Abstract

An adjusting device for a beam hanger of an oil pumping machine comprises a polish rod clamp, a steel wire rope, a suspended plate, a steel wire rope fixing column and a polish rod. The steel wire rope fixing column is fixed at the lower end of the steel wire rope, two sections of the steel wire rope penetrate through the suspended plate symmetrically, the polish rod penetrates through the center of the suspended plate, the upper portion of the polish rod is clamped by the polish rod clamp, a torsion releasing bearing is sleeved at the lower portion of the steel wire rope, and the torsion releasing bearing is positioned between the suspended plate and the steel wire rope fixing column. The torsion releasing bearing can prevent the steel wire rope from twisting, so that the beam hanger cannot twist clockwise and anticlockwise repeatedly by force in running up and down, an oil pumping rod suspended on the beam hanger cannot twist to trip, production period of oil wells is long, production halt and well repair are eliminated, and economic benefits are obvious.

Description

Oil pumper polished rod eye adjusting device

Technical field

The utility model is the device on the oil-field oil pumper, particularly a kind of oil pumper polished rod eye adjusting device.

Background technology

The oil pumper polished rod eye is the device that connects oil pumping polish rod and oil pumper, and hairiness is distinguished son on the polished rod eye, and hair distinguishes that the son upper end hangs over waving on the horse head of oil pumper; So, require hair to distinguish that son has flexibility, because of a little; What hair was distinguished the son employing is wire rope, and the wire rope of many braided steel wire one-tenth has certain strength of turning round, and after stressed, will cause that the oil pumper polished rod eye reverses; Cause the positive repeatedly detorsion of polished rod simultaneously, cause the rod string dropout, cause oil well to stop production; The oil well production cycle is short, and the recovery well workover is frequent, and economic benefit is low.

Summary of the invention

The purpose of the utility model provides a kind of oil pumper polished rod eye adjusting device, prevents that the oil pumper polished rod eye from reversing, and avoids rod string to thread off, and prolongs the oil well production cycle, increases economic efficiency.

The purpose of the utility model is achieved in that and comprises polished rod clamp, wire rope, appending disk, wire rope fixed leg, polished rod composition; The wire rope fixed leg is fixed on the wire rope lower end; Two strand steel wire rope symmetries are passed appending disk, and polished rod passes in the middle of appending disk, and the polish rod clamp subcard is lived polished rod top; The torsion release bearing is sleeved on the wire rope bottom, the torsion release bearing be in appending disk and between the wire rope fixed leg.

The beneficial effect of the utility model is: the torsion release bearing can be abolished the strength of turning round on the wire rope; Polished rod eye moves up and down when stressed not can positive repeatedly detorsion; The rod string that is suspended on the polished rod eye can not reverse dropout, and the oil well production cycle is long, does not stop production; Not well workover has remarkable economic efficiency.

Description of drawings

Fig. 1 is the assembling drawing of the utility model embodiment.

The specific embodiment

Below in conjunction with Fig. 1 the utility model embodiment is described.

The embodiment of the utility model comprises polished rod clamp 1, wire rope 2, appending disk 3, torsion release bearing 4, wire rope fixed leg 5, polished rod 6 compositions; Wire rope 2 fixed legs 5 are fixed on wire rope 2 lower ends; Two strand steel wire ropes, 2 symmetries are passed appending disk 3, and polished rod 6 passes in the middle of appending disk 3, and polished rod clamp 1 blocks polished rod 6 tops; Torsion release bearing 4 is sleeved on wire rope 2 bottoms, torsion release bearing 4 be in appending disk 3 and between wire rope fixed leg 5.

Wire rope 2 is suspended on the oil pumper; Polished rod 6 bottoms are connected with rod string, and torsion release bearing 4 can be eliminated the strength of turning round on the wire rope 2, make the torsion on the wire rope 2 can not be delivered on the polished rod 6; The rod string that is connected polished rod 6 bottoms can not reverse, and can not thread off.

In order to adapt to retrofitting torsion release bearing 4 on the polished rod eye of having produced, can existing torsion release bearing be severed into two and put into, insert into the overcoat of slotting again and behind the wire rope it is entangled, make the torsion release bearing become as a whole.
