Description
Affiliated technical field
The utility model relates to the special-purpose downhole tool of a kind of pumpingh well, especially relates to a kind of pumping rod connecting device.
Background technology
Sucker rod is that the power of oil pumper and motion are passed to the parts that oil well pump aspirates.Sucker rod is the elongate rod that is coupled together by box cupling successively by tens of to hundreds of sucker rods.In the oil pumping course of work, because roofbolt bears asymmetric repeat load, when driving sucker rod and move back and forth, because stroke magnitude of load and direction change and cause vibration up and down as: pumping unit horsehead, bring added impact load to sucker rod, cause the sucker rod connecting thread to get loose; Because hole deviation makes oil pipe center line and the sucker rod gravity direction in the oil well inconsistent, rod string is subjected to the additional torque effect in variable motion process up and down reciprocatingly, the direction of moment of torsion changes along with the variation of the rod string direction of motion, has formed the moment of torsion that unscrews to the rod string screw thread; Because the vibration that rod sag, speed change cause forms shock loading, causes additional torque, the moment of torsion that unscrews that is created on the rod string is strengthened, cause the loosening of connecting thread so that thread off.
At present, the connection of sucker rod adopts the box cupling screw thread that sucker rod is connected in series usually, also there is the multi-form sucker rod anti-dropping device of employing to connect, as disclosed Chinese utility model patent on June 2nd, 2004 " sucker rod damping anti-dropping device " (CN2619044Y), disclosed Chinese utility model patent on July 27th, 2005 " sucker rod anti-dropping device " (CN2713199Y), above-mentioned 2 technical schemes all have certain pumping rod disengaging function that prevents, but exist complex structure, difficulty of processing big, be not easy to deficiencies such as The field and anticreep effect instability.
The utility model content
For overcome existing sucker rod connect in the linkage complex structure, the difficulty of processing that exist big, be not easy to deficiencies such as The field and anticreep effect instability, the utility model provides a kind of pumping rod connecting device.This apparatus structure is simple, can effectively prevent sucker rod the get loose generation of phenomenon of connecting thread in the course of the work.
The technical scheme that its technical problem that solves the utility model pumping rod connecting device adopts: comprising sucker rod, adapter sleeve, fixedlys connected with adapter sleeve in sucker rod main body upper end, and there is keyway the upper end of sucker rod main body; There are the boss rank sucker rod body of rod lower end, and key is arranged at the bottom on boss rank; On the sucker rod body of rod fixed cover is housed, is fixed with the screw thread that is connected with adapter sleeve.The sucker rod main body is fixedly connected sequentially from top to bottom and is formed by top connection I, the sucker rod body of rod, anti-bull stick.Internal thread one end of adapter sleeve is connected with the sucker rod main body, and the other end is connected with fixed cover on the sucker rod that is connected; The key of anti-bull stick lower end inserts in the keyway of the sucker rod main body upper end that is connected.
Another technical scheme that its technical problem that solves the utility model pumping rod connecting device adopts: main body is a dumb-bell shape, is the body of rod between the top connection II on top and the boss rank of bottom, and the lower end on body of rod lower boss rank is a key, and fixed cover is housed on the body of rod; The key of body of rod bottom is installed in the keyway of lower contact upper end; One end of adapter sleeve is fixedlyed connected with fixed cover, and the other end is fixedlyed connected with lower contact.Main body is composed of a fixed connection by top connection II and anti-bull stick.
The beneficial effects of the utility model are that simple and reasonable, attachment security is reliable, and is easy to operate.
