Description

Anordning for manøvring av ramloddføring for pelingsaggregat. Device for maneuvering the ram plumb line for piling units.

Oppfinnelsen vedrorer en anordning ved pelingsaggregat med ramlodd og nedsvingbar foring for dette i kombinasjon med traktorkran eller annet motorkjoretoy med på dettes understell om en The invention relates to a device for a piling unit with a ram weight and swing-down liner for this in combination with a tractor crane or other motorized vehicle with on its undercarriage about a

vertikal akse dreibart anbragt overdel eller kranhus med fortil på dette i hoyderetning svingbart anbragt kort kranarm, med hvilken foringen i oppreist stilling kan heves og senkes til den med sin nedre ende hviler mot marken, idet ramloddforingeri nær den nedre ende er universelt leddforbundet med den korte kranarm samt er forskyvbar 1 forhold 'til denne i dennes lengderetning samt nærmere den ovre ende er forbundet med en fremover vertical axis rotatably placed upper part or crane housing with a vertically pivotable short crane arm in front of this, with which the lining in an upright position can be raised and lowered until it rests with its lower end against the ground, the ram plumb lining near the lower end being universally articulated with the short crane arm and is displaceable relative to this in its longitudinal direction and closer to the upper end is connected to a forward

Videre må ved innstilling fremover og bakover av i : ramloddfbringen hele maskinen forflyttes, hvilket kan være vans^ kelig, når det fordres nbyaktighet, og dertil stadig forflytting j i sideretning, hvilket alt sammen er meget tidskrevende. Videre er foruten de liner som anvendes for lbfting av loddet og en for nedslagning beregnet bjelke også anordnet liner for oppreis-ning av ldddfbringen , hvilke sistnevnte liner går ut fra for-I skjellige steder av masten og er til hindring, utsettes for sli-tasje samt medfbrer tidskrevende arbeidsoperasjoner yed anbring-*-else av ramloddfbringen i eller ut av arbeidsstilling. Det er derfor et formål å erstatte disse liner foruten de for ramloddet og oppheisningen av pelen nbdvendige liner med hydrauliske ari-I ordninger. said wall. Furthermore, when setting forwards and backwards of the ram solder, the entire machine must be moved, which can be difficult, when precision is required, and in addition constant movement in the lateral direction, which is all very time-consuming. Furthermore, in addition to the lines used for weighting the plumb line and a beam intended for striking down, there are also lines arranged for straightening the ldddfbringen, which latter lines come out from different places of the mast and are an obstacle, are exposed to wear and tear and entails time-consuming work operations and placement* of the ram solder in or out of the working position. It is therefore an aim to replace these lines, in addition to the lines required for the ram solder and the lifting of the pile, with hydraulic ari-I systems.

! Formålet med oppfinnelsen er således å tilveiebringe en meré ,an-t vendbar og hurtigere inaskin og dette oppnåes ifblge pppfinnelséri ved at forbindelsen mellom ram^pddfbringen og den korte kranarm består av et i kranarmen i dennes lengderetning forskyvbart såvel som om sin lengdeakse dreibart lagret organ og et med dette om en mot dets dreiningsakse perpendikulær leddaksel dreibart forbundet organ med feste for en foring med dette leddbart for*^bindende, mot foringens lengderetning perpendikulær aksel»:;*..'■ :* '..*> ! The purpose of the invention is thus to provide a more maneuverable and faster machine and this is achieved according to the invention in that the connection between the frame and the short crane arm consists of a body which can be displaced in the crane arm in its longitudinal direction as well as rotatable about its longitudinal axis. and a with this about a joint shaft perpendicular to its axis of rotation rotatably connected body with attachment for a liner with this articulated for*^binding, to the longitudinal direction of the liner perpendicular axis»:;*..'■ :* '..*>

Fig. 1 viser fra siden et kjoretoy med et på dette montert pel- \ l ingsaggregat ifblge oppfinnelsen med en ramloddforing dels i horisontal transportstilling og dels delvis i oppreist stilling. Fig. 2 viser en for forbindelse av pelingsaggregatets ramloddforing med kjbretbyet beregnet leddanordning. i I fig. 1 vises et kjoretoy, som har et understell lo og en overdel 11 som er dreibar på dette om en vertikal akse. På kjbretbyet er ved hjelp av en med 12 generelt betegnet leddanordning montert en ramloddforing 13. Leduanordningen 12 er innrettet i således, at ramloddfbringen kan svinges i to mot hverandre vinkelrette vertikalplan og omkring en parallelt med men på noen avstand fra ramloddfbringens lengdeakse forldpende dreieakse og forskyves i såvel lengderetningen som mot og fra kjoretoyet. For utfbrelse av disse bevegelser er anordnet .hydrauliske anordninger !■+, 15 og 16, av hvilke to lk i den ene ende er festet til mastens ovre halvdel og i den andre ende er forbundet med j kjbretbyet, fortrinnsvis i nærheten av dettes bakre hjbrner, slik at de i kjbretbyets lengderetning sett danner en omvendt V, mens to hydrauliske anordninger 15 er innkoblet mellom kjbretbyet og leddanordningen 12 og endelig er de to hydrauliske anordninger lu anordnet mellom leddanordningen 12 og ramloddfbringen 13. I ■ fig. 1 er bare medtatt hva som er nbdvendig for oppfinnelsens forståelse, og mange vesentlige detaljer slik som ramlouuet, dettes liner osv. er utelatt, hvilket imidlertid ikke turde med-fbre noen vanskeligheter for fagmannen ved forståelse av tegningene. 'Leddanordningen 12 omfatter et hylseorgan 13 og på hver side av dette anordnete,- oppadrettete grener 17, hvilke, som det fremgår av fig. 2, smalner mot den frie ende, slik at de fra siden stort sett er triangulære. Grenene 17 utgjor en del av en U-formet , holder, med hvis midtparti hylseorganet 18 er fast forbundet og strekker seg langs de triangulære greners 17 basis. Ved grene-- nes 17 bakre ende er på hylseorganet 18 anordnet nedadrettete Fig. 1 shows from the side a vehicle with a mounting unit mounted on it according to the invention with a ram lead liner partly in horizontal transport position and partly in upright position. Fig. 2 shows a joint device calculated for the connection of the piling unit's ram solder lining with the kjbretbyet. in I fig. 1 shows a vehicle which has a chassis 11 and an upper part 11 which is rotatable on this about a vertical axis. A ram solder bushing 13 is mounted on the bridge by means of a joint device generally denoted by 12. The joint device 12 is arranged in such a way that the ram solder bearing can be swung in two vertical planes perpendicular to each other and around a continuous axis of rotation parallel to but at some distance from the longitudinal axis of the ram solder bearing and displaced both in the longitudinal direction and towards and from the vehicle. To carry out these movements, hydraulic devices !■+, 15 and 16 are arranged, of which two links at one end are attached to the upper half of the mast and at the other end are connected to the j kibretby, preferably near its rear corners , so that in the longitudinal direction of the bridge they form an inverted V, while two hydraulic devices 15 are connected between the bridge and the joint arrangement 12 and finally the two hydraulic devices lu arranged between the joint arrangement 12 and the ram solder 13. I ■ fig. 1, only what is necessary for the understanding of the invention has been included, and many important details such as the frame, its lines, etc. have been omitted, which, however, should not cause any difficulties for the person skilled in the art when understanding the drawings. The joint arrangement 12 comprises a sleeve member 13 and on each side of this arranged, - upwardly directed branches 17, which, as can be seen from fig. 2, narrows towards the free end, so that they are largely triangular from the side. The branches 17 form part of a U-shaped , holder, with whose middle part the sleeve member 18 is firmly connected and extends along the base of the triangular branches 17. At the rear end of the branches 17, the sleeve member 18 is arranged downwards
