Abstract
The utility model discloses a beam hanger centralizing positioner comprising a polish rod centralizing card which can be slidably covered on the polish rod and two hair plait lead sinker locator cards which are respectively fixed on the lateral sides of the polish rod centralizing card and are chucked on the lead sinker. The utility model has the function of centralizing and positioning the knotting hair plait and the distorting beam hanger and can prevent pumping rod tripping, hair plait cutting off, the polish rod stretching and has stronger practicability. The utility model has reasonable design, simple structure, strong placement, small volume and is convenient to process and install.
Description
(1) technical field
The utility model relates to a kind of locator of setting upright that is used for rod-pumped well polished rod eye and hair plait.
(2) background technology
It is the important accessory that polished rod eye and hair plait are in state of a control when guaranteeing the oil pumper ordinary production that polished rod eye is set upright locator.At present, the two horse head oil pumper hair plaits that use are sub-thread hair plait, two ends produce revolving force in the same way under stretching state, cause polished rod eye to rotate to direction of rotation, and hair plait itself is beaten and is turned round, cause operation to drive a well and hang the load difficulty, operating time reaches 2-4 hour, cause the pumping rod disengaging well of lying simultaneously, annual this type of oil pumper causes oil pumper to be threaded off, and to take way be with the fixing polished rod eye of vertical rod in about 2% economic loss units up to a million because of polished rod eye rotates, under running status, be suitable for extension load but inapplicable operation drives a well.
(3) summary of the invention
The utility model purpose provides a kind of polished rod eye and sets upright locator, is used for the rod-pumped well polished rod eye is set upright the location, with solution pumping rod disengaging, the broken burst of disconnected problem that reaches the stretch bending polished rod in hair plait end.
In order to solve the problems of the technologies described above, the utility model comprises that polished rod sets upright card and two hair plait plummet locator cards, polished rod is set upright card and slidably is enclosed within on the polished rod, and two hair plait plummet locator cards are separately fixed at the both sides that polished rod is set upright card, and hair plait plummet locator card is clamped on the plummet.
It is two valve structures that described polished rod is set upright card, on this two lobe concavo-convex positioning step is arranged, and this two lobe connects by bolt.
Described hair plait plummet locator card is two valve structures, and this two lobe connects by bolt.
Described polished rod is set upright between card and the hair plait plummet locator card and is connected with connecting rod, and two maos of plait plummet locator cards are set upright axis line symmetry with respect to polished rod.
The beneficial effects of the utility model are: the utility model is beaten the hair plait and is turned round, crooked the playing of polished rod eye set upright positioning action, prevents pumping rod disengaging, disconnected hair plait, stretch bending polished rod, and stronger practicality is arranged; Reasonable in design, simple in structure, with strong points; Volume is little, processing, easy for installation.
