GRIPEANORDNINGGRIP DEVICE
Foreliggende oppfinnelse angår en gripeanordning, fortrinnsvis beregnet på å anvendes ved lasting og lossing av gods, såsom tømmer eller bulkmateriale. The present invention relates to a gripping device, preferably intended for use when loading and unloading goods, such as timber or bulk material.
Gripeanordninger for tømmer/masseved og øseanordninger for bulkmateriale har for det meste forskjellig utseende selv om selve den mekanisme som avstedkommer åpningsbevegelsen kan være den samme for de to konstruksjoner. Tømmergripeanordninger er i løpet av de siste tretti år blitt utviklet fra forholdsvis tunge konstruksjoner til stadig mindre og lettere konstruksjoner, der gripe- og bevegelsesgeometrien hele tiden er blitt mer formålstjenlig. Iblandt er imidlertid levetiden til de mer kompliserte mekanismer ved de moderne gripeanordninger blitt uakseptabelt kort samtidig som behovet for service har øket. Grabbing devices for timber/pulp wood and scooping devices for bulk material mostly have a different appearance, although the actual mechanism that causes the opening movement may be the same for the two constructions. Over the past thirty years, timber gripping devices have been developed from relatively heavy constructions to increasingly smaller and lighter constructions, where the gripping and movement geometry has constantly become more expedient. Sometimes, however, the lifetime of the more complicated mechanisms of the modern gripping devices has become unacceptably short at the same time as the need for service has increased.
En forklaring på denne negative utvikling kan formodentlig finnes i valget av bare én hydraulikksylinder. An explanation for this negative development can presumably be found in the choice of only one hydraulic cylinder.
Hovedformålet med foreliggende oppfinnelse er å frembringe en gripeanordning som både blir kompakt - lav byggehøyde - og samtidig oppviser en meget gunstig bevegelsesgeometri. The main purpose of the present invention is to produce a gripping device which is both compact - low construction height - and at the same time exhibits a very favorable movement geometry.
Et annet formål med oppfinnelsen er å frembringe en gripeanordning som oppviser en meget gunstig kraftgeometri. Another object of the invention is to produce a gripping device which exhibits a very favorable force geometry.
Et ytterligere formål med oppfinnelsen er å frembringe en gripeanordning som sammen med en konvensjonell rotator og en kran danner en meget effektiv anordning for lasting og lossing av masseved. A further object of the invention is to produce a gripping device which, together with a conventional rotator and a crane, forms a very efficient device for loading and unloading pulpwood.
Ovennevnte formål med foreliggende oppfinnelse oppnås ved at gripeanordningen omfatter de i patentkravene angitte trekk. The above-mentioned purpose of the present invention is achieved by the gripping device comprising the features specified in the patent claims.
Ved å kople dels en kneleddmekanisme mellom gripeklørne eller øsehalvdelene på hver side av deres felles leddakse og dels dobbeltvirkende hydraulikk-stempelinnretning mellom kneleddmekanismen og den ene gripekloen/øsehalvdelen, oppnås på en overraskende måte en velbalansert og hensiktsmessig gripe- By connecting partly a knee joint mechanism between the gripper claws or bucket halves on each side of their common joint axis and partly a double-acting hydraulic piston device between the knee joint mechanism and one gripper claw/bucket half, a well-balanced and appropriate gripper is achieved in a surprising way
og bevegelsesgeometri ved gripeklørne/øsehalvdelene.and movement geometry at the claws/bucket halves.
Ved å plassere to hydraulikksylindre på hver sin side avBy placing two hydraulic cylinders on opposite sides of
en sentralt beliggende holder for en rotator, oppnås en gunstig kraftgeometri, dvs kraftoverføringen skjer via et minimum av hevarmer og leddakser. Dessuten blir det mulig å oppnå en stor gripekraft og en hurtig åpningsbevegelse mellom gripeklørne/øse- a centrally located holder for a rotator, a favorable power geometry is achieved, i.e. the power transmission takes place via a minimum of lifting arms and joint axes. In addition, it becomes possible to achieve a large gripping force and a quick opening movement between the gripping claws/scoop-
halvdelene, hvilke egenskaper er ønskelig ved en anordning av angjeldende art. the halves, which properties are desirable for a device of the type in question.
Oppfinnelsen skal nå beskrives i tilknytning til et på vedlagte tegningsblad vist utføringseksempel, hvor The invention must now be described in connection with an example of execution shown on the attached drawing sheet, where
Figuren i perspektiv skjematisk viser en gripeanordning for tømmer i samsvar med foreliggende oppfinnelse. The figure in perspective schematically shows a gripping device for timber in accordance with the present invention.
Gripeklørne 1 og 2 er innbyrdes bevegelig leddet om akselen 3. En kneleddmekanisme 4 og 5 forbinder klørne 1 og 2 på begge sider av akselen 3. Mellom tverrstagene 6 og 8 strekker det seg en dobbeltvirkende hydraulisk stempel-sylinderanordning 7. Innmating av hydraulikkvæske på anordningens +-side gir en kraftfull og langsom stengebevegelse mens en innmating på --siden gir en hurtigere og mindre kraftfull åpningsbevegelse av de to gripeklør. The gripper claws 1 and 2 are mutually movably articulated around the shaft 3. A knee joint mechanism 4 and 5 connects the claws 1 and 2 on both sides of the shaft 3. Between the transverse struts 6 and 8 extends a double-acting hydraulic piston-cylinder device 7. Supply of hydraulic fluid on the device's The + side gives a powerful and slow closing movement, while an input on the -- side gives a faster and less powerful opening movement of the two gripping claws.
På kneleddmekanismens overside kan en rotator plasseres. A rotator can be placed on the upper side of the knee joint mechanism.
Den gripegeometri som gripeklørne 1 og 2 vil oppvise er overraskende gunstig. Klørne vil kunne åpnes så meget at deres spisser kan være rettet i hovedsaken parallelt nedad, hvilket er en stor fordel for gripeklørnes evne til ovenfra å kunne trenge inn i f.eks. en massevedstabel. Når klørne griper om lasten vil denne samtidig bli flyttet noe oppad, hvilket på en gunstig måte letter innrulling av stokkene mellom gripeklørne. The gripping geometry that gripping claws 1 and 2 will exhibit is surprisingly favorable. The claws will be able to be opened so much that their tips can be directed mainly parallel downwards, which is a great advantage for the grasping claws' ability to penetrate from above into e.g. a mass woodpile. When the claws grip the load, this will at the same time be moved somewhat upwards, which in a favorable way facilitates the rolling of the logs between the gripping claws.
Ettersom griperens hevarmpunkt er foranderlig i forhold til sylinderens befestigelse, er det fordelaktig å anordne denne midjemontert med mantelåkfeste for at den gunstigste kraftutvikling ved gripeanordningen skal kunne oppnås. As the gripper's lever point is changeable in relation to the cylinder's attachment, it is advantageous to arrange this waist-mounted with a mantle yoke attachment so that the most favorable force development by the gripping device can be achieved.
Midjemontering av hydraulikksylinderinnretningen skjer fortrinnsvis på begge sider av gripeanordningens verikale symmetriakse. Waist mounting of the hydraulic cylinder device preferably takes place on both sides of the gripper's vertical axis of symmetry.
Oppfinnelsen er ikke begrenset til de ovenfor beskrevne utføringsformer, idet modifikasjoner kan utføres innenfor rammen av de følgende angitte patentkrav. The invention is not limited to the embodiments described above, as modifications can be made within the framework of the following patent claims.
