Description

DK 162970 CDK 162970 C

Opfindelsen angå et apparat til rensning af overflader med en stråle af rensevæske og med et spulerør, der udmunder i en vippeligt lejret dyse, der er indrettet til at udføre oscillerende svingninger om en akse, der står i hovedsagen vinkel-5 ret på dysens længdeakse, fortrinsvis om en drejetap, og hvor der ved afgangsenden af spulerøret er påbygget et bevæge-organ i form af en rotor i en i et hus anbragt hyraulikmotor, hvilken rotor gennem en excentrikforbindelse er forbundet med den oscillerende svingbart lejrede dyse, der er monteret i 10 huset og står i væskeforbindelse med hydraulikmotorens udløb.BACKGROUND OF THE INVENTION The invention relates to an apparatus for cleaning surfaces with a jet of cleaning fluid and with a flushing pipe which opens into a tiltably stored nozzle adapted to perform oscillating oscillations about an axis generally perpendicular to the longitudinal axis of the nozzle. preferably a pivot pin and wherein at the outlet end of the flushing tube is mounted a moving means in the form of a rotor in a hydraulic motor arranged in a housing, which rotor is connected by an eccentric connection to the oscillating pivotally mounted nozzle mounted in the housing. the housing and is in fluid communication with the outlet of the hydraulic motor.

Fra tysk offentliggørelsesskrift nr. 1.806.634 kendes en sprøjtepistol, der har et slangestykke med en for enden anbragt dyse. Når der ledes væske gennem slangestykket og dysen, vil denne udføre en oscillerende bevægelse, der kan 15 kontrolleres ved at ændre på en række parametre, f.eks. slangestykkets dimensioner eller materialevalget eller ved at begrænse udsvingningsamplituden ved hjælp af en omgivende ramme.German publication specification No. 1,806,634 discloses a spray gun having a hose piece with a nozzle disposed at the end. When fluid is passed through the hose piece and the nozzle, it will perform an oscillating motion which can be controlled by changing a number of parameters, e.g. the dimensions of the hose piece or the choice of material or by limiting the amplitude of the oscillation by means of a surrounding frame.

Desuden kendes fra svejtsisk patentskrift nr. 381.818 et 20 apparat til brug ved rengøring af genstande. Apparatet har en sprøjtemekanisme, der er forsynet med et bevægeorgan i form af en rotor, der drives ved hjælp af to modsat rettede dyser, som udfører en stødvis cirkulær bevægelse. Der er imidlertid ikke tale om en vippeligt lejret dyse.Furthermore, from Swiss patent specification 381,818 there is known an apparatus for use in cleaning objects. The apparatus has a spraying mechanism provided with a moving means in the form of a rotor driven by two oppositely directed nozzles which perform a shock circular motion. However, this is not a tilted nozzle.

25 Fremdeles kendes fra norsk fremlæggelsesskrift nr. 134.200 et apparat til rensning af de indre flader i tanke eller lignende. Dette apparat har en dyseenhed, der har mindst én dyse, der bringes til at rotere ved hjælp af reaktionstrykket fra den afgivne vandmængde. Til at regulere dysens omdrej -30 ningshastighed er der påkoblet en hydraulisk bremseindret-ning. Der er heller ikke her tale om en vippeligt lejret dyse.25 Still, from Norwegian Patent Publication No. 134,200 an apparatus for cleaning the inner surfaces of tanks or the like is known. This apparatus has a nozzle unit having at least one nozzle which is caused to rotate by the reaction pressure of the amount of water delivered. To regulate the speed of the nozzle, a hydraulic brake device is engaged. This is also not a tilted nozzle.

Endelig kendes fra USA patentskrift nr. 1.720.427 en brandslangedyse, der kan udføre oscillerende bevægelser ved hjælp af et som rotor udformet bevægeorgan, der gennem en med krumtap forsynet drivforbindelse er indirekte forbundet med dysen. Den oscillerende bevægelse sker, når vand ledes forbi rotoren og ud gennem dysen. Rotoren og drivforbindelsen er anbragt uden på et hus, hvorpå dysen er monteret. Drivforbindelsen virker som nævnt indirekte på dysen. Dette fordi drivforbindelsen omfatter en plej Istang, der er forbundet med en på huset monteret L-formet drejedel, hvor sidstnævnte så indvirker på dysen. Der er ikke tale om, at plej Istangen er direkte forbundet med dysen. Denne brandslangedyse er uegnet til brug ved rensning af overfladen ved påspuling af højtryksvand, idet en brandslangedyse kun er beregnet til vandtryk på 20 - 25 bar. Ved den foreliggende opfindelse kræves, at dysen skal kunne arbejde ved vandtryk på 175 - 210 bar (og rotoren udføre 8-10 o/m) , altså ca. 10 gange så højt tryk som ved brandslukning. Lader man den kendte brandslangedyse arbejde ved det høje vandtryk, vil den snart gå i stykker, bl.a. fordi den nævnte drivforbindelse ikke virker direkte på dysen, og fordi det nævnte hus er opbygget af mange smådele, der vil rasle løs. Brandslangedysen ville med andre ord ikke kunne fungere driftssikkert.Finally, US Patent No. 1,720,427 discloses a fire hose nozzle which can perform oscillating movements by means of a rotor-shaped moving member indirectly connected to the nozzle through a crank driven drive connection. The oscillating motion occurs when water is passed past the rotor and out through the nozzle. The rotor and drive connection are located outside of a housing on which the nozzle is mounted. As mentioned, the drive connection acts indirectly on the nozzle. This is because the drive connection comprises a groove rod connected to a L-shaped swivel mounted on the housing, the latter then acting on the nozzle. It is not a matter of care that the Istangen is directly connected to the nozzle. This fire hose nozzle is unsuitable for cleaning the surface by flushing high pressure water, since a fire hose nozzle is only intended for water pressure of 20 - 25 bar. The present invention requires that the nozzle be able to operate at water pressures of 175 - 210 bar (and the rotor perform 8-10 rpm), ie approx. 10 times as high as fire extinguishing. If you let the known fire hose nozzle work at high water pressure, it will soon break down, among other things. because said drive connection does not act directly on the nozzle and because said housing is made up of many small parts that will rattle loose. In other words, the fire hose nozzle could not function reliably.

Formålet med opfindelsen er at anvise et apparat af den ovenfor nævnte art, som muliggør en yderst pålidelig oscillerende vipning af vippedysen, især ved høje væsketryk, typisk 175 -210 bar.The object of the invention is to provide an apparatus of the above-mentioned type which enables a highly reliable oscillating tilting of the tilt nozzle, especially at high liquid pressures, typically 175-210 bar.

Excentrikforbindelsen omfatter en åben bøjle, som er monteret på en drejetap på vippedysen og griber ind over en på rotoren anbragt excenterdel. Herved opnås stor driftssikkerhed af apparatet ved de høje vandtryk, der er tale om, fordi dysen, rotoren og bøjlen befinder sig inden i huset, og det hele er meget kompakt bygget. Især bøjlen medvirker til en meget pålidelig kraftoverføring fra rotoren til dysen og giver også mulighed for let justering af vippedysens vippevinkel.The eccentric connection comprises an open bracket mounted on a pivot pin of the rocker nozzle and engages over an eccentric member located on the rotor. This provides high reliability of the apparatus at the high water pressures in question because the nozzle, rotor and bracket are located inside the housing and the whole is very compactly built. In particular, the bracket contributes to a very reliable power transmission from the rotor to the nozzle and also allows for easy adjustment of the tilt angle of the tilt nozzle.

Opfindelsen forklares nedenfor i forbindelse med tegningen, hvor fig. 1 viser en udførelsesform for apparatet ifølge opfindelsen udformet som en sprøjtepistol og set i perspektiv, fig. 2 vippedysens bevægeorgan i form af en i et hus monteret rotor, samt en dertil sluttet excentrikforbindelse - det hele set fra siden, fig. 3 en bøjle set i perspektiv, og fig. 4 en vippedyse med tilhørende drejetap - set i perspektiv.The invention is explained below in connection with the drawing, in which fig. 1 shows an embodiment of the apparatus according to the invention designed as a spray gun and seen in perspective; FIG. Fig. 2 shows the rocker movement in the form of a rotor mounted in a housing and an eccentric connection connected thereto - the whole side view; 3 is a perspective view of a hanger; and FIG. 4 a tilting nozzle with associated pivot pin - viewed in perspective.

Den i fig. 1 viste sprøjtepistol har et håndtag 1 og et dobbelt spulerør 2, hvis ene gren bærer et drejeligt reguleringshåndtag 3. Ved enden af spulerøret er anbragt et hus 4 for en vippeligt lejret dyse 5, der af et bevægeorgan i en i huset anbragt hydraulikmotor drives til at udføre oscillerende svingninger. Dysen har en udsvingningsvinkel til hver side for midteraksen på 5 - 50° og kan f.eks. svinge med en frekvens på 1 - 500 Hz.The FIG. 1, a spray gun 1 has a handle 1 and a double flushing tube 2, one branch of which carries a swivel control lever 3. At the end of the flushing tube is arranged a housing 4 for a tiltably mounted nozzle 5, which is driven by a moving member in a hydraulic motor arranged in the housing. to perform oscillating oscillations. The nozzle has an oscillation angle to each side for the center axis of 5 - 50 ° and can e.g. swing at a frequency of 1 - 500 Hz.

I fig. 2 er vist et eksempel på, hvorledes vippedysen 5, der er udformet i en drejetap 6, via en bøjle 7 og en excentrikdel 8 kan drives i en svingende bevægelse af en hydraulisk rotor 9 med skovle, hvilken rotor passeres af rensevæsken, inden sidstnævnte strømmer til dysen. En udformning af bøjlen 10 og tappen 6 fremgår særlig tydeligt af henholdsvis fig. 3 og 4. Dysen 5 kan være udformet og lejret på mange andre måder end her vist til enten at udnytte væskens strømningshastighed eller trykket. Fordelen ved, at hydraulikmotoren er en rotationsmotor, er, at den, når den er udformet som en impellermotor eller en vingemotor, kan fungere helt uden ventiler.In FIG. 2 shows an example of how the rocker nozzle 5, formed in a pivot 6, can be driven via a hanger 7 and an eccentric part 8 in a swinging motion of a hydraulic rotor 9 with vanes, which rotor is passed by the cleaning fluid before the latter flows to the nozzle. One embodiment of the bracket 10 and the pin 6 is particularly evident in FIG. 3 and 4. The nozzle 5 may be formed and mounted in many ways other than shown here to either utilize the flow rate of the liquid or the pressure. The advantage of the hydraulic motor being a rotary motor is that, when designed as an impeller or vane motor, it can function completely without valves.
