Description

sooaszs-0 Uppfinningen har därför fått till uppgift atE'åštedkómmá èttf lyftarmssystem för en skoplastare, vilket med enklaste medel och enklaste hantering medger omställning från skopa till användning som gaffeltruck. sooaszs-0 The invention has therefore been given the task of providing a lifting arm system for a bucket loader, which with the simplest means and simplest handling allows conversion from bucket to use as a forklift.

Detta uppnås genom uppfinningen i enlighet med de i patent- kravets l kännetecknande del angivna åtgärderna.This is achieved by the invention in accordance with the measures specified in the characterizing part of claim 1.

För detta ändamål är i frontlastarens chassi framför och nedanför lyftarmslagret anordnade två ytterligare lager- ställen i vilka den arbetsredskapets eventuella tippning kontrollerande_hydraulcylinderenheten alternativt kan lagras medelst en omflyttbar lagerbult på sådant sätt att i ena positionen lastskopan utför en för skopanvändning erforder- lig tippningsrörelse medan i den andra positionen arbets- redskapet endast kan lyftas och sänkas parallellt med sig självt, såsom detta erfordras vid användning som gaffel- 'truck.For this purpose, two additional storage places are arranged in the front loader chassis in front of and below the lifting arm bearing, in which the tilting control of the work tool can be stored by means of a movable bearing bolt in such a way that in one position second position the implement can only be raised and lowered in parallel with itself, as required for use as a forklift.

Anordningen enligt uppfinningen kan förbättras ytterligare 'genom att hydraulcylindern för skopmanövrering vid sin mot chassit vända ände uppvisar två alternativt till användning kommande, efter varandra belägna lagerurborrningar.The device according to the invention can be further improved in that the hydraulic cylinder for bucket operation at its end facing the chassis has two alternatively usable bearing bores located one after the other.

Uppfinningstanken tillåter många olika utföringsvarianter.The inventive concept allows for many different embodiments.

En därav har återgivits på bifogade ritning. Därvid visar: fig. l en sidovy av en skoplastares främre del 'med monterad skopa, och fig. 2 en sidovy av samma lastare som fig. l men omrustad till användning som gaffeltruck.One of these has been reproduced in the attached drawing. In the drawing: Fig. 1 shows a side view of a front part of a bucket loader with a bucket mounted, and Fig. 2 shows a side view of the same loader as Fig. 1 but equipped for use as a forklift.

Vid chassits 16 övre ände sitter i ett lager l en framåt- riktad lyftarm 7 vilken alternativt kan förses med en last- skopa l4 enligt fig. l eller en lastgaffel 18 enligt fig. 2.At the upper end of the chassis 16 there is in a bearing 1 a forward-facing lifting arm 7 which can alternatively be provided with a loading bucket 14 according to Fig. 1 or a loading fork 18 according to Fig. 2.

Detta redskap 14 resp. 18 är nedtill på sin baksida sväng- bart lagrat kring en första tväraxel 15 vid lyftarmens 7 främre_ände. Ovanför detta lager 15 sitter på redskapets 14 resp. l8 baksida ytterligare ett lager 13 resp. l3'. vid 8008328-0 lyftarmen eller om två.lyftarmar finns vid att dësšd"båëa lyftarmar 7 förbindande mellanstycke 25 är en länkarm 26 fastsvetsad, i vars båda ändar sitter lugertappar 10 resp. 22. Vid lagertappen 22 angriper en hydraulcylinders 6 kolvstâng. Hydraulcylindern 6 är med sin andra ände vid 17 fastlänkad i chassit l6. dPå länkarmens 26 länktapp 10 sitter svängbart lagrat en på grund av sin krökta form som bananarm betecknad dubbel- arm 8, vilken vid sina båda ändar har ledtappar 9 och 12.This tool 14 resp. 18 is pivotally mounted at the bottom of its rear about a first transverse axis 15 at the front end of the lifting arm 7. Above this bearing 15 sits on the tool 14 resp. l8 back another layer 13 resp. l3 '. at 8008328-0 the lifting arm or if there are two lifting arms in that the connecting piece 25 connecting these two lifting arms 7 is a link arm 26 welded, in both ends of which there are lug pins 10 and 22, respectively. with its other end at 17 fixed in the chassis 16. d On the link pin 10 of the link arm 26 there is a pivotally mounted double arm 8, which due to its curved shape is referred to as a banana arm, which has guide pins 9 and 12 at both ends.

Den undre bananarmsänden är genom en stång ll ledat förbunden med arbetsredskapets l4 resp. 18 lager l3 resp. l3'. På bananarmens 8 övre ände sitter en av en hydraulcylinder 3 och en kolvstång 21 bildad, hydrauliskt manövrerad kolv- cylinderenhet för arbetsredskapets manövrering. Denna hydraulcylinderenhet 3 är med sin kolvstâng 21 fastlänkad vid ledtappen 9 i bananarmen 8 och sitter med sin andra ände i en nedan närmare beskriven lageranordning i fordonets chassi 16.The lower end of the banana arm is connected by a rod 11 to the work tool 14 or 4, respectively. 18 lager l3 resp. l3 '. On the upper end of the banana arm 8 is a hydraulically operated piston-cylinder unit formed by a hydraulic cylinder 3 and a piston rod 21 for maneuvering the work tool. This hydraulic cylinder unit 3 is with its piston rod 21 fixed to the guide pin 9 in the track arm 8 and sits with its other end in a bearing device described in more detail below in the chassis 16 of the vehicle.

Med hjälp av hydraulcylindern 6 lyftes och sänkes lastarmen resp. lastarmarna 7 upp och ned. Hydraulcylindern 3 däremot användes för tippning resp. lägesinställning av arbets- redskapet 14 resp. l8. lAnvändes skopa l4 på lyftarmen 7 är det erforderligt, att kunna styra skopan på sådant sätt att den i sitt nedersta läge med sin underdel 19 förlöper parallellt med marken för att man skall kunna fylla skopan. När lastarmen_7 lyftes uppåt svänges skopan kontinuerligt bakåt kring axeln 15 såsom framgår av de olika skoppositionerna till vänster i övre delen av fig. l. Senast när lastarmens 7 översta ändläge uppnåtts tippas skopan framåt för tömning. För att medelst den ovan beskrivna armmekanismen kunna uppnå dessa olika skoplägen är framför lagerpunkten l anordnad en lagrings- punkt 2 och nedanför lagret l en ytterligare lagringspunkt 5. På hydraulcylindern 3 finns i dess längdriktning två efter varandra anordnade likadana lagerurborrningar 2' och 4, vilka möjliggör att förändra armmekanismens kinematik genom att vid användning av skopa enligt fig. 1 hydraul- cylinderns 3 lagertapp anordnas i lageröppningen 2' och införas i chassits 16 lagerpunkt 2. 8008328-Û För omställning till gaffeltruck anordnas namnda lagertapp för hydraulcylindern 3 i lageröppningen 4 och i den vid chassits l6 nedanför hävarmlagrets l anordnade lagerpunkten 5, varigenom truckgaffeln 18 i sina mot återgivningen till vänster i fig. l svarande lägen intar de till vänster i fig. 2 angivna inbördes parallellförskjutna lägena. rruckgaffelns le gaffelyta förblir således alltid i ett horisontellt läge oberoende av lyftarmens 7 rörelser, såsom _således framgår av fig. 2.With the help of the hydraulic cylinder 6, the load arm is raised and lowered resp. load arms 7 up and down. The hydraulic cylinder 3, on the other hand, is used for tipping resp. position setting of the work tool 14 resp. l8. If a bucket 14 is used on the lifting arm 7, it is necessary to be able to steer the bucket in such a way that in its lowest position with its lower part 19 it runs parallel to the ground in order to be able to fill the bucket. When the loader arm 7 is lifted upwards, the bucket is continuously swung backwards about the shaft 15 as can be seen from the various bucket positions on the left in the upper part of Fig. 1. At the latest when the top end position of the loader arm 7 has been reached, the bucket is tipped forward for emptying. In order to be able to achieve these different bucket positions by means of the arm mechanism described above, a bearing point 2 is arranged in front of the bearing point 1 and a further bearing point 5 is arranged below the bearing 1. In the longitudinal direction of the hydraulic cylinder 3 there are two identical bearing bores 2 'and 4 arranged one after the other. makes it possible to change the kinematics of the arm mechanism by using the bucket according to Fig. 1, the bearing pin of the hydraulic cylinder 3 is arranged in the bearing opening 2 'and inserted in the bearing point 2 of the chassis 16. in the bearing point 5 arranged at the chassis 16 below the lever bearing 1, whereby the truck fork 18, in its positions corresponding to the representation on the left in Fig. 1, assumes the mutually parallel offset positions indicated on the left in Fig. 2. The fork surface of the jerk fork thus always remains in a horizontal position independent of the movements of the lifting arm 7, as is thus shown in Fig. 2.

- Det är tydligt att de konstruktiva medlen som medger denna _ omställning är ytterst enkla och prisbilliga. Man behöver endast anordna två resp. tre ytterligare lagerurborrningar för att genom enkel omflyttning av lagerbulten på önskat sätt ändra anordningens kinematik.- It is clear that the constructive means that allow this _ adjustment are extremely simple and affordable. You only need to arrange two resp. three additional bearing bores to change the kinematics of the device in a desired manner by simply moving the bearing bolt.
