Abstract
A twist-preventing rope hanger for an oil pumping unit, a down-hole load suspension device for an oil pumping unit, overcomes the defects in the prior art. The twist-preventing rope hanger is so structured that a belleille spring is arranged on the upper part of the main body of the twist-preventing rope hanger, a slotted twist-preventing bearing is fixedly arranged in a plait plummet groove, a rope hanging baffle and the main body of the twist-preventing rope hanger are penetrated by a bolt in thread connection and fixed into a rope hanging baffle groove, an automatic adjusting jack screw is in thread connection with the rope hanging baffle, a pin is in thread connection with the main body of the twist-preventing rope hanger, and the main body of the twist-preventing rope hanger is connected with a polished rod through a square clamp. The twist-preventing rope hanger, being safe, green and well operated, is capable of damping when the twist-preventing rope hanger is loaded, automatically preventing plait twisting, and automatically adjusting the position of a polished rod. Moreover the twist-preventing rope hanger is longer in service lifetime, comprehensive in operation technology, specific in technical field, high in safety factor. And, the twist-preventing rope hanger is semi-automatic and becomes simpler and safer to operate after the structure is modified.
Description
One, technical field: the utility model relates to a kind of oil pumper and hangs the anti-polished rod eye of turning round of down-hole load device, especially oil pumper.
Two, background technology: the oil pumper in each oil field hangs the device of down-hole at present, in running, because well wellbore complex structure, add the unreasonable structure of old-fashioned polished rod eye, an appearance hair plait is beaten and is turned round the other horse head of polished rod when eating load, sprain and twist off polished rod, accident takes place to damage tester or hurt sb.'s feelings etc., is seriously influencing the normal operation of equipment and carrying out of every work
Three, summary of the invention: the purpose of this utility model provides the anti-polished rod eye of turning round of the high oil pumper of a kind of safety factor, it has overcome the shortcoming that other technology exists, the purpose of this utility model is to realize like this, it is to be turned round bearing, plummet, square clamp and polished rod and be formed by connecting by main body, disk spring, hair plait, baffle plate groove, pin, anti-beating, and disk spring places to be prevented turning round in the top of polished rod eye main body; Fluting is anti-beat turn round bearing place in mao plait plummet groove be fix dead; Polished rod eye baffle plate and polished rod eye main body penetrate screw thread with bolt and are fixed in the polished rod eye baffle plate groove; Automatically regulate jackscrew and the screwed connection of polished rod eye baffle plate; Pin and the screwed connection of polished rod eye main body; Prevent that turning round the polished rod eye main body is connected with polished rod by square clamp.
Meaning of the present utility model is: the utility model has been compared innovation with original polished rod eye: operational excellence, safety and environmental protection.The one, anti-turning round has shock-absorbing function when polished rod eye carries; The 2nd, the anti-polished rod eye of turning round can prevent automatically that mao plait from beating and turns round; The 3rd, prevent turning round the function that polished rod eye can be regulated position of polished rod automatically; Four are to use ILS; The 5th, operating technology is supporting comprehensive, strongly professional; The 6th, the safety factor height.Reached semi-automation from performance, the adjustment of structure makes the safe and simple of operation change.
Four, description of drawings: Fig. 1 is the anti-structural representation of turning round polished rod eye of oil pumper, among the figure 1, main body; 2, disk spring; 3, hair plait; 4, baffle plate groove; 5, pin; 6, anti-beating turned round bearing; 7, plummet; 8, square clamp; 9, polished rod.
Five, the specific embodiment: in Fig. 1, disk spring 2 places anti-turning round in the top of polished rod eye main body 1; Fluting is anti-beat turn round bearing 6 place in mao plait 3 plummets 7 grooves be fix dead; Polished rod eye baffle plate and polished rod eye main body 1 usefulness bolt penetrate screw thread and are fixed in the polished rod eye baffle plate groove 4; Automatically regulate jackscrew and the screwed connection of polished rod eye baffle plate; Pin 5 and 1 screwed connection of polished rod eye main body; Prevent that turning round polished rod eye main body 1 is connected with polished rod 9 by square clamp 8.
