Abstract
The invention discloses the wear-resisting oil drill rocker of length in a kind of service life, including: drilling rod body, described drilling rod body is provided with mounting groove, in described mounting groove, briquetting and trim ring are provided with bearing inner race, it is evenly arranged with some spring grooves in the inner side of described bearing inner race, radially it is provided with the spring cooperated with it in described spring groove, the inner side of described spring offsets with drilling rod body, the outside of described spring offsets with bearing inner race, rotated by rotor in the outside of described bearing inner race and be provided with bearing outer ring, the outside of described bearing outer ring is provided with wearing layer.Advantage is: when removing drilling rod in horizontal well, inclined shaft and service shaft; if shock casing wall; bearing inner race with spring can stress shrink automatically; can effective bumper and absorbing shock; it is easy to remove, protects drilling rod, wearing layer after bearing outer ring stress, can be driven simultaneously to move along bearing inner race not stall under the effect of rotor; abrasion resistant effect is good, and drilling life of drill pipe is long.
Description
Technical field
The present invention relates to a kind of drilling well, power drill for well workover tool.
Background technology
Petroleum resources are a kind of non-renewable resources, along with the increasing of oil exploitation potentiation control DTH hammer bit, oil drilling, repair
Well operations gradually extends to deeper more complicated geology, and inclined shaft, horizontal well and service shaft are more and more, due to casing deformation, bending,
Tiltedly stretch, when common drilling rod removes, casing wall can be often struck at and cause drilling rod impaired, affect drilling rod and remove the quality of rear drilling well, make
Short with the life-span.
Summary of the invention
The technical problem to be solved is: provide the wear-resisting oil drill rocker of length in a kind of service life.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: wear-resisting oil drill rocker, including: drilling rod is originally
Body, is provided with mounting groove on described drilling rod body, in described mounting groove, briquetting and trim ring is provided with bearing inner race,
The inner side of described bearing inner race is evenly arranged with some spring grooves, is radially provided with and cooperates with it in described spring groove
Spring, the inner side of described spring offsets with drilling rod body, and the outside of described spring offsets with bearing inner race, at described bearing inner race
Outside by rotor rotate be provided with bearing outer ring, the outside of described bearing outer ring is provided with wearing layer.
The invention have the advantage that above-mentioned wear-resisting oil drill rocker, rise in horizontal well, inclined shaft and service shaft
During lower drilling rod, if clashing into casing wall, the bearing inner race with spring can stress shrink automatically, can effective bumper and absorbing shock,
It is easy to remove, protects drilling rod, wearing layer after bearing outer ring stress, can be driven simultaneously not stop along bearing inner race under the effect of rotor
Rotating, abrasion resistant effect is good, and drilling life of drill pipe is long.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of the present invention wear-resisting oil drill rocker top half.
In figure: 1, drilling rod body, 2, mounting groove, 3, briquetting, 4, trim ring, 5, bearing inner race, 6, spring groove, 7, spring, 8,
Rotor, 9, bearing outer ring, 10, wearing layer.
Detailed description of the invention
The particular content of the present invention is described in detail below in conjunction with the accompanying drawings with specific embodiment.
As it is shown in figure 1, wear-resisting oil drill rocker, including: drilling rod body 1, described drilling rod body 1 is provided with mounting groove 2,
It is provided with bearing inner race 5, if being provided with in the inner side of described bearing inner race 5 by briquetting 3 and trim ring 4 in described mounting groove 2
Dry spring groove 6, is radially provided with the spring 7 cooperated with it, the inner side of described spring 7 and drilling rod in described spring groove 6
Body 1 offsets, and the outside of described spring 7 offsets with bearing inner race 5, is rotated by rotor 8 in the outside of described bearing inner race 5 and sets
It is equipped with bearing outer ring 9, the outside of described bearing outer ring 9 is provided with wearing layer 10.
When above-mentioned wear-resisting oil drill rocker uses, when horizontal well, inclined shaft and service shaft remove drilling rod body 1, if hit
Hitting casing wall, first buffer brake can be passed to wearing layer 10 by casing wall, and buffer brake is passed to axle by wearing layer 10 successively
Bearing outer-ring 9, rotor 8, bearing inner race 5 and spring 7, now spring 7 forced compression, the counteracting force of spring 7 can effectively buffer and subtract
Shake, meanwhile when bearing outer ring 9 stress, bearing outer ring 9 can rotate along bearing inner race 5, outside bearing under the effect of rotor 8
Circle 9 drive wearing layer 10 rotates along casing wall, and buffering, abrasion resistant effect are good.
Above-mentioned wear-resisting oil drill rocker, when removing drilling rod in horizontal well, inclined shaft and service shaft, if clashing into casing wall, band
The bearing inner race having spring can stress shrink automatically, can effective bumper and absorbing shock, it is simple to removes, protection drilling rod, simultaneously bearing outer ring
Wearing layer can be driven after stress to move along bearing inner race not stall under the effect of rotor, and abrasion resistant effect is good, and drilling life of drill pipe is long.
