Description
FREMGANGSMÅTE OG ANORDNING FOR RENSING AV ET RØRLEGEME I GRUNNEN METHOD AND DEVICE FOR CLEANING A PIPE BODY IN THE GROUND
Det er tilveiebrakt en fremgangsmåte for rensing av et rørlegeme i grunnen. Nærmere bestemt dreier det seg om en fremgangsmåte for rensing av et rørlegeme i grunnen hvor en kabelmaskin som befinner seg i rørlegemet er forsynt med et renseverktøy, idet ka bel maski nen er koplet til en kabel som omfatter en elektrisk leder, og hvor kabelen forløper mellom kabelmaskinen og overflaten. Oppfinnelsen omfatter også en anordning for utøvelse av fremgangsmåten. A method for cleaning a pipe body in the ground is provided. More specifically, it concerns a method for cleaning a pipe body in the ground where a cable machine located in the pipe body is provided with a cleaning tool, the cable machine being connected to a cable that includes an electrical conductor, and where the cable runs between the cable machine and the surface. The invention also includes a device for carrying out the method.
Med kabelmaskin menes i denne sammenheng en elektrisk drevet maskin som er koplet til overflaten ved hjelp av en kabel (wireline) hvor kabelen også er forsynt med en elektrisk leder. In this context, cable machine means an electrically powered machine that is connected to the surface by means of a cable (wireline), where the cable is also provided with an electrical conductor.
I den videre beskrivelse er det tatt utgangspunkt i rensing av et rør med avleiringer, idet en slik arbeidsoperasjon på en fyllestgjørende måte fremhever renseverktøyets fordelaktige trekk. Imidlertid er renseverktøyets bruksområde på ingen måte begrenset til slikt arbeid, idet det vil være anvendelig for en rekke arbeider hvor rør eller bo-rehull skal renses eller utvides og hvor et såkalt "pilothull" er tilstede. In the further description, the starting point is the cleaning of a pipe with deposits, as such a work operation highlights the cleaning tool's advantageous features in a satisfying way. However, the cleaning tool's area of use is in no way limited to such work, as it will be applicable for a number of works where pipes or boreholes are to be cleaned or expanded and where a so-called "pilot hole" is present.
Under drift av røranlegg av ulike slag er det velkjent at avleiringer over tid kan bygge seg opp på rørets innvendige mantelflate. Dette er særlig uheldig når det er tale om lange rør hvor tilkomst er vanskelig og hvor kjemiske rensemetoder er lite effektive. During the operation of pipe systems of various types, it is well known that deposits can build up on the inner surface of the pipe over time. This is particularly unfortunate when it comes to long pipes where access is difficult and where chemical cleaning methods are not very effective.
Norsk patent 320906 beskriver et verktøy som ved å rotere skråstilte børster i et rør bevirker at børstene tildeles en aksial, oscillerende forskyvning i forhold til rørveggen. US-patent 2025009 omhandler renselegemer som er innrettet til å kunne slynges ut mot rørveggen ved hjelp av sentrifugalkraft. Norwegian patent 320906 describes a tool which, by rotating inclined brushes in a pipe, causes the brushes to be assigned an axial, oscillating displacement in relation to the pipe wall. US patent 2025009 deals with cleaning bodies which are arranged to be ejected against the pipe wall by means of centrifugal force.
Det er kjent å anvende renseverktøy som ved sitt frie endeparti er forsynt med et ren-selegeme for rensing av rør. Renseverktøyet forskyves langs røret mens det dreies om rørets lengdeakse. Renseverktøy som er forsynt med dreibare renselegemer har vist seg å være effektive, idet renselegemene under rulling mot rørets innvendige mantel flate bryter opp avleiringer. Norsk patent 324515 og US-patent 2150806 beskriver renseverktøy av denne art. It is known to use cleaning tools which, at their free end, are provided with a cleaning seal body for cleaning pipes. The cleaning tool is moved along the pipe while it is rotated about the pipe's longitudinal axis. Cleaning tools that are equipped with rotatable cleaning bodies have proven to be effective, as the cleaning bodies break up deposits while rolling against the pipe's inner jacket surface. Norwegian patent 324515 and US patent 2150806 describe cleaning tools of this kind.
US-patent 4085808 beskriver en maskin som i ett utførelseseksempel er vist å kunne forme et hull i grunnen. I ett eksempel er det vist å bore et hull som krysser under en vei. Maskinen er forsynt med belter for framdrift. Maskinen sleper etter seg ledninger for kraftforsyning og slanger for borevæske. US patent 4085808 describes a machine which, in one embodiment, is shown to be able to form a hole in the ground. In one example, drilling a hole that crosses under a road is shown. The machine is equipped with belts for propulsion. The machine drags cables for power supply and hoses for drilling fluid behind it.
Selv om renseverktøyet ifølge NO 324515 er relativt effektivt i forhold til andre rense-verktøy, er det et brukerønske å ytterligere forbedre renseeffekten. Although the cleaning tool according to NO 324515 is relatively effective compared to other cleaning tools, there is a user wish to further improve the cleaning effect.
Oppfinnelsen har til formål å avhjelpe eller redusere i det minste én av ulempene ved kjent teknikk. The purpose of the invention is to remedy or reduce at least one of the disadvantages of known technology.
Formålet oppnås i henhold til oppfinnelsen ved de trekk som er angitt i nedenstående beskrivelse og i de etterfølgende patentkrav. The purpose is achieved according to the invention by the features indicated in the description below and in the subsequent patent claims.
Det er tilveiebrakt en fremgangsmåte for rensing av et rørlegeme i grunnen for avleiringer på rørlegemets innvendige mantelflate hvor fremgangsmåten omfatter å: - kople et renseverktøy til en kabelmaskins verktøyaksling som drives av en motor i kabelmaskinen; - forskyve renseverktøyet og kabelmaskinen inn i rørlegemet; - tilføre elektrisk energi til drift av renseverktøyet via en kabel med en elektrisk leder fra overflaten; og - dreie renseverktøyet om renseverktøyet sin lengdeakse, og hvor fremgangsmåten kjennetegnes ved å videre omfatte: - forsyne renseverktøyet med minst ett dreibart opplagret rulleskjær som på sin mantelflate er forsynt med slitelegemer, slik at rulleskjæret har hele sitt virksomme parti rettet i rørlegemets lengderetning og slitelegemene river løs avleiringene når rense-verktøyet dreies. A method has been provided for cleaning a pipe body in the ground for deposits on the pipe body's inner mantle surface where the method comprises: - connecting a cleaning tool to a cable machine's tool shaft which is driven by a motor in the cable machine; - move the cleaning tool and the cable machine into the pipe body; - supply electrical energy for operation of the cleaning tool via a cable with an electrical conductor from the surface; and - rotate the cleaning tool about the longitudinal axis of the cleaning tool, and where the method is characterized by further comprising: - providing the cleaning tool with at least one rotatably stored roller blade which is provided with wear bodies on its outer surface, so that the roller blade has its entire effective part directed in the longitudinal direction of the pipe body and the wear bodies loosens the deposits when the cleaning tool is turned.
Det er overraskende funnet at rulleskjær som har sitt virksomme parti rettet i rørle-gemets lengderetning, oppviser en vesentlig forbedret avvirkning i forhold til et rense-legeme hvor ruller er rettet mot rørlegemets innvendige mantelflate eller mot avleiringer som befinner seg mellom rullene og mantelflaten. It has surprisingly been found that roller shears which have their active part directed in the longitudinal direction of the pipe body, show a significantly improved removal compared to a cleaning body where rollers are directed towards the internal casing surface of the pipe body or towards deposits that are located between the rollers and the casing surface.
Den tilgjengelige effekt fra en kabelmaskin er relativt begrenset, noe som logisk har ført til at utviklingen av renseverktøy for slike maskiner har vært rettet mot rullende verktøy som krever relativt liten effekt. The available power from a cable machine is relatively limited, which has logically led to the development of cleaning tools for such machines being aimed at rolling tools that require relatively little power.
Det er velkjent at et borekronelignende verktøy krever vesentlig større effekt enn rullende verktøy for å kunne arbeide, og det er således ikke nærliggende for en fagmann å forsyne en kabelmaskin med et verktøy av denne art. It is well known that a drill bit-like tool requires significantly greater power than a rolling tool in order to work, and it is therefore not obvious for a professional to supply a cable machine with a tool of this kind.
Den mest kjente form for kabelmaskin er ofte betegnet wirelinetraktor. Ofte er kabel-maskiner forsynt med fremdriftsmaskineri i form av hjul, belter eller forskyvbare gri-pere som er innrettet til å kunne ligge an mot en rørvegg. The most well-known form of cable machine is often referred to as a wireline tractor. Cable machines are often equipped with propulsion machinery in the form of wheels, belts or displaceable grippers which are arranged to be able to rest against a pipe wall.
Fremgangsmåten kan omfatte å forsyne renseverktøyet med minst ett langsgående eller skru eli njeformet spor på renseverktøyets utvendige mantelflate. The method may comprise providing the cleaning tool with at least one longitudinal or screw-shaped groove on the cleaning tool's outer casing surface.
Fremgangsmåten kan utøves ved hjelp av en kabelmaskin som befinner seg i et rørle-geme i grunnen og hvor kabelmaskinen er forsynt med et renseverktøy for rensing av avleiringer i rørlegemet idet kabelmaskinen er koplet til en kabel med en elektrisk leder, idet kabelen forløper mellom kabelmaskinen og overflaten. Renseverktøyet er forsynt med minst ett dreibart opplagret rulleskjær som har sitt virksomme parti rettet i rørlegemet sin lengderetning. The method can be carried out with the help of a cable machine which is located in a pipe body in the ground and where the cable machine is provided with a cleaning tool for cleaning deposits in the pipe body, as the cable machine is connected to a cable with an electrical conductor, as the cable runs between the cable machine and the surface. The cleaning tool is equipped with at least one rotatably stored roller blade whose active part is directed in the longitudinal direction of the pipe body.
Med rulleskjæret sitt virksomme parti menes den delen av rulleskjæret sin mantelflate som er i inngrep med for eksempel avleiringer i rørlegemet. By the roller cutter's active part is meant the part of the roller cutter's mantle surface that engages with, for example, deposits in the pipe body.
Kabelmaskinen kan være forsynt med en motor som tilføres elektrisk energi via kabelen, og motoren er innrettet til å kunne dreie en verktøyaksling. Renseverktøyet er typisk koplet til kabelmaskinen sin verktøya ksling som er dreibar og drevet om rense-verktøyet sin lengdeakse. Et renseverktøy ifølge oppfinnelsen har således en virkemå-te som tilsvarer en borekrone slik det er kjent fra boring av hull i grunnen. The cable machine can be provided with a motor which is supplied with electrical energy via the cable, and the motor is arranged to be able to turn a tool shaft. The cleaning tool is typically connected to the cable machine's tool shaft, which is rotatable and driven about the cleaning tool's longitudinal axis. A cleaning tool according to the invention thus has a mode of operation that corresponds to a drill bit as is known from drilling holes in the ground.
Et renseverktøy i form av en borekrone som drives av en kabelmaskin, kan således anvendes for rengjøring av et rørlegeme i grunnen. A cleaning tool in the form of a drill bit that is driven by a cable machine can thus be used for cleaning a pipe body in the ground.
Renseverktøyet kan være forsynt med minst ett langsgående eller skruelinjeformet spor på sin utvendige mantelflate. Sporet bidrar til at løsgjort materiale lettere kan ledes forbi renseverktøyet under renseverktøyets forskyvning i rørlegemet. The cleaning tool may be provided with at least one longitudinal or helical groove on its outer casing surface. The groove helps loosened material to be more easily guided past the cleaning tool during the cleaning tool's displacement in the pipe body.
Kabelmaskinen kan utgjøres av en wirelinetraktor. The cable machine can consist of a wireline tractor.
Fremgangsmåten og anordningen i henhold til oppfinnelsen muliggjør en vesentlig øket avvirkning under rensing av rørlegemer, noe som medfører at nedstengningsti-den av relativt kostbare anlegg under renseoperasjoner reduseres. The method and device according to the invention enables a significantly increased removal during cleaning of pipe bodies, which means that the shutdown time of relatively expensive facilities during cleaning operations is reduced.
I det etterfølgende beskrives et eksempel på en foretrukket utførelsesform som er anskueliggjort på medfølgende tegning, hvor: Fig. 1 perspektivisk viser en kabelmaskin som befinner seg i et rørlegeme og som In what follows, an example of a preferred embodiment is described which is visualized in the accompanying drawing, where: Fig. 1 shows a perspective view of a cable machine which is located in a pipe body and which
er forsynt med et verktøy i overensstemmelse med oppfinnelsen. is provided with a tool in accordance with the invention.
På tegningen betegner henvisningstallet 1 et rørlegeme hvor det har dannet seg en innvendig avleiring 2. En kabelmaskin 4 i form av en wirelinetraktor er under forskyvning i rørlegemet 1, idet kabelmaskinen 4 er forsynt med et renseverktøy 6. In the drawing, the reference number 1 denotes a pipe body where an internal deposit 2 has formed. A cable machine 4 in the form of a wireline tractor is being displaced in the pipe body 1, the cable machine 4 being equipped with a cleaning tool 6.
Kabelmaskinen 4 er koplet til en kabel 8 som omfatter en ikke vist elektrisk leder og som forløper til overflaten. The cable machine 4 is connected to a cable 8 which comprises an electrical conductor (not shown) and which extends to the surface.
Renseverktøyet 6 er koplet til kabelmaskinen 4 ved hjelp av en verktøya ksling 10 som drives av en motor 12 i kabelmaskinen 4. Motoren 12 tilføres elektrisk energi via kabelen 8 og er innrettet til å kunne dreie verktøyakslingen 10 om renseverktøyet 6 sin lengdeakse 14. The cleaning tool 6 is connected to the cable machine 4 by means of a tool shaft 10 which is driven by a motor 12 in the cable machine 4. The motor 12 is supplied with electrical energy via the cable 8 and is designed to be able to turn the tool shaft 10 about the cleaning tool 6's longitudinal axis 14.
Renseverktøyet 6 er forsynt med tre rulleskjær 16. Rulleskjærene 16 er utformet med en ru utvendig mantelflate 18, idet relativt harde slitelegemer 20 er festet til mantelflaten 18. The cleaning tool 6 is provided with three roller cutters 16. The roller cutters 16 are designed with a rough outer casing surface 18, with relatively hard wearing bodies 20 being attached to the casing surface 18.
Rulleskjærene 16 er opplagret i renseverktøyet 6 sin kropp 22 slik at rulleskjærene 16 sitt virksomme parti 24, som er i inngrep med avleiringen 2, arbeider i rørlegemet 1 sin lengderetning og står tilnærmet radialt i forhold til lengdeaksen 14. The roller cutters 16 are stored in the body 22 of the cleaning tool 6 so that the active part 24 of the roller cutters 16, which engages with the deposit 2, works in the longitudinal direction of the pipe body 1 and stands approximately radially in relation to the longitudinal axis 14.
Siden mantelflaten 18, blant annet av plasshensyn, er konisk, er rulleskjærene 16 opplagret skråstilt i forhold til lengdeaksen 14. Since the mantle surface 18, for reasons of space, among other things, is conical, the roller cutters 16 are stored at an angle in relation to the longitudinal axis 14.
Renseverktøyet 6 er forsynt med spor 26 i sin utvendige mantelflate 28. Sporene 26 er noe skråstilt i forhold til lengdeaksen 14 og anordnet for å underlette passasje av løse avleiringer forbi renseverktøyet 6. The cleaning tool 6 is provided with grooves 26 in its outer casing surface 28. The grooves 26 are slightly inclined in relation to the longitudinal axis 14 and arranged to facilitate the passage of loose deposits past the cleaning tool 6.
Når motoren 12 dreier renseverktøyet 6, river rulleskjærene 16 sine slitelegemer 20, som befinner seg på rulleskjærene sine virksomme partier 24, ut avleiringer 2, idet avleiring-ene 2 etter at de er løsnet kan strømme forbi verktøyet 6 blant annet via sporene 26. When the motor 12 rotates the cleaning tool 6, the wear bodies 20 of the roller cutters 16, which are located on the active parts 24 of the roller cutters, tear out deposits 2, as the deposits 2 after they have been loosened can flow past the tool 6 via the grooves 26, among other things.
