In order to provide an oil extraction equipment component which has the effects of centralizing, avoiding eccentric wear and tripping of an oil pumping rod, improving efficiency, reducing cost and improving the service performance of oil extraction equipment, the utility model is provided, which comprises a main body, a square clamp and a rotating mechanism; the rotating mechanism comprises a righting clamp body, a moving clamp body, a vertical shaft transmission pair, an intermittent transmission pair, a rocker arm and a connecting rod, wherein the vertical shaft transmission pair is assembled on the righting clamp body and the main body; the centralizing clamp body is provided with a central through hole corresponding to the sucker rod, and the top of the centralizing clamp body forms a chuck clamped on the sucker rod.
Description
The utility model belongs to the oil production equipment parts, rotates the rope hanger of sucker rod particularly a kind of automatic intermittence.
As shown in Figure 1 and Figure 2, the rope hanger of commonly using comprises the main body 2a that is provided with central through bore 21a and is installed in the insurance lock dog 3a and the square clamp 4a on main body 2a central through bore 21a top.Main body 2a both sides are provided with opening grooving 22a.Main body 2a is sheathed on the sucker rod 1a with central through bore 21a on it, and two wire rope 5a of pumping unit are connected in the opening grooving 22a of main body 2a both sides, and blocks sucker rod 1a by insurance lock dog 3a and square clamp 4a and hit outward.The rope hanger of this structure is the rope hanger of simple function, yet because the well location of the oil recovery well in oil field all has certain squareness usually, often causing slides places and produces between sucker rod 1a in the oil pipe and the oil pipe that eccentric wear is wiped or because of eccentric wear causes that sucker rod 1a wearing and tearing are pulled, the loosening back-off of screw thread, disconnected taking off and oil pipe wearing and tearing perforation, directly influence oil production and effective manufacture cycle, increase the well workover number of times, improve the expenditure of consumable material fund.A kind of oil pumping rod centering device is disclosed in recent years, but in use not only there is the deflection point that is difficult for finding accurately well location in it, change trouble, and increase oil-pumping resistance, life cycle is short, be not durable, can not fundamentally solve the eccentric wear between sucker rod and the oil pipe and sucker rod screw thread back-off gets loose and the disconnected problem of taking off.
The purpose of this utility model provides a kind of having concurrently and sets upright effect, avoids sucker rod partial wear to thread off, raise the efficiency, reduce cost, improve the rope hanger that rotates sucker rod automatic intermittence of oil production equipment usability.
The utility model comprises main body, square clamp and is mounted on the main body and drives the rotating machinery that sucker rod intermittently rotates; Main body is provided with central through bore, and both sides are provided with the opening grooving; Rotating machinery comprise be fixedly arranged on the sucker rod set upright the card body, be sheathed on sucker rod the card body that moves about, be mounted on the vertical shaft transmission set upright on card body and the main body, intermittently-driving is secondary and is mounted on intermittently-driving secondary and move about rocking arm and connecting rod between the card body; Set upright the card body and be provided with and the corresponding central through bore of sucker rod, the chuck that is clamped on the sucker rod is formed on its top.
Wherein:
Main center's through hole is the through hole of worm gear reaming; The one side is provided with worm hole vertical with the worm gear reaming and that connect; Set upright the card body towards having spline segment; Vertical transmission be comprise be fixedly arranged on the worm gear set upright on the card body and and with two ends be hubbed in the worm hole and with the worm and gear transmission of worm gear engaged worm; The intermittently-driving pair is to comprise that the ratchet that is fixedly arranged on worm screw one end reaches and the ratchet of ratchet engaged; The rocking arm middle part forms the depression that is provided with the pivot hole, and its two ends are respectively equipped with tie rod holes and axial ratchet holes; Rocking arm is hubbed at the worm screw extending end with its pivot hole; Ratchet elasticity is mounted in the axial ratchet holes of rocking arm, and with the ratchet ratchet engagement.
Be provided with the bearing reaming that group is established bearing between main center's through hole and the worm gear reaming; Set upright the bearing section that bearing is established for group in card body spline segment bottom; Set upright to organize between card body and the main body and be provided with thrust-bearing.
The worm screw two ends are hubbed in the worm hole of setting upright the card body by axle sleeve.
Set upright to organize between card body and the square clamp and be provided with thrust-bearing.
Set upright card body spline segment and be provided with the edge of a wing, location up; Main body end face group is provided with and is resisted against the positioning disk of setting upright on the edge of a wing, card body location.
Connecting rod comprises that an end is respectively equipped with the upper and lower bar of left and right hand thread section and the Adjusting bolt Adjusting screw of the upper and lower bar left and right hand thread section that is spirally connected.
Positioning disk with set upright the card body and the main body junction point is equiped with the O RunddichtringO.
Because the utility model comprises main body, square clamp and is mounted on the main body and drives the rotating machinery that sucker rod intermittently rotates; Main body is provided with central through bore, and both sides are provided with the opening grooving; Rotating machinery comprise be fixedly arranged on the sucker rod set upright the card body, be sheathed on sucker rod the card body that moves about, be mounted on the vertical shaft transmission set upright on card body and the main body, intermittently-driving is secondary and is mounted on intermittently-driving secondary and move about rocking arm and connecting rod between the card body; Set upright the card body and be provided with and the corresponding central through bore of sucker rod, the chuck that is clamped on the sucker rod is formed on its top.During the pumping unit operation, sucker rod is done the motion of upper and lower stroke on it; During the sucker rod down stroke, the sealer end face that is fixed on the sucker rod is resisted against the card body bottom surface of moving about, the card body that moves about is produced upwards contact active force, and rotate counterclockwise, drive the sucker rod rotation through intermittently-driving pair and vertical shaft transmission through connecting rod drive rocking arm.During the sucker rod up stroke, be fixed on the sealer end face on the sucker rod and the card body that moves about and break away from, rocking arm drives rocking arm and oppositely clockwise rotates, and make the intermittently-driving pair be reversed the backlash journey by the downward gravity of card body and connecting rod that moves about.So, in the pumping unit operation process, when the upper and lower to-and-fro motion of sucker rod, make sucker rod intermittently rotation automatically by the utility model, stopping to take place sucker rod releases and comes off and the phenomenon of eccentric wear, come off and expense expenditure that eccentric wear produces thereby reduced, reduce production costs, improved the oil effectively rate because of sucker rod releases.Not only have concurrently and set upright effect, avoid sucker rod partial wear to thread off, and raise the efficiency, reduce cost, improve the oil production equipment usability, thereby reach the purpose of this utility model.
