Description
Technical field
The utility model relates to oil-gas field development field, is specifically related to a kind of rod-taper whirligig.
Background technology
Along with China's major part oil field progresses into intermediary and later stages mining phase, the rod and tube partial-wear problem order benefit of rod pumped well is outstanding.From eccentric wear position, sucker rod shows as box cupling or body side is polished, and severe patient sucker rod screw thread is polished; Oil pipe shows as inwall and is ground with the groove that is parallel to axle center, is even worn through.Visible, the R a T that rod and tube partial-wear occurs is all more serious at side eccentric wear.The current existing device that can realize sucker rod rotary has sucker rod automatic intermittent circulator and rod-taper rope suspension apparatus.These two kinds of devices can realize the intermittent rotary of sucker rod, but, the power rotated relies on the active force between well head packing sealer end face and travelling card bottom surface to provide, when two faces come in contact time, a very large shock loading can be produced, cause oil pumping vibration of bar, very large impact is caused on the driving parts in device, decrease the life-span of driving parts, also may cause the generation of rod parting phenomenon.
Utility model content
The purpose of this utility model is to provide a kind of rod-taper whirligig, solved the multinomial defect of above-mentioned front fog lamp of automobile, the automatic intermittent achieving sucker rod rotates, and makes sucker rod 360 degree rotation, reach the object of sucker rod uniform wear, thus extend the life-span of sucker rod.
The technical problem that the utility model solves can realize by the following technical solutions: a kind of rod-taper whirligig, comprise housing, apparatus main body, hollow shaft and rotating mechanism, described housing is connected with apparatus main body, hollow shaft is arranged in housing, hollow shaft is connected with rotating mechanism, apparatus main body is provided with central through hole one, housing both sides are provided with opening grooving, hollow shaft is provided with central through hole two, described rotating mechanism comprises cam and ratchet, cam and ratchet are respectively equipped with central through hole three and central through hole four, cam top and cam bottom are all provided with deep groove ball bearing one, the top and bottom of cam are all provided with thrust ball bearing, described cam is provided with ratchet, ratchet is provided with ratchet, ratchet is connected with ratchet, the inner surface of ratchet is provided with keyway, described keyway is connected with hollow shaft by flat key, circlip for shaft is provided with between flat key and hollow shaft, the described hollow shaft upper end side of being provided with clamp, Fang Kazi is fixedly connected with sucker rod, hollow shaft top and hollow shaft bottom are all provided with deep groove ball bearing two, described thrust ball bearing lower end is provided with sleeve, sleeve lower end is provided with disc spring.
Preferably, described central through hole two, central through hole three, central through hole four all with central through hole one concentric.
Preferably, described housing side ratchet position is provided with baffle plate, and baffle plate is connected with housing by screw.
Preferably, described apparatus main body and housing tip junction are provided with O shape rubber seal.
Preferably, described hollow shaft Basolateral is provided with felt collar.
Preferably, described hollow shaft bottom is provided with round nut.
Employing the utility model has the advantage of: change rotary motion by this rod-taper whirligig into by moving both vertically that the elastic deformation of contained spring is caused, the automatic intermittent finally achieving sucker rod rotates, make sucker rod 360 degree rotation, reach sucker rod uniform wear; By the spring of indoor design, it can " increment of load compresses, and namely unloading recovers ", to make suffered by sucker rod shock loading reduce, thus extends the life-span of sucker rod; Do not need in this device outside install driving mechanism, avoid maintenance, keep in repair wellhead assembly time operator there is personal injury.In a word, what the use of this rod-taper whirligig can extend eccentric wear oil well is excused from a college course the phase, decreases the generation of rod parting phenomenon, and can not increase disadvantageous extra factor to prolongation pumpingh well pump detection period, have good application prospect.

Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of rod-taper whirligig, comprise housing 1, apparatus main body, hollow shaft 16 and rotating mechanism, described housing 1 is connected with apparatus main body, hollow shaft 16 is arranged in housing 1, hollow shaft 16 is connected with rotating mechanism, apparatus main body is provided with central through hole one, housing 1 both sides are provided with opening grooving 2, hollow shaft 16 is provided with central through hole two, described rotating mechanism comprises cam 7 and ratchet 9, cam 7 and ratchet 9 are respectively equipped with central through hole three and central through hole four, cam 7 top and cam 7 bottom are all provided with deep groove ball bearing 1, the top and bottom of cam 7 are all provided with thrust ball bearing 5, described cam 7 is provided with ratchet 17, ratchet 9 is provided with ratchet, ratchet 17 is connected with ratchet, the inner surface of ratchet 9 is provided with keyway, described keyway is connected with hollow shaft 16 by flat key 10, circlip for shaft is provided with between flat key 10 and hollow shaft 16, the described hollow shaft 16 upper end side of being provided with clamp, Fang Kazi is fixedly connected with sucker rod, hollow shaft 16 top and hollow shaft 16 bottom are all provided with deep groove ball bearing 26, described thrust ball bearing 5 lower end is provided with sleeve 12, sleeve 12 lower end is provided with disc spring 13, described central through hole two, central through hole three, central through hole four all with central through hole one concentric, ratchet 18 position, described housing 1 side is provided with baffle plate, baffle plate is connected with housing 1 by screw, described apparatus main body and junction, housing 1 top are provided with O shape rubber seal 3, described hollow shaft 16 Basolateral is provided with felt collar 14, described hollow shaft 16 bottom is provided with round nut 15.
According to the structure of rod-taper whirligig, oil pumper is when upstroke, spring-compressed causes the displacement on vertical direction, through cam 7 mechanism, the movement transition of vertical direction is become the rotary motion of cam 7, and key secondary through the intermittently-driving of ratchet 9 mechanism drives hollow shaft 16 to rotate again, and hollow shaft 16 drives sucker rod rotary by the frictional force between square clamp; When oil pumper carries out down stroke, amount of spring compression reduces the motion caused straight up, and through cam 7 mechanism, the motion of vertical direction is become the rotary motion of cam 7, now intermittently-driving pair is reversed backlash journey.Because spring-compressed absorbs energy, when load reduces time, spring can discharge again the energy of storage, therefore utilizes spring to absorb and releases energy, and the automatic intermittent that both can realize sucker rod rotates, and turn avoid the generation of shock loading simultaneously.
Because rod-taper whirligig itself has the function of beam hanger for pumping machine, so rod-taper whirligig can replace former polished rod eye completely, former polished rod eye need only be disassembled during installation, rod-taper whirligig is installed, simple, convenient.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model manual and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
