The specific embodiment
Embodiment 1
Contrast Fig. 1, Fig. 2, Fig. 3, the utility model device mainly is made up of circulator housing 1, disk spring 6, piston 7, reducer 8, overrunning clutch 9, square Kato 5.Two hair plaits 2 connect housing 1 respectively, and the utility model device is lifted on the horse head 36 of oil pumper by hair plait 2.Oil well pole 3 clamping side's clamps 4 are on square clamp 4 side's of being bearing in Katos 5.Be provided with cylindrical chute hole 19 in the housing 1, the front end of piston 7 slips in this chute hole 19.Pistons in the chute hole 19 are equipped with disk spring 67 times, the rear end of piston 7 be connected reduction case 20 below, both are connected as a single entity by bolt,, move up and down along chute hole 19 together under the elastic force effect of gravity and disk spring 6 at oil well pole 3.
Reducer 8 is worm type of reduction gearings, and its output---worm gear 12 and square Kato 5 are connected by bolt, and the two coaxial line rotates.Side's Kato 5 extends up to the outside of reduction case 20, is connected and sealed by sealing ring 22 in its junction with reduction case 20, does not trickle out to guarantee reducer 8 interior lubrication oil.
Piston 7 lower ends are plugged in the chute hole 19 on the housing 1, can slide up and down along chute hole 19, and chute hole 19 is built-in with disk spring 6, and every pair of disk spring 6 is symmetrical layers vertically and stacks, and the disk spring 6 of the superiors touches the front end of piston 7.
The input of reducer 8---worm screw 11, its symmetrical two ends are separately installed with overrunning clutch 9, and with worm screw 11 coaxial rotation.
Contrast Fig. 4, Fig. 5, overrunning clutch 9 is mainly by axle sleeve 27, one-way shaft core 28, fore-set 31, spring 30, roller 29, ball 37, gland 39 and fork 10 are formed, one-way shaft core 28 is installed on the worm screw 11, one end of fork 10 is provided with axle sleeve 27, axle sleeve 27 is socketed on the one-way shaft core 28, upwards be evenly equipped with several teeth groove 38 week of one-way shaft core 28, each teeth groove is made up of sagittal plane 40 and tangential face 41, on sagittal plane 40, be provided with hole 42, the hole is built-in with spring 30 and fore-set 31, the free end of spring 30 connects fore-set 31, and fore-set 31 pressures are touched on the inwall of axle sleeve 27, and fore-set 31 can slide in hole 42.The resistance of motion when rotating in order to reduce overrunning clutch 9 engagements is as far as possible established annular groove 43 respectively on the both ends of the surface of one-way shaft core 28, groove is built-in with ball 37, and adds a cover gland 39 in a side of axle sleeve 27.When axle sleeve 27 rotates counterclockwise, roller 29 is pressed to spring 30 by fore-set 31, make roller 29 towards teeth groove 38 gradually cross direction move, axle sleeve 27 can rotate relative to one-way shaft core 28, otherwise, make roller 29 when axle sleeve 27 clockwise directions rotate when the gradually narrow direction of teeth groove 38 moves, axle sleeve 27 drives one-way shaft core 28 by roller 29 and rotates together.
Fork 10 can face upward or downward, and present embodiment fork 10 is connected with housing 1 down.Fork 10 is provided with gathering sill 16, the directive wheel 26 that the corresponding position of housing 1 is provided with, directive wheel 26 places gathering sill 16 and can slide along this groove, because of the line of centres and the vertical direction of directive wheel 26 and one-way shaft core 28 has an angle, when the gathering sill on the fork 10 16 slided along directive wheel 26, fork 10 was the oscillation center swing with the center of one-way shaft core 28, and drive one-way shaft core 28 and worm screw 11 are rotated when swinging clockwise, when counter-clockwise swing, rotate relative to one-way shaft core 28.
As the oil pumper worker, when making horse head 36 upstrokes, oil well pole 3 bears fluid column gravity, on square clamp 4 side's of acting on Katos 5, again through worm gear 12, thrust bearing 15, central axis 21, deceleration box 20 is affacted on the disk spring 6 by piston 7, make it to be compressed, piston 7 moves down along chute hole 19, the reducer 8 that is attached thereto also moves down thereupon, the overrunning clutch 9 that is installed in the decelerator worm two ends is in the process of moving down, fork 10 wherein slides along directive wheel 26 by gathering sill 16 on it on the one hand, rotate around one-way shaft core 28 centers on the one hand, fork 10 drives the overrunning clutch 9 that is engaged with and rotates in rotation, because of overrunning clutch 9 is installed on the worm screw 11, and the rotation of one-way shaft core 28, make reducer 8 work, its output worm gear 12 rotates thereupon, and the square Kato 5 that is connected on the worm gear 12 rotates, and then the oil well pole 3 on the side's of being connected clamp 4 also rotates thereupon.Because of the speed reducing ratio of worm type of reduction gearing is generally all bigger, the speed reducing ratio of present embodiment reducer 8 is 1: 46, and the stroke per minute of the horse head 36 of oil pumper has 6 times.So the rotation of oil well pole 3 is quite slow, one week of axial rotation about 5 hours.When pumping unit horsehead 36 transfers down stroke to by upstroke, oil well pole 3 is because of the load sudden change, lay down fluid column load in a flash, the power that acts on the disk spring 6 disappears, disk spring 6 upwards resets, move on the promotion piston 7 and make fork 10 motions, fork 10 resets under the effect of spring 6, for following one-stroke rotation is got ready.And so forth, reached the purpose that makes oil well pole 3 slow rotation of automatic axial in oil well.
Present embodiment and the foregoing description are basic identical, only are the bar portion structure differences of fork, and the bar portion of fork is connected with reducer 20 up, sees also Fig. 6, Fig. 7, Fig. 8.
Bar portion one end of fork is connected with guide rod 33 by guide pin bushing 32, and guide rod 33 is socketed in the guide pin bushing 32, and the link position of fork and guide rod can be adjusted, and adjusts the back and with screw guide pin bushing 32 is fixed on the guide rod 33.One end of guide rod connects vertical with it push rod 35, the hinged roller 34 of the front end of push rod.The reduction case upside connects limiting plate 17, and limiting plate 17 is used for carrying out spacing to it when fork 10 rotates.Torsion spring 18 is socketed on the torsion spring pin 45 of limiting plate 17, and the one end is fixed on the limiting plate 17, and the other end is connected on the fork 10.Horse head upwards swing promotion roller moves push rod drive guide rod, and guide rod drives fork and rotates, when horse head does not act on the roller, and the rotation of torsion spring drive fork return, the fork rotation drives worm screw and one-way shaft core mounted thereto rotates.
When the oil pumper upstroke, horse head 36 upwards swing touches roller 34, upwards promotes roller 34, makes push rod 35 drive guide rod 33 motions, and fork 10 is swung to the right.The same reason, the swing of fork 10 make reducer 8 work, and the output worm gear 12 of its reducer 8 rotates thereupon, and then drive oil well pole 3 slowly rotates.When pumping unit horsehead 36 transfers down stroke to by upstroke, horse head 36 left, oil well pole 3 moves downwards, horse head 36 breaks away from fork 10.Simultaneously, fork 10 is reset to the position of limiting plate 17 under the effect of torsion spring 18, for following one-stroke rotation is got ready.Make oil well pole 3 rotations and so forth, general 5 hours one weeks of left-right rotation.
So, when oil pumper was worked, the utility model can make oil well pole do slowly to rotate the eccentric wear of oil well pole in oil well, can slowly rotate the whole circumference face that this eccentric wear is evenly arrived oil well pole by oil well pole, improved the application life of oil well pole greatly.Simultaneously, disk spring of the present utility model can absorb or slow down the impact load that acts on the oil well pole, alleviates the vibration of oil well pole.When circulator of the present utility model slowly rotates clockwise at the drive oil well pole, can offset because of the untimely internal stress that forms of loading transfer response becoming flexible adjacent two oil well pole connection of thread formation, effectively prevent coming off of oil well pole, make oil pumper work safety and reliability.
