Description
Technical field
The present invention relates to cleaning device field, particularly, relate to the cleaning mechanism that internal dirt is removed in the advance of a kind of spiral.
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 maintenance at every turn clean after using drilling rod to drilling rod.After prolonged, drilling rod inwall easily grows iron rust to drilling rod, and can be stained with a large amount of mud solid phase particles and greasy dirt.The dirt of drilling rod inwall can impact the use next time of drilling rod, the drilling rod being attached with scrap thing can have influence on quality and the operating efficiency of drilling well next time, dirt also can corrode the inwall of drilling rod, have a strong impact on the service life of drilling rod and threaten drilling safety, therefore, cleaning must be carried out to drilling rod inwall after drilling rod uses a period of time, existing cleaning device to drilling rod clean not thoroughly, need repeated washing to cause efficiency lower.
Summary of the invention
Technical problem to be solved by this invention is to provide the cleaning mechanism that internal dirt is removed in the advance of a kind of spiral, to overcome the problem that clean thoroughly, need repeated washing cause efficiency lower of existing cleaning device to drilling rod.
The present invention's adopted technical scheme that solves the problem is: spiral advances and removes the cleaning mechanism of internal dirt, comprise hydraulic jack, the output of hydraulic jack is connected with two symmetrically arranged fixed heads, the inner side of two fixed heads is connected by spring, the natural length of spring is consistent with the internal diameter of oil drill rocker, the end of fixed head outwards turns down formation holddown groove, is provided with scouring pad in holddown groove; The end of hydraulic jack is provided with rotating cylinder, the outer wall of rotating cylinder is provided with gear I, is coordinated with gear I by the gear II of Electric Machine Control, and fixed head adopts aluminium alloy to make.The existing Clean-cleaning device to oil drill rocker inwall is all generally to adopt cleaning to drilling rod inwall drilling rod inwall with the use of by water high-pressure injection of high-pressure spray pump and fluid jet nozzle, or adopt the cleaning that simply rubs, although the water of high pressure spray injection has certain pressure, the part dirt of drilling rod inwall can be cleaned, but intractable dirt removal stronger for some adhesions can not fall by the limited strength of hydraulic pressure, causes the cleaning inside of oil drill rocker not thorough, if the parts contacted with drilling rod during friction cleaning can not contact completely with drilling rod inwall, in order to make a clean direction of thoroughly need changing, the friction that drilling rod carries out again is cleaned, repeat and reduce operating efficiency, fixed head of the present invention adopts aluminium alloy to make, aluminium alloy is prior art material, have that good intensity is less, plasticity is high, corrosion resistance is strong, therefore flexible lower adjustable at spring of distance between two fixed heads, Compress Spring makes the distance between two fixed heads reduce until cleaning device can be put into drilling rod, the outer wall of scouring pad is made tightly to be fitted in drilling rod inwall, now, spring is in compressive state, there is restoring force, scouring pad is withstood on drilling rod inwall by this restoring force firmly, primer fluid compressing cylinder, scouring pad moves along drilling rod inwall, cleaning drilling rod inwall is realized by the friction between scouring pad and drilling rod inwall, mutual friction energy between scouring pad and drilling rod inwall is by thorough for the intractable dirt removal of drilling rod inwall, promote scouring pad by hydraulic jack axially to clean drilling rod inwall at drilling rod, motor driven gear II of the present invention rotates, gear II driven gear I rotates, and then make to rotate with the scouring pad of drilling rod contact internal walls by the rotary type of rotating cylinder, the rotation of scouring pad is cleaned drilling rod inwall in drilling rod radial direction, clean to water flowing in drilling rod again after scouring pad friction, so, the present invention axially and in radial direction carries out friction cleaning to drilling rod inwall at drilling rod simultaneously, can be thoroughly clean by drilling rod inwall without the need to repeating, overcome the problem that clean thoroughly, need repeated washing cause efficiency lower of existing cleaning device to drilling rod.
Further, fixed head curves inwardly formation arc.Arc coordinates with drilling rod inwall, be convenient to make scouring pad to be formed to coordinate with drilling rod inwall arcuate structure, scouring pad and drilling rod inwall are fitted more closely, the frictional force of increase scouring pad and drilling rod inwall, what drilling rod inwall was cleaned is more thorough.
Further, scouring pad is provided with the groove coordinated with holddown groove.What the arranging of groove was convenient on the one hand scouring pad snaps in fixed head, avoid on the other hand holddown groove directly and drilling rod contact internal walls cause scratching of drilling rod.
Further, scouring pad two two coordinates besieged city cylinder, and the outer wall of cylinder and the inwall of drilling rod are fitted.So can increase friction area to greatest extent, make drilling rod inwall by scouring pad contact friction, clean efficiency can be improved.
To sum up, the invention has the beneficial effects as follows:
1, the present invention axially cleans drilling rod inwall at drilling rod by promoting scouring pad by hydraulic jack, drive the rotation of scouring pad that scouring pad is cleaned drilling rod inwall in the radial direction of drilling rod by gear II and cooperatively interacting of gear I, axially and in radial direction friction cleaning is carried out to drilling rod inwall at drilling rod simultaneously, can be thoroughly clean by drilling rod inwall without the need to repeating, overcome the problem that clean thoroughly, need repeated washing cause efficiency lower of existing cleaning device to drilling rod.
2, the present invention is by the formation arc that curved inwardly by fixed head, be convenient to make scouring pad to be formed to coordinate with drilling rod inwall arcuate structure, what scouring pad and drilling rod inwall were fitted is tightr.
