Abstract

FOre1iggande uppf inning avser en gripanordn1ng, fOretrOdesvis avsedd fOr att lasta, transportera och lossa massaved och/eller timmerstockar. Uppfinningen kannetecknas av att en knaledsmekanism (4,5) ar kopplad mellan gripklorna (1,2) p5 timse sidor om den gernensamma axeln (3) och att ett kraftalstrande don (7) ar kopplat mellan knatedsmekanismen och ena gripkIon (2). The present invention relates to a gripping device, preferably intended for loading, transporting and unloading pulpwood and / or logs. The invention can be characterized in that a knuckle mechanism (4,5) is coupled between the gripping claws (1,2) on 5 hours sides of the hinged shaft (3) and that a force-generating device (7) is coupled between the kneading mechanism and one gripping knob (2).

Description

f.) Gerioni att kunna placera hydraulcylinder-n i huvudsak centralt mellan de båda gripklorna, erhålles en rnycket gynnsam kraftgeometri. dvs krafttiver- föringen sker via ett rniriimitrii av havarmar och ledaxlar. f.) Gerioni to be able to place the hydraulic cylinder substantially centrally between the two gripping claws, a slightly favorable force geometry is obtained. ie the power transmission takes place via a minimum diameter of sea arms and articulated shafts.

Dessutom blir det niöjligt att få en stor klamkraft och en snabb öppnings~ rörelse mellan klorna, vilka egenskaper är önskvärda hos en gripariordriing av detta slag. uppfinningen skall nu beskrivas i anslutning till ett på bifogade ritningsblad visat utföringeexernbel, dar Figuren i perspektiv scnematiskt visar en grip-anordning enligt uppfinning~ en. ßripkiorna l och 2 ar sinsemellan rorligt ledade kring axeln 3. En knäledw mekanism 4 och 5 förbinder klorna l och 2 på ömse sidor om axeln 3.In addition, it becomes impossible to obtain a large clamping force and a rapid opening movement between the claws, which properties are desirable in a gripper arrangement of this kind. the invention will now be described in connection with an exemplary embodiment shown on the accompanying drawing sheets, in which the figure schematically shows in perspective a gripping device according to the invention. The ribs 1 and 2 are mutually rotatably hinged about the axis 3. A knee joint mechanism 4 and 5 connects the claws 1 and 2 on either side of the shaft 3.

Mellan tvarstagen 6 ocli 8 sträcker sig en dubbelverkande hydraulisk kolv- cylinde-ranordning 7, lnmatning av iiydraulvatska på anordningens +-si'da ger en kraftfull och långsam stangningsrorelse medan inrnatning på "sidan ger en snabbare och mindre öppnlngsrörelse hos de båda gripklorna.Extending between the transverse struts 6 and 8 is a double-acting hydraulic piston-cylinder device 7, feeding hydraulic fluid on the + side of the device gives a powerful and slow closing movement while grooving on the "side" gives a faster and smaller opening movement of the two gripping claws.

På knäledsrnekaiiismens ovansida kan en rotator placeras, Den gripgeometri som gripklorna l och 2 kommer att uppvisa är överraskan~ de gynnsam. klorna konimer att kunna öppnas så mycket. att deras spetsar kan vara riktade l huvudsak parallellt iiedât, vilket ar av stor betydelse för förmågan att kunna tränga in i exvis en iiiassavedsstapel, Nar klorna griper om lasten, koriimer denna att samtidigt förflyttas något uppåt, vilket på ett gynnsamt satt underlättar en iririillnirig av stockarna.A rotator can be placed on the upper side of the knee joint mechanism. The grip geometry which the grip claws 1 and 2 will exhibit is surprisingly favorable. claws konimer to be able to open so much. that their tips can be directed substantially parallel to each other, which is of great importance for the ability to penetrate, for example, a pile of sawdust. When the claws grip the load, it tends to move slightly upwards at the same time, which in a favorable manner facilitates an irrigation of the logs.

*Jppfiniiingeii ar inte begransad till det ovan beskrivna utföringsexernplet utan modifikationer kan göras inom .rarneli for de följande angivna patent- kravenJppfiniiingeii is not limited to the above-described embodiment but modifications may be made within the scope of the following claims.
