Description
Understell for byggemaskiner. Chassis for construction machinery.
Oppfinnelsen angår et understell for byggemaskiner, spesielt gravemaskiner med en ramme, som på den ene siden har et hjulpar og på den andre siden har fotstøtter, og hvor hvert hjul er festet på en bærearm, som i det vesentlige forløper parallelt med hjulplanet. The invention relates to a chassis for construction machines, in particular excavators with a frame, which on one side has a pair of wheels and on the other side has footrests, and where each wheel is fixed on a support arm, which essentially runs parallel to the wheel plane.
Av hensyn til byggemaskinenes og spesielt gravemaskinenes stabilitet har disse som regel en betydelig akselavstand, to meter eller mer, slik at hjulene løper utenfor rammens eller chassisets side-begrensning. Da byggemaskiner og særlig gravemaskiner ofte må arbeide - under plassmessig meget trange forhold, foreslås det ifølge oppfinnelsen et understell for en byggemaskin, særlig en gravemaskin, med en ramme, som på den ene siden er markunderstøttet ved hjelp av et hjulpar og på den andre siden er markunderstøttet ved hjelp av to fotstøtter, . og hvor hvert hjul i hjulparet er opplagret på en med rammen forbundet og i det vesentlige parallelt med hjulplanet forløpende bærearm, og det som kjennetegner understellet ifølge oppfinnelsen er at hjulparets sporvidde kan reduseres ved at i det minste bærearmen til et hjul er forskyvbart opplagret i retning av hjulaksen og mot kjøretøyets midte, på en på rammen anordnet føringsskinne. Takket være dette forslag kan understellets normale akseavstand valgfritt forandres innenfor de gren-ser som er gitt ved konstruksjonen, slik at byggemaskinen, spesielt gravemaskinen, kan kjøre og bevege seg på meget smale veier, noe som f. eks. er av betydning ved bruk av gravemaskiner på kirkegårder. For the sake of the stability of the construction machines and especially the excavators, these usually have a considerable wheelbase, two meters or more, so that the wheels run outside the lateral limitation of the frame or chassis. As construction machines and especially excavators often have to work - under very tight conditions in terms of space, the invention proposes a chassis for a construction machine, in particular an excavator, with a frame, which on one side is supported on the ground by means of a pair of wheels and on the other side is supported on the ground by means of two foot supports, . and where each wheel in the pair of wheels is supported on a support arm connected to the frame and running substantially parallel to the wheel plane, and what characterizes the chassis according to the invention is that the track width of the pair of wheels can be reduced by at least the support arm of one wheel being displaceably supported in the direction of the wheel axis and towards the center of the vehicle, on a guide rail arranged on the frame. Thanks to this proposal, the undercarriage's normal center distance can optionally be changed within the limits given by the construction, so that the construction machine, especially the excavator, can drive and move on very narrow roads, which e.g. is important when using excavators in cemeteries.
For å illustrere oppfinnelsen skal denne i det følgende be-skrives nærmere under henvisning til et utførelseseksempel, som dog ikke begrenser oppfinnelsen. Fig. 1 viser et oppriss av understellet for en liten gravemaskin. Fig. 2 viser et snitt etter linjen A - A i fig. 1. In order to illustrate the invention, it will be described in more detail below with reference to an embodiment, which does not, however, limit the invention. Fig. 1 shows an elevation of the undercarriage for a small excavator. Fig. 2 shows a section along the line A - A in fig. 1.
Gravemaskinens i og for seg kjente konstruksjonsdeler som ikke er gjenstand for oppfinnelsen, er utelatt av oversiktlighetshen-syn. Den viste gravemaskin har en ramme 1, på hvilken det er anordnet en plattform, som er dreibar om sin vertikale akse. Plattformen om-fatter drivaggregatet, en betjeningsplass og en støtte for utliggerens leddede lagring. På den ene siden bærer rammen et hjulpar 2 og på den andre siden to horisontalt svingbare fotstøtter. Ifølge oppfinnelsen er de to hjul som danner hjulparet 2 lagret slik at de er forskyvbare The construction parts known in and of themselves of the excavator, which are not the subject of the invention, have been omitted for reasons of clarity. The excavator shown has a frame 1, on which a platform is arranged, which is rotatable about its vertical axis. The platform includes the drive unit, an operating station and a support for the articulated storage of the boom. On one side the frame carries a pair of wheels 2 and on the other side two horizontally pivotable footrests. According to the invention, the two wheels that form the wheel pair 2 are stored so that they are displaceable
i retning av sin akse 3- Hjulene er ikke festet umiddelbart til rammen 1, men under mellomkobling av bærearmer H, som f. eks. kan bestå av boksprofiler som på endene er flensforbundet med hjulnav. Forskyvbar-heten av hjulparets 2 hjul i retning av deres akse 3 oppnås ved at bærearmene 4 er regulerbart utformet. For dette formål er rammens 1 frontside 5 utformet som en T-formet skinneføring, henholdsvis bærer frontsiden 5 en slik skinneføring 7- På rammesiden er bærearmene 4 forsynt med hoder 6, som igjen er utformet som underskårne U-profiler (fig. 2), som i formsluttet anordning griper om skinneføringen 7- An-slag 8 begrenser skinneføringens 7 ender, som dog på ingen måte må falle sammen med rammens 1 sidebegrensningskanter 10, idet skinnefør-ingens lengde forsåvidt kan være større eller mindre enn rammens bred-de. Ved hjelp av klemskruer 11 strammes hodene 6 mot skinneføringen 7- in the direction of its axis 3- The wheels are not attached immediately to the frame 1, but during intermediate coupling of support arms H, which e.g. can consist of box profiles which are flanged at the ends with wheel hubs. The displaceability of the wheels of the pair of wheels 2 in the direction of their axis 3 is achieved by the support arms 4 being adjustable. For this purpose, the front side 5 of the frame 1 is designed as a T-shaped rail guide, respectively the front side 5 carries such a rail guide 7- On the frame side, the support arms 4 are provided with heads 6, which are again designed as undercut U-profiles (fig. 2), which in a form-locked device grips the rail guide 7 - Stops 8 limit the ends of the rail guide 7, which, however, must in no way coincide with the side limiting edges 10 of the frame 1, as the length of the rail guide can certainly be greater or less than the width of the frame. Using clamping screws 11, the heads 6 are tightened against the rail guide 7-
Hvis akselbredden skal forandres, presses gravemaskinens ut-ligger mot marken på rammens hjulside, noe som gjør det mulig å løfte hjulparet 2. Boltene 11 løsnes og hjulene kan enkeltvis forskyves i akseretningen 3 langs skinneføringen (pilen 9). Når den ønskede ak-selbredde er innstilt, trekkes boltene til igjen. Naturligvis kan denne regulering f. eks. også oppnås med en gjenget spindel. I så til-felle anordnes hensiktsmessig en slik spindel for hvert hjul og lagres parallelt med skinneføringen 7. En regulering som omtalt, kan også gjennomføres ved hjelp av pneumatisk eller hydraulisk sylinder. If the axle width is to be changed, the excavator's outrigger is pressed against the ground on the wheel side of the frame, which makes it possible to lift the pair of wheels 2. The bolts 11 are loosened and the wheels can be moved individually in the direction of the axis 3 along the rail guide (arrow 9). When the desired axle width has been set, tighten the bolts again. Naturally, this regulation can e.g. also achieved with a threaded spindle. In this case, such a spindle is appropriately arranged for each wheel and stored parallel to the rail guide 7. A regulation as discussed can also be carried out using a pneumatic or hydraulic cylinder.
