which is connected between two pumping rods on the eccentric wear section, which comprises a main rod, rollers and a pin, wherein the rollers are evenly arranged on the orientation at which the main rod is axially protected at an angel of 45 degrees, the two ends of the main rod are both provided with wrench grooves used for rotating with the pumping rods and are respectively rotated with pumping rod couplings. The device can support guiding in eight directions, which can always prevent the pumping rods from contacting with the inner wall of oil pipes, and has reliable intensity, persistent abradability, enough noncorrosibility and excellent heat stability.
Description
Technical field
The utility model relates to a kind of rod-pumped well erection device with the supporting anti-eccentric wear of sucker rod, particularly a kind of sucker rod roller type erection device that connects between two sucker rods of eccentric wear section.
Background technology
At present, the sucker rod of rod-pumped well is that polished rod does not have erection device, and is especially very easily inclined to one side by mill for inclined shaft or lower curved section sucker rod, ground inclined to one side sucker rod and can only eliminate, and then strengthen cost of production.The industry of for this reason recovering the oil thirsts for having the sucker rod erection device to occur.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of sucker rod roller type erection device with reliable pull strength, lasting abrasion resistance, enough corrosion resistance and good heat stability is provided.
The purpose of this utility model is achieved in that by mobile jib, roller and bearing pin and constitutes, it is characterized in that: roller is arranged on the orientation that the mobile jib axis projection is 45 ° uniformly, two of mobile jib is equipped with and the spin spanner groove of usefulness of sucker rod, spins with rod collar respectively.
Described roller is set to four, and their cylindrical is the drum type arc, is arranged on uniformly in the groove on four orientation that the mobile jib axis projection is 45 °.
One of described mobile jib is an internal thread, and the other end is an external screw thread.
Described bearing pin and the stationary fit of mobile jib pin shaft hole, an end is immersed oneself in, and the other end and mobile jib are affixed.
Advantage of the present utility model is to have overcome the deficiencies in the prior art, and a kind of erection device is provided, and its mobile jib is short and thick, and reliable pull strength is arranged, and its axial tensile strength is 350KN, and radially maximum is held lotus 1.4KN, and be 10 fatigue life
7Inferior heat-resisting oscillation cycle.But this device is provided with all support guides of eight directions, can remain sucker rod and not contact with tube inner wall, has reliable intensity, lasting abrasion resistance, enough corrosion resistance and good heat stability.
The explanation of accompanying drawing drawing
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model roller structure schematic diagram.
The specific embodiment
The utility model is the erection device that connects between two sucker rods of eccentric wear section.Form by mobile jib 1, roller 2, bearing pin 3 three parts.As Fig. 1, Fig. 2, roller 2 of the present utility model is set to four their cylindricals and is the drum type arc, is arranged on uniformly in the groove on four orientation that mobile jib 1 axis projection is 45 °.One of the mobile jib of mobile jib 1 is an internal thread, and the other end is an external screw thread.Two is equipped with and the spin spanner groove 4 of usefulness of sucker rod, spins with rod collar respectively.The pin shaft hole stationary fit of described bearing pin 3 and mobile jib 1, an end is immersed oneself in, the other end and mobile jib firm welding.
The internal and external screw thread at two of mobile jib 1 of the present utility model screws with rod collar and is connected, rely on the mobile jib 1 four rolling 2 radially the axis projection of section intersect and to be eight directions of 45 °, roller 2 circular arc cylindricals and tube inner wall support guide, in sucker rod pumps, four rolling 2 support of in oil pipe, rolling, remain sucker rod and do not contact, guarantee that it is not by mill partially with tube inner wall.
Claims (3)
1, a kind of sucker rod roller type erection device, constitute by mobile jib, roller and bearing pin, it is characterized in that: roller is arranged on the orientation that the mobile jib axis projection is 45 ° uniformly, and two of mobile jib is equipped with and the spin spanner groove of usefulness of sucker rod, spins with rod collar respectively.
2, sucker rod roller type erection device according to claim 1, it is characterized in that: described roller is set to four, and their cylindrical is the drum type arc, is arranged on uniformly in the groove on four orientation that the mobile jib axis projection is 45 °.Sucker rod roller type erection device according to claim 1 is characterized in that: one of mobile jib is an internal thread, and the other end is an external screw thread.
