Abstract

The utility model discloses an anti-twisting device for a beam hanger. The anti-twisting device comprises a square clamp, two suspension ropes, a suspension disc, suspension rope fixing bases and a polish rod, wherein the two suspension ropes penetrate through the lower end of the suspension disc and are respectively provided with a suspension rope fixing base, so as to suspend the suspension disc on the suspension ropes; the upper ends of the suspension ropes are suspended on a pumping unit; the square clamp is arranged on the suspension disc; the polish rod penetrates through the middle of the suspension disc and the square clamp; the polish rod is clamped by the square clamp, so that the polish rod and the pumping unit are integrally connected; an anti-twisting clamp is arranged between the two suspension ropes; the anti-twisting clamp is arranged above the square clamp. After the anti-twisting clamp is arranged between the two suspension ropes, the twisting force of the suspension ropes is fixed inside the device, the polish rod does not repeatedly twist positively and negatively when being operated and stressed vertically, and a rod string connected below the polish rod is not twisted so as to be tripped, so that an oil well is long in production period, and great economic benefits are achieved.

Description

The anti-deflection device of turning round of polished rod eye

Technical field

The utility model is the device on oil-field oil pumper, is the anti-deflection device of turning round of a kind of polished rod eye.

Background technology

Beam hanger for pumping machine is the device that connects oil pumping polish rod and oil pumper, has outstanding rope on polished rod eye, and outstanding rope upper end hangs over waving on horse head of oil pumper, require outstanding rope to have flexibility, so what outstanding rope adopted is wire rope, the wire rope of many braided steel wire one-tenth has certain strength of turning round, after stressed, will cause that beam hanger for pumping machine reverses, cause polished rod positive detorsion repeatedly simultaneously, cause rod string dropout, cause oil well to stop production, the oil well production cycle is short, and recovery well workover is frequent, and economic benefit is low.

Summary of the invention

The purpose of this utility model is to provide a kind of polished rod eye prevents turning round deflection device, prevents that beam hanger for pumping machine from reversing, deflection, avoids rod string to thread off, and extends the oil well production cycle, increases economic efficiency.

The purpose of this utility model is achieved in that the side's of comprising clamp, outstanding rope, appending disk, outstanding rope holder, polished rod, two outstanding ropes are respectively installed an outstanding rope holder through appending disk posterior end, appending disk is suspended on rope, the upper end of outstanding rope is suspended on oil pumper, and square clamp seat is on appending disk, and polished rod passes in the middle of appending disk, square clamp, Fang Kazi blocks polished rod, polished rod and oil pumper are linked into an integrated entity, between two outstanding ropes, the anti-card of turning round is installed, prevent turning round card on square clamp.

The beneficial effects of the utility model are: between two outstanding ropes, anti-turning round after card is installed, the strength of turning round of outstanding rope is fixed in device, and polished rod moves not positive detorsion repeatedly when stressed up and down, and the rod string being connected under polished rod can not reverse dropout, the oil well production cycle is long, has significant economic benefit.

Accompanying drawing is the assembling drawing of the utility model embodiment.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model embodiment is described.

As seen from the figure, embodiment of the present utility model comprises the anti-card 1 of turning round, Fang Kazi 2, outstanding rope 3, appending disk 4, outstanding rope holder 5, polished rod 6, two outstanding ropes 3 are respectively installed an outstanding rope holder 5 through appending disk 4 posterior ends, appending disk 4 is suspended on rope 3, the upper end of outstanding rope 3 is suspended on oil pumper, 2 of Fang Kazi are on appending disk 4, polished rod 6 is from appending disk 4, in the middle of Fang Kazi 2, pass, Fang Kazi 2 blocks polished rod 6, polished rod 6 and oil pumper are linked into an integrated entity, between two outstanding ropes 3, the anti-card 1 of turning round is installed, the anti-two ends of turning round card 1 are separately fixed on two outstanding ropes 3, prevent turning round card 1 on square clamp 2, the not mounting or dismounting of the side's of impact clamp 2 and oil well test.
