Description
Foreliggende oppfinnelse vedrører etsaksløftebord for løfting av The present invention relates to an etching table for lifting
lange eller tunge løft, hvor saksarmenes oppadrettede ender inngriper i en plattform og deres nedadrettede ender inngriper i en grunn- long or heavy lifts, where the scissor arms' upward ends engage a platform and their downward ends engage a base
ramme, idet endene er utformet som rulleender, og hvor en ytterligere arm i saksplanet med sin ene ende er leddet til plattformen og med sin andre ende er leddet til midten av den øvre arm av en saksarm. frame, the ends being designed as roller ends, and where a further arm in the scissor plane with its one end is the link to the platform and with its other end is the link to the middle of the upper arm of a scissor arm.
Det er vanlig ved kjente saksløftebord at saksens armer ved den ene ende, den såkalte festeende, er forbundet med enden av plattformen resp. grunnrammen, mens den andre ende, den såkalte rulleende, ved hjelp av f.eks. ruller eller tilsvarende anordninger er forskyvbare i føringer ved den andre ende av plattformen resp. grunnrammen. It is common with known scissor lift tables that the arms of the scissor at one end, the so-called attachment end, are connected to the end of the platform or the base frame, while the other end, the so-called rolling end, using e.g. rollers or similar devices are displaceable in guides at the other end of the platform or the basic frame.
Dette medfører at midtpunktet mellom de fire løfteender på plattformen forskyver seg mot festeenden ved løfting av plattformen. Dette er uten særlig betydning ved middels tunge eller lette løft, men ved lange og særlig meget tunge løft, vil dette for hånd føre til meget ujevn belastning på saksenes løftearmer, noe som i sin tur kan føre til deformasjoner og tillikebrudd. This means that the center point between the four lifting ends of the platform shifts towards the attachment end when the platform is lifted. This is of no particular importance for medium-heavy or light lifts, but for long and especially very heavy lifts, this will lead to a very uneven load on the scissor's lifting arms by hand, which in turn can lead to deformations and breakage.
Videre er det fra tysk utlegningsskrift 1080750 kjent et saksløfte-bord av den ovennevnte type hvor det er anordnet et ytterligere armpar mellom de øvre saksarmer på lignende måte som en nyrnberger-saks. Dette ytterligere armpar har til oppgave å stabilisere plattformen mot sideveis glidning. Det formår imidlertid ikke å hindre ujevn belastning på saksenes løftearmer. Furthermore, a scissor lift table of the above-mentioned type is known from German explanatory document 1080750 where a further pair of arms is arranged between the upper scissor arms in a similar manner to a Nuremberg scissor. This additional pair of arms has the task of stabilizing the platform against lateral sliding. However, it does not manage to prevent uneven loading on the scissor's lifting arms.
Det er derfor oppfinnelsens hensikt å tilveiebringe et saksløftebord It is therefore the purpose of the invention to provide a case lifting table
av den innledningsvis nevnte type, hvor ovennevnte mangel er opp- of the initially mentioned type, where the above-mentioned deficiency is
veiet ved at midtpunktet mellom de fire ender av armene som griper plattformen alltid holder seg på samme punkt på plattformen. Denne weighed in that the midpoint between the four ends of the arms that grip the platform always stays at the same point on the platform. This
hensikt oppnås ifølge oppfinnelsen ved at den ytterligere arm på purpose is achieved according to the invention by the further arm on
i og for seg kjent måte danner et støttearmpar som i den ene ende er leddet til samme punkt på plattformen og i den andre ende er leddet til'midten av den motgående øvre saksarm, at et ytterligere støttearmpar på speilvendt måte i forhold til det første støttearm-par er leddet til en felles dreieaksel på grunnrammen og er leddet midt mellom dreieakselen og de nedre rulleender på hver sin av de nedre saksarmer, og at minst en av de to dreieaksler for støttearm-parene anordnet på plattformen eller på grunnraimmen er høydeforskyv-bart lagret, fortrinnsvis i en loddrett kulisseføring, i et felles vertikalt plan gjennom saksdreieakselen. in a manner known per se, a pair of support arms which at one end is linked to the same point on the platform and at the other end is linked to the middle of the opposing upper scissor arm, forms a further pair of support arms in a mirror-image manner in relation to the first support arm pair is connected to a common pivot shaft on the base frame and is connected midway between the pivot shaft and the lower roller ends on each of the lower scissor arms, and that at least one of the two pivot shafts for the support arm pairs arranged on the platform or on the base frame is adjustable in height stored, preferably in a vertical slide guide, in a common vertical plane through the scissor turning shaft.
Ytterligere trekk ved oppfinnelsen vil fremgå av underkravene og av det utførelseseksempel som er vist på tegningen. Further features of the invention will be apparent from the subclaims and from the embodiment shown in the drawing.
På tegningen er driftsaggregater som hydraulsylinder, oljebeholder, elektromotor, pumpe osv. sløyfet for oversiktens skyld. In the drawing, operating units such as hydraulic cylinder, oil tank, electric motor, pump etc. are omitted for the sake of clarity.
På figuren er grunnrammen betegnet med 7 og plattformen med 6. Saksen 4 har armene 2. 2a er de øvre saksarmer og 2b er de nedre saksarmer. På midten mellom rulleendene 1 og dreieakselen 3 er det på begge saksarmene 2a, 2b svingbart hengslet ytterligere armer 5 i saksplanet. Den andre ende av disse ytterligere armer 5 er fast, dog i saksplanet svingbart forbundet med plattformen 6 resp. grunnrammen 7 på midten mellom de to rulleendene 1. Dreieakselen 9 ved denne ende kan være ført høydeforskyvbart i en kulisseføring 8 for å forhindre at plattformen 6 ved tunge løft bøyer seg slik at armene 2 og 5 skades på en eller annen måte. Det kan være hensiktsmessig å anordne de ytterligere armers 5 feste 8 på plattformen resp. stativet forskyvbar i sideretning i saksplanet. For dette formål kan kulisseføringen gjøres forskyvbar i tilsvarende anordninger under plattformen og forskynes med et drivorgan på siden, f.eks. en arbeidssylinder 10, In the figure, the base frame is denoted by 7 and the platform by 6. The scissors 4 have the arms 2. 2a are the upper scissor arms and 2b are the lower scissor arms. In the middle between the roller ends 1 and the pivot shaft 3, on both scissor arms 2a, 2b further arms 5 are pivotably hinged in the scissor plane. The other end of these further arms 5 is fixed, however in the case plane pivotably connected to the platform 6 or the base frame 7 in the middle between the two roller ends 1. The pivot shaft 9 at this end can be guided height-displaceable in a slide guide 8 to prevent the platform 6 from bending during heavy lifting so that the arms 2 and 5 are damaged in one way or another. It may be appropriate to arrange the attachment 8 of the additional arms 5 on the platform or the stand can be moved laterally in the plane of the case. For this purpose, the slide guide can be made displaceable in corresponding devices under the platform and offset with a drive device on the side, e.g. a working cylinder 10,
som muliggjør den forønskede forskyvning. Dersom de ytterligere armer 5 er fast, men i saksplanet svingbart forbundet med plattformen 6, får plattformen et ytterligere anleggspunkt. Dette betyr at plattformen, særlig ved store lengder, kan være utført smekrere .enn om den bare hadde to anleggspunkter. Dersom en saks bare er forsynt med en eller et par ytterligere armer 5, skal denne resp. disse inn-virke slik på plattformen 6 at denne ikke kan bevege seg mot saksene. which enables the desired displacement. If the additional arms 5 are fixed, but pivotably connected to the platform 6 in the case plane, the platform gets an additional anchor point. This means that the platform, particularly at long lengths, can be made more smoothly than if it only had two attachment points. If a scissor is only provided with one or a couple of additional arms 5, this or these affect the platform 6 in such a way that it cannot move towards the scissors.
