Abstract
The invention discloses a drill pipe inner wall descaling brush head. The drill pipe inner wall descaling brush head comprises a connecting rod. One end of the connecting rod is connected with a connector. The other end of the connecting rod is hinged to two clamping blocks matched with each other. The two clamping blocks are connected through an elastic structure. The outer walls of the clamping blocks are provided with blades. The non-fixed end of each blade is provided with a brush strip. The blades are arranged obliquely relative to the clamping blocks. The blades on the two clamping blocks are inclined in the same direction. According to the drill pipe inner wall descaling brush head, the two clamping blocks matched with each other are arranged, and the elastic structure is arranged between the two clamping blocks; under the effect of restoring force of the elastic structure, the blades make contact with the inner wall of a drill pipe, dirt weakly and strongly attached to the inner wall of the drill pipe can both be removed through gradual friction movement of the brush strips along the inner wall of the drill pipe, and then the inner wall of the drill pipe is cleaned thoroughly.
Description
Technical field
The present invention relates to petroleum machinery aid field, be specifically related to drilling rod inwall scale removal brush.
Background technology
In the recovery process of oil, drilling rod is a kind of requisite instrument, and drilling rod is reusable, in order to improve the service life of drilling rod, must carry out drilling rod safeguarding cleaning after using finishing drilling bar every time.
Oil drill rocker inner and outer wall after a procedure can form schmutzband, in plant maintenance, oil drill rocker is except needing to remove schmutzband and the rust layer on drilling-rod external wall surface, also need to drilling rod inwall is carried out dirty removing processing, the existing cleaning to drilling rod inwall is mainly rinsed by giant, the cleaning of giant can only remove the dirt that adhesion in drilling rod inwall is more weak, cannot be purged the dirt that some adhesions are stronger by giant.Therefore, use giant to clean drilling rod inwall and be easily caused the inwall halfway problem of cleaning.
Summary of the invention
Present invention aim at providing drilling rod inwall scale removal brush, solve the existing halfway problem of cleaning caused by giant cleaning drilling rod inwall.
The present invention is achieved through the following technical solutions:
Drilling rod inwall scale removal brush, including connecting rod, one end of connecting rod connects joint, the other end is hinged with 2 grip blocks cooperated, being connected by elastic construction between 2 grip blocks, the outer wall of grip block is provided with blade, and the on-fixed end of blade is provided with swipe, described blade is obliquely installed with grip block, and the incline direction of the blade on 2 grip blocks is consistent.
Being currently used for cleaning drilling rod internal dirt and mainly use giant, the cleaning of giant can only remove the dirt that adhesion in drilling rod inwall is more weak, cannot be purged the dirt that some adhesions are stronger by giant.Therefore, use giant to clean drilling rod inwall and be easily caused the inwall halfway problem of cleaning.
Joint of the present invention is for being connected with driving structure, power resources are provided for scale removal brush, the outer wall of described grip block specifically refers to be not provided with the side of elastic construction, described swipe specifically refers to directly and the parts of drilling rod contact internal walls, and described blade and grip block are obliquely installed and specifically refer to blade central shaft between 2 grip blocks and be sequentially arranged.
The work process of the present invention: apparatus for eliminating sludge is placed in drilling rod, during putting into, 2 each grip block extruding elastic constructions, after apparatus for eliminating sludge puts into drilling rod, under the effect of elastic construction restoring force, blade and drilling rod contact internal walls, then apparatus for eliminating sludge it is rotated further by, make swipe and drilling rod inwall gradually fricting movement, and then the dirt of removing drilling rod inwall, rinsed by water the most again.
The present invention is by arranging 2 grip blocks cooperated, it is provided with elastic construction between 2 grip blocks, under the effect at elastic construction restoring force, blade and drilling rod contact internal walls, by swipe and drilling rod inwall gradually fricting movement, the dirt that drilling rod inwall adhesion is more weak can not only be removed, and can remove and adhere to stronger dirt, and then make drilling rod inwall cleaning thoroughly.Avoid the existing halfway problem of cleaning caused by giant cleaning drilling rod inwall.
Further, elastic construction is spring.
Further, grip block uses hard aluminium alloy to make.
Hard aluminium alloy is prior art material, has the advantage that light weight hardness is big, it is possible to alleviates the overall weight of scale removal brush and then reduces power output, having saved the energy.
Further, grip block is the semicylinder of hollow.
Hollow structure is conducive to further reducing the weight of brush, and semicylinder coordinates with the arcuate structure of drilling rod inwall, is more beneficial for the rotation of brush.
Further, at least provided with 2 blades on each grip block.
Multiple blades can improve scale removal effect.
Further, swipe is welded on blade.
Welding manner is firm, is conducive to improving the structural stability of brush.
The present invention compared with prior art, has such advantages as and beneficial effect:
The present invention is by arranging 2 grip blocks cooperated, it is provided with elastic construction between 2 grip blocks, under the effect at elastic construction restoring force, blade and drilling rod contact internal walls, by swipe and drilling rod inwall gradually fricting movement, the dirt that drilling rod inwall adhesion is more weak can not only be removed, and can remove and adhere to stronger dirt, and then make drilling rod inwall cleaning thoroughly.
