Abstract

The utility model relates to oil production equipment in the petroleum industry, in particular to a double-lead-hammer hanging rope of an oil pump unit for connecting the oil pumping unit and a wellhead polished rod in a mechanical production system. The technical scheme is as follows: the double-lead-hammer suspension rope comprises a fur plait, an upper square clamp, an upper rope hanger and an upper lead hammer; two sides of the upper rope hanger are connected by the fur plait; two lower ends of the fur plait are respectively connected with the upper lead hammer; and the lower ends of the upper rope hanger and the upper lead hammer are connected with a lower rope hanger and a lower lead hammer by the fur plait. The double-lead-hammer hanging rope has the benefits that after the polished rod is broken and drops, the spare rope hanger and the square clamp can prevent the polished rod from dropping into a mine shaft, and the oil well can continue normal production, thus effectively saving operating cost, reducing the loss of crude oil and improving the economic benefit.

Description

Oil pumper Ledate hammer suspension strop

One, technical field:

The utility model relates to a kind of petroleum industry oil production equipment, the oil pumper Ledate hammer suspension strop that oil pumper is connected with wellhead polish rod in particularly a kind of computer collecting system.

Two, background technology:

An existing hair plait has only a secondary plummet to connect the polished rod production of recovering the oil by square clamp, polished rod eye; polished rod produces stress and concentrates at square clamp place; disconnected taking off takes place in long-time use the easily; in case polished rod fracture; there are not second protection and carrying; often cause polished rod to fall well, blowout takes place, pollute, stop well, the underproduction, cost increase, go up problems such as operation.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, a kind of oil pumper Ledate hammer suspension strop is provided, the secondary safety guarantee can be provided, avoid accidents such as blowout, pollution, oil pump damage, well site safety, make oil well can continue ordinary production.

Its technical scheme is: comprise a mao plait, top clamp, go up polished rod eye and last plummet, the both sides of last polished rod eye connect by the hair plait, two lower ends of hair plait connect plummet respectively, and described lower end of going up polished rod eye and last plummet is connected polished rod eye and following plummet down by the hair plait.

The middle mounting spring of above-mentioned following polished rod eye, below clamp and following block teeth.

The utility model increases the single raise plummet, connect standby polished rod eye and square clamp, during normal operation under the oil pumper the square clamp in the plumb device under the effect of buffer spring, do not hang pumping unit system load, suspension loading stress point concentrates on clamp place, plummet suspension arrangement side.When the square in the above clamp of polished rod place is disconnected when taking off, because the effect of gravity, polished rod glides, standby side's clamp compression spring, and seat hangs up load on standby polished rod eye, prevents that polished rod from coming off in the pit shaft, avoided accidents such as blowout, pollution, oil pump damage, well site safety, oil well can continue ordinary production.

The beneficial effects of the utility model are: polished rod is disconnected take off after, standby polished rod eye and square clamp can prevent that polished rod from coming off in the pit shaft, and oil well can continue ordinary production, has effectively saved the expenditure of operating cost, and reduced the crude oil loss, improved economic benefit.

Four, description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Among the last figure: hair plait (1), polished rod (2), top clamp (3), go up polished rod eye (4), go up plummet (5), below clamp (6), spring (7), down polished rod eye (8), down plummet (9), go up block teeth (10), lower lock block (11).

Five, the specific embodiment:

In conjunction with the accompanying drawings 1, the utility model will be further described:

The utility model is mainly by hair plait 1, polished rod 2, top clamp 3, last polished rod eye 4, last plummet 5, below clamp 6, spring 7, following polished rod eye 8, following plummet 9, last block teeth 10, lower lock block 11 is formed, hair plait 1 from bottom to top successively connecting descend plummet 9 and following polished rod eye 8, the iron wire pin is put on following polished rod eye 8 both sides, above polished rod 2, spring 7 is placed on down above the polished rod eye 8 again, below clamp 6 is placed on above the spring 7, putting down block teeth 11 well tightens, last polished rod eye 4 is placed on above the plummet 5, the iron wire pin is put on last polished rod eye 4 both sides, top clamp 3 is placed on above the polished rod eye 4, and puts block teeth 10 well and tighten and get final product.

When the oil field pumping well ordinary production, polished rod 2 bears load and concentrates on polished rod eye 4, top clamp 3, after the long-time running, polished rod 2 since stress concentrate on when clamp 3 places, top are disconnected to be taken off, because the effect of gravity, polished rod 2 glides, below clamp 6 compression springs 7, thus seat hangs up load on following polished rod eye 8, prevent that polished rod 2 from coming off in the pit shaft, thereby realize that oil well continues the purpose of ordinary production.

Claims

1. an oil pumper Ledate is hammered suspension strop into shape, comprise a mao plait (1), top clamp (3), go up polished rod eye (4) and last plummet (5), the both sides of last polished rod eye (4) connect by hair plait (1), two lower ends of hair plait (1) connect plummet (5) respectively, it is characterized in that: described lower end of going up polished rod eye (4) and last plummet (5) is connected polished rod eye (8) and following plummet (9) down by hair plait (1).

2. oil pumper Ledate hammer suspension strop according to claim 1 is characterized in that: described middle mounting spring (7), below clamp (6) and the following block teeth (11) of polished rod eye (8) down.
