The anti-escaped rope hanger is characterized in that the thrust bearing is arranged in the centre hole of the rope hanger; the thrust bearing seat is fixed on the rope hanger; the upper surface of the thrust bearing seat is provided with a concave platform; the center of the thrust bearing is inserted with the lock sleeve and passes through the rope hanger; the upper part of the lock sleeve is provided with a male screw matched with the lock cap to lock the lock sleeve and to press lock sleeve on the thrust bearing; a square clip is clamped on the upper part of the polished rod of which the lower part passes through the lock sleeve and is connected with a pumping rod via a well mouth, and the square clip is pressed on the lock sleeve; a thrust bearing is respectively arranged under symmetrical circular holes at both sides of the centre hole of the rope hanger; bearing seats are respectively fixed below the rope hanger; the centre of the thrust bearing is inserted with a lock sleeve and passes through the rope hanger; the lower part of the lock sleeve is provided with a male screw matched with the lock cap to limit the lock sleeve on the thrust bearing; one end of each hair plait is provided with a lead cap of which the outer diameter is greater than the inner diameter of the lock sleeve; the other end of each hair plait respectively passes through the lock sleeve, and is fixed on the suspension point of a mule head of a pumping machine.

Description

The anticreep polished rod eye
One, technical field
The utility model relates to and a kind ofly prevents that sucker rod disconnects or disconnected take off and a hair plait is beaten the anticreep polished rod eye of turning round.
Two, background technology
Oilfield pumping well is in the oil pumping machine oil pumping process at present, two hair plaits that hang polished rod eye are because the thick or pit shaft deflection of oil well oil, causing a mao plait to beat turns round, cause the deflection of the polished rod eye left and right sides, when polished rod eye rises, the load of polished rod all is pressed on the polished rod eye, the deflection of the polished rod eye left and right sides also causes the deflection of the polished rod left and right sides simultaneously, polished rod deflection also drives the left and right sides deflection thereupon of sucker rod tubing string, time has been grown and can cause that mao plait is disconnected and take off or pumping rod disengaging, cause the oil well maintenance that stops production, rate when influence the production of oil well causes very big inconvenience to the oil field production management.
Three, summary of the invention
The purpose of this utility model provides a kind of anticreep polished rod eye, solves the hair plait and beats the problem of taking off with pumping rod disengaging that twists off.
The technical solution of the utility model realizes in the following manner:
The utility model is by the rectangle polished rod eye, thrust shaft block, thrust bearing, lock sleeve, locking cap, the hair plait, polished rod and circular hole are formed, it is characterized in that at thrust bearing of polished rod eye centre bore top installation, thrust shaft block is fixed on the polished rod eye, be provided with concave station above the thrust shaft block, be inserted with a lock sleeve at the thrust bearing center, and pass polished rod eye, lock sleeve top is provided with male thread, lock lock sleeve with locking cap, and be pressed on the thrust bearing, polished rod top card top clamp, lock sleeve is passed in the bottom, be connected with sucker rod by well head, square clamp is pressed on the lock sleeve; Circular hole bottom in polished rod eye centre bore both sides symmetry, a thrust bearing is installed separately, bearing support is fixed on the bottom of polished rod eye separately, be inserted with a lock sleeve separately at the thrust bearing center, and pass polished rod eye, be provided with male thread in the lock sleeve bottom, cooperate lock sleeve spacing on thrust bearing with locking cap; Two hair plaits end are separately irritated plumbous cap are arranged, and its external diameter is greater than the lock sleeve internal diameter, and the other end of two hair plaits passes lock sleeve separately, is fixed on the suspension point of pumping unit horsehead.
Compared with the prior art the utility model has the following advantages:
1, the utility model is simple in structure, and is easy to install, can use any type.
2, prevent that mao plait from beating to twist off and take off that the pumping rod disengaging effect is remarkable.
3, alleviate oil recovery workman well-repairing work amount, reduced working strength of workers, saved workover cost.
