Description
Bærekonstruksjon for en gravemaskin. Support structure for an excavator.
Oppfinnelsen vedrører en bærekonstruksjon for en gravemaskin hvis bæreramme minst på den ene side har et udrevet hjulpar og på den annen side har høyderegulerbare fotstøtter. Slike gravemaskiner beveger seg trinnvis ved hjelp av gravebommen og benyttes ofte for utgraving og rensking av grøfter. Da gravemaskiner av denne type er meget bevegelige, har de i praksis så godt som ingen grense med hensyn til innsatsmulighet, og de benyttes derfor både i sump- og myrområder og i bratt terreng, f.eks. ved rasforskansnin-ger. The invention relates to a support structure for an excavator, the support frame of which at least on one side has a non-driven pair of wheels and on the other side has height-adjustable footrests. Such excavators move step by step with the help of the digging boom and are often used for excavating and cleaning ditches. As excavators of this type are very mobile, in practice they have virtually no limit in terms of input possibilities, and they are therefore used both in swampy and marshy areas and in steep terrain, e.g. in the case of root canals.
Hensikten med foreliggende oppfinnelse er å utforme en slik gravemaskin slik at den ved hjelp av sin bærekonstruksjon kan spenne over meget store grøfter, og ifølge oppfinnelsen oppnås dette ved at det er tilveiebragt en gravemaskin av den innledningsvis nevnte type, ved hvilken gravemaskin hjulene i hjulparet er lagret på en horisontal bjelke, og det mellom horisontalbjelken og hvert hjul er anordnet et nedoverrettet ben hvis lengde er større enn hjulets diameter, hvorved det fremkommer en U-formet ramme. The purpose of the present invention is to design such an excavator so that it can span very large ditches by means of its support structure, and according to the invention this is achieved by providing an excavator of the type mentioned at the outset, in which excavator the wheels in the wheel pair are stored on a horizontal beam, and between the horizontal beam and each wheel there is arranged a downwardly directed leg whose length is greater than the diameter of the wheel, whereby a U-shaped frame appears.
Det er riktignok kjent krananlegg med U-formet eller portallignende ramme med hjul, men de kjente anlegg er bundet til skinner, altså til faste, stasjonære strekninger, slik man f.eks. kjenner det fra kraftverks- eller havneanlegg. Disse krananlegg kan ikke sammenlignes med oppfinnelsens gjenstand, hverken med hensyn til oppbygning eller arbeidsmåte. It is true that there are known crane systems with a U-shaped or gantry-like frame with wheels, but the known systems are tied to rails, i.e. to fixed, stationary sections, such as e.g. know it from power plant or port facilities. These crane systems cannot be compared with the object of the invention, either with regard to structure or working method.

utførelse av arbeider i meget bratt terreng. carrying out work on very steep terrain.
Gravemaskinen har en chassisramme 1 med en dreibar plattform 6 som bærer motoraggregatet for tilveiebringelsen av trykket for det hydrauliske anlegg for betjening av arbeidssylinder-ne 3, 4 °g 5» Plattformen 6 er dreibar om den vertikale akse 2 og over motoraggregatet er det på plattformen anordnet en hytte 7 f°r betjeningen. Plattformen 6 bærer videre braketten 8 hvortil bommen 9 er svingbart lagret om den horisontale akse 12. Graveskuffen Iler anordnet på den frie ende til den andre bomarm 10. Bommen svinges på i og for seg kjent måte ved hjelp av styreorgan i hytten. Chassisrammen 1 bæres på den ene side av et hjulpar 15 og bæres på den andre siden av utliggere 17 med vertikalt forstillbare fotstøt-ter l8. Hjulene 15 er drivløse. The excavator has a chassis frame 1 with a rotatable platform 6 which carries the motor unit for providing the pressure for the hydraulic system for operating the working cylinders 3, 4 °g 5» The platform 6 is rotatable about the vertical axis 2 and above the motor unit there is on the platform arranged a cabin 7 for the staff. The platform 6 further carries the bracket 8 to which the boom 9 is hinged about the horizontal axis 12. The digging bucket Iler arranged on the free end of the second boom arm 10. The boom is swung in a manner known per se by means of a control device in the cabin. The chassis frame 1 is carried on one side by a pair of wheels 15 and carried on the other side by outriggers 17 with vertically adjustable footrests l8. The wheels 15 are driveless.
Aksen 20, som utgjør forbindelsen mellom rammen 1 og hjulparet 15 er utformet som en portal og har således U-form med nedoverrettede ben 21. Ved denne spesielle akseform kan gravemaskinen spenne over brede grøfter og lignende, slik det er vist skjematisk i fig. 1. Hensiktsmessig er lengden til disse nedoverrettede ben 21 større enn diameteren D til hjulene 15. Er i tillegg benene 21 høyderegulerbare relativt den bærende.horisontalbjelke 22, som danner en del av aksen 20, så kan aksen 20 i høy grad tilpasses de forskjellige terrengformasjoner, slik at man kan utføre grave-arbeider selv i usymmetriske grøfter eller i skrått terreng (se fig. 3). The axis 20, which forms the connection between the frame 1 and the pair of wheels 15, is designed as a portal and thus has a U-shape with downward-pointing legs 21. With this special axis shape, the excavator can span wide ditches and the like, as shown schematically in fig. 1. Appropriately, the length of these downward-directed legs 21 is greater than the diameter D of the wheels 15. In addition, if the legs 21 are height-adjustable relative to the supporting horizontal beam 22, which forms part of the axis 20, then the axis 20 can be adapted to a large extent to the different terrain formations , so that digging can be carried out even in asymmetrical trenches or in sloping terrain (see fig. 3).
Fordelaktig er hjulene 15 eller hjulnavene svingbart lagret, med svingeplanet til hjulene eller hjulnavene liggende i planet til den portallignende akse 20. På den måten blir det mulig alltid å sette hjulene 15 loddrett mot grøfteskråningen 24 (fig. 1). For dette formål har de nedoverrettede ben 21 nederst sideveis utragende, sektorformede lasker 23 med flere fortrinnsvis langs en sirkelbue liggende boringer 25 for opptak av en bolt hvormed man kan fiksere stillingen til hjulnavaksen. Advantageously, the wheels 15 or wheel hubs are pivotally mounted, with the pivoting plane of the wheels or wheel hubs lying in the plane of the portal-like axis 20. In this way, it becomes possible to always place the wheels 15 vertically against the ditch slope 24 (fig. 1). For this purpose, the downward-directed legs 21 have at the bottom laterally projecting, sector-shaped lugs 23 with several holes 25 preferably lying along a circular arc for receiving a bolt with which the position of the wheel hub axis can be fixed.
For å muliggjøre tilpassing til de ulike terrengformasjoner er horisontalbjelken 22 utført slik at dens effektive lengde kan reguleres, og horisontalbjelken består da fordelaktig av tele-skopaktige i hverandre forskyvbare rørprofiler eller kasseprofiler. Disse'profiler fikseres innbyrdes ved hjelp av stikkbolter. På den måten kan man få sporvidd.er på opp til 8 m og mer. For at krage-skuffen 11, som i fig. 1 ikke er vist, skal kunne nå ethvert sted i den brede grøft, er rammen 1 lagret forskyvbart relativt horisontalbjelken 22. In order to enable adaptation to the various terrain formations, the horizontal beam 22 is made so that its effective length can be regulated, and the horizontal beam then advantageously consists of telescope-like mutually displaceable pipe profiles or box profiles. These profiles are fixed to each other using studs. In this way, track widths of up to 8 m and more can be obtained. So that the collar drawer 11, as in fig. 1 is not shown, should be able to reach any place in the wide trench, the frame 1 is stored displaceably relative to the horizontal beam 22.
Klemmelignende klemlabber 26, som fordelaktig har U-form holder rammen 1 fast på horisontalbjelken 22. Ved å løsne på klem-skruene 27 kan rammen forskyves relativt horisontalbjelken ved hjelp av den mot marken avstøttede bom. Clamp-like clamping lugs 26, which advantageously have a U-shape, hold the frame 1 firmly on the horizontal beam 22. By loosening the clamping screws 27, the frame can be moved relative to the horizontal beam by means of the boom supported against the ground.
Selvfølgelig er også støttene l8 på de horisontalt svingbare utliggere 17 lagret slik at de kan reguleres i høyden. Of course, the supports l8 on the horizontally pivotable outriggers 17 are also stored so that they can be adjusted in height.
Høyderegulerbarheten for støttene l8 og benene 21 oppnås på lignende måte ved at de utføres som i hverandre glidende kasseprofiler eller rørprofiler som kan fastspennes til hverandre ved klemvirkning eller låses sammen ved hjelp av innstikkbare bolter. The height adjustability of the supports 18 and the legs 21 is achieved in a similar way by the fact that they are designed as sliding box profiles or tube profiles which can be clamped to each other by a clamping action or locked together by means of push-in bolts.
